"Tut-tut...... Big brother, I find you too powerful. ”

Xiaohui admired Du Feng more and more, and he didn't blink his eyelids when he panicked. The story is so round that no one can see through it. Obviously, he killed Lao Wang's family, and also killed the bookstore keeper and two subordinates, but he didn't show any flaws.

To put it bluntly, those people were actually eaten by monsters, and Du Feng just played a role in fueling the flames. Besides, they are also looking for their own death, and come to the ruins to wreak havoc, otherwise they will not be eaten by monsters in the end.

"Don't be too happy, there's going to be trouble. ”

Du Feng is not optimistic about this matter, because he knows that troublesome things are still to come. Based on past experience, the owner behind the bookstore will definitely be the shopkeeper. It is not certain whether to hire a professional killer or to send someone from within the company.

"With the big brother here, we are not afraid of anything. ”

Xiaohui is now Du Feng, and he is full of confidence. I believe that no matter how difficult it is, he can overcome it. In fact, Du Feng himself knew that thanks to the rule that private fights were not allowed in Yundu City, and the monsters that appeared on time after the third watch, otherwise the bookstore manager would not be so easy to deal with.

The following days were relatively peaceful, and Du Feng took the time to exchange his formation experience with Captain Yan, which could be regarded as promoting his feelings. This was still useful, and there was a noticeable increase in the number of city guards patrolling the vicinity of the ruins. This way, the enemy has fewer opportunities to get his hands dirty.

About a month passed in the ordinary days, and during this month, he practiced on the third floor of the basement every day. Cultivation has been promoted from the early stage of the Feather Transformation Realm to the late stage, and it is not far from the eighth layer.

Perhaps because of the enemies that came at any time, as well as the sense of oppression brought by the monsters outside, Du Feng's cultivation had progressed quite quickly during this time. He didn't devour the war beast, and he didn't take any special pills, and he didn't dare to imagine that he could not have improved most of his cultivation in a month.

No wonder people have to come to Yundu City, the Yuan Power in the city is indeed more sufficient, and it can be said that it exceeds any other city on the Weiyang Continent. Du Feng also found a rule, that is, from the third watch at night to the fifth watch in the morning, during the period when monsters appeared, the efficiency of practicing and practicing was particularly high.

At first, because he was afraid of alarming the monster, he didn't dare to do much, but he just restrained his breath and held his breath and didn't dare to move. Later, I tried to move, but nothing happened. After all, it is on the third floor of the deep underground, and there are two floors of rooms separated by it, and there is also a formation protection.

After trying a few times, Du Feng found that it didn't matter if he exercised, so he tried to exercise gently. After observation, he found that luck would not attract the attention of the man-eating monster either. I just let go and concentrate on practicing in the room on the third basement floor. Not to mention, the cultivation effect during the period from the third to the fifth watch when there are monsters infested is particularly good.

In this way, more than ten days passed, and Du Feng's cultivation finally broke through to the realm of the eighth layer of the Feather Transformation Realm. It is equivalent to saying that without the help of any pills, it took him more than forty days to break through to a layer of cultivation. You must know that this is during the Feather Transformation Realm, and it is very difficult to break through each layer of cultivation. There are so many masters in Yundu City, it seems that it has a lot to do with the environment here.

Du Feng had a bold idea, he wanted to dig the basement a little deeper. Anyway, it was secretly constructed within the scope of the homestead, and the neighbor Lao Wang's house was already dead, so no one found out what he did.

"Big brother, so many rooms are enough, no need to dig anymore. ”

Xiaohui didn't understand what Du Feng was doing, and thought he was going to rebuild some more rooms. Although Du Feng's ability is very strong, digging soil to build a house is still a very tiring thing. With three floors of basement, there are enough rooms to dig it up.

"It's okay, big brother exercise his body. ”

Du Feng tried to dig further down, but found that the soil was getting tighter and tighter. When he dug the fourth layer, it was fine, but by the time he reached the fifth layer, the resistance was already very large, and when he dug the sixth layer, there was no soil at all, and it was all stones, and it was a whole stone.

This Weiyang Continent is indeed an artificially created floating island, especially Yundu City. If it were a natural continent, even if there were stones, it would not be such a large block, and it would be a large block all day long and there would be no seams at all.

In other words, on the territory of Yundu City, you can only dig down to a depth of five layers. If you dig again, you will encounter a rock layer, and if you force it open, you may alarm the city defenses, and even the upper echelons of the inner city will know about it. Du Feng couldn't take such a big risk, and he didn't dare to dig anymore when he reached the rock layer. Just trim it up on top of the rock layer and make it a decent room.

Because there were already four and five floors underground, Du Feng moved to the fifth basement floor, let Xiaohui live on the fourth floor, and Qin Siling moved to the previous room on the third basement floor. In this way, the rooms on the first and second floors can be filled in, leaving only narrow passages. Even if the surface is attacked and destroyed, the people below will not be affected.

Another reason why Du Feng did this was that he found that the deeper the underground, the more abundant the Yuan Power. I felt that the Yuan Force was emerging from the rock layer. When he himself meditated, he sat directly on the stone face. If it weren't for the fear of alarming the upper echelons of Yundu, he really wanted to smash the rock layer open to see what was hidden inside, and he also wanted to see how thick the rock layer was, whether it held up the entire Weiyang Continent.

In fact, Du Feng guessed that the entire Weiyang Continent was held up by a huge conical boulder. It is covered with soil, planted with trees, and artificially mimics the natural environment. Then it can be suitable for the survival of monsters, and the construction of cities for humans to live in.

But if he wants to dig deeper, it's wishful thinking. Because the rock layer gets harder and harder the further in, he can't dig with the weapon in his hand. Even if the emperor-level realm master came, he couldn't dig deeper. If it weren't for such a strong support, the Weiyang Continent would have been destroyed by the tenth-level demon beasts flying everywhere in the Triple Heavens, how could it still stand here and try its best to survive countless ups and downs.

Du Feng discovered this underground secret, I believe that there will be others in Yundu City who will find out, but there are definitely not many people who know about it. No one is willing to tell anyone about this method that can improve the efficiency of cultivation and improve faster than others.

He is not stingy, and plans to call Xiaohui and Qin Siling down. When you usually have time, you can sit on the stone face and practice more, I believe it will be beneficial to both their sisters and brothers.
