Rumble!

There was a screeching sound on the concrete road, and in an instant, a crack appeared in the corner where it was hammered, but it was only a crack, but it did not crumble.

"Yikes!"

Meng Yi let out a burst of exclamation, his eyes full of disbelief.

He hammered down, others don't know the strength, but he knows very well, the Meng family is the family of the gate, the strength is different from ordinary people, and the Meng family pays attention to exercise, all of them have good physical fitness, plus this hammer weighs more than 100 catties, this hammer down, if it is an ordinary stone, it will definitely be broken and flying.

However, this concrete road is only a crack in the crack, which is completely impossible.

"Try again."

Meng Yi didn't believe in evil, so he made sufficient preparations this time, first picked up the hammer and slashed an arc in the air, quickly attacked, and smashed it down.

Others feel that at least this time the strength must be more than double that of the last time, which is also the greatest power that Meng Yi can emit.

Prosperous!

This time it was louder and had a stronger effect.

After the sound, at first glance, everyone's eyes seemed to shrink, and an incredible surge came to their hearts.

Under such strength, the cement road only cracked a few cracks, but it did not turn into powder as imagined, let alone cracked.

This, this is so peculiar.

It's a miracle that even the hardest rock can shatter with such force, but it doesn't.

At this moment, everyone opened their eyes and moved their eyes to Li Zhao, as if asking how this was done.

Li Zhao squinted and smiled, without saying much, but bent down, knocked down one of the cement blocks with an iron tool, and said to everyone, "What can you see?" ”

Everyone looked at it carefully, but they didn't know what it meant, and they all showed doubts.

Li Zhao knew that everyone hadn't seen it clearly, so he slowly planed a cement block with a short sword, and dug out an object, which was small but extremely tough to see.

He had no intention of stopping, and continued to gouge where he had been smashed, and from time to time it glowed with gold and iron, and after a quarter of an hour, silks and strips were revealed.

"Do you see clearly? That's why the concrete road is so impacted and doesn't break. ”

Li Zhao pointed and said.

"What is this?" Everyone still didn't know what was going on, and Ying Zheng asked.

"This is wrought iron, which Zhao calls steel, and the iron on the bridge, but there is a difference in size."

"This strip of iron is larger, it is the main iron, the main iron plays a supporting role, and the filamentous iron is smaller, but it can implicate the whole road."

Everyone seemed to think of something, showing surprise, Shang Xin asked in surprise: "You mean that the reason why the cement road is not broken is because of this iron." ”

Li Zhao nodded and said: "Exactly, the magnet is mixed with cement, even if it is hammered with a thousand catties, it cannot be completely destroyed, because there is steel, and if it is connected together, I call it a broken thread." ”

"Broken threads? Haha, what a broken thread. Ying Zheng smiled, "It is precisely because of the broken thread that no matter how much strength you have, you can't destroy it, unless you smash the steel, but looking at this iron, it is difficult to destroy it." ”

"Your Majesty" Li Zhao arched his hand, "Exactly, this iron is not comparable to ordinary iron, even if ten thousand people step on it, it will not be damaged in the slightest, and it is suitable for building bridges and paving roads." ”

"It's hard to see if it will be washed away, unless it's seventy years from now." This is not Li Zhaowu's target, the house made of reinforced concrete in the previous life is generally limited to 70 years, which means that in these 70 years, it is difficult to destroy it if there is no external intervention.

"Seventy years, you mean the bridge will last for seventy years?" Ying Zheng was surprised.

You must know that the lifespan of Daqin's wooden bridge is not long, and it is good to last a few years, but this bridge can last for seventy years, what an unbelievable thing!

If this is really the case, wouldn't it be possible to build bridges on the Jingshui and Weishui rivers surrounding Xianyang? In this way, it is difficult for Xianyang not to develop.

This is good news.

Li Zhao nodded affirmatively.

"Haha! God help me Da Qin, haha! Li Zhao, you are very good, and you have made a contribution to my Great Qin. ”

"Congratulations to Your Majesty, congratulations to Your Majesty, if we can have such a bridge, our Daqin will not be afraid of the separation between Jing and Wei, and we will return smoothly." Meng Yi is a civil official, and he naturally exports chapters.

Everyone also congratulated, but they didn't know that the person who should really congratulate was Li Zhao, but Li Zhao didn't care, he smiled, such a merit, as long as the emperor remembered him, he didn't care about others.

"Hahaha!" Ying Zheng was very useful, and he didn't push back everyone's praise, of course, he thought so in his heart, what his son made was Lao Tzu, and it was not wrong for everyone to compliment him.

"Zhao Li Zhao, I saw a strange thing from a vendor just now, called an electric fan, what kind of thing is it?"
