In fact, there are many people who are uneasy with Mu Youchen and Hua Taiqing, but now is the time when morale is strong, and it is obviously not suitable to say anything discouraged.

However, the strengthening of manpower patrol vigilance has been done without leakage.

Everyone knows that they are now in the territory of humans and demons, and any negligence will wipe them out.

Darkness is the main tone of the underworld, and anyone who stays in this darkness for a long time will be afraid, right?

The race of humans and demons has survived in the dark for countless years, but now they don't know why they want to explore the outside world.

"The scale armor of the human demon is black, and it is simply a natural night suit. Our visual distance is limited, and if we sneak in front of our camp and don't reach our vision, we won't be able to detect it. And the reason for the terrain ......"

Mu Youchen pointed to the terrain in front of him and said, the terrain of the underground world cannot be described by the terrain vocabulary of the surface world at all.

Plain? Mountain area? Basin?

Sorry, these terrains are almost every kilometer, and everyone goes through them.

There are enough thousands of human demons to hide in these strange terrains, so how to see if there are human demons sneaking up on the camp of the Snow Immortal Sect is a crucial issue.

"I think it's better to let the disciples use snow oil to light a fire two hundred meters away from us, so that we don't have to worry about the sneak attack of people and demons."

Hua Taiqing said with a smile, Mu Youchen's worry was undoubtedly correct. In fact, after hearing Mu Youchen's reminder, Hua Taiqing also realized the seriousness of the matter.

"Okay, if it's okay, let's set it up quickly."

Mu Youchen frowned, her premonition was very bad.

Hua Taiqing saw Mu Youchen's appearance, and did not dare to slack off, and hurriedly went to the deacon elder, although his current identity is not what it used to be, but such an order still needs the order of the person above.

After Mu Youchen waited for Hua Taiqing to leave, he looked at the patrol team that had just left, raised his eyebrows slightly, and then jumped out of the stone wall while taking advantage of the darkness, and then walked towards the endless darkness.

After a whole day of watching coldly, Mu Youchen felt that his body was going to rust. She chose to go it alone because she always did.

And with the protection of the Ice and Fire Demon Ding, Mu Youchen will not be in any danger.

Of course, the trip wasn't about looking for thrills.

The terrain of the underground world is complex, and there are already mountain peaks in front of the plains at your feet, and the next thing you can do after turning over the peaks may be basins.

In such a terrain, even if the Spirit King and the Spirit Emperor powerhouse were flying in the air and repeatedly reconnoitred, it was impossible to explore more information, so Mu Youchen decided to act alone and explore some useful things.

And the first thing to do is to clear Huatai......

Walking in the dark, Mu Youchen didn't have any worries. In the dark, Mu Youchen is even more like a fish in water.

Moreover, Mu Youchen's power is excellent, and he can see things a hundred meters away, even a little movement.

The camp behind him was still jubilant, and Mu Youchen had gradually walked into the silence of the darkness.

Forward, forward......

After traveling about two kilometers, Mu Youchen could no longer see the situation of the Snow Immortal Sect's camp at all, and he could only see a little fire when he stood on a slightly higher hillside.

Through the firelight, Mu Youchen determined that the camp of the Snow Immortal Sect was still safe and sound, and along the way, Mu Youchen did not find any suspicious circumstances.

However, Mu Youchen felt as if something was waiting for her to decipher.

And......

The temperature is gradually rising, although the change is not very big, but Mu Youchen can clearly feel it.

The temperature of the air, the temperature of the earth's surface, and especially the temperature of the earth's surface!

"It could be underground magma, it's about a kilometer away......

The voice of the Ice and Fire Demon Ding came, obviously realizing that something was wrong. The core composition of the Ice and Fire Demon Ding is flame, so it is very sensitive to things in the form of flames.

Underground Magma ......

Mu Youchen's expression began to become solemn, according to Hua Taiqing, the elder of the Snow Immortal Sect who had been in the underground world for two years left a record in the book.

Humans and demons, like humans, also need to maintain their own body temperature.

And in the underworld, where there is molten slurry, it is often a place where a large number of people and demons gather!

And now in this place, there are a large number of people and demons gathered.

And the Spirit King of the aerial reconnaissance actually said that there were no traces of people and demons around, which shows the negligence of intelligence!

If this were in a human country, such a spy would definitely be dragged out of the camp and beheaded directly.

You must know that any negligence in reconnaissance will cause terrible consequences, and the most tragic thing is undoubtedly the total annihilation of the army.

And thinking about it again on this day, the humans and demons encountered by Mu Youchen and others turned out to be from one direction. And the largest gathering place of humans and demons is also in the same direction, as if it is resisting the advance of the Snow Underworld Sect, and it is also telling the people of the Snow Underworld Sect that the front is an important place for humans and demons.

In this way, the Snow Immortal Sect will move forward bravely and ignore the surrounding environment.

In this way, in fact, the Snow Underworld Sect has been in the design of humans and demons from the very beginning!

Thinking of this, Rao is Mu Youchen was bold and also broke out in a cold sweat. Unexpectedly, they have long fallen into the trap of the enemy.

Thinking of this, Mu Youchen even had the idea of exploring thoroughly. With a movement of her feet, she moved forward quickly like a ghost, and she had already guessed the plan of these demons, so she was not worried that she would encounter demons on the road.

By the time he traveled another kilometer, Mu Youchen had already seen the red light that illuminated the surrounding space.

This should be a basin surrounded by mountains, and some human and demonic actions can be vaguely seen on the mountain, but the distance is a little far, Mu Youchen can't see it really, and he can't see how many human demons there are.

Therefore, Mu Youchen gradually approached with the help of the complex terrain around him.

Although the complexity of this terrain is convenient for people and demons to hide, it is a good place for Mu Youchen to hide, with Mu Youchen's concealment skills, even if she is discovered by people and demons, she can hide and not be caught.

Of course, be careful.

When Mu Youchen slowly climbed up the mountain, it turned out to be half an hour, and there were hundreds of people and demons on the way.

But when Mu Youchen stood on the top of the peak and saw it down the mountain, he realized that the hundreds of human demons he saw were just a drop in the bucket!

A huge basin with magma tumbling and flowing at the bottom of the basin.

And on the slopes, countless human demons are receiving the warmth of magma.

At least 10,000 human demons!

This is only a preliminary estimate, and how many human demons are still in that tortuous basin, Mu Youchen can't explore at all.

But just the number of people and demons in front of her was enough for Mu Youchen to be shocked, fortunately she sensed that something was wrong, and fortunately she came to investigate.

Otherwise, once the Snow Underworld Sect continues to move forward, these demons will block the back road of the Snow Underworld Sect, and the Snow Underworld Sect will really be wiped out!
