With Han Feng's eyesight, he naturally saw all this clearly, the vibration of the silver needle was not caused by Hua Lao's hand shaking, but completely trembling by himself.

Internal force!

Han Feng immediately understood the meaning of the so-called "Qi Needle", and the "Qi" mentioned here must refer to internal force.

Through the silver needle, the internal force can be transmitted to the other party's body?

Han Feng hadn't thought about this problem before, but now that he thought about it, he suddenly felt that it was completely possible, since the internal force could be sent out, it could naturally be transmitted through the silver needle.

Although Han Feng has understood the essence of internal force, he still has no experience in the use of internal force, and he still has a lot to learn in this aspect.

Thinking like this, Han Feng said: "Old Hua, lend me a needle, and I'll try it." ”

Hua Lao handed him the silver needle in his hand, a smile appeared on his face, he wanted to see how far Han Feng could go.

Han Feng took the silver needle, and also learned the action of Hua Lao holding the needle, pinching it with his index finger and thumb.

He used the method of releasing the internal force to slowly concentrate the internal force in his body on his right index finger and thumb.

A minute passed, and there was no movement at all from the silver needle.

Five minutes passed, still silently unmoving.

Han Feng's brows furrowed, thinking about what he had done wrong.

Hua Lao stood aside, smiling and touching his beard, as if he had expected this to happen.

However, what happened next surprised him!

"Woohoo!"

The silver needle in Han Feng's hand suddenly shook rapidly with a great amplitude, like a group of snakes dancing wildly, and the sound of a breach could be faintly heard!

Han Feng was obviously caught off guard by this situation, and hurriedly stopped transporting internal force. The silver needle still wobbled for a while before stopping.

Hua Lao asked movingly, "Han Feng Xiaoyou, how did you do this?"

"Uh...... I just focused my internal strength on my index finger and thumb...... "Actually, Han Feng didn't explain it well, and he didn't figure out why this happened. Because he did the same before, he divided the internal force into two strands, which were transmitted from the index finger and thumb to the silver needle, but at the beginning, the silver needle did not have any reaction, so Han Feng constantly changed the strength and circulation of his internal force, when he converted the internal force into a spiral internal force, and controlled the strength of the two internal forces in a certain proportion, there was a strange situation just now.

Hua Lao was shocked and a little excited at the moment.

Han Feng has a different talent. Unexpectedly, without anyone looking for it, he was able to successfully transmit the internal force to the silver needle accurately by just relying on his own groping, which made Hua Lao feel very shocked. Because in order to achieve this, it is not only necessary to have internal force, but also to have sufficient precise control of internal force, and it is already a very valuable thing for a person who practices martial arts to be able to train internal force to the extent that he can release it in his lifetime. The vast majority of people have practiced martial arts for a lifetime, but they can only achieve the effect of strengthening their bodies. Being able to achieve the external release of internal forces is already a kind of quite precise control of internal forces. People who don't have a certain amount of talent can't reach this level. And if you want to conduct the internal force to the specified utensils, such as the silver needle, the difficulty is increased not by a little bit, but by several times!

I think that at the beginning, Hua Lao was praised as a martial arts wizard by his master since he was a child, and he had already achieved internal strength before the age of twenty, and then after five years of diligent study and hard training, under the careful teaching of his master. He successfully transmitted the internal force to the silver needle, and Hua Lao still remembers the excitement of successfully making the silver needle shake a few times with the internal force alone.

And the reason why Hua Lao is excited is because talents like Han Feng are really rare and unattainable!

At the beginning, his master was lucky, he found Hua Lao when he was a child in his village, and began to cultivate him carefully since he was a child, and finally Hua Lao had his current achievements, and his master also completed the last mission of the master, and successfully passed on the Huamen medical skills.

And Hua Lao is not as lucky as his master, he has been looking for his ideal apprentice for more than 30 years, but he has not been able to follow his wish, considering that he is old, he may not be able to wait for that day, so he retreated and accepted three registered disciples to teach medical skills. However, the qualifications of these apprentices are limited, and for more than ten years, only one apprentice has barely achieved the level of "using qi to control the needle", and this apprentice is Zhang Junyu, the current president of the "Chinese Association of Traditional Chinese Medicine". And Zhao Dong is not even his registered disciple, he has only occasionally instructed him a few times in the past.

