Lin Xuan came to the treasure room.

Looking at the Linglong Pagoda in front of him, Lin Xuan did not enter immediately, but his face was full of hesitation.

Speaking of which, the harvest of his trip has greatly exceeded his expectations, although he has not yet obtained the Netherworld Cold Iron, but those ancient treasures and refining materials are also extremely precious.

Could it be that there are even rarer things in the treasure room, Lin Xuan was skeptical about this, maybe it was just a trap set up.

Lin Xuan stroked his forehead with his hand, and after a while, an idea came to mind.

The black light on his body flashed, and the whole person became weird, and then Lin Xuan slapped the spirit beast bag on his waist, and a green-haired monster appeared in front of him.

This is the last walking corpse that Lin Xuan has refined, let him go in to investigate first.

When the zombie received Lin Xuan's order, it immediately turned into a yin wind without hesitation and flew into the Linglong Pagoda, and with the help of the magical power of the Heavenly Devil Corpse Technique, Lin Xuan could also reflect the scenes seen by the walking corpse in his mind one by one.

The pagoda is about seven or eight zhang high, but it is only divided into three floors.

I don't know what material this treasure is made of, it is crystal shining inside, which is very eye-catching, but Lin Xuan controlled the walking corpse to look around on the first floor, but found nothing.

The zombies turned into a yin wind again and flew to the second layer.

Since it's a tower. Naturally, it is small at the top and big at the bottom. The area of the second floor. Only about two-thirds of the ground is on the first floor. And yet on that earth. But it has a layer of cyan ground light. It was filled with ancient treasures and materials. Just like the stone room where Lin Xuan had just gone.

Those ancient treasures are aura-pressing. It looks like it's even more precious. However, Lin Xuan had a thoughtful expression on his face.

Hesitate for a moment. Give commands with your divine sense. The walking corpse stretched out its claws. Grab the shroud hard.

Kiss. It's easy to break the ban. And yet the next moment. The ancient treasures and materials in the shield are gone. In its place was a raging fire.

Bang on the ground. From the claws of zombies to the claws of the earth. Almost in the blink of an eye. and it will be burned into a ball of fire.

Lin Xuan hurriedly took his divine sense back.

Spit out a breath of turbidity, it's dangerous!

This is called the Treasure Room. Sure enough, it was a well-arranged trap, and those ancient treasures and materials were all clever tricks.

He had already expected it in his heart, so there was no surprised expression on Lin Xuan's face.

Lin Xuan was silent for a moment, and then re-released his divine sense to look at the Linglong Pagoda in front of him, since he knew that there were ghosts, of course Lin Xuan would not be deceived, but this pagoda itself was also an ancient treasure, and Lin Xuan naturally wanted to collect it.

Pinch your hands. With a wave of Lin Xuan's hand, a trace of sword qi shot out and submerged into the pagoda. However, there was no movement at all.

Lin Xuan frowned, but he was not discouraged, and continued to perform other treasure-collecting techniques, and in just two pillars of incense, he used all the secret techniques introduced in the Nine Heavens Xuangong and Xuanmo **.

But it still didn't work.

Lin Xuan's face sank, he took out an empty storage bag from his waist, and shook it in the air, and a magic trick hit it.

The storage bag immediately becomes larger and moves out of the mouth of the bag. A colorful glow flew out and rolled towards the Linglong Pagoda.

This time it finally had an effect, the pagoda began to slowly shrink and change, Lin Xuan was overjoyed in his heart, and urged the magic trick with all his might.

A moment later.

Whoosh, the pagoda finally shrunk to a half-foot length and was sucked into the storage bag.

A trace of excitement flashed on Lin Xuan's face, and he hurriedly fastened the mouth of the bag, this ancient treasure was not trivial. However, I haven't mastered the use for the time being, so I can only study it slowly in the future.

Then Lin Xuan didn't stay any longer, walked out of the ancient monk's cave, flipped his palm, and took out a jade tube from the storage bag.

Sinking the divine consciousness into it, the jade cylinder was engraved with a map of the immortal mineral, which Lin Xuan had quietly copied from Mo Mang not long ago.

Although Lin Xuan didn't understand the words of the demon clan on it, fortunately, the picture was very detailed, and Lin Xuan followed the signs on it. Soon found another way.

Unleash your consciousness with all its might. Carefully probing the surrounding scenery, Lin Xuan didn't want all the treasures to be in hand. On the way back, he encountered danger because of carelessness.

Half an hour later.

Lin Xuan looked at the scenery in front of him and was silent.

I took out the treasure map again and compared it, and I was not mistaken, this is the end of the immortal mine.

However, in front of me......

A sea of fire.

Lin Xuan wanted to use his divine sense to investigate, but was immediately bounced back.

There was obviously no road here, of course, Lin Xuan also suspected that this was a trick played by the ancient monks, but when he took a few steps forward, he did feel a terrible heat.

Lin Xuan frowned, he naturally wouldn't be in danger easily, since he couldn't find a way out for a while, there was no need to worry, anyway, cultivators could open the valley, and it wasn't too late to study slowly.

A day passed.

Two days passed.

Three months is a flash......

On this day, Lin Xuan, who was sitting cross-legged on the ground and holding a jade tube in his hand, suddenly raised his head and jumped up.

