This strange layered structure creates a bizarre landscape, and people are like entering an aquarium. They walk in a glass tunnel, and there are rare fish swimming on land above them from time to time, which is a feast for the eyes.

However, there is no sea water in this aquarium, and the flying fish monsters that are enough to kill people are wandering above their heads. These fish monsters are fighting fiercely with the Hunyuan Body Raiders. The most funny thing is Abathur, who paraded in the buoyancy zone, did what he did during the diving process, raised his head from time to time, grabbed some fish monsters from the weightless area and stuffed them into his mouth, like a child who fell into the candy world, eating all the way.

As creatures that can collect 200 gas, the attack power of the fish monster is actually very high. This can be seen from the fact that they can cause corrosion damage to the armor of the Angels. Hunyuan Body Raiders will also be injured in battle. However, what made Tang Fang exclaimed was that after killing the fish monster, they relied on devouring the biomass of the death target to quickly heal their own scars.

The tunnel is very long, and you can't see the night sky from the ground to the sky. The fish monsters that occasionally penetrate into the buoyancy layer are inevitably scary, and some will be dismembered by Abathur and become disgusting corpses.

The crystal lattice that emits a faint light under your feet is very beautiful, but the night sky above your head is not charming at all.

While the team was moving forward silently, the detector team sent new scanning data. Emma updated the structural model of the Tiankeng based on this information and projected it into Tang Fang's mind.

"Commander, according to the latest information obtained by scanning the detector, the sinkhole does not enter the core of the wandering planet. It has a slight inclination during the downward process, just like a tangent line at a point of arc, it is wiped through the edge of the core, and then connects the core space through a curve similar to an L-shaped curve."

Tang Fang frowned when he heard this, and his flight speed was slightly slower. According to Emma, ​​the sinkhole was a tilted L-shaped pipe that extended from the surface to the core.

After seeing the Sita quadrant, he knew very well that the cosmic civilizations to which the T-star and the Ipsilon people belonged were capable of hollowing out the center of the earth and had the technical technology to build scientific and technological equipment that simulated the earth's core function.

If this ruin is really as previously speculated, it is not a ruin of the Ipsilons, but their hostile race, the ruin of the T-Star people, then... what is it for?

This reminded him of the strange situation that Sita imagined. The teleportation platform of the outer Sita quadrant had obvious e-grain, which proved that the builder was the Ipsilon, but the strange black ball in the inner Sita quadrant did not see any e-grain from the surface to the core, and a corpse of a T-star man was found inside. At that time, I doubted whether the black ball was robbed by the Ipsilon man from the hands of the hostile forces. The West Sita quadrant was a prison-like space station for the Ipsilon man.

The Ipsilon civilization withered, and the lost land was deserted due to war. The two ancient cosmic civilizations were like the willow catkins that froze when they came and quietly left in the long river of history, leaving only countless mysteries and marks of civilization.

"Is it possible..." He suddenly thought of a possibility that this wandering planet would be a mobile military space station of the T-Star people? The gravitational disordered area and "asteroid armor" on its surface show that the wandering planet has strong defense power, and the sinkhole can store a large number of warships. Even ships of the level of the Fearless Commander-level Fortress are not a problem. Moreover, according to Hank King's description of the encounters of the 42nd Fleet, the 87th Fleet, the Cang Lion Fleet, and the Phantom Fleet, it seems to have interstellar navigation capabilities.

What does Yemenggard have to do with this ruin? If this is not its home, is it like an evil eye or a giant snake, attracted by the zero-prime inside the ruins before entering this ruins?

Yingluo didn't have the chance to tell him that Yamengjiat was injured before leaving the sinkhole, and that there were things he was afraid of in the ruins. He only knew that Yamengjiat was seriously injured by the Void Glow Ship, and the T-energy Stone on his forehead was broken, and ended up like Yingluo, which was considered avenging the girl with a single arrow, but he himself was not satisfied with this result.

After the ruins appeared and entered the sinkhole, especially when he found that the Angel was besieged by fish monsters, he also suspected that there was another danger in the ruins. Ye Mengjia did not want to protect his home to attack the Angel, but for another reason.

