After half a burnt incense, a refreshing medicinal fragrance overflowed in the control room, making Xie Nanping couldn't help but open his eyes again, and at this time, Qiao Yun was controlling his divine sense to pull out twelve white pills from the Dan furnace.

This is...... Pei Zhen Dan! Xie Nanping's eyes widened suddenly, if he wasn't still cultivating, he would even want to take these twelve pills in his hand and take a closer look.

Although Xie Nanping couldn't refine the fourth-grade Peizhen Dan of the Spirit Rank, as a Dan Master, he still had eyesight, and after just sweeping it, he was shocked to find that only two of the twelve white Peizhen Pills were top-grade pills, while the remaining ten were all top-grade pills.

At this moment, the shock in Xie Nanping's heart was beyond measure, Qiao Yun had not only refined the fourth-grade Peizhen Pill of the Spirit Rank in just half a pillar of incense, but the quality of the twelve pills was even higher, what a superb level of alchemy it would take to achieve such attainments!

Don't...... Could it be that Senior Brother Qiao is already a fifth-grade or even higher-level alchemist? Xie Nanping didn't dare to continue thinking about it, but soon he thought of the self-confidence he had when he told Qiao Yun earlier that he was a Dan Master, and his face suddenly turned blue and red.

Qiao Yun didn't know that Xie Nanping had turned so many thoughts in his heart, the reason why Qiao Yun refined the Peizhen Pill was to help Xie Nanping improve his strength, so that he could reach the cultivation of the middle stage of the eighth layer of foundation building as soon as possible, so that he could go with him to rescue Ren Xiang.

As for the materials of this Peizhen Pill, there were many of them in the large amount of spirit grass collected by Qiao Yun before and the spirit grass scavenged from other monks' storage bags, and the ability to refine such a high-quality Peizhen Pill was related to Qiao Yun's refining of Peizhen Dan many times, but it was also inseparable from Qiao Yun's use of the Eternal Night Fire.

Because of the use of the Eternal Night Fire, Qiao Yun does not need to consume the true qi in his body at all, so he also saves the cumbersome task of controlling the size of the condensed true fire by controlling the speed of the true qi circulating in the body.

After putting the pill into the jade bottle prepared in advance, Qiao Yun directly took out two top-grade Peizhen pills, and threw the pill into his mouth when he made Xie Nanping open his mouth.

After the elixir was entered, it instantly turned into a bubbling liquid and flowed into Xie Nanping's abdomen, Xie Nanping only felt that a violent spiritual power was instantly wanton in his body, he didn't dare to delay, and the mental mantra was running even faster, while transforming the majestic spiritual power in his body, he still continued to absorb the spiritual energy overflowing from the spirit stones from the outside world.

Half a day later, Xie Nanping successfully advanced to the middle stage of the seventh layer of foundation building, and his face showed joy......

A day later, the twelve Peizhen Pills were all consumed by Xie Nanping, so Qiao Yun opened the furnace for alchemy again, and this time he refined five furnaces of Peizhen Dan in one go for Xie Nanping......

Three days later, Xie Nanping successfully advanced to the late stage of the seventh layer of foundation building......

Seven days later, Xie Nanping broke through to the early stage of the eighth layer of foundation building, and the momentum on his body instantly increased sharply, more than a star and a half stronger than when he built the seventh layer of the foundation......

And after reaching the early stage of the eighth layer of foundation building, the effectiveness of Peizhen Dan gradually decreased, and Xie Nanping's cultivation speed also began to slow down, and it was not until fifteen days later that Xie Nanping finally blasted through the barrier in his body and successfully advanced to the middle stage of the eighth layer of foundation building.

When he successfully broke through, Xie Nanping's eyes couldn't help but show a fierce joy, he couldn't have imagined that in just half a month, he had soared from the early stage of the seventh layer of foundation building all the way to the middle of the eighth layer of foundation building, and this kind of rapid improvement of cultivation was really cool, making him feel hearty and unfinished.

It took another whole day for Xie Nanping to completely stabilize his cultivation, and then he slowly opened his eyes, and what came into his eyes was the powder made of spirit stones, and the jade bottles that had long been empty.

"Thank you, Senior Brother Qiao!" Xie Nanping solemnly looked at Qiao Yun and said, he knew in his heart that it might take several years, or even more than ten years, for many monks to be promoted from the early stage of the seventh layer of foundation building to the middle stage of the eighth layer of foundation building, and under the accumulation of this large amount of resources, he had already surpassed half a month in half a month, which was undoubtedly a great kindness!

Qiao Yun was also very happy when he saw that Xie Nanping had been promoted to the cultivation of the middle stage of the eighth layer of foundation building, and patted Xie Nanping on the shoulder, "Brother Xie, don't say thank you, let's discuss the plan to rescue Ren Xiang as soon as possible!"

Xie Nanping naturally knew that Qiao Yun was anxious for Ren Xiang's comfort, and hurriedly nodded, "Everything is at the command of Senior Brother Qiao!"

Raised his hand to remove the three illusions on his face, and then Qiao Yun handed the three illusions to Xie Nanping and let him wear them on his face.

