Yang Fei nodded and, together with Nuannuan, stealthily approached the Demon Tower.
There were four sentries at the entrance of the Demon Tower, two visible and two hidden.
The entrance was fortified with defensive works, with a heavy machine gun facing the doorway.
Yang Fei and Nuannuan exchanged hand signals and then crawled stealthily towards the tower entrance.
Yang Fei pointed to the far left side of the Demon Tower, signaling that he would handle the two sentries on the left, leaving the right ones for Nuannuan.
Nuannuan nodded; dealing with these four sentries was not a problem for them.
The challenge lay in not making any sound; otherwise, it would alert the other armed defense teams, making rescuing the Old Witch Master silently quite troublesome.
Yang Fei extended three fingers, bending them one by one.
