If Ye Xiaotian's soul was a little weaker, or that kind of soul attack was a little stronger, then Ye Xiaotian's soul at this time would definitely be injured!

Ye Xiaotian couldn't help but be shocked by this, his immortal sense had been completely withdrawn, but his soul was still on the verge of being traumatized.

At the same time, he also feels fortunate that he has successfully stepped into the core planet and is about to learn the secrets of the forbidden land!

Ye Xiaotian's body was filled with a rich blue energy, and this energy was slowly pressing into Xuantian's body, Ye Xiaotian naturally discovered this, and couldn't help but be a little worried, could his True Yuan refine these energies?

Because Ye Xiaotian couldn't use the Immortal Sense to discern the surname of the blue energy around his body, and he couldn't refuse this energy pouring into his body, he could only sink the Immortal Sense into his body to observe.

After a while, Ye Xiaotian finally breathed a sigh of relief, this kind of energy was very similar to the surname of the true yuan in his body, so there was no conflict between them, the two quickly merged into one, and finally all of them were transformed into his own true yuan.

Since this energy had no effect on him, Ye Xiaotian ignored it and began to look at the environment around him.

Although he had just taken a look at it in the sky above, he was focusing all his energy on the strange soul attack, and as soon as he found something wrong, he was ready to move away immediately. So all he knew was that the planet was blue in its entirety, and that he didn't know anything else.

Ye Xiaotian found that the ground under his feet was all a dark blue stone, which was bright and clear, like a spar, and the entire ground seemed to be connected. Looking into the distance, there is nothing but the blue energy and the blue ground, of course, there are many mountains on this planet, but these mountains are also made of this blue stone, and there are no plants to survive.

This made him wonder, could it be that there were only a few cores of the forbidden land, and there were no secrets?

However, Ye Xiaotian immediately ruled out this possibility, after all, this is the core planet of the forbidden land, even if it does not have any secrets, there should always be something special, and the scene in front of him has nothing worth noting at all.

Suddenly, a top-grade immortal sword appeared in Ye Xiaotian's hand, only to see that the immortal sword suddenly broke out of his control and stabbed rapidly on the ground in front of him.

There was a crisp sound of "click......, and half of the body of the superb fairy sword pierced into the ground, and a small crack appeared on the ground that it attacked.

"Huh?" Ye Xiaotian couldn't help but be surprised.

With the full force of the best immortal sword, it was not difficult to destroy a planet, but the attack he had just made only caused a slight crack.

Although Ye Xiaotian didn't attack with all his strength just now, even if it was a casual blow by himself, it was very easy to cause a big crater with a radius of a hundred miles.

Ye Xiaotian immediately took back the top-grade immortal sword, crossed Zhenyuan into the immortal sword, and stabbed fiercely at the ground under his feet!

This time, he's done with all his might!

"......Boom" Ye Xiaotian only felt the ground shake, and a crack appeared on the ground under his feet that was one foot wide and hundreds of meters.

"This ......" he couldn't believe it, with his full strength attack, he only made such a small crack, what is this planet made of?

Ye Xiaotian withdrew the immortal sword again, and then kept attacking the ground under his feet...... A moment later, there was blue gravel of various sizes everywhere within a kilometer of him.

Since he couldn't use immortal sense, Ye Xiaotian couldn't tell if it could be used for refining weapons. The reason why he spent a lot of effort to get these broken stones was because he liked how hard it was, and if he could use it to refine the flying sword, the effect would be good, at least much stronger than the blue stones he had collected before.

In fact, these two kinds of stones are blue, and there is no difference just by looking at their appearance, and the reason why Ye Xiaotian thinks that the difference between the two is entirely based on their hardness, because he has already tried it, and the former is far less hard than the latter.

Immediately, Ye Xiaotian received all the broken stones into a separate storage ring, as for whether these stones could be used for refining weapons, he was going to wait and study later. The most important thing right now is to find out what secrets are hidden here.

Ye Xiaotian's body gradually floated up, and then flew forward...... Immortal Sense can't be used, he can only fly slowly and explore the entire planet.

However, the flying speed of cultivators is quite fast, especially Ye Xiaotian, his speed is terrifying!

In just three hours, he flew around the massive planet, but he didn't find anything special.

The whole planet is made entirely of that blue stone, and there are no other hues at all. The blue planet surface, the blue energy, everything is blue...... "How can this be?" Ye Xiaotian muttered to himself.

Although he had looked at the entire planet himself, he still didn't believe it. Will the Forbidden Core be so simple?

And the energy that attacks the soul is transmitted from this planet, but he has not discovered where the power of this attack comes from. So, there must be a secret on this planet, but I haven't discovered it.

Ye Xiaotian was not discouraged, and continued to fly over the planet...... After three days of flying, he finally discovered a special place.

Within a ten-mile radius of the planet's central prescription, the blue energy here was slightly thinner than the rest of the world, and this was the only thing he had discovered.

Ye Xiaotian was constantly flying or walking around within a radius of ten miles, trying to find some anomalies.

"Huh?" Ye Xiaotian suddenly sighed softly, because at this moment, a golden circle composed of energy and about three meters in diameter appeared in front of him.

He couldn't help but wonder how he hadn't noticed this golden circle of energy all along, "Could it be that the visual angle is different?" he guessed.

Immediately, Ye Xiaotian walked towards the golden energy circle in front of him.

When he walked in front of the golden energy circle, he suddenly felt a huge suction pulling on him, he wanted to counter, but that suction was quite terrifying, with Ye Xiaotian's cultivation at this time, he was sucked in before he could react!

The moment he was sucked into the golden circle of light by the terrifying pulling force, Ye Xiaotian hurriedly sacrificed the Nine Rank Lotus Terrace, and used the True Yuan to arrange a defensive shield around him. At the same time, the Chaos Spirit Devouring Sword was also tightly held in his hand.

Ye Xiaotian didn't know where he would be sucked in, so he had to plan for the worst, and he showed all his hole cards.
