"If I'm not mistaken, it should be a signature technique of the Demon Spirit Clan, 'Battle Cry Demon Sound', attacking the enemy with sound, it is very powerful, and can even shatter the soul of a weaker opponent. Hearing Mu Han say the movement of the outside world, Qinghuo couldn't help but be surprised.

"It's dangerous!"

Mu Han was secretly happy.

Fortunately, when he hid his body, for the sake of safety, he integrated that trace of immortal power into the small space condensed by the "Sumeru Upper Method", which greatly increased his resistance. Otherwise, under such a fierce attack by the old man of the Demon Spirit Clan, the small space where he was hiding might have collapsed.

But even so, the small space where he hid was pushed out hundreds of miles by the sound waves roared by the old man of the Demon Spirit Clan.

At this moment, Mu Han's position was already extremely close to the orange space barrier.

"Huh, what's that?"

Mu Han exhaled in surprise, in a valley about 100 meters away from the space barrier, there was an extremely majestic temple, about hundreds of meters in length, width and height, the most surprising thing for Mu Han was that the entire temple was built of stone, and it was still a stone.

The building seems to have been carved out of a single boulder.

Although he was surprised by that hall in his heart, Mu Han did not act rashly, with the strength of the old man of the Demon Spirit Clan, as long as he made a slight move, he might be exposed to his whereabouts. Once detected by the other party, the method of "Sumeru Shangfa" will completely lose its effect.

It's just like when I first met Qinghuo.

"Come out for the old man...... Give the old man a ......."

The angry roars of the old man of the Demon Spirit Clan rang out one after another.

The terrifying sound wave spread and expanded in all directions, and this area with a radius of only a few hundred miles kept vibrating, and the void around the old man's body seemed to be unable to withstand such a violent sound wave impact anymore, and it actually emitted a deafening explosion one after another.

Suddenly, Mu Han noticed that something was not quite right: "No, why is the voice approaching this way?"

"Could it be...... Exposed?"

Mu Han's heart couldn't help but chuckle, and he reflexively wanted to move to the side. But in the next moment, Mu Han had calmed down and quietly hid in the void. But his attention was all focused on the direction where the old man of the Demon Spirit Clan was, closely observing the movement over there.

After a few moments, the roar of the demon spirit people had stopped, and it didn't take long. The powerful sound wave disappeared without a trace.

"Whoosh!" a small white dot flew in from a distance.

"He's coming!"

Mu Han didn't move, but he was quite nervous in his heart.

The powerhouse of the Demon Spirit Clan was as fast as a meteor, and the distance between him and Mu Han shrank rapidly. After a while, a scene that made Mu Han feel relieved appeared, and the small figure actually roared through the void about five hundred meters away from Mu Han, and its target was the gate of the huge stone hall.

"Not found!"

Mu Han sighed secretly, however, the big stone in his heart had just landed. The heart seemed to jump out of his throat again, and the old man of the Demon Spirit Clan actually stopped in front of the temple gate, and looked at Mu Han with a pair of eyes, and the angry gaze seemed to have condensed into substance.

"Hey, he doesn't seem to be targeting himself......

Mu Han suddenly found that the old man of the Shadow Clan didn't seem to be looking at him. But as soon as such a thought came to his mind, a loud explosion came from obliquely behind.

"Boom!"

The blazing red light flashed, and a narrow spatial crack suddenly revealed at the orange spatial barrier behind it, expanding rapidly.

By the time the red glow had faded, the crack was several meters wide.

"Whoosh!whoosh!whoosh!"

The subtle sound of breaking the air sounded one after another, and three figures suddenly rushed out of the crack, through which they could vaguely see the vast and barren space opposite.

"It's done! It's finally done!"

"Sure enough, there really is a hidden space in the 'Great Cave Immortal Ruins'!"

"I don't know what treasures there are in this space?after finding it, this 'Big Cave Immortal Ruins' can almost be abandoned!haha......

「......」

Excited voices rang out one after another.

Mu Han subconsciously shifted his attention, and the three old men who walked in through the crack were three old men, one had a slender body, crane hair and a childish face, and a fairy wind and bones, one was wearing a red robe, extremely burly, holding a fiery red giant knife in his hand, and the last person was a young man in black with a handsome face.

"Fu Xianming?"

The name popped out of Mu Han's mind.

The moment he saw those three faces, Mu Han immediately recognized the identity of one of them, when he first entered the "Kunlun Immortal Mansion", Fu Xianming revealed a huge and incomparable head phantom, which gave him a great shock. Even now, Mu Han still remembers the scene vividly.

As for the red-robed old man and the black-robed man, although Mu Han didn't know each other, the aura that could emanate from their bodies was extremely terrifying. Among them, the aura of the red-robed old man was only stronger than the old man of the Demon Spirit Clan of the Triple Void Tribulation, and it was likely to be the strong man of the Quadruple Void Tribulation.

The young man in black was a little weaker, thinking that it was a double catastrophe.

"Those two people, like Fu Xianming, are also 'Kunlun Immortal Mansion' monks?"

This thought quickly flashed through his heart, Mu Han couldn't help but fall into deep thought, Fu Xianming and the others appeared here, indicating that the fierce battle between the Shadow Clan and the Martial Dao Monk in the Taisu Ancient City had ended, and I don't know which side won the final victory in the end, and what was the situation of the mountain lord?

In addition, the information they just revealed was quite rich.

This "Great Cave Immortal Ruins" has been looted by the "Kunlun Immortal Mansion" for many years, and the good things should have been found. Fu Xianming and the others should have known about this hidden space in the "Great Cave Immortal Ruins", but they only broke it until now and forcibly broke in.

The treasures of this hidden space are also scavenged, and the "Great Cave Immortal Ruins" will be completely abandoned.

Thinking of this, Mu Han was suddenly shocked, when Fu Xianming agreed to Gu Cangfeng's request, maybe he was delaying time and paralyzing the other party, once he entered this hidden space, there was no need for the "Kunlun Immortal Mansion" to rely on the power of the five major sects to attract the power of the heavenly veins to strengthen the "Great Cave Immortal Ruins".

At that time, the "Kunlun Immortal Mansion" may completely turn against the five major sects.

Fortunately, Fu Xianming and the others entered this small space one step earlier, otherwise, I am afraid that even the "Biluo Immortal Spring" will be taken away by them.

"Who are you?"

At the moment when Mu Han's mind was in a hurry, the loud shouts suddenly stirred the heavens and the earth, and the old man of the Demon Spirit Clan's eyes widened, his face was full of anger, and with the sound wave inspired by the "Battle Roar Demon Sound" technique, he frantically swept away towards Fu Xianming and the three of them on the opposite side, and everywhere he passed, the dust was flying, and the sand and stones were all in pieces, and the momentum was incomparably terrifying, as if it could crush any obstacle in front of him into powder.
