740 Really difficult to accept... (1/2)

Seiji had thought that these crystals were an excellent benefit the system had given him. He'd never expected that they were worth even less than his points.

System: 'Of course it's still a benefit for you, but this is how the price is. Besides, I won't have an upset stomach.' (Picks nose while saying this)

Seiji: 'That was just a small joke, don't hold a grudge over it!'

It was the same for all the [Furniture] options in the system. With the conversion rate of 33:1, it was quite a bad deal.

Seiji wanted to protest, but the system had an absolute monopoly, so protesting would be useless. He could only hope that the ”1 crystal” unit wasn't too much.

He chose the [Bathroom] option and confirmed that he wished to use 12 crystals to construct one for his Spirit House.

A narrow gray crack instantly formed in midair. The crack then opened up into an oval shape that began to glow.

The Inner World Crystals illuminated by the glow swiftly transformed into a dark red liquid that flew into the gray oval!

Seiji could only watch as the crystals everyone gathered after so much hard work disappeared so quickly. He hoped that at least half would still remain.

After only a few seconds, the oval closed itself, and the crack disappeared. The system informed him [Bathroom currently under construction. Completion progress: 0%.]

Seiji felt that the remaining crystals were at an acceptable number.

In total, he had received 37 crystals from ordinary Sakura samurai demons, 26 slightly larger crystals from the Generals, 2 crystals from the Kings, and seven large crystals from the tree demons. The [Bathroom]'s construction of ”12 crystals” used up every single small crystal from the Sakura samurai demons, and a very small portion of one crystal from the tree demons.

Seiji then chose to construct a [Warehouse] for the price of 22 crystals.

The gray crack appeared once more, and absorbed the crystals through its glowing oval.

This time, it absorbed three and a piece of the tree demons' crystals, leaving roughly three and a half tree demon large crystals behind.

Seiji did an approximate calculation and found that there were roughly 25 crystals remaining according to his system's standards. He could construct one more room, exchange for some furniture, or save the crystals for opening the door.

The [Warehouse] was like his personal dimensional storage that he could open up by itself. The price for opening the [Warehouse]'s door was only 8 points, but the crystal cost was the same as the 33 point door opening requirement for the Spirit House, 1 crystal… It was truly such a terrible deal.

Although that was the case, if he could obtain this many crystals with each training session in the Domain, he would be able to upgrade his entire Spirit House after only a few grinding sessions!

Still, he wanted to try.

He didn't ask his knight order members to continue fighting. Instead, he went into the Domain by himself for some grinding.

As a result, he didn't obtain a single crystal after the first wave.

He obtained one crystal after the second wave.

He obtained zero crystals from the third wave.

He obtained two crystals from the fourth wave.

His grand total of crystals obtained: three.

Seiji's cheeks twitched as he looked at the measly three small crystals in his hand. This probably didn't even count for a single crystal according to his system's unit for crystal!

”Do you still want to grind?” Kazuko floated in midair while looking at him.

”No.”

He decided to leave the grinding at that for today.

After Natsuya returned, Seiji told her about what happened and showed her the crystals.

”These are called Inner World Crystals. Soul Society is currently collecting them,” Natsuya told him. ”I've heard that they're an important resource. However, it's considered top-secret what they're used for. My ranking isn't high enough to know about their use.”

”I can guess what they're using these for, because these crystals are highly useful to me as well,” Seiji told her honestly.

Natsuya revealed a surprised expression when she heard this.

Seiji smiled.

”I'm capable of using these crystals to open up an alternate dimension… Basically, a personal Inner World Domain belonging only to me!”

”Your personal Domain…” Natsuya widened her eyes.

”It's different from Kazuko's Domain because my Domain is a safe and stable dimension with no monsters in it at all,” Seiji explained. ”I need as many crystals as possible to upgrade this Domain of mine. I'm guessing that Soul Society requires these crystals to do something similar, which is why these have become an important resource.”

The scion paused in astonishment.

Seiji possessed an alternate dimension Domain… a safe and stable Inner World location with no monsters at all…
