It's just that the cave is dry and not ventilated, and people can't live in the cave for a long time.

However, Tang Jingyun didn't need these people to live in the cave for a long time.

When the house is erected and the fence is built, these people can move out one after another.

Moreover, Tang Jingyun is ready to build this base well and create a truly impregnable fortress!

Tang Jingyun drew modern brick houses with bricks and tiles as the main material, and then wrote out the production process of bricks and tiles, and by the way, even the production formula of cement was made.

The raw materials for Portland cement clinker are mainly calcareous raw materials, clay raw materials, correction raw materials, in addition, only need to add some auxiliary materials and retarders according to the specific production situation.

Limestone raw materials, limestone, shells, etc. are fine.

Clay raw materials to find some clay, loess, river mud.

There are many correction raw materials, what pyrite slag (iron powder), iron ore, copper slag, what river sand, sandstone, siltstone, diatomaceous earth, as well as slag, gangue, bauxite, etc., which can be used for convenience.

And the reason why Tang Jingyun dared to mention this matter was because there were several high-speed rail mines in the county next door, and there were countless slags produced every day, and not only most people avoided it, but no one wanted it.

If Tang Jingyun sent someone to take away the slag from the mountains, maybe even the county officials, ahh The county magistrate will come over to thank her.

This simply created natural convenience for Tang Jingyun, and the most difficult material to find to make cement arrived in Tang Jingyun's hands so easily.

However, Tang Jingyun is not ready to pull slag for the time being, and the most important thing at present is the exam of Zhao Xiaozhou and Xie Zhaojun.

Tang Jingyun asked people to make more than a dozen wide beds in the cave, transplanted some beast repellent grass and placed them in a few corners, and let those who had a lot of strength make a door with a wooden board and install it at the entrance of the cave.

The solid wood door is extremely heavy, and it seems a little difficult for two adults to push, and there are two huge stones outside the door that connect to the mouth of the cave, and when they rest in the middle of the night, they will be moved by people to the place directly opposite the entrance of the cave, blocking most of the gaps.

Moreover, Tang Jingyun also asked people to wipe the wooden door with water mixed with animal repellent grass powder every few days, which basically guaranteed the people in the cave.

Now that time is urgent, Tang Jingyun can only make these arrangements, and other plans can only wait for her to come back from Fucheng.

Leaving a sum of supplies, Tang Jingyun and the others returned to the county seat.

Zhao Xiaozhou's farm is remote and desolate, not to mention that it is half a day's journey from the county seat.

Therefore, in the mountains outside, they develop as much wasteland as they want.

Whether in ancient or modern China, the vast majority of people have an inexplicable and deep love for the land, so Zhao Xiaozhou's farm can use much more land than Tang Jingyun imagined.

How to use these lands, Tang Jingyun was still thinking about this problem on the way back to the city.

"When will you and Xie Zhaojun leave for Fucheng?" Tang Jingyun asked.

"It's either tomorrow or the day after tomorrow, if you go early, you can grab a good yard to live in, and if it's late, I guess I won't even have to choose an inn." Zhao Xiaozhou replied.

Actually, where he wants to live, Zhao Dakui and they have already prepared, but these words are not easy to say.

enmmm…… It should be difficult to tell Tang Jingyun.

Zhao Xiaozhou touched his nose and added thoughtfully: "However, I have a friend in Fucheng, I can write to him to rent a yard for me first, and we can just go and move in." ”

Tang Jingyun didn't suspect anything and nodded.

But she was thinking about whether to take Tang Xiuyue with her, and if she didn't, she would rest assured where to put the person.

"Aunt Zhao won't go, Xiaoyue can also stay with Aunt Zhao." Zhao Xiaozhou saw Tang Jingyun's embarrassment and spoke again.

At this time, Xie Zhaojun and Xie Linxing had already moved out of Zhao Xiaozhou's yard, but moved to the store like those workers.

This is also to avoid suspicion, and Zhao Xiaozhou considers that he and Uncle Dakui are going to take the exam in the county seat soon, if Xie Linxing is allowed to live again, it will ruin Aunt Zhao's reputation at that time.

However, it was Xie Linxing who took the initiative to bring it up.

And since the grandson works in other people's shops, he should also abide by the rules, and there is no special treatment.

Of course, the most important thing is for the sake of Zhao Niangzi's reputation.

When Tang Jingyun and the others left for Fucheng, Tang Jingyun received another call from Li Yu.

Li Yu found his father.

At that time, his father was already dying, and if he hadn't gone in time, he was afraid that he would be separated from his father forever in this life.

This is all thanks to the beast repellent grass that Tang Jingyun traded to him.

It was worthy of being a third-level thing, even a sixth-level spirit beast would run away in a panic when it saw him from a distance, and it also allowed him to take his unconscious father out of the mountain range smoothly, for which he specially came to thank Tang Jingyun.

Tang Jingyun learned that the beast repellent grass could help Li Yu, and he was naturally very happy.

However, he still reminded him that those were spirit beasts after all, different from the ordinary beasts in her world, and they still couldn't completely rely on the beast repellent grass in the future.

Li Yu thanked her for her kindness and said that he understood.

With this beast repellent grass, Li Yu made a fortune in his world.

Because, the ferocity of spirit animals is often an obstacle to their search for spirit plants.

With the beast repellent grass, the safety factor rises in a straight line, and walking in the mountains, such as entering a no-man's land, picking spirit plants is very safe and smooth.

Li Yu also knows the truth of his guilt.

When he had made enough money, he took the initiative to give the seeds of the beast repellent grass to his father and let him hand them over to the family.

The status and treatment of the father and son in the family soon improved significantly, and it was much better than before.

How Li Yu is, Tang Jingyun naturally doesn't know.

After Zhao Xiaozhou and the others were ready, Zhao Dakui drove the ox cart and sent Tang Jingyun and them to Fucheng.

At this time, Zhao Xiaozhou's dilapidated and desolate farm also officially began to collect materials and prepare for construction.

The draft drawing given by Tang Jingyun was handed over by Zhao Xiaozhou to a professional craftsman for viewing, and after careful planning and revision again, Zhao Xiaozhou received the final engineering defense map.

This kind of arming map was a new type of arming map that he had never seen before, but it attracted more attention than ever.

In ancient times, houses were basically built of wood, and the walls were built either with rotten thatch mixed with clay, or wooden fences.

It is too wasteful of manpower and material resources to pile up stones.

Moreover, there are no crane pulleys and plank road carts, and they all rely on manpower, and they want to build tall walls, and they are completely black-hearted landlords.
