Take the system to the Great Tang

This unknown village in Dongying was occupied by Du He and others with violent means, after the intermediate communication of translator Wu San, Du He decided to act according to the plan of No. 10, all the young and strong men went to dig for coolies, those women and children, the elderly, children can do some chores, such as laundry and cooking, etc., at the same time, these people are also hostages, used to contain those young and middle-aged, if you dare to disobey, take your family!

These Dongying people, who originally thought that they were dead, breathed a sigh of relief, and as long as their lives were still there, they could find an opportunity to escape, so they could only temporarily agree to Du He’s conditions and start their own days as Tang coolies!

And in Chang’an City, because of the Ministry of Works talents found by Li Shimin, Zhao Feng and Li Tai easily found limestone, and other materials for making cement were also easily found, and now a bunch of people, including Li Shimin, are looking at a finished cement board in Zhao Feng’s yard!

“Just such a thin stone slab? Old Cheng can penetrate it with one punch! Cheng Yanjin looked at the cement board and said with disdain.

The cement board made of the first fired cement did not reach the ideal level of Zhao Feng, which is a defective product, but this is not a punch that Cheng Yanjin said can be penetrated, this cement board Zhao Feng is proportionally added pebbles and river sand, the hardness is absolutely barbaric! Not to mention the bare hands, people with less strength can’t break it even with an iron hammer!

“Uncle Cheng, I bet with you, if you can punch through my cement slab, that color potion, I will give you a bottle for free!” Zhao Feng looked at Cheng Yanjin and said.

“Seriously!?” Cheng Yanjin’s eyes lit up as soon as he heard Zhao Feng’s words, since the last time he was defeated by Du He in front of so many people in the plundering team, this chaotic demon king has not appeared for a while, according to Cheng Yanjin, Cheng Yanjin has been staying in the martial arts training ground at home to hone martial arts and strength during this time, but the effect is not good.

As one of the top martial generals of the Great Tang, how could Cheng Yanjin be willing to be compared by a junior or a junior who had been drunk!

Originally, Cheng Bitjin also planned to cheat on drugs, but think about the expensive price of that super soldier potion, or practice it yourself, the price of nearly one million even if Cheng Bitjin smashes the pot and sells iron, he can’t afford it!

Now when I hear it, I can get a bottle for free as long as I break this small stone slab in front of me, of course, Cheng Yanjin will not miss this opportunity!

As if afraid that Zhao Feng would repent, Cheng Yanjin directly rolled up his sleeves and shouted “Hi” with enough strength, and smashed a punch towards the erected cement slab….

“Click!” “Ao ~~~~~~~~~~ It’s a pain to kill Lao Cheng!”

Unsurprisingly, this competition was Cheng Bitjin’s loss, and when Cheng Bitjin’s fist smashed into the stone slab, Zhao Feng even heard the sound of bones breaking!

This is inevitable, how can human bones be harder in clay? Even if this is a flawed product, it is harder than your Cheng Yanjin’s fist! You can have a good knot if you smash it up like this without thinking!

In fact, Cheng Biting Jin did use a stone slab that was more harmful than this cement slab before, so Cheng Biting Jin would be so confident, but at that time, Cheng Biting Jin broke the stone slab, although the thing is also hard, but it is also brittle! As long as you give it enough strength to blow even a fist can break it, the cement board is different, hard, but not brittle!

“I still don’t believe it!!” After Cheng An lost money, he was not angry in his heart, and pulled out an axe pinned to his waist and smashed Huashan towards the cement slab!

This finally worked, and I saw that under Cheng Yanjin’s axe, a one-inch deep scratch was slashed on the cement board! But the cement board is still not broken, it is strong enough!

This scene finally moved Li Shimin, who had been watching coldly for a long time, Cheng Yanjin’s ability to do what he Li Shimin is still very clear, holding an axe even a living person will split you in half, now you actually can’t help a so-called cement board that is only half a palm thick?

“How about it, Uncle Cheng, admit defeat, right?” Zhao Feng said with a smile, how can a super soldier potion slow and expensive thing be easily given to you! If it weren’t for the absolute certainty, Zhao Feng wouldn’t have bet with Cheng Yanjin!

“Hmph! Go find a hammer! Be sure to break it all at once! Cheng Yanjin said like an old scoundrel.

“It’s not fun to use a hammer!” Zhao Feng said speechlessly, this Cheng Yanjin is really the Demon King of the Mixed World, he is actually so shameless, he is in his thirties, and he is actually like a child who does not grow up!

Although the cement board is very good, but in the fierce man like Cheng Yanjin holding the iron hammer such a big killing weapon still can not hold on, this is different from the axe such a sharp weapon, the iron hammer is a blunt weapon, can apply a powerful blow to the cement board!

“How much does this thing cost?” Li Shimin saw the key problem at a glance, things are not the key, the key is money!

Since Zhao Feng has already made things, and the pioneer of biting gold through the process has also verified that this is indeed a good thing, just a piece of slap thick can make Cheng bite gold deflated, if it is repaired to the thickness of the city wall… Li Shimin couldn’t think of anything else in this world that could break through such a wall!

Therefore, the value of cement is still very large, at least Li Shimin feels that if it is used to build fortifications, it is much better than the current stone walls!

“Father, I have already calculated that the cost of such a cement slab is less than ten dollars!” Li Tai on the side said.

He was involved in the entire manufacturing of cement slabs, from the firing of limestone, to the grinding of other materials, and then mixing and firing, the most expensive of which is probably fuel! Limestone is not worth much at all, you can buy a lot for ten dollars!

“Ten cents!? This is also too expensive! Li Shimin said in surprise, this ten dollars are insignificant in Li Tai’s mouth, but Li Shimin has never been a small family when considering things, after getting the quotation, Li Shimin simply calculated in his heart how much it would cost to replace a border city with a cement wall, this is not unknown, it is simply scary! It actually costs tens of thousands! You know, this is just a small frontier city! If you change to the city wall of Chang’an….

“Yes, but this is only the cost of the first experiment, and the cost should be reduced after that.” Zhao Feng also nodded and agreed with Li Shimin’s opinion, expensive, is too expensive, this is just cement slab, if you want to use cement to build a dam, you must also add a lot of steel bars to the cement to reinforce, otherwise the cement alone does not need to think about it, they will crack!

In this way, the cost will be greater, but before that, Zhao Feng intends to use these cements to earn some first, anyway, it is impossible to find so many laborers to repair dams and build power plants before the autumn harvest, just practice their hands!

“Your Majesty, how did you think about the development rights in the south of Chang’an when I said before?” Thinking of this, Zhao Feng opened his mouth and asked Li Shimin beside him. _
