Kong Yingda hurried to the prince's bedroom and saw His Royal Highness. However, Li Chengqian was lazy, as if he had not slept all night, as if his body had been hollowed out by wine and sex.

Kong Yingda immediately saw the books scattered under the bed, and was shocked when he saw them.

Isn’t this the textbook that has been circulated in Erpigou?

Oh my God...

My crown prince of the Tang Dynasty actually...

Be calm and calm. Your Majesty also appreciates this textbook. If you take this opportunity to attack this book at this time, not only will the prince not be happy, but even your Majesty will be furious.

So Kong Yingda smiled and said, "Your Highness, where did this book come from?"

"Why, Chen Zhengtai sent the orphan to the orphanage, do you want to see it? Show it to you, you don't understand it either."

Kong Yingda: "..."

I think that Kong Yingda, a well-known scholar in the world after Confucius, still needs to read this broken book?

Kong Yingda smiled and said, "Your Highness should be well cultivated now."

"But Gu already feels that his body has recovered almost." Li Chengqian said: "Or why don't Gu stay and jump and see?"

Kong Yingda was so scared that her face turned blue and hurriedly said, "Your Highness, no, I will say goodbye first."

Li Chengqian was immediately happy. He knew what Master Kong meant to come here, and he was just scaring him.

It should be noted that in this Tang Dynasty, the most difficult thing is the crown prince, but the worst one is the crown prince’s teacher.

After all... you can't beat or scold this guy. If he is good at learning, it means he is smart, pure blood, and good.

But if he is too naughty, then you, the teacher, has no idea what to teach.

Seeing Kong Yingda leaving, Li Chengqian ordered the eunuch to pick up the book that was scattered on the ground when he was sleeping soundly last night, and then started reading again.

He gradually began to find a trick. This book... has to read from the beginning and understand the content before it can understand it later. Many of the content, once you start to really think about it, it will inevitably make people realize that the knowledge here is really interesting.

Of course... Li Chengqian thinks this may be a fallacy, after all...

Why is the earth round? Not round, and...there is a kind of qi everywhere. What is this qi? As for gravity, it is even more unreliable. Can it fly if it is lonely without gravity?

Half a month later, Li Chengqian felt that his leg injury had healed, so he couldn't help but sit on a chariot and head to Erpigou.

When I arrived at Erpigou, I found that it was very lively. The most lively place was a shed. Although the shed was simple, there was a long queue outside. Many people who looked decent were lined up here...

Li Chengqian couldn't help but feel strange and ordered the eunuch to ask.

After a while, the eunuch came and replied: "If you go back to your highness, these people... will try their best to settle down."

"Setting up?" Li Chengqian was stunned and said in surprise: "What does it mean to settle down?"

"As long as you are not a slave or a tenant farmer, you can come to Erpigou to settle down. I heard that Erpigou's settlement standards are very strict, but many people still want to try it. Not to mention ordinary people, even some small officials and merchants have come!"

Li Chengqian said in surprise: "The Erpigou is so desolate, are they willing to come?"

"Your Highness doesn't know anything. I heard... Here in Erpigou..., it's hard for ordinary people to find a job outside. But here, as long as a strong man is willing to do many jobs, he can not only have to worry about three meals, but also earn one or two hundred cents a month. If he has some skills, he can earn a few cents of money here. Therefore, many people want to settle here, not only are there small officials, but also merchants and craftsmen... "

At this moment, Li Chengqian interrupted the eunuch: "Let's wait, what are these little officials and merchants doing here? Do they look down on this benefit?"

The eunuch glanced at Li Chengqian and said, "Your Highness... Actually... I actually want to settle down if I have descendants. After all, these people are not aristocratic families. They seem to be able to do business and earn some money today, or they can find an appointment in the yamen with luck. But I heard from them that this person is alive, not those iron-clad aristocratic families, and there are always ups and downs. There are some small wealth today. Who knows what tomorrow will be? I live a good life and my descendants know what it will look like? I come here... I just want to find an iron job for my future and for my descendants. If I really suffer in the future, or my descendants will not become a weapon, Erpigou will never let myself be hungry."

Li Chengqian probably understood that not everyone in this world can enjoy eternal wealth like the five surnames and seven sects, or like the Wei family and Du family in Chang'an.

The more small officials and merchants are, the more likely they are to feel anxious. After all... Although they have some wealth, there are too many things in the world. Once they fall from their own class and become common people, they will be doomed.

In Erpigou, ordinary people have books to distribute, so that they can learn by themselves without satisfaction. As long as they have hands and feet, there are many manual recruitment. This is a layer of guarantee for a certain class.

Li Chengqian said: "In this way, Erpigou is going to be overcrowded now?"

The eunuch shook his head: "This is not. There are very few people who can settle down. It is said that the conditions are very harsh. Many people just come to try their luck. It is said that it is only one year, but there are only one thousand households. However, I also heard that it is because of the fewer posts, so it is even more popular."

"It's really strange." Li Chengqian shook his head: "He is rushing to be neighbors with Senior Brother Gu. It seems that Senior Brother Gu is quite popular. You can also queue up for Gu and Gu will also settle in a house."

The eunuch was startled: "I dare not."

Li Chengqian did not force him and asked someone to inform Chen Zhengtai. After a while, Chen Zhengtai came in a hurry!

Chen Zhengtai's skin turned whiter and the weather gradually became colder, so he was dressed quite bloated. After greeting Lee Seung-qian, Chen Zhengtai said, "Why is Your Highness here?"

"If you have any questions, I'll ask you." Li Chengqian got out of the car and leaned on a stick. He still felt a little inconvenient when he walked out. Fortunately, the bones were almost all the way!

