Lin Chen and Su Qingyue were ordinary students at Jiangcheng University, but due to a siege by alien beasts, they accidentally awakened the ancient protective power of the Chinese Dragon Vein and the Taiyin Spiritual Vein. In order to seal off the evil existence in the secret realm of the Yangtze River, the two sacrificed all their power and became "pulseless useless people", with only their personal jade pendants and silver bracelets hiding their secrets.
Just when they thought the crisis was over, an urgent report from the Wu League came: the number of strange beasts in the Yangtze River Basin increased sharply, their strength far exceeded before, and a deeper darkness was awakening. The two people who lost their psychic powers were invited to join the alien beast response team, tracking down clues in the ruins, and triggering dual-vein resonance in a desperate situation.
The jade pendant heats up to revive the dragon's veins, and the silver bracelet rings to summon the blessing of the moon. Can the former "Guardian of Jiangcheng" rekindle the fire of spiritual power? When the abyss crack spreads in the city, they can only use their twin veins as blades and the contract as a shield to continue writing the legend of protecting the city at the boundary between spiritual energy and mortal life!
