Drained of Vitality? I Become a Saint by Devouring All Things

During his college entrance examination physical, Lu Zheng is diagnosed with “depleted vital blood,” becoming a laughingstock across the internet. His fiancée even publicly breaks off their engagement. He thinks he's destined to be a worthless nobody for the rest of his life, unaware that the hardest bones of the human race are sealed within him. At the brink of despair, he awakens the forbidden technique, Ninefold Body Tempering Art. While others spend ten years in grueling cultivation, all he has to do is kill an enemy to instantly extract and devour their vital essence and beast cores, forcibly raising his limit. His body is ten times denser than those of others at the same rank, and anyone with fewer turns has their combat strength reduced by thirty percent in his presence! Bullies pick on him? One punch caves in their chest! A financial conglomerate tries to crush him? He storms their manor alone on a stormy night, devours a century-old blood ginseng to break through, and pulverizes their D-rank patriarch from head to toe! When global financial conglomerates collude with exotic beasts and try to raise humanity like livestock, Lu Zheng smashes their rules with his iron fists. At the very front of the beast tide, he transforms into a Taotie and devours the life essence of Sea King Beasts. Bursting through the belly of an exotic beast and tearing his way into the open, he casually smashes an airborne A-rank expert into a rain of blood. The truth has always been within reach of a fist! When humanity faces the apocalypse, everyone thinks the sky is falling. That is, until Lu Zheng strides through the air and punches a ten-thousand-meter rift in the heavens, reducing the arrogant Holy Lord to nothingness. He looks at the global power rankings. “Now, is it my turn to make the rules?”
