With experience in designing the Imperial Spirit Base and the Giant Tree City, building a small base was a no-brainer for Two One.

From the book "Dungeon Construction Guide" given to him by Tianshu, he learned various underground building repair skills, which are enough to cope with such small projects.

In particular, this time it was not a plant-based city, but just a rock building.

He doesn't need to wait for the plant to grow, he only needs to consume the energy to transform the rock texture into the shape he wants.

To this end, Eryi also specially used spell merger and spell chain to fuse multiple earth and stone spells, named [Earth and Stone Architecture], and drastically transformed the small stone settlement.

Because of the discovery and role of the "source of faith", he needs to stay here for a while.

At the same time, the previous series of battles and escape processes made him a little tired, so it was good to rest.

If he can thoroughly master this method of absorbing the source of faith, and copy it to other places after returning to it, then the speed of his rank level and strength will once again usher in a stage of explosive improvement.

The geological environment of the snowfield space is interesting, there is mud and rocky material here, but it is completely buried under an unknown layer of snow, and only the peaks at a high enough altitude can protrude the snow layer.

The rocks where the small stone settlements are located, which is actually the top of a bamboo shoot-shaped peak, may have been swept away by the snow layer above during a snowstorm, and was discovered by the snowmen to occupy it as a safety island.

There are many snow peak safety islands like this in the snow field space, most of which are occupied by some powerful large snowman tribes, and at the same time, there is not only such an intelligent creature as the snowman in the snow field space, and it is not easy to fully understand this place.

A large amount of earth and rock is continuously extracted from the ground, forming a vast foundation above the snow layer, and the bamboo shoot-shaped peaks below are the pillars of the entire rock building.

Since Eryi only needed a temporary foothold, he didn't make a big deal of the project this time, just extracted nearly 100 meters of rock mass underground to form the foundation, and the cavity caused by the back seat of the rock mass was left for its use.

After some transformation, the rock structure of the small stone settlement has been transformed into a one-legged table-like platform with bamboo shoot-shaped peaks as the base pillars.

Due to the extreme sub-elemental environment of the snow field space, the recovery speed of the two one's arcane energy is very slow, and it is impossible to carry out large-scale earth and stone construction, so after the platform and frame are built, the [Ice and Snow Architecture], which is easier to operate, is replaced.

First, he took out the [Endless Water Bottle] and set it on the rock pedestal to open the inscription leading to the hot spring, and the hot spring erupted like an angry dragon, quickly melting the snow layer it touched.

The heat carried by the hot spring water raised a hot mushroom cloud in this snowy space, almost scaring the snowmen who had never seen such a spectacle in their lives to death!

To be precise, there is no concept of "heat" or "water vapor" in their worldview.

Suddenly, they were shrouded in a warm mist, and it was as if they had been thrown into hell, and they screamed and wailed uncontrollably.

However, as ectothermic animals, the reason why their body temperature is extremely low is to adapt to the cold environment in the snowfield space, not that they do not need heat, and the use of heat by body organs has reached the extreme, and there is almost no waste.

It's just that they used to only be able to sustain their lives by eating and relying on their own weak calories, but now they are suddenly able to absorb heat and abundant water from the outside world, which quickly makes them realize the benefits.

The heat carried in the water vapor seems to awaken some kind of sleeping gene in their body, and instinctive greed absorbs the heat in it, and the moist water vapor enters the body through breathing, which also replenishes the lack of water in their bodies.

This made them feel that there had been earth-shaking changes in their bodies, and they even began to "boil with blood" and entered a strange state of rapid evolution!

Of course, the transformation of extreme environments will obviously make some weak individuals unable to adapt, just like "altitude sickness" and "deep sea sickness", which can be life-threatening if it is serious.

Fortunately, Eryi quickly noticed that the snowmen opened their mouths wide but couldn't make a sound, tried to inhale but couldn't breathe, and looked like they were about to suffocate to death, so he quickly released [Acclimatization] and [Recovery] to help them get through this stage.

Interestingly, Eryi found that both the [medical animals] for animals and the [healing techniques] for humans actually worked on the snowmen, which shows that the species determination of the snowmen is very vague, and they can be considered to be both animals and intelligent creatures similar to humans.

Seeing that the state of the snowmen had stabilized and began to enter that strange state of rapid evolution, Er Yi put his mind at ease and continued to focus on the environmental transformation of the Little Stone Tribe.

The erosion of the snow layer by the hot spring water is very terrible, and the liquid formed by the mixture of the melted snow layer and the hot spring water also provides a lot of materials for the next work of the second one.

The snow that had been driven away from the area around the bamboo shoot peaks caused a huge "sinkhole" to appear on the snowfield, and then the erosion of the hot spring water caused the snow to melt downwards to create a large space.

The melted liquid showed signs of gradual solidification in the cold low temperature of the snowfield space, and at this time, the second one made a move!

The [Ice and Snow Architecture], which is a combination of [Ice Wall Technique], [Icicle Technique], and [Ice Sculpture Technique], makes a "Cold Ice Dungeon" start from the bottom and "grow" upwards with the bamboo shoot-shaped mountain peak as the core pillar.

Thick walls of ice solidified along the perimeter, isolating different layers of ice layer by layer, and also rising upwards under the support of huge icicles.

At the same time, under the effect of [Ice Plasticity], different functional spaces are divided into each layer, which spreads all the way to the bottom of the rock platform above the snow layer and then closes and capses, forming a closed ice and snow dungeon space.

Looking at the infrastructure project he had completed, Er Yi nodded with satisfaction, then glanced at the snowmen who were cowering in the middle of the rock platform and did not dare to move, and decided to play a big game one last time, wanting to see how far his ability to control the elements could be exerted in this snowfield space.
