Taking a deep breath, Chen Mu once again extended his perception five meters away.
In the blink of an eye, the simple water world disappeared, and the ever-present water pressure disappeared without a trace.
Chen Mu felt his whole body lighten, and he wasn't used to it.
All around him was a vast expanse of whiteness and fog, and he couldn't see his fingers in front of him.
Chen Mu was a little dumbfounded. Apart from the extremely dense white fog, he couldn't see anything else.
Chen Mu's mind stirred, and he vaguely captured something.
Almost unconsciously, he spurred on the perceptual vortex in his body, and the tendrils of perception immediately dispersed outside his body.
Suddenly, the formless white fog seemed to have been stimulated by something, and it started to change.
Like a living creature, it came alive all at once, surging and crashing, making what looked like a disorderly movement.
But, for some reason, Chen Mu always felt that the way the white fog moved seemed to imply some unknown regularity.
He simply closed his eyes and tried hard to capture the white fog.
The effect of his adjustment was quite obvious, as he immediately sensed that the white fog was divided into many tiny torrents, some of them colliding with each other, some of them twisting together, and some of them slowly penetrating each other..
"Test result: perceptual sensitivity index 35.
Suitable for the first level of training. "The hoarse old voice suddenly sounded, which also startled Chen Mu.
Just as the voice fell, the dense white fog around him was visibly thinning until it completely disappeared.
Chen Mu then found himself once again standing in the air.
Floating in front of him were five cards of different colors.
He was delighted that the thing he had been looking forward to had finally appeared.
Based on his previous experience, Chen Mu stretched out his finger and touched each card.
"Method of making the folding Yanbo card: perceptual sensitivity index required: 60."
"Tutorial on mid-grade token card theory: perceptual sensitivity index required: 70."
"Dynamic demonstration of the seven major energy compositions: perceptual sensitivity index required: 80."
"One breath perceptual training method: perceptual sensitivity index required: 90."
"Energy composition deduction model: conditions not met. Unable to trigger."
Looking at that string of information made Chen Mu's chest feel tight.
There wasn't a single one that he could obtain just then.
He noticed the information that popped up on each card. Except for the last one, the other four cards all mentioned the same concept: perceptual sensitivity index.
Chen Mu had never encountered that concept, and he had never encountered it in other books.
But, the result he had just gotten was that his perceptual sensitivity index was only a pitiful 35.
According to the information revealed by the cards, the perceptual sensitivity index was about ten.
He was still 25 points away from the folding Yanbo card, which had the lowest requirements. This was a gap of two and a half levels.
Chen Mu also noticed the last card, the "Energy Composition Deduction Model," which was the only one that didn't mention the perceptual sensitivity index, but still directly judged him to be inadequate.
"Elementary level perceptual sensitivity training commencing." The hoarse voice interrupted Chen Mu's thoughts.
Without waiting for Chen Mu to react, and without asking for his opinion, the mysterious card forced him into what was called elementary perceptual sensitivity training.
The scene in front of him changed again. Chen Mu was surrounded by many tadpole-like energy bodies that were swimming at high speed.
Their movements were very agile and hard to predict.
Just as he was feeling a little confused, a light screen suddenly popped up in front of him.
What was written on it was very simple. It was the so-called training rules.
Chen Mu needed to determine the number of energy bodies around him. The less time he took, the more points he would get.
Under such circumstances, using one's eyes was completely useless. One could only rely on perception.
After looking, Chen Mu decided to give it a try.
He closed his eyes and released his senses to the fullest.
By the time he came out of the mysterious card, three hours had already passed.
Although perceptual sensitivity training didn't consume much of his physical strength, it undoubtedly consumed a lot of his mind.
After only two hours of training, he felt a little overwhelmed. Not only was it strenuous to control the perception in his body, but his brain felt like it had been hollowed out, which was extremely uncomfortable.
After he came out, Chen Mu sank into deep thought.
It looked like that round of training was completely unfamiliar, but after careful investigation, it wasn't hard to find the connection between the two and the contents of the last round of training.
In the last round of the mysterious card, the core content had been to train perception, and this round was to train perceptual sensitivity.
The two clearly had a direct connection.
What Chen Mu was more interested in were the five cards, each of which represented one content.
Whether it was the middle-grade token card theory or the folding Yanbo card, they all made him salivate.
