The entire cave was more or less as Qian Ying had described it: a trench about ten meters long, much like a battlefield trench. It was over two meters deep but less than a meter wide. The soil on both sides had been compacted solid, eliminating any risk of collapse.
Foxholes had been dug into both sides at the center of the trench. They were not the shallow sort that could hide only one or two people, but large, deep ones supported by wooden beams. Each foxhole could easily accommodate thirty people.
To ensure sufficient oxygen, several ventilation holes had been poked through using narrow tree trunks. This allowed air to circulate without letting mosquitoes in.
Tree trunks were first laid across the trench as supports. Then more than ten giant crocodiles were caught and pressed over the trunks before being covered with soil, leaving only the skin on their backs exposed. The purpose was to use the crocodiles' defensive capabilities to prevent the mosquitoes from charging into the trench.
Martial Artists were remarkably fast and skilled at this sort of work. The foxholes they built were also extremely level. The entire project took less than half an hour to complete. When survival was at stake, their speed was simply astonishing.
During this time, Qian Ying continued slaughtering mosquitoes from time to time, pulling them into his domain one by one and killing them.
"All right, everyone, get inside," Qian Ying called out. He spread his domain and cleared away the mosquitoes.
Once the Martial Artists entered the foxholes, only Qian Ying and two Xiantian Martial Artists remained outside. One of the three was responsible for lighting the half-dried deadwood, branches, and leaves, producing thick clouds of smoke. The other moved quickly with Qian Ying, luring the mosquitoes into the
