At the end of the stone path, Nie Tian and Yanlong Armor had a clear division of labor, one was absorbing the aura of heaven and earth, and the other was gathering the energy of flames.

Nie Tian's spiritual sea was violent and disorderly, and in the misty spiritual sea, all spiritual power was swirling in the form of mist, uncontrollable.

He tried his best to bring those auras and restore them to peace.

But he found that the more he tried to control it, the more violent those spiritual qi became, like a furious beast that could not be suppressed.

"Qi Refining Realm, Acquired Realm ......"

He gradually calmed down, ignoring the mania of Linghai for a while, but thinking about his master Wu Lone's explanation of the Qi Refining Realm and the Acquired Realm.

According to Wu Lone, he knew that once the Qi Refiner crossed the Qi Refining Realm and stepped into the Acquired Realm, the Spirit Sea would ...... It seems that there will be a huge change.

Wu Lin didn't say exactly what that change was, but told him that once he broke through, he would naturally understand immediately.

Wu Lin told him that starting from the acquired realm, every realm leap, flesh and blood, spiritual sea, and soul, may produce different wonderful changes.

The process of mutation requires him to understand it with his own heart, and only by pondering it himself, without relying on the descriptions of others, can he most clearly understand the difference between one realm and another.

"Change ......"

He muttered secretly, calming down, to carefully capture the movement of his soul.

When he didn't think about the bottleneck and only focused on the changes in the spiritual sea, he suddenly found ...... The mania of the spiritual sea, the restlessness of those misty aura, did not seem to be traceless.

He saw that those spiritual auras flowing everywhere seemed to want to condense together, as if they were about to form something.

He no longer tried to calm down the turbulent mist aura, but instead concentrated his mental consciousness, trying to speed up the turbulence of those auras according to the abnormal movements of those aura.

He let go of himself and took the initiative to cooperate with Linghai's approach, which was like adding a handful of firewood to the oil pot, making Linghai's riot even more turbulent and intense.

The mist-like aura of the riot, in his spiritual sea, churned, gathered, and gathered wildly!

Not long after, a large amount of spiritual energy gathered more and more, and in his spiritual sea, an unstable spiritual energy vortex was formed.

As soon as the aura vortex was formed, the surrounding disorderly, scattered everywhere, and turbulent aura everywhere seemed to have found an outlet all of a sudden.

"Whew!"

Wisps of spiritual power mist converged from all directions, and all of them poured into the spiritual power vortex.

The vortex of spiritual power that had just formed, which was still unstable, swirled faster and more violently after those misty spiritual powers frantically gathered!

A suction force suddenly sprouted from the center of the spiritual power vortex!

At this moment, Nie Tian suddenly felt that his spiritual sea, the speed at which he absorbed the spiritual energy of heaven and earth, instantly increased several times!

Originally, he needed to use the Qi Refining Technique to constantly guide in order to merge the Heaven and Earth Spiritual Qi from the outside world into the spiritual sea little by little.

But after that spiritual power vortex was condensed in his spiritual sea, everything changed.

The swirling of the spiritual power vortex produced suction, and with his qi refining technique, it was several times faster to extract the rich heaven and earth spiritual energy nearby.

He tried, not using the Qi Refining Technique, not cultivating, but found that the spiritual power vortex in the Spirit Sea was still spinning.

It's just that without his subjective guidance and the cooperation of his Qi Refining Technique, the speed of the spiritual power vortex of the Spirit Sea was obviously several times slower.

But even so, the vortex of spiritual power from his spiritual sea was still slowly absorbing the spiritual energy of heaven and earth.

This made him suddenly realize that in the future, even if he didn't cultivate and didn't sit quietly and run the Qi Refining Technique, his Spirit Sea would still be in a state of gathering the spiritual energy of heaven and earth due to the existence of that spiritual power vortex.

Whether he was eating, sleeping, or fighting with people, as long as the spiritual power vortex did not stop swirling, he would continuously gather the spiritual energy of heaven and earth.

"Acquired Realm! Could it be that this is the essential difference between the Acquired Realm and the Qi Refining Technique?"

At this moment, he felt the change in himself, and without any guidance from anyone, he also seemed to understand the key.

Immediately, he clearly realized that the formation of the spiritual power vortex in the spiritual sea seemed to be ...... It is the biggest difference between the Qi Refining Technique and the Acquired Realm.

It can even be said that once a spiritual power vortex is formed in the Spirit Sea, it means that a Qi Refiner has stepped from the lowest level of Qi Refining Realm to the Acquired Realm!

"The day after tomorrow! This should be the acquired realm!"

He woke up in an instant, and then ran the Qi Refining Technique again, guiding with his own consciousness to speed up the rotation of the spiritual power vortex.

The next moment, he felt the rotation of the spiritual power vortex, which suddenly accelerated several times, and also felt the suction from the heart of the spiritual power vortex, which strengthened several times.

The speed at which he gathered the aura of heaven and earth, and because of this, suddenly became extremely fast!

"Wonderful!"

He was ecstatic, he could no longer feel any discomfort in his body, and found that the original peaceful spiritual sea, because of the formation of the spiritual power vortex, seemed to have changed from lifelessness to vitality all of a sudden.

Linghai, due to the formation of the spiritual power vortex, seems to have been given vitality, and the speed at which he gathers the spiritual energy of heaven and earth in the future will increase several times.

