So I just have to use my whole body, right?

Shen Wu wakes up on a rocky surface, blinking groggily as he gazes at the rough cave ceiling. "Well, that kinda hurt... why does everyone hit my head?" he mutters to himself.

Before Shen Wu can say anything else, Maid Yi's voice cuts through the air. "On your feet, princess," she commands briskly.

Startled by her voice, Shen Wu immediately shoves himself off the ground, executing a flawless backflip and landing on his feet with practiced ease. He then turns to face Maid Yi, who has transformed her appearance, now sporting neatly tied-back hair and lightweight black armor. In her right hand, she holds a long bo staff, which she tosses over to Shen Wu.

Shen Wu catches the staff, feeling its weight in his hand as he examines it curiously. "So, like, what's this staff for?" he inquires, turning his attention back to Maid Yi.

With a plain expression, Maid Yi responds, "For your training... and that's a bo staff, not just a staff."

A smile tugs at Shen Wu's lips as he nods in acknowledgment. "Good to know," he remarks, tightening his grip on the weapon.

Shen Wu, before advancing toward Maid Yi, questions, "But what about you... aren't you gonna use a weapon?" Despite knowing he's weaker, he doesn't want to engage in a fight with an ally without a weapon. Maid Yi's lips twitch into a barely perceptible smile as she responds, "Well, don't worry about me, I... do have a weapon."

Confusion clouds Shen Wu's expression as he observes Maid Yi from a distance. She stretches her hand toward him, but nothing seems to happen. Before he can dismiss her claim as an attempt to intimidate him, Shen Wu's senses sharpen, and he instinctively dodges to the side, narrowly avoiding a strike aimed at his back. Kneeling on one knee, he peers at the object that nearly hit him and then glances over at Maid Yi, who now holds a bo staff crafted from red jade, a black bandage wrapped around a portion of it where Maid Yi grips it.

With a sadistic smile, Maid Yi introduces her weapon "Ah, behold my beloved instrument of agony, the Blood Heaven Staff, a creation born of unbridled malice and insatiable lust for suffering. Originally fashioned from the bones of reinforced iron, it has since been baptized in the crimson torrents of war, a baptism that twisted its very essence into something... deliciously sinister. Picture it, if you dare, as it revels in the echoes of screams, each drop of blood a symphony to its depraved senses. Over twenty thousand souls, their essence now eternally intertwined with its form, a grotesque marriage of flesh and metal. The iron, once stoic and indifferent, now writhes with a perverse ecstasy, its very atoms vibrating with sadistic glee. As I wield it, I can feel its hunger, a ravenous thirst for the exquisite agony of those who dare cross its path. It is not merely a weapon; it is a conduit for my darkest desires, a vessel through which I unleash the depths of my depravity upon the world. Oh, to witness the terror in their eyes as they realize their fate at the hands of this malevolent creation! It is a pleasure beyond measure, a symphony of suffering conducted by my own twisted hand. This, my friend, is not just a weapon; it is an embodiment of cruelty, a monument to the exquisite pleasure found in the depths of human depravity."

Shen Wu meets Maid Yi's gaze and dryly remarks, "Yeah, well, I don't remember asking."

Taken aback by his unexpected response, Maid Yi stammers, "That's not the reaction I was hoping for..." Shen Wu, attempting to maintain his composure, continues, "Look, you ain't gonna scare me... I was beaten, wait no... tortured by Master Gu for a month, so you think a few words are gonna make me shit myself?" Before Maid Yi can respond, Shen Wu interjects, "It's a rhetorical question; you don't need to answer."

Shen Wu points at the Blood Heaven Staff and questions, "Also, I don't see how you having an artifact is fair to me, who has a wooden bo staff. And also, how did you launch it at me?" His voice betrays a hint of fear underlying his curiosity. Maid Yi responds matter-of-factly, "Well, first of all, I don't care whether it's fair or not. And second, I used telekinesis, which only a grandmaster can do."

Shen Wu processes this information, then asks, "So what realm am I in then?" Maid Yi gazes at him from head to toe and declares, "Third rate. And also, you're still naked, by the way. Don't know if you noticed." Shen Wu looks down, realizing his state of undress, and sheepishly admits, "Huh, well, I guess you're right."

