Chen Lei also knew that although the Qingyang Mountains were the fiefdom of the Qingyang Sect, it was simply unrealistic for the Qingyang Sect to fight alone in the Qingyang Mountains. The biggest problem restricting the Qingyang Sect was that they had few people and few experts.
However, the Qingyang Mountains stretch for millions of miles, and the number of people coming from the Qingyang Sect this time is only a little over 100,000.
These more than 100,000 people entering the Qingyang Mountains were no different from a few drops of water entering the sea; not even a single ripple could be created.
However, Chen Lei also knew that the natural treasures of the world could not be monopolized by one sect. As long as the Qingyang Sect could continue to grow in strength within the next hundred years, that would be enough. It was not realistic for the Qingyang Sect to control the entire Qingyang Mountains with its current strength.
However, in order to allow the disciples of Qingyang Sect to have a foothold, Chen Lei still tried his best and went deep into the Qingyang Mountains for more than 100,000 miles. He set up a ninth-order heaven and earth-level formation along the way, and designated the more than 100,000 miles of Qingyang Mountains as the restricted area of Qingyang Sect.
As long as they do not leave the protection range of this ninth-order heaven and earth level formation, the disciples of Qingyang Sect should not encounter too much danger. But once they step out of the protection range of this heaven and earth level formation, they can only rely on their own strength.
This ninth-order heaven and earth level formation also came from the Thunder Emperor Palace. Otherwise, with Chen Lei's current strength, it would be impossible for him to set up a formation of this level.
After doing all this, Chen Lei said goodbye to Chen Tangxuan, his parents and others, boarded the Xuanmeng troop transport warship, and returned to the Xuanmeng Academy.
This time, Chen Lei and Nie Qianran, Bi Manman, Lei Yu, Jingjing, Kong Xuan, Xiong Da, Shi Er and others prepared for the battle and prepared to go to the sky battlefield.
Three months later, news came from Xuanmeng Academy, asking Chen Lei and others to gather at the academy and prepare to go to the sky battlefield.
After Chen Lei and others arrived at the square of Xuanmeng Academy, they saw tens of thousands of students gathered in the square.
These students can almost be said to include all the students of Xuanmeng Academy, including new students, old students, and even students from thirty or forty years ago.
Some of these students have graduated and are now independent, while others are still practicing in Xuanmeng Academy.
However, this time, because of the sky battlefield, almost everyone gathered together to enter the sky battlefield.
It is because there are too many opportunities on this sky battlefield.
Now, some senior officials of Xuanmeng Academy have already discovered that within this sky battlefield, there are many treasures left behind by powerful people, and most importantly, there are perfect soul seeds.
The importance of soul seeds is unquestionable, and some soul seeds above the ninth level have another characteristic, which is eternal immortality.
Even if it is merged by a strong man, once this strong man dies, the soul seed will be reborn and reincarnate again, turning into a new perfect soul seed.
This alone is enough to attract countless powerful people.
This is because the reincarnated soul seeds often carry the martial soul imprint of the fallen warrior. Such a martial soul imprint can make even martial ancestor-level warriors jealous, and can quickly increase the speed of martial soul cultivation.
