Today is the last weekend before the Spring Festival, and there are three days before Chinese New Year's Eve.

Li Guocheng got up early, and after completing his daily cultivation, he first went to his master Zhang's hometown to help buy the quota of his grandparents and grandchildren.

Now Zhang Zhijing is already working in the rolling mill, because of Li Guocheng's face, Li Huaide takes care of it very much, and directly gives a 12-level clerk position, with a monthly salary of 23 yuan.

Now that Zhang Lao has no worries, he is usually very leisurely, and he goes to Tongrentang to sit down when he has nothing to do, and studies new cases with his senior brother, Li Guocheng directly follows the name of leukemia in later generations.

There are now two similar cases, a 12-year-old girl and a 6-year-old boy. Li Guocheng also accompanied them to their home for an investigation, and found nothing abnormal. The exact cause of the disease has not been found.

In addition to the beginning, Li Guocheng participated in drug monitoring, and the follow-up was treated by Zhao Lao and the senior brother, who wanted to find an efficient and cheap prescription.

When Zhao Lao found Li Guocheng to explain the condition of the two, Li Guocheng was shocked to realize that leukemia did not suddenly appear in later generations, and should have always existed. Because Li Guocheng's energy was focused on the rolling mill, he did not have time to participate in follow-up research, so he informed Zhao Lao of the cause of the disease known to later generations, and told Zhao Lao his understanding of leukemia.

The current Zhao Lao seems to have a second spring, and he has recorded a large number of research notes, as long as he sees Li Guocheng and discusses it.

Today, I came out of Zhao's house, riding on the road, thinking about the little boy's condition. Suddenly I remembered Xiaodouzi, the well-behaved and sensible little girl.

When Li Guocheng went to treat Yuan Lao on the first weekend after he got married, he met Song Lao, and he thought he was waiting for him to help check his granddaughter, but he didn't expect what Song Lao said to make Li Guocheng unbelievable.

Song Lao has obviously aged a lot, and under his narration, Li Guocheng learned that Xiaodouzi's parents learned through relationships that developed countries already knew the cause of leukemia, and had a very effective treatment, what is chemotherapy. Under the bitter begging of the husband and wife, Song Lao could only succumb.

That day, Song Lao came to Li Guocheng to apologize, Li Guocheng relieved Song Lao for a long time, and promised that as long as Xiaodouzi came back and was willing to seek treatment from him, Li Guocheng would never shirk. Looking at Song Lao's relieved appearance, Li Guocheng realized that the main purpose of Song Lao's coming today was self-evident.

In any case, his heart is heartache for the little girl, although he was not a doctor in his previous life, but through developed information, he still knows the pain of chemotherapy, and the cure rate is not high.

Riding a bicycle to Yuan's hometown, Yuan Lao was busy with work and had no time to take care of Li Guocheng. Today is the 4th treatment, and now Yuan Lao's health is getting better and better, eating and sleeping have become normal, and his enthusiasm for work is even more.

Li Guocheng sat on the sofa and took out a semiconductor-related book from his satchel and read it. With the deepening of his studies, Li Guocheng's understanding of semiconductors became more and more thorough, and he had the idea of directly manufacturing chips.

That is, think about it, no matter how fast you run in the future, the foundation must come step by step. He has simulated countless times in his mind, first preparing a single transistor, finding the best ratio according to the test data, and then considering making several special integrated chips, each of which is a fixed logic, and then concentrated on a circuit board to complete the purpose of automatically controlling the operation of the machine tool.

"The circuit board is relatively simple and can be handed over to Zhou Xiaojuan for study. The mechanical design and manufacturing will be handed over to Wang Gong and Master Yi, and I only need to give direction and ideas. In the future, my main focus should be on semiconductors," Li Guocheng thought.

Half an hour later, under the reminder of the assistant, Yuan Lao put down his work.

"Xiao Li, you help me take a look, I seem to be fine", Yuan Lao was full of confidence.

