In a few hours, time flew by, and Chen Nan was exhausted and sweating profusely.
It was his first attempt at refining the skeleton of an invincible strong person, and it was extremely difficult. With his current strength, he could barely refine it.
But the price paid was enormous. Meanwhile, the vitality he had refined in the Ancient God Demon Battlefield had been consumed by half after a few hours.
Chen Nan's expression turned cautious. With a move of his hand, he took out an elixir from his Storage Ring and consumed it.
Although the Chaos Sacred Body's conversion of death energy into vitality was sufficient to sustain him, Chen Nan needed to maintain his strength at peak state all the time so that the avatar he refined could exert its maximum power.
In some aspects, the body structure of the Heavenly People Clan surprisingly had advantages over the Human Clan.
