Even I, who was already famous at that time, only came into contact with people from the Criminal Investigation Bureau. This is far from sufficient for the investigation of all incidents. The white snow made Du Lei's heart even more hesitant. He has been hesitating, hesitating, and there is also uneasiness in his heart.

It wasn't a snowstorm, it was a bad sign.

Sure enough, suddenly one day, Xu Yi found Du Lei, just a few days before the 330 case. Du Lei still remembers that on that day, Xu Yi looked melancholy, and his hair, which was usually neatly combed, also looked a little messy. Du Lei asked Xu Yi what happened, and Xu Yi suddenly burst into tears.

Xu Yi knelt on the ground and confessed to Du Lei, to Du Lei's surprise, the reason why Xu Yi repented was because of his parents. Soon, Du Lei found a thick envelope in Xu Yi's hand, the envelope had been torn open, Xu Yi had been crying, Du Lei snatched the envelope in Xu Yi's hand, and inside was several pieces of stationery and a few black and white photos.

The photo turned out to be a group photo of eight people, among them, there were Cui Yunyi and Xu Rongzheng. And that letter actually explained everything that happened back then, from the formation of eight people, to the accident that happened 20 years ago, to Shen Shikang's betrayal, Xu Rongzheng and Cui Yunyi secretly built an abandoned factory to conduct human experiments on biological and chemical weapons, all of which were clearly explained.

It seems that it was to make Xu Yi believe, so the person who sent the letter put the group photo of everyone in the envelope. Not only that, but the letter also mentions a lot of things that happened to Xu Yi when he was a child, including the inside story of the death of Xu Yi's parents. Every word in the letter is completely consistent with what happened in Xu Yi's memory.

Anyone who knows this letter is definitely not groundless. Even, one of the photos is a recent photo of Cui Yunyi. Cui Yunyi in the photo has been disfigured, but because of the angle of shooting, the photo is still clear, and Xu Yi recognized it, that is, her mother who had already "died".

It turned out that the mastermind behind the scenes had always known that Cui Yunyi was not dead, and that he kept this person, just treating her as a pawn. This letter has made Du Lei have no way to hide it. Because of her parents' fault, Xu Yi didn't come to me, except for me, the only thing she could find was Du Lei.

This is also what Du Lei is happy about. Du Lei approached us with a purpose, but at that time, he had already decided not to drag us into the water. If I knew, one more person would fall into the trap. Du Lei helped Xu Yi well, told Xu Yi everything that happened back then, and also told him the truth about his hidden strength.

Since there was no way to hide it, he could only stabilize Xu Yi and let himself have a helper. Du Lei suddenly made a bold decision. At that time, Du Lei was worried about not knowing how to move next, and soon, he made a decision. The end of the letter is: I want to see Cui Yunyi, I want to atone for my parents, and three days later, I took the last train of the 330 bus.

Du Lei made a judgment: The mastermind behind the scenes will never kill Xu Yi. The mastermind behind the scenes wants to kill someone, it's very simple, and it will definitely not beat around the bush. Du Lei knew that the mastermind behind the scenes would definitely keep Xu Yi's life, either to control it, or to have other effects. Du Lei decided to get on the bus with Xu Yi.

Du Lei is also taking risks, and he has made sufficient preparations for this adventure.

Fortunately, no one knows Du Lei's true ability, including the mastermind behind the scenes, and I am afraid that Du Lei was just an incompetent person at that time. The mastermind behind the scenes, the first to start, started from Xu Yi. In those days, Du Lei made a lot of preparations through Zhou Ling's forces and through Luo Xi.

At that time, the person who took over Zhou Ling had not changed much, and at the beginning, he was very cooperative with Du Lei's actions. Du Lei didn't know where the 330 bus would eventually go, so Du Lei let the people in Zhou Ling's forces lurk in the periphery of City B, and if there was no situation, he would track it, and if there was a situation, he would save people.

