Five thousand years ago, before the catastrophe, the location of Flying Bear City was a huge super city, and Flying Bear City was built on the ruins of the city, and the ruins are the most important resource of Flying Bear City.

Therefore, the layout of Flying Bear City is also a piece of east and west, and urban areas have been established around the ruins with the most intensive resources in the past, and the periphery is defended by high walls.

Between the urban areas, the distance is far away, many places are clogged with ruins, the roads are rugged, and the traffic is inconvenient.

The Zhenqi rail train erected in the sky has become the best means of transportation, and the vast majority of ordinary people will take the Zhenqi rail train every day to travel between home, school, and factory.

As soon as Wu Ma Yan and Li Yao got on the train, a conductor came up to check the ticket, Wu Ma Yan raised his chest high and said loudly: "I am a Qi Refiner!" ”

The conductor suddenly changed his attitude, and said respectfully: "Please go to the exclusive carriage of the Qi Refiner in front, this ......"

Wu Ma Yan said again: "He is my friend and a qi refiner, but he was injured in hunting recently, so I'll help him vent later." ”

Under the leadership of the conductor, the two of them passed through the two carriages all the way, and when the passengers saw the direction they were heading, they knew that they were all qi refiners, and they all showed a look of worship and respect, as if they were some kind of big heroes and big people, and Li Yao was a little embarrassed to see them.

Compared with ordinary carriages, the exclusive carriage for qi refiners is not necessarily very luxurious and exquisite, but there is a large iron frame at one end of the carriage, on which are placed a lot of black and swarthy metal balls, each ball is slightly larger than Li Yao's palm, and the surface is full of holes and valves, which reminds Li Yao of the ultra-high compression wafer reactor on the crystal armor, but it is more rugged and primitive.

Wu Ma Yan naturally lifted two metal balls from the shelf and thought about it. mentioned one more, and took Li Yao to find an empty seat and sit down.

Li Yao looked over and saw that there were several Qi Refiners sitting in the other booths, and each Qi Refiner had two or three metal balls in front of him.

Just now, Wu Mayan also said to the conductor that he wanted to help him get angry, but I don't know what it means.

"Whew!"

The train roared. Not only the front of the True Qi locomotive, but also under each carriage, a large amount of white smoke spewed out, and the carriage seemed to be shrouded in a haze, rumbling forward, gradually rising to a height of twenty or thirty meters above the ground.

The scenery outside the window changed, Li Yao admired it with great interest, and saw five steel towers hundreds of meters high standing not far away, and in the middle of each tower was a huge spiral iron pipe. Pierced deep into the ground.

At the top of the tower, more than a dozen white smoke shot out, like a roaring dragon, causing the iron pipe to continue to drill into the ground.

Wu Ma Yan followed his gaze and explained with a smile: "Uncle Sand Scorpion, this is the 'True Qi Water Dragon' in our Flying Bear City, which is specially used to drill groundwater!" ”

"Everything is good in this area of Flying Bear City, there are a lot of hedron veins. It's all in the open pit, and it's very convenient to mine. It's just a lack of water! ”

"Since the establishment of these True Qi Water Dragons, they can drill deep water sources hundreds of meters underground, which are clean and delicious, and the problem of water shortage has been completely solved, and the population of Flying Bear City has gradually increased. It has become one of the largest cities in the six parts of Cheorwon! ”

Li Yao watched intently.

When he was in the Tianyuan Realm and the Flying Star Realm, he had also seen a lot of earth-drilling magic weapons powered by spar spiritual energy.

But it was the first time I had seen a large-scale magic weapon driven by pure true qi, and it could go hundreds of meters deep underground!

The wisdom of human beings really shocked him. The flame of civilization is like a tenacious weed, no matter how harsh the environment, it can find a new way to stubbornly drill through the cracks in the stone and emerge!

While he was secretly admiring, there were several loud roars in the sky.

Li Yao stretched his head out of the car window slightly, but saw several huge gray-white airbags slowly passing by in the sky, and there was an iron-gray cabin hanging under the airbags.

On both sides of the cabin, there are two wide wings stretched out, and behind the two wings and the cabin, there are a total of four pairs of propellers, which rotate rapidly under the drive of true qi, driving the airbags to fly slowly, dragging out white traces and slowly spreading out.

"This is the True Qi Airship, which is used to communicate between Flying Bear City and various towns in the tribe!"

"The people who control the airship are all masters of the Qi Refiners, and their control of True Qi has reached a very subtle level."

"They can use a special technique to make their true qi extremely thin, even much lighter than air!"

"Pour this 'thin true qi' into the huge skin bag, you can float in the air, and then use the true qi to drive the propeller, and you can fly freely!"

"This is a true qi magic weapon that has only been invented in the last three hundred years, and with the true qi airship, the connection between Flying Bear City and many towns is even closer."

