It took a while for the howling inside the doorway to subside.

A chilly aura emanates from within, making people feel like they are facing an iceberg.

The withered tree monk said in a deep voice: "Amitabha-"

The sound of the Buddha horn is like the sunshine of spring, dispelling the cold air, making people feel a breeze on their faces, like a spring breeze, and breathe a sigh of relief.

The laughing monk waved his hand and said, "Let's go, and see what's inside." ”

Now there are laughing monks and Cheng on the side of the guardian organization, and there are several guardians with good strength, who are the strongest.

If the other forces do not unite, they cannot compete with them.

The laughing monk was the first to step into the gray doorway, and everyone else rushed in.

Wu Tian cheekily followed Cheng Yuan's side, and as soon as he entered the doorway, it was as if he had entered a misty place, and there was a gray aura around him, cold, as if it was the air coming out of the freezer.

"There is a lot of yin qi, but it is useful for cultivation. The laughing monk said with a smile.

As soon as Wu Tian heard this, he hurriedly spread out the Buddha palm in his right hand, and soon a line of hints appeared in his mind: collect the Yin Qi specimen of the underground palace, and the points are +100, +100......

Looking at the numbers that kept emerging, Wu Tian was pleasantly surprised, it seems that in addition to the reward points for completing the task, the specimens collected here also have a lot of points.

The laughing monk glanced at Wu Tian and asked with a smile: "How is it, I'm not wrong, but be careful, you can't chew too much!"

He saw Wu Tian stretch out his right hand, and the yin qi next to him quickly converged into the palm of his hand, and he thought that he was refining the yin qi of the underground palace in this way.

Wu Tian smiled and said, "Thank you for reminding me, I will be careful and will not mess around." ”

Soon, 50 points of specimens were collected, and 5,000 points were obtained, and then collected can only be stored as samples in the system space, and points cannot be obtained.

Anyway, the system space is still sufficient, so Wu Tian followed Cheng Cheng and stored it while absorbing it.

Specimens can be extracted by collecting them and storing them in the system space.

Wu Tian thought of a very good operation, collect as much underground palace yin qi as possible along the way, and when the time comes, fight with people, extract and smash it over, what will be the effect?

This made Wu Tian look forward to it very much.

"Hey, hey, hey...... Hahaha......"

Bursts of sneering, like night owls, came from all directions, and the gray mist around them rolled in bursts, as if the waves were rolling.

The feeling of the crowd became colder and colder, and the temperature of the air dropped sharply.

"Ahh

"What's wrong with you, wake up. His companion screamed and tried to lift him up, but as soon as he touched him, it was like a block of ice, and he quickly retracted his arm in fright.

Then, the companion's expression suddenly froze, as if his soul had been taken away in an instant.

The gray mist around them quickly gathered and enveloped the two men together.

"Ahh

The terrible screams came from the fog, and it gave goosebumps all over the body.

"Amitabha—"

A clear Buddha horn sounded, but the withered tree monk couldn't see it, and shot directly, only to see him stretch out his hand, and a silver light flashed, which immediately dispersed the mist that wrapped the two guys.

"Bah-"

The fog cleared, and two white bones fell on the ground, which were the two monks just now.

In just a minute or two, they were sucked out of all their flesh and blood, and they died in the dungeon.

The withered tree monk pronounced a Buddha horn, with a sad face, but unfortunately the two were dead, and he couldn't bring them back to life.

The two monks who turned into a pile of white bones had a strength of about three to four grades, which was not bad, but they died so quickly, which suddenly made people feel the danger of this underground palace.

And this has just entered the underground palace, if you go deeper, what will happen?

The weaker monks and monsters turned heavy on their faces.

Wu Tian looked at the monster map, and saw that it was densely packed with white dots, constantly moving, like a wave.

These are the primary yin souls of the underground palace, they are located on the periphery of the underground palace, and they are transformed by the souls of the soldiers, palace maids, eunuchs and other soldiers who accompanied the burial of the king of Shu when he was buried.

If it's just one or two Yin Souls, it's not afraid, but with so many Yin Souls, gathered together, the strength is completely different.

Once they seize the opportunity to get closer, it is easy to be captivated and then unknowingly suck the flesh dry.

Of course, such powerful existences as Cheng Deficiency, Laughing Monk, Dry Tree Monk, and Ox King are vigorous in qi and blood, like the sun at noon, so that they don't dare to approach at all, and they mainly choose those weaker monks and monsters to attack.

"Master, I want you and me to join forces to sweep away these imps. The laughing monk suggested to the withered tree monk.

Although these yin spirits posed no threat to them, they were floating around, forming a thick mist-like yin qi that affected their perception.

The withered tree monk nodded, his hands folded, and the palms like white jade glowed with a layer of white light.

With him as the center, the temperature around him suddenly increased by several degrees, as if the air conditioner was suddenly turned on.

And the laughing monk clenched his fists, and slammed out a golden light, and the fists turned into golden light, passing through the mist, like a sharp sword, where he said, there were bursts of terrible roars in the mist, like a monster grinding its teeth.

At the same time as the two of them shot, Cheng Deficiency, Niu Wang and others also followed, their strength was weaker, and the scope of influence was smaller.

When the others saw this, they also followed.

Soon, the surrounding fog seemed to be greatly threatened, and knowing that it could not fight these people, it swept into a ball, like a cluster of bees, spun in mid-air, and flew forward quickly.

The fog dissipated, and the light around it did not brighten, it was a corridor about three feet wide, and there was an ever-bright lamp inlaid on the top of the head, and I don't know what material it was, but it was never extinguished.

The laughing monk took the lead and walked forward along the road.

The further you go, the wider the road becomes, reaching six or seven zhang.

In front, the corridor is divided into three.

The three Yongdao roads were exactly the same, and everyone stopped and carefully observed the three Yongdao, but they didn't find any difference.

The inside of the corridor was pitch black, and nothing could be seen, not like there were ever-bright lights before.

"It's so depressing here. Someone sighed.

It's as if the air around is being pumped clean.

"Da, da, da—"

The sound of horses' hooves came from the three corridors, as if thousands of horses were rushing towards them.

Everyone suddenly became nervous and took out their weapons one after another.

"Assert ......"

There was a cold laugh, and from the dark corridor, rushed out a group of bone horse bone soldiers, all of them holding long hair, their spears rusty, and the rust spilled into the ground as the bone horses ran.

The three teams of white bones rushed over and surrounded everyone together, and the eyes of the bone horses and bone soldiers were staring at everyone as if they were conscious.

A sinister aura spread rapidly.

"Giggle-" Someone chattered his teeth with nervousness.
