The underground space is full of depression, even if Mu Feng's strength breaks through again, he still feels a huge pressure, compared to Zhang Tian, he is much calmer, and the Quartet Divine Seal exudes a faint light, which seems to offset the faint depression a lot.

"There's a baby down there, haha, it looks like we've earned it. Suddenly, Zhang Tian laughed out loud, and Mu Feng's divine sense did not find any abnormality, which was enough to prove that Zhang Tian's soul realm surpassed him.

"What the hell is it?" Mu Feng wondered, he had already understood Zhang Tian's strength, as the young master of the Heavenly Alliance, his strength was by no means as simple as he imagined, but what treasures existed under the ground of this Origin Demon Star made him even more curious.

And what made him strange was that this time his soul had gone deep into the ground, but the previous soul power did not fight back, if it was impossible for the other party to enter a deep retreat, it was impossible to reach a certain level, as long as he was threatened by an external force, he would definitely fight back independently, but the two of them descended such a long distance without being attacked by any kind.

"If what I expected, this underground is where the core of the Origin Demon Star is located, and it may even be the place where the Ancient Demon Dao originated back then. Zhang Tian said directly.

Hearing him say this, Mu Feng became even more curious, and the two of them accelerated their descent, and here, some immortal stones have appeared around, although they are still relatively mixed, but as long as they are smelted well, they can definitely forge pure immortal stones.

Finally, not long after, Mu Feng also discovered a secret place underground, this is the real underground space, the entire space is surrounded by legendary immortal stones, these immortal stones are treasure-like existence in the cultivation realm, but now they are automatically condensed around the underground space, you can imagine what kind of realm the aura in the secret land has reached.

"It is rumored that the Ancient Demon Dao, the Ancient Immortal Dao, including the Ancient Demon Dao, are several major cultivation factions that have risen after the ancient cultivators, in the most ancient era, this piece of heaven and earth is not divided into the cultivation of the true realm and the immortal realm, and the three thousand planets of the cultivation realm are also full of aura, and then there are a group of great supernatural powers refining the aura of heaven and earth to create the immortal realm, and the aura of each planet in the cultivation realm is gradually weakening, I think that the first demon star was definitely a planet with strong aura, but this became the place where the ancient demon path rose, and the aura of the entire planet was concentrated here, becoming the master of the ancient demon dao。 Zhang Tian said in a deep voice, this is the biggest secret between heaven and earth, even some old antiques of the ancient sect may not know, but the power of the Heavenly Alliance is all over the cultivation realm, and the master of the Heavenly Alliance is even more mysterious, so Zhang Tian will know these things.

And Mu Feng was already stunned, in his cognition, the fairy world should be naturally formed between heaven and earth, after all, such a big world is already beyond the control of human beings, how could he not have thought that the fairy world was actually separated from the cultivation realm by a group of great supernatural powers.

"The reason why there are so many things beyond the scope of the cultivation realm in this universe is because in ancient times, the cultivation realm was thousands of times more prosperous than now, and there were not a few cultivators in that era, but later the heavens and the earth changed, and there were fewer and fewer people who could embark on the path of cultivating the gods, and there were more and more mortals. Zhang Tian explained the reasons one by one.

Mu Feng was stunned, these things are definitely the most confidential things in the world, even Zhang Tian didn't reveal them when he was at his peak in his previous life, I don't know why he said it now.

Zhang Tian seemed to see Mu Feng's thoughts, and only heard him smile slightly: "Big brother, I know that you have had some adventures after being reborn, although I can't see through what exercises you practice, but those who can transcend the laws of the cultivation realm, except for the legendary cultivators, I can't think of anything else, I don't know if my guess is right." ”

Mu Feng was slightly silent, and then nodded directly, "You guessed right, I am indeed a cultivator, and there is no need to hide it from you with the friendship between you and me, but I have set up too many strong enemies in my previous life, and I must not reveal my identity until I reach a certain level, I hope you can understand my hardship." ”

"Hahaha, big brother, don't worry, the cultivator is the strongest existence in heaven and earth, if you can really reach the peak realm, I can't say that my Heavenly Alliance will need your help in the future. Zhang Tian laughed, his eyesight is extraordinary, and the realm is much higher than Mu Feng, he guessed something as early as the first meeting, but Mu Feng didn't say it, he didn't want to break it, now in this underground space, they found the existence of the cultivator, Zhang Tian also happened to take this to show his attitude, Mu Feng no longer needs to hide anything from him, and the cooperation between the Mu family and the Tianmeng will go more smoothly in the future.

At this moment, a cold voice suddenly sounded, "You are not small, you know that the deity is a cultivator, and you dare to break down so swaggeringly." ”

Mu Feng's face changed, the cultivator was the most powerful cultivator in heaven and earth, and this person's soul realm had far surpassed his own, and his strength had definitely surpassed that of the Nine Tribulations Scattered Immortals.

However, Zhang Tian was still indifferent, and suddenly punched out a passage in front of him, and then took the lead in rushing to the depths of the ground, Mu Feng was taken aback, but seeing that Zhang Tian was fearless, he was no longer worried, and followed directly.

