354384！

This is the fact that Wen Jike wanted to tell us in the end, Han Yu's first reaction to this line of numbers was the student number, which reminded me of the tattoos on the soles of Nie Bingwan and He Lianyi, Wen Jike would rather die than blow up the teaching building, but he knew that the bomb on his body had no effect at all, and what made us even more puzzled was that he actually didn't think about killing me and Yun Duruo at all.

He seemed to have deliberately left this line of numbers, and we immediately went back to the room to find the student records we got from Hua Guanwen and began to compare the student numbers that matched the numbers.

Chen Zhitai!

Han Yu's idea is right, at least we really found the student number that matches the number in the student registration file, and the corresponding name of this student number is Chen Zhitai, this is a student who studied at Hede Medical College thirty years ago, we found the address on the file, Nangong Yi sent someone to this address to verify, and the police officer who came back reported that the address in the student registration was demolished thirty years ago, and the people who once lived there are now impossible to check.

"The arrangement of the student number is convenient for allocating the dormitory, just like Helianyi's student number Zhu Jie remembers, if you can't find Chen Zhitai, you can check with his classmates in the same dormitory." Yun Duruo said smartly.

We found the closest person to us in the student registration file, Wang Chengrong was the director of the nearby county hospital after graduation, when we knocked on the door of his office, Wang Chengrong, who was in his fifties, looked at us in surprise, and when Nangong Yi showed his ID, he was even more dazed and didn't know what was going on.

When the prince brought Wen Jike's photo to Wang Chengrong, he blurted out with only a frown.

Chen ...... Zhitai, this ...... This is Zhitai, where did you find him, I haven't seen him for more than 30 years? ”

We all looked at each other by default, who would have thought that this would be the result, that Chen Zhitai, who forged all the files and pretended to be deaf and dumb, and even changed his name, was Wen Jike, and what surprised us even more was that he was actually a student of Hede Medical College, no wonder he knew how to use medicine.

Judging from Wang Chengrong's reaction, he didn't know what happened to Chen Zhitai, but he was even more excited than us and eager to know where he was.

"Can you tell us about Chen Zhitai?" Yun Duruo asked seriously.

Wang Chengrong was still looking at the photo in his hand, and sighed silently and said sadly.

"I haven't seen you for thirty years, how can you be old like this, where is this Chen Zhitai, who was high-spirited back then, hey......"

Wang Chengrong closed the door and invited us to sit down, slowly put the photo on the table, hesitated for a long time and then let out a long sigh.

"Chen Zhitai and I have a very good relationship, he is smarter than me and much better than me, we originally agreed to work hard after graduation, he is such a strong person who does not admit defeat, if it weren't for that incident......"

"What's the matter?" I saw that Wang Chengrong wanted to speak, but stopped, and hurriedly asked.

"Chen Zhitai and I studied clinical medicine, and we were admitted to Hede Medical College together and went to graduate school together, everything was originally developing according to the plan, until the appearance of He Xiaoyu changed everything."

"Who is He Xiaoyu?" I asked blankly.

"It's our counselor, in fact, he was about the same age as us at the time, He Xiaoyu is the kind of girl who is very spiritual, giving people a sunny and bright feeling, Chen Zhitai and He Xiaoyu fell in love with each other in the process of interacting with each other." Wang Chengrong said in a slow tone.

"Chen Zhitai fell in love with his teacher?" Yun Duruo was a little surprised when he heard this.

"Although He Xiaoyu was our counselor at school, and the teacher-student relationship was forbidden at that time, He Xiaoyu was able to become a counselor at Hede Medical College at such a young age because she was extremely accomplished in psychiatric treatment." Wang Chengrong nodded and continued. "At that time, President Mo was still alive, and he and Dean Jiang had high expectations for He Xiaoyu, and they did not forget to bring He Xiaoyu even to treat severely mentally ill patients."

"Do you mean the critically mentally ill patients who are admitted to the basement ward under Building 19?" Nangong Yi asked seriously.

"Yes, those people are not only patients but also murderers, all of them are very dangerous, but the cases of these patients are very representative, and studying and treating these patients will accumulate a lot of rare experience." Wang Chengrong rubbed his forehead with a heavy face and said. "But if there is a teacher-student love in the school rules, both parties will be expelled, although Chen Zhitai and He Xiaoyu are truly in love, but Chen Zhitai knows that He Xiaoyu does not want to miss such a rare opportunity, and He Xiaoyu does not want Chen Zhitai to delay his future because of the relationship between the two."

