After sitting cross-legged, Lin Quan unhurriedly sank his mind into the sea of consciousness of the Mud Pill Palace.

The spiritual power has been restored, but Lin Quan, who is cautious by nature, still has to carefully observe the specific situation in his sea of consciousness to rest assured. In addition, he was also very curious about what had changed after the magical yin-yang monster fish absorbed a large amount of spiritual power and black and white soul power.

Inside the Mud Pill Palace, there is still a hazy mist space, and there are still one large, two small, and three familiar light clusters. The Taiji diagram that had been clinging to the Great Light Cluster had now been completely separated, and now it was hovering over the Great Light Cluster alone. And the current Taiji diagram is no longer an illusory light cluster, it has completely become a black and white spherical shape formed by an unknown material.

"Huh, what's going on? How did it suddenly become like this?"

Lin Quan panicked. At first, when the two stone fish formed a Taiji Tu light cluster and integrated it into his body, he could barely accept it, after all, that kind of light cluster similar to his own Yuan Shen could be understood as an unknown spiritual power. But he had never heard of a monk who could hold a solid ball in his sea of knowledge.

However, fortunately, he knew that this Taiji-shaped ball was formed by two yin-yang stone fish, which was completely different from some of the evil things recorded in the classics, and looked somewhat similar to Taoist items.

Suppressing the uneasiness in his heart, Lin Quan had no clue after carefully observing it for a long time. Needless to say, if you let a foreign body that is completely unknown to the bottom be in your most important sea of consciousness, it will definitely not work. But he didn't have a better way to find a high-level monk to ask for advice? Not to mention whether he could find a high-level monk with only a fifth-level condensation cultivator, even if he found himself, he would not have a bargaining chip to impress others. The most important thing is that if this magical Tai Chi ball is a treasure, then asking for the help of a high-ranking monk is tantamount to asking for the help of oneself.

Caught in a dilemma, his face couldn't help but become very ugly. After hesitating for a long time, Lin Quan finally made up his mind. He carefully disengaged a spiritual force and gently touched the mysterious Tai Chi ball.

Who knew that when his spiritual power had just come into contact with the Tai Chi ball, Lin Quan suddenly felt that an extremely strong suction force came out of the Tai Chi ball, and this irresistible huge force instantly sucked the entire spiritual power of the unprepared Lin Quan, and he continued to suck in without satisfaction, this change almost scared Lin Quan to the point of dissipation. It wasn't until he finally forcibly cut off his mental power that this huge suction stopped. And when the frightened Lin Quan just wanted to breathe a sigh of relief, his whole person suddenly lost consciousness.

..................

When Lin Quan regained consciousness, he suddenly found himself in a completely unfamiliar space.

It was a strange hemispherical space with a round sky, and the whole space was empty except for a strange nine-sided building in the center. After Lin Quan visually inspected it, he found that the ground in this space was about fifty zhang in radius, and after looking up at the sky, he found that the height was about twenty-five zhang. However, the top and the surrounding area beyond this range were covered by a black and white wall of chaotic light.

He first stamped his feet, and found that the ground, which was all made of unknown yellow-brown soil, was not too hard, and the soil should be similar to ordinary earth. It seems that some simple planting should also be possible here, Lin Quan made a preliminary conclusion.

Then he turned around and walked to the chaotic-colored wall of light around him, and after reaching out and touching it, he found that this wall of light was extremely tough, and there was a faint feeling of horror. Lin Quan only took a cursory glance at it, and he would never come up with any brute force cracking methods. As long as there is a little common sense of cultivating immortals, they will understand that this kind of light wall is an extremely mysterious ancient prohibition. Especially Lin Quan, who had practiced the way of formation, understood that this kind of ancient prohibition containing looming runes was the best in the prohibition. Let's not talk about whether it will have a back-shock and anti-injury to the attacker, even if it is just a simple defensive prohibition, it is enough to make everyone desperate, with Lin Quan's estimate, this ancient prohibition is estimated that a dozen Yuanying monks will not want to break it together.

After circling the entire space, Lin Quan didn't notice any danger for the time being. He sighed and calmed down again. He first silently felt his condition, and then suddenly sat or stood, ran or jumped. After a while, he calmed down again, with a thoughtful expression on his face.

After passing the series of tests just now, Lin Quan was already sure that his current body was not his original physical body, and it seemed that it should be condensed by pure spiritual power. Under this restriction, he is now like an ordinary mortal, unable to meditate and practice, nor can he absorb a trace of spiritual power. In this way, it is naturally impossible to use any martial arts and immortal cultivation realm spells.

