"It's almost time, let's go." Liu Yuan nodded and took the lead in walking out.

Now more than two hours have passed, and the cement has almost solidified, and I have already prepared.

When the group returned to the backyard, Liu Yuan was surprised to find that the guards had been guarding the cement slabs that had been cast, and the five of them were in a circle, holding the horizontal knife in their hands, their eyes wide, and they were about to fight at any time, as if they were guarding a treasure.

This is too exaggerated, this is not worth anything at all, it is simply a big fuss.

After letting these generals retreat, Liu Yuan squatted down, looked at the cement board, the surface was almost solidified, touched it with his hand, it was cold and cold, after more than two hours of solidification, those cement slabs had been formed, but with a finger press, a small finger mark appeared on the cement surface, but this is normal, after all, the solidification time is only more than two hours, and it is not the kind of high-standard special cement, it can be quickly condensed, if you want it to be completely solidified, it will take at least two days.

"Liu Yuan, how is it? No problem, right? Old Demon King Cheng asked with a concerned expression.

Li Jing squatted down, touched the cement slab, and said with a look of surprise: "It is indeed very different from just now, strange." ”

Liu Yuan nodded while a few generals went to inspect and said, "There is no problem, it is more than enough to repair roads." ”

Wei Chi Jingde touched the cement, squinted his small eyes, suddenly pulled out the horizontal knife, and said while chopping: "Try how hard it is." ”

Bang, the treasure knife only slashed into a small half inch and could not enter again, Wei Chi Jingde felt that he slashed hard, as if he was slashing on a stone, the power of his own split. Even the thick wood of the bowl can be split, and because of the excessive force, the horizontal knife and the cement board seem to be sparking.

"Tut-tut, it's amazing, it's much harder than just now, are these just the mixture of sand and stones?" Wei Chi Jingde said in surprise.

Liu Yuan said with certainty: "This is not wrong, Uncle Wei Chi, your guards have been guarding just now, if you don't believe it." You can just ask him. ”

Seeing the inquiring gaze of his master, the general who was in charge of guarding just now hurriedly said: "Master, the little one has been guarding and has never left half a step." ”

You can still believe the words of your own people. Wei Chi Jingde knocked on the cement slab with his hand and said in surprise: "It's amazing." Just some sand and gravel. It seemed like playing with mud, but I didn't expect it to be as hard as a stone, magical, magical. ”

Li Jing's face still showed a look of surprise, but he looked at the finger mark he pressed with his hand and said, "It's really amazing, but." Xiaoyuan, will this hardness be a little worse, Li admitted that it is much harder than just now, if it is used as a road. If an overloaded carriage passed by, wouldn't it be very easy to destroy? ”

Jiang is still old and spicy, these old guys, when they start doing things, one is more cautious than the other, one is more careful than the other, and the problem is immediately found as soon as they are checked.

Liu Yuan did not deny it, nodded and said: "Uncle Li's worries little nephew understands, I just show you how to do it, in fact, these cement slabs have not been completely solidified, from the casting to now, it has only been more than an hour, according to normal terms, it takes two days to wait for it to completely solidify, this is also the reason why the little nephew pours five pieces at a time, when the uncles take a piece back to observe, pour water two or three times a day, splash it on it, and try it again after two days, of course, it has been cast, and the little nephew is also prepared in advance. ”

After speaking, Liu Yuan asked a few subordinates to carry a cement slab that had been cast in the research institute, put it in front of several people, and then made a "please" gesture to everyone.

This is a piece of about one square, about three inches thick cement slab, it takes four big men to lift, Cheng Lao Demon King, Li Zhanshen, Yu Chi Jingde, etc. in a circle, carefully study this cement slab, everyone is pressed, and knocked with their hands, failed to cause damage, the unbelieving Niu Jinda took a punch, the result was naturally covering the injured fist on the side and secretly regretting it, when Yu Chi Jingde cut with the treasure knife again, it was just a shallow trace, a little stronger, all burst out of sparks, and later saw that the treasure knife had a small gap, I was no longer willing to use a knife to cut it.

After tossing for a while, Qin Qiong said in surprise: "Xiaoyuan, you really mixed sand, gravel and cement like this, and there is nothing else in it?" ”

Everyone also looked at Liu Yuan, no one believed it, it was just some sand and stones, stirred up some cement, it was so hard, it was comparable to stone, this is also amazing.

Liu Yuan didn't speak, pulled out a big hammer from the side and gave it to Old Demon King Cheng, and said with a smile: "I heard that Uncle Cheng is infinitely powerful, or if you don't show your second-hand, smash this cement slab open and take a look." ”

"Okay, then I'll try." Old Demon King Cheng just hesitated for a moment, and immediately agreed.

"Let me show you how good I am at Lao Cheng."