But it's just a suspicion. If you haven't entered the ruins to find out the truth, you can only be suspicion and speculation.

Everyone continued to walk forward for a while, and according to the data from the detector, they had left the mantle area and entered the core. The foot was still under their feet. The only difference was that the brightness had increased, not as dim as the hive lattice in the sinkhole area. The buoyancy layer and weightless area, including those fish monsters, also did not change. The Hunyuan Body Raiders tirelessly killed them and swallowed them. Abathur still took down a piece of minced meat from time to time and threw it into his mouth, treating the flying fish monster that was enough to kill people as delicious sashimi.

Valentine said, "Your eating is so ugly. Could it be that they are more delicious than larvae?"

Abathur said: "It tastes good...you can try it."

The meat on the old man's cheek shivered, "Forget it, I'm still used to eating Western food than Japanese cuisine."

Walton suddenly envied the one floating above his head. Although he looked ugly and his living habits were not worthy of compliment. At least he had a companion and had no time to stumble or argue. It was also a pleasure.

My wife... My wife, I am always with you. Valentine has no wife or children, and she has contributed her youth and energy to biological science. Now she has become a Zerg scientist who is both a teacher and a friend, and this result is really good.

At this moment, Captain Tang, who was leading the way, suddenly braked and stopped. The next second, Tang Lin, Walton, and the veteran, a low and serious question came from the communicator, "Did you hear it?"

"What did you hear?" Tang Lin asked back. Aros shook his head. Before Walton woke up from his previous sigh, he subconsciously said: "Did Valentine and Abathur flirt with each other?"

Before Tang Fang could respond, the old man looked at Walton with an angry look on his face, "Damn kid, I have the will to say what I just said again."

Of course, Walton did not have the courage to say what he had just said. As the person in charge of the Angel's medical resources, he had ten thousand ways to avenge today in his future life, so the man who chased the wind could only express his surrender with silence.

Tang Fang did not care about the conversation between the two, and asked again in a very serious tone, "You really didn't hear that voice? A woman's voice... was singing."

Aros listened for a while and shook his head hard, "I heard no strange sounds."

"Brother, are you too tired?" Tang Lin then denied: "Apart from the sound of the flames, I didn't hear any woman's voice, let alone rap."

Tang Lin's physical fitness is higher than that of ordinary people, so his ears are naturally sharper. Even he said he did not hear the sound, which only proves that Tang Fang was wrong, which is probably because of auditory hallucinations caused by excessive mental fatigue.

Walton said, "I've been walking for so long, do you want to take a break?" He felt that this might help Captain Tang.

Tang Fang did not respond to his kindness, but looked up at the hive lattice that was brighter at the end of his vision.

"Gret...I'm here... waiting for you, Tang...Fang?Gret..." At this moment, the female voice humming an unknown song sounded again, and she actually called out his name. At the same time, the Ipsilon rune on her forehead jumped gently, with a low force, extremely slight, but very real.

His face became even more gloomy. He looked back at the three of them, and saw that they still had no reaction. He knew that only he could hear the voice. This might be related to the Ipsilon rune on his forehead. He thought to himself, could the owner of the voice in front was an Ipsilon man? But why did she know her name?

Frowning and thinking for a moment, his mind moved slightly, summoned four Dark Templar Warriors from the system space, and at the same time issued an order to the 5 Hunyuan Body Raiders in the Weightless Area, and then said to Tang Lin and the other two: "You are waiting for me here, I'll go ahead and see. If there is no danger, I'll inform you to come here."

Tang Lin shook his head and said, "No, I want to go with you." He knew that Tang Fang would not lie. Since he heard that women were singing, this matter would definitely not be fake. Even if the elder brother really had auditory hallucinations because of overwork, he had the more responsibility to take care of him and protect his brother's life safety.

"Do you still remember the three rules when you left the ship? Even if there is really any danger, you will be distracted by the past."

"I can take care of myself." Tang Lin still insisted. The veteran patted his shoulder from behind and shook his head and said, "This ruin gives me a strange feeling. Tang Fang is right. One more person will be more dangerous."

Abathur slowly landed on the inner wall of the crystal from the buoyancy layer, and Valentine advised: "Don't worry, I'm there."

