The anti-gravity engine pushed the Explorer to rise steadily into the air, quickly surpassing the height of the floating island fortress. Then the spacecraft continued to climb, and the altitude continued to increase, and the surrounding temperature began to drop. Soon the temperature outside the spacecraft dropped below zero degrees, and the light began to dim.

In space exploration, the most difficult step is to let the heavy spacecraft break away from the earth and enter space. In order to fight gravity, at least 90% of the fuel carried on the rocket was lost in this process. However, in Plandal, due to the existence of prehistoric black technology such as the Goblin Gravity Well, as well as the existence of various technologies such as floating stones and anti-gravity magic, Tang En and others can overtake, quickly break through key technologies, and enter the space field.

This smooth climbing experience made the passengers on the spacecraft feel very fresh, especially those strong men who have never left Plandal.

They looked down at the earth through the porthole. The earth became farther and farther away, and the flat land began to appear in arc shapes. As their heights further climbed, soon the light and dark dividing line of Plandal appeared in their field of vision.

"Now we have arrived at the same temperature, and the temperature outside is about zero degrees..."

Rivez was stunned: "Huh? No, the temperature just now has dropped to more than minus forty degrees Celsius? Why has the height increased, and the temperature outside increased instead?"

Croto explained: "That's because the strata is rich in ozone, so the upper part of it is heated because it absorbs a lot of ultraviolet rays from the sun, so the temperature will rise due to the altitude. The temperature at the top of the strata hovers around minus three degrees, which is almost the same as the ground temperature. However, after breaking through this area, the temperature will drop with the altitude again, and it will soon drop to more than minus two hundred degrees, which is very terrible."

It is difficult for ordinary people to understand what the concept is more than 200 degrees below zero. Cloto had to personally demonstrate to him what it feels like, he controlled the robotic arm, threw a fruit into space, and then gently knocked it, and it turned into dust.

Rivez shivered when he saw this scene: "Will the spaceship we are riding turn into pieces, right?"

Cloto said angrily: "If even such a problem cannot be solved, will we still dare to come to space?"

His words inadvertently made the others feel at ease. Although most of the people here are famous strong men, they have never tried it themselves, and none of them can guarantee that they can survive in the universe.

After breaking through the same stratosphere, the altitude has exceeded 80 kilometers. Then the anti-gravity engine is turned off and the power source is smoothly switched to the magic engine. After the spacecraft adjusts its attitude, the bow of the ship aims at the distance Lolita, and then a light blue magic torrent ejects from the tail, pushing the spacecraft to accelerate and fly towards Lolita.

In space exploration, in addition to the initial stage of the planet's atmosphere that is very difficult to break through, another very difficult technical problem is the source of the engine power of the spacecraft during distant space travel.

Traditional working fluid engines propel the aircraft forward through continuous consumption of fuel. The technology of this engine is relatively simple, but the problem is that the working fluid engine needs to consume a lot of fuel to push the aircraft to reach its destination. The more fuel, the greater the driving force required, and the more difficult it is to get out of the planet... This is a vicious cycle.

In space travel, the best choice is to have no working fluid engines, but physics cannot allow such a fantastic engine to appear (emdrive cannot be considered a success for the time being, so it is not considered). Even in the world of Plandal, it is impossible to achieve without working fluid engines.

However, in this world, there is a very cheap energy with a very large unit energy density, which is magic.

The void energy decays into secret energy, and the secret energy decays into magic power. After the high-density secret energy decays, magic crystals will be formed. At the same time, after the magic is enriched in the living body, magic cores, magic pools and other things will also form. These are very efficient energy sources.

Therefore, although Tang En has not developed a working fluid-free engine, the energy efficiency ratio of the magic engine is far beyond that of ordinary working fluid-free engines. Therefore, during space travel, he can consume magic power without considering orbital factors and continuously accelerate in a very short time without any scruples, allowing the spacecraft to reach an extremely high speed, so that he can reach Lolita very quickly.

"Is this what you said about weightlessness? Oh, this feeling is really great!"

As the spacecraft got farther and farther away from Plandal, Rivez and the others felt the effect of gravity was disappearing from them. Soon, he could not feel his bloated and heavy body, the feeling of lightness and effortless breathing almost burst into tears.

