When the bell rang for the end of class, Professor Zhu stopped lecturing, and the content of his lecture today was the principles of basic mechanics. Professor Zhu is very young, in fact, he is in his early forties, and intellectuals who have been immersed in the world of learning for a long time always seem much younger than their actual age......

He gave a lively and humorous lecture, which was very popular with the students, and before the class, he actually asked the students a literary question: "Students, can any of you describe the strength of the power, using the simplest words or words." ”

"Isn't this a course in the principles of mechanics?"

"What's going on today, Professor?"

"Looks like it's going to test our national language level?"

.......

After he finished the lecture, he wrote an "N" on the blackboard and said: "'N' is 'ox', which is the unit of measurement of strength - 'Newton'. We Chinese students should be able to understand this problem better, you see, in the Chinese characters left by our ancestors, didn't we just say that the power can be described as nine cows, and the power is greater, we may use 10 cows, 100 cows, 1000 cows! Our Chinese culture is really 'cattle'. ”

He spoke with a simple and humorous voice, and the students were fascinated by it. Halfway through, the academic secretary came to the classroom window, and it should have been the communication room to call the academic affairs office, and the academic secretary came to confirm whether Professor Zhu was still in class.

"There's a guest visiting." Secretary Xiao Wang said.

"Well, what kind of guest is it?"

"I didn't elaborate, I just said that it was your old friend."

Professor Zhu frowned, and said in his heart: "This Zhuo Shaoqing, how can he go and return, how much trouble do you have to create for me to be happy, and the rest of the wine will definitely not be given to him again." ”

He turned to Secretary Xiao Wang and said, "I'll go to the lounge to rest first." ”

He walked briskly to the lounge and unscrewed the door with his left hand. The window of the lounge was facing his face, and the light was shining in from the opposite side, so that he couldn't open his eyes for a while. The window was catching up on the midday sun, "It's too bright......," he muttered.

So he went to the window, and was about to close it, when suddenly he poked his head out of the window and looked out of it.

"This ......" He suddenly felt lightheaded, the wind blowing his head a little painful, he closed the window, the more he felt that something was wrong, he fell, fell softly against the edge of the wall, and at this time, he could not use even the strength of a "cow".

He heard the footsteps and conversations of several people in the distance. One of the voices said, "It's just the right time, Professor Zhu is out of class." ”

Another voice asked, "What is the break between lessons?" This is Wu Tongguang's voice.

"More than 15 minutes, less than 10 minutes, alternating with each other, looking at this time, it should be a 15-minute break."

The visitor was about to open the door to the lounge, but he had no strength to call for help.

He couldn't believe that the light he opened the lounge was the last light he had ever seen in the world.

What he didn't expect was that the mechanics content he taught today would become an accomplice to kill him.

He could no longer help his friends and put away that important thing.

When it comes to the entanglement of Zhuo Shaoqing, Li Qingfeng, and Zheng Biwan, we can't help but look back on that turbulent history.

At that time, the Japanese imperialists launched a war of aggression against China, the enemy was strong and we were weak, and the situation in the early stage of the war was fundamentally one-sided, and the Japanese invaders soon occupied part of China's rivers and mountains, and the Kuomintang government was in a precarious situation at that time, and called on the whole nation to unite and unite in the war of resistance.

The Japanese country was already the size of a palm and had a small population, but they wanted to swallow the elephant and fought for a while, but they found that China's land was too vast and that they themselves had no way to exercise direct rule over the areas they occupied.

At that time, Wang Ching-wei, a veteran of the Kuomintang, was a guy who dreamed of being the boss, and he was invincible in the struggle for power with Chiang Kai-shek, and seeing that he had no hope of being the boss in the Kuomintang, he turned around and surrendered to the Japanese, became a puppet government, and became addicted to being the boss.

Many events in history have proved that it is impossible for a traitor government to be stable, so Wang Jingwei was anxious to establish a powerful spy organization to deal with the national progressives who resisted Japan and opposed the puppet government.

At that time, Wang Jingwei had a deputy named Zhou Fohai, who was a big traitor who single-handedly planned the establishment of a puppet government, and he almost didn't recognize the Japanese devil as his father.

Under the command of Zhou Fohai, Li Shiqun, who had been engaged in spy work for a long time, extended an olive branch to a man named Ding Mocun.

Ding Mocun joined the Communist Youth League and also served as an intelligence and transportation officer for Chen Duxiu, the general secretary of the Communist Party of China, but later broke away from the CCP and joined the Kuomintang, embracing the thigh of Chen Lifu, a powerful figure in the Kuomintang. Because the CCP's intelligence work has always been excellent, when the Kuomintang established the "Old Military Statistical Survey Bureau," it favored recruiting intelligence personnel from the Communist Party to defect to the past, and Ding Mocun was one of the examples.

At that time, the "Old Military Statistical Survey Bureau" was a unified secret service agency of the Kuomintang, which consisted of three divisions, the first division was Xu Enzeng, the second division was Dai Li, and the third division was Ding Mocun.

After Ding Mochun defected to the Kuomintang, he became a spy leader on an equal footing with Xu Enzeng and Dai Li, and at this time he felt that his future was bright. Unexpectedly, after the infighting in the three departments, Dai Li was afraid that Ding Mocun and Chen Lifu were too close, so he lobbied Chiang Kai-shek to abolish the third department, and the team of the first department led by Xu Enzeng established the "Central Unification", and the second department led by Dai Li established the "Military Unification", Ding Mocun instantly lost his power, felt that the happy days had come to an end, and was sent to Kunming to take up an idle post.

With the establishment of a puppet government by Wang Ching-wei and the co-opting of a large number of former agents in the "Central Unification" and "Military Unification," for a time the Kuomintang intelligence personnel were uncertain, and almost every day in the "Central Unification" under the jurisdiction of Xu Enzeng would hear a report: "Mr. Xu, someone has defected again." ”

The Kuomintang sent Ding Mo Estate south to Hong Kong, Guangzhou, with the intention of admonishing the defectors, but who knew that this Ding Mo Estate not only did not bring others back, but was also dragged into the water by Li Shiqun, who was loyal to the Japanese and became the number one spy leader under Wang Ching-wei.

Ding and Li set up a spy headquarters at No. 76 Jisfeier Road in Shanghai, specializing in killing anti-Japanese righteous soldiers and attacking patriotic and progressive forces, and were known for their cruel methods and bloody actions, and for a time "No. 76" became synonymous with "terror" and "devil's cave" in the hearts of the common people.

The strength of "No. 76" increased rapidly, repeatedly sabotaged the War of Resistance Against Japan, and also brutally attacked the Kuomintang intelligence personnel in Shanghai, Tianjin, Nanjing and other places, and even the head of the Shanghai Station of the Military Command was arrested.

I've seen anti-water, but I've never seen it so ruthless. It's good for you to kill the underground party of the CCP, why do you still bite the old club? Niang Xipi, how can this be endured by the chairman!

Zhuo Shaoqing, Li Qingfeng, and Zheng Biwan met at that time, and the three of them worked together to assassinate important personnel and representatives of the Japanese army in Shanghai, Tianjin, Nanjing and other places many times, and formed a deep friendship.

After the end of the War of Resistance Against Japan, the Kuomintang wanted to implement dictatorship, which was incompatible with the Communist Party, and the civil war broke out, with Li Qingfeng and Zheng Biwan each their own masters, becoming antagonistic.
