Starport City is the largest interstellar trading city on Makujung, and the huge interstellar transport ships, whether they are carrying people or transporting goods, all take off and land here.

Towering spaceship docking platforms are now busy, with many starships docking or landing here.

This is the first time Guo Yu has seen such a scene, Dawning City also has an interstellar port, but it would be good to have a few interstellar spaceships dock every year, and the scale is far less than that of Starport City.

In this moment, Guo Yu saw hundreds of interstellar ships taking off or landing, and even saw a huge transport ship three to five thousand meters long, rumbling to dock on a mooring platform at the top.

According to Guo Yu's understanding, because of the backwardness of science and technology, the interstellar trade of Makurong Star is not developed.

But even so, such a scene made Guo Yu can't help but imagine what kind of scene other prosperous life planets will be.

Li Xing piloted the C-class city spaceship and flew straight to a luxurious spaceship mooring platform in the eastern area of Starport City, where dozens of large and small spaceships had been docked at this time.

Around the mooring platform, there is a magnificent complex of buildings that surrounds the mooring platform.

The Makurong Star This year's several array exchange conference was held in this complex, or at the top of the complex.

The tops of many alloy buildings are connected to form a small city in the clouds, which is extremely prosperous, which is the landmark of Star Port City.

The city in the clouds is based on each alloy building of this complex, using special materials, linked together piece by piece, covering an area of more than 10,000 square kilometers.

Guo Yu and Eve, following Li Xing, crossed the hanging ladder located at a height of three thousand meters, and came to the city in the clouds.

"There are a large number of arrays engraved on the ground, which are copied and engraved by masters, such a complicated array system, at least a four-star array master can do it." Guo Yu immediately discovered the special features of this place.

The city in the clouds is located at an altitude of three thousand meters, this altitude was originally cold, but at this time, it is extremely warm.

Guo Yu understood that this was the change brought about by the number of arrays, and the entire city in the clouds carried out daily operations with the number of arrays as the core, and the imperial array isolated the cold in the sky, and at the same time resisted the bird-like energy beasts that often appeared in the sky of the Murong Star.

Those powerful bird-type energy beasts have extraordinary wisdom and dare not easily fly to the height of the four giant cities, but many bird-type energy beasts with low intelligence often break the precepts and attack the high altitude within the giant city.

The Imperial Array of the City in the Clouds has a very strong defensive force, and ordinary bird energy cannot be pierced at all, and it will be severely damaged due to impact.

"Bang! Boom! Boom! ”

As soon as he thought of this, Guo Yu saw that a series of three bird-like intermediate energy beasts with a body size of more than forty meters flew at extreme speed from a high altitude in the distance, targeting this city in the clouds, but when they were just a kilometer closer to here, they collided with an invisible defensive shield.

The huge impact force caused the three mid-level energy beasts to crack their bodies and fall to the ground three thousand meters below with blood.

"It's so strong, I'm afraid even high-level energy beasts can defend against it!" Guo Yu looked at the faintly lit white protective shield in the air thousands of meters above, and was secretly speechless.

"If the four giant cities are equipped with this defensive shield, how terrifying it should be, will the ordinary humans of the Curtain Star still be afraid of the energy beasts in the wilderness area?" Guo Yu muttered to himself in a low voice.

Every resident of Makurong Star has almost lived in the shadow of energy beasts outside the city since he was a child, and the information conveyed by his parents, or the information given by the people around him, revealed that the wilderness area was full of energy beasts, which was very ferocious.

When Guo Yu was a child, he worried many times, if one day the energy beasts in the wilderness area rioted and attacked the humans in the city, would the humans in that scene still survive?

The area of the four giant cities only occupies a small part of the Makurong Star, maybe less than one percent, and the rest are wilderness areas.

Now that he has grown up and become a martial artist again, Guo Yu also feels that his worries are superfluous, the four giant cities of Makurong Star have existed for thousands of years, and they are still intact, which shows that the high-level of Makurong Star has already taken a countermeasure to the energy beasts in the wilderness area, and he doesn't need to worry about it.

It's just that most of the current residents are still afraid of the energy beasts in the wilderness area.

If the four giant cities also have this kind of defense system with the imperial array as the core, it will definitely make the residents feel at ease.

"Haha, Guo Yu, your idea is very good, the same as what I thought when I was eighteen years old." A hearty laugh rang out, and an old man approached.

Guo Yu looked at this old man and immediately laughed, this person had gray hair and a big nose similar to that of Teacher Norton.

"Director Rohm, long time no see!" Guo Yu took the initiative to step forward and hugged the old man.

The old man is none other than Rohm, the director of the research institute of the Makurong branch of the TX Group.

As early as his freshman year of high school, Guo Yu met Rohm on a multi-array forum on the Star Network and became a New Year's friend.

This time, the two were naturally very happy.

More than half a year ago, Guo Yu was still a senior high school student about to graduate from Shuguang No. 1 Middle School, and at that time he had little hope of even being admitted to an ordinary martial arts academy, and wanted to step into society early and find a better job.

At that time, I went to the research institute of the Makurong branch of the TX Group to apply, and Director Rohm was very enthusiastic and hoped that Guo Yu would join, but in the end, because of the intervention of Hiss and his sons, Guo Yu's application failed, and there was a series of things later.

"Director Rohm, I'm smiling at you." Guo Yu is very modest in front of his old friends.

He also reacted, the idea just now was too naïve, the four giant cities, Dawn, Star Harbor, Falling Star, and Cold Snow, each with an area of nearly hundreds of millions of square kilometers, it is whimsical to want to put a cover on such a giant city!

First of all, the cost cannot be calculated, and it is estimated that with the wealth of the entire curtain star, such a defense system cannot be established.

Secondly, if you want to build such a huge number array system, I am afraid that the five-star number array division is not enough, and the six-star number array is also very hanging.

That's why Guo Yucai felt that his idea just now was too naïve.

"I'm also from your age, young people just have to think more about unrealistic things, whimsy is possible to create miracles, if you don't even dare to think about it, then what kind of progress is there to talk about, just like you kid, who would have thought that it only took you more than half a year to become a hot genius martial artist like installing a thruster!" It can be seen that Director Rohm is really full of emotion in his heart.

even ignored the old acquaintance Li Xing.

It wasn't until Li Xing took the initiative to greet him that he smiled and patted his head and talked to Li Xing about the past.

"Roma, let's make friends and friends, and when the exchange meeting begins, the two little guys next to me won't show mercy because you are a senior." Li Xing smiled proudly.
