Rise of the Weakest Martial Artist Immortal

When the world of Darkness was in danger, the God of Martial Arts and the Goddess of Magic decided to summon the 5 strongest people from their respective worlds to save the world that was in dire straits. Subsequently, two were summoned from the worlds of Martial Arts and two from the world of Magic. The former summons were Murim and Cultivator while the latter were from High Fantasy and Magical realism. However... When it was time to summon the fifth, a mistake happened because of the confusion between the two Gods. And because of this mishap, a weak immortal from Earth was accidentally summoned instead. He was an immortal named Xian from Earth. With no Job class, no cultivation, and no murim martial arts, he was the weakest as he was an immortal that only mastered martial arts from Earth. Unfortunately, when the gods who accidentally dragged Xian into their problems, they were quite useless. He wasn't given with any powers and was left to survive in the harsh world on his own. Reincarnated into a baby, he knew that with his limited knowledge, he would never be able to survive this world closing on its doomsday. But he had not wished to die, he desired to survive!
