Zero_Things

Haru was the best mage in the Japanese army. Building up a amazing reputation before deciding to give up his life in the military and settle down.

 His plans were cut short as he found himself in the body of a baby.

 He taught himself magic again from scratch before finding himself in a dire situation whilst on his first school trip causing him to give up on magic and take on the art of Chinese cultivation. 

His master was a soul fragment of an ancient cultivator who placed his soul inside of a golden ring in the shape of a dragons body.

 What kind of mysteries did this ring hold?

 And who was this cultivator who saved Haru from the brink of death?

The Legendary F Rank

"You're crazy, I never thought that anyone would be willing to do something like that let alone a human from some unknown planet in the lower realm. A word of advice for you, when you are in the tunnel make sure you kick the bombs out so they don't follow you to where you end up.

The last thing that you want to do is end up on another planet just to destroy it with the bombs that you tried to save your people from.

But I have a question for you now. How do you know that I won't go back on my word and kill all the people here as soon as you're gone? No one would be able to stop me if you go. What is giving you so much confidence?" Hanying asked as it seemed strange that Haru had gone from wanting to kill him just a few moments ago to entrusting him with the lives of all the humans on earth.

Goodbye.
