Just that big opening, which was more than a mile long, took Yang Chen half a year to expand. Every sword was used by Yang Chen with all his might, even if it was a power that was infinitely close to the realm of the Heavenly Force, he would feel tired when facing the spatial interface.

At this time, no matter how high the cultivation is, it is not as useful as this kind of solid strength. Therefore, even though Yang Chen knew that Brother Li Cheng's cultivation was much stronger than his own, he didn't let Brother Li Cheng do it.

Half a year of boring chopping life, coupled with the crazy killing in the demon world, made Yang Chen's cultivation improve by leaps and bounds in just a few years, and directly entered the realm of the four grades of earth immortals." With the strength of his physical body, Yang Chen also entered the point of powering the sky very firmly.

When Yang Chen's family was slashing in the Demon Realm, the Third Yuan God also happened to have finished refining the last part of the Super Cave Mansion, and the three million miles of Super Cave Mansion had been completely integrated into the geographical map of mountains and rivers, and Gongsun Ling's cultivation surpassed the Eight Grades of the Earth Immortals when he was training, and was infinitely close to the Nine Grades of the Earth Immortals.

After Yang Chen expanded the entrance and exit of the connection, the Third Yuan God mobilized all his strength to refine it with all his strength, and with the help of the Merit Chapter, it only took two years to completely refine and control this large mouth that was more than a mile long.

The geographical map of mountains and rivers has been prepared, just waiting to verify whether Yang Chen's idea is correct. Under everyone's nervous gaze, a piece of space on the geographical map of mountains and rivers seemed to be suddenly divided, except for a piece of land that was only more than ten zhang wide, the rest of the land flew up directly, and slowly entered the big mouth under the control of the third elemental god, which was the black gas surging demon realm.

Boom, a loud bang. Wait until that space has completely entered the demon realm. Suddenly, the entire explosion turned into the tiniest particles, covering an area of almost the same size in the Demon Realm.

The land more than ten zhang wide was still connected to the entrance of the Demon Realm. The Third Yuan God had already controlled all the living beings in the geographical map of mountains and rivers, and was frantically following Yang Chen's previous method of refining space. Begin refining the exploding area at the entrance to the Demon Realm.

Yang Chen's merit flew out even more desperately, ten times faster than when he expanded the entrance and exit before. This is not the time to save money, just to be able to refine quickly.

Li Cheng stared closely in that direction, and at the same time, he was also trying his best to help the third elemental god. As long as this method is effective, it means that the Demon Realm can become Yang Chen's bag, and he no longer has to worry about the threat of the Zhao family.

Everything is difficult at the beginning, especially this kind of refining, which has to cross the spatial connection point. For at least ten days and ten nights ahead, there was no change at the entrance of the Demon Realm.

Although it was a space in the radius of Lixu, refining was not the previous way of swallowing whales. In the beginning, it was only a small inch of space. But if you can't refine even this inch of space for ten days and ten nights, I'm afraid that the efforts you will make in the future will only be useless.

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

The women saw Brother Li Cheng sighing, and their disappointment was beyond words. I want to comfort my father-in-law, but I don't know how to talk about it. Moreover, Yang Chen didn't seem to completely admit defeat, but kept staring over there. Undivided effort.

"Persuade him!" Brother Li Cheng was in a very bad mood, and he didn't want to talk much, so he just said something to Gao Yue, and then sat on the other side and pondered other ways.

Gao Yue slowly walked to Yang Chen's side. Just as she was about to speak, Yang Chen, who was engrossed in her hand, suddenly waved her hand and blocked the words she was about to say in her throat.

"I'll try again. Yang Chen's words were also not much. It's just a few words, but it expresses his determination not to give up.

Yang Chen's communication with the Third Yuan God was even more convenient than Gongsun Ling's. Quickly communicating the feelings of the refining process. The feedback given to Yang Chen by the Third Yuan God was that there seemed to be some invisible barrier at the entrance and exit of that space, and people could pass through. Things can pass, but the means of refining can't pass, which is very magical.

The space cannot be crossed, and if you want to refine it, it is an empty word, and the third primordial god has nothing to do. When he was worried, the second primordial god in the Immortal Slashing Knife jumped out directly.

"Use the Immortal Chopping Knife to Chop Sendai!" The meaning of the second primordial god is very clear, since the space cannot be crossed, then use the Chopping Sendai in the Immortal Chopping Knife that can cut through the space as a medium.

Yang Chen's mind moved, and the Immortal Slashing Knife quickly appeared in his hand, instantly transforming into a huge giant blade. With a bang, the huge immortal slashing knife was directly inserted between the geographical map of mountains and rivers and the demon realm, on one side was the land in the geographical map of mountains and rivers, and on the other side was the land in the demon realm.

The third primordial god didn't say a word, and directly sent the power of the geographical map of mountains and rivers along the Immortal Slashing Knife. Yang Chen also urged the merits chapter, and quickly sent a large amount of merits over, both prongedly.

Li Cheng and the other women watched cautiously not far away, especially Li Cheng, who stared closely at the land where the Demon Realm Immortal Slashing Knife was inserted, and couldn't take their eyes off it.

Just in the expectation of everyone, after countless black qi was entangled for a long time, the small stone next to the blade of the Immortal Slashing Knife slowly changed color, becoming the same color as the geographical map of mountains and rivers.

Immediately afterward, the land that was inserted around the Immortal Slashing Knife began to slowly change color. The thick black gas slowly dissipated, revealing the true face of the land.

With this small area, the ten-zhang wide piece of land that had been cut off at the entrance of the Demon Realm seemed to have an additional connection point in the Demon Realm, rapidly becoming thinner and longer, spreading rapidly, and connecting with the small piece of land that was less than the size of a palm.

Everyone was excited by this scene. Obviously, refining has achieved results, even if it is only a small point, but it is a breakthrough leapfrog achievement. The method proposed by Yang Chen was effective and could refine the Demon Realm.

Once you get past this most difficult breakthrough stage, the rest is much simpler. Based on that small palm-sized place, the Third Yuan God urged the power of the geographical map of mountains and rivers to expand the results of the battle little by little.

Every inch of territory expanded, the Demon Realm and the geographical map of mountains and rivers were connected by an inch, and the connection became more and more stable. When the connected place exceeds one zhang, there is basically no need to cut the immortal knife again. However, for the sake of safety, Yang Chen still let the Immortal Slashing Sword maintain the status quo until this space was completely refined.

The people in the joy did not notice the passage of time at all, and when they saw that the space had been completely refined, and the connection between the geographical map of mountains and rivers and the demon world had become a ** that was about to fill the entrance and exit of the entire space, they found that a whole year had passed.
