I Can Exchange It for All the Worlds

Travel through the Beiyan Empire and awaken the super exchange system. As long as you spend krypton gold, you can become stronger. Not enough cultivation? One hundred gems, give me a bottle of upgrade pill. No bodyguard? Ten thousand taels of gold, exchange it for me for Sword Master Genie. What, you all have martial arts spirits? Come on, system, I will give you all my belongings. Give me the Clear Sky Hammer, the Blue Electric Tyrannosaurus, the Seven Treasures Glazed Pagoda... All these martial spirits. I will scare them to death. Krypton's invincible creature never needs explanation.
