The Divine Tree Treasure Mine is indeed a spiritual mountain, and it is the kind of spiritual mountain refined by the gods, which may be a certain sect in the era of the Divine Kingdom, or it may be the foundation of a certain clan.

Inside this spiritual mountain, layers of formations are wrapped.

In this heaven and earth, the formation is roughly Yin and Yang, Sancai, Sixiang, Five Elements, Liuhe, Seven Stars, Bagua, Nine Palaces and Twelve Heavenly Dao Mixed Yuan, a total of nine major formations.

Although the formations in the Divine Tree Treasure Mine did not go beyond the scope of the Nine Great Formations, they were very strange and difficult to judge the fundamentals.

Qin Xuan could only forcibly crack it with the Optimus Ruler, cutting through the gaps in the formation wall layer by layer, barely looking for a way in.

It wasn't until he broke through to the third layer that he finally realized that this great array contained nine great arrays at the same time, which combined with each other was equivalent to creating another heaven and earth, reaching the ultimate realm of the array path - the Great Dao without a trace.

This formation contains infinite variations, and it is difficult to specifically infer which formation it belongs to.

When he broke through to the fourth layer, through several layers of formation walls, he vaguely saw a huge cave hall, as if he had reached the core of the Spirit Mountain, and there was a towering Heavenly Gate inside.

Tianmen is shaped like the archway of the big clan, the quality is like black iron, 100 zhang high, stand on a stone altar, decorate the ancient cangqiu, engrave thousands of tadpole texts, the door is sparkling, as if it is a boiling pool, and constantly spew out a stream of "gas".

There are 10,000 kinds of "qi".

The various "qi" that erupted from this Heavenly Gate were extremely complex, and Qin Xuan could only distinguish a small part of them.

Obviously, this is a teleportation array gate, but it is very different from today's era, or rather, it is very different from other teleportation array gates in this heaven and earth, as for what is the place on the other side of the heavenly gate, I am afraid that you can only know if you walk in.

The last three layers of the array wall absorbed these "qi" for tens of thousands of years, or even longer, and the accumulation of the large array was extremely terrifying, and each layer of the array wall seemed to be no more than a few tens of zhang, but in fact it had solidified like a spirit crystal.

Qin Xuan stretched out the Heavenly Ruler and swiped shallowly across the fifth layer of the formation wall.

At this moment, wisps of purple qi were released from the place where they were crossed, which immediately turned into yin and yang qi, derived the five elements of heaven and earth and all kinds of changes, and the scratches disappeared.

Qin Xuan was secretly surprised.

The last layer of the formation was completely different from the previous four layers, and it was almost to the highest level of the formation path.

To break through this layer, at least the attainments of the Array Dao Grandmaster, and he is only a half-way master, the gap is very far, as for the last two layers, this heaven and earth, I am afraid that no one can break it, and the god realm may not be able to do it.

Although it is impossible to crack the formation of the last three layers, it may not have any gains.

There are seven layers of large arrays outside the Heavenly Gate, and every time they go deeper into one layer, the more mysterious "qi" there are, and in each layer of the array wall, all kinds of spiritual objects are brewing, including the five elements of the spiritual marrow, including the Yuan Magnetic Spiritual Marrow, there are countless of them, and there are even some that Qin Xuan doesn't know at all.

Even the more rare Celestial Aura in the world, there were dozens of wisps in the first four layers of the Great Array.

Since he couldn't continue to break through, Qin Xuan walked in the fourth layer of the formation wall, collecting the five elements of spiritual essence, and occasionally getting a few rays of heavenly aura and an unnamed spiritual object.

This is a five-color stone.

Qin Xuan seemed to have seen it somewhere, and after slowly collecting more than a dozen copies, he finally remembered that this was the kind of special spiritual material that was used to refine the Heaven Replenishing Plate.

Every time the Divine Tree Secret Realm is opened, it will only take fifteen days, which is very short, but after ten years, it will be opened again.

There was not much time left, Qin Xuan didn't care about the first three layers, he used the Optimus Ruler all the way to open the way, slowly walked forward in the fourth layer of the formation wall, surrounded the Heavenly Gate, and walked a few miles, he could collect more than fifty copies of the Yuan Magnetic Spiritual Essence, and there were also more than thirty copies of the other Decanic Water, Yimu, Gengjin, and Lihuo Spiritual Essence.

The number of five-color stones is even less, only six, and the weight is not light, each one seems to be no more than the size of a fist, but it can have a weight of thousands of catties, and the aura of the Celestial Domain is dormant in these five-color stones.

There are about three or four strands in each piece.

This kind of income is by no means small, it is estimated that there are still four hours at most from the period when the secret realm is closed, Qin Xuan returned the original way, and it took a little time to walk out of the Tianmen Great Array.

The center of this large array is the gate of heaven, surrounded by seven layers of array walls, each layer has a hundred zhang thick, the circumference ranges from three or four miles to more than ten miles, there are rare treasures everywhere, and many of them are like returning to the era of the flood that was full of treasures.

Time was pressing, Qin Xuan only searched for three miles in the fourth layer of the formation wall, at best, it was only half of the area of the fourth layer of the formation wall.

