I Just Changed to a Summoner, and My Summons Think I'm Weak, So They Go Slay Gods

[Urban high martial arts + summoning + anthropomorphic characters + tycoon protagonist + lie-flat power fantasy + no saintly self-sacrifice]

Lin Feng transmigrates to a world where everyone changes class. He's the son of a Sword God and a top financial magnate, yet under the gaze of the entire crowd, he awakens the supposedly most useless F-rank class: [Novice Summoner].

The whole city laughs at him as a good-for-nothing young master, but Lin Feng throws his head back and laughs. “Perfect! Now I can go home and sponge off my parents with a clear conscience, living the carefree life of a spoiled rich kid!”

But then the experimental summon he just bought, a slime, suddenly gains sentience!

Disgusted by its owner's laziness and convinced he's brought shame on all slimes, it leaves him a letter and runs away in the middle of the night, heading straight for the forbidden Abyss!

[Your summoned beast “Little Green” killed an Abyssal Dragon, grasped divine-level Devouring, and evolved into the Lord of the End!]

[Your summoned beast “Little Bone” found its equipment too shabby, dug up an ancient god's tomb on its own, and rose to become the Undying Hades!]

While Lin Feng lounges on a luxury cruise ship with a glass of champagne, his summoned beasts kneel at his bedside, weeping bitterly. “Master, please level up again! We can't contain all this power!”

His Sword God father looks utterly stunned. “Son, you really haven't been secretly working hard?”

Lin Feng spreads his hands helplessly. “Dad, if I told you the summoned beasts trained themselves, would you believe me?”

Only then do everyone realize that this young master, who only ever wanted to be a wastrel, has long since become invincible!
