Some of the alchemists are spirit stones, not to mention the grandmaster-level alchemists, and in the end, the price of Chu Chen's Yan Dan exceeded 10 billion!

This figure surprised Chu Chen, he thought that this bottle of high-grade Zhuyan Pill would be about five or six billion at most, but who would have thought that in the end, it was auctioned at a price of ten hundred and one billion, and it was taken away by a person on the sixth layer, the chief alchemist of the Bright Sect. After the spirit stones obtained from these auctions, after the Drunken Immortal Building took one-tenth of the commission, Chu Chen finally got more than ninety and one spirit stones, this windfall made Chu Chen quite surprised, and at the same time, in his heart, he already had an idea, in the future, he would pick up the people of the Tianchen Sect, I am afraid that he could directly sell the pills to feed the people of the whole sect.

After the auction ended, Chu Chen drank for a while before returning to the guest room; after entering the guest room, Chu Chen did not go out again, and he did not leave the Drunken Immortal Tower until the inner city formation of the Underground Demon City weakened.

The entrance of the underground demon city, five hundred miles east of the demon slaying city, out of the demon slaying city about thirty miles away, is the forest, to enter the underground demon city, you must pass through this hundreds of miles of forest, if you want to pass through the forest, you can only walk in, because for a long time, anyone who is close to the underground entrance defense for hundreds of miles is not able to fly in the air, no one knows why, when Chu Chen first came to the underground demon city in the previous life, he didn't know why, and then he came back from the upper realm, and he completely figured out what was going on.

Within a radius of hundreds of miles from the entrance of this underground demon city, there is an extremely secret force, so that the monk cannot fly, just like the forbidden air ban is arranged within hundreds of miles of this underground demon city, this hidden power is very powerful, and if the cultivation does not reach the third step, it is impossible to detect this power at all, this power is penetrated from the underground demon city, and later Chu Chen carefully inspected it, only to find that this hidden power comes from the power of those ancient formations in the underground demon city, to be specific, it is the power of the forbidden sky formation in the underground demon city that penetrates out, so that it is impossible to fly in the sky within hundreds of miles。

Chu Chen walked alone on the road, today is the time when the formation and prohibition of the inner city of the underground demon city are weakened, so there are many people who go to the underground demon city today, and the entire demon city has almost become an empty city; Chu Chen's speed of walking all the way is not fast, many monks have easily surpassed him, only to see the pedestrians on the road in a hurry, without the slightest intention of stopping, one by one they just want to reach the underground demon city quickly, so that they can go into the inner city to try their luck, maybe they will become rich one day.

Chu Chen walked alone on the road, walked for almost an hour, he came to the forest, and then did not hesitate, walked straight in, as soon as he entered the forest, the sun was immediately covered by the sky and ancient trees, for a while, the forest seemed quite dark, from the entrance of the forest to the entrance of the underground demon city, it had already been stepped out of a avenue by the monks, Chu Chen looked at this familiar road, and couldn't help but remember the scene of the first time he came here in his previous life, at that time, he did not come alone, but followed others, but at that time it was not the formation of the inner city of the underground demon cityWhen the ban weakened, the first time he came, Chu Chen completely satisfied his curiosity, but who would have thought that the people who came with him would actually want to kill him, and in the end, Chu Chen was chased and killed by several people, and had to flee into the inner city of the underground demon city, fortunately, God blessed, he was forced to flee into the inner city of the underground demon city, thinking that he was only afraid of nine deaths, but who would have thought that he actually obtained the inheritance technique of the old man of the heavenly illusion in it, and in the end, not only did he not die, but his cultivation rose sharply, and finally went out and killed those who chased him.

After walking in the forest for most of the day, when it was dark, Chu Chen came to the entrance of the underground demon city, this place is a sinkhole, the radius is almost a thousand zhang in size, the bottom is not visible, the underground demon city is under this sinkhole.

When Chu Chen came here, there was no one at the entrance, Chu Chen did not hesitate, and walked down the sinkhole in one step, the sinkhole was very deep, almost ten miles deep, and it took Chu Chen almost a cup of tea to fall at the bottom.

The underground is not pitch black, but like the light in the evening, because, on the walls of this underground, there are a lot of moonstones embedded, Chu Chen fell at the bottom, and what caught his eye was a passage the size of a hundred zhang, I don't know how long.

