Since Trotsky was responsible for negotiating with the People's Party, he and some comrades had also done a lot of homework, such as searching for materials in Moscow's huge database. After reading a considerable amount of cruel orders issued by Russia during its expansion in the East, Trotsky was not too surprised by the Hailanpao (Blagoveshchensk) Massacre. The Tsar had always had the idea of establishing "Yellow Russia," and this was just policy execution. If anything surprised Trotsky, it was probably the rise of People's Party China.

Before China fell into the disaster of total destruction, Chinese revolutionaries suddenly stood up to save the country with such a rapid posture, forcefully stopping the trend of China sliding into the abyss. If not for witnessing the results of these fruitful efforts with his own eyes, Trotsky would have thought that this was just a Chinese dream.

However, since China had begun to reverse its declining trend, the neighboring countries that once dared to treat China arrogantly clearly felt that days were getting harder. For example, the example of the massacre carried out by Russia cited by Zhang Yu. Such things would inevitably trigger a full-scale war between any great powers, and China and Russia could not be an exception.

So Trotsky asked calmly: "I wonder who the People's Party thinks should be responsible for this matter?"

Zhang Yu replied: "From the perspective of our People's Party, this is our own responsibility. We did not fulfill the obligation of defending the land and the country, which led to the fate of our compatriots being massacred. So no matter what, we must retake the land China lost, and then firmly guard China's territory."

The meaning in these words could not be clearer. The People's Party firmly stated that there would be no concessions on the border line issue.

Trotsky knew that it was impossible to influence the People's Party's attitude on the issue of China marching north. Since that was the case, what could be discussed was another issue. "If your side insists on going north, then your side will face Kolchak. I wonder what your side plans to do."

Zhang Yu frowned slightly, "Comrade Trotsky, haven't you discovered that the reason why we negotiate repeatedly with your side on this issue is that we firmly believe one thing: the Russian Communist Party will inevitably win the Russian Liberation War and become the final victor? If our attitude were not firm enough, then why would we waste so many words with your side on this matter?"

Trotsky was stunned. This was actually the view Comrade Lenin proposed to the Central Committee of the Russian Communist Party before this trip. Comrade Lenin predicted that the People's Party firmly believed in the victory of the Russian Communist Party, so the People's Party wanted to establish a relatively friendly relationship with the Russian Communist Party. The Russian Communist Party internally did not agree much with Comrade Lenin's prediction, but unexpectedly, Comrade Lenin's prediction came true again.

Ignoring Trotsky's silence, Zhang Yu continued: "The reason why we want to discuss this issue repeatedly with the Russian Communist Party is that we hope that when the army of the Russian Communist Party enters the East in the future, both sides will have reached an agreement on the border line issue. At that time, there will definitely be many small frictions between the two sides on the detailed determination of the border, but at least there will be no full-scale conflict in the general direction. I emphasize again, what we want to take back is only the territory taken by Russia. We do not want to start a meaningless war with the Russian Communist Party because of coveting Russian territory. That is worthless."

After Zhang Yu's explanation, Trotsky finally connected the internal logic of these statements by the People's Party. Regardless of what concerns the Russian Communist Party had, looking at the attitude of the People's Party from the written and verbal expressions all along, the internal logic was consistent.

The People's Party believed in the inevitability of the Russian Communist Party's victory, and also had the determination to retake the lost territory at all costs. Before a full-scale conflict with the Russian Communist Party broke out, the People's Party still wanted to reach an agreement with the Russian Communist Party on this issue through negotiation.

Whether it was the railway to Outer Mongolia, or the collection and summary of historical materials by the People's Party to mobilize the people to the greatest extent, or various drugs including "Divine Body Protection Pills," and even the discussions between the People's Party and the Russian Communist Party. All war preparations were being promoted step by step. If an agreement with the Russian Communist Party could be reached, the People's Party could obtain the territory they expected at the minimum cost. Even if the negotiation failed, the People's Party could completely start taking action unilaterally after preparations were completed.

Facing such a shrewd and calculating opponent, Trotsky suddenly became very puzzled. The information showed that Chen Ke was born in 1880. Trotsky was one year older than Chen Ke, and the core leaders of the People's Party were mostly younger than Trotsky. No matter how you look at it, they shouldn't be such a group of people. Are Easterners born with a longer-term vision than Westerners? Trotsky even gave birth to a feeling completely inconsistent with the basic theory of Marxism.

The meeting took a break here. Trotsky proposed to continue the negotiation two days later on the grounds of needing rest. Zhang Yu did not press step by step and immediately agreed.