Therefore, this is almost an endless treasure of the Heavenly Gate.

Qin Xuan walked out from the depths of the treasure mine, but saw that Yu Susu and Qi Qing Hook were searching the periphery of the Tianmen Great Array, digging stones everywhere, looking for the Yuan Magnetic Spirit Essence.

"Brother, there are a lot of Yuan Magnetic Spiritual Essence in this area, my second sister and I searched for a few days, and we found more than ten copies!" Qi Qinggou couldn't help but be overjoyed, took out the storage bag he was carrying, and opened it for Qin Xuan to see.

"This place is not good for long. Before Qin Xuan finished speaking, the entire treasure mine suddenly shook, "Let's go, go back to the secret realm." ”

The Divine Tree Treasure Mine is not within the scope of the Secret Realm, but it is also sealed underground, if they do not return to the Secret Realm before the Divine Tree Secret Realm is closed, the three of them will likely be sealed in the Treasure Mine and will not be able to get out.

This area is by no means a safe place, in addition to the giant ape clan, there is another more terrifying existence hidden, but in the fifteen days when the secret realm is opened, they will be suppressed somewhere.

At this point, the Divine Tree vaguely remembered, and it also forgot what it was, only saying that it was a special demon race that fed on the Yuan Magnetic Spirit Essence and Spirit Crystal.

Qin Xuan's moonlight flowed like spring water around him, he reached out and grabbed Yu Susu and Qi Qing Hook, and quickly returned to the secret realm, as soon as he stepped into the secret realm with his front foot, he was immediately forcibly ejected by the large array of the entire secret realm, and he didn't even have time to say goodbye to the Nirvana Divine Tree.

"It's okay, in ten years' time, you can come again. The voice of the Nirvana Divine Tree flashed away.

Qin Xuan reluctantly heard this advice, and secretly said in his heart, naturally he wanted to come again, ten years later, if he could get close to the attainments of the Array Dao Grandmaster, he might be able to go one step further and break into the fifth and sixth layers.

Almost at the same time, everyone was ejected by the Great Array of the Secret Realm, and they appeared together outside the cyan wooden door of the labyrinth.

Forty men entered, and now only seventeen come out alive.

"Mu Daoyou!" In the distance, Chen Yu suddenly walked over, and Qin Xuan, who had just stood firmly, arched his hand, and looked at it carefully with a little surprise, "Daoyou's cultivation has improved so quickly, I'm afraid there is an adventure, right?"

While speaking, Teng Yunfeng and the four of them also walked to Qin Xuan's side one after another, forming a half-circle around them.

"Mu Li, I didn't think you still have an evil demon Dao friend?" Teng Yunfeng looked suspicious, he remembered very clearly, more than ten years ago, "Mu Li" was the late stage of forging spirits, and now it is actually the Jindan realm, and it is still the middle stage of Jindan.

At that time, Qin Xuan found a tree hole to refine earth-based spiritual objects, and soon, the entire secret realm ushered in a big storm, and everyone was scattered from then on.

In the past ten days, what good things have happened to "Mu Li" to be able to have such a creation?

Teng Yunfeng couldn't figure it out, and then looked at Teng Qinggou again, and saw that the other party was not hostile, so he bowed his hand slightly, and his expression was inevitably quite disdainful.

"Whether it's Xuan or Demon, they're just cultivators, since they can talk about it, why don't they make friends?" Qin Xuan smiled slightly, secretly estimating in his heart, he always felt that Teng Yunfeng's five people were not good.

"What Daoyou said is reasonable. Teng Yunfeng echoed the sentence and continued, "You and we are also destined, have you ever thought about practicing with us in the future?"

"Oh, what do you say about the rules?" Qin Xuan glanced at the five people, feeling that Chen Xi was not a villain, and the other four were really hard to say.

"There are no rules, since we practice together, we should take what we need. Teng Yunfeng stared at Qin Xuan, still intending to show goodwill, "You should not be from a big clan, and your resources are limited, so there is no disadvantage in joining forces with us." ”

"Not necessarily, not to mention that I already have two Taoist friends by my side. Qin Xuan still smiled gently, and politely thanked the absolute party for his "kindness".

"Okay, I'll just ask you one thing, how many spirit crystals do you want to sell for that space pagoda?" Teng Yunfeng had no intention of recruiting Qin Xuan, he was not stupid, he always felt that this "wooden figurine" had a strange and mysterious origin, and it might not be a good thing to stay in his group.

What he really wanted was Qin Xuan's Sumeru Pagoda.

"Not for sale. ”

"Are you sure?" Teng Yunfeng sneered faintly, and his evil intentions were revealed.

"This Mu Daoyou, more things are better than less, you also know that your pagoda has a great relationship with the five of us, and it is our chance. If you make a price, the five of us are all big sect heirs, and we will definitely not treat you badly. Hua Mu Zhenren, one of the five, also spoke at this time.

This person is a wood-based monk, and the Sumeru Pagoda is also a wood-based space magic weapon, if he can buy it, he will definitely give it to him to cultivate.

Naturally, he wanted to.

"Not for sale!" Qin Xuan replied coldly, arching his hand, "Several, say goodbye!"
