Forging Weapons

"So, you're buying this much steel to forge your own ninja tools?"

At Gu Qi's Ninja Tool Shop, Kakashi Hatake sighed, holding his forehead.

Gu Qi put his hands on his hips, looking smug. "Of course! My ninja tools should be forged by myself!"

"What are you so smug about!" Kakashi complained weakly. "I mean, do you even know how to make ninja tools?"

"I'm so smart, I'll learn it quickly!" Gu Qi said confidently.

"... Sigh, whatever you say!" Kakashi couldn't be bothered to say anything more. As long as Gu Qi liked it, he'd let him do as he pleased.

"Here, these are the experimental equipment I need, along with a bellows, furnace, and some other equipment for forging ninja tools. Get it all done for me quickly." Gu Qi handed Kakashi a list.

Looking at the dazzling array of equipment on the list, Kakashi sighed once more. "I understand. I'll get back to you!"

"Oh, right, the owner of the shop next door's contract is up. But because his daughter married far away, he's not renewing it. So I've decided to knock down the wall and turn the adjacent shop into my laboratory," Gu Qi said.

Kakashi waved his hand weakly. "It's up to you. I don't mind."

Besides, the Hatake Clan had plenty of shops; losing one wouldn't matter.

"Great! Alright, you're not needed here anymore. Go buy the equipment!" Gu Qi forcefully pushed Kakashi out the door and slammed it shut with a bang.

Helplessly scratching his head, Kakashi sighed and left without another word.

Once Gu Qi confirmed from the windowsill that Kakashi had left, he immediately unrolled a scroll and picked up his brush to design his first ninja tool.

Gu Qi needed a ninja tool that could be used for both close and long-range combat. Thus, Gu Qi thought of making a longsword, a longsword that could fire kunai, senbon, or other special projectiles.

According to Gu Qi's design, this longsword would be a normal longsword in its usual state, usable for killing enemies.

However, once the mechanism was activated, the sword's body would split in the middle, becoming a weapon similar to a trident.

When transformed, if the longsword was combined with Gu Qi's Lightning Release Chakra, it would immediately become a special weapon: an electromagnetic railgun launcher.

At that point, Gu Qi would only need to use himself as the battery and the transformed longsword as the launcher's rail.

When using it, he would place the ammunition in the middle of the sword's body, then input Chakra to simulate the railgun's magnetic field and launch the ammunition.

Now that Gu Qi had a concept, the next step was the design.

With the furnace available, Gu Qi could forge even the most complex items, so he could design with confidence.

"To split the sword's body, I'll need to use clasps and gears. Damn it, I studied mechanics before, why can't I remember how to do this?"

Gu Qi irritably scratched his head. He had an idea, but he didn't know how to start.

"Never mind, one step at a time. I'll design the sword's body first." Calming himself, Gu Qi decided to proceed step by step.

According to Gu Qi's requirements, the sword's body needed to be separable.

Furthermore, since the sword's body needed to conduct Chakra, it would definitely need to be mixed with Chakra Metal.

Using ordinary steel ingots would result in a very severe loss of Chakra.

Fortunately, Gu Qi had a Mithril Ingot gifted by the system. He had tried it before and found that Mithril had excellent fluidity and amplification effects on Chakra.

Since the railgun only needed to conduct strong currents along two rails, Gu Qi didn't need to make the entire sword body out of Mithril.

Following his own design, the blueprint for the sword's body was quickly completed.

For the sword's body, Gu Qi designed it in the style of an ancient Longquan sword.

Considering Gu Qi's current height, he designed the sword's body to be 50cm long, with a 7cm wide hilt and a pointed tip.

In the center of the sword's body, the sword's spine, was made of Mithril.

The sword's spine, as the core of the sword's body, inherently strengthened the sword's body. Therefore, ordinary steel could not meet the demands of a transforming sword's spine.

Since Gu Qi's sword's body had to separate, the sword's spine was not a single integral piece.

