Ye Qing carries a computer with him that can connect to the Public Security Bureau's database.

Based on the vampire's appearance, clothing and other characteristics, they found out her identity when she was alive.

Her name is Wan Fang. She rents a house in this community. She has a history of fraud and drug abuse. Just yesterday, her boyfriend was found running out of the community with a knife, and then jumped into the moat next to the community and committed suicide. The police found marks of chopping on the boyfriend's body with the knife, and went to Wan Fang's rented house to look for the body, but they only saw blood, but no body. Wan Fang disappeared mysteriously, but she reappeared in the underground parking lot in this strange form at night.

"It is very likely that Wan Fang had an argument with her boyfriend and was hacked to death by him - she was stabbed in the heart and her throat was slit. Then she was possessed by the dormant body of a vampire and became a vampire. She hid in the community, waiting for an opportunity to suck blood." Li Yuebai said.

The little girl was just an ordinary resident in the community. In the middle of the night, her parents quarreled and fought for some unknown reason. The little girl was scared, so she secretly opened the door and ran out, but she met Wan Fang who had turned into a vampire.

After a fierce fight just now, Li Yuebai's body was splattered with a lot of disgusting juice and blood, and he was bound to be unable to show his face to anyone, so he sent Ye Qing to send the little girl home. Li Yuebai was responsible for parking the car, and after Ye Qing came back, the two went upstairs together to the house rented by Gu Xisha.

Li Yuebai was so tired that he couldn't think anymore, and he was too lazy to entertain Ye Qing. He went to the bathroom to take a shower, found a pair of loose clothes to change into, and lay down on the sofa. Only then could he calm down and continue thinking about the problem.

Ye Qing sat on another sofa holding a computer, his face glowing blue under the light from the computer.

"Wan Fang just said that she was the Countess of Karnstein. What does that mean?" Li Yuebai rubbed his head, took out his mobile phone from his old clothes, and opened the search engine.

——Countess Karnstein is a legendary vampire who lived in Austria in the 16th century. She only sucked the blood of young girls. The basement of her castle was filled with the corpses of young girls.

This could explain why Wan Fang targeted a little girl.

"But we still know too little about vampires." Li Yuebai sighed: "Now we only know that pure silver can kill them."

That is to say, in order to defend against vampire attacks, a large amount of pure silver must be prepared - pure silver weapons, pure silver bullets... The price of pure silver is not expensive, only a few dollars per gram, but if you want to use it in large quantities, the amount of money you have to spend is still considerable.

I checked Gu Xisha's account balance on my mobile phone and it was obviously not enough.

The last time he wore it, the Crown Prince was magical and obedient like a plug-in, and would do whatever he was asked to do without asking. But this time, Ye Qing was not so easy to fool.

Li Yuebai held his forehead and started to prepare a speech in his head as if he was preparing for a lesson.

Worldview, methodology, what, why, how to do it...

First, he had to tell Ye Qing the concept of vampires and the origin of vampires, then he had to explain to each other how much trouble they would cause in the future, and then he had to discuss how to avoid it. Most importantly, he had to explain why he knew so much... Teacher Bai felt that his head was filled with messy characters, and he was so tired that he didn't even want to say a word.

Fortunately, Ye Qing helped him make the choice quickly and decisively.

"Xisha." Ye Qing raised his head from the computer screen: "Why do you know so much?"

As expected, it was exposed so quickly.

Ye Qing's eyes were cold, full of scrutiny and 100% rationality, eyes that could see through everything.

"Xiao Ye, listen to the master explain it to you in detail, this is what happened..." Li Yuebai sighed, put his feet on the tea table, and prepared to read out the millions of words in his mind like chanting a sutra, but when he was about to speak, he changed his mind.

It's too troublesome.

Li Yuebai is not afraid of anything except trouble and endless cover-ups.

"I am a time traveler." Li Yuebai said word by word.

"..."Ye Qing narrowed his eyes.

"Gu Xisha will be fine. Once I solve the problem and leave, he will be back." Li Yuebai said the key point first: "You and I are allies."

"How do you prove it?"

"If I wanted to hurt you, I would hide behind Gu Xisha's identity and keep hiding." Li Yuebai shrugged: "You trust him anyway."

"You are willing to expose your identity. What do you want to tell me?"

"The situation is critical. I don't have time to beat around the bush with you." Li Yuebai explained the general situation and emphasized three points in particular:

First, vampires will start to appear everywhere soon.

Second, Ye Qing will be possessed and become a vampire.

Third, Gu Xisha will be captured by vampires and transformed into a killing machine to kill Ye Qing.

…

After Li Yuebai finished speaking, Ye Qing fell into a brief silence.

