"You have to be careful with this thing!" Two strange-looking metal devices were placed under the huge air inlet of the hot air balloon. If one wanted to touch these two devices that were currently emitting light blue flames, they would need to be stretched very high, and could not be easily touched. The soldier with the rank of second lieutenant said to his companion in the basket, "After this thing burns, you must not touch it.
"Don't ever touch this thing after it's on fire. If you do, you'll be cooked alive." After saying that, Second Lieutenant Li Ji raised his hand. There was a white scar on the back of his hand. This scar was obviously just healed not long ago, and there was neither hair nor texture on it. It was just a white thing.
The one who boarded the hot air balloon with Li Ji was a sergeant. The artillery observer was a technical soldier, and his military rank was not low. If one did not pass the cultural examination, they would not have the opportunity to join this department.
"What is this thing called a lamp?" The sergeant was called Wu Wenguang, and there were four flags on his waist, two red and two green. Once the hot air balloon rose to a certain height, it would be useless to rely on shouting. Moreover, once the battlefield opened fire, under the sound of guns and cannons, the human voice was completely useless. Therefore, Vézé's troops had a semaphore unit for a long time. Although the smoke on the battlefield would also affect vision, it was better to have semaphore than no semaphore.
"This is called an alcohol burner, and it can continuously blow hot air into the hot air balloon. If we don't use this, but other things, this hot air balloon will not fly at all. "Second Lieutenant Li Ji replied.
How to provide heat to the hot air balloon was a very big problem. The outer shell of the hot air balloon was mainly made of silk, and if the temperature of the hot air was too high, holes would immediately appear on the outer shell. If the temperature of the hot air was insufficient, and the density difference between the hot air and the cool air outside was too small, it would not produce enough buoyancy.
Vézé originally had a headache about this, and then he remembered the plot of the TV series' Around the World in 80 Days'. When the hot air balloon ran out of fuel, they directly used alcohol. And those who were engaged in mechanical processing were very clear about the principle of the alcohol burner. By heating the liquid fuel into a high temperature and high pressure gaseous state, it could be fully mixed with the air and burn, providing the maximum amount of heat. In order to process gunpowder, Vézé's troops had alcohol distillation equipment, so there was no shortage of alcohol. After solving the heat source during liftoff, the hot-air balloon's biggest difficulty was solved.
The hot-air balloon with a diameter of more than six meters had already become round and bulging. A large circle of heavy sandbags was hung on the edge of the bamboo basket that carried the passengers.
"Are you ready?" asked Deputy Commander Cai Yubin.
"Don't worry! We're ready! "Second Lieutenant Li Ji replied excitedly. Even though he had been on a balloon five times, the excitement he felt was still the same. People in China believe that only immortals can fly in space. Second Lieutenant Li Ji's physics studies were quite good, and he had firmly grasped the law of buoyancy. He did not have any theoretical problems with hot air balloons. To Second Lieutenant Li Ji, he felt even happier after cutting off the idea of being an immortal. Although there were still too many things he didn't understand about the things taught by Chief of the General Staff Vézé, Li Ji had learned a whole new world of physics. Since it was already possible to fly in the sky in this brand new world, then the other magic that the immortals possessed could also be realized. Second Lieutenant Li Ji had absolute confidence in this.
Seeing that Second Lieutenant Li Ji was full of energy and in good condition, Cai Yubin ordered, "Then let's take off!"
"Everyone retreat, retreat beyond the safety line!" The commander immediately ordered. One of the powers of the General Staff Headquarters was to formulate various drill manuals and rules. After merging with the Combat Training Department, the authority of the General Staff Headquarters was even more expanded. Even for this new hot-air balloon, there were specialized personnel who began to edit the rules based on their experience.
In Vézé's troops, there had been cases of people falling from a high altitude during training and injuring the people below. That was when Vézé attacked Wujia Town near Wuzhou in Guangxi and conducted airborne training. Therefore, these experiences were recorded and used as the basis for formulating rules and regulations. Up until now, as long as there were no problems with Vézé's General Staff Headquarters, retreating to a safe area to prevent falling objects from hitting them was one of the things that had to be considered when formulating matters related to high altitude.
As soon as the commander shouted, Deputy Commander Cai Yubin, Deputy Chief of Staff Ju Junfeng, and the other officers began to obey the order and began to retreat. These officers had all received training from the General Staff Headquarters, and many of them had participated in the establishment of the General Staff Headquarters. At the very least, everyone had to obey the rules that they themselves approved of.
With the officers taking the lead, the soldiers who wanted to see the excitement also began to retreat. With the hot-air balloon's basket as the center, apart from the commander and a few staff members, there was a large empty space.
"Put down the sandbags!" The commander shouted.
Pulling the knots, several sandbags fell from the side of the basket to the ground. With a jolt, the hot-air balloon slowly began to rise. One end of the rope was tied to the basket of the hot-air balloon, while the other end was tied to a wooden stake that had been driven deep into the ground. As the hot-air balloon gradually rose, the rope was gradually pulled up. From a distance, it looked like a completely disproportionate tail under the head of a strange tadpole.
"If you want to see a thousand miles, you must go higher!" This was the sixth time Second Lieutenant Li Ji had been on a hot-air balloon, but he couldn't help but use a phrase from the Tang Dynasty poet Wang Zhihuan's "Ascending the Stork Tower", which was widely circulated among the hot-air balloon troops.
Second Lieutenant Li Ji was from Anhui's Tong City, which was the base of the famous Tong City School. However, Second Lieutenant Li Ji was born into a small landlord's family, so he didn't have the opportunity to really come into contact with the big shots of the Tong City School and their children. After Vézé occupied this area, his grandfather had no choice but to let Li Ji join the army for the sake of his family's livelihood, so that his family could get the treatment of a soldier's family in order to share the amount of grain taxes that his family had to pay.
However, after joining the army, Li Ji discovered that the knowledge he had learned didn't count here. What was taught here was other knowledge, and it was knowledge that Li Ji liked very much. After passing the exams, he was forced to devote himself to an even more arduous learning process. Mastering the formulas and methods of using those physics, mathematics, and geometry allowed Li Ji to become a Second Lieutenant. Li Ji felt that this was only natural. After all, he was an educated person from Tong City. How could he lose to a country bumpkin who had never been educated?
