Under the afterglow of the setting sun, the city wall made of black steel bloomed with bursts of cold light, towering majestically, reaching into the sky.

"Jiangnan City ......" a thin boy with some unkempt hair, carrying a thin girl on his back, stood in front of the city gate nearly 100 meters high. Taking a deep breath, he said lightly without too much expression on his face.

The boy was a little embarrassed, his black waistcoat and his height in his early eights looked a little short and shabby. And the tall and thin figure looks even thinner in this cold wind. In front of this beast-like gate, it looks so small.

On the top of the giant gate are three gilded characters of "Jiangnan City", and on the city walls on both sides of the gate are all kinds of advanced defense systems.

"Sister, we're here. The boy slowly put down the girl on his back, the girl was more emaciated than the boy, and it was obvious that it was caused by long-term malnutrition. And when the girl was put down, she was not standing, but sitting directly on the ground, and her legs could not be supported in any way.

"Philosopher...... We've finally arrived......" The girl's voice was subtle, very weak.

"Hmm!" In order to get to the Acropolis of Jiangnan City, there are too many difficulties on the way to speak. In the heart of this fifteen-year-old boy, there were mixed feelings, but at this time, his face was still so calm.

......

"Hey, people outside the door, what are you doing here? Suddenly, the hidden monitor on the door lit up, and a man who looked like a guard appeared in the screen asked.

"My name is Yuan Zhe, and this is my sister Yuan Li, from the barren area. I'm here to get tested for the Yushen vaccine. ”

"Oh?" the guard's face flashed with surprise at first, and then his face was full of disdain: "You are from the Wasteland?

Hearing this word, Yuan Zhe's brows furrowed slightly. But calm was immediately restored. The so-called waste pickers are refugees who wander in the barren areas. Most of these refugees are dependent on people who do not have an Awakening Oracle, or who do not have an Awakening Oracle.

"I just want to know, is it possible to be tested for the Yushen vaccine here?" Yuan Zhe's tone increased slightly.

However, the guard was still full of disdain, and said, "It has been fifteen years since the Age of Barbarism came, and it is unlikely that the oracle that has not awakened is still awakened. What's more, you're just scavengers. ”

"Is it not!" Yuan Zhe said word by word, and a cold light flashed in his eyes as he spoke. Like the most powerful beast in the wasteland.

"Yes...... Is it ......" The guard was stared at by this, and since he was suddenly a little stunned, he came back to his senses and said: "You come in through the side door next to you, and someone will naturally pick you up after you come in." With that, the monitor was closed, and a small door abruptly opened in the lower right corner of the gate.

Yuan Zhe picked up his sister Yuan Li and walked in through the door.

......

After entering the door, there is a bottomless passage, and the two sides of the passage are brightly lit. The passage is made of metal all around, and it only feels a little cold when you enter.

"Ahem cough ......" may be because of the temperature difference, Yuan Li coughed a few times fiercely,

"Sister, are you alright? Yuan Zhe stopped and said in a gentle tone.

"I'm fine, we're going to end our lives of exile soon. Yuan Li's tone was still very weak, but her tone revealed excitement that was difficult to hide.

"I swore I would protect my sister well. I will definitely be able to get the Yushen vaccine. Yuan Zhe said in a firm tone, since he had a memory, he and his sister depended on each other. After fifteen years of living in exile, although my sister is disabled, she has been taking care of herself. And the last time they went out to collect supplies, everyone in the team was attacked. The two of them escaped by chance, and from that time, Yuan Zhe had a firm belief in his heart that he would go to the Acropolis no matter what, pass the test no matter what, and give his sister a place to live no matter what.

I don't know how long I walked, Yuan Zhe arrived at a hall, the hall furnishings were very simple, just a coffee table and two rows of sofas.

On the sofa opposite Yuan Zhe sat an old man, and next to the old man stood a young girl. On top of the coffee table in front, there is a small white box.

Without waiting for Yuan Zhe to speak, the old man took the initiative to speak, and said, "You are here to be tested for the Yushen vaccine?"

"Hmm. ”

"And what about her?"

"She's my sister, and I've heard that if one member of the family can pass the test, the whole family can live in the Acropolis. ”

"Come here. The old man gestured for Yuan Zhe to come over, and there was not much expression on his face. Even in the face of this pair of embarrassed and even somewhat pitiful siblings, there was not much expression on their faces. Because of this situation, he has seen too much. He knew how many of the scavengers from the wilderness would be able to pass the test.

After Yuan Zhe put his sister on the sofa, he took off his coat and draped it on his sister, looking at Yuan Li's eyes with incomparable firmness and tenderness, and Yuan Li's eyes also revealed incomparable tenderness.

"Let's get started. Yuan Zhe said slowly.

"Well......" The old man nodded, and the girl next to him saw this, took out a test strip and a blood collection needle from the small box and handed them to Yuan Zhe, saying, "You put a drop of blood on this test strip, and there will be a result in ten minutes." ”

"What?" Before arriving at the Acropolis, Yuan Zhe had imagined thousands of scenarios about the test, but he didn't expect it to be so simple now. Asking, with some skepticism, "It's so simple." ”

"It's not that simple. The old man smiled faintly and said, "This is just to test your compatibility with the oracle cell, if you can't pass this level, you are not eligible to be vaccinated with the Divine Cultivation Vaccine." ”

Yuan Zhe didn't ask much, and stabbed a drop of blood on the test paper. When the blood touched the test strip, it instantly blurred, and then the color of the red blood spots began to change.

