Under that immense torture and immense pain, he wasn't able to do a thing at all.
He was at his wit's end.
The suffering was immense and Yichen felt like there was no hope.
The God-binding chains forced him into an even more tragic state.
It was incredibly excruciating and bound everything in his body, forcing even the great talent, Holy Light and the Ancient Phoenix Mediator inside of him to be in a state of deep sleep.
If it wasn't for his mere Partial Immortal realm, it shouldn't have any effects on the ultimate talent Holy Light but, the current him was still weak as he only stepped into the paths of the Immortal, therefore, it was easily able to affect it.
Not to forget, the Death Eclipse Mirror was also distracting and tormenting his mind, making him unable to activate either the Holy Light's power or the Ancient Phoenix Mediator on time.
With all his source of power being obstructed, Yichen was left in immense suffering as if his doom had finally arrived.
