Like the buildings on the ground, the underground palace of the White City is also divided into multiple levels, and in order to confuse the world, the first two floors of the underground palace of the White City are the underground water conservancy system and the warehouse storage area.

There will be some annoying little monsters here, and there will also be some mercenaries who will come here to clean up those little monsters.

But few people know that these little monsters are already different from the monsters in other places because they are affected by the demonic breath of the underground palace and the underground demon, but this influence is not too obvious, and the world often only thinks that these little monsters have too strong reproductive ability and are inexhaustible.

Now the underground seal may be opened at any time, affected by the underground demonic aura, the number of those little demonic beasts has also surged, and when Kunwu and his party came to the first floor of the underground palace, they encountered several waves of mercenary teams cleaning up the little demonic beasts.

However, because everyone disguised their identities and used the identity of the "Royal Clean-up Team", the mercenary team did not recognize that there were their Emperor Majesty and Duke Isidor in the team.

"The nezumi were originally a scavenging rat, but due to the influence of the demons of the underworld, they gradually mutated, and now they have a preliminary human form and a great increase in intelligence. Fortunately, their strength can still barely reach the apprentice level, and they cannibalism like the Underworld Demons can improve their strength! ”

On the way, Isidor explained to Kungo about the nezumi.

The nezumi is a humanoid monster that is only more than eighty centimeters tall and walks semi-upright. They have limbs similar to those of humans, but they have rat heads, and they are mainly scavengers, but they don't mind eating fresh meat when they encounter a living person.

The nezumi will destroy the sewer structure, and sometimes even follow the sewers to the surface to attack the living, and they will spread the plague, which is a famous cancer in the White City.

Every year, when the number of nezumi people skyrockets, a large number of mercenaries and even royal guards will enter the dungeon and start cleaning these things.

And every time the underground demon is about to be born, the number of rat people will be even more terrifying. And the desire to fight will be stronger.

When Kungo passed by those mercenary teams before, he heard them talk about the fact that some mercenary groups encountered thousands of nezumi, but only one member of the team of ten escaped alive.

"The cleanup of the nezumi is mainly handed over to these mercenaries, and some second-tier troops will also join in. They will only be active on the first two floors of the dungeon. The passage to the third floor is sealed, and there are several fake passages and false third floors to confuse the world! ”

Fifty years ago, when he first reached the fourth star, Isidor participated in an underworld crusade, and now this is the second time. But the Duke did not have any panic, only a solemn face.

"Why don't you just put the seal in and fill it up?" Kungo asked a question that sounded rather silly.

"It's useless. The Underworld is good at making holes, but it's useless to stop them by physical means. A generation of ancestors once tried to completely block that place with diamond and holy white copper juice, but the result was that it was easily dug through by the demons of the underworld! ”

Agette shook his head: "If we could have blocked it, we would have done it a long time ago." But we haven't been able to find enough of what the Underworld Demon can't dig through! ”

Diamond and Holy White Copper Juice is the strongest building material in the world, and its strength can make a four-star Golden Warrior stand still even if he bombards it with all his might.

But in the face of the excavation of the underground demons, it is not much better than a pile of rotten wood.

Kungo sighed, and secretly carved a mark somewhere on his body, and he felt a sense of disobedience just now. Now he does this kind of tidying, and every time he encounters a certain sense of disobedience, he will record it so that he can tidy it up later.

"Well, it seems like a stupid question. So has anyone tried to see what's inside the seal? Is there anything else in there besides the Underground? Kungo changed to a new question.

Isidor shook his head: "We're exhausted just by dealing with the Underworld, where is the strength to see what's inside the seal?" ”

"Ancestor Emperor Ming has seen it. He is the only fighting god recorded in history, he once went deep into the seal alone, and when he came back, he only said one sentence, 'There is the dark side of the world', and he never said anything about the seal again. ”

Agette explained.

Another sense of disobedience came to his heart, and Kungo added another stroke to the record.

The team quickly walked through the first two floors of the dungeon, and after passing by a team of six mercenaries, they came to the real third entrance.

"The entrance here can only be opened by the Royal Seal. Other times it's sealed! Isidor explained to Kungo as Agmet opened the door.

"Wait, I remember you said earlier that there are Night Oathers watching the seal, so they won't come out? Don't need supplies? Kungo asked curiously.

Isidore's face was a little difficult to look at: "When the gentleman sees them, he will naturally know!" ”

The other party didn't want to explain, and Kungo didn't force him to ask.

Soon, the gate was opened, and Agart had some of the Praetorian Guards to guard the entrance, and the remaining hundred of the most elite warriors followed them down to the third floor.

"There are five floors in the dungeon, but the fifth floor is larger than all the areas above combined!" When the team went down to the third floor, they didn't encounter the Underground Demon, so they quickly passed through, and when they entered the fourth floor, the atmosphere changed suddenly.

Originally, the dungeon had eighteen floors, each of which was a little smaller than the previous one, forming an inverted tower shape, but in the thousands of years of confrontation, the fifth layer and below have changed greatly due to the war and the corrosion of the underground demons.

Eventually, it was counted as a layer.

The fifth layer is the first layer, and it is all the layers that used to be.

"It looks like the seal may be broken at any time, and that nasty aura has reached the fourth layer!" Agat also put away the look that had always been improper.

Three four-star primary-rank Praetorian Guards were guarding Aget's side in a zigzag pattern. The rest of the three-star Praetorian Guards also worked in groups of three, walking around in a combat team to keep guard.

Only Kungo was carrying the horn gun with a big grin, and there was no tension at all from the others.

Of course, he was not careless, but his perception was far greater than that of everyone present, and he knew that although the atmosphere was bad, it was not dangerous.

"Oh? Someone's coming! Oh, or not people? Kungo's expression suddenly moved, and he looked at one place.

The Praetorian guards were immediately alarmed.

"It's the Night Oath!" Agart was relieved to see the sword in his hand turn ice blue.
