Over the next two days, Grim, accompanied by the beautiful Frena, toured almost all of the public areas of the Molten City.

Speaking of which, the scale of Molten City is really not small, and if you move it to the ground, it is at least the size of a medium-sized city. But when you add up the population of the entire underground molten city, there are only three or four thousand people, and seventy percent of the miscellaneous servants and slaves live in the outlying strongholds.

There are only two or three hundred wizards in the core area that can support 2 or 30,000 people, plus most of the wizards are either in the library or in the laboratory, and the occasional outing is also in a hurry. This has also led to the opening up of so many botanical gardens, gardens and other man-made landscapes in the core area of Nuoda, but there is no half of the human figure in sight.

Grim could tell that Freyna was coveting him, too. I'm afraid that if Grim hooks his finger, the glamorous witch will touch his bed in the middle of the night.

However, Grim had something in his heart, and he was not in the mood to play this kind of game with her, so after two days, the resentment in Frena's eyes could be seen by everyone.

Grim was in no mood to care about this, because the more information he knew, the more strange he felt.

This time, his 'enemy' is most likely an acquaintance!

When he asked from Frena that it was a third-order flame tiger that had been causing trouble in Molten City, his little heart fluttered a little. And when he saw the magic image that Frena had summoned from the monitoring crystal, he was even more sure that it was the third-order flame tiger Sindar who had smuggled from the fire elemental plane.

Speaking of which, Molten City has also suffered an unjustified disaster.

When developing underground ore veins, in order to avoid the invasion of foreign enemies, they arranged a large number of witch circles and wizards on the periphery. And above the ore vein, there is also the witch tower where the fourth-order wizard sits.

Under such protection, any invasion by foreign enemies is impossible.

However, to the surprise of everyone in Molten City, the enemy that emerged this time did not come from above, but from the depths of the lava sea where the mine was located.

A third-order flame tiger with extremely high intelligence emerged from the underground lava sea 2 years ago, invaded multiple underground pits in one go, and took away a large amount of strange metal ores, not to mention the lava sea, which also caused the lava sea to pour into the pit, killing more than 600 molten city miners in one go.

Since then, this Rank 3 Flame Tiger seems to have settled in Molten City, usually hiding in the depths of the lava sea, sneaking into underground pits whenever he has free time. After several times, the output of metal ore in Molten City dropped sharply, and the miners recruited also suffered heavy casualties.

As the manager of the mine, the many wizards in Molten City naturally would not sit idly by and watch a strange beast wreak havoc in their family's land. They had also formed a team to encircle and suppress the Flame Tiger several times, but each time they were escaped by taking advantage of the ubiquitous lava sea.

If the number of wizards sent out is small or the strength is not enough, they may be bitten by the flame tiger and break their muscles and bones. The number of wizards sent out, the flame tiger was also very cunning, and he turned his head and disappeared into the depths of the lava sea.

Although there are also a few fire witches in Molten City, they are only second-order strength, and searching for that third-order flame tiger in the lava sea is no less than fighting a dog with meat buns. And the rest of the wizards can barely fight with the help of the witch array to isolate the hot magma, but if they want to go deep into the lava sea, there is no return.

Therefore, these days, the wizards of Molten City have put down their work and guarded near the underground pits, which is also very anxious and miserable.

There was no choice but to release a high-level mission to the outside, hoping to recruit a powerful fire witch to capture and kill this flame tiger. Of course, worried that it would be difficult for a Rank 3 Fire Witch to deal with that Flame Tiger alone, Molten Fire City also recruited a Rank 3 Sealer.

A Tier 3 Fire Witch + a Tier 3 Sealer, plus a Tier 3 ...... in Molten City With such strength, it should be more than enough to capture that third-order flame tiger!

After learning all this, Grim couldn't help but ask the Frena to go to the underground pit to take a look.

Frena hesitated, and after using sorcery to ask the Lord Kerak for instructions, she led him to the depths of the earth.

After walking through the zigzag underground passage for half an hour, Grim could clearly sense that the concentration of fire elements in the passage began to increase sharply, and the sulfur smell in the air became more and more intense.

In a large subterranean stone hall, Grim finally saw the crowd that he hadn't seen in a long time.

This is a necessary place to lead to the underground pits, and the underground stone hall of Nuoda is crowded with alien slaves wearing shackles, naked upper body, and only a rag on the lower body.

They were all muscular, with brown and dark skin, and the upper part of their bodies was covered with grease, stains, and whip marks. Although they were tall and mighty, their eyes were full of numbness and patience, and they waited in a long line to receive tools to enter the mine.

