Result of hundreds of millions of years hard work
After Millions of years of research and knowledge-seeking, Zhong Xing was able to create the System. The neutral system is an AI that calculates And processes various techniques in an unfathomable speed than any celestials and immortals can dream to. Instead of electric energy like on earth, it relies on soul energy to sustain, circulate and calculate.

Anything can be devoured. so long as it doesn't have strong consciousness.
Neutral system Devours Energy from dead or alive and Converts the energy into Zhong Xing's personal Use. It can Convert the energy and create Pills, Weapons, Treasures, Living beings (Of course not a soul. Not yet) literary anything that the system has knowledge/formula of.

It Can Devour knowledge from World Core
Speaking of Knowledge It can devour knowledge of past and present of any worlds in existence. It stores the knowledge in its storage as data. Each world has a core that loves to share knowledge and gain in exchange. Only Neutral system can communicate with the world core as it doesn't have any physical or spiritual existence it's not sensed or discovered by anyone.

Ease in cultivation
