Sorcerer in a fantasy world - Chapter 1 -

Kyoukai Senjou no Horizon chronicles the story of a futuristic civilization returned to Earth after constant warfare hindered them from traveling beyond the post-Apocalyptic Earth. At this stage, a small archipelago called the Divine States were the only hospitable land on Earth. In order to regain the space-faring technology they had lost after many years of war, they decided to recreate history with a book called the Testament as a guide.

It is the year 1648 in the Testament Era. Toori Aoi, Chancellor and Student Council President of the only academy on the airborne city-ship Musashi, faces the ten-year anniversary of the death of his childhood friend Horizon Ariadust in an accident. As he prepares to celebrate the occasion by proposing to P-01s (an automaton who looks exactly like Horizon) he discovers that his suspicion about P-01s’ appearance actually has a basis in truth; P-01s is in fact Horizon Ariadust, reborn into a robotic body. In addition to this, Horizon’s emotions had been stripped away and are now stored in eight powerful weapons called the Mortal Sin Armaments; which are now in the possession of key people in various established countries in the Divine States.

To retrieve the emotions of Horizon Ariadust, Toori Aoi along with his friends and allies begins a crusade against different obstacles as key events in history are recreated in a futuristic manner.

Li Yu transmigrated to a world of the cultivation and martial arts. He became the head disciple of a low-ranking sect.

An internet troll who wanted attention, the reader criticized his favorite web novel, saying: “The protagonist is dumb and the author is stupid.”

Author: “… Got it.”

Unfortunately for him, the author actually listened to his (troll) feedback. The formerly lighthearted tale of a cute harem master suddenly became super dark and edgy. The reader could only helplessly look on as the the protagonist was abused and betrayed, finally embarking on the road to becoming completely evil. Everything was a mess!

After that the reader transmigrated into a strange world. How come the person in front of him looks like the protagonist (evil undead version)? Just what is going on?!

Note: Du Zhe (读者 meaning Reader) and Du Ze (杜泽 the character’s name) sound almost the same

- Description from Novelupdates

The royal bastard of House Vasquer, Argrave, changed after his stay studying magic at the Tower of the Gray Owl.

The sickly man's awkward posture and cruel behavior have been replaced with a neat dignity and acerbic wit.

Though once listless, he now strives towards his goals with a life-or-death tenacity.

Most come away thinking he seems to know too many details about too much. Few can claim to know his motives or his goals.

Yet behind that confident appearance, the primary contributor for an open-world RPG's wiki battles existential dread and things far beyond his ken as he struggles to adapt to a grim, gothic fantasy world mirroring his favorite game.

The prospect of fighting against a world-ending calamity loses all of its appeal when it transitions from entertainment to reality.

Argrave is spurred towards unwanted heroism to preserve his life as he struggles desperately to keep this sinking ship afloat.
