"Boom, boom, boom!"

The palace trembled, but saw the bookshelf in the corner slowly moving to the side.

Behind the bookshelf, you can see a door made of gold, with many ornate reliefs.

"There really is a mechanism ......," I couldn't help but be stunned.

"It seems that this palace is far from being as simple as we imagined......" Bai Maan also muttered.

When we got to the door, we found that there was a large gold lock hanging from it.

"Do you still want to find the key? That's too much trouble......"

I felt a lot of headaches.

The frustration of having a treasure chest close at hand but not being able to open it is very torturous.

"Don't do that, leave it to me."

Ios shook his head and stepped forward to gently place his slender fingers on the surface of the lock.

As the words came out of his mouth, a lilac glow also spread on it.

Click-

A few seconds later, the lock miraculously popped open on its own.

"Let's go, hurry up."

Ignoring our astonished gaze, Ios ripped the lock off, pushed open the door and walked in first.

Bai Maung and I hurriedly followed.

Behind the door is a long staircase, and the walls on either side are illuminated by a faint glow of precious stones.

After about ten minutes of walking, my eyes began to open up.

At the bottom is a small room with a very simple arrangement, except for a heavy-looking table in the center, covered with a red tablecloth.

And on top of that, a golden cup attracts the attention of all of us.

The room seemed to have not been touched in a long time, and everything from the table to the floor of the room was covered in dust. But the cup was shiny as new, spotless, and holy.

"That's it...... Grail? ”

Ios stared at the cup on the table and swallowed two mouthfuls of saliva.

Yes, something so holy could not be anything other than the legendary Holy Grail.

The three of us were momentarily fascinated by the beauty of the Holy Grail, and all of us froze in place, not having the courage to step forward.

After a few moments, seeing that none of us were moving, Ios gritted his teeth.

"Even if it is an artifact that has contained the blood of the Holy Son, it is now just an artifact without an owner. As long as you hold it in your hand, it's no different from anything else! ”

As he spoke, he slowly stepped forward.

"The hosts! It's too dangerous, or I'll take the Holy Grail for you! ”

Baiyun opened his mouth, trying to stop Ios.

"No, this is my territory, right, then the Holy Grail must have something to do with me." Ios shook his head and said, "If it does work miracles, then I will definitely share this miracle with you." ”

"Well, go Ios, I'm sure you'll be able to do it."

I gave Ios an encouraging look.

Walking all the way to the Holy Grail, Ios took a deep breath.

Then, slowly, he raised his hands and touched the two walls of the chalice.

"Wow!"

In silence, Ios' eyes suddenly widened, and then he let out a scream.

"What's the matter, Ios (master)?!"

Bai Maung and I hurriedly rushed forward to confirm what had happened to him.

"Hehe, it's nothing, it's just that this cup is too cold, which makes me a little irritated for a while."

Ios smiled a little embarrassedly.

"You guy, can you be serious? Almost scared the hell out of me! ”

Baixiang stroked his chest, very dissatisfied.

"I'm sorry, I didn't think the atmosphere was too tense, so I wanted to tell a joke......" Ios smiled a little awkwardly, "Anyway, I got the cup, but it seems to be a pretty decoration, and I didn't notice any magical power." ”

"Are you sure? If it was just a flashy decoration, why did the previous Saxon king build such a hidden secret passage to store it? I asked, a little curiously.

"Who knows, maybe he just likes to collect." Ios shrugged his shoulders and said nonchalantly, "This thing is very beautiful, and it would be nice to take it out and put it on display." ”

“……”

I couldn't say it, but I always felt that something strange about Ios.

I hope it's just a little bit of heart, right......

"Okay, okay, anyway, we've seen the secret passage, so let's just go up."

Ios didn't give me a chance to confirm again, and with a wave of his arm, he walked up on his own.

——

After all the tossing and turning, night has already fallen.

"Yawn—"

Baixiang covered his mouth lightly and kept yawning.

"It's strange that I, as a Heroic Spirit, feel sleepy." Baixiang said confusedly.

"Didn't we make a soul contract between us, I want you to sleep at night, so you have to be obedient." Ios laughed.

"This ...... How can you want to watch someone else sleep...... It's just too much! Bai Xiang's face turned red, but then quickly retracted, "What if...... I mean, if I can't stay awake when the night strikes again, who will protect the master......"

"Don't worry, I'll take turns keeping vigil with Shirou." Ios shrugged his shoulders, "No matter what you say, you can't be protected by two of us men, right?" It's going to make people laugh to death if you say it. ”

"What a troublesome host...... I like to mess around with things, and I just have a set of truths......" Bai Xiang sighed, "Okay, then I'll obey you for the time being tonight, and it will depend on whether you can give the right instructions in the future." ”

"Mmmm, next door is the bedroom for sleeping, my brother can't do anything else, and he enjoys things that no one can do." Ios laughed, "You can sleep first, I wish you a good night's sleep." ”

"Good dreams."

The corners of Baixiang's mouth twitched, but he nodded obediently and walked into the resting bedroom.

After Bai Xiang entered, Ios leaned against the window, bored admiring the starry sky and moonlight.

"Ios, you ......"

After half an hour like this, I felt that this strange atmosphere was very uncomfortable, and I wanted to say something to break the silence.

"Shhhh

Ios, however, put his finger to his ear and motioned for me to remain silent.

He lowered his body, crept to the room where Bai Xiang was, and quietly poked his head in to confirm it with his eyes.

After that, he turned back to me and made a reassuring gesture, and cautiously returned to me.

"Let's go, let's go to the council chamber. Try to take your steps as lightly as possible, so as not to wake up Baixiang. ”

Whispering in my ear in an inaudible voice, Ios stood lightly toward the door on the other side.

“……”

I didn't know what Ios was going to do, but out of trust in him, I followed him with the same caution.
