When he came out of the Cheng Mansion, Li Yuanjing knew the result, and there was a high probability that he would not be able to see the two brothers of the Cheng family in half a month or a month.

If you count the previous ones, we haven't seen each other for almost two months.

After such a long interval for the first time, Li Yuanjing also felt a little empty in his heart.

Back at the palace, Li Yuanjing directly asked people to cook the steak in iron plate, iron mesh charcoal and other methods in accordance with the latest operating specifications, and finally satisfied the mouth.

The only regret is that there are no tomatoes, so I can't make black pepper juice, and the steak always feels weird to eat.

Wang Xiaoyi was nibbling on the steak brought back by Li Yuanjing, while his resentful little eyes kept looking at Li Yuanjing.

Li Yuanjing had no choice but to silently remind himself in his heart, the young man didn't know what was expensive, and what was the old man?

Before the steak was finished, Li Yuanjing sacrificed the Great Escape Technique to escape, and having opened meat does not mean that he can't control himself, Li Yuanjing still feels that he has no problem with self-control.

The next few days can be regarded as peaceful, and the big families are quite quiet, I don't know what is bad.

Three excavators have already been built, and because they are so large that even if the wheels are installed, they still need to mobilize ten oxen to barely pull them, which is still the result of using wheels instead of crawlers.

The construction of the base camp of Qianzhuang has started, and the speed is naturally much faster than that of manual labor, but problems have also arisen.

The effect is far from being as good as Li Yuanjing imagined, the biggest problem is that the lower you dig, the less soil can be dug out, and the mechanical arm composed of gears seems to have some defects in this regard, but it is better than nothing, at least Li Yang's house is no longer shouting for people, and keeps running to Li Yuanjing to ask for a new excavator, saying that he will give him twenty units, and he will be able to dig the pit before the winter in two months at most.

Excavators also need to be manufactured one by one, and at the same time, research and improvement are carried out according to the problems that arise, and the initial speed is naturally not fast.

After these machines dug the pit of Qianzhuang, they had to be transferred to dig an artificial river, but Li Yuanjing's real estate plan has never been put down.

The imperial court is fully preparing for war against the Turks, and it is also very busy in this regard.

The military offices began to assemble and prepare, which belonged to the form of pre-war training, and after the order of the imperial court was issued, they would assemble and start to fight.

Li Jing was officially appointed as the general manager of the Dingxiang Road march, and coordinated the Northern Expedition to the Turks.

In September, Huazhou Thorn Shi Chai Shao was appointed as the chief of the Shengzhou Road March, and in November, Li Ji, the governor of the prefecture, was appointed as the head of the Tongmo Road March, and the Huazhou Thorn Shi Chai Shao was reappointed as the head of the Jinhe Road March, and Li Daozong, the king of Chengjun County, was appointed as the head of the Datong Road March, and the Youzhou Governor Wei Xiaojie was appointed as the head of the Heng'an Road March, and Xue Wanshu, the governor of Yingzhou, was the head of the Changwu Road March.

A series of appointments were released at the same time on the same day, and the generals involved went to their respective territories to prepare for deployment, and the soldiers of the Tang Dynasty, who had assembled for several rounds and completed several trainings, also regrouped again, this time they did not let people go after twenty days of training as before, but immediately rushed to the camp to which they belonged after the personnel were in order.

The Tang army fought a war when countless military governments formed an army, an army of about 20,000 people, and before the appointment of the imperial court was issued, no one knew which army they were in and which general would be under them.

However, these have long been strange to the soldiers of the old mansion, and Datang has always operated like this.

"How have you been doing with Chu Mo and Chu Liang lately?" It was a little cold in Chang'an in November, and Li Yuanjing asked people to come back from next door with some coke, and several people sat in a circle in the courtyard and roasted the fire.

After all, the base camp of Qianzhuang was still not completed, and the construction of the excavator was too slow, and the work was stopped in winter.

And those excavators were directly pulled to work in the mine by the eldest grandson Wuji, anyway, the winter has little impact on them, and they can also test the results.

Unlike Li Yuanjing's guess, from August to now, three months have passed, and there is still no news from the two brothers of the Cheng family.

The others made a perfect comeback last month, and they couldn't see what it looked like they had been in bed for a month or two because they were beaten.

"I don't know what's wrong with the two of them, anyway, I heard that when they are about to get better, his father will beat them up and let them continue to lie down for ten days and half a month." Fang Yiai smiled, shivering all over.

Fortunately, I was witty, and I ran out before I could get better, otherwise I am afraid that it would be similar to the fate of the two of them.

However, before the mood was beautiful for two seconds, Fang Yiai's good mood instantly fell to the bottom, and he asked with a sad face: "Your Highness, when will you be able to solve my problem?" I tried it again last month and it felt slightly better than before, but still ......"

"Don't worry, you have to test it on someone else first, don't you? You don't want uncontrollable results, do you? Li Yuanjing comforted the widow of the sentence without hesitation.

Penicillin has been studied by soil method, and the research process is very bitter, and the process of testing is even more bitter.

What is the principle is still very difficult for Li Yuanjing, the scum, anyway, it is to pour the prepared penicillin into the cup, and then use a cotton swab to dip some urine in the center of the cup and hang it in the center, after seven days, if there is no penicillium in the center, only in the center, then it means that it is successful.

As for whether it can be effective on people, this is not clear, anyway, it has to be tested, and Li Yuanjing has already found a target.

"Your Highness, you don't want to experiment with me, do you?" Fang Yiai's little eyes kept turning, looking Li Yuanjing up and down, how to think about it and feel that something was not right.

"Huh?"

"Yes, it must be so!" The more Fang Yiai thought about it, the more she felt that this was the case, and said a little crazy: "You have already done that, and you are still with us every day, although I can't do it, but after experiencing it, I still want it very much, why aren't you in a hurry at all?" You must be like me, you want to experiment with me, and you can ......make it yourself when I get better."

"......" Li Yuanjing is full of black lines on his forehead, what is the special meow, Lao Tzu is not good like you? The golden gun doesn't fall to the little macho to understand?

Who said that this king is not in a hurry? This king just thinks that he is still young now, and it is not a good thing for himself and Wang Xiaoyi, it will be too late, endure it for a few years now, and it will be extended for more years in the future, and such a simple arithmetic problem will not be?

"This king is too lazy to explain to you!"

"You must be the same ...... as me" The expression on Fang Yiai's face became more and more shocked, and was immediately replaced by a smile on his face, and he said excitedly: "Fellow believers!" Fellow travelers! My heart is finally no longer bitter, no longer bitter......"

Li Yuanjing was about to rub his love on the ground fiercely, but in a blink of an eye, he saw several familiar figures, especially the two brothers of the Cheng family who had a blue nose and swollen face, and they were very happy to walk with a limp.

But at this moment, Li Yuanjing cares more about another person!

"Du Er, your father's illness has healed?"
