Lin Yu: The brain's not for sale. Photos cost five.

As the Founder and First Generation "Freud" of the "Psychology Society, "Old Zheng's skill level as a "Player" is indeed quite high.

He was once the only "Player" who had mastered the extraordinary skill of Mental Power, and he also once caused the Demigod who was closest to Deity to fall in the Mist Island Realm through his own schemes.

The "Psychology Society" he founded is now a notorious "illegal organization" on par with the "Marauders".

Every "Player" in the "Death game" who participates in [Instance] in the Ten Realms and engages in activities in reality cannot avoid the code name "Freud".

But...

Even setting aside his identity as a "Player" and the codename "Freud" from the First Generation, Zheng Jianshen is still not an ordinary person.

His theoretical knowledge and academic achievements in psychology, as well as his clinical psychology skills, are already considered top-notch.

Someone like Supervisor Tennyson, with such typical "psychological problems," could be figured out by Old Zheng just from his living environment.

Living environment reflects living habits, and living habits reflect psychological state.

Mental state affects lifestyle habits, and lifestyle habits affect the living environment.

Ultimately, Old Zheng was able to clearly determine...

"His upstairs Gym is just a relatively 'temporary' space for some simple exercises, and the equipment is all basic, only covering the needs of 'normal fitness'," Old Zheng observed the types of equipment and the wear and tear on the walls and floor, and boldly concluded, "His condition suggests that he must have a much more spacious and private 'Gym'."

"There, he can do training programs that are different from 'normal fitness,' but which are 'necessary' for him—presumably the training he will undergo during his 'military service.'"

"And this kind of training allowed him to truly 'relax'—he could confirm that he was still in a 'controllable and safe' state by ascertaining that he hadn't lost the 'special skills' that had saved his life."

Upon hearing Old Zheng's analysis, Nightless Sky Fire Apricot spoke seriously.

"Really? How do you know it's definitely underground?"

Old Zheng immediately replied, "Because he naturally feels safer underground... and honestly, if you want to expand a house and develop extra space, digging out a space underground is the best idea."

Nightless Sky Fire Apricot believed most of Old Zheng's analysis, but still raised doubts. "But... I didn't sense such a space underground—when I went to the underground Alchemy Laboratory, it wasn't just a simple stroll around."

"My Doppelganger Two and I searched the area thoroughly, and my senses didn't detect any unusual Alchemy Energy fluctuations... He shouldn't have installed any hidden alchemical facilities that I'm unaware of."

Old Zheng said in a low voice, "To be honest, I didn't sense it either... but I'm pretty sure this space probably exists; we just haven't found its entrance yet."

As he spoke, Old Zheng looked at Lin Yu.

"Boss, you don't need to look anymore, there really isn't any."

Lin Yu withdrew his Mental Power probe from the ground and looked at Old Zheng: "You sounded so confident, I thought it was your Mental Power that had detected it."

Old Zheng said helplessly, "I really determined this based on my professional knowledge... I don't need to use my Mental Power to detect anything; I can be certain of it."

Lin Yu raised an eyebrow. "Really? What if you're wrong?"

Old Zheng shook his head. "It's hard for me to be wrong about predicting the major habits of people in such typical cases."

"Moreover, I have other evidence to corroborate that my idea is correct."

Old Zheng was speaking, Lin Yu asked a question.

What signs?

"The fact that Lord Nightless Sky Fire Apricot empty-handed so far," Old Zheng said with certainty, "Is that although he may be considered 'clean' among A-Class managers, there are no 'absolutely clean' company executives or upper-level personnel in City That Never Sleeps —everyone has secrets, especially since he has clearly been involved in some conspiracy and may have even lost his life."

"I don't think he was just an innocent victim who happened to be chosen; he must have some kind of secret connection to this matter..."

"Therefore, there must be a space in his residence specifically for handling and storing his 'secret matters'... Such a territorial and insecure ruler would inevitably design and build such a space in his most trusted 'territory,' that is, his 'property,' to facilitate his own actions."

Nightless Sky Fire Apricot clapped her hands. "I believe you, Doppelganger One —let's go, let's go take another look underground."

"To be honest, after you pointed it out, I realized... I did miss some places in his underground Alchemy Laboratory."

"Nightless Sky Fire Apricot said cheerfully, then quickly walked towards the stairs."

Clearly, Old Zheng's words also aroused the Desire of Nightless Sky Fire Apricot to verify the truth of his words.

Lin Yu, Old Zheng, and Stiller followed Nightless Sky Fire Apricot's hurried steps and soon returned to the underground.

