People in Datang have been expelled from school

Chapter 680

"How do you even know where Wu Mei was born?"

"I……"

Seeing Li Lizhi staring at her, it seemed that something was wrong.

Stopping, Li Zheng said to Li Lizhi: "Did we have some misunderstandings?"

Li Lizhi whispered: "Then do you know when I was born?"

Li Zhenggao said with a deep smile: "In the fourth year of Wude, in March, he was born in the Qin Palace."

Li Lizhi froze in place, did Li Zheng say it so easily?
But after thinking about it carefully, it seems that this matter is not a secret, as both the clan and the court know it.

I feel like I'm asking nonsense.

Maybe Li Zheng really has some unpredictable skills to be able to tell so many things about Wu Mei.

Moreover, Li Zheng never seemed to have looked at Wu Mei more seriously.

He is an unfeminine man.

Thinking of this, Li Lizhi felt relieved a lot. Li Zheng would not be interested in a woman easily.

In other words, for Li Zheng, women are not what he wants.

At home, Li Zheng spends more time reading in the study.

The tricycle has basically replaced the old mode of transportation in the village.

However, the current tricycle is not very durable, and it will break every three days.

Every time it breaks, the three brothers of the Tie family have to repair it.

Back home, Li Lizhi said, "Li Zheng, what you and Yuan Tiangang said offended Wu Mei a bit."

Li Zheng looked at the book in his hand and said, "I didn't say too much."

Li Lizhi was still worried, "Will Wu Mei become estranged from us in the future."

Li Zheng turned a page of the book in his hand and said, "Would the Wu family dare to refuse to say something to you, Princess Changle?"

Li Lizhi glared at Li Zheng again, and walked into the room.

Xu Hui came over with a bowl of tea, "Actually, Her Royal Highness is very concerned about the relationship between her and Wu Mei."

Li Zheng took a sip of tea and said, "I know."

Xu Hui said in a low voice: "When she was in the palace, Princess Changle, as the eldest sister, had to take care of the prince and princess most of the time, and Her Majesty and Queen couldn't take care of her, and she couldn't say that she was always taken care of by those maids and eunuchs. Friends, Princess Changle has very few friends, and Wu Mei is one of the few."

After listening to Xu Hui's words, Li Zheng left the book again.

If you think about it carefully, this is indeed the case.

The children of the royal family were born in the deep palace and grew up in the bad environment of the palace.

Xiao Sizi and Li Zhi are not bad, at least they are in the village now.

Li Zhi can play with his little son, and there are so many children who can play with him.

Now Li Zhi already has many playmates.

Companions are very important in children's childhood.

It also has a great influence on the character development of children.

Royal tutors are indeed a big problem.

Li Zheng continued to look back at the book in his hand, which was an academic report on chemistry in the Middle Ages.

The development of chemistry in the Middle Ages has been very good, and there are many strange records.

Something called mercuric fulminate, a white crystal that medieval chemists discovered worked better than gunpowder.

It is prepared by reacting mercury nitrate with ethanol in excess nitric acid.

The stability is very poor, collisions and needles, and friction can easily cause explosions.

Li Zheng continued to look at these academic reports.

There is a lot of chemical knowledge in it, which is simply the necessary knowledge for traveling at home and killing people.

Poisonous smoke and invisible chemical poisons made by a lot of chemical knowledge.

Li Zheng felt that the medicines in his system pharmacy could indeed extract these chemicals.

Of course, I am just a half-assed chemist.

I don't even know the basics of chemistry.

If you really learn mathematics, physics and chemistry well, you will not be afraid to travel all over the world.

Mercury fulminate is easy to carry, as long as a piece the size of a fingernail can explode into the power of a grenade.

If it is tons of mercury fulminate, this power is no less than some high explosives.

The only downside is that the stability is too poor.

If you can make mercury fulminate, why not make your own grenade?Stable and easy to use.

Most of the books in the current system library are medieval knowledge.

The Middle Ages was an era of scientific inflection.

That era was also the era of the fastest scientific development.

No era produced more scientists than the Middle Ages.

The Middle Ages was also an era of rapid intellectual growth.

People have entered the semi-industrial age from the era of slash-and-burn farming.

Then to the full industrial age, almost all of them were completed in one middle age.

Li Zheng put away the academic report and returned to his study.

Start taking notes.

In the morning of the second day, Li Zheng slept until dawn and practiced Tai Chi.

Xu Hui came over and said, "Chang'an Ling, the warriors Xun and Yuan Tiangang are here."

The movements of practicing Tai Chi did not stop, Li Zheng said: "Let them in."

Xu Hui nodded and invited people in.

Yuan Tiangang has almost recovered, but he is obviously in poor health with a cane.

Li Zheng was still practicing Tai Chi.

The warrior Xun and Yuan Tiangang looked at each other, not knowing what to say.

The atmosphere was quiet for a long time.

After finishing a set of Taijiquan, Li Zheng stopped his movements and let out a long breath, "If you two have anything to say, just say it."

Yuan Tiangang said: "Can you clear away the left and right? There are some things that the poor Taoist and the samurai don't want others to know."

Li Zheng nodded and gave Xu Hui a look.

Xu Hui left with the other maids.

After everyone left, Li Zheng said, "Can we talk now?"

The warrior Xun said: "Li Zheng, the old man has always kept a secret about the little girl's life experience."

Li Zheng said: "I didn't say it directly."

Fortunately, Li Zheng didn't say it directly. Only Yuan Tiangang, Samurai Xun and Wu Mei knew that sentence.

Yuan Tiangang said: "A misunderstanding in the past, let Pindao understand now, it may lead to disaster in the future."

The heroine Wu, if this son is a woman, he should be the master of the world.

Li Zheng was drinking tea and said to the warriors Xun and Yuan Tiangang: "Are you worried that that sentence will come true? If you are afraid of chaos in the world, there is no need for it."

Yuan Tiangang looked at Li Zheng suspiciously.

Li Zheng said in a low voice: "The center of power in this world is in Chang'an, as long as Wu Mei is kept away from the center of power, maybe it will be fine."

The warrior Xun stepped forward and said, "Li Zheng, I have a request."

"please say."

The samurai Xun and Yuan Tiangang looked at each other again, and seemed to have reached some kind of consensus.

"Can you take Wu Mei as your disciple?" Samurai Xun said.

A sip of tea choked his throat, and Li Zheng coughed.

Seeing Li Zheng's reaction, Yuan Tiangang said: "Li Zheng, in fact, being poor has counted your fate. Logically speaking, your fate should be poor and poor, but you can be rich and live a poor life. There are countless ways to tell people, but you, Li Zheng, can't see through your fate."
