The spindle-shaped sensory vortex is constantly rotating in Chen Mu's body. It is now almost twice as large as when it was first formed.

This was Chen Mu's thirty-third experiment with the sensations in his body. His experimental steps are divided into fine details. He made an extremely detailed and extremely detailed exploration of the characteristics of the fusiform sensory vortex at different rotation speeds.

Judging from the current results, he divided the rotation speed of the fusiform sensory vortex in his body into three stages. There are low speed stage, medium speed stage and high speed stage, and each stage is subdivided into five levels by him.

What he is currently experimenting with is the fifth level of the high-speed stage. At this speed, almost all the sensory filaments are mobilized, and hundreds of thousands of sensory filaments are shot out from his body and spread into the surrounding air. Affected, his six senses became sharper than ever before.

These sensory filaments extended to four point nine meters and then stopped. This is also the farthest distance that his perception can extend now. He has never been able to break through five meters. These invisible filaments of perception floated around his body, like tiny tentacles. They were extremely sensitive, and they could capture even the smallest fluctuation of perception in the distance.

This is the ultimate speed he can control. Judging from the results of his current experiments, the faster the fusiform sensory vortex spins, the more sensory filaments are ejected.

What will happen if you continue to increase your speed? He was a little hesitant. He didn't know if it would have any adverse effects. Any faster speed would be beyond his control.

He denied that it was his adventurous idea, but instead urged the fusiform whirlpool of perception to gradually slow down.

The extension range of the sensory filaments reached 4.9 meters and could no longer be extended. This problem has been bothering him. He has yet to find the factors that determine the perceived length of the filament. The rotation speed of the fusiform sensory vortex determines the number of sensory filaments ejected. The faster the speed, the greater the number of sensory filaments emitted. On the contrary, the less.

But what affects the perception of the extended length of the filament?

Unknowingly, the rotation speed of the spindle-shaped sensory vortex slowed down, and soon it approached the low-speed level. This is the slowest speed at which the fusiform sensory vortex spins in the spontaneous state. Under normal conditions, it will maintain this rotation speed.

Suddenly, Chen Mu realized that he had overlooked a very important issue. I have been speeding up the fusiform sensory vortex, but I have never thought of slowing it down.

Slowing down, what happens to the fusiform sensory vortex? Chen Mu became curious.

The fusiform sensory vortex quickly returned to its previous rotation speed, and Chen Mu began to control its rotation in reverse. Sure enough, it was feasible. Chen Mu was secretly happy, and its speed gradually slowed down.

Chen Mu did not dare to be careless and carefully experienced every change in the spindle-shaped sensory vortex.

The speed is getting slower and slower, and the number of scattered sensory filaments is also rapidly decreasing. In a short period of time, there are only about a hundred scattered sensory filaments left around Chen Mu's body. Chen Mu tried to control one of them, he wanted to see what changes happened.

He soon concluded that as the filaments of perception diminished, his control over them rapidly increased.

He tried to move the sensory filament forward. At this length, the sensory filament had reached its limit. The fusiform sensory vortex will give it a strong pull inward, thereby preventing it from extending forward.

However, this time, this sensory filament moved! It extended forward quickly, and Chen Mu did not feel the original pulling force.

Chen Mu was stunned and froze for a moment.

The out-of-control spindle-shaped sensory vortex suddenly returned to its original speed, the familiar pulling force suddenly appeared again, and the sensory filaments retracted to four point nine meters.

When Chen Mu came back to his senses, there was unconcealable ecstasy on his face. He was sure that at that moment, the sensory filament had definitely exceeded five meters!

It took a full ten minutes for him to regain his composure. He suppressed his excitement and tried his best to stay calm. He began to carefully control the fusiform sensory vortex to slow down, and then, the exact same situation as before appeared again.

Five meters! His perception range finally exceeded five meters! He finally fulfilled the requirements on the mysterious card. This has been a long time since he made the twelve cards of the simple water world.

Instead of relaxing, he continued the experiment.

Soon, he found a pattern. The slower the spindle-shaped sensory vortex rotates, the fewer sensory filaments it can emit, but the length that these sensory filaments can extend is also greatly increased. Moreover, Chen Mu also found that not only the extension length, but also other aspects of control of these sensory filaments were easier to control.

