In the middle of the sixth layer of his qi training, he is actually equivalent to the seventh layer of other people's qi training, and he is already the strength of the late stage of qi training, his ability to kill enemies beyond the level, coupled with the fact that the Yantian Holy Technique needs to absorb several times the aura of others to cultivate, the resulting ability to kill enemies at the next level makes Yang Nan look forward to it.

"Can I fight with Xue Wuyan, who is already in the Heavenly Venerable Realm and is equivalent to the Dragon Realm of the Cultivator." Yang Nan thought to himself.

The next great realm of the Qi Cultivation Realm is the Dragon Transformation Realm, and then the Jindan Realm, the martial artist is Xuan Qi after all, inferior to the True Qi in terms of quality, with the Reverse Heaven of the Heavenly Sacred Technique, he thinks that he still has hope of defeating Xue Wuyan.

At a glance, Yang Nan found that after the spiritual spring was absorbed, there were more than a dozen bright crystals at the bottom of the spring pool, which looked crystal clear and transparent, making people's hearts clear.

"Spirit crystals?" Yang Nan's heart became excited again, the spirit crystal is a crystal formed by the spirit spring, and it is more refined, and the spiritual energy contained in these spirit crystals may not be less than the spiritual energy spring just now.

Yang Nan immediately stepped forward to pick up the spirit crystals one by one, he checked it, there were thirteen in total, and while the passage for promotion was opened, Yang Nan hurriedly sat down again, holding the spirit crystals in his hands and continuing to cultivate.

An hour later, the barrier of the middle stage of the sixth layer of qi training was broken through again, and he successfully advanced to the late stage of the sixth layer of qi training, and his cultivation was still gradually climbing upward.

One by one, the spirit crystals turned into ashes in his hands, and under the infusion of rich spiritual energy, his cultivation finally came to the consummation of the sixth layer of Qi training, and he felt that there was hope to break through the seventh layer of Qi training, Yang Nan immediately subdued the Qi Cultivation Pill that was used to break through the barriers to promotion.

Suddenly, the spiritual energy in the meridians surged, and he tried to impact the barrier of the seventh layer of Qi training, but he felt that it was still lacking, and directly took out two Qi Cultivation Pills and swallowed them.

Suddenly, a more abundant aura washed over his eight and twelve meridians, and the blood-colored true qi in Danhu Lake became more condensed, and under the tempering of the aura, the meridians were more wide and tough.

Silently running the exercises, and after the body adapted to the riot of the aura and stabilized, Yang Nan immediately guided the true qi in the meridians to attack the barrier of the seventh layer of qi cultivation again.

The seventh layer of Qi training is different from the sixth layer of Qi training, the seventh layer already belongs to the late stage of Qi training, and the strength and the middle stage are not the same, and the barriers to promotion are more tenacious and more difficult.

"Boom!" The aura impacted on the barrier of promotion, Yang Nan felt that the sea of consciousness roared, as if he himself was resonating with heaven and earth, but unfortunately, the barrier to promotion was only broken open a narrow gap.

Yang Nan was not discouraged, let alone stagnant, gathered his true qi and continued to attack the barrier of promotion, the layer of diaphragm was like a door that was about to open, it seemed that it would be opened at any time, but it couldn't be opened, as if it was a little bit of strength.

"Damn, I still have to waste Lao Tzu's Qi Cultivation Pill!"

It is impossible for an ordinary person to advance to the seventh level of Qi cultivation in this situation, but he has an advantage that others do not have, he is a Dan Master, using the Stone Flower Lock, he has refined a total of twelve Qi Cultivation Pills.

For his friends and women, he used three, and he still had nine, as long as he could advance, where would he care about the consumption of the pill, without hesitation, Yang Nan swallowed a Peiqi Pill again.

The more violent aura was surging and boiling in the meridians, and his meridians were painful, where could Yang Nan take care of these, if he couldn't advance at such a cost, it would be more difficult to advance next time, and he didn't know how long he would stay at the sixth layer of qi training, so Yang Nan didn't care about the pain, and immediately used the violent aura to attack the barrier of promotion again.

Rumble!

There was a roar in his body, as if a door was pushed open, the aura surged in, and the raging aura instantly became smooth and smooth, and he felt that he had entered a new realm, and a new and broader feeling filled his spiritual sense, giving him a feeling of flapping his wings.

Yang Nan was busy running the exercises and continued to stabilize his cultivation.

Before he knew it, a day had passed, and when he opened his eyes again, a happy smile appeared on his face, and he had successfully advanced to the seventh level of Qi training.

Punching out the clear water trick to clean his body, Yang Nan checked the spirit crystals, and couldn't help but smile bitterly, nine of the thirteen spirit crystals were consumed by him, and only four were left, and the Pei Qi Pill directly consumed four.

Although there are a lot of resources consumed, but feeling the huge improvement in his own strength, Yang Nan thinks that it is definitely worth it, not to mention the four Qi Cultivation Pills, as long as he can be promoted, he will not hesitate to go down in full service.

Yang Nan carefully put the remaining four spirit crystals into the ring and kept them for the women to use to break through the realm at a critical moment.

Standing up, the joy of promotion made Yang Nan can't help but let out a long howl, he looked around for the rabbit, and wanted to say two words of thanks to it, but unfortunately the beautiful snow rabbit needless to say was not here, but was also scared away by his long howl.

Yang Nan observed this aura spring again, this should be a renewable aura spring, see that the traces have reached half a pool, but this place is located in the barren mountains and snow, if no one finds it, it will escape after a long time.

"I don't know when the next time the aura spring overflows?" Yang Nan secretly pondered, he didn't destroy this place, in the future, he and even others could continue to cultivate here, there was such a spiritual spring pool was undoubtedly a treasure.

"Huh?" Yang Nan suddenly thought of the downward cave entrance, and the stone ladder, why did that cave appear here for no reason? The entrance of the cave is not far from here, is it possible that someone has absorbed the aura to cause only a puddle of aura spring left?

Yang Nan immediately turned around and rushed towards the stone gap on the rock wall over there, entering the stone gap that was several meters wide, Yang Nan looked up, this could not be a natural formation, it was obviously deliberately excavated.

"Come in and have a look." Yang Nanfei got up and fell straight into the stone steps in the cave, the diameter of this cave is about one and a half meters, and the stone steps are not often there, there is only one about three meters, which is equivalent to a borrowing point, obviously the person who excavated is not to walk with the stone steps, but to borrow strength.

Needless to say, the person who dug this passage must have been a master, otherwise it would not be possible to jump at will to a distance of three meters.

Yang Nan continued to step and jump along the stone steps, all the way up diagonally, and soon he understood what the green light he saw below was, it was a moonstone, this kind of stone can emit a hazy light like moonlight, pale green, used for lighting, and a piece of moonstone will be inlaid every ten meters or so along the cave wall.

Although this kind of stone is not as precious as the Night Pearl, it still has some value, Yang Nan took out the flying sword and cut two pieces into the ring, keeping it for later use.

After walking for hundreds of meters, the cave wall in front suddenly became narrower, with a diameter of only one meter at best, and it became straight up and down, and the stone stairs on both sides also became convex.
