When Ning Shi returned to Duohuang, it was already 11 o'clock at night. Upon reaching the edge of the city, he found that a large number of slaves were still building the city wall.
Some of the slaves were in charge of mixing the clay, while others were in charge of splitting the clay into pieces and building them into walls.
Each group of slaves was followed by several fire-breathing lizards.
The fire-breathing lizard was an intermediate magical beast that could spit out extremely powerful flames.
After every small portion of the wall was built, the fire-breathing lizards would take turns to spit fire, directly burning the clay wall into a solid brick wall.
The city wall was built very efficiently.
Fox, the old Foxman, introduced, "Including the new Moon Elf captives, we now have a total of 130000 slaves. They're divided into two shifts, and they're building the city walls day and night."
