Douluo: Make a gun first

Chapter 162: The King of Infrastructure, Cement is Launched

Niu Gao may seem rough, but in fact, to become the clan leader, one must not only have strong strength. If he is brainless, he will definitely lead the family to disaster.

Especially since they have experienced betrayal before, it would be impossible to convince them if we just make empty promises.

Of course, Shen Feng also understood this truth. He smiled slightly, stood up from his seat and walked to the center of the hall.

"Senior Niu Gao, the purpose of our Soul Hunter Guild is to proceed from reality in everything, reject false, grand, and empty idealism, unite all forces that can be united, promote the common values ​​of peaceful development, fairness, justice, democracy and freedom for all mankind, and then persist in creating a friendly social environment of win-win cooperation, mutual benefit, and common progress."

"So in order to further our friendly cooperation, the boy naturally came with sincerity."

As he spoke, Shen Feng waved his hand and released four rectangular gray-white stones from his wristband, which smashed heavily on the floor of the hall.

Niu Gao was stunned for a moment: "Stone? What do you mean, Young President?"

Shen Feng laughed and said, "Senior Niu Gao, this thing is not as simple as a stone. It is a magical weapon that I found specially for the Yu clan."

"As long as you master this, I can guarantee that the Yu clan will last for a hundred years and prosper forever."

Niu Gao's expression changed slightly, and he looked back and forth between Shen Feng and the stone with a scrutinizing gaze. He said in disbelief, "Could it be that the Young President is framing me? It's just a small stone?"

"Although the stone you took out is smoother and flatter, it's not something special."

"As for smooth stones like this, we in the Yu clan can't say that we can find them everywhere, but there are quite a few of them. As long as we spend some time polishing them, we can always polish them. How can it be called a divine weapon of our Yu clan?"

Shen Feng shook his head and smiled, "Senior Niu Gao, I've already told you that this thing is not a stone. You'll understand once you get a closer look."

Niu Gao looked at Shen Feng in confusion, slowly stood up and walked closer, carefully examining the stone that Shen Feng had taken out.

"what?"

With a slight exclamation, Niu Gao, who had been dealing with various building materials for many years, quickly discovered the difference.

The stones in front of us looked like they were cast in one piece, not like they were mined from boulders and then polished smooth.

Moreover, there are a few bubble pits on the surface of these grayish-white stones, which further proves that these stones are artificially cast, not naturally formed.

Reaching out and touching the smooth surface of the stone, Niu Gao used all five fingers and exerted 30% of his strength before he successfully broke off a corner of the stone.

"Is this made of crushed stones glued together?"

When Niu Gao saw the inside of the stone, he was obviously surprised.

As far as he knew, there were artificial bricks and stones, but they were just mud bricks made by civilians using clay mixed with grass and wood.

Those with higher costs will use pure clay to make brick blanks, which are then dried in the shade and fired in a cave for 8-15 days to form blue bricks or red bricks that are as hard as stone.

Mud bricks have low strength and are mostly used for building civilian houses. They can also be used for emergency repairs of city walls in small cities during wartime.

Blue bricks and red bricks are slightly stronger, but they are expensive and take up to a month to build, so they are mostly used by small nobles to build manors and construct city walls of medium-sized cities.

As for the great nobles and large cities, they could no longer be built with these artificial bricks and stones which were inferior in strength to natural stones.

Moreover, the greater the nobility and the larger the city, the more precious and harder the natural stone used was.

But the artificial stone that Shen Feng brought out, without being tempered by fire, was actually harder than all the artificial bricks and stones available today, and was even not inferior to the strength of most natural stones. Niu Gao nodded with satisfaction: "Yes, this artificial brick and stone has a very good hardness and can be used to build any city wall except the Royal City and the Imperial City."

"I just don't know how much this kind of brick and stone costs. If it's too expensive, or takes too long, or is too complicated to make, then maybe it's better to just mine rocks nearby."

Shen Feng smiled and shook his head: "Senior Niu Gao is worrying too much. Since I took this thing out, it proves that this thing has a crushing advantage over stone."

"It only takes 30 days from production to shaping and then to the current strength. In 3 days, it can reach 4% of its current strength, and in 7 days it can reach 6%."

Niu Gao's pupils suddenly contracted: "Are you serious? If so, then the time for repairing and reinforcing the city wall during the war can be greatly shortened."

"In a battlefield where military situations are urgent, being able to quickly repair the city wall can definitely influence the outcome of a crucial battle."

As expected of a big shot in the construction industry, Shen Feng simply introduced the production time of this new material, and Niu Gao immediately linked it to the repair of the city wall.

Shen Feng nodded and said confidently, "Moreover, this thing is not just about high hardness and fast construction. Its toughness can definitely crush all natural stones in the world."

"Compared with all the building materials of the same era, mine is definitely a product of the times."

Niu Gao was stunned. Toughness? This was the first time he heard a new term about stone.

When did the word toughness become applicable to hard stone?
Aren't all stones classified according to their hardness?
If the stone is tough, how do they mine it? Cut it with a knife? Saw it?
Shen Feng smiled as he looked at the confused Niu Gao, then stretched out his hand and made a gesture of invitation.

"If you don't believe me, you can try it yourself."

Niu Gao looked at Shen Feng doubtfully, then he bulged the muscles in his right hand and slammed it hard on the stone on the ground.

With a loud bang, the stones brought by Shen Feng cracked, but did not break completely. It was as if there was something mixed in it, which created the effect of a lingering connection.

Niu Gao frowned slightly, gathered his soul power and exerted force again, directly shattering the surface attachments and revealing the delicate core part inside.

"Is this bamboo?"

Shen Feng nodded: "Yes, to be precise, it is shade-dried bamboo."

"The crushed stone and adhesive on the outside provide the rigidity, while the bamboo on the inside provides the toughness."

"The strength of the outside protects the softness of the inside, while the softness of the inside pulls at the strength of the inside, just like a sharp blade forged by the steel-cladding method. It is strong on the outside and soft on the inside, ultimately creating this new type of artificial masonry."

"Senior, please think about it. If we use this new material I provided to build a complete city wall cast in one piece, can its sturdiness reach the highest level in the world?"

As he spoke, Shen Feng took out a square city model from his wristband and placed it on the ground. Then he took out a bag of cement and a bundle of split bamboo strips and replicated step by step the entire process of pouring an integrated city wall with concrete.

Niu Gao was shocked, completely shocked. Not only did Shen Feng perfectly integrate the forging skills into artificial building materials, he even cast an integrated city wall like casting.

This advanced concept and brain-opening idea instantly made Niu Gao's mind burst with countless new sparks.

Buildings, secret passages, and mechanisms that were previously impossible to build due to material limitations, now seem to no longer be a problem for him.

"This thing, what is the name of this thing?"

Shen Feng said with the confidence of a modern man: "This thing is called concrete, it can also be called artificial stone, but I still like to call it just 'concrete'."
