Because the three of them are themselves, what they want to do, Lin doesn't need to convey it in words at all, and others can understand it. The three of them stood in a corner of the magic tower and began to carry out the renovation project.

The main body of the second layer of the magic tower in the dream realm is almost perfect, but there are very few magic arrays engraved on it, that is, the magic program code that belongs to Lin's uniqueness. In fact, what kind of function to give to the second layer, Lin was still a little at a loss, and it was difficult to make up his mind.

Although there was work on the ranging program before. However, after a series of optimizations, the program code has become more concise and the computing efficiency has also improved, but the occupied capacity is ...... It also takes up less wall space. There is still a large blank space on the second floor.

The main body of the first layer is about the appearance of the star map, and when changing the reference point and displacement, the relative position of all the reference points must be maintained as much as possible. Maybe it's because the first layer is quite complete, so in terms of the explosion map, Lin has a better grasp than the lich.

And now it has been decided to be arranged on the second layer, strictly speaking, it has nothing to do with magic, what Lin intends to do is - the dimensional change of data.

Compared to the first layer, the foundation is magic light, and then the position of all light points is controlled by the program; The second layer is to use the calculation of the program to achieve the purpose of data dimensionality reduction. Moreover, the process is completely free of human subjectivity, and is determined by the procedure. This includes what data is eliminated and what is merged, and the criterion for the final presentation is how much information can be retained after projection to 3D.

This level of machine learning and algorithmic programming has been involved in many fields at the practical application level on the earth, and of course, there are quite a lot of results. Such as artificial intelligence, or face and voice recognition systems, etc.

In astronomy, this technique is widely used, such as judging star magnitude; Complex things like observing deep space and studying the meaning it represents and what kind of physical phenomena it represents from subtle changes in data. Therefore, Lin also has a certain understanding of various data analysis techniques.

Although at that time, I only used the kits written by others to perform calculations, but I also learned the relevant mathematical theories, so I am naturally no stranger. Now that I'm in a daze, I don't have a kit written by others, so I can only knock it out by myself.

Fortunately, everyone has the relevant knowledge, and they know what kind of results they want to get, especially with a tentacle monster to do experiments, and the progress is quite fast.

In the end, Lin carved the first version of the dimensionality reduction method, and he couldn't wait to leave the dream and return to reality.

I still sit cross-legged in the same place, in the position before falling asleep. Fen was standing not far away with his hands folded over his chest in boredom. The heel tip of the right foot touches impatiently. Surrounded by a mess of grotesque corpses headless or beheaded, it was impossible to see what they looked like before they were eroded.

"How long did I sleep?" Lin asked.

Sensing that someone had woken up, Fen stepped forward and reached for the golden pocket watch with one free hand. With one hand, he operated the pop-up cover, looked at it, and said, "You slept for about six or seven minutes." I was surprised to wake up so quickly. ”

Putting away her pocket watch, Fen walked over to a certain man. Bent down and look straight behind those glasses. After looking at it for a while, she said, "Leave me here alone, what do you gain, let's hear it." If I'm not satisfied, I'll have you look good when I go back. ”

What's the catch? Lin didn't know how to answer for a moment. And although he completed the first stage in the dream world, applied to the tentacle monster, there was no obvious change. Maybe it's because they can enter their dreams, and they have already gone through a certain degree reduction, that is, the screening of their own subjective consciousness, and they appear like that.

So after the first version of the method was completed, Lin decided to go back to the reality side and see for himself how it turned out.

But when you come back to reality, you look up...... Nothing has changed.

"Oh, glasses." Taking off the glasses that have their own magic isolation function, Lin rubbed his eyes and opened them again! The world seen has changed dramatically.

It's as fragmented as Picasso's paintings. However, relatively speaking, the layout of the original Yamauchi fortress has not changed, except that there are some parts of unknown meaning and some parts that are missing.

Tracks of strange colors appeared on the ground, and the colors kept changing. Tracing its origins came from the feet of those monsters, and it looked like the trajectory of their journey, and the direction in which they were going.

Because Lin saw a person moving his steps with difficulty, not only bringing the trajectory behind him, but also extending to his own position. And the monster that has been pierced by strange and slimy tentacles piercing its body, and its whole face is no longer human, but its body is colorful.

