Under Luo Shuang's sad gaze, the shelter made a rapid alarm ten minutes later, and then the ground was shaking, and those ordinary people who were unstable were knocked to the ground one after another, and they were crooked.

On the southeast, north, and west walls of the shelter, each of the four directions rose a water-blue light, protecting the entire shelter inside, like half of a water-blue bowl upside down on the ground, cutting off the connection between the shelter and the outside world.

"Ah~"

And at this moment, the pursuit of the red beetle also arrived, and the warriors who did not have time to enter the protective shield in a hurry were divided in half by the red beetle that caught up behind.

One after another, the red beetles slammed into the shield, only to bounce back in the next second. Again and again, the red beetle that was unwilling to give up frantically hit the protective shield.

Everyone held their breath, for fear that this last line of defense would also be broken, and what awaited everyone was the final extinction of the country, or even the extinction of the race.

"This is a relic from a technological civilization?" Luo Shuang asked sideways.

"Yes! It is that energy spar that can be used as the energy driving force to support the protective shield! It's a pity that time is too short, and we humans haven't had time to crack other products yet! Si Nan said with a headache, "That guy Gong Feng has been overwhelmed by those scientific and technological civilization heritages!" ”

"Then we're like a shrunken turtle locked in this blue tortoise's shell?" Luo Shuang couldn't bear to see the scene of the flesh and blood of those soldiers who were torn apart by the red beetles not far ahead.

"The storage of energy crystals is limited, and I don't know how long they can hold up. I'm ready to play at any time! "Sinan has already gathered all the personnel of the special combat team through the watch.

At this moment, Luo Shuang knew that the chief instructor of the Long Yan Special Combat Team was Wang Qingyun, and the three teams under the Long Yan Special Combat Team, the captain of the Blue Sword was Long Xi, and Sinan was the deputy captain! Recently, Long Xi stepped down from the position of captain of the Blue Sword because of his imminent breakthrough in cultivation, and Sinan was officially promoted to the position of the captain of the Blue Sword. The leader of the lone wolf brigade is Ling Hui, who is now ordered back, and is mainly responsible for the daily security patrols of the shelter. And the captain of the snow leopard brigade is the most mysterious and has not appeared so far.

No wonder Ling Hui and Sinan have been looking at the wrong eye, you must know that the three brigades are competing. Neither of them is convinced.

Could it be that this was developed by the civilization technology brought back from which scientific and technological civilization? Luo Shuang looked at standing on the high city wall. Sinan, who was nervously constantly paying attention to the pace of the red beetle's attack.

Luo Shuang jumped on the city wall lightly, standing side by side with Sinan, as far as his eyes could see, it was just a red beetle that had fled. It's just a pity for the warriors who haven't even returned to the shelter. I made more food from the mouth of the red beetle.

"The hosts. The support time of this shield will last for about ten days, and this is still not the appearance of higher-level bugs in the future, but I think this is relatively unlikely. Luo Shuang's game watch suddenly appeared with an intelligent voice. It turned out to be a long-dormant heart in the watch. Ever since this guy got into his watch, he has been silent, as if he is digesting and absorbing the technology on the earth, and he is also in the process of self-updating and automatic evolution. Now it seems that it is completely integrated with the technology on the earth, and the voice of the heart is more humane, and it seems to have been upgraded.

"Only ten days?" Luo Shuang was entangled in his heart, how good is this.

"If humans can thoroughly study particle cannons, or laser guns, it seems that there are still some chances of victory." Xinyi commented.

"What about the mech?" Luo Shuang remembered the mecha he debugged, maybe he didn't think it was time for the last hole card to appear.

"Mechs are good, but there are too few of them. Human beings have only researched mechas, but the supporting large-caliber lethal weapons have not been developed, and the firepower can't keep up, the mecha is just a stupid big man~" Xinyi analyzed with emotion.

"Is there a way?" Luo Shuang was simply anxious.

"Let me think about it, it will take some time to develop a particle cannon, but a neutron cannon may be possible......" thought to me.

"Okay, sort out the information, I'll go directly to Brother Wang!" Luo Shuang couldn't estimate much at this time, whether his behavior would expose his hole cards, whether it would arouse the suspicion of people with intentions, and even whether the relics of civilization he got by following Brother Wang last time would be found out, but Luo Shuang couldn't care about anything in front of the extinction of the country.

The diameter walked towards the scientific research institute of the refuge, where all the elite scientists who had taken refuge were gathered, and Rayong was among them.

I saw that Gong Yue and Wang Qingyun were leading this group of scientific research maniacs to frantically discuss the final plan of the mecha. And Gong Feng was busy acting as a note-taking guy.

"Brother Wang, can the mecha be confirmed?" Luo Shuang looked at the five tall and mighty mecha set up in the laboratory and asked with a smile.

"It just so happened that Luo Shuang came, just in time! Mention your opinion on Dragon One! If the shield can't withstand it, it's time for the mecha to show its majesty! Don't shirk piloting the mech when the time comes! They told me that your coordination, reflexes, and agility are the best. Wang Qingyun said.

"False! I don't think the weapons of the mecha are lethal enough! Luo Shuang said frankly.

"There's no way! The information we got last time was too far from the current technology on the earth, and it was impossible to develop the corresponding weapons in a short period of time. Conventional weapons on Earth today have limited lethality against insects above the Heavenly Rank, unless nuclear bombs are used! But that's the last move! The use of nuclear bombs means the beginning of human self-destruction! Wang Qingyun said helplessly.

"I have a copy of the information here, Brother Wang can let them look at it to see if it is feasible?" Luo Shuang solemnly submitted a piece of information to the past.

"Shuangshuang, don't make trouble, our time is precious!" Seeing this, Luo Yong interjected beside him, but he couldn't let his daughter watch the trouble without a whimsical whim.

Daughter Luo Shuang is studying pharmacy, but she is not a missile expert, what unique insights can she have?

"Oh?" Wang Qingyun actually doesn't know this, but it doesn't hinder the BT ability of a group of scientific research maniacs under him? Half an hour later, this information was confirmed by the lunatics! And with all the resources of the evacuation, you may be able to see the finished product in half a month! Because they don't want a heavy-duty missile like a nuclear bomb, but just a large-caliber lethal weapon mounted on the arm of the mech.

"Chairman, this, this information is true!" He Haoming, the most famous weapons expert in Huaxia Country, and the white-haired old man were trembling with excitement...... (To be continued.) )
