After leaving, Lu Changjing suddenly realized one thing, that is, when he appeared at the edge of the Tianzhong area before, there were not only one but two warnings of danger perception. One was naturally the Judge Xuan Gui outside the Tianhen, and the danger warning was not high. Then there was the second danger warning, which followed the first danger warning, and it should not come from the Judge Xuan Gui. After Lu Changjing endured the attack of the Judge Xuan Gui and successfully escaped thousands of miles away, the first danger warning brought by the Judge Xuan Gui disappeared, but the second danger warning was still there. At that time, Lu Changjing mistakenly thought that it was still from outside the Tianhen, but now think about it carefully, if it really came from outside the Tianhen, there would not be two danger warnings. He had already left the Tianhen too far, and the world-destroying monsters outside could no longer bring danger warnings, so where did this danger warning come from? There was something wrong with the Tianzhong area. At this critical moment, since Lu Changjing found something wrong, he would naturally not let it go easily. That's why he turned back and spent a precious Xuan-level talisman, the Heaven-hiding Talisman, to hide himself with the Heaven-illusion Tribulation and sneak into the Tianzhong area quietly. This Heaven-hiding Talisman was obtained from Jiuying, and Jiuying's Heaven-hiding Talisman was given by the world-destroying demons and monsters outside. Now it can be regarded as a return of favor. In the land of Jiuzhou, Xuan-level talismans are extremely rare, with only dozens of them. This is what Lu Changjing obtained by plundering the entire land of Jiuzhou. Many of them came from Jiuying, that is, the demons and monsters outside.
With the main method of hiding, the Heaven-hiding Talisman and the Heaven-illusion Tribulation cooperated, and he successfully sneaked into the Tianzhong area, and was not discovered by the world-destroying demons and monsters outside Tianhen. As soon as he arrived in this area, the danger perception played a role again and began to warn. However, this warning was not high. Even if the danger really broke out, he would only be injured at most, and his life should not be in danger. With his current defense and various characteristics, it would be difficult for him to get hurt. The power of his soul fluctuated, quietly exploring the situation, trying to find the source of the danger warning and see what was going on. During this period, he deliberately observed Ao Lie and found that he was patrolling the periphery of the Tianzhong area with a group of gods and demons, and there seemed to be nothing unusual. However, because they were in the air under the sky mark, the world-destroying monsters outside could see them clearly, and Lu Changjing was also worried, so he did not approach them and used the soul-stealing technique to check the situation. He deliberately used the connection between the soul-picking technique and the soul-capturing technique to perceive, but did not find anything unusual. With a slight frown on his brows, Lu Changjing continued to search in the Tianzhong area, and through the warning of danger perception, he approached its source little by little until he came to the place where the danger warning was the strongest. This is a node where the ground veins converge in the Tianzhong area. Although it has been severely damaged, it has not been completely destroyed. At this moment, in the node where the earth veins converge, there is a fist-sized purple-black bead floating. From it, Lu Changjing sensed a danger warning far beyond other places. Mysterious Thunder Bead! A disposable mysterious weapon, it is a low-level mysterious weapon refined by Xuanzun using the Nine Heavens Thunder. It is similar to the Thunderbolt, but its power is tens of millions times more terrifying than the Thunderbolt. Once it explodes, it can turn a hundred miles into powder. Especially this Mysterious Thunder Bead is located at the node where the earth veins converge. After detonation, it can drive the surrounding earth veins to explode together. At that time, the amazing power can even bring some danger to Lu Changjing. His face changed, and Lu Changjing did not dare to move this Mysterious Thunder Bead, because it was surrounded by the imperceptible power of the soul. Once it was found to be passive, it was estimated that the other party would immediately detonate the Mysterious Thunder Bead. At that time, the earth veins in this area would be severely damaged, and the Jiuzhou barrier would also be greatly weakened. He left silently and rushed to other places, heading to the important veins in the Tianzhong area where they converged. As expected, he found several more black thunder beads in these places. If these black thunder beads were detonated together, the earth veins, water veins and spirit veins in the Tianzhong area would be completely destroyed, and the power of these earth veins, water veins and spirit veins could be mobilized to impact the Jiuzhou barrier again. As long as the world-destroying monsters outside cooperate properly, they might be able to directly break the Tianhen and let the monsters outside enter.
