The mysterious voice only answered him with this one sentence, and no matter how he asked, it would not speak again.

At this time, Coco had already crawled into Xu Xin's arms, buried her head and shivered.

There were so many monsters below that even at a depth of a thousand meters, Xu Xin could still feel the oppression of those huge monsters, not to mention Coco.

Fortunately, the mysterious voice just said that they don’t need to deal with these huge monsters now, and they have to consider how to resolve the beast riot first. In other words, these monsters will not come out now, and he just knows the content of the later versions in advance.

This really made Xu Xin feel relieved.

He suddenly thought of something.

"Coco, didn't you say the treasure chest was right here? Don't tell me it's down there, right?"

Let's find the golden treasure chest first. Xu Xin relaxed his current mood and rubbed the little guy's head in his arms.

"嘤!" Coco suddenly remembered this incident, jumped out of Xu Xin's arms, tugged at Xu Xin's trouser legs, and motioned Xu Xin to follow it.

Outside the huge round iron gate was not just a small hole on the cliff, there were other openings on the cave wall, but Xu Xin was completely shocked and did not notice it.

Following Coco, Xu Xin soon reached the end and saw the golden treasure chest at the end.

Even in the dark underground world, this treasure chest still emits a faint golden light, illuminating the surroundings at the end of the cave.

Xu Xin examined the treasure chest. He first confirmed the pattern on it. It was indeed a beast's head, but it was different from his image of a Qilin. It seemed the three treasure chests didn't have Qilin printed on them.

Xu Xin decided to open the golden treasure chest here.

He took out the key, inserted it into the keyhole of the golden treasure chest and twisted it. A mechanical sound was heard and the treasure chest was opened.

"Ying!" Coco climbed to the edge of the golden treasure chest and looked inside.

Inside the golden treasure chest was a bottle of gray potion and a thin card.
