In a tangled mood, Wei Lingdong walked into the metal cabinet.

To his surprise, as soon as he stepped in with his hind foot, his protective stamina automatically lifted, and the air instantly escaped into the antique sleeping chamber, and he tried to breathe without the slightest discomfort.

The hatch lid was closed, and the Luban robot that had been iterated many times disappeared from his sight in an instant.

The inner walls lit up with a milky white glow, and a message was projected on the slightly worn hatch cover:

You're about to enter the underground base, and get ready for the trial.

"Trials?" Wei Lingdong was puzzled for a moment.

After about a minute, there was a slight feeling of being overweight from the dormant chamber, which was falling like an elevator, and it was supposed to have stopped from the descent process.

The hatch cover slid open, and a huge underground base with bright lights appeared in front of Wei Lingdong's eyes!

This is a purely industrial miracle, with no traces of artificiality!

The whole base is a cube, about 100 meters long, the ground is covered with large and small cube houses, the small one is only two meters long, and the largest one is located in the center, which is twenty meters!

He couldn't imagine how many years it would take to hollow out these million cubic rocks with that robot alone! However, when he thought about the principle of gravity, which he was completely confused about, he was relieved. With the other party's technology, if you still have to dig with brute force, it seems a bit unreasonable.

The entire underground base is filled with air, and its composition is the same as that of Earth, and it is clear that this space is confined and completely internalized.

Wei Lingdong thought of a terrifying fact in his heart:

This is the edge of the solar system, and time should obviously flow at the same speed as Earth. Yuanwang-1 disappeared on December 24, 2045, Celestial Empire time, and it is only June 2048!!

In two and a half years, when was this base established? Looking at the old appearance of the dormant warehouse just now, it should have been brought back from the world after the Yuanwang No. 1 crossed, and it had been used there for a period of time before it looked like this. In addition, the seven iterations of the robot should also take a lot of time, so it is obvious that this base should have been established not long ago, whether it was a year ago or two years ago, Wei Lingdong had no way to guess, and the other party did not inform him.

As his mind turned to this, his gaze was drawn to a colored band of light on the ground, which looked like a virtual road with an arrow in the middle, apparently trying to guide him forward.

Wei Lingdong's feet moved, and he followed the guidance of the light belt. The two-meter-wide virtual road is colored, while the ground in other places is shown in red, obviously this color does not mean safety, and Wei Lingdong will not be stupid enough to try this guess in person.

The road passed through a dense mass of large and small cubes, and it was as if he were strolling on a huge antique circuit board.

The arrow turns right in front of the smallest cube, pointing to the center of the cube, where a door slides open. As a pure rock building, it is silent when it is opened, and this level of craftsmanship is simply killing all skilled craftsmen on the earth.

The virtual projection screen is displayed on the right side of the cube stone house: No. 1 Trial Place, after passing, you can get 1% energy replenishment of the Vientiane Spirit Ball, and the number of challenges will be deducted if you fail, and there are 10 remaining challenges in the current challenge.

“1%！？” Wei Lingdong was speechless, what is this energy enough? At most, it's just a few waves of laser killing knife consumption... It can't be the highest psionic compression!

He then looked down.

Trial Missions:

Challenging the use of a vandal knife without gravity, touching the inner wall of the test site is considered a failure. A 10x Psionic Killing Knife is fired once in the air, and the body displacement does not exceed one centimeter, which is considered a success.

Seeing this condition, he understood that this was a test of his control over all spirits and psionic powers. It seems quite difficult, and the effort is completely disproportionate to the benefit.

In the past, when he used the Killer Knife, he never thought about this kind of boring-looking recoil. Because both the air resistance and the friction of the ground can counteract this insignificant reaction force. Even if it is a fifteen times spiritual energy compressed laser killing knife, the reaction force, or recoil, produced is equivalent to the strength of an ordinary adult's gentle push. You must know that the killing knife is not a kinetic weapon, it is not like traditional thermal firearms, the latter relies on kinetic energy to generate lethality, while the former relies on ultra-high-density energy to cut the target, thus producing an extremely terrifying damage effect.

But now this first test requires him to control the recoil of the Killing Knife. His first instinct was to use the ability to manipulate the air to simultaneously create a thrust behind him to counteract the recoil of his body when he fired the Killing Knife.

The moment he stepped into the stone gate, the gravity outside, which was the same as the earth, disappeared, and his body floated directly inside the two-meter-long cube stone house.

There was plenty of light inside, and he glanced at it, the walls were smooth as mirrors, without any hints or obstacles, and the door was not closed, apparently for him to fire the Killer Knife out of the door.

He tried to activate the protective body, but it turned out to be difficult for him to accept, and the activation failed!

This is a protective body, not the Vientiane Spirit Ball's own Spirit Ball arc shield! Even the abilities that all spirits have already learned have been blocked!

Next, he tried to use the air manipulation ability, and it turned out to be unusable!

It's been more than a minute since I came in, and an indescribable feeling of suffocation came, it was the feeling of not breathing well! Only then did it occur to him that there was no gravity in this small room, and the air was like an invisible jelly frozen in the air and could not circulate normally! The carbon dioxide he exhaled was wrapped around his head!

Originally, with his super body, even if he didn't breathe for half an hour, it would not be fatal, but at this time, he didn't think about the problem of breathing, and when he found out about the problem, there was not much oxygen left in his body. If this continues, what awaits him is the end of carbon dioxide poisoning coma!

Almost without hesitation, he amassed a tenfold Psionic Laser Killing Knife and sent it out.

The white light flashed, and a wave of qi poured out ten meters away from the door, eliminating the killing knife into invisibility. And his body floating in the air was also pushed down against the smooth wall behind him by the reaction force. Wei Lingdong pushed the wall with his backhand, and his body instantly crossed a distance of two meters and returned to the door. At the same time that gravity returned to his body, he stumbled under his feet, the result of not adapting to the sudden change in gravity.

"It's about 50 Newtons of reaction power, such a small force, any one of the weakest air manipulation abilities can cancel it out, but this ability is disabled, what should I do?"

Wei Lingdong fell into deep thought.
