The five-meter barrier was not an invisible wall as they had first imagined. On the contrary, it physically existed.
Just as the ruler in his mind reached five meters ahead, Ji Li reached out and touched a cold, glass wall.
The ghosts around them had all been lured far behind them, leaving a small empty area here, enough for them to investigate.
Ji Li tapped high and low with his palm and the tip of his foot, sketching out the glass wall in his mind.
After a few seconds of probing, he discovered that it was a decorative wall.
Before this, he had only seen the skybridge connecting the three buildings from outside the stairwell. From the outside, it looked like a long glass walkway.

Of course, these walls had also divided nearly a hundred ghosts into four sections, preventing a twenty-meter corridor packed with ghosts.
