"What's going on?"

All the monks also understood the situation in the inner valley of the Spiritual Medicine Valley. Under the permeation of demonic energy, a simple gathering consciousness was also transmitted from the deepest part, so many demon corpses were crazily attacking the formation light shield in the center of the area, thus trying to enter the next level area.

Therefore, Yun Yifei naturally believed that except for the formation in the central area where there was a demon corpse, other places were safe.

The Baibao Taoist naturally understood Yun Yifei's meaning and immediately said: "Although the demon corpses are concentrated in the center, the Yin-Yang twin leaves also grow in the center, not far from the formation."

"And there are many spiritual medicines distributed in other places. Although they are not as valuable as the Yin-Yang Twin Leaves, they should be of great value. Don't you want to pick them together?" The Taoist Baibao continued, with a little playful tone.

"Go directly to the Yin-Yang Twin Leaf," Yun Yifei said after hesitating a little. He was a cautious person and strived to be safe in his work. Moreover, the Yin-Yang Twin Leaf is the thing he needs most. As for other spiritual medicines, whether they are used to refine alchemy or replaced with spirit stones, they are not important things to him.

The demon corpses gathered in the central area, and the monsters were dormant, so everyone was free of scruples and rushed towards the central area without any scruples.

This area is much wider than the previous layer. Yun Yifei looked down at this area covered by demonic energy in mid-air, and the information about the formation surging in his mind. Judging from the recent two layers of formations, there must be space effects in the formation.

This is why from the outside, the formation only covers a small area, but the space can be expanded many times after entering the formation, but there is no space restriction in the formation information obtained.

The monks rushed all the way without stopping. After a few hours, they arrived in a wide valley. There was a peak standing in the middle of the valley. The peak was not very high, only more than a hundred feet away.

The top of the mountain was flat and wide. The monks saw more than a hundred demon corpses attacking a formation light cover frantically. There was only a simple and simple stone platform built inside the formation light cover. It was thought that was the passage to the next level.

The demon corpses had no time to take care of each other. Even though the monks flew to the nearest of the mountain to observe, the demon corpses only took a look and still attacked the formation.

"Lingling..."

The bell sounds clear and not loud, but it can clearly reach a long distance.

Yun Yifei looked down and saw the four monks at the edge of the valley, controlling more than a dozen demon corpses moving forward with difficulty towards a place near the mountain wall.

Because the demon corpse was tall, Yun Yifei could not see the spiritual consciousness spreading out in front of the mountain wall, but found that a strange energy spread out not far from the mountain wall. At first he thought there was a formation there, but at this time he found that this energy was not a wave of the formation, but a relatively special existence. As for how special it was, he couldn't say it.

"Is that the place where the yin and yang twin leaves grow?" Yun Yifei thought about it and suddenly thought of something.

"That's right", the voice transmission of Baibao Taoist confirmed Yun Yifei's guess.

"Why can't you see the yin and yang twin leaves?"

"The twin leaves are shrouded by the yin and yang power emitted, which can naturally block the eyes and spiritual consciousness."

"Can it be so magical? That kind of energy fluctuation is the power of yin and yang." Yun Yifei was a little shocked when he heard this.

"That is, all things have spirits, and spiritual medicines naturally have means to protect themselves."

After a brief discussion, Chu Tianfeng and others lowered their escape light and attacked the four masked monks.

The four monks naturally discovered that Chu Tianfeng and others flew here. At this time, several demon corpses were guarding the four of them. When they saw everyone attacking, they took action to stop the attacks.

"Lingling..."

The four monks were extremely cautious and retreated in a flash. At the same time, the corpse control bell was shaking gently. The demon corpse, which was moving forward against the power of yin and yang, retreated instantly and attacked Chu Tianfeng and others.

Chu Tianfeng and others have all returned to their peak state. Although they have galloped all the way, they have no effect. At this time, they have a sharp attack and have fought fiercely with more than a dozen demon corpses in an instant.

From the outer valley of the Spiritual Medicine Valley to the area where the inner valley is progressing layer by layer, the power of the demon corpses is getting stronger and stronger. The monks naturally know that, although they are prepared in their hearts, the attack methods and power of these dozen demon corpses are still shocked by everyone.

This is not like a demon corpse that has lost its life. It is clearly a demon beast with clear mind. Facing the attacks of everyone, I know how to avoid the edge, I know how to judge the situation, and I also know how to cooperate with other demon corpses. This has never been encountered before.