Li Guocheng smiled, took out the pulse pillow, Yuan Lao put his left arm on it, and Li Guocheng carefully perceived. Changed the other hand, all considered.

"Grandpa, judging from the pulse, it is indeed a lot better, but it still needs to be treated a few times, and at the same time, remember to take the health medicine prescribed by Master Zhang."

Yuan Lao was noncommittal, "Do you still have enough ginseng?" If it's not enough, I'll find a little more."

"Grandpa, that's enough, I went to the mountains to change a 30-year-old wild ginseng, the effect is very good, every time I eat a little bit can be recovered", since he knew that Yuan Lao used his own allowance to buy ginseng, Li Guocheng did not have the idea of wool, and every time he prevaricated.

"Grandpa, you lie down on the sofa, I will help you with acupuncture."

"Just take medicine in the future, acupuncture and moxibustion will be enough", Yuan Lao reluctantly lay down on the sofa.

"Don't worry, Old Yuan, I can still easily make up for the consumption caused by your illness, you look at my complexion, I am stronger than anyone else", Li Guocheng understood the old man and hurriedly comforted.

"Also, it's a pity that you don't join the army with this body", Yuan Lao has always complained about Li Guocheng's technical research.

Maybe he was born in the military, but he was still closer to the military. More than ten years have passed, and the old man has also realized the importance of science and technology, otherwise Li Guocheng would have been pulled into their organization.

Through the silver needle, Li Guocheng sensed that Yuan Lao's condition was under control and was improving.

"Grandpa, the treatment effect is good, and the recovery is good, but it still needs treatment, and the medicine can't be stopped."

Li Guocheng deliberately shortened the treatment time, only controlled his face to be pale, and did not dare to sweat profusely and collapse like in the past, as if he was going to die.

In front of Yuan Lao, he took out the 30-year-old mountain ginseng from his shoulder bag, and now only half of it was left, cut off a quarter with a knife, and put it in his mouth. It's not much, you have to save it.

"Grandpa, you have also seen it, now you just need to maintain the effect of the treatment, your own Five Elements system is working well, I don't need to work as hard as in the past."

Yuan Lao looked at Li Guocheng, "The Five Elements Doctrine is feudal superstition, don't say it again in the future."

Li Guocheng also understood what Yuan Lao meant, so he did not refute it.

"Grandpa, do you know how Xiaodouzi is?"

"Lao Song didn't say it, who knows!"

Looking at Yuan Lao's expression, it is estimated that the situation is not very good, just like trying harder.

"Grandpa, the next time you see Song Lao, tell him that if the treatment effect of Xiaodouzi is not good, he still believes me, so take Xiaodouzi back."

Yuan Lao just nodded and did not continue the topic.

"Last time, Lao Zhao Tou talked to me about you, and he was very optimistic about you and asked me to protect you. , you're my grandson-in-law, and you still use him to nag. I've already gotten a gag order with a few of them who know about your situation, so you can listen to that old Zhao Tou in the future and concentrate on technical research."

Listening to Yuan Lao's tone, he was obviously unwilling, but he didn't know why he was persuaded by Zhao Lao.

"A few gadgets you researched earlier, and the trial worked well. In an arrest, the two people who rushed to the front were saved, each of them was shot twice in the chest, and if there was no bulletproof vest, it is estimated that they would be gone. The opponent is a veteran, and he has stronger close-quarters combat power, and he uses his position to force the team members not to shoot, and finally uses a bulletproof shield to compress the opponent in the corner and kill."

Yuan Lao sighed, took a sip of strong tea, and continued: "Just this is how many team members were injured by the other party. Without a bulletproof vest and shield, not only will it not be possible to catch him, but several will be sacrificed. I thank you for them."

Li Guocheng was very happy when he heard that what he designed had played a role.

"In the future, if you have a good idea, you must think about studying more similar things", Yuan Lao seemed to have no intention, but in fact, he was full of expectations in his heart.

"Don't worry, grandpa, I will."
