About ten days passed.

On Kunlun's side, it seemed that the matter of him and Xu Yinglian becoming Taoist partners was settled.

The junior sister herself did not express any more objection, but just practiced Kunlun sword-riding technique at the entrance of the cave day and night.

I'm trying my best to defeat my senior brother in swordsmanship!

Of course, being a Taoist partner is ultimately just a relationship of status.

What really matters is that after becoming a Taoist couple, you can legitimately propose dual cultivation...

Let’s not talk about this matter for now, because it involves Xu Yinglian’s obsession and even inner demons, so we have to wait for Master Ziwei to make the follow-up arrangements.

During these few days, Qiu Changtian just calmly circulated his Qi in the meridians, enjoying this hard-earned precious time without being disturbed by his junior sister.

Every once in a while, he would use the Kunlun Mirror's time-space shuttle to return to Mount Shu at the last saved time, and continue to lurk patiently as Ling Yunpo, pretending to practice.

Unfortunately, due to not showing off for many days, the synchronization value of Qiu Changtian's invincible character began to slowly decline.

That morning, Ling Yunpo finally "hardly" passed the three levels and reported the good news to Senior Sister An.

"That's great, Junior Brother!" An Zhisu said happily, "As far as I know, the fastest person in Shushan who passed the three levels took about seven days."

"You were able to enter the Qi Refining Stage within ten days, which proves that your aptitude for cultivation is also first-rate. It's a pity that Master is in seclusion and not here, otherwise he would have known this good news..."

"Senior Sister." Seeing that she was about to cry again, Ling Yunpo quickly changed the subject and asked curiously, "There is someone in Shushan who opened up the Qi Sea in seven days. He is more powerful than me? Who is it?"

"It's me." An Zhisu said embarrassedly, "Actually, it doesn't matter if it's three days faster or three days slower. We Shushan sword immortals don't care about the speed of refining qi. The most important thing is the signature skill of sword control."

"I see." Ling Yunpo pretended to be unwilling, "It seems that my ability to break through three levels in ten days is not considered an outstanding qualification..."

"No!" Seeing his junior brother showing disappointment, An Zhisu quickly changed his words, "The time it takes to break through the three levels can still reflect the quality of one's aptitude!"

"It's just that the difference between seven days and ten days is not that big..."

She stammered and suddenly changed the subject:

"Oh right! Since you have already mastered the sword-controlling technique, Senior Sister will take you to the Sword Pond to get the sword!"

As he said that, An Zhisu called out his own flying sword with a smile, and flew directly into the air with Ling Yunpo on it.

"Senior Sister, what is this flying sword of yours..." Ling Yunpo pretended that he had never seen a flying sword before and asked curiously.

"This is my natal sword, a tenth-rank water sword, named 'Frost'." An Zhisu explained.

Ling Yun groaned and asked again:

"What is the tenth level? What is the water system?"

"I was just about to explain this to my junior brother." An Zhisu smiled.

"Depending on the materials used to make the sword, the environment, the time, and even the refiner and sealing method, the flying sword can be divided into five categories: gold, wood, water, fire, and earth."

"Similarly, according to the different refining materials and the swordsmith's skills, according to the Heavenly Stems Sword Forging Method, the grades from low to high are Gui, Ren, Xin, Geng, Ji, Wu, Ding, Bing, Yi, and Jia. However, we generally use the ten-digit code, that is, grades one to ten."

"Ranks one to nine correspond to the nine realms of foundation building, golden elixir, and Nascent Soul. If the flying sword's rank is higher than that of a sword immortal, it can be solved by sealing. If the rank is lower than that of a sword immortal, it is like a general's weapon is not good enough, which will cause the sword immortal to not be able to exert his full strength."

"And the top-level tenth-order flying sword is a 'flying sword that even immortals can use to its full power', so it is also known as the 'immortal sword'."

"I see." Although Ling Yunpo already knew this, he still asked with a smile, "I wonder if I will be lucky enough to get a magic sword to use?"

"The flying swords in the sword pool are extremely rare, and the tenth-level immortal swords are extremely rare." An Zhisu hesitated for a moment, and then comforted him, "But Junior Brother, don't worry too much."

"The most subtle aspect of my Shushan Sword Controlling Method is 'using the body to nourish the sword'."

"As long as the flying sword itself is not too bad, after you refine it into your natal sword, it can be refined as your cultivation level increases, and there is even a certain chance that its rank will be upgraded."

Ling Yunpo nodded, but thought in his heart:

Instead of getting a ninth-level sword and then using my body to train the sword until it reaches the tenth level, why don't I just get the tenth-level one?

What if he develops to the eleventh level?

