This half-elf not only has a system

Brobro and Lailai dived into the water just after Anzi arranged their tasks.

Brobro uses the Argonian swimming style. It can also be said that it is a way of swimming, not something humans can do. He has thick scales, like a blue dragon swimming in the water. Same.

It's just a miniature version of Canglong, Lailai is very relaxed. It has no body parts that can make it swim, but it can move freely in the water, which is very impressive. Maybe this is a small difference between monsters and creatures. The gap or difference.

"Brobro, can you speak in the water?" Lailai asked.

The two people were almost ten meters away.

"I can make sounds, but I can't speak. No matter what, I still breathe with my lungs." Brobro said.

The vocal structure of the Argonians is similar to that of humans, but there is a valve in front of the vocal cords. The valve can isolate the water. The vibration of the vocal cords alone can make sounds in the water, although the distance is not very far.

"I sense some signs of life down there, do you want to investigate?" Lailai asked.

Brobro nodded.

Argonians do not have external ears. Their perception of sound comes from the cavity in their brains, and they do not have eardrums, so they do not need to decompress in the water.

They also have underwater breathing skills, but instead of being able to breathe underwater, they store gas in the cavities of the body. At the same time, they can increase the time they can move underwater and circulate in the body.

The Argonians lived near swamps in the early days. They basically relied on their smooth scales to move in the swamps and fished in the surrounding lakes. They might not be able to enter the deep sea, but they had an absolute advantage in inland lakes.

Lai Lai took the lead and swam downward, but in Bro Bro's eyes Lai Lai seemed more like sinking.

"Brobro, have you seen that cave?" Lailai asked.

"There is actually a cave down here?" Brobro stopped.

"Yes, there is still life in that cave," Lailai said.

"Should we go back and inform the boss?" Brobro asked.

"I don't think it's necessary. You and I can handle the things inside, and..." Lailai turned around and smiled. Although he couldn't see its face clearly, he could still see a cute expression.

"And what?" Brobro asked in surprise.

"Don't you want to make a contribution? If you clean up all the guys in this cave, your level should also increase."

Brobro thought for a moment, then swam down.

"Don't stand there, let's fight quickly!"

Lailai followed Brobro and helped him observe the surroundings.

This is an underwater cave. After entering the cave, although it was darker than outside, both Brobro and Lailai were able to find the direction, and then they started to swim upstream.

This cave is not like a cave formed by the principle of a connector, but made by someone pouring air into it.

"The air here is still very fresh, and there is still some moisture inside." Brobro said after getting out of the water.

"That is to say, this place was formed just now." Lai Lai said.

"No matter what, let's go inside first, Lailai. If an enemy appears, you must tell me!" Brobro took out his spear and said.

"no problem."

The cave is indeed naturally formed, but the water has been drained out recently. You can see some small puddles inside, and these small fish inside.

"One thing I'm sure of is that they need to live in the air because they expel the water," Brobro said.

"One more thing, they can also survive in water, otherwise it would be difficult to compress so much air into such a large cave." Lailai said.

Through the deep stone passage, the sound of dripping water kept appearing, and it became darker and darker inside.

Both Brobro and Lailai were sweating because it was too dark to avoid being attacked by the enemy.

They were walking and suddenly stopped.

"Brobro, let's not go in yet. It's too dark and I can hardly see." Lailai said.

"What should we do?" Brobro asked.

"In this case, you stand behind me." After Lai Lai said, Bro Bro did so and stood behind Lai Lai.

Then Lailai was quickly inflated like a balloon and got stuck in the middle of the stone path.

"What are you doing?" Brobro asked.

"Force the things in here to come out. You have to pay attention. If something comes out, you must respond in time." Lailai said.

Brobro assumed a fighting stance, waiting for Lailai to attack.

Then he watched Lailai's body begin to harden. The reason why he looked hard was because the bouncing body felt like it was frozen, from the bottom to the top.

"I understand, you want to release the air conditioning inside, right?" Brobro said.

"The zero-degree breath can spread in any space, and the effect is best in a sealed space, so I blocked this place and only let the cold air enter there. No matter what race you are, you will be afraid of the cold air!" Lailai said.

Time passed by, and Lai Lai turned into a large transparent ice block. Through Lai Lai's body, you can see that there are ice slag on the wall and everything on the other side. As long as it can freeze, it is frozen. The other side is like a freezer.

"Why don't you come out?" Brobro asked.

"It seems these guys are quite tenacious!" Lailai said.

Then a huge wind sound was heard coming from Lailai's body.

This is Lailai increasing the intensity of the air conditioner.

But there was no movement inside.

"Is there nothing inside?" Brobro asked angrily.

"Impossible, I have detected it, they are still in place...wait a minute, they are already coming towards us." After Lailai said this, he immediately stopped releasing the air conditioner.

Start thawing yourself.

"Why did you stop?" Brobro asked.

"My estimate was wrong. I have been blown by the cold air for a long time without making a sound, and now it is moving quickly towards me, and there are more than one of them. I will carry it here, and you go find Mr. Anzi! Hurry up!" Lailai said excitedly.

Its body was still a big lump of ice, motionless. Although it used air-conditioning to attack and froze itself, it did not receive any damage.

After Lailai described it like this, Brobro immediately turned around and prepared to leave.

"I'll leave this to you! You must hold on until the boss comes over!" Brobro said.

"No, I was wrong again. Tell the boss to leave here quickly. There are many of them, and they may be stronger than me. Evacuate this place quickly!" Lailai shouted.

Broblo was stunned for a moment, but immediately nodded and prepared to run back.

----------

"Did you encounter something? Do you want me to run away?"

I've been watching them from behind since Lailai started to thaw.

Moreover, Goss guessed correctly. They were indeed ghosts. There were quite a lot of them, and most of them were physically immune. In this case, I could only act as a living doctor.
