The middle-aged man and his son Xiao Wu who were in the underwater bubble heard the footsteps by the lake and gradually moved in the direction of the woods, and the whispered conversation between the two people walking at the end of the line gradually came.

"Director Wang, the 'white' family just now is all dead this time, are we doing a very clean and beautiful job of cutting the grass and eradicating the roots!

"It's a doctor, it's not white!"

"Cut, he is a spy when he comes back from overseas, and he is a traitor when he comes out of prison! He has been in a foreign country well, why should he come back? Those who come are not good, and those who are good do not come, what kind of doctor's title they got from foreign countries is white to us, reactionaries!"

In the blister, the middle-aged man's face was still very desperate at the moment, and he heard that the sound above had gradually disappeared. He turned to Xingze and said, "Little comrade, you saved me and Xiao Wu, right?"

Xingze looked at him, nodded, and did not speak.

The middle-aged man looked around and asked, "How did you do that?"

Xingze raised his hand lightly and threw over something like a whistle. The middle-aged man hurriedly caught it, carefully held it in his hand, and observed it carefully, "This, what is this?"

"The equipment for blowing this bubble!" Xingze replied, without much explanation.

The middle-aged man studied the bubble blowing equipment for a while, and then touched the bubble that seemed to burst at the touch of a button, but was actually extremely solid, and then said, "Can it move in the water?"

"Yes, I can float it up right now and let you go home!"

“…… , then forget it, you better let us die!"

Xingze stopped urging the bubbles to float in his hand, and looked at the middle-aged man with a little puzzlement.

"Little comrade, if you are not really desperate, who doesn't want to live well! But now Xiao Wu and I have not done anything wrong, but we have been dragged out to humiliate endlessly from the spirit to the body, and this kind of life is not as good as dying with dignity. So, I'm sorry, little comrade, although you are kind enough to save us, but you can't save your life for a while!"

Xingze fell silent again, and he motioned for the two to sit down in the bubble as well. The three of them sat silently opposite each other in the wonderful bubble, and the middle-aged man was still looking at the bubble and the bubble launcher in his hand with curiosity.

Xingze suddenly asked, "What if I send you abroad?"

The middle-aged man said without thinking: "When I came back from abroad, I wanted to use the knowledge I had learned to serve the country and contribute to national construction." But I don't want to be labeled as a collaborator and traitor to the country because of this, and now if I go abroad again, I'm afraid that this hat will be fastened, and I will never have a chance to do anything for the country again!"

After Xingze heard this, he asked again: "Then I will send you to the depths of the forest far away from the people, where you will live for a while, and then return to human society after this storm has passed?"

"If I'm just trying to live, you're doing all the good things, but I think people don't just live to eat and sleep, they have to do something meaningful for the country and the people. If I live away from human life for thirty or fifty years or more, when I return to human society again, my life's learning may have long passed, and I will still live a life of eating and waiting for death, don't do it!"

Xing Ze's eyes widened at this time, and he said in his heart that he had never seen such a hypocritical suicide, so he simply said: "Okay, since you are so bent on death, I will fulfill you, and I will remove the bubble in a while, and you will die." You can't count me as a murderer, right?"

The middle-aged man immediately waved his hand, "No, it will definitely not count you as a killing, and Xiao Wu and I will thank you." But I have one last small request, I wonder if you can agree to help?"

Xingze still said expressionlessly: "Okay, you say, if I can do it, I'll help you do it, if you can't do it, you should finish it in the next life!"

"Yes, you can do it. The middle-aged man touched the wall of the bubble and asked: "What is the principle of this bubble, how can its wall be so resilient, it contains three people and it will not break at all, and we have been here for so long, and the oxygen here does not seem to have decreased?"

Xingze couldn't laugh or cry a little, this middle-aged man is simply a hundred thousand humanoids, all of them are already dying, and he still has the heart to ask a bunch of scientific questions that he doesn't want to do.

"It's not just an ordinary blister, it's strictly a living thing. Its earliest prototype was a vesicle-like inclusion found in phototrophic, non-flagellated motile aquatic bacteria, which we cultivated into super-large blisters with strong walls because of the protein that encased them on the outside, which is very tough, and which produces oxygen through photosynthesis itself. ”

After listening to Xingze's more obscure explanation, the middle-aged man's eyes lit up, he couldn't help touching the blister again, and suddenly stepped to Xingze's side, grabbed one of his arms, and asked, "This is the blister extracted from cyanobacteria?"

Xingze was taken aback by his enthusiastic actions, and subconsciously pulled out his arm, and then explained: "It's not extraction, how can such a small blister be made so big, it can only be said to be an imitation or genetically modified." That's pretty much how it came about, and I don't really know about it, I'm just an applicator, and I don't really know how it works. ”

"As far as I know, there is no technology in the world that can make this kind of thing, where did you get this?" the middle-aged man continued.

"Don't you want to die, why are you so interested in this bubble, does it mean anything to you?" Xingze finally couldn't stand the middle-aged man's question, and began to ask rhetorically.

"Ah, no, I'm just researching biological genetic modification, this bubble of yours has broken through the world's most advanced level, this is a world-class scientific research achievement! If I can figure this out before I die, I will be blinded by death." ”

Xing Ze looked at the man in front of him, although he was full of white hair at this time, his eyes were shining, and his face was excited, which was completely different from the desperate frustration that was full of lovelessness before.

Xing Ze's heart suddenly moved, and he said: "Okay, you two don't have to die, I have a place, not only is there no political struggle, but there are also many things for you to study and transform, and it will definitely make your hero useful!"

"Huh, where is it?" the middle-aged man was stunned for a moment.

"It's my hometown, but you may not be able to return to your home for a long time. ”

"Are there really a lot of research projects? Are you well equipped, what are the most cutting-edge projects on your side, and what level is ?......?"

Xingze interrupted the hundred and one thousand whys with a wave of his hand, "Okay, I know your decision, you can go with me!"
