The flying bird and war beast behind Yan Yangtian launched again, flew into the ground silently, followed the map opened up by Li Yao, carefully searched again, and transmitted back a large amount of image information.

"Visually found no demon beast lair and trap traps, but everyone still has to be careful and vigilant, let's go down!"

In the mine, there is a minecart system that goes straight underground, but it is also brittle after thousands of years of wind and frost.

Li Yao checked it, and the difficulty of maintenance was not high, that is, it was necessary to collect materials everywhere, and it would take at least a day to completely repair it.

They simply gave up the minecart and gathered in a group, and the captain Hong Tong activated the gravity supernatural power, adjusting the gravity within five meters in diameter to one-fifth of the standard gravity, equivalent to one-third of the Tianyuan Realm.

Under such gravity, everyone felt that their bodies were as light as swallows, and the power rune array of the Guò Crystal Armor was delicately manipulated, like six bundles of feathers, floating towards the bottom of the mine, and occasionally stepping on the cave wall, they could obtain a lot of acceleration.

"Wave! Wave! Wave! ”

As he descended, Li Yao released more light waves and divine thunder, scanning every underground crevice and working surface, making the three-dimensional map clearer and richer.

Soon, the steep mine path became gentle, and more forks appeared on the left and right, and in front of them were the wreckage of several abandoned minecarts as they approached the ground.

Under the faint light of the crystal armor, the walls of the cave in all directions reflected thousands of colors, like a solidified rainbow, and the rocks grew like crystal clusters, which was incomparably magnificent, like a luxurious and splendid underground palace.

In the crevices of many crystal clusters, there are also cyclops mushrooms.

Unlike their counterparts on the ground, these underground giant mushrooms are slender, curvaceous and covered in green scars. There is also a faint purple mist around the body, like a light song and dance, swaying slightly.

On the Xuanbing Star, there are more than thirty kinds of heavenly and earthly treasures, such as Colorful Stone and Thunder Spirit Diamond.

The light is emitted from these ores.

However, most of the ore is also produced in the Tian Yuan Realm, and the volume is too large. It's too difficult to mine, and there's little point in bringing it back.

All they needed was the small, high-value Nine Aperture Stones and Melting Spirit Crystals.

"Go ahead, pay attention to scanning these underground giant mushrooms, if the green spots on their bodies have red threads, it means that there are nine holes and melting spirit crystals next to them, be careful, keep the internal circulation system functioning normally, these underground giant mushrooms are ten times more hallucinogenic than the one-eyed giant mushrooms on the ground. Even the foundation building monks can easily fall into the illusion! ”

Before Captain Hong Tong's words fell, countless bands of light suddenly floated out of the rock crevices, as if they were hundreds of translucent fluorescent ribbon fish, floating in mid-air, exuding a cold air.

The temperature in the mine suddenly dropped by more than ten degrees.

Even with the protection of the crystal armor and spirit pattern, Li Yao still felt a chill that froze into the bone marrow.

These "ribbon fish" have no substance, but they seem to have a certain amount of wisdom. In the two holes in front of his body, two beams of dark blue ice and fire shone. Six Star Rangers were quickly locked.

"Did you see that?" Li Yao asked in a low voice, making sure it wasn't his hallucination.

"I saw it, not an illusion, but a spirit called 'Fierce Ice Spirit'."

"Swallow" Yan Yang Tianfei said quickly, "It is easy for this kind of fierce spirit to appear on the ancient battlefield, they are the last trace of killing and destroying left by the war dead. Combined with the battlefield environment, the special spirits produced are not ghosts, but they are more aggressive than ghosts. ”

"The underground of the Xuanbing Star is full of ice. Some of the ice demons will leak out of the tiny crevices, and when combined with the last trace of killing intent of the war dead, after thousands of years, they will become fierce ice spirits! ”

At this time, the fierce ice spirits in front of him had gathered in hundreds, illuminating the entire underground world into a blue patch.

They let out a silent scream, but it was a strange feeling in Li Yao's mind like a steel nail rubbing against glass.

The fierce ice spirit shrank and pounced on the bronze team like a sharp arrow!

"Tactic No. 6 against ghost-like enemies, unleash!"

Captain Hong Tong roared, his fists slammed into both sides, and his fists knocked down a large number of ore fragments from the cave wall, which were sucked in front of him by his gravity control powers, forming a loose gravel formation.

Many ferocious ice spirits collided head-on, freezing the ore into ice mounds, shattering after a few "clicks", and the Xiaoice beads "crackled" and fell to the ground.

But because of this, a large amount of spiritual energy of the fierce ice spirit was consumed, and the eerie and cold meaning quickly dissipated.

Ding Ling took advantage of this opportunity to take the lead, and the Red Shadow Battle Armor outlined a scorching red glow in the darkness, and his arms transformed into two fire dragons, one red and one blue, roaring out, devouring all the fierce ice spirits.

The ferocious ice spirits let out a terrible scream in the flames, and they all melted into a blue liquid.

A few fierce ice spirits tore through the fire net and continued to move forward, but they were beaten to pieces by the "bullet shell" Leng Ziming with a burst bullet engraved with a flame rune.

From the beginning to the end, only two fierce ice spirits rushed in front of everyone, but they were also cut into seventy or eighty pieces in an instant by Li Yao with a bloody wind slashing knife.