On the other side, there is a team of alien slaves who have just emerged from the mines.

Each of them carried a wooden basket almost as tall as his own, with spiky black ore piled high inside. The surface of the ore reflects the fluorescent light projected on the cave wall, and the colorful color is very beautiful.

These are extremely primitive coarse ores, although there are a lot of metal components in the ore, but without further crushing and screening, I am afraid it is difficult to distinguish which metal components are more in it.

The people in charge of inspecting, weighing, and recording are all wizard apprentices, and on their side, there are a large number of human mercenaries who are responsible for maintaining order inside this underground stone hall. As for the two wizards stationed here, they were lying on wooden chairs on one side of the hall, drinking tea and talking about something.

Miners, slaves and subordinate mercenaries naturally enter and exit through another passage. And what Frena took with Grim was an upper passage that only wizards could pass.

Seeing the arrival of Wizard Frena, the two Rank 1 wizards stationed there hurriedly stood up and rushed to the vicinity to bow and say hello.

"That beast hasn't been making trouble again in the last few days, has it?" Although Frena looked like a bird in front of Grim, she showed full dignity in front of several low-level wizards.

"No, no ......"

"Then open the passage, and this lord and I will go to the lava sea to have a look!"

"Yes!"

With Freyna leading the way, the two resident wizards naturally had no objections.

Led by them, Grim and Freyna descended into a cold path, turning a few corners to a mirror-smooth stone wall.

The two garrison wizards each pulled out a strange wand and aimed it at the center of the stone wall. With a strange wave of sorcery, a large stone gate emerged from the center of the originally blue-gray stone wall. Then the stone gate silently slid to the side, revealing the dark red and viscous magma fluid outside the light film.

As soon as the door opened, a film of energy light rose from here, blocking the hot and churning magma from the outside.

Despite this, the temperature in this passage also began to rise sharply, and soon reached more than 100 degrees.

If ordinary people are in such an environment, I am afraid that the flesh and blood of the whole body will be cooked before they can get out of three or five fingers. Even the two resident wizards couldn't help but start wiping the sweat from their foreheads frequently.

With a sweep of his eyes, Grim's chip had already scanned the stone door and the dark red lava sea outside the door.

"The environment in the lava sea is complicated, let me accompany your Excellency to walk inside!" Frena said with a smile.

Grim shook his head and said indifferently: "I won't go far, just explore the environment here nearby, so that I can be more sure when I fight later......"

After that, he no longer was polite to the other party, and stepped in front of the light film in a few steps, and a layer of pale red magic light suddenly rose on his body, and then slowly passed through the light film and sank into the surging lava sea.

Although the sea of lava in front of you seems to be stationary, in fact, the viscous magma fluid is constantly in a state of rushing and flowing. It's just that the entire space is filled with dark red hot magma, which gives people a sensory illusion.

As soon as Grim wore out of the light film, the light mask on the surface of his body suddenly withstood the pressure of thousands of pounds. The hot magma of the bones and flesh was desperately squeezing towards the center from all directions, and Grim was in the middle of it, so naturally he had to bear this strange force.

Grim hesitated for a moment, then slowly put the light mask into his body again, and the hot magma around him instantly crowded over, enveloping him tightly.

The hot lava and the warm skin touched together, and instead of making a sizzling and scorching sound, it sent out streams of heat into Grim's body, making him almost sigh in comfort.

If he was still Tier 2, he might be able to withstand the extreme heat here, but he wouldn't be able to withstand the terrifying hydraulics. Now after advancing to the 3rd order, the affinity between this body and the fire element has reached an extremely high level. At this moment, I suddenly plunged into the lava sea, not only did I not feel the slightest pressure, but I felt a sense of pleasure like a fish in water.

However, Grim also has to separate a stream of flame energy from his body to escape to the surroundings to protect the witch robe outside his body, otherwise such a terrifying high temperature burn, his own people may be able to stand it, but the clothes outside his body must not be able to stand it.

If you don't want to run for the fruit, you can only use the flame energy to protect your clothes!

Other wizards may have difficulty navigating the lava sea, but a fire wizard has no problem with that.

Grim smiled, and his entire body immediately gathered and became invisible, turning into a humanoid flame that quickly shuttled through the viscous lava sea. Relying on the flames at different angles, Grim rushed left and right in the depths of the lava sea, and the speed was even several times faster than flying in the air.

For a fire witch, the flames are truly his home turf!