Of course, from what Senior Sister implied, it seems that you can't just take any flying sword in the sword pool that you want.

Maybe there are some more tests to pass.

An Zhisu controlled the flying sword and brought Ling Yunpo to the sky above Jianfeng Peak.

The Sword Pond is a pool of emerald green water.

It is said that every drop of water in the lake is actually transformed from a flying sword.

The Sword Immortal of Mount Shu is brave and fierce, and he loves swords like his life, especially in the outside world.

Whenever he competed with other practitioners, he would always snatch the other person's flying sword after winning and throw it into the pool after returning.

Over time, such a sword pool was created.

Countless flying swords were sharpening and fighting each other in it, while from the outside it looked like a pool of spring water rippling around, with ripples forming spontaneously without wind, which was a truly stunning sight.

As for the Shushan disciples who are lacking swords, they only need to stand near the sword pool and practice the Shushan sword-wielding technique to summon out the flying sword that is willing to respond.

As for whether the flying sword is good or bad, you can't force it.

With Lingyunpo's sword light suppressed and stepping onto the ground, An Zhisu explained the history to his junior brother and told him the origin of the sword pool.

Ling Yunpo was amazed and clapped his hands in praise.

As the two walked forward, a Shushan disciple who was guarding the sword pool came over to verify their identities:

"Wait a minute, you are..."

When the female disciple saw An Zhisu's appearance clearly, she immediately cried out:

"You are! The Grass-cutting Sword Immortal..."

Before she finished speaking, the male disciple next to her dragged her behind him, glared at her sternly to silence her, then turned around and said:

"Senior Sister An, are you here to get the sword?"

"If I don't come to the Sword Pond to get swords, what else can I do?" An Zhisu smiled softly, "Could it be that I am here to challenge you to a duel of swords?"

The male disciple was immediately terrified when he heard this and said in a hurry:

"I made a mistake in sword practice the other day and injured my tendons, so I can't fight with swords anymore! Senior Sister An, don't look for me. That name was not created by my peak, but was passed down from other peaks! Every grievance has its perpetrator, Senior Sister An, please don't admit your mistake!"

"Look at what this junior brother said." An Zhisu laughed dumbly, "You are a disciple of the Xisui stage, and I am at the Huafu stage. My cultivation is one realm higher than yours. How can I challenge you to a duel? Isn't that bullying the weak and violating the rules of the sect?"

"Yes, yes, Senior Sister An, do you want to take the sword? Please come this way, please come this way." The male disciple bowed and let her go as if he had been pardoned.

An Zhisu walked forward calmly, Ling Yunpo followed behind her. The male disciple kept wiping his sweat, while the female disciple hid behind him with a look of surprise and fear.

After leaving the two behind, Ling Yunpo took a few steps forward and said with a smile:

"I have seen the fame of Senior Sister."

"How can it be famous?" An Zhisu rolled his eyes at him and said helplessly, "It's just that when Master hastily went into seclusion, the other peaks of Shushan targeted Qingluo Peak. Every now and then, they sent disciples to challenge us and ask for a duel."

"After competing so many times, everyone gets to know each other, so it's not considered a big deal."

"I see, this is what they call 'no fight, no acquaintance'." Ling Yunpo nodded, "But I wonder who the 'Grass-Chopping Sword Immortal' that the senior sister just mentioned is referring to?"

An Zhisu was embarrassed when he heard this, and after a while he said in a muffled voice:

"Who came up with this lousy nickname?"

"After Master went into seclusion, there were too many people who came to ask for swordsmanship lessons, and it was too much of a hassle. In order to establish my authority, I had to be ruthless and use a heavier hand... How did it turn into mowing the grass?"

Ling Yunpo pretended to be enlightened, and sneered:

"I understand. I guess those sword competitors were unwilling to lose, so they spread rumors and slandered Senior Sister."

"Just by hearing the name 'Grass-Chopping Sword Fairy', I thought Senior Sister had killed countless people. This rumor-monger has ruined Senior Sister's reputation. How despicable!"

"How can I kill people without restraint?" An Zhisu gritted his teeth and said in shame, "When have I ever killed people indiscriminately?"

"If the person who comes to fight with swords is polite, I will just stop there."

"If they speak arrogantly or show malicious intent, I will usually just break their natal swords, causing them to suffer damage to their cultivation and learn a lesson."

"Sometimes I couldn't stop myself and pierced someone's chest and stomach... I tried my best to save them afterwards!"

"Senior sister, this is appropriate." Ling Yunpo nodded and said, "Those who came to provoke us maliciously deserved to die! Hmm... So how many people died?"

"Probably... out of twenty times, I only failed once or twice." An Zhisu felt guilty.

Lingyunpo:?
