Wooden dog tags are the least effective.

If it's a black iron dog tag, it can be used three times, and all three Bloodhounds can exist simultaneously, which can play a huge role in small-scale battles.

The bronze dog tag can only be used three times, but it summons an elite Bloodhound.

It's even easier to use.

However, the spawn rate of this item is already very low; it might not appear even once in ten tries. Although it was a wooden dog tag, he was quite satisfied.

Put the dog tag directly into your belt.

Always ready for use.

Su Bai then walked through the alley. Ahead was a staircase surrounded by cold black iron railings on both sides. At the corner of the staircase, there were rows of cross-shaped coffins, each bound by chains. The shape of each coffin was very similar to the one that the corpse-collecting team had taken away earlier.

It's just that the color isn't that bright red.

In the center of this pile of coffins, there is an inconspicuous stone door that is almost integrated with the wall.

"arrive."

Seeing this, Su Bai thought to himself.

He took out Dr. Raven's protective suit and mask from his backpack, put them on one by one, and then took off the Raven badge and put it on the chest of the protective suit.

Then he stepped forward.

Knock lightly on the stone door.

Thump,

Thump,

Thump.

After three sounds, Su Bai stopped what he was doing and waited patiently.

About two or three minutes later, a heavy, dragging footstep sounded from behind the stone door. The person standing behind the door spoke through the door in an old, hoarse voice.

"Password."

Su Bai touched the badge on his chest, pondered for a moment, and calmly replied:

"Death is also a liberation."
