I work as an editor at Marvel.

Because this test involved the safety of their own potential legend, the entire blood research lab immediately adjusted the priority of the mission and began to study and analyze Bella's blood.

With the researchers working together and putting in extra hours, preliminary results were quickly obtained.

"Master Merlin, would you like to take a look at this report?" The director of the Blood Research Institute walked up to Merlin with a huge paper report in his hand.

"No need, just give me a brief explanation." Merlin showed no intention of opening the report. Even a legendary figure's knowledge has its limits. In such a specialized field, Merlin, like ordinary people, couldn't quite understand it.

“Okay.” The director seemed to have guessed Merlin’s plan. After he finished speaking, he took out a piece of paper filled with information that he had refined, using common language.

After handing the paper to Merlin, the director slowly began to speak, “We analyzed the composition of the blood, and the vast majority of researchers believe that the blood has been purified. This purification method is unprecedented and does not belong to any known method.”

"However, after testing each of the isolated elements, we found something familiar: the vampire meme virus. Compared to the version we have, the blood version has undergone structural reorganization, and its efficacy, incubation period, and other indicators have changed."

"Most importantly, in routine tests, we found that its resistance to alien energy has been greatly enhanced, and it has formed a symbiotic and mutually beneficial relationship with the host body. It has the ability to spontaneously purify the magical bloodline in the host's body. However, because there are too few testable target samples, we are unable to measure the relevant purification data for the time being."

Merlin nodded slowly. There was a saying in the Clock Tower: if there is something that no one knows who did, it is most likely that it was Thanos.

The meme virus was created by Mephisto and Dracula from Hell, and the fact that these two were able to meet was entirely due to Thanos's intervention.

"What are the side effects of this purification?" Merlin then asked.

"Regarding the side effects, we certainly haven't fully explored them, but based on the information we have, we can deduce some obvious things. For example, during the purification process, due to the mutation of the bloodline, the host will gradually separate from the original race, and due to the rejection caused by the change in race, they will hate their original race's companions even more. The closer the bloodline connection, the stronger this rejection will be."

Merlin nodded. The director and the others' calculations should be fairly accurate. In Dumbledore's future account, after Bellatrix changed, besides the increase in magic power, the biggest change in her was that she became more cruel to humans, whether wizards or non-wizards.

The methods were so cruel, it was as if they were treating a group of animals that had a grudge against them, rather than their own kind.

"Master Merlin, there is one more thing," the director said as Merlin fell into thought.

"What is it?" Merlin asked, looking up. He was wondering how the memetic virus had spread from Hogwarts. Could it really be Dumbledore's problem? But that was unlikely. The original version of the memetic virus shouldn't have been able to attach itself to Dumbledore.

"Because memetic viruses are among the most serious infectious viruses, we immediately reported it to our superiors after it was discovered," the director said. This was a rapid response channel left over from the last virus outbreak.

"Hmm, that's good. Is there a problem?" Merlin didn't quite understand. He was going to report it anyway, and he might also need to get some rapid testing kits to test the students and professors when he went to the other Hogwarts.

"The Plague Department of the Heavenly Court contacted us directly after the information was uploaded. Their leader seems to be very concerned about this matter. Coincidentally, he's here." The director gestured slightly behind Merlin.

Merlin turned around and saw Lu Yue, the minister of the Plague Department, standing not far behind him with a smile.

"Hello, hello, you must be Master Merlin, right? I am Lü Yue from the Heavenly Court. I have long admired you." Lü Yue extended his hand and said to Merlin very politely. This attitude made Merlin feel that this person might have something to ask of him.

"Hello, I've long admired you too, and indeed, seeing is believing. This meeting proves that the title of the Plague Emperor is truly well-deserved." Merlin replied with a forced smile. They were both legends, and since the other party was being so respectful, he couldn't very well keep a straight face.

"It's just an empty reputation, how can it compare to Mr. Merlin? You've truly taught a legend..." Lü Yue started the mutual praise mode.

"You're too kind. Well, Mr. Lü Yue, what exactly do you want to see me about?" Merlin quickly got down to business. If he kept praising him like this, he might not be able to get to the other side today.

"A straightforward and outspoken person, a man of strong character." Lü Yue casually flattered Merlin. "It's like this: the last incident with the meme virus has made all members of the Plague Department remember it well. For so long, we have never given up on researching similar viruses, just waiting for an opportunity to regain our honor."

Upon hearing this, Merlin immediately realized that the Heavenly Court wanted to get involved, but was afraid that Merlin would not agree. After all, the meme virus did not break out in their own territory or among their allies. According to the jurisdiction of discovery, the first person in charge of this matter was the legendary Merlin, and the first management party was the Ouroboros, to which Merlin belonged.

“Everyone makes mistakes sometimes, so don’t worry about it too much,” Merlin said politely, pausing slightly. “Actually, I was just thinking of initiating a joint application. As you know, this type of virus can spread to a planet at a time, so we may need to prioritize testing the worlds with connecting channels.”

