Two days later.

In front of the exit of another passage, Grim silently examined the flowing dark red halo transmitted through the light film. Faintly, it seemed that you could still hear the rumbling sound of the fluid magma surging beyond the light film.

"Lord Grimm, this operation will depend on your support a lot!"

The two second-order fire witches sent by Molten City were a pair of brothers and sisters, and the slightly older brother had a serious expression and briefly introduced the situation of the two of them to Grim. The younger sister did not say a word, and followed closely behind the elder brother.

However, from the eyes she secretly glanced at Grim several times, you can find that her personality is more lively, and her appearance is quite reasonable.

"Well, everything happens when it happens. Grim simply agreed, and took the lead in stepping out of the light film.

These two second-order brothers and sisters didn't dare to walk directly into the lava sea like Grim's stingers, but quickly cast spells, each blessed with a large number of elemental auras, and drank some potions to quickly restore their energy by the way, and then carefully stepped out of the light film.

If a Tier 1 wizard is just a beginner who has just glimpsed the Hall of Truth, then a Tier 2 wizard is a seeker of truth who has entered the Truth.

The sea of lava in front of you is already 300 meters deep from the ground, and it is difficult for ordinary wizards to survive here. And although these two fire witch brothers and sisters can withstand the scorching flames and the high pressure of the slurry here, they are consuming their strength every moment.

At this point, they are nowhere near as casual and natural as Grim appears.

Those who can become fire witches have naturally completed the elementalization of their bodies.

In the dark red surging hot magma, three nearly completely transparent flame figures glanced at each other and silently dived to the predetermined position.

The location of the underground pit of Molten City, in order to avoid the invasion of magma fluids, countless defensive witch arrays have been solidified. Unfortunately, many of them had been destroyed by that Rank 3 Flame Tiger, causing huge losses to the inside of the mine.

Although the magma in the pit was emptied afterwards and the defensive array was repaired, the entire defense system of the pit was also scattered, and there was no longer the previous coagulation.

This time, the Rune Array Master in Molten Fire City started from here, leaving a seemingly unintentional loophole in the mine's defense system to lure the Flame Tiger into taking the bait.

However, such a trap can't be too straightforward, so it's unknown whether that flame tiger will take the bait or when!

The task of Grim and the two Molten City Fire Witches is to ambush in the depths of the lava sea in advance, and wait until the Flame Tiger is ambushed before rushing out to block the other party's retreat.

Such an idea is easier said than done, so the two Molten City Fire Witch brothers and sisters followed closely behind Grim, and their hearts were also apprehensive and difficult to be at peace.

As second-order fire witches, the strength of their brother and sister is naturally extremely strong, and after turning into a flame human form, the means of hiding and hiding are also amazing.

However, when their attention was on the third-order Legendary Fire Witch, they couldn't help but secretly admire: "The Legendary Fire Witch is worthy of being the Legendary Fire Witch......

The two sides were so close, but they couldn't sense the slightest difference from the flames of Grim's incarnation.

Like the burning flames that can be seen everywhere in a sea of lava, Grim walks slowly through the dark red slurry. If it weren't for the fact that the brother and sister could see each other's existence with the naked eye, I am afraid that they would not be able to distinguish Grim from the flames in the background.

The three of them made a quick journey through the sea of lava, and soon came to the predetermined location.

Here, a spindle-shaped rune boulder with a thickness of three meters and a height of five meters is slowly moving in the sea of lava. Sensing the arrival of the three of them, the strange inscriptions etched on the rune stones lit up one after another, flickering with an uncertain halo.

The fire witch stepped forward and leaned on the elemental barrier supported by the rune stone with her transparent palm, and with a chant of spells, the rune stone shook slightly, and the outer elemental barrier suddenly split, revealing a small portal on the surface of the boulder as hard as steel.

The three of them did not hesitate and quickly penetrated into it.

The space inside the rune stone was not large, but at this time, it was crowded into three wizards, and it immediately seemed a little crowded.

When the runestone entrance was closed again, the three of them sat cross-legged inside, barely able to fit it. However, if the three of them move a little, they will inevitably be touched and physically touched.

The rune stone was originally part of the vigilance system that Molten City had placed in the lava sea to detect movement on the periphery of the mine, and if the Flame Tiger really wanted to sneak into the mine, it would definitely avoid it.

So the three of them are hiding here, but they are safe.

In order to avoid embarrassment, the two fire witch brothers and sisters could only close their eyes and recuperate, silently waiting for the message from afar. Grim, on the other hand, looked around, looking at the runestone he was in.

The inside of the runestone was not empty, and countless strange runes and witchcraft inscriptions were densely etched into the surrounding rock walls.

