An Zhisu was very anxious.

The reason why she likes to protect her shortcomings is simply because Su Jian's instructions and teachings have subtly instilled in her some traditional concepts, such as "the master should protect the apprentice", "the father should protect his children", "the senior sister should protect the junior brother", etc.

However, the younger brother’s cultivation strength surpassed that of the older sister. What should I do?

If Su Jian were to make an evaluation, his opinion would be "this senior sister is really not up to standard."

After all, in Su Jian's opinion, I take care of you because I am older and stronger than you, so this is what I should do.

But if I am older than you but weaker than you, who will take care of whom? If I lose the dignity of a senior sister, the relationship will be messed up!

Because of this, An Zhisu has been a little depressed these days and has also drunk a lot of alcohol.

Ling Yunpo saw it all, guessed what was going on, and felt secretly worried.

The work of guarding the Demon Locking Tower is done once every ten days, and each time it takes a whole day, so there is basically nothing to do.

Although he could use his position to play inside the Demon Locking Tower, Ling Yunpo, as a Jindan Zhenren, did not have high demands for external objects like those in the Foundation Establishment Realm and the Huafu Stage. In addition, he looked down on ordinary cultivation resources, so he could only practice swordsmanship with his senior sister to pass the time.

After practicing for a while, I found that my senior sister seemed to have become weaker... Oh, no, it was me who had become too strong.

The power of the first-grade golden elixir's true essence cannot be compared to that of the second-grade golden elixir. Coupled with the bonus of the natural talent of sword bone, its performance in sword-fighting sparring is "infinite power" and "unstoppable".

No matter how exquisite Senior Sister An's swordsmanship is, or how sharp her awareness is, if she can't even block Ling Yunpo's sword, there's no point in fighting.

Ling Yunpo sensed something was wrong. He had originally been holding back on his strength, but when he realized that Senior Sister An seemed unable to hold on, he put in a little more strength again.

As soon as he did so, An Zhisu's innate swordsmanship sensed something was wrong. He guessed that his junior fellow apprentice was deliberately giving in to him, and he suddenly felt more distressed.

Not long after, she asked the sect to let her go out for training.

Jindan Zhenren's application to go out for training is like a worker in a company applying for annual leave. It is his legitimate right, so the sect naturally cannot refuse it easily, so they readily approved it for three months.

When Ling Yunpo learned that Senior Sister An was going out, he immediately took a three-month leave and followed Senior Sister An out of Shushan.

"Where are you going, Senior Sister?" He asked as he caught up with her from behind. "The Demon Cult has just attacked Shushan and failed. There might be an ambush outside. It's too dangerous. How about I go with you, Senior Sister?"

"This, that..." An Zhisu hesitated.

"Could it be that Senior Sister has discovered some clues to the ruins and plans to explore them alone?" Ling Yunpo's expression was stern.

An Zhisu remained silent. Ling Yunpo suddenly shouted in his heart, "How ridiculous!" But he said sadly:

"Since Senior Sister doesn't want to take me there, I guess she has her reasons. Anyway, Junior Brother, I'm going back to Qingluo Peak."

After saying this, he made a move to leave, but An Zhisu grabbed his arm and said quietly:

"Forget it, I won't hide it from you, just follow me."

The two of them rode their swords forward together, and An Zhisu said truthfully:

"The place I'm going to this time is an island in the South China Sea."

"In the classics left by my master, this island was mentioned. It was said that there lived an ancient sword immortal on it who was willing to entertain the Jindan Zhenren from the Shenzhou Continent. That's why I wanted to go there to look for an opportunity."

"I see." Ling Yunpo nodded and did not ask why Senior Sister An had not originally planned to tell him about this - if she did not eat alone, how would she have the chance to surpass her junior brother in cultivation and regain the dignity of being a senior sister?

Humph, I caught you after all.

"Then is it okay for me to go with my senior sister?" he asked pretending to be embarrassed.

"Whether we can find that island is still a matter of debate." An Zhisu sighed, "I heard that the location of the island is not fixed, but will keep changing. Master was fleeing from the enemy's pursuit and ended up there by accident, where he encountered a strange encounter. Later, he returned to look for it, but found that it was gone..."

The two flew at high speed on swords, bypassing the Ten Thousand Mountains in Southern Xinjiang, and finally arrived at the South China Sea.

An Zhisu followed the route left by Su Jian, taking Ling Yunpo to the southeast and southwest, and finally stopped on a vast ocean. He recalled and thought:

"According to what Master said, it's basically around here."

"Why is there no island?" Ling Yunpo scanned the surroundings and asked curiously.

"I guess it still depends on chance." An Zhisu sighed and said, "Why don't we split up and look for it to see if we can come across that island."

"Looking blindly like this is like looking for a needle in a haystack, isn't it?" Ling Yunpo pondered for a moment, then smiled and said, "Senior Sister, do you know how to find an island in this ocean as quickly as possible?"

"What method?" An Zhisu asked blankly.

"Of course, we use birds." Ling Yunpo was confident and said calmly, "Birds flying on the sea need to find islands to rest from time to time, otherwise they will fall into the sea due to exhaustion. Therefore, most seabirds only move between islands and will not fly around randomly."

"As long as we can follow the migration direction of the birds, we can find the nearby islands as quickly as possible. This is always more efficient than a blanket search."

"So that's how it is." An Zhisu suddenly realized and praised him sincerely, "Junior brother, you are really smart! I couldn't have thought of this at all."

"And more." Ling Yunpo continued to add, clapping his hands and laughing, "Since almost no one has heard of this island before, I think even if it appears, it must be in a place where few people go."

"The further south the South China Sea is, the farther away from China, and the less people have explored it. So we can go south from here, follow the seabirds to find nearby islands, and check them one by one."

"Junior brother, you have thought it through very carefully." An Zhisu nodded, gave up thinking and said, "Then I will follow your instructions."

The two of them flew south on their swords, constantly spreading their spiritual sense to scan the distance along the way, looking for any traces of seabirds.

They searched for six or seven islands in a row, all of which were pristine uninhabited islands that had never been visited by humans. An Zhisu was relatively calm, but Ling Yunpo was a little irritated, so he asked Kunlun Mirror in his mind:

"Miss Shi can figure out the location of the Donghua Sect, so you can figure it out, right, Jing? No way, no way?"

"Nonsense." Kunlun Mirror said lazily, "I'm just a mirror, how can I possibly master the art of calculation? If I knew everything, would I still need you to mend the sky for me?"

"Wow, Ah Jing, you are such a loser!" Ling Yunpo said dissatisfiedly, "If you can't even help with such a small matter, what use do I have for you?"

Kunlun Jing suppressed his anger and asked Qingping Jiandao:

"Do you know the island where the ancient swordsman lives?"

"If it's a sword immortal living in seclusion in the South China Sea, I do know one." Qingping Sword said with a smile, "As for whether it's the one your master met back then, I don't know."
