This time, the three-fold explosion rate of [Prospector Steel Pick] had an effect. In an instant, fifteen copper ores appeared. Xu Xin could only try his best to collect them, but in the end, three of them fell.

Shaking his head, he swam in front of a piece of blue ore.

The blue light only accounts for a small part, and only a piece of blue-grade ore should be excavated.

Xu Xin waved the steel pickaxe.

After more than a dozen excavations, he finally obtained the first piece of blue-grade copper ore.

And the second and third pieces.

The triple explosion rate triggered again! And this time it happened to be triggered on blue-grade ore!

Really good!

After putting the blue-grade copper ore into his backpack, Xu Xin stuffed a water plant into his mouth and continued to dig it for a while.

"Click!" "Click!" "Click!"

Soon, hundreds of pieces of copper ore were already in his backpack.

Among them, there are eight blue-grade copper ore.

After that, he mined three blue-grade copper ore, and another triple explosion rate.

"This prospector steel pick is really good!" Xu Xin was very satisfied with the effect. Not only blue-grade copper ore, but also green-grade copper ore has exploded, saving him a lot of time.

There are still many green ores that have not been excavated on the cave wall. Because this big hole is very large, on the 40-meter-deep cave wall, there are all such ores in a whole circle.

But Xu Xin has decided to go up.

He has been digging for almost an hour, and according to his request, Lou Feier should have been back.

Moreover, the water temperature was too low, and even though he had been moving, he could no longer bear it.

The most important point was that he obviously noticed something was wrong around him!

The water flow around this area, which was originally rotating slowly, is now much faster than before!

Now if he doesn't hold the hole wall with his hands, he will be directly taken away by the current of water!

Moreover, what made him feel a little creepy was that he seemed to hear some kind of low sound coming from the depths of the hole, like... the roar of a whale.

The sound was looming, but it was still captured by his hearing amplification.

There is something deep in the water!

It’s better to go up now!

There are now more than 500 green-grade copper ores and eight blue-grade copper ores in his backpack. According to the rules, five metal ores can melt a piece of metal. If they are handed to Li Wenxi for her to melt, the final metal block will be more.

It should be able to meet the needs.

Go up!

Xu Xin began to float slowly.

The water flow in the cave was really much bigger, and he was spinning along the wall of the cave.

In the bottomless hole, a low voice kept coming upwards, making Xu Xin's heart hang, her teeth clenched, and she looked down from time to time.

Could it be the giant anaconda in the middle of the lake?

Don't just pull it out?

No, the anaconda should not have a sounding organ?

However, the snail could not survive in deep water, and the original laws of the world could not explain anything here. In his opinion, this giant snail is almost the same as a dragon.

In the end, Xu Xin poked his head out of the water without any danger, breathed a long sigh, and swam quickly towards the nearest lake.

Because as the water flow rotates, his position is far from where he went into the water.

Xu Xin swam to the shallow water area, swims ashore, and walks around the lake towards his original location, where Coco is still waiting.

From a distance, he heard Coco's anxious screams.

"Yeah! Yeah!" Coco ran back and forth by the lake, shouting at the lake.

Finally, it jumped into the lake itself, and its little claws swam towards the center of the lake.

"Koke, I've come up!" Xu Xin quickly ran towards Koke.

"Yeah?" Ke Ke floated on the lake and looked back at Xu Xin, "Yeah!"

Xu Xin quickly fished Cocoa from the lake. This little guy could float on the water, but the swimming speed was really not satisfactory.

"Hehe! Hehe!" Keke rubbed his wet head into Xu Xin's arms, then pointed at the lake water and screamed twice, then shook his body, and the water on his body shook Xu Xin's face.

Xu Xin doesn't care. He has just come out of the water anyway, and he is already covered in water.

"There is danger in the lake..." He understood what Coco meant, looked at the bottomless center of the lake, and swallowed.

It seems that the faint and quiet voice just now was not his illusion.

And the faster and faster water speed...

Xu Xin was a little scared. It was really a terrifying danger. Otherwise, Coco would not be so anxious. He jumped directly into the lake and wanted to find him.

The exploration of this lake should be put on hold for the time being.

The ore in his hand is enough for the time being.

Let professionals do professional things. After connecting with Qin Yunlong and others, let them come over and explore in the water.
