“I am an evil god. Would you like to make a contract?” In “Phantom Heroes Online,” a VRMMO where in-game currency can be converted to real money, a man, worn out by society, decides to quit his job and earn a living through gaming. In this fantasy world of swords and magic, players contract with advanced AI NPCs, aiding and nurturing them. The protagonist, Zephyr, whimsically tells a young girl a lie, claiming to be her savior. Believing Zephyr to be the “god who rescued her from despair,” the yandere girl transforms into the formidable “Reaper Loli,” a top-tier berserker feared as the “Fanatic” across the continent. She rises to become one of the game’s top players, dominating the leaderboards. Unbeknownst to Zephyr and the other players, their actions in the game are actually leading to saving of another world.

In a world where reality shifts with every roll of the dice, a man daily partakes in an extraordinary game with the gods, his actions dictated by his decisions and the face of the dice. He takes great joy in this game until the tables turn, and he himself becomes a piece on the game board. Now, the dice are in his hands, and it’s his turn to shape his own destiny. It’s time for the Snowman to play his part.

After suffering from a heat stroke while working under the scorching heat of summer, Lu Zhou, a hardworking but poor university student, somehow becomes the owner of an advanced technological system. With the cheat given by the system, his university life changes overnight.

A Master’s degree? Easy.

PhD? Not a problem.

From a nobody, he quickly becomes a huge celebrity in the world of science. With the missions given by the system, he is on his way to winning a Nobel Prize.

“System, can points be exchanged for money?”

“No.”

“F**k, what use are you then!?”

“This system will make you the ultimate scholar, the kind that lords over all of humanity. What use will money be to you?”
