Just Don't Die, That's All [Quick Transmigration]

My name is Shen Anchuan. My desire to make a wish come true was so intense that I became bound to a System. The System said that if I completed my missions, it would give me a chance to make my wish come true. I agreed. It's been three days since I accidentally got on this pirate ship, and I want to cry. I'm a blubbering potato. Not only am I crying, I'm cursing too. That big trotters of a System tricked me. It waited until after the contract was signed to tell me there were ten missions. If I'd known, I might as well have gone looking for the Dragon Balls. At least once you'd collected all seven, you could summon the Divine Dragon. Bottom-centered, 1v1. The top in every world is the same person. Every world is an alternate universe. How alternate depends on how far my imagination can go. First-person narration.
