Negative energy will stimulate the most primitive fear of living beings, causing irritability, restlessness, doubts, etc., if the energy intensity is too high, it will even penetrate ** and even the spirit, and eventually pollute the human body, resulting in demonization reactions.

Everyone stayed for less than 20 minutes, and all of them obviously felt unwell, such as increased heart rate, upset, etc.,

Mu Ying'er was the most affected.

Although carrying the Holy Spring Elixir with you has a strong purifying effect, in the current environment, the dark energy will continue to be absorbed by the human body, even if it is temporarily purified, it will soon accumulate again. The power buried deep in the soul, the will that sleeps in the endless sea of consciousness, is resonating with the energy of the outside world, and it seems to wake up at any time.

"There's light!"

The long silence was broken, everyone felt a shock to their spirits, and in front of the dungeon corridor, there was indeed an exit, and the light shone in, so that people could see clearly, and immediately speed up and walk out.

The moment he came out, the light made people squint slightly, he stood on a platform protruding from the cliff face as high as sixty or seventy zhang, more than twenty people were standing on the platform, and when he looked at it from a distance, he saw a withered forest.

That's right.

In a place a few hundred meters deep, a large area of forest appeared, and when I raised my head and looked at the sky, the rock wall above my head was flattened and polished very brightly, according to some mystery and law, thousands of light spars were inlaid with it, and in the center was a huge magic circle. Although 20,000 years have passed, the giant light system magic circle is still operating, and the center of the six-pointed star array releases a strong light, like a miserable white sun, and the entire underground space is illuminated.

Artificial sun, running for 10,000 years!

Miraculous technology!

Qin Yue helped Ying'er to the side to rest, she held her glasses, looked at the strange scene in front of her, and showed a confused expression between her eyebrows: "This place looks, why does it feel a little weird and gloomy?"

It's not just Qin Yue.

In fact, everyone has already felt the anomaly, from the perspective of the huge underground space, covering a large area of dead tree forests, and leaving traces of riverbeds on the dry ground, which shows that the underground space was once a closed-loop independent ecosystem tens of thousands of years ago. At that time, the underground forest must have been a scene of bleak life, but now for some unknown reason, the entire ecosystem has collapsed.

The forest of dead wood is full of strange gloom, and at the same time it is filled with a layer of gray mist, which is extremely quiet and colorless, and everyone feels a feeling in their hearts when they look down on the earth. It's a dead world, like an old gray painting on display, with no life, no change.

The most troublesome thing is.

The entire space is filled with negative energy, and although it is not as rich as in the dungeon, it can still cause danger.

Gu Boyun looked at both sides, steep cliffs, every thousand kilometers apart, there were exactly the same platforms and caves, in other words, the space passage was not separate. It is still possible for others to come to the underground space through other passages.

"Hurry up, let's go!"

The crowd managed to leave the cliff and enter the dark and dead forest, where the whole forest, or the whole world, was shrouded in a gray mist. Not only does it obstruct vision and hearing, but the fog also contains an aura of death and darkness, making it feel cold and terrifying.

Mu Yun said as he walked: "The energy intensity in these fogs is very high, everyone must lift their spirits, otherwise they may hallucinate, or even be controlled by them." This place must be the core area of the Sky Covering Beast Research Institute, and if I guess correctly, the place where the biosynthesis technology and Sky Covering Beast eggs are stored is in the middle of the woods. ”

Gu Boyun nodded and said, "It's best to take the things away and evacuate before the others arrive." ”

If you can fight, you won't fight.

This team no longer has any advantage in terms of numbers, and if it encounters the main force of the Brute Martial Domain, or the strong team of the Red Moon Sect, the chances of winning will probably be very slim. There is a Tianwu Marquis in the Barbarian Martial Domain, and there is a blood clan powerhouse in the Red Moon Church, neither of them is easy to mess with, and if you fight against it in the wind, you may not be able to win.

Half an hour.

Mu Yun led the team into the depths of the dead wood forest, there were gray and white trees on all sides, these trees died I don't know what species, they have been dead for at least tens of thousands of years, and they still maintain their basic form intact, but the trunk and branches are completely shrunk and hardened, thus turning into complete stones, like fossils buried for tens of thousands of years.

As Yao Tianxiang looked around, he suddenly seemed to have found something, and immediately said excitedly: "Have you seen it?

There was a big tree four or five feet thick, and there were four or five black lingzhi on the surface.

Gu Boyun is very knowledgeable, and he basically recognized it at a glance: "Dark blood Ganoderma lucidum, a very rare material, it is said that the longer the age, the more toxic it is, and there is basically no medicine to solve it." These strains are probably thousands of years old, and even if a dragon eats them by mistake, there is a danger of being poisoned. ”

Yao Tianxiang loves poisons, and he will not fail to know the dark blood lingzhi, and immediately go to pick the highly poisonous elixir.

The dark blood reishi looks very ugly on the surface, the texture is very hard, like iron and stone, and during the cutting process, it must be cut from the roots, otherwise there will be toxins leaking out, thus posing a danger to the collector. Yao Tianxiang pulled out a sharp short sword from her boots, carefully dug out a few strains of dark blood reishi, and then put them into the prepared bag.

Others slowed down.

It doesn't seem to be uncommon for dark-blooded reishi to be found in dead forests, and there are several dead trees nearby that grow this kind of thing. A few of the alchemists couldn't hold back and wanted to run to collect one or two. Even if you don't use this thing, you can still sell it for thousands of gold coins. A thousands of years old dark blood reishi is very rare and rare, and some large mercenary groups are ready to hunt fourth-level or even fifth-level demonic beasts, this thing is very useful.

"Wraith Grass!"

"Shade Vine!"

