This Dark Ultraman Is Too Righteous

(A fanfic derived from Ultraman Nexus, not systematic, not time-travelling, not cool, not invincible, hell difficulty.) On a stormy and rainy night, a car was speeding on the highway. In the car, the fate of a family of three is shrouded in darkness. The father revved the engine to the maximum, and the mother sat in the back seat, softly comforting her crying son. "Don't cry, Xingquan, we can escape soon!" Behind him, creepy wailing sounds kept coming. Countless weird tentacles were chasing them closely. If you hesitate even a little, you will end up like the poor people behind you who were devoured. "Bang!" A huge alien beast fell from the sky and hit the front of the car. His father had no time to brake and hit the alien beast and died on the spot. His mother held Ouyang Xingquan tightly in her arms, and Ouyang Xingquan opened his eyes wide in horror. When the alien beast was about to bite Ouyang Xingquan, a figure suddenly appeared. Punch the alien beast into the ground... I was rescued... And the one who saved me... Not light, but darkness... This is a story about a young man who replaces light with darkness, a story about struggling in despair and being reborn in the darkness - that is the story of me, Ouyang Xingquan.