Even if he didn't cultivate in the future, his spiritual sea would always pull the nearby heaven and earth spiritual qi and slowly gather towards the spiritual sea.

This is the biggest change in the acquired realm and the qi refining technique!

"This ...... Even if you break through?"

After figuring out the key, he was still a little dazed, he passed through the rich heaven and earth aura at the end of the stone path, and a large amount of spiritual sea merged into the spiritual sea for a while, and suddenly felt a little difficult to breathe.

Then, he felt the stone under his ass again, and it became hot and hot.

He subconsciously opened his eyes.

Immediately, he found that at the end of the stone path, the surrounding stone walls seemed to have turned into red-hot flame crystals, all emitting amazing flame energy.

Staying here, he was completely unaware of the changes in the outside world, and his body was dripping with sweat, and he was gradually unable to withstand the high temperature here.

He looked sharply at the Yanlong Armor and saw that the Yanlong Armor was resting on the crystal-like ribbon, still absorbing wisps of flame threads.

He also saw that in the molten pool below, the huge figure of the Earth Flame Beast was still frantically gathering the Flame Energy with some unknown bloodline talent.

"The Flame Dragon Armor and the Earth Flame Beast have a tacit understanding, and they want to attack inside and outside together to break the ban from the ribbon. Once the ban is broken, the magma flames in the molten pool below will surely gush out wildly, and will rush through those stone paths to the outside world. ”

"At that time, I will be the first to suffer from the molten pool!"

"Outside, An Shiyi, who was waiting for me in the place where I left, and maybe everyone else, will be drowned in the magma flames, and there will be no escape!"

Thinking of this, his face changed unpredictably, and he suddenly made a decision.

"When you get everything you want, please...... Back to me. He released a wisp of spiritual consciousness to the Yanlong armor and expressed his thoughts.

Then, he finally stopped staying and immediately returned the way he came.

At this point, he knew that if he insisted on staying, once the Flame Dragon Armor and the Earth Flame Beast joined forces to break the ban, and when those magma flames erupted, he would inevitably turn into blood in an instant.

If he could see hope, and knew that staying would help Yanlong Armor, and that he could get out of trouble before things got out of hand, he would continue to wait.

But now, from all kinds of clues, he already knows the upcoming results.

He no longer waits in vain.

"Whew!"

Just as he galloped away and returned along the same path, the suspended flame dragon armor seemed to sense his thoughts, and suddenly released a blazing fire.

It's a pity that he can't see it anymore, and he just wants to stay away as soon as possible and bring An Shiyi and the others out of the stone cave in the low mountain together.

On the way back, some of the stone paths that were forcibly chiseled by Yanlong Armor were blocked, but fortunately, all that blocked the stone paths were bursting gravel, and he had a little effort, but he still slowly walked towards the surface from those blocked stone paths.

"Nie Tian, Nie Tian!"

I don't know how long later, he suddenly heard An Shiyi's anxious shout.

His heart warmed, and he recognized An Shiyi's voice and continued to gallop towards the surface.

"Boom!"

After half a ring, he blasted open a blocked stone passage and suddenly appeared in front of An Shiyi.

"Nie Tian, where have you gone?" An Shiyi was startled at first, but after finding out that it was him, she breathed a sigh of relief and said, "I came to look for you, but when I got here, I found that there was no way." I ......"

Without waiting for her to finish explaining, Nie Tian suddenly grabbed her jade arm, took her out, and shouted, "Don't say it, get out of here!"

Nie Tian saw that the place where An Shiyi stayed was the starting point for Yanlong Armor to go to the center of the earth.

The chiseling of the Yanlong armor caused the new passage that had been unblocked for a while again.

An Shiyi rushed here and found that there was no way, but there was still no trace of him, so she could only shout loudly, hoping that he could hear.

"What happened?" An Shiyi didn't resist, let him drag herself, follow his pace, and rush outside.

She is higher and deeper than Nie Tian's realm, so when she is galloping, she still has the strength to speak.

But Nie Tian, who was bent on getting out as soon as possible, had already exerted all his strength, and could no longer explain anything.

After asking a few words, An Shiyi also stopped asking after seeing that Nie Tian did not answer, and just buried her head in the road with him, looking at his resolute side face from time to time, and her bright eyes were slightly in a trance.

"It's really grown up......" An Shiyi muttered quietly.

After half a ring, the bright light in front of the dark stone path was highlighted.

"You're back. Pan Tao's anxious voice suddenly came.

Nie Tian's heart was relieved, knowing that at this moment, the change in the center of the earth had not started, and he could rush here, and everyone would at least not be swallowed up by the lava flames without warning.

"Get out of the cave!" he said.

"You kid!" Pan Tao scolded, walked out of the stone cave while scolding, and said, "You think we want to stay in this hellish place?

Jiang Lingzhu and Ye Gumo were not polite, they both scolded him, saying that he was nonsense and caused everyone to be unlucky.

Nie Tian, who came out of the stone cave, let them vent his dissatisfaction, but his face was full of smiles.

He saw that Zheng Bin and Han Xin were no longer among the crowd.

The people who remained, no matter how they cursed him, did not abandon him, knowing that he was willful, they all waited for him to the end.

These people are what he really values and is moved by.
