The "Dragon Vein Tree" guarding the lifeblood of Chang'an City suddenly rusted. Shen Tu, the chief craftsman of the Chief Executive, unexpectedly discovered that behind this "plant plague" was a shocking chess game jointly set up by the "Sand Boat" civilization in the Western Regions and the powerful clans in the DPRK.

However, when he truly integrated into the huge consciousness intertwined with trillions of roots, an even more shocking truth emerged: Chang'an City's "self-awareness" had long since awakened, and it believed that humans were the root of the disease that needed to be eliminated in this city.
