Gu Jiu was also very curious. Could it be that anyone else knew the use of limestone?

Su Nanxing and Gu Jingmo were certain that they were the only ones who knew the uses of limestone.

As for whether there would be a third person traveling through time, the system said it was impossible.

Each small world will only have one system, and without a system, people cannot travel through it.

Su Nanxing was able to travel through time because of Gu Jingmo.

Therefore, there will not be a third time traveler in this world.

If this possibility is ruled out, then the only possibility is that there is someone around the two of them who leaked the information.

Su Nanxing first began to think about the people around him, "After I read the formula you gave me, I put it in the space.

Furthermore, those men in black are so powerful. The people around me are just ordinary people and shouldn’t have such great power.”

The most powerful person he could come into contact with was the county magistrate.

However, the Xuanyuan County Magistrate was Gu Jingmo's man, and he had no intention of hiding the fact that he was going to open a cement factory from him.

Gu Jingmo lowered his head and thought, "I don't have many confidants on the other side of the border.

It seems that this news was most likely leaked by someone on my side."

Su Nanxing originally thought that the border was full of Prince Zhennan's men, so Gu Jingmo would be safer.

But now when I listen to it, it doesn’t seem to be the case.

"Are there any candidates you doubt?" Su Nanxing asked.

Gu Jingmo nodded, "On the border, the only people who dare to oppose our Zhennan Palace are people from the enemy country and the Baili family."

"The Baili family?" Su Nanxing had heard of it. It was a family of weapons. "Is it the Baili family that's so good at making weapons?"

Gu Jingmo: "Yes, the Baili family has been rooted in the border since the previous dynasty, and their control over the border is even stronger than our Zhennan Palace.

Fortunately, my father had a good relationship with the head of the Baili family, which allowed him to take control of Qingzhou more quickly."

"So this incident was done by the Baili family?" Su Nanxing didn't understand, "But why did they do this?

If you want to steal our business, you should steal the formula."

Gu Jingmo had some guesses in his mind, "Leave this matter to me. I will arrange the cement factory before I leave.

Just prepare the cement and build houses for the village."

Su Nanxing nodded, "Okay, then I'll leave the cement factory matters to you."

Gu Jingmo acted quickly. Not far from where the limestone was found, a group of people soon came and started building a workshop.

The Xuanyuan County Magistrate personally supervised the construction, and there were soldiers guarding the area.

Anyone who wants to steal the limestone this time will definitely never come back.

Su Nanxing was the first to order cement, as the villagers didn't know what cement was.

But the eldest grandson of the Su family said that it can be used to build a house, so there must be no problem.

Not to mention, this cement factory is very mysterious. It is said that it was built under the personal supervision of the county magistrate.

There must be good stuff in it. The fact that Taohua Village can use it is also thanks to Su Nanxing.

Now many people want to place orders because they know that it is an official workshop led by the county magistrate.

As a result, there was no longer a queue. The Xuanyuan County Magistrate said that the cement produced now would be sent to the border first.

If people in the city want to buy it, they have to wait at least half a year.

So Taohua Village became the only folk village where cement could be purchased.

It can be said that everyone in Nanqing City is paying attention to the construction of houses in Taohua Village.

Everyone wants to see what this cement is.
