Zhao Yan originally planned to go fishing by the White Dragon Waterfall, but after inspecting the environment on the spot, he decisively chose another bay with gentle water and a large bamboo forest.

As a visitor to the earth who has long been accustomed to enjoying the life of the industrial age, Zhao Yan almost made the same super humiliating mistake as "why not eat minced meat".

In this world where there is no carbon retractable fishing rod, the relatively lightest bamboo rod has become the most suitable material for fishing rods.

Of course, there was no need for Zhao Yan to do it himself, and the guards scattered around divided two people and cut back a large bundle of bamboo poles of moderate thickness in the shortest possible time.

However, in order to experience the fun of fishing, Zhao Yan personally went to dig up earthworms in the silt, and used those earthworms that were dug out of the silt, which frightened Li Zixuan and couldn't stop screaming.

It was the performance of the little miracle doctor Jiang Xinyue that made Zhao Yan a little impressed, she was not afraid of earthworms at all, but rolled up her sleeves and teased the earthworms.

"Erlang, isn't it a little too much to hurt the lives of these earthworms just for fun? Everything has a spirit, and after doing too much of this kind of thing, there may be retribution. ”

After playing for a while, Jiang Xinyue said.

"Sister Xinyue, it's actually not as serious as you think, we just need to cut off the middle part of these earthworms' bodies, and then put the remaining two heads back into the ground, and it's fine. ”

Zhao Yan explained casually.

"Why is there nothing going on......? It's going to be more cruel, right?"

Jiang Xinyue frowned slightly.

"No, no, no, earthworms are different from us, they can regenerate quickly after their bodies are broken. And the most amazing thing is that when the earthworm is cut in two ends and regenerates, it will become two earthworms, not only half of them will live, so I said what I just said. ”

Zhao Yan hurriedly explained.

"Is that really the case? Why I've never heard of anything like this?"

Jiang Xinyue was still a little puzzled, and she asked suspiciously.

Because you haven't taken nature classes and biology classes, Zhao Yan said with a heart.

Of course, the heart can only be the heart said, Zhao Yan's action was really digging out the earthworm and rummaging through, and then found a piece with obvious scars on the body.

"Look at Sister Xinyue, this earthworm has been broken into two parts before because of some accident. As for what earthworms can regenerate, I can't tell the truth, but I've really done experiments before, so I'm pretty sure this kind of thing is real. ”

Zhao Yan really didn't lie, he did do this experiment - in the sixth grade of elementary school before the time crossing.

At that age, Zhao Yan was full of interest in nature and science, and at that age, it was the best age for ordinary bear children to be hungry for nature and scientific knowledge, and when they were older, they would gradually forget the spirit of pursuing science because of too many things.

Of course, when Zhao Yan was his age, there was no time for Warcraft and League of Legends, which was also an important reason why he was extremely interested in natural science.

"Experiment?

Although she has long passed the age of a bear child, in addition to not being afraid of earthworm accidents, Jiang Xinyue, who is full of ladylike temperament, still has a studious spirit of asking questions if she doesn't understand.

"It's just ......" Zhao Yan thought about it, and finally organized the language to answer: "It is to prove something, and the verification process that is common sense and universal significance is deliberately designed." ”

"For example, in order to verify that earthworms can be regenerated, I found a special pot and screened it to make sure that there was no soil from other earthworms in it, and then put the experimental earthworms cut into two sections. I then covered the pot with a breathable lid, and after a while searching the dirt to find two scarred earthworms, an experiment that no one can disprove in fact. ”

Zhao Yan took his earthworm regeneration experiment as an example and answered in detail.

"I understand, Xie Lu, thank you for your answer Erlang, you are really ...... Genius!"

The experimental steps designed by Zhao Yan were filled with brilliance in Jiang Xinyue's eyes when she listened.

As a healer, Jiang Xinyue has always been troubled by many things, and she has been looking for solutions to those things, but she has never been able to find a particularly good solution.

And at this moment, Zhao Yan's explanation of the experiment was simply a sentence that woke up the person in the dream and made Jiang Xinyue suddenly enlightened, so she did not hesitate to use words like "genius" to describe Zhao Yan.

If it weren't for the fact that the conditions didn't allow it at this moment, I am afraid that Jiang Xinyue would leave everyone behind at this moment and immediately design and carry out her own experiments.

It doesn't matter, you will be able to go back in two or three days, and there is a buffer time of two or three days, isn't it just enough to design the test steps that Jiro said are "common sense and universal", isn't it?

Jiang Xinyue said to herself.

"It's amazing that such an ugly earthworm can turn one into two. Well......" Li Zixuan looked at the earthworms dug up by Zhao Yan from a distance, and said thoughtfully: "Then if someone digs earthworms and cuts earthworms every day, will there be a day when the ground will be full of these ugly insects?"

"Ha Luha, this kind of thing - of course it can't happen!" Li Zixuan's childish thought made Zhao Yanha laugh: "If someone really does this, then those little birds will be the happiest." ”

"Birds?"

Li Zixuan's eyes were full of confusion, she couldn't understand what this kind of thing had to do with the bird.

So, Zhao Yan briefly gave everyone a brief introduction to the concept of food chain.

"It's funny. ”

After listening carefully to Zhao Yan's popular science lecture, Li Zixuan, who was full of interest, made such an evaluation.

"In other words, the sudden increase or decrease of any kind of living beings is not necessarily a good thing for the entire world realm, is it?"

Zhao Pu, who also listened to Zhao Yan's food chain science, obviously had deeper thinking, rather than just listening to anecdotes like Li Zixuan.

"Yes, theoretically yes, but I personally think that nature has a strong ability to rebalance, to put it simply, it is to break first, and then to stand. ”

Zhao Yan casually said his personal view of the world...... part.

"First it will be broken, and then it will be ...... What?"

Zhao Yan clearly saw that his golden-thighed brother Zhao Pu was visibly shocked after listening to what he said, and then he stood in place like a wooden chicken.

Belch?

What's going on?

Zhao Yan was slightly frightened, if something happens to this brother with golden thighs, he doesn't have to worry about what he will do in the future, he just needs to be a flying eagle lackey ** good family!

"Sister Xinyue......"

With such thoughts, Zhao Yan fell his gaze on Jiang Xinyue anxiously, and rushing to the doctor is never a compliment, but instinct.

"Shh——!h

Jiang Xinyue hurriedly made a boo gesture towards Zhao Yan, and then said in a very low voice-

"Erlang, your brother is breaking through the martial barrier demon, don't disturb him!"
