MTL - Live Surgical Broadcast - v3 Chapter 2840 Wink at the blind

In the middle of a deserted island, a small boy wakes up with two sets of memories: one from his few years of life and the other from a man who lived to adulthood and achieved great things. When he least expected it, a powerful master appeared on the island and took him in as a disciple, revealing a shocking fact: magic exists in that world, and, thanks to it, humanity managed to conquer the galaxy.

After being summoned in this other dimension world, all of the people that were summoned had their classes awakened. As someone that doesn’t even know English, Kim Sunhyuk had awakened as the lone Dragon Rider. But wait, there are no dragons?!?! They looked down on him, shunned him for being worse than a regular soldier, and called him a dragon-less rider. But little did they know that he would soar the skies on one above them.

A cultivation story about how a declining sect is restored by a narcissist, a troublemaker, a meanie, an idiot, and a wimpy kid.