Soon, when Xie Nanping took the Three Illusions, he instantly turned into the appearance of a scholar, but at the top of his head, there was a faint crack that extended to the bridge of his nose.

"Brother Xie, you control your mind and change your appearance. ”

Under Qiao Yun's guidance, Xie Nanping's face changed instantly, and in a blink of an eye, he became a big man with a beard.

Looking at Xie Nanping, who was carrying the Three Illusions in front of him, Qiao Yun asked him to stand up, walked around him carefully, and then nodded slightly.

Xie Nanping and Qiao Yun are of similar height, but their body size is more rugged than Qiao Yun, but after transforming into this big man with a beard, it reflects his original body shape, and he can't see much difference from Qiao Yun after he transforms without paying careful attention, plus the robe of the Qingyu Sect is looser, so Qiao Yun is ninety percent sure that Xie Nanping will not be immediately recognized by Shao Feiyu.

As for Shao Feiyu knowing that he was not dead, Qiao Yun had two guesses, one of which was likely to be when he was robbing the eternal night fire, he saved Ren Xiang and was seen by Shao Feiyu, so he guessed that it was himself, and the second possibility was that Shao Feiyu later returned to the valley and found that the formation left behind had been broken, so he realized that he might still be alive, so he caught Ren Xiang, who had a low cultivation level and had no foundation in the Qingyu Sect, and wanted to lure himself out.

However, no matter what the situation is, Qiao Yun knows that if he transforms into a big man with cheeks, Shao Feiyu will definitely know that it is him, because he has shown him the auxiliary magic weapon of the three illusions.

"Senior Brother Qiao, do you want me to go for you?" Xie Nanping saw Qiao Yun stop and spoke, obviously he also vaguely guessed Qiao Yun's purpose.

"Not for me, but for you. Qiao Yun shook his head slightly, "When the time comes, I will hide and wait for the opportunity to move, while you will stabilize him first and delay as much time as possible so that I can find Ren Xiang's whereabouts." But you have to be careful of the formation he arranged, this person is very good at using formations, last time I strayed into the formation and was injured by him. ”

Xie Nanping didn't expect Qiao Yun to go with him, so he couldn't help but be stunned for a moment, not understanding the difference between this and what he said before to hide and follow Qiao Yun.

But the next moment, Xie Nanping was in his heart, because he found that he couldn't feel the slightest breath of Qiao Yun in this control room, but Qiao Yun was obviously standing in front of him.

"Good exercises!" Xie Nanping sighed, and at the same time finally understood why Qiao Yun didn't agree with his suggestion before, compared to Qiao Yun's concealment technique, his own concealment was simply not worth mentioning.

After recovering the breath on his body, Qiao Yun took out a lot of defensive magic weapons and attack magic weapons from the storage bag and handed them to Xie Nanping, and Xie Nanping knew that this trip was dangerous, so he did not refuse, thinking that after successfully saving Ren Xiang, he would return these magic weapons to Qiao Yun intact.

Then Qiao Yun and the others thought about a lot of possibilities after meeting Shao Feiyu, and discussed some strategies to deal with it, and then they controlled the flying magic weapon to slowly rise from the woods and returned to the rolling river again.

Xie Nanping sat cross-legged in the control room, constantly controlling the flying magic weapon to fly along the river to the downstream of the big river, while Qiao Yun had already restrained the breath of his whole body and hid it in the corner of the control room, and even the color of his body and clothes had been integrated with the flying magic weapon behind him.

With the continuous flight, the river surface is getting wider and wider, and finally the distance between the two sides of the river is even more than a thousand zhang, a large amount of yellow sand continues to integrate into the river water, but because the river surface is open, the river water on both sides is extremely turbid, and the river water in the middle is relatively clear, forming such a peculiar scene.

An hour later, Xie Nanping controlled the flying magic weapon to the end of the big river, and here, a huge waterfall was formed, the drop was a hundred zhang high, and the rolling river water poured down from this place, smashing into the huge lake below, stirring up endless water mist, making the entire waterfall under a haze.

After Xie Nanping saw this scene, he knew that he had come to the agreed place between Shao Feiyu and Qiao Yun, so after his eyes flashed slightly, he controlled the flying magic weapon and began to descend slowly.

Five, ten, thirty meters...... When it descended to a hundred meters, the flying magic weapon hovered steadily, Xie Nanping looked at the huge waterfall faintly in the mist in front of him, took a deep breath, and then moved without hesitation, and the flying magic weapon instantly rushed towards the direction of the waterfall.

The majestic river water continued to smash on the flying magic weapon, making a "whoosh" sound, and the entire flying magic weapon sank slightly downward under this huge impact, but soon, the flying magic weapon rushed through the thick waterfall water curtain and came to the waterfall.

I saw that this place turned out to be quite an open place, with huge rocks above and below, which should be a huge cave formed naturally. And in the depths of this place, two green-shirted monks were sitting cross-legged there, and when they saw a flying magic weapon coming, both of them opened their eyes one after another.