However, blindly slowing down the speed of the fusiform sensory vortex is also dangerous. When the speed gradually decreases and approaches a certain critical value, the spindle-shaped sensory vortex begins to show signs of instability. Chen Mu speculated that if the speed continued to decrease, the fusiform sensory vortex would likely collapse.

Chen Mu also came up with new data. The maximum length that his sensory thin line can extend is 6.2 meters, which is far beyond the five meters required in a simple water world.

It turns out it’s that simple! Chen Mu smiled bitterly, he had been trapped at this point for such a long time, but he just didn't expect it.

He seemed to feel that his understanding of perception suddenly improved to a higher level, and his control over perception became more complete. The spindle-shaped sensory vortex in the body also changed again. Its initial speed disappeared, but continued to fluctuate with the changes in Chen Mu's control.

Chen Mu controlled its rotation speed more freely, but every time it approached the high and low critical values, he felt a warning sign. It seems that the improvement in perception has also made his intuition sharper.

Breaking through five meters means that he can trigger the next level of the mysterious card. He didn't know what kind of surprise the mysterious card would bring to him? He couldn't help but look forward to it.

It's just that he didn't have a professional evaluation, so he didn't know exactly where his perception was.

Take out the mysterious card, tear off the camouflage film on it, and insert it into the meter on your wrist. Once again he entered the familiar world of simple water.

Without hesitation, he reduced the speed of the fusiform sensory vortex to the lowest point. Dozens of 6.2-meter sensory filaments were scattered around his body.

"Congratulations, your perception has exceeded five meters." The old and calm voice sounded next to Chen Mu's ears again.

"The swordfish challenge has not been completed yet, do you want to enter one round?" The second sentence made Chen Mu feel a little stupid. At this time, he also reminded himself that the swordfish challenge has not been completed yet. Could it be that the swordfish challenge is important? Or is the swordfish challenge gone once you move on to the next round?

He hesitated.

Will it advance to the next round? I insist on training hard every day and endure huge pain, isn't it just to see what the next round will be? Now, the opportunity was right in front of him, but it gave him another unexpected reminder. However, if you choose no, will there be some irreversible changes?

He didn't dare to be careless in every word of this old voice, or even in every word. This is the most important and intuitive clue provided by this mysterious card. Only by carefully analyzing the meaning contained in these words can he make a more accurate and more beneficial choice for himself.

After thinking for more than ten minutes, he decided to choose no.

What made him relieved was that, except for the disappearance of the old voice, the simple water world was still the same as before, without any difference.

After withdrawing from the simple water world, Chen Mu felt a sense of fear. If irreversible changes had just happened, he didn't know how much he would regret it. But thankfully, I was lucky this time and my bet was right!

Next, I am left with the swordfish challenge! Chen Mu was in high spirits, and his whole body seemed to be full of strength.

He temporarily put down all the work on hand, except for the unwavering aerobics and sensory exercises, and spent the rest of his time on the swordfish challenge. Fortunately, he had a swordfish training card, otherwise, he would have been seriously injured dozens of times by now. He still remembered the sharp pain like pins and needles.

By constantly running and dodging in swordfish training every day, Chen Mu made rapid progress. However, what he didn't expect was that perception played a key role!

The longer the sensing filaments are, the farther away the fluctuations can be felt. The more the sensing filaments are, the more sensitive one can be to changes in the surroundings.

Especially the second point is so important to him! While keeping the fusiform sensory vortex rotating at high speed, he could feel any subtle changes in the surrounding water flow. In normal times, although it can be felt, it is far less clear than in this situation.

The only problem now is how to maintain stable control of perception while running and dodging.

Could it be that these trainings in Simple Water World are actually related to each other? Sometimes Chen Mu would occasionally come up with this idea.

As long as the goal and method are found, it is not a very difficult problem for Chen Mu. He has enough grit and toughness to get it done.

After fifteen consecutive days of swordfish training, Chen Mu maintained control over his perception at all times, whether eating or doing other things.

He was very satisfied with the results. On the fifteenth day, his probability of completing swordfish training reached 75%. For such a complex challenge, any factor may play a decisive role. It is basically impossible for Chen Mu to achieve 100% success.

He is already very satisfied with this result.

After resting for a day and allowing his body's functions to return to their best condition, Chen Mu prepared to enter the simple water world for the swordfish challenge.

Before he could take out the mysterious card, suddenly, there was a knock on the door.
