Yi Tian looked at the boulder, and then his right foot shook slightly, and in an instant, a strong eruption came out, directly shattering the grinding disc-sized boulder in front of him, revealing the spiritual spring below it.

The spiritual spring was about a foot long, and it was a small hole, and at this time, from the mouth of the cave, a thick milky white spiritual mist gushed out.

In addition, in the midst of that aura, I saw a liquid like spring water, bubbling out.

However, it looked as if the aura had turned into liquid, but when the liquid flowed out, it suddenly turned into a thick spiritual mist and rose up, making people feel as if they were in a cloud.

"What an amazing aura!" Yi Tian couldn't help but admire.

At this time, he had just inhaled a trace of the aura here, and he suddenly felt that the aura in his body was about to move, and even the feeling of wanting to break through resurfaced.

"Miss Tong, you may have to cultivate here for a period of time, so don't let anyone come in and disturb you. Yi Tian hugged his fist towards childlike love.

"That's nature. Childlike smiled slightly, and then did not stay here for long, turned around and walked in the direction he came.

After instructing the guards at the door, Tong Lian glanced at the mine again, then sighed, turned around and left.

Yi Tian looked at the back of the childlike departure, and he also understood her thoughts, but not to mention that he didn't have that kind of thought now, and even after leaving here, I am afraid he will never come back.

Immediately, after sighing secretly, Yi Tian also looked at the spiritual spring.

"There's something quirky about this place. But at this moment, Moro suddenly spoke.

"Huh?" Yi Tian's expression moved when he heard this, and then his divine thoughts were released, and he quickly glanced around, but he didn't find anything strange, and couldn't help but wonder, "What is strange?"

"The spiritual veins here are just low-grade, and it is almost impossible to give birth to a spiritual spring, and I don't think this spiritual spring looks like an ordinary spiritual spring, but like a ......" Mo Luo was also a little puzzled in his tone.

"Put your mind together and try to probe underground. Moro then said.

When Yi Tian heard this, his huge divine power surged out in an instant, and then instead of spreading out in all directions, it gathered in one place, like a straight line towards the bottom of the spiritual spring.

In the underground, the scope of the Divine Thought's exploration has been greatly affected, even with Yi Tian's current Divine Thought's strength, it is only Kankan that has only extended to four hundred zhang, and then it will no longer be able to advance an inch.

Seeing this, Mo Luo did not hesitate, and quickly released the power of his divine thoughts, fusing them with the power of Yi Tian's divine thoughts, and then continued to extend downward.

Speaking of which, this kind of method of divine thought fusion is still only possible by Mo Luo, and it is extremely difficult for the power of these different divine thoughts to fuse with each other, but I don't know if it is because Mo Luo once took away Yi Tian, or because the power of Mo Luo's divine thoughts is strong enough, so it also leads to the fact that the power of the two divine thoughts can be easily fused.

Finally, under the exploration of the power of this fused divine thought, after continuing to explore the distance of about 600 zhang, about 1,000 zhang from the ground, there was a layer of invisible resistance, preventing Yi Tian's divine thought from continuing to explore.

"This is ......" Yi Tian was also shocked at the moment, but he didn't expect it to be really strange underground.

"It seems that this layer of protection is not strong, if it is forced to break in, it should be possible. "I can vaguely feel that there should be something unusual in this, and if you can get in, I'm afraid it will also be a creation for you." ”

Seeing this, Yi Tian's eyes flashed, and the light of the Qiankun Ring in his hand flashed, and an earthy yellow talisman floated out, which was rolled by Yi Tian with spiritual power and levitated in front of him.

"Although I also prepared some retreat talismans when I came, a low-level retreat talisman like this can go deep into the ground for up to 300 zhang, and the duration is extremely short, not enough to support a depth of 1,000 zhang at all. Yi Tian shook his head slightly.

"It's a bit of a hassle...... "Mo Luo also fell into thought when he heard this.

"By the way, don't you still have some of the remaining array equipment on you from when you set up the 'Shagang Extermination Array'?" At this time, Mo Luo suddenly asked as if he remembered something.

"Well, there are still a few more. Although he didn't know what Mo Luo was going to do, Yi Tian still responded.

"I can set up a temporary small retreat formation, although it won't last long, it should be enough to hold out until the layer of protection is broken. Moro said with some excitement.

Yi Tian also had a flash of joy in his eyes, and immediately the light of the Qiankun Ring in his hand flashed, and in an instant, more than a dozen array instruments of different forms were suspended on his side, and then he saw the power of Mo Luo's divine thoughts surging out, controlling those array tools to arrange each other, and letting Yi Tian inject spiritual power into them from time to time.

