In the tunnel flowing with lava, Carl controlled the floating gun and fired freezing rays that were filled with cold air forward.

The monsters left behind by the fire giants were far more numerous than they had expected.

As the team moves forward, the size of the tunnel gradually expands, and there are more and more monsters in it.

For more than six hours, Carl and his team only managed to move forward about two kilometers.

This is really too slow.

"Damn it! How many cubs did these monsters give birth to in this tunnel? We can never kill them all!"

Inside the truck, Bane became unusually impatient.

The fire giant didn't know when it would notice their actions, and being slowed down at this moment was almost equivalent to being about to be attacked by the other side.

"There's nothing we can do about it. We can't spread out the constructs in the tunnel, and we can't form a large-scale cluster for combat."

In the driver's seat of the truck, Thorin was holding the steering wheel listlessly, looking dejected.

This guy is a hidden speed racer. Once the car slows down, he seems to become depressed.

Hearing his companions' comments, Carl, who was operating the floating gun at the control hub of the truck, consoled them:

"Don't dwell on these bad things. At least we have taken a solid step towards returning to the surface.

We've done everything we can. If the fire giants come after us, we'll just fight them. I've already used all my spell slots for banishment. At worst, we can just hurt each other!"

Although the effectiveness of banishment on the fire giant nobles remains to be verified, Carl feels that even if he cannot win, he must disgust the opponent.

If you really make him angry, his mecha's hidden backup energy source will be no pushover.

Just as he was thinking this, there was a sudden commotion in the construct team ahead.

The constructs in the shape of Iron Spiders activated their spider-climbing function and climbed onto the rocks on both sides of the tunnel. They raised their guns slightly and aimed forward.

Before the drow soldier in front could pass the message back, a steel spear had already cut through the air and launched an attack towards the truck with the strongest presence.

Everyone only felt a flash of cold light in front of them, and then the attack had already arrived in front of them.

"bite!"

The tip of the spear, forged with superb forging technology, pierced into the windshield of the truck, slightly penetrating half of it.

Fine cracks instantly spread across the glass, making it difficult to see what was ahead for a moment.

“Get off first!”

After giving instructions to everyone, Carl controlled the truck to start transforming again.

Everyone took advantage of the transformation period to quickly leave, and then went directly into the constructs in the back that had no combat space.

With a "clang", Carl pulled the spear off his windshield, weighed it gently, raised his arm, and threw the spear out at an even more exaggerated speed.

The sound of sharp blades entering flesh rang out one after another. The screams of pain lasted for a few seconds and then disappeared quickly.

"Another Salamander. This kind of thing can be considered my lucky monster. Not long after I saw these guys last time, I found a way to return to the main plane of Eberron. I guess this time will be the same..."

Just as he was about to express his emotion, the fire lizards were already crawling towards him at a rapid speed.

Carl mobilized his psychic energy, and the solid nitrogen that had been ready for a long time quickly covered the area ahead.

In the rising white mist, the fire lizards let out miserable cries.

As fire elemental creatures, they are immune to non-magical attacks, and if pierced by a sharp blade, they only need to expend a certain amount of elemental energy to repair their bodies.

Low temperatures will make their body structure unstable and may even directly cause the fire element to escape from their bodies.

Of course, this situation requires the creation of a more severe low temperature. The freezing rays created by ordinary mages will only cause damage according to their corresponding levels.

As it happens, the temperature of liquid nitrogen is just right for this situation.

"Ah~, I was so far-sighted when I thought of using air compression to create an ultra-low temperature attack. I feel that this trick can be used until I become a legend."

As the saying goes: It doesn’t matter if the trick is new, as long as it works.

Hearing that there was no more sound coming from the front, Carl immediately drew out the mecha's ship-cutting sword and added the thunder sword effect to it.

It stabbed fiercely into the ground in front of it, and a shock wave quickly spread around, causing a small earthquake.

When the white mist dissipated, the fire lizard had turned into shattered ice cubes on the ground.

Watching the fate of his enemies, Carl sensed his own spiritual feedback and found that his gains this time were pitifully small.

"Huh~, no wonder not many people use fighting to improve their own levels after reaching level 12. Targets that can be easily killed cannot give you enough spiritual feedback, and those that require intense fighting may even lead to your own death. Instead of doing this, it is better to train yourself or study skills in related fields to accumulate spirituality.

Tsk, it seems that only the first 8 levels are the easiest to improve, and even then, many people still can’t make it past level 4.”

After muttering to himself, Carl measured the size of the tunnel and the mecha in front of him and found that he could almost go straight through.

Thinking that there might be fire giants chasing after him, Carl did not change back into truck form, but continued to move forward in his current form.

Simply maintaining the mecha form is not too much of a burden on Carl.

However, as the team continued to move forward, the road began to become less smooth than before.

Huge faults appeared in many places.

The construct can climb up directly, but the mecha can only be summoned by Carl using his characteristics after he detaches from it.

They moved forward for several kilometers, and just when everyone was about to stop and rest, a figure suddenly flashed on the road ahead.

"Who is it?"

Ying and Xie, who were on guard, immediately spotted the figures, but considering the unclear difference in combat power between the enemy and us, the two did not rush out, but each took two constructs to chase after them.

The tunnel, without the lava landscape, was deep and dark, but for the drow who possessed darkvision, the only difference between here and daytime was that things lacked bright colors.

Their eyes can make things visible in the dark like infrared detectors.

Hearing the angry shouts of Ying and Xie, the figure hiding in the road ahead immediately turned around and went back.

But several mind blades flashing with psychic energy flew towards the two of them.

This is a psionic blade made by a rogue of the Soul Blade subclass.

Ying and Scorpion are very familiar with this thing.

The same psychic glow lit up from his palms, and two psychic swords flew across each other, perfectly blocking the attacks of those peepers.

But when the other side discovered Ying and Xie's attack method, they stopped instead of fleeing.

"Wait! What tribe are you from? And why are you in this tunnel?!"
