In the dark underground, nothing is more annoying than the undead.

For the heavily-fired rat army, no living creature can go back and forth a few times. The only thing that can rush to the army with two hundred magic guns is the corpse of the monster.

However, there is a kind of monster that encounters the mercy of the army. The injured cave lizards are gathered together to receive unified treatment and transformation education.

The giant lizards expressed regret for their spiritual shortcomings, but they had to surrender under the threat of many guns.

There were even some thirsty rats who were already harsh and poisoned the female giant lizards. The male giant lizards dared not speak out, but felt that the color of the scales was greener.

After solving the dangerous monsters entrenched in the cave, the rats began to deal with the troublesome undead.

These things are everywhere, and no one knows why they gather in large quantities underground. The rat people only know that cleaning them is simple and difficult.

The firepower of the magic rifle is quite considerable compared to the crossbow arrows. As long as you hit the head, a bullet can often completely return a dead soul.

But this is just an ideal situation. A magic rifle is ultimately a smoothbore rifle. Unless it is within 100 meters, its accuracy will be that way.

Hunters and grenadiers are always inevitably trapped in melee battles. Fortunately, although there are many undead, they are not skeleton soldiers with swords.

A rat man complained, waving the hammer in his hand again, smashing the head of a dead soul into pieces.

She only knew that as the expedition deepened, the temperature below became more and more intense.

After the undead was solved, the army of rats continued to go deeper. As the depth increased, the next cave creatures were obviously stronger. The rats cleaned up a large group of mother spiders and completely destroyed their nests. At this point, the army's ammunition was almost wiped out.

According to the principle of magic pressure, Ictor even had a guess.

"By the way, the temperature, the prophet told me before he left!"

“So hot.”

Magicians have imagined such things. In many novels, that kind of existence is described as "earth veins", but this thing has never been found.

This is a shaped magic crystal similar to a stalactite structure. Its grade is unknown but its reserves are.

It can only be described as scary.

"Heat is a good thing, the Prophet said, which means that the core of the planet is not cooled, and with the help of the molten mantle, relative movement can occur between continental plates, which helps the progress of geological activities.

Siroleman looked at the crystal clear structure in front of him obsessedly. Obviously, this is not the whole of the underground cave. The first magic crystal cave discovered was probably not very high.

These rats are the most elite soldiers, veterans of Li Zhan, Scarven super rats, and all single shots are all kids, and two rats are even more intriguing.

Under the guidance of the Lani Rune Gloss Stick, the Rat Man Expedition began to investigate the locations that the adventurers could not reach.

Rat people often think about the bone frames under the Tomb King. They are not only large in number, but also equipped with weapons and shields in large quantities.

It wouldn't be strange if they had industrial productivity like Scarven society, but if a group of less intelligent skeletons could be well equipped, their productivity would be intriguing.

The formation conditions of the Sage Stone must be more complicated. Only a few lucky ones will be turned up to a position that humans can reach, but if it is a liquid magic river or even an ocean, there may be hope.

"Then we're very lucky, at least we live on a pretty hot ball."

Most regular troops will stay in place and wait for supplies, while smaller expeditions will go deeper.

To be precise, this is the remains of an ancient dragon.

Logically speaking, although there is a lack of organic matter underground, there should always be a few powerful monsters under the pressure of high demons.

Otherwise, our world will likely be covered with sand, because then there will only be geological effects such as weathering and erosion on the surface, and the ground will most likely be covered with sand."

The atmosphere of adventure suddenly became weird, until a rat man accidentally bumped into a giant creature, completely igniting the tense atmosphere.

The rats around were also repeating similar movements, and the entire army was divided into three parts: the combat group, the rest group and the preparation group.

He once asked Ictor about a science called "geological movement". Perhaps the magic crystals and gems in the lower layer would be turned up for some reason, but the possibility is still slim.

Siroleman said that because extraordinary creatures like dragons have a very slow decay rate, for a native dragon, a thousand years is not enough to corrupt the skin and scales on the surface.

Siroleman recalled it strangely, Ictor seemed sure that as they went deeper, the cave should be hotter, not colder.

Each layer is the most difficult to clean up these things, and the number of undead often ranges from hundreds to thousands.

Rani said, leading the team forward.

The well-equipped rat man encountered the poor skeleton under the ground, and the result was naturally crushed.

The hunting rats brought the mages closer. When the fluorescent light of the rune blade shone on the giant creature, Lani couldn't help but curse and swear.

Along the way, there were gems and magic crystals, and the temperature gradually increased. But strangely, the way was only full of undead, but no more powerful monsters were encountered.

"This is an ancient dragon!"

Rani didn't care about these things, they were studied by the Tumen Magician.

Under the flow of the rat army, the number of undead is decreasing rapidly.

"It's not my death recently, this thing must have been dead for a long time."

"To be honest, this is quite tiring."

The battle group consists of rat people equipped with bayonets and hammerheads. The bayonets are responsible for jamming the undead and then giving a fatal blow to the hammerheads.

"Captain, you have to look at this."

Not long after the expedition went deeper, the expedition team had discovered many magic crystals.

"I'm right, Captain Lani, this entire cave is made of magic crystals!"

Perhaps just like a neutron star, magic may produce degenerate states or pure magic liquid or solid crystals when it is compressed by extremes.

A skull alone is enough to be comparable to a huge rock. This huge thing successfully interprets how exaggerated the high magic pressure can swell the body of a creature.

The remains of the holy dragon located in the former Beisai Empire are enough to prove this, it looks like it is asleep.

"The death of this dragon is nothing, the key is these."

Siroleman picked up some dragon scale fragments. These did not belong to the difficult ancient dragons to be classified, but the modern cave-dwelling black dragon.

In addition, there is a small piece of dragon-like minced meat.

"I'm afraid, this is the real trouble."
