In the end, the two sides divided into two demon cultivation armies, and attacked Yan Song at the same time, so that they could share the resources of the Demon Yuan Crystal Vein.

After Yu Si's words, You Ranfeng immediately discussed with You Chuan, and immediately deployed the demon cultivator according to Yu Si's suggestion.

You Heng was the pioneer, leading 100,000 demon cultivators, and 20 high-level powerful demon cultivators, and set out to conquer the Heavenly Demon Pass. Guarding both sides of the Immortal Demon River to prevent the invasion of the Demon Cultivators sent by Wanyan Song; the second way, send 100 high-level powerful monks and 10,000 demon cultivators to divide into two columns, half to guard the north slope of the Immortal Demon Valley, and half to guard the south valley of the Immortal Demon Valley.

Send thirteen heirs to the twenty-two barbarian wildernesses under their jurisdiction to raise demon cultivators. Let all the wilderness enter the preparation situation, and at the same time deal with the demon army that Yan Song may attack, prepare for the Northern Expedition to complete Yan Song.

Although Yu Si didn't know the specific place names, and he couldn't tell who the demon cultivator who called the name of You Ranfeng was, he knew that the purpose of his trip had been achieved. However, how to draw out the Demon Yuan Crystal Vein, and how to form an alliance between You Ranfeng and Lang Xiaotian, this still needs to be further planned by himself.

Chu Zhe and Gongsun Qidang attracted the attention of the Holy Demon City Lord. That Lang Xiaotian quickly got their existence, and the five of them were waiting for their own order to kill Lang Xin. Then, it was to lure the wolf into the Demon Yuan Crystal Vein, and the descendants of You Ran Peak who were about to appear there appeared at the same time as the place where they lost their lives.

When Yu Si was thinking about how to do it next, You Ranfeng asked Yu Si to stay in the Immortal Demon City for a while in the name that it would take time to prepare for the Demon Army, and first not to go east with Gongye Zhixuan.

At the same time, You Chuan was even more afraid that Yu Si would be bored, and informed him that tomorrow would be the day of the thousand-year-old Flood Domain Immortal Demon Auction, and invited Yu Si and Duanmu Fu, who stayed in the Immortal Demon City, to participate.

You Ranfeng even ordered his subordinates to pack a lot of magic yuan spars for Yu Si and give them to him, so that he could take pictures of the items he liked.

Gongye Zhixuan said earlier that there was something to do, and it was inconvenient for You Ranfeng to stay. In the end, Gongye Zhixuan, Chen Feng, and Yue Qingling left the Immortal Demon City first. Yu Si and Duanmu stayed in the Immortal Demon City.

Chen Feng wrote down Yu Si's instructions to ensure the personal safety of Gongye Zhixuan. Yue Qingling was thoughtful, and let Yu Si brand the means of specific actions and the time of implementation. Set up a ban on mysteries, mixed with layers of Qimen Dunjia to hide his true information in a lot of information, only she can sense and understand.

Gongye Zhixuan has not been separated from Yu Si in the past eleven years, but she has not ruined his plan, and she has coldly separated from him on the surface. She knew that what they were going to was the Holy Demon City where Chu Zhe and the others were, and after meeting with him, she took the opportunity to act, waited for his arrival, and started a bloody massacre.

The reason why Duanmu Fu was left was that Yu Si still wanted to use him as a bait to perfect his first and last steps. Duanmu Fu can use the talent of demon cultivation to make a huge change in his external image, even if the Immortal Demon City's protective array can't find out that it's the same person.

Yu Si did not underestimate the IQ of You Ranfeng, a cultivator who had advanced the old demon, he had to always guard against him having other thoughts to cater to himself. Unexpected things are by no means as they appear on the surface, he can't listen to his words, and there are different screenings and graduate school entrance examinations waiting for him.

But Yu Si knew that the greed and cowardice in You Ranfeng's bones were the real reason why his words could form his decision, and it had nothing to do with his own or anyone's advice. Even if he doesn't say it, You Ranfeng can think of it. It's just that his superficial remarks gave him a reason and gave him a cloth to cover his ugliness.

Deep in the tiger's den, he must take advantage of this opportunity, and he must find the propellant that can catalyze the situation that he needs to happen.

At the same time, the Flood Quartet moved. Heavenly Demon City and Venerable Demon City are all sharpening their knives.

In the inner hall of the Heavenly Demon City, an old demon with long eyebrows and a beard covered by black qi was sitting precariously, sensing the jade slip sent by Lang Cang.

In the hall of the demonic aura in the Demon City, the old demon covered in fur and gold silk underwear glared, and waved his giant hand and said: "What Gongye Zhixuan, what human race Yu Si, none of them can run, tomorrow is the Millennium Auction of the Immortal Demon City, you can choose the opportunity to do it yourself." If you don't form an alliance with the old devil, then you will suffer the catastrophe of annihilation!"

......

On the second day, You Chuan sent the high priest to personally accompany Yu Si and the others to participate in the "Millennium Immortal Demon Auction".

The auction palace is fully equipped with defense facilities, and many high-level demon cultivators are appointed to guard it, which can instantly block the passage in and out of the auction palace. So that the person who tries to influence the auction behavior has nowhere to escape, which greatly avoids the occurrence of emergencies.

