"By the way System, if Merlin really exists. Does the Fate Grand Order really exist?"

[Of course. Otherwise I won't tell you about the servant summoning ritual. And regarding the Merlin body you used. I have several possibilities. Want to hear it?"

Yoru nodded his head.

[First, Origin made something similar. So this isn't Merlin's body, but one made by Origin and resembles Merlin.]

"But why did he make everything similar down to the details of potential and hidden status?"

[Second.]

"You don't know the reason?"

[Secondly, Origin made a contract with Merlin. Merlin lent his body to get something that Origin had. For the thing that Merlin want, I don't know.]

"Then it's a loss for Origin. Even though he has and can make anything. It's to good to be true for him to give someone something just for something like this. The first reason is more believable to me."

[Third, Merlin has died and Origin picked up his body.]

"You think Merlin's body just lay in the side road. After all, it's not like Merlin can't..."

Yoru was silent...

And after a few minutes, he started talking.

"Garden of Avalon indeed cannot be destroyed because that place has no connection with anything that exists outside it. However, if the universe itself is destroyed. The Garden of Avalon must also be destroyed. Maybe in an alternate universe. Chaldea can't stop the destruction of mankind and that's why Origin was able to obtain Merlin's body."

[Possible. But, the truth is known only to Origin and Merlin.]

"But if this body is indeed Merlin's body, and has the same potential as Merlin. Maybe I can improve my sword skills, because Merlin is the swordmanship instructor of King Arthur. And Merlin's magic abilities are practically as good as Solomon and Gilgamesh."

[When we talk about potential, you are indeed not wrong. But have you forgotten about my existence. With me here, I can turn stones into gold and even diamonds. So, if you are condescending to say that you have potential on par with Solomon and Gilgamesh. That means you are insulting me.]

"Ah... Sorry, you're trying to make me a God aren't you?"

[Not just God, but a True God.]

"Hey, hey, I get it. And back to the matter. I still don't like this whole thing."

[Huhf, but with what has happened, hasn't everything been proven]

"I thought everything would be over once I got all my memories. But in the end, I'm just Origin's "Errand Boy."

[Do we have another choice]

A case of literary theft: this tale is not rightfully on Amazon; if you see it, report the violation.

"That's what makes me dislike all of this even more."

Yoru looked furious at what he found out.

He was so angry that in the end he couldn't finish what he wanted to finish. And finally he chose to leave the Hyperbolic Time Chamber.

After exiting the building, Yoru then flew a little higher and looked around him. Yoru then uses the magic he has to change the area around Mochizuki General Hospital to make their defense easier.

Yoru didn't forget about the barrier, and made the barrier stronger so the Bishop couldn't change anything.

"System, can you scan the map better now?"

[What do you want]

"How far can you use scanning?"

[Do you want me to look for mines or something]

"No, I was just wondering if you could find where Atlantis is."

[huh]

System sounded slightly surprised and couldn't believe what he was hearing.

[Are you seriously asking something like that]

"Can you do it? Maybe there is a lot of treasure there?"

[Huhf, I don't know why you can think like that. But Atlantis doesn't exist. Not in this world I mean.]

"Ehhh... That's a same."

[If you want treasure. I have several places where cargo ships sunk.]

"Are there many?"

[Not much, maybe only worth some of billions of dollars]

Yoru immediately stopped everything he was doing and froze in place.

[Why, to little right]

"LITTLE YOUR ASS!!! BILLION DOLLARS YOU SAY LITTLE!!!"

Huhf, huhf, huhf, huhf...

Yoru looked out of breath after screaming at the top of his lungs.

[How. You want to know]

"Pin everything!!! Let's go and search for the treasure!!!"

[But better tell Saeko and the others. We need a little more time here.]

Yoru quickly found Saeko and the other and told them what he wanted to do. Saeko was actually hoping to come along. But when Yoru said that there would be no danger at all, and it would be better to train to get stronger. Saeko relents and doesn't come along.

After that, Yoru asked the group including Souichiro, Tadashi, Yuriko, Takashi and Yuusuke to leave. After they left, Yoru quickly explained what they should do.

Yoru explained that inside the building has a different time speed than outside the building. He told me that the time difference that occurred was 1 minutes outside the building equals to 8 minutes inside the building. So 4 hours inside the building equals half an hour outside.

They didn't believe what Yoru said, but when Yoru showed what happened when Yoru threw a bottle outside the building and the bottle fell slowly and finally hit the ground and broke, they just shocked and nodded their head.

"So, I'm asking you to arrange a training schedule for everyone here. Make sure everyone take a breaks after 8 hours have passed. After that, exit the building and rest for half an hour or an hour. Then enter again for 8 hours and repeat this process until later at night or until I come back. Do you understand?"

Everyone nodded their heads.

After Yoru was done with what he needed to do. He immediately flew to the point that the system had prepared on the map.

Of course Yoru used his magic as hard as he could. He even used space and time magic so he could get to the prepared place more quickly.

"System, this is Indonesia right?"

[Yes, is there a problem]

"Not really, I do know that the Indonesian seas are used as trade routes. But are there lots of treasures at the bottom of the sea?"

[I don't know how many there are. But, I think that's quite a lot. Because what sank were merchant ships and ships laden with loot and so on.]

"Ah... It's still in the 2000s. So the colonial period hasn't passed long ago. So not all ships like that have been found and pulled out yet."

[Right. I also found some in the seas of other countries. However, there's more in here]

"In that case, I don't need to be shy. Let's take everything we can find."

The process of taking underwater treasures is not easy. Even though Yoru can use magic, and he is a High Human, he is still a "Human", so he still needs to breathe. And swimming cannot be as fast as walking on land or fly in the air.

Finally Yoru decided to make a 10 meter barrier with him as the center and finally he walked on the seabed like he was walking on normal land.

It's true what System said Yoru found a lot of things there. From gold coins, gold glasses, gold cups, diamonds and many more.

"System, can I exchange historical objects for more points?"

[Not really. The system does not care about the historical value of an item. So whatever story behind an object is not important to the system]

"But can you tell the difference between historical and non-historical things? Maybe if we find something historic we can sell it to the government or to the black market."

[That is true. Then just take them all. Let me separate everything later]

"Yes captain!"

Yoru gave a salute that made System laugh.

After that, Yoru took all the things that he thought were valuable, whether they were historical objects or not. System also sometimes directs Yoru to take certain items.

After 6 hours of searching for treasure. Yoru decided to end his quest for today.

[It's already 4 o'clock. We still have to prepare for an attack]

Yoru who heard System's words immediately stopped looking for treasure and rushed back to Mochizuki General Hospital.

"I didn't expect we would find so many items just now."

[But we can't take all of them yet]

"We'll continue tomorrow. We are now focused on the zombies that will attack now."

[But, we didn't get any notification about today's attack. It's possible that they won't attack today]

"If they really don't attack, we can use our time to train everyone without leaving the building."

[I suggest you don't do it. They still need to come out every 8 or 12 hours at least. Because their metabolism will be disrupted if they stay in the Time Chamber for too long]

"What's the problem though? We can heal everything using healing magic right? We can use this problem as a way to train Shizuka and Megumi." Yoru answered with a slightly uncomprehending face.

[The problem is not their physical health, but their mental health. Instability of lifestyle will disturb them mentally. So, don't push them too hard.]

"What about Saeko and the others. Will they also be in trouble?" Yoru looked worried.

[Of course. They're only human. Even you yourself will be troubled if you push yourself too hard]

After hearing all that, Yoru immediately rushed back to Mochizuki General Hospital at full speed.
