Tiantu Continent does not have the day and night cycle of ordinary planets. There are only two states: "suitable to come out for activities" and "must lie down in the hole". The period of the bright star quickly sweeping through the gravitational barrier lens is the period that divides the two states.

The most important criterion for this state. Alex also knew very well that the dangerous radiation cast by this star would affect his work and rest in the first critical period of the sky and earth, so he kept observing and recording it.

After Liuma repaired the gravitational wave detection radar, the orbits and cycles of the planets around Tiantu have been recorded in detail, but they cannot be taken over and used. For example, this bright star orbits Tiantu once.

It's almost 170 hours, half of which is on the "back" and doesn't produce "cluster radiation" at all; and the other half of the time, it doesn't always cover Alex's head with radiation.

The sky and earth are too large, and the gravitational barrier changes with the terrain. The actual cluster radiation is more like bright spots sweeping across specific areas on the ground. Since light cannot be concentrated in all directions at the same time, the spots

The area in between will become a safe dark area. If you stand still, the light spot of about eight hours will be followed by a four-hour transition and eight hours of safety, and then another four-hour transition.

The next dangerous light spot will be turned on.

"Recording the direction of the movement of the light spot, the shield of the aircraft can last for about ten hours, which can basically guarantee safety." Alex calculated the relationship between the battery capacity and the shield, then scratched his head: "The efficiency of charging and discharging is related to

If not, it is safer to move at the edge of the light spot. The construction and charging will be completed tomorrow, and the test flight will be carried out the day after tomorrow. We must reach the river within one day."

Relying on the internal circulation system of the evolution plug-in, Alex uses food and water very efficiently and can persist for much longer than ordinary people. According to the instructions for use of the evolution plug-in, if he remains still in an underground cave at around zero degrees,

The evolution plug-in allows the composite evolution to maintain a state of hibernation for about six months to wait for rescue. However, Alex is not rescued. He must work to save himself. The physical exertion forces him to replenish water and nutrients in time. The river in the distance

is his best hope.

Although he figured out how to use the corpora, Alex did not change his plan because of this. He knew well that he could not aim too high, so he did not think about using the corpora to transform advanced parts, and focused on the first step.

Bring everything to the river, drink water, and eat. Technology develops in a spiral. Even if you want to overtake in a corner, you need to have a deep foundation first. It cannot be realized automatically when you have an idea. Ai

Ricks continued to hammer on the mining machine, unfolding its wings, building its frame, and installing equipment.

Ding-ding sounds kept coming from the cave, and this unprecedented sound puzzled the surrounding animals. During the interval when the cluster radiation spot passed, some animals came out of the cave and poked their heads around Alex to check.

.

"Animals mainly live underground. It seems that this is the main form of the local ecosystem." Alex looked at the weasel-like creature hiding in the shadow not far away. "Forget it, I'm not hungry yet, and that thing looks...

It's not easy to catch. Alas, it would be better if you brought a double-barreled impact gun. The computing stick can only be used in close combat, and its flying speed after deformation is not as fast as arrows, so its lethality is worrying. If it is picked up by the weasel, the loss will be huge.

too big."

It’s not that you can’t make a crossbow with the equipment on hand, but the priority is not that high. As long as the animals outside don’t disturb him, Alex has no plans to turn them into food now. He continues to implement the plan step by step,

The weasel on the opposite side lost interest and left on its own. Unexpectedly, when the light spot reappeared, the weasel burst into his cave with smoke all over its body, howling, and plunged into the deepest shadow, clinging to the wall and wheezing.

Very powerful.

"Oh, it turns out it didn't make it back to its own cave, so it came to take refuge with me?" Alex glanced at it and found that its fur was burnt in many places. If it hadn't been running around underground all day long,

, the body is covered with mud, and the burns may be more serious. "The burns should be fine, but how much radiation have you received? Oh, I hope you are fine. Just stay there and hide there, and you can leave when the light spots pass."

The weasel couldn't understand Alex's words, and its actions relied entirely on instinct. It also understood that it was an intruder in this cave, so it stood upright, extended its claws, and bared its teeth from time to time, using this threatening posture to show that it did not

So annoying.

Alex ignored it and continued to work, so the weasel slowly relaxed. It turned around and licked its wounds, licking and screaming in pain, and then raised its eyes to look at Alex.

