I Use Cultivation to Prevent Global Catastrophe

In 2035, a super earthquake tore apart the Sea of ​​Japan, a 100-meter tsunami swallowed up 90% of the land, and human civilization was crumbling in the vast ocean. When retired soldier Luo Chen was dying, he drifted to Point Nemo, the most desolate place on earth, and accidentally broke into the secret deep-sea realm left by the pre-Qin cultivator Jiang Ziya. After a thousand years of remnant souls were empowered and passed on skills, and Qingfeng sword pointed at him, he became the only "Chosen One" who mastered the method of cultivation in the apocalypse. When the resurgence of spiritual energy swept the world, strange beasts were running rampant, and superpowers were separatist, Luo Chen held the "Tai Gong Yin Talisman Sutra" in his hand, used beast pills as food and blood as ink, and opened a path to immortality in the wasteland. He not only needs to hunt down the ninth-order deep-sea behemoths to stabilize his cultivation, but also compete with superpowers from all over the world for survival resources; he not only needs to protect the "Kunlun Fortress" established by the Dragon Kingdom on the roof of the world, but also faces the threat of death when the initiation technique dissipates at any time. He kills decisively, but also retains his chivalrous tenderness; he pursues immortality without forgetting the safety of the people. Let's see how the good-for-nothing sailor returns from the deep sea, uses his three-foot green blade to clear away the haze of doomsday, and lets the fire of Eastern cultivation reignite in the world!
