After resting for several minutes, I got up to where I found the rocky willow as it would be my next target. While walking, I try to figure out the best way to kill those trees, but I can't think of anything because the rocky willow is of the Plant/Earth element, and none of my transformations has abilities against that kind of monster.

While possession with the "scale" sword worked against the crab monkey despite being at an elemental disadvantage, I could kill it because its defences were not very strong in the neck area. Still, the rocky willows are different since they have a great defence, and their weak point, the core, is inside, so possession with "butcher" and "illusion" is out of the question.

Seeing all that, I only have one option: to use focused slash at maximum power and hope it can destroy its exterior.

So, with no other option, I will have to try it. To hunt the rocky willow, I will use "illusion" not only because of its increased agility stats but also because its ice element could help me when I fight.

...

Ten minutes passed, and I still didn't see any trace of the rocky trees. Maybe they are in a different area, or something happened that forced them to leave here?

When that thought goes through my mind, I see how a rocky willow begins to approach in my direction while waving its branches from one side to another. At that, its roots begin to spread and try to pierce my flesh, so I observe the trajectory of their attacks and begin to dodge them while I slowly approach.

This rocky willow is very different from the one I saw before. I am not referring to its shape, size or colour but to its behaviour because even though I was only 2 meters away from it, the rocky willow did not try to use its branches to hit me. Still, it kept using its roots to attack me, so I was not afraid to get closer, but I was prepared to move away because I did not want the thorns on its branches to hurt Kawaii.

When I was a meter away from him, he finally changed his attack pattern and wanted to use his branches to defend himself and hit me, but it was too late because my sword was ready to cut him.

Focused Slash!

A focused slash charged to maximum impact on the trunk of the rocky willow and cut it as finally as an axe chopping wood. The tree stopped moving and then fell to the ground, causing a loud noise that could attract another rocky willow. Still, because it took 10 minutes to find only one, it can be said that this is a blessing in disguise in danger.

[You have hunted rocky willow x 1]

The notification confirms its death, so I inspect it to find out why it behaves that way before picking it up.

But barely 10 seconds after its death, I hear the sound of the branches shaking in the wind, so I pick up the monster's body and check around me, only to see how another rocky willow comes in my direction with the same behaviour as the previous one.

...For some reason, I feel this will repeat itself for a long time. Kiii... (◔_◔)

...

After 10 minutes, finally, these rocky willows stopped appearing. They came every 10 seconds, so I had to manage to kill them and not run out of mana. I tried to lower the power of the focused slash, but it didn't work at all, so I had no choice but to use it at full power; combined with my few MP potions, I was in a somewhat precarious situation, so I had to retreat to prevent the noise from attracting more of these trees.

I have killed 40 rocky willows for now, so it's time to rest a bit and buy MP potions.

"SYSTEM αβΩ" searches for basic MP potion LV 3.

"SYSTEM αβΩ" starts the search and gives me the desired result.

[Basic MP potion LV 3]

[Description: A potion that helps to recover 100 MP per second for 5 seconds, and its effects do not increase if you drink the same potion again, Does it taste like blueberry or grape? Nobody knows]

[Price: 1 gold coin]

Seeing that my MP only reaches 500 and my purse is full, I buy 50 of these potions. I also bought potions of basic HP LV 3 because I only had 1 left of LV 2. In total, I spent 100 gold, but it's worth it.

Once I was 100% recovered, I went back to look for the rocky willows. I returned by the same path by which I went back. The curious thing about all this is that both the ground and the trees by which the rocky willows crawled while chasing me were beginning to recover at a slow speed, but that could be noticed, which shows the incredible vitality of the earth and also why the planet Unity has not been destroyed so far.

Let's consider the power of environmental destruction of a C-rank monster like the rocky willow that destroyed many trees around it while chasing me. You can get an idea of the destruction that could cause a B-rank or, even worse, S-rank, and I don't want to imagine the SSS-rank ones... better not think about that. I still have a long way to go to face monsters of those levels.

I put those thoughts aside and returned to concentrating on the surroundings, looking for the rocky willows.

After 6 minutes of searching, one appeared, only this one behaved differently. As soon as we made eye contact, the rocky willow began to shake its branches as if trying to threaten me. This behaviour reminded me of the rocky willow vs crab monkey confrontation.

Seeing that behaviour and remembering the previous experience, I decided to move away from that rocky willow, not as if I couldn't face it but seeing that its behaviour was different and for fear of Kawaii being hurt, I didn't do it.

As I walked away, the rocky willow continued to wave its branches, but I paid no attention to it and kept walking away.

When I was 10 meters away, I turned around and took out my binoculars to see what it was doing. I saw that the rocky willow began to creep in another direction, giving the impression that it was patrolling the area. It seems that these rocky willows are smarter than the previous ones. I think that if the tree had attacked it, it would not hesitate to retaliate. It would be best to stay away from those who behave like this.

As I see one approaching me, I continue searching for other rocky willows, which does not take long.

The rocky willow crawls and starts attacking me with its roots, so I quickly dodge it and run towards it, repeating the same scene I went through in my first fight against them.

Focused slash!

The rocky willow is cut in half and falls to the ground. Now it only remains that the other rocky willows come, and indeed it happens, but this time something different happens, and that is that two rocky willows arrive, but one of them stays in the distance waving its branches, which suggests that it wants to keep me at bay.

Well, he and I don't want to confront each other, and as long as he doesn't attack me, I won't do it.

While thinking about that, a rocky willow tree approaches me to confront me, so the fight begins again.

