The moment Leo arrived outside, he immediately went inside the one-story house near him. He didn't hesitate to throw the Captain's dead body on top of the pile of dead bodies inside the house.

After doing that, he made sure that no one was nearby before making his way out and return back to the location of the relocation area. Of course, before finally leaving, he first sent out an order to his Earth Elementals to go down the Storage room as he would be going 1 kilometer away hence they will automatically be unsummoned once that happened, which would definitely cause a lot of trouble to Ethan.

The moment he arrived, Leo immediately saw that at this moment the relocation area has been thoroughly improved.

The houses were now connected to one another with small wood mixed with vines, bridges interconnecting to each house. The roofs of the houses undergone an expansion in order to cover the small roads in between the houses, which they then turned into a kitchen to cook food to those civilians they have relocated. After all, because this relocation was rushed, the civilians weren't able to bring a lot of food, and most likely Ash had ordered a few of her men to bring or more appropriately to steal foods and cook them in order to satisfy their basic needs.

After a few minutes of walking, Leo finally saw Ash, still busy ordering everyone on what to do.

Quickly noticing Leo at her side, Ash turned around, "Leo? I thought you were busy in your operation related to the wall? Oh, it looks like you are indeed since this is the first time I'm seeing you wearing armor. So, what brings you here? Miss me? Hehehe..."

Leo just shook his head at Ash when she let out a cute giggle, "We indeed encountered a problem, but it's not really that much. The reason why I came here is only to inform you that I will be bringing everyone outside in here to help me. So, clear out some space for them to hide the moment they arrive here."

Hearing Leo's words, Ash was momentarily stunned before she shook her head half a second later and said, "I'm afraid that I can't do that. Right now, the houses nearby are full. In fact, Cassandra, Elizabeth, and Angel are now slowly expanding our perimeter so that more civilians could be relocated in this place. Therefore, what you are asking me would cause a lot of trouble."

"Oh..." Leo nodded his head in understanding. He then fell into deep thoughts to think of a new way. And after a few seconds, he finally thought of one, "Nevermind, then,"

After saying that, Leo then made his way back to the entrance of the sewer system. Without any hesitation, he jumped down and took out a torch to lighten up his surrounding before he quickly moved towards the exit.

10 minutes or so later, he finally arrived outside the south sewer. In front of him was the forest that Jeffrey and the others are currently hiding at right now.

Without wasting any time, he moved forward and started looking for them.

*Rustle!

Suddenly, a man's voice sounded behind Leo.

"Leo?"

Turning around, Leo immediately saw Jeffrey, and behind him was Matt and Venice.

"Great!" Leo can't help exclaiming in delight. "Immediately call everyone, I need everyone to help me with another operation inside."

Jeffrey nodded his head as he motioned for Matt and Venice to follow after Leo's order and gather everyone here. The moment they left, he then turned to look at Leo as he can't help himself from asking, "If you don't mind me asking, but what kind of operation would it be?"

"We will be infiltrating the top of the wall!" Leo said while pointing his finger at the wall behind them.

"That..." Jeffrey was immediately rendered speechless, out of shock by Leo's words. To be honest, he actually already knew how many soldiers were on top of the walls as they have spent their free time observing and counting them below through the help of a slave that was able to tame birds. The birds flew up and reported to them the numbers of soldiers on top of the wall which was an astonishing number of 2,500 soldiers. And according to Leo, they would be going in to infiltrate the wall which simply meant they would be fighting against 2,500 soldiers of the Silver royal family! Even if they have 1,000 men, with the Silver royal family's soldiers having the advantage, it would definitely be difficult for them to win, and this is just the mention of the top of the south wall. The moment they begin the attack, the rest of the Silver royal family's soldiers would definitely be alerted, meaning it would be 1,000 men versus 100,000 soldiers' fight.

"Isn't that a bit, unnecessary...?" Jeffrey can't help himself from expressing his opinion.

"Don't worry, we would only be infiltrating a small part of the wall, not the entire wall. So, this operation would only require us to slowly but surely replace the soldiers on top of a small part of the south wall until all of our men finally replaced them." Leo explained to assure Jeffrey that it wasn't really that dangerous.

"Oh..." Jeffrey could only nod his head after hearing Leo's words. He was actually still not able to understand what kind of operation it would be after hearing Leo's answer. But according to Leo, it wasn't that dangerous, so it should be something they can still handle.

10 minutes or so later, all 1,000 men were finally all gathered by Matt and Venice.

"I will go this time with 100 men first, while Jeffrey, Matt, and Venice, all three of you will wait here with the rest of the men until I return, do you understand?" Leo said.

"Okay!" Jeffrey, Matt, and Venice nodded in affirmation at the same time.

