In the spring of 2000, a construction team was digging at the site of the 731 gas bunker, but Jin Chengming stopped it.The person in charge of the other party took out the government approval document from three years ago, but Jin Chengming refused to recognize it and stopped it with his own life. The farce ended when Yamabe Yukiko arrived.Yamabe Yukiko brought a paper document. The paper was accompanied by the serial number and military insignia at that time, which could prove that it was a document of the Kwantung Army.The evidence and witness testimony form a closed loop, but this evidence can only prove that they used bacterial weapons, but cannot prove that they conducted human experiments in China. There is still one missing piece of the evidence puzzle.

On New Year's Day in 1942, Tong Changfu went to Jichuan Trading to get goods and secretly mixed poison into the apples.Tai Nai and Yulan took Guifen to get ready to take the bus, but Guifen gradually became sweating profusely. She wondered if she was going to give birth, but Guifen said there was still a long time to go.This ticket was earned by Tong Changfu with his life and cannot be delayed.Yulan had no choice but to continue on her way.Passing the Russian cemetery, I met Japanese soldiers.One of the Japanese soldiers recognized Yulan and forced them to stop.During the scuffle and pushing, Magnolia's backpack fell to the ground, revealing the special directory inside.

The key was Tai Nai's strength. He stabbed the Japanese soldier to death with an arrow, took his pistol, and killed another Japanese soldier. Then they immediately detoured and left.Here, Tong Changfu, who was delivering the goods, did not expect that Narita Kazuo would suddenly ask everyone to enter Unit 731 to receive the prizes. Tong Changfu wanted to leave but was pointed at a gun by the Japanese soldiers behind him, so he could only step into this place where demons gathered.The Japanese gave them a bowl of broth. Tong Changfu found the food tasteless and asked Narita Kazuo when he could leave, but Narita Kazuo seemed not to have heard and refused to answer.

Tai Nai drove back to Bienzizi, but Guifen was about to give birth on the way. She had no choice but to give birth in the street.Arakawa was scheduled to be the first to speak on the program, and at this moment, he went out of his way to speak a few lines of poetry indicting the crimes of 731.Ishii Shiro asked people to control Arakawa Ryohei and continued to use words to encourage those soldiers.Immediately afterwards, everyone who drank the broth foamed at the mouth and fell into coma, including Tong Changfu.Huang Chuang yelled at Tong Changfu on the stage to run away, but Tong Changfu was already poisoned and fell to the ground without closing his eyes.

After Tong Changfu left and came back, he told his wife that the name of the child was Tong Fulai. He said that in the spring, the swallows and geese would fly back, and when the child grew up, they would also be able to come back and find all the things they had lost.The moment Tong Changfu's life ended, another life between him and Guifen was born, which was a continuation in a sense.Arakawa was extremely disappointed with Japan and Unit 731. He saw Narita Kazuo throwing all the mutilated Chinese corpses into a pit.He ate a poisoned apple and died of poison while lying next to Tong Changfu's body.

When Japan surrendered, Yulan sent out the special list in her hand. This special list was transferred to the Heilongjiang Archives and was dug out from piles of files by Jin Chengming after 2000.Later, this became important evidence that Unit 731 conducted human in vivo experiments.In 2002, the lawsuit went to trial again. The plaintiff's evidence was conclusive and the defendant, the Japanese government, had no defense. However, the judge in court rejected all the plaintiff's claims with outrageous reasons.Yamabe Yukiko said that it is very difficult for a country to admit that it has made mistakes.However, this piece of history cannot be buried easily, and the Japanese government will always suffer retribution one day.

Time came to the summer of 2024. A Japanese came to the 731 site to apologize, and Jin Chengming took him around.Tong Changfu's daughter, Tong Changfu, has become an octogenarian. Her father was murdered by 731, and she waited for the day when Japan apologized, and brought light and truth to her father.