Hua Lao has been looking for and paying attention to some young talents with good qualifications over the years, and he plans to find a suitable apprentice to teach Huamen medicine as much as possible. At his age, there was no time left to train an apprentice from an early age. This time, I heard Zhao Dong say that there is such a candidate, that is, Han Feng, he said that this young man not only has a good internal force, but also seems to have reached a fairly precise degree of control over the internal force, and can concentrate the internal force on the entire palm. On the one hand, Zhao Dong was worried that Han Feng would go down the wrong path and wanted Hua Lao to help take a look, and on the other hand, he didn't mean to recommend young talents to him.

******

It just so happened that Beijing was going to hold a traditional Chinese medicine exchange meeting, and his apprentice Zhang Junyu invited him to participate in this exchange meeting as a guest. But when he heard about Han Feng, he decided to go to Beijing and meet the young man.

The situation of the meeting can be imagined, Han Feng's performance surprised Hua Lao quite a lot, it is no exaggeration to say that Han Feng is the most talented person in martial arts he has ever seen, no, including the one his master has ever seen!

He was able to create a set of actions that were conducive to the generation of internal forces by himself just by relying on the classic movements of his predecessors. Moreover, after learning about the method of breathing and the effect of the mind on the internal force, he actually created the corresponding exercises by himself in a short period of time! The most unbelievable thing is that this set of exercises can really work, and the effect is quite remarkable, so remarkable that it is unacceptable.

By this time, Hua Lao had already secretly made up his mind in his heart, he had accepted this apprentice! God opened his eyes and took the initiative to send such an apprentice to the door, how could he live up to God's kindness?

To be able to meet such a genius in his old age, Hua Lao is very pleased!

And now, Han Feng, who constantly surprises and surprises him, once again makes him feel like he has been hit by happiness!

Han Feng didn't notice Hua Lao's expression, he was wondering why the silver needle in his hand suddenly trembled so violently, from extremely static to extremely moving, the jump was a little too huge, right?

For unknown things, Han Feng has the momentum to find the root cause. So, he mobilized the internal force in his body again, converted it into spiral energy, and concentrated it towards his right hand.

The first time, without success, the silver needle did not respond in the slightest.

Han Feng began to slowly adjust the ratio of the strength of the two internal forces, and recorded the data of each time in his brain.

The second time, it still didn't work out.

Third ......

"Woohoo-""

The silver needle danced violently with a huge amplitude again, and Han Feng succeeded! Sure enough, it had something to do with the ratio of strength!

Han Feng suppressed the joy in his heart and continued to experiment, because the situation of the silver needle in his hand, the amplitude of the silver needle was very different from the situation just now, since Hua Lao could do it to that extent, theoretically speaking, he could also do it, but the way was wrong.

Han Feng directly observed the amplitude of the silver needle with his eyes, and then after almost conversion, it became a specific value and recorded it in his brain, and then he adjusted the strength of the internal force, the speed of circulation and other factors, and used scientific measurement methods to conduct experiments.

The amplitude of the silver needle in Han Feng's hand became smaller and smaller, and the two eyes of Hua Lao became wider and wider.

Hua Lao didn't dare to make any sound during the whole process, he was afraid of disturbing Han Feng's exploration process.

"Almost. ”

In the end, Han Feng finally adjusted the amplitude of the silver needle to the same situation as Hua Lao.

Hua Lao said excitedly: "Han Feng Xiaoyou, you ...... Is...... What a ......."

After talking for a long time, Hua Lao suddenly found that he couldn't find any words to describe the feeling in his heart at the moment, because Han Feng's performance was too ...... It's inhuman.

"I didn't expect that the internal force could achieve this effect, the ancients were really smart!" Han Feng sighed, "It is indeed not easy to make two internal forces act on the silver needle and make it resonate." ”

Through this period of exploration and experimentation, Han Feng has completely figured out what is going on, and from this point of view, it has also proved that the internal force is also a mechanical pulse, which belongs to energy fluctuations.
