There was no better opportunity than this.
In the battle with Shi Zhong, he was nearly pushed to the brink of death, facing the threat of mortality. But with Shi Hao's character, the more desperate the situation, the more resilient he becomes. Thus, he ultimately claimed victory.
He began to experience death and processed the insights from this battle.
Suddenly, half a year passed just like that.
Shi Hao abruptly awoke from his near-death state, and immediately began to make a sacrifice.
With enough understanding, he could now attempt the Eight Sacrifices.
After the sacrifice, the Power of Heaven and Earth flowed in abundantly, actively repairing Shi Hao's damaged physical body and soul.
This was why Shi Hao hadn't bothered to heal himself. Since he would be cleansed by the Power of Heaven and Earth, why go through unnecessary trouble?
After ten days, he finished the tempering with the Power of Heaven and Earth.
Eight Sacrifices!
