Song Yunshu thought that there was very little iron, but she didn't expect a lot, their manpower was not enough at all, besides, she took a look, such iron, with their current people, they couldn't carry it back.

"Otherwise, I'll go back to the capital first and find some people to come over." Chu Yuchen felt that it was not a way to go on like this, and several people were completely unable to deal with it here.

Song Yunshu felt the same, but if she was the only one here, she would inevitably be a little worried.

"If you leave, I'm afraid I can't do anything here."

She sighed, there was so much pig iron here, and she was still worried about what would happen if others found out.

Chu Yuchen took a look, their actions were so hidden, they should be fine, and no one was interested in iron now.

He thought that he would come back soon, and it would be okay to let Song Yunshu wait here a little longer.

"You're waiting for me here, don't worry, I'll be back soon."

He calculated the time it would take for him to go back and forth, and it was not very far from the capital, as long as the horse was a little faster, it would take seven days to get there.

Song Yunshu also had no choice, and he couldn't drag it out, so he had to let Chu Yuchen leave.

"Then you can go, come back quickly."

Seeing the iron being dug out little by little, she also had an indescribable feeling in her heart, not knowing if it was because she got rich or because of what.

Chu Yuchen nodded, brought a little iron back to the capital, and soon, brought a large number of people here.

In order to conceal himself, he couldn't bring too many people, otherwise, others would be suspicious, and besides, they couldn't move too much.

Song Yunshu looked at the manpower and it was almost like this, and they didn't dare to make a big noise.

"There's too much iron here, or we'll take a little bit first, and put the rest here and wait for the next batch to get it."

Chu Yuchen felt that it was almost enough, he couldn't be so greedy, and he took back so much at once, and they didn't know how to place it.

Song Yunshu thought about it, since they are all here, it is better to take them all, besides, leave a little bit here, if someone finds out, they may find them too.

It's better to hollow out this place directly, and even if others find it, they won't know that there is iron here.

"It's all here, it's better to dig up this place, and leave a little bit of what if they find the suspicion on us."

She thought that since everything was kept secret, it was better to be thorough.

Chu Yuchen felt that it was also good, if those people were interested, it would not be good to suspect them.

"You're still smart, so let's dig it up."

He looked at so much iron that he didn't know how long he was going to dig.

Those people are also continuing to dig, because there is no advanced technology, digging is very slow, although there are many people, but the efficiency has not been high.

Song Yunshu was a little anxious, if it was in modern times, it would have been good a long time ago, and she was a little unaccustomed to it.

Since the ancients were also wise, she thought that it would be better to rely on the wisdom of the ancients to solve this problem.

"Let's make a simple device that can dig this thing."

She thought about what a modern excavator looks like, so she found a few things and put them together, as if they really looked like that, but they were really too bad.

Chu Yuchen didn't know what Song Yunshu wanted to do, he looked at it, this thing was very novel to him.

"What is this, I've never seen it before."

He picked it up, dug it in, and felt much more efficient with their little shovels.

Song Yunshu didn't explain, just asked him to try this thing, not to mention, this thing is indeed a lot more efficient.

She made a few more and distributed them to the people, who felt that it was also very labor-saving.

"I really didn't expect that there would be such a good thing, what do you think?"

Chu Yuchen was a little admired, how could he not have imagined it, he had been in a hundred battles for so many years, and he didn't know how to be opportunistic.

Song Yunshu smiled, if Chu Yuchen was in the modern era, he would know what this was all about, and it was too different from the modern one.

But as long as it works, she can't think too much about it for just a little time.

"It's nothing, let's dig it quickly, I think this thing will be dug for a long time, we have to fight quickly, and we can't let others find out."

Song Yunshu looked at the sky, they didn't know how much time they had been digging, they had been busy with this thing all day, if they didn't go back earlier, others would be suspicious.

Yang Yunlong felt a little tired and wanted to take a break, so he sat on the ground, and so did Song Yunshu, who had been digging for a whole day and wanted to take a break.

"Do you have a good way to fix this thing quickly?"

Yang Yunlong still felt that the efficiency was too low, and there was too much iron.

Song Yunshu thought about it, according to the modern method, it won't work here, there are too few things here, they can only rely on the ancient method.

She looked at it and could only do this for the time being, after all, she didn't know much about it.

"I think so, let's do this for the time being, there will definitely be a way to do it then."

Yang Yunlong nodded, along the way, she also taught herself a lot of this knowledge, and also broadened his knowledge.

After that, Song Yunshu and Chu Yuchen studied the problem of larvae here.

The two of them waited for this for a long time, and the larvae were full of curiosity for Song Yunshu.

"What kind of creature do you think this creature is of any use to us?"

She hadn't seen this thing yet, and in modern times, this kind of thing is too rare.

Chu Yuchen is not very clear, he rarely studies this.

"Let's see, I don't know exactly how this came about."

He looked closely, but still couldn't see anything.

Song Yunshu was very helpless, since this was the case, he had to wait, the period of larval development was also very long, although he didn't know when the larvae would be able to grow up, but one day, the mystery would definitely surface.

"I'll have to wait."

There is no mention of this thing in the book, so it can be said that I don't know what the larvae look like when they grow up.

"The larvae haven't grown yet, so maybe it's going to take a long time."

Song Yunshu looked at the larvae for a while, not knowing when they would be able to break out of the cocoon.

Chu Yuchen looked at it, anyway, it seemed that this iron would not be able to be dug in a short time, and there was just time to observe the larvae more.

At this time, Shadow Thirteen was also looking for the production cycle of the burial beetle, and for this, he read a lot of information, but still didn't find it.

He looked at the immobile larva, trying to open him to see if there was any mystery, but after thinking about it, he thought that it was better to wait, and finally, the effort paid off, and after three months, he finally waited for the first larva, which gave him a lot of confidence.

"I've been waiting for you."

He looked at the larva with an indescribable sense of pride.
