Mysterious Revival: The Game Weirdness

I just don't understand. Why would an author, who could create a completely new ghost for the protagonist, kill a very responsible person from the original work? Is he mentally disturbed? There are so few people like Ma Jun in the original work, why? I just can't figure it out!

The protagonist is mentally unstable; as expected, his excessive abilities are balanced by his boundless intellect.

Ghosts are scary, but you've turned them into entertainment.

Don't underestimate your combat strength, or you'll be wiped out. Even the minor characters in some clubs have level three domain and level four or five abilities.

Decreased intelligence... Morally depraved.

The author has a good imagination and the subject matter is interesting, but the author lacks life experience, and the plot is too far-fetched. A student just walks by a supermarket, bumps into the supermarket owner, and immediately asks for ten million and a gold box. The supermarket owner believes him and agrees, and then they go into the supermarket together to catch ghosts. Was this a decision made on a whim?

The ultimate evil is idiocy. Only when idiocy becomes commonplace, and everyone acts like a fool, will there be nothing to fear.

If you're going to attack someone on WeChat Moments, just get straight to the point and don't beat around the bush. A lot of fanfiction is full of fluff and then they attack on Moments first, all while claiming they don't want trouble. If you encounter Jiang Shangbai at headquarters, just take him down or go directly to Fang Siming for a fight.

The writing style could be better; some parts are stiff. Please don't pressure the protagonist in this "Mysterious Revival" fanfic. We're here to see the protagonist wreak havoc; the later parts of "Mysterious Revival" are too depressing.

Was there a game-related ghost in the original work?
