The three of them sneakily walked in the aisle, there were many black-clothed and purple-clothed priests patrolling back and forth in the corridors, Xiao Yu and the others had to be careful to avoid it, and they didn't dare to move when they encountered the purple-clothed priests, for fear of causing too much noise and attracting the black-clothed priests on patrol, it would be troublesome.

After passing through the tunnels, the three of them reached the end of the fifth floor, where a heavy metal gate was tightly closed, cutting off the way for Xiao Yu and the others.

"It's over, the door here is closed." Hal said with a frown.

"When will it open?" Xiao Yu looked at this metal gate, this metal gate was extremely thick, and it was impossible to force it open.

"I don't know, it's six days, a few hours." Hal said.

"Closed for six days?" Xiao Yu asked, "Is there any other way up?" ”

"Nope." Hal shook his head.

Xiao Yu's expression became solemn, did he just wait here? If you really wait a day or two, will the task still be done?

The voice of the "Didi" mechanical puppet attracted the attention of the three people, the mechanical puppet was fiddling with something next to the door, opening a piece of metal on a wall, revealing various fine equipment, and a long mechanical tentacle grew on the body of the mechanical puppet, inserting these fine equipment, "Found the door locking program, the program is being interpreted"

As the minutes ticked by, Xiao Yu understood that the mechanical puppet was trying to open the metal door, and it would take time to open the door.

In the distance, a purple-clad priest walked towards him.

Xiao Yu gave Hal a look: "Don't make too much noise." ”

"Yes." Hal's body gradually vanishes and enters a stealth state.

The purple-clothed priest was about ten yards away from here, and found Xiao Yu and the mechanical puppet, the purple-clothed priest opened his mouth and just wanted to scream, calling his companion over, a cold light flashed behind him, and a dagger pierced the back of his head, knocking him unconscious.

The dagger in Howl's hand slammed heavily on the purple priest's throat, and the purple priest's eyes gradually drifted and he fell to the ground.

After Hal killed the purple-clad priest, he dragged the body over and hid it in a hidden place.

"After reading, the door is open, five seconds, four seconds, three seconds"

"Didi, the door opens"

The metal door slowly opened, and the robot figure retracted the mechanical tentacles.

"Thankfully, the mechanical puppet hasn't run out of energy." Xiao Yu thought to himself, if there were no mechanical puppets, they would not have been able to pass through this gate at all, maybe they would have to wait outside this gate for a long time, and it would be difficult to predict what would happen in the middle.

Xiao Yu and the three entered the gate, and under the guidance of Hal, Xiao Yu and the three walked down the rotating stairs for three floors.

"There are a large number of mechanical giants in these two levels, if you enter these two levels from other places, you will be besieged by mechanical giants, only this is safe." Hal said that Hal had an obvious meaning, and that if Hal hadn't led the way, both he and Faith would have died miserably.

Hearing Hal's words, Xiao Yu smiled faintly.

Walking to the eighth floor, Hal took Faith and Xiao Yu into the elevator again, and the elevator accelerated and ran upward.

"It's almost there, we'll go straight to the top of the dungeon." Hal looked a little excited, his eyes shining with a strange light.

Xiao Yu couldn't help but glance at Hal more, and the frenzy and strange look in Howl's eyes made Xiao Yu a little vigilant.

The height of the elevator is climbing rapidly, and the numbers on the elevator are constantly jumping, 100 floors, 101 floors

The elevator stopped on the 108th floor.

"Be careful, the door is open." Hal reminded, clenching the dagger in his right hand.

Faith is also ready and ready to go.

After about two minutes, the speed of the elevator finally slowed down, and with a ding dong, the door of the elevator opened, and two guards stood next to the door of the elevator.

Two figures shot out and rushed towards the two guards respectively, and in a flash, they had reached the side of the two guards.

Sneak attack!

Hal stepped up behind one of the guards, stunned them with a sneak attack, and then stabbed them with a throat slash.

On the other side, the knight's spear in Feith's hand struck the guard's head with a concussion, knocking the guard unconscious, and a dragon flame slashed the guard.

The two men moved neatly and without any delay, and after killing the guard, they threw the guard's body into the elevator.

"Ding-dong." The elevator doors are closed and run downwards.

Xiao Yu looked at it casually, this was an incomparably open space, and he couldn't see the top when he looked up, if he hadn't known in advance that the city was underground, he would have thought it was in some strange space.

"This is already the top floor of the underground city, but we still need two hours to reach the central palace, and besides, this is the most heavily guarded place, we must be extremely careful not to slip through the cracks." Hal said.

"Two hours?" Xiao Yu glanced at the mechanical puppet beside him, this time and the duration of the mechanical puppet's energy coincided, and it seemed that it was still in time.

"Didi, the black-clothed priest was found ahead, the number is 50, and the distance is 100 yards." The stiff voice of the mechanical puppet reached Xiao Yu's ears.

Xiao Yu's color changed slightly, and he said, "Hurry up and hide." ”

The three of them found a corner to hide, and after a while, a large group of black-clothed priests walked past Xiao Yu and the three of them.

