Northwest of Jeongkook, Aviation Training Base No. 7.

Even in winter, the midday sun is still dazzling, but in the near-enclosed training base, sun lamps are often used instead of natural light to simulate lighting in various situations – in theory, it is easy to warm up the interior space to more than 200 degrees even with strong light.

Of course, it can also be completely shut down, and through the formation, the internal energy is extracted, causing the internal space to cool down rapidly to below minus 150 degrees.

At this time, it can be seen that the entire huge test area, which covers an area of more than nine square kilometers, is a dull silence, and the ground in the test area is full of potholes of gray rock and dusty materials, and occasionally some large and small craters, whether man-made or naturally formed, can be seen.

If someone were in this dark and silent environment, they would definitely be surprised to find that in this huge test area, which was enclosed by a layer of special materials and magic circles, it was actually a vacuum like cosmic space! Not only that, but if this person can still see radiation, he can perceive it, and the high-energy radiation in this area, such as strong particle radiation, is far beyond the general standard.

It's ...... It's like the moon.

And in the center of this huge, moon-like test area, a blue-purple spiritual light could be seen, which lit up as quickly as a torch, illuminating half of the base.

[The temperature difference between the surface of the moon is extremely large, and the temperature can reach 120 degrees to 150 degrees Celsius during the day when the sun is directly rayed, and the surface temperature will drop by minus 180 degrees at night. 】

[We have tested it before, Professor Su, you can withstand an ultra-high temperature environment of more than 200 degrees, not only can you move freely, but you can even absorb the heat energy in this high temperature environment for your own use...... Next, it is time to test the low temperature environment resistance of about minus 150 degrees. 】

In the center of the aura, a figure who was not wearing any space suit or protective clothing was carrying a spear with a smooth shape and a silver and cyan body, and he was wearing a fixed contact part in his left ear, and hearing the voice of Yu Sheng behind him, Su Sun replied calmly: "No problem, although I don't like very cold weather, but it should not be difficult to overcome it at minus one hundred and fifty degrees." ”

Although it is said, the entire test area is in a complete vacuum state, and Su Sun is actually directly through the 'Soul Communication Plug-in' newly developed by Yansheng in the recent period, directly converting the thoughts in his mind into electronic signals and transmitting them to distant observers.

[I understand, after all, the dragon was indeed defeated by the ice. 】

The voice from the earphones was quite funny, and Su Sun also asked in surprise: "Hey, Yusheng, you also play Elf Treasure X Dream?" ”

[No, I don't play, but my little daughter loves to play.] This year's Yusheng has been in office for less than ten years, and he is still quite young, and his communication is not rigid: [Okay, Professor Su, just now we have proved that you can completely use pure physical body, and you can move on the surface of the moon under direct sunlight, and your physical activities have completely eliminated oxygen, and your adaptation to various high-pressure and low-pressure environments is also very perfect...... Truth be told, it's as if your physical body was born to move in space. 】

[I even have some doubts, is your original source of dragon blood a kind of divine dragon living in space?] 】

"Maybe, maybe it's some kind of Elemental Magnetic Dragon, an Aether Dragon."

Su Sun snorted haha - there are dragons and snakes that can survive in the sky, and Su Sun has no doubt that his true body in the future can definitely act like a spaceship in the sky, but now he is still far away: "Let's start the experiment first." ”

[Then get ready to begin.] 】

Without much conversation, after a few moments of greeting, as the steel dome of the entire full-coverage closed testing area began to operate, the magic circles inscribed on it began to light up one by one and began to move rapidly.

And with the activation of the magic circle, it began to extract energy, and in the test area, the temperature that was originally as high as nearly 100 degrees suddenly began to fall off a cliff - in just three seconds, the violent temperature difference conversion of more than 200 degrees was achieved, and in an instant, except for a circular environment centered on Su Day, it was enough to sweep the cold wave of steel jelly that was comparable to a cream biscuit.

In the thermal lens, it's as if the whole world has turned from red to blue.

