Looking at Michelle's seductive figure, Lu Yin suddenly asked, "I heard you're from the Ten Arbiters Council. Can you tell me who they are?"
Michelle didn't even turn around, only saying, "You don't have the right to know." With that, she disappeared.
Lu Yin's expression remained calm, as this was indeed the case. The identities of these ten were like a threshold that some people would never be able to cross in their entire lives and would never know about, while others would only know about their identities after crossing it. The Ten Arbiters were the Ten Arbiters who had dominated the universe. They were the ten people who stood at the peak of the younger generation.
On the other side, Michelle soared into the sky and felt the raindrops. How had he done it? She was certain that this person couldn't have done it when he first entered the academy. How long had it been since he'd entered the academy? Even a genius would need a few months to reach the realm of infinite change, but this person had done it. Was he a true monster?
Lu Yin stayed in the Rain Observatory for ten days, and he would try once every three days. With his control over star energy, he should have been able to keep his name intact, but he was just a little bit short, and this was all up to his own comprehension.
He'd experienced Da Lei's control of star energy, but he'd only experienced Da Lei's comprehension. He needed his own comprehension, and this step had already taken him ten days.
On the morning of the twelfth day, the sky was still dark green. Lu Yin raised his hand and pushed his name into the rain. He was confident that he would succeed this time.
"Lu Yin" easily crossed the furthest distance he'd ever reached before, charging through the rain until it finally crossed the entire Rain Observatory.
Lu Yin stood up, overjoyed that he'd succeeded. He'd been recognized by the Rain Observatory.
At the same time, a strange feeling surfaced, and his eyes lit up. He could break through to the Melder realm now.
At that moment, the Rainmaster slowly walked over and appeared in front of Lu Yin.
Lu Yin bowed, "Student greets Mentor."
The Rainmaster looked at Lu Yin with admiration, "Your control of star energy has undergone an earth-shattering change in a month. You can be considered a genius."
"Thank you for the praise," Lu Yin replied.
The Rainmaster nodded. "According to Astral-10's rules, those who are recognized by the Rain Observatory can receive personal guidance from a mentor. You can choose a battle technique for me to deduce for you, or you can obtain a battle technique from me. Your choice is yours."
The battle technique reward from Astral-10 was very tempting, but he already had quite a few battle techniques. Whether it was the Sirius Palm, the Skybeast Claw, the Daynight Punch, or even the Flash Step, the Three Stacks were all battle techniques that suited him very well. If he had more, he wouldn't be able to master them.
The battle techniques of Astral-10's instructors were definitely powerful, but Lu Yin did not believe that they could surpass Sirius Art. He already had the ultimate Sirius Art, and he did not need any more battle techniques before he reached the peak of Sirius Art.
He raised his head and earnestly said, "Mentor, I would like to trouble you to help me deduce my own battle techniques."
The Rainmaster nodded. "Alright, go ahead."
Lu Yin took a deep breath and faced the empty curtain of rain. He raised his hand and struck out with his palm, the Three Stacks exploding with three light sounds. This was the Three Stacks.
He analyzed his own battle technique. Sirius Art was too powerful, and he didn't know if the Rainmaster could deduce it. The Daynight Punch was a battle technique of the Daynight Clan, and he couldn't casually reveal it. The Skybeast Claw was already available in Yu Academy, so there was no need to waste it. All that was left was the Three Stacks and the Flash Step. Compared to the Flash Step, the Three Stacks couldn't keep up. He needed more strength.
The Rainmaster looked at Lu Yin's Three Stacks and said, "This is a battle technique that stacks strength. I once met an absolute genius in the Innerverse, and his stacking strength was astonishing. Alright, I'll help you deduce it." He then placed a hand on Lu Yin's arm that had yet to be retracted, pushing his palm in the direction of Lu Yin's palm.
A strange sound rang out, and Lu Yin felt the Rainmaster's strength. One Stacks, Two Stacks, Three Stacks, Four Stacks, Five Stacks, Six Stacks. Lu Yin was shocked to find that the Rainmaster had already reached Six Stacks. The Rainmaster's palm appeared behind Lu Yin's, and the stacks had reached Eight Stacks. "The strength I'll deduce for you should be enough for you to use to the Limiteer realm." The Rainmaster's hand swept through the air, causing nine explosions that shook the curtain of rain and sent out nine shockwaves.
Lu Yin's pupils shrank. Nine Stacks! The Rainmaster had actually reached Nine Stacks!
