Although he has known this for a long time, don't forget that it was Yagyu Qandai who told him, and Katharina came to the conclusion through her own experiments.

"What else?"

Ding Ning became competitive and wanted to show off, so he asked calmly.

"Also, it has a strong reproductive capacity. In addition to blood and skin contact infection, its transmission routes include airborne and waterborne infections."

Katharina's eyes were solemn, but Ding Ning was stunned. If he hadn't been sure that Yagyu Qandai had not left Paradise Island, he would have thought that she and Katharina had met.

"Airborne transmission is okay, it only lasts for five minutes. It can be avoided as long as we take precautions in advance, but waterborne transmission is troublesome. So far, I have not determined how long the virus can survive in water sources. Basically, these zombies in Darjeeling are

Infected by water sources.”

Speaking of this, Katharina showed a sad look in her eyes, then shook her head and said seriously: "There are ways to avoid airborne and blood infections, but airborne and contact infections are troublesome. As long as you are infected by these two

Infected in this way, although you will not turn into a zombie immediately, you will have

During the three-day incubation period of the virus, the virus will undergo a large number of divisions and reproduction. When the three days are up, the head of the virus carrier will explode with a bang, and the virus will spread, turning organisms within a certain range into

A person infected with a virus, this time the infected organism is no longer.”

Ding Ning had a look of astonishment on his face. He didn't expect that Katharina had already studied it so thoroughly. He had no chance to show off. He could only smile bitterly and said: "Water source infection is not a big problem. Although water source infection

has the widest range of infectivity, but the virus spreads in water

The survival time in the source is only twenty-four hours, and it will die after twenty-four hours. As for the virus-infected people, if they cannot find a way to kill the virus within three days, they can only be left to fend for themselves.

, the head explodes, and the virus spreads within a range of three hundred meters."

Speaking of this, Ding Ning showed a solemn look on his face: "I know you gathered so many infected people to facilitate virus research and produce virus serum as soon as possible, but it is really unsafe here. Once the infected people get sick,

, with such a dense crowd within 300 meters, everyone will be infected and will inevitably die."

Caesarina's beautiful eyes flashed with excitement, and she looked at Ding Ning with bright eyes: "Is this how you know?"

"Because I have also done experiments."

Ding Ning said vaguely, he didn't want to involve Yagyu Qandai anymore, so he could only give the credit to himself.

"Oh, you are awesome. You have solved my big problem now and saved a lot of time."

Katharina hugged Ding Ning excitedly, and then gave him a charming look: "For the sake of you helping me a lot, I will forgive you once, and we will make things clear."

"Forgive me once? Forgive me for what? It seems like this is my first time meeting you, right?"

Ding Ning looked confused. He didn't know what style of smoking this woman had.

"Hmph! My dad said that he wanted to introduce me to you, but you refused without even seeing me. Do you think you owe me something?"

Caesarina's big watery eyes stared at Ding Ning fiercely, her eyes full of unspeakable grievances.

Ding Ning scratched the back of his head in confusion: "Who is your father?"

"Hmph, stop pretending to me, don't you know who my dad is?"

Caesarina snorted angrily!

"I...I really don't know, who is your father?"

Ding Ning searched his brain and couldn't remember who was going to introduce him to his girlfriend, and looked confused.

"You really don't know?"

Seeing that he didn't seem to be faking it, Caesarina asked suspiciously.

"My conscience, I really don't know. If I knew, how could I refuse such a beautiful beauty?"

Ding Ning looked at her beautiful blue eyes, and his mouth was filled with joy as a habit.

"Am I really beautiful?"

Caesarina asked somewhat unconfidently. Thinking of the rolls of eyes and pointing fingers that she had suffered since childhood, a trace of sadness flashed in her eyes.

"Of course, I'm almost fascinated by you before I even see your face. Do you think you're pretty?"

Ding Ning's face has been tempered among his women for a long time, and his face is thicker than the corners of the city wall. He can say nice things just by opening his mouth.

"Hmph! You're so smooth-talking, and you said I'm beautiful before you've even seen me. You must be talking nonsense!"

Katharina felt happy in her heart, but she said contemptuous words with duplicity.

"If a man is willing to talk to you with sweet words, it means that he cares about you. If he is not interested in you, why would he talk to you with sweet words?"

Ding Ning lit a cigarette and said in a serious tone.

"Come on, go ahead and coax those little girls who are just starting to fall in love. If a man talks sweetly to a woman, it can only mean that he has evil intentions and bad intentions."

Katharina said disdainfully, but her eyes flashed with shyness. Considering the environment where she grew up, no one had ever said such ambiguous words to her.

Some are afraid, some are disdainful, and some just want to go to bed with her nakedly. If she didn't have a father who even gave the Pope a headache, she would have become someone else's plaything. Love, this thing is not good for her.

To say it is simply a luxury.

"Then you also need to have the capital to make others have bad intentions. Isn't this enough to show your charm?"

Ding Ning now opened his mouth to say nice things, and added flattery in a roundabout way.

"Huh! I don't believe it. Anyway, you have already rejected me. Even if you have thoughts about me now, no matter how nice you say, I will never agree to you."

