Having the Hauling Unit move into position ahead of time had truly been a wise choice.
By the time Gu Xi's forces took the city, the first few districts they had conquered had already been stripped bare.
Just as Gu Xi had requested, the Hauling Unit focused mainly on carting away the Wonder sections this time.
They did not take so much as a bit of the remaining construction debris.
They did not even hurry to transport the sorted corpses back, instead leaving them on an open patch of ground outside the city.
Under their handling, most of the black Longsword-shaped buildings in the city were dismantled. Their foundations were also dug up directly, and large quantities of half-metal, half-stone material were thrown outside the city.
The Architects who had rushed over temporarily examined the material and finally reached a conclusion.
It was the result of molten, high-temperature lava mixed with certain metals and forcibly poured straight into the earth.
As for what metals had been added, or what kinds of stone had been used, they had no way to find out.
The only thing they could confirm was that this material had extremely strong shielding properties.
