Karl Wagner is a disgruntled middle-aged instructor at the Bundeswehr Command and Staff College. He finds himself concerned about the direction which the German nation is headed in—just as he is killed by a terrorist attack. Only to awaken and find himself reborn as an infant, Bruno von Zehntner, the youngest son of a noble family renowned for its part in the German war industry a few years after the founding of the German Empire. Bruno, as he is now known, desires to rewrite history and ensure the German Empire emerges victorious in the coming century. And in doing so, finds himself entrenched in a world filled with Blood and Iron!

Traveling to the wizarding world, Eli found that he was an Eternal.

Life is infinite, life is immortal.

“What? The talent is very poor, then I will meditate for ten years, centuries, and thousands of years, and I can always meet the promotion requirements.”

“This skill is hard? Oh, let me study it for decades to see if it’s really that hard?”

“Consuming life force, improving mental force, and this kind of good thing.”

“The enemy is here? Oh, let me find a place to hide for a thousand years, until his lifespan is exhausted and his mental power dissipates, and then I will come out again, free and endless void.”

…

This is the story of an immortal who lives in the wizarding world and then kills the endless world.

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.
