The problem of radiation, Lu Chen was helpless when he heard it: "I will try my best to strengthen the wall, and besides, this world itself has been attacked by nuclear bombs many times, and it is polluted with radiation everywhere, they are all fine now, and their bodies have produced antibodies." ”

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

After the dragonfly asked, he also knew that he had asked too much, so he silently returned to the top to command.

Shaking his head, no longer thinking about this, Lu Chen thought about how to strengthen the defense of the cave as much as possible.

The nuclear bomb has the widest attack range, and the most killing is nuclear radiation, which the contractor does not need to consider, and the shock wave and high temperature killing are the main problems that the contractor faces.

Just thinking about it for a while, Lu Chen found that he could only pray now that the yield of the enemy's nuclear bomb was small enough, and there was really not much he could do.

But even if it wasn't much, Lu Chen still made a lot of preparations.

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

Although he had some doubts about Lu Chen's need for steel at this time, Guo Jia quickly responded: "Okay, sir, I'll send it down for you." ”

At the time of Lu Chen's command, the ground hole had actually expanded a lot, and Lu Chen's earth-based ability was too convenient to dig the ground hole.

Of course, it's just that this defense is not complete, this can only be regarded as an ordinary cave, it's okay to live for a day or two, but trying to block the attack of the nuclear bomb is tantamount to a fool's dream, and Lu Chen has to reinforce it.

But the space was empty after all, and the refugees outside had already lined up to enter the hole.

Lu Chen, the refugees who came in, also paid attention to it, and all the children who came in first were refugees. They wore thick protective suits and waited until all the children were in. The rest of the talent slowly came down.

Their performance made Lu Chen sigh, and the compassion in his heart also rose.

"Maybe helping them wasn't a mistake." Looking at the children who came in and stood quietly on the side. Lu Chen suddenly had this idea at this moment.

Shaking his head and throwing these distracting thoughts out of his mind, Lu Chen stepped up the expansion of the space, now is not the time to sigh, and if he wants to save them, it is undoubtedly the best way to make the hole stronger, even if the nuclear bomb does not come this time, the hole can reserve a way back for them.

Lu Chen, who was thinking like this, didn't care about the consumption of spiritual power. The speed of digging is getting faster and faster.

Time passed little by little, because I didn't know when the nuclear bomb would come, the contractors and the refugees were very busy, of course, there was the mercenary captain plus Guo Jia's command, although it was a little busy, but the order was still very stable.

There are hundreds of people, but if they come down in an orderly manner, it won't take much time, ten minutes later. Everyone entered the space that Lu Chen had excavated.

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

"We've closed all the doors in the base, and the automatic weapons and laser traps are all open, even if the enemy is attacking at this moment. It will also waste some time, which will be enough for us to return to it. ”

A nuclear bomb attack is just a hypothesis for Lu Chen, and it is not yet certain. Therefore, Guo Jia also considered other problems that might arise.

Of course. This arrangement is just in case, for the nuclear bomb attack predicted by Lu Chen. He actually trusts him a lot.

There is a precedent for the use of nuclear bombs by the Umbrella Company, and the destruction of the bear market in the original plot is the best interpretation, with this precedent in the past, how can the contractor dare to do the same.

After listening to Guo Jia's report, Lu Chen nodded knowingly, and then he commanded.

"Put up the steel and the steel plates on the ground, and they will be the pillars of this underground cavity."

The innate hardness of steel bars is much stronger than that of soil, even if Lu Chen can make the soil become the same as steel bars, but that would be too much of a waste of Lu Chen's mental power and time, so using steel bars and steel plates to bear also appeared in Lu Chen's mind.

In order to make the hole able to carry hundreds of people, Lu Chen dug it very much, and without strong support, under the attack of the enemy, there was a great possibility that it would collapse, so he didn't dare to slack off, and Lu Chen strengthened it with others.

Of course, they are all talking about it, but they are actually just giving Lu Chen a hand, they will erect the steel bar, and then Lu Chen will cover the main body of the steel bar with dirt, and then activate the ability to make the soil strong, so that the steel bar wraps the soil to make its defense reach the peak.

After that, it was the process of Lu Chen's continuous reinforcement, during this period, the Snow Maiden's ice bird has been observing the situation in the air, if the nuclear bomb really attacks, the ice bird will also crash into it as soon as possible, and it is the best choice to intercept it in mid-air, although the high-altitude explosion will also have a great impact on the ground, it is much better than on the ground.

Time has been passing, and soon, half an hour has passed, at this time Lu Chen's spiritual power has consumed more than half, he used all his spiritual power to strengthen the soil, at this time the soil has all turned into hard rock, even so, Lu Chen is still a little uneasy, and used the skill dungeon technique to reinforce the surrounding walls crazily.

There is still half an hour for Lu Chen and they can go back, and the other contractors have already shown smiles on their faces, their harvest in this world is not small, no one has the harvest of tens of thousands of survival points, this time it is equivalent to their previous worlds, so many harvests, it is also a huge amount of money for them.

It's just that at this moment, Lu Chen still didn't dare to relax, and while extracting the spiritual power stored in the magic crystal, Lu Chen stepped up the reinforcement around the wall.

Another ten minutes passed, and the nuclear bomb still hadn't arrived, but the bad news came, Iron Man, Hawkeye, and they had been spotted.

"Damn, I didn't tell them to keep them out of the bear market, why is this happening." Hearing this news, Lu Chen was a little angry at that time.

Although they fought together and lived for seven days, Lu Chen had a good impression of the two of them, but to be honest, Lu Chen didn't really care about the life or death of the two of them, but when they died, Lu Chen's B-level equipment would also be reimbursed. This was unbearable for Lu Chen.

