The resentful spirit that was just swallowed by Ding Mu came from a sect called Yinsha Sect during his lifetime. This sect mainly focuses on cultivating killers, and mainly practices killing intent and hidden magical powers, which are more than 90% similar to Wukong.

More than 5,000 years ago, Zhong Yan led Qianlong Gate to destroy all the sects on the Butterfly Star, and Yinshamen was no exception, so the inheritance of Yinshamen was cut off. However, Ding Mu speculated that there should be some records about Yinshamen in the warehouse of Qianlong Gate, and even the magical powers of Yinshamen.

Of course, Ding Mu's goal is not the magical powers of the Yinsha Sect, but to find a more powerful resentful spirit from the Yinsha Sect, so that Wusha will swallow the resentful spirit, which may have unexpected effects.

So Ding Mu did not stop at all and continued to go deep into the Necrotic Valley, always maintaining the state of excitation in the Thunder Sword Realm, wanting to find those vengeful spirits who are good at hiding and assassinating.

But things in the world are often not as good as you wish. When you want to find something, you can't find it. When you are about to give up, they may pop up directly, so Ding Mu spent three days without any gains.

However, Lin Shihui finished her practice and came out of her portable space.

Ding Mu could sense that Lin Shihui's breath fluctuations increased significantly, but he did not mean to break through to the third level of the Wendao Realm. This result surprised Ding Mu a little.

The spiritual energy contained in the body of the resentful spirit in the dusk drum realm is far greater than that of Lin Shihui's breakthrough, so why is there no breakthrough?

Lin Shihui saw Ding Mu's doubts and explained: "The body of the resentful spirit contains spiritual energy. I need to use the demonic energy to assimilate the spiritual energy and absorb it. The efficiency needs to be reduced, and there will be a lot of losses. Therefore, the demonic energy that can really absorb is only two layers at most."

"And don't forget that every time I break through, the demonic energy I need is extremely huge, better than other Qi Refiners. This is what we discovered in the low-dimensional world, but we don't know what's going on, so I still don't have the moment to break through."

Ding Mu nodded, understood Lin Shihui's situation, and said, "It doesn't matter. I can sense your obvious progress. If a resentful spirit doesn't work, then come a few more. You need a lot of demonic energy to improve it, which is also a good thing. At least your foundation will be far better than others. When you break through, the bottle barrier you encounter will be easier to break."

Lin Shihui nodded, "I know, so I'm really not in a hurry at all. Compared with other Qi Refiners, my cultivation speed can already shake them ten streets away. Why should I be in a hurry?"

He said this, but Lin Shihui was still very anxious because he never compared to ordinary Qi Refiners. All she had to do was to try to catch up with Ding Mu's footsteps, rather than being thrown away by Ding Mu.

Afterwards, Ding Mu specially captured a resentful spirit in the dusk drum realm, let Lin Shihui swallow it, and then returned to his portable space to continue practicing.

Lin Shihui's affairs had just been dealt with, and Wusha had also come out. His cultivation level had been upgraded to the second level of the Wendao Realm, and it was not far from the third level.

This is the normal situation. After all, during the process of devouring and transformation, a large amount of spiritual energy will always dissipate. Ding Mu was surprised that such an effect had already been achieved.

Wusha didn't speak, and continued to hide his body and stayed with Ding Mu.

As Ding Mu's cultivation and combat power continued to improve, Wusha knew that the gap between him and Ding Mu had been infinitely widened. Apart from staying with Ding Mu as a shadow, he didn't know what else he could do.

Ding Mu saw Wusha's actions and said, "I have discovered a kind of resentful spirit here, who is good at concealing and assassinating. They come from a sect called Yinsha Sect, who mainly practices murderous intent and concealing magical powers. They are the same as you. If you can encounter such resentful spirits, after devouring them, your cultivation and combat power should be significantly improved."

Wusha nodded and asked, "If you ask me to improve my cultivation and combat power, aren't you afraid that I will really kill you one day in the future?"

Ding Mu smiled, "Actually, I still like the way you have been chasing me and want to duel with me, because that will make me feel the pressure, not in this state now. Although I have been practicing very hard, I still hope that a knife will hang above my head. If I dare to relax, the knife will fall. Do you understand what I mean?"

Wusha snorted coldly, "Do you treat me as a tool for you to improve your cultivation?"

Ding Mu said, "Whatever you think? Let's go, I've been looking for it for three days and haven't met a suitable resentful spirit. Next, it depends on whether you have such good luck."

After that, Ding Mu took Wusha to continue to go deep into the Dead Valley. A day later, the two of them did not find a suitable resentful spirit, but they sensed a large number of resentful spirits' aura fluctuations.

Wusha was very sensitive to aura fluctuations, so he immediately concealed his body and sent a voice to Ding Mu: "There are a large number of resentful spirits in front of him, and their cultivation is not weaker than the one we encountered for the first time. You must be careful!"

Ding Mu nodded, and he also sensed the fluctuations of the aura of the resentful spirits, with the number of them being no less than one thousand, including nearly one hundred resentful spirits in the realm of the morning bell!

After sensing these, Ding Mu was also a little surprised. Why were so many resentful spirits gathered together?

Could it be that the vengeful spirits in the Necrotic Valley have formed a distinct organization?

The more Ding Mu thought about it, the more he felt that this was possible.

The Dead Spirit Valley was formed because the Qianlong Gate destroyed all the sects on the Butterfly Transformation Star and buried the corpses of countless powerful people in these sects here.

Although the resentful spirit is different from the human Qi refiners, it has a high degree of wisdom. After more than 5,000 years of development, it is very likely that Ding Mu did not discover this before, but because he did not go deep into the Necrotic Valley, he did not encounter it.

Now that he sensed the gathering of thousands of resentful spirits, Ding Mu was more or less curious, carefully concealed his breath fluctuations, sneaked up, and wanted to see what these more than a thousand resentful spirits gathered together.

He dared not be arrogant without killing, so he honestly entered Ding Mu's portable space and observed the changes outside through the portable space.

After Ding Mu approached, he could clearly sense the aura fluctuations and divisions of these thousand resentful spirits. They formed a circle in this open space. A resentful spirit whose cultivation fluctuates to reach the fifth level of the Morning Bell Realm stood in the middle, constantly making strange sounds. Moreover, because of the many changes in this sound, it is likely that it is the language between resentful spirits.

Ding Mu did not understand these languages, so he naturally did not know what the other party was saying. But what is certain is that the vengeful spirits in the Necrotic Valley have indeed formed a clear social order, and to a certain extent, they followed the principle of the strong prey on the weak. Resentful spirits with high cultivation and strong standing have greater voice, such as the vengeful spirit surrounded by many vengeful spirits.
