In Sagiriyama, a young man who looked no older than sixteen or seventeen 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 him silently.
"Lin Guang, I heard that 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 sword in his hand and followed Urokodaki Sakonji, a multitude of thoughts running through his mind.
"Yesterday, Brother Giyuu sent a message saying that he hopes Grandpa Urokodaki will train a boy with a demon to become a demon-slaying swordsman. It seems that the story has already begun."
"My system can finally be activated."
That's right, Lin Guang's soul is not from this world, but from an otaku of the Blue Star.
Because he often stayed up late watching anime and playing video games, he eventually died suddenly at home, but his soul was reborn as an abandoned baby in the Demon Slayer world.
Afterwards, 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 Demon Slayer world.
When Lin Guang came to this world, he had already bound his "Traveler's Golden Finger", but he needed to fulfill a condition to activate it.
That condition was to kill a demon in front of Tanjiro.
"We're here."
Urokodaki Sakonji's voice 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.
As he approached the ancestral hall, he saw the light suddenly disappear, and then two figures flew out of the hall. The young man in the plaid shirt brandished the axe in his hand and directly slashed at the demon's neck, forcing it to retreat.
Seeing this figure, Lin Guang knew that his guess was correct, "It's Tanjiro Kamado, so Nezuko should be nearby as well."
Urokodaki Sakonji saw that Tanjiro was being strangled by the demon and was about to attack.
Suddenly, Nezuko appeared next to Tanjiro and kicked the demon in the head.
Seeing this scene, Urokodaki Sakonji also thought of Tomioka Giyuu's letter.
"Is he the boy with a demon that Giyuu's letter talked about?"
At this moment, the demon's headless body and Nezuko began to fight, and the demon's head, which had fallen, also grew arms to catch Tanjiro.
Urokodaki did not intervene, but Lin Guang could no longer bear it. It was the best time to activate the system.
Lin Guang slightly opened his mouth and took a breath.
"Water Breathing! Fourth Form! Striking Tide!"
Blue water splashed from the sword, cutting the demon's body in half and immobilizing it. The demon's head also lost consciousness due to the death of its body.
Tanjiro dropped the axe, which fell to the ground and grabbed the demon's head.
At this moment, Tanjiro's voice echoed in Lin Guang's ears.
"You… are you a member of the Demon Extermination Corps?"
Lin Guang shook his head. "My name is Lin Guang. I'm not a member of the Demon Extermination Corps yet, but I will be one someday."
Tanjiro said, "My name is Tanjiro, and this is my sister Nezuko. I think you can definitely join the Demon Extermination Corps."
"Thank you, but let's finish off the demon first." Lin Guang walked over to the demon head on the ground.
At this moment, the unconscious demon woke up.
"What happened? Why did the body suddenly die?"
When the demon saw Lin Guang beside Tanjiro, he immediately screamed.
"Hey! It was you, little human, who killed my body! Come here quickly, I want to eat you!"
Lin Guang unsheathed the Nichirin Sword and cut off the demon's neck in one blow. "I hope that in your next life, you won't become a demon."
"Ah!"
A sharp scream broke the silence of the night.
With the scream, the demon vanished into thin air.
An intelligent voice sounded in Lin Guang's mind.
[The host kills the common demon and the world's treasure chest system has been activated.]
[Current World – Demon Slayer]
[Every time the host kills a demon, there is a certain chance that a treasure chest will appear.]
[System Activation Reward: 1 Beginner Treasure Box.]
Lin Guang smiled lightly. "It's finally activated."
Tanjiro saw this unbelievable scene, he took a step back with his mouth open and his face full of horror.
"Good job."
A man wearing a Tengu mask appeared beside him silently.
"You have mastered the breathing method well. You did a great job facing the demon without hesitation."
Hearing Urokodaki Sakonji's voice, Lin Guang's mind withdrew from the system.
"Grandpa Urokodaki." Lin Guang smiled lightly and then stood behind Urokodaki Sakonji.
Then, Urokodaki Sakonji looked at Tanjiro, who was standing next to him.
"I'm Urokodaki Sakonji. You're the one Tomioka Giyuu recommended, right?"
Hearing Lin Guang call Urokodaki Sakonji, Tanjiro suddenly became nervous.
"Ah... yes, it's me. My name is Tanjiro Kamado, and my sister is Nezuko."
Urokodaki Sakonji's tone became stern. "Tanjiro, what will you do when your sister eats people?"
Tanjiro was stunned for a moment.
Seeing Tanjiro's expression, Urokodaki Sakonji felt a little disappointed, but Lin Guang suddenly said to himself, "I'll kill her with my own hands and then commit suicide as an apology."
Hearing Lin Guang's words, Urokodaki felt greatly relieved.
