Fourth Layer of Wild Instinct, Xingtian Giant, has no vital weaknesses.
"Come on!"
To deal with the Space-based Annihilation Cannon that might breach the World's Veil, Green judged that the Fourth Layer of Wild Instinct Xingtian Giant transformation is the most perfect response. Although higher layer transformations could provide stronger power, they would also force Green to bear more pressure.
This pressure comes not only from the Space-based Annihilation Cannon, but also from the Sky Mountain Marine World itself.
Compared to the pressure that Green might need to endure, the real bearer is the world itself; Green's pressure is insignificant compared to what this world endures.
Boom!
