130: My heart skipped a beat.

If you want to learn the most essential medical arts, perhaps the only way is to apprentice under an Advanced Doctor, deepening your medical knowledge and enriching your medical experience!

Of course, all knowledge must eventually be put into practice. For that knowledge to truly become your own, practice is crucial.

There are mainly two types of practice. The most effective one, naturally, is to go out and treat others, thereby increasing your own experience!

As for the second type, although also useful, it carries a degree of danger.

That is to find illness in yourself, and then treat yourself!

Or, to find illness in others and treat it—though that is somewhat unethical!

Enough small talk. Today happened to be the first lesson in the rotating lectures on basic medical knowledge at the Imperial Medical Hall.

At this moment, the Instructor was lecturing at the front of the hall, but only a handful of people were listening.

Nangong Yu watched, feeling that the old Instructor seemed somewhat listless and uninterested.

Nangong Yu and the others did not stop. He walked straight to the door, knocked, and bowed slightly, saying, “Student Nangong Yu apologizes for disturbing Instructor Duan.”

The old Instructor, suddenly interrupted, frowned slightly, but upon seeing that it was Nangong Yu, his tight brows relaxed.

He forced a smile, “Little Prince, have you come for something? If you have questions, you can go to the lecture hall next door; there are two Instructors there!”

Nangong Yu smiled gently, “I apologize for disturbing Instructor Duan. I simply came to sit in. Whatever I can absorb, I will!”

Hearing this, Instructor Duan was slightly startled. Thinking of the previous rumors, he immediately smiled and said, “Then please, Little Prince, come in and take a seat!”

“Thank you!”

Nangong Yu nodded, led the two people inside, and sat down by the window!

“Qing Ling, sit down!”

Seeing Qing Ling standing beside him, Nangong Yu pointed to the empty seat on his left.

“No need, Young Master, I...”

Qing Ling hurriedly waved her hand, but Nangong Yu casually said, “If I tell you to sit, then sit. Why so many formalities?”

“Yes, thank you, Young Master!”

Qing Ling nodded and obediently sat down.

Seeing that they were seated, Instructor Duan pondered for a moment, “Since the Little Prince has just arrived, I will briefly review the content covered this morning before continuing with the rest of the material.”

Saying this, Instructor Duan began lecturing from the beginning. The few students below frowned slightly upon seeing this, but said nothing.

As Nangong Yu listened, he grew weary and leaned against Qing Ling's arm, slowly drifting off to sleep.

Seeing this, Instructor Duan frowned slightly but said nothing, continuing his explanation.

However, this time, his explanation was completely rushed, truly just a quick review.

In just a moment, the lecture returned to the point it was at when Nangong Yu first entered.

But after he resumed his regular lecturing speed, he neither stopped nor woke Nangong Yu.

He understood now: this Little Prince had no interest in studying medicine and was just here to pass the time.

Time flew by quickly.

Instructor Duan finished the lecture, tidied up, and left the hall.

Seeing this, the students glanced over and quickly left the lecture hall as well.

Seeing this scene, Qing Ling looked down at Nangong Yu sleeping in her arms, unsure whether she should wake him.

She looked at Su Xingmeng, who shook her head slightly, “Let the Young Master sleep. Just carry him back!”

Hearing this, Qing Ling quickly nodded.

And Nangong Yu, who had originally intended to 'wake up,' simply decided not to open his eyes.

The two cooperated, allowing Nangong Yu to lean on Qing Ling's shoulder, and carried him out of the lecture hall.

It was currently around the Fourth Quarter of You Hour, and the students were heading towards the exit of the Supervision Office.

Seeing the trio's combination, they raised their eyebrows slightly but said nothing, stepping aside slightly.

Soon, the three people walked out of the Supervision Office.

When Shangguan Yuexi saw Nangong Yu's state, she couldn't help but smile slightly, “No need to ask, the Little Fellow must have fallen asleep during the lecture, right?”

Su Xingmeng and the other person nodded slightly. Shangguan Yuexi didn't say much, gently taking Nangong Yu into her arms, “Let's return to the Prince's Estate!”

Just as the group was about to turn and leave, they saw Nangong Ruoxue rushing over anxiously.

“Greetings, Second Imperial Aunt!”

After Nangong Ruoxue finished her salute, she looked at the 'sleeping' Nangong Yu, a hint of confusion flashing in her eyes, “Yuer, is he asleep?”

Shangguan Yuexi nodded slightly, “Let's go. Want to walk a bit together?”

Nangong Ruoxue nodded... Peaceful time always passed quickly. Nangong Yu had leisurely spent four years in the Supervision Office.

To be precise, he spent two years each in the Imperial Medical Hall and the Profound Poison Hall, totaling four years.

Of course, those four years might have to be halved.

Seeming to understand Nangong Yu's aversion to conflict, Shangguan Yuexi didn't demand anything of him, ignoring all his actions, as long as he was happy!

Therefore, for half the time, Nangong Yu didn't go to the Supervision Office. Instead, he took Qing Ling and Su Xingmeng to play in the Market District or outside the city!

Of course, no matter where they went, Aunt Shen was secretly protecting them.

Early morning.

After Nangong Yu woke up, he saw his mother looking at him with a complicated expression, causing a sudden clench in his heart.

He had noticed his mother's mood seemed off recently, so he specifically asked Ying You about it.

And he learned the reason.

The Three Thousand Zhenbei Army, Imperial Grandmother, Maternal Grandmother, and his mother, among others, had been stuck at the Mid-stage Spirit Venerable Realm for some time.

Recently, Imperial Grandmother and the others seemed planning a collective Breakthrough, after which they would leave the Mortal Realm.

And those close to Shangguan Yuexi, such as Ji Ziyu and the others, had also heard the Mysterious Person's explanation via Shangguan Yuexi.

Furthermore, Ji Ziyu, Xuanyuan Lingyun, Nangong Aotian, Han Liyan, Nangong Ruoxue, Nangong Ruoshui, and Nangong Jingqi—these seven people—also received a Heaven-Defying Fate Change, and their Spiritual Roots collectively Advanced to Heavenly Spiritual Roots!

Three slots for the Heaven-Defying Fate Change remained!

The price was that Nangong Yu had withdrawn 5 billion Spirit Stones from his mother's Spirit Jade Card, leaving the card nearly empty.

In addition, Ji Ziyu, Nangong Aotian, and Xuanyuan Lingyun respectively sent 2 billion, 1 billion, and 5 billion Spirit Stones, saying they were for Nangong Yu's pocket money.

Of course, this wasn't important.

What was important was that they knew the situation of the Three Thousand Zhenbei Army and Nangong Yu's situation.

Therefore, Imperial Grandmother and Maternal Grandmother advised his mother to take the Three Thousand Zhenbei Army to the Holy Domain, and once they were stable, then have Nangong Yu go there.

Clearly, his mother was tempted and had been struggling with this decision recently.

Nangong Yu looked at his mother's complicated expression, sighed, and said, “Mother, if you have something to tell Yuer, just say it. Seeing Mother so distressed makes Yuer feel bad too.”

Hearing this, Shangguan Yuexi's expression changed slightly, and she couldn't help but hug Nangong Yu tightly.

Two lines of clear tears streamed down her beautiful cheeks and rolled onto Nangong Yu's pajamas.

Nangong Yu didn't speak, he just hugged his mother tightly, waiting for her decision.

After a long time.

Shangguan Yuexi took a deep breath, parted her crimson lips, and said, “Yuer, Mother may have to be separated from you for a while.”
