This is a closed underground stone chamber, rectangular, with an area of no more than seven or eight zhang, and the roof of the chamber is a huge pearl, emitting a faint light, illuminating the center of the room.

Jiang Chen's eyes were slightly closed, sitting in the center of the stone room, the demonic energy around his body was surging, and his handsome face was looming in the demonic qi, he breathed for a long time, and when the demonic energy around his body receded, he slowly opened his eyes, raised his hand and played a set of spells, and then, a stream of pure magic suddenly popped out from his fingertips, shooting towards the stone wall opposite.

With Jiang Chen's movements, Meng Changfeng, who was nested in the corner, moved, and she raised her eyes to look at the stone wall.

On the stone wall is a huge array, the content is mysterious, the lines are complicated, Meng Changfeng just glanced at it, and he felt dizzy and almost fainted.

It's been four years, and in the past four years, Jiang Chen has already caught Zuo Bufan and Jiang Yuzhou.

Jiang Chen absorbed Zuo Bufan's magic power in the same way, but he didn't move Jiang Yuzhou, who was now trapped in another corner like her.

Meng Changfeng didn't know what Jiang Chen was going to do with her and Jiang Yuzhou's lives, but as time passed, she became more and more afraid, Jiang Chen's appearance seemed to be opening some secret land, and keeping them would never be to take them into the secret place to hunt for treasures...... Once the secret realm is opened...... The fate of her and Jiang Yuzhou, I am afraid that it is better to be sucked dry of spiritual power, but looking at the current situation, Jiang Chen's goal is about to be achieved.

Jiang Chen turned his magic power into a formation knife and carefully landed on the formation map, he was engrossed, his eyes were staring at the stone wall with a good look, and his arm was as steady as a rock, continuously outputting magic power.

Four years ago, after the death of the Night Owl Demon Lord, Jiang Chen found the Yin Yang Banner from his storage bag, and within half a month, the image on the Yin Yang Banner changed again, the original map disappeared, and a complex and abnormal array appeared.

Seeing this formation diagram, the Night Demon Lord was extremely happy: "Only when the ten hall beads are collected, the formation diagram will appear, and we can finally start the next step of the plan!"

According to the instructions of the formation map, Jiang Chen found this stone room, this stone room is the only way to enter the central altar, and it is also the key to opening the central altar, as long as the formation map is completed on the stone wall, the central altar will be opened.

Although there are yin and yang flags to provide the formation map, but this project is not simple, this stone wall does not know what material it is, it is hard and abnormal, and when carving, the thickness and strength of the lines have strict standards, and there can be no sloppiness.

Jiang Chen prepared for nearly a year before he began to engrave, and it took three years to basically complete the carving of the array diagram, and now there are only a few strokes left, even if it is done.

The line engraved now, although it is only a short ruler long, but Jiang Chen also spent nearly half a day, he only has one chance, once there is a mistake, it will be a waste of all the previous efforts!

Seeing the brilliance flashing on the lines, Jiang Chen withdrew his magic power and slowly lowered his arm, even if he was a monk, for half a day, he could not move his arm like this, he was still a little unbearable, Jiang Chen rubbed his stiff arm slightly, closed his eyes and slowly breathed.

Since he absorbed the power of the Night Owl Demon Lord, his strength has increased greatly, and with the cooperation of Nan Lao, he has caught Zuo Bufan again, and now he is a cultivator in the middle of the Yuan Infant, and in half a month, the formation map can be completely completed, and the long-awaited time is coming!

Xiao Yin searched carefully among the ten Demon God Temples, and in his hands, there was only the Gonggong Palace

and the temple beads of the Kuafu Palace, the other eight should be in Jiang Chen's hands.

Jiang Chen, he must be hiding somewhere in these ten sacrificial halls, but he has carefully searched for it no less than ten times, but he still hasn't found it, where will he hide? Xiao Yin frowned, carefully deduced the location of the ten demon god halls, and turned around and walked towards the Chiyou Sacrifice Hall.

Chi You is the master of the army, and the head of the ten demon gods, his sacrificial hall is taller and majestic than other sacrificial halls, Xiao Yin used his divine sense to carefully explore the entire main hall inch by inch, including the surroundings of the main hall, and there is still no new discovery.

Xiao Yin's eyes were implicated, and he walked into the main hall, facing the temple door, the sculpture of Chi You stood on the high platform, with wings on his back, his eyes glared angrily, and the majesty in his eyes loomed, and he had a great sense of oppression, Xiao Yin put the statue up and down, carefully probed, and finally, his eyes fell on Chi You's eyes.

Where Chi You's eyes are looking...... Xiao Yin followed Chi You's gaze and saw that it was an incense burner at the entrance of the hall.

Could it be that there is some mystery in the incense burner? Xiao Yin's divine sense reached out again and searched carefully.

The material of the incense burner is very special, Xiao Yin has never seen it, the incense burner is carved with complex patterns, although there is no incense for tens of thousands of years, but there is still a lot of incense ash in it, it looks normal......

Xiao Yin probed for a long time, still found nothing, thought for a moment, suddenly took out a handful of incense candles from the storage bag, lit them, bowed a few times to the Chiyou Palace, inserted the incense candle into the incense burner, and as the incense rose, Chiyou's eyebrows suddenly emitted a very fine spiritual light, shooting on the pattern on the front of the incense burner.

After a while, the aura suddenly disappeared, Xiao Yin took a step forward, stared at the pattern, a touch of aura crossed the pattern, and there was a slight sound of the machine, and the incense burner "banged", divided into two halves, and opened to both sides, revealing a half-zhang square hole, with smooth steps at the entrance of the hole, extending into the darkness.

