The eruption of the Heart Tribulation Fire is at the cost of life.
If he maintains this state without ending, the Heart Tribulation Fire will continue to burn, eventually draining everything within his body, ultimately turning into an empty shell.
In a certain sense, the Heart Tribulation Fire is a Forbidden Technique, a type of incredible energy that bursts forth by burning oneself.
It can let him transform into dazzling fireworks and burn himself out.
Yet, this power is controllable.
The human body undergoes death and rebirth every day.
Every moment, cells march toward death.
Short-term ignition of the Heart Tribulation Fire does not cause substantial harm to the body.
The depletion of Essence Qi and spiritual power, and the body's overexertion, can be restored with simple rest.
As for the moment requiring the burning of one's life, without any means to go all out, it rather becomes a form of despair.
