Bai Yiyuan finally got a limited recognition, he actually understood some things about Corey, but he was not interested in these, anyway, Lu Xiaohu had already agreed, and he could put it into practice immediately. So after he came out of the director's office, he hurried back to himself, wanting to find Xiao Ping to deal with some details of the third recorder together, and then use it for patients who came to see the doctor.

He walked to his office, not paying attention to the movement in front of him, and bumped headfirst into a man who was wandering around at the time, so he didn't see it. The two of them were rear-ended, and the unintentional collision was the worst, Bai Yiyuan was hit in the ribs, and instantly felt a little stuffy in his chest, and that person was knocked forward and staggered a few steps forward, leaning against the door of Bai Yiyuan's office before barely stopping.

Xu Jingnan was taken aback, and hurriedly went over to ask, "Sister Zichen, are you okay?"

Liu Zichen's knee was on the door, fortunately this door is not an iron door, otherwise it would have to be bruised, mainly because he stood well and was startled, "It's okay, who is this, walking so fast?"

Bai Yiyuan stabilized his body, he was surprised to find that he had bumped into a girl, he was quite embarrassed, it was indeed caused by not looking at the road, but he also saw Xu Jingnan next to Liu Zichen, they had already met and knew each other.

"Doctor Bai, it's you!" Xu Jingnan came over to greet with a smile, "Such a coincidence, you must have known that we were waiting for you here, so you rushed back in such a hurry, right?"

"Haha, Doctor Xiao Xu is really humorous, it's all because I'm old and my eyes are not good, so I didn't hurt her, right?" Bai Yiyuan asked embarrassedly rubbing his chest.

"It doesn't matter, it's just a little accident. Liu Zichen figured out Bai Yiyuan's identity and immediately returned to normalcy.

Bai Yiyuan knew that they must have come to find him because of something, so he directly led Xu Jingnan and Liu Zichen in, strangely enough, the assistant Xiao Ping was not there, no wonder others came to the door but didn't come in.

Bai Yiyuan personally poured two glasses of water, wiped the sweat on his forehead, and hurriedly argued with Lu Xiaohu for a while, just sat down, Bai Yiyuan sweated and the heat rose.

"Two detectives, is there anything else to do with me today?" Bai Yiyuan asked after a pause.

"Oh, yes, we're here to ask you about a patient of yours. Liu Zichen said truthfully.

"My patient?" Bai Yiyuan continued to ask.

"That's right, maybe four or five years ago, it's been a long time, but his son said you were his teacher, so I guess Dr. Bai should remember him. Liu Zichen deliberately sold a small pass, and he also wanted to be Guo Wei's words from the side.

Bai Yiyuan frowned, and looked a little thoughtful at first, but when Liu Zichen mentioned that he was that person's teacher, he immediately reacted, "You are talking about Guo Wei's father Guo Ke! That's true, Guo Ke is my patient, until he died, I was doing psychological counseling for him, but it's a pity that ......"

Liu Zichen nodded, "We all know that you must have done your best, but I heard Guo Wei say that his father had been examined and treated by you before he was diagnosed with cancer, can you still remember the situation at that time?"

For Bai Yiyuan, he has received countless patients, not to mention a few years ago, and many details must have been forgotten. But Guo Ke is indeed a very special patient, not only because he predicted the occurrence of cancer for the first time, but also because this person is also the father of his current beloved apprentice Guo Wei, so he can still remember some of it.

In fact, even if Guo Wei did not learn from him later, he would have engraved the name Guo Ke into it, because Zheng Jun, who died this time, and Guo Ke back then, were both detected by him to have cancer cells, and the situation was similar. The difference is that the current situation of Zheng Jun and Chen Qian is basically under Bai Yiyuan's control, but it can't be accepted, and five years ago, Guo Ke's test results even Bai Yiyuan himself couldn't believe it.

At that time, Guo Ke's school infirmary carried out psychological activities, and Bai Yiyuan, as an invited expert, conducted psychological counseling for some students in the school, and Guo Ke, as a teacher, just took the students to participate. Bai Yiyuan remembered that Guo Ke's hair and beard were very thick and dense, at best it was like studying academics, at worst it was a little sloppy and not good at repairing, and the first impression was that this person was almost fifty years old and had a heavy heart, which made the careful and professional Bai Yiyuan look at it. After tutoring the students, Bai Yiyuan deliberately left Guo Ke to communicate with him, and he knew that Guo Ke had been busy for several months in order to work hard to conduct research to find a job, and his body and spirit had reached a limit. Out of kindness, Bai Yiyuan performed a hypnotherapy treatment for Guo Ke, the effect was still good, and his condition really improved, so Guo Ke was very grateful, and later cooperated with Bai Yiyuan to use the three-recorder that had just left the factory at that time for monitoring.

It was really the first time that the Sanlu instrument was used in practice, and even Bai Yiyuan was not sure how effective it was, it was just a test at that time, and it was not as sure as it is now. As a result, it didn't take long for about a month, Bai Yiyuan found that there were a very small amount of cancer cells in Guo Ke's body in the feedback data of the three recorders, which was not a small surprise, he immediately contacted Guo Ke, Guo Ke was suspicious, because there was indeed a tumor in his body, but it was determined to be benign, but such a thing was really serious, so Guo Ke immediately went to the hospital for examination, and there was no problem.

In view of Bai Yiyuan's help to him in the past, and this matter was just a favor for others, Guo Ke did not care too much about this kind of thing, but encouraged Bai Yiyuan to continue research, just like academics, failure is the mother of success.

The first use of the three-recorder ended in the detection error, Bai Yiyuan was very lonely, but as Guo Ke said, he continued to devote himself to the improvement of the three-recorder with greater enthusiasm and efforts. In the following days, Bai Yiyuan used himself as a link, kept testing, and gradually determined that the data of the three recorders was basically the same as the actual situation, and the predictability was confirmed again. However, the hospital did not agree and the patients did not recognize, which made Bai Yiyuan's invention difficult, and without the support of cases, nothing could prove its effect, especially the failure of Guo Ke's test, so that the department has always refused to agree with Bai Yiyuan to put private research into the hospital's treatment and examination.

Later, Beiting already understood, and about half a year after the third recorder detected that Guo Ke had cancer cells in his body, Guo Ke's body took a sharp turn for the worse, and he came to the hospital again for a re-examination. This incident must be a disaster for the Guo family, but it is very exciting for Bai Yiyuan, after all, it can show that the foresight of the Sanlu instrument exists.