He continued with great energy: "Your fireworks...you can see a little bit of your eyebrow. Your book says that using some flammable substance to close it and ignite it will produce a large amount of gas and heat. The original small gunpowder instantly expanded and caused an explosion in a narrow space. Is that true?"

Chen Zhengtai was surprised that the prince had actually read the book, and... the prince actually read the book.

Seeing Li Chengqian's serious look, he said, "That's right."

"But I don't believe it. For example, we found tincture oil, right? Can this tincture oil explode even if it burns in a confined space?"

"It depends on the situation."

"Then have you tried it?"

"Ahem... I dare not try."

Li Chengqian: “…”

Then he gave Chen Zhengtai a blank look.

"If you don't try, I won't believe what you said in your book."

Chen Zhengtai smiled and said, "Actually, although the prince knows this principle, I know that as long as I find these flammable things, I can save them successfully."

Li Chengqian still looked disbelief.

Chen Zhengtai was very pleased that Li Chengqian was so studious, and as a young man, he should have the spirit of being as studious as he was.

So I was busy searching, and then, in the evening, a "firecracker" was ready.

As someone prepared the lead, Chen Zhengtai and Li Chengqian, who was leaning on a stick, stood in the distance. At this time, the sky was a little dim. As the lead was ignited, after a while, suddenly... a sound suddenly came from under the night sky.

Bang...

Li Chengqian was not mentally prepared, shivered and almost fell down. Fortunately, Chen Zhengtai supported him.

The explosion sound is almost a weakened version of a two-pick.

In Chen Zhengtai's opinion, it's just Err.

But Li Chengqian was ecstatic and exclaimed: "Senior Brother, have you seen it? Did you see it? The light just now, the light just now...ah... I was so scared to death."

As he said that, he walked wildly towards the explosion with a stick. The original container had been blown to pieces, but the saltpeter inside had long disappeared!

Li Chengqian looked down at him and suddenly said, "Senior Brother, come."

Then I saw that there was a mouse on the ground, which seemed to be injured by an explosion, with blood and flesh on the lower abdomen, struggling desperately, making a whine.

"Can you still hurt the rat?" Li Chengqian thought, "If you say this, wouldn't you still hurt someone?"

"In theory, that's the case." Chen Zhengtai immediately smiled bitterly: "But... I encountered a difficult situation, that is... With the power of this explosion, if you want to hurt someone, you must increase the amount of gunpowder. Once the dosage is increased, this thing will only have dozens of kilograms to achieve its effect."

This is just black gunpowder. Chen Zhengtai is not optimistic about the power of this black gunpowder, although this is simply a magical tool in Li Chengqian's eyes.

Li Chengqian looked at Chen Zhengtai in surprise and said, "How powerful can dozens of kilograms be? Can it really hurt people?"

Chen Zhengtai thought for a while: "Your Highness, the key to the problem is here. It is extremely difficult to hurt people such a heavy thing. After all, people are not stupid and will not rush towards this gunpowder. Instead of spending a lot of effort on gunpowder, it is better to throw a stone. Therefore... I think... this thing can only be used as fireworks for the time being. But..."

What Chen Zhengtai remembered is that it is only the primary stage of gunpowder, and its practicality is indeed not high unless the gunpowder technology continues to improve.

But it may not be useless: "Unless... there can be something to carry this gunpowder... the best way is to airdrop."

"Airdrop..." Li Chengqian was stunned: "You mean, man is in heaven? Oh, isn't it written in your book? There are gases that are lighter than air in the world. As long as this principle is applied, people and things can be brought to heaven, right?"

"Uh..." Chen Zhengtai truly understood why the Li family could win the world. It was really good to grow it. If he was in the pig farming world, whether it was his mentor or Li Chengqian, he could definitely be a breeder!

Chen Zhengtai said: "In theory, that's the case."

"So why not give it a try?"

"Let's take a look at it then." Chen Zhengtai is busy with a lot of things now. First of all, he has to make money, but he doesn't take this matter to heart.

Li Chengqian glared at his eyes: "What are you saying? You taught me how to read the book. I read it day and night, but my senior brother is lazy? It's unreasonable. I'm going to get angry. I'm going to eat all the chickens and pigs in Erpigou."

Chen Zhengtai: "…"

Li Chengqian decided to live in Erpigou.

He has a stubborn side in his nature. The best building in Erpigou is Erpigou University Hall.

Immediately afterwards, he saw an old acquaintance, Cheng Chumo, who was also limping and leaning on a cane.

Cheng Chumo limped and made a yoke sound from his mouth.

He finally got his home as he wished, but... the university still needs to wait for a survey exam, and only after the exam is over, will he be allowed to enter the school, of course...

In order to make people pass the exam better, the university also held a training class for the entrance exam. Compared with the cheap tuition fees at the university's opening class, the training class is more expensive. Of course... the training is more expensive, which is also very reasonable.

Cheng Chumo was sent to the training by his father. In short, General Cheng had already spoken that Cheng Chumo must enter school. If he couldn't enter, he would be the first to kill Cheng Chumo. After that, he would draw his sword to find the third uncle of the Chen family, and have a white knife in and a red knife out.

Therefore... Cheng Chumo became a national treasure panda in the training class. Everyone in the Chen family cared about his studies very much. Li Yifu, who was arrested as a temporary teacher in the training class, had been entrusted by his third uncle and was specially cared for Cheng Chumo's studies.

At this time, Li Chengqian was walking back and forth in the backyard of the school with a stick, and he wanted to practice rehabilitation more.

Then... he saw the person coming towards him, and he was also leaning on a cane, learning from his own appearance, staggering step by step.
