Since she became this body, Erhers believes that her sense of smell has become different from that of human beings, and she has become more sensitive, making it easier to smell the distant air and distinguish which species are composed of the scents it emits.

Unfortunately, no matter how much Erheat used her nose, she couldn't smell the scent of her trapped green lizard companion wafting through the air. Erhers even thinks that the smells, in this space of tunnels and walls, should have been blocked somewhere, and the smell should not be easily dispersed and smelled.

So, what is Niwa the cat looking for in the air? What special cues can she find in order to move forward as she pleases in this labyrinth-like environment without getting lost?

"What are you looking for? Smells? Did you find me by those scents? So, you're trying again, looking for your fellow green lizards that way?"

Niva the cat had her tongue on her lips and nodded to Erhers with a smile on her face. However, it immediately explained to Erheth what the smell it was looking for. The smell wasn't the smell of the Erhes or the green lizard itself, but the smell of itself.

And the medium used to cover those smells is to use the saliva secreted by the mouth of the cat Niwa. The saliva slain smeared the creatures, leaving a trail of smell along the way as they moved. Niwa the cat is looking for the path formed by the traces of those smells, and she has searched all the way to find the creatures that are covered with its scent. Erhes is one example.

However, this way of finding smells by saliva also has a disadvantage, that is, even if the smell is stained on various objects, these smells will not change depending on the object covered, and the smell emitted by those saliva will still be the same. Therefore, if the smell-staining objects are scattered and cannot be seen, it is impossible to tell what the smell-stained objects are actually the things.

Niva the cat admits that finding Eherth was pure luck. Niva the cat knew that this Erheth had saliva on her, but not only her, but also many creatures or artifacts that were stained with that saliva, and it was really just a matter of luck to find the same smell and smell of other things from these things that smelled the same and were scattered around.

This time, Niwa listened to Erhes's request to find the green lizard companion that was stained with the smell of her saliva, and she could only rely on the smell of the same smell from all over the place to find it one by one, and see if she was lucky, and if she was lucky, she could find those green lizard companions as quickly as possible. If you're not lucky, it's going to take a long time. Moreover, the longer it drags on, the more it is difficult to guarantee that the lives of those green lizard companions will not be threatened.

"Ah...... Cat Niwa came here, don't look for it yet. There is movement nearby...... Come here. ”

Erhes waved to Niva the cat, and the fellow ran towards Erhes like a loyal dog dragging his tongue to his mouth, with wet saliva. Erheth and Niva the cat stayed in the tunnel, and they randomly found a fork in the road and turned into it, facing a wall. Erhes asks Niva the cat to use saliva to stimulate the walls, using the wall's saliva-fearing properties to create a cave for them to hide into.