Trotsky and the Russian Communist Party delegation conducted a comprehensive discussion on the current situation. The basis of the discussion became "The People's Party genuinely supports the Russian Communist Party as they said." However, another deduction result that greatly surprised the Russian Communist Party delegation appeared in the sand table deduction.

Even if the People's Party had no hostility towards the Russian Communist Party and no subjective malice towards Russia. However, once the Russian Communist Party reached a new border treaty with the People's Party, it would turn out that every attack by the Russian Communist Party on Kolchak objectively helped the People's Party reduce the pressure of marching north. The People's Party didn't even need to march north earlier than the Russian Communist Party. As long as they waited until the Russian Communist Party began to march into Siberia and the Far East, the People's Party could start later but arrive first, reaching the border agreed upon by both sides. Everything the Russian Communist Party did was working for the People's Party.

But if the Russian Communist Party was unable to destroy the White Army under Kolchak, it meant that the Russian Communist Party itself had not yet won the victory of the Russian Revolution, then the People's Party would have plenty of time to make calm preparations for the march.

So overall, the Russian Civil War itself was the root of the People's Party's profit. The more cruel the civil war, the more advantageous the position of the People's Party. In order to end the cruel civil war in Russia as soon as possible, it was difficult for the Russian Communist Party to refuse cooperation with the People's Party. Cooperation with the Russian Communist Party happened to guarantee the People's Party's profit to the greatest extent.

"This man Chen Ke is a devil!" Trotsky said angrily at the end of the deduction. Unless the People's Party suddenly collapsed like the German regime, this was an outcome of "counting money in a sack" that the Russian Communist Party could not avoid at all.

Comrade Belkov could only sigh; anger was meaningless. When the situation had reached this point, one could only pinch one's nose and accept it. In fact, according to the intelligence obtained by Comrade Belkov, didn't the People's Party also return home dejectedly without any gain at the Paris Peace Conference?

Of course, judging from Chen Ke's virtue, he must have made some more far-reaching layout. Even without actual proof, Belkov still firmly believed so. Therefore, Comrade Belkov wanted to persuade Comrade Trotsky to face the facts as realistically as possible.

The border negotiation was arduous and exceptional. Both Trotsky and Zhang Yu were firm in their attitudes. Trotsky demanded that the People's Party clearly support the Russian Communist Party. Zhang Yu refused immediately. And Trotsky also firmly disagreed with the border line demarcation of the People's Party. After arguing for a few more days, the meeting adjourned again.

After the Russian Communist Party delegation realized that the People's Party could not make concessions on the border line demarcation at all, after internal discussion, they finally came up with a more pragmatic attitude after the adjournment.

First, they asked the Chinese side for the production method of "Divine Body Protection Pills." The huge effect after taking the medicine left a deep impression on the Russian side.

Zhang Yu specially invited a Chinese military doctor who had returned from France to introduce specifically the side effects after the British and French troops took the medicine. Taking medicine would only make the army a "disposable army." The military doctor explained various side effects brought by the drug to the Russian side. "The biggest problem with this drug is that psychological dependence is extremely difficult to break. In other words, after using this drug, a person is like a mental patient. You have to treat them in the way of treating mental illness. I believe the comrades of the Russian Communist Party would not want the troops to become a mental patient troop, right?"

"Then what experience do Chinese comrades have in treatment?" Trotsky felt that the Chinese military doctor's words were too wonderful.

"We only developed this drug; we don't use this drug domestically." The military doctor replied.

The faces of Trotsky and other Russian Communist Party representatives immediately showed disapproval. These words were not convincing at all.

However, the military doctor of the Workers' and Peasants' Revolutionary Army didn't want to explain too much. After witnessing the terrible situation on the Western Front battlefield in Europe during World War I, any explanation seemed very pale and feeble. Some things must be seen with one's own eyes to know how terrible the world is.

However, under repeated requests from the Russian side, the People's Party finally agreed to provide a drug formula called "Amphetamine." The military doctor repeatedly emphasized that the biggest consequence of using this drug is that long-term users may never feel happiness again.

Regarding such psychological stuff, Trotsky and the Russian Communist Party side didn't care too much. In such a cruel world, actually emphasizing pure personal feelings like happiness really made the Russian Communist Party unable to understand what the People's Party was thinking. What the Russian Communist Party negotiators cared about most was that the People's Party stated that it would not provide any such drugs to the Entente Powers and the Russian White Army.