As for the knowledge of energy composition, it was a little too profound for him as he was then.
That had already touched upon the core and most essential content of the card system.
But the difficulty of that round was really a little high. Chen Mu couldn't help but smile bitterly.
He had been tortured to death in the training just then, with little effect.
He was really unfamiliar with that kind of alternative way of using perception.
He couldn't trigger any of those five cards just then.
Not only that, but the distance between him and them wasn't close, which meant that he wouldn't be able to trigger those five cards in the short term.
The only thing he could use just then was the reward from the swordfish challenge.
Although there weren't many specific techniques, that outline was still extremely valuable to him.
Just the few techniques it mentioned made him feel a little breathless.
The maker of that mysterious card was really a pedant, which was enough to make Chen Mu worship him.
For example, it mentioned how to maintain absolute calmness of perception in the midst of intense exercise, and such other techniques, which were all incredible.
What was most inconceivable to him was that it mentioned how to use the sensitivity of one's perception to test and find the most suitable technique for one to exert strength.
If Chen Mu had seen that outline earlier, he would have been able to easily complete the swordfish challenge long ago.
Compared to it, the little techniques Chen Mu had figured out in the swordfish training were so crude that even he felt a little embarrassed.
If he had to say what surprised Chen Mu the most, it would have been that he hadn't found the way to make a four-star card.
He had originally had high hopes for that mysterious card, hoping to find the method and knack for making a four-star fantasy card.
That way, he would be able to receive commissions for restoring four-star cards.
But he hadn't thought that there wouldn't be the slightest bit of technique for four-star cards.
That couldn't help but make Chen Mu feel a little disappointed.
Although the things in those five cards were good, they weren't what he could urgently use just then.
What he needed most just then was knowledge related to four-star cards.
Turning over the cards that Ning Yan had sent, the bitter smile on Chen Mu's face deepened.
Sure enough, there were twenty cards in the stack, eighteen of which were four-star cards, and only two were three-star cards.
Smiling bitterly, he had no choice but to do it, so he pulled out the two three-star cards.
Although the two three-star cards were exquisite, they weren't complicated for Chen Mu, especially since he had the analytical tool of token card theory.
The two cards were quickly repaired, and early the next morning, Chen Mu hurried to the library.
Since there wasn't any knowledge about four-star cards in the mysterious card, he would have to learn it through other means.
He was very clear about his situation. Although he had Madam Ning's plea, if he didn't show some value, his situation would only get worse and worse.
No one wanted to raise a person who could only eat rice. That was the same no matter where it was.
Up until then, he had used up a shocking number of materials, although there weren't any precious materials.
And once they were sure that he had no value, would the Ning family send him off so amiably?
That would be impossible!
Chen Mu had a thorough understanding of the cruelty of society.
It was a good thing that the books on cards in the library were very complete, and Chen Mu immediately threw himself into them.
During the time that Chen Mu was studying four-star cards, he had taken the time to make a shuttle card.
That shuttle card only used ordinary materials, but Chen Mu had used all the Token Theory he had learned to the extreme on that card.
The most direct result of that was that the power of the shuttle card wasn't much different from that of an ordinary three-star shuttle card, but it had a shocking effect in terms of firing frequency.
In theory, as long as the card artisan using it had strong enough perception, it could fire five energy shuttles in a second.
It could be imagined that it would be enough to sprinkle a rain of shuttles on the battlefield, with such a high density of attacks that the enemy wouldn't be able to dodge.
Compared to it, the tailless shuttle was as slow as an old ox dragging a broken cart.
He had already made great progress in controlling the tailless shuttle card, but he still needed 1.2 seconds to fire it.
Still, the deadly power of the tailless shuttle's one shot made it a frightening weapon.
Chen Mu named that shuttle card the "raining shuttles card," and then gave it to Lili for sale, with a price tag of 30 points.
There, he didn't have to worry about using the token card.
On the contrary, he was now demonstrating his value, which would be even more beneficial to his situation.
He didn't pay too much attention to the raining shuttles card.
His schedule was packed just then, and apart from going to the library to study the knowledge of four-star cards, he still had to go through that perceptual sensitivity training every day.
As for perceptual training and the exercise gymnastics, they were unshakable.
His packed schedule didn't give him any time to pay attention to anything else.
