Black Skeleton Mecha Warrior

After the meteorite rain fell on the earth, the mysterious outer space material "black skeleton" began to pollute life. Animals, humans and deep-sea creatures in the city mutated into monsters one after another. In order to save his sister Xiao Xiaoman, Xiao Jin, a young man from an underground maintenance shop, fused with a black star skeleton fragment and obtained the black and silver living mecha "Black Skeleton Arm" that can cover his whole body. However, this power is not a gift. Every time Xiao Jin transforms, he gets closer to the monster. The Special Bureau needs him, monitors him, and is also afraid of him; monsters are not pure enemies, but life on earth distorted by star skeletons; Wang Cheng, a survivor of the old experiment, appears with another homologous power and tells Xiao Jin: Humanity may not be worth saving, and star skeletons may be the future of evolution. From the ruins of the subway to the crow tide at the airport, from the beast tide in the dark zone to the gate of the deep sea, Xiao Jin gradually understood during the battle that the real enemy was not only the mutated monsters, but also the unknown existence watching the earth behind the door. He was not a born savior. It's just that every time disaster strikes, there are those who persist for one second longer than despair.
