The mightiest Heavenly Demon had reached the Golden Immortal level, not weak by any means.
But clearly, Yu Tianfeng was stronger. Even the Golden Immortal level Heavenly Demons couldn't last many rounds against him and were eventually suppressed and sealed by him.
Five years later, Yu Tianfeng and the others left.
Only then did Lu Yi have the opportunity to absorb the Chaos Divine Crystal.
Over these years, his main focus had been the Array Tao.
At this moment, the Great Array he was inscribing was even stronger than before. He directly created an extremely powerful concealing Great Array to cover his Cultivation Room and began his closed-door cultivation.
The Chaos Divine Crystal was a white crystal, with white flowing light flickering within it. However, upon closer inspection, this white light seemed to contain endless splendor.
