Manga Isekai No Sumikko De Kaiteki Monozukuri Seikatsu Megami Sama No Kureta Koubou Wa Chotto Yarisugi Seinou Datta Chapter 4 Exclusive -
The basement door was at the back of the workshop, behind a shelf of failed experimental goo. It was made of dark, petrified wood, etched with a single circle: Goddess’s Crest.
“Okay, system,” I muttered. “Open.”
A holographic prompt appeared:
[Workshop Master Sora Takumi – License Level 10 Confirmed.]
The basement is not a storage room. It is a ‘Second Layer Workshop.’ Access will consume 500 MP and activate emergency safety protocols. Proceed?
[YES] / [NO]
My MP was exactly 520. One wrong step, and I’d collapse.
I pressed [YES].
The floor didn’t open. The door didn’t swing. Instead, the entire workshop shuddered, and the stone floor beneath me descended—like an elevator made of compressed gravity. The walls blurred, and numbers flashed:
Descending: -10m … -50m … -200m …
At -200 meters, it stopped. The air was cool, metallic, and smelled of ozone.
I stood in a circular chamber, about 30 meters in diameter. In the center floated a crystalline sphere, humming with golden light. Around it, four automated crafting stations stood dormant: a Forge, a Loom, a Distillery, and an Enchanter’s Desk.
Then a system message, written in bold red text: The basement door was at the back of
[Warning: Goddess’s ‘Chotto Yarisugi’ Design Detected.]
This basement contains a Core Forge capable of converting raw magic into physical matter. Production speed: 300x normal. Quality floor: S-Rank minimum.
Restriction: Each creation consumes 1 day of user’s lifespan.
I froze. Consumes lifespan?
“That’s not ‘a little too much’—that’s insane!” I shouted.
The crystal pulsed, and a hologram of the goddess—Aurelia, Deity of Crafting—appeared. She was smiling like a mischievous cat.
“Sora-kun! You made it! Surprise~” she chimed. “The basement is my special gift. With it, you can make legendary items in hours instead of years. The lifespan cost? Oh, just one day per item. But don’t worry! If you craft a Longevity Potion (S-Rank), you gain back ten days. So it’s a net positive! Probably.”
“Probably?!”
“Well, you need an S-Rank recipe first. And the ingredients for that are… uh… in the deepest part of the Crimson Labyrinth. Good luck!”
She vanished.
I stared at the Core Forge. This wasn’t a workshop. It was a gacha machine powered by my own life.
The final page of Chapter 4 reveals a teaser for Chapter 5: The Labyrinth’s Heart & The Talking Hammer. Kouki must enter a dungeon, but rather than fighting, he plans to set up a mobile crafting outpost. The title alone promises more yarisugi seinou (overpowered performance) action. [Workshop Master Sora Takumi – License Level 10 Confirmed
Unlike earlier chapters that focused on personal comfort (perfecting coffee brewing, building an auto-sorting bookshelf), Chapter 4 expands the scope. The keyword kaiteki monozukuri seikatsu (comfortable crafting life) is tested. Can Kouki maintain his cozy corner if his creations keep escalating?
The chapter introduces two major long-term arcs:
The chapter ends with Kouki sighing, holding a cup of self-warming tea, and muttering, “So much for a quiet life.”
I spent two hours exploring the basement. The four crafting stations were incredible—the Forge could melt mythril ore in seconds, the Loom could spin spider silk into elemental robes, and the Distillery could age 100-year wine in ten minutes.
But the Core Forge was the true monster.
It offered a menu:
[Available Templates (Level 10)]
I needed the Labyrinth Key to get Longevity ingredients. But 7 days of my life? I was 29. Not old, but not young.
Then I noticed a checkbox at the bottom:
[Use ‘Mana Substitute’ – Convert 10,000 MP instead of 1 day lifespan.] My MP was exactly 520
I had 520 MP.
“Tch. Useless.”
But wait. The Distillery could make Mana Potions (B-Rank) in 10 minutes. If I automated the process…
For the next 12 hours, I set up a loop:
It worked. I lost zero days of life. But my body ached—the mana conversion strained my soul. By the 7th “payment,” my vision blurred and I vomited blue light.
But in my hand: a black iron key, warm like a heartbeat.
[Gate Key: Crimson Labyrinth – First Floor] acquired.
Title: Isekai no Sumikko de Kaiteki Monozukuri Seikatsu: Megami-sama no Kureta Koubou wa Chotto Yarisugi Seinou datta Chapter: 4 Genre: Isekai, Slice of Life, Fantasy, Crafting
In a genre often dominated by harem politics and demon lord slaying, Isekai no Sumikko de Kaiteki Monozukuri Seikatsu (roughly translated as A Comfortable Crafting Life in the Corner of Another World: The Workshop Given by the Goddess Had Functions That Were a Bit Too OP) continues to carve out a cozy niche. Chapter 4 serves as a pivotal turning point for the series, transitioning from pure setup into the tangible rewards of a quiet life well-lived.
The art style in Chapter 4 deserves special mention. Where previous chapters used soft, circular lines to emphasize coziness, Chapter 4 shifts to sharp, mechanical precision during workshop sequences. The double-page spread of the workshop’s blueprint hologram projecting over the forest is breathtaking.
Pacing-wise, the chapter balances:
This keeps the isekai no sumikko (corner of another world) feel intact, even as stakes rise.
