Ye Chen, a young man with a mixed spirit root, used an ancient jade to activate the counterattack system. He slapped proud prodigies, shattered golden cores, and stepped on the immortal alliance, cultivating the Chaos Guiyuan Technique in three years. But on the night the ancient jade shattered, he discovered that the system was actually the Demon Lord's possession trap! His father used his physical body to nail demons for eight thousand years, his mother's remnant soul guarded the forbidden area, and the nine demon-suppressing nails could not last for three springs and autumns. Ye Chen alone killed his way into the nine-layer forbidden area, his meridians turning into pythons, his bones forming arrays, and his heart becoming a palace; every layer he descended doubled the time. The immortal alliance surrounded the mountain, the demon-slaying alliance appeared, and all enemies were waiting for him to die before the Demon Lord broke the seal. But he had only one sentence: "The path my parents paved for me with their lives, even if I have to crawl, I will finish crawling."
