Reborn Goblin, Picked up an Elf Mother at the Beginning

[Reincarnated Alien Race] + [System] + [Decisive Killing] + [Monster Evolution] As soon as I was reincarnated into a goblin, my elf mother tried to strangle me to death! Chen Chen, the top killer in his previous life, opened his eyes and faced a bloody birth chamber, hungry fellows, and adult monsters blocking the exit. Newborn body, defenseless? Then use the gravel as the blade and the bones as the steps! The same race pounced on him and cut through his brain stem; the mutants sneaked in and nailed him to death with his backhand; the adult goblin insulted his mother, stabbing him blindly and breaking an arm! Awaken the King of Sin system and obtain the concept-level talent "Swallow". Kill enemies to gain attributes, slay monsters to gain skills, devour blood, and evolve through levels! Others waited to be fed when they were born, but Chen Chen was killed in the birth room after he was born. He originally just wanted to live with his mother, but all the people in the abyss regarded him as a monster. Since the weaklings have to be slaughtered by others, then he will devour and crush them all the way until he reaches the top of all races! But when the Goblin General saw the mark on his chest, fear appeared in his eyes for the first time...
