บท 457: Chapter 457: No Return on Arrival? Counter Scheme? (Big 6000-chapter for monthly tickets)

```

Faint soul threads stretched out in midair, leading straight down beneath the floor.

He Ao immediately left the hospital ward and burst into the corridor, descending the stairs to the same position on the floor below.

Indeed, in this ward, there were long ethereal threads of soul that fell from the ceiling and disappeared into the floor.

He Ao continued to the next level down.

The soul threads on this floor no longer spread downwards but drifted into the corridor instead.

Following the direction of the soul threads, He Ao found an old fire hydrant box at the corner of the curved corridor.

It was into this fire hydrant box that the drifting soul disappeared.

He Ao opened the fire hydrant box, which appeared to contain normal firefighting hoses.

The threads of the soul disappeared into the wall behind the fire hydrant box.

He Ao closed the fire hydrant box and turned to enter the ward behind it, but there were no soul threads spreading out in this room.
