Immortality Begins with the Extraction of Skills

Li Xuan traveled to another world and became a jailer. Warriors are respected here, monsters and beasts are rampant, and there are even immortal land gods. In the capital prison, there are warrior prisoners and monsters that look human but not human. Inside the obscure and dark prison: [It is detected that the host is locking the target warrior] [Whether to extract the skills] "Yes!" [Extracting the top-grade skills from the heavenly realm—Yin Yang and Five Elements Chaos Technique] [The target warrior cultivates to perfection, and the host automatically cultivates to perfection] Boom! Li Xuan's realm suddenly broke through to the great master. He is only one step away from the land god.
