According to the record in "Splitting Sky Knife", after practicing this knife technique that emphasizes speed and extreme speed, after practicing to the realm of Dacheng, because of the explosive force and knife speed, there will be a piercing explosion sound between full efforts, so it reminded Yue Zheng of this.

"That's right, 'Sky Splitting Knife' is an ordinary secret book, and it is not very difficult. As long as you study hard and practice hard, you can practice to Dacheng in a few years, and you can do it in the future. ”

After the trick just now, Xing Yuan seemed to have a better impression of Yue Zheng, and said lightly:

"Okay, let's talk about it now, and then the special training will begin. ”

As he spoke, Xing Yuan turned around and seemed to be looking for something, but Yue Zheng looked at the other party with emotion.

Sure enough, even if you are physically disabled, a demon slayer who can serve as a special training instructor is definitely not a good match. Yue Zheng could feel that Fang Cai's electric and flint battle was obviously not full of strength, which also fully illustrated the gap between the two sides.

Especially the Sky Splitting Knife that the other party used with the scabbard just now, the amazing power was thrilling, and it couldn't help but make him look forward to it even more and his eyes were hot.

Poof.

Yue Zheng was turning various thoughts, and the instructor Xing Yuan had already walked back and threw a bag of black heavy objects in front of him with a clatter:

"Put it on. ”

Yue Zheng squatted down and opened it to take a look, and found that it was a set of leather arm guards, vests, and leggings sewn with iron pieces sewn inside, which seemed to be some kind of weight-bearing equipment, and he only weighed it lightly, and found that it was a little difficult to pick it up with his current one-handed strength, and its weight was definitely not less than fifty kilograms.

"How can it be so heavy?"

With a bit of physical common sense, he really couldn't imagine that these inconspicuous vests, arm guards, and leggings would be so heavy, Yue Zheng couldn't help but be secretly surprised.

"This is a load-bearing equipment with black black iron, which has no other characteristics, that is, it is of high quality and high density, and the total weight is about 80 kilograms. ”

Xing Yuan said lightly:

"With the physical fitness of demon slayers, it is difficult to squeeze out the limit in just one month of special training, so a little special means are needed. For the rest of the month, I want you to wear them all the time except for sleep. ”

It's really a simple and rough way to exercise......

Yue Zheng grinned, didn't say anything, and immediately squatted down and took a lot of effort to put this set of equipment on his body.

Although his physical fitness was close to three times that of ordinary people, as soon as he put on this set of weight-bearing equipment weighing eighty kilograms, Yue Zheng immediately felt the heaviness and effort between his gestures, although it was not to the point of being unbearable, but the whole person seemed to be stuck in a quagmire.

didn't give Yue Zheng time to take a closer look, Xing Yuan took him to a black iron pillar again, and pointed:

"This is also an iron stake cast from Black Iron, and your first task is to use the Demon Slaying Knife in your hand to cut it off before it gets dark. ”

Cut off iron stakes with a knife?

Glancing at this iron pillar that was at least the thickness of his forearm, the green tendons on Yue Zheng's forehead couldn't help jumping.

But then he took a deep breath, clenched the demon slaying knife in his hand with both hands, and slashed out without any nonsense.

When the sparks splashed in all directions, under the huge anti-shock force, Yue Zheng's hands were numb, and the blade of the knife was raised high, leaving only a shallow white mark on the black iron pillar.

Yue Zheng forcibly suppressed the shock force from his arms, slashed out again, and then left another white mark on the iron pillar.

Bell Bell Bell Bell ——!

Then, Yue Zheng's muscles agitated, his green muscles burst out, and he mobilized the strength of his whole body to launch a ****-like continuous slash, and a series of sparks continued to burst out from the black iron pillar.

I don't know what material the Demon Slayer Knife is made of, like this fierce slashing hard object, the ordinary sword may have already been rolled and cracked, but the Demon Slaying Knife in his hand is still sharp.

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

However, under the weight of eighty kilograms, Yue Zheng's physical strength to be consumed for each movement was not only doubled, and in less than ten minutes under such a violent knife, his movements suddenly stopped, and then he was sweating profusely and gasping for breath.

And in his gaze, although the center of the black iron pillar in front of him was covered with dense white marks, it was not only 108,000 miles away from the cut required by the punishment.

And for this scene, Xing Yuan just stood by from afar, watching all this indifferently, without saying a word.

"No, it is impossible to cut off this iron pillar with brute force alone. ”

The tiger's mouth was numb and almost cracked, and his arms were even more sore, but Yue Zheng's heart was extremely calm:

"With my strength level, it's only possible to do it with every slash on the same mark, so the purpose of this training is to exercise precise control of strength?"

Probably thinking about the purpose of this training, Yue Zheng quickly sat down cross-legged, first began to run the breathing method, and quickly recovered his physical strength for a while.

And when Yue Zheng stood up again after ten minutes, he took a deep breath, and then stepped forward, slashing at one of the dozens of knife marks on the iron pillar, bursting out a cloud of sparks.

And when the spark flashed, a knife mark that was much clearer than the other white marks appeared.

That's it!

Finding the right way, Yue Zheng's eyes were sharp, he didn't slash like before, but tried his best to control the muscles of his body and the trajectory of the knife, striving to fall on the deepest trace of each path.

Of course, although the idea is clear, it is difficult to achieve this in the state of carrying 80 kilograms, but Yue Zheng, who has always had a strong sense of crisis in his heart, has a particularly urgent need for self-protection at this moment, and when this need is manifested in training, it is transformed into a will and determination far beyond ordinary people.

Bell, bell, bell!

For a while, Yue Zheng took his legs with his waist, belted his arms, and swung his knife with his arms. At first, he had at least three slashes on the same slash, but as he repeated the action of one slash, his control over the power and trajectory of the slash increased little by little, and the accuracy of the demon slashing knife was also increasing at a speed visible to the naked eye.

This is not Yue Zhengtian's genius, but in addition to his personal will and determination, the person who has cultivated to the second stage of the breathing method himself has far superior physical fitness and coordination ability, and he is actually just forcing out the original potential of his body now.

With Yue Zheng's movements, a very clear and obvious knife mark had already appeared on the iron pillar, and it was still deepening little by little. And looking at this scene, on the cold and hard face of Xing Yuan, who was standing on the side, the corners of his mouth couldn't help but hook:

"Lianghu, this old boy, I really found a good seedling this time......"
