Please tell the emperor in heaven why he can only live for tens of thousands of years.

The setting of Gai Tiandi is that mortal cultivation can become immortal, and Gai Tiandi is the peak of the world cultivation circle. People without talent and beauty, people without atmospheric carriers, can't become emperors, and only one emperor can be produced within tens of thousands of years (the rules of heaven and earth can't bear too much, and it takes too much heaven and earth to become emperors). The emperor is the most common immortal, but the road to immortality has been cut off. Although the emperor has reached the level of immortals, one day, unless we find a way not to soar to immortality, we can become immortals in the world of mortals, but there are very few emperors who can become immortals in the world of mortals. The realm of the world of mortals is equivalent to the realm of surprises in ordinary Xianxia novels, saying what you say and creating rules. For example, Di Qing tried to kill Shi Ling, but Shi Ling was not born until 8,000 years ago. 8,000 years ago, Di Qing waved and made a killing gesture, revealing lost face. The murder was that he couldn't find Shi Ling at that time and turned himself into a violet. He waited for 8,000 years until Shi Ling appeared, and this will appeared again. With a wave of his hand, Shi Ling, second only to the imperial realm, was domineering and beheaded. Covering the Sky is a rare book in recent years, which is worth reading. Personally, I think it is the peak of Chen Dong, much deeper than the tomb of God.
