From the Abyss Invasion to the Blasting Star.

In the core area of ​​the North City of Lava Crown, twelve obsidian pillars engraved with runes surround a hemispherical furnace.

This is the nuclear-powered demigod forge built by the Dark Iron Dwarves and Xavier Matrix.

"Great mechanical elemental lord, appear!"

After Master Gulu led Lu Heng and the other into the demigod forging room, he opened his arms and began to summon the mechanical elemental lord.

Then, the numerous nanobots, like grains of sand, came together to form a five-meter-tall Gundam.

Lu Heng and Su Muyu looked at each other and smiled, both finding it quite amusing.

To be fair, it doesn't seem wrong to consider the Gundam, composed of nanobots, as a mechanical element lord, if we consider machinery as an element.

Master Gulu exclaimed excitedly, "Mechanical Lord Zero has agreed to forge a demigod weapon with me! That's fantastic!"

When the Aurora Blade was last reforged, this weapon had already been upgraded to SS grade.

Even four years after the Abyss descended, SS-class weapons were still extremely rare.

Demigod-level weapons have never appeared in the human world.

Now, the Dark Iron Dwarf Kingdom has built a demigod forge. If the Aurora Blade can be upgraded again, the boost to combat power will be enormous.

The current problem is whether there are suitable materials to upgrade the Aurora Blade.

Lu Heng voiced the question that had been on his mind.

Master Gulu immediately patted his chest and assured him, "No problem, you've come at just the right time. The demigod forging furnace has just been completed."

"I have discussed it with the Mechanical Lord and the King, and we plan to melt down that Astral Sawtooth into materials."

"Many features of the Astral Sawtooth are similar to those of the Aurora Blade. The materials obtained after melting them can be used to upgrade the Aurora Blade."

The Aurora Blade is Master Gollum's most prized creation.

With Lu Heng's help, this weapon has been upgraded step by step from C-level to S-level, SS-level, and now it is aiming for demigod level.

The upgrade path for the Aurora Blade is equivalent to the process of improving Master Gollum's forging skills.

Now, with the added computing power of Xavier's Matrix, the forging success rate will definitely be even higher.

As the group entered the demigod forging room, Sorelville Bronze Furnace rushed in from outside and apologized:
"The reconstruction of the Lava Crown is basically complete, but there are still many things to do, so I'm sorry for being late."

Master Gollum got straight to the point: "Your Majesty, we are about to start the forge, and you've come at just the right time."

Soreville Copperfurnace hesitated for a moment, then asked, "Such an important event, should we hold a grand ceremony for the entire clan to celebrate together?"

Master Gulu waved his hand, refusing, "Forging a demigod weapon is quite difficult. We don't need such a grand ceremony before we succeed. Let's hold a celebration after we succeed."

In fact, Lu Heng had already noticed that Master Gulu had a very low-key personality when he was at the Quenching Fortress.

As long as there is forging work, he can stay in the Quenching Fortress for a long time without leaving.

Perhaps only those who can endure loneliness and make forging a habit can become forging masters.

Moreover, Master Goru does not like to show his face in public.

Given his status as the master of Quenching Fortress, if he wanted, he only needed to make a trip to Blue Star Capital, and a large group of capitalist families would fawn over him, praising him as an unparalleled god of forging.

But he doesn't need these things, and he doesn't even like this kind of vanity.

He liked to stay in the Quenching Fortress and study forging techniques.

The only thing that could get him out of Quenching Fortress might be helping his people, helping the Black Iron tribe rebuild their kingdom.

Soreville Bronze Furnace, who never went against Master Gollum's wishes, quickly agreed, "Very well, I will have people prepare for the upcoming grand ceremony and await the Master's moment of success."

Master Gulu nodded in satisfaction: "Let's begin. Mechanical Lord, are we ready to cooperate?"

A holographic image of Xavier Matrix appears on the Gundam, which is composed of nanobots.

Xavier's holographic image hovered in front of the control panel. His mechanical fingers swept across the air, bringing up the holographic forging flowchart, and he began explaining the process of this smelting operation:

"According to calculations, we need to melt and break down the [Astral Sawtooth] into seven basic materials."

As he spoke, a holographic diagram illustrating the smelting process appeared.

"The most critical material is astral crystal, which accounts for 12.7% of the total and is also one of the most difficult materials to decompose. This is because this material needs to be melted into a liquid at a high temperature of 12215 degrees Celsius and then rapidly cooled to below zero degrees Celsius to separate it into crystals."