"The Outerverse also has stacking battle techniques, but there are more or less Nine Stacks. Nine Stacks should be enough for you to use to the Limiteer realm. For now, you should be able to use Six Stacks at most, so don't force it." The Rainmaster then stepped into the curtain of rain and left.
Lu Yin bowed slightly towards the curtain of rain, a trace of doubt in his eyes. Was the Rainmaster really a Hunter?
It was rumored that the mentors of the Astral Combat Academy were all Hunters at the very least.
How could a Hunter be able to deduce Three Stacks to Nine Stacks so easily?
He remembered Tianming mentioning that Nine Stacks had been passed down in Grandtop Weave. If a Hunter could deduce it, then Nine Stacks couldn't just be a battle technique from Grandtop Weave. It could be learned in Frostwave Weave as well, because Undying Yushan was a Hunter.
Or was the Rainmaster not just a Hunter?
This doubt only flashed through Lu Yin's mind, but it was still too early for him to think about it. What he needed to do now was familiarize himself with Nine Stacks.
He had the Sirius Technique and had personally experienced the Rainmaster's Nine Stacks technique, so it wasn't too difficult for him to grasp it. Even so, with his current physical body, he could only use Six Stacks at most. The Rainmaster was right; Nine Stacks was enough for him to reach the Limiteer realm.
A few days later, Lu Yin growled and struck out with his palm. Six explosions rang out as Six Stacks was pushed aside. He had already mastered Six Stacks.
He looked at the traces of blood on his palm. "Six Stacks is still a bit difficult, but it's alright. I can still use it, and my physical body can withstand the Sixfold Shockwave Palm. Six Stacks Shockwave Palms should be quite powerful."
Lu Yin rested for half a day, pondering whether or not he could fuse Stacks with Sirius Palm. He had thought about it when he had mastered Three Stacks, but he hadn't tried it out. This time, he wanted to try it out. If he could really stack Sirius Palm, then his strength would truly skyrocket.
The more he thought about it, the more excited he became. He raised his hand, and stars appeared in his palm as he prepared to strike out with Double Stacks. However, the Rainmaster grabbed his arm and shouted, "Don't you want your hand anymore?"
Lu Yin was puzzled. "Mentor?"
The Rainmaster let go of Lu Yin's arm and asked solemnly, "Are you going to fuse Stacks with that palm?"
Lu Yin's eyes flashed. "Yes."
"You're courting death. You'll only hurt yourself if you rashly fuse Stacks with a battle technique. The stronger a battle technique, the more difficult it is to stack attacks. Otherwise, anyone could multiply their attack, and Stacks would have long since been hailed as a supreme battle technique," the Rainmaster said coldly.
Lu Yin thought about it and agreed; he had been too greedy. If Sirius Palm could stack attacks, then what battle technique in the universe couldn't?
Stacks could be found everywhere.
"Injuring yourself before injuring others. This is the result of fusing a battle skill with superposition. Countless geniuses in the universe have tried, but none of them succeeded. It's impossible to succeed. Every powerful battle skill has its own unique way of operating, and changing it isn't something a junior like you can do. If you had used that palm just now, your arm would have been crippled," the Rainmaster continued.
Lu Yin immediately expressed his gratitude, "Thank you for your guidance, Mentor."
The Rainmaster grunted, but his tone softened, "Some people can use Stacks to increase their battle technique's power at the beginning, but the further you go, the greater the damage. Theoretically speaking, the Shockwave Palm isn't a battle technique, just a technique for exerting force. You can fuse Stacks with it, but don't even think about fusing it with a truly powerful battle technique."
"Yes, Mentor," Lu Yin said gratefully.
The Rainmaster was satisfied with Lu Yin's attitude and looked at his palm, "Your battle technique was very interesting."
Lu Yin was startled, but his expression didn't change, "You've seen it before?"
The Rainmaster glanced at him, "No, but it gave me an unusual feeling. How many stars can you revolve?"
Lu Yin didn't plan on hiding it. Since he'd already been seen, it would only make him seem petty. Besides, he couldn't hide it even if he wanted to; this was Astral-10. "Six stars."
"Six stars? That's too few. This battle technique gives me a feeling of perfection, and six stars isn't enough. Hmm, nine stars might be enough," the Rainmaster said casually.
Lu Yin was puzzled, "Perfection?
I don't understand. "
The Rainmaster waved his hand, "You don't need to understand right now. Perfection refers to the perfect display of a battle technique's power. All the battle techniques you've grasped so far can only be considered beginners. Only that palm strike can reach perfection if you revolve nine stars. Its power is unimaginable."