"Of course, random sample testing of the Resident Evil world, Conan world, and other worlds has already begun. As for the other planet you mentioned in your report, we have prepared more than five million test kits, which are ready to be used at any time. If needed, we can also provide another ten million test kits within twenty-four hours."

A glint flashed in Lü Yue's eyes. He had been waiting for this opportunity for a long time. This time, he was determined to regain all the face he had lost and give Dracula and his men a big surprise, letting them know that losing face to his tribe was not an easy thing to resolve!

Chapter 341 The Golden Crow Plan is Remarkably Effective

"Ivy, do you know what kind of test we're going to be doing this time? The professors all seem really serious," Harry whispered to Ivy in the Great Hall of Hogwarts.

Ron and the others standing nearby were also very nervous. They watched as Professor McGonagall and the others' expressions grew increasingly grim, making them feel as if a serious mass cheating incident had occurred at Hogwarts.

"I don't know, but don't worry, nothing will happen," Ivy said reassuringly. "The hardest thing to solve is something that can't be detected. If it can be detected, then we can definitely find a solution."

Despite Ivy's words, Harry was still a little worried. Just as he was about to ask more questions, the previous batch of testers had already finished their tests.

Professor McGonagall held the list and read out the names of the next group, "Ron, Harry..."

The wizards whose names were called entered the testing room one by one. After their blood samples were collected with a small needle, they were led back to the lounge by their respective prefects.

Several hours later, the last wizard's test was completed.

"How is it going?" Professor McGonagall was very concerned about the matter and immediately went to Merlin to ask.

"It's terrible. The lowest infection rate among the four houses is 60%, and the highest is Slytherin, at a full 87%," Merlin said, looking at the preliminary test results.

"Moreover, the situation among the professors is also not good. Only one person has been found to be completely unaffected so far: Professor Lupin. The werewolf virus in his body seems to have a completely competitive effect on this meme virus."

Professor McGonagall took a deep breath. It was hard to believe that, without anyone noticing, the entire Hogwarts had been overrun by this unknown virus.

At that moment, Ann suddenly appeared in front of Professor McGonagall, with a report in her mouth, and placed it on the table.

After briefly glancing at the report, Merlin was even more troubled. "The situation at the Ministry of Magic is even worse. The sampling test results show that 100% of the samples were positive, without exception."

“What should we do now?” Professor McGonagall asked.

"With such a high rate, isolation is no longer very effective, but I still recommend temporarily separating the infected and uninfected. I will contact the Plague Department immediately to see if we can come up with an emergency plan," Merlin said, putting down the report.

Without saying a word, McGonagall went straight out, intending to lead the other professors to isolate the students. Fortunately, one of the professors was completely uninfected; otherwise, the uninfected students wouldn't even have a teacher.

Merlin waited another half hour before the remaining two reports were sent over.

One sample was taken from ordinary people in this world, those Muggles mentioned in the magical side. The result was zero; out of 15,000 blood samples taken, not a single person was infected.

Merlin didn't believe that none of these people knew anything about vampires, so the only possibility was that the meme virus here had a target: all those who possessed magic power.

Another report was a random check within the Federation of People's Unions and the test reports of all the students who came here. The test results were also zero. However, unlike the other three reports, this report included an indicator: the average survival time of the virus in the blood of these people.

This time is far below the normal average level; even with the maximum dose of the virus, the infected person can recover on their own in a short period of time.

Clearly, the Human Union's plan has yielded significant results, as these Human Union citizens affected by the Three-Legged Golden Crow have developed immunity to the currently discovered memetic viruses.

Therefore, the simplest and most effective way to solve the Hogwarts virus problem right now is to send all these people to Earth.

But that's impossible. Putting aside whether Earth would allow so many people to enter all at once, even if they did, Merlin couldn't possibly bring all the infected over. The passageway isn't big enough; he himself was just a blur.

"The three-legged golden crow, the goddess of dawn..." Merlin murmured, as if he had thought of something.

Meanwhile, after obtaining enough blood samples, the Plague Department began to analyze this variant of the meme virus.

After losing face in front of the Heavenly Emperor last time, Lü Yue led his men to incorporate the meme virus into the Plague Department's management virus network, and this time the effect was immediately apparent.

Under the influence of the venereal disease department, the activity of memetic viruses in the blood of infected individuals drops by more than 90%. The remaining viral activity would be difficult to break through the immune defenses of an ordinary person, let alone the fact that medication can now be used in the venereal disease department.

After confirming that the spread of the virus could be contained at any time, the Plague Department shifted its focus, for example, by using memeviruses to locate Dracula's position, and also to see if anti-memeviruses or other specialized parasitic viruses could be used for a remote counterattack.

"Minister, Master Merlin is looking for you," a member of the Plague Department said as he quickly approached Lü Yue.

Lu Yue was now in high spirits, his eyes shining with a captivating light. With each step forward in the reverse work, Lu Yue's mood improved.

