Zhou Aiping is a pure soul cultivator, the progress of her cultivation realm completely depends on the improvement of her spiritual power, and her cultivation method is also based on meditation, when the ideological realm arrives, if the environment aura is abundant enough, the realm improvement is a matter of minutes. As for things like moves and spells, they are not necessities for soul cultivation, all her combat skills come from the comprehension of the mind, and if the Tao ideal is passed, the ability can be achieved, which is a matter of course.

The time between the two and Zhou Aiping was only a few short months, and a few months for soul cultivation may be able to realize many things, but it is more likely that there will be no progress. Like Zhou Aiping, the soul cultivation who has reached the peak of Ning Dan, the slightest comprehension in the spiritual realm is extremely rare, and it is more likely that there will be no progress at all.

The two said goodbye to the medicine king, took the yin and yang tripod out of the divine lake, and took a straight line to the southeast. Their destination, the Shennong Valley, is located in the Daba Mountains in the north of Chongqing, and they plan to cross the eastern part of the Tibetan Plateau, cross the source of the three rivers, and enter the Shennong Valley along the Jianghan Plain between the southern foot of the Qinling Mountains and the Daba Mountains.

Along the way, you need to cross many high and low mountains and valleys on the plateau, as well as the rivers and lakes in the source of the three rivers, after getting off the plateau, you have to climb over the many towering mountains between Sichuan and Shaanxi one after another, for ordinary people, it is basically an impassable road, but for Tian Xu and Ziyan, who have flying skills, there is no easier path than this straight line.

The two of them left the sacred lake and traveled southeast through the winter Hoh Xili wasteland. After flying for a while, Ziyan suddenly said, "Tian Xu, why do I feel as if I am being targeted?"

Tian Xu's olfactory imaging also had a sense of nonexistence, but he didn't find any definite clues, so he didn't say it. At this time, when I heard Ziyan say it, I also paid more attention and switched the olfactory imaging to the background detection mode of inverted colors.

This inverted color detection mode was the one he had just created in the Medicine King Dou, and it was the best at detecting the traces of the absorption of information by the five senses by stealthy cultivators. It's just that compared to the original sinking detection mode, the inverted mode requires more effort. However, he didn't care about the cost, and it was a great way to enhance the practice of this new olfactory imaging modality.

Dan Ling and Tian Xu have a heart-to-heart connection, and when Tian Xu was thinking about detecting the hidden voyeur, Dan Ling also focused on opening the domain detection mode, looking for possible hidden ones.

After a few more minutes, Dan Ling suddenly said to Tian Xu: "Just behind, one kilometer away." "Dan Ling has been studying the spiritual realm for this time, and he is more sensitive to this kind of hidden information than Tian Xu himself.

According to what Dan Ling said, Tian Xu concentrated the olfactory imaging on a kilometer behind, and soon discovered the abnormality. In one place, the visual and auditory signals in the space came out, and the intensity of the outgoing signal fluctuated, apparently absorbed by something. The other party compensated for the absorbed five-sense signal, but this compensation was obviously not serious, resulting in the instability of the outgoing signal. It is not obvious when he is not paying attention, but as soon as he pays attention at this time, it is full of loopholes and clearly appears in his mind.

Tian Xu didn't stop, and transmitted the voice to Ziyan through the domain: "Found it, a kilometer behind us, flying with us." Ignore him and pretend not to find out. I'm just practicing the new olfactory imaging application. ”

Ziyan understood, knowing that this should be a saint realm immortal, she couldn't detect it at all, so she no longer paid attention to the stalker, but just asked with her mind: "Do you know if it's friend or foe?"

Tian Xu said: "I don't know yet, but it can be sure that the earth immortal." The other side does not seem to have malicious intent, at least not for now. ”

The Earth Immortal followed Tian Xu and Ziyan in a stealth state, and it seemed effortless. Among the current Ning Dan Realm cultivators, there are very few who can do this, but for the Earth Immortals, it shouldn't be difficult.

Tian Xu did not change the speed of the flight, but only observed the stalker through passive observation and olfactory imaging. After slowly detecting the range of the abnormal signal of the five senses, he slowly pieced together the appearance of the other party.

This stalker is supposed to be a tall and thin man, wearing a long robe, with long plackets and sleeves, fluttering in the wind, quite a dusty fairy wind and bones. There appears to be a bun on his head, jutting out of the top of his head. It was through the five senses where his clothes and hair were compensated for the abnormality that he found the traces of the other party, but as for the appearance of the other party, he couldn't see it clearly.

In fact, Tian Xu could release Dan Ling out of his body and let Dan Ling stealth on the road he passed by, to get close to the other party, see the details of the other party, and launch an attack if possible. Dan Ling is also composed of aura, and can be invisible like a saint realm immortal.

Tian Xu estimated that the other party must have thought that he had no way to detect his existence, so he would be so careless and let him feel the traces of his existence.

