I can see experience bars after being transported to another world.

"Thank you. Um, what should I call you?"

Brent opened his mouth to express his gratitude, but then hesitated and couldn't speak.

"You can call her Ink or Sister."

Lu Yuan interrupted, and at the same time placed the book containing the ink in front of Mina.

"Mina, the ink will always be with you until you master your own talent."

As Lu Yuan spoke, he pointed to the black notebook.

"This is where the ink will live in the future. Remember, no matter where you go, you must take this notebook with you."

Mina held the notebook in her arms with some difficulty, and nodded seriously with her little face.

"Dr. Lu, don't worry, Mina will protect my sister's house."

"Okay, that's good."

He patted Mina's head in approval before looking at Brent.

"Your sister is fine now. I'll take her to the base later for a quick registration and arrange for you to stay in the next room as soon as possible."

"Ah! Dr. Lu, you mean my sister is going to be listed as a member of the Night's Watch?" Brent looked at the ink flying in the air, his mind working quickly, and instantly realized that this was a great opportunity to get on the good side.

"Well, you're in luck." Lu Yuan took Mina's hand and gestured for Mo Shui to follow. "Brent, you can stay at the clinic for now. If anyone comes looking for you, tell them to wait. Also, the room next door is for you and Mina, so remember to tidy it up."

"No problem, Dr. Lu!"

"There's still ink left; you should come in now."

Lu Yuan patted the notebook.

The ink floated over somewhat reluctantly, then tore off a clump of black knowledge from Mina before disappearing into the book.

When Lu Yuan brought Mina to the base, Mary was already waiting.

Mary's eyes lit up when she saw the little girl Lu Yuan was holding, and she quickly stepped forward and patted Mina's head.

"How adorable! Lu Yuan, you have good taste; you seem to be able to bump into all sorts of people."

"I was also a little surprised," Lu Yuan replied, looking at Mina who didn't seem to be resisting.

"Okay, how do I register? Do I need to get the ink?"

"Just come with me. As for the ink, forget it. That little thing doesn't like me."

Mary paused as she touched Mina's hand, seemingly recalling some unpleasant memories.

"Okay, then Mina, you go with Mary... I'll wait for you here."

Lu Yuan spoke softly to Mina.

"Okay, Dr. Lu, wait for me to come back."

Mina wasn't afraid. She nodded her little head, then took Mary's hand, indicating that she could do it.

Mary's smile widened at the sight.

"Alright, Dr. Lu, I'll take the person with me now. It will take some time. I'll bring the person to your clinic once they're ready."

Mary, who was halfway there, suddenly added a sentence.

"Don't worry, there's no danger."

"Um."

Upon hearing this, Lu Yuan left the base with Mo Shui.

Back at the clinic.

Brent was energetically tidying up the room next door.

He was clearly very satisfied with his current home, which makes sense, as the environment here is far superior to that of a low-rent apartment.

Seeing that only Lu Yuan had returned, she subconsciously asked a question.

After Lu Yuan gave a brief explanation, Brent finally felt relieved.

Lu Yuan then thought for a moment, took out a few silver shields from the drawer, placed them on the table, and pushed them in front of Brent.

"Go buy some dinner."

"No, no, no, Dr. Lu, I have money on me!" Brent quickly waved his hand, trying to refuse.

"This is for your future meals, and it also includes your salary."

Lu Yuan's expression was serious, and his tone left no room for argument, "Since you're working here, you have to follow my rules. I don't want my employees working on an empty stomach."

Brent looked into Yuanyuan's eyes, his outstretched hand froze in mid-air, and finally, with slightly reddened eyelids, he put away the silver coin.

"Thank you... thank you Dr. Lu, I'll go right away."

"Okay, remember to let me know if it's not enough."

With Brent gone, the clinic fell silent again.

Lu Yuan sat down and tapped on the black notebook.

"Come out and get to work, don't play dead."

A wisp of black smoke emerged from the notebook in her bosom, ink billowing out: "What do you take this noble book spirit for? You think you can just call it whatever you want?"

"Spit out that book, 'The Basic Structure of the Barrier of Reason.'" Lu Yuan ignored her protest. "I know you've kept it inside."

Ink rolled its eyes and opened its mouth to gag.

"Clatter".

A thick book covered in Xu Jingying's sticky fluid fell onto the table.

Lu Yuan skillfully wiped the cover clean, and just as he was about to open it, a small, cool hand pressed down on the page.

"You're looking at it too slowly."

Ink looked at Lu Yuan with disdain:

"At this reading speed, by the time you learn to build a rational barrier, Mina might already be all grown up?"

"Do you have a faster way?"

Lu Yuan did not refute anything upon hearing this, but instead asked a question.

"Of course." Ink snorted coldly, then fluttered its little wings and flew to sit on Lu Yuan's head.

"Clear your mind, don't resist, consider this your reward for bringing me out."

The next moment, Lu Yuan felt a torrent rush into his mind.

That torrent is not dry text, but pure experience and knowledge that has been deconstructed and refined.

The previously somewhat obscure terminology is now like magnified building blocks, making it clear how to assemble and stack them.

At the same time, a string of grayish-white text appeared before Lu Yuan's eyes:

[Currently receiving knowledge instruction...]

[The barrier of reason is under construction...]

Lu Yuan suddenly opened his eyes, a deep blue glint flashing in the depths of his pupils.

Deep within his mind, a rationality far exceeding that of ordinary people was constantly gathering. Ultimately, under the influence of the ink, Lu Yuan continuously mobilized his own rationality, eventually forming a tough, invisible barrier that completely enveloped his brain.

And at the very moment the barrier was formed.

[Rationality Barrier (Beginner): 3/3. A special technique that condenses one's own rationality into a 'wall,' enhancing the defensive capabilities and resilience of rationality to a certain extent.]

Your understanding of reason has deepened; perhaps you can truly uncover its secrets?

[Rationality III: +2, 2/75.]

As Lu Yuan felt the 'rationality' solidifying deep within his mind, an unprecedented sense of security welled up from within him.

More importantly, Lu Yuan discovered that his sanity limit had actually recovered by two points!

"It really works! The reduction in sanity caused by dream-like abilities isn't entirely irreversible! As long as I master more sanity-solidifying skills, I'll be able to completely get rid of this condition sooner or later!"

Suppressing his joy, Lu Yuan pulled the ink that was still clinging to his head off.

"Ink! Are there any limitations to this knowledge transfer?"

Ink did not answer immediately; instead, it seemed dazed and weak.