"It's just that in the sky, there are also a lot of flying demon beasts, which often attack the True Qi Airship, so on the True Qi Airship, there will be a lot of guards, called the 'Flying Bear Army', that is one of the most popular professions in the Wild Bear Tribe, my previous dream was to become a Flying Bear Army!"

Wu Mayan held his head high and said with great interest.

As he spoke, he took a metal ball, first opened a valve on it, and pressed his hands on the metal ball, ten fingers facing the ten holes, and palms facing the other six holes, a total of sixteen holes were tightly blocked by him.

"Drink!"

The young man's eyes widened, and he suddenly let out a loud shout, and his true qi was agitated, and he burst out with the powerful strength of the twelve layers of the qi refining period!

Li Yao felt that the true qi around his body was wrapped around his arms in a spiral form, and then poured into his hands through his arms, and from his hands he continued to blast into the hollow metal ball!

The metal ball emits a faint "hiss" sound.

Above the metal ball, there was a brass pressure gauge with a red pointer on it, and as Wu Ma Yan's true qi continued to pour in, the red pointer also continued to sway, constantly rising from the left side to the right side.

There is a circle scale on the pressure gauge, which goes from zero to a hundred.

When the pointer reaches 60, it is a little immobile, no matter how Wu Mayan is red-faced, the pointer trembles, but it is no longer raised.

Wu Ma Yan let go of his hands stupidly, tightened the valve on one side again, and muttered, "Another intermediate real balloon!" ”

He took a moment's breath, moved his hands and feet, grabbed the second metal ball, took a deep breath, and said to himself, "This time we must break through 65%!" ”

Seeing Li Yao looking at him in bewilderment, Wu Ma Yan smiled and said, "Uncle Sand Scorpion, this thing is called 'True Balloon', and it is the most important magic weapon of our Tieyuan people!" ”

"You see, we Tieyuan people can be said to be a true qi civilization, whether it is flying in the sky, running on the ground, whether it is fighting with demon beasts, fighting against the heavenly tribulation, or pumping water, farming and building houses, we must use true qi."

"However, only our Qi Refiners can produce True Qi in their bodies, even if ordinary people become powerful martial artists, they don't have True Qi in their bodies, so aren't ordinary people unable to control the True Qi magic weapon?"

"So, a long, long time ago, there was a great Qi Refiner who invented the magic weapon of 'True Balloon', which is like a very strong pressure cooker, which can store a lot of high-pressure True Qi!"

"You see, we store the True Qi in the True Balloon, and then give the True Balloon to ordinary people, and ordinary people use it as a source of power, wouldn't it be possible to use some simple True Qi magic weapons?"

Wu Ma Yan said with a smile: "So, just now you saw that we didn't have to buy tickets when we got on the bus, this is not the privilege of Qi Refiners, but we Qi Refiners, we can't use money, but we have to use True Qi to buy tickets!" ”

"If a Qi Refiner wants to take the True Qi Train, he needs to fill at least one low-level True Balloon."

"Oh, the true balloon is divided into three levels, high, medium and low, it depends on how much true qi you pour into it, the more true qi you fill, the greater the pressure inside, and the more difficult it is to fill it in, like now, I only have the strength of the twelfth level of the qi refining period, and I can only fill the true balloon to about 60%, so I can't fill it in!"

"The fuller the true balloon is filled, the stronger the pressure of the true qi that is shot out in an instant, and the more it can be applied to some high-level true qi magic weapons, so it is called a high-level true balloon."

"If the pressure is insufficient, and the output of true qi is soft, then it can only be used on civil magic weapons, so it is called a low-level true balloon."

"The rules of our Tieyuan Sixth Department are like this, ordinary people farm, weave, work hard in the factory, and earn a meager income."

"Qi refiners are supported by ordinary people, and they can also enjoy a lot of fish and meat, and they have priority to enjoy various resources, so they don't have to be disturbed by trivial chores, and they can devote themselves to cultivation and fighting."

"And our responsibilities are two, the first is to kill the demon beast and fight against the heavenly calamity; Second, it is to continuously provide a large number of real balloons to come out, as the most valuable energy source for the entire tribe! ”

Li Yao nodded, the environment on the Tieyuan Star was even worse than that of the Tianyuan Realm, and the threat it faced was greater, ordinary people and qi refiners performed their duties and did their best, so that they could continue the fire of civilization with difficulty.

Wu Ma Yan said again: "The tickets for the two of us were originally filled with two low-level true balloons, but generally speaking, no matter on any occasion, as long as they can do it, the qi refiner will pour out some more true balloons, although he is a little tired, but every time he has one more true balloon, the tribe can grow by one point!" ”

At this time, the True Qi Rail Train passed through a high-rise building, and under the afterglow of the setting sun, the steel jungle, the golden scales flashed, the red light rose, and it was brilliant.