Du Lei didn't dare to let people lurk in the city, he was afraid that he would be seen through by the people behind the scenes. On the other hand, Du Lei officially began to use Luo Xi. At that time, it coincided with the death of Dean Luo in the orphanage, and there was no one in the orphanage worthy of Luo Xi's gratitude, and on the day Dean Luo died, Luo Xi left the orphanage.

I remember that the results of the investigation at that time were exactly in line with what Du Lei said. At that time, the investigation learned that when Dean Luo died, Luo Xi locked himself in his room. Everyone indulged in the grief of Dean Luo's death, only to find out later that Luo Xi had left. It turned out that at that time, Luo Xi had already started to do things for Du Lei.

Luo Xi was born in an ethnic minority, participated in hunting since he was a child, and had a strong physique, although he was only a teenager at the time, his body shape was not much different from that of an adult. Du Lei disguised him as a mysterious man, and through the concealment of his appearance, no one could see that the mysterious man was only a teenager.

After several years of training, Luo Xi's marksmanship is already very superb, but after all, it is the first time to participate in the operation, and Du Lei is still not at ease. However, later results proved that Du Lei's trust was worth it. Let Luo Xi pretend to be a mysterious man, but also to let everyone completely separate Du Lei from the mysterious man.

The mysterious man is Du Lei. When he rescued Du Yan, he was already dressed up like that. When Du Lei and the mysterious man appear at the same time, no one will suspect that the mysterious man is Du Lei. Later, the trick he used in Yu City was the same reason, but when he set up a situation on Uncle Fan, the mysterious man was Du Lei, and Du Lei in everyone's eyes was just Du Resentment.

Du Lei and Xu Yi didn't expect that a 330 case would cause so many things later. Their ideal outcome is to be able to pass through that bus, see the mastermind behind the scenes, and kill the mastermind by surprise. However, they were all wrong.

In those days, Du Lei and Xu Yi deliberately accumulated the tasks in their hands, and on the night of the incident, they had a fair and honest reason: to work overtime.

That night, the weather was unusually cold, and Du Lei and Xu Yi waited for the last train at the bus stop as if nothing happened. The last train arrived nearly half an hour later than usual. Du Lei speculated that the mastermind behind the scenes did not do it for a long time, probably because of his intervention.

At that time, the target of the mastermind behind the scenes was obviously only Xu Yi alone. However, Du Lei was not in a hurry, he had enough reasons to wait for the bus with Xu Yi, on the one hand, because they were on the way, and on the other hand, Du Lei was indeed working overtime. Eventually, the bus appeared.

The mastermind behind the scenes seemed to accept Du Lei's intervention after hesitation. In the eyes of the mastermind behind the scenes, Du Lei is just an incompetent person. The bus stopped, Du Lei got on the bus without any hesitation, it was Xu Yi who hesitated, Xu Yi hesitated for two seconds, and still stepped on the bus.

It was a medium-sized passenger car about six meters long. It was very late, and there were very few people in the car, but Du Lei soon found that everyone in the car was in a coma except for the driver. Du Lei remembered that there were six people in the car at that time, including the driver, and eight people including him and Xu Yi.

The driver, the mask-wearing, the passenger wearing the mask, and two people. When the driver was driving, his hands kept trembling, and Du Lei caught a glimpse of this scene out of the corner of his eye, and he knew that the driver might be controlled. Other people's lethargy may be real, while a few people wearing masks may be fake.

The doors and windows of the car were closed, and Du Lei guessed that there might be some kind of comatose gas in the car.

Du Lei wanted to open the car windows casually, but he found that all the windows were sealed. Du Lei's heart began to tense, once he and Xu Yi were also unconscious, they became passive in the rest of the matter. And once they force themselves out of the car, it can be safe, but all actions will be in vain.

Du Lei still firmly believes that the mastermind behind the scenes will not attack Xu Yi, so he made a more risky decision: continue to stay in the car. In fact, Du Lei should have known that when they decided to step on the 330 bus, it was the point of no return.

Soon, Du Lei and Xu Yi both fell asleep grogily.

The later things were all said by Du Lei listening to people in Luo Xi and Zhou Ling's forces.