"You see what use I am, I don't know how to treat diseases. If Xiaoxiao is here, she must know how to take care of animals." Alex shook his head. Although he knew that the weasel could not understand what he was saying, he still said:

It chatted: "I don't have enough water, so I don't dare to share it with you. There is plenty of food, but I don't know if you can eat it. I have an evolution plug-in that can digest you, but if you eat energy bars, maybe you will

Die..."

The weasel lay motionless on the ground, looking at Alex with only two eyes. Maybe it was tired, or maybe its body was collapsing after being exposed to radiation. Alex shook his head and took off a cup lid from the mine cannon.

Shape parts, and then put some water circulated in the space suit inside, and place them in front of the weasel.

The weasel did not hide when Alex approached, so it probably had recognized the reality. When it saw the water in the lid of the cup, it crawled over without hesitation, buried its mouth and nose in it, and drank. Look.

It looked pitiful, so Alex picked out a piece the size of a melon seed from the energy bar and placed it next to the bottle cap. If this weasel was going to die, it should at least eat enough before it died.

After doing this, Alex continued to work on his work until he completed a "milestone" progress, which allowed him to take a rest for ten minutes. Looking back, the weasel was still alive, at least he was lying down with his body crossed.

It was more like resting than waiting to die. Half of the water was left, and half of the energy bar was left, and it was looking at Alex with vigour, and then looked distractedly at the sky outside.

"Already thinking about what will happen after the cluster radiation passes? It seems to be a smart little animal." Alex took a bite of the energy bar, put it under his tongue as usual, and then lay down to rest for a while. The weasel quickly hugged him

Bottle caps and food are retracted, showing a strong sense of defense.

Alex smiled and let it go. He closed his eyes and rested for ten minutes, then got up and continued working. When the light spot left and the outside environment became relatively safe, the weasel immediately ate the remaining food.

He drank all the water in the bottle cap, ran to Alex's feet, rubbed him with his tail, and then ran away as fast as he could.

"At least he knows how to be friendly." Alex's mood became lighter and his work efficiency also improved. The Weasel did not come back again, but his aircraft was completed four hours earlier than expected, which was enough to make him full of energy.

Sense of achievement.

This is a delta-wing aircraft with gliding function. The upper part is a flat titanium alloy wing, which provides part of the lift and serves as a protective baffle for concentrated radiation. Under the delta wing is the hiding place of Alex and various parts.

On the ground, Alex lay on a flat plate, protected by titanium alloy on all sides except the front and rear. The control components of the anti-gravity engine and mine cannon were on his left and right sides, and the energy obtained from the beam radiation through the filter maintained these components.

Its operation provides 90% lift, full power and a safety shield for the aircraft.

Alex predicts that its speed can reach at least 500 kilometers per hour. Since it can be continuously charged by solar energy, it can be used as long as the parts are not damaged. This aircraft was named "Small" by Alex

"Somersault Cloud", wait until it reaches the speed of 108,000 miles per second, and then change its name to "Somersault Cloud".

Before it was completed, the battery had been fully charged. Before the "killer star" came out, Alex decided to set off. There was no dark moon outside and the wind was high and the weather was cool. He could still see three stars when he walked out of the cave.

Stars hang in the sky, two yellow and one red. Fortunately, they are relatively far apart. They are like three small light spots on the horizon, only providing light without causing harm. With these three stars, outside

It is twenty times as bright as the full moon, and it is no different from daytime.

Since the problem of bearings and steel balls cannot be solved, the small somersault cloud has no wheels for the time being and can only be pushed by brute force. Under the standard gravity of the earth, it weighs half a ton. But this half ton is not a burden, but the best project.

, mechanical and electronic components, so Alex tried every means to bring it with him. Fortunately, after starting the anti-gravity engine, it will become very light and can float as long as there is wind, so it is not a burden.

Not everything that can fly is called a starship, but Alex can keep it secret and count the small somersault cloud as part of the starship database to control it as an external device. The mine cannon is the equipment of the composite evolved human.

, then the touchpad is standard, and there is no shortage of brain-controlled body connectors, so as long as Alex does not fall off the small somersault cloud, he can use his consciousness to control the flight and keep it in optimal operating condition.

.

