The wall vibrated violently, and the pit in the center of it sank even more severely, forming a hole. The cave eventually expanded and deformed to become a larger opening.

This time, the process of the wall changing out of the hole was even more intense than Erhes had seen before. What is the reason for this? Is it because of that? In order to make a hole in this kind of wall, there is a certain condition that needs to be met, and that condition is to smear the saliva of the Niwa lizard, or something of similar quality. And this time the change is so drastic, maybe it is the relationship between the cat Niwa who has smeared too much saliva.

Those walls are afraid of those things, and as soon as they come into contact with them, they will naturally avoid them, which should be similar to the characteristics of shy grass that atrophy when touched.

“…… Stupid cat lizard, your hole is too small, so I can't even get into it. If you can, it's at least half a double wider than it is now. ”

Instead of enlarging the hole as Erhes asked, Niva the cat thought of another way. Niva the cat suddenly turned her head and pounced on Erheth.

"Uh......h What are you going to do, go away...... Ah, huh, it's easy to raise, don't, don't tease me like this, woo, huh, ahhhhhhhh ”

Niva the cat pounced on Erhers, her tongue sticking out widely, and licked her body until her whole body was evenly covered with saliva from her mouth.

…… This guy is really, it's not stupid at all, is it? It's a way to get through that little hole more easily, but Erhers doesn't quite accept it.

The saliva of the cat Niwa has a lubricating effect, and in addition, the deformed wall in front of her is afraid of the saliva, which makes it easy for the cats Niwa and Erhes who are covered with those saliva to pass through the small holes in the wall that are concave and deformed.

Erherth followed Niva the cat and burrowed into the little hole. Erheth and Niva the cat crawl through a narrow tunnel. They rely on the resistance effect of those saliva, and it is not difficult to move forward in the narrow tunnel formed by the cave **. However, the tunnel they formed, after they passed, continued to stimulate the expansion of the tunnel wall without saliva, and after a few seconds, it quickly contracted and closed again, becoming a wall blocking the way.

The tunnel wasn't very long, and Erhes and Niva the cat crawled for only a few hours before they reached the end of the tunnel. At the end of the tunnel was a wide walkway that cut across the front.

This wide passage is a closed road, but Erhes has an impression of it. The walkway in front of Erhers was the one she had taken from her room full of vines and vines to her private space in Valis.

Erhes admired the cat Niva a little, as it moved in a narrow tunnel in the darkness and without direction, and arrived at the tunnel in an almost straight way. How, exactly, is this possible?

Erhers looked up at Niva the cat, and she saw that Niva was dilating her nostrils that grew above her flat mouth, inhaling vigorously, as if searching for the smell of the air.

…… Did Niva find the direction of the scent of the green lizard's companions, and then choose the nearest path to get there, all by smell?
