I'm Upgrading My Shelter, and You Talk to Me About Spiritual Energy Recovery?

If we don't say it's the end of the world, why do everyone say the spiritual energy has revived? Something is wrong, Zhao Xian seriously doubts that he has traveled through time and space! The friends around me awakened their blood spiritual roots one by one. Why is it my turn to get nothing! Fortunately, I opened the Intelligent Brain in time and can upgrade the shelter infinitely. Ordinary shelters—alloy shelters—titanium shelters—vibranium fortifications—fortresses... Ordinary protective clothing—composite protective clothing—exterior armor—nano mecha—Iron Man suit... Van—armed off-road vehicle—fully armored combat vehicle—doomsday chariot—cavalry shuttle... I build when others are cultivating, and I farm when others are awakened! The end will eventually come: fog, space rifts, crypt invasion, ghostly resurgence... The introduction is weak, please read the text... This novel and its characters are purely fictitious.
