Deposed Crown Prince: After three years of service on the frontier, the entire court knelt and begge

Yunqing Urgen didn't say a word.

He gave the letter directly to Yan Jia.

After Yan Jia finished reading the letter, his face lit up with excitement.

Yunqing Urgen looked on with curiosity.

Since the letter was addressed to Yan Jia, he did not open it.

"Our prince still refuses to acknowledge himself as a god! How did he foresee our current predicament...?"

Although Yunqing Urgen was not an expert in military affairs, he could tell from Yan Jia's words that their battle was not going well.

He then turned to Yan Jia and asked, "General Yan Jia... what problem have you encountered here?"

Yan Jia then recounted the problems they had encountered and the abnormal fighting style of their Saleh army.

Although Yunqing Urgen was not proficient in military affairs.

However, he also realized at that moment that there was no solution to this problem.

"Could it be that His Highness, thousands of miles away, knew about the predicament here and offered a solution?"

Yan Jia nodded, slightly excited.

Yunqing Urgen was even more puzzled: "Really? Didn't you write to the Prince?"

Yan Jia was both amused and exasperated: "I don't even know where the prince is now... Where am I supposed to write him a letter?"

Yun Qing.Urgen thought about it and asked curiously, "The way they attacked with artillery fire is almost unsolvable... So how did Your Highness break it?"

Yan Jia smiled mysteriously.

Before he could speak, Yunqing Urgen understood and said, "General, if you feel it's inappropriate or inconvenient, it's fine if you don't say anything."

Yan Jia waved his hand and said, "Khan, you're being too polite. There's nothing I can't tell you."

As he spoke, Yan Jia leaned close to Yun Qing.Urgen's ear and whispered something.

Yunqing and Urgen were increasingly surprised as they listened...

"Is this method feasible? It sounds rather far-fetched..."

Yan Jia smiled and said, "Although I'm not entirely sure if it's feasible right now... however, if Your Highness says so... then it's definitely feasible!"

Yunqing Urgen nodded, telling Yan Jia to go ahead and get busy.

He stopped causing trouble and Yan Jia didn't hold back either.

After seeing Yunqing and Urgen off.

Yun Qing.Urgen asked, "By the way, didn't you say that General Wei Wuji was cutting off their supplies from the rear?"

Yan Jia nodded: "We don't know what kind of equipment those people who are resupplying them have. We have to be prepared for both possibilities!"

Or Yan Jia's eyes lit up, and he said to Yun Qing.Urgen, "That's right, Khan... what you said really reminded me! The Prince said in his letter that we must make good use of those prisoners. If they are used properly, it can reduce a lot of trouble..."

Yun Qing.Urgen nodded at first, then asked, "Make reasonable use of it? How do you make reasonable use of it?"

Yan Jia said, "If we let those prisoners pretend that the Saleh people intercept all the weapons at the entrance... wouldn't we be able to get a lot of supplies without lifting a finger or alerting them?"

Yunqing Urgen's eyes lit up immediately after hearing this.

"As expected of a general under the Prince, he's got a sharp mind. That's right, if General Wei Wuji uses force, there are only two outcomes after one battle. Either they stop transporting supplies, or they send reinforcements, such as a team of over a thousand men with those cannons, which could blow General Wei Wuji's men to smithereens."

Yan Jia nodded, then said, "Now there's just one problem... among those people, are there any usable?"

Yun Qing.Urgen said to Yan Jia, "General, have you forgotten? The interrogators that the Prince left us... they have a knack for training people. They selected some Slavs with weaker willpower and have already tamed them all... there are over a hundred prisoners! They were originally intended to use them as spies!"

"I never thought it would come in handy!"

As Yunqing Urgen spoke, his admiration for Xiao Ce grew even stronger.

As they were talking, they ordered Yunqing Urgen to bring over a hundred prisoners.

Yunqing Urgen rushed back.

After seeing him off, Yan Jia didn't rest.

They directly contacted the best craftsmen in the area, and they immediately produced a blueprint.

After inspecting it, the craftsman said there were no problems.

Yan Jia then ordered the suicide squad that was originally going to trick the artillery shells to stop and temporarily cease their operations.

Therefore, one of Wei Wuji's lieutenants personally went to find Yan Jia.

Following Yan Jia's pledge of loyalty, it was said that their people were fearless of any challenge and even less afraid of death.

Looking at their expressions, Yan Jia realized that they thought he was doubting their courage.

Yan Jia laughed and said, "I know you're not afraid of death! So, I'm going to give you a more challenging way to die. Do you dare?"

The lieutenants looked at each other with certainty, and then said to Yan Jia, "Of course we dare... what's there to be afraid of?"

Seeing that they agreed without even thinking, Yan Jia smiled and said, "Aren't you going to ask me what method I'm planning to use?"

These lieutenants first said they were not afraid of anything! They weren't even afraid of death, so they were even more fearless.

As they were talking, one of the lieutenants asked curiously what they were supposed to do.

Yan Jia said to them, "Are you sure you're not afraid of death?"

The lieutenant nodded.

Yan Jia then said to them, "Since we can't deal with those people on the ground, let's go to heaven!"

After hearing Yan Jia's words, the group looked on in astonishment: "Heavens?"

Yan Jia asked one of his attendants, "Is the first hot air balloon ready?"

The attendant nodded and then said, "Your Highness, everything is ready!"

