Zhou Chen returned to his courtyard, roasted some meat, and paddled his stomach, although he didn't need to eat every day now, but his empty stomach always made him uncomfortable.

"Hey, I still miss the time when I was in the Ten Thousand Beasts Mountain Range, fighting demon beasts with Liu Dahai and them, roasting meat, bragging, and being free, it's really good."

Zhou Chen ate barbecue and couldn't help but think of the experience of the three of them with Liu Dahai in the Ten Thousand Beasts Mountain Range in those days.

"Teacher, I'm suddenly starting to understand you."

"The sect is too comfortable, it is not suitable for the cultivation of the strong, the real strong are all experienced, such as me, I have never been idle in one place, you kid must make plans early and go out of your own way." Lie Tianzun floated out from the Mixed Yuan Bead and said.

"When I come out of the Purgatory Tower, I plan to go back to Qingyang City first, and if I don't finish all those families, I won't be able to set off with peace of mind." Zhou Chen frowned, remembering the current situation of the Zhou family.

"I'm afraid it's a bit difficult for you to be alone. I don't know about those families, but I think you're really weak. Lie Tianzun said.

"I know, I'm not going to do it." Zhou Chen said with a straight face, he had to think of a way, it would definitely not work to be straightforward.

Zhou Chen released the Black Flame Tiger, the Black Flame Tiger has grown stronger and stronger in the past few days, and it is the size of two Zhou Chen, and now Zhou Chen can ride him to play.

"The growth speed of this Black Flame Tiger is really a bit fast, it should belong to the second-order early stage demon beast at this time, it is about the first to third level of the human innate realm, and it is also a mutated demon beast, what will change in the future is not clear."

"It's good to grow up quickly, and you will cover me in the future." Zhou Chen touched Hei Yanhu's head with a smile, Hei Yanhu seemed to be able to understand Zhou Chen's words, squinted, grinned, and rubbed on Zhou Chen's body affectionately.

After eating and drinking enough, and teasing the Black Flame Tiger for a while, Zhou Chen returned to the cultivation room on the second floor, and took out the rubbing stone of the Nine Turns Xuanguang Step from the Ring of Na Ring, and the Seven Turns Thunder Dragon was still unable to cultivate, and he had to find a place where the thunder gathered.

"Your mind enters the Mixed Yuan Bead, try the martial arts in it, last time you comprehended the sword intent in it, the deity suspects that this Mixed Yuan Bead has the effect of improving comprehension, we don't know enough about the Mixed Yuan Bead, we need to try more and develop its function." Lie Tianzun reminded Zhou Chendao.

When Zhou Chen heard this, he felt that Lie Tianzun's words were very reasonable, and even if his mind entered the Mixed Yuan Bead, he pinched it in his hand, and the rubbing stone shattered, and a ray of white light did not enter the heart of Zhou Chen's eyebrows, which was the mental method of the Nine Turns Xuanguang Step.

Zhou Chen closed his eyes and began to comprehend, and his spiritual power followed the guidance of the mental method, wandering in the meridians.

Nine turns of Xuanguang step, divided into three stages: small success, large success, and consummation, each stage has a different degree of improvement in speed.

"These nine turns of Xuanguang step with my black robe, it's like an assassin, even if you can't beat it, you can still run."

Zhou Chen was delighted, this nine-turn Xuanguang step was very practical, whether it was killing the enemy or escaping, it was a great improvement, and with his hidden black robe, the sense of security was bursting.

Two hours later, Zhou Chen woke up with a slight smile on the corner of his mouth.

"Teacher, as you expected, I feel that I have a very strong sense of perception in the Mixed Yuan Bead, and the trajectory of the veins recorded in these cheats is clear, and it is easy to engrave it in my mind, it has only been less than two hours, and I have already practiced to a small extent."

Zhou Chen was very happy, it took less than half a day for the Nine Turns Xuanguang Step to reach the hand, and he practiced to a small level, who would believe it.

"Today, you have a good rest and adjust your condition, I guess this Purgatory Tower is not so simple." Lie Tianzun said.

"Well, I know, it should be pretty ruthless when you hear that name."

…

The next day, after Zhou Chen tidied up, he came to the square at the entrance of the Purgatory Tower early, the Purgatory Tower was still closed, and Zhou Chen had to wait and see in the square first.

