The optimized "Yijin Sutra" is indeed more suitable for people to practice, and in less than a month, Mu Xiaotian has reached the ninth level of Qi cultivation and can break through to the stage of foundation building at any time.

But now he has a new idea, the "Yijin Sutra" can be optimized, is it possible to optimize the practice of qi, can the sea of qi, meridians, etc. be optimized? If he could, he would rewrite his current way of cultivating, and a whole new world would open up in front of him.

He was reincarnated as a human, so he naturally didn't want to go through the trajectory of his previous life again, how boring it must be, the existence of the alien fire seed made everything possible. He was determined to tap into the potential of the Alien Fire Seed in this life, allowing him to create a realm that no one had ever reached before.

His qi sea has now been squeezed by the aura, and if he doesn't upgrade to the foundation building realm, the qi sea is in danger of being squeezed out, and the top priority is to see if the qi sea can be optimized.

Now the alien fire seed has turned light green, it looks green and green, and it seems to have a trace of spirituality, Mu Xiaotian let the alien fire seed swim along the edge of the sea of qi to see if he can broaden the sea of qi, the alien fire seed is floating in the sea of qi while absorbing the crowded aura, and the sea of qi that was originally uncomfortably rising is relaxed again, this guy seems to be upgrading?

Mu Xiaotian didn't care about optimizing the sea of qi, and looked at the alien fire seed tightly, at this time, the alien fire seed in the sea of qi had stopped swimming, but was slowly rotating and speeding up. The surrounding aura also rotated rapidly with the alien fire seeds, becoming thinner and thinner as it turned, and the originally crowded aura was sucked to the ground. The Alien Flame Seed had turned into an illusion, and it was still spinning at the moment.

Mu Xiaotian was a little nervous, what is this guy playing? Upgrading is not like upgrading, purification is not like purification......

Suddenly, he felt that something was wrong, with the rotation of the alien fire seed, his aura was sucked away, and his qi training level was also declining rapidly, the qi training was complete, the peak of qi training, and the ninth level of qi training...... At the first level of Qi training, he wanted to make the Alien Fire Seed stop, but the Alien Flame Seed didn't seem to pay attention, and even his own mind was bounced away.

Anyway, it's already like this, let's treat a dead horse as a live horse doctor! It's a big deal to practice it again and see what this guy is going to do now. Can you still waste yourself?

What are you afraid of, the alien fire seed directly shattered the sea of qi and traveled along the meridians, and all the tendons and veins where it passed were broken and shattered, and he had no grudge against this alien fire seed, how could he put himself in the rhythm of death?

The pain of broken meridians made his nerves foggy, and his body went limp......

When he woke up, there was a pain all over his body, he felt that his eyes had become sharp, and his mind subconsciously looked at the sea of qi, and couldn't help but be pleasantly surprised, the original broken sea of qi not only expanded a lot, but also divided into nine sea of qi, five of which flowed with different colors of aura, with obvious attributes of the five elements, it seems that the nine sea of qi correspond to different attributes, and the other four sea of qi are still in a gray state, obviously not activated, maybe these attributes are special after all, or relatively rare, After all, the attributes of gold, wood, water, fire, and earth are rare. It seems that the alien fire seed not only purifies the aura, but also classifies the attributes of the aura. Looking at the nine independent Qi Seas again, it is obvious that he can be upgraded individually.

It seems that he is wrong to blame the Alien Fire Seed, this guy is really too rebellious, and then look at the meridians destroyed by the Alien Fire Seed, not only restored to the original, but also obviously expanded and strengthened, and even some of the meridians that were not opened before have been opened, making the operation of the aura smoother.

Although the realm is only at the level of Qi cultivation, why should it be cared about? Is it difficult to practice Qi to perfection? With the optimized "Yijin Sutra", the purification of the different fire seeds that have been significantly upgraded and greener, and the meridians that have been broadened and opened up, cultivation is a simple matter.

As expected, the operation of the "Yijin Sutra" again made the surrounding aura quickly converge towards him, and the scope became larger and larger, looking from the sky, like a huge cyclone.

Level 2 ...... Qi Training Level 3 ...... Level 4 ......

Mu Xiaotian's level quickly and steadily moved towards the perfection of Qi training. It's just that due to the different attributes of the aura here, the upgrade speed of the five qi seas is different, the speed of the fire attribute, the earth attribute, and the wood attribute is the fastest, and the gold and water are a little slower.

On this day, he looked at the three Qi Seas that had already achieved Great Perfection, and was still struggling with whether to wait for the Five Elements to break through together or a single attribute, when the Alien Fire Seed that had fallen asleep due to the upgrade suddenly woke up, kept jumping, and seemed a little excited, jumping out of Mu Xiaotian's body directly, and slowly drifting forward.

Mu Xiaotian knew that this guy was very rebellious, and he must have found something amazing, so he followed curiously.

After a while, a green shadow stopped on the edge of a cliff, Mu Xiaotian looked down, the fog was vast, even if his eyes were transformed by the alien fire seed, he still couldn't clear what was underneath. He turned his head and asked, "There's something down there?"

The Alien Flame Seed seemed to understand his words, and it shook twice in front of his eyes, and then floated down the cliff.

Mu Xiaotian gritted his teeth, and slowly climbed down with some mountain vines from the side, but fortunately, he was successful in practicing qi, and his body was light and agile, but he could also keep up with the speed of the different fire seeds.

A few hundred meters below the cliff, two boulders appeared, with a small gap between the two boulders, just enough for one person to pass sideways.

A green shadow flew in, Mu Xiaotian hurriedly followed, the first section inside was a very narrow wall, the narrowest was enough for one person to squeeze through. The back is getting wider and wider, and a green light leads the way in front, and you can vaguely see the situation under your feet.

At a corner, some bright light suddenly appeared, and a golden low-level alien fire floated in the air, and the alien flame seed didn't stop, floating directly forward.

There are low-level different fires along the road, this is obviously a different fire vein, the further you go in, the higher the level of different fires appears, Mu Xiaotian is a little moved, but the different fire seeds are very disdainful, and they keep floating forward, without even the slightest intention of staying, he has to follow behind.

After walking for a few miles, the eyes suddenly opened up, an open space with a radius of hundreds of meters densely filled with strange fires, around a stone platform in the center, five different colors of different fires in the middle of the stone platform are entangled with each other, and a dragon shape slowly appears in the entanglement of five different fires.
