First of all, the battery life of new energy vehicles is generally two to three years, and the battery stack must be replaced when it expires, otherwise there are potential safety hazards. But you don't have to worry about this for a gas-powered car, if you maintain it well, a car can run for ten years without a problem.

Secondly, if you think about the electric car at home, you can understand that the power and range of the battery stack are seriously insufficient.

Especially in winter or summer, when it is hot, such as a rated range of 500 kilometers, but if you turn on the air conditioning, you may only be able to run 200 kilometers, and then encounter a rugged road of climbing type, it is likely that you will run out of power after only running more than 100 kilometers.

In the wilderness, where do you go to recharge? Even if someone is nearby, the power of your charging is unbearable for ordinary wires!

A car that burns gas, goes to the gas station, and fills up with gasoline in a maximum of ten minutes, but what about a charging car? It takes several hours to charge a single charge, and if there is an emergency, the battery is low and the vehicle cannot be started, then it can only be resigned to fate! ”

Li Yi asked puzzledly: "Doesn't that mean that there is no place for cars that use electricity?" ”

Lao Xing shook his head: "You can't say that, the times are developing." The biggest obstacle to charging a car at the moment is battery life and range.

For example, there are generally two kinds of battery stacks on the market now, one is lead-acid batteries, which have long life and high safety, but occupy large space and high weight.

The second is lithium battery, a new type of battery, which is simple and convenient and fast to charge, but also has the shortcomings of low safety, easy to cause accidents, and low charging and discharging power.

As long as there is a light weight, small area, high endurance battery appeared, it will be lightning fast to eliminate the gas-burning car, after all, who doesn't want to save trouble? Who wouldn't want to be eco-friendly? ”

Li Yi thinks about it, for example, the electric car at home, the battery can be used for two years at most, otherwise, the endurance will plummet, and there will be potential safety hazards.

Although trams say that they are environmentally friendly and efficient new energy vehicles, what about batteries? All batteries are a combination of heavy metals and strong acids, and the production process is probably more resource-intensive and polluting than refining oil, right?

Lao Xing began to chatter again: "In fact, many people also understand the benefits of electric cars, low prices, and subsidies. But you have to think long-term.

For example, an electric car requires four batteries, which are a mixture of heavy metals and acidic solutions.

Once discarded, almost a radius of tens of meters of soil will be contaminated with heavy metals, and the leaking acidic solution will also contaminate the nearby groundwater, resulting in deep water that is toxic and undrinkable for decades. ”

The boat of time slowly passed by in the exchange between the two, and the high-speed exit of Zhushan County in front of him was already appearing, and the corners of Li Yi's mouth curved: "Lao Xing, thank you." ”

Li Yi could see that Lao Xing was not chatting on purpose, but was distracting his nervous mental pressure, and Lao Xing smiled and said nothing......

"Li Yi! This way! After getting off the highway, as soon as Li Yi opened the car window, he saw Dong Xiaonan waving and calling him on the side of the road.

"Huh? Sister Nan? Li Yi was shocked, how could Dong Xiaonan come all the way here to pick him up?

"Lao Xing, park on the side of the road." Li Yi shouted a little excitedly, and took out his mobile phone to turn it on.

"I heard someone's voice coming in

Like the river whimpering in a dream

I see the pace of the far away whom

Cover the sad eyes when you say goodbye

What I don't understand is why you are willing to ......"

At this moment, Li Yi's mobile phone suddenly rang, and when he picked it up, he saw that it was Tang Fengjie?

"Li Yi, where have you been? I heard Shuyi say that you are in distress on the highway? Is it serious? How is Lao Xing? The strong voice of concern on the Tang Festival made Li Yi's heart warm.

gave Tang Fengjie a brief report, asked Lao Xing to go to Tang Fengjie to explain the actual situation, and he got into Dong Xiaonan's car by himself.

"Where are the claws?" It is said that this little Bie is newlywed, Li Yi gave Dong Xiao a French wet kiss when she got in the car, and when she was confused, a pair of big hands slid deeper, and was suddenly twisted by Dong Xiaonan, shouting.

"Huh? Forehead? Mistakes, mistakes!? Li Yi embarrassedly withdrew his big hand and scratched his head.

"Humph! Blunder? I think you did it on purpose, pretty much it! That's all that you men have on your mind all day! Sit down, Mom is still waiting at home! Dong Xiaonan pushed Li Yi away, fastened his seat belt, and turned his head to say.

