[Beast control + counterattack at the beginning + god-level management + information gap crushing]
"I was ridiculed and expelled from the academy just because I asserted that mud monsters can become gods? I changed hands and activated the mythical beast system and opened a pet shop - millions of slimes were scolded as a black shop, but I pointed at the evolution diagram: [Infinite Swallowing·Lord of the End]! Millions of little carps were ridiculed and thought they were crazy about money, so I showed my ultimate form: [Leaping the Dragon Gate·Ancestor Dragon]!"
"The genius who laughed at my madness and the mentor who abandoned me like a pair of worn-out shoes is now kneeling outside the store and begging me to sell the most rubbish pet beast. They will never know that what I am selling is not a pet beast... But the god who will control the laws of the future!"
