Li Feng kept flying towards the sky, leaving behind a group of stunned people. Everyone didn't know what Li Feng's intention was, but everyone believed in Li Feng unconditionally. The team members knew that the captain must have their own reasons for doing this, and the indigenous people put all the hope of life on the gods in their eyes.

Li Feng, who kept flying towards the sky, was still feeling quite vain. The previous flight reached a height of 15,000 meters, but in fact he had reached his limit. If he gritted his teeth and worked hard, it would not be a problem to go up one or two thousand meters. But if it was higher, the thickness of the cloud was completely inestimable, and he could only see something as huge as a cover of the sky and the sun through the clouds.

This side mission is obviously very complicated, and it requires the splicing of various parts of the combat uniform within a limited time. If nothing unexpected happens, you need to find energy. After all, the strongest person in the team will fly into the sky in clothes and pour water from the sky. After flying to the sky, whether there is any test waiting is still waiting, these are also uncertain.

The mission lasts only ten days in total. It is absolutely difficult to spare time to do this side mission when the kill is guaranteed to be completed. However, the more rare the task is, the more interested Li Feng is, because this reward must be an extremely generous existence.

In the blink of an eye, as Li Feng continued to rise, he had already reached a height of ten thousand meters. Looking up, the clouds were above his head, and the dark unknown object that gave people a kind of mountain pressing down on it was still there.

"Really, what is the clouds designed by this world that are so high?"

Li Feng said the complaints to relieve his nervousness. According to the information he had known in the past, low clouds would exist thousands of meters. But in this world, clouds exist at a height of ten thousand meters, which is really difficult for people to do.

It is obvious that the system is making things difficult for people here. It must be considered that some people can fly, which eliminates the possibility of skipping classes without following the process. However, the system did not do this very well, and gave everyone some methods beyond the process and did not impose completely deadly constraints. However, the difficulty of not following the process is really a bit great.

This is not wrong with Li Feng, who likes to compare through game thinking. The completely rigid bundled process is definitely not a good game. It is a good game with other open possibilities for completing tasks. As the Light of Trial said when the first time the trial came, it is a playground between life and death. For Li Feng, calmly use this as his favorite game to play, and turn the trial between life and death into his own specialty game field.

The surrounding temperature has dropped sharply, and there is no heat below at all, but the same desolation as the top of the mountain. However, the temperature at this height should be quite cold, and it is still due to the severe high temperature emitted from the ground below that it has also been affected to a certain extent. Li Feng slightly eased his breath and continued to fly upwards.

The more you go up, the colder you feel. If it weren't for Li Feng but an ordinary person, you might have frozen into a lump of ice. Perhaps this extremely cold temperature is envied by the people below now. However, the human body has a suitable temperature, and there will be big problems whether it is cold or hot. I once saw people who took off planes to ride on their own, but when the plane landed, everyone could only find that the person was frozen into a lump of ice. What's more, the current altitude is much higher than that of ordinary passenger planes, so the temperature here is just that most ordinary people are discouraged.

Why is the material of this combat uniform not resistant to high temperatures but cold, and has a certain absorption effect on severe cold. The surrounding temperature is the reason.

However, this temperature does not pose any threat to Li Feng. For Li Feng, the temperature is just cool. You will feel cold when you move up, but it is still not a big problem. The biggest problem for Li Feng now is that he is afraid that he cannot reach the flight altitude in terms of his own ability.

Soon, Li Feng had reached a height of 15,000 meters, which was the highest distance he had reached last time. At this moment, Li Feng had already penetrated into the clouds. The clouds were so thick that Li Feng could not imagine how far there was to cross the clouds above.

Gripping my teeth, I said nothing now, and I will only know if I have tried it. I do have a bottle of potion that can briefly and significantly improve all abilities, including mental power, etc. It is fine to drink that bottle of potion, which can increase the flight altitude at least to 20,000 meters. Although I don’t know how high it is, it should not exceed 20,000 meters. Because that combat uniform will definitely not make people fly up to 20,000 meters. Through last night’s research, Li Feng at least affirmed this point.

But Li Feng would not choose to use that bottle of potion. To put it bluntly, he thought that the current situation was not enough to let him use that. The potion was the last to use it, and it was the last method in despair. It would never be possible to use it for a long time on such an unnecessary task. Therefore, he had just had this idea, and Li Feng cheered up and threw it away and continued to fly upwards. If it really doesn't work, he can choose to give up, but he must not easily hand over this last method of fighting for life, especially after the effect of the medicine, there will be a long period of weakness. This is weak at a high altitude, not a joke.

I gritted my teeth and persevered, and flew upwards to a height of 1,000 meters. I saw the darkness in front of me getting closer and closer, but it seemed that I was always at the closest distance and could never be touched.

It was even colder here, but the temperature would not make Li Feng feel cold at all. Instead, his face was red and even sweat appeared, which seemed very uncomfortable. Because now, Li Feng was in a very dangerous state due to various reasons.

The more you fly upward, the thinner the air becomes. It is also related to gravity, flight speed, etc., which will cause disadvantages to flight in many cases. It can be said that every time you fly upward for a distance, this pain will increase several times. Only after you become stronger can you use your strength to serve most of these factors and thus reach a higher flight altitude.

In the blue stars, even the winged races, their flight altitude is generally only 100 meters, and the highest is only 2,000 meters, and rarely fly at an altitude of more than three or four thousand meters. No matter how high altitude you fly, you basically use airships and other means of transportation. Flying as high as Li Feng, like the one who lives on his body, can be said to be a feat.

Li Feng kept gritting his teeth. Only in this way could he relieve some of the pain. Continue to move upward and continue to move upward.

"If the last 1,000 meters is really not possible, we can only withdraw."

Feeling the limit of his body, Li Feng didn't want to die here. It is estimated that 1,000 meters up is his ultimate limit. No matter how high he is, he will faint. At this height, anyone who falls will definitely be crushed to pieces.

Enduring all the pain, every time you fly upwards for 100 meters, you will feel an extra layer of pain.

500.600.700

Li Feng kept calculating the distance in his heart and feeling his limit height.

800…out!!!

Just as we were flying another eight hundred meters, we finally broke through the thick clouds and reached above the clouds.

And the dark thing on the clouds finally appeared in front of Li Feng.
Chapter completed!