Chu Chen walked forward along the passage, and after walking for about a few miles, a huge underground city appeared in his divine sense, at this time, outside the city gate, almost 200,000 monks had gathered, most of these people were from the Youming Sect, of course, there were also a small number of monks from powerful sects from other continents, although there were so many monks gathered outside the underground demon city, but they did not gather together, but divided into many groups, they were scattered around the city gate, and those who could get close to the city gate were all disciples of the nine major forces, among them, Chu Chen saw Pan Decheng and some elder-level figures of the Wuji Sect, in addition, He also saw Lan Yiyi and some elder-level figures of the Bright Sect, they were waiting for the prohibitions and formations in the Demon City to weaken, but, with Chu Chen's eyesight, he could see at a glance that it would take at least half a day for the prohibitions and formations in the Underground Demon City to weaken, and he didn't want to wait for half a day, not to mention, he knew everything about this underground Demon City, what formations and prohibitions he knew all about, and he didn't need to wait that long at all, so he walked into the gate of the Underground Demon City alone under the watchful eye of everyone, but when he walked in, he was suddenly stopped。

"Eh, who are you, do you want to die when you walk ahead of us?!" In the face of such a threat, Chu Chen paused, slowly turned around, and looked at the person who threatened him just now, this person was a person from the Wuji Sect, and he had been following Pan Decheng's side, however, Chu Chen just glanced at that person, and then his eyes fell on Lan Yiyi's body, and after looking at her, his eyes returned to the face of the disciple of the Wuji Sect.

"The seniors are angry, there was a lot of offense just now, and I ask the seniors to see the face of the Wuji Sect and not to be like the junior disciples. "Chu Chen has never exposed his cultivation, and he usually goes to cultivate, so when he came over just now, no one paid attention to his cultivation, at this time, Chu Chen's appearance naturally surprised many people, especially the disciple of the Wuji Sect who threatened Chu Chen just now, he was not afraid of the Tribulation Period Cultivation, and dared to speak to a Heaven Breaking Realm cultivator like this, if there was no elder of the sect at this time, it was estimated that he would already be a dead man at this time.

"Wuji Sect?" Chu Chen sneered: "Don't provoke the deity, otherwise Pan Huang of Wuji Sect won't be able to save you!"

Pan Huang, is Pan Decheng's grandfather, the ancestor of the Wuji Sect, and a great monk in the early stage of the Heaven Breaking Realm, but now he rarely appears in the outside world, under normal circumstances, he is sleeping, trying to let Shouyuan lose as little as possible, and now, I am afraid that few people will see him.

"Presumptuous, dare to call the name of the ancestor of my sect!" After Chu Chen said this, an elder of the Wuji Sect immediately shouted at Chu Chen, in the Wuji Sect, the name Pan Huang cannot be called directly, and all the disciples must respect and call 'Old Ancestor'.

"What, do you want to fight?" Chu Chen glanced at the elder and asked lightly.

"You!" This elder has a very impulsive temper, if it weren't for an elder of the Wuji Sect next to him who immediately grabbed him, it is estimated that he would really have a big fight with Chu Chen, however, Chu Chen is not afraid at all in the face of these monks of the same level, even if the four elders of the Wuji Sect come here together, he can kill them, but the Wuji Sect and other big forces have always been in the same breath, and with his move, it is estimated that the monks of the other forces will not be able to sit still, and they are afraid that they will attack it in groups, but even so, Chu Chen can still escape if he can't win, he also knows that now is not the best time to make a move, and when he arrives in the underground demon city, it is the best time for him to make a move, and when the time comes, these big forces peep into the heavenly realm, I'm afraid that they will be left in it and will never be able to get out.

"Hmph!" Chu Chen snorted, turned around and waved his sleeves, and walked towards the city with his right hand behind his back, at this time, everyone knew that Chu Chen was going to enter the city, not to seize the first position.

In front of everyone's eyes, Chu Chen disappeared at the gate of the city, and as soon as he entered the city, everyone's divine consciousness could no longer lock Chu Chen, because, once he entered the underground demon city, his divine consciousness was greatly suppressed, and the divine consciousness of the monks during the tribulation period could only release about ten zhang, the monks of the Mingxu Realm could release twenty zhangs, and those who peeped into the heavenly realm could only release thirty zhang, and no matter how far they went.

