Immortality: Starting with a grave, I'm invincible when burying corpses.

"Heaven and earth were dark and yellow, the universe was vast and boundless, the sun and moon waxed and waned, and the stars and constellations were arrayed in the sky..."

On a spring morning, the innocent voices of children reading aloud echoed in the courtyard, and the sycamore tree in the center of the yard swayed in the wind, casting swaying shadows on the lawn.

……

The sixtieth year since Mu Ling'er ran away from home.

More than thirty years have passed in the blink of an eye. In the process of searching for the treasure, Mu An has done feng shui consultations, set up a small stall on the street, worked as a musician in a band, and worked as a street craftsman...

The difficulty of the questions increased gradually, but Mu An found them increasingly easier to answer.

Through daily and yearly experiences, Mu An has learned how to communicate with others using these identities.

Or rather, for Yu Mu'an, this was not a difficult task at all; it was simply a matter of changing habits.

Over the course of more than thirty years, Mu An has found more than 180 treasure sites. Including those he found before, the total number is close to 400.

Aside from certain specific requirements, Mu Ling'er did not make things difficult for Mu An. As long as Mu An followed the clues on the treasure map, he would discover treasures that she had carefully prepared.

The world's wonders are hidden in treasure troves. In the Nine Realms, where the concept of scenic spots has not yet emerged, every place Mu Ling'er chooses is a rather niche treasure.

If this were an era of technological prosperity where human footprints are all over the world, these places would surely become scenic spots, bustling with tourists, more lively and less tranquil.

A letter, a scene, a small gift, whether simple or complex—wherever Mu An goes and sees, she accumulates countless handmade gifts.

Walking among these breathtaking natural wonders is itself a form of communication with heaven and earth.

Everywhere Mu An went, he would see stunning scenery that he had never noticed before and meet different people.

Through these encounters, Mu An became more and more easygoing, more and more like his former self.

Of course, this treasure hunt was not without its challenges, and Mu An occasionally encountered some unexpected incidents.

It's like the location of a treasure trove has been occupied by bandits or outlaws, or the original treasure has disappeared with the passage of time.

The former, Mu An, will be left to Liu Yun to resolve, while the latter can only be left with regrets.

In times of war and chaos, the most common occurrence is cannibalism.

Any slightly larger mountain will be inhabited by bandits, and highway robbery is a frequent occurrence.

In this vast world, there are blind people everywhere.

Along the way, the number of bandits and the like that Liu Yun had casually killed had already exceeded 100,000.

Mu An walked and stopped intermittently, finally stopping in Jiuzhou, where the Northern Ridge Empire bordered the Eastern Qi Empire.

In Jiuzhou City, Mu An found the 399th treasure location, but also encountered the most time-consuming problem since embarking on his journey.

Open an academy in Jiuzhou City and cultivate five outstanding students.

……

If it were just about opening an academy or training a few students, it wouldn't be a difficult task for Mu An at present.

This time, however, Mu Ling'er seemed unwilling to let Mu An pass easily, and deliberately added the word "excellent" to the requirements.

Cultivating students and cultivating outstanding students are undoubtedly two completely different concepts.

The former doesn't require much effort; you can just teach it anything. The latter, however, requires careful instruction and a long period before the results are clear.

As a result, the difficulty of passing the test increases dramatically, and the standards become difficult to define.

Whether something is excellent or not has always been a vague concept.

To achieve this goal, Mu An stopped in Jiuzhou City and took over the "Sui'an Academy" left to him by Mu Ling'er.

Besides the already renovated academy, Mu An also received a pleasant surprise.

A white spirit who called him "Grandmaster".

……

It had been a long time since I last saw her. The girl had changed. She was no longer as naive as before, and now she had the air of a great scholar.

When they first met, Mu An almost couldn't remember who she was.

Now, Bai Ling wears round-framed glasses, her long black hair casually draped behind her head. When she sees Mu An, she simply calls him "Grandmaster" before continuing to write furiously.

With the "scratching" sound of the pen tip rubbing against the paper, lines of flowing handwriting appeared.

If Mu An hadn't stepped forward with a blank expression and lifted Bai Ling's head with one hand, Bai Ling probably wouldn't have even bothered to explain herself to Mu An.

"Stop pulling! Stop pulling! I just thought of a great idea for governing the country and was about to write it down! Grandmaster, please don't disturb me!"

"Thump!"

With a crisp sound, Mu An proved one thing with his actions.

Bai Ling has a fine head; when tapped, it produces a very crisp sound that makes one feel relaxed and happy.

"Hiss hiss hiss!!!"

After her head made intimate contact with her fingers, Bai Ling suddenly raised her hands and hugged her head.

"No! We haven't seen each other for decades, can't you be a little gentler, shopkeeper?"

Memories of Bai Ling flooded Mu An's mind. In Mu An's impression, Bai Ling was an unreliable person, and you had to use such a direct approach to talk to her.

This misplaced thought made Mu An completely ignore Bai Ling, and she directly grabbed Bai Ling's head and asked her.

"Explain clearly."

Even when she was lifted up, Bai Ling's expression didn't change much; she just glared with dead fish eyes and complained.

"I want to know too... I'm already so busy, and my master still sent me here, saying that I should learn from you, the shopkeeper, for a while, and also supervise whether you've completed your tasks properly..."

Perhaps thinking of something, Bai Ling's eyes lit up as she hovered in the air, and she added.

"Right, right! Master said that I will be the one to judge whether you pass the test in the end, so I personally suggest that you be nicer to the shopkeeper. Even if you are my grandmaster, you shouldn't hit me on the head like that."

Mu An remained silent, but struck Bai Ling's head with even greater force than before, knocking her so hard that her vision went black and she cried out in pain.

"Ouch! Ouch! Ouch!!! Stop hitting me! I'm sorry, okay... Please be gentle, I'm a celestial being from the literary path, I can't take a beating like those martial arts practitioners..."

"Your master is Mu Ling'er? She sent you here?"

"That's right, that's right! Grandmaster is wise! Master said that whether you teach one or several, it's all the same, so he just threw me over here..."

The master also said that you can't teach students well by yourself. You need to find a reliable person to keep an eye on them, so that the students you teach don't add fuel to the fire of the chaotic situation.

I didn't want to come either. You used to be like a block of ice, and now you're my grandmaster. How can I have a good life here...?

……

After half an hour of rambling, Bai Ling finally explained the whole story to Mu An, and thus stayed at "Sui An Academy," becoming the academy's first student and teacher.

Since neither of them intended to treat the other as an elder, nor did the other intend to treat the other as a grand-disciple, the two naturally reached an agreement.

Bai Ling still addresses Mu An in the same way she always has, calling him "shopkeeper" all the time.

Amidst the commotion, an inconspicuous academy appeared in the eastern district of Jiuzhou City.