Seeing the black-clothed priest gradually walking away, Xiao Yu and the others dared to come out and continue to walk forward, relying on the detection effect of the mechanical puppet, they dodged the oncoming black-clothed priest in time, and the three of them were not discovered by the patrolling black-clothed priest, and there was no danger along the way.

After walking for about two hours, I finally saw the royal palace in front of me, which was very magnificent, with red walls and green tiles, and a large number of precious stones on the outer walls, shining and dazzling under the illumination of magic lamps.

"Follow me." Hal glanced at the large number of guards outside the palace and said.

Bypassing the courtyard wall of the palace and arriving at a side gate, Hal's figure flashed and entered the side gate, and after a while, Hal had some blood stains on his dagger, and walked out, saying, "Let's go in." ”

Xiao Yu and Feith followed Hal into the palace.

The trio weaves their way through the circuitous corridors of the palace, occasionally encountering one or two female half-undead, which Hal and Faith quickly kill and destroy the corpses.

"There are still ten minutes to enter the place where the Empress of the Palace is bedding." Howl's eyes gleamed with an evil light.

"Wait, we can't go in yet." Xiao Yu suddenly remembered something and said.

"Why?" Hal asked, confused.

"Let's clean up the half-undead outside before they come to the Empress's aid." Xiao Yu said.

Hal glanced at Xiao Yu suspiciously, Xiao Yu said that he would enter, and he couldn't force it, he suspected that Xiao Yu had other purposes.

Xiao Yu does have other purposes, Hal and Fei Si are of equal strength, and the two of them may not be able to beat the empress together, Hal is better to say, he is a thief, he can run away if he can't beat it, if he loses, Fei Si will have to take it there.

It's all here, Xiao Yu can't fail!

If you raise Feith's strength to a high level before entering, you can be a little more sure!

Therefore, before Fei Si entered the high rank, Xiao Yu would not go in to deal with the empress.

"Faith, kill those two guards."

"Yes, messenger." Faith replied, brandishing his knight's spear and rushing forward.

"Shall I help?" Hal looked at Xiao Yu and asked.

"No, you don't." Xiao Yu shook his head and said.

The suspicion in Hal eyes was even stronger, if he just wanted to clean up the guards around him, why didn't Xiao Yu let him assist Feith?

Those two guards were two ordinary elites of level twenty, and Fei Si was more than enough to deal with these two ordinary elites.

"Come out of a level 20 strengthening elite, the chief of the guard, Hal, go up to assist Feith, you can only use the stun skill, not the attack skill." Xiao Yu said that in this case, most of the experience points would be gained by Feith.

"Yes." Hal responded, his body slowly disappeared, a trace of coldness flashed in his eyes, although he was very puzzled by Xiao Yu's behavior, he couldn't disobey Xiao Yu's order, after all, he still had to ask Xiao Yu, and he had to rely on Xiao Yu to defeat the empress.

Bang, a level 20 enhancement elite fell to the ground, and taking out this head of the guard, Feith, gained most of the experience.

"Didi, run out of energy," the mechanical puppet said mechanically, the red glow emitted from his eyes gradually dimmed, and his body continued to change and contract, turning back into a round metal ball, which was quietly placed on the ground.

"Three hours have passed." Xiao Yu bent down and picked up the metal ball, and the mechanical puppet had completed its mission, and since it had reached the ground, the mechanical puppet seemed irrelevant. Xiao Yu puts the mechanical puppet in his backpack, and maybe one day he will be able to find a new C-type energy core, so that the mechanical puppet can be used again. I have to say, this mechanical puppet is really very useful.

With Howl's assistance, Faith took out hundreds of elites in a row, more than twenty of which were strengthened elites.

"Ding-dong." A white light fell on Faith's body.

"Advanced?" Hal was slightly shocked, he understood why Xiao Yu stopped to clean up these guards, he didn't expect that Feisi, a low-level geist, would actually advance. Hal then regained his composure, not knowing what he was thinking.

Faith was excited, brandishing the knight's spear in his hand and slashing another enhanced elite under him.

Xiao Yu glanced at Fei Si's blood volume, Fei Si's blood volume rose to more than sixty thousand, Xiao Yu glanced at Hal who was bowing his head and contemplating next to him, showed a faint smile, and said to Fei Si: "Okay, let's go in." ”

Xiao Yu walked towards the inside of the palace.

"Yes, messenger." Faith said, picking up the knight's spear and heading inside.

Hal glanced thoughtfully at Xiao Yu's back and hurriedly followed.

Xiao Yu was sure in his heart that Hal must have different intentions, even if he would not help the empress deal with him and Feith, it was very likely that he would escape at a critical moment, Feith's strength improved, and the certainty of winning was greater, and if Hal suppressed the empress, the possibility of Hal escaping would be greatly reduced, and Hal could also contain Howl.

The three of them walked towards the interior of the palace, this will be the last battle of Xiao Yu's quest, and it will also be the most dangerous battle.