The speed of the two of them is extremely fast, but in a breath, they have already traveled thousands of meters, directly into the underground, this is the real underground world, the ore vein above is at best a hole in the ground, compared to here is the difference between a grass house and a palace.

The entire underground world is wrapped in a crystal wall composed of a layer of immortal stones, and the aura is so strong that Mu Feng has only seen it in his life, I am afraid that no one would have thought that there would be such a treasure land in this barren star domain.

When Mu Feng and Zhang Tian entered the underground world, all the pores seemed to be stretched, Mu Feng operated the One Yuan Technique at will, and suddenly a stream of pure immortal yuan power poured into his body, and a little breath was comparable to his usual penance.

"It's really a good place, I'm afraid that only such conditions can provide sufficient cultivation aura for cultivators. Zhang Tian grinned and quipped, and although Mu Feng was absorbing the aura around him, his divine sense was always shrouded in all directions, but he didn't find anything abnormal.

Suddenly, a palace appeared in front of the two of them, it seemed that it had already existed there, and a man in black flew out of the palace, "Stinky boy, you are not small, last time the deity was disdainful of chasing you, but I didn't expect you to dare to send it to the door yourself." ”

Mu Feng snorted coldly, the stinky boy that the other party said was referring to him, as a former Nine Tribulation Scattered Immortal and now a cultivator, plus the bloodline of the Mu family, Mu Feng was originally an unruly person, and those who dared to despise him so much would have died a long time ago, but at this moment, his eyes did not fall on the man in black, but stared closely at the palace behind him.

"Tianxuan Palace!" Mu Feng looked at the palace in surprise, that's right, there are several ancient characters written on the gate of the palace, which are of the same origin as the Shaking Light Immortal Palace, and there is an inexplicable connection with the Tianxuan Immortal Sword in his body.

"It seems that you really have a treasure on you that echoes this Tianxuan Palace. The man in black looked at Mu Feng with disdain, he was originally in retreat and cultivation in the underground space, and he also knew about the mining veins of the First Demon Sect, but he didn't bother to bother with these people at all with his cultivation, but a few days ago, Mu Feng was killing in the mineral veins, and the Tianxuan Sword on his body caused the vibration of the underground Tianxuan Palace, which woke him up, but at that time he had not completely woken up from the retreat, and just launched a soul attack at will, but he didn't expect to be escaped by Mu Feng.

Zhang Tian is obviously also knowledgeable, as the young master of the Heavenly Alliance, he doesn't know how many treasures he has seen, he can see the level of Tianxuan Hall at a glance, a palace of the middle grade immortal weapon level is also a top treasure in the cultivation realm, after all, the strongest of the major super forces is the top grade immortal weapon, in addition, the most precious is the palace of the middle grade immortal weapon.

"Good baby, big brother, it seems that you have another treasure in your hand. Zhang Tian's eyes were still looking around, as if he was looking for other treasures in the underground world.

In the face of this scene, not only Mu Feng, but also the man in black on the opposite side was also ugly, as a cultivator, he had the capital to be proud of the world, originally thought that these two people would be so frightened that they knelt down and begged for mercy when they saw him, even if they didn't do so, at least they should be nervous and vigilant, but no matter how you look at it, Zhang Tian didn't look at him directly, and it is even more impossible to say that he was scared stupid.

Mu Feng smiled bitterly, I really don't know where Zhang Tian got his courage, but seeing that his relaxed appearance was not pretended, Mu Feng was also a lot relieved, as the young master of the Heavenly Alliance, if he died here so simply, the Heavenly Alliance would have been destroyed a long time ago.

"Very good, it seems that you are not afraid of life and death, it just so happens that the deity is still short of two Taoist children, I see that the potential of the two of you is not bad, from now on follow the deity, the deity guarantees that you have a bright future, boy, take out the treasure on your body and let me see, what is it that makes the Tianxuan Hall shake so much." The man in black suddenly laughed, as if the fate of Mu Feng and Zhang Tian was already under his control.

Zhang Tian also nodded, looked at Mu Feng and said, "That's right, big brother, you take out your baby and take a look, I can't bear the child to catch the wolf!"

Looking at Zhang Tian's deceitful smile, Mu Feng suddenly understood, although the man in black had obtained the Tianxuan Palace, he didn't seem to know much about the affairs of the Big Dipper Star Domain, thinking that the treasure on his body was related to the Tianxuan Palace, and he could take it away directly.

Thinking of this, he directly took out the Tianxuan Sword, and then the Tianxuan Hall shook uncontrollably, and the man in black was even more happy, he could see at a glance that the Tianxuan Immortal Sword was at least a top-grade immortal weapon, if he could get it, his strength would definitely go to the next level.

But when he was about to take the Tianxuan Immortal Hall over, Zhang Tian suddenly intervened, one hand on Mu Feng's hand, and suddenly the Tianxuan Hall on the opposite side rose directly from the ground, and finally turned into a small immortal hall in his hand. (To be continued.) )
