I run a funeral home, I don't know how to teach people how to slay demons

"Monster clan?"

Lu Changsheng moved his eyes to the young man in the cage. He really couldn't see any difference between this young man and a human being.

"Yes, guest! This is just a sea monster captured from the front line. As long as the owner is recognized, even the Demon Slayer Division will recognize his identity. Guests can rest assured."

The shopkeeper wiped the sweat from his forehead. Lu Changsheng looked really scary just now.

"Siren?" Lu Changsheng is no longer a novice who knows nothing. He pays attention to the Guizhai APP almost every day, and naturally has a lot of knowledge about the world of awakeners.

"Aren't all sirens female? Why does he..."

The shopkeeper leaned against the cage, rubbed his hands, and said flatteringly: "Guest, you don't know something. Although most of the sirens are female, there are also a few male sirens, and they are stronger than the female sirens. "More."

"And just like the female siren, she will only recognize one master in her life, and she will never betray her until death."

"This is the last treasure of our store. If you miss it, you don't know when you will see it again!"

Pull it down. Only one of your six cages is left. It wasn't left over by someone else. It's still a treasure.

Lu Changsheng waved his hand indifferently. What's the use of recognizing the master? The system didn't say anything and he couldn't accept this young man as his disciple. It was of no great use.

When Lu Changsheng was about to take Gu Jia away, he found the young man in the cage looking at him for help.

That look in his eyes made Lu Changsheng feel so familiar...

For some reason, he thought of the girl who died alone in front of her parents' grave.

The same eyes, the same despair, the same helplessness.

Gu Jia subconsciously grasped her master's hand, and she felt a severe blockage in her heart.

But I can't understand what that emotion means.

"Sir! I'm not a demon, I'm a human! Please save me!" The boy suddenly shouted loudly.

His body stiffened suddenly.

As if he was suffering tremendous pain, his whole body was shaking uncontrollably, and bursts of blood oozed from the corners of his mouth.

A huge electric current was transmitted along the chain to the young man's body, and within a moment, bursts of green smoke appeared.

Soon, the young man knelt on the ground motionless and stopped making a sound.

"What does this mean?" Lu Changsheng's expression suddenly changed.

He drew the Ten Thousand God Sword with one hand and pointed it at the shop owner. If he said a wrong word, he would be beheaded on the spot.

The shop owner was so frightened that he took a few steps back, waved his hands and begged for mercy, "Guest, don't believe his nonsense, he is a monster!"

"The Siren is the best at lying. Don't let him fool you!"

Seeing that Lu Changsheng's eyes were still cold, the fat shopkeeper became anxious and pointed at the cage and said, "Guest, look at it, how can a normal human being survive after being exposed to high-voltage electricity?"

"Only the monster clan's powerful body can withstand it!"

Lu Changsheng glanced towards the cage. Although the boy's breath was weak, he was indeed not dead yet.

Lu Changsheng's expression was uncertain, as if he was struggling with something.

There was silence for a long time.

He dismissed the Ten Thousand God Sword, stared at the shop owner, and said coldly, "How much does it cost?"

"Ah..." The shop owner was a little confused and didn't react for a moment.

"I said, how much does this child cost?"

"100...100 fourth-order crystal nuclei..." the shopkeeper stuttered, "or...the equivalent fifth-order crystal nuclei, sixth-order crystal nuclei, all are accepted."

"How much did you say?" Lu Changsheng approached the shop owner step by step, staring at him with unkind eyes.

The shop owner swallowed, and cold sweat slid down his forehead. He felt like he was being stared at by a ferocious beast, and his heart was beating fast.

"50...50 pieces, guest, this price is very reasonable..."

"You've been so electrified, how can you still call it real?" Lu Changsheng tilted his head and stared at the shopkeeper, and said word by word, "With 10 crystal cores, I will give you two more high-end packages from Changshengtang."

"Chang Sheng Tang is a century-old store. If you don't have connections, you won't be able to buy it."

"How about it?"

"No, how can you bargain like this?" The shop owner was confused. He had never heard of this "century-old store". "Chang Sheng Tang? What is it? A luxury store?"

Lu Changsheng calmly drew out the Ten Thousand God Sword, rubbed it on his sleeve, and lightly licked his lips with the tip of his tongue, as if he would kill anyone if he disagreed with him.

Gu Jia also cooperated and put on a fierce expression on the side, with her little nose turned up and her teeth bared.

The shop owner's hair stood on end, and his scalp felt numb.

The look in Lu Changsheng's eyes was really terrifying, and the sea monster in the cage was indeed only half-lived. Although the shop owner was in pain, he still had to agree.

"Here, and here."

"Well, I still have this, just sign it here."

Lu Changsheng signed one document after another under the command of the fat shopkeeper. Most of them are the identity information of the Demon Slayer Division, as well as bloodline certificates.

"That's it." Lu Changsheng finished signing the last document, clapped his hands, and walked to the iron cage on his own.

"Guest! Wait, you haven't recognized your master yet! According to the rules of the Demon Slayer Division, a sea monster that has not recognized its master cannot come out of the iron cage."

"Hurry up, that kid is almost out of breath, and you won't even be able to sell 10 crystal cores in a while!" Lu Changsheng urged unhappily.

"Customer, please give me some blood. The siren needs to drink the blood of the master voluntarily to recognize the master. It's very simple." The fat shopkeeper took out a small box from behind the counter and motioned Lu Changsheng to come to the counter.

Lu Changsheng rolled up his sleeves, took out the cuff from his pocket, and tied it to his arm skillfully, holding one end in his mouth and wrapping the other end with his hand.

Wrapping, knotting, holding it in his mouth and lifting it up, the whole set of movements was done in one go, without any delay.

The fat shopkeeper looked at Lu Changsheng's outstretched arm and was stunned.

No, what does this customer do...

Why is he so skilled...

"Don't stand there, draw it!" Lu Changsheng frowned slightly. This shopkeeper is too amateur.

"Oh... Oh, customer, you misunderstood. It doesn't take so much. Just a few drops will do." The fat shopkeeper hurriedly took out the tools from the box.

He gently poked Lu Changsheng's finger and took out a few drops of blood.

The boy's breathing was very weak, and he could only see the appearance of his "master" with the corner of his eyes.

He took the blood handed by the shopkeeper tremblingly.

The boy put it in his mouth without any hesitation, bit the test paper containing blood, and swallowed it in one gulp.

A will descended from the sky and descended into the boy's mind. He could not resist it at all, and his cognition was modified in an instant.

The person outside the cage was no longer a strange man, but his sky. There was nothing more important than the master in this world.

The fat shopkeeper took out the tools and did the same on the boy's hand, taking out a few drops of blood.

Seeing the bright red blood on the test paper, the fat shopkeeper opened the iron cage with confidence, untied the iron chain on the boy's neck, and made a "please" gesture to Lu Changsheng.

Lu Changsheng was not in a hurry to bring the boy out, but turned around and whispered to Gu Jia, "Jia'er, take this child back to Changsheng Hall first, and ask Sister Hongye to come over and take a look and treat his injuries."

"Master will be back a little later."

Gu Jia nodded gently, followed the master to help the boy out of the iron cage and left the black market.

The fat shop owner saw that the scary customer finally walked away and breathed a long sigh of relief.

Although the price of this one was very low, at least this batch of sea monsters was sold out. He said he would have a good meal tonight to reward himself.

While thinking about it, the shop owner was not idle. He quickly closed the door of the shop and walked slowly towards the door of the black market.

In the entire black market, no one noticed that a figure was moving slowly with the fat shop owner, like a ghost...