Li Yi was even more embarrassed, didn't he come back this time just to visit his mother? How can you ...... here? No wonder the old man said that his sons had married daughters-in-law and forgot their mothers, so he almost died.

Dong Xiaonan looked at Li Yi's embarrassed expression while driving, and felt a little proud in his heart. But the inner line of defense must not be lost, at least before marriage, and that kind of distraction must not happen again.

Dong Xiaonan pointed to the tablet on the console, asked Li Yi to open it, pointed to one of the videos, and said, "This is the video I copied, you can take a look." I looked like a bear, black and black, with a lot of strength, able to tear down a fence, and obviously not a small beast.

The secret service also sent someone to check, and the scene was a series of footprints, without any fur or teeth falling off, and it was also strange that this beast only ate big geese, and did not even touch a few pigs raised on the side. ”

Li Yi was startled, as if he had thought of something in his heart, but he couldn't remember it, so he could only respond and say: "Also, if it is a large beast, it must be more interested in fat and strong domestic pigs, how can it be interested in a big goose with feathers all over its body?" Incomprehensible? ”

Li Yi said as he turned on the video and watched it carefully.

After about three minutes, Li Yi frowned violently, as if he had found something terrible, and his face turned iron blue.

"It's back!" Li Yi muttered to himself.

"What? Who's back? Dong Xiaonan heard very vaguely, turned his head and asked.

"Oh, it's okay, let's not go home first, let's go to the goose factory to have a look!" Li Yi watched this video and became more determined in his heart to fly by. No wonder the beast only ate the medicine-fragrant goose, it turned out that he was going to the medicinal liquid.

Dong Xiaonan didn't refute, thinking that Li Yi had discovered something important, so he changed his route and went straight to the goose breeding factory.

In less than five minutes, Li Yi saw that although the goose factory had been cleaned up, there was still a faint smell of blood.

Looking back at the place where he mixed the liquid, sure enough, there was nothing left that was licked!

Li Yi looked at the tablet in his hand again, it was the camera that filmed the scene of this 'beast' excitedly licking the medicinal liquid, and let out a low roar while licking, as if it was protecting food.

In rural areas, geese are used to watch the home, and where there are geese, there are no weasels, which also brings a sense of security to chickens and ducks.

In the video, when this beast was licking the medicinal liquid, several big geese rushed up to twist it, but the disparity in strength was too great, and it was directly bitten to death by the 'beast' on the spot, however, the beast seemed to have discovered that the body of these medicinal geese also had the smell of medicinal liquid, so they began to kill wildly, and eventually led to dozens of geese being slaughtered......

Li Yi figured out the overall situation, slapped his thigh, and regretted a little that he forgot about the fact that the medicine was stolen in the past? This is obviously the same creature, because it attacked the goose factory because it stole the medicinal liquid.

"This brute! Don't let me catch you, or I'll have to stew you!" Li Yi looked at the frightened appearance of the geese all over the garden huddled in a corner, and he didn't even dare to make a sound, so angry that he really wanted to peel the skin and cramp the 'beast' that plagued the geese.

"Don't blame yourself, even the secret service said that this beast doesn't seem to be an ordinary beast." Dong Xiaonan comforted.

"Huh? Are you two really here? Just when Li Yi wanted to take a good look at the beast's footprints on the ground, Li Yang appeared.

It turned out that the family was counting the time, and Dong Xiaonan should go home to pick up Li Yi, but he didn't see anyone for a long time, and he didn't call.

Su Haitang guessed that Li Yi must have gone to the goose factory, so he asked Li Yang to come to the goose factory to find them.

"Brother, how is our mother?" Li Yi looked up and asked.

Li Yang: "Well, it's not a big deal, it's just the sequelae of blood sickness." Our mother didn't dare to look at the chickens killed during the New Year, not to mention the bloody place where the geese were bitten by wild beasts, even I was scared when I looked at it, not to mention that our mother was still a little faint. ”

"Brother, what do you think?" Li Yi pointed to the footprints on the ground, Li Yang has liked all kinds of animals since he was a child, especially the animal footprints are very studied.

"Huh? This ......" Li Yang was also a little troubled, and he didn't know how to say it. After a moment's hesitation, he said, "I think this should be a dog, but it's going to be a very big one!" ”
