Early in the morning, a stranger pushed open the hospital room door and anxiously asked the doctor about Li Xuan's condition. This stranger was no one else but Li Xuan's younger brother—Li Yuan.\ Like his brother Li Xuan, Li Yuan was also an archaeologist, but Li Yuan was even more outstanding. He was well-versed in astronomy and geography, and with his extensive historical knowledge, he didn't need to do the work of cleaning artifacts but instead focused on excavation and authentication.\ Yesterday, Ouyang Zibo contacted Li Yuan, who was abroad, and briefly explained the situation over the phone. Li Yuan immediately rushed back by plane. At that time, he was working at an excavation site and had just unearthed an ancient sword when Ouyang Zibo's call came through.\ “Doctor, how is my brother? Is he okay?” Li Yuan asked anxiously.\ “Who are you?” the doctor asked, looking at Li Yuan.\ “Hello, I'm this patient's younger brother. My name is Li Yuan. How is my brother's condition now?”\ “The patient's condition is very unstable. Right now, he is extremely weak. Even a mild cold could be fatal for him.”\ “Doctor, no matter what measures you take, please make sure to save him!”\ The doctor led Li Yuan out the door and left, leaving Li Yuan to stand alone outside.\ Suddenly, the phone rang: “Master, you have a new message.” Ouyang Zibo woke up from his sleep, opened his phone, and found a puzzling message. The sender had no number, and the message was blank except for mysterious text: 'Blood-stained relic sword, recognize the master to return to its clan, absorb its essence, drink its blood. Ordinary people will die. Place Xuanyuan before the person to save his life. On a full moon night, yin and yang converge.'\ Ouyang Zibo pondered for a long time and understood a bit of the content. He thought only Xuanyuan could save Li Xuan, but the question was: what exactly was Xuanyuan? A person? An object? And whether the message was genuine or false, who could tell?\ The phone rang again. This time it was Li Yuan calling, asking Ouyang Zibo to come to the hospital and discuss.\ An hour later, Ouyang Zibo arrived at the hospital. Li Yuan immediately scolded: “You brat, defying the heavens! You actually let me wait for over an hour! Tell me, what are you planning to do!”\ “Big brother, let me explain. Here's what happened: as soon as I received your call, I took bus 444, and on the way, the bus fell into a river. Luckily, the river wasn't deep.”\ “Bah!”“Are you trying to fool a three-year-old? Even I would believe such a foolish lie?”\ “Don't believe me? Look,” Ouyang Zibo took out a rusty sword with water on it, “I fished this out of the river.”\ “I'm not joking around with you. Whether it's real or not, the main thing now is to figure out how to wake up my brother. Do you have any good ideas?”\ Ouyang Zibo let out a bitter laugh, took out his phone, intending to show Li Yuan the message, but since the phone wasn't waterproof, it short-circuited. Li Yuan also gave a helpless smile and sat down. A 'ding ding' came from his trouser pocket. Li Yuan glanced and saw a message identical to the one Ouyang Zibo received.\ “Zibo, come over and take a look.”\ “This is exactly what I wanted to show you!”\ “Impossible! Absolutely impossible! It can't be a coincidence! Could it have something to do with this sword?”\ “Maybe, we can't rule out the possibility. Li Yuan, let's go back to my place first, maybe we can ask the curator.”\ The museum where Li Xuan worked had a history of over a hundred years, and many top-tier cultural relics were on display. The older generation said that the curator had never been replaced. Many people believed he had obtained the secret formula for the elixir of life, of course, this was just a rumor. But everyone who knew the curator agreed on one thing—the curator was very mysterious, his whereabouts unpredictable, and no one knew what he was busy with day-to-day.\ Ouyang Zibo and Li Yuan arrived at the studio. By chance, the curator was also there. Ouyang Zibo took out the ancient sword he found for the curator to examine. The curator said, “Destiny! This is truly destiny!”\ “Curator, what are you talking about? Destiny? I don't understand,” Ouyang Zibo asked.