I, Chen Tian, the Primordial World's Gift-Bringing Boy!

After transmigrating into the primordial world, he becomes a dying flood dragon. He thinks he’s done for... Luckily, the Billionfold Return System appears! Anything he gives away gets returned a billionfold? Well, in that case, he’ll gladly take on the title of generous benefactor! Master Tongtian: “What the heck? Chen Tian actually gave me the supreme innate treasure, the Myriad Dao Sword? Say no more! Whoever messes with Chen Tian, I’ll kill the bastard myself!” Yuanshi Tianzun: “That’s nothing. Chen Tian gave me the Great Dao Origin Tree! It’s a supreme treasure on the level of Chaos!” Nuwa: “Um... He gave me the supreme Chaos treasure, the Skirt of Stars from the Myriad Heavens. Should I accept it or not?” Hongjun: “That’s nothing. Chen Tian gave me a complete Heavenly Dao Origin!” Chen Tian: “Don’t thank me. I just love doing good deeds! Want a supreme treasure or a spiritual root? Want unparalleled magical power or a thousand worlds? What are you waiting for? Send me your address!”
