The Imperial Study.

At this time, Li Shimin was talking to Wei Chigong around a plow.

"Your Majesty, this is a plough made according to that picture, and the minister feels that it is useless."

Wei Chigong said to Li Shimin.

In fact, this plow was built by Wei Chigong himself.

The best iron in Datang is used, but this plow was made, although it was easy to use at first, but after plowing a few acres of land, the plow blade was directly wasted.

It's either a curl or a gap.

How else does this work?

Although the labor-saving is a little labor-saving, it is too labor-intensive.

It doesn't work at all.

"Are you sure you're using fine iron? And not defective? ”

Li Shimin did not doubt that what Qin Yu gave was not a good thing.

Because Wei Chigong said that this thing was quite easy to use at the beginning.

But it didn't take long for the plough blade to curl up and gap.

It's not a matter of plowing, it's a question of iron.

This iron is not good, so this plow is not good.

"Your Majesty, how can the minister fool you! This fine iron was bought by the minister out of his own pocket at the house of the eldest grandson Lao Yin, and it took more than ten times to get the fine iron! How can it be a defective product? ”

Wei Chigong shook his head, he had all passed through his hands, and he knew that these irons were all refined iron, although they were not as rare as Bailian Steel, but they were also high-grade refined iron.

This kind of refined iron can't make this thing, so do you have to use 100 steels?

If this is made from 100 steels, what other people can afford to buy this?

In the Tang Dynasty, 100 steels were quite rare, and these things were all made into divine weapons without exception, how could anyone use 100 steels to make plows?

Isn't this a tyrannical thing?

"Jingde, you go to the outskirts of Chang'an to find Qin Jue."

Li Shimin pondered for a while, and then said to Wei Chigong: "You bring this plow over and ask him what is going on, this plow, I am going to promote it to the whole world when the yuan is changed next year, and name it after the name of my year, this thing must not go wrong!" ”

"Yes!"

Wei Chigong nodded, then put the plow away, wrapped it in a huge package, and quickly left the palace.

At this time, in Qin Yu's house, Li Chunfeng's pale hair was red.

Because Li Chunfeng really couldn't think of how to solve this problem, he kept scratching his hair.

At the end of the day, because I really couldn't figure it out, I had a breath in my heart and sprinkled it directly on my hair.

A large piece of hair was pulled out, and blood suddenly came out, dyeing the white hair red.

Then I heard Li Chunfeng's scream like killing a pig.

Qin Jue ran over and was a little embarrassed when he saw Li Chunfeng's appearance.

Are you going too far?

The topic is very simple for him.

Because the picture was drawn by Qin Jue blindly, he drew a triangle, and there was no right angle at all, and he told Li Chunfeng that one angle was thirty degrees and one angle was sixty degrees. Then he told Li Chunfeng about the two side lengths, and then asked him to ask for the third side length.

In fact, as long as Li Chunfeng knew that the three corners of this triangle add up to 180 degrees, he would know that in fact, this triangle that is not drawn like a right triangle is a right triangle.

But Li Chunfeng didn't know this, just looking at the picture, he didn't know these things at all.

Keep staring at this picture.

As long as you don't know the trigonometric sum of triangles, you will never be able to solve this problem.

If Li Chunfeng wants to do this problem now, he must first study the sum of the inner angles of the triangle.

How to study this kind of thing is none of Qin Jue's business.

"Li Chunfeng, can you be quieter, draw this picture down and take it home to study it yourself! Don't cry wolf here, study well, calm down and study, when you study the hidden information in this topic, you will know that this question is very simple! ”

Qin Chunfeng scolded this Li Chunfeng, and then Li Chunfeng left Qin Chunfeng's house in despair and headed towards Chang'an, he vowed to solve this problem.

For him, it's fun to have challenges.

After Li Chunfeng left, Wei Chigong came to Qin Jue's mansion with a huge package on his back.

Qin Yu can be regarded as knowing Wei Chigong at this time.

At that time, when facing the Turks, Wei Chigong's bravery, Qin Yu had still seen it.

"General Wei Chi, why are you here with me?"

Qin Yu is quite curious, and he doesn't seem to have anything to do with this person.

What is this guy doing here with such a big package?

Do you send it by courier?

But this is ancient, there should be no express delivery, right?

"Your Majesty asked So-and-so to come to you and let you see what the hell is going on?"

Yu Chigong unwrapped the package.

Qin Jue looked at the pile of used plows inside.

Some of the plough blades are broken and notches come out, and some of the plough blades are curled.

These are used plough blades.

And it's all curved plows.

With so many zigzag plows, it seems that Li Shimin has started experimenting.

It doesn't seem to be very good.

"What kind of iron are these plows made of?"

Qin Yu already knew what Li Shimin meant.

Li Shimin's meaning is obvious, you can't do this, why are they all like this?

How can I spread this level!

"It's all made of fine iron! The best fine iron! ”

Wei Chigong said to Qin Jue: "These plows, the most powerful one, only ploughed five acres of land, and then curled the blade, and the other three or four acres will not work."

Do you think it's a problem with the design of the plow, or is it a problem with iron? ”

"Have you tried it with 100 steel?"

Qin Jue looked at Wei Chigong and asked, "My plow, at worst, can only be used with 100 steel, if you use ordinary iron, the strength is not enough at all." ”

“……”

Hearing this, Wei Chigong was stunned.

He didn't speak, he even plucked out his ears, and then asked, "What did you just say?" I didn't hear clearly, you say it again. ”

"I said, the blade of this plough must be made of 100 steel, otherwise the strength will not be enough!"

Qin Jue repeated it again.

"Do you know what 100 steels are?"

Wei Chigong looked at Qin Jue, and then said: "Hundred Steel, that's what makes a divine soldier, you actually want to use Hundred Steels to build this?" Isn't this a tyrannical thing? ”

"Tyrannical creatures?"

Qin Jue was stunned for a moment, and then said, "Do you have any misunderstanding of the word tyrannical celestial things?" Or is there some misunderstanding about my curved plow?

This thing is the divine weapon of the people!

What's wrong with using 100 Steel?

Is this a tyrannical thing? How many hundred steels can be made from this blade?

And not the whole plow needs to be made of steel!

The hundred steels you use to build a divine soldier can be used to make at least dozens of curved ploughs.

Which thing is more important, this divine soldier or Quyuan plow, you go and ask Your Majesty, and let Your Majesty tell you whether he wants a divine soldier or Quyuan plow! ”

After Qin Jue finished speaking, he then looked at Wei Chigong and said: "It's just a hundred steel, and it's not a good thing, since I can come up with this design, it proves that I can also get a hundred steel." ”

“？？？”

When Wei Chigong heard this, he was stunned.

Can you get 100 steel?

Impossible.

The birth of such a thing as 100 steels depends on luck.

Some iron casters do anything to make steel.

How did it get into Qin Jue's mouth and become a very ordinary thing?

This shouldn't be!
