As we descended from the mountain, we stopped at Grandpa Kaewon's workshop. He handed Luna a ring, and my intuition told me it was no ordinary Level 3 ring. This was a Rank 6 mana enhancement ring, likely worth around 400 gold coins.

I asked him, "Grandpa, I think the ring you've given is more than Rank 3 in its build. It looks stronger in its aura."

Grandpa Kaewon chuckled and said, "Oh, you realized it? Yes, it's a Rank 6 ring. But you don't need to pay for it. Consider it a gift for your celestial emergence and becoming my first disciple."

Then he said, "Luna, wear the ring."

"Yes, Grandpa," she replied.

"You will be able to sense the details about other objects. It won't be as good as seeing the writing on paper, but you'll be able to make out the dots on a blind person's book without touching it."

A Level 3 ring for Luna, who was currently Level 1, would have boosted her to somewhere between Level 2 and 3. But a Rank 6 ring would elevate her to Level 4, like seeing everything in blue and suddenly gaining infrared vision. I turned to Luna, who was carefully running her fingers over the intricate patterns on the ring.

I said, "Thank Grandpa for the gift, Luna."

She smiled brightly, her face sparkling with excitement. "Thank you, Grandpa, for this wonderful gift. It's really useful."

Grandpa Kaewon smiled warmly and replied, "Why don't you wait here and let your sister return to the mansion? I was just about to make some Scorpion assassin knives."

"Goodbye, Seraphina," I said, waving my hand. "Take care on your way back."

She smiled and nodded. "You too, Dajit. I'll see you soon."

As the horse carriage moved out of sight, I turned and made my way back to Grandpa Kaewon's workshop.

The Scorpion knife was a masterpiece. It had a unique double-edged blade, its curves resembling the deadly tail of its namesake. The main blade was sleek and razor-sharp, tapering to a vicious point that promised swift, precise strikes.

What set the Scorpion knife apart was the secondary blade extending from the base. This smaller blade curved gracefully over the wielder's finger, fitting snugly between the middle and base knuckles. 

Within our assassin group, we called it 'Venom's Kiss' because it typically had a hole to store poison, coating the secondary blade without affecting the primary blade's strength.

As I nodded, agreeing to learn, Grandpa Kaewon continued, "A good Scorpion knife is generally made from Level 2 or 3 Abyssian snake monsters, whose teeth are hollow inside, allowing the user to store poison just like the snake does."

He began by selecting a piece of metal from a pile on his workbench. "This," he said, holding it up for us to see, "is a piece of Abyssian snake tooth. It's incredibly durable and perfect for making a Scorpion knife. I have a Rank 2 quality of material, and there are a total of 5 ranks in quality."

We watched as he heated the metal in the forge until it glowed a bright orange. He then placed it on the anvil and began to hammer it into shape.

Each strike was precise, and the hammer itself started glowing as Grandpa's power of Ignis Phoenix Level 7 was in full effect. With every strike, the fire seemed to grow hotter, reacting to Grandpa's star.

As he worked, he explained the process to us. "The key to a good Scorpion knife," he said between strikes, "is balance. The main blade must be sharp and strong, capable of piercing armor. But the secondary blade needs to be hollow to hold the poison. It's a delicate balance, and it takes years of practice to get it right."

As the blade took shape, Grandpa Kaewon moved on to create the hollow channel for the poison. Using a thin, sharp tool, he carefully carved out the inside of the secondary blade. His hands were steady and sure, despite the painstaking work.

"This part is crucial," he explained. "If the channel is too wide, the blade will be weak and could break in battle. Too narrow, and it won't hold enough poison. You have to find the perfect balance."

When the channel was complete, he heated the blade one final time to harden it. Then he quenched it in a barrel of oil, the metal hissing and spitting as it cooled. The final step was to sharpen the blades, a process that required both strength and finesse. Grandpa Kaewon used a whetstone, carefully honing each edge until it gleamed.

Finally, he held up the finished knife for us to see. It was a work of art, with the main blade gleaming in the light and the secondary blade curving gracefully over the handle. "Here it is," he said, handing the knife to me. "The Scorpion knife."

I took the knife, feeling its weight in my hand. It was perfectly balanced, and the grip was comfortable and secure. It felt like a Rank 4 blade. I could see why Grandpa Kaewon was so proud of his work. I knew how to use a Scorpion weapon but never knew that each strike from the hammer could change its angle of penetration.

Then Grandpa Kaewon took the knife back and said, "You will need to work hard to achieve this level of skillfulness. I think within a few years, you should be able to make one for yourself."

He handed me a rusty small knife and asked me to hammer it as he did with the Scorpion knife to bring it back to life. Grandpa said, "I don't want you to be the best from the start. I just want to see how much you can learn from watching the first time."

"Yes, Grandpa," I replied.
