Chapitre 348: Mysterious Assassin (3)

"But the research on this substance has just begun. I'm not completely sure yet. I'll continue to study this liquid."

"Besides that, we found something interesting in its body."

As she spoke, Wei Wei walked back to the experiment table and grabbed an object from the metal tray. Then, she came to Feng Qi and opened her palm.

What appeared in front of Feng Qi was a small black ball. It was still stained with blue blood and was beating slowly like a heart.

"What is this?" Feng Qi was stunned.

"At first, I thought it was an organ, but after careful examination, I realized that it was not the case. It's like a tracking device."

As she spoke, Wei Wei came to the experiment table and took out a syringe. She stabbed the domain creature's arm and extracted some blue blood.

Then she dripped the blue liquid on the black ball.

Immediately, the small ball intensified its beating.

Seeing this, Feng Qi was stunned.
