He cultivated in one day, and the spiritual energy consumed was more than a month's savings of the Blue Dragon Great Array. Only in the Emperor Cave Mansion, the spiritual veins that have accumulated thousands of years of qi can satisfy Chu Ling's penance.

But even so, the spiritual liquid in the spiritual pool slowly declined to a degree visible to the naked eye.

Xie Yan raised his eyes and looked at the original spirit pool more than ten meters deep. Now it is about seven or eight meters less, and nearly half of the spiritual liquid has been consumed by Chu Ling.

"What realm has the sect master cultivated to? In one year, he has refined so much aura?"

Xie Yan was stunned.

During the year.

Xie Yan was also practicing in the Emperor Saint Cave Mansion, and Chu Ling had left him enough Xuanling Pill, so he didn't need to worry about eating and drinking at all. When Chu Ling was cultivating, Xie Yan was also contemplating the "Nine Separation Sword Sutra" and working hard to cultivate.

Now the two bundles of white on his sideburns have all turned black, his skin is shining with a crystal clear luster, and the whole person's aura is getting stronger and stronger, reaching the peak of the middle stage of Lingzun. Xie Yan felt that he was only half a step away from the late stage of Lingzun. This year was enough time to outweigh his ten years of penance.

And this is just the aura that overflows when Chu Ling is cultivating. The aura that Chu Ling absorbed was probably more than a hundred times that of Xie Yan, how terrifying and terrifying was that?

Xie Yan couldn't imagine it.

"Boom. ”

At this moment, a vast aura poured out from Chu Ling's body, filling the entire stone room. In front of this breath, even Xie Yan felt that he couldn't bear it, and he couldn't help but retreat.

"Is this a breakthrough?But what realm has the sect master broken through?Is it the peak of the Spirit Venerable, or the realm of the Emperor Saint?"

Xie Yan's expression changed slightly.

I only felt that Chu Ling in front of him was much more terrifying than before, and his qi was so powerful that he even surpassed Zhang Ji'an, Xu Ce and others he had seen, and reached an incredible realm.

But this was just the beginning, and immediately after, something that surprised Xie Yan even more.

"Bang bang bang. ”

One after another visions emerged from Chu Ling's body.

In Chu Ling's eyes, two golden flames emerged. These two golden flames were even more vigorous than before, and at this time, they were as big as a child's fist, condensed to the extreme, and even the space seemed to be burned quickly.

Then, a golden flame armor appeared on Chu Ling's body again, and this armor looked more majestic and majestic, like a general of ten thousand armies, with unrivaled power.

But what scared Xie Yan the most was an illusory image.

This phantom, with a vague and invisible appearance, wears twelve crowns, wears a wide imperial robe, extremely majestic, and its feet seem to be stepping into time, changing in time and space.

Xie Yan saw with his own eyes that a green vine approached the emperor's shadow, and then it quickly turned yellow and withered and rotted at a degree visible to the naked eye. It's as if with a flick of your fingers, you have passed.

"What is this?"

Xie Yan gasped.

The Flame Twin Pupils, the Golden Flame Armor, and the Phantom of the Emperor's Robe, and finally the Demon Shadow.

"Whew. ”

The violent aura on Chu Ling's body gradually stabilized.

Xie Yan couldn't help but show joy on his face, which meant that Chu Ling had successfully broken through, and then he could officially get out of the customs after stabilizing the realm.

Although he was used to penance, he still felt a little unbearable to stay in this valley for a year. If Chu Ling's cultivation breaks through, they will be able to go out.

But five days, ten days, and a month passed.

Chu Ling didn't have the slightest posture to get out of the pass, but the aura on his body gradually rose, and he walked forward steadily.

"The master of the door wants to break through two realms in one breath?"

Xie Yan was already dumbfounded at this time.

Chu Ling's previous breakthrough was earth-shattering. It is conceivable that once he is out of the customs, he will be able to push the world sideways. Even Zhang Ji'an, Xu Ce and others may not be his opponents. But now Chu Ling didn't stop, and he had to continue to break through. Then when he succeeds in breaking through again, won't he be able to fight the Emperor Saint?

Xie Yan didn't dare to imagine how powerful Chu Ling would be at that time.

I'm afraid that Xu Fei's life-burning blood sword technique can't even cut the corners of Chu Ling's clothes.

Thinking like this, Xie Yan watched as day by day, Chu Ling's qi became stronger and stronger, and in the end, the entire Emperor Saint Cave Mansion was filled with Chu Ling's huge qi engine. Xie Yan was directly forced out of the cave and cultivated in the valley. Otherwise, as long as he was in the cave mansion, he would have to raise his true qi, and he would have to fight against Chu Ling's qi all the time, and he would not be able to cultivate at all.

One month, two months, three months...

In the blink of an eye, another half a year has passed.

From Chu Ling to the Valley of No Return, a year and a half have passed at this time.

On this day, Xie Yan continued to practice swords in the valley.

"Whoosh. ”

An ebony wooden sword was controlled by him, flying in the air, extremely fast, and pulling out a terrible sound of breaking the air, like a black light. With a wave of Xie Yan's sword.

"Boom. ”

The black light split on the mountain wall, and it actually forcibly split the mountain wall into a crack more than ten meters long.

"Today, the Nine Separation Sword Sutra has finally become small. ”

Xie Yan withdrew the ebony flying sword, and breathed a sigh of relief in his heart.

The more he studied, the more he felt the breadth and profundity of the Nine Separation Sword Sutra, which was definitely a supreme sword book that pointed directly at the heavens. In the past year and a half of his cultivation, not only did he not break through to the late stage of the Spirit Venerable, but instead fell to the early stage of the Spirit Venerable.

But the more Xie Yan's true qi is condensed, the more it is transformed into the Nine Separation Sword Yuan in the "Nine Separation Sword Sutra". At this time, the power of Xie Yan's casual blow was comparable to that of his peak. If Chu Ling was here, he would know that Xie Yan was already a Spirit Venerable Realm immortal cultivator in the strict sense. According to the conversion of cultivation, it belongs to the early stage of the Lingzun realm.

It's just that in the early stage of his Spirit Venerable Realm, compared to Chu Ling's, the gap is too far, at least two or three times worse, not to mention, now Chu Ling has broken through to the middle stage of the Spirit Venerable Realm, and continues to break through.

"This Nine Separation Sword Sutra is already terrifying, what kind of vast Heavenly Immortal Secret Book is the cultivation method of that sect master?"

Xie Yan didn't dare to imagine.

At this time, he suddenly felt that in the cave, there was a surging momentum. This momentum is so huge that it rushes straight up to the nine heavens, stirring up the clouds and mist above the valley of no return, and they are all boiling.

"Breakthrough again?"

Xie Yan's face changed wildly.

I only felt that this momentum was so powerful that it had never been seen before, and it seemed to be about to break into some immeasurable realm. Xie Yan felt that as long as he entered that realm, Chu Ling's strength would reach an incomparably terrifying realm, comparable to that of the Emperor Saint.

But what made Xie Yan puzzled was that Chu Ling's aura seemed to linger in front of that realm, and he actually withdrew it.

"What's going on?"

Xie Yan's face was full of doubts.

At this time, the qi had been completely withdrawn, and when Xie Yan stepped into the cave mansion, he saw Chu Ling sitting cross-legged in the cultivation room, and the spirit pool in front of him, which was more than ten meters deep, had dried up, leaving only a thin layer of ground. Fortunately, there is a spring, which is still flowing out of the spiritual liquid, just to fill the entire pool, it will take at least a thousand years.
