The walls of the tunnel were embedded with very rare red eternal fluorescent lamps. As a result, the floor was covered with a bloody light. The red light and the material of the walls were absolutely as same as that Zhang Tie saw in the piece of crystal.
After taking a look at the deep place of the tunnel with his lotus-flower eyes, Zhang Tie completely became reassured at once.
It was very easy for him to kill Old Man Taiyi. However, he was afraid of hurting Lan Yunxi. After taking a look at the deep place of the tunnel, Zhang Tie instantly recovered his composure.
After marching downwards for thousands of meters in the tunnel, Zhang Tie came to the door of a backroom.
The door of the backroom was opened quietly. Almost at the same time, Old Man Taiyi opened his eyes with amazement as he saw Zhang Tie walking in.
"Zhang Tie..." Old Man Taiyi exclaimed with an amazing look.
