The ontology is his greatest capital, and only by going all out to evolve and constantly improve his strength can he have the opportunity to deal with all kinds of possible crises.

A new organ, the Eye of the Mystic Crystal.

In Qin Song's memory, this was a very important organ. Through the [Secret Crystal Eye], you can create different types of secret crystals with different uses.

These secret crystals can directly provide witches with physical enhancement, magic enhancement, elemental enhancement, recovery blessing, and so on. It can also be embedded in equipment to give special attributes to equipment, and it is also an important ingredient for making magic circles in the middle stage.

The [Eyes of Arcane Crystals] at level 1 can create three types of primary Arcane Crystals.

Dreamweaver's Heart - Constitution Increase.

Azure Core - Mana Amplification.

Radiant Crystallization – Mixed Amplification.

The entire arcane crystal is equivalent to a gem-setting system. These secret crystals have a wide range of uses, obvious effects, and great potential to be tapped.

In particular, the magic equipment made by the spell seal compound eye can be inlaid with secret crystals with different attributes according to the needs of witches to match the characteristics.

Now the witch's magic traits are basically formed, and with the right equipment and the right secret crystals, whether it is daily production or combat, it will be improved.

Of course, there are also preconditions for proliferating [Eyes of the Mystic Crystal]: 12% completeness, 600 Mind Value, Eye of Insight lv3, and Eye of Favor lv3.

Although it is currently unattainable, the existing mind value is enough to raise the pre-Favored Eye by one level.

Eye of Favor Lv2 (can be advanced): The Deep Blue Eye that links to the Void Dream Realm can awaken the dreamwalker who is sleeping in the dream world, cross time and space, descend into the world, be loyal to you, and consume mental points. Advancement requires 10% completeness and 80 Mental Value.

For Qin Song, the Dream Walker family has brought him countless benefits. Mons the Tongue, the Sea Monster, the Deep Sea Octopus, the Bald Eagle and the Evil Nest Spider Demon all play an unexpected role.

Qin Song, who had tasted the sweetness, couldn't wait to see the true face of the new Dream Walker.

Advanced - The Eye of Favor.

Consumes 80 Mind Value.

Tiredness increased by 9%.

Eye of Favor Lv3 (advanced): The Deep Blue Eye that links to the Void Dream Realm can awaken the dreamwalker who is sleeping in the dream world, cross time and space, descend into the world, be loyal to you, and consume mental points. Advancement requires 14% completeness and 200 Intelligence.

[Summoning the Evil Nest Spider Demon]: The Evil Nest Spider Demon sleeping in the Void Dream Realm and the Eternal Dark Forest obeys your summons, wakes up from an eternal dream, descends into the world, is loyal to you, and consumes mental power.

【Summoning Rock Swallower】: Rock Swallower who sleeps in a void dream and is unstable in a rock formation, obeys your summons, strips himself from the ancient rock formation, and descends into the world, allegiance to you, and consumption of mental power.

Rock Swallower?

Stone people?

With a strong curiosity, Qin Song began to summon the evil nest spider demon. The process is similar to that of the evil nest spider, all of which are the same as the light emitted from the dark blue eyes, like 3D printing, and the outline emerges.

All right.

It's not a stone man, because the part that appears first to resemble a head has one and only organ that is somewhat similar to Qin Song's Void Chrysanthemum, like a cracked round mouth, with rock spikes in circles, the only difference is that there is no tongue.

Qin Song was stunned when the whole body appeared, this was like a caterpillar-like creature, but the body was much larger, consisting of irregular sections of stones, covered with speckled cyan, purple, or dark red moss.

The way forward is exactly the same as that of a caterpillar. He arched himself and squirmed slowly.

But the speed is also the same as that of a caterpillar, slow and hairy......

Ugly!

Blame!

Slow!

Not at all as tall as the Hive Spider Demon looks, and the only thing to be proud of is probably the sheer size, five or six meters long and wide like a circle of gasoline drums connected together.

What the hell is this?

After complaining in his heart for a while, Qin Song was still patient and began to examine its ability.

【Dream Vitality: 16】Rock Swallowers rely on Dream Vitality to survive, use their ability to consume vitality, restore vitality by digesting rocks, and when vitality reaches zero, they immediately return to the void.

Well, the use of rocks to rejuvenate is barely an advantage. At least you don't have to worry about food like the spider demon, and there is nothing else in the entire black stone collar, but there are many stones.

[Rock Expansion]: Consumes 4 vitality points, the Rock Eater devours a huge amount of rock in a short period of time, briefly increasing the upper vitality limit by 10 points, and greatly expanding in size.

What is it called?

The more you eat, the fatter you get?

If it can swell to the size of a house, it will indeed have some deterrent effect, at least lie there, it will be a natural city wall!

It seems that this rock swallower, this extremely slow speed setting, is itself biased towards defense.

