Li Fan put the vest on the ground and began to undress.

He Changxin frowned, "What are you doing?" ”

Li Fan replied as a matter of course, "Wear a vest." ”

He wondered if his master was old and confused, and he let himself put on the vest just now, and now he asked himself what he was doing.

It's speechless.

He Changxin said angrily, "This is a prop, you just need to put him on your body, and he will automatically wear it on you." ”

Li Fan was in a daze, "Is that so?" ”

He put the vest on his body, and as he really said, after the weight-sensing vest was put on his body, a faint energy burst out, and after a while, it automatically fit his figure.

At the same time, the moment the vest was put on his body, Li Fan felt that all the strength of his body had disappeared and he had become an ordinary person. Also, he felt that he was carrying more than ten pounds of weight on his back.

It's an amazing feeling.

"Now that you're dressed, let's get started." He Changxin spoke, and then took the lead and ran out.

Li Fan hurriedly followed.

"Xiaofan, Master said that I will accompany you for a certain distance, and this is one of the journeys." He Changxin ran in front and said, "However, I can only accompany you for one day, and you need to insist on it yourself in the future." ”

Li Fan nodded, "Okay, Master." ”

Even if He Changxin doesn't say it, he will stick to it in the future.

He was fascinated by the feeling that he had reaped the huge benefits of a short workout just last night.

The two were running on the road, and at first, Li Fan didn't feel much pressure, but after running two kilometers, he began to breathe a little.

Strictly speaking, under the effect of the weight-sensitive vest, he is no different from an ordinary person now, and even inferior to an ordinary person.

His physical strength was completely suppressed in his body by the vest, and he added more than ten catties of weight, which was a huge burden for him.

After running another two kilometers, Li Fan was already red-faced, his breath was short, his chest was rising and falling violently, his heart was beating to the limit, and the blood in his whole body was already boiling.

He also faintly felt a slight pain in his five organs, which was very uncomfortable.

Anyone who has ever run has experienced this feeling, which is the body's ability to withstand the limit and cannot continue.

If you continue to run forcibly, it will cause great damage to the body and may be life-threatening.

"Why, it's only been four kilometers to become like this. Xiaofan, you can't do it. He Changxin teased.

Li Fan was a little unconvinced, gritted his teeth and insisted.

He was thinking, he was young and strong, how could he not be compared to the old guy Master.

Besides, men can't say no.

"Yo, still not convinced?" He Changxin just smiled, then didn't say anything anymore and continued to run forward.

Of course, Li Fan was not convinced, but he still couldn't help but glance at his master.

It stands to reason that He Changxin's age is already very old, and his strength has fallen so much, so there is pressure to run so far.

But he found that the other party had a relaxed expression, his face was not red or panting, and he was very calm, just like eating and drinking.

Li Fan couldn't help but tug at the corners of his mouth.

He felt offended.

The corners of He Changxin's mouth provoked a smile, "Boy, you can't." ”

Li Fan was speechless.

This contempt, simply.

It's not very hurtful, but it's extremely insulting.

Li Fan took a deep breath, the unconvinced psychology in his heart completely disappeared, and a reverent and sincere expression appeared on his face.

"Please teach me, Master!"

Only then did he realize that his master must have a knack, otherwise it would not be possible to be so light-hearted.

The speed of the two runs is not slow, but fast. Running four kilometers at this speed will make anyone out of breath.

And his master's face was as usual, and there must be a trick in this.

Therefore, he bowed his head directly and asked his master for advice.

"Hahaha, you're a clever kid." He Changxin was very satisfied with Li Fan's attitude, and he liked Li Fan talking to him like this.

Especially when he saw Li Fan's sincere expression, his heart was inexplicably relieved.

He smiled and said, "It's actually quite simple. Running is not as simple as it seems, you have to control the rhythm, not only the rhythm of the body, but also the rhythm of breathing, the whole body cooperates, so that it will be very easy to run. ”

He looked at Li Fan and said, "Try it." ”

Li Fan understood what his master meant immediately, and began to control the rhythm of his body, the rhythm of breathing, and the rhythm of his running.

It's easy to say and easy to understand, but it's extremely difficult to do. It's either the body's rhythm is out of order, it's breathing disorders, let alone the rhythm of running, it's a complete mess.

Li Fan's face suddenly turned red, and there was a huge pain in his internal organs, and his body felt as if it was about to explode.

He Changxin saw his state from Li Fan's face, and slowed down at the moment.

"Look at the teacher and run to the teacher's pace." He said.

Li Fanqiang endured the great pain in his internal organs and hurriedly looked over.

Honestly, he really wanted to stop now because he felt like something was going to be wrong with his body.

It's like I'm going to die.

"Don't get distracted!" He Chang was not smiling, his face was extremely solemn, and he let out a sigh.

He saw that Li Fan was at a critical juncture, and if he was distracted, it was very likely to cause great damage to his body.

In fact, he can ask Li Fan to stop now and try again when he recovers.

But instead of doing that, he just slowed down.

The first attempt is the most precious, and although Li Fan's state is dangerous, it is also a rare opportunity.

Because, if you find the trick later, the chances of getting into this state will be slim.

With He Changxin's soft drink, Li Fan suddenly came back to his senses.

"Follow me, teacher!" He Changxin drank lightly, "Breathe, breathe, breathe, breathe...."

He Changxin paused word by word, and every time he said a word, his body inhaled or exhaled, and his running breath was firm and powerful.

Li Fan followed, "Breathe, breathe, breathe..."

He followed He Changxin's movements, like a toddler, although it was very difficult, but he finally found the trick.

With the mastery of the rhythm, the pain of the internal organs has been relieved, and the body is not uncomfortable, and the whole person feels relieved.

"Yes, that's it!" He Changxin looked at Li Fan and was extremely excited.

Li Fan controlled the rhythm, his body became relaxed, and he swept away the fatigue just now.

At the same time, the nine stars in the starry sky seemed to sense something, and suddenly became dazzling, and the continuous power of the stars flowed through his body, making his body full of power.

Li Fan was overjoyed, running faster and faster, and in the end, a cloud of smoke passed by He Changxin's side!
