A few guys who couldn't hold back their internal anxiety ran away with their stomachs in their hands, and the others either stayed in place to talk to each other and discuss what they had just learned, or went out in groups to breathe, and the classroom that was quiet just now was suddenly noisy.

Ji Yu was surrounded by a large group of students asking questions, and the intellectual and academic atmosphere was very strong, Yuan Fang was very pleased, especially asked Sang Rou to secretly write down the few people who were tirelessly chasing Monsoon Yu, and then observe them in the future.

After finally answering the students' questions, Ji Yu came to Yuan Fang and sat down, wiped the fine sweat on his forehead and said bitterly, "Lord Yuan, will you talk about it later?" I can't take it anymore. ”

Yuan Fang patted Ji Yu's shoulder: "You spoke very well, very good, I was fascinated by it, really, I don't fool you, hehe, don't worry, I'm not an unscrupulous contractor, of course I have to let you rest, in this way, you will arrange someone to teach everyone the flag language in a while, this thing must be popularized in the Air Force, this is the only means of communication for our army, navy and air force, and it is equally important." ”

Ji Yu took a breath and said with a smile: "Okay, I'll arrange it." ”

Taking advantage of this time, Yuan Fang made a class schedule, compressing each class to half an hour, that is, an hour, with about ten minutes of rest between classes.

From after breakfast to before dinner, the course arrangement is very compact, from theoretical knowledge to aircraft structure, to flags, pilotage, simple medical first aid, etc., this is the early course arrangement, after a few days, everyone has a certain understanding of the fog balloon and the airship after Yuan Fang also plans to add other courses to improve the students' hands-on ability to carry out practical operations, such as the assembly and disassembly of the fog balloon and the airship and daily maintenance, and finally the piloting flight that everyone is looking forward to, and then, is the tactical and combat formation, Cruising formation, etc., Yuan Fang's is expected to complete all the courses within a month, although the time is broken, but there is no way, the time is limited, and a certain combat effectiveness must be formed as soon as possible.

There are more than 1,000 students who come to study, and there are so many fog balloons and airships, and the competition is very fierce, so how to arrange the rest of the people, Yuan Fang also has his own plans, the combat effectiveness and practical value of the Air Force are obvious to all, but the Air Force is not just a pilot bombardier or something, but also needs more auxiliary personnel, ground crew, equally important, indispensable.

In the next few days, everyone went to class during the day, and at night, Yuan Fang summoned the generals and Sang Rou in the tent to study the problem of battle formations, and sometimes took advantage of the moonlight to fly at night to practice tactical theory.

In the blink of an eye, half a month has passed, the theoretical level of the trainees has improved by leaps and bounds, but there is still no movement on the side of the Liusang Empire, there is some news on the Long Ring Island, through an accidental contact, the reconnaissance boat encountered the Hengsha pirate warship, the navy identified the other party was not embarrassed, but expelled it, the officers on the reconnaissance ship tried to communicate with the pirates, hoping to meet the pirate leader, the captain refused very simply at first, but the next day, they took the initiative to find the reconnaissance ship that was still staying near the Long Ring Island, indicating that they could meet, but that the chief general of the Navy must go to Long Roundabout to meet.

After Yuan Fang got the news, he discussed it with Situ Muran, Yuqing and Chang Xun, and finally decided that the time would be set for twenty days later, and Situ Muran would go to Changhuan Island as a representative.

During this time, Yuan Fang received a lot of battle reports from Dongzhou, I don't know if it was due to the weather or if they had other plans, the Yuanhe Empire slowed down its attack, and the vanguard army was stationed in situ after capturing Qingxia County, which was far away from Chima County, and other troops began to strengthen the defense of the occupied city, it seems that they do not plan to advance in the recent period, but digest the city they have just occupied, but what is puzzling is that their logistics and transportation have not been interrupted, and a steady stream of grain, grass and weapon supplies have been transported from the mainland, and there are still signsAccording to the analysis, the other party's generals should be biased towards stability, do not want to rush forward, and plan to solve the other defenders in Dongzhou before they have any worries.

The Ningyuan Empire was very restless during this time, entangled with more than 100,000 troops to launch a crazy counterattack, although Dugu Zhen was able to fight well, but the gap between the strength of the two sides was too large, and he was defeated and retreated, and most of Guangyuan County was lost.

Overall, the Dongzhou war situation is still at an absolute disadvantage, but what makes everyone a little relieved is that the other party did not attack Dongping County in one go, leaving more time for the Dongsheng Empire, which everyone is very willing to see, but in this way, the pressure on Tang Jian's Dongzhou army has doubled, and the empire really has no more troops to support, how long it can hold out, and how much time to win, the key depends on Tang Jian's Dongzhou army.

Yuan Fang is very tired these days, but he still finds time to make a simple altimeter, which is inspired by a barometric pressure test in the school before, as if it is called a Tolimani experiment, according to this thinking, first put the mercury into the bottle, and then get a long enough glass tube to put it at the mouth of the bottle, with the change in height, the air pressure will change, and the height of the mercury managed by the glass will also change, according to this conclusion, and then according to the height comparison of the ground mountain measurement, the scale is indicated on the glass tube, so that A simple altimeter was completed and mounted on top of the airship and the large fog balloon to measure altitude, although this data was not accurate, and could only calculate altitude rather than actual altitude above the ground, but it was sufficient, and with a reference, it was always more accurate than visual inspection.

Also, Yuan Fang also asked Situ Muran to understand the speed measurement of the sea ship, and then set the speed for the airship with reference to the speed of the ship, so that the altitude and speed have standards, and everyone is consistent, and they are more handy when commanding or formation.

On the eighteenth day of the course, the trainees finally ushered in the first flight course in the envy of other comrades-in-arms, among them, the selected pilots were the most excited, one by one before dawn to get up and prepare, first go out for morning exercises, let the body be active, reach the best state, and then go back to simply wash and change into a special flight suit, and came to the air base to wait while getting together with colleagues to talk about the upcoming first flight.

This is an exciting day, and it is also the first practical exercise of the Imperial Air Force, Yuan Fang, as the leader, naturally came to the base early to arrange preparations, and it is not practical for him to prepare anything, everything has been arranged Ji Yu, he is just as the spiritual leader of the base.
