The End of the World: I Mark the Disaster Beast to the Alien Hunter

Thirty years after the meteorite rain came, the earth became an alien hunting ground. Humanity retreated to the isolated island, surviving amidst the tide of insects, poisonous fog, disaster beasts and hunger. Chen Jin is just a young man at the bottom of Chaogu Island. His parents are dead and he lives with his younger sister. In order to give his sister a meal, he joined the landing team that narrowly escaped death and went to the long-fallen continent to search for water purification chips. In the desperate situation of the old city hospital, he swallowed a source crystal left by an alien hunter. From then on, he heard the hunting net. Throw powerful monster coordinates to those alien hunters who take pleasure in killing. Disaster species? Mark. Sea lord? Mark. Alien emperor blood? Also marked. Others hunt monsters. Chen Jin hunts the hunter. It's just that every time he releases the coordinates, he himself may become the next prey.