"So the relationship between the two has always been very hidden." Han Yu asked thoughtfully.

Wang Chengrong nodded slowly, and continued to talk to us, Wang Chengrong is the only person who knows this secret, Chen Zhitai is his best friend, sometimes when he wants to see He Xiaoyu, Wang Chengrong helps to cover, Chen Zhitai will graduate in another year, and then he will be able to be with He Xiaoyu in the open.

But who knew that there was a major accident in the school, one day Dean Mo and Dean Jiang, He Xiaoyu and another teacher went to treat a patient when they had an accident, and He Xiaoyu unfortunately died in that accident, and in the end even the body was not found.

Hearing this, I think Wang Chengrong should be talking about the patient riot that happened in Hede Medical College thirty years ago, and Jiang Xinyu has already told us the details of this matter, including Mo Yongyuan and Jiang Xinyu and two other people who went to the ward together at that time, He Xiaoyu should be one of them.

Jiang Xinyu was disfigured in the fire caused by the riots, while Mo Yongyuan and two other doctors were burned to ashes in the fire, and Jiang Xinyu was reluctant to rebuild Building 19 because she remembered that there were ashes of Mo Yongyuan and his colleagues in it.

"What happened to He Xiaoyu after the accident?" Han Yu asked.

Wang Chengrong sighed heavily, his eyes fell on the photo of Chen Zhitai on the table, shook his head weakly and continued, He Xiaoyu's death hit Chen Zhitai very hard, he was never able to come out of his grief and began to gradually become depressed, he had no fighting spirit and learned to drink all day long, Wang Chengrong's many persuasions were to no avail, Chen Zhitai would rather be drunk than face reality.

Later, Chen Zhitai began to skip school, Wang Chengrong tried his best to cheer him up, but it had no effect, Chen Zhitai would go to the place where He Xiaoyu died every night to sit alone, he hoped that a miracle would happen and hoped that nothing had happened.

"One day...... I remember that it was night, Chen Zhitai suddenly came back to wake me up, that time he didn't drink, since He Xiaoyu passed away I saw him awake for the first time, that day Chen Zhitai was very excited and excited, he told me...... "Wang Chengrong said this a little hesitant, his expression began to become worried.

"What did Chen Zhitai tell you?" I asked eagerly.

"He told me...... He saw He Xiaoyu! Wang Chengrong shook his head weakly.

"He Xiaoyu has not been killed, he ...... How could he see He Xiaoyu? Yun Duruo looked at Wang Chengrong in surprise.

"There is a rumor at Hede Medical College that we all heard when we went to school." Wang Chengrong lowered his voice and said slowly. "It is said that there is a passage to the underworld in Building 19, and if the nineteenth staircase appears, the passage will be opened and the wish will come true...... None of us believed these rumors, but Chen Zhitai has been convinced since that time. ”

I involuntarily squirmed my Adam's apple, I think in Wang Chengrong's heart, he must have thought that Chen Zhitai was hopeless, but from when Chen Zhitai, who later became Wen Jike, seemed to have discovered some secrets, and he would do everything possible to change his face and hide everything and return to Hede Medical College.

At this point, I suddenly realized that all seemingly unrelated things are connected, and what connects them is the passage to Hades.

Chen Zhitai did not hesitate to spend his life incognito to get close to the rumored basement, pretending to be deaf and dumb for thirty years and refusing to leave, what was supporting him to do this, did he really see the mysterious nineteenth step, where his wish to reunite with He Xiaoyu could be fulfilled?

Later, Wang Chengrong told us very regretfully, after graduation, he completely lost contact with Chen Zhitai, and the photos we brought him were the first time he saw his classmates and friends after more than 30 years, and we didn't tell him about Chen Zhitai when we left, maybe sometimes memories are used to remember, I think in Wang Chengrong's heart, he would rather accept a Chen Zhitai who will never meet again, and it is better than knowing that his friend has become a murderer.

When I returned to Hede Medical College, I began to reorganize the process of Chen Zhitai's case, before we always thought that An Rongyue controlled Chen Zhitai to kill people, but I never expected Chen Zhitai to appear in the basement ward for a reason, I wanted to know too much about his purpose and the reason why he could support him to stay after pretending to be deaf and dumb for more than 30 years.

I remember that Chen Zhitai also told Yun Duruo and me before he died that the nineteenth step really existed, and we didn't care about it at the time, but now that I start to think about it, I began to slowly question the rumors about the passage of the underworld and the nineteenth step.

If there really is a passage to the underworld and the mysterious nineteenth step, where would it be?