After reaching an agreement on this practical issue, after a series of discussions, Trotsky made the People's Party agree to give up part of the territorial demands. For example, the border line proposed by the People's Party originally reached Lake Baikal. Now, under Trotsky's strong arguments, the People's Party decided to give up the territorial claim around Lake Baikal. However, the two sides reached some intentional ideas on economic cooperation and personnel flow.

What surprised Trotsky even more was that the People's Party actually proposed a non-garrison agreement on the border. That is to say, due to the geographical location of the new border, apart from border patrols and police forces, the People's Party could even accept a 2:1 ratio of garrison troops on the Russian side to the Chinese side. Since Russia faced pressure from the United States and Japan, China could even accept the situation where there were more garrisons on the Russian side in the Far East.

"If possible, we don't want to invest any military force on this long border line. The cost is too high." Zhang Yu emphasized again, "A peaceful Sino-Russian border is a great thing for both sides. Comrade Trotsky, as long as both China and Russia are industrial countries, the struggle for small pieces of land cannot last too long at all. If it is a large-scale war aimed at eliminating the other side, don't you think this is a nightmare for the attacking side?"

As one of the founders of the Red Army, Trotsky certainly knew what a nightmare it was to wage war across thousands or tens of thousands of kilometers. Millions of troops fighting on such a long battle line, small troops could attack the enemy's rear at will, destroying railways and blowing up bridges. Anyway, no matter what the Chinese side thought, for Russia's Trans-Siberian Railway, it simply couldn't withstand such constant damage unless Russia used hundreds of thousands of troops to protect the railway. Of course, hundreds of thousands of troops protecting the railway day and night would itself make the war extremely ridiculous.

Finally, the two sides reached an intentional agreement. Many more detailed and even more "interesting" technical consultations that needed to be considered were left for subsequent discussions.

Before Trotsky prepared to go back to report to the Central Committee of the Soviet Communist Party, Zhang Yu told Trotsky that the People's Party was preparing to march into Central Asia. Of course, such a march would strictly abide by the border line proposed by the Chinese side.

When Trotsky finally returned to Moscow, it was already December. The White Army's offensive had reached a frenzied level. On the snow-covered Eastern Front, the White Army launched continuous fierce attacks on important cities in the Soviet Communist Party's liberated areas. No matter how many warnings and precautions were written in the drug introduction of the People's Party, the Soviet Red Army still used the "gift" forcibly demanded by Trotsky from the People's Party without hesitation.

The effect of large-scale use was indeed very good. Even when taken orally according to strict dosage standards, the Red Army troops with low morale tortured by war greatly relieved their mental pressure. Even in the 1970s of Chen Ke's time and space, these drugs were originally drugs for treating mental conditions in the military and special industrial sectors. The Russian Communist Party at least didn't treat the troops as consumables. Although this drug had to be used, they still paid considerable attention to the dosage when using it.

The White Army inhaled "Divine Body Protection Pills," and the Red Army took "Ten-Complete Great Tonic Pills" orally. Both sides jumped directly from the World War I era to the World War II era in military drug technology. During the Patriotic War, both the German army and the Soviet army took such drugs. Of course, this level of military drug technology hadn't reached the level of the US military in the 21st century. The US military used drugs extensively in the wars in Afghanistan and Iraq, forcefully creating hundreds of thousands of soldiers suffering from so-called "battlefield syndrome." To cover up the shame, the Americans found a bunch of excuses from depleted uranium bombs to various confusing things. In fact, as long as the "refreshing pills" before battle and the "sleeping pills" during rest were cancelled, the number of American "battlefield syndrome patients" should drop by an order of magnitude.

Since the gap with the White Army was leveled in drug taking, the advantage of the Red Army in people's war was brought into play. In March 1920, the Red Army launched an attack on Kolchak's troops again, and Kolchak failed to withstand it again. Of course, this was also very likely because the stock of "Divine Body Protection Pills" from Britain and France was exhausted, and the People's Party refused to continue providing such drugs.

In May 1920, Kolchak's troops were defeated. The remnants fled across the Ural Mountains and routed towards the east.

In July 1920, Chen Ke's paper on "Methamphetamine Chiral Carbon and Organic Compound Chiral Carbon Research" was published, and patents were registered and applied for in various countries. This caused a not-so-small sensation worldwide. The major imperialist powers didn't expect that the military drug formula they coveted so much was obtained so easily.

Of course, not surprisingly, after the Nobel Prize in Medicine, Chen Ke ascended the throne of the Nobel Prize in Chemistry again in 1921. This was the second of the four Nobel Prizes in Chen Ke's life. Of course, the wave of criticism against Chen Ke as a "devil chemist" also began to appear in 1921.

This is a story for later.
