(Some readers said that the recent update is not powerful, which is a fact, because there are some trivial things to socialize recently, not troublesome, but upset, plus a little lazy...... It should be better in two days, and the two shifts will be resumed as soon as possible...... Excuse me! ）

While Amos was shocked by the vampire's ability to infiltrate San Francisco, Shen Mu and Rom were disappointed, because Taylor's choice of the hostage exchange location in the city hall was a fundamental cut off Amos' idea of using force to save people, but it also made the two of them lose the exact location of the vampire clan's core stronghold in San Francisco.

Fortunately, not long after ten days had passed, Shen Mu and the others still had a chance.

However, the conundrum before them now is that if there is a hostage exchange at the city hall, then it is impossible to use force. If you want to ensure that Chrissy can be rescued without any problems, the only way is to take Professor Vincennes to the exchange.

"Ahem~ahem~, I'll go with me tomorrow." At this moment, Professor Vincent's voice came through the abandoned shelves of the factory.

Everyone turned their heads to look, and saw that Professor Vincent looked slightly tired, and the wrinkles and furrows at the corners of his eyes were extremely deep, which looked unbearable.

"Professor, don't worry, we won't trade you in exchange." Amos looked at Professor Vincent with a serious expression and reassured.

Apparently, Amos thought that Professor Vincent had heard the conversation and mistakenly thought that they would exchange him as a hostage, so he would explain.

"No, you misunderstood me, I mean it...... Didn't they want to trade me for me? Then I'll go. Professor Vincent shook his head, walked up to the crowd and said, "Don't worry, according to what you said, they just want to get my research results, and I will not be in danger." ”

Kelly looked solemn: "Professor, this is exactly what we are worried about, if your research results really fall into the hands of vampires, the consequences will be something we don't want to see." ”

"It doesn't matter, scientific research is not so easy to produce results, and my research has been stagnant for two years without progress, even if I continue to research, I dare not say that there will be a big breakthrough in the next two years!" Professor Vincent sighed and said with a little regret: "But saving people is different, if they can't see me tomorrow, maybe that little girl will be in danger, right?" ”

Amos and the others fell silent, on the one hand, they did not dare to risk Professor Vincent falling into the hands of the vampire clan, and on the other hand, they could not bear to watch Chrissy fall into the hands of the vampire clan and remain indifferent.

Shen Mu was on the side, and suddenly said, "Since Professor Vincent himself doesn't mind, then let's decide so, and exchange Professor Vincent for Chrissy tomorrow." As Professor Vinson said, the vampires must be trying to use him to continue their research, so there is no danger. It's not out of the question that we have a chance to rescue after the fact. ”

When Rohm heard this, he was slightly surprised, because Professor Vinson and his research results were very important to them, and it was directly related to whether the side quest could be completed or not. And because the vampire clan values Professor Vincent, it is also a huge bargaining chip. So he didn't expect that Shen Mu would agree to let Professor Vincent exchange Chriss.

According to Rohm's idea, even if he completely offended Amos, he would definitely have to completely control Professor Vincent. After all, it is a task reward for a D-tier side story, and two people are two D-tier side plots...... With this kind of reward, it is enough to make them give up everything.

But Rom also knew that Shen Mu must not have said this temporarily, and even if he did, he must have his own ideas.

Gao stood aside, holding a welding torch in his hand, and said, "But after all, there will be danger, vampires have penetrated too deep into the human world, once Professor Vincent falls into their hands, who knows where they will hide?" ”

"So, we'd better have some means, like putting a tracker on Professor Vincent's body or something." Shen Mu said.

Professor Vinson's eyes lit up, "Good idea, if you put a tracker on me, you can know where I am at all times." ”

Kelly shook her head: "No, vampires are very cunning, and it's not medieval anymore, even those vampires know how to use high technology." Ordinary trackers will definitely be searched. ”

"Then get some real high-tech, like those FBI and CIA, there must be that kind of tracker that is not easy to search out, right?" Röhm interjected.

"Yes, it's expensive, and it requires a deep relationship...... After all, intelligence agencies like that are two levels completely isolated from ordinary people, and you can't just have access to them if you have money or power. Amos said with a sigh.

"Can't you find the carrier pigeon?" Shen Mu frowned and said.

"Maybe, maybe not...... But it will definitely take time, but what we lack most now is time. Amos explained.

Indeed, the time given by the vampires is tomorrow at 9 o'clock in the evening, that is, they have less than 24 hours to prepare.

"Go to the carrier pigeon and ask them to find a tracker that implants the subcutaneous tissue, even if it's not the top-of-the-line, if it's good to use it. Even if the vampires were prepared, they certainly couldn't have everything in place at the city hall. They want to limit us with a special location in the city hall, but on the other hand, they themselves will be restricted! Even if they go back and scrutinize the equipment, at least there must be a place. Shen Mu looked at Amos and said.

When everyone heard this, their faces were shocked.

Indeed, the city hall is not an ordinary street corner, and even if the vampire clan uses their influence to infiltrate human society to secretly place the transaction location in the city hall, it will naturally be subject to the same restrictions in turn.

Amos they didn't dare to shoot at the city hall, but the vampires didn't dare even more, and they didn't even have time to do a detailed inspection.

The special location of the city hall is like a lock, locking the hands and feet of the Amos, and in turn locking the hands and feet of the vampires. I can't move, and you can't move...... Everybody didn't move, but in the end they bought Amos a certain amount of time.

"Okay, that's it! Gao, this time you go to the carrier pigeon and ask them to find a way to provide the tracker to us. Amos turned to look at Gao and said.

"No problem, I'll do it now." Gao nodded and said.

"I'd better go, the tracker still needs to have equipment to match, and in the end I must be positioning at home, so it's better for me to communicate with the carrier pigeon." Kelly said suddenly.

"This ...... Let's go high, it's not dawn yet, and the streets may not be safe. Let Gao bring a weapon and run away even if he encounters a vampire. Amos pondered for a moment, then spoke up.

Hearing Amos's words, Kelly didn't refute, after all, Amos was also for her safety.

Gao didn't say anything this time, silently took out two pistols and stuck them in his waist, then grabbed two magazines and walked out.

Gao was very fast, or rather very efficient, and after more than an hour, Gao came back with a tracker.

With Professor Vincent's cooperation, Gao embedded a small tracker under his skin with a specific device, and in order to prevent vampires from seeing something wrong at once, the selected location was still a place on the inner thigh that was not easily seen.

"Alright, let's all get some rest, and we're going to get Chrissy back tomorrow. And then we have a tough battle to fight. "Amos's injuries are not completely healed, and after being busy for a while, his face has become a little worse.
