"Before the Calamity, the human body was so weak!"

After Ling Hai turned the pages of the book in his hand, he stopped and sighed.

"The Great Survey of Human Physique Before and After the Calamity" is the name on the cover of the book in Ling Hai's hand at the moment. The book, which Ling Hai borrowed from the internal library of the Ascendas Biological Research Headquarters, tells the history of the evolution of the human body before and after the Calamity. From this book, Ling Hai learned about the physical fitness of humans before the Calamity. It said that before the calamity, an ordinary healthy adult man weighing 60 kilograms had an average deadlift of only 100 kilograms, an average speed of 100 meters was only 7.2 meters per second, and an average punch power of only 280 kilograms. Such physical fitness is changed to today, and the body is severely stunted. You must know that even Ling Hai, who is not known for his physical fitness, now has an average deadlift of 180 kilograms, an average speed of 10 meters per second of 100 meters, and an average punch power of 500 kilograms. Such a big gap had to make Ling Hai sigh like that.

What caused the drastic changes in human physical fitness before and after the Calamity? Ling Hai continued to read with questions.

Time passed silently in the words, and by the time Ling Hai finished reading the entire book, it was already 13 o'clock at noon, and he had been reading it for more than 4 hours. After reading "The Great Survey of Human Physique Before and After the Calamity", the doubts in Ling Hai's heart were still not completely resolved. Because the book just lists a lot of data and history, giving a few speculations. Until the end of the book, it does not give a scientifically accurate conclusion.

It states that the period of upheaval in the human constitution is from 30 to 50 years of the Calamity. During this period, the human constitution underwent a radical change, almost rising vertically from one step to a higher level. In the thousands of years of history before the 30 years of the Cataclysm, the increase in human physical fitness was less than 1 percent of that of the period of upheaval.

30 years ago, the physical fitness of human beings was basically as weak as Ling Hai thought, and compared to the current one, they were all severely stunted. There are occasional special cases, and in terms of data records, they are only a little better than Ling Hai.

It was not until 50 years after the Calamity that the changes in human physical fitness began to stabilize.

Why the upheaval?

One of the speculations it gives is that the other world opened up by artificial wormholes has changed the ecological environment of the planet after coming into contact with the planet, which has promoted the evolution of human beings. This speculation has the most supporters, because the appearance of wormholes is indeed the biggest variable that led to human evolution. Without artificial wormholes and extraterrestrial creatures, humanity may not have such a rapid evolution for thousands of years. After the appearance of artificial wormholes, other animals and plants on the earth have also evolved to varying degrees, which is another evidence for this speculation. As for why the drastic changes began in the 30th year of the Calamity, why it was not the first year of the Calamity, not the 5th year of the Calamity, and why the 10th year of the Calamity began to change drastically, this is a point that scientists are still exploring and debating.

There is also a speculation that support is not low: humanity has developed its potential in the long struggle with extraterrestrial creatures. As we all know, adaptation is an instinct that all living things on earth have. When the human body is cut, it will stimulate tissue cells to accelerate division and proliferation and repair wounds. Weak insects evolve the ability to camouflage in order to survive. For thousands of years, all the creatures that have thrived to this day have vivid examples of the strength of resilience. The drastic change in human physical fitness is probably due to a command from the underworld to reach the depths of human potential, telling humans that they must evolve, otherwise humans will be exterminated by alien creatures. Thus, humanity awakened.

There were some other sporadic speculations, but in Ling Hai's opinion, some were too exaggerated, and some were too mysterious, and there was no value in thinking.

Closing the book, all in all, Ling Hai was still quite satisfied with this reading, this book gave him a lot of knowledge.

Today is July 25th, a day off.

Originally, in the past few days, Ling Hai has been allowed to move freely, and he can completely enter the city center to play, and even go home. But Ling Hai's choice was to stay in his residence and read books as usual, he had become accustomed to life in the laboratory.

Touching his already rumbling belly, Ling Hai went out. I didn't feel it when I was immersed in the book just now, but now that I finished reading it, the hunger pang immediately hit me, forcing Ling Hai to walk towards the cafeteria.

"Brother Shang, did you just come to dinner?" After Ling Hai entered the cafeteria, he happened to run into Shang Wen.