It is said that it is a cold wave, but in fact, there is no wind, no water, and no cold air.

However, this cold wave, before it approached Su Day, was blocked by an incomparably thick spiritual power barrier.

"Although the block can be blocked, but it is more than 100 degrees below zero, what does it feel like......

After wrapping his whole body with spiritual power and maintaining his body temperature, Su Yan stretched out his hand with curiosity, passed through his spiritual power barrier, and reached out to the outside world—suddenly, he raised his eyebrows: "Yo ho, it's a little interesting." ”

He withdrew his hand, and in just a few seconds, the surface of his arm was already slightly stiffened - if Su Sun didn't use the aura to cover himself and maintain a certain temperature, then even if he came to the extremely low temperature cosmic space, his body would inevitably stiffen, and it would even be difficult to move.

"Sure enough, it's still a bit of a hassle. Dragons are frozen and really not just a game thing. ”

At this time, it is already obvious that the current Su Sun is conducting experiments on future exploration to the moon.

Originally, this kind of experiment should have been carried out in a heavy space protective suit, but because Su Sun was the only commander-level combat power, and with his life form, ordinary space suits were useless at all, and could only hinder his actions, so unlike others, Su Sun participated in a special separate test.

Although he also has a certain amount of data to explore Su Sun's current body, Su Sun doesn't care, and in fact, in the previous high-temperature environment test, Su Sun did show extremely powerful extraterrestrial combat capabilities.

Even in the case of vacuum, high radiation, ultra-high temperature, and low gravity simulated moon, Su Tian was still able to control his actions very well, even if he was acting at hypersonic speed, running back and forth in the test area, he did not see any runaway calls.

Even, without atmospheric obstructions, he was even able to achieve a peculiar inertia-free steering and high-speed maneuvering.

However, now, in the ultra-low temperature environment below minus 150 degrees, even Su Tian feels quite limited.

"The only weakness of the immortal blood is that in the extremely cold environment, the regeneration ability will be greatly weakened - although as my strength becomes stronger, the effect of low temperature will become smaller and smaller, but even the commander level cannot be completely ignored."

Although the stiffness in his arm only disappeared in an instant, Su Sun was still a little worried: "This is actually my weakness - and I really haven't encountered an opponent who is good at using frost or cold temperature combat. And the truly strong, or in other words, the perfect lifeform, does not need weaknesses! ”

This must be overcome!

Although Su Sun thought a lot in his heart, for Yu Sheng and the others who observed Su Sun's test data, only a few seconds had passed, and after seeing that Su Sun's aura shield could indeed ensure his body temperature and completely isolate the influence of the surrounding cold environment on his body, he nodded with satisfaction, and then said: [Professor Su, how long can your shield last? This will determine the time we set for you to have a safe event on a moonlit night in the future. 】

"This aura shield?"

For Yu Sheng's words, Su Yan was slightly stunned, and then said with a smile: "This thing is just the spiritual flow that I naturally overflow, but I usually move around the city, and I lock it on the surface of my body and it does not spread." ”

"This kind of shield, I can last a lifetime."

【…… That's ......]

The voice in the communication was silent for a few seconds, and after a few seconds, he said again: [So, can you fight? In this case. 】

"No problem."

Without saying much, Su Yan directly raised the silver-cyan spear he was holding tightly in his right hand.

Spear of the World Tree.

A month ago, the branch of the Nine Realms Tree, which was given by the Europa Alliance, was delivered to the Zhengguo official, and under Su Sun's commission, Jeongkook's best transcendent creator craftsman, according to Su Sun's request, created a spear with an extremely simple and smooth shape.

The attributes of the branches of the Nine Realms Tree vary according to the world they pass through, and the branch given to Su Sun passes through the 'Underworld', so its attributes are not only in the wood genus, but also have a kind of incomparably strong power of yin spirits and ghosts.

This is certainly powerful, but it is not quite in line with Su Sun himself, at least, it is not in line with Su Sun's image to the public - although his image is indeed not a good person now, at least Su Sun should not be the type who holds a sinister spear and is surrounded by countless ghosts as soon as he appears.

