On the bus bound for Shendu Military Airport.

Liu Xiang lightly shook his arm at the person sitting next to him, and asked with a wink, "Why did you come with you?" Are you afraid that I will abduct your Xiaoyu away? ”

"What's the matter, I just want to go to the plane to try, I've recently increased a lot of actual combat experience, just go outside the plane to increase the experience of killing monsters!" Cai Lincheng peeked at Lei Xiaoyu, who was a few seats away from him, and his face was slightly red.

Liu Xiang knew that Cai Lincheng, a big otaku, was too rare Lei Xiaoyu, although he said something to increase his experience in killing monsters, in fact, he couldn't do without it, and his performance on weekdays was also, he would go wherever Lei Xiaoyu went, and if he had nothing to do, he would go to Lei Xiaoyu to learn from him, and he would increase his actual combat experience.

But don't really say it, Cai Lincheng and Lei Xiaoyu really found the right person, the first Lei Xiaoyu has rich experience in actual combat, and the second Lei Xiaoyu is really ruthless! Cai Lincheng lacks these two things, after two months of fighting, Cai Lincheng's junior martial arts realm is not stable, and the actual combat experience has also been raised, coupled with his super family swordsmanship, Lei Xiaoyu is faintly a little behind.

Before Liu Xiang advanced, he really didn't dare to say that he would win.

As for Lei Xiaoyu, I heard Cai Lincheng say that the threshold of the great martial artist has been almost grinded, and I am afraid that it will not be long before he can advance, and when Lei Xiaoyu advances to the junior great martial artist, coupled with his long-term physique and perfect combat skills that far surpass others by eating high-grade spiritual flesh, Cai Lincheng is still beaten.

"You said you've been soaking in the big dye vat of the university for two months, why is your skin really thin?" Liu Xiang said jokingly.

Cai Lincheng's complexion changed suddenly, glanced at Liu Xiang and muttered: "The exercise of the skin is a part, and the most important thing is to rely on nature!" ”

Liu Xiang raised his eyebrows, understanding that Cai Lincheng was saying that he was naturally cheeky in disguise, and couldn't help laughing: "Oh, that's good!" There is growth! ”

"The one who is close to the ink is black!" Cai Lincheng underestimated again.

Liu Xiang couldn't hold back any longer, and laughed, and the laughter attracted other students to look at them involuntarily, and Lei Xiaoyu was also one of them.

Liu Xiang raised his hand and beckoned to Lei Xiaoyu, pointed to the empty seat on the opposite side of the aisle and said, "My dear, come and ask you something." ”

The corners of Lei Xiaoyu's eyes twitched a few times, and he walked over angrily, Liu Xiang didn't have a positive mouth all day long, Lei Xiaoyu was used to it! Didn't you see that Cai Lincheng couldn't afford to be jealous anymore?

"What?" Lei Xiaoyu came over and sat down, and asked angrily.

Liu Xiang restrained his smile and said with a serious expression: "What does the high plane look like?" ”

Lei Xiaoyu lowered his head and thought for a moment, raised his eyes and said, "What do you say?" Our human cognition of higher planes is as ignorant as the cognition of the earth when human beings first walked upright in ancient times.

Even if we have been rooted in the high plane for 18 years, every day new information is discovered, whether it is plants or animals or whatever, we really have a range of only a few thousand kilometers, and the places we have set foot on are only 10,000 miles, this range is huge enough on the earth, but for the high plane, it may only be the tip of the iceberg.

One thing is certain, the high plane is not a planet, it really responds to the ancient people's saying that the sky is round!

The earth is flat, there is no radian, or there is an arc, but it is too small to measure!

There are spring, summer and autumn on the high plane, but there is no winter, there is night and day, but there is no sun, moon and stars! As for why? No one can explain it.

Night corresponds to day clearly, time is equal, calculated with time on the earth, 24 hours of day, 24 hours of night. As soon as the time comes, the sky will change in an instant!

However, although there is no sun, moon and stars, there is still a faint green light in the whole sky in the dark night, so that you can't reach out and lose sight of your fingers.

And the most important point, in the high plane, whether it is to exert spiritual energy or physical action, it will be twelve times more difficult, just like the entire space is twelve times thicker, this is not because gravity has increased by twelve times, if it is gravity, a person like me who was born on the high plane, I am afraid that even if he can adapt to the environment of the high plane, he will be crushed to death by his own weight when he is born.

This is also the direct reason why the martial artist can't fly, the consumption is too great, the martial artist can at most perform short-distance low-altitude gliding, and the real fast action still depends on the legs.

The most dangerous thing in the higher planes is not the endless level of monsters, but the strange plants, insects and environment, but after all, humans have set foot in eighteen years, and most of the dangerous species in the control area, that is, the safe zone, have been mastered, and the danger is still a larger range of dangerous places outside the safe zone.

Outside of the plane, all your actions must follow my instructions, and do not touch the unknown.

Another point, don't break away from the team, there is no east, west, north and south in the high plane, all the knowledge on the earth that can identify the direction will be useless, and when you enter the high plane, all the communication signals will fail, only the fixed lines laid in the safety zone are useful, so once you enter the dangerous place, if you don't have rich experience, it is difficult to get it back in the case of leaving the team, and it is even more difficult to return to the safe zone alive. ”

Liu Xiang and Cai Lincheng looked at each other for a moment, and nodded at the same time.

