Barbarian in Douluo

Chapter 166 Chapter 168

Over Wuhun City,
At this time, countless red hydrogen balloons were floating, and there were huge vertical banners tens of meters hanging below, all of which were gold characters on a red background. The characters were as big as a bucket, and they could be seen clearly even hundreds of meters away.

Different slogans were written on all the vertical banners, such as:
"The people of Wuhun City welcome you."

"The working people are the most glorious."

"Salute to the workers who are struggling on the front line of home construction."

"The fifth residential area in Haotian District of Wuhun City has been completed, and the application for accommodation has already begun."

. . . . .

Such a variety of similarities with minor differences.

They are all positive energy and promotional slogans of various things.

Compared with the newspapers that you read with your head down, the vertical banners of hydrogen balloons that you can see when you look up are more eye-catching.

After successfully obtaining hydrogen gas by electrolyzing saturated saline, Tang Sangang thought about making hydrogen balloons for publicity. In the early history, large hot air balloons and hydrogen balloons were sewn with cow’s intestinal membrane, and they were also pasted with paper. "Kongming Lantern" is even made of thin silk brushed with a layer of sealing paint.

The large hydrogen balloons in Wuhun City are all made of the latter, while the hydrogen balloons made of rubber are mostly small toys or decorative purposes, with little practical value.

Lou Gao was very excited after seeing the hydrogen balloon take off, and kept yelling to tie himself to it to let him experience the feeling of flying. After hearing this, Tang Sangang was sweating wildly. Master, you really know how to die!
However, this also gave Tang Sangang an inspiration. Let’s learn about the travel experience of hydrogen balloons or hot air balloons.

It is another tourism project that belongs exclusively to Wuhun City.

In the previous life, the earliest manned voyage in history was a hot air balloon, which was a full 120 years earlier than the Wright brothers' plane took off.Man's yearning for the sky has never stopped, but it was not until the appearance of hot air balloons that manned navigation became a reality for the first time.

Just do what you said, Tang Sangang immediately arranged for people to make Chlorophytum, and then made a large hot air balloon, with Huowu providing flames to lift into the sky, and a wind-type soul master to blow the wind to control the direction, and a mini version of Kilo The airship is complete.

It's a pity that there are relatively few soul masters with flying spirits in Douluo Continent, and a team can still be found by scraping together. Slow-moving units like Kirov airships are simply living targets.

Three days later, a large hot air balloon with a diameter of 15 meters was completed. It was made of the same material as the hydrogen balloon. Take three small women, or two normal-sized men, also for safety reasons.

In his previous life, Tang Sanbang had heard a lot of news that the ropes tied to the large hydrogen balloons on Chlorophytum broke and caused tragedies. The expansion of the radius of the hydrogen balloon will also increase the risk factor. Otherwise, it will be troublesome if a tragedy occurs.

"Hey, why isn't this hydrogen balloon sealed?" Lou Gao looked at the workers who were blowing up the hot air balloon, very puzzled.

"This is a hot air balloon, not a hydrogen balloon. It is difficult to control the direction and landing of a hydrogen balloon after it takes off, but a hot air balloon is different. You can wait and see later." Tang Sangang kept a secret, waiting for the hot air balloon The airbag is fully inflated.

When the airbag was filled with air, Tang Sangang summoned Huo Wu and asked her to light a flame to heat the air in the airbag. Although Huo Wu didn't understand, she did so. The gap was drilled in.

"The temperature should not be too high, be careful to ignite the airbag."

Huo Wu nodded, and precisely controlled each flame. When the air in the airbag gradually heated up, under the world law of rising hot air, the airbag gradually pulsated back and straightened its body.

"Okay! Call Dugu Yan for me, Mr. Lou, with two more we can take off."

When Lou Gao heard this, he was naturally excited and trotted to find someone. He was in the same industrial area, and after half a year, he and Duguyan Dugubo were also very familiar.

Huo Wu glanced at Tang Sangang, "Why, did you see that guy playing drugs again?"

Tang Sangang's face darkened, and he said in a bad mood: "What are you thinking, Dugu Yan has a sweetheart, and am I that kind of person?"

"Isn't it?"

"of course not!"

Tang Sangang's face was full of righteousness, and he spoke righteously. He always liked to be passive.

"Hmph! I heard that you are merciful everywhere. Besides His Majesty the Pope, Xiao Wu, Zhu Zhuqing, there is also a girl named Qian Renxue who likes you. I also heard that Hu Liena from the Spirit Hall is also interested in you."

"It's all rumors, it's fake, I've only met that Hu Liena twice, I haven't recognized her face yet, where did this thing come from, and where did you hear the news?" Tang San barged With a puzzled face, he really didn't know about it.

Huo Wu looked at Tang Sangang as if looking at a big pig's hoof, "I live very close to Wuhun Academy, you understand."

Tang San said in his heart that I don't know what a fart, a few of you are enough for me to drink a pot, and a few more people really think I am Lord Wei.

"I'm not, I don't, don't talk nonsense!"

Just as Tang Sangang and Huowu were bickering, Lou Gao appeared with Duguyan and another person whom he hadn't seen for a long time, that is Yu Tianheng.