On the square stood a huge red tower, hundreds of feet high, with a huge black iron gate standing in the center, with two terrifying monster heads on the door, a knocker as thick as a hand in its mouth, and an iron chain with a thick bowl mouth wrapped around it.

"Haven't you turned it on yet?" Zhou Chen muttered.

There were a lot of people coming to the square one after another, all of them were disciples of the Foundation Building Realm, and these were all people who were about to enter the Purgatory Tower to cultivate.

Zhou Chen learned from their chat that this Purgatory Tower was only open for fifteen days a month, and Zhou Chen came just in time today, it was the first day of opening the tower this month, so it was really better to come early than to come sooner.

Zhou Chen didn't know anything about the Purgatory Tower, he thought it was just a place to go in and cultivate quietly, but he learned from those disciples that the cultivation of this Purgatory Tower was actually a battle, an endless battle, provided that you had enough contribution points.

The Purgatory Tower was only open to Foundation Building Realm disciples, because it had little effect on the cultivation of Cave Heaven Realm cultivators.

The Purgatory Tower is divided into six layers, corresponding to the realm of the foundation building realm, the first floor corresponds to the early stage of the foundation building realm, the second floor corresponds to the middle stage of the foundation building realm, and so on, and the highest layer corresponds to the great consummation of the foundation building realm.

Thundered! Kela ......

The door of the Purgatory Tower made a loud noise, the iron chain as thick as the mouth of the bowl was removed, and the pitch-black door slowly opened.

"Stop and wait for the field to be cleared before entering the tower." One of the elders said, and then, ten elders leaped into the tower at a rapid pace.

"Clearance? Clear what? Zhou Chen asked suspiciously.

"There is a strange existence in this Purgatory Tower, called spirit monsters, they are formed by the Purgatory Tower through the condensation of spiritual power, which is the instinct of the Purgatory Tower, so this kind of spirit monster will be produced uninterruptedly, after killing this kind of spirit monster, it will directly turn into a spiritual power to be absorbed, this spiritual power does not need to be transformed, it can be used directly. If you don't enter the tower for a long time, a huge number of spirit monsters will accumulate inside, and it will be dangerous for disciples to enter, so the elders will clear the field first, and then the elders will open the formation of the cultivation room, but this formation can only last for half a month, and it will take another half a month to open it. A man with a handsome face explained to Zhou Chen.

"What do you call this senior brother?" Zhou Chen asked.

"Broken Monument Mountain, I am the elder brother of Broken Water Flow, my brother mentioned you to me, you are Zhou Chen, right? He said that you will definitely come when the Purgatory Tower is open, and you are the only one in the entire square who has not entered the foundation realm, so I guess it is you. ”

Zhou Chen nodded, arched his hand to Broken Monument Mountain as a greeting, and said, "Senior Brother Broken, this is such a mess, how should everyone cultivate?" Do you want to rob monsters and kill them? ”

"Naturally not, after entering the tower, choose the number of layers according to your own strength, there are many cultivation rooms on each floor, after choosing a cultivation room, put the token into the groove in the room, the cultivation room can automatically refresh the spirit monsters, these spirit monsters are not weak, the realm corresponds to the height of the tower, as long as you have enough contribution value of the token, you can always kill, the strength is strong enough and you can also adjust the number of each refresh, with your strength you can only go to the first layer to cultivate, the first layer will consume one hundred contribution points every hour."

Not only Zhou Chen, but even Lie Tianzun was surprised by this method, this cultivation method is indeed very fast, and the faster it kills, the faster it is refreshed, the faster the cultivation will naturally be, so the cultivation speed in the Purgatory Tower is different for everyone, and the most important thing is that these spiritual powers do not need to be transformed, which is equivalent to being able to stand there and recover while fighting.

Zhou Chen was a little looking forward to this Purgatory Tower, and he must at least break through the Foundation Building Realm before coming out.

After half a pillar of incense...

"After the clean-up, all disciples can enter the tower in an orderly manner." The elder appeared at the entrance and said.

Zhou Chen bowed his hand to the Broken Monument Mountain, said hello, and followed the other disciples and walked towards the Purgatory Tower.

At this moment, a lot of people gathered in the square, and everyone walked towards the Purgatory Tower with great anticipation.
