The demon king looked deep in his eyes and said, "There is a sinkhole hidden deep in the Dangmo Mountains. There are countless treasures in this sinkhole. I even speculate that this sinkhole is very likely a corner of the middle world that fell down, and there are a large number of spiritual treasures in it."
"What? How is this possible?"
After hearing this, the demon was horrified. He would never have thought that there was such a big secret deep in the Dangmo Mountains.
"Originally, I was planning to conquer Dangmo Mountain and then slowly search for the tiankeng, but now, this plan has completely failed."
"My Lord, since Dangmo Mountain is so important, why don't we send a large army to attack it? If we mobilize all our forces, we should be able to take Dangmo Mountain."
The demon said, just think about it, if they can really get the countless spiritual treasures in the tiankeng, how powerful they will be. They will definitely be able to sweep away other demon kings, unify the demon land, and become the next generation of demon emperor.
The demon king shook his head and said, "It's too late. According to my calculations, this tiankeng will appear in the world within a month. Even if we mobilize the army now, we can't take down Dangmo Mountain in a month. Once this tiankeng appears, it will definitely alarm the strong men from all sides. It's impossible for us to take the tiankeng for ourselves."
After hearing this, the demon showed a trace of disappointment. It was indeed difficult to mobilize an army that could conquer Dangmo Mountain within a month. It seemed that there was really no better solution.
The demon king then said, "Yu Gu, pass on my order immediately and have all the warriors above the Martial Emperor level stand by. Although we cannot monopolize the tiankeng, we knew the news earlier after all, so we must seize the initiative and advantage at the beginning."
After hearing this, the demon named Yu Gu said, "Master, don't worry, I will definitely handle this matter beautifully."
"Go ahead..."
The demon king waved his hand and ordered Yu Gu to retreat.
After Yu Gu retreated, he immediately began to issue a demon gathering order, asking all the demon descendants above the ninth level of Martial Emperor to gather.
…
A few days later, Chen Lei let out a long sigh, and looked at the Dangmo Mountains below, which stretched across the vast devilish land like a magic dragon, and was slightly dazed.
It would have been better if he hadn't investigated. After careful investigation, he found that the depth of the Dangmo Mountains was far beyond his imagination.
The area where they were located could only be considered the outskirts of the Dangmo Mountains. It was simply impossible for him to set up formations and restrictions throughout the Dangmo Mountains.
He could only set up a formation in the area near Dangmo Mountain. If he really wanted to set up a formation that covered the entire Dangmo Mountain Range, it would be impossible to complete it without thousands of years.
Chen Lei naturally had no time to waste here. He just redesigned some formation restrictions based on the original formation of Dangmo Mountain, making the formation restrictions of Dangmo Mountain twice as powerful as before.
Although this effect did not reach Chen Lei's ideal state, Yu Zhenshan was extremely satisfied. With such a ban, at least this line of defense of Dangmo Mountain would be absolutely impregnable for hundreds of years and there would be no problems.
