After two classes in the morning, he had lunch with several rare roommates. After that, Lin Yu found an excuse to get out of the school and head into the woods of the school.

The mechanical shield axe was too heavy to carry, but he carried the hydraulic armor and intelligent glasses with him, and the venom battle suit was always on him.

Since last night, the experience income of several equipment has not stopped. It is time to upgrade again.

[hydraulic exoskeleton Arm Armor]

[grade] LV3: 128320100000

[introduction]: the hydraulic exoskeleton boxing set is compact in structure, stable in movement, resistant to impact and vibration, strong in grasping force and explosion-proof performance, but slightly poor in controllability. It has high requirements for processing precision and sealing, and high cost.

Evaluation: it is a wild and strong man, please don't use it to embroider.

the hydraulic exoskeleton arm armor has more than 85000 experience, and the subsequent pneumatic exoskeleton video has also gained more than 5000 points. In addition, the popularity yesterday has increased more than 30000 experience, and the upgrading demand is more than enough.

"Well?"

However, when Lin Yuzheng was ready to use his mind to click the upgrade button, the whole person was stunned.

The original upgrade button that will pop up after the experience is gone.

"What's the situation? It won't reach the top at the third level?"

Lin Yu's face doesn't look good.

Although he had long suspected that there was a limit to the number of upgrades, and he had tried his best to make Xueba system improve himself in order to prevent this situation, but he was still a little difficult to accept when facing this situation.

And he is not sure whether this is an individual phenomenon or whether all items can only be upgraded to level 3. If all items can only be upgraded to level 3, that's fine. If only the hydraulic arm armor can only reach level 3, then the problem will be great.

They can only be fixed to level 3, which proves that it is only a level limit. If you make the initial items more perfect, you can improve the potential of items in disguise.

But if it's an individual phenomenon That may mean that the limit is not the level of items, but the upgrade level of items. It is likely that all items can only reach the level of hydraulic armor.

"No, if it can only be upgraded to this level, then what is the significance of the experience displayed and collected after level 3? It is certain that it can still be upgraded, but I can't find a way or can't improve for the time being."

Forced to calm down for a moment, Lin Yu regained his mind and had to leave the upgrading of the hydraulic armor temporarily.

It's useless to think about these things now. I can only find a way out slowly. I'd better upgrade the things first.

There is no mechanical shield axe, and there is a big gap in demand experience. At least it will be enough tomorrow. In addition, the mechanical shield axe is already level 3. I'm afraid it can't be upgraded temporarily. I hope it can't be upgraded.

The venom battle suit is also level 3. The experience requirement of 400000 is far away. The only thing that can be upgraded is Xueba system.

Xueba system has experience income every day. This time, it may be that new fans have more or less attributed his "genius" to Xueba system. Therefore, Xueba system has gained a lot of experience, which can meet the needs of upgrading.

Hum!

Lin Yu takes off his smart glasses, and after reading them, his glasses shine with a dark blue halo from one side.

All the places where the smart glasses were crossed by the dark blue diaphragm seemed to melt into a pool of creeping mercury, but surprisingly, the mercury didn't fall from his hand, instead, it formed a fluctuating water ring around his palm.

"Is this going to change the carrier?"

Looking at the change of the aperture, Lin Yu frowns slightly, but there is no regret.

The smart glasses Xueba system has been upgraded to 500 points of experience. It's easy to copy one out. Compared with the upgrade of Xueba system, it's not worth mentioning.

No matter whether it is shield axe, boxing set and venom battle suit, level 3 is almost a level of qualitative change. Xueba system, as the item with the highest demand for basic experience so far, is no worse.

Soon, the whole smart glasses completely turned into a ball of mercury. After upgrading, the brand-new property panel also showed up.

[implantable dream learning device]

[grade] LV3: 1084500000

[introduction]: the implantable nano robot is equipped with a powerful learning aid program, which connects the central nerve to perform retinal imaging, and at the same time, the auxiliary program can control the neurons to enter the awake dream state in the sleep state.

Evaluation: compare with me? I'll tell you, I always study when I dream. I'll ask you if I'm afraid.

"lucid dream?"

Lin Yu was really stunned this time.

From the very beginning, when he met the "learning in a dream" bully, he would say that he was not envious, envious and hateful. He did not expect that he would have to rely on black technology to master this "power".Of course, this is not the main reason for his stupidity. He is stupefied because he has really learned about lucid dreams. When he is a sophomore and has read too many movies and novels, he will always have some secondary thoughts.

There are indeed a group of people on the Internet before the dark energy tides that claim to have mastered lucid dreams, and the conventional lucid dreams do have the potential to come true, despite all the hype.

People will dream, even every night, but in the dream is basically hazy and fuzzy subconscious, and the dream content will be forgotten after waking up.

Lucid dream is to exercise and give psychological hints to yourself. After waking up, you can constantly recall dreams and deepen your ability to remember the contents of dreams. Then, you can set a trigger for yourself with mental hints, usually specific actions and objects. When you see these objects in your dream, you can think about whether you are dreaming, and then realize that you are dreaming and finally recover Conscious thinking enters the state of half dream and half awakening.

Once upon a time, a big fire movie called inception was shot on this basis. The male owner's top was his "trigger". He carried a top with him. His subconscious mind had been trained to the extent that he wanted to subconsciously take it out for a turn from time to time. When the top fell down, it was reality. If the top didn't fall, he could realize that he had entered the dream.

In fact, this is a very natural and ovoid "ability". It is far less mysterious than that shown in the movie. Dreams are only made up by the brain. When I dream, I think it is very powerful and lifelike. However, if I really want to remember after I wake up, it is full of mistakes and omissions, and it is very vague. It has no significance at all. What's more, it is impossible to learn in a dream. It can only be said that you can do whatever you like in the dream to escape from reality What's more, the true degree is not clear. It's similar to the brain tonic YY.

When he came across these things unexpectedly on the Internet, he really tried this thing because of his novelty, and even vaguely entered that state. But I don't know whether it is because of unskilled reasons that he doesn't even have a clear picture. It's similar to thinking with closed eyes. In addition, his mind is complicated and difficult to control. In fact, it's very difficult to control the content of "dream" After all, he was not so miserable that he wanted to escape from reality. If he really wanted to "do what he wanted", he might as well go and read a novel.
