Chapter 43 The fourth generation that must break through
In a claustrophobic space.
Looking at the three objects in front of him, Xu Yun's expression was a little subtle.
Putting aside the Easter eggs, it is not difficult to tell from the description that this should be something that needs to be triggered in combination with certain real-life situations. There are currently no clues to judge.
Even in Xu Yun's view, considering his 80% critical hit rate not long ago, when Barbarian hit 5 times with 0 critical hits, it is not certain whether he will have a chance to activate the easter egg in this life
Everyone understands the pain of African chiefs.
After putting the easter eggs aside for now, only two items were left.
The first is Mavericks’ thinking experience card.
How do you say this?
There is no doubt that it is a good thing!
As the founder of modern physics, Maverick's intelligence is undoubtedly a peak in human history. To be conservative, he is definitely in the top ten.
Especially the Mavericks who were 22 years old in 1665. Probably no one in history can compete with him.
Therefore, there is no doubt about the quality of this thinking card. The only thing to worry about is its usage time.
In half an hour, Brother Dong can fight 15 times. However, in terms of problem-solving, half an hour can not only do less, but it can also say more.
Especially when facing some difficult problems, two or three hours is often the norm. Even in some mathematics forums, it takes four or five hours to solve a problem as a basic exercise.
Therefore, once this thinking card is used, it must be used on the blade, and timing is the most critical.
Xu Yun then moved his eyes to the piece of kraft paper, which was the reward recording the so-called fifth-generation imidacloprid formula.
Considering that there were no desks and pens in the space, it was not suitable for research calculations, so Xu Yun thought for a while and silently said "Return" in his heart.
Swish——
The space disappeared in an instant, and his consciousness returned to his hut.
After regaining consciousness, Xu Yun did not rush to summon the imidacloprid formula, but lowered his head and read it first
own feet.
At this moment, his feet were bare, without shoes or socks.
That's right.
Neither the original Anta shoes nor the brogues given to me by Mavericks came back with me.
Seeing this, Xu Yun couldn't help but touch his chin:
"In other words, the things on my body that meet the conditions will travel with me to the dungeon, but the things in the dungeon cannot be brought back?"
Then he thought of something and looked at his ankle again:
When he went to William's house for the first time, Mavericks took him to chop firewood once. At that time, Xu Yun's left ankle joint developed a red and swollen mass, which did not subside in the following days. Instead, a piece of broken skin formed.
But at this moment, the skin of Xu Yun's left ankle was smooth, with no trace of any break or squeeze.
In addition, in the past two weeks or so, due to the living standards in the 17th century, Xu Yun's body smelled more or less strange, and his clothes were not very clean.
But at this moment, these smells have long disappeared.
Xu Yun looked at the alarm clock on the table again. Four twenty-seven in the afternoon was exactly the same as when he entered the space.
"That is to say."
"My soul traveled to the seventeenth century, but the things I carried with me when I traveled will selectively appear in the dungeon?"
"For example, things like glasses, clothes and shoes that are modern but have technology that existed at that time will travel with me, while mobile phones and headphones will be automatically blocked?"
Xu Yun touched his chin thoughtfully. With such a comparison, the mapping relationship between the copy and reality became much clearer.
It's a pity that I didn't think enough about it before and didn't try to get a haircut at Maverick's house to see if my hair style would change after I came back.
Then he came to the desk, stretched out his hand, and concentrated his attention on sensing.
Phew——
The next second, a piece of brown paper gently fell on his hand.
There are a bunch of dense chemical symbols and Chinese characters written on the kraft paper. Some of the chemical structures make people feel dizzy at a glance.
However, as a Ph.D. in biology who was about to receive his degree, Xu Yun easily understood part of the chemical structure at the beginning.
C9H10ClN5O2, which is 1-(6-chloropyridin-3-ylmethyl)-N-nitroimidazolidin-2-ylamine, scientific name.
Imidacloprid.
It is a nitromethylene systemic pesticide, a chlorinated nicotinyl pesticide, also known as a neonicotinoid pesticide. It was formally proposed at the 1991 Brighton Crop Protection Conference in the UK. superior.
It is an agent of nicotinic acetylcholine receptors, which interferes with the motor nervous system of pests and causes the failure of chemical signal transmission. It is mainly used to control piercing-sucking mouthpart pests and their resistant strains.
In agriculture, it is mainly used for the control of aphids and plant lice, but its biggest use in life is to kill various furniture pests.
Since its launch in 1991, it has been rapidly promoted and has spread to more than 40 countries around the world in just three years.
Today, it can be said that if there is a plant protection department, there is imidacloprid. Currently, imidacloprid has become the world's number one insecticide, and its global sales in 2014 have reached 1.14 billion US dollars.
However, for such a product that has come to the forefront, life has not been easy in recent years.
The first is the problem of pest resistance caused by long-term use. With the widespread use of imidacloprid, a large number of greenhouse pests have become resistant to imidacloprid - just like antibiotics, it is an inevitable result of widespread use.
Secondly, because the target of imidacloprid is nAchR, it has a defect that it will be seriously ineffective after multiple rounds of delivery, resulting in diminishing effects.
Therefore, the effect of imidacloprid has become less and less effective at present, as if the oiran is getting older step by step, and finally becomes a madam.
Among nicotine pesticides, imidacloprid is the first generation nicotine pesticide, thiamethoxam is the second generation nicotine pesticide, and dinotefuran is the third generation.
However, in the single field of imidacloprid, the current imidacloprid is an optimized product of the third generation.
That's right, it's just the third generation.
The imidacloprid obtained as a reward for the novice mission is called the fifth generation, which means
There is still a whole generation of technical barriers between it and the existing imidacloprid.
There is a rule in drug research and development, that is, there must be progress between "generations", and there cannot be a leap across generations.
Just like smartphones with virtual buttons between button phones and folding screen phones, without a relay product, the gap between generations is almost difficult to bridge.
In other words.
If Xu Yun wants to turn fifth-generation imidacloprid into a new product that can be put into production, he must break through the fourth-generation technical barrier.
Xu Yun then spread the kraft paper further, hoping to see if he could get some inspiration.
"ClC1N=CC(=CC=1)CN2C"
"Exact molecular weight 255.05200"
Soon, Xu Yun’s eyes locked on a column of Mol style:
700.0000N000000000000
10.19364.20210.0000N030000000000
11.36033.15160.0000O000000000000
10.52005.73780.0000O050000000000
8.21532.22380.0000C000000000000
6.64532.22380.0000C000000000000.
At the same time, a large list of information flashed through his mind quickly.
After about two minutes, Xu Yun slapped his forehead:
"Good guy, is it actually this thing?" (End of Chapter)
