Self-destruction is the act of detonating all the energy within one's body at once, often with a destructive power several times or even tens of times greater than their regular attack power.
Although the Elemental Giant's strength had regressed quite a bit due to the loss of his territory, it still posed a threatening fatality to Zhou Tian when it resorted to self-destruction. Zhou Tian faced immense danger too. Although he successfully weakened the explosion's power by almost half using the power of his Time Domain, he ended up severely injured due to the Giant's self-destruction.
However, given Zhou Tian's multiple abilities at that time, as long as he wasn't instantly killed, his death was rather unlikely. By using his skills to recover some of his HP, and the time domain to accelerate his healing, Zhou Tian was able to recover from his injuries in a short time.
