As soon as she mentioned her son, Empress Changsun immediately cheered up. Li Chengqian is the crown prince. And her son. Of course, he hopes that his son will be a big help when he ascends the throne in the future.

"Then why don't you arrange Li Shen to Gao Ming's side. After a long time of contact, there will be feelings. After all, they are brothers," the eldest grandson queen suggested

"It's useless, Li Shen is still young. I can't see anything in the future. And he indicated that if he didn't argue, he would naturally not join it. Li Shimin said

"Jiro. Gao Ming has always been very good. Empress Eldest Sun said softly. It means that Li Chengqian is very good. Let Li Shimin not have the idea of easy storage. Because recently she found out. Li Shimin spoiled Li Tai a little too much. made Li Tai move his thoughts that he shouldn't have. Empress Eldest Sun also talked to Li Tai about letting him keep to himself and concentrate on his studies. But now it doesn't seem to be working well. They are all biological sons. Naturally, we don't want to see fratricide.

"Don't worry. I know that Gao Ming has been doing a good job. But there is still a lack of tempering. Li Shimin responded. In fact, Li Chengqian has been highly evaluated in history. Participated in politics at the age of 12 and was imprisoned at the age of 14. It's just that Li Chengqian is now sixteen years old. A rebellious period begins. It's already a little bit of a sign of going bad. That's why Li Shimin said that Li Chengqian lacked tempering.

-------------------------------------

It's been more than a month since he was last impeached. Li Shen has not changed much in this month. No one bothered him either. It's still a two-point-one-line life. To say that in this month, the biggest thing Li Shen did was to make tables and chairs for Li Shimin. The last time Wang De gave Li Shen 500 habitual money, he told Li Shen. Li Shimin asked him to make several sets of tables and chairs for Li Shimin. The places where he works are the Liangyi Palace, the Ganlu Palace, the Chengtian Palace, and even the Lizheng Hall of the Empress Changsun.

Li Shen took over this big job, in addition to going to the Guozijian, that is, to go to the division room. made tables and chairs for the emperor, the quality is different from Li Shen's. All of Li Shimin's office desks and chairs are customized according to Li Shimin's height and leg length habits. When measuring Li Shimin's height.

At the beginning, let Wang De come, but Wang De didn't dare, and then let the guards lead Li Anlai, and Li An knelt. To measure the height of the emperor, you have to stand taller than the emperor. This is the sin of the Passover. If you don't get impeached, you will be killed. In the end, in order to measure Li Shimin's height, Li Shen had no choice but to ask for the magic weapon Empress Changsun to complete the task.

In terms of materials, they are all good red sandalwood, and because they are made of dragon chairs. This brings us to engraving. Li An borrowed two master carvers from the Ministry of Industry. Specialized in engraving. Dozens of craftsmen were dispatched, and it took seven days to complete the work. It is mainly time-consuming to carve the back of the dragon chair.

And it is as smooth as a mirror when polished inch by inch. Let Li Shen sigh. Who said that the ancients couldn't make high-quality products if they were backward. It depends on who does it.

In addition to making tables and chairs for Li Shimin, Li Shen's life is as calm as water. Li Shen also enjoys the life of no one to disturb him. But just when Li Shen didn't enjoy it for long. A major incident happened, and Li Yuan was critically ill.

Li Yuan was the founding emperor of the Tang Dynasty, and later after the Xuanwumen incident. was forced to give way to Li Shimin. In his later years, he lived in Da'an Palace. Zhenguan suffered from wind disease for eight years. As a grandson, Li Shen also visited. Li Shen felt that it was a stroke. Now critically ill. All the royal relatives and nobles, don't care if they are sincere or not, they have to go. Li Shen is no exception. So all the princes and princesses followed Li Shimin to Da'an Palace that day. In the vertical arch hall, everyone saw Li Yuan, who was already dying. The founding emperor of the Tang Dynasty has now run out of oil. Li Shimin stepped forward and called Li Yuan lightly. Li Yuan barely opened his eyes. Li Shimin said softly:

"Aya, your sons and your grandchildren have come to see you."

Li Yuan tilted his head and glanced at many children and grandchildren, then looked at Li Shimin, raised his hand slightly, Li Shimin understood, and quickly grabbed Li Yuan's hand. Closer to some. It is convenient for Li Yuan to speak clearly.

Li Shen is at the back. He didn't hear what Li Yuan said to Li Shimin specifically. I saw Li Shimin nodding in response. After a while, Li Yuan closed his eyes, and let go of Li Shimin's hand weakly. Li Shimin slowly stood up and nodded to Wang De beside him. Wang De understood: Walk to the front of the palace. said loudly: "Emperor Taishang~~~~ collapsed ~~~~~~~"

Then the princes and princesses fell to their knees. Shouting Grandpa Li Yuanhuang. Li Shen is one of them. Li Shen could see it. Li Shimin is really sad. If you want to say who doesn't want Li Yuan to die the most. That must be Li Shimin. Li Shimin has always wanted to prove that Li Yuan was wrong at the beginning, and he was right. In the past few years, he has worked hard, and part of the reason is that he wants to prove to Li Yuan how good he is. But now Li Yuan is gone. Li Shimin's heart was empty. And the eldest grandson queen had already lost her voice and cried bitterly. Li Yuan is very fond of Empress Changsun. At the beginning, it was Li Yuan who personally elected such a family affair for Li Shimin.

