Song Jinqiao thought about it, nodded, and waved her hand. The river clam entered the space. Then she took out the dagger and looked at the crystal stones in the cave, and was silent for a moment.

"It seems like a bit too much, I can't finish it." She frowned.

But these crystals are very solid, and it is difficult for her to get them all out. She had to use a lot of effort to get the crystal out just now.

The system chuckled and turned into a creature that Song Jinqiao didn't recognize.

[Host, let Xiao Ling do it. The reason these crystals are so strong is because this wall has some strength. They can be easily removed by just using energy.]

Song Jinqiao suddenly realized and started to move the crystals by cooperating with the system.

Just as the system said, it was easy to take the crystal off, but Song Jinqiao had to use the dagger to pry it off bit by bit.

However, although the system was easy to obtain, the two of them still spent several days clearing out the crystals in this place.

"We need to see if there's another exit."

The previous exit had a lot of aquatic plants and was too dangerous.

[Host, look, what I found.]

After hearing what it said, Song Jinqiao looked over, but saw only darkness.

They had moved all the crystals and clams from this place, and the light disappeared. Song Jinqiao took out the sea crystal lantern for illumination.

"What's wrong? What did you find?" She swam over, shone the sea lantern towards the system, and found that there was still a hole here.

"How about we go out and take a look?" the system asked.

Song Jinqiao took out another sea crystal lantern and threw it in, then pricked up his ears and listened carefully.

There was no sound, but the sea lantern returned, rolling towards them.

[This cave should be facing upwards, so it rolled back.]

Song Jinqiao also agreed with it: "Let's go in and take a look."

As he spoke, he took out vines and tied them around himself and the system, letting the system pull him along.

"This doesn't seem to be natural, it looks like it's man-made." Song Jinqiao touched the wall.

The wall was cut very neatly, so it should be impossible to make such neat marks.

If this is really man-made, then orcs must have come to this place many years ago and carried out a lot of activities here. Of course, it was definitely not the Shaklinda tribe, because their murals record that they have been looking for this place.

Song Jinqiao didn't know where this dark cave led to. Nothing went wrong with her here, but there was something wrong with the system.

"Are you leaving now to upgrade?" she asked with a frown.

[Well, these crystals have too much power. I couldn’t help but inhale several times, and then…] Speaking of this, the system also felt very guilty.

It thought it would only take a few puffs and it wouldn't be a big deal, but it forgot the number of crystals and taking several puffs would burst it.

"Forget it, forget it. You go ahead and I'll take care of the rest." Song Jinqiao has become accustomed to this unreliable system.

Although the system was somewhat worried about the safety of its host here, the abundant power in its body forced it to leave.

The system left, and Song Jinqiao was left alone. She sighed, put the vines into the space, and swam upwards little by little with the sea lantern in her hand.

Fortunately, there was nothing dangerous in this cave, so Song Jinqiao swam safely. After swimming for an unknown amount of time, she saw the water surface and felt a little happy.
