Chương 2639: The Crystal City (3)

When he saw the crystal box, Zhao Hai's heart couldn't help but beat wildly. The box was almost the same size as the box that contained the Vermilion Bird seal.

Zhao Hai landed on the desk and looked at the box. His heart was beating wildly. Then, he reached out and lifted the lid of the box. Zhao Hai's breathing suddenly stopped. He took a few rapid breaths before he finally let out a long breath and slowly calmed down.

This was because Zhao Hai saw the thing that he wanted to see the most in the box. It was a large seal with a Xuanwu carving on it.

Zhao Hai let out a long breath, calmed his heartbeat, and recovered his spirit. He then slowly sent his spirit into the black Tortoise seal.
