The ultimate secret realm can only be entered once, and only the most talented human geniuses are qualified to enter. If one's talent is not enough, one cannot enter the ultimate secret realm at all.
Emperor Xi gained huge benefits from the ultimate secret realm back then, but he did not have the chance to obtain the greatest benefit of the ultimate secret realm.
If Chen Lei had the opportunity to obtain the strongest inheritance of the ultimate secret realm, then he would most likely become the strongest person of the human race and protect the entire human race without any problem.
Naturally, Chen Lei was extremely excited and curious about this ultimate secret realm. His strength had now reached a bottleneck, and it would be difficult to improve rapidly in the short term. If this ultimate secret realm could allow him to greatly increase his strength in a short period of time, it would be a great help to Chen Lei.
"Chen Lei, if you can obtain the ultimate inheritance of the ultimate secret realm, I hope you can protect the human race for a period of time." Emperor Xi said to Chen Lei. This is also the obligation that Chen Lei should fulfill after obtaining the inheritance in the ultimate secret realm.
Chen Lei naturally agreed to Emperor Xi's request. Even if he did not obtain the ultimate inheritance, Chen Lei would never stand idly by when the human race was in trouble.
"Now, an emperor-level powerful man has appeared in the Tiandi Sect. I'm afraid that all races will mobilize their strongest resources. I'm afraid that a large number of peerless powerful people will emerge in the future." Emperor Xi said to Chen Lei again.
Chen Lei's understanding of the upper realm is far less than that of Emperor Xi. After all, it has not been long since Chen Lei ascended to the upper realm. But Emperor Xi is different. He has always lived in the upper realm.
Emperor Xi knew how deep the water in the upper realm was, and the background of each race was not as simple as it seemed on the surface.
Although the Tiandi Sect is powerful and has many masters with the title of emperor, it is by no means an easy task to completely unify the entire upper realm.
Of course, it is a fact that the overall strength of the Tiandi Sect is definitely the strongest among many ethnic forces.
Chen Lei nodded. He also knew that the top-ranked races in the upper realm, especially those ranked in the top 100, were definitely not so easy to exterminate.
During the development of the upper realm, there have been sects more powerful than the Tiandi Sect. However, none of the races ranked in the top 100 have been exterminated. The foundation of some races can really be called unfathomable.
This ultimate secret realm of the human race is the strongest foundation of the human race.
After explaining some things, Emperor Xi sent Chen Lei to the ultimate secret realm of the human race.
Now that time is running out, Emperor Xi naturally has to seize the time to allow Chen Lei to obtain the inheritance in the ultimate secret realm.
Soon, under the guidance of Emperor Xi, Chen Lei came to a mysterious space.
This mysterious space is located in the deepest part of the Xidi Palace, but it is a world of its own.
After Emperor Xi brought Chen Lei to this mysterious space, he made a series of hand seals with his hands. Countless runes flew out, embedded in the void, and were imprinted on this mysterious space.
Suddenly, a mysterious rune flashed, forming a huge portal that emitted a mysterious light.
Emperor Xi said to Chen Lei: "This is the ultimate secret realm of our human race. Every talented and powerful person who enters the ultimate secret realm will feel different. What kind of harvest you can get depends entirely on your luck and opportunity. What you can get in it depends entirely on your fortune."
