With a warehouse full of supplies, I stood alone as king in this chaotic world, gun in hand.

The Ministry of Revenue's treasury was located on the east side of the imperial city, surrounded by high walls and heavily guarded.

Nangong Wu and Beichen Yan stood on the highest roof ridge, using night vision binoculars to observe the situation inside the Ministry of Revenue.

The security inside was far more stringent than that of the imperial palace.

"How is it?" Bei Chenyan asked her.

"Since we're here, we might as well give it a shot." Nangong Wu put away her binoculars. "You wait outside, I'll go in alone."

She has a spatial dimension, which she can use to hide in if she encounters danger.

Bei Chenyan looked at her intently, then suddenly picked her up and flew away.

After a while, he stopped.

Nangong Wu looked around and realized that she had arrived at the wall of the Ministry of Revenue.

Bei Chenyan whispered in her ear, "Wait a moment."

Nangong Wu stood still, watching to see what he wanted to do.

Bei Chenyan turned his back, covered his mouth with both hands, and emitted three chirping sounds—one long and two short.

"Coo...coo coo..."

After waiting for a while, in the dim light emanating from the Ministry of Revenue, a figure appeared, crouching low and sneaking towards them.

But they stopped when they were about ten feet away from them.

"Cao Li," Bei Chenyan called out softly.

Upon hearing his voice, the person immediately approached, "You..."

Bei Chenyan raised his hand slightly and whispered, "We want to get into the Ministry of Revenue's treasury. Do you have a way?"

Cao Li's expression turned serious. "A month ago, the Ministry of Revenue dispatched another 5,000 Imperial Guards, and it's said there are also over a hundred people from the Northern Region. It will be very difficult to get in."

Bei Chenyan frowned as well. "Is there any other way?"

"There is another way, why don't you take a look first? If it still doesn't work, we can think of another way tomorrow," Cao Lixian said.

"Okay, let's go take a look first." Bei Chenyan nodded.

Cao Li surveyed the surroundings, then crouched down and walked ahead, saying, "Please follow me."

Nangong Wu was taken aback by their words. How could Bei Chenyan have managed to place someone in the Ministry of Revenue of the Eastern Jin Dynasty?

Who exactly is this man? Why do so many people follow him?

"Let's follow." Seeing that she was still standing still, Bei Chenyan took her hand and followed Cao Li.

Cao Li led them along the wall, and then they moved further and further away from the Ministry of Revenue.

Bei Chenyan didn't ask any questions and followed Nangong Wu into a small alley.

After walking for about half an hour, Cao Li, who was ahead, stopped in front of a house.

Even Bei Chenyan looked puzzled.

Cao Li looked around the dark and quiet alley, and after confirming that no one was there, he knocked on the courtyard gate.

A moment later, they heard footsteps approaching from inside.

The courtyard gate was opened, and a head peeked out.

It was an old man with gray hair, carrying a lantern in his hand. When he saw that the person knocking on the door was Cao Li, he was stunned for a moment, but he didn't say anything and opened the courtyard gate to let them in.

After the three of them entered the courtyard, Cao Li took the lantern from the old man's hand. "Uncle Wu, please go back inside and rest!"

"Yes," the old man replied, without daring to look up.

Cao Li carried the lantern and walked inside, passing through the hanging flower gate and the covered corridor to the backyard.

Nangong Wu glanced inside and saw that the gate was very ordinary, but it was a large courtyard with three sections.

Cao Li stopped in front of a small house, took a key from a flowerpot next to him, and opened the door.

Cao Li went into the house, closed the door again, put down the lantern in his hand, took out a piece of paper from his pocket, unfolded it, and spread it on the table.

Nangong Wu and Beichen Yan looked at it and saw that it was a map, so they both came over to take a look.

"Where is this map from?"

"This is the underground passage I mentioned to you before." Cao Li pointed to a line on the map:

"This secret passage was originally left by the emperor of the Eastern Jin Dynasty. It leads from the palace to the outside of the imperial city and happens to lead to the underground treasury of the Ministry of Revenue."

"That's great!" Nangong Wu didn't expect Bei Chenyan's people to be so helpful.

"This secret passage has been abandoned for over a hundred years. After I found it, I went down to check and found that some parts had collapsed, but it was still barely passable."

The end of the secret passage had been blocked. Later, my subordinates discovered that the secret passage was only half a mile away from the Ministry of Revenue's underground treasury, so they spent a lot of money to buy this house. The secret passage was right under our feet.

After his subordinates dug the secret passage, they spent over a year digging an underground silver vault leading to the Ministry of Revenue. However, the walls of the vault were entirely constructed of the hardest quartz, making it extremely difficult to pry open.

Upon hearing this, Nangong Wu and Beichen Yan exchanged a glance.

She has such powerful explosives that she can blast open even the hardest rocks.

"Where is the entrance? Let's go down and take a look," Bei Chenyan asked.

Cao Li put the map away and back in his pocket. He then walked to a vase and turned it around.

With a loud "boom," a hidden passageway was revealed in the ground against the wall.

Cao Li picked up the lantern again and went down into the secret passage. "Please come with me."

Nangong Wu took out two small flashlights, giving one to Bei Chenyan, saying, "This is for you. If it goes out, come find me."

"Thank you." Bei Chenyan took the flashlight, clearly delighted with it.

"Go down." Nangong Wu was the second to go down the secret passage, and a musty smell hit her face.

She turned on her flashlight and saw that the dark passage was square, with bluestone slabs paving the ground, walls, and ceiling. No wonder it hadn't collapsed for over a hundred years.

"It's more than a mile from here to the Ministry of Revenue's treasury, so watch your step," Cao Li instructed before leading the way.

He walked very fast and soon stopped at a bend in the road.

"This road was dug by my subordinates, and it is about twenty zhang long."

When Nangong Wu and Beichen Yan shone their flashlights, they saw that the tunnel was indeed newly dug, but it wasn't that wide.

They reached the end of the secret passage, where a stone wall blocked their way.

"Behind this stone wall is the Ministry of Revenue's underground treasury." Cao Li tapped the stone wall, looking troubled. "This is a rare quartzite. I heard from them that it is five feet thick and extremely hard. I have tried many methods, but I have been unable to pry it open."

"What do you think?" Bei Chenyan asked Nangong Wu.

"Let's blow it up now," Nangong Wu said.

"Alright." Bei Chenyan nodded and instructed Cao Li, "Go up now and don't go back to the Ministry of Revenue. Take Wu Bo with you and leave here. Go find Lao Fei; he will take care of things for you."

Cao Li's expression was grave. "You..."

"We'll be fine." Bei Chenyan waved his hand at him, his tone becoming more serious. "The capital city will be in chaos soon. You must leave immediately. No matter what happens tonight, don't get involved. Protect yourselves."

"The other end of this secret passage leads to the outside of the imperial city. Since we are leaving, I will take Wu Bo directly out of the city," Cao Li said.

If something happens here, the city will definitely be locked down and everyone will be searched tomorrow, making it difficult for them to leave.

Bei Chenyan nodded, "Okay, I'll go back and have Zhang Qing meet you."

"Yes." Cao Li cupped his hands in greeting. "Then I'll go up first."

After saying that, he picked up the lantern, turned around, and hurried away.
