There's definitely something wrong with this murder mystery game - Chapter 880 - 729: Special Elf Bloodline_2

For the sake of his family, Ren embarked on the popular VRMMORPG, COVENANT, that used real-time in-game currency. But being a mediocre player who only knows how to gather information, he was put in a supporting role.

As the game explodes in popularity and every multibillion-dollar company invested in the game, things have turned for the worse for Ren. Due to the amount of information he gathered, the cheats, secrets, quests, and bugs he discovered, he was silent in fear of selling the information to the other guilds.

But given a second chance, he went back in time when his father was still alive and COVENANT was just in its starting phase.

This time . . . he wouldn’t be that guy on the side who gathered information from day in and day out for ten years.

Equipped with the games knowledge he accumulated, he will become . . . an Alchemist!

Chrono Mage? Djin Master? Summoner? Necromancer?
Chaos Lord?

What good are those?

Sure they’re powerful and rare classes and sought after by guilds, but it’s the alchemist who forged artifacts and concocts rare items and potions that gets the most coins at the end of the day!

It was better than being a blacksmith or a crafter! Plus, he could use all sorts of magic without limit to race and class!

It was the ultimate class! And no one even knows it!

Our straight (?) bottom woke up ten years into the future and found himself on the bed of his childhood friend… At the start, the bottom was shocked to his very bones, but he soon quickly accepted this premise and found the whole situation to be rather amusing. Precisely then, the bottom once again went back to his timeline — back to when he and the top were just platonic childhood friends.

Landmines include but are not limited to: Sweet & naive bottom, a president story, logic is dead, slow-progressing romance, the protagonist’s name has too many character strokes, the names are hard to pronounce, too many gay characters…
