Dragon Loves Farming

I traveled through time and space and became a giant dragon to obtain a planting system. I originally wanted to live a leisurely life as a farmer, but the tattered hoe could actually cut iron like mud, and the alien Zerg were all killed after a spray of insecticide. What's more powerful is the seeds rewarded by the system. "Brother, the elves, the human empire, the metal dragons, the orcs... want to see you. I want to ask for a seed of Qiankun Creation, and I am willing to offer you my most beautiful princess." "I am the kind of dragon that lusts after beautiful women. Let them go." "By the way, Princess, stay and go away. This will allow them to plant potatoes."
