As the world is swallowed by the Abyss, Li Changsheng transmigrates into the heart of a sacred tree on the verge of dying. Beyond the barrier, abyss-corrupted blood beasts are frantically gnawing at the last line of defense, while the only blind elf apprentice waits for death in despair. At this desperate moment, he awakens a cross-world summoning System, disguising another world as the full-dive online game "Era of the Divine Tree" and summoning Blue Star players to descend. Watch as these fun-loving players, known as the Fourth Calamity, use their outrageous ideas to drive the Abyss's monsters insane!
