Chapter 195
Tian Kun is right, sometimes more people are not necessarily better than fewer people.It may be an exaggeration to say that we have crossed thousands of mountains and rivers, but this journey is really full of hardships.Fortunately, everyone has overcome all these, and the end is within reach.The benefits brought by the team are fully displayed.

But everything has pros and cons, so what are the disadvantages brought by the team?
Shen Wei took Chen Xingyang's mobile power supply and plugged it in, but there was no response.

Shen Wei said to Xin Ling: "Little Mimei, borrow your data cable, mine seems to be broken."

Xin Ling: "Who is your little fan girl? Are you so bloated?" The cursing was cursing, and the data cable was still handed to Shen Wei.

Plugged it in, still nothing.

Chen Xingyang, Yu Fan, and Guo Na had already walked more than ten meters at this time, and they saw them playing with something behind.

Chen Frameyang shouted: "Hey, what are you two doing?"

Xin Ling ignored Chen Jianyang's call, but said to Shen Wei in a panic: "Oh my god, Brother Mao, you won't damage our power bank, will you? We only have such a big power bank !"

Shen Wei also looked a little embarrassed, and said, "Damn, I didn't, I just plugged in the cable. What's going on?"

Xin Ling felt something was wrong, and shouted to Chen Xingyang: "Hey, wait a minute, something is wrong! Come back."

The three of Yu Fan turned back again.

Yu Fan: "What's going on?"

Xin Ling pointed to Shen Wei and said, "Mao Wa broke our power bank."

I go!This is not a joke, everyone knows that once the power reserve in the team goes out of order, it will have a huge impact on the entire team.

Chen Xingyang was very angry and said: "Damn, you are my big brother, you are equivalent to throwing away half of our rations!"

Shen Wei couldn't argue with his words, and said, "I...I...I, no."

Guo Na comforted: "Don't worry, what if it's a problem with the mobile power supply?"

Chen Xingyang: "Impossible! My power bank is new! I have never used it before. It is a decent brand. How could it be a power problem?" Chen Xingyang's attitude was very firm.

Yu Fan was startled when he heard Chen Xingyang's words!Quickly asked: "Old Chen, you said your power bank is new? How long has it been since you haven't used it?"

Chen Xingyang said very positively: "I have never used it again. I bought this battery four years ago when we went out for training in the game. It turned out to be useless, so I kept it there with a full charge. It was brand new, and it was brand new before I left. It is fully charged, it is impossible to run out of power!"

Yu Fan sighed, and said, "It's over, Lao Chen, you may have to take the blame for this."

Chen Xingyang asked in surprise: "What does it matter to me? What do you mean?"

Yu Fan: "For lithium batteries, there is something called 'internal resistance'. Internal resistance is the resistance to current flowing through the interior of the lithium battery when it is working. Usually, the internal resistance of lithium batteries is divided into ohmic internal resistance and polarization. Internal resistance. Ohmic internal resistance is composed of electrode material, electrolyte, diaphragm resistance and contact resistance of various parts. Polarization internal resistance refers to the resistance caused by polarization during electrochemical reaction, including electrochemical polarization internal resistance and concentration Poor polarization internal resistance. The chemical reaction of the lithium battery begins at the moment when the electrolyte is injected. Not satisfied."

Guo Na: "That is to say, although this mobile power supply is new, in fact it has been being consumed at an accelerated rate and its internal resistance has increased."

Chen Xingyang was also a little panicked, and said, "Ah? But the battery shows 40%, what's going on?"

Yu Fan: "The voltage of this mobile power supply has been disordered, and the power display is naturally inaccurate. This is why many old mobile phones suddenly shut down and cannot be turned on again when they still have 20% power. Or the last power consumption of many batteries Very fast."

After hearing this, Shen Wei breathed a sigh of relief, and there was no need to take the blame for it.Although there is no need to take the blame, more troublesome problems have emerged. Everyone is now facing a situation of insufficient power, which makes everyone's travel plan have to face a major change.And this is what everyone knows.

Shen Wei: "Everyone report the battery level of your phone. I'm 15%."

Xin Ling: "48%."

Yu Fan: "38%."

Guo Na: "10%."

Chen Xingyang: "50%."

Everyone's battery is very low, which is very pessimistic.

Chen Xingyang: "Turn off your mobile phones first, and keep mine. Power saving is a top priority now."

Everyone turned off their mobile phones silently. Everyone had serious expressions and was unwilling to speak. Everyone knew what they were about to face.

Chen Xingyang spoke first: "Shen Wei, how long will it take from here to the red pine forest in the west?"

Shen Weiwei shook his head while waving his hands and said: "This time, you have to listen to me. Don't think about finding ghosts and gods to cover grass. Now that everyone's battery is stored, it's good to be able to return to the voyage smoothly. The red one you mentioned The pine forest is not necessarily the red pine forest you are looking for. Stop taking fearless adventures, the most important thing now is to go back smoothly."

Yu Fan was not reconciled: "But we are already here..."

Shen Wei was very tough, and said: "I don't care what you say. I didn't cause all this, all of this was caused by you, the path you chose, the risks you took, and the problem with your own power supply. It's your fault. We don't need to risk your mistakes."

Chen Jiayang and Guo Na looked at Xin Ling, Xin Ling has always loved adventure.

But this time, Xin Ling seemed to feel the fear ahead, she hesitated to speak, even such a nervous girl showed the fear that a human should have in this extreme situation.

Shen Wei spoke for Xin Ling: "Don't forget that you are the police. Your duty is to protect people's safety, not to bring everyone into danger. I don't object to you investigating the case, but this is not based on harming the public. superior."

Chen Xingyang was taken aback for a moment, he didn't expect Shen Wei to bring up this reason, and wanted to say something.Yu Fan patted Chen Xingyang on the shoulder, shook his head, and said, "Shen Wei is right, they have no obligation to accompany us to take this risk again. It is also our duty to protect the safety of the people."

Chen Frameyang didn't say anything more.

Guo Na: "Then what are you two going to do?"

Shen Wei: "Of course I'm going home. What else can I do?"

Guo Na: "But do you know the way? I think it's better for everyone to act together?"

Shen Wei: "Thank you, kind lady, according to the map, we can take the right way back. In fact, I have marked the way back this morning. Your police officer Chen also knows it. You will also take this way when you come back. On the way. If we arrive first, we will come back along the way to pick you up. Our battery is basically enough to save."

Guo Na: "If the battery is not enough, or if there is any accident, call for help immediately! Remember, don't be brave."

Shen Wei wiped his nose and said, "Don't worry, the basic operation."