It turned out that the real danger warning came from here. When these several black thunder beads exploded and detonated the remaining earth veins, water veins and spirit veins in this area, even with Lu Changjing's defense, there was a certain risk of life. The power of the disposable mysterious weapon, combined with all the remaining veins in the Tianzhong area, and the world-destroying monsters outside the Tianhen, even Lu Changjing could not bear it. Unless you activate the Vajra Indestructible Characteristics, Nine Dragon Cover, Nine Dragon Armor, Nine Dragon Bell, and Body Protection Mysterious Talisman at the first time... Otherwise, if you are a little slower, you may be seriously injured and your life is in danger. The warning of the danger perception is not wrong. This Tianzhong area has indeed become dangerous. But are these Mysterious Thunder Beads arranged by the world-destroying monsters and demons outside through special means, or are they arranged by an insider? Lu Changjing frowned, thought about it, quietly left this place, and rushed towards the nearby Qianmenzhou City. Qianmenzhou City is also a place where veins converge, and its status is not much inferior to that of the Tianzhong area. If there is an insider, this area will definitely not be spared. Soon he arrived at Qianmenzhou City and dived directly into the depths of the ground, and then Lu Changjing's danger perception began to warn again. Following the reminder of danger perception, Lu Changjing found several more black thunder beads, all of which were covered by black talismans. If the characteristics of danger perception were not too powerful, even Lu Changjing would not be able to find these hidden black thunder beads. There is an insider, and it is not an ordinary insider, otherwise it is absolutely impossible to arrange the black thunder beads deep in the Qianmenzhou City, and they are also important nodes where the veins converge. And this insider must be a god or demon in Qianmenzhou, because the arrangement of these black thunder beads requires their cooperation. Lu Changjing's face became extremely ugly. He has been busy with retreat cultivation in recent years. Almost all the things were handed over to the soul-picking slaves and the nine dragon slaves. He thought they would not have any problems, but he did not expect that such a big mistake would happen. If he let things develop without knowing anything, when the enemy triggers the black thunder beads, the veins of the entire Jiuzhou land will be severely damaged, and the Jiuzhou barrier will be weakened to the extreme at that time. If the demons and monsters outside cooperate, they will most likely be able to directly break through the Jiuzhou barrier, and the entire Jiuzhou Alliance and the human race will face a catastrophe. This time may be within a few years. So he must solve this matter, otherwise the Jiuzhou land will be finished before he is promoted to the realm of Xuanzun. After a little consideration, Lu Changjing immediately rushed to Xuanwu Mountain. After confirming that there was no problem with the Fushan Divine Turtle, he asked it to quietly find hundreds of basalt stones from Xuanwu Mountain and cut them into simple containers with Xuan tools. The power of those Xuanlei beads was too terrifying, and he dared not take them away. Lu Changjing planned to use basalt stone containers to pack them up. At that time, even if these Xuanlei beads exploded, the power would only be limited to the containers made of basalt stones, and could not cause too much damage. At the same time, he left the power of the soul on these basalt stones as a warning, and when all the Xuanlei beads were found, they would be collected. Soon Lu Changjing returned to the Tianzhong area, put all the black thunder beads deep underground into basalt containers, and then went to Qianmenzhou City to put the black thunder beads there into basalt containers. After that, it was Bihuzhou City, Ashapis Mountain, Fengmingfu City... These were all important places where veins converged, and all of them were placed with one to nine black thunder beads, almost covering the entire Jiuzhou land, with more than 300 black thunder beads. A big deal, really a big deal, even Lu Changjing had to sigh. These are all Xuan weapons, even if they are disposable Xuan weapons, they are still Xuan weapons. To make a black thunder bead, a Xuan weapon master needs to take action, spend a lot of time and energy, and also need to be supplemented with various Xuan-level resources and treasures. One requires a lot of materials and time, not to mention more than 300. The world-destroying monsters outside, won’t take out all the black thunder beads they have stored? Unfortunately, it is surrounded by the power of the soul, which is most likely from the world-destroying monsters outside, and it cannot be recycled at all. If it can be collected for one's own use, it must be a very good trump card.
