"As long as it is solid, it can reflect ultrasonic waves. If it is a city made of crystal, dolphins can also find it. Cities are used to resist invasion. Naturally, they must be strong, easy to defend and difficult to attack. Even the Sea Spirit Tribe has its own characteristics in the water.

Powerful natural enemies. You must know that tens of thousands of years ago, monsters emerged in endlessly. If the Sea Spirit Tribe wants to protect itself, it naturally needs a powerful urban machine as a guarantee."

Liang Shuang explained to Xiaoling as fast as he could.

"Children are so kind."

Even Sophia was a little teasing. In their eyes, Xiaoling was just a little girl with some innocent thoughts, which was normal.

"The Crystal Palace seems to only exist in mythology. Even the Crystal Palace in mythology seems to be made of stone."

Qiu Ke patted Xiaoling's shoulder and shrugged. The Crystal Palace's statement does not exist in the world of adults' rationality.

"What if what Xiaoling said is true? The Crystal Palace has appeared in many legends. The famous "Pistil Woman" in "Journey to the West" and "Yi Jian Zhi" all have descriptions of the Crystal Palace in "Collected Poems". If according to ancient times,

With the level of technology, it is not impossible to build a palace with crystals, and it seems to be more in line with the aesthetics of the Sea Spirit Tribe."

The one who spoke was Lin Hun. He was climbing onto the boat and took off his wet cold-weather clothes. Even he could not bear the hardship of exploring deep water for a long time. The fallen mermaids were also exhausted. There were creatures in the deep water.

The idea of ​​a restricted area is not a lie.

"Hun Lin, come back. How's the situation?"

Lin Hun's return made these women who had no backbone become excited again. In their eyes, every decision Lin Hun made was correct and convincing enough to convince everyone.

"The situation is not good. The Zhepeng people's defenses are too wide, and most of them are within 300 meters underwater. The ten submarines discovered so far are all exploring around a hill, and they seem to have found some clues."

Lin Huan pointed at the circle Sophia drew around the hill and placed icons of ten submarines. Looking at the great plain drawn by Liang Shuang, he hesitated for a moment and also drew a large

Submarine icon.

"Where are they drilling in the plains? Are they not afraid of destroying the city?"

From the submarine Lin Huan drew, Sophia could see that this submarine was enough to carry a large drill, and it was not impossible to even carry a nuclear bomb.

Rumor has it that traces of undersea cities have been found in Zepeng, South America, and the Bermuda Triangle. However, these undersea cities are all above the ground and in the sea water. The buildings are well-proportioned, and large-scale ultrasonic detection can almost all map them.

3D city silhouette.

If Daxizhou was built under the plains and covered with earth crust or steel, then the Sea Spirit tribe would not live in the sea, but underground.

Since the submarine was placed on the plain, it means that the Zhepeng people must have made a discovery.

"Daxizhou is built on the bottom of the sea, which is not in line with the living habits of the sea people at all. Although we live in the sea, we also need light, full of sunshine, moonlight and warm waters to meet the pursuit of our sea people."

At some point, Helen jumped on the Princess Neer. As a member of the sea tribe, she had the most say.

"Sunlight and moonlight are the two major sources of energy for the Sea Spirit Tribe. There is really no reason to build a city under the sea."

With the explanation from an authoritative person, Sophia had to readjust her thoughts. Her eyes were fixed on the projection again.

"Submarine? Energy. Oops, submarines are also located through ultrasound. The ultrasound of the dolphins just now did not show that there is a submarine at this location. Have they discovered the dolphins?"

Xianya, who had been dozing for days, suddenly shouted. The analysis just now almost exhausted her energy. But she still had a strong sense of war, and she quickly discovered the potential danger.

“Can a submarine capture dolphin sound waves?”

Yin Tou, who had been silent all this time, suddenly raised his head, a trace of panic flashing in his eyes.

"Such a strong ultrasonic detection can alarm a submarine. As long as you deliberately capture it, you can definitely detect the abnormal movements of dolphins."

Qiu Ke had the best relationship with Yin Tou, so he rushed to answer directly.

"So Angel and Luffy are in danger?"

Xian Ya suddenly woke up and frowned, as if she felt something.

"Look at the screen? There are submarines approaching dolphins, and there are boats!"

Xiaoling's reminder made everyone focus on the screen again. Even if they are not detecting, dolphins still emit ultrasonic waves to distinguish enemies and partners. Now there are three submarines, two ships and many murlocs heading towards the gathering place of dolphins.

Rushed there, it seems that the Zhepeng people noticed that the situation had changed.

"An Qi, hurry up and tell the dolphins to disperse and get out of there." Liang Shuang rushed to the console, grabbed the headset, and almost shouted at An Qi.

"Where to leave? We are resting on the island?"

Angel's lazy voice came from the communicator. Judging from the positioning of the signal sent back, Angel was about a nautical mile away from the dolphin pod.

"Didn't I let you rest for half a day? Why are you still in the same place now? There are three submarines and two ships approaching the dolphins. You are in danger."

Liang Shuang had no time to blame An Qi, it was still important for them to escape for their lives.

"Ah, what should I do, what should I do? Luffy, think of a solution quickly."

An Qi hurriedly pushed Luffy who was sleeping. This guy only eats and sleeps. The more critical the moment, the more critical the moment.

"What's wrong, let me sleep a little longer." Luffy turned over and ignored An Qi.

"Luffy, I hate you so much." An Qi stamped her little foot, but there was nothing she could do. However, she rolled her eyes, and in a hurry, she shouted into Luffy's ear, "Help, help."

This trick worked as expected. Luffy got up in a hurry, grabbed the dagger and protected it in front of An Qi, "What's going on?"

An Qi's cry for help startled Lin Huan and others. He quickly ran to the third floor of the Princess Nier, where there was a helicopter. For the sake of Luffy and An Qi, he ignored the risk of exposure and decided to use the best possible method.

Hurrying over as fast as possible. Yingmiao was worried that Lin Huan was alone. Like a black spider, she climbed directly to the third floor along the glass, opened the elevator, and started the plane.

"Anqi, Anqi." Liang Shuang shouted into the headset. You must know that Anqi is a key figure in the plan to find Daxizhou. If you lose her, you can only find another way.

Although An Qi is the princess of Shi Company and her life is safe, being kidnapped as Lin Hun's partner will always put unreasonable pressure on Lin Hun.

"I'm fine. Show me the route and method of escape."

An Qi calmed down a bit, cleared her thoughts, and asked Liang Shuang for help.

"The submarine will arrive in fifteen minutes, and the two ships will arrive in five minutes. Now evacuate the dolphins, in groups of ten, and flee. You and Luffy had better find a place to hide, and Lin Hun will go to pick you up.

"

"Maximum speed, low altitude driving."
