Su Qin carefully circled around the big fireball or artificial sun, and found that the ball inside was almost concentric with the fireball. It seemed that the inside of the fireball was now weightless, otherwise it would be difficult to explain why such a regular sphere was formed.
But the surface of the sphere was not smooth, and it was constantly boiling and emitting bubbles like a boiling water pot, emitting some smoke, which reminded Su Qin of the molten steel in a steel-making furnace.
Su Qin was not sure if this fireball continued to burn like this. This asteroid, which obviously seemed to have an iron core, would turn into a bag of molten iron forever, or whether the mother would turn into debris and disappear under the erosion of high temperature and the inevitable presence of oxygen.
By the way, when Su Qin thought about this, the products of this fireball burning were probably carbon dioxide and water, right? Where did all this carbon dioxide and water go?
If it is still inside the fireball, will the pressure inside the fireball get higher and higher? Is it possible that one day the fireball will no longer receive sufficient fuel supply because the internal pressure is close to the atmospheric pressure outside the city's protective shield, and the fire will slowly decrease and eventually be extinguished?
But this should be a long time later. The size of this fireball is not small, and the spacecraft shield should be as resistant to pressure as the city shield. Su Qin is looking forward to what happens after that.
Maybe after the fireball is extinguished, the interior will slowly be filled with oxygen, and eventually the oxygen will rush out from the pipe, or a torch will form again outside the city shield.
Su Qin was thinking wildly while getting used to the wing suit. After circling the big fireball for a few times, he turned around and flew towards the dark cloud on the opposite side, ready to start sampling.
Now he can easily use the airflow to turn his body. Although he is still a little unfamiliar, he believes that he is not an amateur at flying, but it is a bit difficult to do other movements during high-speed flight.
Su Qin now bent one arm with difficulty and used the other arm to control the airflow to maintain balance. He turned sideways in the air and took out a metal gas sampling bottle from the chest pocket of the wing suit.
He also had to use his other hand to unscrew the cap of the gas sampling bottle. When doing this, he had to be careful about the change in aerodynamic shape caused by closing his arms, causing him to fall.
The wingsuit is definitely a good thing, and it also solves the problem that it is difficult for him to carry other equipment while wearing armor. However, today's mission is relatively simple, and he does not carry communication equipment.
Su Qin tried several times before finally opening the cap of the gas sampling bottle. It's not because of how difficult it is to open the bottle cap, but because of the action that can be completed in just one second.
Several times, he fell headlong to the ground due to the change in the center of lift caused by closing his arms. What was worse was that at this time, he was still kicking his legs to release his fighting spirit at his feet. As a result, he fell from the height he expected to lose for a while.
It turned into a high-speed dive towards the ground, and he was so panicked that he had to quickly stretch out his arms and bend his legs to change the direction of the fighting energy output, and recover his body from the dive.
He felt tremendous pressure from bending his legs, but fortunately the armor gave him a lot of help, allowing him to straighten his legs again after raising his head upwards.
The armor and this wingsuit flight suit are a perfect match. At his current speed, stretching out his limbs in the high-speed airflow is definitely a strenuous task. Controlling the flight with precise movements is extremely demanding on physical strength. high.
The physical requirements of wingsuit flying are mainly reflected here, but this is not a problem at all under the power-assisted system of this alien armor.
Su Qin tried several times in succession, and finally, while maintaining an upward angle of more than 30 degrees, he slowly retracted one hand, then the other, and finally succeeded in bringing his hands together and unscrewing the bottle cap. .
At this time, he had flown deep into the cloud, and the surroundings were dark, but Su Qin didn't care, as the armor had its own night vision effect.
Although there was nothing around him, at least he could see the big fireball, so he wouldn't get lost.
He was not worried that he would suddenly fly over his head and hit the protective shield in the core of the city, because he remembered that the scope of this dark cloud was not large, at least it did not spread to the edge of the protective shield.
He was going to take the sampling bottle and circle it a few times in the dark clouds, and then put the lid back on, which would probably complete the task.
Su Qin relaxed his left arm slightly, and the sudden strong airflow caused the angle between his left arm and his body to shrink from 90 degrees to nearly 60 degrees.
His body immediately sank to the left. Seizing this opportunity, he immediately kicked his right leg to increase the output of fighting energy on the right side. At the same time, he restored the position of his left arm. He immediately tilted his body and turned to the left, with a very fast movement. A large tilt angle hovered in the air.
In a wingsuit without a vertical tail, he could only turn like this. In fact, if there was a vertical tail, he didn't know how to operate it!
The surrounding clouds and mist are gray, and I don't know whether it is the original color or the background color of the sky, or whether there is some impurity and dust mixed into it.
Su Qin couldn't tell what the cloud was, but he felt it shouldn't be some poisonous gas.
Whether it is the protective shield at the core of the spacecraft or the protective shield at the core of the city, it is a new thing for people on earth, but it should be considered to have been tested for a long time on Salt Planet, and it is unlikely to let poisonous things in.
However, the atmosphere of Salter Star outside the protective shield does not seem to be a toxic gas, it is just flammable. Now it is a bit unclear. Anyway, let's take a sample for testing first.
After Su Qin completed his first circle in the air, he immediately began to find that the surrounding clouds and fog were not right. They seemed to be getting denser, and the big fireball outside the clouds and fog looked much dimmer.
He didn't think much about it for a moment, thinking that maybe he just hovered near a denser air mass. In this way, the samples collected should be more representative.
He immediately held the sampling bottle and crawled through the place with the worst visibility.
I don't know if it was a psychological effect, but Su Qin obviously felt that the atmosphere around him had become thicker, but no matter what happened, he believed that the armor on his body should be able to handle it, so he still did not turn away.
Su Qin kept moving forward until a spark flashed in front of his eyes, followed by a loud noise.
Is it really that kind of flammable gas? Something big is about to happen!
He didn't even have time to think, so he dived down, preparing to get out of the cloud first.
At this moment, many people on the ground were looking up at him.
There are no stars to see in the sky above Salt Planet. There is only a gray sky inside the protective shield. Everyone has long been tired of seeing the big fireball, otherwise the clouds and fog have been so eye-catching in the past two days.