Sighing, after packing all the black thunder beads, Lu Changjing did not take them away, but used the soul-stealing technique in Qianmenzhou City to explore the memories of those soul-catching slaves to see if there are any problems. Even the soul-picking slaves were explored by Lu Changjing. Although the soul-picking technique is powerful, it is ultimately in the category of mysterious techniques. Lu Changjing's cultivation realm is only the realm of gods and demons, and there are many means to block and remove its effects. You must know that the enemies outside are mysterious monsters, whose cultivation realm far exceeds Lu Changjing, and the treasures and mysterious techniques they possess are also far beyond Lu Changjing. Before, he was able to get Jiuying out of his control, let alone now. But what made Lu Changjing helpless was that even though he used the soul-stealing technique to the extreme, he did not find any abnormality, as if there was no problem with these soul-picking slaves and soul-capturing slaves. But Lu Changjing was sure that without the cooperation of these gods and demons, the enemy would never be able to put the black thunder bead into the place where the veins converged under the Qianmenzhou City. Could it be that there was some powerful treasure that could hide this part of the memory? It was probably so. Before, the demons and monsters outside could take out treasures such as the Hidden Heaven Talisman and the Soul Washing Mirror, let alone now. Faced with this situation, Lu Changjing was also a little helpless. He couldn't take them all down. If this was the case, the movement would definitely be big, and the enemy would immediately realize that something was wrong. It was a pity that there was no powerful detection technique, but even if there was, facing this kind of mysterious means, with Lu Changjing's current cultivation in the realm of gods and demons, it would be a bit difficult to play a role. In the final analysis, it was still because of the insufficient cultivation realm. However, those world-destroying demons and monsters outside had deployed Xuan-level means, and even if Lu Changjing had Xuan arts and Xuan weapons, it was difficult to deal with them. In this case, let's spend a little effort to see if we can detect any abnormalities from other gods and demons. Lu Changjing began to look through the memories of many gods and demons in Qianmenzhou City to see if there were any abnormal gods and demons in their memories. However, the enemy was obviously quite careful. Even though Lu Changjing had looked through the memories of these gods and demons, he did not find any abnormalities. Or maybe the other party did not let other gods and demons know when they acted, and they hid it deeply and did not reveal any flaws. In this case, it seems that we can only use thunder and lightning means. Before this, Lu Changjing went to Baiyujing again on purpose, and did not find anything abnormal here, because Baiyujing did not have an important place where veins converged. Or in other words, the many earth veins, spirit veins, and water veins hidden deep underground were not discovered under the cover of the real Zhoutian Star Array. In fact, Baiyujing is the place where the veins of the eastern land converge, but it was covered by the real Zhoutian Star Array. Moreover, the eastern land was quite rich before, but it became barren because of the support of the real Zhoutian Star Array. It is precisely because of this that this place was not favored by those insiders, so the black thunder beads were arranged, but it is also possible that the other party has not arranged it here yet. Thinking of this, Lu Changjing did not act immediately, but went through the entire Jiuzhou land again to see if there were any undiscovered black thunder beads. After confirming that there were no omissions, Lu Changjing came to the Tianzhong area quietly, preparing to take out all the black thunder beads with the Tianzhong area as the center. He did not ask those soul-picking slaves and soul-capturing slaves to help, because Lu Changjing was worried about them. If something went wrong, the consequences would be disastrous. In the process, he will definitely be discovered by the world-destroying demons and monsters outside, and then he will definitely detonate these black thunder beads. It depends on whether Lu Changjing is faster or they react faster. Let's start! Lu Changjing went deep into the underground of Tianzhong area, and used the size of Ruyi to transform into a small man of several centimeters. He used the Nine Dragon Boots, Nine Dragon Steps, and Nine Dragon Mysterious Suit to the extreme. In an instant, he traveled all over Tianzhong area, took away all the black thunder beads, and then went straight to Ao Lie. He used the Nine Dragon Tribulation to control Ao Lie again, and at the same time used the Soul Capture Technique to control several gods and demons under his command.
