For the task arranged by the Grand Knight, Gu Xi was still very attentive.
After the Grand Knight left, he quickly arranged for two heroes to handle the matter, while he himself stood on the shore, observing and contemplating the water network defense line.
The Grand Knight only gave a reminder; Gu Xi hadn't figured it out yet.
But one thing was certain, the water network defense line was closely related to city construction. Gu Xi suspected that as long as the water network defense line was built, Yalidu City could gain four to five more large plots of land.
For Gu Xi, this was a huge supplement.
While Gu Xi was thinking, the progress of the project here saw the underground river's water slowly retreating a lot.
Gu Xi could see that in this underground river channel, many corpses had accumulated.
Because they had always been washed by the river's current, most of the corpses no longer had flesh, leaving only parts of the white bones.
