The suppression of the blood-ridged rock newt lasted for nearly a month and a half. It is difficult to see the trace of this underground indigenous creature within a radius of more than 100 kilometers. Perhaps there are some fish that have escaped the net. After this ruthless and cruel killing, even if these ugly "four-legged snakes" have low intelligence, they will form a deep fear that is imprinted in their bones and dare not get close.

After conducting preliminary environmental exploration, the heat and darkness space extending from Miyan Village to the depths of the ground is not the whole of the entire underground world, and it is not even a corner, but just a very inconspicuous small corner.

To be precise, it should be a small hole attached to the underground world.

The 3rd Squadron of the Security Corps, who explored more than 100 kilometers or more than 200 kilometers in various directions in various directions, and repeatedly hit the walls, finally discovered that it was no longer a thick rock wall that connected the ground and the dome, but a cave entrance leading to a wider unknown space. Looking into the distance, you can vaguely see the bright "sky (dome)", which seems to be more like a real world.

The dark space where the underground passage exit is located seems to be just a barren land without much vitality.

The source of dry and hot air is a magma river about ten steps wide across the outlet. After the air is heated, it becomes dryer and hotter. The hot air brought by the rise of the air flow surges into the hole about hundreds of steps wide.

On both sides of the slowly flowing dark red magma are large charred black igneous rocks, stacked layer by layer, twists and turns, like the cut surface of an Italian thousand-layer cake.

If you are not careful, you will step on the air and twist your feet until your feet are light, and this terrain will not be able to handle horses.

Perhaps it was because the cooling process had been going through a long time. The crystal grains condensed by these scorched black rocks were extremely large. The small ones were no different from sand. The large ones were comparable to peanuts, colorful and crystal clear.

You can easily pry off more than a hundred crystals of different colors for identification. Most of them are common crystals such as crystals, feldspar, olivine, calcite and mica. Not only can you see them everywhere, but you can even find some obsidian with pure texture.

Although these unexpected gains are not worth much, a few of the particles are larger and pure in appearance, but they are enough to be processed into the lowest-grade gemstones.

Perhaps it is precisely because of this magma river and the strange black igneous ground on both sides that external creatures cannot enter, and the blood-ridged rocks are also isolated from the world.

Although there is a channel connecting the surface world, due to the existence of the monster Qingxue Mingbiao and its own mental retardation, the blood-spined rock-buckling can only rely on eating the stubborn vitality of the moss, insects and even the flesh and blood of the same tribe to make a living, forming an extremely single ecological environment. The amazing parthenogenesis ability is also forced out, but the ability to sacrifice evolution and environmental adaptation is the ability to adapt.

After the sand table model of the rock pillar space completed the last step, Dragoon Magic Industry realized how lucky it was.

This thick rock pillar is lined with a large area, like a maze, which is not completely closed, but a place where you can attack and retreat and defend, with extremely high military value. It is almost a bridgehead given by the gods to penetrate deep into the underground world, and its strategic significance is immeasurable.

The geological exploration report was also completed quickly. In fact, the gold dragon and the monster Ferrero join forces to be the best miner combination. Both metal and non-metal mineral deposits can be found without any omissions.

The rock column space does not contain much minerals. There are only a small amount of coarse-quality star fluorite. It can emit light because the ambient temperature is relatively high, which converts the heat in the air into weak fluorescence. Even a piece of head size can only illuminate within one foot of the range, and it will become dimmer even further away.

Dragoon Magic Industry has invested a lot of money in order to develop resources in the underground world and build its own dungeon. Although there are not many resources that can be directly utilized after opening the channel, it still discovered many profit points.

The stable dry, hot and dark environment is suitable for some plants with strict growth requirements. By building special plantations, you can continuously obtain precious medicinal resources. At the same time, the native bryo fungi in this environment are endemic species. The medicine saints of the Slan Empire quickly found their value. They can carefully prepare special bathing agents, which are very suitable for cleaning the muscles and muscles of warriors and significantly enhancing their physical fitness.