After about half an hour, a small triangular formation suddenly appeared, like a triangular light mask, enveloping Yi Tian's body, and the whole exuded a faint earthy yellow light.

"Formation ......" Yi Tian looked at this faint light shield, and couldn't help but be fascinated by this formation.

"Hehe, don't worry about it, this seat has only achieved a little success after carefully studying this formation for hundreds of years. As for your ......" Mo Luo couldn't help but smile smugly when he heard Yi Tianwu muttering to himself, "Let's wait until you cultivate for a while." ”

Yi Tian was also a little helpless when he heard this, but he also understood the truth that greed can't chew too much, there are many cultivation systems in this world, some people refine the formation, and some people refine the power of divine thoughts, but as long as they cultivate any one to the point of profundity, they can become the super strong person standing at the top of the pyramid.

Immediately, Yi Tian used his spiritual power, and saw that on the triangular light shield that was shrouded outside his body, a burst of earthy yellow light suddenly burst out, and then slowly immersed into the ground.

The speed of the retreat formation was very slow, and in the process of descending, Yi Tian could see some gray-white stones along the way, and the ones wrapped in them were spirit stones.

Half an hour passed, and it slowly descended about three hundred zhang, which made Yi Tian feel helpless.

However, there was no way to do this, and after waiting patiently for an hour or so, Yi Tian finally slowly descended to the place that Mo Luo said.

There was no difference between this place and the ordinary underground, densely covered with gravel and soil that had become extremely hard, but Yi Tian could feel that the aura in this place seemed to have become extremely thick, even beyond the ground.

When Yi Tian wanted to continue sinking, he seemed to be blocked by an invisible obstacle, and he could no longer move in the slightest.

"Use all your strength to break this barrier!" Moro said in a deep voice.

Yi Tian's eyes flashed, his body was filled with yellow aura, and he stepped out of the formation in one step, and then his legs were like whip shadows, fiercely pumping towards the invisible obstacle, and each of his blows was powerful and heavy, as if it could shake the mountains!

Under Yi Tian's repeated blows, the dense gravel and soil in front of him trembled and dispersed to the side, revealing a layer of crystal walls completely made of milky white crystals, and even Yi Tian could feel an amazing aura from above!

In an instant, Yi Tian used the spiritual power in his body, and his entire right leg seemed to be dyed with a faint layer of gold, and then a burst of Xuanhuang Qi permeated, tearing the surrounding soil, and slamming heavily into the crystal wall.

The crystal wall only lasted for a moment, and then it suddenly shattered in a click, and then broke a gap more than one person high, Yi Tian saw that he didn't hesitate at all, and his figure flashed into it.

"Wow!"

Suddenly, Yi Tian only felt the emptiness under his feet, and then his figure involuntarily fell down.

In an instant, the thunder light wings appeared behind Yi Tian, and with a flap of his wings, he immediately stabilized his figure, and then Yi Tian looked around.

This is a small enclosed space, about dozens of zhang square, the light is slightly dim, and the most obvious thing is a pool below, which exudes an amazing aura, extremely pure.

However, to Yi Tian's horror, in the middle of the pool, there was a pitch-black humanoid creature!

The pitch-black humanoid remained motionless, as if dead, and was bound by four white chains that stretched out around the pool.

And when Yi Tian's gaze swept to another place, his face changed again, and he saw that not far from the pitch-black humanoid creature was still sitting on a skeleton, and a Dao robe was still draped on his body.

"This ......"

Yi Tian was shocked by the scene in front of him, he didn't expect that there was such a mysterious place hidden under this thousand-foot underground, if it wasn't for Mo Luo to find out, I'm afraid that even if this place would be hundreds of years later, no one would find it.

"If I'm right, this should be a sealed place. Moro said solemnly.

"The Sealed Land?" Yi Tian slowly fell to the ground and walked not far from the skeleton.

"Well, when the war broke out between the demons and the human race, the war spread all over the country, and even this popular continent was involved, because even after the demon powerhouse died, the demonic energy emitted from his body would gradually erode people's minds, and even contrary to the aura of heaven and earth, it would gradually erode the aura. ”

"So in order to avoid this situation, the human race will often seal it after killing the demon powerhouse, so that its demonic energy will not spread, so that the sealed place is formed, and most of the demon ruins you are talking about are formed in this way. Moro explained.

"I see. Yi Tian was a little stunned.

"But it seems that these two people should have died together, otherwise, this human skeleton would not have appeared here......" Moro said after thinking for a moment.
