After thinking for a while, Mu Rufeng took out his phone and searched; most helicopters can only fly up to an altitude of six thousand meters.
However, there is a type of armed helicopter that can fly up to an altitude of twelve thousand meters.
The Mi-24 armed helicopter was manufactured by a certain Soviet in the last century.
In 2014, it seems that domestic armed helicopters could not fly up to ten thousand meters.
Fighter jets certainly can, but Mu Rufeng has never piloted a fighter jet, not even an armed helicopter.
It's currently a little past five, with less than seven hours left until the Rule Clock descends at noon.
"Time is quite sufficient, it seems I can only go find Wang Luo and ask him to help solve the helicopter issue." Mu Rufeng thought, stroking his chin.
Mu Rufeng is now certain that the Rule Time Space is not formed by the rules of this world, nor the rules of half of another world.
It is definitely created by a third-party force.
