"What do you want for breakfast?" The red sun rose, shining brightly, and Lin Feng served Mu Qingqiu hot coffee.

"Is soy milk and fritters okay?" Mu Qingqiu thought of this, she hadn't eaten an authentic street breakfast for a long time.

Lin Feng waved his hand and said with a smile: "Okay, let's go, get ready, go to the alley for breakfast!"

The three of them made a little preparation, and soon set off for breakfast, the sky was just dawn, and the city was still quiet in the city before six o'clock.

Lin Feng drove to a breakfast restaurant with the most authentic and affordable reputation and the best reputation.

When he first delivered takeaways, he often came to this breakfast shop to pick up orders, this kind of fly restaurant in the alley of the alley, there are a lot of regular customers, and he and the boss and his wife have long been familiar with each other.

The Mercedes-Benz car stopped at the entrance of the alley, Lin Feng and the two girls walked quickly, and shouted from afar: "Uncle Zhang, three bowls of soy milk, ten fritters!"

There was no response in the shop, and a haggard-faced woman stretched out her head in the middle of the night, followed the sound, and was suddenly extremely shocked: "Small, Xiaolin?"

"Haha, it's me, Sister-in-law Zhang, I haven't been here for a long time, I'm here for breakfast today. Lin Feng waved his hand and greeted the middle-aged woman.

Sister-in-law Zhang looked at him in surprise, she couldn't believe it, it had only been a few months, Lin Feng had actually mixed up with such a famous hall, dressed decently, holding the Daben key in his hand, and followed by two super goddesses who had raced against the immortals!

She was stunned for a few seconds before she came back to her senses, and asked with a smile: "Xiaolin, you are developed! These two beauties, they are ......?"

"Oh, my sister Lin Yu, and my girlfriend. Lin Feng generously introduced, "We came here for breakfast, hey, where is Uncle Zhang?"

Hearing Lin Feng mention this, Sister-in-law Zhang's sad face suddenly showed sadness, "Old Zhang, he has been dead for more than a month!"

"What? How can this be? Uncle Zhang...... Was it an accident?" Lin Feng had just sat down and hadn't eaten yet, when he heard the bad news, he suddenly felt that he had lost his appetite, no wonder Sister-in-law Zhang was even more haggard than a few months ago.

"Lao Zhang died of a cerebral hemorrhage...... He was so tired, in order to manage this small business, he got up early in the middle of the night every day, and he couldn't sleep well, so he left, and it was easy......" Sister-in-law Zhang said as she served the fritters, and Lin Feng took it over and helped to serve the soy milk.

"This man, if he says it's gone, he's gone...... Xiaolin, you are lucky, but you have to cherish the people in front of you......" Sister-in-law Zhang babbled and thought, Zhang Luo had breakfast for the three of them.

"Yes, Sister-in-law Zhang is talking about ......"

Looking at Sister-in-law Zhang's haggard face, Lin Feng couldn't bear it a little, life and death were up to anyone, Lao Zhang's death was too unexpected, he was only in his forties, such a good temper, diligent and capable, and hard-working, why couldn't he live for more than ten or twenty years?

"Brother, what do you want?" Lin Yu saw that he didn't move his chopsticks, and urged in a low voice: "Eat quickly!"

"Hmm...... I'm thinking about the lives and health of ordinary people, is there a way to protect ......" Lin Feng picked up a fritter, "The rich have money and can buy the most high-end medical services, ordinary people and even the poor, what should they do?"

"Have you figured it out?"

"No......" Lin Feng took a bite of the fritters, "Eat breakfast first!"

The uneven distribution of wealth in human society, destined to be healthy is not equal to everyone, even if it is not bad for money, there are terminal diseases, incurable situations, the uncertainty of life, embodied in disease, has always been one of the biggest threats to human beings since ancient times.

Unless...... Everyone is immortal! Just like the blood wolf clan! Never sick, close to eternal life!

Thinking of eternal life, the knot in Lin Feng's heart opened, and a glimmer of dawn shone into his heart!

After breakfast, Lin Feng sent Mu Qingqiu back, and then drove Lin Yu to school, which happened to be his class this week, which was also scheduled this morning.

The auditorium of Splendid Medical College is still overcrowded, and too many people come here just to listen to Lin Feng's class, even if it is to add a seat in the aisle, they are not tired of it.

Lin Feng stepped into the classroom with the bell, and at first sight he saw a group of people gathered together, and immediately dispersed when he heard the class bell ringing.

After they dispersed, the person sitting in the middle of the students made his eyes slightly startled, it turned out to be Princess Shirley!

How did she get here?

Princess Shirley, who was wearing light makeup, was also sitting behind the desk below, with a book and a pen in front of her, quietly waiting for him to speak.

With such a big star coming to listen to the class, how could the students, especially the boys, not be excited? Before Lin Feng arrived, Princess Shirley was the absolute focus of attention, but at this moment, her focus was on the podium, and what changed was that everyone packed up their mood and threw themselves on the podium.

Lin Feng is the protagonist of today's class!

"Let's go to class!" Professor Lin, who was empty-handed and never took a handout, came to the stage and wrote two words on the blackboard: "Eternal life!"

These only two words instantly aroused everyone's enthusiasm!

A pair of longing eyes, blooming with a fiery look.

"Excited, isn't it?" Lin Feng pointed to the blackboard and smiled, and the classmates laughed along.

