Fire Elemental Plane, Molten Altar.

The void suddenly opened a huge portal with a dark red glow.

It can be seen that this void portal is not stable, and the spatial fluctuations above the light gate composed of fire elements are so clear and obvious that the constantly vibrating dimensional space can be perceived from a hundred miles away.

It took a long time for the Void Portal to settle down, and Grim dragged the dragon lich captive across the Light Gate back to the Molten Altar.

"Welcome back, master!" Sensing spatial fluctuations, the Ember Web Spider Mother Rakbeth and the Split-Brain Sock, who were in charge of the specific affairs here, hurried to the light gate and greeted Grim.

"Hold this bastard down and don't let it run away......" Grim tossed the dragon lich in his hand to the spider mother, then stood firm and began to carefully examine the molten altar in front of him.

At this moment, the Molten Altar has become a huge construction site.

Thousands of engineering magic machines are busy near the lava lake, carrying various materials such as stone, magic materials, magic alloys, and more. More of the native creatures of the fire plane were driven to level the land as coolies, using volcanic rock to build a temporary path to the center of the lava lake.

On the shores of the lava lake, a huge metal furnace was erected, and the thick black smoke from the straight upward exhaust vent almost obscured the entire valley of the molten altar.

The demonic iron ore from the extraterritorial camp was put into it, and then concocted in a series of processes such as crushing, stirring, screening, quenching, and purification, it was turned into a demonic iron alloy that could be used in the construction of the witch tower.

Metal pillars three meters thick and twenty meters long have been concocted, and they are stacked densely on the edge of the lake, waiting to be put into the lake as the base of the witch tower after drawing the magic patterns and rune witch array.

Since the location of this witch tower cannot be leaked out at will, these delicate tasks can only be done by higher-level, more intelligent witchcraft golems. Therefore, the progress of the project is not too fast.

At the current rate of progress, it will take more than twenty years for this tower to be fully completed. This speed is almost turtle speed compared to the Silver Alliance, but for the sake of safety, it can only be so.

After all, there are a large number of arcane wizards in the Silver Alliance, and the stones, magic materials, and rune witches they use are all half-finished products that have been prepared in advance. All they had to do was put it all together at the tower and merge it into a whole.

And Grim wants to build a witch tower, and every stone, every portal, the magic pattern and the witch circle on it need to be carved a little bit. With the scale he envisioned the Witch Tower, it was a lot of work that could drive people crazy.

To be honest, if it weren't for the fact that Sock could multi-purpose and manipulate more than a dozen witchcraft puppets to draw the witch array at the same time, I'm afraid the tower would have taken much longer.

Grim slowly glanced around the entire construction site, and basically grasped the general situation here, and saw that everything was going according to plan, and he finally nodded with satisfaction.

"How about it, the project is going well, right? If you have any problems, just tell them together, and while I'm here, I'll solve them for you!"

Hearing Grim's inquiry, Sock couldn't help but smile bitterly: "Master, the temperature of the lava lake here is too high, and ordinary engineering magic weapons will melt when they go down." Even if the specially concocted fire-resistant magic weapon goes down, it won't last long. Therefore, there is an urgent shortage of large people who can move freely in the lava lake......"

"Oh?" Grim thought for a moment, it seemed that only the molten giants in the fire elemental plane fit Thork's description, and the others were either too powerful or too few in number. Grim quickly turned to the Ember Web Spider Mother Rakbeth and asked in a deep voice, "Is there a tribe of molten core giants nearby?" The number of clans should be between two hundred and five hundred, and the strength is ...... A 2nd tier is enough!"

The Ember Web Spider Mother Rakbeth thought for a moment and said softly, "I remember that it was about a 7-day walk southeast from here, and there was a tribe of molten giants there, with about four hundred people in number, and the leader was a 3rd order. ”

"Well, that's them! You find someone to show me the way, and I'll go back to ......."

After a cup of tea, Grim set off with a second-order elite-level ember web spider.

Half a month later, Grim returned to the valley with a group of tall molten giants with more than four hundred in number. It can be seen that these molten core giants are large and small, both adult and juvenile, and they should be a relatively complete tribal group.

It's a pity that the 11-meter-tall body of the 3rd order molten core giant led by him is a little crooked, and there are still obvious traces of external force on it, which seems to have been forcibly disassembled and put back together, and the energy aura revealed is about to fall to the 2nd level.

"Sock, this is my helper to get you back. It's called Nasta, and they'll be in charge of building towers in the lava lake in the future!, you have to hurry up and urge them not to be lazy, and try to finish it as soon as possible!"

