Douluo Continent: The Angel of the Dead, Shrek's Revenge

When Qin Chuan's soul crosses over into the world of Douluo Continent II: The Peerless Tang Sect, he awakens as the youngest son of Bibi Dong—a woman who perished ten thousand years before his rebirth. Accompanying his new life is the awakening of the Revenge System, a force whose purpose is spelled out plainly in its name. By slaying the students of Shrek Academy and everyone connected to them, Qin Chuan earns Vengeance Points—currency that can be exchanged for items and even used to travel between parallel universes. His fate soon becomes entangled with that of Ye Guyi, a descendant of Qian Renxue who follows the guidance left behind by her ancestors to the site of Qin Chuan's burial. The moment she opens the cave, a powerful suction force engulfs them both, dragging them down into a parallel universe together. What follows spans decades of unrelenting pursuit. Qin Chuan ultimately cuts down every last member of Shrek Academy, steps across a heavenly staircase formed from countless dead souls, ascends to the realm of the gods, and personally beheads the God King Tang Shenwang—at last claiming the vengeance that drives him.
