Song Yi, a good-for-nothing casual cultivator, struggled to survive amidst the rejection and contempt of his family. Unexpectedly, the gears of fate suddenly turned, and the killing upgrade system awakened, opening an unprecedented counterattack for him. Every time an evil cultivator is slain, peerless skills are collected into his pocket; every time a ferocious beast is slain, a thousand years of spiritual marrow is his. However, this heaven-defying opportunity also comes with a heavy price. After each breakthrough, the cultivation level will be sealed for three days.
In this dangerous world of cultivating immortals, enemies are chasing after them and aristocratic families are besieging them one after another. Elder Jin Dan's contempt and the Song brothers and sisters' Immortal Killing Sword Formation all tried to crush him. But Song Yi relied on the help of the system to fight bloody battles in desperate situations again and again. The loving companionship of the demon fox Biyao adds a touch of warmth to his cold journey of cultivating immortality.
The Heavenly Thunder Tribulation Fire is a test for him to temper his Taoist heart; the Nine Nether Demonic Waves are an opportunity for him to ascend to the supreme level. Let's see how Song Yi uses the system to refine the Three Thousand Avenues, breaks the shackles of blood, and in this world of immortal cultivation where the weak eat the strong, he can carve out his own path to eternal supremacy with one sword!
