The clock had already struck midnight, but the practice building behind the main building of Rhythm House was still brightly lit. The elf Eve stealthily pushed open the door, only to find the empty practice hall with only Rhythm sitting on his knees, eyes closed.

"Since you're here, why won't you come in?" Rhythm, with his eyes still closed, spoke.

Eve stuck out her tongue slightly before slipping through the crack of the door. This was her first time entering the practice building, and it was more like a basketball court than just a building. The ceiling was four stories high, and the space was spacious. There were also some basic weapons placed on the sides.

"Has the teacher not returned yet?" Eve curiously asked, looking at Rhythm sitting on his knees.

"He said he went out to eat with his colleague. He has his own arrangements, so there's no need to worry about him," Rhythm calmly replied. The tightly closed eyes revealed a faint aura, a different kind of pressure, but not intentional.

A year ago, Rhythm discovered that the golden aura on her body started to fade. Since then, she realized that her aura disappeared out of thin air. However, there had been no progress in her strength during this year, but her spiritual awareness had greatly improved, allowing her to perceive within a larger range.

Normally, for warriors, the aura was like the gate of life. However, Rhythm couldn't figure out how her aura disappeared no matter how much she thought about it.

"This is terrible. I still haven't made any progress in the training that the teacher gave me. Whenever I ask him, he always feigns ignorance. I won't be able to complete this week's task again," Eve said, feeling discouraged.

"So you came to find me," Rhythm said, seeing right through her.

"You're so smart, I have to give you that," Eve said, not minding being seen through. She walked up to Rhythm confidently and said, "You must be more powerful than the teacher, right? It's the first time I've felt such a unique pressure from a human. Please, help me!"

"Have you never felt pressure from Lun Hui?" Rhythm curiously asked.

Normally, it wasn't difficult to emit pressure. It was a kind of self-energy fluctuation. Even if you deliberately controlled it, it wouldn't necessarily be completely concealed.

"No..." Eve carefully thought for a moment and then shook her head. "I always feel like he's the same. He's even more lifeless than a stagnant pool of water. Even if you throw a stone, it probably won't cause any ripples."

Rhythm Nolan pondered for a moment, then smiled and said to the little elf, "Eve, right? You don't have to call me '师娘'. I'm only a few years older than you, so you can call me Sister Yun. Can you tell me about the homework and training methods Lun Hui gives you?"

When the little elf heard that Rhythm Nolan was willing to help, her face lit up. She quickly spilled the beans about her master, complaining about Lun Hui's "perverted" behavior. She not only described the training methods and explanations, but also revealed the punishment mechanism for not completing the weekly tasks.

"He's really mean. If you don't finish the task, will he make you wear a cat costume to school for a week?" Rhythm Nolan lightly laughed.

"Yeah, he's really mean. Sister Yun, you have to help me," the little elf said, acting spoiled.

Rhythm Nolan nodded gently and slowly opened her eyes.

Those were a pair of deep starry eyes that seemed to contain infinite vastness, as if they could suck people in. Eve almost couldn't snap out of her trance.

"Wow, Sister Yun, your eyes are so beautiful," the little elf sincerely exclaimed.

But Rhythm only nodded. She was a woman who never lacked words of praise.

"In general, because the purest energy is extremely unstable and elusive, we don't directly use it. Instead, we convert it into fighting spirit or magic. And the mechanism and process of this conversion is ourselves, the humans (or elves) themselves. But this kind of conversion will result in energy loss, and there is no direct source of pure energy," Rhythm Nolan took the dagger from Eve and a faint golden fighting spirit emerged, forming an identical dagger in her other hand!The little elf's eyes widened. What incredible Qi control technique! It could actually shape Qi! However, she quickly thought of something. Didn't she train in one of the ways to shape energy herself?

"So, what is the purest form of energy?" she asked.

"There are many expressions of energy, such as water, electricity, fire, atomic power, Qi, and magic, among others. They are all forms of energy, but true pure energy is completely different from them. It is a completely destructive energy that can destroy all material order," Rhythm Nolan paused for a moment and hesitated. "I don't know much about Lun Hui's technique, but I think he is trying to have you directly use your spiritual power as a source of ability."

No one can directly harness pure energy. It seems to be a law of the world, and of course, the omnipotent supreme god is not included in this.

"Why not just use magic elements or Qi then?" she asked.

"Each type of energy has its own nature. For example, electricity and fire are completely different forms of energy. Perhaps Lun Hui believes that the energy nature of spiritual power is more suitable for a thief's profession, especially for the elastic force explosion. That's why he wants you to master a new energy law instead of directly using the magic power you originally learned."

