The three symbols that caught his eye made Li Chengqian a little confused.

"Ding, what?"

Li Chengqian looked at Qin Jue with a confused expression.

Some wonders, what is this?

I don't understand it at all.

"It's TNT!"

Qin Jue patted his face, and then said to Li Chengqian: "Study this thing carefully, when you really can't help it, make this, tie it to your body, hold a torch in your hand, whatever you say, your father will promise you." ”

"Really?"

When Li Chengqian heard this, he was directly excited, there is such a powerful thing in this world?

Can you make your father obey?

Li Chengqian happily opened the book.

After reading it, I swallowed a mouthful of saliva.

Isn't this fucking gunpowder?

What TNT?

Li Chengqian had the urge to scold people, so he tied this to his body and brought a torch.

It's a person who wants to slip away!

This Nima is the number of naked jade and stone burning.

If you don't agree, I'll burn you with jade.

And that's the last trick?

It seems to make some sense.

If you fail, you will die, even if I am the prince, it is useless, the people are gone, don't you change the prince?

That's a real trick.

It's just that this trick is a bit excessive......

Let's try the previous method first.

But this thing can be studied.

There is obviously a difference between pondering by yourself and pondering with a book.

When I pondered it myself, it would be over with a little accident, but reading what was written in this book was quite rigorous.

If you do your own research, you should be fine.

No, you can't study in the palace, you have to study in another place, otherwise you will be stopped by your father.

"Remember, this thing must not be leaked! If it is leaked, it will be a catastrophe for Datang! ”

Qin Jue stared at Li Chengqian deadly, and then said: "If you leak it, don't say that you are the prince, even if you are the emperor, I will kill you with my own hands!" ”

Qin Jue threatened Li Chengqian, and then said: "If you can't study it, you are not allowed to find someone to study together, if you have to find someone to study together, you must get my consent!" Do you understand? ”

He had to be cautious about it.

This thing is something from the Ming Dynasty a thousand years later, if it is accidentally leaked out, it is really a catastrophe for the current Tang Dynasty.

If the other party learns the things in this book, he can cause indelible damage to Datang.

So what is in it must not be revealed.

"Lone is not a fool, how can he tell others about this thing?"

After Li Chengqian finished speaking, he said to Qin Jue: "In case someone else wants to use this to assassinate Gu, how can Gu resist?" ”

“……”

Qin Jue's face was speechless, why did you think about this?

The ideological realm is too low!

After a while, Li Chengqian said again: "If you use this, and my father still doesn't agree, won't Gu want to die?" ”

"Life is precious, but love is even more valuable. If it is free, both can be thrown. ”

Qin Jue silently said to Li Chengqian: "For freedom, bloodshed and sacrifice are inevitable. Come on, you can! ”

Li Chengqian's hearing made his blood boil.

Well said!

For freedom!

Yes, bloodshed is inevitable!

Don't be afraid of loneliness!

It's just that he didn't expect that this was for his own freedom, and it was estimated that he would be the only one who would shed blood and sacrifice at that time, or drag Li Shimin along.

"I'm going to study it alone."

Li Chengqian ran away with two books in his arms.

Looking at Li Chengqian's departing figure, Qin Jue smiled and didn't say anything.

This Li Chengqian should change his ending.

At least he won't end up depressed.

After Li Chengqian left, Li Chunfeng, who had been thinking at the door, walked into Qin Jue's house.

"Have you thought about it?"

Li Chunfeng nodded and said to Qin Jue: "Actually, this is very simple, as long as you take the result as a normal number, and then write the formula according to the conditions, and then it will be very simple." ”

Li Chunfeng is an arithmetic classic who has studied a lot, and although the binary system of equations is new to him, he can basically master it after reading it and thinking about it for a while.

"Master, teach me something a little harder."

Li Chunfeng looked at Qin Yu with a smile on his face, wanting to learn something a little more difficult.

Qin Jue looked at Li Chunfeng and said, "Do you know that there are some things that can only be understood and cannot be spoken? ”

Qin Yu didn't pretend to be profound, but he really couldn't think of anything more difficult.

You can't let Li Chunfeng prove that 11=2.

He didn't understand it himself.

As for calculus, definite integrals, etc., I have forgotten everything.

It is impossible to teach Li Chunfeng at all.

He's just half a bucket of water, and he's a real boss.

There are some things, point to point, can't say much.

If you talk too much, you will be exposed.

At this time, he must stand on the shelf, and he can't let Li Chunfeng know that he doesn't understand anything.

After Li Chunfeng listened to Qin Jue's words, he immediately said: "Teacher, you can give me questions, I want to study!" ”

Qin Jue looked at Li Chunfeng's expression, it was a look of thirst for knowledge.

After a while, he sighed, and then said, "Then I'll give you a title." ”

Qin Jue thought about it, it was impossible for ordinary topics to be difficult to catch Li Chunfeng.

So Qin Jue drew a picture directly on the ground, and then said: "Look at this picture, you know that this angle is 30 degrees, this angle is 60 degrees, and then this side is two inches, this side is four inches, find out how long this side is." ”

Qin Jue drew an extremely abstract diagram on the ground, and then said to Li Chunfeng: "You go and solve this problem." ”

“？？？”

Li Chunfeng was stunned: "What is thirty degrees?" What is 60 degrees? ”

What is this noun?

How come I haven't heard of it?

Li Chunfeng was directly dumbfounded.

"Alas!"

Qin Jue sighed, and then explained to Li Chunfeng, what is called angle, and then Li Chunfeng suddenly realized.

"I see!"

Li Chunfeng began to look at the graph and calculated.

But he looked at the picture and was confused.

What is this?

The conditions are all clear.

I still don't understand Mao!

What does this mean?

This line has nothing to do with the other two lines!

What's the use of knowing these two angles?

it?

What kind of title is this?

Li Chunfeng grabbed his hair in pain, feeling like he was a fool, and he didn't know what it was.

When I looked up, Qin Yu was gone at this time.

After Qin Yu stabilized Li Chunfeng, he slipped away.

Li Chunfeng didn't see Qin Jue, lowered his head a little, and continued to look at the picture.

"Ahh

After a long time, Li Chunfeng suddenly shouted, and the voice was loud and high, alarming everyone in Qin Jue's mansion.
