After two classes in the morning, Lin Yu found an excuse to escape and went into the grove of the school after lunch with a few rare roommates.

The mechanical shield axe is too bulky to carry, but he carries both hydraulic arm armor and smart glasses with him, and the Venom battle suit is always worn on his body.

Since last night, I have never stopped earning my experience with several equipment. It is time to upgrade again.

——————————

【Hydraulic Exoskeleton Arm Armor】

【Level】LV3:128320/100000

【Introduction】: Hydraulic exoskeleton gloves have compact structure, stable movements, impact and vibration resistance, strong snatching force and explosion-proof performance, but slightly poor controllability, high requirements for processing precision and sealing, and high cost.

[Evaluation]: It is a wild and strong man, please do not use it to embroider.

——————————

The hydraulic exoskeleton arm armor originally had more than 85,000 experience left, and the subsequent aerodynamic exoskeleton videos also obtained more than 5,000 points. In addition, they were in the limelight yesterday, and have continued to increase their experience so far, and the upgrade needs are more than 30,000.

"Um?"

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

The original upgradeable button that will appear after reaching experience is gone.

"What's the situation? You won't be able to reach the top level three?"

Lin Yu's face looked a little bad.

Although he had long suspected that the number of upgrades was limited and he had tried to get a school-to-school system to improve himself in order to prevent this situation, he still felt a little difficult to accept when facing this situation.

And he was not sure whether this situation was an individual phenomenon or that all items could only be upgraded to level 3. If all items could only be upgraded to level 3, that would be fine. If only hydraulic arm armor could only reach level 3, the problem would be great.

All can only be upgraded to level 3, which proves that it is only a level limit. At most, you can improve the initial item by making it more perfectly, and you can improve the potential of the item in disguise.

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

"No, if I can only upgrade to this level, what's the point of the experience displayed and collected after level 3? I will definitely be able to upgrade it. 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 to his senses and had to temporarily abandon the upgrade of the hydraulic arm armor.

Now that these are useless, I can only find a solution slowly. Now I will upgrade the things first.

The mechanical shield axe was not brought, and the experience gap required is quite large, at least it will be enough tomorrow. In addition, the mechanical shield axe is already level 3, so I am afraid it cannot be upgraded for the time being - I hope it cannot be upgraded.

The Venom Battle Suit is also level 3, and the experience requirement of 400,000 is even more endless. The only thing that can be upgraded is the academic master system.

The Xueba System has experience income every day. This time, the new fans may have more or less attributed his "genius" to the Xueba System. Therefore, the Xueba System also gained a lot of experience, which has barely met the upgrade needs.

Buzz!

Lin Yu took off his smart glasses, and after chanting, his smart glasses shone with a faint blue aperture from one side.

All the places where the smart glasses were streaked by the dark blue aperture seemed to melt and turned into a pool of squirming mercury, but surprisingly, the mercury did not fall from his hands, but instead formed a wavy water ring around his palm.

"Is this going to change the vector?"

Looking at the changes after the aperture passed, Lin Yu frowned slightly, but there was nothing regrettable.

The smart glasses academic master system can be upgraded to one level, with only 500 points of experience. It is also easy to copy one more, and it is not worth mentioning compared to the second upgrade of the academic master system.

Whether it is the shield axe, fist gloves and venom war suit, the third level is almost at the same level of qualitative change. The academic system, as the item with the highest basic experience needs so far, will definitely not be much worse.

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

【Implantable Dream Learning Device】

【Level】LV3:1084/500000

【Introduction】: The implantable nanorobot is equipped with a powerful learning auxiliary program, which connects the central nerve to perform retinal imaging. At the same time, the auxiliary program can regulate the neurons into the lucid dream state.

[Evaluation]: Compare hard work with me? Tell you that I am learning when I dream, so I ask if you are afraid.

——————————

"Luke dream?"

Lin Yu was really stunned this time.

From the beginning when he met the genius who was "learning in dreams", he would say that he would not envy, jealousy and hate, which would be fake. He didn't expect that he would have a day to master this kind of "superpower" 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 lucid dream. He is a middle-aged man and has read too many movie novels, so he always has a middle-aged man.

There was indeed a group of people on the Internet long before the Dark Energy Tide that were allegedly mastered "lucid dreams", and conventional lucid dreams that were not allowed to be realized.

People will dream, or even dream every night, but in the dream, they are basically a vague subconscious mind, and the content of the dream will be forgotten after waking up.

Hurricane dreams are about exercising and giving yourself psychological hints. After waking up, you constantly recall your dreams and deepen your ability to remember the content of your dreams. Then you set a "trigger" for yourself with your own psychological hints. Usually, it is specific actions and objects, which can make you think about "whether you are dreaming" when you see these objects in your dreams, and then realize that you are dreaming, and finally restore your consciousness and thinking to enter a half-dream and half-awake state.

There was once a popular movie called Inception. The male protagonist's gyro is his "trigger". He carries a gyro with him. The subconscious mind has been trained to the point where he wants to take it out and turn it. The gyro is falling down is reality. If the gyro doesn't fall down, it can make him realize that he has entered a dream.

This is actually a very unique "power". It is far less mysterious than it is in the movie. Dreams are just made up for imagination. When dreaming, I feel very powerful and realistic. But when I wake up, I really miss it, and it is very vague. It is meaningless and even more impossible to learn in the dream. It can only be said that I am just trying to escape reality in the dream. The reality is not clear, which is similar to that of the YY.

When he accidentally came across these things online, he tried this thing because of novelty, and even entered that state in a vague way. But I don’t know if it was because of his unskilledness that he didn’t even have a clear picture at all, just like he imagined with his eyes closed. In addition, his thoughts were complicated and difficult to control, and it was actually difficult to control the content of the ‘dream’. Later, the matter was left unresolved. After all, he was not so miserable that he wanted to completely escape from reality. If he really wanted to do whatever he wanted, it would be better to go to read a novel by my mother.
Chapter completed!
