"How is this possible? What method has he used?" the Radiant Immortal King roared in his heart. As an advanced immortal king, he was one of the higher-ups in heaven before he changed his status, which was why he knew many secret techniques.
But many secret techniques would lose their effectiveness once they reached their level.
With his power, he could have formed his own divine kingdom. His comprehension of the laws of heaven and earth was at a level that ordinary people did not dare to imagine.
It could be said that 99% of the various secret techniques that could increase one's strength had already lost their effectiveness at his level.
He also had secret techniques that could surpass several major realms at a low level. However, it was meaningless at his level.
A secret technique that could allow one to rise to a lower realm was already incredible. Moreover, one would often have to pay an extremely painful price, including one's lifespan.
