Several other secret research bases such as 5021 were also ordered to send their strongest forces to the Zhushan base.

It has to be said that although the demon disasters in the Eastern Kingdom have not yet become a climate, they naturally do not have a powerful extraordinary organization like the Demon Hunter Guild.

But the official has not been in vain for many years. He has already used various methods to secretly accumulate a large wave of power.

These secret powers are hidden very deeply, but this time, with the words from Qingyun, everything was alarmed as if they were stabbed in a hornet's nest.

5021, which studies extraordinary serum, 5019, which studies individual combat equipment suitable for underground combat, and future creatures that secretly conduct biological research on underground creatures. As well as experts from the Military Bureau and the Special Intelligence Bureau, they all rushed to the Zhushan base.

So when Qingyun arrived at the Zhushan base, he was quite shocked to see this scene: "What are you going to do? Are you going to fight a world war?"

Mr. Luo, who was sent to take charge of this operation, smiled and said, "Master, we will take advantage of your east wind to take the opportunity to conduct a comprehensive offensive and survey of underground creatures!"

The behavior of modern countries is not as willful as that of ancient kings.

In fact, this operation has developed to this point and has become the official concentrating all its forces to conduct a large-scale suppression and cleanup survey on the underground of Zhushan!

Although the underground lizard monster at Zhushan base is not as fierce as Beimi.

But this is a hidden danger after all!

Take this opportunity to kill again and again. Even if it is not good, we must find out the underground situation clearly.

However, after hearing this, Qingyun looked helpless. I went to the underground to get some dark silver back. What's wrong with so many of you following me?

It’s not that Wei Qingyun looks down on these people, but that he really goes deep into the ground, all of them are burdens!

"Depending on the ground, there will be poisonous fog in many places where fluorescent grass grows.

The fog is composed of countless tiny spores that cannot be seen by the naked eye. Whether it is breathing in or falling into the corners of the eyes and ears, it will make people crazy. In severe cases, it will even reproduce and grow in the body...

How do you get in?" asked Qing Qingyun.

"We have gas masks and protective clothing..."

Before he finished speaking, he was laughed by Qingyun: "The underground environment is complicated and there are many stones. You may encounter a lizard monster. What if your protective suit is broken?"

Everyone couldn't speak immediately. Yes, according to Beimi's experience, it may be dozens of kilometers deep into the ground, and various dangers may be encountered.

No matter what protective clothing is, it is likely to be damaged...

"But, Master. Then how can you go?"

Qingyun laughed and said, "I can breathe in the fetus!"

"But light can cause fetal breathing..."

"Tell you the truth, you are a burden when you are with me. In fact, after entering fetal breath, all my breath will be hidden.

In addition, if I act alone, I will not alarm those underground lizard monsters at all. I can easily sneak into the underground to investigate!

You don’t need to say more. When your superiors ask, they say it’s my decision!”

As he said that, without waiting for them to refute, the whole person turned into his internal breathing.

At the same time, the entire presence of Qingyun disappeared.

Even though they could see clearly that Qingyun was standing in front of them, they could not feel the existence of this person.

Those who followed Qingyun deep into the ground were all masters with sharp senses. At this time, they could no longer hear any breathing and heartbeat from Qingyun, and even their breath disappeared completely.

This is really contradictory, and it makes people feel uncomfortable for a moment and want to vomit blood!

However, before they could say anything, Qingyun quickly disappeared into the depths of the dark cave.

Many of the masters sent here come from the outside of the Great Bear Temple and know a little bit.

Seeing this scene, I was shocked.

"I have always heard that this master is a god and I was a little suspicious.

Now it seems that if we really follow in, it might be difficult to take this real person seriously…”

Generally speaking, if you practice martial arts innately, you can enter the realm of fetal breathing and cultivate internal energy.

But at that time, the fetal breath could not move at all, and it was more like a tortoise breath.

It is beyond imagination to move into fetal breath like Qingyun.

It also goes beyond the scope of martial arts!

Only the legendary inner immortal can do it.

But what are the abilities of those inner immortals? Only some legends are left.

At least no one can explain it clearly now!

At this time, Qingyun quickly left hundreds of meters away and entered one of the forks.

At this time, the cave was still open, and the speed of Qingyun was naturally very fast, so it was easy to walk.

However, as we go deeper, the underground tunnel will become sometimes wide and sometimes narrow. When it is wide, it can form an underground space as big as a basketball court, but in a narrow place, only one person can walk sideways.

If you don’t go deep into the ground, you would never have imagined that there would be such a complex tunnel system underground.

Of course, without thinking about it, you can also know that this is by no means natural!

The fluorescent grass emits a faint green light, although extremely weak.

However, in the eyes of a master like Qingyun who has reached the point of whiteness in the virtual room, as long as there is a little light, you can clearly see things.

The Qingyun didn't even bring a light source, and moved forward with the help of the light of the fluorescent grass.

Among the ancestors of the Thunder Mountain, not no one has stepped underground.

According to the statement left by some ancestors who have been deeply underground in the past dynasties, it is to not enter the realm of scattered immortals, entering this underground is seeking death!

"It's a pity that I didn't have some magical equipment that the ancestors who entered the underground back then..."

Back then, not only did the scattered immortal masters from the Thatched House Sect step into the ground, but also other immortal sects.

Even if you enter more, you will accumulate rich experience.

Some clothes and facial towels are needed for woven silk to block the poisonous spores. There are also various magic weapons, flying swords, and so on that are used underground...

For example, even if you are a scattered immortal, you cannot breathe inwardly, and you will eventually have to breathe.

There is also going deep into the ground. If it is not good, it will take dozens of days. Do you always have to eat and sleep?

All of these must be prepared.

However, most of these things are not available, and many of them have been lost... magic weapons have long been useless!

But don’t forget that today is a modern society, and there are many things to replace.

For example, magic tools...

Qingyun has no attacking magic weapons, such as flying swords.

But he has a gun in his hand!

However, where fluorescent grass grows too much, large areas of green mist will gather, suspended in the cave, which is very dangerous.
Chapter completed!