"This strange spherical space should be inside the mysterious Taiji Ball, a Taiji Ball that can itself be hidden in the monk's sea of consciousness, and can also bring the monk's spiritual body directly into the Sumeru space through spiritual power...... Well, if it's not a treasure, I'm afraid no one will believe it. But why is it that when you come in, you only need to touch the Tai Chi ball with your spiritual power a little, but now if you want to go out, no matter how much you urge your spiritual power, it has no effect? Well, it seems that the key to figuring out this problem should be there......

After calming down, it only took Lin Quan less than a cup of tea to guess the story of the matter. I saw him muttering a few words to himself, and then set his eyes on the nine-sided building not far away.

The entire structure of this quirky building is made of unknown materials that shimmer with a faint rainbow light, and is about five feet high. Eight of them are engraved with a variety of insects, fish, birds, beasts, flowers and plants, and the last side is two closed quaint gates, with three ancient seals written on the top of the "Yin and Yang Tower"!

"Yin-Yang Tower? It's strange that such a strange thing can be called a tower?"

Lin Quan paced around the nine-sided building several times before standing in front of the door of this 'tower', and after politely calling several times to no avail, Lin Quan laughed at himself and unceremoniously stepped forward and pushed the door.

After a crisp 'squeak', the quaint gate that looked rather heavy was pushed open by Lin Quan. After seeing that the result was indeed as he thought, Lin Quan smiled slightly and walked into the Yin-Yang Tower.

'It's a blessing or a curse, it's a curse that can't be avoided'.

Whether it was to figure out the situation in this strange space or to find a way to leave, this 'Yin-Yang Tower' was the only clue, and Lin Quan had no other chance.

From the outside, the tower is a nine-sided shape, but the space inside the tower is a standard circle. It is the same from the ground to the top, with a radius of about five zhang. The walls around the tower were still made of the same material that emitted a rainbow of light, but the floor had turned a pure swarthy black, and the top was a flawless snow-white color.

After taking in the situation in the entire tower, Lin Quan's heart, which had been slightly relieved, couldn't help but lift it again. It turned out that the entire tower was filled with a faint mist, and there was nothing else.

"Could it be that all my conjectures are wrong, or is the key to leaving this space not in this Yin-Yang Tower at all?"

Lin Quan, who was at a loss, still chose to enter the Yin Yang Tower after thinking about it again and again. He always believed that the core of the entire space was the Yin-Yang Tower, and the reason why he couldn't leave it was because of two reasons. One is that he has not yet discovered the real key, and the other is that this space can only enter and not exit.

"Although the black soil on this ground looks extraordinary, it should have nothing to do with my escape. White ...... on top Forget it, such a high place is also out of reach for me without any spiritual power. Well...... As for the walls here, by the way, could it be that there are some secret rooms or secret doors in this tower that have been specially hidden?"

Undaunted, he rekindled his hope at the thought of this possibility, and walked around the entire wall, stroking every inch he could touch with his hands. When he followed Du Hongbo to learn the Weixuan Formation Method, he also slightly involved some simple knowledge of civil engineering. He still remembers some of the experiences that Du Hongbo told him. That is, in order to prevent the fluctuation of spiritual power from being detected by the enemies of fellow immortal cultivators, some immortal cultivators often use some ordinary tricks that only ordinary mortals can use to hide some important items. Of course, the hidden items themselves must also be items that have been completely isolated from spiritual power, or simply items that have no spiritual power fluctuations.

After more than two hours, Lin Quan, whose eyes were blank, reluctantly gave up. Physically and mentally exhausted, he dragged his heavy steps to the middle. Although his body, which was made up of mental power, did not feel tired, his mind was very tired. Lin Quan, who urgently needed to find a place to rest, naturally subconsciously wanted to find a place with the most dense aura, and the place where the fog was thickest in the entire tower was in the middle.

After a long sigh, Lin Quan sat down without any grace, he was ready to recuperate before making plans. But just as he put his hands back, his expression suddenly moved. Then he rolled over and fell to the ground in ecstasy, excitedly stretching out his palms to caress everywhere, and at the same time using his eyes to carefully observe the ground shrouded in a faint mist.

"Haha, it's really hard to find a place to break through the iron shoes, and it takes no effort to get it!"

After a while, Lin Quan stood up with a wild laugh, and then jumped into the inconspicuous little Taiji diagram in front of him with a slight vertical leap......
