Are All the Delivery Guys in the World Getting Stronger by Relying on Rewards?

After delivering the last order late at night, Li Yang wanted to log off and take a rest, but because of his slowness, he took a strange order. As expected, something unexpected happened. A blue light flashed and he traveled to a different world. Only then did he realize that the "Zhutian Takeaway Company" recruitment resume he submitted three years ago turned out to be real! From then on, Li Yang became a cross-border delivery person across three thousand dimensions. Send spiritual food to the swordsman in the world of immortality, and get the "Sword Controlling Technique" reward; send barbecue to the elders of the dragon clan, and harvest the dragon's blood to cleanse the marrow; send afternoon tea to the princess of the magic empire, and unexpectedly get the forbidden spell magic book; send supplies to the base commander in the doomsday world, and get S-level power crystals... Every takeout order is an adventure. Every good comment makes him stronger. When Li Yang rode a giant dragon to deliver food, held an artifact to clear the way, and stepped on the void to travel through the planes, a legend was circulating in all the worlds—— That guy who delivers food is tougher than the customers! From a useless delivery boy on earth to the strongest delivery king in the world, Li Yang just wants to say one thing: Bosses, remember to give us five-star reviews!
