A week has pass.

  The week passed like a whirlwind for Joshua.

  His days were filled with rigorous training under the watchful eyes of his new family members, pushing him to the limits of his endurance.

  Each night, he would retreat to his house from the village made by the chief, after modifying it he now had a secure basement that served as his personal sanctum.

  In here, amidst the glow of the induction furnace and the metallic scent of his new swords and armor, he reflected on his progress and the challenges ahead.

  The basement's thick walls shielded him from the outside world, allowing him to focus solely on his training and experiencing his powers.

  He learned that only he can travel through the crack, any life other than him would be stop before the entrance but he can bring inanimate objects.

  As for the black hole. He didn't dare to go to a new world yet.

  As many days goes by travelling back and fort from Terra and Di.

  During that time he was able to train his Blood Qi, almost filling his every part of his body. Shocking everyone and hailing him as a genius seen only once a millennium because how fast he is improving.

  Deciding to explore other proffession to see what special and how they made items into unique items suited to martial artist the next day.

  Entering the city the next day, he head straight to the old man who swindled him. After gathering info from every smiths he learned that they are either from a clan families or smiths who didn't take apprentice.

  Believing that old man Ye Tie would take him as apprentice if he pays him until he learns the unique heritage. He decided to take the risk and knock on the old man's door.

  The old man answered with a cautious look on his face, "What do you want?"

  "Master Ye Tie," Joshua began with a bow, his voice steady. "I've come to learn the art of blacksmithing from you. I understand that your methods are unique and I am willing to pay whatever price you ask to become your apprentice."

  The old man's eyes narrowed, sizing up the young disciple before him. He could feel the potent energy of the Blood Qi coursing through Joshua's veins, and his curiosity was piqued. "You wish to learn from me, huh?"

  He leaned heavily on his cane, his gaze unwavering. "What makes you think you're ready for what I have to offer?"

  Joshua met his gaze, the determination in his eyes unmistakable.

  "Master Ye, I've come to understand that my journey in the martial world requires more than just Qi. I need to master the art of weaponry to complement my training. I believe your unique techniques will allow me to forge weapons that are one with my Qi, and I am willing to dedicate everything to this pursuit."

  Ye Tie studied him for a moment longer before a sly smile crept onto his face. "Very well," he said, his voice gruff. "But know this: I don't take on just anyone. You'll have to prove yourself worthy of my tutelage."

  Joshua nodded, undeterred by the old man's challenge.

  He had faced and overcome many trials in his short time at the Tri Body Hall, and he was not about to let this opportunity slip away.

  Master Ye Tie led him into a dimly lit room at the back of his shop, where the smell of burning coal and the sound of hammer striking metal filled the air.

  The walls were lined with various weapons and tools, each with a story etched into their surfaces.

  In the center of the room stood an ancient anvil, surrounded by piles of glowing embers.

  The old man gestured to it, his eyes gleaming.

  "Here," he said, handing Joshua a piece of metal, "you will begin by forging your own sword."

  Luckily he had watch hundreds of video on smithing, from old to mordern smithing. Even though he was just starting he had rich knowledge in metallurgy to pave the road of his success.

  He took the metal and placed it on the anvil.

  Joshua took the piece of metal and inspected it closely, his mind racing with the knowledge he had gleaned from countless hours of watching blacksmiths online.

  He knew the importance of temperature and how it affected the metal's malleability. He heated the metal in the forge until it was a cherry red, then quickly hammered it into shape, the ringing of metal on anvil echoing through the room.

  This story originates from a different website. Ensure the author gets the support they deserve by reading it there.

  Master Ye Tie observed him with a keen eye, watching his every move.

  Despite his initial skepticism, he couldn't help but be impressed by the young disciple's understanding of the basic principles. "You've done this before," he said, his voice tinged with surprise.

  "Only in theory," Joshua replied, his breaths deep and measured as he worked the metal. "But I've studied the art of blacksmithing for years."

  He lied as he pounded the metal with a focused intensity, his muscles rippling with the effort. Each strike was precise and calculated, his movements fluid and natural. The heat of the forge seemed to invigorate him rather than weigh him down.

  Master Ye Tie's eyebrows shot up. "Years, you say? And where did you learn this?"

  "I studied it back in my country," Joshua said, pausing to wipe the sweat from his brow. "But I've never had the chance to put it into practice."

  Master Ye Tie grunted, clearly intrigued. "We shall see how much of that knowledge translates to the anvil."

  For hours, Joshua hammered away at the metal, folding and shaping it, alternating between the heat of the forge and the cooling embrace of the water trough. His arms grew sore, and his brow was slick with sweat, but he didn't let fatigue slow him down.

  The metal grew thinner, longer, and took the form of a blade.

  The blade grew sharper with each strike, the steel singing under his hammer.

