The two waited patiently for a while, and only after the Extreme Realm Clan's fleet had withdrawn did they continue on their way, heading towards the ice to be exact. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

Although those powerful Extreme Realm soldiers had left, for the sake of safety, Yang Yi and Amy did not use brute force to penetrate the ice, because the Extreme Realm fleet was likely to leave a small probe behind when it withdrew, and it would be able to find anomalies on the home planet. Fortunately, Yang Yi brought a set of standard combat equipment for the Human Expeditionary Force, including a battery-powered thermal energy generator.

It's just that the two underestimated the thickness of the ice.

According to Amy, the Ocean of Storms is the largest ocean on the home planet of the Polar Realm, with a maximum depth of more than fifty kilometers. When the home star of the Polar Realm orbits to aphelion, there is only liquid water near the crater. More than 4,000 years ago, when the Arctic Race settled here, the pioneers of the Galactic Alliance placed some of the severely damaged and unusable spaceships near several large volcanic craters, and used the large Origin Energy Converters of these ships to create some small ecosystems that could allow the Arctic to survive in the harsh environment. Over the next few hundred years, the Polar Realm relied on these small biospheres to survive on their home planet, and gradually grew to become a second-rate top civilization. It is precisely because of this that these ecospheres must be the holy places of the Extreme Realm Clan.

It's just that these ecospheres are all at the bottom of the storm ocean, and at the deepest depths.

Now, the planet has orbited near aphelion, and the storm ocean has long been frozen. In other words, Yang Yi and Amy are faced with dozens of kilometers of ice in front of them.

Although it is not difficult for Yang Yi and Amy to penetrate the ice layer dozens of kilometers thick, it is obviously a big trouble to rely on a single heat generator to create a passage tens of kilometers long in the ice, and even if it can be done, it will take a lot of time.

Over the next few hours, the two advanced less than a kilometer. At this rate, it will take several days to break through the ice.

Even if it won't be discovered by the defenders of the Extreme Realm Clan, it can't be delayed for so long. Quite simply, it won't be long before the defenders of the Extreme Realm will be able to discover that the previous anomalous origin fluctuations came from some detectors. As long as the commander of the Arctic Clan defenders was not too stupid, he could think of the intruders using the detector as bait just to lure them away. Next, the defenders of the Arctic Realm will definitely lock down the star system where the home planet is located, and then send out a large army to carry out a carpet search. If this matter attracts the attention of the royal family of the Extreme Realm, it will definitely send powerful members of the royal family to come, and it will also strengthen the defense of the Holy Land. Even if Yang Yi and Amy were not discovered, they broke through the ice a few days later and arrived near the Holy Land of the Extreme Realm, what was waiting for them was likely to be the royal guards of the Extreme Clan, or even the queen of the Extreme Clan.

"We have to hurry, if we delay any longer, I'm afraid the consequences will be unpredictable."

Amy nodded, indicating that she understood what Yang Yi meant.

"Wait, I'm going to open the way in front, you're following closely, don't pull down." Yang Yi let out a long breath and said, "As expected, those defenders left the probe, and maybe a few powerful guys left on the home planet, but I can't sense their existence, maybe they don't use their original energy anymore." In other words, we will soon be exposed, so we can only keep moving forward. If the situation is really not good, we must withdraw immediately. Anyway, we can't just leave, we have to try. Big deal, think of other ways to check here in the future. Remember, let me know immediately if anything out of the ordinary happens. ”

Amy nodded in agreement and didn't say anything more.

Yang Yi didn't ramble anymore, and when Amy was ready, he propped up the energy barrier, and at the same time concentrated a force of original energy between his hands.

As the original energy shot out of Yang Yi's hand, a straight downward passage appeared under his feet.

The huge amount of heat released during the conversion of the original energy instantly melted the nearby ice, which was equivalent to burning a passage in the ice. As the ice melted and vaporized, the passage was filled with white vapour. It's just that for Yang Yi, these water mist are not a problem at all.

Yang Yi took the lead, followed by Amy.

Obviously, for Yang Yi, it is easy to penetrate the ice layer dozens of kilometers thick.

A few minutes later, the two pierced through the ice.

As Amy said, beneath the ice is a vast ocean, a city built on the bottom of the sea, or a city that has long been abandoned.

Although in the beginning, the Arctic could only live in the ecosystem built by the pioneers, after hundreds of years of development, especially after becoming a second-rate top civilization, the Arctic Clan's living range has expanded to the entire Storm Ocean, and the entire underwater world has been built into a city. In its heyday, this undersea city was inhabited by billions of Extreme Realm people, as well as envoys from tens of thousands of civilizations. It's a pity that the good times didn't last long. Hundreds of years later, the Polar Realm migrated as a whole, and the home planet became a forbidden area for idlers, and this magnificent underwater city also declined. Thousands of years later, all that remains is ruins.

