"Around?" everyone blinked, feeling a sudden burst in their hearts.

Lieyang pointed to the map: "We are on the southeast side of Ningguo, and the island and main defenses of Ningguo are concentrated on the west side of Gulang Island. What if we followed the southern tip of the sea and went around to the east side of Gulang Island?"

Although the Ningguo fleet is powerful, it is limited in number, and it is already the upper limit of the fleet to be able to build a maritime blockade line that stretches thousands of miles across the three island chains.

Then the east of Gulang City must be empty!

Lu Yu shook his head: "Lieyang, do you know that the north and south poles of the Stardust Continent are located?"

Lieyang replied, "After the northern snowfield, there is the Endless Ice Field, the extreme north of the continent, which is completely frozen. And Antarctica ......"

His gaze penetrated the jungle and looked at the sea to the south: "It is said to be a ghostly ghost that belongs to the Stardust Continent, and any soul that comes close will be strongly sucked. Once the spirit is out of the body, it means death. ”

The two poles of the Stardust Continent, of course, he knows it well.

Lu Yu looked at him with his eyebrows and asked suspiciously, "Then ...... How?"

Lieyang smiled slightly, waved his finger lightly, and led out the Dao Separation Fire Spirit, adding a three-dimensional outline on the plane map outlined by the Wind Spirit: "We, go around from the sky!"

"Huh?" everyone looked at each other.

Bang Cheng questioned: "Above the Cave Heaven Domain, there is also a difference in the flight altitude of cultivators of different levels - of course, cultivators can also gain stronger flying ability by strengthening the Spirit Eye Heavenly Feather. If that's the case, my starlight wings can only take me up two thousand meters......"

It's not even as good as the better-performing snow wing.

Bang Cheng didn't think that the height of two thousand meters was safe enough, he shook his head and said, "If Xiahou Zhushen is fully guarded, his soul power will cover a radius of more than fifty miles!"

That is, 25,000 kilometers!

Bang Cheng smiled bitterly: "General Lie, if we want to steal from the sky, we must enter the air at an altitude of 30,000 meters!"

Hearing this number, Lieyang was also stunned.

He muttered in his heart: Hei Tian can ignore the flight restrictions of Tianzhu Mountain and drag the Extreme Realm team to an altitude of 30,000 meters, there should be no problem?

"I'll try it tonight. Lie Yang took a deep breath, his eyes revealing a little excitement, "Who wants to be with me!"

The scorching sun has a black sky protector and can survive in a harsh environment, but the team members may not.

"To be on the safe side—" Lu Yu also knew that this was the quickest way, and she said seriously, "Let's test together—and, dragging the nine of us, how far can you fly?"

This place is more than 500 miles away from Gulang Island, the cost of flying is extremely high, and the state of the scorching sun is obvious to all, can he insist on flying the whole way?

"Try it. ”

——

That night, a large scale of lights was lit up at one end of the five islands, and upon closer inspection, it was discovered that there were hundreds of pirates living there.

The building was like an ordinary island village.

"Luckily it's dark here, otherwise it wouldn't be easy to fly at night. In the distance, Yue Zheng secretly looked in the forest, and only when he heard the call of the scorching sun did he retreat.

In the woodland, where it was a little fuller, the sun had spread its wings. The black bone wings have clear lines, which makes people inevitably wonder: the wings of the sun are not spiritual eye feathers, but the black wings don't even have a single hair, how can they fly?

Lieyang didn't bother to care about these questions, so everyone tied safety ropes of different lengths, and then divided them into two parts, left and right.

On the left are Lu Yu, Lu Wei, Qin Shuang, Gu Xue, and Bang Cheng.

On the right are Lu Qi, Bai Xian'er, Yu Fei, and Yue Zheng.

Although the number of people on both sides is different, the weight is comparable.

Blazing Sun tied a total of nine ropes to the left and right parts, all of which were tied to the pre-tied rope loops on his shoulders.

"Ready!" Lieyang exhaled lightly, and after checking his eyes with the nine companions, he let out a shallow sigh, "Get up!"

The black wing behind him didn't make any obvious movements, but Lieyang's body rose smoothly into the air, dragging the left and right groups of people off the ground and quickly swept into the air!

As the altitude climbs, the scene of the black sea is like a huge picture, unfolding in front of everyone's eyes. The dotted islands are shining brightly.

The Black Sea City at the core was transparent and bright, and the light shot straight into the dark night sky.

"Wow!" Gu Xue exclaimed, "If you fly so high in Chenguo, the scenery you can see must be even more beautiful......, right?"

However, before she finished speaking, Gu Xue's body suddenly became agitated, and she felt an extremely cold breath!

The surrounding airflow is also relatively disordered, like a cold blade, attacking the rising crowd!

"Scorching sun, the temperature is too low, the rope is freezing!" Lu Yu reminded loudly, "If it goes on like this, the rope will not be able to hold it!"

At this moment, the cold that was eroding people's hearts eased slightly, and the invisible ice patterns spread out in the team, Qin Shuang spoke: "I will set up a formation to protect the rope, and everyone will operate their own meridian energy to resist the cold!"

"Okay!" Gu Xue gritted her teeth, her cultivation in the team was the lowest, and under the harsh natural conditions, she suffered the most.

