Chapter 180 Everything is really engraved into DNA now (6.241K)
outside world.
As the drizzle fell.
Many events that would have developed in another direction have quietly turned a corner.
These things may be big or small, light or heavy.
Among them are plans at the national strategic level, small businesses of ordinary people, and trivial quarrels among ordinary people in the market.
The drizzle was like a broom.
It swept away all the violent garbage in society, and silently changed the life trajectories of countless people.
And when these countless inflection points of quantitative change are accumulated together, certain qualitative changes will naturally occur.
Of course.
This qualitative change cannot be seen with the naked eye or touched, and it may take a long, long time to actually see results.
From those in power to ordinary people, at most they feel that many things seem to be going more smoothly than expected, and that's all.
Therefore, Xu Yun, who was in a claustrophobic space, naturally had no way of knowing these changes.
He could only guess from the literal meaning that this was probably a blessing-like buff, which was also a common effect in the game.
But he didn't understand the effect of this so-called +1.
Then he put his curiosity aside for the moment and returned his attention to the ball.
He had knocked away four balls before.
A time album, a formula card without any explanation, an easter egg and a buff were released respectively.
Although these rewards have their own characteristics, their value is not low.
But none of them seem to be realistic technologies similar to imidacloprid formulations.
I wonder if there will be some other black technology in the next four balls?
Think of this.
Xu Yun couldn't help but stretched out his hand and poked the fifth bubble.
Bo~
After a while.
A piece of paper floated in front of Xu Yun again.
He subconsciously took the piece of paper.
The texture of this piece of paper is very soft, only the size of a band-aid, and the content on it is also very concise, with only one landmark written on it:
Longitude:117.2764
Latitude:31.8392
[Hint: This is a coordinate. Guess what you will find? 】
Xu Yun suddenly frowned.
Although his major is science, it has nothing to do with geography, and he has not had much contact with longitude and latitude information in his spare time.
But as a HKUST person for two lifetimes, he still has some impressions of this number:
Ignore the last few digits, just look at the first five digits. Isn’t this the HKUST campus?
It's hard to say where the last three digits are, but they must be on the HKUST campus.
On the HKUST campus. What will be there?
There can't be any more cockroaches, right?
Moreover
What should I do if it’s a girls’ dormitory?
With this somewhat subtle mood, Xu Yun put the piece of paper away and continued to click on the sixth ball of light.
Bo~
The moment he saw the evolution of the light ball, his brows raised slightly:
The sixth ball of light was still a small piece of paper, but this piece of paper was somewhat familiar to him:
The paper originally engraved with the fifth-generation imidacloprid formula was made of this material and specifications.
Sure enough.
When the piece of paper falls into your hand.
Xu Yun spread it flat in the palm of his hand and saw a line of words written on it:
[DNA storage technology: This is a very interesting technology, but it also requires hundreds of millions of efforts to research. Are you ready, boy? 】
[Evaluation: Don’t engrave everything into your DNA, except Fenghualian’s out-of-print video before she retired. 】
"Hey guys, DNA storage technology?"
As a biological scientist, Xu Yun has been relatively familiar with cutting-edge biological technologies in his life.
in the current cutting-edge field of biology.
DNA storage technology has always been a project that is not widely spread but is recognized as very promising.
The theoretical basis of this technology is simple:
first.
Current computer data is stored in 0s and 1s, which is binary.
And all the students who haven't been mad at the biology teacher should know this.
Each bit of DNA has only four possibilities:
AGCT.
If the bases are assigned values, such as A+T=0, G+C=1, then the chemical signal can be converted into a digital signal.
Therefore, a DNA can be regarded as a binary data storage material.
As for why DNA is used as data storage material?
The reason is also very simple.
The amount of information produced by the earth every day now far exceeds the total amount of information produced in the past 5,000 years of human civilization evolution (Source: International Data Corporation).
This is also the origin of the term big data era.
Estimated based on current trends.
Within next year alone, 48ZB (1ZB=10^12GB) of data will be generated.
Wait until 2040.
The world needs at least one million tons of silicon-based chips to store the data generated that year.
So, someone took aim at DNA.
Technically speaking.
In addition to binary effects, DNA can be artificially synthesized from scratch, which can be achieved with a solid-phase synthesizer.
In addition, DNA can be amplified in large quantities in the laboratory through PCR technology.
This ensures that large amounts of DNA with desired sequences can be synthesized easily.
As for the advantages of DNA for information storage
Naturally, it has high storage density, low energy consumption, long storage cycle, etc.
For example, the storage density of DNA can reach 10^19bit/cm3, which means that in theory, only one kilogram of DNA is needed to store the current total amount of global information.
In 2012.
