The first thing Yue Zheng opened was the secret book of "Iron Body Gong" that Qin Lao said could suppress the abnormal changes in his body.

The secret book is not thick, and the content inside is easy to understand, and each page is a picture of the practice posture, supplemented by dense annotations. The practice concept of the entire Tantra is roughly to use 36 different movement postures, supplemented by important auxiliary methods such as strong blows and medicinal baths, so as to greatly strengthen the ability of the skin and flesh to resist blows.

Head, arms, elbows, knees, fists, palms, waists, body, legs...... Thirty-six postures cover almost the whole body of the human body, each of which is tempered with a different part of the body, and each movement must be combined with a unique breathing and luck method, so as to penetrate the cultivator's own internal breath tempering into the cultivator's skin membrane.

And the demon slayer who has cultivated to this point can even resist the musket fire of non-vital parts, and the defensive effect is extremely amazing.

It took nearly half an hour, and after thoroughly flipping through the secret book in his hand, Yue Zheng became more and more yearning in his heart, and then immediately concentrated and called up the long-lost auxiliary panel:

Name: Yue Zheng

Pneumatic power: 2.1

Physique: 2.0

Sensitivity: 2.0

Spiritual: 2.2

Skills:

[Intermediate Breathing Method (Beginner)], Effect: Strength +1.1, Physique +1, Agility +1, Spirit +1.2

【Iron Body Skill (Not Learned)】

[Remaining Mandate Points]: 6

"There it is!"

Finding that the words [Iron Body Gong] had been added to the panel, Yue Zheng's eyes suddenly lit up:

"Just read the secret book carefully, and the panel will recognize it?"

And then, Yue Zheng's heart moved, and he found something different in the column of Iron Body Gong:

That is, except for the unlearned annotations, their overall words are pale gray, and the plus sign representing one-click upgrade is not displayed at the end.

Yue Zheng tried repeatedly, but he couldn't assign the Heavenly Mandate Points to the Iron Body Gong.

"So...... Helpers don't help me learn directly? Sure enough, it's not that simple......"

Yue Zheng's brows furrowed, and his heart suddenly understood.

In the game, what kind of exercise cheats and other things are directly right-clicked, and the characters are naturally learned directly. However, he understands that what he is in now is the real world after all, and even if the auxiliary panel can directly improve the realm, I am afraid that at least he will have to rely on himself to get started first and basically learn this secret book.

"Getting Started, Getting Started ......"

The previous idea had basically come to naught, but Yue Zheng was not much disappointed, after all, the modifier's existing one-click upgrade ability was exaggerated enough. He read the words, and immediately flipped through the secret book in his hand, and soon found the basic entry standard of this iron body skill:

That is, as long as you can continuously and completely run the 36-style cultivation posture of the Iron Body Gong, you can be regarded as entering the hall.

"Try it!"

Looking at the posture essentials of the first few styles of the Iron Body Gong over and over again, and then knowing all the mantra essentials by heart, Yue Zheng jumped out of bed excitedly, first spread out the secret book on the bed, and then stood in front of the bed by himself, standing upright, feet together, palms together with his hands on his chest, and posing the starting posture of [Iron Body Gong].

Then Yue Zheng straightened his arms, slowly leaned back and bent from his waist, and touched the bottom of his palms like a human arch bridge. In this process, he adjusted the map several times, and the action posture was basically up to standard.

If according to his original physical fitness, he would not have to think about it for a moment if he wanted to complete such a posture, but the magical breathing method of this world has a very significant effect on physical fitness, that is, relying on the foundation of this body, Yue Zheng can easily achieve the first action in such a short period of time.

After Yue Zheng's posture was completely standard, with the coordination of breathing and the operation of internal breathing, after only a few minutes, he gradually felt a different heat sensation gradually emanating from the chest, abdomen and back of the waist, as if these two parts had been exercised in some way.

However, after holding the first posture for less than ten minutes, Yue Zheng was already sweating slightly on his forehead, feeling that this posture had reached the limit of his body's endurance. Then he flipped to the second page of the book, and then straightened up against the map, his arms buckled, his left leg stepped in, and his waist twisted and stretched as hard as he could, like a twisted flower.

It also took a long time to adjust the posture, and then he slowly found the feeling, his waist and arms began to heat up with this posture, and the flesh and skin seemed to be in an invisible exercise in the pulling.

Five minutes later, Yue Zheng was dripping, and the maintenance of this posture had reached its limit.

This is followed by the third action, the fourth...... Fifth ......

Nearly two hours later, when the ninth pose was carried out, Yue Zheng's head, chest, legs, arms and other parts were completely suspended from the ground, and his hands were touching his toes, making his whole person look like a ring.

Now Yue Zheng's eyes were hazy, sweating, and his body was emitting scorching heat like a furnace, as if he had reached the limit of his body's bearing, but he was only relying on the remaining trace of will.

"Ten ..... Four, three, two, one!"

With the last trace of strength, Yue Zheng, who had completely exhausted his physical strength, suddenly collapsed to the ground, gasping for breath like a bellows:

"Whew, Whew, Whew......"

I only felt that there was no place in my body that was not sore, and Yue Zheng was lying on the ground on all fours, gasping for breath. His whole body seemed to have been salvaged from the water, and a large area of sweat was clearly printed on the ground, which showed the great physical exertion in these two hours of cultivation.

"I didn't expect these movements to look so difficult, but it was so hard to cultivate continuously......"

Yue Zheng lay on the ground, his blank mind slowly regaining his thoughts.

The entry standard of "Iron Body Gong" is to practice the thirty-six postures coherently, and with his current physical strength, he can only complete a quarter of the level, and there is obviously still a long way to go.

Of course, on the other hand, Yue Zheng has just started this secret book, and there is obviously a lot of room for improvement in experience and skills.

With all kinds of thoughts turning in his heart, Yue Zheng slowly sat up, staring at his muscles that were now obviously congested and full of bulging feelings, and his brows were tightly locked.

According to Xu Liang's instructions before leaving, he knew that from tomorrow onwards, he would first have a month-long special training with the instructor who eliminated the demons, and after the training was passed, he would join the Eastern Brigade under the command of Deputy Lieutenant Lianghu and officially participate in the dangerous night duty mission.

With the endless out-of-control and alienation incidents in the dark night, as well as the death rate of more than one-fifth of the demon slayers, Yue Zheng has a great sense of crisis, and he is eager to master the two self-defense skills of "Iron Body Skill" and "Sky Splitting Knife" before this.

"According to the instructions in the secret book, if you want to start the iron body skill in the first stage of the breathing method, you need to practice hard for at least three or four months, while the second stage of the demon slayer only takes two months..... In other words, the level of breathing and physical strength has a significant effect on the efficiency of the cultivation of this secret book......"

Yue Zheng weighed it repeatedly and made up his mind:

"So let me try ....."

The next moment, he had already called up the auxiliary panel again, and then in the column of [Intermediate Breathing (Entry)], he clicked the plus sign!
