The mine is located in the south of the central part of Jimo Mansion. It was originally a small garden with various flowers and plants planted. However, in order to mine the dark stone veins, a loft was built there to cover up the eyes.

Ji Yunlang was standing outside the attic gate at this moment. When he arrived here, the black gas that could be seen in the naked eye was swaying. It seemed that this side was really as Jimo Kongyun said, and it was the place of the mine cave.

After hesitating for a moment, Ji Yunlang pushed open the wooden door and entered the attic with a firm step. No matter what problems Jimo Kongyun had, the most important thing at the moment was the monster.

In the attic, the extremely exquisite interior has been infected by the demonic energy and is a little black and decayed. After passing the decorations, Ji Yunlang quickly walked inward and saw a large black tiles on the ground in the middle of the attic. This is the entrance to the mine.

Ji Yunlang stopped and took out three red-colored array flags with colorful patterns from the storage bag, then placed them one by one, and yelled in a low voice: "Start!"

Silently, a small magic array was formed. The function of this magic array was to trap the demonic energy in the attic and prevent it from leaking and affecting other mortal cultivators in Jimo City.

After doing all this, Ji Yunlang pried open the floor tiles under his feet.

At that moment, waves of black gas surged out from the dark hole, but due to the obstruction of the magic circle, they could not leave the place, so they gathered together and condensed into a giant skeleton that was ten feet tall.

Runes were everywhere on the skeleton's body, and its upper and lower jaws trembled slightly, and a hoarse voice came out.

"You are so brave that you want to block Ye Ye's way."

Ji Yunlang snorted coldly, without saying a word, and with a casual move, the magic array surrounding the entire attic suddenly moved, and several red chains condensed in an instant. With the sound of "Chengcheng", it rushed towards the skeleton.

The skeleton had no intention of resisting. He looked down at the chains, smiled, and turned into a ball of black gas and disappeared.

"Ghosts and monsters." Ji Yunlang murmured, and with a urging technique with both hands, the effectiveness of the magic circle was maximized, and then he jumped into the mine.

The mine is very large, not straight downward, but has a certain inclination. The ground here has been reinforced by people from Jimo family before, and steps have been dug in some extremely steep places, so it is much more convenient to enter and exit the mine.

Ji Yunlang walked down for about half a quarter of an hour and saw an extremely wide cave. There were many beds here, which looked like a place for miners to rest. In addition, there were some furnaces for processing Kong Xuanshi. After all, there were a lot of impurities for mining Kong Xuanshi. Only by processing it can you meet the market standards and save space in the storage bag.

After wandering around the cave, there was nothing special except for the demonic energy.

Ji Yunlang turned his gaze to several mines around the cave. According to the information obtained from Jimo Kongyun, the Kongxuan stone veins were very large, and it was calculated that it was about twice that of Jimo Mansion. At that time, it was not mined, but about half of them were mined.

The remaining mineral veins are of the best quality. If they are used to make storage bags, the space will be several times larger than that of ordinary storage bags.

Of course, Jimo Kongyun dared not make any more ideas about that place. After all, the monsters came out from there before. If it weren't for the ban, his Jimo family would have been completely finished.

Following the route pointed out by the map, Ji Yunlang chose a mine cave and walked inward. After walking for about a quarter of an hour, there was no road ahead of him.

Looking at the section of irregular hollow stones and various stones in front of him, Ji Yunlang turned his head and pondered for a moment, and then took out the wooden hammer.

This wooden hammer is a blood vessel. As for why it appeared in the ore veins and was finally obtained by Jimo Kongmei, we have to ask the elder in the sect who was in seclusion.

The wooden hammer was suspended on the palm of Ji Yunlang's palm. As the magic tricks continued to penetrate, the surface of the light gradually shone, and it seemed to have some connection with the cross section in front of him. The latter was slightly shocked, and a portal condensed after a few breaths.

Ji Yunlang took the wooden hammer, summoned the green clouds and stepped into it.

Behind the portal is a small space. There is a light golden ball in the center of it. The surface of the ball is uneven. Looking closely, countless runes are spread all over it, and light golden ripples emerge from it. After a leisurely turn, they run towards the endless places below.

"The center of the magic circle." Ji Yunlang murmured. Compared with this, the magic circle he had previously arranged in the attic in the courtyard was not worth mentioning at all.

A powerful magic array not only needs to have a magic array center like a ball in front of you, but also requires some powerful magic weapon as a means of defense and attack. In addition, a massive amount of spiritual power is also needed as a supply of magic array power.

Among these things, the production of the magic array center is the most difficult. It not only requires adjusting the power of all aspects to make the magic array generally balanced, but also requires extremely strong manipulation to facilitate the owner of the magic array to control the operation of the entire magic array.

In addition to these two factors, the center of the magic array in front of us also has a certain degree of autonomy. In the face of various complex situations, we can make independent judgments and react.

Ji Yunlang speculated that when the monster was about to break out of the seal, the center of the magic array made an independent judgment, believing that with his own strength, he could not stop the leakage of demonic energy, so he sent the blood magic weapon out, allowing Jimo Kongmei to play a certain role to prevent the spread of demonic energy.

As for the ban that severely damaged the monster in the end, it should be the attack method of the magic circle. What exactly is it, the elders of the sect have not explained in detail.

What Ji Yunlang needs to do at this time is to repair this giant magic array so that its power will be restored as before, so that the monsters cannot break the seal.

This is just the first step, and the second step is a bit dangerous. He needs to go deep into the underground palace and use a special method to trap the monsters and make them sleepless. This is how to successfully complete the tasks assigned by the elder.

According to the steps taught by the elders of the sect, Ji Yunlang took out pieces of spirit stones from the storage bag, placed them in a special direction, and then slowly pinched the trick.

The center of the light golden magic array trembled slightly, and countless runes on its surface leaped out, condensed into spiritual runes, and then attached to the spirit stone.

As time passes slowly, the spiritual power contained in the spirit stone is sucked away by the runes. It can be seen that the spiritual light on the center of the magic array becomes brighter, and the power of the ripples released from it is also a little stronger than before.

But Ji Yunlang could still show some difference from it, and then looked at the empty space around him and suddenly realized.

It turned out that the elders of the sect drew some special force from the Kongxuan stone, which made the magic circle operate normally. However, due to the later mining of the Kongxuan stone mineral veins by the Jimo family, the power to maintain the operation of the magic circle was weakened, which gave the monster the opportunity to break free from the magic circle. Although they finally trapped the monster seriously, the magic circle inevitably suffered some damage.

Ji Yunlang couldn't help but sigh at the great work of the elders of the sect.

Then he began to feel distressed about the spirit stones. According to the elders, the number of spirit stones needed to repair the magic array was very large. Fortunately, he had saved a lot before, so he was able to avoid selling some spiritual objects in exchange for spirit stones.

Then he thought again, with the points he had promised to compensate him, this trip was considered profitable.

Plus the hollow black stone in the storage bag...
