Outside, the intelligent brain, having heard the conversation between Chu Mo and the Demon Lord, curiously asked, "Why do you spiritual beings who cultivate have to undergo tribulation? Like me, as long as I find better materials, I can directly upgrade myself."
Faced with such a question, Chu Mo could only smile helplessly.
The intelligent brain continued: "However, come to think of it, it can be understood. Each of my upgrades doesn't bring me greater progress, just an upgrade in equipment. It can make my shell more solid and defense stronger. But it cannot make me like you spiritual beings. Once upgraded, you possess higher-level strengths. In that case, you experiencing Heavenly Tribulations can be understood."
Chu Mo nodded; he thought that the intelligent brain was simply an extraordinarily good partner because this guy was smart enough!
