The government was sending out wives, and I ended up with a princess from the previous dynasty!

"Huh! Huh!"

"Whoosh! Whoosh!"

Jia Daoshi's Peacock Feather weapon can be used for pinpoint shots, making it ideal for surprise attacks.

Weng Changting, who was standing to the side, had never seen this thing before, and it was not recorded in the "Overbearing Mechanical Techniques".

This made her very curious.

Actually, there were many things in "The Overbearing Techniques" that she didn't quite understand.

Unfortunately, her mind wasn't actually geared towards engineering; it was more inclined towards the humanities.

Therefore, I am somewhat sentimental.

What is this in your hand?

Seeing that Jia Daoshi had silently and efficiently dealt with the guards in the backyard, Weng Changting finally couldn't help but ask.

"This is called a peacock feather, isn't it awesome?"

Jia Daoshi chuckled.

What is awesome?

Weng Changting felt that these two words did not sound like a good thing.

"It means very powerful," Jia Daoshi explained.

“Um…indeed…impressive…” Weng Changting didn’t know what to say.

“Want to learn? I’ll teach you!” Jia Daoshi winked at Weng Changting.

Weng Changting suddenly felt like she'd been electrocuted, but she still stubbornly insisted, "I won't learn it!"

"No rush, where do we go next?"

Weng Changting pointed towards the tool shed: "Follow me."

Soon, the two entered a room.

The tool shed was indeed a tool shed, filled with all sorts of tools.

Weng Changting walked to a cabinet: "This is the place."

Jia Daoshi stepped forward and moved the cabinet aside, discovering a downward passage inside. Above the passage was a groove filled with kerosene, and on the kerosene was a thick rush wick.

"Shall we light it now?" Weng Changting asked.

Jia Daoshi glanced back at Weng Changting and nodded, saying, "After lighting the fire, we'll immediately return to the passage we just came from."

“We have about ninety breaths to escape, so there’s no problem with the time,” Weng Changting nodded.

During the initial design phase, many oil bombs were secretly hidden beneath the foundation of the city lord's mansion and at key points in the city wall. These bombs were connected together by a rush vine about the thickness of an arm.

If it's ignited here, the entire Sifang City will be engulfed in a series of explosions!

Let alone the city lord's mansion, even the indestructible city walls would be blown to bits!

This is what makes the master architects of the Deadwood School so remarkable!

They can bring good, and they can bring destruction!

If Sifang City is driven to the brink of destruction, what will be left for the enemy is a pile of rubble, not an impregnable fortress.

This also reveals Kuang Qianqiu's foresight and his disappointment with the Daqing court.

After lighting the fuse, the safest way is to hide in the newly emerged artificial hill passage and sneak out of the city by water.

However, the explosion at the City Lord's Mansion may cause tremors throughout the entire underground of Sifang City.

There is a certain probability that the passage will collapse.

But this was not a difficult task for Jia Daoshi.

Anyway, he practiced the Dragon Elephant Divine Skill.

"Alright, time to ignite the fire. Let's prepare to retreat."

Jia Daoshi took out a lighter.

"Clap!"

A small flame flickered.

"And what is this?" Weng Changting was dumbfounded; he had never seen a fire starter like this before!

"This is called a lighter. I'll explain it to you later."

Jia Daoshi lit the fuse, and a blue flame rapidly spread within the groove!

"go!"

Jia Daoshi and Weng Changting left the tool shed and quickly returned to the artificial hill they had just been at.

Just then, a patrol of soldiers spotted the two and shouted sternly, "Who's there!"

Jia Daoshi pulled out the Peacock Feather and fired directly!

"Shhhhhhh!"

"Pfft! Pfft! Pfft! Pfft!"

A patrol of soldiers was instantly wiped out!

Soon, the two ran back to the artificial hill and plunged into the passageway.

The passage was dark, but thankfully there was the luminous pearl on Weng Changting's chest.

"one two Three……"

Jia Daoshi silently counted in his mind.

"boom!"

When the count reached twenty, the spark from the fuse reached the location of the first incendiary bomb, and the first massive explosion occurred!

There was a huge commotion!

Even underground, you can feel the earth shaking above!

The soil fell softly from Jia Daoshi and Weng Changting's heads.

"Come on!"

Jia Daoshi grabbed Weng Changting's small hand and quickened his pace.

Being led by Jia Daoshi like this, Weng Changting felt inexplicably at ease.

……

At this moment, hundreds of small boats on the river, their sails billowing in the wind, had reached a position very close to Sifang City.

The ship stopped.

The 20,000 elite troops remained silent.

At this time, the city walls of Sifang City were already faintly visible.

"Your Highness, what should we do now?"

Lan Biyin hesitated for a moment, then asked.

"Wait."

Shen Li uttered a single word calmly.

Time passed slowly, and groups of torches occasionally passed by on the walls of Sifang City, but none of them spotted the Zhenbei Legion on the river.

As the snow piled up on her body grew thicker, Shen Li began to grow impatient.

"Did I fail? Did this guy trick me?"

Just as this thought arose!

"boom!"

A deafening sound rang out!

At the same time, a towering flame suddenly blazed up inside the city, almost turning half of the night sky red!

"What's going on? How come there's such a big fire inside Sifang City? Wasn't it said that all the spies that the Prince placed there have been killed by Murong Nishang?" Lan Biyin asked with a puzzled look.

"The teacher must have succeeded!" Shen Li's spirits lifted!

"What? You're saying Mr. Jia is inside? He did this?" Lan Biyin was shocked.

How could one person cause such a commotion?

Isn't this incredible?

"Can we attack now?" Lan Biyin looked at the chaotic Sifang City walls and began to rub her hands together in anticipation.

"Wait a little longer," Shen Li shook her head.

"Still waiting? Okay, let's wait."

Sure enough, not long after, a series of explosions rang out!

"Boom! Boom! Boom!"

This time, the explosion was much clearer, and it actually came from the city wall!

What Lan Biyin had initially considered an impregnable fortress was now collapsing like dominoes!

The flames that ignited swept across the entire night sky!

Screams echoed far, far away in the darkness!

"What's going on? Why have all the city walls of Sifang City collapsed?"

"The Thousand Rock Army is too ruthless; they even blew themselves up!"

"What's going on? Something's not right!"

"Your Majesty!"

Lan Biyin was also shocked.

They had tried so hard and suffered heavy losses before, but they still couldn't take it down. Now, the people of Longwu Kingdom have blown down the city walls themselves!

What does this mean?

Watching the boulders roll onto the ice, smashing holes in it, and the Thousand Rock Army soldiers being blown to pieces, some even jumping into the water with flames still on their bodies, the Zhenbei Army was completely dumbfounded!

"Hahaha! Your Highness, Heaven is on our side! We can attack now!"

Lan Biyin laughed heartily!