"Is that all it take?" said Yuan Zhe, handing the test strip in his hand to the old man.

The old man didn't look up, but just took it casually. And when the test strip was in front of him, the expression on the old man's face suddenly became distorted, and the left hand holding the test strip began to tremble slightly, his eyes were full of incredulity, and he stood up suddenly, and asked in a trembling tone: "How long?"

"Thirty seconds. Being asked like this, since the girl next to the old man was cold, some of the second monks were confused.

And Yuan Zhe didn't know why, his heart was pounding, and his fists were clenched. Yuan Li, who was leaning on the sofa, was also looking at the old man with an anxious face at this time.

Silence, the scene was so silent that you could almost hear the sound of everyone's breathing. As time passed, beads of sweat on the old man's forehead were the size of soybeans, and they were pouring out.

In five minutes, the blood stains on the test strip that were originally red have turned golden.

"Incredible, incredible...... old man's lips trembled, staring at the test strip's eyes, about to pop out.

"What's wrong?" I've never seen an old man look like this, Shen Ben asked the girl.

"Huh......" The old man exhaled, looked at Yuan Zhe with excitement in his eyes, and said, "Are you really from the wilderness area?"

"Huh?" Yuan Zhe nodded. Without waiting for Yuan Zhe to speak, Yuan Li preemptively asked, "Old man, what are the test results?"

"Unbelievable. After the old man calmed down, he said, "Old man, my name is He Zheng." I don't know what to call a little friend?"

"Yuan Zhe Xiaoyou, it's unbelievable, you do it first, I'll tell you slowly. He Zheng turned to the girl beside him as he spoke, and said with a cautious expression: "Pour tea for the two guests, notify the headquarters, and prepare the S-level vaccine." ”

After Yuan Zhe sat down, he held Yuan Li's hand tightly. At this time, Yuan Li's eyes were full of anxiety and nervousness, but when she looked at Yuan Zhe again, her eyes returned to calm.

"In five minutes, the reaction of the test strip is golden. This is the first time in fifteen years. The test strip can test a maximum of 70% match. ”

"Seventy percent match?" Living in the wilderness all year round, Yuan Zhe didn't have a deep understanding of these things. Looking at He Zheng's expression just now, Yuan Zhe guessed that he could be vaccinated with the Yushen vaccine.

"The minimum standard for Yushen vaccination is 20 percent matching. With a 50% match, it can almost be said that it can be successfully vaccinated with the Yushen vaccine. And more than 70% matching, since the advent of the barbaric era fifteen years, there are very few in the entire Jiangnan City, and they can all be vaccinated with Class A vaccines without exception. ”

The more the old man spoke, the more excited he became, and although Yuan Zhe understood a little, he was still very vague about many concepts: "Class A vaccine, then what is the S-level vaccine you mentioned just now?"

"Vaccines are graded from C to S from low to high, and the higher the vaccine grade, the more powerful the awakened oracle is. Of course, the higher the level of the vaccine, the more likely it is to produce regurgitation, so the matching degree is needed here, and only the corresponding matching degree can withstand the energy of the corresponding vaccine of the vaccine. ”

"The difficulty of administering the S-level vaccine will be unimaginable, and it requires at least 80% matching. That's one in a million. No, even 100,000, one in a million. Saying that, He Zheng's old face like a dead tree trembled a little at this time.

And Yuan Zhe's heart was also extremely shocked, one out of a million, so he said that he could not only become a god, but even become a real powerhouse.

"Of course, the backlash of the S-level vaccine is even more powerful against other vaccines. If the ordinary vaccination fails, although you can't become a god again, you can at least save your life, but if the S-class seedling fails to be inoculated, the backlash will be death. ”

"What, will you die?" Hearing this, tears suddenly welled up in Yuan Li's eyes. The hand holding Yuan Zhe became a little trembling, and he looked at Yuan Zhe with worry in his eyes. In contrast, although Yuan Zhe's heart fluctuated a little, he didn't react much. Fifteen years of displacement in the wilderness area have made Yuan Zhe calm beyond ordinary people.

"Hmm. He Lao nodded, closed his eyes, and said slowly: "Although I asked Xiao Ai to notify the headquarters to prepare the S-level vaccine just now, you can also choose others." ”

Yuan Zhe looked at Yuan Li, then looked at the test strip on the table, and said, "Is it that I have been vaccinated with the S-level vaccine, and I can become a real powerhouse in the future?"

"Yes!"

"So have there been any people who have successfully received the S-level vaccine?"

"Yes, but there are no more than ten in the world. ”

"Then if that fails, can you grant me a request? Yuan Zhe turned around as he spoke, carefully wiped the tears from the corners of Yuan Li's eyes, his serious expression slowly melted, and he said with a smile: "Sister, for you, I must become stronger." ”

"If I fail to vaccinate, you have to promise to protect my sister, she has been miserable in this life. ”

Looking at this pair of sisters and brothers, He Lao's eyes suddenly softened, in this troubled world, since there is still such a real family affection, he said slowly: "I promise you, at least the old man, I promise you that I will definitely let her not be hurt in any way." ”

"Hmm!" Yuan Zhe nodded, and said decisively: "For the sake of what I want to protect, I am willing to get the S-level vaccine!"