"If you believe me, things will be much easier." Li Yuebai said sincerely: "If you don't believe me, I will provide more

Evidence.

He closed his eyes and waited for whatever might happen.

The system doesn't say what will happen if your identity is exposed. Anything can happen.

However, what Ye Qing said was beyond his expectations.

"I believe you." Ye Qing nodded: "I am also a time traveler."

WTF!

So you are too!

As expected, the world has been turned into a sieve, and time travelers are everywhere!

"What a coincidence." Li Yuebai smiled bitterly: "How can such a coincidence happen?"

"Ding! Congratulations on meeting each other! Please choose whether to form an alliance for this mission." The system popped up happily.

Li Yuebai chose yes without hesitation.

"Both parties choose [Yes], and the alliance is established. If any one of the allies dies, the mission will fail."

The system is happier.

So this alliance is such a bastard? Li Yuebai just wants to beat up the system.

But on second thought, for two strangers, this setting is perfect, and it perfectly avoids the possibility of mutual betrayal and murder.

Li Yuebai's tense nerves suddenly relaxed, and he wanted to lie down on the sofa.

it’s done!

"When did you get through here?"

"Barbecue restaurant, a little earlier than you." Ye Qing replied.

Ye Qing, like Li Yuebai, came from a world that was similar to the present world, except that there were no vampires. Li Yuebai couldn't tell whether they were from the same world, after all, there were too many worlds and they were too similar to each other.

As for Ye Qing's personality and family situation, they are similar to Ye Qing in this world, so he only needs to play his true self to look very similar.

Ye Qing also has a system, which is the same as Li Yuebai's system and provides the same information.

"Have I seen you in the last world?" Li Yuebai thought of a nonsensical question: "Are you in "Flowers Falling in the Capital"?"

"What is Shangjing Luohua?" Ye Qing frowned and denied: "I have no idea."

"In ancient times, during the Daduan Dynasty, the emperor was Murong Feng."

"no."

"Is this your nth time traveling through time?" Li Yuebai continued to ask.

"I don't remember. It might be the first time because I don't remember there was another world ahead." Ye Qing frowned.

"Oh, newbie?" Li Yuebai smiled and said, "It's okay, the teacher will protect you."

"Um."

Although he said he wanted to protect others, Li Yuebai actually only had two vague plans for the next step:

1. Get a custom-made weapon.

2. Collect information about the appearance of vampires everywhere.

The second one was relatively easy to handle. Ye Qing was a computer expert in the Municipal Bureau. He only needed to take over the job of connecting the lines.

Pay extra attention to any police calls suspected to be related to vampires, report to your superiors, and proactively request to investigate.

The first one is difficult... Our country has always had strict management of weapons, and even the police are subject to strict restrictions on carrying guns. As an ordinary law-abiding citizen, Li Yuebai has no idea where to get weapons.

Ye Qing...wait, someone like Ye Qing who can hide a knife under the car seat must have a way, right?

"Wait a minute, I'll search the database." Ye Qing answered seriously, then closed his eyes and tapped his forehead lightly with his right index finger.

There's an inexplicable sense of robot cuteness.

"Yes." Not long after, Ye Qing opened his eyes and said, "I have a friend who I have known for many years. He was engaged in illegal ammunition sales online a few years ago. Later, the news became tense and he dared not sell anymore. He has not been able to sell the bullets in stock..."

"Where's the gun?"

"I have the guns given to me by the bureau." Ye Qing smiled: "One is a Type 92 and the other is a revolver."

Both of these guns use the most standard 9mm caliber bullets.

"Why are you allowed to carry two guns when you are not on duty? How old are you?" Li Yuebai thought it was totally unfair.

"I have passed the country's calmness test." Ye Qing said, "There is absolutely no possibility of causing any bad incidents. I am armed with a gun, and the only danger is - suicide."

In other words, even if everyone in the city bureau is unreliable, Ye Qing will be the most reliable one.

"Pure silver is easy to make. As long as we have large-scale electroplating equipment, we can electroplate a layer of silver on the bullets. Or we can put silver powder and silver particles into the ammunition, like we just did." The more Li Yuebai thought about it, the more he felt that things would go smoothly: "This kind of electroplating process can be done by many lighting factories and electrical equipment factories."

He casually searched the keyword "electroplated silver" on the search engine, and soon several advertisements popped up, the most prominent of which was from the famous Bailiang Lighting Company.

"You see, for a company like Bailiang, of course we don't have to look for such a high-level one. We can just look for any small factory that is about to go bankrupt and think of a way to acquire their workshop...but it's a bit troublesome." Li Yuebai had never done this kind of business and was racking his brains to think of how to requisition other people's workshops and machines.

"Bailiang Company is OK." Ye Qing nodded: "It's under my family."
