He returns to his room.
Fang Hao prepares five beads of [Filthy Blood].
He takes out the Bone Bell and gives it a light shake.
The sound of the Bone Bell is not crisp and clear, it's more like a wooden mallet hitting a metal plate - a dull thud, and Fang Hao wonders if such a sound can attract the Cranial Rats.
Perhaps it would be more effective to shake it near a sewer.
Just as Fang Hao is contemplating whether to go out, a scratching sound is heard from outside the room.
Opening the door, he sees five Cranial Rats.
They are sitting straight up, their large eyes staring at Fang Hao.
When a single Cranial Rat exists, its intelligence is similar to an ordinary rat. But when five gather together and their brains resonate, they possess a certain level of intelligence.
Just that they cannot achieve the level of intelligence to speak and bargain with humans in the underground world.
