This is a story about a legend, of one that can never be forgotten.
Summer, first time down the mountains in 16 years, after being raised by his 3 masters and Fairy sister.

‘Why won’t you follow the Rules of society?’ The rules are the tool made by the strong, so I follow my own rules.

‘Why won’t you just use your brain instead of your brawn?’ Idiot! Have you ever seen anyone use their brain, to get back at an ant that bites them!? No, they just casually step on it.

‘Oh, everyone says you’re a first-class beauty huh?’ well, I’m sorry but even you are not qualified to be my wife. Only a ‘Summer class beauty’ is worthy enough!

‘My enemy is sick?’ Oh, don’t worry, even if you’re on your last breath and I feel it’s beneath me to slap shot you dead. I’ll just fix you up and then beat you!

‘Who am I?’

“I am Summer in the spring, the autumn, and the winter, I’m the world’s first above the heavens!”

Follow me, Summer Day as I step by step become known as the world’s first master, the world’s first doctor, the world’s richest man…… a lot of other world’s number one, but most importantly, The worlds happiest man.

“Is this really a f*cking cannon fodder counterattack system???” Zhou ZiRuo transmigrated into a game and became a shapeshifting, cannon fodder, baby fox demon.

As a new (male) fox demon, he thought his task was only to counterattack the gold-fingered, peerless, super explosively cool, iceberg protagonist.

But why did the iceberg protagonist seem like he was possessed by a death god, with NPCs dropping dead left and right everywhere he went?

Why must he help the protagonist investigate the incidents or else the counterattack percentage would fall through the floor, leading to his death?

As Zhou ZiRou wearily investigated the supernatural cases, at the same time, he walked down the grand path of counterattacking the protagonist and kicking him to the curb.

Yet no one knew that under the iceberg protagonist’s calm and proper exterior was a heart that was both kuudere and wicked.

System: Congratulations! The counterattack was successful!

Zhou ZiRou: You motherf*cker, you never said that I’d counterattack into the role of the female lead ahhh!!!
