Invincible at the Start, the Empress Begged Me to Sell the Blind Box

Xu Qing travels through the fantasy world and is bound to the most powerful blind box system. As long as you sell the blind box, you can get a refund from it. Inside the blind box, there are elixirs, techniques, artifacts, and divine powers. As a result, all major forces went crazy. Empress: "Boss Xu, I have moved all the treasury just to buy a blind box. If it is not enough, my body..." Demon Lord: "I'm going crazy!! I'm going to refine myself and draw the blind box!!!" Emperor: "Oh, oh, oh, boss Xu, I am willing to surrender for the rest of my life. Please give me a blind box. I can't live without it." Saints, sons of gods, extraterrestrial demons, even the supreme immortal... Xu Qing counted the innate treasures, magical weapons, and chaos techniques that were constantly being accounted for and smiled slightly.