In just three or two breaths, the little girl's forehead and eyebrows were covered with a layer of light frost.

She gritted her teeth and insisted, even though there was a piercing pain in the palm of her hand touching the rope, there was no gnawing sound.

"Now the height is 10,000 meters!" Lieyang's five senses were more acute, of course, he knew that everyone was uncomfortable, and his face and hands were also frozen.

Bang Cheng said: "It's too high, everyone's spirit seeds have been suppressed by the laws of heaven and earth, I'm afraid it won't last long!"

As a super powerhouse in the Cave Heaven Domain, Bang Cheng still felt that it was very difficult to overcome, and the pain of Lu Yu and the others could be imagined.

"Will it be suppressed?" Lieyang frowned, he didn't expect this bold plan to die so abruptly......

If the spirit seed is not suppressed by the laws of heaven and earth, as long as it keeps running, it can maintain its body temperature. Sticking to your destination isn't much of a problem.

However, without the protection of the spirit seed, it is almost impossible for everyone to succeed in resisting the harsh environment of the high altitude with their bodies alone.

Lieyang saw Xue'er's pretty eyes closed, and her hands clutched the rope, and her heart suddenly hurt. Just as he wanted to end the test, Feng Lao's voice suddenly came: "Stinky boy, speed up!"

"But ......" Lie Yang doubted Feng Lao's words for the first time, "the higher you go, the colder it seems to be, everyone will freeze to death!"

"Lao Tzu is from above, what is the situation above, Lao Tzu doesn't know better than you?" Feng Lao snorted extremely dissatisfied, "Hurry up and rush upward, after the altitude exceeds 12,000 meters, the temperature will slowly rise!

“......”

A trace of heat burst out from between the teeth of the scorching sun, he was originally distressed by Gu Xue and worried about everyone's situation, but in the face of a choice, he would still believe in the master!

"Everyone hold on, the situation above will be a little better!" Lieyang pretended to be relaxed with encouragement, and immediately tried his best to open a large area of black sky barrier and protect everyone in it.

Raise your head and soar to the limit of the sky!

"Lieyang ......" Bang Cheng was shocked when he noticed Lieyang's choice, but the matter had come to this point, he had no choice! Hurriedly said, "I also use the Spirit of Starlight to protect everyone, you just have to rush up! Even if the rope is broken, I will guarantee everyone's safety!"

"Okay!" Lieyang shouted hard, looked down and scanned, and found that except for Bang Cheng, the other team members were all frowning and gritting their teeth to insist.

Even with the protection of the Black Sky Barrier and the Starlight Spirit, the altitude of more than 10,000 meters was still too harsh for the cultivators under the Cave Heaven Domain.

It is equivalent to throwing an ordinary person into boiling water, and the torment can be imagined.

"12,000 meters!" The scorching sun sprinted with all his might, and his ability to fly in the dark sky was not reduced by the increase in altitude. On the contrary, it gave the sun a kind of pleasure of galloping and soaring.

How fast at low altitude and at high altitude it seems...... Faster?

"Master, what is the principle of the black wings?" Lieyang was very curious, flying his wings at will was simply the supreme magic weapon that human beings dreamed of!

Feng Lao didn't bother to explain, and snorted: "Hurry up, you will leave the troposphere immediately - enter the stratosphere, and you will be safe." ”

The troposphere is located in the lowest layer of the atmosphere, where about three-quarters of the air and more than ninety percent of the water vapor mass are concentrated. Its lower boundary is connected to the ground, and the height of the upper boundary varies with geographical latitude and seasons.

In the Stardust Continent, the average altitude is 12,000 meters.

The troposphere extends from the surface of the continents to the top of the troposphere, the beginning of the stratosphere.

In the far north, a boundary layer with an average thickness of two kilometres is formed, as friction on the surface affects air flow. The formation of this layer varies mainly depending on the topography and is separated from the rest of the troposphere by the countertroposphere.

In the troposphere, the closer you get to the upper limit, the cooler it gets, so the Arctic team is almost frozen.

As soon as you break through the upper limit of the troposphere and reach the stratosphere, the extremely low temperature will increase with altitude. If you think about it, if the scorching sun can really take you to an altitude of 30,000 meters, you may still feel that the climate is "pleasant".

"Twenty thousand meters!" the sun roared, everyone could clearly feel the temperature rising, and the frozen rope was much easier.

But......

Bai Xian'er said loudly: "Childe, I'm ...... I'm a little out of breath......"

And this problem, Lieyang is also aware of it.

After entering the stratosphere, the air is extremely thin and cannot meet the breathing needs of the human body at all!

He shouted softly: "Everyone turns to breathe, don't faint!"

Fainting from lack of oxygen at tens of thousands of meters in the air is even more dangerous than suffocating in the sea water - fortunately, the sea water will make people float, and falling from here is only a dead end!

"Internal breath?" Lu Yu's slightly frozen body gradually warmed up, and when he heard Lieyang's command, he suddenly felt a little bad, and hurriedly said, "Lieyang, everyone's internal breath doesn't last long enough, Xue'er can only last for about ten minutes, how far can you fly?"

If you don't go fast enough to fly far, you'll have to descend into the troposphere when you're running out of internal breath.

That level of low temperature can kill the team members at any time!

"I ......" Lie Yang also realized the situation, and his breath was short, "I'll do my best!"
