章 141: Attraction

Rows of game notifications refreshed, and Fang Heng noticed that some of the materials in the shelter had disappeared.

The underground shelter expanded again.

After the renovation, Fang Heng had gained twice as much extra space as before!

"It's enough for now!"

Fang Heng checked the two new functions of the shelter after the upgrade.

One was the recruitment of NPCs.

Now, the shelter could attract survivors up to C-level.

It was not bad. After all, survivors below C-level had almost no special skills.

Only C rank survivors had the potential to become lab workers.

The other was the increase in the shelter's defense value.

Unlike ordinary buildings, after players built a shelter, it would be considered an entire building. Any attack on it would reduce its overall durability.