According to the image he felt, as well as the other party's flying posture fluttering in the wind like this, Tian Xu could be sure that he should not have seen the other party, and of course he couldn't judge whether the other party was friend or foe. In this case, he kept his observation of the other party and continued to fly forward.

After walking and following like this, it lasted for more than three hours, and Tian Xu and Ziyan were already approaching the edge of the Sanjiangyuan area. The terrain gradually flattened out, the rivers and plateau lakes became denser and denser, and the aura was much richer than that of the barren Hoh Xili.

The earth fairy who was following them seemed to be tired of following, or had another purpose, and finally stopped following them and turned in another direction. During this period of time, Tian Xu has been continuously running inverted color olfactory imaging, which is much more proficient and easier than at the beginning. And Dan Ling's control of the realm has also improved significantly, and he is already trying to expand the realm even further.

The Sanjiangyuan area is a typical plateau meadow, originally a green meadow in summer, but now it is full of withered yellow, and a small amount of snow is spread on the ground, which does not evenly cover the ground, but is a piece of east and west, revealing mottled withered grassland.

In the spring, he and Ziyan had just known each other, and the two came here for the first time, found a lot of cordyceps together, and also witnessed the shocking process of Xu Jingyi's ascension through the tribulation. At this time, both of them revisited the old place, and both of them could not help but recall the scene at that time.

Ziyan said: "I remember the many cordyceps we found here last time, I wonder if they have grown again now? ”

Tian Xu shook his head and said, "The winter Cordyceps has not grown yet, and it still looks like insects. The aura has not been gathered, so I'm afraid it's not easy to find, and it's not of much use if you find it. ”

Ziyan was unwilling to give up like this, and said, "Maybe there are perennial ground cordyceps, maybe unlike ordinary cordyceps, you can also find them in winter?"

"Okay, let's find out. Tian Xu pretended to be reluctant and said. In fact, his olfactory imaging had already discovered the existence of some Cordyceps, but after he had the Medicine King Dou, he had enough elixir in his hand, and he had insufficient motivation to stop collecting Cordyceps, so he didn't plan to dig it.

Under the thin layer of snow, some Cordyceps that had been frozen by the sudden cold still maintained their growth posture, and the freezing did not affect their medicinal effects, and these Cordyceps could not be hidden in front of Tian Xu's olfactory imaging.

However, Tian Xu didn't want to dig up these ordinary cordyceps, his goal was to go up to the human level or ground level cordyceps, and the ordinary secular level cordyceps really couldn't get into his eyes.

Since Ziyan wants to find Cordyceps, Tian Xu is of course willing to accompany him. With purple smoke, he flew over at an altitude of nearly 100 meters, while olfactory imaging focused on scanning the nearly 400-meter-wide plane below his body, looking for traces of high-order Cordyceps.

Such efficient scanning makes it easy to find Cordyceps. When Tian Xu just started scanning, he found that there were dots of aura dotted on the grassland, he carefully distinguished, and found that these were basically cordyceps, and within a few minutes, Tian Xu found hundreds of plants.

With such an efficient search, soon his target appeared, and a cordyceps plant on the right side caught Tian Xu's attention.

The appearance of this cordyceps plant is not special, that is, a two-centimeter-long grass bud grows at the tail of a worm, but the aura in it is subtle and introverted, but it is thick and rich, and the aura does not simply exist in it, and it is constantly circulating. Cordyceps has a limited volume and cannot meet the needs of Reiki circulation, so the Reiki circulation takes place outside the Cordyceps body.

The aura flowed out from the end of the grass, crossed an arc-shaped trajectory and returned to the head of the zombie insect, and returned to the body of the cordyceps, forming a complete cycle that flowed endlessly. The aura circulating in the circulation was extremely clear in Tian Xu's olfactory imaging, and the shape was like a big apple.

Tian Xu had never seen an elixir that could complete such an aura cycle, he had only felt it in the body of a cultivating animal, and he was sure that this cordyceps was very extraordinary. In his hand, he has the jade bee chrysalis formed by the plateau jade bee chrysalis, which is a heaven-level divine medicine, and there is no such perfect aura circulation process in it.

Appreciating the peculiarities of this Cordyceps, Tian Xu had already swooped down and came to this Cordyceps. He didn't dare to use his aura to remove the snow covering Cordyceps for fear of destroying the fragile structure of Cordyceps. But he had a safer solution.

In a flash of thought, Dan Ling in the sea of consciousness had already made a move, using the control ability of the domain space to easily remove the snow and withered grass covering the Cordyceps, and completely exposed the Cordyceps in front of him and Ziyan.

At this time, he was close, and he could already be sure that this Cordyceps should be a high-grade grass-roots plant, and the grade was not as high as he expected, but there was one thing that was different from other ground-level immortal medicines, that is, this Cordyceps had extremely strong vitality. In the realm, Tian Xu's senses were extremely sensitive, and he could even feel that with the circulation of the aura, the aura in this cordyceps was still slowly increasing, and its growth was far from reaching its limit!
