: )

Liu Wei smiled slightly and saw some blushing on the woman's waxy face, no need to guess, the villagers scolded him must be unbearable, making it difficult for a cultural person to speak.
"It's okay, I understand them!" Liu Wei finally smiled.
After the woman apologized, she returned to the crowd and told the villagers something.
Liu Wei did not give up.
He was full of curiosity about the mutated two-headed cobra venom.
Is it true that its venom can poison more than 20 adults or even an adult elephant, as reported by the fighting national media?
The average Indian cobra snake venom does not reach this level of severity.
There are two main types of species variation.
One is to adapt to changes in the environment without changing genetics.
There is also a genetic change. Gene mutation changes the species' morphology, physiological structure, cell structure, etc.
Liu Wei believes that the mutation of the double-headed cobra belongs to the latter. The genetic mutation not only changes the appearance of the two heads, but also changes its venom toxin.
He decided to stay and wait for a suitable time to take the venom of the two-headed eye snake and do a venom test.
Until the afternoon, the villagers found that Liu Wei had not left, and set up a tent in the open space not far from the courtyard.
But he didn't enter the yard anymore, and the villagers were not good at cursing him. Both sides closed their eyes.
Soon, a military green off-road vehicle drove to the door of the yard.
The door opened, and a white man came down first. His hair style and beard were similar to those of Lahal, whom Liu Wei met in the grassland.
Liu Wei was thinking, wouldn't it be another expert?
Many experts met along the way, it seems that wildlife conservation in India is not very easy to do!
After the white man got out of the car, two young men got off the car and followed him into the yard.
Liu Wei picked up the live room and laughed: "Brothers, there is a good show!"
He seemed to know the result of these people entering.
As expected, Liu Wei walked to the door, and the three people who entered were surrounded by the villagers again.
"Are these villagers crazy? Scold them when they see them!"
"What do you know? People are beliefs!"
"The power of faith is really terrible!"
Liu Wei smiled in the face of the live broadcast room: "Brothers, the villagers did not just see anyone so rude, but they met people like us, because we would have to experiment with their master god!"
"Awei, did the people inside come for the two-headed cobra?"
Liu Wei said with a smile: "Otherwise! Look at their dress and car, what else are they worth coming from?
I guess it might be another expert!"
The audience laughed: "There are so many experts in India!"
Liu Wei stood outside and watched the play.
The white man came out within ten minutes.
The young man behind the white man was a little angry and scolded: "Ignorant, stupid!".
The white man said: "Don't complain, respect local customs, but a good research object!"
Liu Wei took the live room and leaned on the off-road vehicle and turned back and smiled at the white man: "Maybe we can cooperate!"
The white man walked to Liu Wei, curiously: "Are you?"
"This is my business card!" Liu Wei took out his business card and smiled, "I am just like you, just chased out!"
After watching the white man, he reached out and said, "Hello, Liu Wei, my name is Dennis, an Indian snakeworm research expert!"
Liu Wei couldn't help but smiled, as he was an expert, the two shook hands.
"Are you also here for the two-headed cobra?" Dennis asked.
Liu Wei: "Let's talk somewhere else!"
Dennis followed Liu Wei's tent, and the two young men who followed him drove the car to a hidden location.
Liu Wei sat down and said, "My teacher is a famous Chinese snake snake research expert. I passed by and heard that there are two-headed cobras.
Dennis said helplessly, "Hey, we are here for the third time. The two-headed cobra has always been the object I want to study, but you know, the villagers regard it as the main god, and I can't do anything about it.
The local government also came forward to help us. They are always reluctant to hand it over, but I don’t want to give up. The survival time of this mutant snake in the wild will be very short. If we want to extend its lifespan, we must pass our rescue!"
Liu Wei patted Dennis on the shoulder, indicating that the two were empathizing at this time. Liu Wei asked curiously, "Is there a double-headed cobra snake venom specimen in India? Can it really poison the elephant?"
Dennis shook his head, "No, now our research on the two-headed cobra is still in the blank stage!"
Liu Wei smiled: "It's coming, we will soon know how toxic it is!"
Dennis is not only studying the snake venom of the two-headed cobra, but now he cannot persuade the villagers to hand over the snake. If he can measure its toxicity, it can be regarded as a zero breakthrough.
Thinking of this, he opened his eyes and pondered Liu Wei's words carefully. He felt that Liu Wei had to take action and asked, "What are you going to do?"
Liu Weidao: "You look at the surrounding environment, except farmland, there is no suitable environment for cobra activities. I have seen the double-headed cobra today. It now looks very dependent on the food given by the villagers, so it will not run too far. The dark place around the yard is its best choice for concealment.
