Every time the prince opens his eyes, he sees

"A little closer?" Xie Qingchen curled his lips. "Are you hoping that I'll be discovered by the Beirong soldiers, and then blow me to pieces with their new weapons?"

"Your Highness, I believe in you." Lu Yaoyao blurted out.

She didn't mean to flatter Xie Qingchen on purpose in order to get what she wanted.

But she and Xie Qingchen have been together day and night for many years, and she is quite familiar with his strength.

There are not even five people in the entire Dajin who have the same skills as Xie Qingchen.

"Okay, if they find me, you'll die with me!"

There was a barely perceptible madness on the corner of Xie Qingchen's mouth. He patted the horse's back lightly. The Arabian horse seemed to understand its master's mind and turned and ran into a hidden place. Xie Qingchen hugged Lu Yaoyao and slowly approached the city wall with his lightness skills.

Xie Qingchen's movements were so light and his figure so elusive that the guards on the city wall didn't even notice anyone approaching.

As the distance got closer, Lu Yaoyao could see the full picture of those new weapons more clearly.

They are huge in size and composed of complex mechanical structures, with their muzzles pointing straight to the sky, as if they can spit out flames that can destroy everything at any time.

She secretly calculated in her mind that although these weapons were powerful, they must also have their weaknesses. As long as she could find that key point, she would be able to find a way to restrain them.

"Your Highness, look at these weapons. Although they have powerful firepower, they seem to be able to hold very little ammunition. After each shot, it takes a certain amount of time to reload and adjust." Lu Yaoyao observed carefully for a while and analyzed in a low voice.

Xie Qingchen nodded slightly, a hint of approval flashing in his eyes. "Not bad, you have sharp observation skills and spotted their weaknesses so quickly. But even if you find them, it's useless. The real challenge lies in how we can avoid being discovered before we get close to them, and how we can destroy them before they launch and return. Otherwise, they will destroy us before we can destroy them."

"Furthermore, this weapon only needs to be mounted on a city wall to be used. If only a few people were left on the opposite city wall after being killed, ordinary soldiers would not be able to climb up, let alone destroy this weapon."

"I would like to venture to suggest that if we can use some device to interfere with their launch trajectory at the moment they are launched, perhaps we can reduce their lethality." Lu Yaoyao put forward her own idea based on Xie Qingchen's analysis.

Upon hearing this, Xie Qingchen's eyes flashed with surprise, which then turned into praise. "Your idea is very novel, but it will be extremely difficult to implement. However, I like challenging things. Go back and study it carefully, and we will discuss it in detail tomorrow."

"Yes, I will definitely live up to your expectations, Your Highness." Lu Yaoyao responded solemnly, already having a preliminary idea in mind.

The two returned to the military camp. It was already late at night, but Lu Yaoyao was not sleepy at all. She immediately immersed herself in her research.

She tapped the system and flipped through all the books the system could give her to find inspiration.

Finally, she combined her ideas with practice, drew detailed blueprints, and designed a device that could interfere with the firing trajectory of the artillery.

The next morning, when the first ray of sunlight penetrated the clouds and shone on the military camp, Lu Yaoyao had already arrived in front of Xie Qingchen's tent with her design drawings and full of excitement.

"Your Highness, I have something important to discuss with you." Her voice was filled with urgency.

"Come in." Soon, Xie Qingchen's voice was heard from the tent.

Lu Yaoyao lifted the tent and walked in.

"Has what you envisioned been made?" Xie Qingchen asked, his eyes falling on the drawing in her hand.

Lu Yaoyao nodded, slowly unfolded the drawing, and elaborated on her design ideas and implementation plan in detail.

Xie Qingchen listened attentively, nodded from time to time, with a gleam of approval in his eyes.

"This plan is feasible, but you need to be extremely careful when implementing it. You go and prepare, and I will dispatch a team of elite soldiers to cooperate with you." Xie Qingchen said cautiously.

"Yes, I will take my leave first."

After Lu Yaoyao left Xie Qingchen's tent, she immediately began to prepare.

Not only did she personally supervise the production of the device, but after the device was completed, she carefully selected ten smart and brave soldiers from the elite soldiers assigned to her by Xie Qingchen for training, ensuring that they could master the use of the device in the shortest time possible and become familiar with the route of action.

The device is named "cloud disruptor". It is cleverly designed to release a special smoke at the moment the artillery is fired, interfering with its aiming system and causing the shell to deviate from its original trajectory, thereby reducing its lethality.

At the same time, Xie Qingchen was also busy deploying a counterattack plan.

The "cloud disruptor" must be combined with other tactics to form a complete combat plan in order to play its greatest role.

Finally, on a windy and moonless night, Lu Yaoyao led a hundred elite soldiers, carrying a "cloud-disrupting device", and quietly approached the city wall of Beirong.

Their movements were swift and precise, like ghosts in the dark night, leaving the Beirong defenders unaware.

After they put the cloud-disrupting device in position, 30,000 elite soldiers led by Xie Qingchen, who were hiding in the dark, surged out from all directions of the city wall like a black tide and began to attack the city wall.

"They're launching a sneak attack. Dajin is launching a sneak attack."

The first Beirong soldier noticed something was wrong and hurriedly sounded the alarm.

Sharp explosions echoed throughout Beirong City.

The soldiers on the city wall immediately entered combat status.

The soldiers operating the artillery position were busy putting ammunition into the cannon.

Just as Beirong's artillery was about to fire, Lu Yaoyao gave an order and the soldiers quickly activated the "cloud disruptor".

Suddenly, a thick smoke spread out and enveloped the artillery position.

The muzzle flame flickered in the smoke, and the shell deviated from its original target and landed on an open space in the distance, leaving only a deafening roar.

The defenders of Beirong were stunned by this sudden change. They did not expect that Dajin would come up with such a strange trick to deal with their new weapons.

Taking advantage of their panic, Xie Qingchen personally led the army to launch a general attack.

The soldiers of the Great Jin were in high spirits, like a tiger descending from a mountain, unstoppable.

The battle lasted all night until the first rays of dawn appeared in the east.

In the end, the Jin Dynasty won the victory, and Yelu Qi was forced to retreat into the city with the remaining Beirong troops.

The new weapons they were so proud of also lost their former glory in this battle.

"We won, we won." I don't know who cheered first, and then more cheers rang out on the battlefield.

They couldn't believe that they could win the battle today after suffering many defeats in recent days and their morale was almost broken.

"Doctor Miaofeng is mighty, Doctor Miaofeng is mighty."

Lu Yaoyao was caught off guard and was thrown into the air by the soldiers.

The soldiers expressed their love for Lu Yaoyao in their most sincere way.
