The last time Zhang Yi got news of Kong Kejian from Zhu Biao, he was talking about the Kong family.

Zhang Yi didn't take this matter to heart, he always thought that history was still advancing according to the original course.

In the first year of Hongwu, Xu Da broke through the Yansheng Mansion, and according to Zhu Yuanzhang's order, he invited Kong Kejian to enter the capital to face the saint.

It's a pity that the contemporary Yansheng Gong's heart is to the Northern Yuan, and he can't get sick with the idea of betting on both sides, but he just sent his son Kong Xixue to face Xu Da, Xu Da couldn't ask him to appear, so he could only send someone to send Kong Xixue to the capital under the dilemma.

……

Zhang Yi doesn't remember this history very clearly, but it should be correct.

Then why is it that the one who comes to the capital now is Kong Kejian, the Holy Father of Yan?

"Did I not make it clear that day?"

Zhu Biao's behavior towards Zhang Yi was very strange, adding:

"Kong Ke insisted that he couldn't get sick, and the emperor Long Yan was furious, and ordered the general Xu Da to personally go to [invite] Yan Shenggong to go out of the mountain, and personally send Yan Shenggong to Beijing to show respect!"

The word respect is particularly ironic.

But Zhang Yi had no intention of biting the word Wenjue, and he set off a storm in his heart, and sure enough, this history was changed.

Xu Da actually returned to Beijing, and now that the Northern Expedition is in full swing, he actually returned to Beijing?

It can be seen from this that Zhu Yuanzhang "attaches great importance" to the Confucius family in Qufu, but this kind of attention is bloody......

"I wonder how this history will evolve?"

Zhang Yi was a little surprised!

"Forget it, the affairs of the court are not something that we ordinary people should worry about!"

Zhu Yuanzhang changed the topic at the right time.

"By the way, Zhang Yi, what is this?"

Zhu Yuanzhang took out something from his cuff and put it on the table.

Zhang is normal, Zhang Yuchu's father and son looked at it, but it was a small wooden stick as thick as chopsticks, but the wooden stick had been cut with a knife, revealing the black core inside.

"What is this?"

The father and son of the Zhang family were also curious.

Zhang Yi took a look, wasn't this the pencil that Huang Mu took away that day?

He was rebellious since he was a child because Zhang normally regarded him as a bad star, which led to the fact that although Longhu Mountain also invited Mr. to come up to teach, he was not friendly to him, Zhang Yi teased Mr. a few times, and no one on this mountain taught him to read and write.

Although he used to live a comfortable life, sometimes when he needed to write and draw, Zhang Yi felt that it was difficult to use a brush, so he made a few pencils himself.

"It's a pencil!"

Regarding the pencil matter, Zhang Yi didn't have any exposure pressure, he didn't bother to make up any stories about the immortals teaching the law, and said directly:

"This is the technology I saw from the book of heaven, I learned it, this is also the technology of the future!"

"Shhh

Except for Zhang Yi, everyone present gasped.

"This is the pen used by the people of the future, how weird!"

Zhang Yuchu looked at the pen on the table, full of curiosity.

Zhang Yi smiled, the pencil is indeed the technology of the future, and now it is nearly 200 years since the advent of the graphite pencil stick, the prototype of the pencil, and the evolution from the pencil stick to the modern pencil is nearly 300 years later.

"This is a pen from 500 years later!"

"Five hundred years?"

Zhu Yuanzhang's expression was not calm, and when he took out this pencil, he actually didn't think much about it.

He had used a pencil, and it was a relatively good thing, but that was all.

The pencil itself is not important, the important thing is that Zhang Yi told him that this is the technology five hundred years later.

He remembered the pox method, and his eyes became different.

More and more evidence shows that Zhang Yi's vision of the future is real, and there is no room for doubt.

Can this guy bring the technology of the future to this era in advance?

Zhu Yuanzhang thought of the meaning behind it, and his scalp was numb, if he could get some key things, the national fortune of the Ming Dynasty would be unimaginable.

"Five hundred years later, what kind of world is it, does the Ming Dynasty still exist?"

Everyone was curious about the future world, and Zhu Biao was the first to ask questions.

Zhang Yi was mentally prepared, he shook his head:

"I don't know, what I can see is just a fragment, and the book of heaven doesn't allow me to see the future at any time......"

"And what kind of clip do you see?"

"I've seen buildings taller than mountains, and I've seen iron birds flying in the sky...... The people will have enough food and clothing, and they will no longer be plagued by hunger and cold......"

Zhang Yi casually said some clips of the future, which made a group of people confused.

Does such a world really exist?

If Zhang Yi said that in the future, everyone will live in the blessed land of the cave and fly with the sword, maybe they will be more acceptable.

People's imagination has boundaries, no matter how Zhu Yuanzhang imagines it, they can't imagine the scene of an iron bird flying into the sky, they still want to ask again, Zhang Yi shook his head, saying that he didn't know more.

Lao Zhu and the others were lost.

However, Zhu Yuanzhang is not desperate, Zhang Yi can't see it today, it doesn't mean that he won't see it in the future.

He kept Zhang Yi by his side, wasn't it just for this possibility?

"Pencil!"

Looking at this pen again, Zhu Yuanzhang's thoughts are different, he originally thought that this kind of pen was just interesting and ingenious, but it was not very good.

In fact, Zhang Yi also understands this truth, in this era, the monopoly of knowledge is in the hands of the "scholar" class, and the pencil is not much use.

The scholars looked down on it, and many of the people who could use it were illiterate.

Zhang Yi just made his own drawings by himself, and the hard pen does have the convenience of a hard pen, but it is not suitable for this era.

"I've used this pen before, and it's a little awkward, but if you get used to it, the writing speed will be much faster!"

"Zhang Yi, I can buy the recipe for this one with you, and I'll be responsible for selling these pens?"

Zhu Yuanzhang's proposal, Zhang Yi naturally would not disagree.

He is now short of money, and he can still get a sum of money by selling this house to Huang He.

Zhang Yi found a pen and paper and wrote down the recipe, and Zhang Yi did not reserve about how to compress the refill.

Zhu Yuanzhang was very satisfied with Zhang Yi's upper path and said:

"I'll ask the boss to send you the money when I go back, and if my business is doing well, you'll also have dividends every year!

You see, how about five hundred taels? ”

The method of making the pencil is not too important, but Lao Zhu wants to set a precedent from Zhang Yi, which can ensure that Zhang Yi can contribute every new technology he sees in the Book of Heaven.

If Zhang Yi's heart is chilled this time, with the temperament of this little rabbit cub, he will definitely not show off at will.

Zhang Yi was overjoyed, five hundred taels of silver was a lot in the early Ming Dynasty, and the technique of pencil making was not a big deal for him, and it was best to sell silver.

Moreover, this Uncle Huang has many ways, and it is inconvenient for him to realize the technology in his hand as a Taoist priest, which is just right at this time.

After Zhang Yi finished writing the recipe, he also accepted the silver sent by the housekeeper.

This meal was at the end of the meal, and when he saw Lao Zhu put away the recipe, he asked casually.

"Where is Uncle going to sell his things?"

Lao Zhu pretended to be mysterious:

"Have you forgotten, whose path did I take when I first came to the capital?"

Frequent spring?

Zhang Yi thought about it, it seems that Zhu Yuanzhang wants to sell the pencil to the military!
