Miss Feng Wu, the female alchemy goddess, is busy refining alchemy

Looking at these monster-like things in front of them, everyone's expressions turned ugly. A sudden scream completely broke the silence.

Everyone looked towards the place where the sound came from, and it turned out to be a demon boy sneaking up on a monk.

The long nails on its slender fingers rubbed directly into the disciple's head. In an instant, it sucked all the spiritual power out of him and turned his body into a mummy at an extremely fast speed.

Everyone was staring at the demon boy closely. The alchemist's elixir fire consumed a lot of spiritual energy. Fortunately, they all had no shortage of spiritual elixirs. Now they couldn't care about anything and just took out the entire elixir bottle and poured it into their mouths.

The demon boy was afraid of the strange fire and kept hovering around them, waiting for them to run out of spiritual power. Occasionally, they could sneak attack one or two disciples.

They couldn't stay in place and needed to escape as soon as possible, but the devil boy in front of them forced them to move deeper.

Moving slowly, he unknowingly saw an empty room at the end, with a coffin placed in the middle.

The lid had been opened and thrown to the ground. A black-clothed demon cultivator sat cross-legged on top of the coffin, and a dozen demon cultivators stood respectfully beside him.

Feng Yunzhao's eyes flickered when he heard them calling him Demon Lord. He couldn't be the one he met before, right?

She secretly observed the surrounding environment. The reason why she didn't take action just now was because she wanted to go deep into the cave to see what their purpose was.

She silently observed everything around her, secretly calculating the location of the exit. The demon king spoke directly:

"I didn't expect that just releasing the news of the secret realm would attract so many monks. I underestimated your greed. Even the heads of some sects want to participate. Very good, this time can greatly increase my skills."

The demon cultivators beside him all congratulated:

"Congratulations to the Demon Lord for his great work. The Demon Lord's magic power is boundless and spans the continent."

The shouts shook the entire tomb, and the demon boys above them also made cheers, but the sounds they made were particularly harsh.

Everyone looked at the Demon Lord nervously. Since he was a Demon Lord, it meant that his cultivation level must be very high. Originally, demon cultivators were one level higher than monks at the same level because of the evil nature of their skills.

The demon king's strength should be at least at the Nascent Soul stage. Several sect leaders and elders made eye contact and saw fear in each other's eyes.

The demon king suddenly stood up. Behind him, a stone door slowly opened, and what appeared in front of everyone was an unforgettable scene.

In front of you is a tower made of skeletons that reaches as high as the top of the cave. The heads are built in a hexagonal shape, but there is an empty space in the middle. Through the gaps between the skulls, you can see something glowing red inside.

When everyone saw so many skeletons, they were not only shocked but also frightened. The demons had been here for who knows how long and killed so many monks.

Why didn't they get any news before? Could it be that someone deliberately concealed the news here? Thinking that this was the territory of the Kunlun Sect, a chill ran down their backs.

Could it be said that demonic cultivators have already infiltrated into the sect, and if the first-class sect is like this, let alone them? At this moment, they desperately wanted to break out and alert the people outside, but even their chances of survival were slim.

Feng Yunzhao watched the demon king prepare to cast a spell, and finally understood that the bone tower was built for him to practice magic skills, and his conspiracy could never succeed.

Seeing everyone's spiritual energy being consumed little by little, with the demon boy above her head ready to attack at any time, she directly swallowed a bottle of spiritual elixir and began to form seals with her hands.

She must not underestimate the enemy when dealing with such a high-level demon cultivator. She plans to use her Mysterious God Technique and the Immortal Grade Skill Fire Tree and Silver Flower to eliminate these demon boys.

Her hands were quickly forming seals, and the remaining images were glowing red. As she shouted "Fire Trees and Silver Flowers", countless small sparks were seen flying everywhere.

The cave instantly became as bright as day, making it difficult to open their eyes. The flying sparks fell on the demon boy, and they didn't care at all at first.

But slowly the sparks grew bigger and turned into flames, burning them until they screamed in pain. Only then did the surrounding demon cultivators notice the difference.

The Demon Lord's movements were interrupted and he looked towards them displeased, but what he saw was the Demon Child wailing in pain with an incredible look on his face.

But soon he discovered something strange,

"You actually have divine fire? Who are you?"

Staring at her with murderous intent in his eyes, Feng Yunzhao would not answer his question at all, and said to the monks present:

"You must no longer hold back, work together and rush out. If he succeeds in becoming a demon, none of you will be able to leave today."

Perhaps because the technique just now was too shocking, the monks' hearts were instantly full of morale, and they took out all the treasures they had packed at the bottom of the box and prepared for a fight to the death.

Seeing this situation, the Demon Lord looked slightly mocking.

"It is simply overestimating your ability to escape with just this little divine fire. Let you take a good look at how you died here."

As he spoke, he saw him cut his palm, black blood dripping into the lines on the ground, and dark red formations suddenly rose around him.

They were completely surrounded by it, feeling the surrounding air squeezing their chests and making it difficult to breathe.

The spiritual energy in his body was passing away rapidly, and some disciples with low cultivation levels were visibly getting older and dying.

A bright red blood line jumped out from their heads and sank into the formation. The red color in the middle of the Demonic Bone Tower seemed to be shaking slightly.

Feng Yunzhao used the Xuan Shen Jue to take out six Explosive Fire Pills with both hands, and used the Phoenix Divine Fire to throw them directly at the center of the formation. A huge explosion sounded that made his ears buzz.

The ground finally stabilized after a violent shaking. Most of the surrounding monks were hit by the explosion wave and fell to the ground.

Some demon cultivators also fell to the ground, and some demon cultivators whose formations were broken were stained with divine fire and could only be burned alive.

Seeing this situation, the Demon Lord was completely angered, and his eyes became even more blood-red as he stared at Feng Yunzhao.

"You actually broke my demon clan's formation. You really underestimated the people here."

After saying that, he began to wave the seals with both hands, thick black demonic energy emitted, and the surrounding stone walls began to seep demonic energy.

Once the demonic energy penetrates into the disciple's body, the monk will soon scream in pain and bleed to death. Feng Yunzhao also frantically throws explosive pills to eliminate the demonic energy.

The alchemists present also took out their own fire elixirs to help out, and for a moment the surroundings were filled with flames and thick smoke.

The surroundings were slowly surrounded by smoke, and at this time Feng Yunzhao suddenly took action and rushed towards the Demon Lord's position.

With the Phoenix Divine Fire attached to her hands, she swung a palm in the direction of the Demon Lord and hit the Demon Lord's chest. She heard a muffled grunt that must have hit him.

He held the Immortal Phoenix Fan in his hand and waved it around a few times, immediately igniting a cloud of smoke and fanning it away. He saw the Demon Lord covering his chest and preparing to retreat to the tower.
