It's All the System's Fault

Chen Xuanka has been in the "Spiritual Vein Realm" for more than 200 years. Until one day, a silver-white girl who called herself "The System" suddenly jumped in front of him, claiming that she could help him in exchange for helping her escape from a certain "big terror" in the future. Chen Xuan: "... Why is this system so lively?" The girl who calls herself "Su" is hopping around in the system while promoting business: "Host, stop being so annoying! Your seal can only be crossed by me. This is the safest result!" When the binding scan started, Su screamed in horror: "Why are there corpses of other systems in your body?! And the same aura as the big horror?!" Chen Xuan calmly took out a jade sign and said, "Oh, those things you mentioned were all passers-by systems that came to 'help' me but ended up blowing up themselves." Su: "... Excuse me, is it still too late for me to run away?" But there is no way to escape by running. One is a "host assassin" whose cultivation is locked by a mysterious seal and specializes in various systems, and the other is an "escape system" who has escaped from the clutches of a big terror and is in urgent need of finding a powerful partner to hide in. The two of them combined - this wave must cooperate, but the method of cooperation is very hard-core. For others to build their foundation, she directly rubs the golden elixir, while for others to cultivate, she engages in "man-machine integration", not to mention the mortality rate is as high as 65%. After success, she will be permanently bound. From now on, you will be one of us, and you will never be able to separate your luggage and break up! Chen Xuan: "So the plan is... You become part of my golden elixir?" Su: "Yes!" Thus, a journey of cultivating immortality begins with a strange style: a sullen host who is always discreetly complaining, and a system that is too lively but reliable at critical moments. Face the unknown future and powerful enemies together.
