My sister is Luna

"Third Brother!" the woman named Li Yi exclaimed in surprise. She knew she had been saved.

The person who attacked Niu Dazhuang was an ordinary-looking black-haired man with blood-red eyes that symbolized his vampire identity. He had pale skin and looked sickly.

At this moment, he pulled Li Yi behind him, bared his sharp teeth, and looked at Niu Dazhuang and the others with a fierce gaze. He was ready to fight to the death.

Another vampire. It seems to be that vampire woman's companion. Its aura is almost identical to that woman's, giving off a freshly baked feeling. And I feel like I've seen this person's face somewhere before.

Cain leaned against the window, stroking his chin as he thought. He lowered his hand, which had been secretly gathering strength; he no longer needed to act.

The appearance of another person, a variable, and a witness threw them off balance. As long as Niu Dazhuang and his two companions still held the Xuan Yong Law in high esteem, they would not continue their violent acts once they calmed down as if doused with cold water.

Niu Dazhuang wanted to kill even more vampires, so why would he stop here? As long as he survives, he can always find another opportunity. He can't afford to be defeated here.

"Come on, we'll be back! Just you wait!"

Niu Dazhuang clutched his bleeding head, glared hatefully at Cain and the vampire man, uttered a harsh threat, and ran away with the other two, displaying the classic pathetic act of a minor villain.

"Third Brother, where did you go? I'm so scared I'll never see you again... Waaah..." Seeing that the crisis had passed, Li Yi breathed a sigh of relief and threw herself into the man's arms, sobbing.

"It's alright now. I'm sorry I couldn't protect you properly..." the man said, gently stroking Li Yi's head.

"Hmm..." After calming down a bit, Li Yi stopped crying, but her expression suddenly changed when she looked at the man.

"Why, why did you become like this?!" She frantically touched his face, sniffed his scent, and asked incredulously.

The man didn't answer, but turned to look at Cain by the upstairs window and said:

"Brother, thank you for saving me. I will definitely repay this kindness in the future."

"You've gone too far. I just couldn't stand seeing a few grown men bullying a woman, so I made some sarcastic remarks. Besides, I didn't do anything substantial; I was just an indifferent bystander."

Cain smiled and said that he felt the man's gaze seemed familiar, and he also felt that the man looked somewhat familiar.

"I will repay kindness with gratitude. We'll meet again someday."

After saying that, the man pulled Li Yi away, as if intentionally avoiding Cain and unwilling to communicate with him any further, and soon disappeared into the narrow alley.

Cain watched the two of them walk away, then jumped out of the window and hung far behind them.

……

This is a slum, which, as the name suggests, is an area where poor people live together. It is located on the edge of Xuanyong and is scattered around.

The man led Li Yi into a dilapidated house. Although the exterior was run-down, the interior was clean and tidy.

"Third Brother, there are no other outsiders now. Tell me quickly, why did you become a vampire? Who shares your blood? You could die if you're not careful!"

"That Western-looking man is no ordinary person. His name is Cain. I fought him in Chang'an and lost in one move. He is a powerful expert. Although I don't know why he is here, it's still better to be on guard."

The man looked around outside the door to make sure he found nothing unusual before closing the door and going back inside.

Little did they know, just after the door closed, Cain, who had caught up, leaned against the door, concealing his presence and listening quietly.

"Tell me quickly why you became a vampire, and who exchanged blood with you!" Seeing that the man did not answer her question, Li Yi became a little anxious.

"Of course it's to be with you. Now we're the same kind of people, so there's no need to reject me anymore," the man said affectionately, embracing Li Yi tightly.

“…” Li Yi was stunned.

Did they become vampires for love? And what he just said about blood exchange—is that a way vampires transform into humans? Does it involve using vampire blood to mutate the other person's genes and turn them into a vampire, or…?

Cain leaned against the door, deep in thought, but before he could finish, a roar echoed from inside the room.

"Zhang San, you big idiot!"

Coming to his senses, Li Yi broke free from Zhang San's embrace and angrily pounded his chest. Just because of this, he had ruined his promising future and become a vampire to suffer alongside him. Li Yi truly felt sorry for him and was furious.

"Idiot, moron, you big idiot! You didn't have to go to this lengths for me! Waaaaah..." As she hit him, Li Yi started crying again.

Zhang San? Oh, I see! No wonder he looked familiar.

Cain, who was eavesdropping outside, suddenly realized what was going on.

Zhang San and Kai had met once before; they were rivals on the Chang'an arena. After their battle on the arena, they never expected to meet here.

Zhang San actually became a vampire. Was it for that vampire named Li Yi?

Who turned him into a vampire? Was it someone like Wang Wu?

Upon considering this possibility, Cain decided to follow Zhang San and investigate.

"Why did you go to such lengths for me?" Li Yi questioned.

"Because I love you. You once rejected my love because of our different races, but this time we are the same kind. You don't need to care about worldly opinions anymore. It's only natural for two vampires to be together..."

Zhang San said with deep emotion that when he saw Li Yi, who had never changed even in the midst of suffering and who held fast to the goodness in her heart, he knew that this was the person he was meant to protect for the rest of his life.

"Third brother, I'm sorry, it's all my fault..."

Now that things had come to this, Li Yi could only sigh. She felt powerless. She loved Zhang San too, but she didn't want him to ruin his future in Xuanqu for her sake. If Zhang San could live a better life, she would be content even if she could only watch from afar. This was her love for Zhang San.

But now that they've both become vampires, they're destined to live a life of constant wandering, but it's not all bad. At least they can depend on each other and are no longer alone.

“Who said that? Becoming a vampire might limit your options, but it’s not a dead end. Don’t you see that General Bai Qi, one of the two pillars of the empire, is a vampire? Why can’t I become like him? As long as I’m willing to give it my all, don’t worry, I will definitely give you a wonderful life! I will change everyone’s perception of vampires!” Zhang San hugged Li Yi and said confidently.

"I believe you. So who did you go to turn you into a vampire?" Li Yi nestled against his chest and asked her next question.

"This..." Zhang San hesitated for a moment. In order to transform into a powerful high-level vampire, he went to the wrong person to make a deal. This person was also Li Yi's nightmare, and he couldn't say anything about it yet.

"Who's outside?" In an attempt to change the subject, Zhang San pretended to notice someone outside and hurriedly walked to the door, but accidentally startled Cain.

"Nobody's here. It seems like it was just my imagination." Zhang San opened the door, looked around, and then went back inside.

How did he detect me? It seems Zhang San is no simple man after all. We've gathered enough intelligence this time. Let's go back now.

Cain emerged from behind an old, withered tree, glanced at the closed room, and turned to walk towards the Dragon Gate Inn.

On the eaves of Zhang San's house, a crow stared intently at Cain as he left, its blood-red eyes reflecting his gradually disappearing figure.