In the stone room, the array on the stone wall has faintly flowed with brilliance, Jiang Chen raised his hand, and continuously transported the spiritual power from his fingertips, it has reached the last moment, success or failure in this move, and he has seen a slight sweat on his forehead.

At this moment, there was a sudden movement outside the stone room, and someone had discovered it!

In the dim corner, Nan Lao's figure suddenly loomed, he glanced at Jiang Chen, who was engrossed, and quickly swept towards the outside of the stone room!

Xiao Yin walked down the steps of the cave, but after walking more than a dozen steps, he felt that a fierce palm wind was coming, and he hurriedly swung his sword, and his body had retreated rapidly!

Before Xiao Yin could stand firm, there were already golden palm prints in all directions, and they all slapped down on Xiao Yin, Xiao Yin's figure hurriedly rose up, but unexpectedly, a huge golden palm print suddenly appeared above his head and pressed down on him!

The long sword in Xiao Yin's hand made a soft "hum" sound, like a long rainbow piercing the sun, and slashed towards the sky palm print!

The moment the sword and the palm print got along, a brilliant aura like fireworks erupted, but the palm print only trembled, but it did not disappear, and continued to press down!

At this critical moment, Xiao Yin's face remained unchanged, his eyes drooped slightly, his horizontal sword was in his chest, he pointed at the sword body, recited the mantra silently in his heart, and suddenly turned around and waved!

This sword seemed to be light and fluttering, but the moment it was swung, there were thousands of sword rays, with flames that burned everything, roaring towards the surrounding palm prints.

The surrounding palm prints seemed to melt and disappeared one after another, and at the entrance of the cave, Nan Lao slowly walked out

Come, the hand behind him trembled faintly, and his Tianluo palm was actually cracked by Xiao Yin!

Xiao Yin held the sword in front of him with both hands, and looked at Nan Lao vigilantly, this is Jiang Chen's person, Jiang Chen should be underground!

"You can dissolve the old man's Tianluo palm, it's really amazing!" Nan Lao stood in front of the entrance of the cave, his eyes were like an eagle, staring at Xiao Yin: "However, if you want to enter the cave, it depends on whether you have the ability!"

After finishing speaking, his left hand suddenly poked out, and he slapped at Xiao Yin, who hurriedly raised his sword to block!

I only heard a crisp sound of "!", and the sword light slashed on Nan Lao's left arm, not only did it not cut off his arm, but the junction between the sword and the arm actually erupted into a burst of sparks!

This is a phenomenon that only happens when metals collide!

Xiao Yin changed color slightly, but Nan Lao smiled weirdly, only to see his left hand flipped violently, and grabbed Xiao Yin's long sword!

Xiao Yin hurriedly put away his sword and retreated, but Nan Lao's body did not move, but his left arm suddenly stretched out, chasing Xiao Yin away!

This arm is completely different from a normal person, the whole body is golden, there is no flesh and blood, and it glows with a cold light!

No wonder he hasn't sacrificed his magic weapon, it turns out that his magic weapon is actually an arm! Xiao Yin's expression was solemn, and the long sword in his hand avoided this arm and beckoned straight to him!

With the strength of the late Yuan Infant, Nan Lao fought against Xiao Yin of Jindan Da Quan, even if Xiao Yin was strong, Nan Lao would not be defeated, his purpose was just to entangle Xiao Yin and buy time for Jiang Chen, as for Xiao Yin, he didn't know what arrangements Jiang Chen had, so he didn't make a dead hand for a while.

After fighting for more than ten rounds, Xiao Yin also sensed that Nan Lao was delaying time, what was Jiang Chen doing underground? Xiao Yin was faintly uneasy, so he simply sacrificed the Yinri Sword and slashed it hard!

Nan Lao was defenseless for a while, and was slashed by the Yinri Sword, and his left arm suddenly emitted a burst of light, and it suddenly retracted back to its original state!

Xiao Yin had already taken this opportunity to sweep towards the cave in the ground! Nan Lao hurriedly chased after him!

As soon as Xiao Yin's footsteps stepped on the steps in the cave, the sky shook for a while!

Nan Lao's face was suddenly happy: Childe succeeded! He no longer pursued Xiao Yin, only covered his sour left arm, and followed him into the cave.

Jiang Chen looked at the stone wall in front of him that suddenly shone brightly, and finally showed a smile on his face.

With the completion of the formation, the stone room where he was located has undergone earth-shaking changes, with gold bricks paving the floor, carved beams and paintings, and the treasure light on the wall looming, illuminating the entire cave room brightly and abnormally!

The sudden light made Meng Changfeng and Jiang Yuzhou shrink at the same time, eager to shrink themselves into the wall.

"Hahahaha! It's done!" the Night Lord laughed madly!

Jiang Chen glanced around, a little puzzled: "Is this the central altar you said?"

"Naturally not! You still need to use the temple beads, have you seen those nodes in the formation diagram that emit green light? As long as you put the temple beads into those nodes in turn, the center altar will appear!"

The Night Demon Lord was in a good mood, and said two more words: "As for how to put it, just look at the instructions on the yin and yang flags." ”

Jiang Chen had already taken out the Yin Yang Flag, looked at it for a while, and then took out the temple beads again, and said: "There are only eight here, and there is still a lack of ...... from the Chiyou Hall and the Gonggong Palace."

"Hahaha! It's okay! You just need to put these eight in there, and the remaining two will naturally be summoned!"
