Chapter 202
It is not light that illuminates people, but people's hope for life.

Yu Fan put one piece of tinfoil on the positive pole of the battery and the other on the negative pole of the battery, and then carefully touched the brush-like tentacles of the two pieces of tinfoil little by little. After several touches, The tinfoil started to smoke!

After more than ten seconds, my God, the tinfoil started to burn. Guo Na hurriedly pulled a dead leaf over to ignite it. The dead leaf was ignited. The fire is finally up!
"Fuck, awesome!" Chen Jianyang screamed, even breaking his voice.

Yu Fan carefully protected the flames, and said, "Bie Lang, old Chen, be careful to blow out the flames."

Chen Xingyang came to help with a flattering smile, the fire finally got big, and the fire piled up.

Guo Na was also very happy, and let out a long sigh of relief: "That's great, cough cough, now I don't have to freeze tonight, cough." Guo Na coughed a few more times, probably because he was choked by the smoke.

Chen Xingyang's heart sank, and then he remembered to ask Yu Fan: "Old Yu, how did you borrow this lighter? What is the reason for this?"

Yu Fan explained: "This is actually a short circuit phenomenon. In a circuit, using a conductor to directly connect the two poles of the power supply will form a short circuit of the power supply, and the tinfoil itself contains metal aluminum, and the resistance of the tinfoil is small. When the power supply is short-circuited during contact, a very large current is formed, and the strong current causes the temperature of the tinfoil to rise, and when it reaches the ignition point, it will smoke and burn."

Chen Xingyang wondered: "Why do I remember that short circuit is not a logistics phenomenon? How come you have become a god of chemistry?"

Yu Fan smiled and said: "Physics and chemistry are not separated. The ability of a battery to generate electrical energy is due to chemical energy. A battery is a chemical power source. It consists of two electrochemically active electrodes with different components to form positive and negative electrodes."

Chen Xiangyang laughed happily: "Hey, it doesn't matter whether he is the god of chemistry or the king of physics, the one who can light us up is my elder brother."

As the sky gradually darkened, the three of them sat around the fire to keep warm, but no one said a word, because the two days of running around had already made people sleepy.The night wind in the mountains outside the pit was blowing, but the three people in the pit were not bad. They were not affected by the mountain wind. This small slope was both windproof and warm, very warm.

The three of them sat there quietly for nearly two hours. In a daze, Yu Fan heard a few coughs.

"Cough cough." It was Guo Na. Yu Fan concentrated his mind slightly, and saw Guo Na throwing firewood into the fire with one hand, and coughing while covering his mouth with the other hand.

Chen Xingyang next to him was already snoring. This guy's sleep quality is really good, no matter what happens, he can't stop his sleep.Presumably, Yu Fan often sleeps very lightly. Because of his high sensitivity, his sleep is easily disturbed. In fact, Yu Fan's nerves are always in high tension. fault.

"Guo Na, are you awake?" Yu Fan cared softly.

"Well, I was lost for a while. I was afraid that the fire would go out, so I got up to add more firewood. Cough cough." Guo Na whispered, and coughed again.

Yu Fan: "Why are you coughing? Are you feeling unwell?"

Guo Na: "No, it's just that my throat is a little itchy. I cough when I speak." Guo Na squeezed his throat with his hands.

Yu Fan stared blankly at Guo Na, Guo Na's cheeks looked rosy and lovely under the reflection of the campfire.

Cough cough cough, cough cough cough cough.Guo Na coughed twice more violently.Sensing Guo Na's strangeness, Yu Fan walked up to Guo Na's side and touched Guo Na's forehead with concern.

Ah!So hot!

Yu Fan was surprised: "You have a fever? When did it happen? Why didn't you tell me?"

Guo Na cleared his throat, and said in a low voice, "It's okay, there's nothing serious about it. Maybe it's just a bit of a cold, it's okay."

Yu Fan: "Did it start this afternoon?"

Guo Na nodded.

Sure enough, when the three of them ran for their lives in the afternoon, they were sweating profusely. When the cold wind blew, the pores shrank violently. They were most likely to catch a cold and have a fever. Coupled with the long-distance travel and irregular diet, the body's immunity had already declined, and it was easier to get sick Yes, it's really embarrassing for Guo Na.

Guo Na rubbed her slender hands, then warmed herself by the fire.Yu Fan couldn't help but went up and touched Guo Na's hand, oh my god, it's so cold.

Yu Fan didn't even think about whether his behavior was a bit disrespectful, his first reaction was just to care about the severity of Guo Na's fever.Guo Na's hand was suddenly "attacked" by Yu Fan, and subconsciously flinched shyly.Guo Na blushed and said nothing.

Only then did Yu Fan realize that his actions were a little rude.Embarrassed, Yu Fan took a piece of firewood from the ground, threw it into the fire, and said, "Your hands are so cold, let's light up the fire a bit so that it will be warmer."

Guo Na pursed his lips and nodded, and threw a piece of firewood into the fire, then reached into his clothes pocket, took out a piece of thicker paper, and was about to throw it into the fire as well.

Yu Fan asked curiously: "Na Na, why are you doing what you do with such a thick stack of paper?"

Guo Na looked at the fire in a daze, and said, "Oh, this is the piece of paper we used to play with Bixian a few days ago." (Chapter 166 Foreshadowing)
Yu Fan recalled the time when everyone played pen fairy together a few days ago, but what did Guo Na still do with this piece of paper?Could it be...

"By the way, Brother Yu, what did you call me just now?" Guo Na's words interrupted Yu Fan's illusion.

Yu Fan came to his senses: "Ah? Did I call you Na Na just now? Uh, I'm sorry, I just blurted it out. If you don't like it, I won't call you that next time."

Guo Na narrowed his eyes, smiled and said to Fan: "No, I really like you calling me that, hee hee. Cough cough cough." Guo Na coughed and coughed several times.

In Yu Fan's heart, there seemed to be a deer bumping back and forth, and his heart was warm. Yu Fan didn't care about what happened tomorrow, and this moment was the most warm time.Originally, he hoped that this dark night would pass quickly, but now, he hoped to stay together with Guo Na by the fire.

Guo Na said softly to Fan: "Brother Yu, in fact, there are no fruit trees after turning over the hillside, right?"

Yu Fan argued: "Yes, how could it be..."

"Brother Yu, you can't lie to me. You said that to encourage us. You always think about others and bring hope to others, but you choose to endure loneliness and fear alone. After spending so long with you, I feel like I understand you more and more. Cough cough, cough." Guo Na interrupted Yu Fan's defense.

Yu Fan's eye sockets suddenly felt a little wet, and a big lock that had been dusty for a long time seemed to start to shake deep in his heart.Yu Fan pretended to take off his glasses and wiped the lenses with his clothes to divert attention.

Yu Fan pretended to be joking: "Na Na, have you learned to read other people's hearts now?"

Guo Na said seriously: "I don't want to read other people's hearts, I just want to understand you."
