Healing in the Mountain Cave

White mist roiled within the formation like a powder keg set ablaze, its overwhelming energy raging like wind and waves.

The surging energy poured forth, charging straight at Wei Wushuang, who had launched the attack.

Caught completely unprepared, he was sent flying hard.

Even as he flew through the air, a smug smile remained on Wei Wushuang's lips.

With such a huge commotion outside the formation, how could the interior possibly remain peaceful?

Inside the Five Elements Eight Trigrams Formation.

Upon entering the formation again, Su Shi'er immediately felt immense pressure.

Only after his cultivation had improved and he faced this formation once more did he suddenly realize that its power far exceeded his judgment from back then.

"No wonder... no wonder it was able to seal Hou Sihai in this place for four hundred years."

"The power of this Five Elements Eight Trigrams Formation actually changed according to the cultivation realm of whoever entered it?"

"It seemed... the one who laid this formation truly had a benevolent heart. Though he trapped Hou Sihai with it, he had no wish to harm too many innocents. As long as those who entered did not attempt to break the formation, there would not be much danger."

Standing amid the formation, Su Shi'er dragged his battered body as he looked around, immediately reaching a further conclusion.

His entering the formation this time had mainly been to avoid disaster, an act forced upon him by circumstance.

On the other hand, it was also because of his agreement with Hou Sihai.

The agreed date was approaching. How much help he could offer while badly injured was another matter entirely.

But if he did not come, that would mean breaking the agreement. He had no desire to bear the consequences of violating a heart demon oath.
