Li Lechen heard Wang Jin's footsteps when he first arrived at the community, and also heard him asking around about his apartment building. So, he wasn't surprised at all that Wang Jin was knocking on the door.
So when Wang Jin came in, Li Lechen only paused for a moment before continuing to type away on the keyboard.
Zhou Mi greeted Wang Jin in the living room and was about to call Li Lechen, but Wang Jin stopped her, saying, "Don't disturb him."
The two then entered the study together and, sure enough, saw Li Lechen intently working on the computer.
Wang Jin nodded happily.
Zhou Mi rolled her eyes.
Since returning from the hospital, Li Lechen has either been sleeping or playing games whenever I see him, so I guess he's planning to drop out of school.
It's such a waste of all my hard work. I've been taking notes diligently for the past two months, and I even prepared an extra copy of the practice tests.
Seeing Wang Jin's demeanor, Zhou Mi decided not to expose him. She watched as Wang Jin sat down on the small sofa in the study, and then sat down next to him as well.
Wang Jin pulled out a stack of papers from his pocket. On them was a small half-paper, printed in Song typeface, titled "The Impact of Human Activities on Biological Evolution".
Zhou Mi was somewhat puzzled.
He seems quite profound; is he here to discuss academic matters with Li Lechen? What's their relationship? However, it seems Li Lechen surprisingly attended Wang Jin's lecture last time. Perhaps they really do have some connection.
Wang Jin didn't explain anything, but became excited again when he saw the content once more. Although he had read it countless times, he couldn't help but read it again. At the same time, he didn't forget to point out some key points to Zhou Mi.
Despite her various speculations, Zhou Mi's gaze remained fixed on the thesis.
"The evolutionary effects of human activities are gradually becoming apparent in plants and animals. Some are caused by global human intervention and climate change, while others are caused by localized pollution and increasingly dense urbanization..."
"...Since ancient times, fishermen have followed the rule of catching big fish and releasing small fish. But one point has been consistently overlooked: the small size of small fish is not necessarily due to their short growth period, but rather because their inherent characteristics preclude them from developing into normal, larger individuals. This is an unintentional process of artificial selection, resulting in the survival of increasingly inferior fish species..."
"...In European waters, fish are getting smaller and smaller. Observations have shown that some fish have shrunk by half in size in the last decade or so, the proportion of small fish in the waters is gradually increasing, and the organs of fish are generally shrinking, with fish populations decreasing by 60%. Pessimists believe that among the fish species currently being caught, 29% are already being caught at less than 10% of their peak levels. I believe that if this trend continues, global fisheries will completely collapse by 2056."
Wang Jin's finger stopped here, and he clicked his tongue and said, "I have been predicting 2048, but his prediction is 12 years later than mine. However, after I recalculated, I found that I missed the protective measures that the government will take after the fish resources are rapidly depleted. Therefore, adding these 12 years is absolutely necessary."
"???"
Zhou Mi didn't understand for a moment, and after a long pause, she asked, "You mean these were written by Li Lechen?"
"certainly!"
Wang Jin looked smug, as if Li Lechen was already his prized student.
Zhou Mi was speechless for a moment, and twitched her lips: "Could it be that you found it on Baidu?"
After saying that, Zhou Mi immediately got up to see what Li Lechen was doing, typing away on the computer keyboard.
They're probably playing games!
Wang Jin stopped him again: "Please don't disturb him. It's a terrible thing to have your train of thought interrupted."
Zhou Mi was helpless.
She's been spending time with Li Lechen these past few days. He hasn't been doing anything productive since he came back, but everyone's been lenient with him because of his health. It's absolutely impossible that he's doing any academic work.
I just don't know why Dr. Wang Jin is so certain.
There was nothing she could do. This guy had a full head of white hair and was a PhD from some national-level research institution. He came to Li Lechen's house so excitedly, and he even brought a piece of paper that he probably copied from Baidu. He insisted that Li Lechen was a genius. Plus, Zhou Mi was at someone else's house, so she could only go along with it.
Wang Jin continued to marvel at the half-finished paper.
"...Urbanization is perhaps humanity's most obvious impact on the Earth. Plants and animals living in cities are constantly evolving to adapt to the environment modified by humans..."
"...In the city, there is a type of annual chrysanthemum whose seeds are larger and heavier than their wild counterparts. Previously, these seeds were dispersed by wind, scattering everywhere. Lighter seeds are usually an advantage, but in the city, the opposite is true. If blown further by the wind, they might land on distant concrete or asphalt surfaces, unable to grow. Heavier seeds, however, can land directly in the soil around the plant, promoting the continuation of the population. There are also some weeds growing in the cracks of urban brick roads that, compared to their wild counterparts, no longer disperse their seeds. It is foreseeable that by around 2100, more than 80% of plants will no longer produce seeds..."
Wang Jin then emphasized the date of the prophecy.
"That's a bit far-fetched. Plants that don't produce seeds become extinct in less than a hundred years? That's too exaggerated."
Zhou Mi didn't know why, but she found herself engrossed in watching it.