"Master Merlin, is there anything I can help you with?" Lü Yue took the communicator and asked directly, as he owed this person a huge favor.

"What? Use the power of the Goddess of Dawn instead of the Three-Legged Golden Crow's divine power for disinfection? Please wait a moment."

Lu Yue looked at the others, signaling them to speak. Merlin's idea seemed logically sound.

"Well, Minister, there's no problem, but the anchor point of the Goddess of Dawn is in our star. If there's no similar concept on the other side, the effect might not be good, and the duration might not be very long."

Lü Yue nodded and relayed the technicians' opinions to Mei Lin verbatim.

“Actually, Master Merlin, there’s no need to rush. The specific drug for this virus is almost ready. Give us three more months, and we should be able to develop a universal drug,” Lü Yue added.

Don't think three months is a long time. In drug development, three months is the shortest possible time. Any shorter and clinical trials might not even be conducted. In non-emergency situations, such a drug would not save lives, but kill them.

Merlin mentally estimated that the three months Lu Yue mentioned referred to the normal flow of time. If the Time Chamber could be used, the time could be shortened, but based on his experience, Merlin judged that it would not be less than two months.

"Okay, I understand. Please speed things up." Merlin said and hung up the phone. Before the medicine was ready, perhaps they should try other methods.

Chapter 342 Voldemort? Just a small stepping stone.

"What do you mean?" Merlin floated beside Leona and asked softly, having just recounted the results of his brief conversation with Lü Yue.

"Hmm... has it all been settled with my brother?" Leona was in a very conflicted state. She wanted to agree but couldn't because of her limited abilities. If she didn't agree, she didn't want to lose to her brother.

Merlin nodded, clearly indicating that the Three-Legged Golden Crows had done a very good job. Leona was not on Earth during this time and was unaware of the situation, but Merlin himself was in the solar system and could feel the changes little by little every day, which had accumulated into a change that could not be ignored.

"Phew~" Leona let out a long breath. Some things really can't be done recklessly, because she can't afford the consequences. After all, this matter could affect intelligent life in an entire world. "I really want to agree, but really, I'm powerless to do so."

Merlin laughed when he heard Leona's reasoning. "I understand. Without an anchor point, without relevant concepts, and even if the collective consciousness here is not necessarily on our side, the success rate cannot be guaranteed."

Leona nodded vigorously; that was exactly what she thought.

"However, it's not without a solution," Merlin said, changing the subject.

Leona paused, tilted her head to look at Merlin, and waited for him to tell her the solution she had come up with.

The situation is clear: without the sun, Leona's own power cannot support her in erasing the memetic virus of this world directly from the timeline. However, the difficulties she faces are actually much smaller than those of the Three-Legged Golden Crow, because the memetic virus of this world does not infect ordinary people.

In terms of population size, the two sides are not even on the same order of magnitude.

Moreover, anchor points and concepts are not things that cannot be constructed later.

"Remember that noseless terrorist we've been looking for?" Merlin asked.

Leona nodded. Voldemort, huh? Freddy is still lurking inside Peter's body, waiting for Peter to bring him to Voldemort's side.

“I had a conversation with Professor McGonagall. This Voldemort is not only infamous in the magic world of this country, but also attracts a lot of attention in the magic world of other countries. After all, the conflict between purebloods and non-purebloods exists in the magic world of every country on this planet.”

"Therefore, among our target audience, which is all wizards, Voldemort is extremely well-known, making him the best anchor point!"

After a moment of realization, Leona was filled with doubt again. "You mean you want me to become Voldemort?"

Merlin was speechless. What a terrible idea! How could such a young boy be so slow on the uptake? To replace Voldemort as the Dark Lord? What a horrible thought!

"Of course not. What I mean is, you can take down Voldemort in front of everyone, establish your reputation as the Goddess of Dawn, and use Voldemort as a stepping stone to gain your first anchor point in this world," Merlin explained.

"Oh, I get it, you want me to replace Harry Potter," Leona said, a lightbulb going off in her head.

...

This child's thinking is always a bit strange, but it seems like there's nothing wrong with it.

In Merlin's plan, Leona was to become Harry Potter's savior. First, she needed to make a name for herself, then she needed to make sure everyone saw her moment of victory, and finally, she needed to reverse all the wizards' perceptions of Voldemort through decisive blows and powerful strength.

"That's pretty much the gist of it. What do you think?" Merlin asked, his hands behind his back.

"We can give it a try." Leona suddenly felt confident, and at the same time, she was a little excited. If the plan succeeded, at least she wouldn't be left too far behind by her brother.

Moreover, the chances of this plan succeeding are not low. The prerequisite of gaining fame is not difficult to achieve with the cooperation of Hogwarts and the Ministry of Magic.

Many people may think Leona is just trying to attract attention, but any name is fine. Merlin just wants enough wizards to know about Leona. Even the initial contempt and disdain will become an asset when everything turns around.

The second key point is to let everyone see the victory brought by Leona, which is a little difficult.
