Under Chen Wen's order, the fifteen soldiers began to act, and in a short while the hot air balloon was assembled by them.

At this time, fifteen early Ming Air Force pilots were divided into three groups, standing in front of the hot air balloons they assembled!

The originally shriveled hot air balloon balloon is now filled with hot air gas because of the flames!

"Report to Chen Shuai! The hot air balloon vehicle is ready! Please provide the next instructions!"

After everyone was ready to stand at attention, Zhang Zheng, the only household in the team, immediately ran to Chen Wen to report.

"Well! Now I order you! Get on the hot air balloon vehicle right away!"

After hearing the report, Chen Wen nodded with satisfaction and then issued the latest instructions to everyone.

"Yes! Chen Shuai!"

Zhang Zheng, who heard the order, first responded to Chen Wen, and then urged everyone to board the hot air balloon basket.

As the rope that fixed the hot air balloons was released, the five hot air balloons began to slowly fly into the sky under the principle of thermal expansion and contraction.

Due to the limitations of the times' technology, Chen Wen can only create this kind of slowly rising hot air balloon, and only the kind of hot air balloon that can quickly climb by increasing firepower. Chen Wen has no way to create it yet!

After all, it is still difficult to create a device that controls the size of flames in a battlefield where materials are lacking!

However, these five hot air balloons are just Chen Wen's test aircraft. Chen Wen still has to wait until he returns to Yingtian before he has time to settle down and continue his research!

Although these hot air balloons are test aircraft, it is still more than enough to train the first generation of the Ming Dynasty and to carry out some temporary combat missions!

While thinking about the old days, the hot air balloon also successfully reached the air!

Above hundreds of meters high, the Ming soldiers on the hot air balloon could clearly see the things on the ground, and even Sain Sanda in the distance could see clearly!

Of course, the hot air balloons are extremely conspicuous in the sky. Not only the soldiers of the Ming army discovered the hot air balloons in the air, but even the Northern Yuan army on Sain Sanda's side also discovered it!

However, the Ming army seemed very calm about the hot air balloons in the air. After all, when Chen Wen built these five hot air balloons, it was well known to all the soldiers of the Ming army!

But in the Sain Sanda city in the distance, the soldiers of the Northern Yuan army had never seen such things before, and they were a little panicked when they saw them!

"Boss! Look at the place where the Ming army is stationed, what are flying in the air?"

After discovering the hot air balloon group above the Ming army's garrison, a soldier from the Northern Yuan Dynasty hurriedly reported.

"I don't know this...this is not true! You are here to watch, and I will report to General Bonuci!"

The Northern Yuan army soldier, who was called the boss, heard the shouts of his younger brother below, quickly rubbed his eyes and looked over the Ming army.

In this era, people dare not even imagine anything in the sky, so how can they understand what this hot air balloon is for?

Although the Northern Yuan soldiers didn't understand, he immediately gave instructions to his subordinates, continued to stare at the movements of the Ming army, and immediately rushed towards the general's mansion in the inner city.

The General Bonus he mentioned was the main general sent by the Northern Yuan Dynasty to defend Sainanda!

The last time Chen Wen used artillery to destroy the city wall, he discovered something wrong first and took some soldiers out of the city wall, and then he luckily left his life!

"General Bonus! I have important situation reports from my subordinates!"

The Beiyuan soldier who came to report to the general came to search for Bonuci, hoping to report to him about the situation in the Ming army's air.

"Don't make a noise! ​​Lord Bonuci hasn't had a rest for several days! Just report to this deputy when you have any questions!"

After hearing the shouts of the informing soldier, Bonuci, the main general, did not appear. The one who came to the soldier was his deputy general Halter!

During this period, Bonuci was afraid of the sudden attack of the Ming army, so he was always on the front line. Seeing that his body was weak day by day, Halter finally persuaded the other party to return to the general's mansion to rest.

Now suddenly a soldier is about to wake up Bonuci to report the situation. How can this deputy general Halter allow it?

He said, asking the soldier who was informed to report to him directly if there was any situation.

"Deputy General Halter! Suddenly there were a bunch of strange things flying over the Ming army!"

After hearing the words of the deputy general Halter, the soldier also felt that there was not much difference between the situation and the deputy general.

So he reported what he wanted to report to the deputy general Halter.

"Well? There is a strange phenomenon over the Ming army?"

"Let me lead the way! I'll go and have a look!"

After hearing the soldier's report, the North Yuan deputy general Halter also felt a little strange.

So, the soldier asked him to take him to see what the Ming army was doing!

"Yes! Deputy Halter!"

After hearing the words of the second-in-command of Saiyinsanda's city guard, the Beiyuan soldiers who were rumored to be sent to the collapsed city wall without any hesitation.

After all, Saiyin Sanda was one of the big cities in the northern desert of the Northern Yuan Dynasty, so he also learned from the Han people in the Central Plains to divide them into inner cities and outer cities!

The Beiyuan's General's Mansion in Sainshanda is in the inner city, and it still takes a lot of time to get to the collapsed walls of the outer city!

In order to save time, the two of them rode directly to the outer city!

After reaching the collapsed city wall, Halter, the deputy general of the Northern Yuan Dynasty defending the city, also drove the horses to stop.

The collapsed city wall is closest to the Ming army's garrison point, so you can clearly see a group of hot air balloons floating above the Ming army, composed of five hot air balloons!

Looking at the hot air balloons floating around in the air, although Halter was a little confused, he did not take the matter to heart.

In his eyes, the "thing" flying over the Ming army should be what the people of the Central Plains call kite!

As for why this "kite" is so big? What role it will play in the battlefield, Halter doesn't know or think about it!

"Hmph! Mingjun is flying kites at their base. Do you also want to report such small matters?"

"I just hurried to the General Bonuci to find General Bonuci. I thought you had any urgent military information to report!"

After looking at the hot air balloons above the Ming army in the distance, Halter cursed with surprise angrily.

Obviously he was very dissatisfied with the soldier’s notice!

"Come on! Arrest this soldier and deal with him after the war to defend the city ends!"

When the soldier wanted to say something, Deputy General Halter did not give the other party any chance, and directly sent the former into the prison in the city!
Chapter completed!