Amused by Shen Wu's reaction, Maid Yi glances away, and Shen Wu teases internally, "Ohh, look who's shy." He then asks, "So, do you have any clothes?" Maid Yi, still averting her gaze, responds, "Your clothes are behind you, next to the weapon rack." Grateful for the guidance, Shen Wu retrieves the clothes and notices a black combat uniform that reminds him of Earth's special forces attire. Intrigued by its presence in this world, he quickly dons it, finding it a perfect fit.

After a brief stretch to test its flexibility, Shen Wu remarks, "Oh... it's quite easy to move in." He then picks up his bo staff and strides confidently toward Maid Yi.

Shen Wu stands a few meters away from Maid Yi, who then declares, "From this moment, I'll teach you my martial arts, the Ten Way Blood Asura Arts." Shen Wu nods in approval, commenting, "Now that's a cool name." However, Maid Yi promptly hushes him with a gesture to her lips, rendering Shen Wu unable to speak. Surprised, Shen Wu widens his eyes and silently reflects, "She could do this from the beginning?!"

Maid Yi then asserts, "From now on, you will refer to me as Master and do whatever I tell you to."

Shen Wu nodded and smiled, regaining his ability to speak, but he remained silent for the moment. Maid Yi wasted no time and instructed him, "For your first lesson, I'll teach you the basics of martial arts. Now then, attack me."

With determination, Shen Wu charged at Maid Yi, thrusting his bo staff toward her jaw. However, Maid Yi effortlessly redirected his attack with her Blood Heaven Staff, knocking Shen Wu's staff out of his grip. As he moved to retrieve it, he was met with a swift strike from Maid Yi's staff, sending him tumbling backward.

Undeterred, Shen Wu quickly recovered and caught his bo staff as Maid Yi kicked it toward him. With renewed resolve, he swung his staff at Maid Yi, aiming for her face. But she deflected it effortlessly, simultaneously delivering a precise strike to his foot, causing him to lose his balance and fall.

"Ouch," Shen Wu muttered, quickly getting back on his feet and launching himself at Maid Yi with a flying kick aimed at her chin. However, she easily evaded his attack and struck him in the side with her staff, sending him tumbling once again. Shen Wu managed to stop himself by jamming his bo staff into the ground.

Observing Shen Wu's struggles, Maid Yi advised, "You don't have enough strength to wield a bo staff with one hand, so use both hands." Before she could finish her sentence, Shen Wu rushed at her again, thrusting with both arms. But Maid Yi easily deflected his attack, and Shen Wu felt a sharp pain shoot down his back, prompting him to retreat a few steps, realizing the limitations of his current abilities.

Shen Wu stood a few meters away from Maid Yi, observing her defenses and thinking, "I don't think I can break her defense at all. She hasn't even used any martial arts yet..." Before he could devise a plan, Maid Yi's staff was flung straight at Shen Wu's chest. Shen Wu managed to block with his bo staff, but his staff splintered upon impact, rendering it unusable as a weapon. He tried to stand up, but the pain in his back was excruciating, causing him to grunt in discomfort.

Maid Yi spoke, "Now, if you had let me finish before, you'd know to twist your whole body into that strike, not just your back and arms. Since you're quite strong for a third-rate, doing martial arts wrong could cripple you."

Breathing heavily, Shen Wu listened intently. He realized his mistake and asked, "So I just have to use my whole body, right?"

Maid Yi replied, "Precisely. By doing so, you transfer more energy through your muscles without hurting yourself like you just did."

With newfound determination, Shen Wu ran to the weapon rack and grabbed another bo staff. He launched himself at Maid Yi, firmly planting his feet on the ground. He then twisted his body, transferring energy from his feet to his back, then to his arms, and finally to the end of the bo staff, which he aimed straight at Maid Yi.

She deflected Shen Wu's staff, causing it to strike the rocky ground with force, creating a small hole and multiple cracks. "Don't be too proud, this is just the basics of the basics" despite Maid Yi's reminder not to be too proud, Shen Wu couldn't help but feel ecstatic. He had finally made some progress, even if it was minimal.
