Early the next morning, Wang Yu went to the park as usual to continue his studies.

Although he spent a lot of effort studying the black beads last night, it didn't affect his rest, and he was in good spirits and full state at this time.

He had a faint sense of what kind of black bead it was.

But it was only a little feeling, he didn't fully understand how the black bead was formed, but he felt a feeling from it.

The "Evil Soul" who once saved his life!

The guy who claimed to be the original owner of the Seven Evils and had no respect for the god of rebirth, was the one who talked about him in the realm outside of time and space!

This black bead, the breath exuding from it, is exactly the same as that guy! There is a cold in the mystery, there is no sense of heat, and it is so cold that it makes people tremble.

When Wang Yu tried to control the bead, he found that he could not control the flow of soul power in the bead, as if it was not his thing.

After studying it for most of the night, he still didn't understand how and when the black bead was formed, and how to use it.

But on the other hand, he vaguely understood why he was able to clear the Divine Breath Secret and return to this world by himself, it seems that it is because of this black bead, the soul density contained in it is so high, and the soul power will definitely not be weak, maybe in the critical moment, it is by relying on it to get through the difficulties.

And the fat man's soul weighing technique also seems to be flawed, at least the weight of the soul in this black bead could not be measured when weighing.

In the end, he couldn't come to a conclusion, so he had to give up for the time being, and changed to the method of cultivating souls, trying to cultivate his soul. As a result, in the morning, his soul, which was originally only the size of a ping-pong ball, actually rose back to the size of a fist!

It seems that soul cultivation is still effective.

When he arrived at the park, Wang Yu waited for more than ten minutes as usual before waiting for the old man, and when they arrived at the old place together, Wang Yu put on a posture, and according to the old man's instructions, first knotted his hands and legs, and then knotted his torso.

After the crackling sound, the old man sighed, "My old man really regrets taking you as a student. ”

Wang Yu only felt refreshed, and his whole body seemed to be inexhaustible. Hearing the old man's words, he couldn't help but be stunned: "Why? ”

The old man said with a strange expression: "Originally, I expected that you would be able to use up your month's learning process by learning the whole process, but you have actually mastered the torso section today...... Alas, forget it, it's the head of the knot, go on! ”

The skull, which includes all the bones from the upper part of the neck to the entire head. In a way, this part is the most important of all the sections, and for no other reason, if this part of the section is not done well, it will bring great dangers.

One is not good, which bone is misplaced when the joint is through, and the skull is dislocated, it is not something that can be solved by pressing it casually, and it will even affect the skull.

Therefore, when the old man taught, although he knew that Wang Yu was talented, he still did not dare to teach all the content at once, and divided this part into several paragraphs, and asked Wang Yu to fully grasp the previous part before starting the next part.

In his mind, Wang Yu was only in his teens after all, young and vigorous, and curious, if he rashly made a head joint, it would be bad to cause danger.

Wang Yu walked through the ghost gate in the rebirth world, and now he is more "afraid of death" than anyone else, and he does not urge the old man to teach all the content, but only listens obediently.

This unhurried and impatient attitude made the old man a little impressed. If someone else were different, they might think that he was deliberately delaying the teaching time! This kid, good!

The biggest difference between the head joint and the rest of the body is that it is not designed to give you more strength, speed or muscle response, but to make you more agile.

For anyone's body to respond to external stimuli, it needs to be judged by the nerves of the head. The function of the head joint is to shorten the time for nervous judgment and enable people to respond more quickly to external stimuli.

Normally, a person's reaction time is in the range of more than 0.1 second to less than 0.7 seconds. If the reaction is slow, it may be higher than 0.7 seconds, and if it is particularly slow, it may even reach one or two seconds, or even three or four seconds, commonly known as "hindsight". However, the fast reaction will only approach the former, and cannot exceed the "lower limit of reaction speed" of 0.1 second.

Of course, this is just normal people, professionally trained is another matter.

And the head joint belongs to the category of this "professional training".

"Come, now to enhance your impression, the stone over there, you can pick up a random piece and smash me." The old man first had a theoretical education with Wang Yu, and then walked to a position about three meters away from Wang Yu, standing with his feet fixed and his back to the lotus pond, looking calm and relaxed.

"Oh." Wang Yu turned around and looked at it, picked up a ping-pong-sized stone from the ground, and checked it, it was only a few taels, lightweight.

He raised his head, looked intently, and slammed his arm, and the stone came out of his hand, smashing directly into the old man!

The old man easily tilted his head and avoided it in an instant.

Thump!

The stone fell into the pond and caused a ripple.

"Push harder!" The old man is dissatisfied, this kid is obviously merciful, the stone shoots and knows that the strength is insufficient, even if he really has the same reaction speed as the average old man, he can avoid it, "When I am an old man, you will kill your father and the enemy!" ”

"This ...... Not quite right? Wang Yu was a little hesitant. After all, the other party is an old man, and he also taught him good things, what should I do if he is injured?

"I said, are you looking down on my old man or what?" The old man was displeased, "I'll let you smash it with all your might, and if you hit my old man, you are a great kid!" ”

"Okay...... Wang Yu had no choice but to pick up a stone of about the same size again.