Tang Lin hesitated for a while, finally nodded, no longer insisted, just reminded him, "Be careful."

"I will." After saying that, Tang Fang opened the jet pack and continued to fly forward. Abathur re-entered the buoyancy layer, continued to shake his tail, and followed closely behind him.

Although the female voice that others could not hear did not show murderous aura, it was very pleasant and pleasant. However, in the deepest part of the heart, the voice always gave him a sense of terrain, and the detector's scanning of the surrounding terrain even worsened this feeling of uneasiness. According to the sinkhole model established by Emma, ​​the three people who were stationed in Tang Lin, Aros, and Walton were exactly the junction between the mantle and the core. The more they went in, the more intense the energy reaction was and the temperature was also rising.

A detector and a Dark Templar were sent by him to the core to investigate in advance, but no valuable information was found and the origin of the female voice could not be traced, as if they were directly fed back to the cerebral cortex and not transmitted through air.

If he wants to lift the gravitational blockade in the upper layer of the sinkhole, the easiest and most effective way is to enter the ruins to investigate, find the control center, and obtain control of the ruins. So he has no choice but to take risks with himself and take the chestnut from the fire.

He flew below, Abathur swam above, and 5 Hunyuan Body Raiders were reclaimed from the system space.

Flying forward for about 200km, the light from the inner wall of the crystal under the feet is brighter than the searchlight, which is enough to penetrate the buoyancy layer and illuminate the weightless area above. The number of fish monsters has not decreased, but it is obviously divided into two strands that do not interfere with each other. The fish school above swims outwards and the fish school below swims inwards, forming a cycle.

Flying forward for 50km in such a monotonous background, I suddenly saw a structure similar to the tunnel exit. In the scan of the detector, it was a circular exit, but because the tunnel with a diameter of nearly 100 kilometers is too large for humans to form an intuitive understanding through the human eyes. At the same time, a weak compensatory gravity also came from the feet to balance the increasingly serious sense of weightlessness.

The space inside the tunnel was filled with a turbid gas, making the sky look a little dirty, gray and yellow are ambiguous at the end of the sight, and green and red are broken. The mist rolled in the sky, and the clouds rippled back and forth, stirring those uneven colors together, as if suddenly entering an underground world.

The light on the inner wall of the crystal is very bright, but it cannot illuminate the entire space, so the night grows quietly behind the chaos.

Tang Fang did not stop at the entrance of the cave, and jumped out with Abathur, jumping into the weightless space rendered by color. The weightless area of ​​the tunnel went back and forth, two flying fish were like birds traveling south in autumn, passing through the indifferent clouds and smoke, and sank into the deeper darkness.

"What a good boy... giggle." The female voice that made him care about rang in his mind.

At the same time, the tunnel connecting the core space suddenly changed drastically, and the honeycomb-like crystal lattices increased at extremely fast variance, turning into regular hexagonal prisms, locking the entire tunnel.

Tang Fang was not surprised by this change, nor did he try to leave the core space and turn back the same way. Because he knew that there was no possibility of reaching the safe area before the tunnel was blocked by the regular hexagrams, it would only crush him into a pool of meat paste, and he had not yet found the source of the female voice and the way to remove the gravity well in the sinkhole.

The tunnel nearly 100 kilometers wide is blocked by a crystal wall. The surface of the wall is also composed of lattice structure and is almost integrated with the surrounding environment. If you had not walked out there, you would not have noticed that behind the wall is a tunnel connecting the sky pit.

"Do you want to try to see if it can be opened again?" Valentine said, pointing to the crystal wall that sealed the tunnel.

Tang Fang shook his head and said, "A crystal wall that is hundreds of kilometers...how long do you think it will take to penetrate it."

"Hundreds of kilometers?" Valentine was shocked by the number, "Are you sure?"

"If I'm not mistaken, the entire sinkhole can be filled with those regular hexagonal prisms..."

"Hiss..." The old man took a breath, "This...this is too amazing." Then he thought of Tang Lin, Aros and others in the tunnel, and his color changed drastically, "How are Tang Lin and the others?"

"It's not a problem. Their location is just at the junction between the mantle and the core, and has not been affected by this incident." (To be continued.)
