About 10,000 years ago, the earth was covered by ice, the glaciers melted due to the rising temperature, and the northern hemisphere of the earth was suddenly surrounded by floods of unknown origin. The mountains tremble in the waves, the land moans in the midst of great changes...

The rain was pouring down day and night...... People are desperately trying to escape...... They climbed onto the roof, but the house collapsed and threw them to the ground. So they climbed to the top of the tree again, but the tree shook them down again. People found a place of refuge in the cave, but the cave collapsed and took people's lives.

The sky was full of lightning and thunder, dark clouds, a lightning bolt crossed the sky, a huge fireball in the void fell into the flood, the moment it was submerged by the flood, it made a huge sound of stormy waves, and suddenly from the huge waves came out of a silver-white eight-clawed silver dragon straight into the sky, after circling in the air, he swooped down in the direction of the water ball, swallowed the water balloon into his mouth, the water ball was swallowed in the moment, in the belly of the eight-clawed silver dragon emitted ten thousand golden lights, and the body of the eight-clawed dragon gradually became larger, The propped up made an earth-shattering roar, the sky into the sea kept rolling and struggling, with a loud "bang", the body of the eight-clawed silver dragon finally couldn't withstand the constant surge of the body, and the stomach was exploded in the air, and the water balloon slipped from the air, intertwined with the body and blood of the eight-clawed silver dragon, the golden light gradually weakened, and the ball continued to shrink and finally became only the size of a ping-pong ball, flowing into the East China Sea along the flood.

10,000 years later, several adventurers in a deep-sea exploration activities, found a golden yellow bead on the bottom of the sea, in order to get this orb, they fought to the death with a shark, the last comrade-in-arms died tragically, the remaining explorers in order to commemorate their comrades-in-arms, donated this orb to the National History Museum, the museum came forward for the heroic sacrifice of the adventurer for a thick burial, and then by the state organized several scientists to study and analyze the orb for decades, Finally inadvertently found that this jewel actually has the energy to travel through time and space, but it must be used to use human blood to drop onto the orb to turn on this function, and the effect of different blood types of blood dripping on the orb is not the same, for example: type A blood drops on the orb, can make people instantly travel to tens of meters, hundreds of meters away, and type A blood can make people travel to thousands of meters or even tens of thousands of meters and so on.

With more in-depth research, scientists have found that the rarer the blood type, the more different the effect, and they have carried out different analyses and studies on these blood types, such as: RH, SSU, P, KELL, KIDD, LUERAN, DEIGO, WIS, DUFFY and a series of other rare blood types.

These blood types dripping onto the orb can make people travel far in an instant, even from the southern hemisphere to the northern hemisphere, these discoveries made the scientists ecstatic, they handed over the research report to the higher organization in the hope of getting greater support, the higher requirements are to avoid causing panic and riots in a large area or even the world, immediately block this news, and secretly invest funds for more systematic research, hoping that this research can make a great contribution to mankind.

Twenty years later. In the depths of a dense forest in northeast China, a pair of men and women are laughing and playing in a stream, the woman is wearing a purple coat, rolling up her trousers to reveal her charming and slender calves, bending down to hold a hand of spring water, splashing at the handsome man who is bowing his head and washing his face, the handsome man squatting, holding the clear spring water and slapping his face, was suddenly splashed with water, raised his head to see his lover, standing in the middle of the stream, a purple dress can not hide her graceful figure, Qianqianyu carefully picked up a hand of spring water, exuding a trace of charming fragrance, and looked at himself with a flower-like smile on her beautiful face, the man couldn't help but look a little stunned, and even if a hand of spring water was splashed on his body again, he didn't react.

"Zilong, what are you looking at?" The beauty in purple looked at her husband and asked shyly.

"Ziqing, you are so beautiful!" Tang Zilong replied stupidly.

"Hmph, ignore you." Zi Qing pretended to be angry, turned around and walked towards the depths of the dense forest.

"Wait for me." Seeing this, Tang Zilong hurriedly put the medicine basket on his back and chased after him.

