"Yi Mu Yin Thunder Formation, condensing Yi Mu's Qi, condensing Soul Evil Qi, although this method is wonderful, it is too sinister after all..." Looking at the five Yin Thunder Flags in front of him, Zhou Yu's eyes were a little thoughtful.

But then a smile quickly appeared on his face. Although the spirit of soul evil is too fierce and is often refined with raw souls, if you encounter those ferocious monsters in the future, you can use it.

"What's more, there is a lot of this energy in those Demon Sect disciples." As soon as he thought of this, Zhou Yu suddenly felt relieved.

After all, the power of this thunder method is quite strong. Although he will not deliberately collect it, he is prepared for any danger.

An hour later, Zhou Yu mastered the method of refining the Yin Thunder Beads and how to cast the Yimu Yin Thunder Formation. After all, the most difficult part of this formation was condensing the Yin Thunder Beads.

As for the Yin Lei Pearl, the most important thing is Yimu Qi and Soul Evil Qi. The refining method is not too complicated, otherwise it would not be mastered by a few monks in the late stage of Qi Training Realm.

The only thing that makes Zhou Yu a little regretful is that this Yimu Yin Thunder Formation cannot be used as a reference to the Qingxuan Sword Intent.

Although his Wooden Sword Intent was realized by observing the sky-reaching building wood, and it has an intention to reach the sky, it is too weak now. Compared with other kinds of sword intent, it is dead wood, and it is difficult to exert much combat power at the moment.

"Since the Rebirth Cult is still looking for tree demons to kill, it seems that even if it is not close to the core of the sacred tree mountain, it is not far away. Now is not the time to delay enlightenment."

After burning a stick of incense, Zhou Yu, who had completely adjusted his breath, quickly flew towards the place where the power of the wood in Shenmu Mountain was strong.

…

Shenmu Mountain, in front of a canyon crack.

At this moment, there was a middle-aged man in purple and black standing with his hands behind his back. Where he looked, five Taoists riding on the first-order monster Black Feather Eagle were flying quickly.

"The right banner guard pays homage to Mu Xing." As the five monsters landed, among the five, a young man with a small flag painted on his chest immediately said respectfully to the elder in purple and black robes.

"These are the four pieces of dryad hearts that my subordinates hunted. Please check them, sir." After saying that, the right flag guard took out four pieces of cyan wooden boxes from the storage bag and handed them over.

"Not bad." Mu Xing opened one of the wooden boxes and felt the pure power of Mu Xing inside. His solemn expression softened. As he put it away, he walked towards the cracks in the canyon.

"Follow me."

"Sir, why don't we wait for Zuo Banwei? Judging by the time, he must have achieved good results?"

"He is already dead, along with the other four people, just three days ago." Mu Xingxing said calmly without looking back, but the right flag guard was stunned and felt something in his voice.

An angry look.

"The Zuoqi Guards are not weak in cultivation. With the other four disciples, even if they cannot kill the tree demon, with the Yimu Yin Thunder Formation given by the Lord, they can at least escape unscathed. Could it be that they are the ones who want to defeat the Demon Division?"

Caught up?" The right flag guard said cautiously as he followed, his expression gradually becoming serious.

"No matter who it is, the top priority is to enter the wooden palace in this canyon as soon as possible, join the protectors and the others, and obtain the talisman in the mountain. After obtaining the talisman...

Huh, anyone who dares to touch me, Meng Xing, whether it is the Demon Master or someone else, will have to pay the price." After saying that, Muxing took a big step, and his figure disappeared into the crack in the canyon.

Stepping into the crack, the right flag guard suddenly felt that his entire vision was darkened, but not long after, after walking through a long and winding canyon, there was a burst of light in front of his eyes.

A huge valley appeared in front of several people. Within the valley, there was a magnificent square, with one after another huge stone pillars wrapped with vines.

In front of this magnificent square, there are more than ten people waiting at the moment. The leader of them is wearing an evil tiger mask. Next to him, stand the beast guard Wang Quan and the earth in the mouth of the Corpse Yin Sect.

Flow, now the dead body of the Rebirth Cult is an iron corpse.

"You're late, but what happened?"

"Please forgive me, Lord Protector. Unfortunately, a small group of people led by my Zuo Banner Guard were martyred. Fortunately, the required Dryad Hearts are already available." Looking at the man wearing the evil tiger mask in front of him, Mu Xing

Meng Xing said respectfully.

"It won't happen again, let's start now." Evil Tiger said in a low voice.

…

Half a day later, a ray of light suddenly flashed across the canyon, and it turned out to be Zhou Yu.

"Is this here?" Looking at the cracks in the canyon in front of him, and feeling the pure wood spirit energy in his body, Zhou Yu's eyes suddenly became solemn.

"Next time, if my uncle is looking for me to do something, he will have to ask them for a map." Zhou Yu swore in his heart as he thought about the continuous search on Shenmu Mountain for the past three days.

The next moment, his body moved and he stepped into the crack in front of him.

Soon, a huge square appeared in front of him, with a coiled dragon pillar on it, just like the Shenzawa Temple he had seen that day.

At the same time, on the rocky walls surrounding the valley in front of me, there were countless green vines spreading like giant pythons, which was quite astonishing.

And on the huge square in front of us, there are even broken tree trunks, as if there had been a war not long ago.

"It seems I've found the right place." Seeing this scene, Zhou Yu narrowed his eyes slightly and immediately walked towards the square.

Judging from the traces left on the square at this moment, it seems that the battle broke out extremely quickly and continued into the huge cave in front of the square.

"The traces of the battle are messy but orderly. It was obviously a sudden battle, but was quickly suppressed, and more than one person passed through." Walking all the way to the center of the square, Zhou Yu looked at the collapsed stone pillars and collapses around him.

The broken stone slabs, with a solemn look in his eyes.

Soon, he stepped into the cave.

It is said to be a mountain cave, but in fact the inside of the mountain seems to have been hollowed out. It is more like a palace built out of the entire mountain, and the internal space seems extremely huge.

More importantly, a large amount of light poured in from the top of the cave, making Zhou Yu's field of vision extremely bright as he walked.

Not long after, he entered a place that looked like a hall, but the traces of the battle were more obvious at this moment. In this wide hall, there were dozens of broken puppets and the dead bodies of monsters.

, scattered everywhere.

It was obvious that they had gone through an extremely intense fight.

"Mu Xing is right. Sure enough, someone may find this place." Just as Zhou Yu was carefully looking at everything in the hall, trying to further judge the next step of the Rebirth Cult, a gloomy voice suddenly came out.

Ten feet away in front of him, within a broken shadow, a man in black robes suddenly appeared.