If magic and Qi cannot be used, then besides the instinctual physical strength, the only power humans can harness is spiritual power. However, it is an extremely unstable power, easily influenced by external factors and difficult to grasp.

"But controlling spiritual power is too difficult. I have no clue where to start," the little elf squeezed the dagger hard, feeling powerless.

Rhythm smiled and placed the Qi dagger she had formed from thin air lightly over the dagger in her left hand. The pale golden Qi quickly submerged into the metal. With a crack, the dagger disintegrated into black powder, but the shape of the Qi remained.

"The original shape of the dagger is due to the force between the particles inside. However, when Qi is introduced as a new type of power into these particles, even the atoms, the new energy disrupts the original order. So, the dagger disintegrates because it cannot maintain its original form. It's difficult to do this, but the method of extracting the power can be improved, such as..." Rhythm Nolan continued speaking as she grabbed Eve's little hand and drew a simple formation on her palm.

"Rhythm, what is this?" Eve asked.

"This is a little trick that can make any form of energy stay easier in your hand. You can use this method to find some clues," Rhythm explained.

Eve quickly tried it a few times and, as expected, the light in her hand was much brighter than before!

She also tried a few more daggers. Now, it only took less than a minute on average to crush one! With less than three days left, the task of a thousand daggers was almost within reach!

"Thank you so much, Rhythm!" the spirited little elf said, running back to continue practicing dagger shaping and being a top student.

Rhythm Nolan didn't know if what she did was right or wrong, but there are no shortcuts in life, and her way was just hoping that the little elf could grasp the method of using spiritual power earlier.

-------------------------------Cut in the Imperative Law-------------------------------

In the old district courtyard in the west of the city, a man suddenly burst through the door.

"Is it done?"

"No, failed. I didn't manage to kill the target at such a close range in the private room. Then we were forced to detonate the scene, but we didn't kill anyone."

"The target suddenly changed hairstyle tonight. All the women had a bohemian style. It's not entirely my fault for not hitting. It's just an excuse," Number Two sat on the sofa and said gloomily.

"That's just an excuse. It's rare for Long Huahe to be away from the target for a few minutes," Number One said coldly. "And Old Three, didn't you say those bombs were filled with toad oil beast fat? Even a master-level warrior should burn up, so how could Long Huahe withstand the flames and walk out with four people?"

Old Three, the man who was looking at the computer in the room, was now searching through the surveillance footage of the KTV corridor that was being monitored all night. He tapped the screen heavily. "Take a look at this..."Number One and Number Two stepped forward. On the monitor screen, a man with four men and one woman behind him forcefully broke through the corridor of a KTV in a burst of black aura.

"Skilled individuals can be found anywhere. What's the meaning of showing me this?"

"Take a closer look at his aura." Number Three switched through several cameras and played different recordings. "After he used the black fighting aura, the surrounding flames were absorbed by him. But the most important thing is..."

With a tap from Number Three's big finger, a fire dragon that exploded on the screen suddenly deviated from its original course at the corner of the corridor and flew towards the black aura out of thin air!

"It actually absorbed the bomb made by the toad oil beast?" Number One exclaimed in shock. "Even the flames were absorbed by him. Why did the building still collapse?"

"His aura is too peculiar. Not only can it absorb flames and the impact waves of explosions, but it can also corrode the structure of buildings. Furthermore, it can attach to objects it touches within a short period of time." Number Three also felt a strange and eerie sensation. "Luckily, you two didn't come face to face with him. I don't think this guy is much weaker than Hasegawa."

"Hmph, I didn't expect there to be another skilled individual besides Hasegawa. Was that old man intentionally deceiving us?"

"I think even the employer is unaware of this situation. Anyway, this mission is too dangerous. We should withdraw." Number Two quickly persuaded.

At this moment, a faint voice emerged from the dark corner of the room...

"You guys are quite clever, considering I followed you for half the city."

The three of them were immediately shocked when they turned around and saw a young man lazily leaning against the wall, nonchalantly watching them intently as they focused on the computer.

"Who are you!? How did you get in...?"

"Don't ask such boring questions." Lun Hui impatiently interrupted. "In this limited life, can you ask some questions with a bit of intellect? Stop asking questions like who are you, how did you get in, what do you want, do you think you're scared little girls?"

Upon hearing this, the three of them felt embarrassed. Number One immediately stepped forward and said, "Since our friend came in without us noticing, he must know a lot about us. What do you want?"

While speaking, Number One secretly made a signal with his right hand to Number Three behind him.

"To be honest, I'm not very interested in who commissioned you to kill. But..."