"Don't fall" is the highest purpose of the little somersault cloud. Even if the power suddenly runs out, it can glide and slow down to land, so don't fall here refers to the controller Alex. He set six

There are three fixed binding points, and there are four more on the flat plate under the body. After installing all ten fixed points, he is basically connected to the small somersault cloud and is ready to take off.

In the "night", more than a dozen small glowing eyes appeared in front of Alex. They moved quickly close to the ground, raising one or two pairs from time to time, looking left and right to observe the surroundings - it turned out to be the weasel from before, taking his family with him.

A group of relatives came over. Alex didn’t think they were here to repay their kindness, but they probably took a fancy to the cave behind him. There are wet mountain walls in the cave, and the tongues of these little creatures should be able to replenish water from there.

Maybe that's why they like caves.

"Let's go, I'll leave the cave to you. I'm going to the river." Alex started the small somersault cloud, which was like feathers and floated into the sky with the breeze. The group of weasels stopped and raised their heads to look.

Looking at Alex, they didn't know what happened. But then they cheered and rushed into the cave.

There was a guy who was missing a lot of hair and did not rush in immediately. Instead, he looked up at the sky outside and shook his head at Alex. On the bright side, this might be his farewell. But Alex

It is not ruled out that it is wondering why the owner of the cave fled without a fight and allowed his family to take advantage of it.

As soon as he was distracted for a moment, the small somersault cloud began to tremble. Alex quickly adjusted the lift control surface and anti-gravity engine to make this dangerous tremor disappear. This was just a hand-built aircraft, and it had not been blown through a wind tunnel, or even

It can't even achieve left-right symmetry and balance. It can fly into the sky, firstly, it relies on the anti-gravity equipment to give it a strong lift, and secondly, Alex constantly adjusts the status of the aircraft according to the situation to make it relatively stable in dynamics.

When it first took off, the small somersault cloud relied on Alex's basic force thruster to gain forward speed, and then mainly relied on deflecting the direction of the anti-gravity engine to make it fall "forward and upward". Adding air resistance and passing resistance

The converted lift allows the aircraft to generate forward acceleration as a whole. The ideal state of a small somersault cloud is to reach a flight speed of 500 kilometers per hour without wind, but considering the constantly changing airflow, and the addition of Airri

Kesianpi's ability to withstand wind is actually not that fast.

Flying in the air, looking down at the sky and earth, it still feels extremely huge. Even if the rivers are turned into thin lines and the mountains are turned into folds, the end of the earth is still not visible in all directions. Alex tries not to think about this scene, because

It will cause more associations, especially the throbbing of the starship database, which is the most dangerous. Once he starts to think about what kind of starship to build next, he will be distracted and unable to focus on controlling the small somersault cloud, and he may crash at any time

.

After all, the anti-gravity engine is not a hydrogen balloon, and it will not always go straight up.

Riding a small somersault cloud, crossing ravines and deserts, avoiding the beasts that were fighting on the ground, Alex headed towards the river to check. Since the killer star regularly sweeps the sky, there will be no lions or tigers and other beasts here.

They are lizards, snakes and some insects that are more suitable for living underground. Alex saw a lizard the size of a calf tearing apart a python with a body as thick as a bowl. They were not satisfied with the previous "half-and-half split", maybe

They all have the idea of ​​killing each other and eating the food for themselves.

You can avoid these dangerous predators by flying in the air, but Alex has never seen any birds in the same group. He guessed that it may be able to fly and hide in underground caves. This requirement is too difficult for creatures.

, so birds like lions and tigers have been wiped out by killer stars. The creatures here seem to have never seen birds flying in the sky. They are not interested in the delta wings above their heads. Even if the shadow passes by, they will not

vigilance.

After flying over the mountains and the Gobi desert, Alex finally arrived above the river, where many animals had gathered to drink water. Alex saw hedgehogs, moles, groups of lizards and snakes, as well as porcupines and pangolins.

He became more and more certain that there was an underground vegetation system here, otherwise it would not be able to support so many diverse and large-scale animals. However, he was not sure whether the underground vegetation system was attached to a network of caves or in a deep canyon.

If he descends directly, Alex can only compete with the group below for water as an individual. If chaos occurs, those animals can completely crush the small somersault cloud. He continues to fly forward, leaving the gentle valley and arriving at the river.

At the sharp turn, there were far fewer animals, and there was a large enough open space for him to land.
