After walking through the zigzag underground passage for ten days, there was still no end in sight, this distance was almost comparable to the distance from the novice village of the elves to the underground world, who would build such a long passage underground?

Although many parts of this channel are corroded by the flow of groundwater, there are many places that have been dug by hand, and the amount of work is simply too large.

Now the passage is along a small underground stream, but it is the king who walks upstream, and there is no choice but to go upstream, because the downstream disappears directly into the rock crevice.

The most amazing thing is that this groundwater is not fresh water, but salty water with extremely high salt content, and the smell of the sea is quite strong, so the upstream source is very likely to lead to the bottom of the sea, and what the situation is can only be found at the end.

To be honest, the three of them are quite depressed, if they knew that this passage was so long, they would not have come over in the first place, but now they have been walking for more than ten days, of course, it is impossible to give up halfway, so they can only continue to move forward.

Since there are no monsters in the passage, this journey has completely become a wandering, and the ten or so days of travel time have taught the two elf girls a lot of formation knowledge, and at the same time taught them many postures...... Well, it's just a refining posture, not a snapping posture.

Although it can't practice qi, but refining the body directly meridian acupuncture points, activating the potential of the body, and enhancing attributes, it still has quite a good effect, to be honest, the two elf girls are very fascinated by this body refining exercise.

After Li Yunfei taught them, they would practice a set of exercises every time they had a break, and even unexpectedly discovered that refining body movements could also allow the body to absorb more natural power, so the two quickly left Li Yunfei, the teacher, far behind.

First of all, Amy's physical training effect is better, in just ten days, she has completely mastered a full set of movements, exercising for an hour a day, and the improvement of physical fitness is even comparable to one-fifth of the time when she cleared the monster in the underground world, which does not look high, but it is actually amazingly high.

Amy's speed made even Linnie a little jealous, so she became much more diligent in exercising in the past two days......

"The talent of your elven clan is really enviable, jealous and hateful." Looking at Linni, who was forcibly exercising, it would not damage her body, Li Yunfei was really envious, Li Yunfei didn't dare to practice more, there would definitely be side effects for more than an hour a day, but the elf clan could avoid those side effects, which really made Li Yunfei envious.

"You can't say that, the learning and creative talent of the human race can't catch up with our elven race!" Linnie responded

"It's a world of strength."

"The strength of the human race is also the strongest among the seven races of the alliance."

"Uh, okay!"

“…… Captain, can you do me a favor, my leg is numb! "I was about to finish my body training, and suddenly I found that my legs were completely numb.

"Willing to help!" A flash appeared next to Linnie and she was very skillful in pushing Linnie up, but Amy, who was exploring the way in the distance, was very excited and ran back.

"So happy, but a big discovery?"

"Yes, yes, it's the end of the day!" Amy said excitedly.

"Thank goodness it's finally coming to an end, but where is it outside?"

"The sea, the end of this passage is really the sea, let's go quickly, less than two kilometers away."

"Don't worry, sit down and rest, and wait for Linny's leg to recover before walking."

"Oh...... The captain is so good to Lynny! ”

"Why, am I not good to you!"

"Yes, yes!" Amy's face turned red when she didn't come, but she remembered that she secretly asked the captain for formation knowledge last night, but she went to bed not long after asking for advice, and unexpectedly found a lot of very magical postures...... I can only sigh that the human race really knows how to play.

……

The three of them soon reached the end of the passage, but an enchantment blocked the way, and on the other side of the enchantment was really the sea, or the bottom of the sea. I just don't know whether this is the Endless Sea or the Extreme North Sea, or some other unknown mysterious sea, and after walking in the winding underground passage for more than ten days, I don't know what realm I have reached now.

Although the other side of the barrier is the bottom of the sea, it is also quite bright, the sea in this world is completely different from the real world, many aquatic plants can emit all kinds of strange fluorescence, and many fish can also emit self-light, all kinds of light under the reflection of water waves, look at the colorful look extremely beautiful.

This barrier was obviously built by the alliance members, so it would not prohibit the alliance members from passing through, but the three of them were a little hesitant to stand in front of the alliance and did not dare to take risks easily.

The strength of the monsters in the two known sea areas is very strong, judging from the data, the strongest monsters in the Endless Sea are equivalent to the strength of the late congenital stage, and the strongest monsters in the sea area of the Extreme North Sea have reached the strength of the early stage of Jindan, these monsters are really not something that the three of them can solve at this stage.

Now Li Yunfei's strength is only able to run away if he faces the late congenital stage, and if he faces the strength of the Jindan period, he will probably not even be able to run, and there is no way to summon a powerful jade seal magic weapon to kill monsters at a higher level in this world......

Although the situation on the other side of the barrier can be seen clearly, it is impossible to use the divine perception to detect the degree of danger, and although the barrier does not block the view, it blocks the divine perception of the divine mind.

"You guys wait here, I'll go over and see the situation first, and if the situation is not right, I will return immediately!" Li Yunfei finally decided to go over to see it, believing that with his own strength, as long as he didn't encounter a super boss as soon as he passed, he would have the power to protect himself.

“…… Captain, we are a team, if there is danger, it is better to face it together, otherwise the captain will always take care of us, then we will never have a day of real growth. Linny took Li Yunfei's hand and said seriously.

"That's it, since we're a team, let's act together, it's not good to always take risks alone." Amy also took Li Yunfei's hand and said.

“…… Okay, all open the bracelet on the force field guard, in the past, let's not disperse, if the situation is not right, immediately retreat. ”

Seeing their serious looks, Li Yunfei finally agreed to their request, in fact, what they said was right, they always took care of them, which would only affect their growth.

The three of them activated the force field shield on the bracelet together, and the three shields fused together to form a joint shield with stronger defensive capabilities.

The pressure of the sea water is not as strong as expected, and according to the information feedback of the force field shield, the water is less than 100 meters...... As soon as the three of them appeared at the bottom of the sea, they immediately attracted some fish around them to swim over, but they didn't attack, they turned out to be very normal sea creatures, and what surprised Li Yunfei the most was that this place was not invaded by chaotic energy......

"Wow, it's so strong and natural, it turns out that there is such a good place in the world!" Linnie and Amy exclaimed, the two of them directly removed the force field shield and swam happily, as for the water pressure of more than 100 meters, it was nothing for their powerful physique.

"Let's go to the surface first!" Li Yunfei grabbed the elf girl and rushed directly towards the water.

However, after surfacing the water, the three of them were stunned, and there was an island floating above the water not far away, which emitted colorful light......

"Terrans, elves, why are you here?" Suddenly, a rather old voice remembered in the sea of meanings of the three people, but there was no figure in sight.

“…… The juniors and others inadvertently broke into this place, can the seniors show up? Li Yunfei responded very politely.

"I'd like to show up, but I'm afraid I'll scare you little ones!" The old voice sounded again.

"The juniors and others are not so timid, although the seniors show up!" Li Yunfei said very calmly.

“…… In that case, let's meet it, I really haven't seen a Terran in years. The old voice hesitated for a moment, but finally agreed, and as soon as the words fell, the rainbow island floating on the sea in the distance suddenly moved, like a giant beast that had been sleeping for many years woke up. The colorful glow on the island then dissipated, and clusters of flames began to rise from the island, and in the blink of an eye, the flames filled the entire sky.

The momentum was huge, and it could only be described as shocking, but in a blink of an eye, the sea water began to boil, and the three of them also opened the stand shield for the first time to isolate the layers of heat waves radiated by the flames, and the two girls were obviously a little frightened, and grabbed Li Yunfei's hand tightly.