Sock looked at the big guys behind Grim and immediately smiled.

The stone used to build the tower is often three to five meters square and weighs several tons, and ordinary fire creatures or engineering magic weapons cannot be moved, let alone pile and reinforce the foundation of the tower at the bottom of a lava lake as deep as fifty or sixty meters.

Such a job, such an environment, cannot be carried out without a decent helper.

Now with the Molten Giant, everything goes according to plan!

Of course, while Grim wasn't paying attention, the split-brained Sock also secretly dragged the third-order molten core giant leader Nasta aside, and curiously asked about the process of 'recruiting' it.

Almost in a 'weeping voice', Nasta recounted the painful story of how the adult transformed into a hundred-meter flame giant and pinned all the molten giant warriors to the ground and beat them up.

In particular, as the leader of the molten giants, Nasta's resistance was even more fierce, which provoked the other party to rush into rage, tearing his entire body into parts. If it weren't for Nasta's still some brains and bowing his head and surrendering early, I'm afraid that the Lord would have destroyed the entire Molten Core Clan in an instant in a fit of rage.

Fire creatures actually have this benefit.

Although they are usually temperamental and abusive, once they surrender, they become loyal and never rebel. If it is not willing to accept your rule, it will only challenge you face-to-face and decide its own destiny by victory or defeat. And he will never engage in any conspiracy behind his back, let alone go against the yin and yang, and engage in two-faced and three-sided tricks.

So, don't look at Grim's act of hijacking and looting the molten giants so rudely, and he didn't promise them any material benefits. But the moment the molten nuclei lowered their heads, they had become Grim's most loyal and determined men.

In the fire elemental plane, whoever has the biggest fist is the king.

This...... It's a creed of power etched into the soul of all fire elemental creatures!

Simple, rough, yet with a hint of cuteness......

The arrival of the molten core giant has added hundreds of tall giants to the construction site.

The bodies of the Molten Giants are not made of pure alien flames like other fire creatures, their body shells are made of huge pieces of lava rock, and the crimson magma with a temperature of nearly 1,000 degrees is rushing inside.

Their special structure gives them a strong physique and berserk strength that other low-level fire creatures don't have, and it's just too appropriate to use them as coolies!

All the molten giants lifted up the thick metal pillars and walked into the lava lake step by step. Soon, their bodies were engulfed in terrifying magma that was dark red and viscous.

In such a harsh environment, other magical creatures, even those engineering magical machines made entirely of high-flame anti-magic alloys, could not work properly. However, they moved as freely as fish in water, and instead of being burned by the magma, they became more and more energetic.

At the bottom of the lava lake, where temperatures reached almost 2,000 degrees Celsius, the molten giants trampled on the soft, molten rock, and drove the metal pillars carved with magic runes and witch circles into the depths of the rock in a specific direction.

Strange to say, as soon as these usually inconspicuous-looking metal pillars came into contact with the hot magma, the magic lines on their surfaces immediately lit up one by one. An invisible magical force field escaped, pushing the surrounding liquid lava farther away.

When the 128 metal columns were all in place in a ring, the mana field they gathered together took shape, opening a cavity nearly a mile in the center of the lava lake.

As soon as the cavity area appeared, a large number of engineering magic machines that had been waiting outside for a long time swarmed in, and began to get busy like ants in a swarm.

As Grim's current status as a great wizard, it is natural that those cheap volcanic rocks will no longer be used to build a private witch tower. The stones piled up like hills around the lava lake are not ordinary goods, but fire crystals that are quite rare even in the fire elemental plane.

Fire Crystal is equivalent to the magic crystal of the wizarding world in the fire elemental plane, and it is a high-end item of great value.

And now, they have become the lowest base material for Grim to build his own witch tower!

Pieces of fire crystals were thrown into the cavities of the lava lake, and the engineering magic machines were busy piling them up in a specific direction and shape. And while building the tower, the base of the tower is carved with intricate and mysterious magic lines and witchcraft runes.

Solid Runes, Defensive Witch Arrays, Energy Nodes, Energy Conduction, Control Witch Arrays, Magic Circuits...... Each fire crystal is a small magic circuit and a small energy node. And when they are linked one by one, they form an increasingly large rune witch array.

Etch the grooves of the rune lines, fill them with the magic mythril with the best magic channeling performance, and inlay magic gems with different functions and effects at key nodes...... Such a large and complex task can only be done by the tireless engineering magic machines and fire creatures.

If you were an ordinary person, you would have been reduced to ashes even if you couldn't even get close to the lava lake!
