The method Xiao Xiao mentioned is actually modern blood transfusion.
Since Lang has lost too much blood, he should be given a blood transfusion first to maintain the balance of blood volume in his body.
The other injuries were actually just external injuries and were not as serious as the rabbit doctor said.
As long as the blood transfusion is successful and Lang's life is saved, the rest can be recovered slowly.
But the question is, what kind of blood should be transfused in this backward world? How should blood be transfused?
The most important thing is how to ensure that the person donating the blood has the same blood type as Lang so that there will be no rejection reaction.
It is also necessary to ensure that no accidents occur during the blood transfusion process and no fatal transfusion reactions occur after the blood transfusion.
Xiao Xiao said so much, and the Rabbit Doctor and others seemed to understand it a little, but Yan Xi, who was once a modern person, heard it very clearly.
This reminded him of the history of blood transfusion that he had seen on the Internet before.
The original blood transfusions used a goose feather tube connected to the donor's arterial line.
But such a thing is too risky.
The next step is to confirm the blood type. The most basic method is similar to the blood test, but there will definitely be some deviation.
"System, do you... have any pills or potions that can cure all diseases?" Yan Xi thought of System 5555 and asked hurriedly.
System 5555 seemed to know he would ask this question. After a moment of silence, it decisively replied, "No."
His brother had warned him not to interfere in the host's love affairs again.
If the male protagonist was the host's target, perhaps he could still argue, but now the male protagonist is not the host's target, he dare not commit the crime against the wind.
Yan Xi was a little disappointed, but she didn't give up. "Then can you test our blood types?"
"This..." System 5555 hesitated for a long time, and then finally thought, "Maybe it can be done."
Testing blood type shouldn't be considered as meddling, right?
It's just a blood test.
Who cares how he uses it.
System 5555 comforted itself in this way.
"Really? System, thank you!" Yan Xi was very excited, and his joy was beyond words.
Xiao Xiao also thought of the folk method of blood test, but she was a little hesitant and afraid of accidents.
Yan Xi said, "In this situation, if nothing unexpected happens, he can only wait for death. There may be a glimmer of hope if we give it a try. Xiaoxiao, thank you for telling me this. Leave the rest to me. No matter what the result is, I am willing to bear it alone."
The rabbit doctor and his apprentice also spoke up, "We'll help you. With us here, the chances of accidents can be minimized."
"Thank you. Now all that's left is getting everyone to agree to the blood test, which is the hardest part." Yan Xi sighed worriedly, "For the sake of convenience, let's start with me."
"Okay, wait a moment, we'll prepare some earthen bowls and some water."
The rabbit doctor took a bone needle and poked Lang's finger, squeezing out a drop of blood, then poked Yanxi's finger.
Two drops of blood slowly spread in the water.
Yan Xi held his breath and stared intently, not daring to blink for fear of missing anything.
Hopefully, their blood types are the same, so he doesn't have to bother anyone else and can arrange a blood transfusion as soon as possible.
Yan Xi prayed silently in his heart, and said to System 5555: "System, start the blood test."
System 5555: "Okay."
"Testing... Ding, test completed, blood types are the same, both are type A."
Yan Xi: "..." What the hell? God bless?
System 5555: “…” I swear, I really didn’t interfere, brother, you have to believe me!
At the same time, the blood types in the water bowls blended with each other, which made everyone happy.
"Xi! Look, they've merged! They've really merged!" Xiao Xiao grabbed Yan Xi's hand, even happier than him.
Grandpa Rabbit Doctor stroked his beard and smiled very kindly, "It's really God's blessing, Xi, your sincerity has moved the God."
"Well, thank God." Yan Xi's nose felt sore, but she was crying with joy.
The odds are like winning the lottery, luck plays a big part, and we really have to thank God.
Xiao Xiao said that in order to ensure the amount of blood transfusion, several of them were also tested.
But the system prompts are different for everyone.
"Oh, unfortunately, we can't help you." Xiao Xiao looked at the bowl of water in disappointment.
"It's okay. You've already helped me tremendously. You've all taken my blood, but I can handle it. At worst, I can just eat a few more meals later and make up for it."
Yan Xi patted his chest, his expression very relaxed, as if it was just a small matter.
Xiao Xiao looked at the young man with a bright smile, and felt sincere admiration and envy in his heart.
I admire Yan Xi for loving Lang so much, and I envy Lang for having such a beautiful love with him.
Everyone prepared as Xiao Xiao said, picked up a few pheasant feathers, and used a feather tube to transfuse blood.
Xiao Xiao made a syringe out of a hollow tree branch, and then began to draw Yan Xi's blood to give Lang a blood transfusion.
This process is rather troublesome and requires carefulness and attention.
After repeated attempts for an unknown amount of time, Lang's complexion improved a lot, but Yanxi's was not so good.
Because too much blood was drawn, he felt dizzy.
Xiao Xiao wiped the sweat from his forehead and said to Yan Xi, who looked pale, "It's almost done. Next, we just need to observe his reaction quietly. Xi, you don't look well. You can go back and rest for a while and eat more to replenish your nutrition. We will watch over you here and notify you if there is anything."
"Okay." Yan Xi supported himself on the stone block and took a few steps with trembling legs. Before he walked out of the cave, his eyes went dark and he fell to the ground with a thud, scaring Xiao Xiao, the rabbit doctor and the others.
