After two classes in the morning, after having lunch with a few rare roommates, Lin Yu found an excuse to get out and went into the school's grove.

The mechanical shield axe was too bulky to carry, but he carried both hydraulic gauntlets and smart glasses, and the Venom suit was always worn on his body.

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

【Hydraulic exoskeleton gauntlet】

[Grade] LV3: 128320/100000

[Introduction]: Hydraulic exoskeleton boxing gloves, compact structure, stable action, impact and vibration resistance, strong grip and explosion-proof performance, but slightly poor controllability, high requirements for processing precision and sealing, high cost.

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

——————————

The hydraulic exoskeleton gauntlet originally had more than 85,000 experience left, and the follow-up pneumatic exoskeleton video also gained more than 5,000 points, plus yesterday's limelight, which has continued to increase by more than 30,000 experience until now, and the upgrade demand is more than enough.

"Huh?"

However, when Lin Yuzheng was habitually preparing to click the upgrade button with his mind, the whole person was stunned for a moment.

The upgradeable button that pops up after reaching experience is gone.

"What's the situation, it won't reach the top at the third level, right?"

Lin Yu's face was a little unpleasant.

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

And he wasn't sure if this situation was an individual phenomenon or if all items could only be upgraded to level three, if all items could only be upgraded to level three, that would be fine, and if it was only the hydraulic gauntlet that could only be upgraded to level three, then it would be a big problem.

can only be fixed to level 3, which proves that it is only a level limit, and it is a big deal to make the initial item more perfect to increase the potential of the item in disguise.

But if it's an individual phenomenon...... That could mean that it's not the level of the item that is restricted, but the level of upgrade of the item, and it's likely that all items will only be up to the level of the hydraulic gauntlet.

"No, if you can only improve to this level, then what's the point of showing and collecting experience after level three, you can definitely upgrade, but I haven't found a way, or I can't improve it for the time being."

After forcing himself to calm down for a moment, Lin Yu came back to his senses and had to temporarily leave the matter of upgrading the hydraulic gauntlet.

It's useless to think about these now, so I can only slowly find a way, and for now, I'll finish upgrading things first.

The mechanical shield axe is not brought, and the experience gap required is quite large, at least tomorrow is enough, and the mechanical shield axe is already level three, I'm afraid it can't be upgraded for the time being - I hope it can't be upgraded.

The Venom suit is also level 3, and the experience requirement of 400,000 is even more far away, and the only thing that can be upgraded is the Xueba system.

Xueba system has experience income every day live broadcast, this time it may be that the new fan more or less attributed his 'genius' to the Xueba system, so the Xueba system has also gained a lot of experience, which can meet the upgrade needs.

Airplanes!

Lin Yu took off his smart glasses, and after his thoughts, the smart glasses shone with a dark blue circle of light from one side.

All the places where the blue circle of light crossed the smart glasses seemed to melt and turned into a wriggling pool of mercury, but surprisingly, the mercury did not fall from his hand, but instead formed a fluctuating ring of water around his palm.

"Is this going to change the carrier?"

Looking at the change after the aperture was drawn, Lin Yu frowned slightly, but he didn't regret it.

There is a level upgrade of the smart glasses Xueba system, only 500 points of experience, and it is easy to copy another one, which is not worth mentioning at all compared to the re-upgrade of the Xueba system.

Whether it's a shield axe, a fist gauntlet, or a venom suit, level 3 is almost a qualitative level, and the Xueba system, as the item with the highest demand for basic experience so far, will definitely not be far behind.

Soon, the entire smart glasses completely turned into a ball of mercury, and after the upgrade, the new attribute panel was revealed.

【Implantable Dream Learning Device】

[Grade] LV3: 1084/500000

[Introduction]: Implantable nanorobots, equipped with powerful learning assistant programs, connect to the central nervous system to perform retinal imaging, and at the same time, in the sleeping state, the auxiliary programs can regulate neurons to enter the lucid dreaming state.

[Evaluation]: Work harder than me? Tell you, I was studying when I was dreaming, so I asked you if you were afraid.

——————————

"Lucid dreaming?"

Lin Yu was really stunned this time.

From the very beginning when he met the anti-heaven scholar who 'learned in his dreams', he must be false if he said that he didn't envy, jealousy and hate, but he didn't expect that he would have a day when he would master this 'ability' by relying on black technology.

Of course, this is not the main reason why he is stunned, he is stunned because he has really learned the thing of lucid dreaming, and he will always have a little second thought in the second year of secondary school and after reading too many movies and novels.

Long before the tide of dark energy, there was indeed a group of people on the Internet who claimed to have mastered 'lucid dreaming', and it is indeed possible to achieve regular lucid dreaming outside of those nonsense.

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

Lucid dreaming is the ability to exercise and give psychological cues to yourself, to constantly recall dreams after waking up to deepen your ability to remember the content of dreams, and then set a 'trigger' for yourself with mental cues, usually specific actions and objects, so that you can think about 'whether you are dreaming' when you see these objects in your dream, and then realize that you are dreaming, and finally recover consciousness and think into a state of half-dreaming and half-awake.

There was once a fire movie called Inception that was filmed on this basis.,The male protagonist's spinning top is his 'trigger'.,Carry a spinning top with you.,The subconscious has been trained to the point where you want to subconsciously take it out and turn it around from time to time.,The spinning top is the reality when it falls.,If the top doesn't fall, it can make it realize that it's entered a dream.。

This is actually a very natural and egg-based 'ability', far less mysterious than in the movie, dreams are just made up by the brain, when dreaming, I feel very powerful and realistic, but after waking up, I really want to remember it is full of mistakes and omissions, and it is very vague, there is no meaning at all, and it is impossible to learn in dreams, it can only be said that it is just to escape reality by doing whatever you want in the dream, and the degree of truth is not clear, and the nature of brain supplement YY is similar.

When he accidentally came into contact with these on the Internet, he really tried this thing because of novelty, and even vaguely entered that state, but I don't know if it's because of unskillful reasons, there is no clear picture at all, it's similar to imagining with your eyes closed, plus the thoughts are complicated and difficult to control, and it's actually difficult to control the content of the 'dream', and then the matter is gone, after all, he is not so miserable that he wants to completely escape from reality, if you really want to 'do whatever you want', it is better to go to your mother to read this novel.
