Lu Chen couldn't help hearing the issue of radiation: "I will try to strengthen the walls as much as possible. Moreover, the world itself has been attacked by nuclear bombs many times, and it is full of radiation pollution. They are still fine, and their bodies have produced antibodies."

Lu Chen didn't understand this knowledge at all, so he could only talk about the heart of the dragonfly.

After the Dragonfly asked, he knew that he had asked too much, so he returned to the top to command without saying a word.

Shaking his head, no longer considering these things, Lu Chen considered how to strengthen the defense of the hole as much as possible.

The widest range of nuclear bombs attacks, and the most killing is nuclear radiation. The contractors don’t need to consider this. Shock waves and high temperature killing are the main faces of contractors.

After thinking about it for a moment, Lu Chen found that he could only pray that the enemy's nuclear bomb was small enough, and that he really didn't have much to do.

But even though there weren't many, Lu Chen still made a lot of preparations.

"Guo Jia, there are steel bars in the material room, send a batch of them." While expanding underground, Lu Chen asked Guo Jia to send someone to deliver steel.

Although he was a little confused about Lu Chen's request for steel at this time, Guo Jia quickly responded: "Okay, sir, I'll send it to you."

When Lu Chen ordered, the cave had actually expanded a lot, and it was so convenient for Lu Chen's earth-type superpower to dig a cave.

Of course, this defense is not complete, it can only be regarded as an ordinary cave. Living for a day or two is fine, but trying to block the attack of a nuclear bomb is like a dream. Lu Chen also needs to reinforce it.

But the space has been vacant after all, and refugees outside have lined up to enter the cave.

Lu Chen, the refugee who came in, also took a look. All the refugee children came in first, were wearing thick protective clothing. When all the children came in, the others slowly came down.

Their performance made Lu Chen sigh, and his compassion arose.

"Maybe it was not a mistake to help them." Looking at the children who stood quietly aside after coming in, Lu Chen suddenly had this idea.

Shaking his head and throwing these distracting thoughts out of his mind, Lu Chen stepped up the expansion of the space. It is not the time to sigh, and if you want to help them, it is undoubtedly the best way to build a stronger hole. Even if the nuclear bomb does not come this time, the hole can reserve a way out for them.

Thinking of this, Lu Chen was digging faster and faster regardless of his mental power consumption.

Time passed by little by little, because I didn’t know when the nuclear bomb would arrive, and the contractors and refugees were very busy. Of course, with the mercenary captain and Guo Jia’s command, although it was a bit busy, the order was still very stable.

There were hundreds of people, but if they were in an orderly manner, it would not take much time. Ten minutes later, everyone entered the space excavated by Lu Chen.

At the same time, Guo Jia also reported on the situation of the base like Lu Chen.

"All the doors in the base have been closed by us, and the automatic weapons and laser traps have been opened. Even if the enemy attacks at this moment, it will waste some time. That time is enough for us to return to it."

Nuclear bomb attack is just a hypothesis of Lu Chen and cannot be confirmed yet. Therefore, Guo Jia also considers other issues that may arise.

Of course, this arrangement was just for the sake of precautions. He actually trusted the nuclear bomb attack that Lu Chen predicted.

There is a precedent for the use of nuclear bombs by the Umbrella Company. The destruction of the bear market in the original plot is the best interpretation. With this precedent in front of it, how could the contractor dare not take it seriously?

After listening to Guo Jia's report, Lu Chen nodded clearly, and then he started to give orders.

"Hold the steel bars and steel plates on the ground, and they will serve as the pillars of this underground hollow."

The innate hardness of steel bars is much stronger than that of soil. Even if Lu Chen can make soil like steel bars, it would be a waste of Lu Chen's mental strength and time. Therefore, using steel bars and steel plates to bear it also appeared in Lu Chen's mind.

In order to allow the hole to carry hundreds of people, Lu Chen dug very much, and without strong support, it is very likely to collapse under the enemy's attack, so he did not dare to neglect it, so Lu Chen and the others strengthened it together.