The death of the Emperor Taishang requires a lot of work. Because it takes a long time to remain in the mortuary, it is necessary to dispose of the body by a special person. Choose a mausoleum, set up a mourning hall, arrange the body, and prepare a crown. Because it's a national funeral. Many surrounding countries want to shoot envoys to come to Chang'an to offer condolences. Li Shen's grandchildren also have to arrange to go to the vigil.

Li Shimin proposed that Li Yuanmiao was called Gaozu and Emperor Taiwu. National mourning. Envoys from various countries entered the palace to mourn, and Li Shen was arranged to hold more than a dozen wakes before and after. Until October. Li Shimin decreed. Li Yuan was buried in the Xian Mausoleum, 80 miles away from Chang'an. He was buried here with Li Shimin's mother, Queen Taimu, Dou.

Up to four months passed. Li Shen finally began to live a peaceful life again. It's just that Li Yuan's death touched Li Shen a lot. It's not that Li Shen is so sad. The common feelings of birth, old age, sickness and death. Li Yuan is over 70 years old, and this era can be regarded as a joy and mourning. Li Shen was thinking about what to do if Waiyi was sick. In this era, a cold is easy to make people die. He remembered that in ancient times, typhoid fever was the most common death, and external evil entered the body. It's actually an infection.

Because of Li Yuan's death. Li Shen needs Ding Wei to keep filial piety for three years. In fact, up to 27 months. Like Li Shimin, he went to the court to work in 100 days. And Li Shen has to be at home for a year. Most of the princes and princesses were. Except for people like the crown prince, or the king of Wei, the emperor can find an excuse to come out on the grounds of doing things.

Li Shen has been thinking about life, old age, sickness and death since he thought about it. It's not very stable. Li Shen also felt that he was a little small-eyed and afraid of death. But it just lingers. So he took advantage of Ding Wei's home. Spend all day meditating on the solution.

After thinking about it for half a month. Finally reminded him of a Japanese drama he had watched, which contained a detailed method of extracting penicillin at that time. Later, he also searched the Internet for this to be feasible.

In fact, the materials used in TV are not difficult to find. Rice flour and taro juice are used as a nutrient solution. The mold is peeled off with the green hair of the steamed bread. And carbon is even better to find. What's missing is something to filter. However, spun yarn can be used. Put a few more layers. I can make do with it, too. The only drawback is that the concentration is not known. It is also said in the TV series that it can be purified repeatedly to increase the concentration. So Li Shen began to prepare.

Early penicillins were also found from molds. Li Shen is not an expert and professor, he can only experiment according to the method, as long as there is time, he will definitely succeed. So it began in November of the ninth year of Zhenguan. Li Shen embarked on the path of his scientific madman, during which time he was in addition to the news that the army that had defeated Tuyuhun had returned to the dynasty. There is no important news. No one, including Li Shimin, is paying attention to Li Shen. Li Shen was relieved to face all kinds of moldy substances, with a sour smell.

Late December. When the New Year comes, there is a banquet in the palace as usual. Li Shen was personally invited by Wang De. Because no one else can see Li Shen.

"Lord Wang, I can be regarded as finding you. Your Majesty asked you to go to the Lin De Hall for a banquet. Today's arrivals are all officials and their families above the fifth grade. You're going to participate in it too. Wang De said with a headache.

"Lao Wang. Do you think I can not go? Didn't it mean that Ding Wei Shouxiao didn't participate in entertainment activities? Li Shen said reluctantly. Since the last time he sent money to Li Shen, Li Shen felt that this eunuch beside Li Shimin was very good. Nor arrogant. Therefore, Li Shen was called Wang De Lao Wang when he met him. Wang De felt quite close and did not object. Li Shen hasn't been out of the palace for almost two months. No less than 100 penicillin samples were produced, none of which were successful. It seems that you can't just know the steps. In the novel, you can make penicillin when you cross over, how do you do it?

"Oh, my lord. It's not much entertainment, don't talk nonsense. This is the usual practice, an acknowledgment of the hard work of the ministers. Don't embarrass the old slave. Wang De hurriedly said

"Okay, okay, I'll wash up and change my clothes later," said Li Shen and walked towards the dormitory

Note, please watch the Japanese time travel drama. Benevolent doctors. It contains the specific method of penicillin extraction and purification method. Much the same approach to the German front during World War II. The author searched on the Internet. There are Xueba Internet celebrities who have done it according to the method, and it is indeed possible. It's just that the number of penicillin bacteria is a little less. It takes half a month to raise 1 person's portion. The best medium is corn paste. So forget it. Another broke the news. In Germany, in the absence of medicine, penicillin bacteria were extracted from the urine of the wounded who had been injected with penicillin. It is also doable.
