Apocalypse of the Stranger

In 2065, due to the serious aging of the global population, the global birth rate fell below 2 million per year. Due to the sparse population and resource shortage, human science and technology began to stagnate, so humans established a mysterious world organization and established a human genetic research base under the Arctic ice, developed the fifth generation of test-tube babies, and began to study human anti-aging and super soldier programs. However, an unexplained serum leak occurred, and within just six months, human society began to collapse. Globally, 80% of humans and 95% of animals, plants and insects have mutated due to serum virus infection and become skeletons, monsters and species. But as with everything in the world, there are always exceptions. After being infected, some humans not only did not turn into terrifying skeletons, but instead gained superpowers; animals also began to have leader-level skeleton monsters with high intelligence and the ability to command their own kind to fight; after insects mutated, most of them were leader-level skeleton monsters with medium intelligence, and were keen on moving in groups; plant mutations generally formed skeleton species, and there were also leader-level skeleton species that could move after being infected with rhizomes, had a certain IQ, and could command their own kind. These special mutants were collectively known as alien skeletons. What's even more amazing is that by killing the aliens, skeletons, monsters, and species, and absorbing the bone marrow fluid or root fluid from the infected parts, you can evolve your abilities and acquire corresponding magical abilities. However, as time goes by, the IQs of animal and plant aliens are also constantly improving. Whether humans can survive this catastrophe and what the future of the earth will be like has become a mystery.
