When he saw Lu Yin's five-lined battle force, Mister Mu indifferently said, "It's very ordinary. Although it's not bad, it's not top-notch either. Your spirit is lacking, and your achievements in this path are limited. If you want to be invincible, you must have the courage to swallow the universe and the spirit to surpass the heavens. You can't achieve these things. Battle force isn't that difficult to cultivate, so it can't be considered a fortuitous encounter."
Lu Yin retracted his battle force, and his heart sank. Five-lined battle force was not enough. There were very few Limiteers in the entire universe who could reach that level, especially at Mister Mu's age. Just how abnormal was Mister Mu's disciple selection criteria?
Lu Yin was unwilling to give up, and in the next moment, his domain enveloped the entire area.
Mister Mu frowned. "It's crude and lacks the conviction to be invincible or the determination to win accumulated through countless battles. No matter how you use it, it's just an eye. Everything is under your control, and that's the essence of it. Those who master it can encompass the entire universe and change the heavens. Although you've comprehended it, it can't be considered a fortuitous encounter.
There are too many people in the universe who have comprehended it. "Lu Yin's heart sank again, as this was useless as well. However, Mister Mu's words had reminded him of a special phrase: changing the heavens. The voice that had been left behind on the island at the end of the Ocean of Death had said that the heavens had been changed. The monkey had also said that the powerhouse's autobiographies had recorded that the Rune Technology Technology was a world within a world. Could all of this be related to a domain?
But now was not the time to think about such things. Lu Yin glanced at Mister Mu. This person's standards for selecting a disciple were abnormal beyond imagination. Even a powerful clan like the Daynight clan rarely had geniuses who had comprehended both battle force and a domain at the same time, let alone someone with five-lined battle force.
After some thought, Lu Yin raised a palm and unleashed a Thirty Stacks Fortyfold Shockwave Palm into the void, causing an intense gale to sweep through the area.
This was his strongest attack.
"With your physical strength as the foundation, such an attack can barely be considered a manifestation of your physical body's fortuitous encounter, but it's not that rare. There are strange races in the universe that are born with incomparably strong bodies, and once they reach adulthood, they can easily use 100 Stacks. As a normal person, you're not bad, but you don't meet my requirements," Mister Mu said mercilessly.
Lu Yin's heart sank even further. Mister Mu's strongest attack was useless. Mu really had to use something that couldn't see the light of day?
Mister Mu did not rush Lu Yin. Instead, he quietly looked into the distance as if he did not care about Lu Yin at all.
Lu Yin gritted his teeth. His destiny had been predestined by the heavens. He had been swallowed up by the storm, and it had not been easy for him to climb up the mountain. Then, he saw the person in front of him. Perhaps this person was an unimaginable powerhouse. For the time being, Lu Yin had assumed that this person was on the same level as Northgate Taisui. With such a powerhouse as his master, Lu Yin had to seize this opportunity.
As he thought about it, he decided to use the Sirius Technique. Although the Sirius Technique was not as powerful as Thirty Stacks, it was still a manifestation of fate. Aside from him, there was probably no one else in the Innerverse who could learn the Sirius Technique. According to the Trialmaster, the Sirius Sect was far more powerful than the Daynight clan, so it was impossible for the Sirius Technique to be leaked.
Lu Yin's only worry was that this person would tell the Sirius Sect, which was the worst-case scenario. If that really happened, then Lu Yin would just have to expose Highsage Leon. The Cosmic Sea was independent of the Innerverse and Outerverse, and the monkey had said that even the Neoverse's great powers were afraid of the Cosmic Sea's great battle groups. Lu Yin should be able to protect himself without any problems, so he would just have to take a gamble.
The moment the nine stars revolved around Lu Yin's body, a trace of astonishment flashed through Mister Mu's eyes. "The Sirius Technique comes from the Sirius Sect, and it's one of the core techniques of the Sirius Sect that cannot be taught to outsiders. You actually managed to learn it, which is a pretty good opportunity. Unfortunately, it's only a part of it, and the ninth star clearly does not belong to the true Sirius Technique. This technique can be considered one of your opportunities. If you can learn the entire technique, I will immediately accept you as my disciple. Unfortunately, you will never be able to learn it if you don't join the Sirius Sect."
Lu Yin retracted the Sirius Technique and relaxed. From Mister Mu's tone, he did not seem to have any connections with the Sirius Sect, so he would not betray Lu Yin. After thinking about it, Lu Yin respectfully said, "This disciple does indeed wish to learn the Sirius Technique."
"That's not important to me. Continue," Mister Mu said.
Lu Yin was helpless. Continue?
What else was there?
There were some things that he definitely would not reveal, such as his die innate gift, the Stonewall Scriptures, the Yu Secret Art, and Progenitor Wushang's hide. Wait, Progenitor Wushang's hide?
Lu Yin's eyes flashed. When he had been swallowed into the storm, he had been holding onto Progenitor Wushang's hide, and he had only placed it in his cosmic ring after waking up. Also, he had used Progenitor Wushang's hide to deal with the Cruiser on the beach. Had Mister Mu seen all of this?
A domain allowed one to observe their surroundings, and Lu Yin did not believe that Mister Mu had not comprehended a domain. If he was at the same level as Northgate Taisui, then he would definitely be able to see everything that happened in this space. In that case, there was no need to hide Progenitor Wushang's hide.
Lu Yin raised a hand. "Mister Mu, can this be considered an opportunity?"
In Lu Yin's hand was the piece of Progenitor Wushang's hide that he had obtained from the monkey. It was much smaller than his own, and he would not reveal his own piece. Even if he lost it, it would still belong to the monkey, so he would not feel any heartache.
