It took Yang Chen half a year to expand just how many mouths there were. Every knife is made by Yang Chen with all his strength. Even the power that is infinitely close to the realm of powerholding, when facing the space interface, he will feel tired.

At this time, no matter how high the cultivation is, it's not as useful as the strength of firmness. So, even if Yang Chen knew that brother Li Cheng's accomplishments were much better than his own, he didn't let brother Li Cheng do it.

Half a year's boring hacking life, coupled with the crazy killing in the demon world, made Yang Chen's cultivation progress rapidly in this short few years, and directly entered the realm of the four immortals. Physical strength, Yang Chen is also very determined to enter the point of powering the sky.

When Yang Chen and his family were killing in the demon world, the third God just finished refining the last part of the super cave. The three million mile super cave has been fully integrated into the geographical map of mountains and rivers. Gongsunling's accomplishments surpassed the Eight Immortals in the experience, and were infinitely close to the nine immortals.

After Yang Chen expanded the entrance and exit of the connection, the third God mobilized all his strength to refine. With the help of the merit chapter, it took only two years to completely control the refining of this one mile long mouth.

The mountain and river map has been prepared, only waiting to verify whether Yang Chen's idea is correct. Under everyone's intense gaze, Xu Fangyuan's space in the geographical map of mountains and rivers seems to be abruptly split. Except for a piece of land that is only ten feet wide, the rest of it flies directly and slowly enters the big gap under the control of the third God, which is the devil kingdom of black gas.

Boom, a big bang. When that space completely entered the demon world, suddenly the whole explosion became the smallest particle, covering an area about the same size in the demon world.

The ten foot wide land is also connected to the entrance of the demon world. The third God has controlled all the creatures in the geographical map of mountains and rivers. According to Yang Chen's formula of refining space, he began to refine the explosive area at the entrance of the demon world.

Yang Chen's merits and virtues are more deadly, ten times faster than before when he expanded the entrance and exit. At this time, it is not the time to save money, just to be able to refine quickly.

Li Cheng stares at that direction tightly, at the same time, he is also trying his best to help the third God. As long as this method is effective, it means that the devil kingdom can be Yang Chen's bag, and there is no need to worry about the threat of Zhao family.

It's hard at the beginning of everything, especially the refining that has to cross the spatial connection point. At least ten days and nights ahead, there is no change at the entrance of the demon world.

Although it's the space of Li and Xu Fangyuan, refining is not the way of whale swallowing before. At first, it's only the smallest inch of space. But if you can't refine even this inch of space for ten days and ten nights, I'm afraid the later efforts are just useless.

Li Cheng looked at the result in front of him, and seemed to sigh with disappointment. It's not that they don't work hard, but I'm afraid that such a method will not work and can't achieve the intended goal.

Seeing brother Li Cheng sighing, all the girls expressed their disappointment. I want to comfort my husband, but I don't know how to talk about it. Moreover, Yang Chen didn't seem to admit the failure completely, but kept staring at the other side and concentrated on her efforts.

"Persuade him!" Elder brother Li Cheng was in a bad mood and didn't want to talk more. He just said to Gao Yue and sat on the other side to think about other ways.

Gao Yue slowly walked to Yang Chen's side, and was about to open her mouth. Yang Chen, who was absorbed in her hand, suddenly waved her hand and blocked her words in her throat.

"I'll try again." Yang Chen's words are also not many, just a few words, but expressed his determination not to give up.

The communication between Yang Chen and the third God is more convenient than that between Gong and sun Ling. They communicate with each other in the refining process. The third yuan God's feedback to Yang Chen is that there seems to be some invisible barrier at the entrance and exit of the space. People can pass, things can pass, but the means of refining cannot pass. It's very magical.

Space can't be crossed. If you want to refine it, it's empty talk, and the third God has nothing to do. At the time of worry, the second God in the chopping immortal blade jumped out directly.

"Use the immortal chopping knife to cut Xiantai!" The meaning of the second God is very clear. Since the space cannot be crossed, then we can use the cutting platform in the cutting immortal blade which can cut the space as the medium.

Yang Chen's mind moved, and the immortal cutting knife appeared in his hand quickly, turning into a huge blade in an instant. With a crack, the huge immortal cutting knife is directly inserted between the mountain and river map and the devil kingdom. On one side is the land in the mountain and river map, and on the other side is the land in the devil kingdom.

The third God, without saying anything, directly sent the power of mountain and river geographical map along the immortal chopping knife. Yang Chen is also a piece of urging merits and virtues. He quickly sent a large number of merits and virtues to the past.

Li Cheng and the girls are watching carefully not far away, especially Li Cheng. They are staring at the land where the devil Kingdom's immortal cutting knife is inserted.

In the expectation of the public, after countless black Qi entwined for half a day, the small stone next to the edge of the immortal chopping knife slowly changed color, which was consistent with the color of the geographical map of mountains and rivers.

Then, the land around which the immortal cutting knife was inserted began to change color. The thick black air dissipated slowly, showing the true appearance of the land.

With this small area, the ten foot wide land that was originally cut off at the entrance of the demon world seems to have an additional connection point in the demon world. It grows and thins rapidly, spreads rapidly, and connects with a small area less than the size of a palm.

Everyone was excited by the excitement of the scene. Obviously, the refining and chemical industry has achieved results, even if it is only a tiny bit, but it is a breakthrough and leaping achievement. Yang Chen's method is effective and can refine the demon world.

Once we have crossed the most difficult breakthrough stage, the next thing is much easier. Based on that small area, the third God urged the strength of the geographical map of mountains and rivers, and gradually expanded the results of the war.

For every inch of expansion of the territory, there will be more than one inch of connection between magic world and mountain and river geographic map, and the connection will become more and more stable. When the connecting place is more than one Zhang, there is basically no need to cut the immortal blade again. However, in order to be safe, Yang Chen still keeps the status quo of the chopping immortal blade until Xu Fangyuan's space is thoroughly refined.

The people in the joy did not find the passage of time at all. When they saw that the space had been completely refined, and the connection between the geographical map of mountains and rivers and the devil kingdom had become a large area that was about to fill the entrance and exit of the whole space, they found that the time had passed for a whole year.
