"You've got to be careful with this!" Two strange-looking metal guys sit underneath the huge air intakes of the hot air balloon. If you want to touch these two devices with your hands that are whirring with light blue flames, you need to be very high, and you can't touch them lightly. The soldier with the second lieutenant badge among the two observers in the basket said to his companion.

"This guy must not touch it after it is burned, if you dare to touch it, a piece of meat can be scalded." After speaking, Second Lieutenant Li Ji raised his hand, and saw a white scar on the back of his hand, which had obviously just healed from the burn, and there was no hair or texture on it, it was just such a white thing.

A sergeant was followed by a sergeant, and the artillery observer was a technical unit, and the rank was not low. If you don't have a Guò cultural exam, you won't have the opportunity to participate in this department.

"What's this thing called?" The sergeant's name was Wu Wenguang, and he had four flags planted in his waist, two red and two green. Once the hot air balloon rises to a certain height, it is useless to shout again. And once the fire is fired on the battlefield, under the sound of gunfire, the human voice is completely incompatible. So there were banner troops in Weezer's troops very early. Although the smoke on the battlefield can also affect the vision, it is much better to have a flag than not to have a flag at all.

"It's called an alcohol blowtorch, and it spews hot air into a hot air balloon. If it weren't for this, but with someone else, this hot air balloon wouldn't have been able to fly. Second Lieutenant Li Ji replied.

How to provide a heat source to the hot air balloon is a big problem, the shell of the hot air balloon is a silk-based guy, and the hot air temperature is too high, and the shell immediately burns out holes. If the temperature of the hot air is insufficient, the density difference between the hot air and the cool air outside is too small, and it will not produce enough buoyancy.

Weser also had a headache about this, but he remembered the plot of the TV series "Eighty Days Around the World", when the hot air balloon was running low on fuel, they directly used alcohol. Those who are engaged in mechanical processing are very clear about the principle of alcohol blowtorches. The liquid fuel is heated into a gaseous state with high temperature and high pressure, which can be fully mixed with air for combustion to provide maximum heat for combustion. In order to dispose of gunpowder, there was an alcohol distillation equipment in Weeser's troops, and there was no shortage of alcohol. The heat source during liftoff was solved, and the biggest difficulty of the hot air balloon was broken.

The hot air balloon, which was more than six meters in diameter, had become swollen by this time, and a large circle of heavy sandbags hung on the edge of the bamboo basket that carried people.

"Are you ready?" Deputy Marshal Cai Yubin asked.

"Don't worry! We're all set! Second Lieutenant Li Ji replied excitedly. Even though he had been on the balloon five times, the excitement had not changed. Chinese believe that only immortals can fly in space. Second Lieutenant Li Ji studied physics quite well, firmly grasped the law of buoyancy, and did not have any theoretical incomprehension about hot air balloons. For Second Lieutenant Li Ji, after breaking off the idea of immortals, he felt even happier. Although he still has too many things to understand about what the Chief of the General Staff, Professor Wei Ze, has given to everyone, the physics he has learned has opened up a whole new world to Second Lieutenant Li Ji. Since it has been possible to truly fly in this new world, then the other spells possessed by the immortals must also be able to achieve it. Second Lieutenant Li Ji has absolute confidence in this.

Seeing that Second Lieutenant Li Ji was in good spirits and in good condition, Cai Yubin ordered: "Then take it off!" ”

"Everybody get out of the way, get out of the way!" The commander immediately ordered. One of the powers of the General Staff is to formulate various rules and regulations. After the merger of the Combat Training Department, the authority of the General Staff was further expanded. Even in this new hot air balloon, there are special personnel who start editing the rules of use based on experience.

In Weeser's troops, there was a case of someone falling from a high place during training, and as a result, he was killed and injured by the people below. That was when Wei Ze was conducting airborne training when he attacked Wujia Town, near Wuzhou, Guangxi. Therefore, these experiences are recorded and considered as the basis for the development of the system. Up to now, as long as there are no problems with Weese's General Staff, then everything related to the high altitude, retreating to a safe area, and preventing being hit by objects falling from a high altitude must be one of the contents to be considered.

As soon as the personnel in charge of the command shouted, Deputy Army Marshal Cai Yubin, Deputy Chief of Staff Ju Junfeng, and other officers took the lead in obeying the order and began to retreat. These officers have all been trained by the General Staff, and many of them have participated in the construction of the General Staff, so they must at least obey the rules that they agree with.

Officers took the lead, and the soldiers, who were very eager to see the excitement, also retreated. Centered on the gondola of the hot air balloon, a large open space was vacated except for the commander and a few staff members.

"Put down the sandbag!" The commander shouted.

Pulling the knot, several sandbags fell from the side of the basket to the ground. The hot air balloon shook and slowly began to gain altitude. One rope is tied to the basket of the hot air balloon, and the other end is tied to a stake driven deep into the ground, and the rope is gradually pulled up as the hot air balloon gradually rises. From a distance, it looks like a completely disproportionate little tail under the head of a weird tadpole.

"If you want to be poor, go to the next level!" This is the sixth time that Second Lieutenant Li Ji has been on the hot air balloon, but he still can't help but use the words from the Tang Dynasty poet Wang Zhilian's "Climbing the Stork's Tower", which is widely circulated among the hot air balloon troops.

Second Lieutenant Li Ji is a native of Tongcheng, Anhui Province, and this place is the base of the famous Tongcheng School. However, Second Lieutenant Li Ji was born in a small landlord family, and he did not have the opportunity to really contact the bigwigs of the Tongcheng faction and the children of the bigwigs. After Wei Ze occupied this area, his grandfather had to let Li Ji come out as a soldier for the sake of his family's livelihood, so that his family could be treated as a military family member in order to share the amount of tax paid on the finished grain to his family.

But after really joining the army, the knowledge that Li Ji has learned himself does not count here, what he is talking about here is other knowledge, or the knowledge that Li Ji likes very much. After studying for exams, he was forced to devote himself to a harder study process. Mastering the use of those physics, mathematics, and geometric formulas made Li Ji a second lieutenant. Li Ji felt that this was logical, after all, he was a native of Tongcheng who had read books, how could he not compare to a countryman who had never read a book?

However, after becoming a hot air balloon pilot and artillery observer, Second Lieutenant Li Ji suddenly had a feeling. It's just that he enlisted in the army, and he never had a feeling that he had ever had. He is now an officer under Wei Ze, the king of Qi!