Of course, when it comes to being together, they are just trying to help Lu Chen. They stand up the steel bars, and then Lu Chen will cover the main body of the steel bars with mud, and then activate superpowers to make the soil solid. In this way, the steel bars wrap the soil and make its defense reach its peak.

After that, Lu Chen kept strengthening. During this period, the snow girl's ice bird was observing the situation in the air. If the nuclear bomb really attacked, the ice bird would also crash into it as soon as possible. Being able to intercept it in mid-air is the best choice. Although high-altitude explosions will have a great impact on the ground, they are much better than on the ground.

Time has been passing, and soon, half an hour passed. At this time, Lu Chen's mental power had been consumed. He used all his mental power to reinforce the soil. At this time, the soil had all turned into hard rocks. Even so, Lu Chen was still a little worried and used his skill dungeon technique to strengthen the surrounding walls wildly.

There are still half an hour left for Lu Chen and the others to go back. The other contractors have smiled. Their gains in this world are quite big. No one has gained tens of thousands of survival points. This time it is equivalent to their previous worlds. So many gains are also a huge sum of money for them.

But at this moment, Lu Chen still dared not relax. While extracting the mental power stored in the magic crystal, Lu Chen stepped up the reinforcement around the wall.

Ten minutes later, the nuclear bomb still did not arrive, but a bad news came, Iron Man, Hawkeye and the others had been discovered.

"Damn it, I didn't tell them why this happened when I kept them away from the bear market." Lu Chen was a little angry when he heard this news.

Although Lu Chen had a good impression of the two of them, to be honest, Lu Chen was not particularly concerned about their life and death. It was just that their deaths, Lu Chen would also be reimbursed. This was something that Lu Chen could not bear.

Seeing Lu Chen furious, Guo Jia sighed helplessly: "It's useless. I don't know how the enemy's last plane mastered the invisible technology. Iron Man and Guo Jia have been under their surveillance. They can't escape no matter how they escape."

After hearing Guo Jia's words, the Viper tried to comfort him: "If the enemy only has one plane, Iron Man and Hawkeye should be able to deal with it."

The poisonous snake's words also made Lu Chen feel a little confident. But Guo Jia, who was in charge of contact, shook his head: "Just just now, the convoy of the Umbrella Company went directly to paralyze them. They had surrounded the Iron Man and the other two outside, and the two or three hundred soldiers were all heading towards them."

This sentence made Lu Chen silent. This time it was Lu Chen's responsibility. He wanted to send someone to monitor the Umbrella Company, and the Umbrella Company took the opportunity to remove the two of them.

At this time, Lu Chen could not help them. It was too far from the bear market here, and even if it was over, it was too late. All Lu Chen could do was pray.

After thinking for a while, Lu Chen said, "Not two or three hundred people attacked directly, but surrounded him in dispersed ways. It seems that the Umbrella Company does not want to kill them on the spot. Tell them that if they really can't resist, just surrender."

Lu Chen felt that the Umbrella Company was still very interested in "special humans" such as contractors. They might just catch contractors. They didn't want to kill them, which gave Iron Man and their hope of escaping. After all, the contractors' mission is not to destroy the enemy, but to survive. As long as the time is over, they can return to the nightmare space.

"I understand, sir, I will tell them not to fight to the death." Guo Jia's tone was a little worried at this time. His relationship with Iron Man was pretty good.

After Lu Chen said this, he stopped paying attention to them. He couldn't help. If he thought about it more, he would only add to his worries. Of course, this is also because the relationship between Iron Man and Lu Chen is not very close. If the dragonfly is killed, Lu Chen will definitely not be so relaxed.

At the same time, Lu Chen was also a little worried.

"The Umbrella Company did not let Iron Man and others go, and Qi Qian and Xiao Hua are also being hunted down. I believe the space will not let us go. The chances of nuclear bombs coming are getting bigger and bigger, and of course, other situations cannot be ruled out."

While thinking about this, Lu Chen stepped up the reinforcement of the base.

At the same time, dozens of steel and stone pillars wrapped in soil have been erected in the open hall, which are the main force supporting the hall.