Before he finished speaking, Number Three suddenly pulled out a handgun from under the computer desk and fired several shots at Lun Hui, while Number One drew a short knife from behind and charged forward!

In an instant, the tongue of the pistol flashed, making the dark room exceptionally bright.

But when Number One's burst of fighting aura missed, he heard a muffled groan from behind him. He quickly turned around with Number Two, only to find that Number Three's head had cleanly rolled to the ground.

"Just speak if you want to. Why do you like to use violence? We're all civilized people, show some manners, okay?" Lun Hui sat on the computer chair, squashing Number Three's severed head with his foot and glaring at it with round eyes.

Too fast! Both Number One and Number Two were taken aback. This man seemed to be like a movie with dropped frames. They couldn't even see the trajectory of his movements, yet Number Three's head had already fallen to the ground!

"Hey, can you assassins at least speak?" Lun Hui continued to step on the lifeless head of Number Three and said, "What do you want to do?"

"As for me? I don't have any specific intentions. I just came to chat with you guys." Lun Hui's words almost made the two of them burst out laughing, but they dared not move at the moment. "I'm not very interested in who you want to kill or who commissioned you. The main reason I came was because I was afraid you would get hold of the recording of my actions. After all, you planted the bomb, which could have hacked into the other party's surveillance system. If you obtained my power data or found out what I look like, it wouldn't be good. So, I reluctantly came all the way here to find you."

Lun Hui paused for a moment, then lightly punched the host of the computer! The black computer instantly fell into pieces!

"But since I'm here, I don't mind listening to your plan. After all, I nearly died in that KTV because of the person who commissioned you. This is the first time I've gone out to play with colleagues, and if you scare me into developing a phobia, I won't dare to go to KTV again. How do you compensate for that mental damage?"Upon hearing this, both individuals understood immediately: "How much money do you want? We'll give it to you!"

However, Lun Hui smiled gently, and with a swift motion, he thrust a dagger directly into the throat of the second man.

"You wanted money, didn't you? Why kill someone?" the leader exclaimed angrily upon witnessing the death of their companion once again.

"Hush..." Lun Hui made a mysterious gesture and said softly, "Don't be so loud. It wouldn't be good to disturb the neighbors, and even disturbing the flowers and plants isn't ethical, don't you agree?"

The leader was furious, but he didn't want to attract the police or even the Knights Squad, considering he had just used a suppressed firearm.

"Aren't you vulgar? Talking about money hurts relationships?" Lun Hui approached and bent down in front of the trembling leader. He pulled out the dagger from the second man's throat and wiped off the blood on the leader's clothes with force.

"You've destroyed the evidence, and you've killed people. Since you don't want money, please spare my life," the leader trembled and said with fear.

This man before his eyes was unpredictable, ruthless, and he could very well end up killing him based on his mood.

"I've said it before, I don't blame you, and I'm not interested in who hired you to kill. But the person who hired you made me suffer tonight, shouldn't I also repay him?"

Upon hearing this, the leader's face immediately turned grim. He forced a bitter smile and said, "So you want to know who hired us, but you must be aware of the assassin's code. If I tell you who the client is, I'll still end up dead."

"You mean you don't plan on telling me, right?" Lun Hui blinked innocently and asked.

"It's not that I don't want to tell you. Either way, if I don't tell you, I'll be killed by you, and if I do tell you, I'll be killed by my colleagues. I can't break the rules," the leader resolutely refused.

"Alright," Lun Hui stood up in one breath and returned the dagger to his pocket. "You have integrity and principles, I like that."

The leader looked at Lun Hui but had no idea what the other person was thinking.

"But my favorite thing is to make people with integrity and principles do things without integrity and principles..."

As he spoke, Lun Hui suddenly struck with both fists, dislocating the leader's two arms, and followed up with a sweeping kick that broke both of his legs!

With such incredible speed and strength, in just half a second, he rendered the leader almost limbless!

"Ah!!!!!!!!!!!" The leader let out a heartbreaking scream. He had originally held onto a glimmer of hope to take action, but he didn't expect Lun Hui to act so fast! There was no time for him to react.

Lun Hui glanced at his phone and confirmed the time.

"Stop screaming, the police will arrive in five minutes. Let's have a nice game of Q&A," Lun Hui dragged over a computer chair and sat on it with a confident stance. "I don't mean to boast, but my interrogation skills are truly legendary..."

Ten minutes later, amidst the sound of police sirens and commotion, Lun Hui slipped away. It was unknown whether he accidentally grabbed someone's clothes, as he had changed his entire outfit.

He also didn't forget to vigorously spray a bottle of fresh mist all over his body before flagging down a taxi and leaving this old residential area in Western Chucheng.
