After killing the 5 Mages of the Black organization, there were only 6 remaining men alive inside this large cave. So, Leo quickly went to look for them to finally finish everything here.

After a few minutes of running, Leo finally spotted the remaining 6 Black organization soldiers. They were spread out all around the area, hiding and hoping at the same time, that the assassin wouldn't be able to find where they were hiding at.

Unfortunately, their wishes weren't granted. Leo was an assassin and was trained through a ruthless way by his Master to be able to fight in the dark. So, the Black organization soldiers hiding in the dark wouldn't work at all to him, especially since the remaining men alive were just ordinary Humans and not Mages who can cast Magic spells to conceal their own presence, which he could actually still find if he looks around carefully.

Leo was soon able to find them one by one. One hiding around the earth walls that the scarface Mage had casted before. Two on the very side of the cave. And the last remaining three had hidden by acting as one of the dead Black organization's men.

Well, the last 3 had taken Leo a lot more time to find compared to the others. If he hadn't known that there were actually still 3 more remaining men alive, then he definitely would have really missed them.

What could he expect from someone in the Black organization? If they can even do things that could endanger the entire Human race, then surely they can also do something really disgusting too, right? Such as hiding using the cover of Human intestines, broken arms, and etc...

They were really cruel, to be honest. They were already going to die anyway, so they should have just left their dead comrades to rest with an intact corpse instead of digging out their innards or cutting a part of a body to cover their own. Or instead of using their dead comrades, they should have just used the dead Magical Beast lying around the place, since there were hundreds of dead Magical Beast, so he would surely take a very very long time to find them, which eventually would make him give up in the end. Hence, they could have successfully hidden themselves.

Those 3 people really proved the saying, a wicked person is the one who is the most afraid of death. Even they wouldn't hesitate to use their companions' dead bodies in order to live.

Unfortunately, Leo wouldn't allow such beings to have an easy way out. Although he was the one who had killed those mutilated bodies, he still respected their corpses since he still left an intact corpse for them. And since those 3 men had done something really cruel, then in return, he also did the same thing to them. In their case, though, they were allowed to watch their innards being dug out and a part of their body being cut by the Earth Elemental before they finally took their last breath.

No matter who the enemy was, Leo was always taught by his master to respect them, alive or dead, especially in the case of those Black organization's men that he had first assassinated since they were fighting courageously against Magical Beast before being killed by him. Although they were wicked people, what they did was still something worthy of a little tiny bit of his respect.

Sadly, the ones who didn't respect their corpses were their own comrades themselves.

After finally killing everyone, Leo then walked straight towards where the cave of the 1 Star Magical Beast was. Beyond that cave was where the 12 pieces of large Mana stones were located. Although he knew that it was the goal of the Black organization, after being strengthened by the large Mana stones himself, it had also become his goal now.

Whatever was the actual goal of the Black organization, removing the 12 large Mana stones or using them for themselves. Since he doesn't know, then he might as well just use it to strengthen himself.

Blocking a water pathway doesn't literally mean that a person had really blocked it for the whole eternity. The water would still look for another pathway to cross towards what lies beyond the blocked path.

So, despite Leo stopping the Black organization from getting the 12 large Mana stones this time, that doesn't mean that he had also stopped all of the organization's future movements.

The Black organization might change their plan after this, or they might go to the South Sewer. Leo could only assume their next action. But the one thing he knows for sure was; whatever the Black organization planned to do, the best way to counter it was to become more powerful himself.

However, getting the 12 pieces of large Mana stones wasn't that easy. A 1 Star Magical Beast was expected to guard the inside of that cave. Leo doesn't know why was a 1 Star Magical Beast guarding the large Mana stones when they should be the first ones to use them. But, since they didn't, then he would gladly take it for himself, in order to prepare himself for whatever plan the Black organization had in mind for the future.

After a while of walking, Leo finally arrived at the entrance of the 1 Star Magical Beast cave. Powerful pressure made out of Pure Mana could be felt at the entrance of the cave just from standing outside. Obviously, that was what the 1 Star Magical Beast used in order to keep away the other Magical Beast from his turf.

"The fight had lasted for less or over 5 hours, but there was still no sign of any 1 Star Magical Beast appearing out of this cave..." Leo suddenly said out of curiosity.

In the West and East Sewer, Leo had seen for himself that there was a clear boundary between the territory of the 1 Star Magical Beast and the weaker Magical Beast. But, at this time, the weaker Magical Beast had long already crossed that so-called boundary. In fact, the weaker Magical Beast could already be found just right beside the entrance of 1 Star Magical Beast cave.

So, the 1 Star Magical Beast should have already shown its presence a long time ago to stop the intruders from going any further to its own territory.

"Surely, there is something wrong here!" Leo muttered to himself before carefully going inside the cave.

Just like what Leo had expected, there was no 1 Star Magical Beast in this cave. But there were signs of its presence in the cave, such as its pressure outside of the cave could still be felt. The only question though was how did it disappear?

However, that wasn't the important part here...

"Since no one is guarding, then don't mind me getting all the 12 pieces of large Mana stones!" Leo said full of excitement in his voice.

If a bank has no one around to guard the place, a thief could naturally get all the cash inside, and on top of that, as many as the thief wanted.

That was the same case for Leo at this moment. Since no one was around the cave to guard the 12 pieces of large Mana stones, then what was he going to wait for? Without wasting any more time, he decided to and get all the large Mana stones, and escape this place as soon and as fast as possible.

Leo quickly went to another cave inside the 1 Star Magical Beast cave. That was the place where he would expect to find the 12 pieces of large Mana stones, so he needs to go through that cave first.

Soon, Leo finally saw the 12 pieces of large Mana stones embedded in the top of the cave's ceiling. Quickly, he summoned an Earth Elemental as he then ordered it to take away all the large Mana stones.

Afterwards, Leo excitedly left the place along with his Earth Elemental carrying the 12 pieces of large Mana stones.

Arriving outside of the 1 Star Magical Beast cave, Leo quickly summoned 2 more Earth Elemental to cut the already dead Magical Beast bodies in the area into pieces before putting them inside the net bags he had bought.

Almost everyone from the Black organization was dead. So, Leo harvesting their own harvest wasn't a problem anymore, since no one would know anyway that it was actually the Black organization that killed all of these Magical Beast. Even the leader who had unfortunately escaped his grasp wouldn't necessarily be able to recognize that what he had taken out as his kill was actually theirs.

Anyway, the leader would be really foolish if he dares to argue with Leo that what he had claimed was actually their Black organization's kill, right? Doing that would be really stupid of him since it's the same as revealing to everyone his real identity.

After enough of the Magical Beast bodies got cut into pieces by the 3 Earth Elemental, Leo then carefully put the 12 pieces of large Mana stones inside the net bags, hiding them carefully and inconspicuously.

"It's time to leave this place!" Leo said before slowly walking towards the exit of this large cave.
