Datang: An eight-year-old master of the bar, he gave everyone a blow at the beginning

Chapter 503 Wu Meiniang successfully developed penicillin
Li Er looked condescendingly at Yuchihuan, and said, "Little Yuchi, don't you even have the means to grow lychees and longan in Guanzhong?"

Yu Chihuan nodded affirmatively and said, "Your Majesty, lychee and longan are tropical fruits. It snows and freezes in Guanzhong every autumn, so of course lychee and longan cannot survive!"

Li Er disappointed: "It's a pity, I still wanted to plant lychees in Guanzhong!"

"Your Majesty, the place near the south of Shannan Road is suitable for growing longan!"

Yuchi Huan thought for a moment and immediately recommended a place for Li Er to plant longan!
Li Er waved his hand and said, "Shannan Road is difficult to travel. If I want to eat longan, I might as well transport longan and lychee from Lingnan Road!"

"Your Majesty is wise!"

Yuchihuan secretly heaved a sigh of relief.

Li Er finally gave up after that, he waved his hand and said: "Li Jing, Xiao Yuchi, if you have nothing to do, you can step back!"

"The minister obeys the order!"

Yuchihuan and Li Jing immediately returned to their original positions.

Next, Li Er discussed the state affairs and people's livelihood of the Tang Dynasty with the civil and military officials.

According to Li Er's will, Liu Zhenghui, Minister of the Ministry of Household Affairs, sent a letter to Lingnan Road and Shannan Road and other counties yesterday to open warehouses for disaster relief!
Now the people in the south of the Yangtze River have received relief food from the imperial court.

The people regard food as their heaven, and the common people will not rebel if they are full!

This also allows Li Er to sit back and relax!

Li Er is very satisfied with Liu Zhenghui's execution.

An hour later, Li Er announced his resignation!
The civil and military officials then left the Xuanzheng Hall in an orderly manner and returned to the three provinces and six ministries for duty.

When Yu Chihuan left Xuanzheng Hall, Wei Zheng approached deliberately.

Walking out of the entrance of the Xuanzheng Hall, Wei Zheng followed closely behind Yuchihuan!
The eldest Sun Shunde didn't want to stay with Wei Zheng, so he immediately fled with the officials of Zhongshu Province!

Wei Zheng was known for his uprightness in the Tang Dynasty!

Changsun Shunde, an old guy who is greedy for money and lustful, was impeached by Wei Zheng for a long time!

Fortunately, Li Erkan didn't dismiss Changsun Shunde for the sake of Empress Changsun!
Otherwise, Changsun Shunde would have been exiled outside the customs.

This made Changsun Shunde keep a respectful distance from Wei Zheng.

As for Wei Zheng's revenge on Liangxiu Qingfeng, Changsun Shunde had never even thought about it!
"Wei Zheng, do you need me?"

Yu Chihuan was very uncomfortable being followed by Wei Zheng, so he had to stop and ask him.

Wei Zheng smiled happily and said, "Young Prime Minister Yuchi, the Yunnan Baiyao you gave me has been used up. Can you send me another box of Yunnan Baiyao?"

"Wei Zheng, why did you use up a box of Yunnan Baiyao so quickly?"

Yu Chihuan was dumbfounded, even if Su Dingfang fought in Mobei, a box of Yunnan Baiyao could be used for a year and a half!
Except when Wei Zheng was beaten by Yuchi Huan, he used Yunnan Baiyao to heal his injuries!
At other times, Wei Zheng basically had no chance to use Yunnan Baiyao!
Wei Zheng sighed and said: "Young Prime Minister Yuchi, I inspected Chang'an Chengfang City yesterday and found that many civilians who helped people carry things in the East City and West City had external injuries, so I used Yunnan Baiyao to treat their injuries!"

After finishing speaking, Wei Zheng immediately took out the empty Yunnan Baiyao box and showed it to Yu Chihuan.

Yu Chihuan was speechless and said: "Wei Zheng, I never thought you were an enthusiastic person!"

Wei Zheng nodded and said, "Little Chancellor Yuchi, I don't want the common people to suffer, so I share Yunnan Baiyao to treat their trauma!"

