Hearing the promise of the middle-aged man in front of them, two of them secretly breathed a sigh of relief.

"This left protector, then congratulations to Dean Liu in advance for obtaining this earth-centered flame. Although the left and right protectors cannot subdue this earth-centered flame, they know a lot about the origin and power of this flame. If Dean Liu hadn't agreed to our request, we wouldn't have said it. ”

Looking at the energy barrier in front of him, Zuo Protector continued: "This Earth-Heart Flame is an ordinary flame in the magma, just because it absorbed a wisp of Heaven and Earth C-Fire Qi to open the spiritual wisdom, and then took the initiative to absorb the surrounding fire aura, constantly growing itself, and after tens of thousands of years of accumulation, it finally evolved into this Earth-Center Fire!"

Dean Liu was overjoyed, he didn't expect the flames within this energy barrier to have such a origin! However, he sighed again, he was about to catch this geocentric flame, but he didn't expect that this geocentric flames had already opened his spiritual wisdom and escaped at a critical moment.

After that experience, this geocentric flame was careful every time it absorbed the fire aura in the magma.

This time, the original preparation was foolproof, trapping the geocentric flame, but I didn't expect this geocentric flames to be able to control this underground magma, and the entire magma river was temporarily controlled by it. Using the inexhaustible fire aura in the magma river, a huge ball of light was formed to wrap itself.

This geocentric flame absorbs the fire aura in the magma river, not only maintaining the consumption of this huge ball of light, but also increasing the thickness of this ball of light!

Originally, such a ball of light could be formed without restrictions, but each of these four people took out the pre-assigned formation flag and arranged a set of fifth-level formation "Decishui Formation".

This formation is the Yin Water attribute, and the Earth's Core Flame is Yang Fire, so the effect of this formation in restraining the Earth's Heart Fire is greatly increased.

Although the geocentric flame has opened the spiritual intelligence, but this formation is a fifth-level formation, at this time, the geocentric flames can barely resist the fourth-level formation at most, and finally the ability of the geocentric flames to absorb the fire aura in the magma river is greatly reduced, and the speed of absorbing the fire aura is only half of the usual, and this absorption speed is a bit unable to keep up with the consumption rate of maintaining the light ball barrier.

The Earth's Core Flame also knew that only by releasing the fire aura that he had absorbed before could he temporarily avoid being caught by the humans in front of him.

However, I don't know what's going on, the speed at which the fire aura was originally absorbed slowed down again, from one-half to one-quarter. This can make the fire in the center of the earth so anxious that it will run around in the light ball barrier, and the light ball barrier will become unstable.

The Earth's Core Flame can only increase the fire aura absorbed before the release to maintain the stability of the light ball barrier.

At this time, the geocentric flame also knew that if he didn't do this, he would definitely be subdued by the people in front of him. As the king of this underground surging magma river, of course, he has the arrogance of a king, and it is absolutely impossible to be subdued by others!

Just when the volley martial soul absorbed a large amount of underground fire aura, the flames in all the alchemy rooms became much weaker, and this sudden change affected the elders and disciples who were alchemizing: those with reluctant strength were basically fried furnaces, those with good strength barely stabilized the situation, those who were lucky practiced inferior pills, and those who were unlucky directly became waste pills, and only those elders with rich experience in alchemy successfully refined pills. This caused many elders and disciples to go out one after another to see what was going on.

When everyone walked out of the alchemy room, they found that everyone was in this situation, and the elders also discussed, and one of the disciples said, "Could it be that there are too many people using it, and the flames are not enough, so the flames have become weaker?"

After all, there has never been a situation where all the alchemy rooms have been used before, and at most even half of the alchemy rooms have not been used, so everyone has entered their respective alchemy rooms and started alchemy.

However, Ling Kong was still selflessly cooperating with the martial soul to absorb the fire aura under the formation, and he didn't expect that his martial soul's absorption of the fire aura would have so many effects.

As time passed, more and more fire aura was absorbed, and the flame whirlwind in the underground space became thicker and thicker, from the thickness of the fingers at the beginning, to the thickness of the fist now.

Just as the volley continued to cooperate with the martial soul to absorb the underground fire aura, another root beard grew from the root of the martial soul, and the fist-thick flame whirlwind became stronger and stronger with the addition of the newly grown roots. Not to mention the fire aura that permeated the air, the fire aura in the area where the martial soul was located was completely like a demon, and it was running frantically in the direction of the martial soul!

As the martial soul absorbed a large amount of fire aura, the roots that had just grown gradually grew up, and finally grew into three-zhang long roots.

Ling Kong was ecstatic, and originally wanted to continue to absorb fire aura with the martial soul here, but after estimating the time, it was time to leave. So Ling Kong left Elder Zhao's alchemy room a little reluctantly.

On the way back, Ling Kong found that many disciples were silent and quickly went to the living area. Seeing that everyone was like this, Ling Kong didn't ask anything, and went to the room where he was resting.

In the underground space, the originally unstable light ball barrier suddenly became stable, and the geocentric flame immediately accelerated the absorption of the surrounding fire aura, and the light ball barrier gradually thickened as the geocentric flame absorbed a large amount of fire aura.

Seeing such a situation, the four people in front of the light ball barrier all looked stunned. The barrier of light balls that were about to dissipate gradually thickened.

And Dean Liu, who originally planned to subdue the flames in the center of the earth, is now also on the verge of going berserk, Dean Liu suppressed his anger, walked to the side alone, and meditated. The other three didn't say much, and the three of them dispersed, observing the surrounding situation while recovering the true qi consumed by maintaining the formation.

When Ling Kong returned to his room, there was always a question surrounding Ling Kong, after all, just now in the alchemy room, the martial soul had absorbed so much fire aura, how could he still be in the early stage of Qi training, and there was no sign of breakthrough at all. Although the martial soul has grown new roots, there is usually no sign of a breakthrough, at most, it feels that the true qi in the body is full, is this the early stage of qi training for a lifetime?

Ling Kong remembered at this time that he remembered the two mysterious exercises he had obtained before, and it turned out that Ling Kong had cultivated a little except when he had just obtained these two mysterious exercises, and then he had not practiced until now.

So Ling Kong first familiarized himself with the mysterious exercises that can increase his cultivation, and then sat cross-legged on the bed, put his hands on his knees, entered a state of concentration, and began to practice this mysterious exercise.
