To be honest, the combat effectiveness of these people in the Three Immortal Views was really more than one grade lower than their realm, which made Tian Xu a little puzzled.

It is said that in a sect, there are more than ten or nearly twenty Ning Dan Realm cultivators, and at least two masters who have reached or approached the peak of Ning Dan, and the overall combat effectiveness should not be so bad.

Later, he thought about it and guessed a rough idea. Since these three immortal temples are famous for their expertise in alchemy, the pills they sell to the outside world are mostly common medium and low grades, which is completely different from the situation where Shennongmen and Xiduotang, which are also famous for their alchemy, have high-grade pills for sale from time to time, and their main customer groups are scattered cultivators and small and medium-sized sects. Most people in the cultivation world thought that the alchemy strength of the Three Immortal Views was worse than that of Shennongmen and Xiduotang, and they were also very low-key, and they had little contact with the various sects in the cultivation world.

It is estimated that a large number of their high-quality pill resources are left in the sect for their own use, and they have so many condensing pill realms, it is estimated that most of them are born from pills, although the realm has arrived, but they lack the perception and background of their own cultivation, and their combat effectiveness will certainly not be too high.

At this time, the three immortal spectators who besieged the valley mouth of Shennong Valley quickly retreated, and Tian Xu had no intention of pursuing, and turned back to see the guardian formation of the valley.

From the outside, this valley mouth is an ordinary stone wall, slightly concave inward, and judging from the attack of the Three Immortal Views just seen, the guardian formation seems to be a simple defensive formation, and there is no counterattack to the attack from the outside world. And this kind of formation is also the best formation used for concealment, which is less easy to detect and less difficult to break than the formation that can counterattack.

Tian Xu didn't have to forcibly attack like the Three Immortals, Zhou Aiping told him the way to call the door. But when he imitated the position pointed out by Zhou Aiping and went to find the communication formation, he found a tragedy. Under the indiscriminate attack of the three immortals, the communication formation composed of two stones protruding from the rock wall and two pits, only one pit remained, the other three had been destroyed, and the two raised stones did not even leave a trace.

Tian Xu had no choice but to go back and test Taniguchi's guardian formation. He did some research on the formation himself and wanted to see if there was any way to get in.

But when he unfolded his aura and tested the guardian formation, he found that this formation was far from something that a half-witted person like him who played the formation could figure out. The array's weapon is inside the valley, and the outside world only shows the range of action of the formation. This goalkeeping formation cannot touch the formation from the outside, and there is almost no solution, so you can only attack it by force, or find a way to bypass it.

Tian Xu tried his best to imagine the possible situation in Shennong Valley, but no one had told him at all, and of course he couldn't think of it. However, he thought of the Warcraft space in the Tianshan Mountains, as well as his Medicine King Dou space, combined with the analysis of the geographical environment here, guessed that this Shennong Valley was probably also a folding space, with his current strength, even if he knew the direction of the space, the possibility of breaking through the space barrier to enter was quite small. It seems that you still have to break through the guardian formation to enter, or find a way to notify the people in the valley to let you in.

He sat in front of Taniguchi and thought for a while, and finally came up with a possible solution: "Since the communication formation has been destroyed, then the only possible energy exchange between the outside world and the valley is this guardian formation. Can I use the Attack Guardian Formation to send some signals in?"

He tried to attack the Guardian Formation from different angles and forces, and the formation would bounce his attacks back one by one. However, while rebounding back, some of the energy was still absorbed by the formation. After turning on the inverted mode of olfactory imaging, the absorbed energy was suddenly clearly displayed in front of him. Sure enough, as he expected, there were several angles that absorbed significantly more energy than other places, and even if he didn't attack, these places were constantly absorbing the information of the five senses of the outside world, obviously this was Shennong Valley's external observation port, but I don't know if someone was paying attention to the situation in the outside world. However, according to his guess, if there were people inside, they would not fail to pay attention to the outside world when they were attacked by the outside world.

Now that he has driven the people of the Three Immortal Temples away for half an hour, there is still no reaction in Shennong Valley, so either there is no one inside, or something has happened, so that the people inside have no time to look outside. Tian Xu couldn't help but worry more about Zhou Aiping.

He continued to study the several observation points at the entrance, trying to transmit signals in various ways, but to no avail. Later, he had an idea and remembered something: "I don't know if the original communication formation is related to these observation points? Can you try to repair the internal communication formation?"

As soon as he said and did, he first came to the only well-preserved pit among the four communication formations, and explored the way to absorb signals from the outside here.

Zhou Aiping told him that the communication method was to input spiritual energy into the four communication formations and transmit sound signals into them. He tried to transmit the sound signal, and found that after the signal was absorbed, it was finally transmitted by the formation to an observation point in the guardian formation. He tried to input the aura with sound signals into the damaged pit, and found that the pit could still transmit the signal to an observation point, but the signal transmitted was a little chaotic, and it was estimated that it was no longer possible to identify.