  The glowing embers reflected in his eyes, which had turned a fierce shade of determination.

  The sword took shape, its curve elegant, its edge sharp enough to split a hair.

  Master Ye Tie watched him work, his initial skepticism giving way to a grudging respect.

  "Your technique is surprisingly good for a novice," he said, his voice gruff with the admission.

  "But true mastery comes from the heart. Can you infuse your Qi into the blade?"

  Joshua paused, wiping the sweat from his brow. He had heard of such a thing before, but his knowledge was limited.

  "I don't know the concept," he said, his voice tight with concentration.

  Master Ye Tie's eyes gleamed, and he leaned heavily on his cane.

  "Ah, so you don't know of it," he said.

  "Good, good." He shuffled over to a dusty shelf and pulled down an ancient scroll, the parchment brittle and yellowed with age.

  "This," he said, unfurling it with care, "holds the knowledges of our predecessors. It is the key to forging weapons that resonate with the Qi of their wielder."

  Joshua's eyes widened as he took in the intricate diagrams and the flowing script that seemed to dance across the page.

  He had never seen anything like it before.

  The scroll spoke of the Qi structure, the veins of energy that ran through the metal, and how to manipulate them with his own blood Qi. It spoke of special ores that, when melded with the steel, could amplify its properties and make it a true extension of its user's will.

  Master Ye Tie's eyes bore into him as he handed over the scroll. "This is a old text, not to be shared with those outside our lineage," he warned.

  "But I can see the potential in you, and the passion that drives you. You will learn this, and you will become a master smith. But you had to also teach me how did you make the sword last time."

  Agreed,Joshua took the scroll with trembling hands, feeling the weight of its history and the trust that had been placed in him.

  He unfurled it carefully, his eyes scanning the ancient symbols and diagrams with a mix of awe and determination.

  The scroll spoke of the Qi structure, a concept that was new to him, and the importance of aligning it with the flow of energy within the metal.

  He nodded slowly, his mind racing with the aplications he could apply of modern tech.

  For the next few days, he split his time between the Tri Body Hall and the blacksmith's shop.

  His mornings were spent with his martial siblings, pushing his body to its limits under the watchful eyes of his masters.

  His afternoons and evenings, however, were dedicated to the anvil. Under the tutelage of Master Ye Tie, he learned to manipulate the Qi within the metal, infusing it with his own energy to create a weapon that was truly his own.

  While sharing modern smithing knowledge to Ye Tie.

  And from time to time he would go back Terra to experiment.

  He learned that he can't train martial arts on Terra but can use it on there.

  I can share knowledge and use it between either worlds but powers are for each own.

  Since he had only been in three worlds, mostly the same sample except for Di.

  He can't come to conclusion yet, so he would leave it for now and go back to training.

  Each visit to the forge was a battle against the unyielding steel, his hammer strikes ringing out in time with the rhythm of his breath.

  The ancient scroll and modern knowledge was his guide, the secrets it contained opening a door to a new understanding of the interplay between metal and Qi.

  The process was grueling, but with every swing of the hammer and every breath he took, he felt himself growing closer to mastering the ancient art.

  Master Ye Tie watched with astonishment as Joshua's blade began to take shape, his Qi seamlessly melding with the metal. It was as if the young disciple had been born to wield the hammer and forge.

  "You learn fast," he murmured, his eyes never leaving the glowing metal. "Faster than any apprentice I've ever had."

  Joshua's cheeks flushed with the praise.

  "Thank you, Master Ye. Your guidance is invaluable." He continued to work the metal, each strike of the hammer a silent declaration of his dedication to mastering this new craft.

  The sword grew longer, its edges sharper with each passing moment, the Qi within it pulsing in time with his heartbeat.

  Lo Kenshi and the others had heard of his new pursuit and would often drop by to see his progress.

  They watched with a mix of amazement and skepticism as the young disciple wielded the hammer with a grace that seemed almost unnatural.

  Yet, as they felt the energy resonating from the blade, they couldn't deny the potency of his Qi.

  They felt joshua was ready to transform Blood Qi to Innate Qi.

  The transformation of Blood Qi to Innate Qi was a complex process, one that required not just physical strength but a deep understanding of the body's inner workings. It was a dance of energy, a symphony of Qi that very few could master.

  But as Joshua focused on the blade, he could feel the power within him shifting, evolving. His mind grew clearer, his intent sharper, and with each strike, he could feel the Blood Qi morphing, growing more refined.

  Lo Kenshi, who had been quietly observing from the sidelines, stepped forward. "You're ready," he said, his voice firm and assured. "It's time to begin the next phase of your training."

  Joshua looked up from the blade, his eyes reflecting the fiery glow of the forge.

  He could feel the anticipation building in his chest, a mix of excitement and trepidation.

  He had come so far in such a short time, but the road ahead was still long and fraught with challenges.
