The sky curtain makes you a useless class monitor, yet you act arbitrarily for eternity?

Yan Cong was startled and instinctively reached out to pinch her cheek.

As a result, the finger went straight through.

It turned out to be just a projection.

"Oh ho!"

Xiao Ai, number 309, immediately took a step back, crossed her arms, and gave him a look of utter contempt for trash.

"You poor wretch, you actually dare to lay a hand on me?!"

Yan Cong's lips twitched.

He was too lazy to waste time with this little brat, so he simply patted the coffee table.

"hurry up."

"Get me the basic forging theory."

"Otherwise, I'll file a complaint against you on the Refining Tower's official website."

"Whoosh whoosh whoosh..."

Xiao Ai, number 309, angrily pointed at the air.

next second.

A projection popped up in front of Yan Cong.

On the projector screen, a middle-aged lecturer holding a pointer stands in front of the blackboard.

He wore a professional smile and nodded at the camera.

"Greetings to all future level nine weapon refiners."

"I am a level eight weapon refiner, Hu Qi."

"Today, I will give you the first theoretical lesson on weapon crafting."

Hu Qi pushed the blackboard, revealing a pre-written lesson plan behind it.

He pointed to the words on the paper with his pointer.

"The complete process of weapon crafting consists of eight steps."

"They are respectively."

1. Raw material preparation and purification.

2. Melt in a furnace.

3. Solidification.

4. Shaping and finishing.

5. Quenching.

6. Tempering and quenching.

7. Engraving and sealing spirit.

"8. The cultivation process concludes."

Hu Qi tapped the first line with his pointer.

"The first step is material preparation and purification."

"Simply put, it's about screening the main metal and ore materials and removing the useless impurities."

The screen behind the blackboard lit up.

Images of ores, spirit metals, and demon bone materials kept switching.

"If it is raw ore, it needs to be crushed and washed to remove stone waste."

"If it is metal, it must be mixed and prepared in a specific ratio."

"Of course, metals and ores can be used together."

"However, all of you future level nine weapon refiners must pay attention to protection."

Hu Qi smiled slightly.

"Mixing the two together can easily cause an explosion in the oven."

Hu Qi continued speaking.

"The second step is to melt it in the furnace."

"It involves putting the purified refining materials into the furnace and igniting the fire."

"The weapon refiner needs to control the temperature of the flame to gradually melt the materials into liquid metal."

"Just a quick note."

"If you want to forge weapons of the third rank or higher, the weapon refiner should ideally have a certain level of martial arts skill."

"Because you need to continuously mobilize your inner energy to control the fire."

"The temperature is too high, causing the metal to vaporize and break down."

"Insufficient temperature prevents the materials from fusing."

"Of course, weapon refiners without martial arts cultivation level don't need to worry too much."

"The refining tower can automatically adjust the temperature according to your settings."

"As long as the source of the fire is chosen well, forging low-level combat weapons shouldn't be a problem."

Yan Cong glanced at the furnace.

I glanced again at the Fire Seed Fee section displayed in the upper right corner.

Is it not a big problem?

My wallet is a huge problem!

"The third step is the solidification of the clay body."

"The solidification of the clay body can proceed in two separate ways."

"Cast billets and forged billets."

Hu Qi clicked on a demonstration video.

In the video, molten metal is poured into a mold and, after cooling, becomes a rough gun head.

"Casting billets, also known as castings."

"Pour the molten metal into a pre-prepared mold and let it cool to form a rough blank."

"This path is suitable for standard-issue spears, armor, arrows, and mass-produced low-tier soldiers."

Everything in the picture.

It turned into a semi-solidified lump of metal and was repeatedly hammered on the forging table.

"Forging, also known as forging."

"It involves placing a semi-solidified metal blank on a cast iron table and repeatedly hammering it."

"Through repeated hammering and forging, internal air bubbles and residual impurities are squeezed out, making the metal texture more dense."

"For fine weapons and personal weapons, this step is almost always necessary."

Hu Qi turned his pointer at this point.

"Step four: shaping and refining."

"This step isn't complicated, but it really tests your patience."

"You must forge the basic shape of the weapon through continuous forging, bending, and trimming."

"The outlines of the sword blade, spearhead, and hilt are all determined at this stage."

"After the rough shape is completed, the rough edges need to be removed with a file and a grinding wheel, and the overall center of gravity needs to be adjusted."

"Here's a reminder."

"Many weapons crafted by newcomers look like knives, but feel like door panels when used."

"The problem lies in the shaping and finishing."

Yan Cong's eye twitched.

These words evoke a vivid image for me.

"Step 5: Quenching."

At this point, Hu Qi's expression became noticeably more serious.

"This step is a crucial turning point."

"Rapidly immerse the high-temperature weapon blank into the quenching medium."

"Spiritual spring water, cold marrow liquid, and demon beast essence blood are all acceptable."

"Rapid temperature differences can alter the internal structure of metals, increasing their hardness and toughness."

"But everyone must remember this."

"Controlling the heat and soaking time depends entirely on experience."

"If the quenching fails, the entire weapon will be scrapped."

Yan Cong's face twitched when he heard the word "scrapped".

If it's scrapped... that's equivalent to losing all the money.

"Step six: tempering and quenching."

"This step of developing low-level weapons can be skipped."

"But if you want to make high-level weapons, it's best not to skimp on them."

"Tempering is the process of reheating at a low temperature and then slowly cooling it."

"The goal is to eliminate the brittleness caused by quenching."

"Otherwise, even if your weapon is tough, it will snap in the blink of an eye once it hits the battlefield."

"Then it's not a weapon."

"That's a show for the enemy."

"Seventh step, inscribe the spirit seal."

"After the weapon has cooled down and stabilized, use a rune engraving knife and spirit ink to engrave arrays and restrictions on the surface of the weapon."

"Common patterns include Gathering Spirit Pattern, Sharpness Pattern, and Strengthening Essence Pattern."

"Only when the engraving is successful can the weapon contain the martial artist's true energy and possess true extraordinary power."

"Of course, this step is also the easiest to ruin all the previous efforts."

"The knife is crooked, the spirit ink is broken, and the rune logic is flawed."

"All of these could lead to a decrease in the rank of a combatant."

"In a more serious case, it could crack open on the spot."

Yan Cong paused for a moment.

He began to feel that every step of the weapon-forging process was like gambling...

Hu Qi finally pointed to the eighth line.

"Step 8: The final step in nurturing the vessel."

"This is also the final step."

"Continuously nurture the weapon with true qi, allowing the spirit patterns and metal to completely fuse together."

"A skilled weapon refiner can also incorporate the soul blood of demonic beasts and rare treasures of heaven and earth."

"This gives the weapon a kind of spirit."

"If we're lucky enough, we might even have a chance to nurture a spirit."

"Of course, for low-level weapons, the seventh and eighth steps can be omitted, so all you weapon refiners need not worry."

Done.

Hu Qi put down his pointer and bowed slightly to the camera.

"Okay then."

"To all future level nine weapon refiners, my instruction concludes here."

"May the art of weapon crafting flourish!"
