A sports idiot travels to the world of Prince of Tennis.

Poor talent?

It doesn't matter, the double return system allows you to show off, directly bind to the protagonist, and double the return strength.

"If everything can be bound, why can't we bind Nanjiro?"

[Nanjiro is the boss, no less than the son of luck. ]

"Ryoma, you're nine years old and haven't even started the Thousand Hammers Training yet. I'm deeply worried."

Many years later, after leaving the professional arena, Delongma wrote a book titled "The Story of My Brother Pushing Me to Achieve Growth"

(There is no female protagonist in this article!)

Takahashi Hikoichi travels to the world of Prince of Tennis, joins Rikkai University at the beginning, awakens the idle system, and becomes stronger just by lying down.

"After a day of idle time, my tennis skills have become roughly proficient and I am now at the regional level."

"After a week of playing, my tennis skills have been perfected and I have reached the Kanto level."

"After a month of playing, my tennis skills have reached perfection and I am now a national-level player."

……

"After a year of playing, my tennis skills have reached the pinnacle. I have realized the unity of man and nature, created my own magic skills, and have world-class strength."

While others are training, he lies down!

I thought he was just a loser, but I didn't expect his strength to increase instead of decrease.

Everyone was shocked!

He became a legend at Rikkai University and reached the pinnacle of the tennis world...

Wouldn’t it be a shame if you didn’t play basketball when you came to the world of Slam Dunk?

There is no first in literature and no second in martial arts. Once you embark on this path, you must reach the pinnacle!

A nerdy otaku, who was using a mod to play NBA, traveled to the world of Slam Dunk and became the legendary genius Sendō Akira. The otaku's dream is to get something for nothing, but when he traveled back in time, Sendō was still a baby. Perhaps it was fate that brought him a bug from the game, and thus, Sendō once again rushed to the pinnacle of basketball.

Coach Takaoka roared again: "Sendoh! How long are you going to stay in a daze!"

Xiandao covered his head and sighed: "I'm just a homeboy."

Mu Yue traveled to the world of Naruto and became an ordinary chuunin teacher at Konoha Ninja School and a member of the Root Organization.

Fortunately, after awakening the teacher system, you can become stronger by teaching.

In order not to become Danzo's consumables, Mu Yue worked hard to teach and increase her strength.

"Complete the teaching rated A for the first time and receive the reward - mastery of fire attribute chakra properties change."

"Under your guidance, this disciple has worked hard to practice, and his overall strength has been greatly improved, and he has been rewarded - the Immortal Human Body!"

From then on, there was a teacher in the ninja world who only wanted to make his students strong.
