Sure enough, as Lin guessed, just a Tao Te Ching is enough for the other party to pay a lot of things. In addition to the purification array, the alchemy master also subsidized the formation he owned, and even added alchemy techniques and alchemy recipes, as well as some spirit stones to satisfy equal exchange.

After exchanging enough things, Lin did not take action immediately. She was preparing to directly integrate the purification array into the formation she was preparing to arrange. However, her understanding of the formation was actually not as good as that of the magic array. After all, she could only have some simple Qimen Dunjia, and there were not many formations.

So, before that, she still needed to learn formations. As we all know, formations test people's computing ability. It is very difficult for people without mathematical talent to learn formations.

What a formation needs to calculate is the orientation. It is very important to arrange a formation. The corresponding positions of different formation nodes are very important.

The formation is actually a means of using magnetic fields. Different formations can produce magnetic fields with different effects. This magnetic field and electric magnetic field are different. It requires different objects to react with each other at different positions to be generated. Therefore, the formation requires a lot of calculations.

In addition to the already refined array disk and array flag, which are already equipped with magnetic fields and do not need to calculate the orientation, other array arrangements require consideration of the materials required to arrange the array and the size of the array to calculate the effects that the magnetic field can achieve.

The cultivation of formations in the cultivation world can allow the formation master to judge the size of the magnetic field and the magnetic field attributes of a formation material. Lin never knew that formation cultivation could have such abilities.

The formation master has a special practice method. The practice mainly involves the cultivation of eyes. After cultivation, it is a kind of magic eye. This is a very orthodox way for formation masters to practice.

The formation master's practice of the mind and other cultivation techniques will not conflict. After all, whether it is a formation master, an alchemist or a weapon refiner, they can only be regarded as the six arts of cultivation, not orthodox.

As for why there are still specialists, of course, monks are also humans. If you want to learn it thoroughly, it is naturally impossible to learn everything. You can only choose one of them. Moreover, if you learn it thoroughly, you will not be unable to become an immortal.

In short, Lin can only temporarily put down her plan to arrange the formation, but it doesn't matter. She will take advantage of the years to get out the machines that deal with pollution first.

The copyright of those songs was quickly obtained. Lin sent the songs to the point where the recording was solved by the interstellar people themselves. They have evolved this kind of ability, but the number is too small and the effect is too poor. With these songs, it will be different.

The information they exchanged was quickly submitted to the relevant research institutes. Although they already have complete information, it is not that easy to make finished products. Many technologies are something that their current methods cannot achieve.

Therefore, even if you get the information, you cannot produce the finished product immediately. Although Lin has tried her best to get the old product that has been eliminated by Interstellar.

Lin, in her cultivation and study, also ushered in the college entrance examination and graduation. After successfully entering the Qing Dynasty, Lin discovered that Song Yuner had never caused trouble for her. Could it be that she would not let her go? The plot would not let her go, so the only possibility is that she discovered it.

In fact, it was not because Song Yuner gave up, but because the system reminded Song Yuner that Lin no longer had the heroine's halo on her body. Song Yuner didn't know that she had removed the heroine's halo on her body before she could do it, and she didn't know where the halo was.

So during this period, Song Yuner was busy looking for the whereabouts of the heroine's halo and walked in other plots.

There are many plots of the fast-moving article, including counterattack, replacement, revenge, and strategy, and this fast-moving article routine is to deprive the heroine of the halo.

Depriving the halo Lin also did this, but her way was to directly plunder the heroine's halo, while Lin's way was to prevent the heroine from leaving the plot, which led to the halo falling off and being successfully collected by the world.

Of course, the method used on Song Yuner is not suitable now. After all, this is just a small world where the heroine walks in the plot, and there are other worlds that can let the heroine walk.

Even if the world she chose is the core world, it is the same as being able to connect with other worlds. The only way is to deprive Song Yuner of the system, which can be considered as stripping the heroine's halo.

Both of them are doing this, it depends on who has the better ability. Lin is currently the one who has the upper hand.

However, Song Yuner's system can detect the existence of a halo, and sooner or later she will find it. However, she cannot remove the national meridian, and the national meridian is invisible. Only the leader of Guo Jia is directly related to the national meridian.

So if she wants to deprive this halo, she can only contact the leaders, and this takes time, which is just enough for Lin to develop her abilities.

After thinking about this, Lin was even less anxious. During the summer vacation, she went to the Academy of Sciences to study. After all, as a person who came into contact with the red envelope group, she was able to answer all kinds of strange questions from those people. In the past, they were answered online and then reposted by others. Now she has graduated from high school and has been arrested as a strong man.

Lin had no objection to this. In fact, she chose a mechanical major in college, so she was happy to come and take action.

And she knows many questions herself, and she doesn't need to ask the Star Prince at all. After all, she is a person who has already upgraded the mechanical mastery skills to level 5.

Although the future technology she learned is based on cards, cards cannot represent everything after all, so there are still some technologies that should be available.

With her joining, the technology, which was originally almost half understood, instantly accelerated its progress. At this speed, the required products will definitely be manufactured in a year.

However, it is not that easy to promote. After all, the cost is definitely not suppressed just now. The production process is a problem. Lin can only exchange some production lines for the interstellar elimination.

Fortunately, these production machines are much simpler than the previous pollution-treated machinery. After all, in addition to mechanical manufacturing, there are also some other chemical products to deal with pollution.

For example, melting agents that can harmlessly dissolve plastic products, fusion agents that can directly cause heavy metal elements in the sewage to condense and produce chemical reactions, etc.

Because these are not earth's technological products, they use higher-end technologies and are more troublesome to produce. Fortunately, Liu Lin had traded over-decomposition and extraction machines before, so that some substances could be decomposed and extracted more refinedly and these agents could be prepared.

Although these agents require materials on Earth, they have never been used before. It took a lot of time to find the ingredients of the materials, and then extract the substances for research, and finally the configuration.