"We get it!"

Lei Xiaoyu continued to introduce Liu Xiang and the others to some common but dangerous things.

Liu Xiang also had a general understanding of the situation outside the plane through Lei Xiaoyu's description.

The so-called security zone is just centered on the plane gate, with an area of hundreds of thousands of square kilometers, which is less than one-tenth of the area of Huaguo.

This is the area that took 18 years for humans to fully control, and when converted into a square, it is only 700 kilometers long.

The danger area mentioned by Lei Xiaoyu is large, converted into a square, that is, the side length is four or five thousand kilometers, which is almost the size of several Chinese countries.

This is an area that humans have explored in more detail, and humans have often set foot in.

But this is still only the tip of the iceberg, when human beings first entered the high plane, there were grandmasters who flew more than 100,000 miles in one direction, which is equivalent to sparing the earth three or four times, but still did not find any special landforms, or special environments. The natural environment along the route has remained largely unchanged.

When the Grandmaster was about to continue moving forward, he suddenly felt that there would be great danger of going any further, so he returned straight to the same path out of caution. Fortunately, I didn't encounter any grandmaster-level monsters along the way back and forth, and I returned to the plane gate safely.

Unfortunately, the Grandmasters can't resist the temptation of the unknown, and more than half of the world's Grandmasters have become cats killed by curiosity.

This is the scene where the grandmasters of all countries in the world join forces to explore, and there has been no news since then.

Therefore, people call it an unknown place thousands of miles beyond the gate of the plane.

Although the advance army is looking for traces of the missing grandmaster, in fact, it is only to probe information within tens of thousands of miles, and people have long lost hope for those grandmasters and students.

Liu Xiang listened carefully to Lei Xiaoyu's explanation of the basic knowledge, and also carefully kept this knowledge in mind.

He didn't want to become a dead cat for the first time when he entered the high plane!

The bus came to the Shendu Military Airport in Lei Xiaoyu's leisurely narration, and after a series of identity information confirmation, Liu Xiang followed everyone on a strange-shaped psionic plane.

The plane was huge, and the hundreds of students were only half full, and as the plane started, a strong feeling of pushing back hit.

Liu Xiang, who had made a psionic plane, was surprised to find that the speed of this military aircraft may be beyond his cognition.

Sure enough, when the plane rose into the sky, it accelerated violently, and a deafening roar suddenly sounded.

Sonic boom!

This psionic military airliner has surpassed the speed of sound!

As Liu Xiang expected, the plane flew straight to the north, Liu Xiang knew in his previous life that the plane gate was on the Arctic continent, although it was not opened at the North Pole, but for people, it was already the northernmost part.

This military psionic airliner was really fast enough, and it only took more than three hours to reach the Arctic continent.

Looking at the white world outside the window, Liu Xiang couldn't help but feel nervous.

Is it finally going to the high plane?

At this moment, Liu Xiang's mind underwent a huge change, when he just returned from reincarnation, Liu Xiang wanted to become a martial artist so that he could protect his family when the end of the world came.

And now, he is about to cross the gate of the plane and go to the high plane, does this mean that he has begun to defend and attack?

Liu Xiang shook his head and threw away the messy thoughts.

The plane finally began to land, and Liu Xiang looked down through the window, where a large military base sat below, like a huge city.

The flags of the 33 countries that exist on the planet are planted on both sides of the runway.

Liu Xiang's sharp eyes found that the red flag of Huaguo seemed to be in the first place!

When the plane finally landed, Liu Xiang couldn't hold back his excitement, and was the first to rush to the hatch and the first to jump off the plane.

A chill hit, with Liu Xiang's physique, he couldn't help but feel a little cold in his nose, of course, this is the cold wind in the Arctic, the biggest effect that Liu Xiang can bring to Liu Xiang, Liu Xiang is now just looking at his physique, he is already a junior senior martial artist, not to mention that he is still wearing a martial arts uniform, even if he is buried in the ice shell of the Arctic shirtless, he will not be able to hurt him in the slightest.

After landing, Liu Xiang raised his eyes and looked in one direction and was stunned.

Is this the Plane Gate?

It's even more shocking than the pictures in the book!

A pitch-black void with a width of a thousand meters and a height of several hundred meters rose into the sky, attracting all of Liu Xiang's mind.

"Shocked, huh?" Lei Xiaoyu and Cai Lincheng walked behind Liu Xiang.

"Hmm." Liu Xiang nodded, and then said with a big brain: "You say, if you pull all the steel from all over the world over, and then build a solid steel giant mountain around the light curtain, can you block the plane gate?" ”

"Can't be blocked, do you think only you can think of it? Although it didn't pull all the steel from all over the world, a giant mountain of reinforced concrete had already been built! It's a pity that it's useless, once the stability of the plane gate fluctuates, it will suck anything dozens of miles in front of the light curtain out of the surface, even if it is built to a thickness of hundreds of miles, it still can't stop the minions of high-level monsters, and it can't be built dozens of kilometers high! And can you imagine how much it weighs? I'm afraid that even if it is really built with the power of the whole world, do you know how heavy it is? The ground couldn't hold up in the first place. A breakthrough is also a matter of time. Lei Xiaoyu shook his head and said.

"Let's keep up!" Liu Xiang let out a long breath and beckoned the two of them to follow Li Mengqiu's teachers and students who were walking towards the gate of the plane.
