The dragon-suppressing spiritual iron is not a particularly valuable item. The price of a piece of spiritual iron is only two million crystals.

But that’s just the price it once was!

One hundred thousand years ago, the only mine in the Dongtian Immortal Realm that could produce dragon-suppressing spiritual iron was destroyed. Since then, the dragon-suppressing treasure has almost disappeared from Dongtian.

Occasionally, there are one or two dragon-suppressing treasures, spiritual iron, mostly brought to Dongtian by monks from the other three days.

Speaking of which, the dragon-suppressing power of Taigong Diao, Ning Fan, was not enough to instantly kill Du Zhen, or even the Life Immortal.

Although it cannot kill instantly, it can still exert a great restraint effect on the dragon monks.

If you are facing a fateful demon dragon and use Taigong Diao's dragon-suppressing magical power, you can at least suppress the opponent's realm by two or three small realms.

Even against the Demonic Dragon of the Upper Crossing Realm, it is enough to have a considerable suppressive effect.

Without Taigong Diao, Yao Qingyun would have experienced unimaginable hardships if he wanted to kill all the thousands of crossing true ice dragons here.

With Taigong Diao in hand and a little bit of dragon-suppressing power, Yao Qingyun's situation will be much better.

"That's all, I don't have the Dragon-Suppressing Treasure in hand, so let me borrow your Dragon-Suppressing Treasure for now. You stay here while I break the formation!"

Yao Qingyun shook Taigong Diao, and Taigong Diao immediately turned into a purple-gold snake spear, and its dragon-suppressing power quickly spread to the entire third floor of the underground palace.

Pointing his toes, Yao Qingyun turned into a blue rainbow and flew into the center of the ice dragon formation.

These ice dragons were all in the early stage of Duzhen. After being suppressed by the power of suppressing dragons, their cultivation levels fell to the level of Duzhen and turned into the peak of Ghost Mystery.

But as streaks of purple-gold light swept across, the ice dragons were immediately blasted into pieces of ice and scattered all over the ground.

An hour later, thousands of ice dragons were killed by Yao Qingyun!

Yao Qingyun escaped with a flash of light and flew back to Ning Fan. He was breathing slightly and his chest was rising and falling slightly. It seemed that slaying the ice dragon was not as easy as imagined.

"This palace has lost a lot of mana. It needs to be restored before entering the fourth level."

After returning Taigong Diao to Ning Fan, Yao Qingyun immediately crossed his legs on the ground and took the elixir to restore his mana.

"I will protect you." Ning Fan said.

"You? If Fei He and others catch up, you won't be able to protect me with your little cultivation." Yao Qingyun pretended to be disdainful, but the corner of his mouth raised a vague arc, betraying her.

true emotions.

Ning Fan's act of consciously helping her protect the law probably made her very satisfied...

Yao Qingyun was busy recovering his magic power, while Ning Fan was on full alert, paying attention to the disturbances around him.

Once there is any change, he will take action immediately and use his trump card.

He accompanied Yao Qingyun to break through three formations in a row, and Yao Qingyun broke through three formations in a row. After breaking through three formations, he would change the formation without anyone noticing.

Ning Fan gained a lot of insights about formations during this trip, but he didn't have time to understand them in detail at the moment.

Two more hours passed, and the entire underground palace suddenly trembled slightly.

The tremor was extremely weak, but it made Yao Qingyun open his eyes vigilantly.

At this moment, Yao Qingyun's magic power has not yet been fully restored, but he has recovered a lot. He slowly stood up, but his beautiful eyebrows were frowned.

"I suddenly felt a sense of uneasiness in my heart. The slight tremor just now seems to have come from the first level. Maybe Fei He and others have broken through the first level of the formation. Let's go to the fourth level quickly.

!”

After Yao Qingyun finished speaking, he grabbed Ning Fan, transformed into a green rainbow, and rushed towards the fourth floor.

"Did a fourth person appear..." Ning Fan felt an extremely uneasy feeling in his heart.

The yin and yang locks in the Dantian trembled irregularly.

There is a new arrival in the Six Desires Underground Palace!

Moreover, the new arrival possesses an almost heaven-defying power of desire. Even if he is still on the first floor of the underground palace, he can still remotely induce the Yin-Yang Lock.

This induction is very similar to the induction of the puppet thread of desire, but it is also somewhat paradoxical.

The visitor may be someone who uses the puppet thread of desire to control the group of cultivators, but he may not be...

Feeling more and more uneasy in his heart, Yao Qingyun ran away faster and faster, grabbing Ning Fan's hand and galloping into the fourth floor of the underground palace.

The fourth floor of the underground palace is a whole world of fire.

Above the sea of ​​fire, there were flame giants walking back and forth, each of them had the cultivation level of transcendence.

"This is... a... sea of ​​fire formation... named... named..." Yao Qingyun's tone suddenly became a little abnormal, his voice soft and charming.

Ning Fan frowned. He was holding Yao Qingyun's hand all the time. Naturally, he could notice that Yao Qingyun's palm was getting hotter and hotter after entering the fourth floor of the underground palace.

Looking at Yao Qingyun's complexion, an abnormal flush gradually appeared.

