In order to find the potassium nitrate, they needed to create landmines. Two of them carefully looked for a cave and they were succeeded to do that.

In his mind, Potassium Nitrate mostly can be found inside the cave and rocks. Yes! They can find that material under the volcano as that place was surrounded by different kinds of rocks, but the main problem was the Notorious Centaur could locate them once again and that it will be bad for them.

He looked at her with his serious eyes, asking the woman beside her. "Emma, would you like to come with me inside this cave? I don't mind if you didn't want because I messed up the last time we went to the cave." He slowly walked towards the cave, waiting for the woman to respond.

Furthermore, Emma looked at him with persistent eyes, couldn't see that she was hesitating to answer his question. "Of course, Riku! Both of us go here which means we must come back to the Arzotoc village."

He just simply smiled in front of him, didn't let Emma see his expression. At the same time, aware this woman would never leave him. Why? It was her attitude and this was what Emma was so he couldn't do anything about that.

__

To begin with. In front of them was the entrance to the small cave. Based on its size and height, he could easily tell it was enough for one person to pass.

"I'm going first, Emma." He said in a deep tone, even though didn't see anything inside.

She raised her brows, knowing it would be dangerous for them to enter this cave without seeing anything. Or to be exact, they could not tell if there was a trap here or when the monster would attack them.

And all of a sudden, Emma tugged his clothes, trying to say something to him. Although she was well savvied that man was doing this for him, still, she can't take to gamble their life here since they were almost to finish their task here.

"I'm good, Riku. You must not think too much about me." She said politely, after that, positioned in front of him, saying that she would like to lead this expedition.

"What are you doing, Emma? You should stay at my back and regained some of the strength lost to you." He said in a high tone, protecting this woman at all cost.

"I already said it to you, Riku. I don't want to become a burden for you on this expedition. Aside from that, I'm the most capable person to do this job, and you are not aware of my capabilities." She responded, then gently tapped his shoulder, showing that he can't do anything to change her mind.

Well, she was quite right. Although Riku knew Emma for several weeks, still, he was clueless about this woman's capabilities. Yes! She was been with him fighting different types of monsters, given by her high physical strength and the speed that she had, yet, it was not enough to determine her true power.

"I'm not thinking that, Emma. All I want for now is you should stay in my behind so you can help me if there's a monster approach us." He explained to switch their position.

"Jeez, Riku, why are you so hard-headed? I have a skill that could help us lighten up the place. So if I lead this expedition we can lower the chance of getting attacked by the monsters." She also explained, at the same time, reasonable in the given circumstance.

At this point, he was speechless after seeing Emma's black knife releasing a green light that sufficient to see the object ahead of them. He admitted that he was impressed to see this gleaming skill, couldn't help himself to ask Emma how she was casting it.

"Wow... It's amazing, Emma. How you can supposedly do that?" He asked her along with astonishment in his eyes.

And all of a sudden, Emma had a smirk on her face while looking at him maliciously. It seemed before she says the reason behind this skill, she wanted to know more about him which really piqued her attention.

Because of the light, he was able to see her face and immediately felt something uncomfortable with this woman's expression. "Eh? Why are you looking me like that?"

First, he thought Emma remembered the kissed happened between them. So he really bothered, knowing he would start to be more uncomfortable staying with her.

"If you want to learn about my skill. First, you should tell me how did you put the black armor that your body had earlier." It appeared she didn't forget that skill as it was the first time she could see something new.

He sighed of relief after she didn't mention that embarrassing occurrence happened to them. But the followed-up problem transpired since he had no idea how he was going to explain it so he just simply responded like this.

"Oh, are you must talk about that skill? It's too complicated to explain that magic right now, so I think I will tell it once we came back to the Arzotoc village?" He responded nonchalantly as it was the best way he knew to stop this woman from asking her.

Yet, Emma had no reason to teach him if Riku didn't do the same thing. She smiled again and said. "Is that so? Then you will be able to know about that skill once we come back to the Arzotoc village."

He secretly gritted his teeth, but couldn't take to blame this woman since she already taught him how to use the [Mana sensing]. He shrugged his shoulders, then continued to follow her path in this unknown cave.

"Fine. Let's teach others once we safely get out of this forest."

A green light was the only one they could see inside, wet surface and the smell of earth. Yet, it was not enough to determine if there was no monster existed in this cave.

It happened for several minutes until the structure of the place suddenly changed. To describe it, two people could pass in this straight path at once, on top of that, it divided into three different directions as the place lightened up by Emma's magical light.

At this juncture, Emma was confused about which path they were needed to take. Nevertheless, Riku remained calm, knowing that they didn't have to get deeper cause once they saw the potassium nitrate their task here was all done.

"Riki, you decide? What do you think is the best path to take right now?" Emma asked him in a deep tone.

"Take whatever you want, Emma, it doesn't matter. Since we didn't have to go deeper, in the next turn I think we could find that material." He replied and followed Emma as she chooses the right path.

Everything was ordinary until Riku was dumbfounded for something along with a broad smile on his face. It must be, he already found out the exact location of the potassium nitrate?

Above them was the white color that was similar to snow. Its thickness and transparency were enough to determine to himself that was the right materials he was looking for. It was hung on the ceiling of this cave, even though it was the position, still, he was happy to see that as they could immediately leave the place after collecting the right amount they needed.

"Emma, you should stop now and I think will not take any longer here." He said confidently as he was certain with this element. Remember, he had a high IQ, at the same time, he studies to know more about the world he belonged.

She followed his order without making any hesitation. Then looked at the place where Riku's index finger was pointing. "Okay, Riku. You are quite confident so I could tell that you are certain about this."

"Of course, let's finish our job here."

As soon as they spotted the material, Riku and Emma took the potassium nitrate without making any second thought. It took almost thirty minutes until they collected two sacks of it.

For him, it was enough to create landmines. He jumped back to the surface, after that, he swiped the sweat that formed on his face. "Emma, we are done here. Come on we should leave this place before the monsters came after us."

...

By using his [Fly] skill, Emma and Riku left the Assima forest. On top of that, he was sure one day or two days weren't enough to create landmines.

While in the sky and the sunlight was mildly touching on their bodies. Out of the blue, Emma asked him which piqued his attention. "Riku, how much are you sure that making your invention could save the Arzotoc village from the big invasion that would happen sooner or later."

Riku chuckled at him and simply replied to her like this.. "My invention isn't created from the magic. So it means no one ever could detect this hahaha!"
