One Piece: New Order - Chapter 55: Sakazuki vs Whitebeard

Silas Blackwood wakes up with a machine in his chest – his missing mother's parting gift to help him survive the war with the Fae. This “system” grants him bizarre abilities: neuromancy (magic of the mind), biomancy (magic of the body), and essomancy (magic of souls and essences). Oh, and it fused a leviathan's mana core into his body. Because why not become part sea monster?At Arcanium University, a military boot camp churning out mage knights, Silas finds himself targeted by rich brats who think being born with a silver wand up their ass makes them special. When they leave him for dead, Silas decides it's time to show these spoiled kids what real power looks like.As Silas grows stronger, he discovers he can upgrade himself by absorbing essences from magical beasts and demons. Just when he thinks he's got a handle on things, Silas learns his mother's alive, and now he's got a new mission: a rescue that'll take him and his friends straight into the depths of Hell.

Being able to see into people's past has no real appeal for the teenager this story is about, letting him use it only as amusement and to show off when he was drunk.Never watch into someone's past beyond a superficial level.Never try to find out more than you should.NEVER. EVER. LOOK. INTO. THE. FUTURE.But everything changed the moment he was forced to look into the future, was forced to investigate a murder, and was forced to make the acquaintance of the victim's twin brother('s fists).The more time passed, the more it appeared that the primary reason for this murder wasn't a local problem, but a global one.This single, marred corpse was the beginning of a threat that would shake the world.(MC looses a screw when he enters the prison)BL, first-person view; MC is shuo (perhaps even a reversible couple); love interest falls in love first; both MC and ML are straight, mutual bending, Enemies to Lovers

He was the guardian with the most powerful talent of this era!

However, no one knew that he had a second template. His swords could slash through the flesh of his enemies and his soul could besiege the spirit of gods!

The others might have seen an obese Sword Saint before, but they definitely had not seen a full time meat shield whose attack was through the roof!

The nuclear holocaust which caused the collapse of the Old Times on Earth should have wiped out all human life on the planet. Yes, the gods set up their beautiful Elysiums to provide sanctuaries for their chosen, but by all rights everyone outside the elysian lands should’ve perished long ago. Yet somehow, human life still managed to persist, even in the deadly, mutant-infested wastelands.

Cloudhawk was a young scavenger who dreamed of being as free as the hawks in the skies, yet seemed destined to live out his life scrounging for scraps in the wasteland ruins. Fate, however, is ever-fickle. A chance meeting with a ragtag group of mercenaries changed the trajectory of his life, bringing him into a world with mutants and metahumans, demonhunters and godslayers, and even gods and demons. Cloudhawk would find his own place in a world that was far greater than he had imagined, find his own path between the zealous light of Sumeru and the whispering darkness of the Abyss… and one day, he would find that even gods may fall.