Then take a deep breath and tense all the muscles around your body.

"Ho!" Wang Yu shouted violently, swept a full moon with his right arm, and threw the stone out violently!

Call!

The stone had a sharp whistling sound, so fast that his eyes couldn't keep up, and in an instant he had reached the door of the old man's face!

Syllable!

The stone hit the old man in the forehead, then bounced off and fell several meters away!

"Ouch!" The old man covered his forehead and jumped up, "You kid! ”

"Ah, old man, why don't you avoid ......" Wang Yu was startled, "Didn't you say you could avoid it......"

"Ahem, my old man wasn't ready all of a sudden, and he missed......" The old man rubbed his forehead and coughed dryly, a little embarrassed. Originally, he thought that this kid's punch was about 600 catties of strength, and the speed of the stone thrown should be within the range that he could easily avoid, but he didn't know that the speed of this blow was so fast that he couldn't react!

Wang Yu was a little worried at first, but after seeing that the old man took it away, there was only a little red mark on his forehead, and he couldn't help but be surprised.

The strength of this stone just now, even if it hits a cow if it is thrown out, I am afraid that it will be able to break its head and bleed, this old man's head is actually fine! Made of iron? So hard!

"See, I just now is the reaction speed of ordinary people." The old man insisted on a serious authentic way, "In the case of no knots, the speed of the stone is too fast, even if it is me, it is difficult to avoid it." ”

After speaking, the old man's head shook slightly, and the clicking sound rose instantly!

Wang Yu's eyes couldn't help but widen.

With his current eyesight, he can not only clearly capture the traces of the shaking of the old man's skull, but also determine which bone moves first and which bone moves later.

After a while, the festival was completed, and the old man's eyes lit up, and he shouted, "Do it again!" ”

Wang Yu turned around and picked up another stone, shook it in his hand, and looked at the old man.

And then—

Call!

The stone screeched and shot at the old man's door!

The old man's pupils contracted instantly, and his head tilted to the left almost the moment the stone was shot.

Wang Yu couldn't help but be moved.

This old man's reaction speed has really improved a lot compared to just now!

Before the thought was finished, there was a sudden "pop", and it sounded crisply.

Wang Yu was petrified in an instant.

The stone hit the corner of the old man's right eyebrow and bounced off!

"Damn!"

The old man covered the corners of his eyebrows and jumped up, bursting out in pain.

I still haven't been able to dodge, it's really embarrassing now, I just said a lot of things, and I actually came here!

"Old man, you...... Are you okay? Wang Yu ran over nervously.

"No, no, no, nothing!" The old man endured the pain in his brow and let go of the hand he was holding, "What's the matter with your kid's strength?" ”

"Uh, is there a problem?" Wang Yu didn't understand it all of a sudden.

"Absolutely!" The red mark on the corner of the old man's eyebrows was a little obvious, he thought about it, squatted down with a horse step, and leaned forward with his right hand, "Come, concentrate all your strength and punch!" ”

As soon as Wang Yu heard it, he knew that he was going to test his fist strength again, although he was puzzled, he still followed the order, "Hey", and punched out.

Strike!

The fist hit the palm, which was comparable to hitting a sandbag, and the old man's face changed instantly, and the palm of the hand that was hit shrank more than ten centimeters backwards!

Wang Yu was stunned.

This time, the distance of his palm seemed to be a little farther than yesterday.

"How is this possible! How can your strength grow so much in one day! The old man shouted in disbelief, "This punch has at least more than eight hundred catties of power!" ”

Wang Yu's mouth opened wide, and his jaw almost didn't fall.

Eight hundred pounds!

Yesterday morning, when the old man tested his strength, he said that he punched more than 600 catties, and now it has only been a day, and it has become 800 catties! Even if there is an error in the hand test, it will not be so large!

A thought flashed through him.

In the realm outside of that time and space, the guy who claimed to be the Extremely Evil Soul said that his physique became stronger because he benefited from the "Golden Evil" in the Seven Evils, could it be that this enhancement process is not over yet?

"Because your soul is now barely able to withstand the power of my Seven Evil Souls, your material storage, that is, your body, has begun to gradually merge with the golden evil qi in the past few days."

At that time, the meaning of that guy's words seemed that he Wang Yu was just starting to merge with Jin Sha, and logically this process should continue for a while, and it is still going on, as for when it will end, Wang Yu is not clear.

But of course, it is impossible to tell others about these things, Wang Yu came back to his senses, scratched his head and said: "I don't know what's going on, could it be that your old man made a mistake?" ”

The old man had never seen this kind of phenomenon, and for a while, he was a little unsure of it, and frowned: "Could it really be that I made a mistake?" ”

Wang Yu saw that he didn't pursue it anymore, and quietly breathed a sigh of relief.

It seems that in the future, you have to collect some points, otherwise this old man will be suspicious, and it will be bad if he gets into trouble.

"Forget it, although something went wrong just now, you should also be able to see that there is a significant difference in my old man's reaction speed before and after the head joint!" The old man didn't dwell on this matter anymore, "So the importance of the head joint, you kid should probably understand, come, let's start the formal head joint practice!" ”