Katharina proudly raised her delicate chin at an angle of 45 degrees, making Ding Ning dumbfounded. Sister, I am just making you happy. You are thinking too much.

"Up to now, I still don't know who your father is?"

There was nothing to talk about today, so Ding Ning could only change the topic and become more curious about this.

"My dad is my dad, and I don't even know his name."

Katharina's answer surprised Ding Ning: "You don't know your father's name?"

"Yes, I have only seen him a few times since I was a child."

Katharina lowered her head sadly, which made Ding Ning feel pity for him inexplicably. This child was also a poor child who grew up in a single-parent family.

"However, they all called my father a scourge and called me a bastard who is a scourge."

Katharina didn't know why she mentioned this to Ding Ning. Maybe it was a woman's potential revenge after learning that she had been rejected. She just wanted to watch Ding Ning blame herself and feel guilty!

Big disaster?

As if a thunderbolt flashed through Ding Ning's mind, he suddenly remembered Tian Xuanzi's unreliable old guy, and said with a tongue-tied mouth: "You... are you a saint of the Holy See?"

"Saint?"

Katharina's long eyelashes flickered, her eyes were a little dim, and there was a hint of self-deprecation in her tone: "That's right, they have called me this on the surface since I was a child, but they all call me this behind my back.

A hybrid, too, a mixed race, a hybrid!"

Ding Ning was completely speechless. How could he have imagined that Katharina would be the mixed-race daughter that Tian Xuanzi wanted to introduce to him? Perhaps in the eyes of many people, mixed-race children are beautiful and tasteful, and they wish they were mixed-race.

But it also depends on the situation. For some people who think that their blood is noble and pure, being mixed-race is a shame, especially in a religion like the Holy See, where even the Lord they worship is a blond and blue-eyed Westerner.

The saint is a mixed race, it's strange that they can't point fingers behind her back.

What's more, she is the daughter of the previous saint and the great scourge Tian Xuanzi. Who in the West doesn't get a headache when mentioning Tian Xuanzi? She gave birth to a bastard from the saint of the Holy See. This is a great shame for the entire Holy See.

, If they didn't dare to provoke Tian Xuanzi and the Pope didn't pursue the case, I'm afraid Katharina and her son would have been burned at the stake by these fanatical believers. It's no wonder she can live a good life in the Holy See.

But when it comes to this, he is still surprised that the old pope can be so tolerant. After all, the old guy is a strong man at the peak of the Holy Martial Realm. Is he so afraid of Tian Xuanzi?

"You can't say that. I just like mixed-race children. Mixed-race children are so beautiful. They have the fragility of Eastern women and the exotic charm of Western women. All men like them!"

Ding Ning looked at Katharina's dim eyes and tried his best to comfort her.

"Then why did you reject my dad when you heard that I was mixed race?"

Katharina looked directly at him with her pure and flawless eyes, and there was actually a hint of resentment.

Ding Ning's heart skipped a beat. Isn't my charm that great? As for making you fall in love at first sight? But the explanation still needs to be explained: "I didn't reject you because you are a mixed race, but because we have never even met."

, if I agree, wouldn’t this be irresponsible to you?”

"Oh, that's good. I thought you were discriminating against mixed-race people."

Katharina turned her anger into joy and said happily.

"How is it possible? I don't discriminate against anyone."

Ding Ning had a sneer on his face, how did this girl become the president of the World Medical Association? She was so simple!

Fearing that she would say something that would be difficult for him to resist, he quickly changed the subject and said: "By the way, if you don't properly serve as your saint in the Holy See, how can you become the president of the World Medical Association?"

"I grew up in the Holy See. Except for my mother, no one played with me or talked to me. Others respected me on the surface, but behind my back they all called me a bastard. Once, a Holy Son took advantage of me while I was sleeping and raped me.

The female believer who was serving me was defiled, so I couldn’t bear it anymore so I beat him up, and accidentally beat him to death!”

That incident seemed to have greatly stimulated Katharina. When she talked about it, there was still anger in her eyes: "This incident alarmed the Holy Knights. They arrested me and wanted to put me on trial. Finally,

It was the Pope who came forward to save me. Probably because he was afraid that I would cause trouble again, he sent me to a Shinto temple to study. I became obsessed with medical skills.

, the Pope saw that I was very talented in studying medicine, so he specially invited some famous doctors to teach me. Later, I made some achievements in the medical field and was recruited by the World Medical Association. Then the old president accepted me as his disciple and taught me his medical skills.

I taught him everything he could, and some time ago my master was in poor health and resigned from the position of president, so I became the president of the association in a daze."

Ding Ning was dumbfounded when he heard this. He knew that there was a saint in the Holy See, so how could there be a saint? Also, this Caesarina looked so weak that she actually killed the saint. This saint must be too weak.

Seeing Ding Ning's expression of disbelief, Katharina said coquettishly: "What's that expression of yours?"

"Why is there still a Holy Son? What is the Holy Son?"

Ding Ning asked curiously.

"Gee, the Holy Son is not a thing."

Katharina was amused by him and laughed sweetly, and then explained: "Every year, the Holy See selects some well-qualified young girls from among the believers for training. The Holy Son, like the Saint, is the future successor of the top leaders of the Holy See.
