After the production line came out, it started to promote it. This actually has some troubles. In fact, modern times also have some measures to prevent pollution, but it costs money. Those unscrupulous capitalists are not willing to spend money to do this.

That's why there are all kinds of pollution nowadays. However, this time Guo Jia has stepped up his efforts. Lin can see a lot of news on the Internet and various complaints from netizens.

For example, under a certain headline, there are a bunch of netizens:

"Wow, Guo Jia doesn't know what to do recently, and it's very effective to control pollution."

"Yes, there is a garbage dump near my house. It smells so smelly. I don't know what those people have done recently. All the garbage has been disposed of, and even the white pollution is gone."

"What's the matter? We have a river here because of the factory's sewage discharge, which has become dark and stinky. It's much better now."

Lin knew that it was just a treatment of symptoms but not the root cause. It was not that difficult to deal with those polluted, so she worked hard to learn the formation. Of course, in addition to her, there were other people who were also learning.

However, after studying the purification array, Lin felt that this might not be suitable for use. She told Zhu Xi and Zhou Muyan: "I have studied this and found that this filth refers to many things, such as excrement, some harmful chemical products, and even nuclear energy can be considered."

In other words, if she directly uses the purification array to purify the whole country and even the world, the earth will eventually be clean, but it will be completely clean.

Therefore, it is not feasible to use anything across the country in one go. The best thing is to create a smaller formation to evolve one by one.

Lin found some materials to refine the array plate, and then the supporting array flag, and then refined a lot more to let someone deal with it. When she felt that it was almost done, Lin also changed the spirit gathering array again and then prepared to arrange it.

During this period, she also found a lot of materials that can be used to arrange the array, and the formation and location were calculated, so the arrangement was simple.

After the arrangement was made, Lin began to study how to deprive the system. She had secretly observed Song Yuner from a distance, but was almost noticed by the system.

After that, she didn't dare to do anything randomly. After all, she was still too weak now and could only try her best to improve her cultivation.

"School sister, I like you, can I date me?" Lin was stopped by someone on that day, and a bouquet of fiery red roses were handed to her.

"I'm sorry, I don't know you." Lin answered directly.

"It doesn't matter, we can get to know each other first. I am from the junior high school management department, my name is Liu Xiao." The man immediately introduced himself. This is a man with a very handsome appearance, and he also has a noble temperament. It seems that his background should not be simple.

"Hello." Lin nodded.

"Can the junior sister enjoy her face and have a meal with me?" Liu Xiao sent an invitation.

"Sorry, I still have something to do, I'm afraid I don't have time." Lin shook her head and refused.

"That's how about tomorrow?" Liu Xiao was not discouraged and made an appointment for other times.

"No, I have to go to work after class, and I don't have time at will." Lin was a little sorry.

"That's it, then it's OK at noon tomorrow." Liu Xiao changed the time.

"Yes, then I'll leave first." Lin did not refuse.

"I'll give it to you." Liu Xiao said immediately.

"Thank you, no need." Lin refused, then walked past him and left.

Liu Xiao didn't stick to her. When she watched Lin leave, she found that she got into a car after leaving the school gate. There were other people in the car, and her eyes narrowed slightly.

After getting on the car, Zhu Xi asked: "Who is that person?"

"The senior in the third year is Liu Xiao." Lin replied, "You can investigate his background."

"You mean he has a problem?" Zhou Muyan's voice immediately became alert.

"He said he liked me, but I could feel that he had other purposes to approach me. In recent years, espionage activities in various countries have been frequent in recent years, so it is not surprising to notice me." Lin said.

"I understand." Zhu Xi immediately asked someone to investigate.

In recent years, the technology development of China z has been rapid. Although Lin said at first that she only exchanged environmentally friendly materials first, she later exchanged interstellar energy conversion technology to improve the utilization of solar energy.

In addition to solar energy, there is also hydrogen energy. All countries on earth have researched. After all, as oil and coal consume more and more non-renewable energy, it is necessary to develop new energy.

Although countries have achieved some results in the development of hydrogen energy, just like solar energy research, the conversion rate is too low to completely become the main energy source.

With the technical support of Star, they can completely use solar energy or hydrogen energy to replace gasoline and coal, and they are environmentally friendly and harmless, and there is no need to worry about losing it after consumption.

Another point is that these technologies have been studied, and now they have obtained higher-end knowledge to eliminate the original detours, which has accelerated their research a lot, and it has already achieved results at the beginning of this year.

Because most of the cars on the market are still gasoline cars, Lin also got some information that can be modified based on gasoline cars, so that there is no need to worry that most people will continue to use gasoline cars with high pollution because they can't afford to change their cars.

Of course, new cars are naturally to be promoted. Moreover, new cars are not ordinary cars, but speed cars. Speed ​​Lin has done them before. She can get them even without interstellar information, but that is difficult to explain.

So, she still exchanged information directly with this interstellar. Fortunately, the interstellar people seem to have some resistance to songs. After a long time, the effect of the song will be gone, so there is a lot of demand.

Lin actually asked why the Star Prince did not exchange the meditation mantra for the cultivation world, and then he knew that the Star Prince had exchanged it, but he didn't know if the system was not matched, which was useless to him at all.

Only then did she realize that it was not that it had not been used, but that it was invalid. Then Lin also learned about the evolutionary history of the interstellar side.

The origin of the interstellar plane is also the earth, but they entered the interstellar plane after experiencing the end of the world. However, they are different from the end of the world plane. What they experienced was not the end of the world caused by resource exhaustion, so some people escaped from the planet and entered the interstellar search for a planet suitable for survival.

After entering the interstellar world, the ancestors wandered in space for a long time, and the new generation were all born in spacecraft. Different places appeared at birth, and some people developed mental power.

Later they finally found a suitable planet, but although there is life on the planet, it is not completely suitable for people on earth to live in. So new mutations have emerged to make them adapt to the environment there.
