On the Battlefield of Ten Thousand Races, a Billion Citizens Help Me Become a God

After transmigrating to the battlefield of the myriad races, Lin Feng is trapped in a deadly abyssal miasma from the start. His beginner's protective barrier is about to shatter, and the System forces him to give up his soul and become a wandering undead. Others awaken mythical troops and peerless combat strength from the start, slaughtering their way across the battlefield. But the only talent he awakens is a [Spacetime Mailbox] that can open a tiny wormhole just three times a day? With death closing in, he writes a final letter in his own blood. He sends it, along with the high-dimensional energy core he risked his life to retrieve, to his younger sister on Blue Star. While others still cling to wooden spears and fight desperately against the insect race, he sets up a six-barreled Gatling gun and instantly grinds the swarm into mince with a storm of bullets. While others fight tooth and nail over half a moldy wild fruit, he monopolizes the entire server's market and reaps vast quantities of crystal cores without lifting a finger. When the gods of other races arrive with armies a million strong, seeing humanity as helpless prey waiting to be slaughtered, all the races tremble beneath the barrage!