After Cheng Lao Demon King finished speaking, he first weighed the weight of the hammer, nodded with satisfaction, took off the coat on his upper body, revealing the sturdy body of Jianzi, with a little force, the fine flesh was protruding, like a devil muscled man, the strong body seemed to contain infinite energy, just standing there, it gave people a sense of majesty and slaughter.

Sui and Tang Dynasty martial arts, that is, scholars and literati, also like to wear a sword, deter Xiaoxiao, historical records, poet immortal Li Bai, is also a master of the sword, Cheng Lao Demon King can start his own name in the era of heroes, that strength is naturally not blown, although I have not seen him go into battle to kill the enemy, see his body, it is already very good.

"Hi" Old Demon King Cheng shouted, raised the hammer high, and then fell heavily on the cement slab, making a muffled sound of "Peng".

"Huh? This thing is pretty sturdy. Seeing that a hammer could not smash the cement slab, Cheng Lao Demon King was a little surprised, this hammer, with a force of thousands of catties, was hit on the stone, but it could not be smashed, and it was also smashed to smash a layer, but this cement slab was so tough.

The famous general is really a famous general, Liu Yuan looked at it from the side, the power of this hammer is too strong, on the battlefield, this hammer smashed on the person's body, that doesn't smash the person into a pulp, this cement slab is more than three inches thick, and it is attached to the ground to unload, if it is thinner, it is estimated that he will be smashed with a hammer.

Wei Chi Jingde pouted and said: "Cheng Laohei, you can't do it, you won't use all your strength on a woman's belly, if not, let the old man come." ”

These words suddenly touched the self-esteem of Cheng Lao Demon King, and he hurriedly said: "Who said that I can't do it, I just warmed up just now, you have to watch it this time." ”

After speaking, I saw him take a deep breath, a little force, the hand holding the hammer burst up pieces of fine meat, a piece of green tendons, and even terrifying, yelling "break", only to see his left foot poked out a step, waist and horse together, both hands forced, the hammer in the air through a beautiful arc, faint with the sound of the wind, "Peng" sound, all of a sudden hit the cement slab.

With a few clicks, the cement block finally couldn't stand the power of Old Demon King Cheng's hammer, and shattered into several pieces at once.

"Good! Old Uncle Cheng is really born with divine power. Liu Yuan couldn't help but praise.

smashed out a hammer with all his strength, and Cheng Lao Demon King's face turned a little red, obviously using too much force, but when he heard Liu Yuan's applause, he was complacent when he heard the words, and he bragged loudly: "Ahem, this little meaning, your Uncle Cheng only used thirty percent of his strength." ”

are all old brothers for so many years, who still doesn't know how many catties and taels they have? That is, Liu Yuan is rare and strange, as soon as the cement slab is smashed open, everyone can't wait to pick it up and see what Litong has.

"Hey, there's nothing special in there."

"Are these sandstones? It's so tightly glued that I can't pinch it open. ”

"It's so the inside."

"It's weird, this one has stones, this one doesn't."

Several people discussed in amazement, this was beyond their understanding, that is, a little sand and gravel, and a pile of gray cement mixed together, there was such a hardness, everyone remembered that at the beginning, it was not much different from mud.

Liu Yuan also picked up a small piece, Kai Shao introduced: "All uncles have seen it, this is the magic cement, at the beginning it is very soft, if you want to be round, if you want to be flat, you can shape it into any shape, after a period of time, it will become very hard, strictly speaking, the hardness is not as good as a solid stone, but it is better than a solid stone, this kind of cement, not afraid of flooding, not afraid of fire, very practical, when you go back, you can also test it." ”

"Of course, this is just researched, and it will be improved in the future, but it is enough to pave the road and build the highway, and you uncles will take this board back first, and think about it, after all, to build a new road, the cost of buying land alone is a huge amount of money, push me to speculate, the money is hundreds of thousands, give me an answer in three days, but first declare that no matter how many uncles participate, construction will start in the near future, and the five uncles together cannot exceed half."

Old Demon King Cheng nodded and said, "Xiaoyuan, your Uncle Cheng believes in you, how much silver do you need, just open your mouth directly, and you will be able to smash the pot and sell iron." ”

"Uncle Cheng, there is no need to be in a hurry to express his position, three days later, we will get together again, and then the people of Qinghe Cui's family will also attend" Liu Yuan said with a straight face: "In business, in addition to testing whether to participate in the business, several uncles also have to consider another issue, that is, this technical problem, all uncles know that this road construction is inseparable from this cement, and this cement is made out by the little nephew with great effort. ”

Wei Chi Jingde squinted his small eyes and said, "Nephew Liu Xian, what is the difference between the two?" ”

"Yes, you can make it clear, what kind of technique is shared, I can hear that Li is also out of the clouds." Li Jing asked curiously. (To be continued......)