Mister Mu's eyes flickered, and he nodded. "Progenitor Wushang's item can be considered an opportunity. Remember, try not to reveal it in outer space as much as possible. The astral beasts will be able to sense it."
Lu Yin was disappointed, as he did not see much surprise in Mister Mu's expression. Even Progenitor Wushang's hide had not moved him, and Mister Mu had no intention of accepting him as a disciple. It seemed that Lu Yin's opportunity was not enough.
What else could Lu Yin reveal?
Lu Yin pondered.
Mister Mu looked up. "Let me remind you that you cannot be accepted as my disciple. Everything that happened here will be erased from your memories."
Lu Yin's eyes trembled, and he clenched his fists. He could not accept having his memories erased, as his original memories were incomplete. He could accept being heavily injured or even dying, but he would never accept having his memories erased.
Lu Yin's gaze was resolute, and he decided to use everything that he knew to try his luck.
He raised a fist and punched out, alternating between night and day. This was the Daynight Fist, a fist technique that he had learned from the Daynight clan's inheritance stone on Earth. Although it had become almost useless, it had been a manifestation of his opportunity, as no one else had been able to learn the Daynight clan's battle techniques.
Mister Mu's gaze was indifferent. "There's a powerful clan in the Innerverse called the Daynight clan. This battle technique should have come from them. Alternating night and day can cause damage to one's spiritual force. It's a pretty good attack, and it can be considered an opportunity to learn it. However, it's not enough to move one, and it's far inferior to the Sirius Technique."
"This junior understands. The Daynight Fist is not powerful enough," Lu Yin said.
Mister Mu replied, "It's not that it's not powerful enough, but that you don't know how to use it. Any battle technique will have a huge difference in power when used by different people. When this fist technique is cultivated to a profound level, it can even change the color of space."
Lu Yin was shocked; he had underestimated the Daynight Fist.
"Mister Mu, this junior's opportunity might allow me to become your disciple?" Lu Yin probed.
Mister Mu shook his head. "Not enough."
Lu Yin's brows rose, and he suddenly recalled the scene he had seen in Stargazing Deck. The ancient warship and the claw imprint that had appeared on it. For the Skybeast Claw to appear in that scene, he guessed that it was not as simple as what Undying Yushan had told him. Furthermore, Undying Yushan was a descendant of the Seven Courts' Yu surname, so Lu Yin decided to give the battle technique a try.
Facing the sky, Lu Yin raised his hand and extended it into a claw. The 108 forms of the Skybeast Claw stirred up the void, and a bestial roar rang out. It seemed to come from the distant past, piercing through the void.
Mister Mu's gaze finally flickered once more. "The battle technique of the past has already disappeared in the long river of time. For you to be able to learn it, it can be considered an opportunity. However, it's still not enough to become my disciple."
Lu Yin gritted his teeth. Did he really have to expose the Stonewall Scriptures?
Right, he still had one more thing.
"Mister Mu, this junior's eyes can see things that normal people cannot," Lu Yin said. This place was definitely related to the Rune Technology, which meant that his eyes would be of great use. However, he did not know if Mister Mu had considered the mutation of his eyes. Since he could climb mountains, it proved that he had come into contact with the Rune Technology.
Regardless, he still had to give it a try.
Mister Mu looked into Lu Yin's eyes. "I know that you can see rune lines."
Lu Yin's heart sank, and he smiled bitterly. As expected, Mister Mu knew. Since Mister Mu knew, then perhaps his ability to climb mountains really did have something to do with his eyes.
There was still the Innate Gift Die, the Stonewall Scriptures, and the Yu Secret Art. Which one should he expose?
Lu Yin was conflicted.
"It's rare for you to have such an opportunity at your age. I won't make things difficult for you, and I'll accept you as my in-name disciple for now. We'll talk about it after you've decided whether or not to expose an even greater opportunity. Until then, you can retain your memories," Mister Mu said.
Lu Yin was delighted. "Thank you, Mister Mu. No, thank you, Master."
Mister Mu nodded and waved his hand. A strange mass of quicksand appeared in front of Lu Yin, emitting a hazy light as it floated in the void.
"This is called Fatesand, and it's a gift from Master to you. You can absorb it into your body like a formcast model, and it will awaken different forms for each person. It can make you very strong or very weak, and it's very taxing on your star energy and physical strength. You can choose whether to use it or not," Mister Mu explained.
Lu Yin looked at the mass of quicksand in front of him in surprise. Fatesand?
He had never even heard of it before, so he decided to keep it for now.
He did not know how precious Fatesand was, but it could be considered a supreme treasure, not just in the Innerverse and Outerverse, but also in the Cosmic Sea and Neoverse.
Mister Mu saw Lu Yin casually put away the Fatesand, but he did not seem to mind. "What you just displayed did not include speed."
Lu Yin hurriedly replied, "Disciple's speed battle technique is called Flash Step. I'll use it now."
He then used Flash Step to vanish.
Mister Mu said, "It's not bad. Why don't you combine your aura-concealing technique with your speed to achieve the effect of concealing the void?"
An idea flashed through Lu Yin's mind, and he looked up in pleasant surprise. "Thank you for your advice, Master. Disciple understands." He then activated his Invisible Aura Technique and used Flash Step. His speed did not change, but his aura became even more restrained.
This technique was very simple and practical. Lu Yin had not thought about it before because Flash Step required a foundation of star energy, and the Invisible Aura Technique restrained star energy. The two techniques had opposite effects, but it was not impossible to combine them. As long as one had a certain degree of control over their star energy and knew the distance required for Flash Step and the amount of star energy required, then the rest could be concealed with the Invisible Aura Technique.
It sounded simple, but Lu Yin had never thought of it.
Mister Mu shook his head. "It's too troublesome, but it's enough for you to use for now."
