In the night, the Zeppelin glided quietly in the air, and after more than ten hours of flight, the airship had now arrived in the sky over the southern part of the Jibulati Empire.

Underneath the airship is the Duchy of Nguyen Yue, where the Jibulati Empire and the Blue Flag Empire meet.

This principality is located on a peninsula in the southwest sea of the Blue Flag Empire, although it is a principality, but the population is not large, and the reason for this is mainly due to the topography here.

The Principality of Nguyen Yue is a subtropical rainforest landform, and there are many mountains here, and there are heavy tropical rainforests everywhere, which is not suitable for human habitation.

It is precisely because of this topography that the powerful troops of the original Miller the Great did not sweep this area.

"Your Excellency Commander-in-Chief, the current at high altitude is very unstable now, and it is more dangerous for the airship to fly at such an altitude, please ask if you want to lower the altitude."

Although it was already early in the morning at this time, except for Nabu who was excited for several hours in the airship, he fell into a dream, Sean and Mu Jiu didn't feel sleepy at all, although they couldn't see any scenery outside the porthole, but the two of them stood in the command cabin with taste and watched the boring operations of those crew members.

"Yes, how far is it from the Blue Flag Empire now?"

Hearing Captain Li Yue's report, Mu Jiu thought for a while and agreed, and asked him where he was now.

"Report to Your Excellency Commander-in-Chief, now we are in the sky above the Principality of Nguyen Yue, according to the setting of the route, if there are no accidents, we will enter the airspace of the Blue Flag Empire at around 7 o'clock today."

Captain Li Yue skillfully checked the route map, and then reported to Mu Jiu.

"Well, during the day, if the situation allows, we must not fly at low altitude, and try not to expose our tracks."

After looking at the time in the command cabin, Mu Jiu deliberately explained.

Mu Jiu did not do this because he was afraid that the low-altitude flight of the airship would be intercepted by the Blue Flag Empire, after all, in this era, except for his airship, there is no flying machine, so it is said that there are very few weapons that can threaten low-altitude in this era, although the range of those artillery has reached several kilometers, but there is no air defense awareness in this era, so the elevation angle of all artillery is impossible to shoot at the air.

But if such a big airship appeared rashly, it would definitely attract the attention of the officials of the Blue Flag Empire, and Mu Jiu was afraid that it would cause unnecessary trouble.

"Okay, Your Excellency Commander-in-Chief, when we have passed this turbulence, the airship will fly back to high altitude."

Captain Li Yue turned around and began to order the airship to descend in altitude.

Although the rainforest of the Principality of Nguyen Yue is densely covered with mountains and dense forests, the height of the mountain peaks is not very high, and the highest peak does not exceed 1300 meters, so there is no danger for the airship to fly at low altitude under the stratosphere in the dark night, so the airship descended to about 1500 meters before it began to continue flying in the direction of the Blue Flag Empire.

The place where the Blue Flag Empire and the Duchy of Nguyen Yue meet is called Ao Yun Province, and the ethnic composition here is very complex.

Although it is a mountainous terrain here, the population is much more than that of the Duchy of Nguyen, after all, although Emperor Miller did not have the heart to eat the chicken ribs of the Duchy of Ruanyue, he liked a special product of Aoyun Province very much, that is, jade produced in Aoyun Province and the Principality of Nguyen Yue.

Jade has been the most noble gem of the Wasi people since ancient times, and this kind of jade is very rare, so every piece of high-quality jade is worth a lot of money in the Wasi Autonomous Territory of the Blue Banner Empire, and later the favorite of the Emperor Miller has doubled the value of these jades, which has caused a large number of prospectors to gather in the barren land of Aoyun Province.

The Blue Banner Empire does not have many garrisons in Ao Yun Province, most of them are controlled by some local Tusi armed forces, but in the various passes of the Lang Vier Mountains on the border with the Duchy of Nguyen, there is a regimental border force stationed.

In a garrison camp in the Longville Mountains, the supreme commander here, Major William, hurried to the observation post on the top of the mountain early under the leadership of several sentries.

Because they knew that a situation like today's was rare, after all, the mountains were high and the emperor was far away, and Major William was the supreme commander here, and he would usually play with the young prostitutes who had been smuggled into the barracks until late at night, and the barracks would not leave their barracks until after the morning exercise time.

However, Major William did not look at these nervous officers and soldiers, and went straight to the observation room, picked up the high-powered glasses on the table, and looked at the sky in the direction of the Nguyen Yue Empire through the narrow window of the observation room.

"What the hell is this, the height is at least more than 6,000 meters now, and the appearance of that thing is still climbing."

In the telescope, in the sky at least a few kilometers away from the observation post, a black shadow is slowly climbing, but at this time the sun has not yet come out, although the sky has been reflected by red light, but the distance is too far, or the black shadow is a little big, otherwise even the telescope will not be able to detect this strange object.

"When did you see this?"

Although he couldn't see the specific appearance clearly, the huge size and the continuous climbing action still made Major William attach great importance to it, and immediately asked the sentry officer beside him.

"Report to Your Excellency Major, I accidentally saw it ten minutes ago, when it was only a little more than a thousand meters high, and it was flying in our direction, so I immediately called the duty room of the camp."

"Well, you do a good job, you can fly, you can turn, your body is still so big, but you don't look like an ordinary bird, I think it must be a man-made tool, it seems that there is something moving on the side of the Jibulati Empire."

Although Major William is obsessed with women, as a colonel who graduated from the Imperial Military Academy, he is definitely not less sensitive to these anomalies, so when he saw this mysterious object that was still rising, he immediately linked it to the military operations of the Jibulati Empire.

"Let the herald immediately report the situation to the Southwest Military Region, and raise the combat readiness level of the camp in addition, and cancel all vacations......"

Major William lowered the telescope in his hand, for the mysterious object had already left a small dot in the telescope. In addition, the sunlight had already illuminated half of the sky red, and the dot had disappeared without a trace in the telescope.
