Omniscient and Almighty

Chapter 92

Zhang Lao didn't say much about how to get angry with food, he basically let Xu Guangling understand the term temporarily, and then today's lecture, um, seriously, it's a lecture, if you say it casually, it's just nagging, even if it's over up.

Today, Zhang Lao popularized the knowledge of colds for him, and then tested his understanding of Chinese history by the way, haha.

Xu Guangling has decided to take "Chinese History" as an elective course for some time to come.It's not that he wants to be good to Zhang Lao, but Xu Guangling feels that if he continues to come to Zhang Lao to listen to lectures like this in the future, historical knowledge may be very necessary.

Just take today as an example.

If he hadn't had some understanding of the interaction between the ancient Central Plains and the northern nomads, Zhang Lao's explanation would certainly not have been like this. — what would that look like?

Xu Guangling doesn't know, but one thing is certain, that is, it is definitely not as good as it is now.

His performance cannot be said to satisfy Mr. Zhang, but generally speaking, it should still be qualified.

But "qualified" has never been Xu Guangling's requirement. As I said before, not only "qualified" is not, but "excellent" is not. "Perfect" or close to perfect is.But Xu Guangling wasn't too demanding on himself, as in today's matter, passing is acceptable.

After all, it was quite a good thing that he had these knowledge reserves when things happened suddenly.

But today is today, and the future is the future. If it is still at a qualified level in the future, it must be something Xu Guangling cannot accept.Therefore, according to the needs of Mr. Zhang, it is necessary to put on the agenda to carry out corresponding additional supplementary lessons in a timely manner.

After the lecture, when Zhang Lao went to make tea again today, Xu Guangling followed, and then took over Zhang Lao's work in due course. Zhang Lao did not stop him, and let him come with a smile.

Instead of entering the study, the three of them just sipped tea in the living room as a rest.

And during this leisure time, Xu Guangling remembered how he felt when he practiced the four moves and one style today, and asked Mr. Chen: "Old Chen, when I practiced the style you taught me yesterday, did my body feel better? The feeling is particularly obvious, is there anything I need to pay attention to?"

Xu Guangling said, and then described his practice experience in more detail. Of course, the most important thing is that he seems to clearly feel the flow of Qi and blood in his body.

Xu Guangling asked this question to Mr. Chen, because Mr. Chen taught him, but after listening to what he said, it was Mr. Zhang who said: "Zhuoyan, I will answer this question for you, you first Go outside and get a leaf and come back."

Xu Guangling was slightly surprised, but immediately got up and obeyed.

And after Xu Guangling went out, to be precise, when he turned his back to the two old men and walked out of the small building, the two old gentlemen looked at each other in the living room, and there was a deep look in their eyes. Shocked, and even Mr. Chen, who is the "grandmaster of a generation", has obvious envy in his expression, let alone Mr. Zhang.

Then, Mr. Chen smiled wryly, while Mr. Zhang was helpless.

The next moment, the two old gentlemen turned their heads in unison, followed Xu Guangling's figure with their eyes, watched him walk out little by little, and then watched him come in step by step.

Being watched by the two old people and walking into the living room, Xu Guangling felt a little uncomfortable, but he didn't think too much for a while, "Mr. Zhang, do you think these leaves are useful?"

Zhang Lao always asked him to take a leaf back, because he didn't know Zhang Lao's intention, so Xu Guangling simply took three leaves, one was completely green, one was withered and yellow, and the other was half green and half withered.At this time, seeing his little cleverness, the two old people suddenly felt amused again. Mr. Zhang couldn't help but shook his head slightly, and said with a smile: "Okay, this one will do."

He reached out and took the half green and half dead one from the three leaves.

After Xu Guangling sat down, Zhang Lao said slowly: "Zhuoyan, living things are divided into three categories: microorganisms, plants, and animals. You should know it."

Xu Guangling doesn't know much about biological knowledge, but he really knows this. ——If he didn't even know about this, or if he forgot about it, all the biology teachers in his middle school and high school would be looking for him desperately if they knew about it.

Seeing Xu Guangling nodding, Zhang Lao continued: "Let's not mention microbes. Plants and animals seem to be completely different, but they actually have a lot in common. In nature, there are also many creatures that have both characteristics at the same time. .”

At this time, Mr. Zhang did not give an example, probably because Xu Guangling might not know much about it even if he gave an example.

But Xu Guangling nodded at this time, expressing his understanding, and took the initiative to show Zhang Laoxian two examples to show that he really understood: "Zhang Lao, piranhas and Venus flytraps should be what you said This type of creature?"

Hearing what he said, Zhang Lao nodded with a smile, and said:

"Plants and animals are just an expedient division made by the scientific community so far in order to better distinguish living things. Note that it is expediency, so seriously, it is not rigorous."

"Just like we now call a vegetable that can be eaten raw as 'lettuce', it is only called that as an expedient. Because if there are many vegetables that can be eaten raw in the future, and this is inevitable, what will happen then? What's the name? You can't call it 'Lettuce No. [-]' and 'Lettuce No. [-]', and go all the way down like this?"

Xu Guangling laughed.

"Zhuoyan, I say this to tell you that the difference between plants and animals is not as great as most people imagine, and they are not two completely different types. In essence, they actually have more in common. This means that What? Means that what is true of plants can sometimes be applied to animals, and vice versa."

"There used to be news that a tree was sick, and people gave it a 'suspended injection', and it was cured by this method. Have you heard of this news?" Mr. Zhang asked.

Xu Guangling had actually seen such news on the Internet, and there seemed to be more than one case, so he nodded again when he heard Zhang Lao's question.

"Okay, then we can start your question now." Zhang Lao said, and then he shook the leaf that he just took in his hand, "Zhuoyan, look at this leaf, these things on it Veins, if we use human beings as a comparison, what should they correspond to in the human body?"

This is simply asking Xu Guangling as if he was a kid in kindergarten!

Xu Guangling smiled wryly, but still didn't dare to answer too definitely. It doesn't matter if you get slapped in the face, the key is "knowing what you know, knowing what you don't know". , but he still asked in a questioning tone: "Blood?"
