I Transmigrated to the Cultivation World and Made My Own System to Reach the Top

Hai Ziqiang, an ordinary office worker from the 21st century, accidentally transmigrated to the world of immortal cultivation. He had no System and no cheat powers.

Relying on the knowledge he brought from his previous life, he started by creating a spirit-energy computer. He gradually upgraded it, eventually integrating a host of functions: sensing the outside world, breaking restrictions, deducing cultivation techniques, storing items in a personal space, accelerating the growth of spirit plants, bringing the dead back to life, traversing the void, creating things from nothing, growing stronger by killing enemies, and location sign-ins.

He steadily increased his cultivation, changed the balance of power in the immortal realm, and eventually reached the peak, roaming freely between heaven and earth.

Along the way, he also uncovered the secret behind his transmigration. In the end, he tore through the void and returned to Earth.

Before leaving, he created a large number of Systems with all kinds of functions and scattered them throughout the cultivation world, where they would seek out transmigrators and bind themselves to them.
