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

"So that's how it is..."

Hearing Lin Heng say this, Gesang Nazha recalled the words Xia Feng had left behind before he departed.

Although it seemed like a casual remark, it was indeed as his master had said; he had not truly let his guard down.

After all, the Sand Fox family used to run a business selling fairy slaves, and Gesang Nazha, as the eldest daughter of the family patriarch, was well aware of this.

The trust between a celestial servant and his master is often built on the foundation of the servant's spirit seal...

The heavy rain continued throughout the morning without any sign of stopping.

With nothing else to do, Lin Heng spent the whole morning staring at Mu Tinglan's Q&A desk.

I watched helplessly as the 2% unlock progress increased to 21%...

After lunch, Mu Tinglan returned to her dormitory to continue reading, while Song Jingyu went to the Fiery Camp.

Gesang Nazha and Yun Qinghe went to the bathing room.

One person is practicing swordplay, while another is leaning against the window of the shower room, lost in thought...

Lin Heng, meanwhile, sat alone at the table, pondering whether he should continue staying at the Zaxi Pass.

After all, his real purpose in coming to Zaxi Pass was still Yunma Snow Mountain...

"Little teacher, little teacher!"

Not long after, Tian Qianchen braved the rain and came to Lin Heng's courtyard from outside.

"Elder Tian, ​​what brings you here?"

Lin Heng got up and opened the door, gesturing for him to come in. "It's raining today, so I can tell you some knowledge about array construction."

"Formation?!"

Tian Qianchen's eyes lit up, then he frowned somewhat hesitantly and said, "Never mind... Little teacher, let me tell you the important matter first!"

"Is it serious business?"

"Um!"

Tian Qianchen nodded heavily and then cautiously looked around.

Lin Heng said helplessly, "This is an oasis in the clouds."

"Oh, right..."

The oasis in the clouds is full of Lin Heng's people.

Even if it's something that shouldn't be heard by others, as long as Lin Heng doesn't allow it, no one will talk about it.

Tian Qianchen cut to the chase, saying, "It's like this, after we finished discussing the cooperation yesterday, didn't you go out with Langbu from the Ando Sheep Clan?"

"Um."

Lin Heng nodded.

"Later, Sangjie of the Jiali cattle tribe also went out...and then that guy surnamed Bao found me!"

Tian Qianchen stared at Lin Heng with a serious expression.

"Elder Bao?" Lin Heng asked, somewhat surprised.

"Um."

Tian Qianchen immediately nodded and said, "That old guy came clean with me when no one was around. He said that the original excavation plan never intended for us to collaborate with you, Little Teacher!"

"Um."

Lin Heng nodded slightly, not at all surprised.

Actually, he found it a bit strange when he was invited to discuss cooperation from the beginning.

For the Jiali cattle tribe and the Ando sheep tribe, digging was taking place on their own territory, so cooperation between the Chief Administrator and them was inevitable.

Although I did provide Gale Grass to speed up the excavation process in this collaboration...

But to share the underground treasure just to excavate faster seems like a really bad deal.

So when Bao Haifeng mentioned the Gale Grass yesterday, Lin Heng felt much like he had just descended from the Cloud Oasis and been surrounded by a group of Ando sheep tribe members wielding magic scrolls.

I hadn't thought about it in detail before, simply because there was something Lin Heng wasn't quite sure about...

"He was actually testing you, junior teacher."

Tian Qianchen said to Lin Heng somewhat awkwardly.

After all, Bao Haifeng, like him, was an elder of the General Administration Division.

"What was he testing me for?"

And this is the only thing Lin Heng is unsure about.

If you're going to test someone, you should at least have a purpose in doing so.

For example, the Ando sheep tribe's probing was clearly a response to the Sand Fox family, who to some extent represented them and were competing with them for territory.

But what exactly is Bao Haifeng from the General Headquarters testing?

Tian Qianchen said seriously, "Regarding your resources, Little Teacher... his request for Gale Grass is an attempt to test whether your territory contains many spiritual herbs, as Tao Hongzhou reported."

"Does he need a magical herb?"

"Spirit herbs... are actually only part of the resources. What that guy really wants is your ore, little teacher!"

After taking a deep breath, Tian Qianchen continued, "Back in Golden Deer City, didn't you suggest exchanging a large amount of ore for the Spirit Restoration Array?"

"Um."

Lin Heng nodded.

Tian Qianchen rubbed his hands together sheepishly and said, "Back then, the Emperor used the power of the entire nation to collect the ores on your list, little teacher... and the collection methods also included the cooperation that Bao Haifeng had originally agreed upon with a mine."

Lin Heng said thoughtfully, "So you mean to say that some of the ore Elder Tao brought me last time was originally intended for Elder Bao to buy?"

"right!"

Tian Qianchen immediately said, "That old guy reacted very strongly back then. He even went to the Imperial Palace to ask the Emperor to leave the ore he needed, but... Little Teacher, your Spirit Restoration Array is related to the Princess's awakening, so naturally it was rejected by the capital. I heard that because of this, he smashed all the cups in his house..."

"What does he want those ores for?" Lin Heng asked again.

"Form a formation!"

Tian Qianchen almost blurted out, "Although that old guy Tao Hongzhou has the highest level of array construction in our General Administration Division, he can only learn some basic array construction from the Chaos Demon Lord's manual and cannot completely replicate it."

"But Bao Haifeng is different. His research is not as comprehensive as Tao Hongzhou's. He just focuses on one of the array structures."

"The ores he purchased earlier were the materials he originally intended to use to replicate that array."

"According to those old guys in the General Headquarters, he seems quite confident in replicating the summoning array from the Chaos Demon Lord's Manual..."

Lin Heng nodded thoughtfully: "A summoning-type array?"

"Hmm, this old fellow is obsessed with summoning-type array construction; his small courtyard at the General Headquarters is filled with forest guards..."

After a pause, Tian Qianchen said, "Of course, his forest guardian isn't as powerful as the one you constructed, Teacher, and it doesn't have a self-healing effect... Oh, right!"

Suddenly, as if remembering something, he asked Lin Heng, "Little teacher, do you still remember Cao He from Linxian City?"

"certainly."

Lin Heng nodded.

Tian Qianchen stroked his beard and recalled, "I remember a few years ago, Cao He traded some ores from Linxian City for one of his arrays. I heard it was a prototype he used to replicate that array..."

"Cao He's formation?"

and many more!

Suddenly, Lin Heng paused for a moment.

Upon hearing this, Tian Qianchen recalled that there was a summoning array placed in the garden leading to the underground passage in the City Lord's Mansion of Linxian City.

When he brought the Thousand Branches Vine Sword and Song Jingyu out of the cave, he even dismantled the array.

Lin Heng was quite surprised at the time.

How did Cao He obtain such an array capable of summoning a demonic tide...?
