Go and capture those thirty-six fierce villains.

They followed the attendants all the way to the outside of Prince Su's residence.

As far as the eye could see, Huang Mu was wearing a brightly colored robe and was looking around, shaking his head. The little yellow beast on his shoulder was standing upright.

"Brother Guiyuan!"

The other person greeted him from afar, rubbing his hands together somewhat awkwardly, looking quite embarrassed.

Qin Ning thanked the attendant who had led the way in a low voice, then walked to Huang Mu's side: "Brother Huang, it's been a while. What brings you here today?"

He hadn't seen the person since the last time he saw him sleeping anywhere.

With the Sichen Guard hanging like a sword over his head, Qin Ning had no time to think and dared not step out of the Prince Su's residence.

"Ahem..." Huang Mu looked around to make sure no one was around before leaning closer and whispering, "My family sent me to pick you up and take you back to our Sichen Guard."

Huang Mu is now in a very awkward situation. On that day, he was hiding in his room when he saw Qin Ning beating up Doctor Dong in the courtyard. His heart was pounding with excitement.

During a covert mission, I never expected to run into the target that the whole state was searching for. It was like a pie falling from the sky!

No, it's like a pre-chewed pie falling from the sky, the kind that just falls right into your mouth.

He immediately went up to greet them, struck up a conversation, and then sent the message out through his connections the next day.

Therefore, Huang Mu received a reward of three hundred taels of silver, as well as the cultivation method to advance to the seventh rank of acupuncture.

But who knew that just a few days later, the person he had reported suddenly became a colleague, and he even had to personally escort him...

Huang Mu had a vague feeling that he might have offended someone.

Moreover, this person must have a very powerful background.

You little brat, you're an undercover agent!

Qin Ning was surprised, and a strange look flashed in her eyes. So she had been exposed the moment she entered the inner city of the Prince's Palace that day. The Sichen Guard really was omnipresent.

He didn't reply, just stared silently until Huang Mu's hands were practically rubbing together until sparks flew, then Qin Ning whispered:

"Lead the way."

After leaving the inner city of the Prince's Palace, in the eastern part of Beian City, in a complex alleyway, Qin Ning followed the other party into an ordinary-looking house.

The house wasn't big. In the courtyard, an old man was lying on a bench, leisurely, with a palm-leaf fan in his hand.

This person must have known Huang Mu or was aware of the purpose of his trip, but after glancing at the two of them, he ignored them.

Huang Mu arrived at the dry well in the courtyard: "Brother Qin, please jump into the well."

Qin Ning: "Are you serious?"

"Ahem, this is indeed the route we usually take back to our base." Seeing Qin Ning's doubts, Huang Mu jumped directly into the dark well opening to set an example.

A moment later, Huang Mu's slightly ethereal voice came from down the well: "Brother Qin, come down here~"

I don't want to go down... Qin Ning pinched his nose and jumped down. The bottom of the well was not as confined as he had imagined; in fact, it was quite open and dry.

Looking around, there are eight roads leading in all directions, making it a small transportation hub.

"Brother Qin, remember this: these eight paths rotate every month. On ordinary days, seven of them are dead ends that are deceptive. Only the paths marked with hidden patterns are the paths to survival this month."

"If an spies going out want to use this secret passage, they need to get information from another place beforehand. The person in the courtyard is only responsible for guarding it and knows nothing about it."

Huang Mu gave instructions, took out a piece of fluorite that emitted a purple-blue light from his waist, and walked in front of each of the eight roads. "The traps and deadly moves in the roads are far beyond what doctors like you and me can handle. The one who came to Beian City with me back then got lost because of his bad memory. It should have been three months by now."

Huang Mu sighed, holding the fluorite in his hand directly above the road, which illuminated animals such as rabbits, mice, and chickens.

"Would that be considered a work-related injury?"

