Good news from Hawaii and bad news from London, where Downing's cancer research team has basically diagnosed Prince Albert with stomach cancer, but it is not known how deeply the cancer cells have infiltrated. As mentioned earlier, each layer of cancer cell invasion requires a 1 in 100 million probability of mutation, and once this mutation occurs, the patient's condition will become worse and worse.

Cancer is the king of diseases, and god-level scientists who lack biological data are not sure to treat this disease. Downing told the queen the sad news, and he was afraid to see the children, so he told the queen the truth alone. In the end, the heartbroken queen told her husband again, she was not as strong as her husband, and it was better to hold this matter in her heart than to find someone closest to her to share it, even if this dearest person was the patient who died all her life.

The prince was very curious about the pathogenic mechanism of cancer, and calmly discussed the disease with Tang Ning. After some careful discussion, the prince finally believed in the existence of the king of diseases, and by this time all his religious beliefs had been wiped out, and with it an infinite worship of science, but it was a pity that the rector of Cambridge University might not have many good days to enjoy without faith.

When the prince left, the headmaster's only hobby became to visit Windsor Hospital from time to time to admire the normal and cancerous cells taken from his stomach, and to observe a pair of brothers who were too anxious to fry each other.

Albert himself is a talented prince, so he also likes his talented daughter the most, Princess Louise. Princess Louise has shown great artistic talent, mainly painting, and after she returned from Shanghai, she often displayed Lang Shining's "Hundred Horses" that Downing bought for her, and often wondered when she would be able to paint so beautifully.

On this day, when she was showing off her thoughts again, Albert looked at her innocent appearance, and finally couldn't hold back her tears, this was the first time that she was so sad that she couldn't help herself after learning that she had a stomach. Oh my God, I'm going to never see my daughter again!

And then, and then...... Of course, Louise knew about her father's illness, and it was not as simple as he and his mother claimed.

The heartbroken little girl burst into tears, and finally wiped her tears as she ran to the Situo Garden to find the culprit who had revealed such bad news and asked for clarification.

When Louise appeared in front of Downing, he was pondering a very serious philosophical question: should we accelerate the development of biotechnology? The Prince's illness reminded him of saying goodbye to his loved ones, of course, 10 years ago, the world before he came to this world, the world that had already solved the problem of cancer, but he still had to say goodbye to all his relatives and friends. Because he "made a mistake," a crime that he did not consider to be wrong.

At that time, he belonged to a secret society. This is the world's top hacker group, and their dream is to give humanity the freedom to create any powerful machine. Because the war between humans and artificial intelligence has made human beings frightened by artificial intelligence, they have abandoned martial arts and artificially restricted the development of science and technology in many fields, including robots. And the ideal of him and the organization is to abolish this restriction, because they believe that there is more than one intelligent creature in this universe, and the slowdown of development may lead to the defeat of the human race on Earth in the interstellar technological competition, and thus lead to the demise of the civilization on Earth. This, coupled with his urgent need for funds, made him a "drug offender", a ridiculous crime. In fact, he is an idealist, not a person who does things that are harmful to nature and reason for his own selfishness.

The little princess cried like Guan Gong, Tang Ning almost didn't recognize it, of course, after recognizing it, she knew that she must have known some bad news.

"I ...... I see......" The little princess was a little incoherent.

Tang Ning looked at the heartache and sighed: "Don't cry...... he doesn't seem to have any expertise in comforting people, and he doesn't know what to say.

Louise: "There's no chance at all?" ”

Downing: "I'll do my best, but I'm not sure." "A medical person, if he does not have relevant medical information in his hands, it is not a problem, and this kind of medical data requires years of accumulation, and advanced equipment is also needed, and it is obviously impossible to create technology at this time.

Louise got a glimmer of hope, clenched her little fists, as if to pinch a rope to save her life, and said, "You must have a way, people say that there is nothing in this world that you can't do." ”

Downing found a wet towel to wipe Louise's tears, and said calmly: "There are only such people in Hans Christian Andersen's fairy tales, I am just a mortal, and I was almost burned to death in the theater of the Royal Mint in Belgium a few years ago." The world will not be ruined because of great love, nor will it not run because it is full of absurdity, it will always exist without the slightest emotion in all human strife. Billions of years ago to the present, from now to billions of years later, it is always staging a farce of life and death, and the only constant eternity is that life itself will not disappear lightly. And the individual living beings, our specific people, are forgotten by nature like objects that are discarded at will after a sacrifice. ”

Louise was even more heartbroken, and at this time, Tang Ning said: "There is probably a little chance, I just thought of a treatment plan, but I don't know if it works." ”

Louise: "What's the plan?" Can I listen to it? ”

Downing: "Do you really want to hear it?" ”

Louise: "Of course, isn't it convenient?" ”

Downing: "Uh...... Nothing inconvenient. Then I said: my plan is to kill cancer cells, cancer cells are very similar to normal cells, but it is not without a different method, otherwise we would not be able to diagnose it at all. Cancer tissue has a very prominent characteristic: high permeability and retention.