\ “You are unaware, this sword is one of the Six Divine Swords from the Hongwu era. Today, you found it, letting it see the light of day again. Great events are bound to happen. Although much time has passed, the sword's spiritual aura remains, and it will seek a suitable person to be its owner.”\ “Li Yuan, don't listen to the curator. He loves making up stories. Last time we unearthed a skeleton, the curator scared Li Xuan and me, saying a bloody disaster would happen within three days, making us hide at home.”\ “Zibo, you shouldn't talk like that. As the saying goes, ‘Heed the elder's advice or suffer losses,' so be careful.” After saying this, Li Yuan laughed heartily.\ “Laugh all you want, just wait and see how I get back at you.”"The curator held this sword, noticing its divine aura, and could not hear what the two of them were saying at all; he was just touching and examining the sword.\
A cabinet somewhere kept shaking, lasting for about five or six minutes, then it stopped.\
'Zibo, go get the other sword,' the curator said, his eyes fixed on the sword in his hand.\
'What? Sword? What sword?' Ouyang Zibo feigned confusion.\
'The sword I previously gave you and Li Xuan to clean.'\
Ouyang Zibo knew he was in big trouble. He sighed deeply, left the workshop, went to the museum basement, opened a certain cabinet, and screamed.\
His voice echoed throughout the museum. Luckily the museum was closed today; otherwise, the visitors would have been either dead or driven crazy. Li Yuan and the curator came over, and seeing Ouyang Zibo sitting on the floor, Li Yuan asked, 'What on earth happened? Were you robbed?'\
'Even scarier than that—the ancient sword is gone!'\
'What! Gone?! Look carefully again, maybe it's somewhere else.' The curator almost fainted from anger.\
'I clearly put it here. How could it be gone? It's impossible that it was stolen. Only I knew about it, and I am the only one with the key to the basement door. The key has never left my side.'\
'Heaven has willed it; how can we resist? Zibo, put the sword you retrieved back. Li Yuan, you come with me to the hospital, and Zibo must come too.'\
By now it was dark, and the sky was free of stars, but a strange sight appeared: a bright full moon with six faintly shimmering stars on either side. On the left, the first of the three stars was the brightest; on the right, the first and second stars were the brightest, with the rest glowing faintly.\
The curator looked up at the sky, as if understanding something.\
When they arrived at the hospital, in the ward, the ancient sword floated above Li Xuan. Moonlight coming through the window shone on the sword, and the bloodstains on it gradually faded, revealing a brand-new sword, and its owner appeared.\
Dressed in ancient attire, resembling Li Xuan to some degree, though with longer hair, he looked to be in his early twenties.\
He held the ancient sword and pointed at Li Xuan, saying, 'You are the one chosen by heaven? Pathetic. Since you awakened me, I'll give you a hand.' The man silently chanted a spell and stabbed a sword into Li Xuan's chest, then pulled it out, but there wasn't a single scratch. "Consider yourself lucky, kid. Let me borrow your body for a while," he said, and then he transformed into a spirit and entered Li Xuan's body, merging with him. The three arrived at the hospital and found a brand-new ancient sword lying next to Li Xuan. Although it was completely new, Ouyang Zibo immediately recognized it as the sword that had been stolen from the museum. Ouyang Zibo could hardly believe his eyes, thinking he was dreaming. He rubbed his eyes and then slapped himself hard, feeling the pain and muttering, "This isn't a dream." While Ouyang Zibo marveled at the impossibility of everything, Li Yuan told the doctors to examine carefully. The room seemed calm, and aside from a few minor changes that could be noticed, only the curator observed more subtle details. "My old friend, no matter where you hide, I can find you. Even now, there's no exception," the curator whispered to himself. "Old friend, take my sword and spirit and gather the remaining two people. Don't forget our mission," the man's voice came. "Don't worry, I have always remembered," came the reply. The next day, Li Xuan woke up. The following few days were spent in the hospital, and before Li Xuan was discharged, a full-body check was performed again. Only then did Ouyang Zibo take him home, while his brother Li Yuan left a few words before returning abroad.