The jungle was dense and the grass was green, Tang Zilong and Ziqing held hands and walked on the forest path.

"Zilong, look, Lin Lan." Zi Qing pointed to a few blooming Lin orchids on the hanging rock cliff not far away. (Lin Lan: also known as: Dendrobium, Wanzhang Whisker, Spider Plant, Lin Lan, Jin Haihua, etc., is a kind of precious Chinese medicinal materials, generally on the long cliff)

Tang Zilong looked in the direction of Ziqing's finger, his eyes lit up, "You are waiting for me here." After saying that, he flew a few steps, jumped to the bottom of the cliff, took out a rope from the medicine basket, threw it hard, hooked a treetop on the cliff, dragged it hard, and climbed up with agility along the rope.

Ziqing watched Tang Zilong climb up with his hands and feet, while he was a little worried, he was also sincerely happy in his heart, he knew that Tang Zilong had been practicing martial arts since he was a child, and he was athletic, and such a high cliff could still be easily handled.

"Wow, what a beautiful blue flower!" Ziqing followed Tang Zilong's direction, and saw a steep slope full of blue flowers of all colors, and happily ran forward to pick one and put it on her head.

There were a few red and yellow chrysanthemums, one, two, Ziqing held the picked flowers in her hands, and her heart blossomed, but suddenly her feet slipped, and she accidentally slid down the steep hillside, and her whole body hit a big tree Zhuangzi and stopped.

Tang Zilong climbed on top of the cliff, carefully cut off Lin Lanhua with a sickle, put it in the basket, looked in the direction of Ziqing, and happened to see the scene of Ziqing rolling down.

"Ziqing." Tang Zilong shouted his lover's name, with the help of the power of the rope, he kicked the cliff with his feet, jumped down in a few quick strokes, and ran all the way down the steep slope where Ziqing had an accident while shouting, looking at the flowers scattered along the way being dyed red by blood donations, and the frenzied anxiety in his heart stepped up, and finally saw Ziqing in front of a big tree.

Tang Zilong walked forward quickly, picked up Ziqing, who was covered in blood, took out a few hemostatic drugs from the medicine basket with quick movements, chewed them with his mouth, applied them to several seriously injured places in Ziqing, and tore off the corners of his clothes to bandage him, and found that Ziqing was still unconscious, it was estimated that she may have suffered internal injuries and needed to be sent to the hospital immediately.

Tang Zilong often goes up the mountain to collect medicine, and is more familiar with this mountainous area, so he soon came to the highway by copying the small road, waving vigorously to the passing vehicles, hoping to stop a car and take them for a ride, but several cars passed in a row, and they did not stop, so they had to put Ziqing on the lawn next to the road first, and waited anxiously.

On the mountain road, a black Humvee drove fast, with a young driver and a gray-haired old man wearing glasses sitting in the car, "Professor Lin, we will go to J City this time, how many days will it take to return?" The young driver was chatting with the white-haired old man while driving.

"It's just a chance to go this time, and I don't think there's much hope." Professor Lin replied with a sigh.

"You said that you have been working hard for scientific research all your life, and it is time to rest!" The young driver said meaningfully persuadingly.

"Xiao Xu, this research is my life's dream, I hope it can be realized before I die, otherwise I will not give up." Professor Lin replied with a firm look in his eyes.

"Professor, someone stopped the car in front of you, and there seems to be an injured person lying on the side of the road, should we help?" Xiao Xu looked at a handsome man in front of him who was waving and asked.

"It's important to save people, stop the car immediately!" The professor patted Xiao Xu on the shoulder and ordered.

"Oh" Xiao Xu responded, braked suddenly, and the Hummer stopped in front of Tang Zilong.

The professor and Xiao Xu opened the door and got out of the car, glanced at the young man in front of them, and saw his handsome appearance, tall body, and his eyes were full of anxiety, and asked, "What's the matter, young man?" ”

"Uncle, my lover and I went up the mountain to collect medicine, and my lover accidentally slipped down the hillside, can you give us a ride?" Tang Zilong pleaded anxiously.