...

After 20 long minutes, they finally stopped coming. I completed the 150 monsters a while ago. Still, because these rocky willows kept coming, I got carried away by the heat of the moment and ended up hunting 120 of them. Adding the 40 rocky willows, I hunted before plus the 50 crab monkeys gives me a total of 210 C rank monsters.

These trees arrived every 10 seconds, so every time I killed one another appeared and as focused, slash had a cooldown of 10 seconds. I was like this all the time; fortunately, I bought the basic MP potions LV 3 that helped me recover my mana. In the end, I spent 24 of those potions.

As for the rocky willow at the beginning, it is still in the distance. It didn't attack me all this time, but it didn't let other rocky willows stop peeling either. It stayed in a neutral position.

I picked up the body of the last rocky willow and retreated into the distance while the rocky willow continued in its position and then left when it could no longer see me in its line of sight.

These rocky willows may be protecting something there. What? I have no idea, but it must be very important to them. Should I try to sneak into that area to find out what it is? ... no ... It is dangerous to go to an unknown place without knowing anything, even more so when the site is full of C-rank monsters.

I may go in the future, but for now, let's focus on getting better; this time, I got a +20 HP and +10 MP upgrade, which isn't bad. Now that I have nothing to do, it's time to head back. Too bad there isn't a mountain to fly to the city. If so, it wouldn't take long.

With that said, I start walking back to Fanfer city, avoiding contact with any monsters nearby. It's not that I can't just kill them. It's just that I'm tired of fighting so much, and I want to get to the adventurer's guild quickly so they can't take the mission to clean the tox dungeon.

...

After walking for how long, I finally arrived at the adventurer's guild, so I got in the third row to wait my turn.

I'm back. Huh? I'm back?! That's right. I'm sorry I'm a little late. Some unforeseen circumstances came up. No! That's okay! So... Did you hunt the 150 C-ranked monsters already? That's right, but they are a bit big, where can I put them? Come this way!

At that, the receptionist leaves her post to guide Marco to a workshop where she specializes in treating monster corpses. While Marco was happy to be able to complete this tedious mission to increase his adventurer rank, something else was going on in the receptionist's mind.

If one were to observe her, one would think she was calm, but in reality, in her mind, her brain was in total chaos. She was trying to control her huge accumulation of emotions, of which her disbelief, amazement and curiosity stood out, she knew that this mission was complicated, but if one was strong and made an effort, he could hunt 50-60 monsters a day, people who could complete this mission or 2 days or less could be counted as about 100, but to be completed in 1 was almost impossible, much less in 4 hours, he also knew that some adventurers cheated in this mission and hired other adventurers to help them hunt.

But they were never so brazen to finish it in a day, as they knew that despite the cheating, they had to make it look like they put in a lot of effort. Thinking about that, the receptionist discreetly watched the adventurer behind her and saw how he was showing a silly smile as if he couldn't wait for all this to be over. Seeing this, she didn't know how to react, as she didn't know if he was faking it or didn't care much.

He barely thought about it when they had already arrived at the monster treatment workshop. In it were all kinds of tools, devices and containers of all possible sizes to dismantle the monsters.

Wait here. I'll go get the crystal ball to confirm the veracity of his words. No problem, can I take the monsters out now? Sure.

At that, I start to take out the crab monkeys I have in the inventory because they are the only monsters that could fit in this room. While I'm taking out the bodies of the crab monkeys, the surrounding people begin to watch this with an astonished faces.

Seeing this, I remembered when I delivered a large number of bunnies in Torata, so I quickly composed myself and kept piling up the corpses of the monkeys as if I was playing Tetris.

Once I finished removing them, I wanted to get the bodies out of the rocky willows, but the space was too small, so I approached one of the employees who were working.

Excuse me, is there a more spacious place to put some monsters?

The employee Marco spoke to was astonished at the incredible number of crab monkeys he had brought in, so it took him a while to respond.

Oh? No... I mean, yes... I mean... what kind of monster is it? Rocky willows. Rocky... willow... how many of those do you have? 121, where can I put them? 121...

Hearing this number, the employee's brain stopped working. If seeing those crab monkeys was already terrifying, hearing that this adventurer brought the bodies of the rocky willows made his little bit of his brain short circuit. Everyone knows that crab monkeys are agile, battle-hungry and sadistic monsters, making killing them very complicated. At the same time, the rocky willow is a monster that attacks from a distance and has a powerful defence. Although fire can destroy its leaves, the trunk, which is its heart is immune to it, so it requires great strength and toughness like that of the crab monkey's claws to kill them.

Now, this guy who came from who knows where says he hunts 121 of them. Is this a joke or what?

Noticing that this guy stopped responding, Marco figured that this guy was trying to remember a place where he could put these monsters, so he waited a bit.

At that, the receptionist returned with the crystal ball, only to watch in horror at the crab monkeys in piles on some sort of building block, while the guy who had followed her waited for the shop employee to come to answer her question.

This... sir... Hello miss, wait a moment please, this friend is thinking of a place to put the rocky willows.

The receptionist looks at the employee and notices by his expression that this guy is in shock and can't react, but before she says anything, she remembers what she just heard from this adventurer and turns her head to confirm it.

Excuse me... you just said... rocky willow. Yes, I have about 121 of them, but their size is a problem, so I asked for a bigger place.

Hearing this, the receptionist falls into the same state as the shop employee, and the scene repeats itself again. Seeing this, Marco finally realizes the problem, as this also happened in Torata.

Ah shit, here we go again.
