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

The next day, early morning.

Lin Heng stepped out of the courtyard early in the morning and lazily stretched.

Nearby, the immortal servants who were building the Fiery Camp had already started work ahead of schedule.

Lin Heng took a box of stone bricks from the warehouse next door and then carried a wooden table from his house to the gate of the yard.

The prerequisite for setting up the Demon Detective Platform is that a table is required.

As Lin Heng placed the stone bricks one by one, the sun gradually rose higher in the sky.

Mu Tinglan had already gotten up to read, and after glancing at Lin Heng in the courtyard, Song Jingyu also began to obediently plant spirit herbs beside him.

Finally, Yun Qinghe came out and stood behind Lin Heng, somewhat at a loss, but she didn't bother him.

After all, once the Thousand Branches Vine Sword completely replaced her spirit stone, she was at a loss for what to do and could only stand blankly beside her master...

"Completed."

Suddenly, Lin Heng patted the dust off his hands and looked at the successfully constructed Demon Detector with satisfaction.

Turning around, he saw Yun Qinghe coming over, so he reached out and said, "Give me a spirit stone."

"Oh! Yes, Master."

Yun Qinghe immediately went back to the house and retrieved the spirit stone.

After receiving the spirit stone, Lin Heng carefully placed it into the core of the Demon Detective Platform.

Immediately, a wisp of spiritual energy floated above the Demon-Seeking Platform, forming a phantom-like and ethereal interface:

[The Demon Detective Altar is activated.]

[Next Demon Tide: 5 days from now.]

[Do you want to view the monster levels of past demonic tides? (Only records demonic tides after the construction of the Resurrection Array, and requires changing the array construction rules of the Demon Appraisal Platform)]

Can I also view the level of the previous demonic tide?

Lin Heng's eyes lit up, and he immediately moved a stone brick that formed the array of the Demon Detective Platform.

Immediately, the text on the spiritual energy interface of the Demon Detective Platform also changed:

[First Demonic Tide: The appearing demonic creatures are demonic worms, low-level demons, belonging to a Level 1 demonic tide.]

[Second Demonic Tide: The appearing demons are demon-patterned warhorses, low to mid-tier demons, belonging to a Level 2 demonic tide. Demon-patterned generals, high-tier demons, have appeared in some areas, belonging to a Level 8 demonic tide.]

[The third demonic tide: The demonic creatures appearing are Rock Armored Demonic Bears, low to mid-tier demonic creatures, belonging to the level 2 demonic tide.]

No wonder he and his entire army of immortal slaves were almost wiped out during the second demonic tide...

It turns out that the appearance of the Demon General directly raised that demon tide to level eight!

Even Lin Heng was secretly alarmed upon seeing this information.

Even with the current strength of his territory, he can probably only handle a level 3 or 4 demonic tide at most.

"Wow! You even made a magic detector?"

Suddenly, an old yet spirited voice came from afar.

The next moment, Lin Heng looked up and saw Tian Qianchen, who had washed his face and beard, running towards him.

"You also know about the Demon Detector?"

"Hehe, our General Administration Division isn't just sitting around doing nothing. Since we've studied array formations, we naturally have records of array formations in the Immortal Realm."

Tian Qianchen proudly stroked his goatee, but the next moment, he put on a humble expression.

He said slyly to Lin Heng, "By the way, could you give me some pointers again today? I stayed up all night yesterday and feel like I've figured something out... I'm practically your student now, you can't just not teach me!"

"You...are you also a student of the teacher?"

Suddenly, a childish voice came from behind.

Tian Qianchen turned around in confusion and looked Song Jingyu up and down suspiciously: "Where did you come from, you little brat?"

"snort."

Song Jingyu said disdainfully, "I am also the master's student!"

"Master? Student?"

Tian Qianchen stared at Lin Heng, somewhat bewildered: "You...you even taught the immortal servants how to construct arrays?"

"She doesn't learn how to construct arrays."

