The worst demon beasts that appear here are also advanced Xuan Immortals, and the realm of the Earth Dragon is a few lines behind. Even if Yang Chen counts all the magic weapons in his body, the Great Yin and Yang Five Elements Sword plus the Great Yin and Yang Five Elements Technique, and then counts the Yellow Turban Lux Alchemy Technique, and pulls up the Roaring Sky, he is not necessarily the opponent of a demon beast here.

What's more, within a thousand miles around here, there are at least five or six demon beasts at the peak of Xuan Immortal, and if they do it here, isn't that looking for death?

"It's not your turn to kill the monster. Li Chengbai glanced at Yang Chen, and said angrily: "Do you have that strength?"

"Then what am I going to do?" Yang Chen asked puzzled. If you don't kill the demon beast, what else can you do here? Alchemy?

"Refine that space exit!" Li Cheng didn't want to look at Yang Chen's appearance anymore, so he said directly lazily.

The hole with a radius of 100 miles dozens of miles on the opposite side, Yang Chen had already judged it just now, it was the same as the core of the Demon Continent was a spatial entrance, to be precise, it should be a space exit, one-way, and you can't enter it here. In essence, they all belonged to the objects that Yang Chen had obtained that could be refined.

"So big?" Yang Chen looked at the huge exit that was hundreds of miles long, and was dumbfounded: "How can this take thousands of years, right?"

In the mortal world, even if Yang Chen had refined the core of the Demon Continent, even if he had refined the entrance of the Slashing Immortal Terrace, the sum of those two was not half the size of this, not even a tenth. The largest door hole in the Cutting Immortal Terrace is only a few tens of zhang high, and the core of the Demon Continent is simply a point, compared to this, it is like a cloud of mud.

It took Yang Chen hundreds of years to refine the core of the Demon Continent. The entrance to the Refining and Slashing Immortal Terrace took hundreds of years with the help of hundreds of immortal-level machine spirits, so how long did it take for this demon beast space to exit?

"What's the matter, your cultivation is still high!" Li Cheng completely ignored Yang Chen's next hardship. It may be that Yang Chen's rogue words before caused Li Cheng's dissatisfaction, so in turn it was vented on him at this time.

"But this is too big...... "It was precisely because Yang Chen had experience in refining space that he knew the hard work of refining, and in the face of such a big behemoth, Yang Chen couldn't help but feel a little discouraged. It's hard to say whether it can be refined before ascending.

"Stop talking nonsense, hurry up and get to work!" Li Cheng urged with an impatient face: "When you want benefits." You have to think about what to do. ”

Yang Chen complained in his mouth, but he didn't stop in his hand, his divine sense had already reached over directly, and he began to contact the spatial exit to carry out the first step of refining work.

The first refinement was not really refining, but to establish a connection between Yang Chen and the exit of this space, so that Yang Chen could refine the space anytime and anywhere.

The refining of this step is very important, and the exit of the demon beast space is so large, the time required is also a very considerable number, and there is no way to stop it as soon as you start to move. If it weren't for Li Cheng by his side. Yang Chen didn't even dare to move easily here.

As soon as the divine consciousness is actively probed, even the thinnest divine consciousness thread cannot escape the fate of being discovered. The power of the demon beasts here is by no means comparable to some super sects in the spirit world. In just a moment, Yang Chen was targeted by dozens of demon beasts at the peak of Xuan Immortals.

Li Cheng urged Yang Chen in his mouth, but the person had already appeared directly. Blocking Yang Chen behind him, he pounced directly towards the nearest demon beast.

And then the next thing, basically there is nothing to do with Yang Chen, he just needs to concentrate on the exit of the refining space, and all the demon beasts are resisted by Li Cheng. However, before he was completely immersed in refining, Yang Chen still released the earth dragon and asked him to assist Li Cheng in blocking those demon beasts. After all, the earth dragon is also at the level of the sixth grade of Xuan Immortal, even if it can't help a lot, it can help a little.

The earth-shattering roar of the demon beast sounded in my ears. But Yang Chen didn't care anymore. He believed in Li Cheng's judgment and even more in Li Cheng's ability. Since Brother Li Cheng was here and asked him to start refining immediately, then Yang Chen believed that he would definitely have no problems.

Faintly, the surrounding mountain peaks and the ground seemed to have collapsed, as if it had become a testing ground for creation. The terrain began to change constantly, a mountain peak, a valley bottom, every change, accompanied by a movement like the sky falling, earth-shattering.

What is shocking is that within the area where Yang Chen is located, there has been no change, and he has maintained his original state without moving. No matter how powerful the demon beast attacked, it was not affected in the slightest. On the periphery of Yang Chen's body, there seemed to be an invisible transparent cover, protecting Yang Chen in it.

During the refining process, Yang Chen was also thinking about how this demon beast space exit was formed. Was it opened by the Zhao family with great divine powers just like the mortal demon continent, or did the Zhao family first discover this opening and then make this place of trial according to local conditions? What does this demon beast space exit have to do with the nine Xuan Immortal-level demon beasts on the periphery?

Without the evidence of the ancestors of the Zhao family, no one would be able to know the reason, Yang Chen just guessed like this, and did not want to know the root right away. However, Yang Chen was very curious, as soon as Brother Li Cheng saw the exit of this demon beast space, he asked Yang Chen to refine it, why is this?

Now Yang Chen can basically determine that the exit of that demon beast space should be the source of the thousand-year-old demon tribulation in the spirit realm, and it is also the source of those demon beasts. The refining space, it is best to be able to completely block this exit, then the thousand-year demon tribulation will appear, which is of course the best.

However, Yang Chen knew very well that if he wanted to completely refine this space exit, and completely plug this button, let alone a thousand years, maybe double the time would not be enough. This was still based on the premise that Yang Chen didn't do most of the things and only focused on improving his cultivation and refining space. If I get distracted again, I don't know how long it will last.

Yang Chen didn't even know if those Demon Beasts at the peak of the Xuan Immortal Peak crawled out during the thorough refining process, it would affect his refining process. In short, this is a very tricky thing to do, and we can't afford to do it yet.

How was the thousand-year-old demon tribulation accomplished in his previous life? Yang Chen couldn't remember the reason until now, it seemed to happen so inexplicably, and then it ended inexplicably. It is very strange that there is nothing left except for the heavy casualties caused to the monks in the spirit realm.

Yang Chen, who was immersed in the refining process, could hardly feel the passage of time, when he felt that he had completely completed the first stage of refining, when he opened his eyes, looking at the surrounding situation, even if he was as calm as Yang Chen, he couldn't help but widen his eyes.
