The fog is getting thicker and thicker.

Chen Feng held the engineering shovel and moved towards the west side step by step against the outer walls of the buildings along the street.

The road ahead was in a state of disarray, with gravel and weeds intertwined together.

Chen Feng had to be careful every step he took, for fear of making too much noise.

After walking about sixty or seventy meters, a vague outline gradually emerged from the thick fog ahead. It was a two-story building.

The entire small building is a bit shorter than the surrounding residential buildings. Large areas of white paint on the exterior walls have peeled off, revealing the dusty cement underneath.

Chen Feng slowed down and looked forward through his goggles with squinted eyes.

I saw a horizontal plaque hanging above the door of the small building. The plaque was crooked and only one end was still hanging on the nail. The other end was hanging down and swaying gently in the breeze.

The words on the plaque were eroded by wind and rain, and there were no strokes or strokes, but a few words could still be vaguely discerned.

【Liu's Martial Arts School】

Chen Feng's heartbeat accelerated slightly.

Found it, the martial arts gym mentioned by the middle school student in the diary is here.

He took a few steps forward, and as the distance approached, the outline of the small building became clearer.

The two-story-high door of the entire small building was ajar. Most of the wood on the door panel had rotted, and darkness shone through the crack in the door.

Afterwards, Chen Feng stopped seven or eight meters outside the building.

After looking at it for a few seconds, I didn't rush in.

The world of Daxu is so dangerous, with alien creatures everywhere. Who knows if there are other monsters in this small building?

Chen Feng thought about it for a while.

He bent down and picked up a fist-sized piece of gravel from the ground, and threw it into the door of the martial arts hall.

Bang!

The gravel drew an arc in mid-air, then landed on the ground in the martial arts hall, bounced twice, and then rolled far away, making a series of noises.

Chen Feng pricked up his ears and listened carefully for a while.

One second, two seconds, three seconds... there seemed to be no movement.

He picked up another bigger stone, and this time he didn't throw it into the door, but hit it on the outer wall of the martial arts hall.

Bang!

The stone hit the cement wall and exploded with debris flying everywhere, making a loud noise.

However, after waiting for a while, there still seemed to be no movement of the alien creature inside.

Chen Feng felt a little relieved, but he was still a little worried.

So I touched another piece of gravel on the ground, and this time I used 70% of my strength to throw it directly into the doorway.

The stone flew in and drew an arc in the darkness.

Snap!

There was a sudden silence in the martial arts hall.

Two seconds passed.