How did this come about? It turns out that the microvascular endothelial space in normal tissues is dense and structurally intact, and macromolecules and lipid particles are not easy to penetrate the blood vessel wall, while solid tumor tissues have abundant blood vessels, wide vascular wall gaps, poor structural integrity, and lack of lymphatic reflux, resulting in selective hyperpermeability and retention of macromolecular substances and lipid particles. ”

He spoke for a long time, and the literary and artistic girl only understood a few words: "Cancer cells have very prominent characteristics." ”

"And then...... And then what? The literary beautiful girl asked unconfidently.

Tang Ning thought that her train of thought had followed, and continued to wonder: "Then we use a nano-sized particle as a macromolecular substance, so that it can be enriched in cancer cells. This kind of nanoparticle is gold nanoparticle, gold is a large atomic weight element, it has a prominent characteristic - there are many electrons, under the light wave irradiation, the electrons of nano gold vibrate violently, and then the temperature rises violently, killing cancer cells, and it is possible to cure your father's disease. ”

The beautiful girl of literature and art blushed even more when she heard it, like Guan Gong who had drunk wine, she thought that her knowledge was not erudite enough to understand, how could she know that what Tang Ning said involved subatomic structure, not only did she not understand the little princess who followed the royal teacher to learn cooking, gardening, housework and carpenter's work, but she also couldn't understand it, because there was no electronic ...... in this era

In fact, Tang Ning had already closed his mouth in time, and he hadn't said that the light used to irradiate it was not other light, but a laser. It wasn't until 100 years later that American scientists Charles Townes and Arthur Sholow discovered a miraculous phenomenon: when they applied the light emitted by neon light bulbs to a rare earth crystal, the crystal's molecules would emit a bright and always congregated light. Based on this phenomenon, they proposed the "laser principle", that is, when a substance is excited by energy with the same oscillation frequency as its molecule, it will produce this non-divergent strong light, the laser.

Electrochemical methods to reduce and polymerize gold ions in solution into nano-scale gold particles is a god-like technology, which is not enough to be humane. It's still a little reliable, he comforted the little princess again: "Actually...... Louise, even if your father is gone, it's not that terrible. The love that once existed will not disappear, and you can still see him in your dreams. A third of a person's life is spent in sleep, and your dear father will often come back to see you. Let me ask you a question: Have you ever heard of the ship of Theseus? ”

Louise shook her head.

Downing explains: "Theseus was the king of Athens in Greek mythology, and when he was a prince, Athens was defeated by Crete, and the king of Crete, Minos, demanded that the Athenians sacrifice seven boys and seven maidens to the monster Minotaur every year. When it was his turn to sacrifice for the third time, Theseus volunteered to kill the monster. He made a pact with his father, Aegeus, that when his ship returned to the voyage, he would hoist white sails.

In Crete, Ariadne, the daughter of Minos, fell in love with Theseus, and she gave him a ball of thread so that he could mark a retreat in the labyrinth. Theseus killed the Minotaur and led the rest of the Athenians out of the labyrinth, and he also took Ariadne with him, but was snatched by Dionysus on the island of Naxos on the way back. Unwittingly, Ariadne cursed him, so Theseus forgot to hang up the white sails, and the old king, believing that his son Theseus had failed and died, fell to the shore in grief and died, and from then on this sea area was called the Aegean Sea.

The 30-oared boat that Theseus and the young men of Athens took when they returned from Crete was left as a monument by the Athenians, and as time passed; The wood also decayed, and the Athenians replaced it with new wood. In the end, every piece of wood in the ship was replaced; So the ancient Greek philosophers began to ask, 'Is this ship still the original ship of Theseus?' If it is, but it doesn't have any of the original wood anymore; If not, then when did it not? ’”

Downing intends to dilute the little princess's sorrow with a large number of names and twists and turns in the storyline.

Louise: "This ...... Is it? I do not know. ”

Downing: "Plausible. Louise, you were four years old when I first saw you, so much older, (he measured his hand to a small height), but you're a big girl now. How old are you? ”

Louise: "13 years old. （http：／／.）。 ”

Downing: "Oh...... It's really a big girl. You are no longer the same you, and I am no longer the same me, we are changing little by little every day, until one day, we don't know ourselves. It is no exaggeration to say that we die every once in a while, and the goddess of death is not terrible, she accompanies us every day and lives with us. You see, you're a big girl, and it won't be long before you're going to marry far away, like your sister, to Berlin. Then, day by day, you will forget about the qiē in London, only to leave all the memories with a faint shadow. That's how we live. If someone close to us leaves, let's treat it as if we and our loved ones have gone to a distant country, maybe you want to go to Australia, Canada? New Zealand? I do not know. ”

Louise cried again: "Yes, I want to be strong, as if I am going to marry into a country that will never return home, woo woo woo ......"

She was so uncomfortable that she wanted to throw herself into Tangning's arms and cry again, but just as she was about to take action, a gentle voice came: "Huh? How did you make Princess Louise cry? ”

It was the Duchess, Louise, who was shocked, wiped a handful of tears from the back of her hand, and fled with her life.
