The city garrison dispatched all the staff, searching everywhere for clues, and finally found the underground. Until this time, everyone discovered that all the creatures living in underground ditches and being played by them had disappeared.

This was definitely a major incident, and the City Guard quickly sent the news to Audrey's case.

Without saying a word, Audrey drew more than a thousand city defense troops and started searching from all the ditches where clues were found.

Then, the day after the city defense force was dispatched, some searched ditches collapsed and blocked the channels.

This was obviously something that someone deliberately collapsed, and the other party wanted to cover up the secrets underground. This time, even Fulisuo began to pay attention.

A total of 5,000 city defense forces were dispatched to try to enter the underground from various channels to find out the other party's secrets. However, the underground channels were too complex and huge. Thousands of city defense forces were scattered, but the effect was not obvious. Today, this one was dug through, and less than a few hundred meters away, the channel in front collapsed again.

The army had even entered the ditches. In order to prevent the other party from continuing to destroy, the soldiers were directly stationed in the digging channel, but early the next morning, the rear of the channel collapsed again, blocking the garrisoned soldiers in the channel.

After a while, the army began to dare not go deeper, fearing that it would be buried inside.

Audrey's current location was when she collapsed last night, and a team of fifty people was trapped inside. If she could not dig through the collapsed place as soon as possible, the sergeants inside were likely to be suffocated due to the lack of air.

Faced with this situation, Audrey was a little helpless. The other party did not need to confront you head-on. As long as you kept digging down the channels, you could not advance or retreat. There were only tens of thousands of city defense troops, but they could not use their number advantages. If this continued, the five thousand soldiers sent would soon lose their morale.

But after evacuating like this, Audrey was unwilling to give up. Those enemies who had not yet appeared did not know what secret activities were being carried out under the ground. They could not finish talking about it and would endanger the safety of the entire Black Iron City. If the other party was not found, Audrey would not be at ease. She didn't want to sleep in the city lord's mansion one day, and suddenly a bunch of assassins rushed out.

"What should I do?" Audrey asked Fulisuo in a low voice.

After all, Audrey is still too young. When she encounters such an unspoken enemy, she can't think of any effective way.

"There is no use for too many people, and the other party will not show their faces. We form an elite team, find four or five earth-class magicians to open the way, bring all teleportation scrolls, and kill directly in. They are doing this to destroy it, and we must want to hide some secrets. We don't need to care about how the other party destroys it. As long as we find the place where the secret is, these people will definitely show their faces." Fulisuo said coldly. Only by taking the initiative to attack and hit the opponent's key points can they be forced out.

"Okay!" Audrey's eyes lit up. She liked this idea. As a great swordsman, she is a well-deserved attacker. She is definitely indispensable for such actions.

Audrey made a quick decision and rushed out of the ditch a few times and went to gather people in person.

...

In the underground cave, the buried altar gradually revealed its original appearance with the hard work of hundreds or thousands of undead creatures day and night. This is a circular altar, divided into three layers, the diameter of the bottom layer is more than 100 meters, and the diameter of the upper layer is only twenty meters. There are steps leading to the highest level in the east, west, south and north directions, and the steps are opposite each other, dividing the circular altar into four equal parts.

But even if you find it, it doesn’t matter. Important locations of the altar have been dug up. Although there is a large area covered with soil on the third floor, the first and second floors have been basically cleaned, which means that the altar can operate forcibly.

As long as the altar can operate successfully, the powerful tearing force released can instantly clear all attachments, and then form a dislocation space at the third level. At this time, it doesn't matter even if the entire cave collapses. The force field generated by the dislocation space will directly send all objects falling on the altar to another plane.