Grim saw it very clearly, some were energy storage runes, some were energy-absorbing runes, some were protective witch arrays, and some were alert runes...... Although he doesn't know much about the mechanism of rune stones, he can understand a lot of things from these strange wizards alone.

As part of the vigilance mechanism, simple rune stones are too monotonous and rigid, and it is difficult to defend against the enemy's covert invasion without leaking. Therefore, the runestones here are usually guarded by wizards.

Then, with the tirelessness of the runestone and the powerful spiritual scanning of the stationed wizards, the combination of the two makes it extremely difficult for ordinary foreign enemies to sneak into the inner line unknowingly!

Just like now, Grim could clearly perceive that the rune array etched on the rune stone rock wall was echoing with the two second-order wizards at all times. The two complement each other, and the combination of breath and ability makes their spiritual perception ability qualitatively improved.

Grim couldn't help but ask, "Did you buy this runestone, or did you organize and build it yourself?"

The Fire Witch siblings opened their eyes and looked at Grim curiously.

Eventually, it was the elder brother who spoke.

"The basics of the runestones were purchased from the Silver Alliance, but the refining seems to have been done by Lord Dorian himself! After all, it is impossible for one's own vigilance and defense system to completely fake others, or to build one's own safer ......"

Grim nodded silently and closed his eyes again.

The two siblings looked at each other, shrugged helplessly, and once again shifted their attention to the detection and scanning of the surrounding lava sea.

However, it didn't take long for the fire witch to open her eyes suddenly, and whispered in surprise: "There's movement in the mine! That flame tiger seems to be destroying the rock wall of the mine......"

Grim's eyes widened, and a thoughtful look appeared on his face.

…………

At this moment, on the periphery of the underground pit of Molten City, a flame tiger is frantically destroying the rock wall.

Unlike the rocks of other regions, the rock walls on the periphery of the pit, although soaked in terrifying magma fluids, do not appear to soften or disintegrate. The volcanic rock here is as hard as steel because of the large amount of metal involved, but it can withstand the erosion of high temperatures and heat for a long time, so it is extremely difficult to destroy.

But the flame tiger didn't seem to care about it.

It stood in the surging magma, wielding huge claws of flame, thumping through the steel-solid rock walls.

No matter how powerful the wizards of Molten City were, it was impossible for the entire mine pit that spread for dozens of kilometers to be under the protection of the Rune Witch Array. Therefore, the most dense places of the Rune Witch Array are often concentrated in the weak points and entrances and exits of the pit.

But today, the flame tiger, which had disappeared for a while, did the opposite, and instead of trying to sneak into the mine, he chose a place that wizards couldn't take care of outside the pit and dug frantically.

The Hengjin Essence that has been continuously absorbed over the past few days has also made the Flame Tiger's elementalized body a little different. Each time the sharp tiger claw composed of pure flames strikes, it not only contains powerful fire power, but also carries a roaring wind, showing terrifying physical attack power.

As soon as the claw went down, a pit half a meter deep appeared in the solid steel rock wall, and the bottom of the pit was a terrible crack as dense as a spider's web. The Flame Tiger dug down without stopping with one claw after another, and in an instant, he dug out a huge pit seven or eight meters deep on the rock wall.

At this rate, it won't take half a day's work for the Flame Tiger to dig through the rock wall of more than 30 meters and dig directly into the pit tunnel.

Such a scene was obviously a bit unexpected by the higher-ups of Molten City, and it also made several third-order wizards behind the stealth unable to sit still any longer.

In a violent wave of magic, two Rank 3 wizards appeared in the lava sea at the same time.

Unlike Grim's incarnation of the fire elemental and the fusion of the lava sea, the two third-order wizards, one of whom is a poison and the other is a rune master, are obviously not suitable for fighting in the lava sea.

However, the current plot is a little different from the previous one, and the flame tiger did not step into the trap of the witch array, which also made the two high-ranking members of Molten Fire City only make a move with hatred, hoping to lure it into the trap range.

The Kaylak and the Dorian wizard stood in a giant rolling stone ball, forcing the obstructive magma fluid away and angrily charging at the Flame Tiger.

The two sides immediately engaged in a desperate fight on the periphery of the pit.

However, when it comes to fighting, in fact, the two wizards are more on defense, trying to defuse the endless attacks of the 3rd Order Flame Tiger.

In the lava sea, the combat power that the Tier 3 Flame Tiger can exert is simply amazing.

Its 3-meter body flickered around the stone ball, and every time it appeared, it was accompanied by a huge roar and a fierce tiger claw attack, which shook the earth element on the surface of the stone ball.
