Because a large number of oxygen cylinders had to be filled into the blisters blown out by Crab Commander, the time for Mu to swim into the sea was chosen in the middle of the night. A whole car of oxygen cylinders quickly moved to the beach under Mu You's strange power, Commander Crab poked his head out and blew a bubble to put it all into it, and then blew out another bubble to wrap his master in, accompanied Xiaolong to pull the two bubbles, and officially set off under Mu You's order!

Advancing on the deep seabed, you are not afraid of encountering any cruisers, nor do you have to worry about being caught smuggling across the border. After arriving on the high sea, in order to save oxygen consumption, Mu You asked Commander Crab to lift himself out of the sea, sit on Commander Crab's back, and float on the sea surface in the direction of the Phoenix Jade Pendant's ray.

If you don't go out to sea as a whale, it's not bad to sit on the Commander Crab of the Demon Beast, and the size of the Crab Commander is about six meters away, which really feels like a luxury yacht.

It was already autumn, and the sea water splashing on the bare shoulders was blown by the sea breeze, and it was somewhat cool. The sky on the sea is much brighter, and the moon on the sea is a little clearer. It is said that this autumn is sad, but for Mu You, it is a bird's egg, thinking of all kinds that may appear in the direction pointed by the phoenix jade pendant, it is called the excitement and anticipation on the face.

Because of Mu You's relationship, the speed of Commander Crab and Xiaolong was much slower, starting from eleven o'clock in the evening, and at 3 o'clock the next day, they passed by the 4.3838 square kilometers with special significance. If you let Xiaolong and Commander Crab scatter their speed, these four hours are enough for several round-trips. He took a deep look at the small island that made several countries happy and worried, and then headed south, passing through the Yaeyama Islands at around 4 o'clock, and let Commander Crab stop not far from the edge of Yonaguni Island.

Yonaguni Island is located at the westernmost point of the Yaeyama Islands in the Ryukyu Islands and is the westernmost island under the jurisdiction of the island's great aunt. It is located off the coast of the northeast of Taiwan Island, only 111 kilometers away from Taiwan Island. Originally part of the Ryukyu Kingdom, it was illegally occupied by island nations along with the Ryukyu Kingdom.

Mu You let Commander Crab stay here according to the GPS global positioning system, not to get a peek at the island country here, of course, if there is a warship with the flag of the island country's aunt or something, Mu You is very interested in giving them a little excitement. Mu You's main purpose here is because there is an underwater ruin around Yonaguni Island.

Mu You has been in the bottom water city of Qiandao Lake since the bottom of the lake, coupled with the appearance of the phoenix jade pendant, and now he has a demonic interest in the underwater ruins, and he has already scolded the world's underwater ruins and even the legends of some undersea ruins before going to the sea.

Yonaguni Island's underwater ruins include the remains of the last ice age, the remains of terrestrial flora and fauna, and the remains of stalactites. These imply that the remains of the seabed may be more than 3,000 to 10,000 years old, probably the oldest in the world.

With such a long-term existence, Mu You naturally wants to explore it, and he doesn't want anything else, as long as he can find some good things that are at the same level as the Body Refining Pill, it will be worth the trip.

At the same time, it is also for deep-sea exploration to do an experiment and gain experience or something.

After letting Xiaolong go down and go around for a while, make sure there is no problem. Mu You ate some high-energy food brought by the storage jade slip to solve the physical fitness problem, and then took a few deep breaths, and after lifting his spirits, he got into the blister made by Commander Crab and began to dive.

After diving less than a thousand meters, Mu You, who put on night vision goggles, saw the remains of ancient buildings underwater.

It is a ruins of an ancient city that resembles an altar, with square structures covered in coral, large angular platforms, and buildings such as streets, staircases, and arches, covering an area of nearly a kilometer.

Mu You fell into the ruins of this ancient city, and immediately launched the Sky Eye System to check if there were any energy fluctuations. Today's Sky Eye system has a coverage range of more than 40 meters, and it is easy to search the entire ancient city ruins. The only problem is that it is a little unaffordable, and it can't be left on all the time, on the premise of not leaving any corner, there is no problem with Mu You's intermittent surname.

Mu You successively saw various stone buildings, pillar pits, human head statues, arches, stone tools and turtle sculptures with geometric figures. The appearance of the human head statue is slightly ancient, slightly different from that of modern people, with slightly convex cheekbones, pointed ears, and closed eyes. Other than that, I can't see anything else.

What surprised Mu You the most was that he saw some ancient hunting pictures after opening the entwined coral on a wall, and on the largest of them, Mu You saw the text, which was exactly the same as the text font on the phoenix jade pendant and the mysterious gold coin!

What exactly is this text and why does it appear here?

Mu You couldn't understand the reason for this, and he didn't understand the meaning of these words, so he took out his camera and took pictures of them all, keeping them for later use.

In the center of the altar-like building, there is a huge stone carving of a strange colorful sacred cow, carved out of the cow's head line, focus, presentation and side with a horn pattern and a few lines of words, the format is almost exactly the same as the phoenix jade pendant, but unfortunately there is no ability to fluctuate, can not be identified.

Mu You guessed that the strange cow on this stone carving was very likely to be a totem like the phoenix of the phoenix jade pendant, but this stone carving was not made of the essence and blood of the cow, and it may have been copied from it.

After walking around for a whole time, there were no windfalls, but more and more questions.

Everything has a two-sided surname, and if there are more questions, why not more clues! Mu You comforted himself.

It is good to look at the problem with the right dialectical approach at the right time. The reason why dialecticism is so unfathomable is precisely because its simulations are well-founded, and at least it can comfort itself at the right time. If you're in a good mood, everything will be fine.

When Mu You was thinking about himself, the little dragon who was wandering and patrolling outside came with a strong message, as if he had discovered something.

Mu You, who stayed in the middle of the blister, was pushed by Commander Crab and soon appeared on Xiaolong's side. The location of the little dragon is ten miles away from the underwater ruins, in front of him is a row of submarine mountains, the little dragon is circling around a towering stone, the stone from the bottom to the top from large to small, to the top is already very sharp.

Mu You took a look at the Tianyan system and was overjoyed, he finally found something with energy fluctuations!

Let Xiaolong and Commander Crab carefully smash the periphery of the stone, the reason why they did this was because Mu You had already used the Tianyan system to see what was inside.

When the stone skin on the outside peels off, what is revealed is a building.

Pyramid!

A small pyramid!

It's about three stories high, all of which are made of stone mosaics, and no one has noticed it for so long because of a mask covering its outside.

The energy fluctuations come from within, from the inside of the pyramid.
