Gu Fan's blood is now very special. Once it flows out of his body for a while, it turns blue and loses its bloody scent. Therefore, Xue Wang did not suspect that Gu Fan's blood was the source of the blue reagent.
Only ten minutes have passed, and most of Dark City has been occupied by mutated vampires. Even if you hide inside a house, it cannot stop the mutated vampires from breaking in.
Everyone knows that if this continues, Tower of Darkness will also be breached under the heavy siege of the mutated vampires. That's why Xue Wang is tolerating Gu Fan.
Lord Xiong ordered someone to notify the Four Great Nobles to immediately escape into Tower of Darkness, to try to reduce the number of people outside as much as possible; otherwise, there would only be more and more mutated vampires. As for the commoners, sorry, you're on your own.
In the eyes of Organization X, as long as Organization X does not fall, Dark City can continue to exist, and commoners will still come.
