The base that can purify the air by itself and produce oxygen is a big place, otherwise, the equipment will not keep up.

Therefore, Agni and Hirono thought of a possibility at the same time, that is-research institute!

Hidden research institutes set up in dangerous areas, such research institutes have also been set up in safe areas before.

It is like a very small safe area, with only one building area as big.

The initial safety zone also came from this way, starting from the small piece at the beginning and then slowly expanding.

But outside, there is no such thing as a safe zone.

Because the area is too small, there may be attacks from snakes, insects, rats and ants under the land, and attacks from beasts on the land.

Because the country has occupied the surrounding area, although mercenaries can enter the danger zone through detection, they do not have the right to build research institutes in the fixed danger zone.

In the Dangerous Zone Construction Research Institute, this is a project that most people cannot do, unless this person successfully reaches an agreement with the national government through his own powerful means and obtains permission.

Obviously, the mercenaries did not fulfill this condition.

Therefore, in each area, I have never heard of where there is an external research institute.

People nowadays have obtained a large amount of research resources through their own various means. The crystals and various plant materials collected by the army will be successfully delivered to the people in the safe zone.

Because of the strength of the army, the safe zone can obtain various favorable conditions.

However, because mercenaries collect all kinds of people, there is no consistent training and regular arrangements. Therefore, for mercenaries, they have to accomplish one thing, complete a difficult task, and what is needed It's not a normal time.

The rule of survival of the fittest in the world is not a fake.

But if they really set up a research institute in the danger zone and have been studying it for a long time, then it would be considered a skill.

Research institutes need resources and protection. Their research institutes are definitely not in a fixed danger zone, so they are somewhere close to an infinite field.

Such a place is more dangerous than a fixed danger zone, so they need to maintain a large number of personnel.

In areas where a large number of people enter, the various animals and plants in the forest are not so easy to provoke, so their actions should be quite difficult.

Both Agni and Hirono automatically performed a lot of brain supplements in their own minds, but Streamer had no idea about these.

After all, since his birth, he has not seen anything dangerous. The danger zone is very free for him. On the contrary, only human beings make him feel uncomfortable.

He has no particular affection for human beings, except for his father, he doesn't like anyone else.

Originally, he didn't have any big expectations for the safe zone, but when he met Zhuo Yuan, he had an inexplicable affection for him.

I think he is very close and kind.

Although the two people hadn't said anything, at least Zhuo Yuan seemed to be very honest, sincere to him, and didn't hide any bad thoughts.

"Little guy, you live in the forest. After you come back, the mercenaries respect you again and say they protect you. Then why do you have to leave? Just because you don't want to be a wife for the old man?"

"I said, I'm not interested in that person, I just want to see what the safe zone is like."

"I understand this, but when you are on the mercenary side, you can also see the safe area, and they can give you some protection."

"I want to see for myself, and I don't like people following."

Streaming Firefly didn't hide his temper, his unhappiness was all on his face.

Speaking of mercenaries, he also thought of those bad things.

Originally he hated them, so he couldn't stand their hypocrisy even more.

It is to protect him, but in fact I want to monitor him. Every word he said is against his will. Only the sentence that he is rarer than a woman is true.

In contrast, even if Hiyono had selfish intentions and intentions towards him, at least he admitted later that those people would not dare to admit their true thoughts to him.

They will be afraid of themselves, but definitely not really respect.

"If you want to know more, when you go to the danger zone, I will tell you what kind of secrets I have."

Liu Guangying simply threw a word out, and he understood some of Agni's character. Agni is not the kind of person who likes to hide his mind.

I heard that he never liked to think about the consequences of what he wanted to do. When he thought about it, he would definitely do it.

This kind of personality, to the streamer, he quite likes it.

"it is good!"

Sure enough, Li Huo readily agreed to him, only Hei Yunuo, who was more thoughtful, couldn't help but smile.

His hunch was always accurate, and he always felt that something unexpected would happen when he went to Area A this time, and his eyelids always felt a little sudden.

The two people in front of them kept fresh about the battle, and they didn't think about other things.

The work of defense can only be left to him.

First of all, he notified the people in the border area in advance to vacate the field and they would pass directly.

The major general and the lieutenant general do not need to be checked. They have the right to go straight. He Yuno just showed his face and they just let it go.

In this regard, Liu Guangying felt fresh.

Because when he entered the safe area last time, those people said that they were very nervous, and they were carefully investigating them, and they had been checked one by one before they could enter the area.

Some people even cursed, saying that the Saint Hua Army garrisoned at the border is really annoying.

Others whispered bad things about him, complaining that if they hadn't had to take more forest routes, they wouldn't need to be checked one by one.

"Novel? Don’t think it’s novel. If you always walk with me, you don’t need to check. My military position, that is, my status is still there. Especially in my own area, my rights are great. At the same time, this is also one of my abilities. Believe that I can protect you?"

Heiyunuo smiled and explained with Streaming Firefly, Streaming Firefly did not disdain, but actually started thinking seriously.

"Do they have their own channels for mercenaries?"

Streamer asked suddenly.

"No. They do not have the right to open regional passages because they are not obedient. For the country, protecting the area is the responsibility, but if they have a regional door, they don’t like to accept interrogation and monitoring, and they don’t know. What will happen."

Heiyu Nor paused, the communicator in his hand lighted up, and he began to send data to the streamer.

The data was clicked, streamer looked over, and He Yunuo explained:

"These are all early incidents about mercenaries. When they first started, they weren't large in scale, and they took over crazy missions that demanded money and life."
