Chapter 320

After asking this question, Luo En felt an unusual flicker of unease and tension inside him.

【Ding! Based on the host's previous check-in traces, the coordinate of the dimension where the One Piece world resides has been locked. After calculation, there are now three methods for the host to return to the One Piece world.】

"Three methods?! Great!"

Luo En's face lit up with delight: "Quick, tell me!"

【Method One: The host uses his own strength to shatter the dimensional wall, physically crossing the temporal vortex. The system can guide the host to the outer dimensional membrane of the One Piece world via coordinates; once there, the host merely needs to break through the One Piece world's dimensional membrane to return.】

Luo En's expression darkened: "How am I supposed to shatter a dimensional wall and cross a temporal vortex with my bare body? And how long would it take to reach that level of power in this world?!"

【Method Two: Provide a large amount of temporal-spatial energy. The upgraded system can teleport the host back to any previously checked-in location across worlds.】

"This method sounds good, but where in this world am I supposed to find a large amount of dimensional energy for you?"

【Method Three: Spend the corresponding check-in points. The upgraded system can teleport the host to an adjacent alternate world.】

"Check-in points… what are those?"

【Each time the host checks in, it counts as one check-in point. Current check-in points: 1.】

"What about all the times I checked in back in the One Piece world?"

【Check-in points are a product of the system's upgrade. Now, only 10 check-in points are needed to teleport the host to an adjacent alternate world.】

Luo En rubbed his forehead, speechless: "If you teleport me to an adjacent alternate world, how do I get back to the One Piece world?"

He felt a pang of despair—would he never be able to return?

【Rest assured, host. Based on the system's analysis of the One Piece world's dimensional coordinates, the One Piece world is separated from your current Demon Slayer world by only one adjacent world.】

Hearing the system's mechanical voice say this.

Luo En blinked in surprise: "So if I just pass through one more world, I can return to the One Piece world?!"

【Yes.】

Luo En's eyes instantly brightened, his expression lifting with renewed energy.

"Good!"

30, check-in, Shunpo, current stats

The system has completed its upgrade. The system space is now accessible.

Luo En took out a large chunk of meat from a Sea King and roasted it in the small courtyard, replacing the liquor from his endless flask with bubble wine from the Shichibukai Islands.

Eating roasted meat from another world and drinking fine wine from another world, Luo En finally felt the sense of traveling across dimensions.

"System, besides adding check-in points, have you gained any other functions after upgrading?"

Luo En asked.

【In response, host, after the upgrade, the system has added a map check-in feature tailored to different worlds, and the probability of receiving generous rewards upon check-in has also increased.】

"Map check-in?"

Luo En was curious.

【Exactly like this.】

As the system's mechanical voice ended.

A holographic screen appeared before Luo En, displaying a flat map of the Demon Slayer world, with a blinking red dot and numerous blue inverted triangle markers indicating check-in locations, each labeled with a region's name.

【Demon Slayer Corps Headquarters】

【Butterfly House】

【Village of the Swordsmiths】

【Asakusa, Tokyo Prefecture】

【Higurashi Mountain】

【Demon's House】

【Yoshiwara Pleasure District】

【Infinity Train】

【Mount Fujikasane】

【Naraku Spider Mountain】

【Purple Wisteria Clan】

【Infinity Castle】

……

【Ding! The red dot represents your current location. The blue inverted triangle regions around it represent check-in locations.】

Luo En nodded at the holographic screen: "I see. It's indeed more convenient than before."

He scanned the map—if he checked in at all these locations in Nihon, he could gather roughly 15.6 check-in points.

"Time to get moving."

Luo En quickly finished the roasted meat, drained the bubble wine, stood up, and strapped the Nichirin Blade to his waist.

After leaving a note, Luo En's azure eyes flashed with brilliant light, and his figure vanished instantly from the courtyard.

The space above the Butterfly House's roof rippled like water.

The next second.

Luo En materialized out of thin air—dressed in black, his long hair tied into a high ponytail, a vintage sword at his waist, his figure tall and upright.

【Ding! Detecting host location—Butterfly House. Check-in available. Proceed with check-in?】

"Check-in."

【Check-in complete. Reward obtained—Vitality +10, Spirit Power +10.】

Reward obtained—Healing Technique upgraded to Great Healing Technique. Current level: Lv1.

Reward obtained—1 check-in point. Current check-in points: 2.】

"Has the probability of receiving rich rewards increased... good."

Luo En nodded slightly, quite satisfied.

Shinazugawa Aoi, who was drying quilts in the courtyard, seemed to sense something.

She turned her head to look up at the roof ridge of the Butterfly House.

But she saw nothing.

Using the Transcendental Eye technique to perform spatial transfer.

Luo En, having left the Butterfly House, appeared instantly in the Village of Swordsmiths.

【Ding, detecting host location—Village of Swordsmiths, sign-in condition met, sign in?】

Standing on a tree branch, Luo En gazed down at Kotoha, who was still deeply absorbed in studying the Zero-Type Origin, and silently murmured: "Sign in."

【Ding, sign-in complete, received sign-in reward—Vitality +10, Mental Power +10.】

Received sign-in reward—Forging Art.

Received 1 sign-in point, current sign-in points: 3.】

After completing the sign-in.

Luo En vanished instantly from his spot, leaving the Village of Swordsmiths.

No one noticed he had ever been here.

After leaving the Demon Slayer Corps headquarters, Luo En activated the abilities of the Puff-Puff Fruit, shooting skyward at incredible speed toward the nearest sign-in location.

Signed in at Asakusa, Tokyo Prefecture, received Vitality +10, Mental Power +10.

Signed in at Fujikasane Mountain, received Vitality +10, Mental Power +10, Demon Poison Antidote x1, Antidote x1.

Signed in at the Purple Wisteria Clan, received Vitality +10, Mental Power +10.

Signed in at the Demon's House, received Vitality +10, Mental Power +10.

……

Samae Mountain.

Takanori Saigyouji, wearing a mask, carried firewood as he walked toward home.

He gazed at the sky, troubled.

"Tanjiro, and Nezuko, are you both well?"

As he passed the massive rock split open by Tanjiro.

Takanori Saigyouji instantly spotted a tall, slender figure standing before the rock; his heart leapt, and he sniffed the air.

Not the scent of a demon—definitely human…

His unease eased slightly, and he spoke to the figure: "Who are you…?"