Only a legendary metal like Mithril could meet Gu Qi's needs.

After the sword's body was designed, it was time for the hilt and guard.

After careful consideration, Gu Qi decided to design the hilt to be 20cm long.

The key to the sword's body transformation was designed by Gu Qi into the hilt and guard.

The hilt was designed by Gu Qi so that the lower part could be rotated.

Inside the hilt, there was a drive shaft. Coupled with small gears inside the guard, rotating the drive shaft would drive the internal gears, causing the sword's body to split and merge.

On the upper part of the hilt, in the center, Gu Qi also designed a button.

The moment the button was pressed, the internal transmission mechanism would push a small Mithril block to a predetermined position.

This way, the Mithril block would connect with the sword's spine, which served as the rail, becoming a complete electromagnetic railgun launcher.

When Gu Qi fired ammunition, he only needed to gather a large amount of Lightning Release Chakra on the hilt beforehand.

This Chakra would then be transmitted along two specific Mithril wires to the sword's spine, which acted as the rail.

When Gu Qi aimed at the target, he only needed to press the button to connect the Mithril block with the two rails, launching the ammunition pre-placed in the middle of the guard.

"Phew, finally finished designing."

After an afternoon of diligent design work, Gu Qi finally completed the design of the railgun sword by dinnertime.

Next, Gu Qi only needed to forge it according to his own design.

After a hasty dinner, Gu Qi entered the laboratory through the lab door with a steel ingot and a mithril ingot.

Walking to the furnace in the corner, Gu Qi carefully read the user manual once more, just in case.

With the user manual firmly in mind, Gu Qi began to decide on forging the ninja tool.

As required, Gu Qi first channeled Chakra into the furnace.

Before long, the once lifeless furnace slowly began to emit intense heat.

When the furnace had basically stabilized, Gu Qi directly threw the steel ingot and mithril ingot into it.

Then, Gu Qi closed his eyes, continuing to channel Chakra while constantly recalling the design of the longsword in his mind.

Soon, an incredible scene unfolded.

The steel ingot and mithril ingot in the furnace seemed to be kneaded by a pair of invisible hands, slowly changing.

First came the blade, first the left half, then the right half.

Next was the hilt, first the small gears inside, then the mithril wires, the mithril blocks, and the transmission mechanism.

For the final hilt part, Gu Qi stopped because his Chakra was depleted.

Looking at the semi-finished sword in the furnace, and the leftover steel ingot and mithril ingot, Gu Qi ate a piece of dried meat. After his Chakra had recovered significantly, he began forging again.

When the intense heat from the furnace disappeared, Gu Qi opened his eyes.

At this moment, a longsword lay quietly before Gu Qi.

This sword was mostly made of steel, with a grayish-white overall color. Only the spine had silver-white lines formed by the mithril used.

Grasping the hilt, Gu Qi weighed it. The sword was about five jin.

With a twist of the hilt, the sword body split in the middle with a clang.

The hilt was 10cm long. After the sword body split, the blades on both sides reached the edges of the hilt.

Therefore, the gap between the sword bodies was two centimeters.

"It seems I need to make some more ammunition," Gu Qi muttered, stroking his chin.

Due to the mithril block in the middle of the hilt, Gu Qi couldn't use magnets to attract ammunition. So, he had only reserved grooves to place the ammunition.

However, this meant that neither kunai nor senbon could be used as projectiles.

Now, only by making ammunition separately could the rail sword's needs be met.

But for Gu Qi, who possessed a super awesome furnace, this was not a problem at all.

Setting the rail sword aside, Gu Qi immediately began to consider the issue of the scabbard.

After all, this sword was sharpened, and Gu Qi couldn't just casually carry it on his back.

What if he accidentally damaged some flowers and plants? That would be a sin.

With time still on his side, Gu Qi took out paper and a pen again to think about the scabbard's design.
