Powerpuff Girl

This was a world where martial arts thrived and everyone would at least dabble in it.
Schools did not test the student's ability in mathematics or languages but in martial arts.
Just before his graduation, Lin Bai had awakened the 10000x Rebate System.
Whenever his contractee grew, he would be able to get the same growth bit at a multiplied amount.
Lin Bai quickly contracted the beautiful genius triplets of his school.
“Contractee Su Qing has consumed the Body Tempering Elixir and has raised her vitality by 10 points. 100x rebate activated. Your vitality has risen by 1000 points.”
“Contractee Su Lan has successfully mastered the A-grade Mountain Splitting Palm. Her palm force has risen by 5 kg. 1000x rebate activated. You have received the Sky Splitting Palm and your palm force has risen by 5 tons.”
“Contractee Su Zi has obtained the bones of a Fierce-grade beast. Her foundation bone has evolved into the Warrior Plane. 10000x rebate activated. You have received the bone of a Legendary-grade beast and your foundation bone has evolved to the Grandmaster Plane.”
“Lin Bai has reached a height that I’ll never reach,” said Su Qing.
“Sis, don’t tell me that you like Lin Bai? Su Zi, you too? But, I was here first…” Su Lan pouted.
“Umm… So, should I call you brother-in-law or hubby?”
Lin Bai looked at the three sisters arguing in the bed and grinned. “Only a child has to make choices. I’ll take all three of you.”

Contracted The Beautiful Triplets And I Gained The 10000x Rebate System

"If we don't die, the entire World Number One will be destroyed."

The Ancient God said, "If our world is destroyed, we will also perish."

" The Chaos Technique is a supreme saint-level art. It can survive in chaos. However, the Chaos Treasured Scriptur is rare."

The Ancient God added, "And the Chaos Treasured Scripture can only save a small number of people."

Lin Bai nodded with deep feelings.

In other words, even if they saved themselves with the Chaos Treasured Scripture, what about the others?

Moreover, the more advanced it was, the more difficult it was to master it. Not everyone could do it.

If only a few people fell into chaos, what was the point?

The entire world would no longer exist.

"Then, is it possible to find a way to save this world from extinction?"
