A man reincarnates in the body of a boy who suffered a tragedy, only to realize that he is in the world of My Hero Academia. What's even stranger is that his quirk seems to have the abilities of Nen and Haki.

Today’s headlines –
   “The Malaysian Master has broken through nine products and fought the world!”
   “The pony master is the best, sweeping Eurasian!”
   “Joe’s helper once again, suspected of nine major masters!”
   “The god of the gods is not old, the global master list re-enters the top ten!”
   “…”
   Looking at a piece of news flashing, Fang Pingxin is so tired, this script is wrong!

- Description from 69shu.org

Four years ago, Kazuma Kannagi was defeated by his cousin Ayano Kannagi for the right to be the successor of Enraiha, a sword passed down in the Kannagi family. His defeat, along with his lack of talent for En-Jutsu, the fire arts, the Kannagi’s specialty, resulted in his banishment from the family. Now, Kazuma returns as Kazuma Yagami, a skilled master of Fū-Jutsu, the wind arts. At the same time, a number of murders at the Kannagi residence perpetrated by a powerful Fū-Jutsushi cast suspicion on him.

Volume 1-6 makes up the main story. Volume 7-12 are various short stories, also known Kaze no Stigma Ignition.

Note: Only v4 epilogue remains untranslated for the main story.

Qin Huai crossed into the mysterious fantasy world where demons were rampant and heroes were rising. He had no background or cultivation qualifications until the day he became a medicine store apprentice and started to cultivate with his fellow apprentices.

He found that the experience orbs actually fell out of his master and brothers.

He learned to grind medicine with his brothers.

“Ding! ‘Medicine Art’ Experience+3!”

His Master and brothers practiced martial arts.

“Ding! You picked up an ‘Essence of Qi Cultivation (White)’, ‘Qi Cultivation’ experience +3!”

He killed the bandits in the mountains and picked up their cultivation.

“Ding! ‘Astringent Breath Technique’ experience +13!”

His master said that the technique was not good at attacking, had a cultivation limit, and could only prolong life.

But when Qin Huai picked up the experience until the Astringent Breath Technique was 50 times stronger, his body took a tremendous change. A gentle push of his hand was like a wave. He could now both attack and defend.

People said that when two kinds of cultivation methods clashed, continuing to cultivate would lead to the death of the cultivator.

However, when Qin Huai picked up experience and directly skipped the cultivation process, he found there were no side effects at all!

When Qin Huai practiced more and more cultivation methods, he suddenly found that those methods interacted with each other in his body and became stronger skills.

…

Qin Huai, who could pick up experience, began to wander among the major powers.

He saw flesh growing from white bones and the dead revived.

He saw demons cooking 10,000 people and exuding extremely evil energy.

He saw the Buddha statue chanting in the temple. Sanskrit sounded like a mantra.

Qin Huai silently picked up experience in order to settle down in the chaotic world.
