The door was smothered in dense layers of fungus, and the growth was still thickening. At this rate, the doorway itself would soon be buried.

Good thing he had arrived early and run into Zouken Matou along the way. Otherwise, finding the door would have been harder than climbing to heaven.

If he ended up trapped here and had to force his way out, he would probably feel guilty for the rest of his life.

He had found the entrance. Now he needed to open it. Forget a key—he couldn't even see a keyhole.

He would have to try something else. Fire was out; it would probably cause a massive explosion here. So what could he use?

Sajyou Manaka asked, "Do you know what fungi are?"

Yuan Shikai said, "No. I don't study them. How would I know?"

Sajyou Manaka said, "Explaining fungi to you in detail would be a waste of breath. I'll keep it simple."

"Fungi need to survive too. All they want is to reproduce, so we need to stop them from reproducing."

"Fungi can't withstand high temperatures. Try heat and see if it kills them. Antifungal drugs can also inhibit their growth."

"Phenol, formaldehyde, tincture of iodine, and mercuric chloride can all inhibit fungi too. Understand?"

...The silence was deafening.

"Or you could summon a Servant who can deal with fungi."

Yuan Shikai asked, "I can summon a Servant in this state?"

Sajyou Manaka said, "Why not? Right now, it's as though you're carrying the Root with you. Tsubaki still has one Command Spell, so she's still a Master."

"We're inside her sea of consciousness. You can perform the summoning on her behalf and call a Servant who can solve this."

Yuan Shikai said, "That works? Then what are we waiting for? Who should we summon?"