Tang Sangang hurriedly changed the subject, "Xiaoyu, when did you come? Why didn't you tell me, I'll help you catch the wind."

The words were extremely cordial, and he did not treat this very likely future boss of the Blue Electric Overlord Longzong as a stranger at all, as if he hadn't seen an old friend for many years.

Yu Tianheng looked embarrassed. Is this how the strong call others?It's really unique, even if you call it Xiaotian!

"Hahaha, Boss Tang, I haven't seen you for more than a year. I also passed by Wuhun City, and I stopped by to see Yanzi."

"Don't worry, your geese can't fly."

Tang Sangang looked at the two with a smile, Xiao Biesheng was newly married, and the two were in a long-distance relationship. Would anyone believe Yu Tianheng when he said that he was passing by?It's best for Dugu Yan to keep Yu Tianheng for a year or so. After living in Wuhun City for a while, he will completely like this city, and his previous impression of Wuhun Palace will be greatly changed.

Yu Tianheng and Dugu Yan smiled, everything was kept silent.

Dugu Bo looked at this scene from a distance and sighed, the girl is not going to stay, the granddaughter will leave sooner or later, but what should I do if there is no movement on my side?After all, it is old. . .

Lou Gao grew impatient watching them flirt and yelled, "Hey, hey, today's hot air balloon is the main character! It won't go up to the sky yet!"

After speaking, he jumped directly into the spider plant. Seeing this, Tang Sangang had no choice but to let everyone enter the spider plant first, dismiss the workers, and let Huo Wu gradually increase the firepower. The airbag tightly pulled the spider plant under the action of heat. The buoyancy of the balloon is greater than that of the five people plus the gravity of the spider plant, and the hot air balloon starts to lift the spider plant gradually.

The workers below opened their eyes wide. This is the second object they have seen that can fly besides the hydrogen balloon, and it can also fly with people.

Looking at the familiar scene below, Tang Sanbang didn't feel fluctuated in his heart, but Huo Wu and Lou Gao were very excited when they saw the ground from a height of tens of meters for the first time. He stared wide open, unable to hide his joyful look.

Looking down from here, Wuhun City seems to be within reach. The outermost road named "Second Ring" has been built, and the road extending from the city wall connects it together. In addition, the inner part has begun to take shape. Large-scale streets separate the blocks like spider webs.

The various factories in the industrial zone are nothing more than toys the size of a matchbox at this time, and the Wuhun District in the center is full of ranks and extremely prosperous. If you want other districts to catch up, you have to spend a lot of money. less time.

"This feeling is really great!"

Lou Gao jumped up excitedly, almost fell out of the spider plant, Tang Sangang hurriedly held it down, and at the same time told Huo Wu not to stop the flames.

"It's too early for you to be happy, so where is it!" Tang San said with a smile,

"How can you be unhappy! This is the first time I look at the world from such a high position! I also experienced the feeling of a giant once!"

Tang Sangang was ashamed, which giant can grow nearly [-] meters in height.

"Let's take you to see the scenery in other places!"

Casually releasing a wind element skill, the hot air balloon was blown away from the sky above Wuhun City gradually. At the same time, Huo Wu did not increase its firepower, and the hot air balloon remained at a safe altitude.After all, no matter how high the airflow is, it is easy to go wrong.

Huo Wu's eyes in the air shone with an inexplicable brilliance, the long distance between the ground seemed to be one step away at this height, and her heart seemed to be getting closer and closer to this guy.

Lou Gao was still looking down at the ground, while Yu Tianheng and Dugu Yan had already made out. With such a beautiful scene, how can we not seize the opportunity?

Huo Wu took a step forward and put her lips together, hugging Tang Sangang tightly in her arms, Tang Sangang only felt soft and comfortable at this moment, if only he and Huo Wu were alone,

Isn't it a thousand miles a day on this hot air balloon?
When Tang Sangang was thinking wildly, Huo Wu let go of his arms and pushed him away, as if nothing happened, but blushed, and glared at Tang Sangang, as if she had suffered a big loss.

Tang Sangang looked confused, did he think there were people around?

Then another day. . .

The hot air balloon flew around Wuhun City, and finally returned to the industrial area. Lou Gao was shaking with excitement, and he didn't know if there was an element of fear of heights in it, but the others were quite normal, Tang Sangang said Let Lou Gao figure out the key points that need to be paid attention to in manned hydrogen balloon flight.

As for this hot air balloon, other excellent fire control soul masters can also control it, so it should be treated as an amusement project.Of course, in order to let everyone know, publicity is also an essential part.

Moderate relaxation is good for the body and mind, and can improve work efficiency. Tang Sangang deeply believed in this sentence. Sure enough, after a week, Dugu Yan successfully produced nitric acid.

The air is rapidly cooled and turned into a liquid state, and then the nitrogen and oxygen are separated by slowly increasing the temperature by using the characteristic that the boiling point of nitrogen is lower than that of oxygen.

Nitrogen and oxygen undergo two steps to generate carbon dioxide under discharge conditions, which is nitric acid after being dissolved in water.

The whole process uses only ice-type soul masters and thunder-type soul masters, which are highly efficient and pollution-free, and are truly pioneers in energy saving and emission reduction.