"Eternal life, well, what a good wish, starting from our ancestors, probably thinking about eternal life for thousands of years, as far as the first emperor, to the richest people in all countries and regions of modern society, these people who are at the peak of power, very few people do not want to live for another 10,000 years. Lin Feng opened the conversation, and the conversation suddenly changed: "So can eternal life be realized? What means or speculations can be achieved in medicine? ”

"Teacher, I heard that a technology is being developed abroad to achieve eternal cell youth through the endless replication of telomeres in HeLa cells, so that the human body can maintain vitality and refuse aging, is this idea feasible?" Wang Yaotang proposed a direction of Western medicine research.

Not only do Easterners want eternal life, but Westerners are also obsessed with it, and what Wang Yaotang is talking about is a major topic in contemporary Western medicine.

HeLa cells are derived from a cancer patient, these cells are actually cancer cells, which can multiply indefinitely, almost close to immortality, and are cultured in medical laboratories around the world, and they are more than 100 years old and will live forever.

Using HeLa cells to study the mysteries of human immortality is exactly what Western medicine is constantly pursuing, and they believe that it is very likely to be achieved in the next 100 years!

Lin Feng thought for a moment and replied: "This idea is very brave and avant-garde, but it is too difficult, even if HeLa cells can become normal cells and achieve immortality, it is still out of reach for us normal people. How do you inject these cells into the body, do you have an immortal effect, can you guarantee that you don't have rejection, or other potentially fatal diseases?"

"Mr. Lin, what do you think of the frozen human body?" someone asked in a high voice.

"Hehe, that technology is even more unreliable, even if the body can thaw after freezing, can the brain do it? Can our memories and thoughts and emotions be frozen and thawed? Moreover, after thawing, there is still a limited life!" Lin Feng shook his head and smiled: "This is a means for some Western profiteers to grandstand, this method will never reach the threshold of eternal life, and at most a few old zombies will be created." ”

There was laughter in the hall, and Princess Shirley couldn't help laughing.

"Teacher, is the online virtual human under AI technology considered immortal?"

Without waiting for Lin Feng to answer, a few classmates booed, how can it be considered immortal, that is a program!

"Hehe, the students' concepts are more colorful than I imagined, so to get back to the point, at the level of traditional Chinese medicine, is it possible to achieve it?" Lin Feng finally said dry goods.

"Teacher, does Taoist alchemy count?" a boy said to Lin Feng's heart.

Lin Feng nodded, "Our ancestors have always dared to think and dare to do in this regard, refining the muscles and bones outside, refining the blood and qi essence inside, and there has never been a shortage of Taoist priests who have been refining pills since ancient times, trying to use the two techniques of outer pill and inner pill to touch the way of eternal life." ”

"However, the vast majority of people have unfortunately failed. Is there any success? Of course there is!" Lin Feng preached loudly, and hundreds of people under the podium were silent, all eyes fixed on his face.

"Some people may ask, who is successful? I can't tell you here, otherwise the headmaster will make trouble for me!" This caused a burst of laughter, and Lin Feng continued: "The way of alchemy is a common method of pursuing eternal life in ancient times, and it is also one of the only two methods.

"As we all know, Chinese medicine has the world's largest library of medicinal materials, including almost all living beings in the world, all substances, as the so-called everything can be used in medicine, from this point of view, what is on the earth and what is not can be included in the study of Chinese medicine, in other words, the mystery of immortality is in Chinese medicine!"

The audience was silent, everyone was carefully digesting his words, the mystery of immortality is really hidden in Chinese medicinal materials?

"You said so much, it's tantamount to firing empty cannons, and it's all deceiving students!" An inopportune voice rang out, and a young man sitting at the back of the classroom stood up.

"Who is he? Dare to question Mr. Lin?"

"It looks like it's amazing......"

The college students whispered, the young man was unknown, he didn't look like a student, he didn't look like a professor who was auditing, he didn't seem to be from Splendid College.

"Oh, what do you think?" Lin Feng was not angry, looking this person up and down, a relaxed smile hung on the corner of his mouth.

"Eternal life is impossible to achieve!" said the young man in a deep voice: "Life can be extended by a part, but something beyond the laws of life cannot be realized, I don't believe that people on earth can live past two hundred years!"

"Who are you?" Lin Feng smiled, "Do you know Chinese medicine?"

"I am Li Likun, a visiting scholar at Harvard Medical School, and I don't know much about traditional Chinese medicine, but my research direction is genetic medicine, and the structure of human DNA determines that immortality is a dream that can never be realized! Compared with other organisms on earth that live very long, we have basic defects! For example, the Greenland shark is the longest-lived vertebrate animal known, but it can only live for 400 years at most......"

"Wait, you're not right, the maximum lifespan of the Greenland shark can be more than 500 years, you have to figure this out before you question it. Lin Feng interrupted Li Likun's words.

"Impossible! 400 years is the limit!" Li retorted loudly.

"That's your limit, I've seen Greenland sharks over five hundred years old with my own eyes, Li Likun, don't use the things in the textbook to theorize with me, those are useless!" Lin Feng shook his finger, "If you suspect that there are no people over five hundred years old on the earth, I can take you to meet them!"

As soon as these words came out, the students in the audience were boiling! Can anyone really live to be more than 500 years old? And more than one?
