Summoning Bone Dragon in the VRMMO

In reality, he's a nobody trampled underfoot—no background, no connections, no luck, struggling just to survive. But when the whole world logs into that virtual MMO, all the rules are rewritten. Here, the strong can run rampant while the weak are left to be slaughtered? No. He's determined to carve a bloody path from the very bottom of this virtual world with nothing but his bare hands. No talent? Then he'll fight with his life on the line. No backing? Then he'll become his own backing. When everyone thinks he's just another cannon fodder—the weakest person has already reached the pinnacle of the world. Reality is cruel, but the virtual world makes it possible. This time, the weak will no longer stay silent. — Description from novelcodex.org
