Chapter 374: The Five Blood Kings Strike!

"What's wrong?"

At this moment,

Zhao Tengqi saw Qin Chen's astonished expression upon seeing the image of the key, which left him somewhat puzzled.

Upon hearing Zhao Tengqi's question, Qin Chen did not respond.

Instead, he just thought for a moment and took out a pure gold box from the God Devouring Crystal.

This box was what Qin Chen had obtained from Yiu Hai's Qiankun Bag after he had killed him.

In front of Zhao Tengqi and the others, Qin Chen opened the box.

Instantly,

a key, identical to the one in the image, appeared in front of them.

"Is this... the key to the Sea Sky Treasure Vault?"

Upon seeing this key,

Zhao Tengqi and Lin Songyun were both slightly agape, their eyes filled with astonishment.

Obviously,

they had never dreamed

that Qin Chen would have the key to the Sea Sky Treasure Vault in his possession.

"So this key really is the key to the Sea Sky Treasure Vault..." Qin Chen muttered to himself.
