The next day, Yang Yunfei went to check on Yang Xiaolong's injuries early in the morning and found that the wounds were already beginning to heal. It's just that it will be a few days before he is truly healed, and during this time, he will not be able to do anything.

Therefore, his main energy is to build the city wall that blocks the valley, and the second is to find more animal blood genes for Rhubarb, and constantly give Rhubarb suggestions for the modification and improvement of the Demon King Dragon. Of course, it won't take much time, Yang Yunfei only needs to scan it with the attribute panel, and he can get the answer immediately.

Because the lime burning was all done by the Panda Village Chief, his main job was to collect stones and polish them to a little smoother, so that they could at least be stacked evenly and not fall over.

This is the standard that Yang Yunfei set for himself.

"Fortunately, there is Liu Qiming's knife, this kind of knife should also be made of what alloy, not only is it extremely sharp and cutting stones like cutting tofu, but it also doesn't feel heavy at all. It can be used to chop stones. Yang Yunfei carried a knife and stood in front of a hill full of cyan stones, muttering to himself.

Although he and Liu Qiming, a human being, are also in a cooperative relationship at present, he will not return these good things, since they have fallen into his hands, they are his.

Something as dangerous and useful as this is best kept in your own hands, which is both worry-free and safe.

"Let's get started."

Yang Yunfei burst out with a force of up to 6.2 points, and stabbed it on the hard bluestone, and the entire knife was instantly submerged. Then he grabbed the handle of the knife with his two claws and cut it downward, and a gap appeared.

Because the length of this knife is limited, the total length is only about one meter, so the gap in the cut stone is only about one meter. As a result, he couldn't cut a large piece of stone in an instant, so he had to take his time and cut those obvious protruding parts first. Finally, let's take a break.

The work of mining stones is not complicated, it is completely a hard work, and it is only necessary to pay attention to the process of mining and not to keep killing one place, because it will cause the mountain to collapse.

Therefore, after he finished digging one place, he changed the next place and rotated. In this way, the stones on the hill are mined.

Because the most important thing Yang Yunfei lacks now is strength, even if the tools are extremely simple and lacking, his mining speed is not slow.

While Yang Yunfei was mining stones, more than 70 pandas were mobilized and began to dig foundations at the entrance of the valley. This is also a very important work in the construction of the city wall, if the foundation is not dug well, the built city wall will easily collapse, and it will not be able to resist the impact.

It's just that the tools used by these pandas are very simple, all of them are a kind of wood that has been sharpened and flattened at one end. Therefore they are also slow to dig trenches, and there is no way to do it, who told them that they don't even have the most ordinary iron tools now. You can only use the simplest of tools.

Seven days later, Yang Yunfei had mined more than 100 stones, and the length and width of these stones were generally about one meter.

At the same time, these stones were also ordered by Yang Yunfei to be transported to the entrance of the valley by rolling logs. And these pandas have nothing else, but they have a lot of strength, which is the most suitable for this kind of hard work.

With the completion of the stone mining work, Yang Yunfei also joined in the trenching project, and suddenly the pandas dug the trench many times faster.

Of course, there is a strong factor in Yang Yunfei's strength, but more importantly, his knife plays a huge role. At the very least, he could cut off the hard earth and break the rocks into pieces, which saved a lot of effort.

After another five days of this, a ditch seven or eight meters deep appeared. The next step was to put the stones in and glue them together with lime, and the progress of the work was not slow.

In just five days, a wall about ten meters high was erected.

And when the city wall was really built, Yang Yunfei also carved "Panda Valley" on the city wall, four big characters. Not for anything else, just to bring out the momentum.

"Today is a good day, because from today onwards, this valley finally belongs to us Panda, and we will be the sole owners of Panda Valley. No other beast will enter the valley and threaten our lives. ”

Yang Yunfei stood on the city wall, condescendingly looked down at the pandas below, and announced loudly: "This credit belongs to all of us, and from this day on, our pandas have officially entered a new era, that is, the era of the city-state." We pandas are no longer a group of ordinary animals, but a civilization that truly belongs to us, and we are also civilized bears. ”

Although this panda valley is still far away from the real city, and the number of pandas in the valley is only more than a hundred, it already has the most basic conditions for a city.

It was a fresh beginning and another sign of the emergence of the early state.

"Everyone has worked hard during this time, so I decided to take out all the delicious things today and treat everyone."

"yes."

As soon as they heard that there was something delicious, all the pandas instantly cheered up, and even those pandas who were tired of lying down jumped up from the ground.

The power of food is terrifying.

On this day, the pandas are all in a carnival, and all of them are spent eating and drinking. However, not all pandas can relax like this, and some of them are still holding their posts, that is, the members of the Dragon Slayer Team and the Panda Guardian Army, who are still in a state of readiness, standing on the city wall to guard against the beasts outside the valley.

Because during the construction of the city wall, there were often fierce beasts in the forest coming, but fortunately, Yang Yunfei arranged the people who gave the alarm in advance. Otherwise, the consequences will be unimaginable, and there will definitely be casualties. This is also the reason why Yang Yunfei would rather give up hunting high-level dinosaurs and seize spiritual objects, and also step up the construction of the city wall first.

In fact, with the small poisonous dragon in the valley being cleared, the fierce beasts in the forest outside the valley have become the biggest threat to the Panda Valley, and this threat is constantly amplifying, and it has reached the point where it must be dealt with.

Yang Yunfei was really worried that if a group of fierce beasts came in at any time, they would even cause huge casualties to the pandas in the valley.

But even now that the city wall has been repaired, they still don't dare to relax too much, and they still have to continue to do a good job of preparedness.