Professor Lin glanced at an injured beautiful woman lying on the side of the road and said, "It's important to save people, get in the car!" After speaking, he opened the car door and asked Tang Zilong to carry Ziqing into the car.

In the central hospital, a black Humvee came galloping and stopped at the entrance of the hospital, and several medical staff lifted down a beautiful woman covered in injuries from the car and quickly pushed into the emergency operating room.

Tang Zilong was in front of the door of the emergency operating room, anxiously walking back and forth, next to Professor Lin and the driver Xiao Xu, the door of the operating room opened, and a doctor in a white coat walked out, "Who is the patient's family" The middle-aged man walked out and shouted at Tang Zilong.

"I am!" Tang Zilong stepped forward and said.

"Who are you?" The doctor asked again

"I'm his lover!" Tang Zilong replied.

The doctor looked at Tang Zilong and asked, "Are you married?" ”

"Not yet," Tang Zilong replied with his head down.

"The patient, the brain is bleeding heavily, he needs surgery, and he needs a blood transfusion, and now he needs the patient's family to sign, you should notify her family to come over immediately, this is the bill of expenses required for the operation, go and pay the money immediately!" The doctor explained.

"His family is in H City, it's definitely too late, can I sign it for me?" Tang Zilong asked.

"According to the procedure, it shouldn't be, in this case, you better go and pay the money first, we are discussing the signing, and now we need to have surgery immediately." The doctor urged.

"Okay" Tang Zilong responded, glanced at the bill of expenses handed over by the doctor, his hands trembled a little, and his heart became even more anxious, the bill of expenses said that the cost of surgery in the early stage alone will cost more than 30,000, plus the cost of treatment in the later stage, it will cost more than 100,000, he is just a poor student, Ziqing's family is not rich, how can he have so much money.

On the way to the hospital, he had learned that Tang Zilong and his lover Ziqing were both students who were about to graduate from the City Medical University, they were both from the countryside, their families were poor, the two of them grew up together, went to school together, and came to this university from the village together, they worked hard in school, and they had scholarships every year. Professor Lin appreciated the young couple and decided to help them.

"In this way, I will handle the signing, and I will pay you the cost of the patient's treatment first, and you will pay me back later!" Professor Lin looked at the anxious Tang Zilong and said.

Tang Zilong looked at the kind old man in front of him, he had just met him, but he helped him so much, he was moved to tears, knelt on the ground, kowtowed three times, picked up the card given by the old man and turned around to pay the money.

"This doctor, please call you Dean Lin, I have something to do with her." The old man sent Tang Zilong away with an approving gaze, looked at the middle-aged doctor next to him and said.

"Okay, wait a minute!" After the doctor finished speaking, he went to inform.

"Dad, why are you here?" At this moment, a tall and beautiful female doctor came from the corner of the corridor on the other side and shouted to Professor Lin as she walked.

"Hehe, I'll come and see my girl!" Professor Lin greeted him and told his girl about the ins and outs.

"Dad, are you really going to do this?" The tall beauty asked.

Professor Lin didn't answer, looked at his daughter, nodded firmly, Lin Xi wanted to say something, but didn't say it, she understood her father's temper, since he had decided, it was difficult to change.

"Doctor Liu, let's prepare for surgery immediately, I'll sign this word, if something happens, I'll bear the consequences!" The tall beauty looked at the middle-aged doctor who came out of the operating room just now.

"Okay, Dean Lin, I'll arrange it right away!" The middle-aged doctor replied respectfully.

"Thank you!" Professor Lin was particularly pleased to see his daughter do so.

"Dad, what are you polite to me, let's go and see what that girl rescued like this?" Dean Lin, who was still vigorous and resolute just now, heard his father say this, and immediately leaked out of the posture of a little woman, and walked into the intensive care room with his father's arm.

