Under the protection of the Thunder Guardian Bamboo, the two safely passed through the red lightning area and came to the green lightning area. On the way, the red lightning bolts that fell from the sky and bombarded Yun Yi would automatically bypass them when they were five meters above Yun Yi's head and shoot down five meters away from them.

In the green lightning area, the two of them came to a valley after climbing a hill, and after about ten minutes, they could see a deep pool in the distance.

When he came to the edge of the deep pool, Yunyi could clearly see this deep pool, which was very clear, but he couldn't see the bottom. At this moment, a gentle breeze blew across the water, causing it to ripple and spread.

"This deep pool is several kilometers deep, and there is a nest at the bottom of the pool, and there is a big monster in it, and its strength seems to be in the early stage of the Creation Realm."

Looking at the bottomless deep pool, Yuexi said with a serious face, and a trace of fear involuntarily appeared in her heart. Although Yunyi was by her side, she still felt that she was not very sure. If that monster is really the strength of the early stage of the Creation Realm, then the certainty is even smaller. But then it occurred to her that if she wanted to get the treasure, she should take some risks.

"In the early stage of the Creation Realm, why did you only say it now?"

Yun Yi's heart jumped and he was surprised, but he wasn't too scared. Thinking in my heart, this Yuexi told him at this time, the genetic realm of monsters, is it because I am worried that I am afraid?

"You're not scared, are you?"

Yuexi joked. The reason why he didn't say it in advance was because he was afraid that Yunyi would reject her directly, and there was no room for negotiation.

"How is that possible!"

Yun Yixian waved his muscles that were not strong, and said with a forced smile. The heart said, what kind of person can I Yunyi, how can I be afraid in front of the monsters in the early stage of the creation realm, I will save the men of the whole universe in the future! If Yuexi knew what he was thinking at this time, he would definitely laugh.

"That's the best, I don't know if this big monster is guarding some treasure."

Yuexi looked at the water and thought. If there was no treasure in the pool, it would be in vain, and that was not what she wanted.

Yun Yi looked at the water, and also said with some expectation: "Just go down and see." ”

Yuexi looked at Yunyi and said, "You're not afraid? What if that big monster really had the strength of the early stage of the Creation Realm. ”

Yun Yi thumped his chest and said, "Just kidding, since they are all here, how can there be any reason to retreat." Besides, you're not afraid, I'm a big man, what are you afraid of. ”

Yuexi showed a look of appreciation, nodded with satisfaction, and said, "Very good, I really didn't see the wrong person." ”

"It's an oxygen helmet, and you can breathe in the water when you put it on."

Yuexi took out two oxygen helmets and handed one of them to Yun Yi, and after she put it on herself, she plopped and jumped into the water first, swimming towards the depths of the deep pool. Seeing this, Yun Yi did not procrastinate, put on an oxygen helmet, entered the water, and followed.

An oxygen helmet can break down water into oxygen for a person to breathe. The decomposition efficiency is very high, there is no situation where oxygen cannot keep up, and the decomposition efficiency is automatically adjusted according to the user's breathing rate.

At this time, Yunyi and Yuexi gradually approached the bottom of the deep pool, 1000 meters, 2000 meters, 3000 meters, 4000 meters underwater......

By the time they reached 5,562 meters, the surroundings were not darkened by their depth, but rather brightened, thanks to a large school of glowing fish and aquatic weeds. The bodies of these fish and grass automatically glow like light bulbs, which is very strange.

It was inconvenient to talk in the water, so they turned on the interstellar communicator, turned up the light curtain, clicked into the notepad, and had a typing conversation. Although they are from different planets and speak different languages, they are both genetically modified and can read the universal script of the universe.

As for the universal language of the universe and the universal script of the universe, this information was packaged and stored in Yunyi's memory as early as when Yunyi underwent the first genetic transformation. The same is true for the moon.

Having said that, this interstellar communicator is of good quality but has nothing to say, and it has a good waterproof function.

Looking around, Yun Yi found that there was indeed a cave at the bottom of the pool, which must be the lair of the big monster. After the two of them communicated, they did not enter it immediately, but after searching around to no avail, they planned to enter the dangerous cave to explore the treasure.

When they came to the entrance of the cave, they stretched out their heads and looked into the cave, and found that it was also very bright, because there were also many aquatic plants growing in it, which illuminated the whole cave as if it were day. Therefore, Yunyi could clearly see that there was a big monster sleeping inside, and it seemed that he was sleeping soundly and comfortably.

The head of this big monster is like a snake's head, the neck is half the length of the body, and there are four strong flippers, according to the appearance of this big monster, it is obviously a spirit beast called the Thunder Eel Dragon, and it can release lightning from its mouth to attack the enemy, and it belongs to the members of the spirit beast clan.

It should have been captured by the Thunder Emperor and kept here as a pet, Yun Yi thought so. Then Yun Yi activated the energy bracer, and after some testing, he found that the strength of this monster was indeed in the early stage of the Creation Realm.

Looking at the huge Thunder Eel Dragon, both of them were a little scared, not because of the other party's size, but because of the other party's strength. If you want to search for treasures in its cave, it is tantamount to walking a tightrope in the air, and if you are not careful, your life will be guaranteed.

But now that it's all down, Yuexi doesn't want to give up now. As for Yunyi, he was not too afraid, because he had Xiaoling, a reliable bodyguard.

After observing for a while, Yun Yi saw that the Thunder Eel Dragon seemed to be really sleeping to death, so he mustered up his courage and swam in first.

Yuexi hesitated a little and followed, swimming behind Yunyi.

Yunyi looked back, and obviously felt that the other party was more afraid than himself, so he wanted to comfort the other party, so he turned up the light curtain, opened the notepad, and typed: "Don't be afraid, there is a brother, hold me tight, you're welcome." ”

"Die." After typing these two universal cosmic characters, Yuexi also entered a disdainful expression next to the words. Her complexion wanted to be red, but she couldn't get red, because the bottom of the pool was very cold, and it was good that her complexion didn't become pale. Although there is an oxygen helmet to protect the head, the cold of the body is transmitted to the head.

The cave is large and has many passages, which extend in all directions and crisscross it. The two of them cautiously swam past the Thunder Eel, slowing down, for fear of waking it.

When swimming past the Thunder Eel Dragon, Yuexi's heart was pounding, she thought that Yunyi's strength was about the same as her, so even if the two joined forces, plus if she used her hole cards, she would still be very embarrassed to deal with this big guy, and even her life would be in danger.

Yun Yi swam towards the passage on the left, and when he turned around, he saw that Yuexi was still following him, and he didn't dare to search for treasures separately, and said in his heart, he was so scared, but he still had to come down, I really don't know where you got the courage.