In less than ten minutes, the inside of the mine was clean, and there was no more half of the fierce ice store.

"In this ancient battlefield, there should be no ancient powerhouses, and what is devoured by the ice is the fighting spirit of ordinary soldiers, so the fierce ice spirit formed is not very strong."

"If it is the battle intent of the ancient powerhouse and the combination of the huge ice evil in the depths of the earth to produce a fierce ice spirit, it is an extremely terrifying existence!"

Captain Hong Dong breathed a sigh of relief, and after everyone simply cleaned up the battlefield, they continued to move forward.

Beyond the wreckage of the minecart is the main working surface of the underground mine.

There were several pieces of crystal armor scattered in the corner, but after Li Yao checked it, he found that all the crystal armor had no weapons on it, and the structure was different from the battle armor.

Li Yao secretly smacked his tongue:

"I have long heard that in the era of the Star Sea Empire, the cultivation world has developed the crystal armor technology to the peak of Cheng Dù, and the crystal armor has also been popularized in the entire society, not only cultivators, but even ordinary people have their own crystal armor."

"When I saw it today, sure enough, even the crystal armor used for mining was used. In this way, ordinary people can go to work in places with harsh environments, which greatly enhances the efficiency of resource collection and utilization of the entire civilization. ”

"No wonder the Star Sea Empire can dominate the universe for thousands of years and become the most powerful empire in human history!"

"We still have a long way to go in the Star Federation!"

Just thinking about it, Ding Ling's excited cheers came from the communication channel:

"Found it!"

She's near a bunch of cyclops. Found a Nine Hole Stone.

The Nine Trick Stone is a thumb-sized ore, and each Nine Hole Stone has eight to nine small holes, which are arranged very strangely, like a small human face with three or four eyes, and a nose, mouth, and ears.

When some of the Nine Aperture Stones are collected, there will be a pale gray liquid flowing from the "Nine Apertures", which will solidify after five seconds of seeing the air, which is the "Melting Spirit Crystal".

"It's good, I found a Nine Aperture Stone so quickly. It seems that we are lucky to go out this time, so let's rest for ten minutes before we start collecting! ”

With a wave of his hand, Li Yao took out six circular prohibitions from the Qiankun Ring and found a flat ground in the corner of the mine.

As soon as the ban was opened, the air inside and outside was separated.

Then he took out a purification charm to purify the air inside the forbidden area into clean air that could breathe, and all the team members took turns to take off the crystal armor. I simply took two bottles of high-energy nutrients.

Although the Tsukiki monks can go days and nights without food or drink, they can face fierce battles at any time. It's better to try to keep your body's psionic energy reserves.

After resting, the Bronze Clans searched all the work surfaces, cleared a total of four waves of ferocious ice, and set up six defensive talismans, and then began to collect.

Everyone was divided into two teams, "Swallow" Yan Yangtian and "Bullet Shell" Leng Ziming formed a two-person reconnaissance group. Back on the surface, take the mine as the center and launch a spiral search in all directions.

On the one hand, it is necessary to develop the map, and on the other hand, it is also to ensure the safety of the mines.

The other four began to look for the Nine Aperture Stones and Melting Spirit Crystals near the Red-veined Cyclops Mushroom.

Although it is the first time to collect heavenly treasures in the secret star. However, since the Hundred Refining Sect 40,000 years ago was a refining sect, of course, there were many secrets that were not passed down for the collection and use of heavenly materials and earth treasures, and Li Yao devoured Ou Yezi's memory fragments, and also mastered many secret methods.

So, except for being a little clumsy at the beginning, Li Yao's collection speed soon improved by leaps and bounds, and by the next morning, he surpassed the captain Hong Tong.

By the second night, he had already filled up a Qiankun Ring and had to use his personal Qiankun Ring, and the amount of collection greatly exceeded the sum of the captain Hong Tong and the "dumb" Ba Weiqi.

Ba Weiqi didn't believe it at first, and wondered if Li Yao's collection action was not very neat, so he also collected a large amount of ore attached to the Nine Tricks Stone.

But in the evening, when everyone gathered in the forbidden area to sort out, they found that Li Yao not only collected the largest quantity, but also had the highest purity, and there was not even the slightest impurity on each Nine Aperture Stone, and more than ninety percent of them were rich in Melting Spirit Crystals.

"Vulture, why are your kid's eyes so vicious, all the best Nine Trick Stones have been collected by you!"

"Dumb" Ba Weiqi scratched his head in confusion, and he really couldn't figure it out.

"Probably because I was born with heaven and earth."

Li Yao was also very excited, this kind of skill of collecting heavenly and earthly treasures, he only had a theoretical understanding in the past, but this time he used the exploration trip of the Xuanbing Star to hone it, and he made a lot of progress.

The Nine Aperture Stone and the Melting Spirit Crystal are not the rarest treasures of heaven and earth.

If you encounter a truly unique treasure in the future, this kind of collection technique will be very useful.

Just when everyone was talking and laughing, Leng Ziming, the "bullet shell", returned to the mine with a chill, and the news he brought made the smiles on everyone's faces instantly froze.

The reconnaissance team found traces of the demon clan's activities 324 kilometers away.

I was watching the parade in the morning, and I was so excited to watch it, so I didn't update the first chapter until now, so I'm really sorry guys! (To be continued......)
