Chapter 45: Chapter 43: The 4th Generation That Must Be Overcome
Inside the enclosed space.
Looking at the three virtual items in front of him, Xu Yun’s expression was somewhat subtle.
Temporarily putting aside the Easter egg, from the description, it’s not hard to see that it should be something that needs to be triggered by combining with some real-life situations. There are currently no clues to make a judgment.
To Xu Yun, in light of his recent experience of achieving a 5 times zero critical hit with an 80% critical rate barbarian, there’s no guarantee he will ever activate an Easter egg in his life...
The agony of low luck, only those who understand will understand.
After temporarily putting aside the Easter egg, only two items remained.
First, was Little Niu’s Thought Experience Card.
How should I put it...
Without a doubt, it’s a good thing!
As a founding figure of modern physics, Little Niu’s intelligence is undoubtedly a towering peak in human history, conservatively placed in the top ten for sure.
Especially the 22-year-old Little Niu from 1665, probably no one in history could match him in battle.
Thus, the quality of this Thought Card is indisputable, the only concern is its usage time.
Half an hour, which for Brother Dong could mean 15 battles, but in solving problems, half an hour is quite a limited time period; it’s not much time, but not insignificant either.
Especially when facing some difficult problems, two or three hours are often necessary, and on some math forums, spending four or five hours on a problem is quite standard.
Therefore, once this Thought Card is used, it must be used wisely, timing is of utmost importance.
Then Xu Yun shifted his gaze to the piece of parchment, which supposedly contained the reward of the fifth-generation Imidacloprid formula.
Considering there’s neither a desk nor a pen in the space, making it unsuitable for research and calculation, Xu Yun thought for a moment and silently recited ’return’ in his mind.
Whoosh——
The space disappeared in an instant, and his consciousness returned to his little room.
After regaining his composure, Xu Yun didn’t rush to summon the Imidacloprid formula, but first looked down at.....
his own feet.
At this moment, his feet were bare, without shoes or socks.
Exactly.
The pair of Anta shoes, or the Brogue shoes gifted by Little Niu, both did not return with him.
Seeing this, Xu Yun couldn’t help but stroke his chin:
"So, items on me that meet specific conditions will travel with me to the Dungeon, but items from the Dungeon cannot be brought back?"
Then, he thought of something and looked at his ankle again:
The first time he visited William’s house, Little Niu once took him to chop wood, during which Xu Yun’s left ankle joint was pressed and swelled red, and over time it failed to subside, even forming an abrasion.
But right now, the skin on Xu Yun’s left ankle was smooth, showing no signs of pressure or abrasion.
Additionally, due to the 17th-century living standards over the past two weeks, Xu Yun’s body inevitably picked up some peculiar odor, and his clothes weren’t particularly clean.
But at this moment, these odors had long vanished.
Xu Yun glanced at the clock on the table, it was 4:27 in the afternoon, exactly as when he entered the space.
"So..."
"I soul-traveled to the 17th century, but items on me seem selectively to manifest in the Dungeon?"
"For instance, modern-styled things like glasses and clothing that existed technically in that era travel with me, while phones and earphones are automatically blocked?"
Xu Yun thoughtfully stroked his chin, after this comparison, the mapping relationship between the Dungeon and reality became much clearer.
It’s a pity that I didn’t think it through enough before, I should have tried to get a haircut at Little Niu’s place to see if my hairstyle would change after returning.
Then he came to the desk, extended his hand, and concentrated his attention to sense.
Zoom——
The next second, a piece of parchment gently fell into his hand.
On the parchment was a dense array of chemical symbols and Chinese characters, some of which had complex chemical structures that were dizzying at a glance.
However, as a doctoral candidate in biology, Xu Yun easily discerned the initial parts of the chemical structure.
C9H10ClN5O2, which is 1-(6-chloropyridin-3-ylmethyl)-N-nitroimidazolidin-2-ylamine, the scientific name.....