Just as Nightless Sky Fire Apricot said, the entire underground area had been transformed into his private Alchemy Laboratory by Supervisor Tennyson —a locked alchemy door had been cracked open by Nightless Sky Fire Apricot, revealing the spacious interior.

The four Alchemy Workbench were filled with various advanced alchemy instruments, and there were also a large number of Alchemical Materials Storage Cabinet and two Large Instrument along the walls.

The cost of this laboratory is obviously exorbitant, reaching the level of independent laboratories of the Three Great Corporations. It's just a bit small in scale, with only one of each type of instrument and not many Alchemical Materials.

Seeing this scene, Lin Yu even vaguely understood why the furnishings upstairs in Supervisor Tennyson's apartment were so simple and plain.

As A-Class manager of the Divine Power Group, he didn't save all the money he earned; instead, he invested it all in setting up this private Alchemy Laboratory.

Nightless Sky Fire Apricot returned to the laboratory with a very clear purpose.

Old Zheng's words did indeed enlighten Nightless Sky Fire Apricot, making her realize what she had overlooked.

After arriving at the Alchemy Laboratory, she went straight to the storage cabinets for Alchemical Materials and the two large alchemical machines placed against the walls.

"Hey!"

Using Metal Grappling Claw, Nightless Sky Fire Apricot dragged them about ten centimeters away from the wall. Then, she took out a Portable Lighting Device, turned it on, and peered through the gap to observe the condition of the wall inside.

Soon, the Nightless Sky Fire Apricot cried out joyfully.

"Ha, there's definitely something fishy going on!"

Nightless Sky Fire Apricot dragged another large Alchemical Equipment to the center of the private laboratory, revealing a smooth wall.

However, if you look closely at the wall, you can see a faint crack in the part that was just blocked by the large Alchemical Equipment.

After feeling around in the crevice for a while, Nightless Sky Fire Apricot quickly confirmed the structure behind it.

Then, she reached out and gently pushed along one side of the gap...

"Karakara--"

With the sound of metal hinges, a Hidden Door opened, revealing a corridor.

Nightless Sky Fire Apricot raised her Arms and cheered.

"Aha, there really is a hidden space— Arthur, your Doppelganger One is amazing! Just by analyzing Supervisor Tennyson, and without even going underground, you were able to pinpoint the hidden space here!"

Then Nightless Sky Fire Apricot approached Lin Yu and said, "So... do you want to sell one of your subordinates to me? I can use 'Pipi' in exchange."

Lin Yu sighed, "That won't do. Old Zheng is a man. Although he may seem like my subordinate or henchman, we're more like 'Partner.' I can't sell him out."

Although from the perspective of the "Death game" certification, Old Zheng was indeed the one who possessed the [Item], and all of his [Summoned Creature]...

However, Lin Yu was still not used to viewing another life with self-awareness and Wisdom, capable of communicating with him, as an object that could be "traded".

Nightless Sky Fire Apricot blinked. "Wow, he's not for sale?"

"Not really, it's just that our world doesn't have this custom, or rather, it used to have it, but it's been abolished now," Lin Yu said seriously. "In short, in our world, any Wisdom life form with independent consciousness cannot be traded... After all, isn't Pipi also an important friend of yours, and can hear you?"

Nightless Sky Fire Apricot nodded. "That's right, but I don't think you'll mistreat Pipi... Besides, saying 'selling' him is really just hoping you'll let him play with me for a few days—I don't really treat him like an object, I genuinely want to be friends with him."

"That's just how we Royal Nobles make friends."

Nightless Sky Fire Apricot said solemnly.

Lin Yu also knew that Nightless Sky Fire Apricot was considered to be a fairly "equal" type among the Noble of City That Never Sleeps.

Therefore, he did not delve into the topic—the differences brought about by these global cultural differences are not something to be overly concerned about.

"However, I'm a little curious, this Hidden Door doesn't even seem special... why didn't you discover it the first time?"

Lin Yu asked.

Nightless Sky Fire Apricot knocked on the open door and said, "Because Supervisor Tennyson is very clever, this door... has no automated devices or alchemical structures involved at all."

"This is a purely Mechanical Transmission Structure, not involving any Alchemy Energy... so when I used Alchemy Energy to search for unusual features, I naturally missed it."

"After all, most of the hidden facilities are achieved using 'ingenious Alchemy Mechanism '."

"Supervisor Tennyson's Hidden Door is indeed a counterintuitive and 'counter-intuitive' design."
