The Kun Peng Pavilion was something Lin Feng bestowed to Shi Tianhao when he had just formed his nascent soul. While it was a Gestation level magic treasure, its foundations were strong. After all, it was formed from the blood and flesh of an Undying Demon Soul Third Level Immemorial Kun Peng.
With this foundation, he further inserted a special stone and the remains of the Heavenly Wind Treasure Fan.
This not only made the Kun Peng Pavilion into a treasure with immense potential, but also made it devastatingly powerful. It was much more powerful than other magic treasures of the same level and was one of the few the Gestation level magic treasure that could challenge magic treasures of higher levels.
After Shi Tianhao himself had entered the Immortal Soul stage, his powers increased massively. As the Kun Peng Pavilion did not reach the Metaplasia stage, the increase of its powers could not compare to the increase in its master’s powers.