Master Gulu took out his wine flask, took a swig, and became even more energetic: "Can the temperature of the forging furnace be guaranteed to be over ten thousand degrees?"

Xavier Matrix answered affirmatively: "Of course, 12215 degrees, with a temperature error within 0.1 degrees."

Sykes' nuclear energy technology can indeed achieve an error of within 0.1 degrees in precise temperature control.

Master Gulu nodded in satisfaction and said, "Then let's begin. Lu Heng, take out the Aurora Blade. After the Astral Crystal is decomposed, it is very difficult to preserve, so it must be forged immediately."

Lu Heng took out the Aurora Blade and placed this battle-hardened weapon on the forging table.

The blue light flowing along the Aurora Blade's blade reflects the flames of the furnace.

When the Mechanical Lord started the preheating program, a slight tremor appeared on the ground throughout the North City.

The nuclear furnace is ignited to provide heat for the forging furnace.

"Phase one begins!"

The mechanical lord, composed of nanobots, extended its mechanical arm and threw the massive Astral Sawtooth into the furnace.

When the pale blue metal comes into contact with high temperatures, the temperature rises rapidly, and the surface begins to melt slowly.

Master Gollum activated the runes on the forge.

Twelve obsidian pillars simultaneously emitted chains of light, which intertwined to form a six-pointed star pattern above the furnace.

The astral serrations began to melt rapidly, and crystalline droplets resembling mother-of-pearl seeped from their surface.

This smelting process causes a lot of the materials on the Astral Sawtooth to burn and become unusable.

This is normal melting loss and cannot be avoided.

Moreover, the smelting process is precisely calculated so that the materials lost are either of relatively low value or materials that cannot be preserved.

"Material separation rate 78%...85%..." Xavier Matrix's holographic projection announced the progress: "Astral crystallization detected!"

The scene inside the furnace became magical, with metal and transparent crystals like silk being torn apart by an invisible hand, refracting dazzling light and shadow.

Master Guru suddenly took off his shirt, revealing his chest covered with burn scars, preparing to proceed with the next step of the forging process.

After the liquid astral crystals were broken down, Master Gollum used tools to extract the material and placed it in a cooling chamber to cool it.

The cooling chamber uses liquid nitrogen cooling technology provided by Xavier Matrix, which rapidly cools the liquid astral crystal to below zero degrees Celsius, causing it to condense into a single crystal.

Subsequently, the other materials were also decomposed one after another, and seven different materials were finally obtained.

“Phase one is 100% complete.” Xavier Matrix reported the forging progress, then pulled up three 3D models of the redesigned Aurora Blade and asked, “Lu Heng, choose a mold and prepare to begin the forging process.”

The three 3D Aurora Blade models displayed in the holographic image all looked extraordinary.

The three Aurora Blade models weren't designed randomly; their different shapes have subtle differences. Lu Heng was taken aback, thinking that choosing a design should have been discussed beforehand, but instead, the selection was done during the process.

However, all three options were calculated and are all quite good.

After examining the differences between the three models, Lu Heng chose one and said, "This one will do."

Master Gollum picked up the Aurora Blade and threw it into the forge, where it fused with the seven materials forged from the Astral Sawtooth and was forged once more.

The temperature is maintained at a high of 6,000 degrees Celsius, and then gradually cooled down according to the forging process.

Depending on the curing temperature of different materials, the dwell time varies in different temperature ranges.

Half a day later, the melting and casting process was finally completed.

The Aurora Blade was reshaped in the mold, and then Master Gollum used Lava Touch to grab it before it cooled down, placed it on the forging table, and began forging it with the forging hammer.

Bang!Bang!bang...

With each strike, he poured all his power into the sword.

The astral material was woven into the metal under the hammer blows, and the galaxy released by the crystallization seeped along the trajectory of Lu Heng's blood.

When Master Gollum struck the thousandth hammer, all the light suddenly subsided, and a brand new Aurora Blade gradually took shape.

Two hours later, the forging process was finally completed.

Master Guru let out a heavy sigh, sat down to the side, picked up the wine jug, and took a swig.

Several more processes will be carried out by mechanical lords composed of nanobots.

The mechanical lord manipulated three sets of robotic arms to fix the blade, while the laser cutter of the fourth set of robotic arms lit up with a blinding white light.

"High-frequency particle stream is ready."