Seeing the ruins in front of him, Yang Yi also sighed.

Even if it's just a ruin, you can imagine how prosperous it was more than 4,000 years ago. However, not everyone is suitable for living here.

The point is, the city was built on the bottom of the sea.

"Over there."

Hearing Amy's words, Yang Yi turned to look at her, and then flew in the direction Amy pointed.

Although the resistance of the sea water is great, it has not become a problem for Yang Yi and Amy. In fact, both of them have energy barriers, so they don't come into contact with the sea.

After a while, there was a light ahead.

It was an undersea crater, and the light came from magma. It's just that the crater is shrouded in a huge energy barrier, and after the magma reaches the crater, it is blocked by the energy barrier, and instead of spewing out of the crater, it quickly cools down and then sinks.

When he came to the vicinity of the crater, Yang Yi saw that the energy barrier came from under the surface near the crater.

That is, the device that creates the energy barrier is underground.

In addition, the crater is full of solid lava, that is, cooled magma. Apparently, the volcano has been around for a long time and has been erupting, constantly spewing magma outward. The energy barrier that envelops the crater is not really trying to stop the magma from coming out, but to stop the energy from being lost. It is precisely the existence of this energy barrier that the magma in the crater has never cooled.

"Is this it?"

"It should be here." Amy nodded slightly and said, "In the beginning, those ships were placed near the crater. Although there is a large Kinetic Energy Converter on the ship, it is not possible to work all the time due to technical limitations, and regular maintenance and inspection are required. In order to secure the environment in the biosphere, it is necessary to use the energy of the volcano. To put it simply, when the large Origin Converter on the spacecraft is undergoing maintenance, the energy provided by the volcano drives the operation of the ecological device to ensure that the environment in the biosphere does not deteriorate rapidly. It is precisely because of this that the crater must be protected with an energy barrier. As expected, the ship is just below the surface. ”

"We went in through the crater."

Amy was stunned for a moment, and then nodded, indicating that she understood what Yang Yi meant.

Although it is not difficult to make a passage on the ground, they do not know the exact location of the ship, which may damage the ship. There is no such problem when entering from the crater, and as for the high temperature in the volcano, it is obviously nothing to the two powerhouses with holy weapons. In addition, if a hole is made in the ground, it will reveal the whereabouts of the whereabouts, leaving at least traces that two people have been here.

Entering the crater, Amy followed Yang Yi closely.

Although the high temperature is not a threat, inside the crater, Amy can't see anything, and her perception of original energy fluctuations is obviously not as good as Yang Yi's.

Fortunately, Yang Yi knew which direction to go.

In a short time, the two of them emerged from the lava. Still inside the volcano, it's just inside a huge chamber made of some special material.

"This ......"

"We should be inside the ship." Yang Yi pointed to the door behind him, and that's where they came in, but Amy hadn't seen it before. "Obviously, the materials used to make the ship's hull can withstand the high temperatures of magma, and there is an energy cycle device on the ship."

Amy nodded, not saying anything more.

They were indeed inside the ship, a ship built more than 15,000 years ago to send refugees from the Galactic Alliance to the Southern Alpha System.

Of course, this is also a spaceship built by humans more than 15,000 years ago with the most advanced technology at the time.

Because they were built with long-distance travel across star systems in mind, these ships are equipped with large, powerful primordial converters and well-developed ecosystems. To put it simply, a spaceship is a small ecosystem that can continue to operate for tens of thousands of years. As long as the Origin Converter on the ship is still working, the biome on the ship will be able to function normally. It's just that when these spacecraft were built, no one knew what the situation of the vast universe between the star systems was, such as whether there was enough original energy, so human scientists thought that it was necessary to improve the efficiency of energy utilization when they were designed, so they equipped the spacecraft with an energy circulation system. To put it simply, it is to minimize losses and make full use of limited energy.

As for the materials from which the hull is made, especially the outer shell, it is not only extremely strong, but also resistant to high temperatures, and still retains its basic physical properties in an environment with large temperature differences. Otherwise, these ships would not have been able to remain intact during the long voyage.

Obviously, the ship is certainly designed to last more than 10,000 years.

As long as it is not damaged, perhaps the equipment on this ship will continue to operate for tens of thousands of years, if not longer. In fact, this is enough to show that the human beings of the Second Age are indeed powerful, and the technology they have mastered is also extremely advanced, otherwise it would be impossible to build such a durable spaceship.
