The 27-year-old Zhou Xiang, chief consultant of the Earth Federation's Strategic Planning Bureau, was accidentally bound to the "Future Contract System" while studying mysterious alien signals. He can sign contracts with various intelligent beings and plunder talents, resources and loyalty. Faced with the infiltration and invasion of the earth by the void lords and their agents, he relied on the system to accurately grasp people's hearts and signed contracts with global elites such as political tycoons, business giants, and scientific research geniuses to form a contract chain network covering multiple fields. From the power game in the imperial capital to the exploration of the ruins in the deep sea, from the Covenant outpost in the asteroid belt to the secret base at the edge of the galaxy, Zhou Xiang leads his contract partners, relying on the power of the contract, Covenant technology and his own awakened Covenant bloodline, to fight against the void worms, void mother insects and the void lord's interstellar fleet, and finally eliminate the void lord. However, he discovers that a more powerful unknown force in the universe has quietly targeted the earth, and a new war is about to begin.