Her eyes seemed to be covered with a layer of mist, blurred and charming.

Her lips were panting, moist and soft, and her breath was like orchid.

This appearance is very similar to the symptoms of her body being broken in the blood pool and the symptoms of lust poisoning!

"You're suffering from lust, right?" Ning Fan asked with a frown.

"Well... I don't know why, suddenly... suddenly... it's... hateful..." Yao Qingyun's chest rose and fell, breathing lightly, looking at Ning Fan with an expression that was a bit flirtatious.

Silk's demeanor.

As soon as she entered the fourth level, her desire poison began to show up faintly, and the seals of her seven-yin constitution were also being swallowed by the desire poison little by little...

She didn't know why this situation happened. There were three powerful enemies of Shekong in the underground palace. Her desire poison happened at this moment. Damn it...

He bit the tip of his tongue hard and let the red blood flow out of the corners of his lips.

Yao Qingyun tried to suppress his desire with the help of pain, but found that he could not suppress the poison of desire in his body.

With so many desires bewitching her body and mind, she looked at Ning Fan helplessly, feeling extremely empty in her heart, as if there was a huge hole that could not be filled and needed to be comforted...

"Don't lose your original intention!" Ning Fan warned Yao Qingyun loudly as he injected the power of magic into Yao Qingyun's body through their clasped palms.

In the past, Ning Fan would have been able to suppress the desires in Yao Qingyun's body as long as he used yin and yang to transform his magic power.

But this time, for some unknown reason, the effect of the Yin-Yang Transformation on suppressing desires was greatly weakened.

Even with Ning Fan's help, the desire in Yao Qingyun's body has not been completely suppressed.

With Ning Fan's help, Yao Qingyun's eyes became slightly clearer. He regained some of his sanity, but his body was still very soft. He could not mobilize even half of his magic power...

"What should I do... with my current... physical condition... I can't break through... the fourth level of the formation..." Yao Qingyun's whole body was so weak that he almost lost the strength to stand.

His hot body leaned slightly against Ning Fan. He felt that Ning Fan's body was so cold, and he really wanted to get closer...

"Is it because the fourth person entered the underground palace..." Ning Fan's eyes darkened, and he faintly noticed that the change in Yao Qingyun's body was related to the fourth person.

If the fourth person has arrived, he doesn't mind returning to the upper underground palace. He sacrifices the jade slips that the Immortal Lord struck and kills Fei He and others in one fell swoop.

A sky-blue rain flashed in his eyes, and a drizzle suddenly began to fall on all floors one to four of the underground palace!

At this moment, Ning Fan's spiritual thoughts extended back to the previous levels.

He saw that in the first floor of the underground palace, an old man wearing a black cloak was making secrets with his fingers and performing the secret technique of desire.

This secret technique is the culprit that activates the poison of desire in Yao Qingyun's body!

Behind the old man in the cloak, Fei He and three other Shekong stood respectfully!

Under the feet of the cloaked old man, trampled on the remains of one hundred and eight golden gods!

That mysterious old man in cloak is in the middle stage of Suinian Nian!

After he arrived, he casually broke through the first level of the formation and rescued Fei He and others. Then he activated the secret technique and activated the lust poison in Yao Qingyun's body.

While he was performing the magic, a drizzle suddenly fell from the sky.

At the moment when the drizzle fell, the old man in the cloak raised his empty eyes. There was a flow of black blood in those eyes. There were no eyes!

"Oh? There is a spiritual thought hidden in this rain. You want to spy on me? Judging from the strength of this spiritual thought, is the caster the container of the peak human being? Humph, he is really a container that does not know how to live or die!"

The old man in the cloak snorted conspiratorially, and a huge force of collapse immediately spread out, intending to crush Ning Fan's spiritual thoughts into pieces in the drizzle.

Ning Fan's eyes were startled, he hurriedly solved the rain spell and withdrew his spiritual thoughts.

Even so, he still took a step too slowly, his spiritual thoughts were crushed a lot, his sea of ​​​​consciousness hurt, and he was severely injured by the cold snort of the old man in the cloak!

With just a cold snort, you can severely damage Ning Fan's sea of ​​consciousness. This is the strength of the Broken Thoughts cultivator!

This person only needs a look or a word to kill Ning Fan. The monk is definitely not something Ning Fan can defeat!

A wisp of black blood mixed with lust and poison flowed out from the corner of Ning Fan's mouth. He wiped it away casually, but a cold light flashed in his eyes.

"You...why are you also poisoned by lust..." Yao Qingyun asked, panting slightly, with concern in his eyes.

She was so confused at the moment that she couldn't hide her true feelings at all.

"The fourth person has entered the underground palace... No, to be precise, this person is not really that person. This person is just a corpse controlled by puppet strings." Ning Fan spoke calmly, activating the power of the Yin-Yang Lock, and locked the body inside.

The poison of desire is instantly eliminated.

He is not afraid of the poison of desire.

"Fourth person? Puppet? Dead body? That is... what... I don't understand..." Yao Qingyun was a little confused again, his mind went blank and it was difficult to think.
To be continued...
