Chapter 452
Desperation itself cannot actually stimulate people's potential.What really stimulates people's potential is the unyielding spirit in desperate situations!

Only one bullet left!

All four of Yu Fan knew about this situation.To make matters worse, the wolves seem to have sniffed the message, too.

They began to surround them from all directions.

Yu Fan, Cao Ben, Yi Rui, and Guo Na are back to back, getting closer and closer.

Guo Na leaned close to Yu Fan. Although she couldn't see Yu Fan's face, she felt a kind of peace through Yu Fan's solid back.This kind of calm made Guo Na willing to face her impending death calmly.

Guo Na knew that this was the end of the matter, and if he didn't say some things, he might lose his chance. Guo Na said affectionately to Fan: "Brother Yu, although we have nowhere to go, until the end, I can be buried with you in the In this pile of fallen leaves, I have no regrets."

Yu Fan was very moved, but at this moment, he didn't know what to say.

Cao Ben cheered up and said, "Life is such a fucking thing, even though Laozi will die later, he must find a way to use this last bullet to blow the head of that wolf king!"

Leaf pile?bullet?

In his desperation, Yu Fan instantly entered the breath-holding flow mode. This is the world in Yu Fan's imagination, and he re-scanned everything around him.All substances are cataloged in a list, these lists are retrieved and screened automatically, and then the substances are thrown into an imaginary chemical reactor.

That weird black shadow appeared again, and it slowly floated towards Yu Fan.This time, Yu Fan did not back down, and stood firmly in front of the reactor.His mood at this time was unusually calm, and at the most dangerous moment, his mind was surprisingly calm.Coupled with Guo Na's warm confession, Yu Fan felt that his back was full of warmth.

The black shadow was about to approach Yu Fan, and it stretched out its claws, ready to catch Yu Fan.At this time, the chemical reactor imagined by Yu Fan produced the result of the reaction.Yu Fan opened the reactor calmly, and the reactor burst out with an incomparably brilliant light.The light dispelled the mysterious shadow in the flow mode, and illuminated the whole picture brightly!
Yu Fan returned to reality, only two seconds passed.

Yu Fan said to everyone: "Don't give up, besides bullets, we still have one hole card!"

Cao Ben: "What?"

Yu Fan: "Chemistry!"

It was too late, but soon, Yu Fan shouted: "Everyone, gather the fallen leaves under your feet! Cao Ben, take out the bullets and open the bullets."

Guo Na and Yi Rui listened to Yu Fan's command and gathered the fallen leaves on the ground.

While picking out the bullet, Cao Ben asked in a panic, "Old Yu, what are you doing? How do you do it? How do I get the bullet?"

Yu Fan: "Use your teeth to bite. Didn't you use your teeth to open the wine bottle last night? (Chapter 434 details foreshadowing) This is no more difficult than the wine bottle cap."

Cao Ben nodded, bit hard with his teeth, and really bit off the bullet.

The operation of the four people stopped the wolves, and they started to retreat involuntarily.They seemed to read it, and the fear in the hearts of the four people began to dissipate!They may ask in their hearts: "What do these four humans want to do?"

Yu Fan: "Yi Rui, tear off a small piece of cloth from your clothes."

Yirui cut a piece of cloth from his clothes with a knife and handed it to Yu Fan.Yu Fan took the cloth strip and blocked the mouth of the bullet case with the cloth strip.

Yu Fan handed the "modified" bullet to Cao Ben, and said, "Old Cao, load it, and then shoot this pile of fallen leaves!"

Cao Ben got the order, took the bullet, loaded it, and the action was done in one go.

Yu Fan looked around the wolves with a smile, and said calmly, "Don't you guys like to taste fear? Now, come and taste what we specially prepared for you——hope!"

boom!With a gunshot, Cao Ben fired the last bullet into the haystack!
In an instant, the haystack was on fire!

The wolves panicked now, they were afraid of the flames, and when they saw the flames, they retreated further.

Yu Fan, Guo Na, Cao Ben, and Yi Rui used the dead branches and fallen leaves around them to make the fire bigger and bigger.

Cao Ben even picked up dried fruit on the ground and ignited it, threw it at the wolves, and muttered something like "go ahead with the wind, and pay attention behind you" to vent his emotions.

The wolves were stunned by the flying flames, and some wolves were even ignited in the panic, running wildly among the wolves.

The wolf king was also in a panic, the "little brothers" under his hands had become a mess and did not listen to his command.The wolf king wanted to take a step forward, but the raging fire finally made it fearful. After several times of probing, it had no choice but to grit its teeth and retreat.

The wolves fled in embarrassment and scattered.

It was safe, and the four of them finally breathed a sigh of relief.call~~~
"Old Yu, how did you do it?" Cao Ben finally remembered to ask Yu Fan how he started the fire.

Yu Fan smiled: "Thanks for your reminder! You are a clever little panda!"

Cao Ben: "Huh? Hahaha? What did I do?"

Yu Fan patiently explained: "A bullet is basically composed of four parts: warhead, shell case, charge (propellant), primer (or detonator). This basic structure has hardly changed since the second half of the nineteenth century. Whether it is a single-base, double-base or triple-base propellant, the basic component is nitrocellulose. Nitrocellulose, also known as nitrocellulose, cotton collodion, etc., is a nitrate ester. It is the product of cellulose and nitrate esterification. Product.Cellulose nitrate is obtained by the esterification reaction of refined cotton with concentrated nitric acid and concentrated sulfuric acid.Cellulose nitrate is a white fibrous polymer resistant to water, dilute acid, weak alkali and various oils. Insoluble Soluble in water, soluble in acetone, ethyl ether and ethanol mixture. It is easy to change color in the sun, extremely flammable, smokeless, and releases a large amount of gas instantly. Different degrees of polymerization have different strengths, but they are all thermoplastic substances. It is easy to change color in the sun. And extremely flammable."

Guo Na helped Yu Fan conclude: "Brother Yu removed the warhead and plugged the bullet hole with a cloth strip, so that the flame generated by the nitrocellulose would be 'spit' directly into the haystack after pulling the trigger, igniting the haystack. .”

Yirui and Cao Ben suddenly realized.

Yirui: "In the future, I must study chemistry well. It can save lives at critical moments!"

Yu Fan encouraged Yirui: "I believe that you will be able to do it in the future."

Cao Ben found some tree trunks and dead branches nearby, made a few simple torches, lit them, and distributed them to everyone, saying: "Let's go, let's go back quickly, those wolf cubs will come again in a while, we will be in trouble .” Everyone took the torches and started to start again.

Yu Fan whispered to Guo Na: "Na Na, thank you, thank you for bringing me courage at the critical moment, let's not separate in the future, okay?"

Guo Na nodded shyly.

"Hurry up, keep up." Cao Ben shouted in front.

Yu Fan took Guo Na's hand and ran forward...

Not far away, a bow and arrow pointed at the four people, shook their heads, and disappeared...

　Fire can make people realize their ideals, which is the fire of ideals; fire can make people out of difficulties, which is the fire of belief; fire can make all things feel warm, which is the fire of warmth; fire can make everything come to naught, which is the fire of Furious Fire - Nitrocellulose