"Dean Lin, this is the patient's blood test report, she is a rare blood type of KIDD, but our hospital has not received such a blood type for several years, you see?" A nurse with eyes held a report and handed it to Lin Xi to explain.

Lin Xi looked at the report as a result, frowned tightly, and handed the report to Professor Lin again, because she knew that her father was an expert in this area.

Professor Lin took the report and looked at it, and said: "This blood type can be debugged according to several different blood types, but the requirements are stricter, first of all, it must be blood, followed by the age of 25 years old, and the other is also very demanding for equipment and staff. ”

"Blood still drains me!" Tang Zilong, who had just returned from paying the money, heard Professor Lin's conversation and came over and said.

"Count me in!" The driver, Xiao Xu, saw Professor Lin's family on the side just now, and he had silently paid so much to save this girl, and he couldn't bear the kind nature in his heart, so he rushed over and said.

"Count me in!" A beautiful nurse with glasses also stepped forward.

"Don't earn it yet, Bingbing, immediately notify all doctors and nurses under the age of 25 in the hospital to gather in the blood room!" Lin Xi was particularly moved when he saw so many people enthusiastically stretching out their hands, and immediately arranged for a beautiful nurse wearing glasses to say.

Ten minutes later, there was a long queue at the door of the blood donation room, all the young nurses and doctors in the hospital had arrived, and some family members of inpatients had also joined the team after hearing the news.

As time went on, blood test reports were sent to the dean's office.

"Dad, how's it going?" Lin Xi handed Professor Lin the last blood test report and asked.

Professor Lin took the report and looked at it, and said solemnly: "There are four blood types that have been gathered, but there is still one most critical blood type missing."

"Are there any health care workers who didn't donate blood?" Lin Xi looked at the young nurse who came in with the report and asked.

"Report to the dean, no." The nurse replied, "Oh, there's another gentleman, for some unknown reason, I didn't check his blood type." The nurse thought for a moment and added.

"Let's go, let's take a look!" After Lin Xi finished speaking, he took the lead in walking out of the dean's office, and Professor Lin and the young nurse also followed quickly.

"Still no results." In the blood donation room, Lin Xi shook his head and handed the blood donation report to Professor Lin.

"Could it be that he has a special blood type?" Professor Lin looked at the report and muttered to himself.

"Xiao Xu, go to the car and bring my blood test equipment immediately" Professor Lin thought for a while, and suddenly thought of something, and immediately arranged it.

After a while, Professor Lin took the special blood type blood test equipment taken by the driver Xiao Xu and Lin Xi to the blood test room, and as soon as he arrived at the door, he saw Tang Zilong sitting on the stool in front of the blood test room in a daze.

"Mr. Tang, why are you here?" Professor Lin was the first to ask.

"I don't know either, but it was a nurse who said my blood type needed to be retested, so she asked me to come over." Tang Zilong stood up and explained.

"Okay, you come with me" Professor Lin walked into the blood test room first, Tang Zilong followed in, and Lin Xi closed the door casually after entering the door behind.

"Hahaha, that's the blood type, woo woo" A few minutes later, Professor Lin looked at the blood type displayed by the blood test equipment, laughed, and in a blink of an eye, he was full of tears, and his mood was abnormal.

"Dad, what's wrong with you?" Seeing his father like this, Lin Xi walked forward and asked with concern.

"What's wrong with this old man, he will cry and laugh for a while" Tang Zilong looked at Professor Lin's abnormal reaction, and the second monk was puzzled, but he was still worried that something would happen to his benefactor, and he also asked with concern, "Professor Lin, are you okay?" ”。

"Hehehe, I'm fine!" After a long time, Professor Lin finally controlled his excitement and returned to normal.

"Dad, are you looking for it?" Lin Xi knew that his father had been engaged in a scientific research for decades, but he lacked a special blood type, in order to find this special blood type, his father had been traveling around the world for more than 20 years.

Professor Lin nodded symbolically and said, "I didn't expect the old man to find this blood type in his own place after running for so many years, it's really worth the emperor's heart!" ”。