We have all been kicked out once, and the villagers must be suspicious. When they go out to work in the afternoon, and when the temperature has just dropped, we will go to the crack in the wall around the yard. At that time, the two-headed cobra should come out and be active. .
It is impossible to take away the snake, but there is still time to take away its venom while they are not paying attention!"
Dennis suddenly realized, "How can I help you?"
Liu Weidao: "Although the two-headed cobras share the same body, they have separate heads, eyes, mouth and fangs. I and you take the poison at the same time!"
"Try it!" Dennis couldn't wait to study this mutant viper, and reached a cooperation agreement with Liu Wei.
When the sun is about to go down, the villagers will go out to work for the last time.
When they walked in front of Liu Wei and Dennis, their eyes were a little bad, and Liu Wei still responded with a smile.
Seeing that there were only a few children playing in the yard, and every family was busy making dinner, Liu Wei called Dennis to set off.
"Brothers, we need quick battles and quick decisions, so we won't take you with you, we will show you the drug testing scene in a moment!" Liu Wei whispered.
"Ojbk!"
"Gkd, Awei!"
The audience is also urging Liu Wei.
Liu Wei and Dennis held their hands empty and took the poison cups in their pockets, wandering around like an idle man.
Walking along the border between the yard and the farmland, Liu Wei was really hit.
The two-headed cobra drilled out of the crack.
Its body is relatively small, and Liu Wei controlled it easily.
He and Dennis glanced at each other, and the two began to take drugs.
The two-headed cobra bite the two poisoning cups respectively, and the poison gland drops two drops of venom.
Liu Wei observed, "The amount of detoxification is very small, it's gone!"
Dennis speculated: "It may be related to its body size!"
"Okay, let go!" Liu Wei let go of his hand and just came out and met the villagers again. The villagers' eyes glanced at them.
Liu Wei smiled and waved his hand, and Dennis accelerated his pace and returned to the camp.
"Is there any experimental equipment in the car?" Liu Wei asked.
Dennis nodded: "Some simple equipment!"
"Try it!" Liu Wei said.
Dennis nodded.
Driven the car, took out a cage of small white mice from the trunk, about 40 or 50 mice, as well as some injection tools and professional lab coats.
Liu Wei gave Dennis the snake venom he had taken out directly, "Come on! I will broadcast live and tell the audience to test the snake venom!"
The two young men brought by Dennis set up a simple workbench. Dennis put on his lab coat and began to operate.
Liu Wei explained while shooting: "Brothers, I have given you the science of snake venom test before. I compared the ld50 value, that is, the value of the half-lethal amount. The lower the value, the stronger the toxicity.
First, Dennis needed to dilute the snake venom to different concentrations and inject it into the mice.
The four indicators of LD50 are 24 hours, 48 ​​hours, 72 hours and 96 hours, so this is a long experiment.
Count the number of deaths of mice in each period of time, and then use the mathematical formula of the half-lethal amount, the mass of toxic substances/the weight of the experimental organism, and finally get the toxicity of the venom.
Since there is no special equipment to protect the venom we removed, in order to allow the venom to be used before it deteriorates, we are now doing this experiment on site.
It may be a bit rough, but if it is started by a professional snake animal research expert like Dennis, the error should be extremely small!"
Dennis listened to Liu Wei’s speech and interjected,
I’ve done tens of thousands of experiments on snake venom, and I guarantee that today’s experiment will not fail!

Liu Wei nodded, "I believe in your professionalism!"
The young man who followed Dennis was busy recording relevant data, but Liu Wei was relaxed, and it was okay to pour the dog. He only had one final answer, that is, what is the ld50 value of this two-headed cobra snake venom?
...
After measuring all the indicators, Dennis finally gave the data at 0.0025mg/kg.
When he heard this value, Liu Wei was surprised for a moment.
"What's the situation? Awei!"
"what's the result?"
"Can the elephant be poisoned?"
The audience waited for such a long time, and could not wait to get a result from Liu Wei's mouth.
Liu Wei returned to the Shinto: "Brothers, our previous suspicions have not been confirmed. The ld50 value of the double-headed cobra venom is 0.0025mg/kg, second only to the world's most poisonous snake, the Australian outback Taipan snake, and its ld50 value is 0.0021mg/kg, so there is a high probability that the Russian media reported that the double-headed cobra could poison the adult elephant!"
"Dream trough, is it so good?"
"Subvert my worldview!"
"Don't touch the mutated thing, let it continue to be the main in the hearts of the villagers!"
"This of death! Return the god!"
A variety of amazing emoticons are scrolling on the screen of the live broadcast room.
Dennis pulled Liu Wei's body, "Come and see the dead mouse in the experiment, there are new discoveries!"