Lu Chen kept strengthening the soil on his head, and continued to strengthen it into obsidian Lu Chen before he felt relieved.

Obsidian is different from ordinary stones. It is a magic material. This material has no other function, but it is a little hard and has a strong resistance to high heat and cold.

Only by using them to block the high heat and shock waves brought by nuclear bombs can Lu Chen feel at ease.

After doing all this, more than ten minutes passed. At this time, there were only ten minutes left before returning to space. As long as you hold on, Lu Chen and the others can survive.

While Lu Chen and the others were anxious to wait, Guo Jia suddenly heard a message about Iron Man and the others.

"The Iron Man and the others have escaped, but I can't contact them anymore, and I don't know where they went." As if seeing Lu Chen's doubts, Guo Jia explained: "The Iron Man has a random teleportation scroll, and he relied on it to teleport away."

The teleportation scroll belongs to the space category, and space props are one of the most precious props in Nightmare Space. At the same time, most of the space skills are B-level, A-level, and few C-level.

As the name suggests, the random teleportation reel means that the teleportation location is random. Such reels have too many uncertainties and may even be transmitted to the sky and the flame slurry. Under normal circumstances, almost no one uses it.

Of course, although there are too many uncertainties in such props, they are cheaper than scrolls in designated locations, and when they cannot escape, these scrolls can save their lives. As for whether they will encounter danger after saving their lives, they will leave it to fate.

However, after hearing Guo Jia's words, Lu Chen relaxed a lot, but he forgot something. These contractors are all seeds of the top team, so how could they not have some props to save their lives?

Although their props are not as precious as Snow Girl, they should be safe from their lives. Lu Chen thought they were too weak.

What Lu Chen needs to worry about is Dragonfly and Vivian. They are not strong enough, and their life-saving props are not very good. The chance of death in danger is too high.

At the same time, Lu Chen also thought that after he went back, he must buy some such props, and even if he couldn't use them himself, he could give them to the dragonfly.

While Lu Chen was thinking about this, the passage of time did not stop, and soon five minutes passed.

The sky in the ice mirror was already turning white at this time, and the sun was about to come out. When the sun came out, they could leave.

It was the last five minutes, and at this moment, Guo Jia and the others did not relax, but became nervous.

The attack of nuclear bombs is not like they set fire to the forest. With time to brew, it takes only a moment to destroy them. How could the contractor have the heart to relax by being threatened by such a terrifying weapon?

Lu Chen had already taken action at this moment. He had secretly summoned the ground-hiding beast, just under the feet of the dragonfly.

After looking at several worried children in the hollow hall, Lu Chen thought about the fact that he was taken in when he was a child. If he had not been taken in at that time, he would not have lived now.

This made him feel compassion. For the first time, he did not think about leaving on his own initiative, but was preparing to resist it first. If he could not resist it with all his strength, Lu Chen could only apologize.

He looked at the empty situation again. The dragonfly was by the children at this moment, comforting them, which made Lu Chen hesitate for a moment, and then he made up his mind.

If you really can't stop them, just bring those children with you. They are not big, and the upgraded earth-hiding beast can bring them with you.

Of course, Lu Chen was also praying that the nuclear bomb would not come so that they could escape the disaster.

However, Lu Chen himself didn't believe it if he had passed the task so easily.

Under anxious waiting, time passed slowly like the passing of the year, and Lu Chen was almost counting seconds.

The main reason is that the nuclear bombs are too famous, and Lu Chen and the others do not know the equivalent of the nuclear bombs sent by the Umbrella Company. They are afraid of it, so it is natural to have this feeling.

After a long wait, less than two minutes passed.

The snow girl could no longer hold back her breath. The scene on the ice mirror kept changing, which was caused by her controlling the ice bird's continuous turning.

But this time, Lu Chen did not stop her, and Lu Chen also wanted to know whether the attack would come and where it would come.

One more minute passed, and two more minutes left, they could return to space.

But at this last moment, the enemy's attack arrived. To be continued.
