Liu Xu caught more than 100 Heavenly Blessing Qi in a row, and the Black and White River in the Soul Cultivation Building became stronger and stronger, and it was incomparable.

However, as more Gang Qi was collected, the third floor of the Soul Cultivation Building, which was about to overflow, was completely filled with Gang Qi and escaped to the outside of the body, which was only the result of refining a small half of Gang Qi.

I saw that he was surrounded by evil, and his body seemed to weigh more than 10,000 catties, even with his body equivalent to the second layer of body refining, it was a little unbearable, fortunately, he was supported by the iron armor star shuttle, otherwise he might fall down directly.

Moreover, the soul has to recite the Demon Sutra all the time, and there is no time to distract the mind from refining the Gang Qi, which makes the accumulation more and more, and the more miserable it is, which invisibly increases the difficulty.

"What should I do? I'm afraid that if I can't wait for the completion of refining Gang, my physical body will not be able to bear it first! Even if I break through to the second and third layers of Tiangang atmosphere, there will be no change, and I will only make my Gang Qi thicker and stronger, and the true qi in my body will become more and more. ”

Liu Xu quickly thought about countermeasures in his heart.

After thinking about it, "If you break through the Tiangang atmosphere above the fourth layer, absorb the qi of those spiritual cloud beasts, and further integrate the Gang qi into one place, maybe you can compress it to the extreme." However, the Tiangang atmosphere bursts, and the ironclad star shuttle may not be able to withstand it!"

Liu Xu fell into a dilemma, ordinary people looked at him with a heavier spirit, but when they came to him, they became a burden.

"Well, if you can't get through this little pass, and you can't talk about the Great Dao of Immortality, I'll give it a try, what is the taste of the higher Tiangang atmosphere? ”

Liu Xu shouted loudly, urging Shamoro to go higher.

Between every two layers of Tiangang atmosphere, most of them are hundreds of zhang apart, there is a faint layer of invisible boundaries, as soon as the star shuttle side breaks into the second layer, it feels ten times more violent than just now, accompanied by the sound of rolling and whistling, like thunder, rumbling, the speed is several times faster than the first layer, blowing the ironclad star shuttle to the east and west.

"After refining the qi into Gang, the sword qi will emit a thunder sound, and the speed is extremely fast, could it be that the sword qi thunder sound comes from this?"

Liu Xu wanted to capture the cloud beast, but he didn't stay at the second layer, and broke through to the third and fourth layers with the iron-armored star shuttle before he stood up.

Looking at the sky overhead, this fourth layer of Tiangang atmosphere is different from the first three layers, if the first three layers are compared to a grumpy man, always trying to ravage all intruders, the fourth layer is a quiet beautiful man, quietly watching you come.

Liu Xu knew that the fourth layer seemed to be calm, but it was an undercurrent surging, lurking in countless crises, because the ironclad star shuttle under his feet had begun to tremble, no matter how he urged, it actually seemed to take root, and it was also still.

Liu Xu sighed secretly, "That's it, these spirits on the left and right also have to be refined, so leave Xingshuo here, otherwise with their cultivation mana, they will be torn to pieces in an instant." ”

Called the clam Yongshou to the front, briefly ordered a few words, don't go out and so on, and then used the true light gourd to protect himself, and the water cloud yarn unfolded into a white cloud of several acres in size, directly stepping into the outside world, exposing himself to the gangqi.

Suddenly, because his body was too heavy, he seemed to cast a jack pendant, and directly pressed the water cloud yarn downward, and when he urged the mana to be stable, he was blown by countless winds of rising wind, and like an arrow from the string, from the bottom to the top, it directly broke into the fourth layer.

The talisman smoke was squeezed so that it made a rattling sound, which made the roots of the teeth sour.

Liu Xu has a resolute temperament, a stable Dao heart, and many contingency means in his body, suddenly from the violent third layer to the quiet fourth floor, although it seems calm, he does not dare to be careless.

After looking around, I found that the Gang Qi in the fourth layer was really different from the first three layers, although the Gang Qi did not generate cloud beasts, but it also seemed to have a little spirituality, and a very small Gang Qi vaguely opened its ears and eyes, and when I saw Liu Xu coming up, not only did not hit it, but turned around and disappeared.

Liu Xuxin said that it was really right, these gangqi seemed to be tiny, but in fact, after thousands of years, from a mass of 100 acres, compressed and smelted to the extreme, after giving birth to a little spirituality, it could be condensed into the thickness of chopsticks, if no one bothered, after tens of thousands of years, it might be able to turn into a cloud beast, and the power is incomparable.

Liu Xu saw that he was happy and found hope to solve his own problem, so he first aimed at a Zhenyougang that was an inch long, like a tadpole with a big head and a small tail.

This True Gang is extremely flexible, Liu Xu just grabbed him with his silk winding hand, and was instantly frozen into a lump of ice, shattered, as if laughing at him, flicked his tail, and disappeared.

Liu Xu was angry and funny, glanced around, and found that there was no real Yougang except for this tadpole, so he had to look patiently for it, gritting his teeth in his heart, "Okay, you little tadpole, since you dare to laugh at this Dao Master, I will be on the bar with you today, and I have to refine you." ”

Yun Lian Gang Xindian carefully sensed, and actually found that there was a wisp of breath in the water cloud veil under his feet, Liu Xu laughed, "It is worthy of being a spiritual thing that has just been born, and the IQ is worrying, since there is a road in heaven and you don't go to hell, you break in without a door, then the Dao master will laugh and accept it!"

At that moment, he rolled up the clouds under his feet, and the water cloud yarn immediately shrank to the size of a foot, Liu Xu turned around and stabbed it in, opened his mouth violently, and grabbed him.

After swallowing this Zhenyougang, Liu Xu took his heart as a guide and transported him to the Soul Cultivation Building, and immediately it was like a spark into the oil pot, and the overflowing Gang Qi began to boil and burn, and after a quarter of an hour, it all condensed into one place, turned into the size of a grain of rice, and was swallowed by the tadpole.

Liu Xu didn't waste any time, at this time, the soul nourishing building was mostly empty, and he directly included the outside of the body, and after all of them were swallowed by the tadpole, his body immediately relaxed a lot, and it was no longer as heavy as before.

This fourth layer of Gang Qi, each of which is hundreds of times more pure than the first three layers, after Liu Xu refined more than 100 of them, the Soul Cultivation Building in his body overflowed again, and the original gray Gang Qi appeared as white as frost and snow, exuding a chill.

The fourth layer of Tiangang atmosphere is the thinnest in the Nine Heavens Yuangang, Liu Xu has been refining Gang for seven or eight days, and he can no longer find a spiritual True Blessing Gang, most of them are hundreds of zhang long, and they are huge.

"It seems that the upper layers of this are not successful, if you want to refine it in one fell swoop, I am afraid that you will have to refine a cloud beast!" Looking at the soul cultivation building that was overflowing again, Liu Xu sighed in his heart.

At this time, he was full of confidence, and he used the Shadowless Escape Method, and turned the power of the Gang Sha that had been refined, and his body immediately disappeared into the Gangfeng, floating with the rising Gang Qi Flow, with his own escape technique, it was already much faster than Shui Yun Sha.

After re-refining on the fourth layer, Liu Xu's true qi was finally light and comfortable, and he was able to fly with his own mana without the help of Shui Yun Veil.