Although other goblins don’t care about Rivez’s bloated body, there are still many inconveniences in over-obesity that he can’t stand.

“A very fresh feeling.”

Gene closed his eyes and let himself float freely in the cabin: "It's different from using flight techniques and floating techniques. There is a...a more free and relaxing feeling, just like his body has disappeared."

The others were also experiencing a fresh experience of weightlessness at this time. Even Egwen, who had never spoken, had a look of surprise now.

Tang En, who experienced weightlessness for the first time, was almost the same as them now, and was as excited as a child.

Just as they were having fun, the Explorer suddenly sounded an alarm: "Warning, a large unknown object was found in front of the route, and it is expected to impact in one minute."

After hearing the alarm, Tang En and the others were all stunned, and immediately followed him and Cloto back to the front of the console: "Show the obstacle image!"

The next moment, an image of the detected object was projected in the center of the hall.

"hiss!"

Tang En took a breath of air conditioning the moment he saw that thing, and he couldn't help but tremble.

It was a space base that was very damaged and had almost lost its complete appearance and was floating in the universe.

"What is that?"

After seeing the projection in the hall, Yustisa and the others were stunned. The structure and appearance of this kind of thing were contrary to their common sense, so they could not understand it.

"space station."

Tang En murmured: "I'm afraid it's a space station left by prehistoric civilizations that have been floating in space for thousands of years."

According to common sense, a space station that has lost its power cannot float in space for so long. It will be affected by the planet's gravity and gradually approach the planet, and eventually be affected by atmospheric friction and slower speed. Then it falls down, either burning out in the atmosphere or falling into the sea.

But now, what appeared in front of them was a space station that was seriously damaged and could not even distinguish its appearance... This is very unscientific.

The overall structure of this space station is on the verge of collapse, most areas have been distorted and deformed, and some of them seem to be hit by asteroids so they are severely damaged. The overall look is riddled with holes and has no potential value at all.

Perhaps, its only value now is to tell Tang En and others that there was an extremely developed prehistoric civilization in this world.

"This should be the space station that survived the disaster ten thousand years ago."

Yustisa said slowly: "If it was hit by a positive impact, it would not have existed now."

"The question is, are there anything that has recycling value?"

Tang En was more concerned about the information of prehistoric civilization.

"I'm afraid it's difficult. Even if there is still some at the beginning, after so many years of radiation erosion, it may not be left."

The environment in space is very harsh. The huge temperature difference and strong radiation environment are not good for data preservation. Moreover, the entire space station has lost its protective environment, so it is impossible for something to be left behind.

"That's it."

Tang En gave up his plan to slow down and directly notified Explorer to change the route, bypassed the obstacles and continued to fly towards Lolita.

Perhaps, that space station was once glorious, but now, it is just a ghost floating in space and has no value.

After skipping through the dark space station side, the Explorer continued to fly towards Lolita at an extremely high speed.

More than ten hours passed in a blink of an eye, and Explorer soon approached Lolita and began to enter the reverse push-down mode. At this time, people on the spacecraft could even see the crater above Lolita with their naked eyes.

Looking at Lolita getting closer and closer, the people on the spacecraft finally understood why Lolita was a pink satellite. A pink crystal grew everywhere on the surface of Lolita. A large number of pink crystals formed huge crystal clusters up to kilometers, refracting the light from Lumbica, so the people in Plandal saw pink.

"Is this another kind of magic crystal?"

Angus looked at the huge crystal cluster with anticipation: "If you guessed correctly, the magic power contained in this magic crystal may be stronger than what we are using now!"

After hearing what he said, Tang En suddenly began to look forward to it. If the pink crystal cluster was really another energy form after the decay of the ghost energy, their choice would be even more.

A moment later, a sudden scream of exclamation sounded from the spacecraft, and the passengers gathered quickly next to the porthole and rushed to look outside.

"Oh my god! This, this is simply amazing!"

"At this point, I finally understand how important the space exploration program that His Majesty Tang En has been promoting has..."

"Then, is it the evidence left to prehistoric civilization?"
