After entering the fourth floor, Rein and his group found themselves in the middle of a ruined city. And they were also surrounded by several zombies and skeletons. There were broken buildings everywhere and the whole scene looked like as if it was taken straight from an apocalypse.
Interestingly enough, the power level of the undeads were vastly different from each other. Some of them were as weak as a civilian where on the other hand, there were extremely powerful ones too. It looked like suddenly a whole city had died and its inhabitants had turned into undeads.
As soon as they noticed the presence of living beings, immediately all of them swarmed toward them. Rein, Tasha and Stella immediately started to fight them.
The battle did not take much time and it was over very soon. Among the undeads who attacked, no one was too strong. So the conquerors were able to finish the battle quickly.
Stella took a look at the city and saw that there were a lot of undeads still left. The amount they just defeated was not even 10 percent of the total undead population. Tasha asked Rein if he wanted to sneak around the city or he wanted to defeat all the undeads first before searching the city.
Rein thought about it for some time and then decided to choose the second option. The detection ability of an undead was quite good when it came to detecting living beings.
So it would be very troublesome if those pesky undeads came to disturb them over and over again when they were searching the city. That was the reason why Rein decided to get rid of all the problems before starting the search.
So all three of them released their living aura more and more. They also spread their aura throughout the whole city in order to attract the undeads. This was a successful plan as the undeads soon started to move toward their location.
Rein, Stella and Tasha soon started the slaughter. Several magic spells and elements rampaged around everywhere. After about five hours of continuous fight, the city became silent once again.
The opponents of higher grades were also capable of doing the same.
The underground maze was very vast. Rein saw that the space of this place had been expanded by some sort of special dungeon logic. For that reason, three of them decided to split up.
They wanted to clear this space as fast as possible. That was the reason why they separated. Rein was still maintaining a connection with all of them with his network and he had already made sure that teleportation was allowed in this place.
So if they faced any danger that was capable of killing them, he would be able to teleport to their side immediately.
Just like that, the clearing of the fourth floor underground passage went very well and soon all three of them were done with clearing out all the opponents except for the boss. Yes, there was a boss here on this floor unlike the previous ones.
...
After entering the boss chamber, they saw a ghost king sitting on a chariot and he was surrounded by over a thousand soldiers. The minimum power level of the soldiers were at the yellow grade and there were 5 generals at the orange grade. And the ghost himself was at the red grade.
So far a single member of the conquerors were able to defeat all the opponents they had faced so far. But this one was different. Stella and Tasha would have less than 30 percent chance of winning in this situation. A slight mistake could even kill them immediately.
So Rein asked them to fight the soldiers and he himself tried to attract the attention of the ghost king and generals. This was going to be a tough battle even for him.
