It was quiet in the attic, except for a white-haired old man with a wrinkled face, about eighty years old, dozing there on the chair next to the door.

Although this man looked senile, like an ordinary old man, with no sign of having practiced martial arts, Mu Han did not look down upon him in the slightest.[]

There are hidden dragons and crouching tigers in the Mu family. Some powerful people are fully capable of concealing their own aura. This old man can be sent by the Mu family to guard the Zangfeng Pavilion. He is definitely not an easy person.

"senior."

Mu Han shouted softly and respectfully.

"Well?"

The old man shook his head and opened his sleepy eyes in a daze.

Mu Han hurriedly handed over the jade plaque he had just received from Mu Tiexin: "Senior, my name is Mu Han. I am a second-level disciple of Fengyuan. I am here to select low-grade martial arts techniques."

"Well!"

The old man took the jade token and waved to Mu Han without even looking at it. Then his eyelids drooped and his head moved like a fisherman.

Mu Han bowed and saluted again, then turned and left.

All the collections on the first floor of Zangfeng Pavilion are low-grade martial arts. There are eight rows of wooden shelves in a space of more than ten meters. Jade pieces of various colors are neatly placed on the shelves.

These jade pieces are all low-grade Taoist artifacts.

A piece of jade is a kind of martial arts technique. They are imprinted on the inside of the Taoist tool by the masters of the Mu family. As long as the Taoist tool is activated, the contents will be revealed.

The name of the exercise is written on the surface of each jade piece.

Among them, some techniques are widely spread in Taixuan Tianyu, some are exchanged with other families and sects, and some are original creations of the Mu family.

Starting from the Mu family in the first row, Mu Han scanned at double speed.

Xuanmu Fist, Flame Palm, Qingfeng Eighteen Swords, Tiger Explosion, Rock Skill...

After so many years in the Xuanfeng Academy, Mu Han had heard of all these low-grade martial arts techniques, and had also seen the children of the Mu family practice them. Several of them were very good among the low-grade martial arts techniques. For example,

"Fire Palm", when practiced to the extreme, the true energy is like a raging flame, and a palm slap can almost burn a person to ashes; and the "Rock Skill", if practiced successfully, can also make the body truly like a rock.

However, Mu Han was not interested in any of these techniques.

After reading the low-grade martial arts skills on the wooden shelves in the first row, Mu Han moved to the second row without hesitation, then to the third row, then to the fourth row...

When he reached the middle of the sixth row, Mu Han finally stopped and stared at the palm-sized purple jade piece on the wooden frame with bright eyes:

Lei Jiyin Gang!

"This is it!"

Mu Han smiled broadly and couldn't wait to remove the jade piece imprinted with this technique.

The purpose of his coming to Zangfeng Pavilion was just for it!

This martial arts technique was created by a strong martial artist from the Mu family hundreds of years ago. In terms of power alone, "Lei Ji Yin Gang" is one of the best among all the middle-grade martial arts techniques of the Mu family.

of.

It's just that this technique has very high requirements for practitioners. The speed of absorbing the spiritual energy of heaven and earth and converting it into one's own true energy must be very fast.

At the ninth level of the martial arts realm, the speed at which heaven and earth spiritual energy is converted into true energy can be divided into nine levels. However, to practice "Lei Ji Yin Gang", you need to have the speed of the sixth level. In other words, you must at least have the transformation of a monk in the Hundred Aperture Realm.

The speed of true energy is the basis for practicing "Lei Ji Yin Gang".

However, people with the strength of the Hundred Aperture Realm can basically go to Zangfeng Pavilion to choose a high-grade technique. Who would practice the "Lei Ji Yin Gang" which is only as powerful as a middle-grade martial arts technique?

What's more, the progress of this kind of practice is still very slow.

There were once two masters of the Mu family who were in the Baiqiao realm and spent several years trying this new technique. As a result, they found that the rate of increase in strength during practice was not even as fast as that of their fellow clan members who practiced low-grade martial arts techniques.

As a result, "Lei Ji Yin Gang" has become a tasteless thing.

The grade of this martial arts technique has also been reduced from mid-grade to low-grade. No one is wasting time to practice it anymore. It has been basically ignored for hundreds of years.

Mu Han also learned about the existence of "Lei Ji Yin Gang" a few months ago after listening to some Mu family children chatting.

In recent days, he was considering changing his exercises to cover up the "Purple Jade Smoke Technique". When Mu Han searched for his memory, he immediately chose it. Because of the existence of the "Purple Jade Smoke Technique", Mu Han transformed the aura of heaven and earth into a true form.

The speed of Qi is very fast, so you can definitely try to practice "Lei Ji Yin Gang".

Moreover, Mu Han knew that with his status, it was quite difficult to obtain middle-grade martial arts skills openly, and it was even more impossible to practice them secretly. Whether it was the Mu family or other sects, they secretly learned middle-grade and above without being taught.

Martial arts techniques are all taboo.

If he can successfully cultivate the "Thunder Ji Yin Gang", Mu Han will have the means to compete even if he encounters those disciples in Ruifeng Academy who are specially trained by the Mu family.

Of course, more importantly, this kind of technique that no one practices is very suitable for covering up Mu Han.

"call!"

With a soft breath, Mu Han quickly calmed down his mind, and then with a thought, a tiny trace of magic power overflowed from his heart like a stream, and then penetrated into the jade piece through the thumb and index finger of his right hand.

"boom!"

The Taoist pattern fluctuated, and the low-grade Taoist weapon suddenly emitted brilliant purple light.

Mu Han quickly concentrated his attention and looked at the jade piece without blinking. After a moment, he saw rows of black characters appearing neatly on the surface of the jade piece.

After a few minutes, the purple glow of the jade pieces converged.

Mu Han's eyes were slightly closed, and the "Thunder Ji Yin Gang" skill flashed through his mind. When the jade piece was activated once, the skill would be revealed three times in a row.

After three times, the technique was completely imprinted in Mu Han's heart and was vividly remembered.

After reciting silently several times very fluently from beginning to end, Mu Han put the jade piece back on the wooden stand and turned away. The white-haired old man beside the attic door was still dozing off, and there was even a slight snore coming from his nose.

Mu Han did not disturb him, just bowed slightly, saluted, and left quietly.

After a long time, the white-haired old man yawned, stretched, and woke up.

The old man's cloudy eyes swept across the wooden frame, and the old man's face that looked like dried old tree bark showed a slight surprise: "He is still a little guy with magic power... He actually chose the one that was regarded as worthless.

The 'Lei Ji Yin Gang' of the exercise is interesting, interesting..."

By the end of the story, the old man was smiling and full of interest.

After Mu Han left Zangfeng Pavilion, he did not try to practice immediately. Instead, he stayed quietly in his slightly dilapidated home, trying to figure out the "Leiji Yin Gang" technique one by one.

At this time, the news of the disappearance of Mu Xingkong, Mu Xingfeng, Mu Tianyu, and Mu Tianlan finally attracted the attention of the Mu family, and then caused an uproar in the Mu family...
