This person is also an amazing person, he entered the spiritual stage at the age of ten, and at the age of fifty, he has reached the realm of the spiritual stage, and after more than a hundred years, he directly promoted his cultivation to the spiritual stage.

Just as he reached the beginning of the spiritual period, by chance, he got a formation book from the ancient period, which was all-encompassing and difficult and obscure.

This person is also a master who does not admit defeat, and after some research, he found that the formation knows that it is boundless, so he began to study the formation.

In the following hundred years, he studied day and night, and finally studied the magic circle in the formation book roughly.

After he studied the texts, his reputation as a formation mage began to spread among the immortal cultivation world, which made him feel the pleasure of being respected, so he became more and more obsessed.

After another hundred years, this person has studied the entire classic, and at the same time, he has also become the most famous formation master within a radius of thousands of miles.

However, just when his formation reached an extremely high level, one day, he received an invitation letter to ask him to arrange a large formation.

At first, he didn't agree, but when the other party told him that it was an ancient array that had long been lost, his restless heart finally began to throb.

When he came here, he found that the difficulty of this large array was really only seen in his life, although he also realized that it would take a long time to set up the large array, but in the end, he couldn't help but be curious about the formation and stayed.

In this way, these hundreds of them have lived here for hundreds of years, and after the joint research of hundreds of top array mages, this magic circle has finally been arranged.

When they set up the circle, he realized that his lifespan was about to run out, and in order to break through before his lifespan was exhausted, he began to retreat in this cave.

It's a pity that until the last years, he couldn't break through the realm.

Seeing this, Lin Jiu was also moved, for a magic circle, it would take hundreds of people hundreds of years to study, what kind of magic circle this is, it was so complicated.

Unfortunately, the book does not record anything about the cave except for the life of the cave owner.

Lin Jiu read the classics and was disappointed in his heart, he didn't believe that there was no other way out here.

After a moment's hesitation, he strode into the relatively spacious cave and continued his search.

Time passed slowly in their constant search, and early on the fourth day, Lin Jiu came to the stone chamber again, and the inside was the same as before, no different.

The girl looked at Lin Jiu with a desperate expression, and her mood was extremely low.

"Are we really going to die here?" After so many days and nights of getting along, the girl's attitude towards Lin Jiu was no longer as indifferent as before, and she even regarded him as a friend.

"No, there must be a way to get out. Lin Jiu shook his head firmly.

"We've searched every part of the cave, and we've even been to the entrance dozens of times, but we still haven't found a place to go out. The girl said helplessly.

"Yes, every inch ......," Lin Jiu whispered.

"No, there is another place ......" Lin Jiu's mind suddenly flashed with a flash of inspiration, and he stood up with excitement on his face.

The girl was startled by his exaggerated movements, and looked at Lin Jiu with a puzzled expression, her eyes full of suspicion.

Lin Jiu ignored it, and entered the narrow passage with a shake of his body.

He doesn't know how many times he has walked this road in the past few days, and every inch of land is extremely familiar.

Without stopping along the way, I went straight to the front of the prison.

Although they had searched every inch of the cave before, this one was the only one that had not entered.

The prison is made of cold iron, and it is not easy to open it.

A flash of inspiration flashed in Lin Jiu's hand, and a spike appeared in his hand.

With all his spiritual power, he slashed down towards the gate.

A "ding......" sound sounded, and the chains opened.

Lin Jiu was overjoyed in his heart, and strode into the cell, the bones in the cell were lying in the center, and his body was firmly locked by the root chains, and the chains were covered with various runes, trapping the bones firmly.

Lin Jiu didn't touch the bones, but rummaged through the cell.

To his disappointment, however, there was nothing useful other than some strange patterns drawn on the ground.

"It seems that I have to disturb the seniors. Lin Jiu saluted the skeleton and said.

The skeleton had been dead for an unknown number of years, and there was no reaction to Lin Jiu's salute.

Lin Jiu ignored it, and with a flash of inspiration in his hand, he cut off those chains one by one.

Although these chains were wrapped in runes, they were only aimed at the skeleton, and had little defense against external attacks.

Next, Lin Jiu picked up the bones one by one and placed them on one side.

"Huh, what is this?" Suddenly, a white bone caught Lin Jiu's attention.

This bone is only the size of a thumb, and although I don't know how many years have passed, the bone is still crystal clear.

"Could it be that there is some mechanism in here?" Lin Jiu said secretly in his heart, and immediately probed over with a thought.

With the probing of the Divine Thoughts, a forbidden force actually directly bounced Lin Jiu's Divine Thoughts power away.

"Sure enough, there was a problem. The divine thought was bounced away by the white bone, Lin Jiu was not surprised or overjoyed, and immediately the divine thought moved, and the powerful divine thought rushed over.

Just like before, the power of his divine thoughts was bounced away as soon as it touched that white bone.

However, Lin Jiu didn't give up, and his divine thoughts continued to surge towards the white bone.

For a while, the divine thoughts and the rebound power on the white bones started a tug-of-war.

I don't know how long it took, Lin Jiu's divine thoughts finally broke through the last line of defense on the white bones with a pop, and directly entered the white bones.

It seems that although the prohibition on this white bone is powerful, after all, it is still the water without the origin of the wood, although it is powerful, it can't withstand Lin Jiu's constant attacks.

With the divine thought, he probed in, and a huge space immediately appeared in front of Lin Jiu's eyes.

"Is this a Qiankun bag?" Lin Jiu was startled, although he also had a Qiankun bag on his body, but in terms of the space inside, a Qiankun bag was not as good as the white bone in his hand.

With this discovery, Lin Jiu almost jumped up, and immediately searched quickly in the white bone space.

Not to mention, there are really a lot of things in this white bone space, in addition to a large number of spirit crystals, there are also a lot of spirit slips, and I don't know what these spirit slips record.

Seeing this, Lin Jiu immediately became excited, and immediately his mind moved, and a piece of spirit slip flew up and fell into his hand.

Lin Jiu's mind moved and probed into the spirit slip.

After some inspection, Lin Jiu found that this piece of spirit slip recorded some basic magic circle knowledge.

After reading the contents of the spirit slip roughly, Lin Jiu shook his head in disappointment, and then moved his mind again, and changed a piece of spirit slip to continue searching.

Like the previous piece of spirit slip, this piece of spirit slip also records some knowledge of the magic circle.

Next, Lin Jiu kept taking Lingjian out of the space to look at it.

It's a pity that after some inspection, I found that in addition to recording some formation knowledge, these spirit slips are some discussion of formation content, and they have no effect on how to leave this cave.
