Chen Nan held a low-grade spirit stone in his hand, and the small sapling exuded a quiet aura, allowing him to quickly get rid of distracting thoughts and settle down, the spiritual energy in the spirit stone was absorbed and refined by the meridians, and a spirit stone quickly turned into ashes, but his cultivation increased but not obviously. Chen Nan knew that the resources he needed now were far greater than before, so he simply held a medium-grade spirit stone in his hand and continued to refine.

In Jiugong Mountain and the Famous Sword Sect, he got two middle-grade spirit stones and nearly sixty lower-grade spirit stones, but his own women also had to cultivate, and they had to leave resources for them, and the duck eggs were also rationed with spirit stones, and he only had two middle-grade spirit stones and more than a dozen lower-grade spirit stones on him.

Although the value of one medium-grade spirit stone and ten lower-grade spirit stones are equivalent, but the middle-grade spirit stone is much stronger than the lower-grade spirit stone in terms of spiritual energy content and purity, and the abundant spiritual energy enters the meridians and returns to the sea of qi, and the vast true qi gushes out from the sea of qi to broaden his meridians, and his cultivation rises significantly, and he quickly comes to the peak of the middle stage of the fifth layer.

Chen Nan quickly swallowed two Qi Building Pills that broke through the small level, and the Qi Building Pill quickly turned into bubbling spiritual power, fusing with the spiritual energy in the spirit stone, and the true qi became even more agitated Peng Bai, and I don't know how long it took, a medium-grade spirit stone turned into flying ash, and under the impact of the two Qi Building Pills and the pure spiritual energy equivalent to more than a dozen lower-grade spirit stones, he successfully entered the late stage of the fifth layer of Qi Condensation.

Fortunately, the little sapling helps to settle down, get rid of the demons in the cultivation, can make him feel peaceful, and it is of great benefit to the realm of enlightenment, and the full true qi is still stirring in the meridians, Chen Nan did not hesitate, once again held a medium-grade spirit stone in his hand, and soon entered the realm of selflessness.

As the aura was gradually refined and absorbed, the true qi in the sea of qi became more and more condensed, and every time it was channeled out, it was surging and agitated, washing the meridians over and over again, and I don't know how long it took, he finally touched that barrier. Chennan, who was in the realm of selflessness, used his true qi even faster, trying to break through that barrier, but he failed several times.

"Click!" The spirit stone in his hand turned into flying ash, Chen Nan woke up from his meditation, looked at the spirit stone that turned into fly ash and smiled bitterly, the two medium-grade spirit stones, such a pure spiritual energy could not help him break through to the sixth layer of condensation.

He had already touched that barrier, he didn't want to give up halfway, he held the two lower-grade spirit stones in his hand again, absorbed the spiritual energy, and guided the thick true qi in the sea of qi to wash the meridians, and finally touched the barrier again, that barrier seemed to be able to be pierced at any time, but it was always in front.

The spirit stone in his hand turned into ashes again, and his cultivation was stable at the peak of the fifth layer of condensation, but the sixth layer of condensation still had not been broken through, although it was only a matter of realm, but the strength contained in it was not the same.

Chen Nan knew that even if he consumed the remaining lower-grade spirit stones, he might not be able to advance to the sixth layer of condensation, so he sighed helplessly, how precious the spirit stones were, he didn't want to waste them anymore, he sat quietly for a while, and recalled the cultivation bottleneck mentioned in the red jade, according to the records in the red jade, if you want to break through the realm, it is not entirely dependent on resources, the assistance of the elixir spirit grass, and the tamping of the state of mind is also essential.

He could feel that the accumulation of his true yuan was enough, and it would take a chance to break through, he couldn't help but think of the sinkhole on Mount Everest, and thought of Zhen Zilan, if he wanted to break through the sixth layer of condensation, he needed a Xiao Yuan Dan, and if he wanted to refine Xiao Yuan Dan, there was only Zhen Zilan at present.

Chennan's consciousness swept out, it had already been a night, the sun was shining outside, the snow on the top of the mountain was particularly shining and dazzling under the sun, Chennan walked out of the Qinglian world, stood on the top of the mountain, and looked at the direction of Mount Everest.

"The path of cultivation is to fight for one's life with the sky, how can I succeed if I am afraid? If I die, it is also fate!" Chen Nan's eyes became more and more determined, and he made up his mind that no matter how dangerous the sinkhole was, he would take another trip, pick up Zhen Zilan, and refine it into Xiao Yuan Dan, not only for himself, but also for others to find a truly feasible path of cultivation.

"Brush!" The Xuan Ice Spear crossed the air, Chen Nan rose up again, a black light crossed the sky, and went straight to Mount Everest, although he only advanced to a small level, he obviously felt that the flying of the imperial spear was more handy, that is, he flew back to Huhai directly, and it was enough to rest only once in the middle.

Two hours later, Chennan landed on Mount Everest, which is close to the summit of Mount Everest, cliffs can be seen everywhere, surrounded by a silvery world, frozen for thousands of miles, covered with snow, blizzard hurricanes swept the mountains, ice chips flew, in this extreme cold, there is no life.

Chen Nan looked at the sinkhole from afar, and did not rush to enter, the continuous flight of two hours consumed a lot, he first entered the Qinglian world to resume his cultivation.

After Xiu Wei completely recovered, Chen Nan stabilized Xiu in the best state, and without hesitation, he rushed to the direction of the valley, landed outside the sinkhole, and looked down.

The sinkhole is full of spring, the blood of those who died last time has disappeared, the ice coffin in the middle of the sinkhole is up and down, the old man is still as thin as firewood, white hair as grass, as if dead, the red vitality on his face due to the absorption of blood has long disappeared, everything is the same as when he first came here, but the ancient martial arts masters outside the sinkhole are missing.

Chen Nan believed that the old monster in the ice coffin was definitely not dead, according to his understanding of Xiuzhen in the past few years, especially after seeing the old man who was about to live in the Valley of Despair, Chen Nan guessed that this person was also promoted or had no hope of becoming an immortal, and Shou Yuan was approaching, so he sealed himself with the ice coffin to avoid the loss of vitality.

There have been reports in the world of people hundreds of years ago who were sealed in the ice and snow of extremely cold places to survive, and it is also a good way for cultivators to seal themselves with ice cubes to keep alive and continue their longevity.

Chen Nan estimates that even if the old man is disturbed, he will not easily break the seal, because this person himself has not much life, once the seal is broken, his life may come to an end, and he will not break the seal unless he has to, which is also one of the guarantees for his dare to go down, that is, to bet that the old man will not break the seal.

Chen Nan took a few steps forward, standing on the edge of the sinkhole, his divine sense swept to the bottom of the sinkhole, the Zhenzi orchid was still there, but the surrounding bones were all over the place, presumably there were still people who came here to investigate, trying to pick the spirit grass, and many people were buried in the sinkhole.

"To go down or not to go down?" Although it is guessed that the old man will not break the seal, but the strange bell is still terrifying, although Chen Nan Xiuwei is the peak of the fifth layer of condensation, but because the sea of qi is more condensed, his strength has also increased several times compared to before, I don't know if he can resist a bell?

It is enough to resist once, and as for resisting twice, you don't have to think about it, once you don't rush out of the sinkhole before the second bell rings, you will definitely turn into dry bones like everyone else.

"You have to give it a try if you can do it or not, it's a big deal to die, you can't achieve the immortal path, what's the use of living for a few more decades?" Chen Nan muttered to himself, looking at the ice coffin with more and more resolute eyes.
