Three hundred years ago, the sea was polluted due to the selfish behavior of a shameless race. Countless creatures in the sea suffered a devastating blow, and eventually the sea changed. And the first one to bear the brunt is the race that is the source of all disasters. That race is located in an island country. Countless mutated sea creatures rushed onto the land and began to kill wantonly. Their weapons had little effect on these mutated creatures. Some of the extremely powerful mutated creatures could resist the most powerful human weapons. Under their leadership, within half a month, the country was captured by these mutated creatures and turned into a huge beast's nest. As time went by, this mutation began to spread to all continents, and the creatures on the land also began to mutate. The entire planet became perilous, and the living space of humans was compressed. In the struggle with alien beasts, the number of humans in the world was greatly reduced. It was not until a substance called Lingyou was discovered that humans once again had a chance to return to their peak!