Even if they are all demon kings, Su Sun's design elements should also rely on the demon dragon, lava and thunder.

In this regard, the craftsman of Zhengguo adopted a peculiar 'birth method', he buried this sacred tree branch into the peach forest of Kunlun Mountain, and used the power of another divine tree to provoke the antagonistic nature of the wood power of the world tree trunk itself, purified the yin spirit attribute that originated from the underworld, and turned it into a more pure soul power, and then asked Su Sun to provide a little blood as an enchanting material, casting it into an extremely powerful 'Yin Thunder Spear'.

Yin Thunder, Silent Thunder, simply put, this is a spear that can hit the soul directly, has a great bonus to the spirit, and has the power of thunder.

However, the bonus to the spirit body does not mean that the destructive power of this spear itself in the material world is lower than that of ordinary magic weapons.

Clenching the spear in his hand, the muscles of Su Sun's right arm knotted, and the violent cyan purple spiritual power was like a tide pouring into the ruins into the World Tree Spear, causing an obvious spiritual power pattern to light up on the surface of the arm—and after two seconds of charging, the surface of the silver-cyan World Tree Spear suddenly shone brightly!

Airplanes!

There was no air, no sound in the vacuum, only the aura vibrating and the soul rippling.

In less than a second, the light on the surface of this radiant spear suddenly shrank and turned into invisible, and then, its entire body seemed to disappear, or even escaped into the spirit world, completely disappearing into the material world!

Even, even the Jeongkook researchers, who had been monitoring from afar, were shocked to find that the World Tree Spear in Su Sun's hand had really disappeared completely.

By the time it reappeared, it was a small crater two kilometers away.

There was no sound, the dim thunder light spread, decomposing the silver-gray soil and rocks, only to see the thunder of spiritual power like water waves, and a few seconds later, a huge sinkhole with a radius of more than thirty meters appeared on the surface, replacing the original crater, and the spear of the world tree that restored the silver-blue color was erected in the center of this crater.

"It took 0.09 seconds! The distance of 2400 meters was crossed in such a little time! ”

A researcher who observed the data exclaimed: "The speed of the World Tree throwing guns is more than sixty-six times the speed of sound?!" It's horrible! ”

[Nope.] 】

On the side, the prosthetic eye in his left eye flashed with red light, Yu Sheng stared at Su Sun, and the spear of the World Tree in the distance, he showed a smile: [After the spear of the World Tree was projected, it escaped into the spirit world and turned into a pure spirit, and the speed of the spirit body is difficult for us to react to in the material, if the impact force alone is at the level of six times the speed of sound to eight times the speed of sound in the earth environment. 】

[It is worthy of being a throwing spear forged by a divine wood containing the power of the Yin Spirit, and with the power of Professor Su, it is really difficult to resist. 】

This is, Yin Thunder.

However, for the destructive power of this blow, Su Yan himself was still a little dissatisfied.

"I feel that in terms of lethality, this is similar to that of ordinary high-performance missiles."

Raising his hand and using his spiritual power to recall the nearly two-meter-long silver-cyan throwing gun, Su Yan shook his head slightly: "Actually, in terms of the collateral lethality brought by the shock wave, it is not as good as a missile." ”

[Be content, Professor Su, do you know how much a high-performance missile you said costs? Not counting the warheads, they are nearly 100 million. 】

Regarding Su Sun's obviously too greedy idea, Yu Sheng could only sigh and say: [Anyway, you can exert such combat power in the lunar environment, which is already beyond our phenomenon - except for you, the other explorers have all shown a decrease in strength of different sizes in the simulation experiments. 】

[However, they were just adding to the head...... Since Professor Su can guarantee your complete combat effectiveness, then it seems that we will be able to deal with the possible crisis. 】

"Hmm."

In this regard, Su Tian nodded slightly.

He naturally knew what the danger in Yusheng's mouth was.

Naturally, there are aliens in the spaceship who may be alive.

Or ...... Alien monsters.
