MTL - Doomsday: I Have One More Keyword Than Others - Chapter 23 The fighting style changed by the demon

I’m not a gamer. In fact, I barely touched games—never had the time or interest.I’m a 23-year-old college dropout, part-time construction worker, and full-time avoider of adult responsibilities.That is, until my little sister nagged me into trying a romance simulation game called Echoes of the Crimson Throne.I played it. Liked it more than I expected. I even completed it.And the next thing I knew… I woke up inside the game.Not as the hero.Not even as a love interest.I was now the personal attendant of Alice Draken—the villainess, the Prince’s fiancée, and the iron-fisted Ruler of the North.A woman whose downfall was guaranteed... unless I do something about it.

The tale of Oliver.
An orphan boy from a Mine, in 19th century Europe, filled with Magic.

In the vast and boundless continent Cangtu, there were ancient sects governing the Ten Old Domains, unworldly immortal clans beyond the Blue Sky, and primordial demon gods dominating the dark abyss that together created a great number of brilliant stories over the long course of the history.

In this very world, there was a boy, named Lin Xun, who embarked on his journey to the pinnacle of strength alone through cultivation and spiritual tattoo inscribing.

Escaping alone from the Mine Prison where he had been living since he was adopted by Master Lu, Lin Xun knew nothing about his identity but the little information his adopter, Master Lu, had told him. With two ancient spiritual tools Master Lu gave to him before the destruction of the Mine Prison, Lin Xun started his journey to Ziyao Empire, where he is supposed to find out the truth of his lost Spiritual Vessel and the person who slaughtered his family, leaving him orphaned.

Will he be able to unlock the mysteries of the two magic treasures, unveil the secrets of his identity and create a legend of his own?

In novels with a stud there is always a Senior Martial Brother like this:

In the early stages of the novel, his innate talent is high, his cultivation is good, his appearance is handsome, and he has an intelligent, cute younger Martial Sister as a fiancée.

In the middle stages of the novel, he is caught unprepared and defeated by a young disciple (the protagonist) in the sect who’s hardly remarkable at all. From then on, he falls from his godly altar and loses his brilliance. Even his young Martial Sister leaves him for someone else.

In the late stages of the novel, he continues to turn dark, going down the Demonic Path and becoming the major villainous boss. However, the protagonist still ruthlessly defeats him and his soul is eternally sealed.

Once Qin Mo opened his eyes, he discovered that he had become this Senior Martial Brother.
