Time flies, and more than a month has passed since the summer vacation.

Lin Zixuan has successfully obtained his driver's license, and after research, he has successfully made samples of the solid-state battery he chose to manufacture and installed them on the car.

According to the information he found, the world had the concept of solid-state batteries as early as forty years ago, and solid-state batteries were also made thirty years ago, but mass production has not yet been achieved.

Today's solid-state batteries can only be prepared in high-end laboratories and can only be used in cutting-edge fields.

The solid-state battery he made has far exceeded the storage efficiency of existing solid-state batteries, and has already had a mass production process.

This is because he has chosen a new type of solid-state battery that is not much beyond the current technological level of society, considering the degree of social acceptance. Otherwise, it would be too shocking if he immediately installed a controlled nuclear fusion power station.

This solid-state battery is already twice as efficient as the latest technological data, and at least four times more efficient than the lithium battery on the market, which means that the same weight of battery can store more than four times the original power.

According to the development of science and technology, his battery is at least ten years ahead of the world, which means that it will take ten years for scientists to develop this battery. As for mass production, it will take even longer.

For a prospective sophomore, this battery is enough to show his ability.

If it cannot meet expectations, then come up with a more advanced one to dazzle their eyes.

Lin Zixuan's family has a car, but that is what his father drives every day, and he can't use it for modification.

It happened that he had already got his driver's license, so he asked his parents for 20,000 yuan in funds and bought a second-hand new energy car.

Lin's father and mother agreed very happily. In their eyes, all the money they earned over the years was to be left to their son, and how he spent it was his business.

Before, they were worried that their son would be controlled by the bad woman Li Qingya, so they didn't dare to give him too much money. But now that the two have broken up, there is no such worry, so there is no need to limit it.

Not far from his home, he rented a secluded warehouse for a short period of time as his transformation base.

Lin Zixuan started a series of transformations in this way. This second-hand new energy vehicle has been completely renewed, and the ordinary battery has been replaced with a new solid-state battery.

After testing, this carefully transformed new energy vehicle also only takes one hour to fully charge, but the power is five times that of the previous one.

With the same battery mass and volume, his battery has five times the power of other batteries, which means that this car can now run about 2,500 kilometers as long as it is fully charged.

Since the solid-state battery he took out is a relatively basic version, it may only run about 2,000 kilometers in winter, but for the batteries in this world, the situation of reducing the battery life by half at any time is probably a dimensionality reduction attack.

This is simply a dream car for tourists.

He secretly modified his car without telling his family, and they probably still think it is an ordinary car.

During this period, he also received a call from Li Qingya, but he hung up after they said a few words.

This made Li Qingya very angry, and she said she would make him look bad.

There was still half a month before the start of school. Lin Zixuan said goodbye to his family and drove a second-hand car to school.

With a guaranteed range of 2,500 kilometers, he no longer had to worry about running out of power on the way. Even if he ran out of power, he only needed to use the charger he modified, and he would be full of energy again in an hour.

Lin Zixuan looked up at the sign of "Love Home Welfare Home" and knew that he had reached his destination.

This welfare home is a bit far from Linzhou University, but the original body would pass by here when he went to the park, so he was not unfamiliar with the area.

"Xiao Lin, are you sure you want to teach the children in our welfare home?" The gray-haired director asked in an expectant tone.

She was quite surprised when she heard Lin Zixuan's idea. Linzhou University is not close to here, and there are many welfare institutions that are much closer than their "Love Home".

I don't know why Xiao Lin chose to come here to volunteer, but she is definitely welcome.

"Yes, Dean Auntie, I just want to do something for the children." Lin Zixuan confirmed.

He looked at Dean Chen Mei in front of him. The years have eroded mercilessly, making the middle-aged aunt, who is only 53 years old, already

She has a head full of white hair and looks like an old woman in her sixties. All this shows that she has worked hard for the welfare home.

This "Home of Love" welfare home is where Yang Kexin often comes to volunteer.

After all, she is very popular among students in school. There will always be people asking for her contact information on the road, which makes her very annoyed, so she always refuses passers-by who approach her.

Yang Kexin was named the most beautiful girl in the law department at Linzhou University. This is the result of her usual dislike of dressing up. If she dresses up a little, it is not a problem to be named the school beauty.

Whether inside or outside the school, such a beautiful female college student has no shortage of suitors.

The only best opportunity to contact Yang Kexin is in the welfare home where she can relax.

The "Home of Love" welfare home accepts children who have been abandoned for various reasons, all of whom are poor people.

Their bodies will have some defects to a greater or lesser extent, and children who grow up in welfare homes lack a sense of security, and psychological problems are even more common.

When sleeping at night, I often hear children crying "Mom" while crying, so volunteering is also a job that requires a lot of patience.

They have lived in the special environment of the welfare home since they were young. Although they have the careful care of the director and other caregivers, there are too many children here, and they can't take care of everything. After all, they can't compare with the company of their biological parents.

In addition, the outside world has a deep prejudice against children in the welfare home, and children who are a little older will be more sensitive.

Although he has other purposes, seeing the thin bodies of the children in the welfare home and their desire for family affection, he decided to do something for them.

"Auntie Director, our school hasn't started yet, and I don't have a place to live now. Does our welfare home have extra beds?"

"Yes, of course, I'll ask the caregiver to clean it for you."

At night, Lin Zixuan was lying on the bed, and he vaguely heard a lot of crying in the children's dormitory. He pondered for a moment and picked a leaf and put it to his mouth.

Suddenly, a soft voice sounded, passing through the thick walls and into the ears of the children in the welfare home, soothing their wounded hearts.

The entire welfare home suddenly became quiet, and even the sound of insects disappeared.

After a while, the children slowly fell asleep.

Dean Chen Mei heard the voice, looked in the direction of Lin Zixuan with a meaningful look, and then fell asleep peacefully with a smile.
