In a short time, Li Er changed his armor.

And Cheng Biting Jin put on a bright light armor, and under the reflection of torches at night, he blinded people's eyes.

Niu Jinda, Li Jing and others were all excited.

Since the Turks were wiped out, these guys, who are known for cutting people, have lost their fun.

Now there are people who can't open their eyes to attack Chang'an, so what's the point?

Yes, everyone didn't get into the account, some were just excited.

Li Er was carrying a long knife, with a fierce momentum, and with a wave of his hand, everyone followed him out.

As soon as they walked out of the palace, they saw a fast horse galloping towards them.

The knight on the horse jumped down, and it was Li Junxian, the commander of the forbidden army.

Li Junxian bowed down and said: "Your Majesty, there is a false alarm, the scouts have found out clearly, the people and horses outside the city are not the thieves who attacked Chang'an City, but some people, who come and go to the north and east of the city, and seem to be transporting something. ”

What?

A false alarm?

The civil servants were relieved one by one.

The generals were disappointed.

originally thought that I could cut people, but who knew it was a misunderstanding.

The eldest grandson Wuji said uneasily: "General Li, is the information true?" Don't fall into the trap of the thieves! ”

Li Junxian said: "Lord Eldest Sun, you can rest assured, those people who are transporting things are all under the command of Cheng Chubi, the second son of the Lu State Mansion, this matter is Chen Chu's doing, I have sent someone outside the city to verify with Chen Chu." ”

Burst!

Li Er almost vomited blood.

It turned out to be Chen Chu.

This kid is not at ease at all.

In the middle of the night, such a thing happened, which alarmed the civil and military forces of the Manchu Dynasty.

Li Er turned around and said, "That is the case, Aiqing, go back and rest for the time being, send someone to keep an eye on Chen Chu, you can't let him mess around anymore." ”

Li Er was afraid.

This kid can't sleep well.

Then the people dispersed with their own thoughts.

……

Next.

Early dynasty begins.

The courtiers, all with red and swollen eyes, pale faces, and languishing.

It's not overindulgence.

Instead, he was frightened by the movement outside Chang'an City last night.

I saw Duan Lun, the secretary of the Ministry of Industry, stand up and say, "Your Majesty, the minister has a happy event to congratulate Your Majesty." ”

Li Er was also exhausted and asked, "Duan Aiqing, what's the happy event?" ”

Duan Lun said: "Your Majesty, before, the iron mine in the north of the city played, saying that there are more and more iron slag, there is nowhere to pile up, discard at will, it will only make the land can no longer grow food, and to transport it to other places, it takes a lot of manpower and material resources, this matter, has been a headache for the imperial court, for this reason, the court also spent a lot of money to buy a large piece of land to pile up iron slag, but it can not solve the matter, now, this matter is solved, according to reports, last night Chen Chu organized tens of thousands of people, overnight, the iron slag was transported away a lot...... The chief officer of the iron mine played early this morning, imploring His Majesty to order Chen Chu to transport all the remaining iron ore slag. ”

Li Er was surprised: "You mean, Chen Chu made a big fanfare last night just to transport away those useless iron slags?" ”

Duan Lun nodded: "This matter is absolutely true!" ”

Li Er couldn't help but be curious: "But, what is the use of iron slag?" ”

Duan Lun shook his head: "I don't know, the craftsmen of the Ministry of Industry, and no one knows Chen Chu's purpose, but this is always a good thing." ”

Li Er thought about it, but he didn't figure out how bad this matter was for the imperial court.

So he said happily: "Okay, according to what Duan Aiqing said, all the iron slag from the iron mine in the north of the city belongs to Chen Chu, let him use it at will, hmm...... It's not as good as this, the iron slag in the world should also be given to Chen Chu, Chen Chu can use it at will, what do you think? ”

"Your Majesty."

The crowd agreed.

The kind of waste that no one wants, and there's no place to put it.

Since Chen Chu wants it, then give it to him.

As for what Chen Chu is going to do, this is not what everyone cares about.

On the contrary, many people quietly ridiculed Chen Chu for being born in the countryside and being an uninformed hillbilly who wanted this discarded iron slag.

……

Outside the East Gate.

Near the pencil manufacturing plant.

Next to the stove under the hills, the construction of various houses has begun.

Chen Chu looked at Cheng Yanjin dumbfounded, and asked, "Fourth brother, are you saying that my father ordered that I can use the iron slag in this world at will?" ”

Cheng Yanjin nodded and said: "Fifth brother, you don't know, the imperial court has had a headache for a long time about the fact that this iron slag has nowhere to be piled up, and now you actually want this thing, Your Majesty has no reason not to give it, and the Manchu Dynasty is very happy, but a few guys laugh at you and say that you don't know ...... I punched one of the guys. ”

Lao Cheng's temperament is impulsive.

Chen Chu was a little helpless.

He pouted.

Laugh at me for not being knowledgeable?

Phew!

A bunch of backward old-fashioned people.

This iron slag is a treasure, not to mention anything else, it is used to make cement, but it is the best, better than any other material.

Therefore, at first, he was worried that Li Er and the others would react, and he was reluctant to release the iron ore slag, so he let Cheng Chubi make a big show and organized thousands of people to transport a batch back.

I knew that these turtles didn't care about it at all, so I was still in a hurry.

Chen Chule was happy.

With a large amount of free iron slag available, the cost of building cement in the future is low.

Cheng Yanjin stood aside, watching the craftsmen busy, and asked curiously: "Fifth brother, tell me, what is the use of this iron slag, I promise not to say it." ”

Lao Cheng is a friend of Chen Chu.

And the character is trustworthy.

Plus cement, sooner or later, it will come out.

Therefore, he said bluntly: "Fourth brother, I won't tell you anything, this iron slag can be used to build cement." ”

"Cement?" Cheng Yanjin looked curious.

Chen Chu beckoned.

Zhu Neng took a fist-sized piece of cement, but it was solidified.

Chen Chu introduced: "This is made of cement, cement is made of soil, stone, and iron slag, with cement, you can make all kinds of shapes of things, and they all have a characteristic, very hard." ”

Cheng Yanjin looked at the unsightly thing and doubted: "It's hard? Fifth brother, don't lie to me! ”

Chen Chu smiled: "You can try." ”

Cheng Biting Jin took it with his left hand, held it in his hand, and then clenched his right fist and smashed it with a fist.

There was a muffled thud.

The cement block does not move at all.

Cheng Biting Jin's fist was broken and bleeding.

Chen Chu's eyes widened.

Holy!

I knew that Lao Cheng lacked a tendon, but I didn't expect it to be such a tiger.

But seeing that Cheng Yanjin was the same as no one, he said: "Okay, yes, if this thing is used to build a city wall, I am afraid that it will be useless no matter how the enemy attacks, good thing, fifth brother, you are simply a genius...... Hahaha......"

Cheng Yanjin left happily, even if the back of his hand was bleeding, he didn't care.

Chen Chu and the others all showed admiring eyes.

This special mother is a real man!

For a time, many people's admiration for Cheng Yanjin spontaneously emerged.
