After carefully probing back and forth five times, and making sure that there was absolutely no accident, Xiao Yucai finally used the power of Vientiane and walked to the depths of the earth, taking the power of Vientiane as the guide, and the earth was one, and the distance of three thousand zhang was instantaneous.

"Huh-"

Hundreds of feet away from the destination, Xiao Yu suddenly stopped, the process was originally very smooth, but he had a faint bad feeling in his heart, I don't know if it was because he was too cautious, or if there was really a potential danger.

"What's wrong?" Ziyan asked, she didn't feel anything unusual.

Xiao Yu didn't answer, he properly unfolded his spiritual power, concentrating on perceiving the surrounding environment, and only after a moment did he say in a deep voice, "Ziyan, have you felt that the aura here is different from the one I perceived before. ”

Ziyan's eyes raised slightly, "When do you mean, in my senses, it doesn't seem to be any different." ”

Xiao Yu was slightly surprised, logically speaking, he and Ziyan are connected to perception, what he can perceive, Ziyan can also perceive, is it just an illusion just now......

Xiao Yu concentrated his mind and carefully compared the differences between the two perceptions in the depths of the sea of consciousness, and said after a long time, "The two seem to be related, but they are very different, but I don't know exactly what the difference is." ”

Although Xiao Yu couldn't say that he was sure, he was actually very sure in his words, otherwise he would not insist like this when Zi Yan had already questioned it.

Ziyan thought for a moment and said, "Maybe although you and I have the same mind, we don't have a sense of everything, some very subtle or special things, you can perceive but I can't. ”

Xiao Yu nodded, and there was only this explanation, but although the perception just now had a slight change, it had no substantial impact on him, and the reason why he stopped just now was only because of the pursuit of safety.

After a moment of silence, the divine thoughts in the sea of consciousness moved lightly, Xiao Yu ran the Phaseless Heavenly Book, and the earth energy covered all sides at a steady speed.

He had already probed many times, but he still didn't know the bottom in his heart, so this time he simply made a large-scale probe, centered on himself, and spread parallel to the four directions. The originally dark earth suddenly became like day, and although he could not detect all the areas, all the places he had probed, everything was clearly presented in his sea of consciousness.

Suddenly, Xiao Yu's eyebrows moved, and the power of Vientiane was everywhere, and he actually touched a barrier in the east.

This barrier is too abrupt, because it is not natural at all, not even physical, but it is real, and seals his power from all things.

Xiao Yu was jealous, and he didn't dare to forcibly clash with force, but slowly urged the power of Vientiane to spread in the other three directions, and sure enough, they all touched a barrier one after another.

The distance between these four barriers is very wide, Xiao Yu roughly estimates, it is about nearly 10,000 zhang, this distance is not very terrifying, but because it itself is very abrupt, so Xiao Yu is inevitably jealous.

The existence of the quadruple barrier, for Xiao Yu, confirmed his conjecture to a certain extent, but it did not bring him any joy, because when he was on it, he did not perceive this quadruple enchantment, even the golden bull was not hindered by the barrier, why was there such a quadruple barrier that was almost enchantment set up in the depths of the earth?

In an instant, Xiao Yu had many doubts in his heart, but in a hurry, there was no way to know the answers to these doubts, what the situation was, and he could only find the answers in further exploration.

Xiao Yu weighed for a moment, slowly inhaled a breath, and opened Tianxuan in the depths of the sea, sensing the vision he had touched.

For Xiao Yu, these doubts did affect his determination to a certain extent, but Xiao Yu also knew very well that if he wanted to ask for an opportunity, he would inevitably take a certain risk, and the greater the opportunity, the higher the risk, so he also lost some scruples and opened Tianxuan to perceive everything around him.

Perception was covered, and everything in front of him became clear, but this time he chose not a square plane, but downward.

A hundred zhang away, it was the vision he perceived, and it didn't seem to be anything special, but between the earth and rocks, a dark brown iron wall could be faintly seen.

Xiao Yu was slightly stunned, this iron wall looked very ordinary, but it appeared in the depths of the earth three thousand zhang, and the perception given to him was different from before, so after Xiao Yu was stunned, his spirit couldn't help but be stunned, could it be that the vision he perceived was behind the iron wall?

Xiao Yu walked to the iron wall and stood still, this iron wall is not standing up and down, but lying flat on the ground, Xiao Yu looked forward, the iron wall is not extremely long, it looks like it is only a hundred zhang, but the portal is hidden very deep, and there is no difference at a glance.

It seems that it is not so simple to find the portal, Xiao Yu stretched out his hands, pressed on the iron wall, and ran his mind to perceive carefully, this perception does not matter, and suddenly found that on both sides of the iron wall, there are connected iron walls.

This time it was even more unexpected than Xiao Yu, originally this iron wall had surprised him, but he didn't expect that there were other iron walls connected, and the iron walls on the left and right sides were similar in size to the one he was in. What surprised him even more was that although subconsciously, he called it an iron wall, but he didn't know what material it was made of, let alone who cast it.

Xiao Yu didn't dare to forcibly perceive, only explored along the iron wall one by one, and the more he explored, the more frightened he felt, these iron walls seemed to be endless, every time he finished exploring an iron wall, a new iron wall would appear, these iron walls were not simply lined up in a straight line, but up and down, left and right, there was no end at all.

After Xiao Yu explored nearly three hundred iron walls, he stopped in front of one iron wall, and the doubts in his heart became more and more intense, so far, he had explored so many iron walls, but new iron walls still appeared, and each iron wall was similar, and he couldn't find any portals.

When he was above, Xiao Yu didn't expect that there would be such a large-scale unknown thing below, and he vaguely felt that this might not be the same as what the Taurus was looking for. This conjecture made him both surprised and excited, the secret hidden here was obviously huge, but what it was, he still did not know anything, I am afraid that it would be a great price to get close to the truth.

Xiao Yu took a deep breath, calmed down quietly, and carefully perceived every iron wall, after exploring nearly eight hundred fast iron walls, the scenery in front of him finally changed, showing a boundless forest in front of him, each tree in the forest is dozens of zhang wide, but these tree species are very peculiar, Xiao Yu has never seen it.
