Zhao Xiaofan is an ordinary handyman disciple of the Tianyan Sect who accidentally crosses over to Blue Star, which lacks spiritual energy, and encounters illegal personnel entangling him as soon as he lands. Fortunately, his portable sect token can communicate across two realms, using it to build a communication channel between the immortal cultivation sect and Blue Star. The sect concentrates on studying Blue Star's knowledge of mathematics, physics, and chemistry to develop spiritual energy equipment, while Blue Star collects rare materials from other realms to forge special alloys. Both sides share advantageous resources, and a two-way empowered two-realm development layout officially begins.
