Becoming an immortal for the Twelve Heavenly Kings was indeed challenging.
Hong Yuye had mentioned it before. It requires all twelve kings to tread that path together.
Moreover, they couldn't be obstructed by the Heavenly King's Fortune. Achieving immortality was even more challenging for them than reaching the heavens.
However, this matter had nothing to do with Jiang Hao. He was only interested in the Abyssal Sea. If it wasn't related to the Dragon Clan, he wouldn't bother.
People from overseas could do whatever they wanted. It wouldn't affect him.
After much thought, Jiang Hao wanted to take out the ancient pages and let Gu Jin take a look at them. However, he gave up.
The ancient pages were related to the era. If it was used by Gu Jin, the consequences would be unimaginable.
Although the other party didn't seem like a bad person, appearances could be deceiving.
