doctor knife in hand

Lu Jin remembered that the earliest blood transfusion experiment in human history was to draw blood from a healthy dog ​​and inject it into the vein of a dying dog who had lost too much blood, and the dying dog gradually came back to life.

Lu Jin intends to follow suit, but blood transfusion is different from penicillin production, which is extremely dangerous.

Lu Jin's current reputation can be said to be well-known to every household, and many doctors have followed him as an example, especially those who accompanied him in the treatment of epidemic diseases, highly respected him.

He was afraid that once he started to conduct blood transfusion experiments, everyone would follow suit. Without sufficient medical knowledge and understanding of blood, it would be very easy to kill people.

Therefore, he put it in the British government quietly.With him are two apprentices, two sisters, and the British government guards who helped.

In order to prevent struggling, Lu Jin stunned the strong and healthy dog ​​in advance, handcuffed its limbs on a wooden board, and then connected the veins of the two dogs with this blood transfusion equipment. The catheter is not transparent, but it can still be seen The tube darkens as the blood flows out.

Everyone was staring closely at the dying dog, and those eyes that were about to become distracted revealed the longing for life.

Lu Jin checked the connection and found that there was blood oozing out.This is because the needle of the syringe is much thicker than later generations, and it can barely penetrate into a thicker vein, but it still hurts the blood vessel a little.

The dying dog moved suddenly, and it seemed to feel pain.

"Did he come back to life?" Lu Yao kept looking at the dog, "Look at his eyes, he is alive."

"Yes, you've regained your energy, Master." Sun Bai looked at Lu Jin excitedly.

Lu Jin said, "Go and feel its pulse, and check its pulse."

Sun Bai immediately went forward, brushed off the dog's fur, and pressed it against his neck.He felt it quietly, then turned around and said, "Master, the pulse is much stronger than before."

He Lan continued: "Is it possible to stop the blood transfusion?"

Lu Jin looked at the other dog, calculated the approximate blood transfusion volume, and then nodded, "It's ok."

The syringes on both sides were pulled out, and the bleeding was stopped for both dogs. One was obviously lethargic, but the other, which was dying, was able to whine and even tried to stand up.

"Does this mean the blood transfusion is successful?" Lu Yao asked, "Can it be used on humans in the future?"

Lu Jin asked the two apprentices to put away the equipment and boil it for disinfection later.

Facing everyone's questions, Lu Jin said: "No, this is just an example of a dog experiment, showing that blood transfusion can save lives, but the situation of humans is much more complicated than that of dogs. I just want to know that this equipment can be used."

Looking at the confusion on the faces of his sisters and apprentices, Lu Jin originally wanted to explain the difference between human blood types. Different blood types are prone to hemolysis and rejection, which can lead to more serious diseases and endanger life.

But suddenly thinking of Song Heng's question about himself, he suddenly became a little worried, whether the knowledge that was too advanced would arouse their suspicion.

"Then why?" He Lan asked, "Can't we use this method to treat people?"

He looked at Lu Jin puzzled, eager to get an answer.

Lu Jin's face was complicated, and everyone looked at him curiously, as if they were certain that Lu Jin knew about it.

"You...you never thought about why I know so much?" Lu Jin is not a person who can hold back his words, so he finally asked.

Lu Yao laughed when she heard the words, "A Jin, I have spent the longest time with you, I thought about it, but I think you must have an adventure that I didn't know about."

"Grandfather and daddy are not as good as you, but that's a good thing. The Lu family is glorious. As for why, you don't want to say that we don't ask if it's right." Lu Xin's thoughts were simpler, "You just need to be Ah Jin."

Sun Bai and He Lan glanced at each other, and said, "The more the master knows, the more the apprentice will learn. Nowadays, there are so many people who want to worship you as a teacher, but you don't accept them. Alan and I are very lucky."

"Master, you are the best master in the world." He Lan said with a smile.

Hearing this, Lu Jin took a reassurance that as long as the people around him believed in him, he would not be able to control others.

"Okay, let me tell you about the human blood type. Blood transfusions with different blood types are very prone to rejection and hemolysis. The human body will heat up, and the blood vessels will have a burning sensation. A large amount will cause life-threatening, and it is easier to die than no blood transfusion. But now I have no way to distinguish people's blood types, so once the blood is transfused, it is a gamble for life, try not to lose as much as possible. Still, it doesn't matter if you don't understand, just keep it in your heart..."

"So in the future, if a patient is forced to need blood transfusion to save his life, it is the same as surgery. We must also explain the worst outcome to the family and sign a consent form. In the future, some of us will be able to distinguish blood types and match blood of the same kind With blood transfusion, the success rate and safety will be greatly improved, which is a discovery that benefits people."

Three days later in the morning, at the city gate

Song Huai and Song Tong are arranging for the guards to check the casual carriages and horses again and check the route.

Behind him, the sisters of the Lu family brought Lu Yanze to see him off.

Lu Xin straightened Lu Jin's clothes, his eyes were filled with reluctance, "Have you brought enough bank notes? Is there any shortage of food and clothing? The north is much colder than here, so be careful not to get caught in the cold."

Lu Jin nodded, "Second sister, Uncle Fu has already taken care of it, there is enough for the road, don't worry."