Lin Heng shook his head and said, "Simply put, you are a formation-building type, and she is a spirit herb type."

"What system?"

Tian Qianchen didn't understand.

But suddenly, he seemed to realize something: "Wait, you mean... you can also grow spirit herbs?"

At this moment, Lin Heng narrowed his eyes slightly: "Elder, don't you think you're asking a bit too much?"

"Oh, don't get me wrong, I didn't intend to report it to anyone, I just think you're quite capable!"

Tian Qianchen waved his hand and said, "Besides, I've already acknowledged you as my teacher. If you're taken away and questioned by the other old guys in the General Headquarters, who will teach me how to construct formations?"

Clearly, he was well aware of how dangerous it was to expose his secrets to outsiders.

However, the old man showed utmost sincerity, immediately lifting the back of his clothes and saying, "How about this, kid? If you really don't trust me, give me a Slave Spirit Seal. As long as you teach me how to construct the array, I won't mind calling you master!"

"..."

He's absolutely obsessed with building formations...

However, there's no need to form a slave spirit seal for an old guy like Tian Qianchen.

Lin Heng knew that as long as he remained on his territory, he would never pose a threat to him.

After all, the sheer number of spirit-suppressing tower formations around here is no joke...

"Young Master Lin!"

Suddenly, a celestial servant appeared from the western border.

She said to Lin Heng, "The fox demon from the Western Regions has come to invite you to dinner again."

"Okay, I understand."

Lin Heng nodded.

"Wait, little guy."

Tian Qianchen suddenly grabbed Lin Heng's arm: "The Western Region fox demon your fairy servant mentioned... it wouldn't be a fox demon from the Sand Fox family, would it?"

"Do you also know about the sand fox family of the Western Regions?"

Lin Heng looked at him curiously.

"Of course I know! I even bought a fox spirit from them before!"

Tian Qianchen said smugly, "Let me tell you, the fox spirits over there are absolutely top-notch! If I hadn't been young back then, I almost wouldn't have been able to report to the General Administration the next day... What a pity! That was back then."

As he spoke, he shook his head with some regret.

After all, at his age, even the most alluring fairy maid wouldn't interest him anymore...

"Then you might as well stay here and reminisce about the old days."

Lin Heng shrugged and prepared to leave.

"Wait a minute, little one."

Tian Qianchen suddenly realized he hadn't gotten to the important matter yet: "I almost forgot to ask you, you went to the Sand Fox family... could it be that that old fox invited you?"

Lin Heng paused for a moment, then turned around and asked, "You mean, Baima Meiduo?"

"right!"

Tian Qianchen nodded immediately.

"That's right."

"How many days has he invited you?"

Suddenly, Tian Qianchen's expression became tense.

"How do you know she invited me over several days ago?"

Lin Heng was stunned.

But the more Tian Qianchen said this, the more it seemed that he knew some secrets of the Sand Fox family.

Perhaps it's related to that old fox's ultimate goal.

"Tell me quickly, I'm doing this for your own good, how many days have you been gone?" Tian Qianchen asked Lin Heng anxiously.

After thinking for a moment, Lin Heng said, "Including today, it should be the fifth day."

"broken!"

Upon hearing this, Tian Qianchen stomped her foot.

"What's the explanation?" Lin Heng asked, puzzled.

Tian Qianchen continued, "Did that old fox give you some valuable gifts every time you came back?"

"Yes, every time she comes back, she gives me a lot of spirit stones."

"That's it!"

Tian Qianchen slapped his forehead. "Little guy, you've been targeted by that old fox!"

"Targeted?" Lin Heng asked, puzzled.

Tian Qianchen sighed, "What do you think those spirit stones she gave you were? They were your dowry!"

"According to the tradition of the Sand Fox Clan, when a fox demon takes a liking to someone, she will present a dowry for five consecutive days. If the dowry for these five days is accepted, it means that she agrees to the marriage."

"So that old widow's real goal is to marry you!"