[Solid Stagnation]: After consuming 5 vitality points, the Rock Swallower enters a state of strong condensation, loses his mobility, and becomes indestructible.

As Qin Song guessed, after eating fat, lie down there, and then exert strong condensation, you can form an [indestructible] city wall.

[Vomit Mire]: After consuming 5 vitality points, the Rock Swallower vomits the rock mud in his body through the giant mouth, forming a sticky quagmire.

What is this?

Vomit after eating?

What kind of weird setting is this?

There is no doubt that the Vomit Swamp is a ranged skill, and its effect is to trap the enemy and temporarily drag the enemy?

With all kinds of conjectures and complaints, Qin Song manipulated his huge body and took the rock swallower to the bottom of the seaside cliff where he often spent alone.

Prepare for the experiment.

Under Qin Song's instructions, the rock swallower came to the rock wall like a caterpillar, and the huge mouth suddenly opened and gnawed the rock wall.

There was a screeching grinding sound, and the rock shards began to splatter out, and its body swelled up at a rate visible to the naked eye as it continued to gnaw.

Qin Song touched his feet with the energy on the side of his head, holding a position that could barely be called a cheek raiser, and under his gaze, a huge hole was soon dug in the rock wall, and the size of the rock swallower almost doubled.

Wait a minute......

A flash of lightning exploded in Qin Song's mind.

This powerful rock formation destruction ability – isn't it the famous one – shield machine?

It's the ultimate tool for digging tunnels!

It can even be used for mining!

Suddenly, the ugly image of the rock swallower, which was heavy and slow, took a hundred and eighty degrees in Qin Song's heart.

Although it has no attack ability, it has practical value in construction, killing the evil nest spider demon in seconds.

Eventually, the size of the Rock Eater was fixed at four times the size, nearly twenty meters in length and four meters in diameter, and huge tunnels were dug into the rock wall at a depth of two or three meters and a diameter of about five meters.

This is the limit of the rock swallower, that is, it can no longer eat the rock.

Well, to act as a shield machine, it seems to be a little bit less interesting. In order to dig a long enough tunnel, at least dozens of them have to take turns.

Next is the test of [Strong Solidification], there is nothing special, as described. The rock swallower is different at rest, like a long big column.

According to the length estimate, the gap of about 20 meters can be closed for a short time.

In Qin Song's plan for the construction of the Holy City, the city walls were not included, which required too much material and manpower, as well as valuable time.

Rock swallowers, can be used for emergencies.

At Qin Song's command, the Rock Swallower was revived from his strong state and performed the final test of ability—the vomiting mire.

I saw its huge head, slowly arched, and from its mouth full of rocky jagged teeth, a stream of gray-black mud suddenly erupted, pouring out like a drunken person vomiting.

Puff puff......

As the vomiting progressed, it shrank in size.

When it returned to its original size, directly in front of it, a gray-black mud swamp with an area of more than ten meters was formed.

There were only 2 points left in his vitality, Qin Song gave the order to eat, and the rock swallower squirmed its bulky body, approached the rock wall, and began to eat slowly.

Qin Song, on the other hand, began to observe the vomiting mire.

Unlike what he imagined, the composition of the mire was not gravel or silt, but all gray-black mud, which seemed to be a special silt substance formed by the rock swallower who had digested the rock by some kind of magic.

Slimy, with a pronounced stickiness and slow flow.

However, the area is still too small, and if it is large enough, it can indeed form a natural barrier. Creatures that step into the mire will have less mobility.

Other than that, there doesn't seem to be any other value.

Having a general understanding of the three abilities of the Rock Swallower, Qin Song began to observe its eating. Unlike using [Rock Expansion], the eating speed is slow, and the body does not expand.

According to Qin Song's inspection and estimate, it would take at least ten minutes to recover 1 point of vitality.

It took about two or three hours to wait for the fish belly to appear white in the east, and the rock swallower recovered from 2 o'clock to 16 o'clock in his full value.

Overall, it's useful, but it's not going to be useful yet.

Just as Qin Song was about to fall asleep and return to the master clone, the favored eye behind him caught a glimpse of the vomiting mire, and in the faint morning light, it completely fell silent.

Seems to be frozen?

Congeal?

Qin Song was suddenly stunned, and almost instinctively stretched out his tentacles and tapped on the mire. It was so hard that it looked like a rock, and the whole mire was completely cemented to the ground.

Roll up a boulder and smash it with all your might.

Immediately, there was a crisp crashing sound, leaving only a shallow white pit on the surface of the mire. The rocks that originally existed in the mire were also tightly bonded with the mire.

Wait a minute!

Qin Song seems to have made a terrible discovery!

In just two or three hours, the conversion from mud to rock is completed, and it also has a strong adhesive force, isn't this - quick-drying cement???