Imidacloprid.
It is a nitromethylene systemic insecticide, classified as a chloronicotinyl insecticide, also known as neonicotinoid insecticide, formally proposed at the 1991 United Kingdom Brighton Crop Protection Conference.
It acts on the nicotinic acetylcholine receptors, disrupting the insect’s nervous system transmission of chemical signals, primarily used for controlling pests with piercing-sucking mouthparts and their resistant strains.
In agriculture, it is mainly used for controlling aphids and leafhoppers, whereas in daily life its biggest application is eradicating various household pests.
Since its market introduction in 1991, it has rapidly gained popularity, spreading to over forty countries worldwide within just three years.
As of today, it can be said that where there is plant protection, there is Imidacloprid; currently, Imidacloprid is the world’s number one insecticide, with its global sales reaching 1.14 billion US dollars in 2014.
However, even such a product that has risen to the altar has not had an easy time these recent years.
Firstly, there is the issue of pest resistance arising from long-term use. With the widespread use of Imidacloprid, a large number of greenhouse pests have developed resistance to it—quite similar to the inevitable resistance developed with widespread antibiotic use.
Secondly, because Imidacloprid acts on the nAchR target, it has the defect of serious failure after multiple transmissions, causing a diminution of effect.
So currently, the efficacy of Imidacloprid has been shrinking, like a queen-bee stepping down to become a Madame.
In the field of nicotinic insecticides, Imidacloprid is classified as the first-generation nicotine insecticide, Thiamethoxam as the second generation, and Flonicamid as the third generation.
As for Imidacloprid in its domain, the current Imidacloprid is an optimized version of the third generation.
Exactly, just the third generation.
The Imidacloprid from the novice mission’s reward claims to be the fifth generation, implying that...
There’s an entire generational technical barrier between it and the existing Imidacloprid.
There’s a rule in pharmaceutical development, that there must be progressiveness between ’generations,’ and skipping generations is impossible.
Just like there’s a gap between button phones and foldable smartphones that requires intermediate smartphones with virtual keypads to fill in, without an intermediary product, the chasm between generations is almost insurmountable.
In other words.
For Xu Yun to turn the fifth-generation Imidacloprid into a producible new product, he must break through the fourth-generation technical barrier.
Then Xu Yun further unfolded the parchment, hoping to gain some inspiration.
"ClC1N=CC(=CC=1)CN2C....."
"Exact molecular weight 255.05200..."
Quickly, Xu Yun’s gaze locked onto a line in the Mol formula:
0.0000 N 0 0 0 0 0 0 0 0 0 0 0 0
10.1936 4.2021 0.0000 N 0 3 0 0 0 0 0 0 0 0 0 0
11.3603 3.1516 0.0000 O 0 0 0 0 0 0 0 0 0 0 0 0
10.5200 5.7378 0.0000 O 0 5 0 0 0 0 0 0 0 0 0 0
8.2153 2.2238 0.0000 C 0 0 0 0 0 0 0 0 0 0 0 0
6.6453 2.2238 0.0000 C 0 0 0 0 0 0 0 0 0 0 0 0 .
Meanwhile, a large set of information flashed quickly through his mind.
After about two minutes, Xu Yun slapped his forehead:
"My goodness, is it really this thing?"
....
Note:
Perhaps I didn’t explain clearly enough before, causing some friends to think that this book was doomed, and they helped summarize a bunch of issues.....
Um, actually, it’s like this, our book has always had good follow-up readings. By ’life or death day,’ I didn’t mean an ordinary recommendation, but rather the best new book opportunity, even better than Sanjiang, with only seven spots out of four to five hundred books per phase on the entire starting point.
Besides, today the results were announced, and I successfully advanced with the little trumpet, even among the top few. Thank you!
Lastly, regarding the mol formula, I got it from a friend who works in a drug research institute. Precise, isn’t it?
