The Nest of 10,000 Dragons had lost the Kunlun Immortal, so they were living a very aggrieved life. They had to endure it. Facing the overbearingness of the Primordial God Mountain, they had no choice.
The Primordial God Mountain at that time was much stronger than it was now. The peak powerhouses were all present, enough to suppress the Myriad Races.
After suppressing the Number One Race in Eye of the North Sea, the Primordial God Mountain became the leader of the Myriad Races.
Then, they replaced the Number One Race and impeded the development of the other races. Whatever the Number One Race had done, the Primordial God Mountain copied. Not only that, but the Primordial God Mountain even intensified their actions.
The hero who slew the dragon became the evil dragon in the end!
When Big Sister Divine Silkworm mentioned this, her expression turned ugly.
