Monster Ender system [BL]

One day a very strong solar flare hit the earth destroying the entire atmosphere. In just a span of a year, the entire world was completely tormented by earthquakes and tsunamis killing almost half of the population. And when humans thought it was the end, the monster appeared. Undead and mutated monsters hunted down the remaining humans. Weak end up as the prey and the strongest rule. Lin Yunfeng, a 25-year-old construction worker, was pulled into the whirlwind of this world when he stumbled upon the Monster Ender system by accident. With a system and a small godly beast in hand, he embarked on his journey to be number one. Because only the strongest can make the rules. He wanted to be the one at the top just so he can restore the balance of this world.