Everyone has encountered many demon corpses before, and there are times when the number of demon corpses is several times that of cultivators, but everyone can kill them all. Most of them are because the demon corpses only know how to attack wildly without knowing how to dodge and adapt.

Although as everyone went deeper, the demon corpses they encountered gradually gained simple consciousness and thinking, compared with these demon corpses now, they were like small witches and high mountains.

Therefore, the monks were under great pressure at this time and did not dare to be careless at all. Fortunately, they only had a dozen demon corpses, and they could deal with them with the means they could use.

After about a quarter of an hour of fierce fighting, although the demon corpse and the monks had the upper hand, they could not cause overwhelming damage to the other party, so the battle situation was stalemate.

"The dragon penetrates the clouds"

"The dragon goes out to the sea"

"The strong dragon shakes the earth"

"Two Dragons Draw Water"

Yun Yifei thought about the Yin-Yang Twin Leaves, and in a hurry, he punched four times to assist Chu Tianfeng in killing a demon corpse at a disadvantage. As a result, most of the power in his body was consumed and he couldn't help but breathe slightly.

"Junior Brother Lin set up the formation", Lin Yuxi said.

Yun Yifei felt a bright heart when he heard this, and secretly scolded himself for being stupid. Why didn't he expect it? Then he stopped delaying and took out a slap of array flags and array plates, calculated the position, and quickly arranged it.

With the cover of Chu Tianfeng and others, Yun Yifei was not worried about safety issues. It didn’t take long and the arrangement of three sets of formations was completed.

The Great Illusion Ethereal Array.

The big waves of sand washing array.

And a set of Bagua defense arrays.

The monks enter defense

Within the scope of the imperial formation, the Great Fantasy Emoji Array and the Great Wave Sha Array launched a fierce attack on the demon corpses inside it, and the effect was immediate.

The Great Illusion Ethereal Array is an Illusion Array. Although the demon corpse here has conscious thinking, it is a dead object after all. Naturally, consciousness is somewhat depleted than before in his lifetime, so it is easy to fall into the influence of the Illusion Array. Moreover, even the lively monsters are not as complicated as the thinking of human cultivators, and naturally they have less self-control.

When the demon corpse is confused, running wildly, or attacks randomly in the great illusion array, the attacks of the monks will subdue it, thus destroying its shriveled or skeleton body.

There is no need to mention the Great Wave Sand Washing Formation. Yun Yifei had seen the power of this formation before. The demon corpse was swept into it by the surging waves. Before he could struggle, the attacks of the monks had arrived, helping the waves to erase them together.

The monks were at this time without any pressure. They took action and wiped out the demon corpses shrouded in the formation in less than half an hour.

At this time, the four monks were standing five demon corpses before. It was only when the four of them saw Yun Yifei setting up a formation and controlled them in time to save the five demon corpses.

"Lingling..."

Four monks jumped onto the back of the demon corpse, and the corpse control bell shook lightly. The five demon corpses climbed towards the peak at a speed. In an instant, they had reached the top of the mountain, overlooking Yun Yifei and others.

Yun Yifei discussed with everyone, took out the array flag array plates of the three sets of formations, and arranged them in front of the Yin-Yang Twin Leaves.

"The spiritual medicine here is what I need, and I will hand it over to you."

Then, Yun Yifei moved towards the place where strange energy was emitted. Although he could not see the yin and yang twin leaf, the energy emitted could still roughly determine where it grew. It was at the center of this energy fluctuation without thinking.

As soon as Yun Yifei entered the cover of strange energy, he felt a pressure coming, as if he was in a swamp, and a sense of blockage bound his body, making it difficult for him to move forward.

Not only that, this energy also directly acts on the body. The body feels painful as if it is crushed by force. Fortunately, Yun Yifei absorbed the drop of blood of the dragon crocodile, and his body has become much stronger and he can temporarily withstand this pressure.

Yun Yifei gritted his teeth and walked forward for more than ten steps. This powerful energy changed without warning and turned into another completely different energy.

Yun Yifei only felt the pressure in his body relaxed, and before he could be happy, he felt another feeling coming. Although this other energy reduced the pressure around him, it could directly penetrate the body, with the muscles, bones, flesh and blood, and various organs of the body, and even had no way to resist.

"puff"

The sudden conversion of two completely different energy made Yun Yifei unable to help it. He spurted out a mouthful of blood and hurriedly used his spiritual power to control his injuries and resist the omnipresent energy.

This energy spread throughout the body and quickly activates spiritual power, but it is several times more difficult than usual. Fortunately, the pressure on all parts of the body has been reduced a little.
