Six days later, on Christo Island, deep in the second layer of the underground fire veins of Red Sand Ridge,

Three figures appeared at the edge of a huge cavern, and the scorching breath poured out from the depths of the cavern and entered the second layer of the mine, like an invisible flame, raging through the mine.

The three figures were shocked by this blazing air current, and their bodies swayed slightly, and they hurriedly stood firm against the cave wall.

On the left, there is a zombie with skin like iron, on the right is a girl with a small body and a warrior's costume, and in the middle, it is Merlin who has just finished a trip to Lennon Island.

If the moon is full, you will lose!

She had already gained so much from Lennon that there was no need to stay any longer. As for the materials needed to advance to the next level...... There was no obstacle for her, it was just a matter of timing.

After the underground fire vein merged with the clones and Victoria, Merlin fused the soul crystals for them as soon as possible, and then quickly got rid of the wizards in the Ash Academy and headed for the deepest part of the underground fire vein.

"Longbottom. Merlin gestured, and the zombie lord walked towards the cave with a heavy flail in his hand.

Merlin glanced at the bottomless cavern and said in her heart...... If nothing else, this cave was a passage that was blasted out by the wizard trapped in the underground fire vein when the mutation occurred.

She calmly followed behind, holding the Ink Shadow Sword, and the defensive witch weapon was in a state that could be triggered at any time, and once there was a change, it could be defended at any time. There was some danger in this, and she wasn't too worried. Both Longbottom and Rosa have successfully fused soul crystals, and their strength is enough to ensure that Merlin will not lose her life here in any bad situation.

Going down from the underground cave is a naturally formed giant underground karst cave, which is by no means comparable to the second floor of the cave dug by manpower. If you rely on manpower to dig, it will not take tens of thousands of people and 100 years to dig out such a huge underground cave.

In this underground cave, there are even low and undulating mountains, low-lying areas, underground rivers, lakes, and deep pools, and the scorching breath swept in, and the fog in the cave immediately steamed. The entire cave is red, and no matter how good your eyesight is, you can't see the end.

And in the far distance, a dazzling river of red magma can be faintly seen, rolling and flowing. It is this river of red magma that reflects the entire underground cave in red. The heat wave rolled in, and after a while, Merlin and Rosa were sweating.

Due to the special geographical environment in this cave, it is full of fire attribute energy particles, which are very alive and lost, and ordinary plants and animals cannot survive here at all. But some creatures that also have fire attributes are like fish in water here. All kinds of strange flowers and plants and trees with the thickness of the bowl mouth are almost everywhere.

Fire wood, the finest material used to make the fire wand. Some special parts can also be made into disposable witchcraft. There is also a flame flower that seems to be shrouded in a layer of flames, which is the main material used to make the fire crude elixir. These materials are not visible at all on the surface of the earth, and can only grow in places where fire attribute energy particles are highly active.

What does a person do when they enter Baoshan?

Of course, it's a hard hug!

Merlin summoned the undead pets, and used the witchcraft if they were obedient, and the ordinary pocket if they didn't have the equipment. Just pick the best lot and harvest it directly. In front of it is the magma river, and the earth fire magma will be strong at that time!

She looked up at the cave in all directions...... The vision here is not very good, the fog is too heavy, a piece of red, separated by more than ten meters, it can only be seen when an outline, Zhang Jiayue in order to see more carefully, simply cast the 'true eye', so that you can see more clearly, all objects are in the form of energy.

With the Grinder and the Golem picking up the materials, Merlin is now calculating the danger around her.

There are a lot of fire attribute materials here, and even she found some very rare ores, and after scavenging the best materials, Merlin still set out on the road with three people, heading towards the magma river.

Here, in addition to those rare materials, the most common are powerful beasts...... The vast majority of these beasts are demonized, temperament is irritable and cruel, at the beginning, the contract creatures acted in groups, killing a large number of demonized beasts, and after Mei Lin put away most of the contract creatures, these fierce beasts suddenly began to be active again, fortunately, the most powerful of these creatures is only equivalent to the strength of a third-level wizard, although it can bring a little trouble to Mei Lin, but it is far from a threat.

Although most of the contract creatures were put away, the danger factor of Mei Lin and the others was decreasing - there was the illusion output of the illusory goblins, and the fierce beasts that were galloping around them did not even notice that Mei Lin and the others were passing quickly not far away.

Merlin felt a little dry, she took out the water bladder and drank it in a big gulp, seeing Rosa looking at it with blank eyes, she casually took out another water bladder and threw it to her...... "It's still an undead pet, and Longbottom is still full of physical strength, and I can't even see a bead of sweat."

However, they did not have time to rest. Now they should be the first wizards to enter this underground cave, and they must scavenge as many good things as possible before a large number of wizards enter the cave.

About two hours after Merlin and the others left the cave, three wizards from the Ember Academy also found the cave...... As long as you follow the source of the scorching breath, you will find this place sooner or later. All three wizards were a little embarrassed, and they didn't know if it was their own or someone else's blood.

Although the wizard's robe has a clean and simple protective circle, it is unlikely to be refined like armor after all, and small attacks can be blocked, but the attack power is slightly larger, and their protective effect is not enough. Whether it is hunted down or hunted down, being able to survive is the best outcome.

The three wizards cautiously inspected the area around the cavern, and after making sure there was no danger, they also entered the underground cavern. Suddenly, they were stunned by this majestic and vast underground cave.

However, they soon returned to normal. These wizards of the Ash Academy have experienced life and death many times along the way, and they have been able to successfully reach this place, and their strength, experience, and scheming have definitely reached a certain level. The leading wizard did not rush to explore the place, but gestured to the other two wizards for a while, and then led them to hide behind several huge stalagmites under the cover of the red mist.
