Chương 223: Chapter 223 – Second Wave Begins

"These stones are meant to be pushed off the wall when the beasts reach it. It serves two purposes, the first is to kill some beasts, while the second is to buy a few more seconds for the wall. The wall is strengthened by a few sixth-rank formations that will help it endure the beasts' attack, but they will gradually take damage until they shatter, and the wall soon after. The costs are not a problem; the treasury of the city is linked to the formations."

The treasury had many Qi Stones of all qualities, and their combined worth probably reached over a billion medium Qi Stones. The weak link was not the speed at which the Qi Stones would be burnt, but the time the formations would survive the onslaught of countless beasts acting like rams.