Church and others from the University of Pennsylvania used DNA synthesis technology to store a book, including 53,426 words, 11 pictures and a JavaScript program, totaling 5.27MB.
Subsequently, they stored an animated gif information into DNA and introduced it into E. coli to replicate itself.
By last year, that is, 2021.
A local team from Southeast University successfully stored the four Chinese characters of the school motto "Ending with Perfection" into a DNA sequence. This matter was also featured on SCIENCE ADVANCES. (DOI:10.1126/sciadv.abk0100)
But on the other hand.
Although this technology is promising, it also has great limitations.
The first is cost.
Generally speaking.
The DNA base AGCT costs 0.5-1 US dollars each, which is 3-6 Chinese coins.
Because the "consumables" are too expensive, it is difficult to conduct experiments and popularize them for civilian use.
The second is the problem of reading.
Currently, it takes several months on average to store a movie, which is much longer than the computer hardware cycle.
At the forefront of the entire technology right now is a team led by Erlich of Yale University. Not long ago they coded an operating system called movie1.
Not only can this system run smoothly, it can even play minesweeper.
all in all.
This is not a technology that appears out of thin air. It has a certain foundation and possibility of finished products, and its acceptance is relatively not that difficult.
But it's predictable.
Just like the original fifth-generation imidacloprid formula, there was also a fourth-generation threshold.
The DNA storage technology provided by Halo probably still requires a lot of effort in research and development to achieve results.
At the same time,
There was also an indescribable emotion in Xu Yun's heart.
He always felt that this technology seemed to be prepared for other things.
But after much thought, he finally couldn't figure out what it had to do with, so he could only put the idea aside for the time being.
Maybe it’s just my own random thoughts
Anyway no matter what.
This DNA storage technology is also the only physical technology he has obtained so far.
The previous equations and landmarks were at most only possible with certain technical implementations, and could not be regarded as guaranteed formulas.
Xu Yun then adjusted his breathing and cast his gaze on the last two light balls.
What will appear in them?
soon.
Bo~
This time.
What appeared in front of Xu Yun was still a piece of paper with the same DNA storage technology.
Technical reward two hits.JPG.
After getting the piece of paper.
Xu Yun skillfully turned over the piece of paper. When he saw the information written on it, he was slightly stunned:
"Good guy, why is this thing?"
I saw a few words written on the piece of paper:
[Artificial Intelligence-Entry Edition-Upgradeable]
[Evaluation: It is an artificial retard that is much dumber than Xiao Ai’s classmates, but as long as you can become a long-distance runner, you may see it upgraded one day! 】
Xu Yun:
"."
Tell the truth.
After two missions, he already had some understanding of Halo's personality, or was somewhat prepared.
Therefore, what silenced him was not the saucy words spoken by Halo, but the nature of the reward:
The technological rewards that emerged this time can be attributed to physics, computers, and even mathematics.
But it is the only one that has little contact with living things.
So does this explain one thing:
Are the rewards given by the halo more than just technology or knowledge in the biological field?
If that's the case.
The actual value and influence that the halo may have are much higher than Xu Yun's original expectations.
After all, from the perspective of life research, biology and chemistry are definitely key subjects.
But from a technological perspective, physics and mathematics are the real core subjects.
It would be interesting if Halo's rewards included other rewards.
To know.
Lao Su's mission was only a four-star mission.
Not to mention there is a comparison link to complete the scoring.
If you achieve a high score ratio in a five-star mission, what will be the reward?
Controlled nuclear fusion?
Anti-gravity technology?
Or an automatic coding keyboard?
Endless possibilities
With such a comparison, the artificial intelligence retardation reward itself is not so eye-catching.
After all, the entry version and subsequent reviews can speak for themselves.
If you want this thing to be upgraded, I'm afraid you still need to complete a few more tasks.
From the perspective of capability realization, its ranking may be even lower than DNA storage technology.
Of course.
Consider the four words artificial intelligence in the official name.
The value of this reward after it is realized is obviously far beyond what DNA storage technology can match. From a value perspective, it is worthy of its penultimate ranking of light balls.
When talking about the penultimate one, we have to mention the penultimate one - or the only ball of light left.
Then Xu Yun took a deep breath and put away the small piece of paper,
He looked at the eighth ball of light.
I don’t know if it’s because of my mentality.
He always felt that this ball of light seemed to be a little larger than the other seven, similar to an egg or a goose egg.
Then he was silent for a moment and stretched out his finger towards the final ball of light.
Snap——
The eighth ball of light emitted a distinctive broken syllable.
After a while.
A golden particle beam slowly floated out of the light ball.
This particle beam neither flies towards the halo like a space-time album, nor does it appear as a piece of paper or a golden egg like other rewards, but
It slowly flew around in space, and finally disappeared suddenly.