During this period of time, he has been studying "Xuanji's Experience", of course, the formation is broad and profound, and it takes less than 100 days, not to mention Xiaocheng, it is difficult to even understand, but when Lin Xuan was flipping through this strange book of formations, he happened to see some introductions to the formations in ancient times.

Millions of years ago, that was the golden age of cultivating immortals, and the ancient monks at that time, whether it was exercises, treasures or formation prohibitions, their attainments were far from comparable to what they are now.

And this Xuanji Sanren, in terms of formations, is a genius, not only based on what he has learned in his life, he has made a systematic arrangement of the various formations in the current cultivation realm, but also has a lot of research on the prohibition of formations in ancient times.

These achievements were all written into "Xuanji's Experience" by him.

And in this strange book written by him, there is a kind of prohibition in ancient times, which is quite similar to the sea of fire in front of him.

Lin Xuan was overjoyed, so he naturally devoted himself to studying it, but because his knowledge of the formation was too shallow, it took several months to still swallow the dates, but fortunately, even if he didn't understand the wonder of this formation, the way to crack it was recorded in detail later.

Lin Xuan has already practiced and matured. It's time to give it a try, after all, he can't stay in this abandoned immortal mine forever.

Looking at the sea of fire in front of him, Lin Xuan raised his hand, and five cyan sword qi shot out, and then under the control of his divine sense, they converged into a fist-sized cyan ball.

Lin Xuan's left hand was empty. Let float in the palm of your hand.

Then he ran the Yin and Yang Technique, transformed the Yin Spiritual Power of the Ghost Cultivator, shook his shoulders, and several black qi floated out of his body, which also converged into a black ball of light, which was held on top of his right palm.

Lin Xuandi's face showed a solemn expression, and he carefully raised his hands and moved closer to the middle.

One blue and one black, the two balls of light touched. Then Lin Xuan manipulated the men to begin to fuse, the process was very slow, and it took nearly three sticks of incense. Lin Xuan's forehead was covered with fine drops of sweat, and finally, a ball of light of the same size, but glowing with blue and black, appeared on the palm of his hand.

Lin Xuan also breathed a sigh of relief, if he wanted to break the ban of this ancient monk, he would either reach the realm of a Yuan Infant Cultivator, and with his strong strength, he could naturally do it, or let a cultivator cooperate with a demon cultivator. Of course, the two of them must at least have cultivation above Ning Dan.

Fusion the Spiritual Light Orb!

However, Xuanji Sanren wrote very clearly in the back, this second method is theoretically possible, but it should be impossible in practice, for no other reason, the yin and yang spiritual power is originally mutually exclusive, not to mention that the two spiritual powers must be exactly the same, even if it is a pair of double cultivation partners, it is impossible to have this kind of tacit understanding, not to mention the history of the immortal cultivation world. I haven't heard of any immortal cultivators and demon cultivators forming dual cultivation partners.

Therefore, Xuanji Sanren also teased later, this method is just his whimsical idea.

However, others can't, it doesn't mean that Lin Xuan can't, although the yin and yang spiritual power is mutually exclusive, but there is still the possibility of fusion if it is controlled, the difficulty of this method lies in the tacit understanding of the two people, but Lin Xuan can "Yin and Yang Jue", he can use two kinds of spiritual power at the same time, this tacit understanding is naturally not a problem.

Of course. It's not that it's not at all difficult. Once it is not well controlled, this yin and yang spiritual power will explode. Although the power is not necessarily very great, it is useless to open the shield in the palm of Lin Xuandi's hand!

This is because the orb of light will also be encased in a shield.

Fortunately, Lin Xuan was bold and careful, and his divine sense was strong, far surpassing the monks of the same level, and after some hard work, Xuanji Sanren's idea finally became a reality in his hands.

Lin Xuan glanced at the ball of light glowing in his hand, and with a flick of his robe, he took the sacrifice away, and after a flash of light, he disappeared into the sea of fire.

A muffled sound came into his ears, and the sea of fire shook violently, and the flames were skewered together, but fortunately, Lin Xuan had already prepared and opened the Nine Heavens Spirit Shield as soon as possible.

After a while, however, the fire calmed down again.

Lin Xuan was stunned, could it be that Xuanji Sanren's inference was wrong, this method could not break the ancient prohibition, this was a bit tricky, just thinking of this, the calm sea of fire suddenly throbbed again, and from there came a dense burst of sound like fried beans.

It was still small at first, but then it got bigger and bigger, and the entire cave trembled violently, as if it might collapse at any time, but Lin Xuan was not surprised, and his eyes stared at the front without blinking.

After about a cup of tea, the crackling sound quieted down, and the sea of fire disappeared, and a purple mist appeared in front of me.

A smile appeared at the corner of Lin Xuan's mouth, this familiar scene made him know that what was in front of him was indeed an ancient teleportation array.

Soon, those purple mist entangled, turning into a whirlpool with a diameter of a few feet, Lin Xuan's body flashed with blue light, turning into a frightening rainbow and flying inside.

The sky was spinning for a while, Lin Xuan felt that there was a white mist in front of him, but fortunately, it didn't take much time, and soon, the scene in front of him became clear.

Lin Xuan swept it with his divine sense, and he was not injured, and then turned his head to look at the surrounding scenery.