Yu Chihuan thought for a while, and said solemnly: "Wei Zheng, I'm not a hard-hearted person either. Since you don't leave your name behind when you do good deeds, then I will help you!"

After finishing speaking, Yu Chihuan immediately took out two boxes of Yunnan Baiyao from the system space and handed them to Wei Zheng!

Wei Zheng took the two boxes of Yunnan Baiyao and said with a cheerful smile: "Thank you, Prime Minister Yuchi, for your kindness!"

Yu Chihuan patted Wei Zheng's shoulder and said, "Wei Zheng, if there's nothing else, I'll go to Zhongshu Province to be on duty first!"

"Little Chancellor Yuchi, the old man is fine!"

Wei Zheng answered Yuchihuan with a smile on his face.

"I'm leaving!"

Yu Chihuan immediately turned around and headed for Zhongshu Province.

In a moment, Yuchi Huan's figure disappeared from Wei Zheng's eyes.

Wei Zheng hid two boxes of Yunnan Baiyao, and said regretfully, "Yuchihuan is not a bad person, but he is a bit mischievous. If he doesn't beat people up, he will be perfect!"

The next moment, Wei Zheng also returned to Yushitai contentedly.

……

The Ministry of Industry will be the supervisor!
In the morning, Wu Meiniang came to the supervisor full of expectations for her internship.

When Wu Meiniang took out the glass bottle of cultured penicillin, she was shocked by the bacteria accumulated in the glass bottle!
"Why did these bacteria grow all over the glass bottle in just one night?"

Wu Meiniang was startled, she didn't know if it was a good thing or a bad thing!

"Forget it, I'll try the medicine according to the teacher's instructions!"

Wu Meiniang then opened the glass bottle and scooped out some strains for the mice next to her to eat!
If the mouse does not die after eating these bacteria, it means that these bacteria do not have toxins!
As expected by Wu Meiniang, these mice not only did not die after eating the bacteria, but became more lively and active.

Next, Wu Meiniang took these strains and fed them to some injured mice.

If the wounds of the mice were not inflamed after eating the bacteria, then the penicillin culture bacteria developed by Wu Meiniang would be complete.

Wu Meiniang then arranged some injured mice to serve as references!
At noon, Wu Meiniang found that the wounds of the mice that had eaten the strains had begun to scab.

And the wounds of the mice that hadn't eaten the bacteria were still scarlet!
"Haha... It seems that the penicillin culture I developed works well!"

Surprised and delighted, Wu Meiniang immediately went to Zhongshu Province with the glass bottle for the experiment to announce the good news to Yuchihuan.

And a few mice for experiments were also taken away by Wu Meiniang!

……

At noon, it was time for all civil and military officials to go on duty.

Yuchihuan packed up the four treasures of the study, ready to go home for dinner!
As a result, the door was blocked by the dusty Wu Meiniang.

Yu Chihuan was taken aback, and said, "Meiniang, why are you running so fast?"

"Teacher, the students are afraid that you will go home from duty, so they ran to find you!"

After Wu Meiniang finished speaking, she raised the mouse and the glass bottle in her hand!

Yu Chihuan saw the penicillin strain in the glass bottle, and immediately said happily: "Meiniang, it seems that you have successfully developed the penicillin!"

"Teacher, you are right, the students discovered that these penicillin cultures can cure mice!"

Wu Meiniang pointed to the mouse whose wound had scabbed and explained to Yuchihuan!

"Meiniang, you have the penicillin raw material I gave you in your glass bottle. It's normal for the mice to recover after eating the penicillin culture in it!"

Yu Chihuan thought about it, and felt that there was nothing magical about this matter.

Because Wu Meiniang poured ten pills of penicillin produced by the system into a glass bottle for an experiment this time!
These ten penicillin pills are enough to cure ten adults!

Just a few white mice don't need so much penicillin!

"Ah... Teacher, the students think what you said is very reasonable!"

Wu Meiniang was also confused, she didn't know whether the scab on the mouse's wound was due to Yuchicycline or the fermentation strain!
