"Dragon's Blood?"

"That's right. Pen? Interesting? Pavilion wWw. ｂiquge。 info" Heilisha said, "This is one of the core secret techniques of our dragon clan, it is a kind of amplification secret technique in the Dragon Emperor Secret Technique, if you learn it for the first time, it can raise your body temperature and fight against the cold, which is most suitable for cultivation in extremely cold places, and you can get twice the result with half the effort." ”

Du Dian was slightly stunned, now he is no longer the person who knows nothing about the affairs of the dragon clan like before, the Dragon Emperor Secret Technique is the core secret technique above the Dragon Thorn Secret Technique, and only the patriarch and saint of the Dragon Clan are qualified to cultivate.

Among the dragons, the taboo of stealing secret techniques is extremely deep, and the punishment is severe, which is why Hathaway chose to use the means of private secret techniques to frame Helissa.

"You...... Isn't that a violation of the rules of the clan? With a hint of temptation and reminder in his peace of mind, Du Di said quietly.

Helissa said indifferently: "Anyway, in the eyes of those people, I have already passed on you privately, and now it is nothing to pass on you again, not to mention that my status as a saint has been deprived, and there is nothing that can continue to be deprived of them, unless it is my life." ”

"However, they won't kill me, even if I teach you the entire Dragon Emperor's secret technique, they won't kill me, let alone punish me, because the biggest punishment is to guard the wasteland."

Speaking of this, she stared at Du Dian and said, "I will pass on you, do you dare to learn?" ”

Du Dian looked at her deep eyes, suddenly smiled, and said: "Of course I dare, as long as you dare to pass on, I dare to learn, even if you don't pass on, if I am given the opportunity, I will also steal the learning." ”

Hearing this, a smile appeared on Hailisha's face and said, "I knew that you were very bold. ”

Dudian said: "Actually, it's not big enough. ”

Heilisha smiled: "As long as you don't say it, if I don't say it, no one will know, you just try not to show it outside, but if you have to do it, use it, and if something happens, I will bear it." ”

Du Dian nodded slightly, but secretly said in his heart: "As long as I survive this period of time, when my new magic is made, I don't need to bear anyone's punishment." ”

"Ready to get started." Helissa said: "You take off your coat and armor first, shiver your muscles to keep warm, and I will explain to you the principle of dragon blood technique." ”

Du Dian nodded slightly and did as he was told.

As soon as the armor was taken off, the cold air covered his body, and he couldn't help shivering.

"The key to cultivating the dragon blood technique lies in the word 'blood' in it." Hailisha spoke quickly but not impatiently, and said: "If you want to practice dragon blood art, you must first make your physique reach the level of an advanced hunter and learn to control the beating frequency of your heart, and then you can learn that with your current physique and control of your body, you can already exercise to control the beating frequency of your heart." ”

Du Di'an's body trembled slightly, and he said with a cold breath: "I will." ”

"Will you?" A hint of discoloration flashed in Helissa's eyes, although it was said that a high-level hunter could practice controlling the heart beating frequency, but this was for those geniuses who had set records in history, and for most ordinary people, even those whose physique had reached the advanced limit, they might not be able to learn to control the heart beating frequency, let alone cultivate the dragon blood technique.

"Since you can, first control your heartbeat and increase the frequency, three hundred beats per minute first." Helissa said.

Du Dian immediately knew what she was thinking, the faster her heart beats, the faster she pumps, and her body temperature will naturally rise. And the heart rate of 300 beats per minute will instantly overload the heart for ordinary people, causing heart failure and even myocardial infarction and death, but for him, it is not the limit of his endurance.

Thump! Thump!

He controlled his heartbeat to speed up rapidly, and with each beat, the blood flowing back swelled out and flowed into his body, causing the blood circulation throughout his body to be extremely fast, and a wave of heat slowly appeared in his body.

You must know that every fifteen to twenty times of a normal person's heartbeat, the body temperature will rise by one degree, and the heart rate of an ordinary person is 60 to 100 a minute, with Du Di'an's heart rate at the moment, if he is not suffering from iceblood, the body temperature will reach about 45 degrees.

However, at this moment, although he felt a trace of warmth, this warmth was tightly compressed by the cold near his heart, and the local body temperature of his heart reached about thirty-eight or nine degrees, and there was a sense of heat, but his hands and feet were far away from his heart, his nerves and blood vessels were relatively weak, and the blood transmission was slow, and he was still cold.

Especially near the shoulder of the left hand, the cold was biting, and half of the left body was shivering.

Helissa was a little closer to Du Di'an's chest, listened attentively, counted silently, a minute passed, Du Di'an's heart beat accurately three hundred times, no more, no less, this control was far more accurate than she thought!

And precision means having more spare power!

"Dragon's blood technique mainly uses the blood in the body, and the use of blood requires the use of the heart." Helissa said: "The strength of a person depends largely on the blood in the body, blood is the flow of energy in the body, when we are angry, we often feel the blood in the body boiling, red face, red ears, this is because the frequency of blood flow accelerated, rushed to the brain. ”

"At this time, I often feel that I have infinite strength, and I am more numb to the pain, and I can easily pick up things that I can't pick up in my normal state."

"So, to control the blood is to control the power."

Hailisha explained to Du Dian, and when he held on for another two minutes, he said: "Try another hundred improvements, if you feel that it is difficult, stop, the exercise of the heart is very dangerous and prone to accidents, so the cultivation of dragon blood must be supervised by someone, even if the cardiac arrest occurs, it can be rescued in time." ”

Du Dian nodded slightly, controlling the rate of his heartbeat to continue to increase.

Helissa stared at his chest, scars all over his fair skin, and although she had seen it once before, it was still a little shocking to see it again, and it was not difficult to guess what kind of torture and experience the teenager had endured.

Her eyes flickered slightly, her lips gently silently, a minute passed, and this time Du Di'an's heartbeat rate reached four hundred, and it was still accurate!

A hint of condensation flashed in her eyes, even if she was a high-level boundary, it would be very difficult to reach a heart rate of four hundred a minute, but for Du Dian, this was not his limit?

She glanced up at Du Dian, and saw that his expression was calm, but his breathing was a little rougher, and she was more confident in her guess, she did not continue to let Du Dian raise his heart and touch his limit, after all, he had not undergone exercise, and he was approaching the limit of his heartbeat, and his heart was unbearable.

"From now on, control the heart rate to decrease at a rate of ten beats per second, all the way down to twenty per minute!" Helissa said.

Dudian immediately did as he was told.

Soon, his heartbeat became slower and slower, twenty heartbeats per minute, which was also lower than that of ordinary people, but for him, it was far from the limit.

"Ten times a minute." Helissa said.

Dudian slowed his heartbeat again, and as the rate of his heartbeat slowed down, the chill around him grew heavier.

Helissa said: "Slowing down your heartbeat is not to suppress your heartbeat rate, but to lengthen your heartbeat rate, which helps to exercise your heart muscle, when your heartbeat rate is elongated, your heart will store more blood when pumping blood, and when it gushes out, the speed and volume of blood will increase, even when the heartbeat is ten per minute, the calories brought by it must be worth the effect of four hundred per minute!" ”

Dudian was slightly stunned.

Elongate your heartbeat? Exercising the heart muscle?

It was the first time he thought that the heart muscle could still be exercised.

However, according to Helissa, if you lengthen the heartbeat rate, you can indeed exercise the heart muscle, so that the amount of blood pumped every time the heart beats is greatly increased!

In this way, one beat is worth the pumping volume of an ordinary heartbeat of two to three times!
