We carefully bypassed the woods to the north, to the point where we could see behind the fort. The watch seemed to be taking turns looking around from the one built on each side, but as long as Leslie's magic persisted, there was no sign of noticing this one.

The Zirconia stronghold we discovered is believed to date with the construction of barracks that initially provide shipyards and perimeter security, and the construction of fences and fences surrounding the perimeter to prevent intruders.

On the north side there are traces of trees being felled - about two years ago they were cut to build this fortress. Since that time, plans to build military vessels to cross the border are believed to have been in motion.

"Glass, if the wood we've cut from here is used to build the fort, can we get any information?"

Trees are called stumps, even if they are cut and processed. His Royal Highness was right, when I touched the stump, I could feel what area of the fort it was used for.

(Oh my God... the Divine Tree still unites all the plants. Even the Zirconia plants are helping us, the covenant with the Divine Tree......!

I will sort out and reconstitute in my head the memories provided by the felled tree stumps. And I started drawing forts on the parchment I brought, using one of the stumps as a platform.

"Dr. Glass, is that... a map of this fort?

"Yes, as His Highness said, I was able to trace the memory of the tree cut here"

Relying on the moonlight to plug into the woods, I finished a simplified diagram and had Presha take a peek at it first.

"What... ho, really? Do you even know what a commander's bedroom is?

"The tree is alive even if it's cut. I had a conversation with these stumps and they told me about the fortification."

"Can we even do that...... Doesn't the glass mean we can bare the structure round if wood is used, no matter how robust the fortress"

"If it's about two years since it was built, it's fine. I think it will be difficult to get the call answered because the precision of the wood also diminishes over the years"

Mr. Presha and Mr. Raquel are looking at the drawings and thinking about a way in. The fence on the north side of the fort is provided with small doors for soldiers to enter and exit. At first glance, it wouldn't open from the outside, but there was a trick to open it from the outside, and even that seemed easy to open if I knew it.

The fact that only the Commander's quarters are divided will also greatly contribute to our operation.

And one more thing - probably used by many of the soldiers in this fort, a large one-story barracks. With magic, you can disable enemy soldiers here in several ways.

"Leslie, manipulating the flow of air is the domain of the Spirit of the Wind."

"... I can work on the ambient air and have it move. Not as fast as the Spirit of the Wind, nor can it be used for a wide range"

"Well... that's the kind of restriction you have"

Perhaps it would be better to work with the Spirit of the Wind on what I'm about to do now.

With Arlaune pollen, place the entire fortress under the rule of demonic flowers. All you have to do is flush pollen from the wind, but you can't let pollen enter the building for sure, and even if only some enemies have been hypnotized, it makes no sense if other soldiers alert you.

"... Brother Glass, I've come up with one thing"

"Hmm...?

"I can't change the direction of the wind, but I can make 'balls of air'. Besides, if we trap Arlaune pollen..."

"Oh, can you do that?

To the astonished Mr. Presha, Leslie makes him snort.

Working with Leslie makes Arlaune's pollen-targeted opponent a sleeping flying tool - the 'Hypnotic Air Ball', the power of which was to be tested for use by soldiers on the northern side of the fortress.

Summon Arlaune from the bulb roots and enclose the pollen in balls of air by Leslie. She said, 'I can get you to move,' but a small ball of air seems to be able to maneuver freely, flying straight towards the soldier on top of it - and.

"... Summoner, it worked, so my pollen reached the enemy."

While keeping his voice down, Roune complains with excitement. The soldier who was on top of him stopped moving to fall asleep, even though he would not be able to serve as a watchman for doing so.

It turns out that hypnotic pollen works without orders if you just let it sleep. Depending on how you use it, you will also be able to control enemy soldiers' movements and eliminate obstacles until they break into their destination.

"Magic is a great power depending on your ingenuity..."

"Lune, with the help of your pollen, you're going to miss the mischievous biocide."

"Phew... hey, summoner, the princess praised me, I'm glad..."

"Good for you, Lune. Doesn't sound too loud from here, it's bad when you're noticed."

Roune holds her mouth shut and with both hands. A little nervous about undercover assignments with kids, but now that Leslie and Arlaune found the combination to be effective, I didn't always blame Mr. Raquel either.

"Now we will go for the Commander's Office. Let's carry things carefully."

Strengthens the magical effect of Leslie erasing signs. Apart from ourselves, we finally entered from the back of the fort into the interior, having become 'an unrecognizable being even when we were there'.
