Harry Potter: A Certain Ancient Rune Professor of Hogwarts (TL) - Chapter 713

Kai of the Sorcerer’s Tower is one of the last mages left, barely surviving in a world ruled by creatures of the dark — where the era of mages ended, and most of the lands got contaminated with dead mana. To save his world and fulfil his master’s last wish, he put himself through a forbidden ritual, risking his soul being ripped into pieces to make his way into the past. In an era with abundant mana — an era yet to enter the Golden Era of Magic. Things go wrong, of course, as they always do, and he finds himself thousands of years before the world fell to mana contamination — in the body of a young lord, Arzan. All is not well, though, as the young lord was murdered by someone right at the cusp of a beast wave threatening the territory, while larger threats loom on the horizon. There was a lot to do for Kai to regain his former strength in this time of primitive technology, but then again, he might just be able to change that.

In the previous life, he was in the shopping mall, and he was unwilling to die from a terminal illness, but was taken to the King Kong Temple in the prosperous world of martial arts by a Buddha statue of the medicine master, and was reborn as a medicine monk.

In this life, he only wants to live forever, to practice Buddhism and not to seek liberation

However, he unexpectedly discovered that with the blessing of Medicine Buddha, the mantra can turn legends into reality, and their power will be greatly increased.

The great light mantra, transcends the soul and goes straight to the bliss of the Western Heaven,

The mantra of clearing the heart, clearing the mind and calming the spirit, the mind is like still water,

Rejuvenation mantra, heals injuries like a god

……

He was even judged to be a waste of martial arts, but with the help of Medicine Buddha, he was able to practice Buddhist martial arts to the legendary realm.

Originally, I wanted to cultivate various medicinal materials, practice martial arts, practice Buddhism, and live in peace in this top sect Daxueshan King Kong Temple.

But I don’t want to, at this time, the Dagan Dynasty has experienced prosperity for thousands of years, and it has come to the moment from prosperity to decline.
