Midday.

Win Changsheng and Brother Zheng ate shabu mutton together.

Tastes good.

After Ying Changsheng ate and drank, he stroked his little belly, and couldn't help but say secretly in his heart.

You can't be greedy in the future.

You have to pay attention to your figure!

And Brother Zheng, just after he was full, he had to deal with government affairs.

For such a huge empire as Great Qin.

Almost every day, there are countless state affairs that need to be dealt with.

So, now.

After a short break, he had to deal with government affairs.

Of course, before he left, he didn't forget to take away the globe he got from Ying Changsheng.

For Brother Zheng.

It's still a bit of fun.

In particular, it can allow him to gain a lot of knowledge.

After all, in the eyes of the original political brother.

It's all under heaven.

That's how big it is.

Great Qin has occupied most of the known world.

But now, after learning about this globe.

Brother Zheng realized this.

This world is bigger than he imagined!

After Win Changsheng was full, he was idle, so he said to Brother Zheng.

"Father, will your sons go over with you to review the folds?"

"You kid, when you were in charge of the country, you didn't handle government affairs well, but now it's okay, you're not in charge of the country, but you have the heart to follow me to deal with state affairs?"

Ying Zheng chuckled a few times, but nevertheless, agreed to Ying Changsheng's request.

With him, he arrived at Zhangtai Palace.

Then, in the temple.

I saw that Brother Zheng picked it up, and there was a paper fold on the table.

Then, I opened it and looked at it.

And Win Changsheng said that he was here to accompany Brother Zheng and review the folds.

But when he came, he looked east and west.

Obviously, there is no idea of dealing with government affairs.

However, Ying Zheng did not take this to heart.

After all, he didn't expect that after Win Changsheng came over, he would handle state affairs for him.

In Brother Zheng's opinion.

Win Changsheng, this kid, after coming over, it's good enough not to make trouble for yourself.

That's when it happened.

Win Zheng, suddenly raised his eyebrows.

put down the fold in his hand, and slammed the royal case.

"Father, what are you?"

Ying Changsheng hurriedly looked at Ying Zheng, only to see that Ying Zheng frowned.

For a moment, he couldn't help but be a little flustered.

Heartway.

Could it be that we are here, which has made Brother Zheng dissatisfied?

No, you have to get out of the way.

Thinking in his heart, Win Changsheng will take a short step and slip away.

At this time, Brother Zheng sighed and said.

"This gallop, how can it be so easy to go wrong!"

Chi Dao?

Hearing this, Ying Changsheng understood.

Brother Zheng was angry and had nothing to do with him, so he couldn't help but step forward and ask with a frown.

"Is my father angry because of the matter of Chi Dao?"

"That's right!"

Ying Zheng sighed.

Immediately, he threw the fold in front of Ying Changsheng.

"You kid, take a look at what is written on this recital!"

Ying Changsheng took the fold, and then, looked at it.

In an instant, he understood the reason why Ying Zheng was so angry.

The reason is actually quite simple.

After the establishment of the Great Qin Empire.

There are several major projects that are world-famous.

Except for the well-known Great Wall.

There is another project that future generations do not know much about.

And this is Daqin's galloping road.

Chidao is a road built by Daqin.

It has penetrated the world of Daqin, every county and county.

These roads can be called the Daqin version of the highway.

In such an era when productivity is extremely backward.

To be able to build such a gallop road.

For Da Qin, it took a lot of effort.

The problem, however, is this.

The current Great Qin, although successful, built the Chi Road.

But.

Here's the problem.

Gallop this thing.

After all, it's just a dirt road!

The highway of later generations, reinforced concrete.

What a good thing.

built out of the highway.

It's still going to be bad.

What's more, it's Daqin's gallop?

It's not, the current gallop, there is a problem.

The magistrates reported that it was several gallop roads, badly damaged, and in need of repairs.

And this matter made Brother Zheng embarrassed.

After all, at the beginning, it had already taken a lot of effort to repair these gallop roads.

Now, it's been rebuilt.

How much work it takes.

How much money and food are wasted?

However, looking at Brother Zheng, his brows were tightly locked.

Win Changsheng, but said with a smile.

"Father, the son has an idea!"

"Oh, you kid, what's your idea?"

Ying Zheng looked at Ying Changsheng in surprise.

And winning immortality is the way.

"Father, the son has a way to build the road, and the road that is built is exceptionally strong, and it will not be damaged for decades, or even a hundred years!"

"This, how is this possible?"

Winning politics is incredible, but winning longevity is the way.

"Of course it's possible, the method of the father and the son is actually very simple, it is nothing more than using a new material, this material, compared with the usual, uses a lot of manpower to ram the earth to build the road, which is much easier, and the road built is much stronger......"

"Cement, I've never heard of it!"

Ying Zheng muttered.

"This is a new invention that Erchen has recently researched!"

Win Changsheng explained.

"Today, these are the materials used to build the academy!"

"Oh, I'm really interested!"

Ying Zheng said.

Feels reliable.

He already knew the character of his son.

That is, never empty words, big words.

At this moment, this kid dared to say this so much.

This means that what this kid said is really feasible.

I only heard Brother Zhengdao.

"That's right, I don't want to, after reviewing this piece, I'll go with you to the academy to see what the quality of this so-called cement is, if it's good, I will put this thing into the construction of the road according to your wishes!"

As he spoke, Ying Zheng looked outside and shouted.

"Prepare the horse, I want to leave the palace!"

Not long after, outside the Xianyang Palace.

On the construction site of the college.

Near the academy that was built, when Win Changsheng and Win Zheng appeared, these noble children immediately recognized Win Zheng's identity.

Well, their identity, occasionally, still has the opportunity to see the winner from afar.

At this moment, it is natural to be able to recognize it.

They all knelt on the ground and saluted to win the government.

"Excuse me!"

Win Zheng waved.

Immediately, he looked at the ground.

The ground was unusually strong, as if it were paved with stone slabs.

However, Ying Zheng found that this thing was definitely not paved with stone slabs.

Because, on the top of the stone slab, there will be one piece at a time, but this ground is a whole piece, without the slightest gap.

"That's what you kid said was made of cement?"

Ying Zheng asked Ying Changsheng on the side.

"Yes, this is cement, and when it dries, it is as strong as stone!"

Ying Changsheng nodded and said.

"Someone, get a hammer!"

Ying Zheng waved his hand and said.
