Chapter 514: A Gamble (2/2)

Jin nodded, and had Nurses Alpha and Beta carry Istalis outside of the room using a stretcher.

“I won’t be able to treat her here, so I’ll be taking her to my secret base, where I’ll be better equipped to do this. I’ll be back soon, so there’s no need for you to worry.”

“Yes, I’ll be leaving everything in your hands, Jin.”

“And I’ll make sure to live up to that trust.”

＊　　　＊　　　＊

A hospital bed where Istalis lay was brought to the control room in the basement of Hourai Island.

“She’s all yours, Laojun.”

“Understood. …I will begin now.”

Laojun’s mobile terminal “Laozi” placed its hand over Istalis’ forehead.

“‘Transinfo’… As expected, it has no effect.”

“Hmm, this is going to be rough. Is there anything we can do…?”

Jin started to think.

“Thoughts… Mind… Brain waves… Brain waves? …Laojun, do you have data on the magic that demons have used?”

“Yes, I have information on several of their spells.”

“Check their magical pattern. Especially their frequency.”

“Understood. Comparing data… I see, this…”

“What is it?”

“Their frequency seems to be quite high.”

Jin seemed to be pleased with Laojun’s reply.

“Well, I thought that would be the case, but it seems my guess was right. The demons have an unusually high frequency in their magical patterns. Probably an order of magnitude higher.”

“Well, then it makes sense that they can’t be read by conventional humans.”

“Yeah. Let’s find the most suitable frequency then.”

In order to sample a waveform correctly, it is necessary to sample at a frequency higher than twice the bandwidth of the frequency component of said waveform.

For example, when sampling music on a CD, it needs to be at a frequency of 44.1 kHz to match the human audible frequency of 20 kHz.

In the case of the demons, the frequency of magical power and mental waves was higher than that of humans, so it could not be read correctly by human magic.

Based on this reasoning, Laoujun used “Transinfo” several times to determine the optimum magic power pattern to make it work.

“Understood. I believe we have a good chance to make it work if we do it like this.”

“I see.”

“But when tampering with someone’s memories, we have to be very careful about how far back we should go.”

“We should be able to have a general idea of where to stop by asking Netros. The question is whether we can get it to work with a specific date and time.”

“That shouldn’t be a problem. I have some data on former prisoners, so even if there is an error, it should be within a 1-hour margin.”

Laojun had already erased memory of Count Walter’s plan and how the prisoners of the Inad mine were captured after they were all incapacitated when they tried to attack Kaina Village.

Jin had thought to use that data to help him erase Istalis’ memory all the way back until a little before the moment she was tortured.

“Could you confirm this, My Lord?”

“Sure.”

After his short answer, Jin returned to Nidou Castle to check that with Netros.

＊　　　＊　　　＊

“They were captured on August 4th, right?”

“Yes, I’ve confirmed this with Netros.”

“Then I’ll begin. ‘Amnesia’, August 5th…”

The treatment itself took only a brief moment.

“I will now check what became of her memories using ‘Read Info’.”

“Read Info” is a spell that eliminates the need to transfer information to a Magi Crystal from “Transinfo”. Since information flows in an instant, there is no point in using it unless you have Laojun’s processing power.

“Well, ‘Read Info’ …Alright, the memories from August 4th onward have been completely erased.”

“So it worked, huh…”

Jin felt as if a heavy burden had been taken off his shoulders.

“Alright then, let’s take Istalis back to Nidou Castle.”

＊　　　＊　　　＊

“Jin! Did it work?”

As soon as Jin returned to Nidou Castle, Shion hurried to him.

“Yeah. She may still remember about being captured on August 4th, but she shouldn’t be able to remember anything after that.”

“I wonder if this will help her at all.”

“I don’t know that. But I believe that she won’t be trapped in madness anymore now that she doesn’t have those painful memories.”

The human heart is unfathomable, and the same was true for demons. It was quite possible that things wouldn’t go as planned. However, Jin wanted to bet on Shion’s sister.

“I think she’ll be waking up in less than an hour. Please remain by her side.”

“Got it.”

“Mr. Jin, I have a favor to ask.”

“Hmm?”

Having recovered enough to be able to get up, Netros stopped Jin as he was about to leave.

“Could you… Could you erase my memories as well?”
