Chapter 1

At Sagiriyama, a young man who looked no more than sixteen or seventeen years old kept swinging the long sword in his hand.

"……997, 998, 999, 1000."

The boy wiped the sweat from his forehead. At this moment, a man wearing a Tengu mask appeared beside them silently.

"Lin Guang, I heard someone is missing near the foot of the mountain. It might be a ghost. Come with me."

"Yes, Grandpa Urokodaki."

Lin Guang put away the knife in his hand and followed behind Urokodaki Sakonji, with a myriad of thoughts in his mind.

"Yesterday, Brother Giyuu sent a message saying that he hopes Grandpa Urokodaki will train a boy with a ghost to become a swordsman who kills ghosts. It seems that the plot has already begun."

"My system can finally be activated."

That's right, Lin Guang's soul is not from this world, but from a otaku on Blue Star.

Because he often stayed up late to watch anime and play games, he eventually died suddenly at home, but his soul was reborn as an abandoned baby in the world of Demon Slayer.

Later, he was picked up and adopted by Urokodaki Sakonji, and when Lin Guang saw Urokodaki Sakonji's Tengu mask, he knew that he had traveled to the world of Demon Slayer.

When Lin Guang traveled to this world, he had already bound the traveler's golden finger, but he needed to meet one condition to activate it.

That is to kill a demon in front of Tanjiro.

"We're here."

The voice of Urokodaki Sakonji brought Lin Guang back to his senses.

Following Urokodaki Sakonji's gaze, Lin Guang saw the faint light emanating from the ancestral hall in the distance.

When he got closer to the ancestral hall, he saw the light of the ancestral hall suddenly disappear, and then two figures flew out of the ancestral hall. The young man in a plaid shirt swung the axe in his hand and directly cut the demon's neck, forcing the demon to retreat.

Seeing this figure, Lin Guang knew that his guess was correct,"It's Tanjiro Kamado, so Nezuko should be nearby too."

Urokodaki Sakonji saw Tanjiro being strangled by the demon, and was about to attack.

Suddenly Nezuko appeared beside Tanjiro and kicked the demon's head away.

Seeing this scene, Urokodaki Sakonji also thought of Tomioka Giyu's letter.

"Is it the boy with a ghost mentioned in the letter of Giyuu?"

At this time, the headless ghost body and Nezuko started fighting, and the fallen ghost head also grew arms to entangle Tanjiro.

Urokodaki did not make a move, but Lin Guang could no longer bear it. This was the best time for him to activate the system.

Lin Guang opened his mouth slightly and took a breath into his body.

""Water Breathing! Type 4! Strike Tide!"

Blue water splashed out from the blade, cutting the demon's body in half, making it unable to move. The demon's head also lost consciousness due to the death of his body.

Tanjiro let go of the axe, and the axe fell to the ground, just binding the demon's head to the ground.

At this time, Tanjiro's voice rang in Lin Guang's ears.

"you...Are you a member of the Demon Slayer Corps?"

Lin Guang shook his head,"My name is Lin Guang. I am not a member of the Demon Slayer Corps yet, but one day I will join the Demon Slayer Corps."

Tanjiro said,"My name is Tanjiro, and this is my sister Nezuko. I believe you can definitely join the Demon Slayer Corps."

"Thank you, but let's get rid of the ghost first."Lin Guang walked towards the ghost head with hands on the ground.

At this time, the unconscious ghost woke up.

"What happened just now? Why did the body suddenly die?"

When the ghost saw Lin Guang beside Tanjiro, he immediately yelled

"Hey! It was you, little ghost, who killed my body! Come here quickly, I want to eat you!"

Lin Guang drew out the Sun Wheel Sword and cut off the ghost's neck with one knife,"I hope you won't become a ghost again in your next life."

""Ah!"

A shrill cry broke through the sky.

In the cry, the ghost dissipated in the air.

An intelligent voice sounded in Lin Guang's mind.

【The host kills the ordinary ghost, and the treasure chest system of the world has been activated】

【Current World - Demon Slayer】

【Every time the host kills a ghost, there is a certain chance that a treasure chest will pop up.】

【System Activation Reward: 1 Novice Treasure Box. 】

Lin Guang smiled slightly,"It's finally activated."

Tanjiro saw this incredible scene, took a step back with his mouth open, his face full of horror.

"Well done."

A man wearing a Tengu mask appeared beside them silently.

"You have mastered the breathing method thoroughly. You did a great job facing the ghost without any hesitation."

After hearing the voice of Urokodaki Sakonji, Lin Guang's mind withdrew from the system.

"Grandpa Urokodaki." Lin Guang smiled slightly, and then stood behind Urokodaki Sakonji.

Then, Urokodaki Sakonji looked at Tanjiro who was standing beside him.

"I am Urokodaki Sakonji. You are the one that Tomioka Giyuu introduced, right?"

Hearing Lin Guang addressing Urokodaki Sakonji, Tanjiro suddenly became nervous.

"ah...It's me, my name is Tanjiro Kamado, and my sister is Nezuko."

Urokodaki Sakonji's tone suddenly became stern:"Tanjiro, what will you do when your sister eats people?"

Tanjiro was stunned for a moment.

Seeing Tanjiro's look, Urokodaki Sakonji was a little disappointed, but Lin Guang suddenly said to himself:"I will kill her with my own hands, and then commit suicide to make an apology."

Hearing Lin Guang's words, Urokodaki was very relieved.