Leo nodded his head before going inside the sewer system first. The moment he got in, he immediately motioned his hand for Jeffrey, Matt, and Venice to send 100 men to follow him.

Jeffrey, Matt, and Venice nodded as they turned to look at the 1,000 men and said at the same time, "Group yourselves into 100, the group that finishes first will quickly follow after Leo!"

"Yes, sir!" All the soldiers nodded before quickly grouping into 100. And as soon as a group was able to finish gathering 100 men first, they immediately made their way to follow after Leo.

Seeing the incoming 100 men, Leo immediately began leading the way.

After 10 minutes or so, Leo along with the 100 men slowly made their way to the surface. Then, following after Leo's lead, they made their way towards the direction of the one-story house.

The moment they arrived, Leo turned to look at them and said, "Group yourselves into 20 men each."

All the 100 men nodded in affirmation as they quickly grouped themselves into 20 men each group.

The moment they finished, Leo nodded and said, "The first group, follow me to the roof, while the rest will observe closely on what I do below while hiding in the dark, understand?"

All the 100 men expressed their understanding.

Leo then chooses a random group to be the first group and leads them to the roof of the one-story house.

The rest also quickly choose an inconspicuous spot to hide and watch what Leo was going to do.

Moments later, a group of 20 soldiers was walking towards the door leading to the top of the wall, and without anyone of them expecting it, they were immediately attacked by Leo along with the first group.

After a few minutes, all the 20 soldiers died without Leo's group having any casualties.

"Take all the dead bodies inside the one-story house and then wear their armor." Leo ordered the first group before moving forward to clean the bloodstain on the ground by following what Ethan had done awhile ago. He created a circle of water, which was easy and doesn't require any sort of incantation, it was just like forming a Fireball spell, and then he threw it on the floor to quickly wash away the blood.

Meanwhile, the first group quickly began carrying the dead bodies inside the one-story house that they jumped down from. The moment they got in, though, they were momentarily surprised as they saw that there were actually already a lot of dead bodies piling together. They quickly shook their heads to put their surprise to the back of their heads before they continued walking in as they put the dead bodies they were carrying on the pile of dead bodies. Afterwards, they began taking off the armor of the dead bodies as they then began wearing it.

The moment Leo got in, he immediately nodded his head as everyone was already fully equipped with their armors.

"Quickly wear your helmets to cover your face thoroughly and go in through that door to reach the top of the south wall. You will meet a Captain there, which is Ethan, just send an okay signal with your hands to show him that I send you there." Leo quickly briefed the 20 men on what to do.

"Just a thumbs-up is okay?" One of the 20 men can't help asking.

"That is also okay." Leo nodded.

"Okay!" That man nodded before motioning for everyone to follow after him towards the door.

The moment they got inside, Leo then walked back to meet with the remaining 80 men as he asked, "Did you see what we just did there?"

All the 80 men nodded in confirmation.

"Just repeat the same step over and over again until no one in here remains. Just attack those walking towards the door, not those that came out. If you notice that they are Logistics personnel, specifically they are carrying some supplies, don't attack them. I won't explain why, just don't attack them. And last reminder, you will come in through that door with the same number as the soldiers that you have killed, you cannot go more than what you have killed, and when you arrived on top of the wall, you will meet a Captain which is actually Ethan, just send him an okay sign, a thumbs-up is fine as well, to signal him that I send you there, understand?"

All 80 soldiers nodded their heads in affirmation.

"I'll be going now to bring the others. So, all of you here should be careful and not mess up because the lives of the others on top of the wall depends on all of you present here. And please, don't forget to wash off the stain of blood once you are done killing the soldiers in the same way as I do." Leo reminded again before leaving to get another batch of 100 men.

To be honest, Leo was actually a bit worried that they will mess up, especially since there is no Leader figure in their group right now. But, if he keeps on guiding everyone step by step even though they've already seen an example of what to do, they would start to depend on everything on him. It might be fine doing it once, but to repeat it over and over again might just result in them not having the ability anymore to think on their own. He doesn't want his own army to be like that. What he wants is an army that can adapt to any given circumstances, especially in a situation where they lack a Leader figure to command and guide them on what to do, which means they need to learn how to depend on themselves, and the best way to teach them is through a life-threatening situation such as this. If they mess this up, then that means all of them present here would die.

And aside from that, he had also specifically mentioned that the lives of the others on top of the wall depends on all of them present here so that they would be extremely careful and would try their very best not to mess things up since it would not only cause them to die but the others as well. This will teach them to trust each other and give them a sense of camaraderie amongst one another as well.

Leo can't help smiling mischievously while thinking those thoughts in his mind, "Our situation right now is the perfect place to train really good soldiers, hehehe..."
