"Yue'er, this is?"

Murong Li was so surprised when he saw this scene, it couldn't be what he thought, right?

Su Yue shook his head: "I don't know what it is, I only found it in the afternoon, there is a tunnel below here, leading directly to the bottom of the Cloud Mountain Range, I walked for an hour in the afternoon and didn't come to the end, and then I came back." Let's go tonight and see if it leads to the other side of the mountain?"

Murong Li nodded hurriedly and hurriedly followed Su Yue into the tunnel.

This section of the tunnel Su Yue walked through during the day and cleaned it up, and there were no poisonous snakes and poisonous insects.

Behind this tunnel, there were more poisonous snakes and poisonous insects, and the two cooperated, Murong Li used his internal force to sprinkle poison in front, and Su Yue put away all the poisonous snakes and poisonous insects that were poisoned.

In this way, when it was almost dawn, they could smell the smell of the sea in the cave, and their eyes lit up, and sure enough, as they thought, this side was the other side of the Cloud Mountains.

Murong Li swept away the exhaustion on his body, he excitedly pulled Su Yue to run, and the two ran out of the cave in one go.

What they saw was the sea, and the sound of the sea crashing against the reef was like a fairy sound in the ears of the two of them at this moment.

Su Yue's spiritual power glanced at this exit, and the exit was on a very large reef, even if the tide was high, the sea water could not come up.

Murong Li ran to the edge of the reef and looked around, thinking in his heart.

Su Yue is also looking at this reef, if he makes salt on it, it will save a lot of trouble.

Salt production is bound to use people, and someone has to build a house here, Su Yue looks at the rock wall, and he can chisel a stone house there......

Su Yue looked at it, and suddenly remembered a question, who is the one who opened up this tunnel?

Because she found that there was no trace of salt here, and she thought that the purpose of opening the tunnel was the same as her.

After a circle, there was no trace of human error, except for the mouth of the cave.

Su Yue was shocked, thinking that this side belonged to the territory of the Beifeng Kingdom, if it was ......

What if this tunnel was not fought by the people of Xifeng Kingdom, but by the female cadres of Beifeng Kingdom?

And if the army of the Beifeng Kingdom came to the Xifeng Kingdom from the tunnel and was caught off guard by the Xifeng Kingdom, the Xifeng Kingdom is estimated to be destroyed by then, and I don't know how the Xifeng Kingdom will perish at that time.

Thinking of this, Su Yue's heart sank, and she walked over to Murong Li, who was excited.

"What's wrong?" Murong Li asked.

Su Yue pointed here and asked, "Didn't you find this tunnel unusual?"

Murong Li was stunned for a moment, he seemed to have thought of something, the smile on his face was closed, and he looked here very seriously.

Although there is a sea here, there is also a coastline, so what kind of place will it be if you go out along the coastline?

If the army of the North Wind Country wants to attack the Xifeng Kingdom, they don't need to use a boat to cross the ocean, they come directly along the coastline and enter the Xifeng Kingdom through this tunnel, what kind of consequences will it be?

Murong Li's face froze suddenly, and he felt a chill in his heart.

"Yue'er, let's go back quickly, and immediately call someone over to check on it and see what the situation is over there."

Su Yue's expression was also heavy: "You should check it, at least you have to take precautions, this tunnel looks like it hasn't been used for a long time, and it doesn't guarantee that the people of Beifeng Kingdom won't know about the existence of this tunnel."

It is possible that the people who fought this tunnel were exterminated, and this tunnel was deserted here, or it was possible that the conditions for the Northern Phoenix Kingdom to attack the Western Phoenix Kingdom were not yet ripe.

But there is one thing that must be checked, the people or the scale of the people who open up this tunnel are not ordinary people can do, and it is impossible for one person to get through.

And I heard that Yunwu Village has been here for a long time, hundreds of years ago, and no one in the village knows about it?

"Well, what Yue'er said makes sense, I was overjoyed just now and ignored it." Murong Li said reproachfully.

As soon as he came out, it felt a little wrong, but as soon as the feeling passed, he didn't think about it deeply.

Now that I think about it, it's scary.

The inaction of the royal family of Xifeng Kingdom does not mean that he is willing to see other countries invade Xifeng

Fengguo.

Murong Li hugged Su Yue, he was very glad to have come to Cloud Village, and he was very glad that Yue'er had discovered this tunnel.

He felt that Su Yue was his lucky star, and since he intersected with her, his whole life had been changing.

The journey back was very fast, and for fear of being discovered, Murong Li carried Su Yue on his back and went back directly with light skills, and it took an hour.

When the two arrived, the construction site was already in full swing.

The two of them quietly went out of the cellar and went back from another place.

Su Qiwen's brothers were not there, Su Yue and the two simply ate a little food, Murong left to help, and Su Yue distributed food and tinkered with things at home.

After two days, the foundation will be laid.

Before laying the foundation, Su Yue's cement had not been successful.

The gluing paste used to build a house here is made of glutinous rice, and this year's drought is hard, not to mention that the cost is too expensive, so Su Yue thought of using cement to build a house.

If the cement is pounded out by her, it will not only be used to build houses, but also to build roads, and the cost of this thing is low.

If you want to get rich, you will build roads first, and then Xifeng will all build cement roads that extend in all directions, which is convenient for travel and transportation, and it will be made of salt in the future, and it also needs to be sold.

Roads across the country have been built, and there is no problem of inconvenient transportation.

The books in the study can be said to be all-inclusive, and it is not too convenient for Su Yue to find a way to make cement.

After finding it, she told Murong Li that he raised his hands in favor of such things that would benefit the country and the people, so he helped with errands, and he would provide whatever Su Yue wanted.

Two days later, the two finally came up with cement.

It's just that the effect is not very good, maybe it's because of the material, maybe it's because of the imbalance in the ratio, the two simply suspended the villagers on the construction site to help cut down the trees, and they let go of it.

The foundation pit on the construction site has been dug out, just waiting to lay the foundation.

Although the villagers who came to help did not know why they stopped, they assured them that they would have food, and the owner told them to do whatever they wanted.

After that, the two continued to experiment.

After another three days, the usable cement was finally concocted.

The two were overjoyed, and Murong Li immediately arranged for someone to buy materials, limestone, the main material of cement, which is quite a bit in Northwest County.

The materials bought were pulled directly to the construction site, and Murong Li operated them personally.

When the villagers saw him pouring mud into the foundation, they were puzzled and shook their heads, saying that he was coming from nonsense.

When Luo Dinghe heard about this, he threw down the carpentry work in his hand and ran to the construction site, and watched Murong Li work carefully.

"Miss Su, are you sure this mud slurry is dry and unusual?" Luo Dinghe had never seen such a thing, let alone heard of it.

If the effect of this mud slurry is better than that of glutinous rice slurry, then this is a great invention.