Chu Chen walked into the city, only to see that there was still a faint demonic qi flowing in the city, and the whole city was shrouded in a faint mist, however, as soon as he entered the city, it did not become dark, but it was almost the same as outside, the streets were empty, most of the buildings had become ruins, the streets were messy, and from time to time you could see some white bones, and from time to time you could see some broken weapons.

Chu Chen walked on the terrifyingly quiet street, in addition to seeing white bones and broken weapons from time to time, he could also be attacked by magic weapons and supernatural powers on the ground, this is a giant city left over from a brutal war.

This underground demon city is almost a thousand miles in size, and it is boundless. Chu Chen walked on the street according to his memory, when he walked more than a mile, he turned his direction, walked into another street, and then kept walking, avoiding a lot of prohibitions and formations along the way, and finally, he stopped in front of a huge mansion, according to Chu Chen's understanding, the mansion here should be the mansion of a demon handsome level figure in the demon clan, but now, this mansion has been dilapidated, Chu Chen walked in, passed a few ruins, and finally came to a well-preserved house, the door of the house was hidden, Chu Chen easily pushed the door in, in the hall of this house, he saw a skeleton sitting cross-legged there, this skeleton, It is the Heavenly Illusion Old Man, this Heavenly Illusion Old Man has no injuries all over his body, Chu Chen is sure that the Heavenly Illusion Old Man died of the exhaustion of Shouyuan, of course, how the Heavenly Illusion Old Man died, it is recorded in his Codex, Chu Chen speculated so before he saw his Codex.

"Heavenly Illusion senior, we meet again, in my previous life, thanks to your inheritance, I was fortunate to reign in the world and step on the position of Immortal Venerable. Chu Chen walked up to the bones of the Heavenly Illusion Old Man and bowed to him. After Chu Chen got up, he put away the bones of the Heavenly Illusion Old Man, and when he got outside, he found a feng shui treasure place to bury him, and let him be buried in the ground, which could be regarded as repaying the kindness of the teaching in his previous life.

This time, Chu Chen's purpose in coming to the underground demon city was only two, one was to take the old man of Heavenly Illusion out and put him in the earth for peace, and the other was to kill a few more of the peeping heaven realms of several major forces, so that their strength would be greatly damaged, and they would not dare to easily encroach on the territory of his Tianchen Sect, although Chu Chen didn't care about those territories, but he couldn't let them encroach endlessly, otherwise Huo Juan Peng and they would have to fight with them.

If there was really a fight, Chu Chen's original plan would be in vain, and he didn't want his plan to be in vain.

Walking out of the mansion, Chu Chen felt the power of the surrounding formations, and knew that the power of these formations was slowly weakening. "Now that the first thing has been done, the next thing is to play with you slowly. A sneer appeared at the corner of Chu Chen's mouth, in this underground demon city, even if the Heaven Breaking Realm cultivators came, Chu Chen was sure that he would solve them quickly.

As soon as his body moved, Chu Chen flew onto a house, and then quickly rushed to the gate of the city, at the same time, he blessed himself with a stealth technique, so that his body disappeared, in this underground demon city, no one can fly, even if he can fly, it is already the top of the sky to be able to fly one zhang high, ordinary monks can only fly five feet high, but Chu Chen is different, he can withstand the forbidden sky array in this underground demon city, because his physical strength is not comparable to ordinary monks, although this consumes him a lot, but it can be used in exchange for speed, so that he can lay out in advance, and introduce the person to be killed step by step。

With the weakening of the power of the formation prohibition in the underground demon city, the people of the major forces have entered the underground demon city, of course, the first to come are those who are super forces, and then those who are the top first-class forces, the third group is those who are first-class strength, and the last to enter the underground demon city are those who have no background.

Chu Chen didn't take long to come to the vicinity of the city gate, he saw Pan Decheng and them, today came to the underground demon city with people from the Wuji Sect, people from the Bright Sect, people from the Tianshan Sect, people from the Jiuzun Sect and other super forces, the nine super forces all have elders with the younger generation of disciples to arrive, for these people, Chu Chen will not let go today, can he get out alive, if he doesn't want them to get out alive, even if they have a great creation, they will rest out.

After everyone entered the underground demon city, Chu Chen pinched his hands and used the power of the formation in the city to slowly close the city gate, when everyone reacted, they could no longer stop the city gate from closing, as soon as the city gate was closed, everyone couldn't help but be shocked, because the gate of this underground demon city had never been closed, this pass, I was only afraid of more than lucky!