Seeing Lu Chen's anger, Guo Jia sighed helplessly: "It's useless." The enemy's last plane didn't know how to master the stealth technology, and Iron Man and Guo Jia were always under their surveillance. The two of them couldn't escape. ”

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

The viper's words also made Lu Chen rise a little confident, but Guo Jia, who was in charge of the contact, shook his head: "Just now, the convoy of the umbrella company went directly over, just to paralyze them, they have already surrounded the two of them outside, and the two or three hundred soldiers are all heading towards them." ”

These words made Lu Chen silent, this time it was Lu Chen's responsibility, he wanted to send someone to monitor the umbrella company. The Umbrella Company took the opportunity to get rid of the two of them.

At this time, Lu Chen couldn't help them, this place was too far away from the bear market, even if it passed, it would be too late, and all Lu Chen could do was pray.

After thinking for a while, Lu Chen spoke: "Two or three hundred people did not attack directly, but scattered and surrounded, it seems that the umbrella company did not want to kill them on the spot." Tell them that if they can't resist it, they will surrender. ”

Lu Chen felt that the Umbrella Company was still very interested in the "special humans" of the contractor, and they might just catch the contractor. It's not that they want to kill, which gives the Iron Man hope that they can escape, after all. The task of the Contractors is not to destroy the enemy, but to survive. As long as they wait until the time is up, they will be able to return to Nightmare Space.

"Understood. Sir, I'll tell them not to fight to the death. Guo Jia's tone at this time was a little worried, and his relationship with Iron Man was not bad.

And after Lu Chen said this, he didn't pay attention to them, he couldn't help, and if he thought about it more, it would only add to his troubles, of course, this is also because the relationship between Tieren and Lu Chen is not very close, if the dragonfly is killed, Lu Chen will definitely not be so easy.

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

"The umbrella company didn't let go of the iron man, Qi Qian and Xiao Hua are also being hunted down, presumably the space will not let us go, the probability of the arrival of the nuclear bomb is getting bigger and bigger, of course, other situations cannot be ruled out."

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

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

The dirt above his head Lu Chen kept intensifying, until it was strengthened into obsidian Lu Chen put his mind at ease.

Obsidian is different from ordinary stones, it is a magical material, this material has no other effect, it is a little hard, and it has a strong resistance to high heat and cold.

Using them to block the high heat and shock wave brought by the nuclear bomb, Lu Chen can rest assured.

After doing all this, another ten minutes or so passed, and at this time, there were only ten minutes before the time to return to space, as long as they survived, Lu Chen and they would be able to survive.

And while Lu Chen and the others were waiting anxiously, Guo Jia suddenly came with a message about the iron man.

"Iron Man, they've escaped, but I can't reach them either, I don't know where they've gone." As if seeing Lu Chen's doubts, Guo Jia explained: "There is a random teleportation scroll on the iron man, and he teleported away by relying on it. ”

The teleportation scroll belongs to the space class, and the space props are one of the most precious props in the nightmare space, and most of the space skills are B-level, A-level, and rarely C-level.

As the name suggests, the random teleportation scroll is the location of the teleportation, such a scroll has too much uncertainty, and it is even possible to teleport to the sky and the flame pulp, and under normal circumstances, almost no one uses it.

Of course, although such a prop is too uncertain, it is cheaper than the scroll in the designated position, and in the case of no escape, this kind of scroll can save your life, and after saving your life, you will not encounter danger, and it is up to fate.

However, after hearing Guo Jia's words, Lu Chen relaxed a lot, he forgot one thing, these contractors are all seeds of top teams, how can there be no life-saving props.

Although their props are not as precious as the Snow Maiden, they should be safe to save their lives, and Lu Chen thinks they are too weak.

What Lu Chen needs to worry about is Dragonfly and Vivian, their strength is not strong, and the life-saving props are not very good, and the chance of dying in danger is too great.

At the same time, Lu Chen also thought about it, after going back, he must buy some such props, even if he can't use them, he can give them to dragonflies.

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 white by this time, and the sun was about to come out, and when the sun came out, they could leave.

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

The attack of the nuclear bomb is not like they set fire to the forest, it has time to brew, it only takes a moment, the nuclear bomb can destroy them all, threatened by such a terrifying weapon, how can the contractor have the mind to relax.

And Lu Chen had already taken action at this moment, he had secretly summoned the Retreat Beast, right at the feet of the dragonfly.

Glancing at the few worried children in the empty hall, Lu Chen thought of the fact that he was taken in when he was a child, if he hadn't been taken in at that time, he wouldn't be alive now.

This made his compassion activate, and for the first time, he didn't think about taking the initiative to leave, but was ready to resist first, and if he couldn't resist with all his might, Lu Chen could only apologize.

Glancing at the situation in the hollow again, the dragonfly was beside those children at the moment, comforting them, which made Lu Chen hesitate slightly, and then he made up his mind.

If you really can't stop it, bring those children with you, their size is not big, and the upgraded Retreat 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.

It's just that Lu Chen himself didn't believe that he had such an easy time to get through the task.

Under the anxious waiting, time passed slowly like days and years, and Lu Chen was almost counting the seconds.

The main reason is that the prestige of the nuclear bomb is too great, and Lu Chen and the others don't know the yield of the nuclear bomb sent by the umbrella company, and under the fear in their hearts, it is natural to feel this way.

The long wait lasted less than two minutes.

And the Snow Maiden was already a little breathless, and the picture on the ice mirror kept changing, which was caused by her controlling the ice bird's constant turning.

But this time, Lu Chen didn't stop her, and Lu Chen also wanted to know if the attack would come and where it would come from.

Another minute passed, and in two minutes, they were back in space.

But at this last moment, the enemy attack came. (To be continued.) )
