"It's precisely because you're young that you have to be careful!"

Zhang Jianguo's face was filled with grief. "I heard from several senior professors that as soon as you came back, you locked yourself in the lab, working non-stop on experiments without even taking a break. How can your body handle this? Listen to me, you must rest on time every day. Don't overwork yourself!"

“Thank you for your concern!”

"I've told you so many times, from now on just call me Uncle Zhang. Calling me 'you' or 'your' sounds strange. Just call me Uncle Zhang from now on!"

Su Leyan smiled helplessly, did not refute in the end, and called out "Uncle Zhang".

Only then did Zhang Jianguo raise his eyebrows happily.

Seeing his old classmate so happy, Su Donghui couldn't help feeling jealous, but thinking that they had only met twice, he didn't dare to do what Zhang Jianguo did.

Su Leyan looked at Su Donghui and said, "Commander Su, the meteorites you sent are too few. We can only make two energy shields. The protection area is slightly larger than ours, but it only has a service life of three years!"

"After three years, the effect of the energy shield will gradually dissipate until it disappears completely. Detailed instructions are included here, and you'll understand at a glance!"

Su Donghui excitedly took the box from Su Leyan's hand. It was a palm-sized box, but inside it was an energy shield that could protect the base. It would be strange if he wasn't excited!

"Can I open it and take a look?"

He wasn't doubting it; he just wanted to see what the so-called energy shield was. Furthermore, this box was so small, could it really cover four hundred square kilometers? Regardless, it was truly too incredible to even imagine!

"sure!"

Su Donghui opened the box carefully with trembling hands. There were two beautiful metal buckles inside. If there was any difference, it was that the two metal buckles were exactly the same and very smooth. If you didn't know that these two metal buckles were energy shields, at first glance you would think they were just two exquisite metal buckles with no other characteristics!

Zhang Jianguo also stretched his neck, wanting to see the legendary energy shield, but he didn't expect that it was just two exquisite metal buckles. It was so sudden!

"Xiao Su, is this the energy shield?"

Zhang Jianguo muttered softly, "It seems to be no different from the space hub!"

"Of course it's different!"

Su Leyan raised an eyebrow and explained calmly, "Don't be fooled by their similar appearance. The internal structure is different, and the various production principles are also very different!"

Zhang Jianguo smiled awkwardly, "Xiao Su, we are both rough guys. We don't understand the principles you are talking about. We just need to know that this is an energy shield!"

"Ms. Su, on behalf of the Capital Base and all the survivors, I thank you!"

This time, Su Donghui saluted her. He knew that this small metal buckle would become a protective umbrella for their capital base. As long as they had it, they could breathe a sigh of relief.

"Commander Su, you're too polite. The apocalypse has arrived, and all of humanity is one. Not to mention, I was raised by the nation. If I have the ability, I will naturally serve my country. This is what I should do!"

"No matter what, I still have to thank Miss Su. If it weren't for Mr. Lu's inability to leave the base so easily, it would be Mr. Lu who came this time!"

"Before coming here, he asked me to tell Miss Su that if she wants, she can come to the Capital Base at any time. The Capital Base welcomes Miss Su!"

"I'll go when I have time!"

After getting what he wanted, Su Donghui did not stay in the Shuguang Base for long. He did not even see his son Su You and left directly by helicopter.

Five hours later, Su Donghui arrived at the capital base. When he came back, the secretary of the big boss had been waiting for him for a long time.

"The top brass at the base are waiting for you in the conference room!"

"I see!"

After getting off the helicopter, Su Donghui immediately followed the Secretary-General to the meeting room.

"Report!"

"Enter!"

Su Donghui pushed open the door and saw that the conference room was full of people. They were all important leaders of the base, and the heads of the military regions were all here.

Not only that, the big guys from the research institute were also in the conference room. It seemed that they valued the things he brought back from the Dawn Base very much.

Come to think of it, how could we not value such black technology!

"Chief, I'm back!"

"Um!"

The old man nodded with a smile, "Well done!"

"Tell me about it!"

Su Donghui nodded and told the truth without any exaggeration. Even so, everyone looked shocked after hearing it.

"Did you bring back the genetic modification fluid and nutrient solution?"

Su Donghui nodded and took out the space hub.

"This is the space hub Miss Su made. She claims to have used some kind of space-folding technology to attach it to some object. I don't quite understand, but this tiny space hub contains a hundred cubic meters of space, and contains both the nutrient solution and the genetic modification fluid!"

"Space Hub?"

"Space folding technology, what kind of technology is this?"

"How many more surprises does Miss Su have in store for us?"

The people in the research institute were shocked. They had never heard of the space folding technology. It was so amazing. How could such a thing be done? It was simply a miracle!

"Where's the energy shield?"

What the old man was most concerned about was the energy shield. After all, as long as the energy shield was in place, the base would be absolutely safe in a short period of time. Only when the base was absolutely safe would they have time to do other things.

When everyone heard this, they looked at Su Donghui with burning eyes. They also wanted to know whether Su Donghui had brought back the energy shield this time. After all, it was something that concerned the life and death of their base.

Su Donghui nodded, then took out the energy shield from the space hub.

"Miss Su said there were too few meteorites, so she could only make two energy shields. They're all inside. The usable area is 600 square kilometers, and the service life is three years. The instruction manual is also inside!"

As soon as Su Donghui finished speaking, the whole conference room was filled with heavy breathing. Everyone stared at the small box on the leader's desk. Inside was an energy shield that was related to the life and death of their base. How could they not be excited?

"Are you sure the usable area is 600 square kilometers?"

The area is even larger than they imagined, what a surprise!

Su Donghui nodded, "Miss Su said that the usable area of ​​these two energy shields is 600 square kilometers!"

The old man's breathing became heavy. Six hundred square kilometers was equivalent to the area of ​​a district in the capital. It could accommodate not only hundreds of thousands of people, but even millions of people. In this way, they would not be crowded in the small base!

"Okay, that's great!"
