Watching Tang Mei flashing inside ahead of him, of course, Zhang Tie, as a man, was unwilling to lag behind. He followed Tang Mei in closely through the gap of the gate.
There was a long tunnel higher than 100 m behind the gate. It was a bit dim inside the tunnel. There were evident damages and collapses inside it. In the well-preserved places, gloomy odd rune light was flowing over the ground. The entire tunnel was in dead silence just like a tunnel in an underground grave. They felt restless.
Watching those broken places in the tunnel, Zhang Tie took in a deep breath.