"There are so many treasures here!"

Several warlocks found several rare materials in succession, all of them showing excited and greedy expressions.

Mu Yun and Qin Yue frowned, now is not the time to dig treasures, Mu Ying'er stays for one more minute, the danger will be one step closer, Mu Yun immediately said: "Don't waste any more time, these are simply not worth mentioning compared to the things in the laboratory, we ......"

The words are not finished yet.

Feng Zhongmian suddenly found that there was a flashing shadow in the gray mist, and immediately pulled out the wind and snow sword and said, "Something has appeared!"

Mu Yun was stunned.

It's the kung fu of a stunned god.

A translucent silhouette burst out of the gray mist, and a sharp blade stabbed at it. Feng Zhongmian raised his hand and a sword qi hit the body of that thing, and the original translucent body outline collapsed in an instant.

Meng Hu pulled out the bow but had no goal, frowned and asked, "What kind of monster is this?" Even if it is killed, at least leave a corpse, how can it be like evaporating?"

Gu Boyun had studied demons for more than ten years, and immediately thought of a demon life, and hurriedly shouted: "It's the fog, this is an elemental lifeform, it is difficult to be killed by ordinary attacks, and the warlock opens the defense!"

"Ahh

A warlock was pierced through his chest by a transparent blade, and blood splattered on the spot. Behind him, there stood a translucent silhouette, this creature was composed of gray mist, completely unfixed form, but in his right hand held a solidified sharp blade, piercing the warlock's chest at the same time, the fog dispersed completely, turning into a large amount of fine gray smoke, burrowing into the warlock's seven holes.

This warlock, who was supposed to be killed, suddenly his eyes bloomed with scarlet light, and his hands were raised, and a few fireballs were attacking the others.

Gu Boyun shouted, "He was eroded by the fog!"

Meng Hu shot an arrow directly through the warlock's abdomen and pinned him to a tree, the warlock must have died. The mist was enough to kill him with a single blow just now, and Meng Hu's arrow contained powerful true qi, which was enough to shatter the internal organs and bones in the warlock's body, but after being nailed to the tree, he still cast the spell as usual, and several ground thorns rose from the ground, instantly appearing in the center of everyone.

Gu Boyun passed with a spell.

Rumble!

Flames rose into the sky.

The warlock eroded by the mist, as well as the big tree behind it, was completely blown into pieces, only to see that inside the warlock's corpse, a humanoid silhouette immediately appeared, and the ancient thin cloud staff swiped lightly, and the surrounding flames were all covered, and the whole body of the fog turned into a fireball, making a hissing sound, and was finally evaporated.

Lots of fog!

When the first fog appeared, the thick fog in the vicinity boiled and rolled, and the translucent outline was almost everywhere.

"We are surrounded!"

Feng Zhongmian cut off the two fog demons with a sword, but after the fog shatter was cut off, although he suffered a heavy blow, he did not die, and his body quickly recondensed. The fog is growing in number, almost all over the nearby forests, and these evil life forms are so powerful that only light and fire spells can kill them or dispel them with their aura.

Mu Yun immediately turned on the light shield technique. The mist attack on the defense condensed by light energy, and half of his hands evaporated in an instant, and he stepped back with a miserable scream.

"Blessing of Light!"

Mu Yun's fingers swept over the blade of the sword, and the blade was shrouded by the light element and turned into a light blade, which suddenly stabbed into the body of the fog, and the light element evaporated the body in an instant, and the fog shattered with a scream. Mu Yun did not directly use attack spells, but condensed light energy on the weapon, and used melee combat to eliminate the fog evil, so that he could save more mana.

"Old Meng, madman, give me the weapon!"

Mu Yun took out the talisman and pasted it on the weapon, blessing the light energy for the two, Mu Yun prepared the talisman and the spell was limited, and the others could not do anything.

Everyone gathered in a circle, with the warrior defending on the perimeter and the warlock in charge of counterattacking. At this time, the surrounding mist rolled like boiling water, and hundreds of fog shatters appeared, without a fixed form, some became human-like, some became beast-like, and some became four-like, atomized bodies, only partially solidified when attacking.

"Woo woo——!"

The fog is not very intelligent, it attacks by instinct, hundreds of fog demons, on the ground, in the air, above the head, their bodies are very light, so they can float, and the direction of attack is all-round, which will greatly increase the difficulty of defense.

As soon as Gu Boyun's staff was inserted, the scorching aura was released, and the raging flames spread out, and the ring of fire instantly surrounded everyone.

Level 3 Spell Fire Wall Enchantment!

This is a very strong level 3 spell, and more than a dozen mist shatters collided with a burning flame barrier, and they were on fire on the spot, and their screams dissipated. Seven or eight misty fists bypassed the barrier and attacked directly from overhead.

"Destroy them!"

Another Archsorcerer's staff was raised, and a red glow erupted from the tip of the staff, and ferocious flames erupted, engulfing several mist demons in flames.

The number of fogs is not decreasing, and it is constantly increasing. Although Gu Boyun's mana is not weak, it can't maintain the fire wall enchantment for a long time, and the number of fog demons doesn't know how much, I'm afraid it will be very difficult to win.

Qin Yue felt a trace of mental fluctuation, and immediately said, "The fog is communicating!"

The Fog Sha has a very low IQ, but it doesn't mean that he is a fool, and the Fog Sha can't break through Gu Boyun's barrier, and immediately wants to find other countermeasures. It was a collection of tens and hundreds, all of which gathered together, and when the body came into contact, it was like glue that could not be separated, and the fog began to merge.

Dozens, even hundreds, of them all gathered together.

In the end, it converged into a giant more than three feet high,

Damn it!

These things are in one!rg
