A phantom shadow was condensed in his mind, accompanying Xiao Suying and the others in the space of the Heart Palace, while Mu Han's body had already left the lakeside with Qinghuo and galloped forward.

"Qinghuo, is this really the 'Great Cave Immortal Ruins'?"

It didn't take long for Mu Han's figure to stop at the top of a hill, his face full of doubt. Just now, he used his mind to roughly probe and found that this space was actually only hundreds of miles in radius, which was completely inconsistent with the information that Mu Han had learned.

Gu Cangfeng once revealed that the "Great Cave Immortal Ruins" are extremely vast, at least tens of thousands of miles in radius.

"Probably right......

Qinghuo said with a slight hesitation, he had already noticed that this area was quite narrow, and it didn't look like the space of the Martial Immortal Realm Heart Palace at all.

But after only a moment, the hesitation on Qinghuo's face had disappeared, and he said categorically, "This is definitely the 'Great Cave Immortal Ruins'! otherwise, the power against your soul in the passage of the Southern Immortal Gate would not be so powerful, and it would be difficult for even me in the Triple Void Tribulation to enter. 」

"In that case, why is this space so cramped?"

"This ......"

Regarding Mu Han's question, Qinghuo didn't know how to explain it. On the contrary, it was Mu Han, who muttered softly to himself after pondering for a long time: "Could it be that this 'Great Cave Immortal Ruin' is the same as the 'Senluo Realm' of the Taixuan Heaven Domain, and there is also an area similar to the 'Realm within the Realm'?"

"A realm within a boundary?"

Qinghuo was stunned, and then his eyes lit up, "Yes! Yes! It must be so! The entrance of the South Immortal Gate leads to the 'Realm within the Boundary' of the 'Great Cave Immortal Ruins'. Only in this way can we explain why, for so many years, the monks of the 'Kunlun Immortal Mansion' have never discovered the 'Biluo Immortal Spring'. 」

Mu Han nodded, and Qinghuo's last sentence made him quite agree.

This "Great Cave Immortal Ruins" is only open to every Holy Son of the Kunlun Immortal Mansion for one month, but for the super powerhouses of the Void Tribulation Realm such as the Mansion Master, there is no such restriction. Nowadays, the "Kunlun Immortal Mansion" is quite familiar with the situation inside the "Dadong Immortal Ruins". Such an obvious "Biluo Immortal Spring" was not found, which is obviously unreasonable.

But if Biluo Immortal Spring is hidden in the "Realm within the Realm" of the "Great Cave Immortal Ruins", which has not yet been found by the "Kunlun Immortal Mansion", then it makes sense.

"I don't know that there is nothing but 'Biluo Immortal Spring' here. Are there any other treasures?"

Mu Han had just turned such a thought in his mind, and an earth-shattering roar suddenly drilled into his ears: "Who! Who moved the old man's immortal spring?"

"Anyone?"

Hearing this voice, Mu Han and Qinghuo were both taken aback, there was actually someone in this place. And depending on the situation, it seems that he is still the owner of the "Biluo Immortal Spring"?

After exchanging glances with Qinghuo, Mu Han immediately ran the "Taixu Cave Divine Technique" to the extreme. Gather your own breath, but your mind quietly covers the place where you came.

After a while, the picture around the lake unfolded in Mu Han's mind.

At the edge of the dry lake, the crack that was previously split by Mu Han's knife had been closed, but other than that, there was nothing unusual around the lake, and there was no half-human figure. Mu Han was puzzled. Since there was no one, where did that roar come from?

At this moment, Qinghuo's exclamation suddenly sounded directly in Mu Han's soul: "Mu Han, look, that lake center!"

"Huh?"

Mu Han was slightly stunned. His attention immediately shifted to the center of the lake, and in an instant, Mu Han "saw" a small and delicate white figure in the place where the "Biluo Immortal Stone" had been placed, with white hair and hair, and it was obviously not young, but its body was only the size of a thumb.

At this time, the old man was like a little white elf, jumping up and down at the bottom of the uneven lake, and his little face was full of anger.

The moment this scene appeared in his mind, Mu Han's eyes almost popped out, and on the elf's body, Mu Han couldn't sense any breath, as if the body was composed of the air in this area, and there was no sense of existence.

Because of this, Mu Han didn't find him at the beginning.

"What's that?"

Mu Han's thoughts were transmitted to the depths of Qinghuo's soul, and with the "Purple Flame Totem", the two could easily communicate in this secret way.

"Demon Spirit Clan!" Qinghuo narrowed his eyes and spat out these three words violently.

"Demon Clan?"

Mu Han suddenly remembered the nine alien races that Qinghuo had talked about, and his face couldn't help but show surprise, "How could the Demon Spirit Clan appear here?"

Qinghuo shook his head: "It's hard to say, it's possible that like us, they all came in from the South Immortal Gate, or they were caught by the 'Big Cave Immortal' back then, and the 'Big Cave Immortal' died, and the heart palace space turned into the 'Big Cave Immortal Ruins', and he stayed here." 」

After a slight pause, Qinghuo frowned again and said, "For the Demon Spirit Clan, the smaller the body, the stronger the strength, and judging by the size of this body, it should be roughly the same as the previous me. 」

"Triple Void Tribulation......

Mu Han was a little worried, but Qinghuo suddenly shouted, "It's not good, it's been discovered!"

Almost at the moment when this voice sounded, the Demon Spirit Clansmen who were bouncing in the depths of the lake had already jumped into the air and galloped towards this direction, and their mouths shouted angrily: "Don't run! Return the 'Biluo Immortal Spring'!" This sound was like thunder, rolling and stirring, if he hadn't heard it with his own ears, Mu Han really couldn't believe that such an earth-shaking sound actually erupted from a small body.

"Whoosh!"

Mu Han was shocked but not panicked, and in his thoughts, Qinghuo entered the heart palace space again, and Mu Han was suddenly the only one left in this place. However, Mu Han did not choose to escape, but at the same time as running the "Taixu Cave Divine Technique" to the extreme, he also used the "Sumeru Method".

The next moment, Mu Han's body had melted into the void and disappeared without a trace.

If it is the shadow man of the Triple Void Tribulation, Mu Han can still use the power of the "Xuanhuang Sun Gangqi" to contend with it, but he is facing the Demon Spirit Clan of the Triple Void Tribulation, and the "Xuanhuang Sun Gangqi" will not play a role at all, even if Mu Han tries his best, he will not be his opponent.

If Qinghuo recovers to the Triple Void Tribulation, you can still try.

"Whoosh!"

In a few breaths, a sharp voice burst out in the void, and the small figure of the old man of the Demon Spirit Clan suddenly flashed in the place where Mu Han disappeared.

"Hmm, where did you flee?"

The old man in white looked around, and suddenly burst out with an earth-shattering roar from his mouth, "Come out! to the old man...... Go out...... Come on, ......" The moment each note rushed out of the throat of this old man of the Demon Spirit Clan, it was like a thousand explosions of thunder exploding at the same time, and the terrifying sound waves spread out like a tidal wave.

What is especially amazing is that this sound wave is as strong as a burst, and the first wave has not disappeared, and the next wave has followed, and when the last word "come" sounds, this void has been distorted to the extreme, and the powerful force continues to spread around, shattering countless sand and stones on the ground.

...... (To be continued.) )