Yan Jia then turned to Wei Wuji's lieutenants with great interest and said, "Are you all ready? Is it too late for you to back out now?"

The lieutenants, full of curiosity, asked, "General, since it's possible to ascend to heaven... wouldn't it be worth it even if you died?"

"Yes, yes... If we could ascend to heaven, then dying would be worthwhile..."

"General, do you really have a way to get to the sky?"

Yan Jia smiled and said, "Not bad..."

As he spoke, Yan Jia led them to a wide-open meadow.

The artisans, who had been hastily assembled, set up a temporary workshop here.

The people in the workshop were all busy; some were cutting silk fabric, while others were making other parts.

On one side, in an open space.

A hot air balloon is ready.

Yan Jia looked at the celestial phenomena with some people who knew how to interpret them, and then measured the wind direction.

It was confirmed that the wind direction was opposite to that of the Slavic armies.

"Then, shall we give it a try together?"

Upon hearing Yan Jia's words, the lieutenant's expression darkened. He said to him, "General, are you going too? It's not appropriate for you to go."

"Indeed, General, you have many things that require your orders... You cannot go..."

Yan Jia laughed and said, "I'm not really sending you to your deaths... This thing was designed by the Prince, and anything designed by the Prince is never unreliable... Come at me all at once."

Yan Jia then ordered the fire to be lit. They used some flammable alcohol and charcoal, and after the heat rose, the hot air balloon took off directly into the air.

Yan Jia was the first to go up, and the others followed.

The guard beside him asked, "General, is it really true that the safety rope has been cut? If it has, then it really will take off!"

The lieutenants who had accompanied him onto the hot air balloon chimed in, "Yes, General Yan Jia, why don't you just forget about it... you don't need to go up, we can go test it out ourselves..."

"You bear a heavy responsibility, what if..."

Seeing their anxious expressions, Yan Jia smiled and said, "Don't worry... nothing bad will happen..."

Seeing that they were dawdling, Yan Jia simply drew his sword and cut the protective rope on one side.

The hot air balloon, now cut in half, immediately took flight due to the force of the rising heat.

Once they reached a certain altitude, Yan Jia adjusted the firepower according to Xiao Ce's instructions, thus controlling the altitude!

This thing is great in every way, except it's very hard to change direction... it's practically drifting with the wind!

Even so, it's still a miracle.

Many of those involved in the project saw several generals take off.

They all knelt down and worshipped, as if they had witnessed a divine miracle.

If Xiao Ce knew that Han Da was personally conducting the experiment, he would definitely curse him.

In fact, Xiao Ce was far away in India.

However, judging by the timeline, the people of the northern desert and the Slavic peoples had already gone to war.

Although he had already explained, he still felt something was amiss, especially given the possibility of the enemy completely overwhelming him with their weapons.

The tactics and suggestions they put forward may not be effective.

He then came up with some more ways to launch a surprise attack, but after much deliberation, he realized that some powerful weapons, if they could be manufactured, were not feasible.

They wouldn't be suppressed anymore, and in a flash of inspiration, he thought of the heavenly fighting method.

Even if the other side is powerful, if they drop bombs from the sky, they definitely won't be able to do anything about it.

He drew up the blueprints based on just a rough idea, even though it wasn't really feasible.

Xiao Ce was also uncertain. He thought that if they were really facing a desperate situation, there might be other options that would work.

Moreover, if this hot air balloon tactic proves effective, it can be used extensively in the future.

Therefore, the manufacturing method and principle he provided were merely imagined.

Fortunately, fate was on his side.

His knowledge was not too far off.

After flying a considerable distance, they managed to reduce firepower and land the hot air balloon smoothly...

Moreover, through this test flight, Yan Jia and his team discovered a truly remarkable place.

This hot air balloon can rise to a very high place; they estimated that it's beyond the reach of ordinary arrows.

Of course, it wouldn't be good if you didn't know when artillery was coming to bombard you.

However, they were well aware that the artillery was not fired in a direct line.

They believed that hitting them wouldn't be easy either.

If we're talking about shortcomings, there's one right now: the inability to control the direction.

Moreover, after flying too high, it takes time to land, so an instantaneous descent is not possible.

This adds difficulty to their operation.

Moreover, if they wanted to use hot air balloons to attack the Slavic armies, they would still have to rely on the weather.

If the wind direction is wrong or the timing is wrong, it will all be in vain!

However, Yan Jia wasn't in a hurry, since their advance wasn't fast anyway.

If this approach doesn't work, another one should be useful.

After Yunqing Urgen returned, he immediately led all the subdued Slavic prisoners through the tunnel.

Of course, they also dispatched some people from the Underworld to better control the situation.

Heaven was also very kind to them; Wei Wuji and his men had been waiting for half a day when the prisoners arrived.

Just as Wei Wuji understood what was happening, the scouts announced that the Slavic people who were transporting supplies had arrived.

They let the prisoners take over.

They also had some of Wei Wuji's men accompany them, providing double insurance.

Since Slavs look similar, the transport workers also heard that Saleh's campaign had been very successful.

Although they saw people from the Xiao Kingdom in the group, the prisoners said that those were Xiao Kingdom people they had captured.

It was used to help them do hard labor.

Those who transported the weapons had no suspicions.

Everything went exceptionally smoothly, even beyond Wei Wuji's expectations.

In fact, the reason why it went so smoothly was that they did not expect that the Slavs would be captured, let alone that these Slavic prisoners would be tamed and obey them obediently!
