Super Immortal Cultivation System

Lin Tian, an otaku, brought a game system called "School Development" and was reborn into the world of immortals, where immortals, demons and Buddhas coexisted. With this super BT awesome system, he transformed from a newbie in cultivation to an unparalleled genius master, recruiting countless future powerful men and establishing the Immortal Demon Sect... Is the sect not big enough? We have a system. Let's expand it by 1.8 Million li first and use the excess as warehouses. Is the mountain protection formation not strong enough? Exchange some for the fairy world and cover them in layers. Are the elixirs of poor quality? My system automatically refines the elixir, and nine of the ten pills are the best! Whatever skills, magic weapons, or spiritual beasts, I have them all in this world, and I can have them even if I don't have them... (The 3G system is a scam. What I posted yesterday cannot be reflected today every time.)
