Just a moment ago, I was still fine, so why did I suddenly turn hostile? I asked in confusion, "What? What I said was wrong. I made you so angry?"

He waved his hand and said, "The responsibility is not yours, but the Yin Qi and the Demonic Qi in your body. This is what the Demon King wants the most, if it were to take it, the whole world would no longer have peace."

"Junior also thought of this result. I originally wanted to leave Thunderclap Mountain, but …" I turned my head to look at Qing Qing and continued, "I must find the Tranquil Heart Grass to help Qing Qing remove the demonic nature in her heart."

"Did the Demon King not tell you the whereabouts of the Tranquil Heart Grass?"

I shook my head.

The black clothed man touched his sleeves and said, "Tranquil Heart Grass was grown on Thunderclap Mountain five years ago. At that time, I also discovered its existence, but I did not pick it. Who would have thought that the next time I go, I would find that the Tranquil Heart Grass has disappeared, leaving behind only a few pieces of the red-eyed bat's feathers. "

"Ah, so you're saying that the Tranquil Heart Grass is in the hands of the Monster King?"

"That's right, last year when we fought the Monster King, it was proudly talking about the Tranquil Heart Grass. It is currently using the Tranquil Heart Grass to enhance and strengthen its Yin Qi, and it is also very sad. It will be even harder for me to deal with the Monster King."

After finally hearing the whereabouts of the Tranquil Heart Grass, I anxiously asked, "Uncle Black Cloak, do you know where the Monster King hid the Tranquil Heart Grass?"

"Hide?" The black-clothed man waved his hand and said, "The Monster King can directly swallow it into its body. Only in this way will the Tranquil Heart Grass be of the greatest use."

When I heard that the Monster King had swallowed me, I was immediately dumbfounded, "It's over, there's completely no hope for this."

"You can't put it that way either. Although the Tranquil Heart Grass was swallowed by the Monster King, it did not sustain any injuries. The Demon King just swallowed it and used the Tranquil Heart Grass to help it strengthen its Yin Qi. "

These words sounded contradictory. According to the understanding of ordinary people, whatever was swallowed into the stomach would be quickly digested. Since that was the case, how could Tranquil Heart Grass be alright?

Soon, he got the answer from the mouth of the man in black. It turned out that the Tranquil Heart Grass wasn't used for its own body but for its smell. This smell was the main factor in the Tranquil Heart Grass's effectiveness.

I thought for a while before understanding the contradictions between the two. Scratching my head, I said, "If I can once again take out the Tranquil Heart Grass from the Monster King's stomach, would the Tranquil Heart Grass still have any use?"

"I've already said this before, the Tranquil Heart Grass won't be damaged. It's just that, there's a prerequisite here. First, we have to defeat the Monster King. Do you have any way to defeat the Monster King?"

I didn't have any plans, so I shook my head and cupped my fists towards Uncle Black. I approached him and said, "Junior is very naive and knows that I have no way of defeating the Monster King. I still hope to receive senior's help."

The black clothed man was quite satisfied with my attitude and nodded. "Very good. That's exactly the attitude you need. As long as you all listen to my arrangements, I have a way to deal with the Monster King."

"Oh, please inform me, senior."

"Don't call me senior, I still like the name 'Uncle Black Cloak'." After smiling at me, he continued, "According to what you said, the reason why the Monster King is strong is because it devoured a lot of its soul and also gave it a lot of life. Even if we kill it for a few days and nights, it might not necessarily be able to harm its original body.

I curiously asked, "What formation is it?"

"Heavenly Dipper and Earth Fiend Demon Subduing Array!"

After the black-clothed man's explanation, although this Demon Subduing Formation looked simple, there was a huge requirement for it to truly display the power of the formation. Firstly, the activation conditions of the Demon Subduing Array required a balance between Yin and Yang. This alone was extremely difficult to accomplish.

The Yin and Yang within the Demon Subduing Formation were not the Yin and Yang that Daoists often said, but the true Yin and Yang.

This required at least two people to activate the array. One of the attributes had to be Yang and the other Yin. Only when Yin and Yang were both inside the array could the Demon Subduing Array be activated.

This was also the only way Uncle Black could think of to deal with the Monster King after seeing Qing Qing and I.

From a glance, he was clearly a cultivator. His entire body was filled with the Supreme Yang Qi, which was the Qi produced by his cultivation of Dao arts.

Of course, I am a human after all, and not a true evil. This requires the help of Qing Qing who has a strong demonic nature, to gather the necessary Supreme Yin Qi from both of them.

"Then what else are we going to do?"

The black clothed man waved his hand and said, "No matter how the Demon Subduing Array changes, all you need to do is maintain your figure and not leave your own formation core. The rest will be fine, as long as the Heavenly Dipper Sword is activated, a mere Demon King will be killed in seconds."

"Killing the Monster King won't be a problem. Will it harm the soul it devours?" Since he had taken the True Jade Temple Master's purple gold gourd, he had to do something for him.

"Don't worry, the Demon Subduing Formation will lock onto the Demon King's true body. It won't harm the other souls. This is also the Demon Subduing Formation's strength. It has both Yin and Yang auras, so it will naturally be able to determine the true evil spirits."

I heaved a sigh of relief. "Then I am relieved. Many thanks to Uncle Black Cloak for his help. After we get rid of the Monster King, I will definitely invite Uncle out to get drunk for a few rounds."

"You're the one who said that. It's been so many years since this uncle had the smell of alcohol. This time, I'll definitely drink until my fill, haha."

Qing Qing took the opportunity to recover while sitting on the ground. As for me, I don't have any pain nor sickness, so I don't need to pack anything. I just need to continue cultivating my Qi Method.

Around two in the afternoon, we excitedly arrived in front of the Monster King's cave with victory within our grasp.

This time, his arrival was completely different from before, especially Uncle Black, every time he came to the Monster King's cave, his biggest gain was killing the monster created by the Monster King, but he had no way to deal with the Monster King, so over time, he lost any thoughts of killing him.

However, this time was different. As long as he perfectly activated the Heavenly Dipper Demon Subduing Array, he would have a great chance of defeating or even killing the Demon King. For Uncle Black Cloaked, this was a type of release, and he would no longer have to stay in Thunderclap Mountain.

I, on the other hand, am very happy. After killing the Monster King, I can find the Tranquil Heart Grass and also help Aunt Caiyun take her revenge.

Just as we stood at the entrance of the cave, the Monster King's voice came from inside, "Why did you two little fellows come back … Un, isn't this the smelly Daoist Priest? What are the three of you planning to do? "

"Brother Monster King, I didn't expect to meet you again, right? This time, I won't just kill a few of your subordinates. I'm going to uproot you."