"Ah... I didn't ask about that, but I heard that his compensation was quite high. However, since the man had no family, it was all confiscated and used to purchase the weapons that killed him."

"What? Buy your own bullets...?" Qin Ning's lips twitched. He saw Huang Mu stop in front of a road with a picture of a blackfish drawn above it: "This is it, Brother Qin, let's go."

After Huang Mu finished speaking, he put away the fluorite in his hand, strode closer, and after walking for a while, he turned back and stopped, only to find that Qin Ning had not followed.

"Brother Guiyuan, there is a Lord [Muku] waiting for us at the camp. Hurry up."

Seeing that the other person had walked for a while without any problems, Qin Ning then followed, calling out, "Lord Mu Ku?"

"This is the internal job classification system of my department. You will be given an explanatory document after you join, but I can explain it to you first."

Huang Mu slowed down, maintaining a pace that was half a body length ahead of Qin Ning.

"A cool breeze rises, cicadas chirp, grass and trees wither, frost falls. This nursery rhyme is the rank division of our Sichen Guard's Autumn Department."

Huang Mu led Qin Ning for a while, and then they came to a wide-open transportation hub. As usual, he took out the fluorite to look for the dark patterns, and kept saying, "The Liangfeng rank is the lowest, divided into 1 to 7 levels. I am currently a third-level Liangfeng Guard. If I make two more minor merits, I can be promoted to first level. At that time, I will be promoted to the seventh rank. If I make one more medium merit, I will be a seventh-level Hanchan Guard."

"Above that is the withered wood, and I guess I have no hope in this lifetime. As for the legendary 'Frost's Descent,' I heard that there are only five of them in the entire autumn season."

Cool breeze, cicadas chirping, withered trees, frost... What rank does Xu Meishan hold?

After navigating this vast and complex underground network for a long time, Qin Ning and his companion finally began to ascend.

There are such a huge underground passage in Bei'an City... I wonder if the Prince Su's mansion is unaware of it, or if they are pretending not to see it.

"Brother Qin, we've arrived."

Huang Mu stood on an upward slope, raised his hand and placed the fluorite in his hand into the groove of the stone slab above his head. After a moment, with a slight friction sound, the two stone slabs slowly opened, and the sunlight outside shone in.

The two exited the secret passage. Qin Ning looked around and found that it was an empty room, and it was quiet outside the door.

Huang Mu went over and opened the door, exchanged a few pleasantries with the two guards outside, and then turned to greet Qin Ning.

Stepping out of the room, he glanced around and discovered that the two guards at the door were actually twins, except that one had big eyes and the other had small eyes, so their appearances didn't look quite alike.

"The adults are waiting for you in the back room."

The two guards spoke in unison, their voices weak and listless, as if they had no spirits.

.......

The back hall of the Sichen Guard's residence.

Huang Mu escorted Qin Ning to the door and then politely withdrew.

Upon entering, the room was dimly lit and no lights were on.

The first thing Qin Ning saw was a bald, burly man with a face full of scars. He was dressed in a yellowish-green robe with seven withered leaves embroidered on his chest. He looked fierce and menacing, but at that moment, one of his arms was covered by a white cloth and hung down in front of his chest.

It somewhat ruined his image of someone who clearly wasn't a good person.

"Alright, you've identified the person. Now you can leave... cough cough."

Xu Meishan, who was sitting in the chair, coughed lightly and gave the bald man a look.

"Yes, sir!"

The fierce-looking man's expression instantly turned respectful. He obediently walked out of the house, his triangular eyes still scrutinizing Qin Ning as he passed by.

His eyes were mostly filled with curiosity, but also with a hint of apprehension and suspicion.

squeak~

The door was closed, making the already dim room even darker.

"Couldn't you just light a candle?" Qin Ning took two steps forward. Xu Meishan opened his mouth as if to say something, but what came out was a violent cough.

"Cough cough cough cough!"

Clang!

A gear that was neither gold nor wood was coughed up from his throat.
