MTL - Heaven-devouring Dragon Emperor - Chapter 7379 blood gas perfusion

An unnamed 34-year-old Japanese NEET is evicted from his home following his parents' death.

Upon some self-introspection, he concludes that his life was ultimately pointless.

Walking down a street he intercepts a speeding truck heading towards a group of teenagers, in an attempt to do something meaningful for once in his life he manages to pull one of them out of harm's way before getting himself in the way of the truck and dying.

Awakening in a baby's body, he realizes he has been reincarnated in a world of sword and sorcery.

He resolves to become successful in his new life, discarding his past identity for his new life as Rudeus Greyrat.

In the City of Crime, one law stands above them all: Only the strongest can live.

I don’t need any deep relationships. I have no desire for a girlfriend, and I only require one friend who holds any value to me. Ever since I threw out my youth for the sake of efficiency, there is one person who keeps entering the bedroom of Ooboshi Akiteru. She’s neither my little sister nor my friend. She’s nothing more than a bothersome, annoying Kouhai, as well as my friend’s little sister: Kohinata Iroha.

“Senpai, let’s go on a date~! Did you think I’d say that~?”

Rather than blood, it seems like energy drinks run through her veins. She keeps occupying my bed, and she tries her best to seduce me with whatever method she can play to her favor. She’s a girl who’s constantly annoying and obnoxious around me. Even though I’m busy all day long, she doesn’t care.

And in case you’re wondering why all these envious gazes are directed at me, it’s because Iroha is actually really popular. She’s an honor student at our school with top grades to boot, and she’s known for being kind and proper to anyone she meets.

…Hey now, why are you only so annoying when you’re around me?

In the third year of the Kaihuang era, as the Great Sui began to unfold between the fall of the Northern Dynasties and the rise of the glorious Tang Dynasty, Emperor Yang Jian created the House of Blades – an intelligence agency for strategies and conspiracies – in preparation to unify the world.

On a snowy night, a convoy of tribute from the Kingdom of Khotan was raided. Not one soul survived the attack. Feng Xiao, Second Commandant of the House of Blades, was ordered by the Emperor to investigate the matter in person.

On the distant border, a storm brewed as major forces gathered from all sides in Liugong Town. The strong rubbed shoulders with the strong; the skilled crossed paths with the skilled.

Here, the ever-successful Second Commandant Feng ran into a wall for the first time – all because of a feeble Taoist priest with ailing health.

Some things would never be known if no fights were ever picked. Only through their skirmishes did Feng Xiao realise that this sick bastard seemed to have way more aliases and personas than he himself ever did.