"How can you not worry, there is always war there. A Jin, you are a doctor, and your sword has no eyes, so don't be brave enough to follow." Lu Yao put her arms around Lu Yan and said, "Yan'er is still young, you are his reliance , is also our reliance, you know?"

"Sister, don't worry, Song Heng is there, he won't let me have anything to do." Lu Jin smiled, then knelt down and pinched Lu Yan's face, "At home, listen to the second and third aunts, and uncle will tell you when he comes back. You bring presents."

Lu Yan nodded heavily, "Yan'er must be obedient, uncle be careful on the road."

"Good." Lu Jin patted his head, suddenly he thought of something, and said to Lu Yao, "By the way, Third Sister, the Crown Princess is about to give birth. If the Crown Prince comes to order, you will enter the palace to help the Crown Princess give birth."

Lu Yao said: "Understood, you don't need to worry about it here."

Sun Bai and He Lan also followed the master, and the two sisters couldn't help but ask a little more. "It's the same with you two boys. Be careful when you go out, you know?"

The two boys saluted Lu Xin and Lu Yao respectfully, "Second Senior Aunt, Third Senior Aunt, Junior Junior Brother, don't worry, we will take good care of Master."

"It's getting late, let's go." After Lu Jin finished speaking, the three got on their horses.

A month later, Lu Jin and the others arrived at the border.

Along the way, the closer to the north, the more intense the atmosphere of war, and the people in the border cities are talking about this war.

Although Qiang Rong captured the two cities of Yancheng and Lucheng, and captured Shaping City before Song Heng arrived, the people of Shaping City abandoned the city early in the morning under the arrangement of the Northwest Army and moved to other cities. All the materials that can be taken away are taken away, and those that cannot be taken away are also reduced by fire.

When the Qiang Rong attacked and opened the city gate, what they got was just an empty city.

The Qiang Rong managed to capture it with great difficulty. It would be a pity if they gave up, but the occupation would waste their troops and food in vain. Compared with the Great Chu, the Qiang Rong had fewer people. Finally, after Song Heng arrived at the northern border and regrouped his troops, the Qiang Rong again Before the big Chu army surrounded him, he left with hatred.

With the recapture of Shaping City, the Great Chu made an all-out attack, the situation on the battlefield began to tilt, and the Qiang and Rong retreated steadily.

Even Lucheng, which was finally acquired, was returned to Da Chu's hands, and a group of Qiang Rong soldiers' heads were harvested.

Now only Yancheng has not been recovered, and Yancheng is the last city in the north, behind it is the high mountain plain, and beyond it is the Qiangrong desert grassland.

At this moment, King Qi's heart is shattered, and there are only two roads in front of him.

One guarded Yancheng, but with the army in Song Heng's hands, once it surrounded Yancheng, it could not last for a few days even if it did not attack and relied on the supply in the city. In the end, the city was broken and captured, and King Qiangrong no longer wanted to fight.

Different from three years ago, now Song Heng has been ordered by the imperial court as the Marshal of the Three Armies, and all the soldiers of the Great Chu obey his orders. He probably has been aggrieved by the epidemic for a long time in the capital, but when he arrives at his own base in the northwest, he is aggressive and unstoppable. The Qiang Rong who beat the ground retreated again and again.

King Qiang Rong still has lingering fears when he thinks about the previous encounter.

So Qiang Rong wanted to escape.

The other way for King Qi is to follow Qiang Rong back to the grassland.

King Qi was used to being pampered and pampered. He drank the smelly goat's milk, ate the smelly mutton, shared meals and slept in the open on the grassland. How could he bear it.

Besides, who would treat him like a guest?

Whether to eat sand and drink the wind together, or go back to wait for the trial, King Qi has a hard time making a choice.

At this time, General Qiang Rong found him.

"His Royal Highness King Qi, you have seen the situation on the battlefield now, our army has to leave, but I don't know what your plan is?"

"It's either a bereaved dog, or a confined sheep."

"Do you regret it?"

At this question, King Qi turned his head coldly, "Regret? Of course this king regrets, regretting that he didn't act forcefully."

"Okay, His Royal Highness King Qi is a true hero. My king sent the last general here to discuss something with His Highness. If the matter is successful, His Highness's great cause is still expected to succeed."

King Qi looked at General Qiang Rong, narrowed his eyes, and asked suspiciously, "What do you mean?"

The general whispered in his ear.

King Qi frowned thoughtfully, "How can you be sure that Song Heng will come?"

"Everything is just a gamble. Even if Song Heng can't be fooled, it's fine if he can kill one of his generals. It all depends on how His Highness acts."

King Qi's eyes showed hesitation, and he suddenly asked: "Why didn't King Qiang Rong discuss with this king himself?"

The general chuckled, with deep meaning in his eyes, "His Royal Highness is no better than before."

When King Qi heard the words, a surge of anger burst from his heart, and he saw contempt in the eyes of General Qiang Rong.

Knowing that he has no use value in their eyes, maybe there is, that is, they can use him as a bargaining chip when they cannot escape.

"I heard that the old emperor of Chu woke up and issued a death order to arrest His Highness and return him to the capital. I don't know what will be waiting for His Highness?" the general said.

King Qi closed his eyes, now that all his family lives are here, there is no way out.

The author has something to say: Let's end the countdown and turn to the last map. I don't know if it can be finished on May Day, hehe
