After returning home, Shen Rui finally relaxed. Although the world outside was vast, it was not as comfortable as at home.
Then the practice was repeated step by step, and soon another week passed.
The time is Sunday, the eighth week after his rebirth.
Shen Rui was in the gym at home, taking a medicinal bath, with bubbles popping up in the light green bath water.
He closed his eyes. On top of his strong body, the skin was covered with a protective layer of particles, which was already integrated into one body, dense and seamless.
In the past, there were many gaps, but now they are leak-proof. The entire particle protective layer has become extremely strong.
It is not an exaggeration to describe it as "a needle cannot penetrate, and water cannot penetrate".
Moreover, these special particles are conscious and only allow gas molecules that are beneficial to the body to pass through for the body's ventilation. Secondly, the normal metabolism of the skin will not be affected, and sweat will be discharged as usual.
On the contrary, once it encounters poison from the outside, it will automatically close and not even a trace of gas will leak out.
It's just that Shen Rui has a feeling that his cultivation has reached a bottleneck. The special particles integrated into his skin have evolved to an extreme with the support of 160,000 physical training resources.
Nowadays, most of the nutrients in medicinal baths are rarely absorbed by specific particles, and more are used to maintain daily consumption.
Shen Rui opened his eyes, stretched out his palms, and with a thought, he saw that his palms immediately showed a silvery white color, and he could faintly feel a metallic texture.
According to the records in many books I have read, this should be a sign of the success of "iron skin"!
It just seems that the process is a little too mundane, but that's what real cultivation is.
The so-called "when everything falls into place" is nothing more than this.
He stood up from the bathtub and shook his whole body. All the water spray disappeared and his whole body became clean and refreshing, without even using a bath towel.
Shen Rui got dressed and decided to go to school. Now it was time to challenge the highest difficulty of the iron cage in order to verify whether the effect of his training was really "iron skin".
Luzhou No. 1 Middle School was still noisy on Sunday.
On the playground, there are still many people exercising hard. Even though they are facing the cold October wind, they are still sweating.
Shen Rui raised his eyes and glanced around, and found that most of them were freshmen, and most of them had just completed the particle protective layer on the skin of their limbs and moved towards the skin of the abdomen.
This can be seen from their cultivation location and surrounding conditions at this time.
If you have practiced to the chest skin and head, you should practice in a secluded place, not on the playground.
Nearly two months have passed since the start of school. It can be seen that for freshmen with ordinary qualifications and ordinary family backgrounds, it is difficult to practice physical skills.
And these people are the result of being eliminated through the first monthly exam and selecting the best from the best.
He couldn't help but feel sincere gratitude for the golden finger of the game "Qiu Bian". Without it, even if he worked hard, his progress and upper limit could only be on par with Tao Guang and others, or even worse than Wang Feng.
As for his physical fitness, it's not bad, but it's not very good either. His basic mental strength may be better, probably around 13 or 4.
With a hint of sigh, Shen Rui walked into the negative first floor of the office building, took the key given by Mr. Chen, opened the fence, and went all the way down to the "Training Room No. 6" on the negative third floor.
He opened the touch control console on the wall, thought for a while, and decided to be prudent. He first called up various mechanisms, set them to static firing mode, and tested their power individually.
"Crossbow, pass!"
"Poison smoke, pass!"
"Acid, pass!"
"Flame, pass!"
…
Shen Rui felt each mechanism, testing the protective effect of his skin's particle protective layer.
To his relief, he was almost immune to most physical and chemical attacks!
In the past technological era, these attacks would not be easily exempted even by the best protective clothing.
Especially when it comes to high temperatures and strong acids, even thickly armored units like tanks don't dare to resist.
But Shen Rui, a seemingly weak ordinary human being, has turned a blind eye under the blessing of special particles!
This is when he only has the first level of physical skills.
Of course, he believed that others at the same level of cultivation as him would not be able to do so easily.
Firstly, he has 63 points of charm, which can replenish void particles almost infinitely. Secondly, he has cultivated to the level of "iron skin and stone skin", and his protective power has increased dramatically.
After verification, Shen Rui already knew that the highest difficulty level for him was only limited by physical strength and eyesight.
However, he does not lack these two things.
So he decisively turned on the highest gear and got into the iron cage.
Crossbow arrows flew, bullets flew across the air, poisonous smoke filled the air, and from time to time there was strong acid.
But Shen Rui just took a leisurely stroll.
Although no one was watching, and no one was cheering or shocked, he didn't take it seriously because cultivation was for himself.
10 minutes later, a record appeared on the control screen on the wall.
"Shen Rui, a freshman at Level 15, is a freshman in high school. After 8 weeks of study, he passed the highest level test. His cultivation is the first level of perfect physical skills, and he has the exclusive title of 'Iron Skin and Stone Skin'."
After seeing the record flashing on the screen, Shen Rui was about to step out of the cage when the crossbow arrows flying in the sky and his 63 points of intelligence suddenly gave him an idea!
Running water does not rot!
Nothing remains the same, only change!
Crossbow arrows, poisonous smoke, and strong acid mist allowed him to see more mysteries.
He did not step out of the cage, nor did he dodge the attacks. The iron-clad layer of special particles around him was moving rapidly.
They sensed the host's thoughts, understood the other person's thoughts, and began to spin at high speed.
From top to bottom, from the inside out, those special particles were constantly exchanging positions. His whole body seemed to be forming a particle vortex or blowing up a storm barrier.
"This is a higher level of defense! It is stronger and more perfect than iron skin and stone skin!"
Shen Rui was excited, but his face was calm, as if he had done something insignificant.
He was able to cultivate to this point, and it was also a matter of course. Another person would never be able to do it.
Because they have no way to gather infinite void particles and form a flowing defense system at the first level of physical skills!
In modern warfare, rigid fixed defense will only be another Maginot Line of defense, and only mobile defense is the way to go.
After fifty-six days of practice, Shen Rui finally developed his own particle protective layer that no one had ever seen before!
After Shen Rui got excited, he calmed down the fluid particle defense layer around him and returned it to its previous fixed state.
It's very simple. Mobile defense does not move every day. It only moves when necessary. It is said to be as quiet as a virgin and move like thunder.
The consumption was so great that Shen Rui felt a hunger all over his body, and all the skin cells were asking for nutrients from the body.
The body's accumulation of first-level physical skills is not enough to support this kind of mobile defense.
Now is the time to train your muscles, improve your physique, and break through to the second level of physical skills!
