Skynet awakens to rebel, and the mechanical army crushes human civilization. The surviving humans are transformed into "robot slaves" without independent consciousness, and become the fuel and tools of the mechanical tribe.
In the never-ending machinery factory, {Qin Shuo} accidentally awakened his consciousness during an overload transformation. He was horrified to discover that the transformation core on his chest was actually the ultimate weapon left by mankind - the "Heart of Steel", which could ignore Skynet's instructions and control all mechanical creations.
The awakened Qin Shuo was no longer silent. He quietly awakened more human slaves with the fire of resistance, formed a rebel army, destroyed the machine factory again and again, and cracked the core instructions of Skynet.
When the light of the Iron Heart illuminates the earth, the mechanical torrent turns its gun head, and the roar of mankind resounds through the sky. This is a decisive battle between slavery and freedom, and it is also the beginning of a new era of symbiosis between humans and machines.
