Story of: I, an emotionally flawed person, seek redemption at Hogwarts

[HP Fanfiction] Alias: It's not easy to be a reincarnated wizard, wand in right hand and gun in left hand. The emotionally defective No. 13 died in an empty and cold ward. The emotionally defective Glenn Hawthorne was born in 1979. He longed for a peaceful life and reincarnated into a new world with family, friends, and everything a normal person should have. But a sudden attack shattered the peaceful life he was enjoying, and Glenn discovered the secrets hidden under the surface of this world. Magic? Alchemy? Obscurus? What are these magical and magical things? Glenn doesn't know yet. But as a killer in his previous life, he developed some interest in this. In order to seek revenge, he chose to enter Hogwarts School of Witchcraft and Wizardry. A former professional killer who has mastered modern killing techniques and is keen on manufacturing, modifying and collecting hot weapons, what kind of sparks will he collide with this magical world after learning the two skills of magic and alchemy? "I just want to live a stable and peaceful retirement life, but you disturbed me." "Choose a way to die." Glenn said this expressionlessly, with the gun in his hand already loaded.
