Immortality Starts from the Gate of Two Realms

The Yunluo world is full of spiritual energy and has many natural and earthly treasures. However, there are many sects, and the broomstick is precious. The monsters are ferocious and fight each other endlessly, making the casual cultivators miserable. The world of demons is wide open, everyone has skills to practice, the various arts are prosperous, the system is stable, and there is no danger of death. However, the spiritual energy is declining, and the casual cultivators are miserable. It just so happens that the casual cultivator Yunshu has a two-realm door that can freely travel between the two worlds.
