Awakening a Collective of Battle Power from the Start, I Am Invincible!

Ye Kai awakens an ability from the start, instantly gaining the combined combat power of the entire world. That means the fighting strength of every person on Earth, along with all their abilities. His omniscience reveals that his usually timid little brother is actually reborn, and was killed in his previous life while being hunted over a woman. His adorable little sister, who is always sweet around him, is actually the Holy Maiden of the Heaven's Sacred Gate and ranks among the top ten beauties. His father, who's always away on business and afraid of his mother, is actually an SSS-rank esper who pretended to be an ordinary person to hide the truth while raising them. Even the grandfather he has barely ever met is a pillar among the world's most powerful fighters… Fine, fine, so that's how we're playing it? Then I'm in too!!! If the older generation messes with the younger, I'll mess with the even younger ones. Little brother, little sister, sorry, but Dad and the others started it! And so… “What? Little bro's about to get a lucky break? Beat him up first and crank up the difficulty!” “What! Little sis wants a boyfriend? Beat the guy half to death, then beat him half to death again, then keep beating him half to death…” Until one day, Ye Kai's secret was exposed. “Little bro, little sis, hear me out!”