The powerful deterrence of force, the sophistication and perfection of the corresponding facilities, and the provision of rare items also gave the auction of the long-standing Immortal Demon City of the Flood Demon Clan, which is once in a thousand years, a grand sense of ceremony.

The auction was held in a palace with a huge three-story hall and a splendor hall that could accommodate nearly 10,000 people. Moreover, on the third floor, there are nearly a thousand independent rooms, which are specially created for noble and profound cultivators.

"Yu Daoyou, please enter the 'Demon Heaven Room' to rest! You Mou is on your left side of the 'Demon River Room'. ”

High Priest You Yue said, and the person who followed the Demon Cultivator to guide the way took Yu Si and Duanmu Fu into the Demon Heaven Room.

The walls of the Demon Heaven Room are made of high-level demon cultivators using enchantments, and you can clearly see the situation in the auction hall, and no one outside can see the people who exist inside.

There were already two pretty women waiting at the door, all of them were light and soft, with delicate curves, wearing a thin veil, and their snow-white skin loomed, which led to reverie.

The two women greeted the two of them, knelt on the ground obediently, and made spiritual tea and divided fruits for Yu Si. Giving everything they have, implying that they can do anything for Yu Si and the others.

"There is no need for any service here, go down. Yu Si waved his hand and sent the second daughter away.

Yu Si then released his divine consciousness and sensed the other independent rooms of the auction hall everywhere. However, this enchantment condensed by a high-level demon cultivator was really weird, and his divine consciousness was blocked near it, and he couldn't penetrate into it.

Yu Si carefully probed the room he was in. After a while, he got the enchantment of this separate room as an enchantment barrier that was not guarded by demon cultivators. That is, this enchantment is maintained by the spiritual power of the magic stone. In this way, even if Yu Si's divine consciousness passes through the barrier, no one will know.

He had the idea of calculating what kind of formation this barrier belonged to. Enchantments are a form of simple formation, but they differ in the thickness and flexibility of enchantments. That's because of the different techniques of arranging the enchantment, and the inconsistency of the prototype and category of the formation chosen.

With his powerful divine sense, he enveloped the space he was in as a whole, using points to lines, lines to reach surfaces, and surfaces to explore as a whole.

So, Yu Si moved. He stretched out the index finger of his right hand and poured his consciousness into his fingers. slapped his chest and swung out a rolling spiritual power. He condensed this lot of Yuan Power around his body so that it would not overflow the room, so that the other monks could not feel that Yu Si was performing a spell.

Then, Yu Siyi pointed to the light curtain in front of him, and a mutated Heavenly Demon Finger spewed out silently with an invisible Samadhi True Fire. In order to avoid the sound produced by passing through this knot, Yu Si wrapped the power of spiritual power that was several times the destructive power outside the Heavenly Demon Finger Qi.

In this way, the moment the Heavenly Demon Finger touches the Enchantment Birth Gate, the spiritual power will divide the subtle sounds that could have been generated, and then his spiritual power will touch the Birth Gate, making him accept his will to run the enchantment.

Yu Si was also on a whim, which was the result of his good thinking and the results of his study of formations and prohibitions. This is an experiment with the space he is in before he wants to control the enchantment of the other monks' rooms.

First of all, he concocted the same method, cautiously driving the Heavenly Demon Finger Qi, erupting soft and powerful spiritual power, and controlling You Yue's enchantment.

You Yue and Yi Demon Cultivator were enjoying the service of a beautiful woman in the room, and when they noticed that the light curtain in the guest room was flickering, they both glanced at each other.

"Little prince, do whatever you want in front of the old devil, and the old devil often cultivates twice. The implication was that the demon cultivator's body beside him reacted, and the result of the demonic blood's excitement made the enchantment stir up a little.

"Each other, each other. High priest together?" the little prince had the same thought, and as he spoke, he grabbed the abundance of the beautiful woman beside him with the palm of his hand.

......

So, in the short time that the auction began, Yu Si touched the enchantment of all the separate rooms, so that he allowed his divine sense to pass through unhindered. In this way, all the circumstances of the monk in these thousand separate rooms were in his mind, and as long as he wanted to know, the things in the guest room would appear in his mind.

At this time, in the middle of the auction hall, an old man with a crane hair and a childish face walked up, with a ruddy face and a tough body, and his mad demon cultivation had reached an extremely high level, and Yu Si couldn't even sense it.

At the same time, a powerful aura spread out all over his body, and in an instant, the noisy voice of the monks participating in the auction quieted down, and everyone's eyes fell on him.

The old man smiled and bowed to everyone: "Welcome to the auction of the once in a thousand years in the Flood Domain, as an auction with a long history, it has already broken through the geographical restrictions of the Flood Domain, so that all the monks in the Eight Domains of Kunmiao are coming. This auction is not disrespectful of race, it is not divided into strata, and the highest bidder wins. So ......"

At this point, the old demon paused, and said: "Therefore, no monk is allowed to interfere with the conduct of the auction with any identity, otherwise he will bear the consequences! This conference has carefully prepared a lot of rare things, extremely rare treasures, all kinds of things that monks need. I believe that you will not be disappointed. The old man You Jianghe is the main auctioneer of this auction, and the winner is determined by three hammers. The old man didn't say much about these rules. Now let's ask for the first lot!"
