Tennis collapse: My strength is the sum of the losers!

Beichuan travels to the world of Net King, and accidentally awakens the summation system.

He was in Qingxue, but was rejected by the old lady Ryuzaki Sumire.

The first grade can only pick up the ball obediently.

Beichuan started the road of challenge.

The more people he defeats, the stronger he becomes.

As the loser’s strength improves, it will be fed back to him.

Hundreds of people beheaded, thousands of people beheaded.

An undefeated legend of a great devil king was born!

Sumire Ryuzaki regretted it!

Tezuka: “Beichuan is actually the best candidate for the pillar of Qingxue.”

Atobe: “Why does the harder I train, the bigger the gap between me and Beichuan?”

Yukimura: “Kitagawa is the real god.”

Echizen Ryuya: “The talent of Kitagawa is above all others.”

Byodoin Feilu: “No one is Beichuan’s opponent, and I can’t beat him even if I have ten.”