"Well, I'm late for the report." Shang Wen took the plate and turned around and said, "How was the rest?" There's nothing wrong with your body, right? You have to start a new round of experiments the day after tomorrow, and you have to take care of yourself. ”

"Well rested, nothing uncomfortable, thank you Brother Shang for your concern. The main reason is that the intensity of the experiment at the end of the first stage is not large, so the recovery is also fast. "Ling Haidao.

"That's good." Shang Wen said: "My meal is ready, I'll sit there, you can come over and talk after you finish the meal." Shang Wen finished and pointed to a spot in the cafeteria.

"Okay."

When the meal was finished and he sat down opposite Shang Wen, Ling Hai asked, "Brother Shang, I want to ask, do you know how long the second phase of the experiment will last?" ”

Shang Wen thought for a moment and said, "Your second phase of the experiment is to inject a strengthening reagent, right?" Then it's hard to say how long the experiment will be. It depends on your situation, ranging from 15 days to 45 days. However, I guess that with your 200% reagent utilization, the time experiment is likely to be 20 days. Of these, 15 days are spent on absorption and adaptation fortification reagents, and 5 days are spent on mating tests. Of course, everything depends on the actual situation at that time, you just have a good idea now, don't take it seriously. ”

"Mm-hmm, that's still a lot of time before you leave the lab." Ling Hai nodded slightly.

"What's the matter, you want to get out of here quickly?" Shang Wen asked with a smile.

Ling Hai shook his head and said, "No, I'm not in a hurry to get out of here. I'm saying I'm glad there's still time for me to read more in-house books here. If I'm going to leave soon, I won't be able to finish the books I just borrowed. To be honest, if I wasn't a test subject, and if my family didn't owe money, I'd be willing to stay here for the rest of my life. ”

"The collection of books and materials here is indeed very rich, there are all kinds of things, and there is not much to hide. The library built by the First Consortium of the Alliance is a temple of knowledge that many scholars want to visit. It's a pity that only a handful of people can really come in. Like me, if I hadn't worked here, I wouldn't have had access to the headquarters library. Shang Wen agreed.

In small talk, the two quickly finished their lunch. Because they were fine in the afternoon, the two chatted side by side leisurely and went to the residence.

Walking in the corridor on the second floor, the cleaning staff pushed the cleaning cart and walked towards Ling Hai and the two. Because the corridor could not accommodate Ling Hai, Shang Wen, and the cleaning car passing side by side, Ling Hai had to stop sideways and wait for the cleaning car to pass. And at the moment when the cleaning car passed, Ling Hai suddenly caught a glimpse of the crack in the lid of the trash can, with half a piece of wallpaper sandwiched. The half of the wallpaper was the one that Ling Hai had seen in Jiang Xiaodong's room, a wallpaper made of his sister's photo.

Ling Hai frowned and watched the cleaning cart slowly move away.

"What are you looking at, so fascinating?" At this time, Shang Wen patted Ling Hai on the shoulder.

"No, nothing." Ling Hai said after coming back to his senses.

"There's my room in front, would you like to come in and sit down?" Shang Wen said, pointing to room 2006.

"No, Brother Shang."

"Okay, we'll see you the day after tomorrow."

"Brother Shang." Just as Shang Wen was about to close the door, Ling Hai suddenly shouted.

Shang Wen poked his head out. "What's the matter?"

Ling Hai seemed to think of something, and said, "Can I ask you something?" Can you help me find someone, his name is Jiang Xiaodong, and he is also here to be an experimental subject, in the third laboratory. I hadn't seen him in a long time, and I wondered if he had left headquarters. ”

"No problem, Jiang Xiaodong, the third laboratory, right? I'll call you later. ”

"I'm sorry for you, Brother Shang."

"No, trifles. That's it, bye-bye. ”

Ling Hai didn't want to be nosy, but when he saw the wallpaper and thought of Jiang Xiaodong's goodbye without saying goodbye, Ling Hai faintly felt that something was wrong in his heart, and he suddenly wanted to know if Jiang Xiaodong had left the headquarters, so he took the liberty of asking Shang Wen for help.
