The American alligator blinked twice, and opened its big mouth again to face Liu Wei.

Liu Wei stretched the mobile phone stand to shoot the crocodile's big mouth, the crocodile was about to move, showing restlessness, and it could bite down at any time.

"In the life of the American alligator, there are about two or three thousand teeth, and I remember saying when I was in the swamp crocodile, crocodile teeth are alloter teeth, which are easy to fall out and grow quickly.

By constantly changing teeth to match a strong bite force, it is used to catch large prey, and in actual combat, the American alligator has hunted and killed jaguars and black bears, and is considered the top predator in North America!"

Liu Wei went on to popularize science, "I also told you that crocodiles have built an excellent immune system through hundreds of millions of years of evolution.

Today, I will borrow the American alligator to give you a detailed science popularization.

Needless to say, the American alligator has an enviable innate immune system, which is the first primitive line of defense in the defense system that all vertebrates possess.

In 2008, chemists in Louisiana found that serum extracted from reptiles destroyed 23 strains of bacteria and dramatically reduced HIV populations.

These bacterial molecules are identified as enzymes that can destroy a class of lipids.

Chemists hope to turn the enzyme into new antibiotics that can be used to treat diseases such as AIDS.

In the body of the American alligator, enzymes are not the only defense weapon it has capable of destroying pathogens.

The Bishop team has identified and isolated polypeptides known as electropositive antimicrobial peptides, which are positively charged, allowing scientists to develop nanoparticles that use electrostatic electricity to pick these molecules out of a complex protein mixture of alligator serum.

Scientists found a total of 45 peptides, of which 8 were chemically synthesized and evaluated their antimicrobial properties, five peptides could kill some E. coli, the other three destroyed most of E. coli, and showed some activity against bacteria such as Pseudomonas aeruginosa and Staphylococcus aureus!"

"It means that I am listening to the book of heaven!"

"I feel so uneducated!"

"What's going on? Now you need knowledge to watch live broadcasts?"

"Don't use other live broadcast rooms, this live broadcast room really can't work!"

"Since watching Ah Wei's live broadcast, I seem to feel that my bragging skills are a lot more advanced!"

Liu Wei looked at the barrage of the audience, shook his head and smiled, "To put it simply, Pseudomonas aeruginosa is one of the common conditionally pathogenic bacteria in clinical practice, which is widely distributed in the skin, intestines, respiratory tract and even urethra of the human body.

The alligator serum has the ability to kill Pseudomonas aeruginosa in its complex proteins.

Therefore, intestinal diseases, skin diseases, etc., which are produced in the human body, do not appear in the body of alligators.

We know that crocodiles' living environment and food supply are far less clean than those of us humans, but under normal circumstances, wild American alligators have a lifespan similar to that of humans, and farmed alligators will be longer.

You can feel the strength of the alligator's immune system now!"

"Awesome, drink crocodile blood and live forever!"

"There are really Taoist priests in history who say that crocodile blood is alchemy!"

"Wake up, wake up, it's the 21st century, it's still alchemy, it's still immortal, it's too much fantasy!"

Liu Wei stretched out his hand and rubbed the forehead of the American alligator, "I'm sorry, I just made you suffer, in fact, my friend O'Neill likes you, but there is a mental obstacle between you that cannot be overcome."

He is afraid of you, and his actions are rude, and you have never expressed your tenderness, and I may be the only one in this world who can understand you!"

The American alligator moved its head and slowly closed its mouth, as if it could understand Liu Wei's words.

"Brothers, let's go comfort the big shark!" Liu Wei got up and waved his hand at the American alligator.

It retains its original static state and continues to enjoy the moisture of the sun.

Liu Wei walked in front of O'Neill, and O'Neill's right hand kept picking up stones on the ground and throwing them into the river.

Squinted at Liu Wei.

Liu Wei took off the diving suit he was wearing while paying attention to O'Neill's expression.

"Shark, are you still angry?"

"Liu, you lied to me, your deception left an eternal shadow in my heart!" O'Neill threw out the pebbles and looked back.

"Is it that serious?"

"Of course, tonight I'm going to have nightmares about damn crocodiles!"

"Hahaha, just get used to it, we will encounter more ferocious beasts on the next journey!"

Liu Wei originally wanted to comfort O'Neill, but when O'Neill heard this, he frowned again.

"Liu, participating in Bei Ye's show, I'm worried that I'll starve to death, and participating in your show, I'm worried that I'll die at any time!" O'Neill said very seriously.

A serious look.

Liu Wei looked at it and wanted to laugh, feeling like a cute Hanhan!

"Am I not still alive?" Liu Wei spread his hands and said, "shark, don't worry, there is nothing more meaningful than a full meal at this time!"

Liu Wei took out a few canned fresh steaks and a stone mill from the black technology backpack, put the stone mill on the fire and poured oil.

O'Neill's eyes stared straight at the stone mill and moistened his throat, and those emotions just now were lost at once.

After the oil is hot.

Liu Wei fried the steak on a stone mill.

"Liu, my steak cooking skills are very good, let me do it!" O'Neill took the initiative to ask, listening to the sound of frying on the stone mill, O'Neill was already salivating.

"OK, over to you, man!"

Liu Wei noticed the American alligator basking in the sun, and his eyes turned to it.

He walked up to the crocodile with a few pieces of fresh beef, "I'll apologize to you for a little favor!" and at the same time familiarize you with the taste of more meat and expand your food chain.

Your compatriots who grew up in the wild can find prey everywhere, not just fish and shrimp.

Grow your mouth and bite into the flesh of my hand, showing your craving for food!"

Liu Wei carried the piece of meat and shook it around the crocodile's mouth, the crocodile raised its head and bit Liu Wei, Liu Wei quickly let go, the beef fell into its mouth, and after a simple chew of two bites, it swallowed into its stomach.

"Pretty, I like your desires so much! The audience in the live broadcast room watched Liu Wei happily feeding the crocodiles there, envious, jealous and hateful.

"I want to feed the crocodiles too!"

"Come on! You can't feed the chickens!"

"It looks so cool!"

"It's really cool, take a bite of you, and it's even cooler to go to the hospital!"

The audience in the live broadcast room demolished each other.

Liu Wei returned to the campfire after feeding the crocodiles, and O'Neill looked proud, "Liu, try my craft!"

"You can't do it without alcohol at this time!"

"You still have wine?" O'Neill exclaimed.

"No red, beer OK?"

"Absolutely!" O'Neill took the beer from Liu Wei's hand, pulled the pull ring, took a sip, looked up to feel the warmth of the sun, turned his head to look at the flowing river, and sighed, "Liu, I feel like I'm dining in the best open-air hotel in the world!"

Liu Wei ate the steak and said with a smile, "I said I wouldn't starve you! Today your physical exertion is very large, let's find a suitable location on the shore to set up camp! Rest for the night, and continue to move forward tomorrow!"

"Liu, can you tell me in advance what we'll encounter next?"

Liu Wei smiled: "I'm not sure, there is a lot of variability outdoors, such as poisonous snakes, bison, mountain lions, ......?"

Liu Wei shook his head and took a sip of beer.

O'Neill's eyes stared at Liu Wei, swallowed his saliva, and showed a stiff smile, "Let's eat first!"
