"What's your name?" Wang Bing was surprised.

"Yu Haohua!"

Wang Bing couldn't speak for a long time to confirm the child's name.

Yu Haohua? He has the same name as Mr. Yu.

"Should not..." Wang Bing thought of a possibility. Is this child Yu Haohua in his childhood?

Yu Haohua suddenly remembered what he had told him about the friend who taught him medicine when he was young. At that time, he said that it was more than 60 years ago. Although things have changed and his impression has been a little vague, he felt that Wang Bing was a little familiar at the first sight when he saw him.

So it's not unreasonable to look familiar, because the person who taught Yu Haohua's medical skills was Wang Bing himself.

Combined with what Mr. Yu said and the child's life experience from the shop assistant, it can be determined that the child in front of him is Yu Haohua when he was a child. He can't be wrong.

So Wang Bing went through and met Yu Haohua, who was just a child more than 60 years ago, and now he has accepted him as an apprentice.

"It turned out that I was the one who taught Mr. Yu medical skills for a long time!" Wang Bing grinned, but immediately thought of a problem, he is now back to Yu Haohua when he was a child, but in his own time line, Yu Haohua has been killed, so who is going to teach Yu Haohua's medical skills on that time line?

Wang Bing has analyzed the problem of "time line" and "time point" before. Each "time line" is a brand new life. Now he comes to Yu Haohua's childhood. When Yu Haohua is old, Yu Haohua will meet him again, but he should not be who he is now, but who he will be later If so, where are you now?

It's a real headache!

"Teacher..." Xiao Yu Haohua's cry brought Wang Bing back to reality.

"Don't call me a teacher. If you want to see me, it's fate. We are friends. Just call me" friend. " Wang Bing did not dare to tell Xiao Yu Haohua his name.

"Friends? No good? "

"I said yes, I will teach you medicine tomorrow!"

"Good!" Little Yu Haohua smiles happily.

Late at night, little Yu Haohua had already fallen asleep, but Wang Bing did not feel sleepy. He went back more than 60 years ago by accident. Now how can he go back to the original "time line"?

He certainly can't stay here for 60 years. What's the world like after 60 years?

But now what?

Wang Bing can only reverse the flow of time, but can't make time advance.

He fell into a deep meditation. Since time can go back, surely it can go forward, right?

If this conjecture holds, Wang Bing will be able to return to the original time line.

So how can we make time go forward?

In the next month, Wang Bing was instructing Yu Haohua's medical skills while thinking about the way to return to the original "timeline.".

Yu Haohua's talent in medicine is quite high. Wang Bing knows a lot of things as soon as he talks about them. He pesters Wang Bing to teach him more every day. So Wang Bing compiles a Book of his medical skills and gives it to him. The little guy is in a state of forgetting to eat and sleep.

"Teacher, what needle did you put on me that day?" One day, little Yu Haohua asked.

"That's a cure!"

"Can I learn?" He asked expectantly.

"Let's talk about what I taught you first!"

Little Yu Haohua was a little disappointed after listening.

"Learning things step by step, step by step. The so-called desire for speed is not enough. Only when you can learn what I have taught you can you learn more. Learning too much is not good for you!" Wang Bing explained.

"I see, teacher!" Little Yu Haohua is also an open-minded person.

"Here you are!" Then Wang Bing took out a wooden box from his body, which contained some acupuncture needles that Wang Bing had used when he had just learned "heaven and earth acupuncture".

"Thank you, teacher!" Xiaoyu Haohua is very happy. Although he has not yet learned acupuncture, his child is easily satisfied.

"Well?" Jubilant look at the as like as two peas, Wang Bing remembered something. Yu Haohua had shown him the acupuncture needle from his friend. Now he thinks of it exactly the same as he gave to Xiao Yu Haohua.

"I gave that box to Mr. Yu!"

It was Wang Bing who gave the needle to little Yu Haohua that made Wang Bing know the story of Yu and his "friend" when he saw the needle.

Three months later, under the guidance of Wang Bing, little Yu Haohua made great progress. He learned a lot every day. Wang Bing would test him every day to test his learning achievements. According to Wang Bing, this boy can be expected in the future. No wonder he will become a leader in the world's medical field. His talent in this field is really high. If you can take Wang Bing as an example, he will become a leader in the world's medical field He has learned all the skills of a soldier, and his achievements are limitless. He will definitely surpass Mr. Yu.It was another sleepless night, and Wang Bing was thinking hard about the way to return to the original "time line". He had been thinking about it for three or four months, but he still didn't move forward.

Let time forward, should be a reverse process of time?

So how can the opposite process be realized?

Because he was afraid that he would inadvertently let time flow back again, Wang Bing did not dare to use the ability of time flow back to do experiments. He thought about countless possible theories, but which one is practical?

Lying on the bed, Wang Bing's head was full of thoughts. "Could it be that I thought things too complicated?"

When time flows backward, the visualized time begins to flow

"Flow?" In a trance, Wang Bing seems to have caught something.

"If those lights and shadows are the manifestation of the flow of time..." There is a feeling in my heart that is more and more clear. It seems that there is something Wang Bing has not noticed. That is, the light and shadow flow in a certain direction when "time goes back". To be exact, it flows in the direction of Wang Bing's left hand side.

Yes, "time reversal" always flows in the left-hand direction, no matter fast or slow, no matter long or short. This feature has not changed from the beginning.

"Is If you move to the left, it means "time reversal"? So if it's going to the right Can we move time forward? "

This conjecture made Wang Bing happy. Why didn't he think of it before?

But whether speculation can be realized or not, and whether time can advance, is a question?

Unable to bear the excitement in his heart, Wang Bing said that he would do as soon as he could. His mind moved, and familiar light and shadow appeared around him
