Mujia, Foreign Affairs Hall.

There were a few torn robes on the ground, stained with blood, and even stained with a lot of meat scraps, but the logo of the disciples of the Mu Family's Xuanfeng Academy could be faintly distinguished. Not far from these robes were bones and severed limbs, clearly showing signs of gnawing.

In the hall, there were four old men sitting upright, all with gloomy faces. One of the burly old men in black had even reddish eyes, cheeks twitched, and his anger was suppressed to the extreme.

Across from them were two young men, somewhat silent.

In Lieshan City, the strength of the Mu family is so strong, as soon as it was launched, the whereabouts of the four Mu Xingkong were quickly determined, and in the end, in less than half a day, there were two Mu family disciples who traced the traces of the four Mu Xingkong, but unfortunately they had already died, and only brought back these residues.

The four disciples of Xuanfeng Academy died at the same time, which was a great event in the Mu family.

"Bang!"

The black-clothed old man actually smashed the tables next to him with one palm, bounced up, and roared like a lion: "Check! We must find out! Mu Xingfeng, Mu Tianyu, and Mu Tianlan all have Qi Realm cultivation, and my grandson is even a Datong Realm monk, how could they die in the mouths of ordinary beasts? They were definitely killed by someone, and those foreign monks in Lieshan City recently have to find out their identities, and they can't let go of one!"

This old man's name is Mu Feihu, and he is Mu Xingkong's grandfather.

The Mu family has an internal affairs hall and a foreign affairs hall, each with four deacons, and Mu Feihu is the second deacon of the foreign affairs hall, with strong strength and ranking among the eight deacons inside and outside.

Now seeing the tragic death of his grandson, he is so angry that he almost loses his mind.

"Second child, don't be impulsive. ”

Another old man slowly stood up and frowned, "Investigation is a must!" However, they were found in the Black Magic Valley, where there were not only ordinary beasts, but also occasional powerful beasts. Of course, it cannot be ruled out that they were killed and dumped outside the Dark Magic Valley. ”

"If this is the case, our Mu family will never let go of a murderer, and any enemy who dares to provoke our Mu family must be completely wiped out!"

In the end, the old man's mouth was already full of murder.

......

"Lei Ji Yin Gang, it's so wonderful?"

In the bedroom, Mu Han, who was immersed in the skills, finally opened his eyes slightly. Perhaps because of the "Purple Void Divine Palace", Mu Han found that his speed of comprehending martial arts techniques was getting faster and faster. After pondering for most of the day, Mu Han already had a deep understanding of "Lei Ji Yin Gang".

As a result, Mu Han found that this kind of exercise was indeed extremely wonderful, and faintly, Mu Han also felt that this kind of exercise seemed to have some connection with mana.

"Mana ......"

Gently muttering these two words in his mouth, Mu Han's heart suddenly moved, and he quietly ran the "Spirit Law True Technique", and after the mana accumulated in the heart palace overflowed like silk, it followed the exercise line of "Lei Ji Yin Gang" in the body slowly, and it turned out to be unimpeded.

Mu Han is still in the internal cultivation realm of refining the internal organs, without true qi, it stands to reason that it is difficult to urge the operation of the "Lei Ji Yin Gang", even if he has true qi, he has to reach the great passage realm of the twelve righteous meridians and the eight veins of the Qi Sutra, and the speed at which the spiritual energy of heaven and earth is transformed into true qi can keep up with this kind of exercise.

But now, using mana to urge the "Lei Ji Yin Gang" exercise was actually successful.

The predecessor of the Mu family who created the "Lei Ji Yin Gang" was not a Dao Pattern Master, and after the Dao Pattern Master had the strength of the Jade Pivot Realm, he did not need a special exercise to operate the mana, and it was likely that even he did not know that this kind of exercise could also be used by the Dao Pattern Master under the Jade Pivot Realm to mobilize mana.

This discovery greatly encouraged Mu Han.

After the mana ran in his body for a circle, Mu Hanshe went to the "Spirit Law True Technique", a low-grade martial arts technique that specializes in mobilizing mana, and directly operated the "Lei Ji Yin Gang".

In an instant, the mana rushed out of the heart palace at a speed nearly five times faster than before, and it began to run.

"Sure enough, I found a treasure!"

Mu Han was overjoyed, hurriedly jumped out of bed, ran to the courtyard outside in a few steps, and began to run together with the move of "Lei Ji Yin Gang".

There are nine forms of this exercise.

The moves are not complicated, even simpler than the two low-grade martial arts techniques of "Zimu Fist" and "Tiger Explosive Strength", and the treacherous "Spirit Snake Three Changes" cannot be compared, but it is heavy and powerful, wide open and closed, and every time you make a move, there is a kind of momentum that breaks the kettle and sinks the boat, and moves forward.

It only took about ten minutes, and Mu Han was already extremely familiar with the moves.

"Ten times!"

After the "Thunder Pole Sound Gang" was cast again, Mu Han keenly noticed that the speed of mana had increased a little again, and now it was almost ten times that of the "Spirit Law True Technique".

In terms of the mobilization and operation of mana alone, "Lei Ji Yin Gang" can be regarded as a medium-grade exercise, not to mention a medium-grade exercise, even a high-grade exercise.

Adjusting his breathing evenly and calming the excitement in his chest, Mu Han continued to practice, and one move and one style were revealed from Mu Han's hands, which was actually natural, and the connection of the moves was like an antelope hanging on its horns, and there was no trace to be found.

"Boom!"

When the last form was performed, a roar suddenly appeared in Mu Han's body, like rolling thunder.

The moment this thunder sounded, there seemed to be an invisible force violently fluctuating in Mu Han's body, like a wave blowing through Mu Han's internal organs.

It lasted for a few seconds, and the invisible power had dissipated with the sound of thunder.

A slimy feeling emerged, and Mu Han lowered his eyes to find that there was a faint layer of dark black dirt on the surface of his body.

This is...... Visceral impurities?

Mu Han was stunned for a moment, and was immediately surprised.

I didn't expect this "Lei Ji Yin Gang" to also have an effect on the viscera, and the effect is very good. Although it is not as good as the "Purple Jade Smoke Technique", it is definitely stronger than all the low-grade martial arts exercises of the Mu family, and even among the middle-grade martial arts techniques, there are very few that can be stronger than it.

"Looks like even God is helping me!"

Mu Han smiled, and he wanted to continue to cultivate the "Lei Ji Yin Gang", but found that the heart palace was empty. Every time you cast a round of "Thunder Pole Sound Gang", some mana will be consumed, and the thunder sound explosion just now consumes all the remaining mana. However, this is not difficult for Mu Han.

Not long after cultivating with the "Purple Jade Smoke Technique", the mana that could be accumulated in Mu Han's heart palace had reached its peak.

"Boom!"

This time, after the "Thunder Pole Sound Gang" was cast to the ninth form, the thunder sound in Mu Han's body exploded again. This roar consumed most of the mana in the heart palace. Judging from the previous experience, it is no longer possible for the remaining mana to support Lei Yin again, and even if he continues to cultivate, he will only consume mana.

You have to coordinate the "Purple Jade Smoke Recipe" and "Lei Ji Yin Gang"!

Mu Han frowned, his brain spinning rapidly......
