But what's more funny is that Li Tian actually did a good job.
Such an alternative square dance naturally attracted the attention of many people, and it quickly became the handle of the entire square dance.
Many middle-aged and elderly women looked at Li Tian with admiration, and after Li Tian danced a dance, they asked Li Tian if he was married. They were high there and wanted to introduce their unmarried daughters to them. Li Tian, ​​to make good things.
However, Li Tian did not refuse either.
When he came back, he said to Zhou Ruihan: "Look, am I good?"
Zhou Ruihan was quite speechless about this, and rolled his eyes and said: "You can do it, you are great, your harem will soon be unable to live in a community."
Li Tian laughed, then said to Zhou Ruihan: "Go, let's go eat delicious food."
…
Li Tian is so happy, of course, because there is a voice in his mind. [Congratulations on completing the task, reward 200,000 yuan in cash, 2,000 draw points, and 2,000 system experience points. 】
After completing the task, Li Tian was of course happier, and then he went home with Zhou Ruihan.
Of course, Li Tian immediately removed all the glowing light sticks after getting in the car.
Zhou Ruihan couldn't help but smile when he saw this scene: "Why don't you keep it?"
Li Tian smiled and said, "Do you like it? If you like it, then I will keep it."
"..."
Zhou Ruihan didn't know what to say to such a shameless man.
…
But this time the two went straight home, and Li Tian personally made Zhou Ruihan a large table of delicious food, but Zhou Ruihan was moved to the point.
Of course, Li Tian's cooking skills are absent. Zhou Ruihan is delicious.
In the evening, adult men and women have a romantic evening.
…
After Zhou Ruihan fell asleep, Li Tian turned on his system.
[Current system level is 50, total experience value: 178651]
After using the good luck card, just click to confirm the draw.
[Congratulations to the lucky draw for winning a red envelope of 10,000 yuan in cash. 】
[Congratulations to the lucky draw for winning a red envelope of 10,000 yuan in cash. 】
[Congratulations to the lucky draw for winning 2 [Good Luck Cards]. 】
[Congratulations to the lucky draw for winning 2 [Dangerous Prediction Capsules]. 】
[Congratulations to the lucky draw for winning 4 [5 times a day card]. 】
[Congratulations on winning 2 [random special task cards] in the lucky draw. 】
[Congratulations to the lucky draw for winning 2 bottles of [Evolution Version Fast Forward Potion]. 】
[Congratulations to the lucky draw for obtaining 2 special items of level 50 [Golden Skill Card Fragments]. 】
【...】
What made Li Tian happy was not only the time doubling card, but also succeeded in allowing Li Tian to continuously obtain the ability to double time.
At the same time, what made Li Tian most happy was the golden skill card, because of this thing, Li Tian successfully obtained 11 pieces.
He did not hesitate, and immediately clicked to synthesize.
Then Li Tian really gained a new special ability.
[Congratulations on obtaining the perfect gene extraction skill. 】
Seeing this new skill, Li Tian's happiness is indescribable. Sure enough, what he needs, as long as he works hard, the system will give it.
In the newly built biological laboratory, Li Tian searched for medicinal materials from all over the world in order to treat Zhao Wan'er's disease. Among them, the three most important medicinal fossils are difficult to extract from current medicine.
But with this new skill, Li Tian obviously has a new method.
Genes (genetic factors) are all the nucleotide sequences required to produce a polypeptide chain or functional RNA.
Genes support the basic structure and performance of life. It stores all the information about the race, blood type, gestation, growth, apoptosis and other processes of life.
The interdependence of environment and genetics deduces important physiological processes such as the reproduction of life, cell division and protein synthesis. All life phenomena such as the birth, growth, decline, illness, old age, and death of organisms are related to genes. It is also an internal factor that determines life and health.
…
The DNA fragments with genetic information are called genes. Other DNA sequences, some directly function in their own structure, and some are involved in regulating the performance of genetic information.
At least 265 to 350 genes are required to form a simple life.
Li Tian has studied and studied these important information.
Genetic DNA is not only biological, but also plants.
Plant gene
Use artificial methods to extract exogenous gene fragments and carrier DNA from different organisms, cut, splice and recombine in vitro, and then adopt a certain method to introduce the recombined carrier DNA with exogenous genes into plant cells and make It is replicated and expressed in plant cells to achieve the expected purpose of changing the genetic characteristics of recipient plant cells. This process is called plant genetic engineering.
The above is the conventional method. If Li Tian wants to extract DNA from fossils, it is not so easy.
…
Li Tian rests with Zhou Ruihan here.
On the other side of him, in 24 hours, people had arrived in the medical laboratory.
All recruited here are top medical experts.
The most commonly used method for extracting DNA from fossils is the silica extraction method, which is based on the adsorption of DNA molecules on silica. By taking out a small amount of bone powder from the fossil and dissolving it in a specific solvent containing silica for centrifugation, the DNA in the bone powder will be adsorbed on the silica.
In addition, polymerase chain reaction (PCR) is also a commonly used method in ancient human DNA extraction, which uses DNA polymerase in cells to extract DNA fragments.
But neither of these two methods can perfectly resurrect medicinal fossils.
Li Tian put on a special sterile suit.
The fossils of medicinal materials thousands of years ago are extremely precious, and even the entire planet has only these. If Li Tian fails, it will undoubtedly be difficult for Zhao Wan'er to successfully cure Zhao Wan'er by relying on the records in "Shen Nong Medical Book".
…
When Li Tian is working, other experts can leave work early.
Because Li Tian will use the perfect gene extraction skill next, he is the first time to use this special high-tech skill.
After he used it, golden light appeared on his body, and then the light was attached to his fingers. Then, under a series of incredible operations, the fossil medicinal materials that had been stored for thousands of years were cut apart in this way.
Immediately afterwards, an aura of medicinal materials that seemed invisible to the naked eye was wrapped in golden light, and successfully merged with ancient DNA, and was finally refined.
Li Tian carefully placed it in the culture tank, and then carefully, even pouring a little fast-forward potion with his fingers trembling slightly.
Then ~EbookFREE.me~ a magical scene appeared.
That one, the magical medicinal material that existed in ancient times, was actually resurrected in this way.
Li Tian is not stingy, he is very excited.
Not only was Zhao Wan'er saved from her illness, but the sense of accomplishment of the resurrection of medicinal materials thousands of years ago is simply indescribable.
…
Then pour the fast-forward potion, the medicinal materials grow up magically, and Li Tian uses the hybrid breeding skills to successfully cultivate a dozen trees, and pour the fast-forward potion again.
call--
Li Tian finally breathed a sigh of relief, because at this moment he finally successfully resurrected a kind of medicinal material 10,000 years ago, and also cultivated more than a dozen plants at once. In the future, these dozens of plants will develop hundreds of thousands, millions .
