The colonel gave a few words of advice to Lu Yu before turning around and taking the cable car back down the mountain.
As for Lu Yu, he was led by a soldier guarding the cable car terminal all the way to a cave halfway up the mountain.
After arriving at the cave entrance, Lu Yu was slightly astounded.
There wasn't any special reason. It was simply the fact that the strength of the force assigned to guard this cave had exceeded Lu Yu's imagination.
It was guarded by more than 20 cultivators at the Grand Master level. The place was even equipped with a weapon of mass destruction specifically designed to deal with S-class overlords of the Fearsome Beasts - the Magnetic Martyr Cannon!
With such a massive defensive force, this place was simply an impregnable fortress.
Yet, even so, that middle-aged general of Flame Country who was in charge of guarding this place still felt insecure.
