Leo’s fingertips moved in a specific pattern, and threads of spiritual power connected to the Formation Flags, linking them together.
Ten seconds later, three hundred Formation Flags simultaneously emitted a dazzling light, and the lines of spiritual power between them became invisible.
Thus, the Fire Urging Formation was successfully set up.
Witnessing Leo set up the Fire Urging Formation so quickly, Mike was amazed.
The Fire Urging Formation is divided into four levels: Level One, Level Two, Level Three, and Level Four.
Level One and Two Fire Urging Formations are generally used for crafting magical tools, while crafting spiritual weapons requires at least a Level Three Fire Urging Formation. For top-grade spiritual weapons and Spirit Treasures, a Level Four Fire Urging Formation is necessary.
After completing the Fire Urging Formation, Leo waved his right hand, embedding three High-Quality Spirit Stones into the grooves of the stone ground within the formation.
After setting up the Fire Urging Formation, Leo reached into his Storage Sack and pulled out a crimson sword furnace.
This crimson sword furnace was obtained from the Storage Sack of a Bloodsoul Sect elder whom Leo had slain. It was a top-grade spiritual weapon.
With a thought, Leo made the Crimson Sword Furnace float above the Fire Urging Formation, where it quickly expanded in size.
The enlarged sword furnace was covered in beast patterns, glowing with a crimson light.
“Elder Mike, we are about to begin,” Leo said as he sat cross-legged.
“Yes, Lord,” Mike nodded, picking up a heavy black steel hammer and black iron tongs from the forging table.
Leo formed a hand seal with his right hand, sending a spiritual flame into the sword furnace.
“Fire Urging Formation, activate!” Leo sent another incantation into the Fire Urging Formation.
The crimson patterns of the Fire Urging Formation flickered, releasing intense heat that continuously raised the temperature of the sword furnace.
Leo waved his right hand, and materials such as Cold Spirit Moonlight Stone, Gold Horned Kirin Leopard’s horn, White Obsidian, Purple Gold Stone, and Glacial River Stone entered the sword furnace one after another.
Under Leo’s control, the various materials were quickly enveloped by high-temperature flames.
This step was called smelting.
Five minutes later, White Obsidian was the first to turn red and soften under the high temperature.
“Elder Mike, forge the White Obsidian,” Leo said with a flick of his finger, sending a red-hot piece of White Obsidian flying to Mike’s forging table.
“Yes, Lord!” Mike’s eyes flashed with determination as he used the black iron tongs to grip the red-hot White Obsidian.
Thud… Thud… Thud…!
The forging room echoed with heavy and rhythmic hammering sounds.
On the forging table, Mike held the White Obsidian with one hand using the black iron tongs while swinging the black steel hammer with the other hand.
The solid hammering sound continued steadily, with force increasing evenly. After a hundred strikes, the White Obsidian became a thin sheet.
Mike used a unique forging technique that could remove all impurities from the White Obsidian.
“Lord, forging complete!” Mike waved his right hand, sending the thin sheet of White Obsidian back into the sword furnace.
Under Leo’s control, the thin sheet of purified White Obsidian was quickly enveloped by crimson flames and melted again.
“Purple Gold Stone, go!” Leo flicked his finger again, sending a second piece of red-hot softened ore to the forging table.
The rhythmic hammering sound resumed on the forging table.
Next came Glacial River Stone, Cold Spirit Moonlight Stone, and Dragon Crystal Stone…
In the forging room, time passed by second by second, accompanied only by the continuous sound of heavy forging.
Apart from removing impurities from the Kirin Leopard’s horn under high-temperature flames, all other ores were forged by Mike and then returned to the sword furnace to be liquefied under high heat.
At this moment, eighteen blobs of liquid floated within the sword furnace, enveloped by crimson flames.
Thus, the second step of refining and forging was completed.
Next was the third step: crafting.
With a thought, Leo made the Dragon Sword appear and placed it into the high-temperature sword furnace.
Under the continuous burning of crimson flames in the sword furnace, the Dragon Sword turned red-hot…
An hour later, the Dragon Sword separated into three parts.
The hilt melted into a green liquid, the blade into an icy white liquid, and there was also a blob of faintly glowing essence blood.
This essence blood contained the dragon bloodline within the Dragon Sword.
Leo reached into his Storage Sack again and took out a jade bottle containing a small amount of faintly golden liquid.
This liquid was essence blood obtained from slaying a Gold Horned Kirin Leopard, which also possessed dragon bloodline.
With a flick of his finger, Leo sent the essence blood from the jade bottle into the sword furnace.
The essence blood from the Gold Horned Kirin Leopard quickly merged with the essence blood within the Dragon Sword in the furnace.
The fusion of these two essence bloods deepened the faint golden glow and evaporated some impurities under high heat.
Leo exhaled lightly, his eyes becoming more focused.
Next came the most crucial step-fusing and crafting.
Leo’s consciousness enveloped the entire sword furnace as he formed hand seals to control the fusion of eighteen blobs of liquid within:
The hilt fused with Gold Horned Kirin Leopard’s horn liquid; the blade fused with Cold Spirit Moonlight Stone liquid… essence blood infused into the blade…
After completing the fusion came the penultimate step: crafting an artifact embryo!
As a Cultivator, there was no need for mortal blacksmith molds; only spiritual control was required.
Under Leo’s spiritual control, a sword-shaped artifact embryo slowly took form within the sword furnace.
This process required immense mental effort and patience.
Another hour later, the sword-shaped artifact embryo was fully formed within the sword furnace.
“Elder Mike, step back!” Leo commanded in a low voice.
Mike quickly moved away from the forging table.
Whoosh!
A completely crimson sword embryo flew out from the sword furnace and landed on the forging table.
“Hand me the hammer and tongs!” Leo appeared in front of the forging table in a flash and spoke to Mike.
Mike handed over the black steel hammer and black iron tongs to Leo.
Leo gripped the hilt with black iron tongs while channeling spiritual power through his body and swung the black steel hammer onto the blade.
Thud… Thud… Thud…!
Clear and powerful hammering sounds echoed through the forging room rhythmically and steadily.
Each strike of the black steel hammer carried immense force. On the forging table, the sword embryo became thinner and sharper with each blow.
“This is… the Thousand Hammers Refining Technique!” Watching Leo’s forging movements, Mike was once again astonished.
The Thousand Hammers Refining Technique is an advanced forging method that requires immense physical strength and deep spiritual power.
After completing this round of forging, sweat began to drip from Leo’s forehead.
Then Leo controlled the sword embryo back into the sword furnace for further smelting.
Half an hour later, Leo retrieved the sword embryo again and continued hammering it using the Thousand Hammers Refining Technique.
This process repeated nine times until finally, a perfectly shaped sword embryo emerged.