Tian Xu probably understood the principle of this communication formation, and he estimated that this communication formation should have been added later, and it was far from the level of the guardian formation, so that he didn't even deform when transmitting the signal, but just amplified the signal slightly and passed it in.

He carefully counted the number of observation points in the guardian formation, and found that there were four of them, which corresponded to the communication formation, and immediately transmitted his information directly from these four observation points.

He thought that he would have to wait for a while to give it some reaction time, but the result was much happier than he imagined, and as soon as his signal was sent in, Zhou Aiping's voice came from the formation: "It's Tian Xu who is here, just come in directly." ”

Tian Xu saw that the appearance of the guardian formation had not changed, and asked, "Aunt Zhou, can Ziyan go in with me?"

As a result, Zhou Aiping's voice sounded again: "It's Tian Xu who is here, just come in directly." It turned out that this voice was not answered by Zhou Aiping inside, but a reaction signal set in advance, which was played like a recording.

Tian Xu couldn't get feedback from Guzhong, and he didn't know if Ziyan would be in danger if he passed the guardian formation with him, so he was a little hesitant in his heart. But Ziyan couldn't wait, and had already taken his hand and stepped into the formation. Tian Xu didn't pay attention for a while, he was pulled by the purple smoke, and saw that the purple smoke had entered the mountain wall, so he hurriedly followed.

In fact, he was too cautious, and when they passed, the guardian formation was like an ordinary hidden formation, and there was no reaction at all.

After stepping over the guardian formation, the eyes of the two suddenly widened, and they were already in a small valley, surrounded by nine mountain peaks. The valley is very small, only about twenty or thirty meters wide, and more than half a mile long. The valley was not straight, but winding, with peaks on both sides staggered like dogs' teeth, each of which was not tall, and the largest one was behind them, blocking the entrance to the valley like a portal. The highest mountain is less than 100 meters high.

The aura in the valley was extremely abundant, even more intense than that in the Medicine King Dou, so that both Tian Xu and Ziyan couldn't help but take a deep breath. But the strange thing is that although the spiritual energy in this valley is abundant, there are no plants growing at all, and it is bare everywhere.

Tian Xu raised his voice and said, "Is Aunt Zhou here? I'm Tian Xu!"

The valley is not big, and the sound doesn't seem to be able to come out, and it reverberates back and forth in the valley, and the echo is endless for a long time. He waited for a while, but didn't hear Zhou Aiping's response, so he couldn't help but feel anxious, and walked towards the valley with Ziyan.

Tian Xu and Ziyan saw that no one answered in this valley, and at the same time, they flew up in the air and suddenly circled the valley. The valley was only more than 200 meters long, and it only took Tian Xu and Ziyan a few seconds to turn around, and they didn't find any places that could hide, and they were bare everywhere, as if no one had ever come. There must be something wrong with this, maybe this is not Shennong Valley at all, or maybe it's just a transit point to Shennong Valley.

However, although he didn't find anyone, Tian Xu discovered another thing: the nine peaks here all have excellent accommodating aura, how good is it? At least it won't be worse than the spirit rhino finger he used to refine the spirit soldier!

Tian Xu stretched out his hand and touched a mountain peak next to him, and found that the mountain stones on this peak were not hard, they were slightly soft, these mountain stones seemed to be all spiritual rhino fingers, and the grade was better than his spiritual rhino fingers of a few Tibetan antelope horns!

"Get rich!" Tian Xu's heart was suddenly filled with excitement, and happiness came too suddenly, which caught him off guard. With so many Spirit Fingers, it was enough for him to refine a large number of formations, weapons, and talismans. When fighting with people, a large handful of talismans and formations are thrown at the opponent like no money, who dares to flee without crying and shouting for his mother?

Just when Tian Xu was happily carried away, Yin Yang Ding, who had been hiding in his body, suddenly spoke: "Tian Xu pay attention to it, I seem to feel the breath of the hundred grass whip near here, but this breath is very light, and I can't feel his position for a while." You look around and see if you can find him. ”

"Hundred grass whips, what does he look like, what are his characteristics?" Tian Xu asked, "I don't have a clue here, how to find it?"

Yin Yang Ding thought for a while and said, "It is said that the Hundred Grass Whip should be a big gray-brown whip, with a restrained aura, and nothing too special. However, I heard Shennong hoe say that he has been seriously injured, and it is difficult to say what has become of him now. Judging by his breath, this guy is already dying, even if he is smashed to pieces. However, this guy was refined by the Great Emperor with the backbone of a ninth-level demonic beast spirit dragon, and the material is similar to the spirit rhino finger in your hand, so it should be easier to distinguish. ”

"Ah," hearing Yin Yang Ding say this, Tian Xu couldn't help but shout, "The Shennong Valley where I am now is surrounded by a hill composed of nine spirit rhino fingers, could it be that this Shennong Valley is a hundred grass whips?"
