A few days had passed since [Ethereal Knights] and Liliane died.

On the day of the incident, my parents were busy hearing rumors and leaving the job to their buddies to come home and attend Mr. Liliane's funeral.

With that said, your brother was also at Liliane's funeral. Your brother had never seen it before, but the story seemed like he was going to a school teaching lords, company management, etc. in another city.

A receptionist at the Adventurer Counter told me that the Episcopal Church had begun a full investigation to find out what caused the supergravity field.

It seems that the scale of the case is no longer within the scope of the adventurer, so it is advisable for me to regain my mind and ask for an intermediate class, but I have stopped accepting the request because it is impossible to sort out my mind that Mr. Liliane will die.

Instead, I was about to consult with Mr Cecilia to study whether measures could be taken because a similar incident might occur again.

That ultra-gravity field was dangerous to the point where even your father remained in doubt as to whether he could stand it.

I don't know the details because I'm not a researcher in my previous life, but I was guessing it might be a small black hole.

If that's the case, I think we need to create a [magic guide] that will allow us to make an emergency exit the moment we sense the supergravity field.

Like myself and Cecilia, I thought that if [crystal metastases] could act on the population, they could move from party to party to safety zone.

I still don't know the principle of metastasis, but I felt that I was using it because I could use it. Time attributes are a lot of mysteries...

Even if we were to do experiments, they were going to consume a lot of [rainbow crystals] related to metastases, so they didn't have enough money.

Then one morning, a few more days later, Maria came to visit me in a carriage at home.

I didn't assume that Maria would come directly to my home, and I was normally in the middle of breakfast for the three of us, but I headed to the reception room where I was waiting for Maria with Cecilia alone.

Looks like Maria brought in one of the men as an escort, and the man had some kind of big, heavy looking box.

"To Mr. Ray, Mr. Cecilia. Long time no see. Sorry for the sudden visit this morning. I had a rush case and there was something Ray wanted me to see.

"That has to do with the box the man in the back has, doesn't it?

"That's right. And Mr. Ray is witnessing an incident in the cave of an anti-ecclesiastical organization, isn't he?

"Yes. Sure, we [the Eternal Ring] were there at the request...

Do you want to hear more about the case? But then there's no need for Maria to bother coming, and I don't know the relevance of the box a man has.

"Actually, a lot of people witnessed black domed objects that occurred during that incident, but only the Rays testified that it was a supergravity field.

"Well, then, did you still want to hear more about the case from us?

"I'd rather have Mr. Ray see this than that.

The man behind took out a black sphere about 50 cm from the box on his desk. And when the man put the ball down, he left the room. I wonder if it's a secret story for men. I only have a bad feeling...

"Mr. Ray, you may [appraise] or touch it.

I tried [appraisal] as Maria told me, and I came out with [supergravity core]. [Appraisal] In more detail, the inside of the purple sphere was surprisingly filled with precision machines that had become commonplace in previous life.

Ever since I came to this world, I've seen [magic props] utilizing demonic stones, but I've never seen a machine that works with complete electricity.

"Again, Mr. Ray has seen something similar to this...

Was it on your face again?

"It's similar when it comes to similarities, but what's inside was just something I was used to seeing in my previous life.

I was somewhat familiar with machines as well, but that was partly because I was purchasing knowledge online and in books.

"Really...... This is what is classified as an [ancient weapon] in the Episcopal Church, and I also wanted to ask Mr. Ray his opinion on whether it would be good to destroy this.
