Homo sapiens

Chapter 13 Cost
On the premise that money opened the way, Li Jinglan soon purchased a large number of mature or semi-mature eels in the coastal areas of southern Fujian province.

These eels are then transported to Caragua Island by a special live seafood carrier.

at the same time.

Li Qingye also received another message.

Through the satellite phone, Kang Nan, who went out to fish for eel fry, reported to him an important piece of information, that is, the number of glass eels has become extremely rare in the wild eel breeding waters near the Luzon Trench.

According to the communication between Kang Nan and more than a dozen colleagues, the number of glass eels at this time is only a few tenths of previous years.

Many fishing boats have been busy for a few weeks, and they have caught dozens of catties of fish fry. In previous years, they could catch several tons of fish fry, which is a cliff-like decline.

Li Qingye naturally understands that this is the beginning of the evil results of overfishing, and at the same time, this is also an opportunity and a huge outlet.

In the case of scarce wild resources, the price of fry will be raised rapidly, and at the same time, capital investment will be stimulated.

Now he must quickly develop low-cost eel breeding technology before other companies develop similar technologies.

At present, the most in-depth research institution on the artificial reproduction of eels is a research institute from Japan. They have already realized the artificial reproduction of eels, but the production cost is too touching.

The technology developed by Dongying Research Institute is to promote mature eels to enter the reproductive state through hormone stimulation and environmental regulation.

The current production cost of a captive-bred eel is $6.

The wholesale price of wild eel fry ranges from US$5000 to US$7000 for 12000 glass eels.

The price difference between the two is too large, and artificial eel fry are not competitive at all.

Li Qingye had read the relevant papers of that research institute, and even used hacking methods to turn the other party's network upside down.

Although the research institute concealed some key data, it has recently lowered the production cost to around US$1 apiece.

But Li Qingye is not optimistic about them, because the key to this set of artificial reproduction technology lies in special hormones, and the cost of those special hormones lies there.

Using data from Japanese researchers, he deduced a whole set of technologies.

"The key lies in the eel's special sex hormone. At present, this hormone cannot be synthesized artificially, and several alternative hormones are not cheap, and it is easy to cause abnormal development of the eel." Li Qingye cleared his mind.

Soon he was experimenting.

First, through the joint action of various hormones and the stimulation of simulated environmental pressure, the eels are promoted to enter a state of sexual maturity.

So I found that special eel sex hormone and extracted it.

Comparing the gene sequences before and after sexual maturity of eels, some gene sequences that may be related to sexual maturity were found.

The next step is very simple, that is to use the CRISPR sequence and the building wood factor to inactivate some eel genes.

After more than a month of research, he quickly locked the gene sequence of the eel's sexual maturity, cut out these genes, and inserted them into the yeast through CRISPR-Cas9.

Soon under environmental stress, the genetically recombined yeast rapidly produced eel sex hormones.

In addition to equipment, the production cost of this hormone has dropped significantly, about 5 US dollars per gram.

This is still the production cost of the laboratory solution. If the industrialized production solution is adopted, the production cost will continue to decrease.

With this particular eel sex hormone, he quickly injected the mature eels.

In the C5 area of ​​the experimental base.

More than a dozen employees responsible for checking the eel breeding tanks took a pen to record the situation of each tank.

Li Qingye and Li Jinglan looked at the situation in each tank.

"Has it succeeded?" Li Jinglan was very excited, looking at the glass eel in the water tank, as if seeing gold swimming.

Li Qingye said calmly: "Well, the technology has matured. Two mature eels can produce 100 to 300 million eggs. Without the interference of other predators, 30% of these eggs can develop into glass eels."

"Boss, we have developed. In January this year, the price of a piece of eel fry has reached 3 dollars, and there is no stock yet."

Li Qingye ordered: "You take people to Huaguo, Dongying and Southeast Asia as soon as possible, and sell the eel fry we have in small batches, but don't expose that we have artificial breeding technology."

"Work hard, the company will give you bonus shares in the future, and let Kangnan come back! You don't need to fish fry anymore, he will follow you first."

"Understood, I will do a good job." Li Jinglan smiled all over his face.

Looking at Li Jinglan who left in a hurry, Li Qingye's expression was very calm, but there was something meaningful in his eyes.

Betrayal is human nature.

His father believed in the so-called faith too much, and was backstabbed again and again by his like-minded partners, and finally his family was ruined.

'Instead of believing in beliefs, it is better to implement means, father, I am not naive, and I am not qualified to be naive. '

Li Qingye thought silently with his hands in his pockets, the white coat on his body was white and cold, and he walked towards the direction marked with Area A.

The entire scientific research base is divided into four levels of areas A, B, C, and D. Among them, there are two types of areas AB, and only Li Qingye has permission to enter.

Although he has been researching eel breeding technology for more than a month, in fact, this is just one of the small projects.

How difficult it is to survive in this cruel world and to be an upright person.

Without strength, Homo sapiens cannot be defended.

If you don't want to be a dog for people, you can only kill those guys who want to train dogs.

At the same time as he was researching eel reproduction technology, he started a research project on biological weapons.

Enter the most core area A.

Looking at the orange liquid in the glass reagent bottle, there are some cells that are difficult to detect with the naked eye floating in it. This is a malaria parasite modified by genetic recombination technology, a microorganism that can cause malaria.

Li Qingye has carried out a comprehensive transformation of it.

First, it improves its drug tolerance, and none of the antimalarial drugs on the market can work on it;

Second, the ability to reproduce is knocked out so that malaria parasites cannot reproduce naturally.

Third, the dormant gene sequence of tardigrades was inserted, allowing it to have a latent period of about 7 years.

Fourth, the abnormal gene sequence of insects is inserted. Once activated by special pheromones, they will wake up from dormancy and start to run wild and destroy.

Fifth, the cell symbiosis mode, which is to ensure that the malaria parasite will not be digested and decomposed by the human body during the dormant period, and the cells that Li Qingye chooses to let them parasitize are human brain cells.

At present [Gu insect type 1 - malaria parasite] has completed the preliminary modulation.

But Li Qingye still feels that it is not perfect, because [Gu worm - malaria parasite type 1] still has some shortcomings.

For example, it can only be injected through a syringe, which is too obvious. How he tricks others into injecting is a problem.

Another problem is that the special pheromones that need to be used in the activation process also need to be injected, which increases the uncontrollable factors.

Now he has to find a way to solve these two problems.

And this type of external trigger, if you are prepared, you can wear protective clothing to isolate the trigger of pheromone.

From now on, it seems that there is some truth to the three-corpse brain pill that is triggered internally periodically.
