After the destruction of the Immortal Realm, I took in the fallen fairy.

Knock knock knock.

After the carriages from the Mystery Mine passed through the bustling city center and then through Dawn Square.

A group of about ten people dressed in plain white clothes passed by in neat rows on both sides and jogged in front of the carriage.

"Damn it, what is that old hag Aunt Xue doing?"

Shen Zu lifted the curtain of the carriage and immediately recognized the owners behind these people.

After all, his business has a deep partnership with Wangchen Book Gallery.

And judging from the direction these people were running, they were heading towards the northern suburbs where their mine was located.

"Boss!"

Soon, a servant from the Xuanji Mine came to report to Shen Zu: "Aunt Xue sent word that Wangchen Book Gallery is going to take some minerals from the mine tonight to make small spirit books."

"The trading day for this month hasn't started yet, why has it suddenly been moved up to today?"

Shen Zu snorted unhappily.

However, he didn't openly break off relations. He simply beckoned to his subordinates: "Arrange the people from the Forgotten Dust Library at the east gate of the mine, and activate the hidden magic array."

"Yes, boss."

The subordinate left.

Shen Zu also pulled the carriage curtain shut and snorted unhappily.

"There are concealment formations at the East Gate, and perhaps also offensive formations. Try to avoid them when you go there."

"Yes, Master."

At the same time, Lin Heng also conveyed this information to Mu Tinglan through Liuhun Yuji's ability.

"Hehe, young friend Lin Heng, please don't mind. This is just a routine collaboration between our Xuanji Mine and Wangchen Book Gallery."

Turning his head, Shen Zu also smiled and explained the situation to Lin Heng.

He didn't hide anything from Lin Heng, because it had nothing to do with the work he was about to do.

After all, for Xuanji Mine, these are all businesses that can be openly discussed.

Therefore, Shen Zu not only wouldn't hide it from Lin Heng, but would also use it to show his strength to the other party: "After all, Aunt Xue needs to use some special ores from our mine to make the formation for the Little Spirit Book."

"Yeah?"

Lin Heng asked curiously, "Does Aunt Xue at Wangchen Bookstore make the little spirit books herself?"

"Yes, and this is the only formation she knows."

Shen Zu nodded and said, "Speaking of which, that woman has quite a business mind. I never expected that such a simple magic array could make her one of the wealthiest merchants in Golden Deer City. Back then, Aunt Xue was just an ordinary writer."

"Did Aunt Xue write books before?" Lin Heng asked in surprise.

"Yes, I retired from the Capital Commandery."

Shen Zu chatted with Lin Heng: "Although her work at the General Administration was not as good as Elder Tian's, whom you know well, she was still a fairly well-known writer. Almost all the history books about the 50th year of the Demon Calendar that you can find in other cities were written by her..."

Lin Heng nodded slowly.

Although this information did not help with tonight's actions, it did make him a little more familiar with Aunt Xue of Wangchen Book Gallery.

……

Chatting along the way, the carriage officially left the urban area of ​​Jinlu City and arrived at the northern suburbs.

Looking out the carriage window, Lin Heng discovered that the mining area was much larger than he had imagined.

There are few houses and buildings here, making the open land seem even more spacious.

Its area is at least half the size of Linxian City, and even comparable to the size of the Oasis in the Clouds.

On this mine site, there are many large tents still lit by oil lamps.

In the pitch-black night.

Lin Heng could clearly see the shops near the tent through the dim light.

They sell goods such as grain and clothing.

Clearly, for the miners at Xuanji Mine, this is where they truly live.

The prosperity of Jinlu City has nothing to do with them.

However, apart from a few unkempt miners passing by on the road, I hardly saw anyone else.

This contrasts somewhat with the scene of tents lit by oil lamps and shops in operation.

After all, this is the time when miners should be finishing their mining work and starting their daily lives.

But at this moment, Lin Heng did not feel a strong sense of life.

"Master, I... saw many celestial slaves who had been bound by the Slave Spirit Seal, as well as celestial maidens who had not yet been bound by the Slave Spirit Seal."

Suddenly, Mu Tinglan's voice echoed in her mind.

"Where?" Lin Heng asked.

"Judging from the direction your carriage is traveling, you shouldn't have noticed."

Mu Tinglan said in a deep voice, "They are located exactly to the east of what you just mentioned, Master. They are gathered in two mines that have been completed and are heavily guarded at the entrances."

Clearly, these celestial servants and fairies were arranged by Shen Zu in advance, deliberately kept from Lin Heng's notice.

"Moreover, these celestial servants and fairies all have one thing in common."

Mu Tinglan took a deep breath and continued to Lin Heng, "They either have fire spirit roots, or... like me, they have water spirit roots."

"The fairy slave with the water elemental root was covered in pustules, and it looked like he had been poisoned."

Lin Heng nodded slowly.

This does correspond to the information Yun Yue brought earlier.

The Water Spirit Root Fairy's value to Shen Zu lay in her ability to forcibly stimulate the characteristics of his spiritual root through spirit stones, thus purifying the poisonous filth in his mine.

"etc."

At this moment, Mu Tinglan said with some surprise, "The fire spirit root fairy named Liu Xiyue, whom we met on our first day in Golden Deer City, is also among them, but..."

"Just what?"

"Her lips were ulcerated from drinking mineral water for a long time, and her spiritual roots were damaged beyond recognition. She was almost unrecognizable from the person we saw back then."

After a pause, Mu Tinglan said in a deep voice, "And right now, she's standing at the entrance of the miners' tents, surrounded by several miners, and they're... "

Before she could finish speaking, Lin Heng had already guessed what had happened on Liu Xiyue's side.

The reason why Shen Zu hid those fairies and fairy servants was because...

It's probably also to prevent the secrets of Golden Deer City from being discovered by themselves...

"Young friend Lin Heng, this is the place."

At this moment, the carriage stopped, and Shen Zu smiled and invited Lin Heng to get out of the carriage.

"We've arrived. Let's not linger there any longer."

At the same time, Lin Heng also gave instructions to Mu Tinglan.

"Yes, Master."

Mu Tinglan pursed her lips and instructed the fire spirit root fairies beside her to carefully follow Lin Heng.

"Oh, right."

Suddenly, Lin Heng's voice came from Mu Tinglan's heart again.

Because from beginning to end, he could clearly sense Mu Tinglan's tension.

Even though it was just through the connection established in their hearts by Liu Hun Yu Ji, Lin Heng could clearly feel a tremor that was different from usual when he heard Mu Ting Lan's thoughts.

"Master, is there...anything else planned?"

"This operation is very important, but don't be too nervous. Being too nervous can sometimes lead to the opposite of what you want."

Mu Tinglan paused for a moment, then said, "Yes, thank you for your concern, Master..."
