Online Games Descend into Reality, and I'm the World's Only Immortal Cultivator

[Traditional MMORPG + traditional fantasy. This is my first attempt, so please be patient.]

A mythic game descended upon reality, forcing the entire world to fight monsters and level up to face the disasters.

It was a disaster, but also an opportunity, and the dawn of a new age in which nations would vie for supremacy.

Li Jiang, a professional player on China's server, had been full of ambition three years ago. Leading the Dragon-Slaying Squad, he was invincible and created countless legends.

Just as he was at the peak of his fame and about to compete for the highest honor in professional gaming, an accident knocked him from his pedestal. He vanished from the gaming world.

Now that the game had become reality, with the nation facing the dire threat of annihilation, the country's leaders stepped in and found the once-famous professional player.

This time, Li Jiang would not only reclaim the glory that belonged to him, but also investigate the accident from three years ago. He would settle every grudge and repay every grievance.
