(Power fantasy + decisive and ruthless protagonist + multiple heroines + a touch of ensemble cast + takes off after Chapter 50) The river of time surged with crashing waves. Lin Yifei struggled with all his might to race upstream. The sight of the ravaged world brought tears to his eyes; Seeing his companions die before him filled him with anguish; The atrocities committed by invaders from another world made him seethe with rage; But as only an S-rank ability user, he was powerless to change anything. He could only make one last desperate attempt. Before his consciousness nearly faded, he leapt with a splash into the farthest upstream point of the river of time he could reach, sending sprays of water flying... "In the next timeline, I'll become an SSS-rank powerhouse as fast as I can, so I can change everything!" he gritted out to himself before his consciousness vanished.