Xu Yun:
"????"
Could it be another buff similar to the Great Cauldron?
That's not right.
Although the great cauldron of the previous national destiny finally disappeared from the space, there was still some explanation before it disappeared.
From a performance perspective
It seems that the shortcomings of national sports rewards and formula cards are combined?
Scratching the head.JPG.
Think of this.
Xu Yun couldn't help but sigh slightly:
The eight light balls were all dismantled at the moment.
Among them, national luck, formula cards, and golden particle beams are all unclear things, and it is difficult to see where they are coming from and where they are going.
Artificial intelligence is an entry-level retarded one, and there shouldn’t be much hope in the short term.
As for the Easter eggs.
This stuff may bring emotional surprises, but it won't have much practical value.
While it is still unknown what he will find at the coordinates of HKUST, the rewards that really make Xu Yun feel "not a loss" are actually two kinds:
Space-time photo album and DNA storage technology, the former is the first reward to be unveiled.
Isn't this a stretch of the crotch? Is it worthy of what I have worked so hard for?
If this content were included in the novel I wrote in my previous life, I'm afraid I would be criticized by readers!
Think of this.
Xu Yun looked around again.
The rewards that should be obtained now have been taken, and the time-consuming time of the space-time photo album has been used up. There is no point in staying in space.
So he thought for a moment and decisively chose to return to reality.
Swish——
After a slight dizziness passed.
Xu Yun's eyes lit up and he returned to the long-lost cabin. He was standing in front of the computer desk.
As soon as you turn on the phone, the time will appear automatically.
Same as the 1665 copy.
Nearly a year has passed in the copy, but only a few seconds have passed in reality.
Wear a down jacket and warm boots when walking.
When he returned, he was dressed in ancient clothes, and even his hair was grown to look like an ancient person.
At the same time.
Xu Yun was also surprised to discover something:
After living in the Northern Song Dynasty for a year, he actually had a subtle but obvious sense of separation from reality, that is, the modern technological environment of the 21st century.
For example, the cell phone on the table.
When he first turned on the phone to check the time, he pressed the volume button several times before realizing that the small button below the volume button was the power button.
To know.
This is just the second copy he has ever experienced.
Who knows whether there will be a two-, three- or even five-year mission in the next mission?
This sense of fragmentation brought about by the switch between the two eras does take a lot of time to get used to again.
To use an idiom to describe it is.
It's like a lifetime ago.
Maybe next time you can prepare a memo on your desk before entering the dungeon?
Looking through the memo when you come back may help you recall the real things faster and avoid some psychological problems.
When he was writing novels in his previous life, he read a book called "Global Movie King". The protagonist in it seemed to have some psychological problems because of this.
For example, dressing up as an old man and falling in love with an aunt or something.
Thinking of this, a poem came to Xu Yun's mind:
"Who will wake up first from the big dream?"
However, just when he was still in a daze, a voice suddenly came from his ears:
"Where is this?"
"???????"
Hear a word.
Xu Yun's whole body suddenly trembled, and he turned around subconsciously.
I only see this moment.
Not far from him, standing at the end of the bed, was a young man in his 20s!
A series of possibilities including a thief flashed through Xu Yun's mind, and he subconsciously picked up an apple knife on the table.
With his shoulders lowered, he assumed the starting position of "Laifu Sword Jue" and shouted:
"Who are you?"
"Me?"
A puzzled expression appeared on the young man's face, and he stared at Xu Yun for a while with a frown.
After confirming that Xu Yun's expression was serious, he said in modern Chinese with a clear accent:
"I'm Su Song, what's the matter, Xiao Wang, you don't recognize me?"
At the same time.
A curtain of light slowly appeared in front of Xu Yun:
[Special mission settlement reward: 22-year-old Su Song, with complete documents, in his prime, with all the memories of his past life, be sure to give him a five-star praise! 】
[Evaluation: Su Song's reputation in history was not prominent for various reasons. Rather than correcting people's perceptions, it is better to let him create history again! 】
"What the hell?!"
Note:
After finishing this chapter, I feel relieved.
I feel like it was a little early to ask everyone to rate the day before yesterday. Many readers said that I deducted points for making Lao Su die in depression, but Lao Su’s ending is here
In fact, I had hinted that Old Su would come to modern times very early, and I hinted it more than once. The first was Xu Yun's admiration when he figured out the principle of the generator, and there were many similar hints later.
And he also said during the coup that unless Lao Su could truly see the original historical facts, he would not be able to let go.
This is also the foreshadowing I laid down from the beginning. Why did the protagonist travel to an adult Su?
How much change can a dying person make in the world?
The answer is here.
No matter what the dungeon history is, very few people know about Lao Su in local history. Of course, he has to change all this by himself...(End of Chapter)