However, more resources are still in the vast underground world outside, which requires crossing the magma river that emits amazing heat.

The rock pillar maze was not used by the Dragoon Magic Industry. Perhaps out of confidence, after clearing out the road to the Magma River, telephone poles and street lights were directly set up. As long as you follow the lights, you can easily pass through this intricate maze.

With the support of sufficient supplies, it is not much difficult to cross the magma river.

It took only one day to build a magnificent arch bridge with hard and heavy refractory bricks. The huge main bridge hole spans above the magma, and a layer of silver steel plate is also installed in the inner circle, further weakening the impact of the thermal radiation of the magma on the bridge body, and at the same time improving a certain amount of heat dissipation ability.

Although the dark red magma that emits a rolling heat wave looks very scary, its temperature is far from comparable to that of a real steelmaking furnace. The refractory bricks that are usually used for smelting will not soften or deform at all even if they fall into the magma. However, the people and animals coming and going to the bridge deck are not steel bars and iron bones, and can withstand the scorching under their feet.

Although the bridge hole is arched, the bridge deck is very wide and flat, and the slope is slowly lowered, extending to 300 meters away from both sides of the strait.

After the arch bridge was built, the warriors of the security team who had good news put a few eggs on the bridge deck. Unexpectedly, it was cooked in less than a quarter of an hour. If a steel shovel was extended out of the bridge and poured a few drops of oil, they could fry a few poached eggs with delicious flavor.

Dragoon Magic Industry has built extremely strong fortifications on both sides of the Taiwan Strait, with six towering and sturdy large edges and corners reaching the bridge body. Any creature trying to rush onto the bridge without permission will be subject to the most fierce fire attack, giving full play to the advantage of the geographical advantage.

"Mr. Morin! The 3rd Squadron was attacked and requested emergency support."

Lin Mo, who had just returned to the ground with the Golden Dragon, suddenly received an emergency call from Manager Bambi in the Rock Pillar Space of the Underground World.

"Who is the attacker, a monster or a wise creature?"

Lin Mo had just filled the space-based alchemy memory on his right wrist.

"It seems to be some beetles, flying giant beetles, their screams can interfere with the call. Adult, you'd better be faster, the 3rd squadron may not last long."

Manager Bambie's tone was very anxious.

The force of the dragon magic industry deployed to the underground world attracted a security team. If a squadron was damaged, facing such a wide space, it would be even more powerless to control it.

"Okay! I'll arrive as soon as possible."

Lin Mo dialed Yin Longyou's call.

"You, there is something urgent! Come to Miyan Village!"

“Arrival now!”

Five minutes later, Lin Mo and the Yinlong who had just arrived took away a large amount of supplies and disappeared in the empty space of a silver fog.

Due to unknown reasons, many geological structures will seriously interfere with the sub-phase jumping ability of the Silver Dragon clan, making it unable to use its own talents to directly enter the underground world.

However, since you have mastered the reliable channel to the underground world, the sub-phase jump of the silver dragon has become useless. Even if the talented space capacity of the same clan is far beyond the talented space capacity of the same clan, it cannot compare to the long flow of the passage transportation.

With the accurate channel model, Yin Longyou and Lin Mo corrected their footing points several times in the middle, spanning nearly 400 kilometers in the shortest time and appeared directly in the rock pillar space.

"3rd Squadron! I am Morin!"

"Mr. Morin! Oh!~~~~~~"

As soon as Lin Mo answered, he heard a harsh whistle in his ears. He frowned and quickly closed the call.

When it is connected again, it still screams.

After repeated several times, even starting the filter module is still useless.

He finally confirmed that this was not electromagnetic interference, but a real sonic attack, and the anti-interference function of the "Dragon General" can do nothing about it.

"You! Jump twice, there is a magma river in front of you."

The Dragon Knight glanced at the thick rock pillars not far away, shrouded in lights, and pointed in one direction.

In the underground world, the compass has completely lost its function. The only thing that can be relied on is the gyroscope. The direction coordinates set in the underground world are basically maintained in synchronization with the ground.
