After filling my stomach with eel, both of us, a human and a plant, entered the dungeon.

Being in a cave should make the area dark, but it was bright as if it was outside during the day. It was because there are some type of plan that emit light all around the cave. From wall, ceiling, and even the floor, there are several of these plants whose leaves emit light. Even after being stepped, the light won't dim.

"Sunny. Your friends?"

Sunny shook her flower head. Then she magically, made her flower head emit light like the plants around here.

"You can do that too? Doesn't it mean they are your friends or similar species? Both of you can emit light after all."

Sunny shook her flower head again. This time it shook faster than before.

"Sorry sorry. I know you are different. You emit light on your flower, while these plants emit light on their leaves. That mean you're different."

This time, the flower head nodded and dimmed its light. Even plants have feelings.

"Come on, we're moving."

As I told Sunny to go, Sunny wrapped her root around my waist and we're entering the dungeon.

After all the monsters we defeated, and that corpse Sunny used as fertilizer for her nutrient, Sunny has grown considerably… smaller?

"Sunny, did you get smaller?"

As I said that, Sunny suddenly change her size into bigger flower. Her sunflower flower head is now about the same size as my head from the size of my fist. Her root also become bigger and thicker as well. How can I know? It's because her roots already wrapped on my waist tightly.

"Too tight! Too tight!"

Seeing me suffering, Sunny loosened her wrap and let me catch a breath.

"Huff… I see that you can grow bigger and smaller. But please don't get bigger again when you're wrapping your roots or vines around me, okay?"

Sunny dropped her flower head dejectedly. Then raised it a bit. Is that how she apologize?

"Apologize accepted. Now let's see what kind of treasures inside this dungeon."

Somehow, my Divine Vision is affected by the mana inside this dungeon. I guess it's because the purity of mana here since no human other than me has ever entered here and affecting the mana. This is the first time my Divine Vision doesn't work well.

I can still see around me, see-through objects, and zoom to distant object, but the effectiveness is different than when I'm outside.

Well, the good thing is at least I know that my Divine Vision has a weakness. It doesn't work well in a place filled with mana of high purity. Now I just need to find something to get rid of this weakness. Maybe using a scope will help me see further. Even better if there's an enemy whose vision is unaffected by mana with high purity. Then I just killed it and gained its vision. I hope I can find one here.

So I made a new plan with Sunny. Instead of having Sunny helped me like before, I intend to defeat the monster here on my own without using magic or Sunny's help. At least one of them. If there are multiple enemies of the same type, I just need to defeat one of them without magic, then after defeating one, I can use magic and Sunny's help to defeat the rest.

When I told Sunny about this plan, she shook her flower head and rejected the idea. I guess she just want to be the one to do the last damage so she can grow. Buy finally after telling her that I will buy a high quality vase for her, she finally agree. Well, it was just for me to fight each type of monsters alone so she doesn't actually protest heavily.

Don't tell me that Sunny did it on purpose so she can get something from me? How smart! As long as it's something I can get, I'm fine with it though.

The first monsters we encounter inside the dungeon is goblins. Weak. Too weak. But the numbers of goblins is about fifty of them. Only ten of them in front of us, while the others are nearby but didn't notice us. They will come as soon as they hear fighting.

I can be sneaky and kill them one by one without alerting other goblins, but it will take a long time and annoying. So once I see them, I just pierce my spear on one of them.

The goblins now become alert of our presences. And since I have defeated one of them, Sunny decided to join.

Sunny left my body and walked on her roots. Then on her stalk, three vines appear and from it, the vines attacked the goblins. Sunny also shooting seeds from her flower head as well.

"What? Do you want to fight on your own?"

Sunny nodded as she heard me.

"Then I'll leave these group to you while I take care of the other groups."

Since I have killed one goblin from the first group, Sunny is now facing nine goblins. Well, as long as the goblins' attack can't reach Sunny's main body, she will win undoubtedly. Although it may take time since her attacks is still weak.

While waiting for Sunny to finish, I can just defeat the rest of the goblins. Let's see if I can defeat all of them unscathed while not using any magic. After defeating the first goblin, I didn't notice any change with my Divine Vision. Maybe it's because goblin doesn't have any vision ability. Or maybe it's because just defeating one of them isn't enough.

I can find the answer after I finished all these goblins.

I let Sunny take care of the first group, and while they are distracted by Sunny's vines, I passed them and get to the next group.

Just like before, this group also has ten goblins.

Since I don't want to use magic, I'll try defeating them all without getting myself out of breath. One goblin need to be killed in one shot. If possible, multiple goblins in one shot.

I threw my spear at the goblins standing in a row, and managed to impale two of them. Eight more to go.

Then I approached the goblins and punched their faces one by one. I also letting them get a few hits on my body. Thanks to this perverted training method, my defense has raised. So it's impossible for the weak goblins armed with clubs to hurt me.

After the last goblins of the group is killed after I broke its neck, I picked my spear and prepare to throw it to the next wave of goblins.

The next goblins come from a narrow tunnel so they are running here in a row. And this throw pierced four of them. Easy.

"Taste my punches! And maybe sometime my kicks! If you're not ugly, you would have a taste of my head-butt!"

They are ugly so I didn't use any head-butts. Why would I get my face so close to those things on purpose?

Soon, all forty goblins are defeated by me alone. And of course I'm out of breath. But since the battle is over, I can get some fresh air with magic instead of breathing in this place covered with goblins; corpse.

Now let's see how Sunny is doing.

She's doing extremely well. In fact she has already defeated 5 out of the nine goblins.

She wrapped her vines around the goblins and shoot one goblin with seeds. All four goblins are wrapped around her three vines with one vine wrapped two goblins.

Then Sunny shot one goblin while also tightening the wrap around the goblins' neck. The seeds are aimed at the goblin's eyeballs.

But the vine wrap is not enough to break their necks. That's why Sunny decided to shoot them one by one.

Just as I approached Sunny, she let go of the goblin that she shot. Now only three more to go with each vines wrapped one of them.

"Sunny, can't you just swing those goblins around with your vines? Just smash their heads to the wall or the floor."

Sunny stopped shooting the next goblin and looked at me for a while. Then he returned shooting again.

"What? You're still not strong enough to lift them up?"

Sunny nodded at my word.

Despite her quick growth during this training, she's still not strong enough to lift a goblin. Maybe after a few more battle, and few more nutritious corpses as her fertilizer, she will be strong enough to lift a monster.

"Do you want me to beat them to near death?"

Sunny nodded at my suggestion. Looks like even she's also bored of how repetitive her actions is.

I just stab my spear to their chest and let Sunny shoot the chest part of the goblins.

All the goblins here are defeated. It was an easy for both of us. But there's something I learned from Sunny's fight.

It's that Sunny's potential to get stronger is much better than any other type of monster. So why is her kind not popular as contracted monster? Maybe it's the fact that she started weak. No one would have thought that her kind are capable of growth. And even those who understand, they would have thought that raising her is a pain.

There's also one other thing I'm curious about.

"Sunny. Before you meet me, you are just a weak monster, right? Then why is Lina refused to kill you and contract another monster?"

Sunny just raised her leaves and tilted her flower head. Looks like she doesn't know the reason as well.

Oh well, I can just ask Lina later. For now, it's time to conquer this dungeon.
