For the purpose of confusing the main messenger behind the scenes, Yuan Fang knew that there would be no result, but he still let Yin Ning and the people of the dark night continue to search, and they had to make a big fanfare, and the bigger the movement, the better.

At the same time, Yang Xing tacitly used diplomatic channels to send the feather arrows of the Wen'an Empire used by the assassins to the copywriting empire to be handed over to Prime Minister Liu Cheng, and sent a letter together, Yang Xing explained in a gentle tone that all this was the conspiracy of the other party, they did this to drive a wedge between the Dongsheng Empire and the Wen'an Empire, and then break each one, Yang Xing sincerely said that he would not affect the friendship between the two countries because of the other party's discord, the relationship between the alliance is still stable, and he also hopes to form a marriage with Liu Chengxiang, Marry the princess to Prime Minister Liu's second son to strengthen the trust and friendship between the two parties. Yang Xing's posture was very low, and even had some flattering meaning, all in order to cooperate with Yuan Fang's intentions, to show weakness, in order to test the ambitions of the Wen'an Empire.

Dugu Zhen is in a good mood today, he is almost about to collapse these days, the Wanliu Empire is constantly fighting, and they would rather the empire be in the cracks, once the war starts, they would rather the empire bear the brunt of becoming the key target of the Wanliu Empire, because only in this way can the transportation lines of the two continents in the north and south of the Wanliu Empire be opened, and now the Ningliu Empire is full of devastation, and there is no self-protection power in the face of the Wanliu Empire, and now the Wanliu Empire has not done anything to them, and it completely relies on the air force of the Dongsheng Empire, but once the war breaks out, The Dongsheng Empire will face several times the enemy army of its own, and when the time comes, the Dongsheng Empire will definitely invest all its forces in order to fight against a strong enemy, at that time, it is better for the Empire to lose the protection of the Dongsheng Empire's air force, where should they go.

Dugu Zhen has been worried about this, but today, this problem has finally been solved, because today he received a letter from the Emperor of the Dongsheng Empire, which also attached a drawing, Dugu Zhen laughed after reading the letter, and immediately ordered to gather all the craftsmen and all the materials that could be used nearby, and began to manufacture his own airship on a large scale, and at the same time, take out some of the fog stones sent together and hand them over to the people below, especially the officials in charge of minerals, so that they can carefully search for fog stone mines in the empire, if they can find fog stones in the country, Then in the future, I would rather that the Empire's air force would no longer be subject to the constraints of the Dongsheng Empire, and even if it couldn't be found, it would at least be able to temporarily solve the current crisis.

The good news is not only that, Yang Xing said in the letter that he would support at least one hundred airships in the Rather Empire, but for the reason that the Empire would rather lack qualified pilots, Yang Xing hoped that Dugu Zhen could send people to the Air Force Academy to study as soon as possible, and strive to master the piloting and maintenance of airships as soon as possible, and then hand over the hundred airships to these students, so that they could directly drive the airships back to China to participate in the war.

At this time, the situation in the northern continent was very tense, with the Dongsheng Empire as the mainstay, and the Wen'an Empire and the allies who would rather be supplemented by the Empire confronted the coalition forces of the Wanliu Empire, the Yuanhe Empire and the Liusang Empire.

The Wanliu Empire is still increasing troops to the Yuanhe Empire, and the Yuanhe Empire is also equipped with airships and is training intensively.

The Wen'an Empire and the Rather Empire are almost the same, using all the time to build airships, train pilots, prepare strategic materials, and fire oil, which have become a sought-after commodity in the Northern Continent, and the price has skyrocketed to several times or even more than ten times the original.

On the day when Dugu Zhen received the airship drawings sent by Yang Xing, he sent 2,000 troops from the Praetorian Guard to take the transport boat of the Dongsheng Empire to the Air Force Academy in Nanzhou to study for further study, Yuan Fang had already arranged a suitable instructor and venue, but they did not study in the Emerald Island, but temporarily built a foreign Air Force Academy in the coastal area of Xiaguan County, Nanzhou, the Emerald Island was rumbling every day, and Yuan Fang did not want to expose his killer skills before the start of the war.

Time is limited, I would rather the pilots and air and ground crews of the empire after five days of intensive training, and finally be able to barely control the airship, on the sixth day, the first air force unit of the empire will drive a hundred airships transferred from Beizhou by Yang Xing to return to China in a queue, and with them will go back with ten Dongsheng imperial pilots who have just graduated, and return to the Ning Empire as instructors to teach the students to continue to complete the rest of their studies.

Yuan Fang thought that the big war was coming, but he didn't expect these guys to be obsessed with building airships one by one, and they all kept their heads shut behind closed doors, constantly enriching their strength and gaining greater advantages.

Rather the empire is really war-torn, the national strength has been empty to the extreme, it is not easy to build an airship, the amount of various materials and materials required is extremely huge, and the only bit of funds that can be used by the treasury will be quickly exhausted, Dugu really wanted to borrow money like the Dongsheng Empire, but people have been very generous and unconditionally gave themselves the manufacturing drawings of the airship, and also provided so many fog stones for free, Dugu Zhen is embarrassed to open his mouth even if he is thick-skinned.

Poor change, change is common, this is the eternal truth, since the material is insufficient, then streamline the expenditure, after the analysis and research of professionals, finally Dugu Zhen decided to give up the most time-consuming and laborious and financially expensive external armor and all unnecessary devices outside the airship, the final formed airship has only a leather airbag and a thin layer of wooden plate armor, an ordinary hardwood cockpit, it looks quite simple, not to mention any defense, compared with the Dongsheng Empire with strong external armor, If the airships of the Dongsheng Empire are heavy cavalry, I would rather the airships of the Empire be cannon fodder without any protection, and a casual heavy crossbow can easily penetrate their protection.

Although the Empire's airship was rudimentary, to everyone's expectations, the flight performance of this airship was surprisingly good, and its speed was more than a little faster than the armored Dongsheng Empire's airship. When the news was transmitted back to the Dongsheng Empire, it immediately attracted great attention from the military, but Yuan Fang did not care at all, such a result he had already made it clear, if he wanted to have enough defense, he must strengthen the outer armor, the thicker the outer armor, the greater the weight, compared to the naked boat with nothing, of course, it will appear bulky, this is inevitable, as for the speed of the airship was overtaken by the Ningyuan Empire, Yuan Fang did not take it seriously, wanted to overtake, Yuan Fang has a way, but now is not the time, the hole cards have to be dried one by one, It wouldn't be fun to take it all out at once.