Observed, the part that radiates the aura is already the non-human part, and the part that is still human is bleak. From this perspective, it can also be seen that he is gradually assimilated by the tentacles on his body, and the part that belongs to the human body is becoming less and less.

Such a monster, as soon as it shows up, Fen shoots it with one shot. Because the magic bullet itself belongs to the energy condensation, just like the earth's tracer bullet, its shooting trajectory can be seen.

In Lin's special perspective, the magic bullet is like a snake, following a different and irregularity trajectory, hitting the monster's body. The impact points are scattered, not at all like the actions of this lich whose spiritual power is so powerful that it is enough to control the magic bullets.

As soon as the monster falls, as its life dissipates, the trail they leave on the ground fades. Even so, there are still countless ground tracks towards him, almost turning his surroundings into a colorful and bright place.

The reason for this, Lin thought that it should be those who appeared in the sky...... Well, eyeball-like stuff. In the part that is not part of the original mountain fortress, the rock walls of the ceiling are interspersed with some dark and deep ...... Deep space rifts?

There are many strange and indescribable things, which fill this strange vision, and it is difficult for Lin to fully describe what he has seen. It's all familiar, yet plausible. In fact, this is the result of the method of carving on the second floor of the Dream Magic Tower.

To do machine learning algorithms, it is necessary to have known answers or experience as reference data for training, and finally use the program to deduce the most reasonable results. In other words, everything Lin sees now is based on his original cognition, the result of sorting out those messy and redundant data. It's not that what he sees is really that.

But that thing in the sky is really like an eyeball, peeking into the world on this side. Or rather peeping at yourself.

…… Is this what it feels like to look at Sauron after wearing the Ring? But he's not a hobbit, and the oppression from that eyeball isn't as good as the feeling of staring at him when the lich next to him gets angry. It's just that there are not just one or two eyeballs, but one or two in every crack, and being stared at by so many eyeballs inevitably makes it feel a little hairy.

For someone who took off his glasses, he looked left and right for a while, and occasionally he had to kill two monsters that were close to him. Fen asked curiously, "Did you see anything?" ”

After thinking for a while, Lin said, "If they start peeking into the world, will they invade like this?" ”

"You can notice those!" After being surprised, Fen still answered Lin's question seriously, and said, "That crippled original body wouldn't do such a thing, unless someone in this world took the initiative to contact them. What you see should only be part of their instinctive reaction. It's like you once said, that reflex to knock on the knee. ”

"Even if you have a bunch of eyeballs?"

"Look, it's just your perception. The eyeballs are the organs used to see, and they are also your cognition. When they really react, when they want to invade a place, it is not a peaceful scene like the one in front of them. I should really show you the feat they did when they invaded the kingdom of God. Everywhere he went, there was destruction, and even the kingdom of the gods was fragile. ”

"In other words, even if those things look at us and come towards us, they can only be regarded as instincts."

"Oh, they're coming towards us, that's not good. Let's get this side of the matter out of the way. Talk about what happened to you later. ”

Fen made up his mind to take the mutilated body first, and then he had a lot of time to torture and extract a confession, and he was not in a hurry at this time. But the man got up, hugged the container, and said, "Go this way, follow me." Then, in a way she couldn't understand, she took a few steps and walked a considerable distance. Now she was dumbfounded.

Someone finally remembered to look back at the person next to them, instead of walking with their head down. This time, Lin felt strange, looked at the lich standing in the distance, and asked, "Why don't you leave, and stay so far away?" ”

Fen smiled sweetly, beckoned and said, "You come back, take my hand and go." I have something to confirm. ”

It should be a beautiful smile, but it makes someone shiver. Lin obediently returned to the former demon king's side and said, "This is not some kind of dating and shopping, there is no need to hold hands." ”

"Less nonsense!" Fen withdrew the magic gun in her right hand, stuck it back into her waist, and grabbed someone's hand with a ferocious slash. The contact between men and women should be a wonderful thing, but Lin just wanted to leave with his hands.

It's just that if it does, I'm afraid it will be worse.

There was no way, so he had to hold the container in one hand and the humanoid beast with a beautiful skin in the other, Lin followed the path he saw, avoiding the trajectory of those monsters towards him as much as possible, and advanced to the twentieth layer.

I can't take the weapon anymore, and I'm busy with both hands; Anyway, Fen still had one hand free to hold the gun. Fortunately, whether it is attack power or accuracy, this former demon lord is more trustworthy.