The moment the laser streaked across the blade, the surface of the Aurora Blade emitted a repelling blue light.

As the two forces collided, the laser began to polish the surface of the Aurora Blade, performing detailed finishing.

The blade is two inches longer than before, with a semi-transparent sky blue surface and a deep blue interior resembling the color of deep space. The edge of the blade features natural patterns formed by the flow of stardust.

Once all the procedures were completed, Master Gulu, who had been dozing off, immediately jumped up, rushed over, and picked up the brand-new Aurora Blade.

He held the brand-new Aurora Blade, frozen in place, completely motionless.

Everyone present looked puzzled, wondering what had happened.

Could the forging have failed?

Many people have this thought in their minds.

The Aurora Blade was forged from a demigod weapon and reforged. If the forging fails, it will be a heavy blow to everyone.

“Master?” Lu Heng reached out and patted his shoulder, then walked in front of him and looked down at his expression.

Master Gulu was already in tears. He looked up at Lu Heng, and then his emotions erupted like a volcano. He raised the Aurora Blade high and shouted, "We succeeded!"

The shout rang out, and everyone present became excited, hugging each other and cheering.

Upon hearing the news, Sorelville Bronze Furnace arrived, his voice urgent as he asked, "Did it succeed? What level?"

"A demigod weapon! Your Majesty, we have forged a demigod weapon!" The Dark Iron dwarf craftsmen who participated in the forging were all so excited that they could hardly contain themselves.

Upon hearing this answer, Soreville Bronze Furnace was equally excited: "Really? We've really forged a demigod weapon?"

He couldn't believe this was true.

Dark Iron dwarves are naturally skilled at forging, but racial talent is one thing, it doesn't mean that Dark Iron dwarves can easily forge divine weapons.

In Thaurisser Bronzeforge's memory, the last time the Dark Iron Dwarf tribe forged a demigod weapon was during the reign of his grandfather, Emperor Thaurisser the Great.

Three centuries have passed, and the forging skills of the Dark Iron Dwarf Kingdom have continued to decline.

There are many reasons for this situation.

The decline in population has led to a decrease in the number of artisans with forging talent, and the probability of cultivating a master forger has also decreased.

Furthermore, tribal decline has increased the pressure to survive.

The entire Black Iron tribe needs to struggle for survival and fight for resources, so naturally they don't have extra resources and materials to forge high-level weapons.

Therefore, the successful forging of this demigod weapon is an exciting event for the Dark Iron Dwarf tribe.

This means that the Black Iron Dwarves' forging technology has returned to the level of the reign of Emperor Sorendal.

Everyone was excited, except for Xavier Matrix, who remained remarkably calm.

He agreed to proceed with the forging process only after calculations showed a high probability of success.

Once Master Gulu calmed down a bit, Lu Heng had the opportunity to take the Aurora Blade and check its attributes.

[Demigod - Aurora Blade]

Item Level: Demigod-level

[Specifications: Length 152 cm, blade width 6.8 cm, weight 62.5 kg]

[Attribute: Attack Power 1650 (Special Effect Bonus)]

[Special Effects: Spirit Slayer LV5, Sharp Blade LV5, Warlord's Will, Astral Slicing]

Divine Skill 1: Dragon Breath Slash

[Divine Skill 2: Dragon's Fury]

[Divine Ability 3: Gravitational Tides]

The moment Lu Heng reached out and grasped the hilt of the sword, his first impression was that it was much heavier. At 62.5 kilograms, weighing over 100 pounds, it was practically unusable for an ordinary person.

Of course, this weight is nothing to Lu Heng's current strength.

Through the subtle perception of his demigod-level mental power, he sensed a powerful force hidden within the blade.

The weapon's attack power increased by nearly three times, but at the demigod level, the weapon's attack power is no longer that important.

What really matters are the special effects and divine skills.

The demigod-level Aurora Blade inherited the original two special effects and received an upgrade.

In addition, two new special effects were obtained: [Will of the Soldier] and [Astral Slicing].

Lu Heng had experienced the [Will of the Weapon Master] effect when he first encountered [Astral Sawtooth]. It is equivalent to the will of the weapon master remaining in the weapon, which can actively damage the enemy.

Even more powerful is the Astral Slice, which means that this sword can directly cleave through the spatial barrier and enter the outer space of the astral plane.

In addition, there is an even more powerful divine skill, [Gravity Tide], a divine skill that fundamentally changes the nature of this weapon. (End of Chapter)
