The sky aircraft was extremely fast. Soon, it turned around and chased after the wave of red low-level mechanical beasts that was moving at high speed towards the Mars base of the Huaya Sector.
However, Yan Lie cautiously increased his flying altitude to more than 1,000 meters. High-tech equipment was quite reliable, but sometimes, it was also very fragile. The death of a person due to a crash was not a joke. Moreover, if the sky aircraft was destroyed, the 50 kilograms of Mechanical Spirit Alloy that was mortgaged would not be enough for Xu Tui and Yan Lie to compensate.
Xu Tui was a little relieved when he saw Yan Lie take the initiative to increase his altitude. Although Yan Lie's cultivation path was that of an assassin, he was not the kind of assassin who took risks for everything. It was more like the kind that planned before taking action and waiting for an opportunity to kill.
