The eldest grandson Wuji is very busy, since Luo Yu came to the temporary station full of stretchers, he has been busy arranging for the soldiers to carry the stretchers, and then he has to stay behind to help take care of the seriously wounded.

Luo Yu was a little unable to intervene, so he had to go to Li Shizhen, a doctor with superb medical skills who did not return to Taiyuan with the army.

With him, Luo Yu felt a lot more at ease, at least someone could deal with the emergency situation of the injured.

But Li Shizhen was also busy dispensing and diagnosing medicine, so Luo Yu planned to go back to the school captain's mansion to polish the transparent crystal he brought back and make the telescope.

Just as he was about to turn around, a lightly wounded member of the Women's Army hurriedly said at the door of the wing: "Uncle Li, Zhang Yuan is a little wrong, come and take a look!" ”

Li Shizhen dropped the herbs in his hand and entered the wing room in three or two steps, and Luo Yu also followed.

Zhang Yuan's face was pale, she was hiding on the bed, her breathing was short, her hands were unconsciously clenched, the white cloth wrapped around her neck was stained red with blood, and the blood was dripping down the white cloth onto the bed board, staining the bed board under her red.

This is the excessive blood loss caused by the collapse of the wound, she is already on the verge of shock, and if she does not receive a blood transfusion in time, she will die of excessive blood loss at any time.

But now there are no conditions and no things for blood tests, let alone blood transfusion tools, what should I do?

Luo Yu had donated plasma in another time and space, and he knew that he was a universal blood transfusion, but he didn't know if it would have changed in this time and space.

You can't watch this flower girl struggle to die in pain, Luo Yu decided to take a risk, and hurriedly said to Li Shizhen: "Sir, please stop the bleeding for her first, I'll come when I go!" ”

After that, he didn't wait for Li Shizhen to reply, so he pulled out his legs and ran out, he had to find a suitable blood transfusion tool.

But how can there be injection kits in this era? When he was in a hurry to turn around like a headless fly, he suddenly saw a Songta defender walking in the direction of the hall with a bundle of wheat stalks in his hand.

The sergeant was taken aback, and when he saw it, Luo Yu had already stepped into Zhang Yuan's room, and asked, "Sir, do you have two hollow silver needles here?" ”

Li Shizhen was stunned for a moment before saying, "Yes, what's your use?" With that, he pointed to the open roll of cloth next to the wooden bed.

Luo Yuxi said: "Great, Jin E, you go and boil a pot of boiling water, go quickly!" ”

Jin E hurriedly agreed, turned around and ran out.

Luo Yu had time to look at Zhang Yuan, who had been re-bandaged, she was breathing weakly now, if it wasn't for Li Shizhen to protect her heart with a needle, I am afraid that she would have died long ago.

took the hollow thin needle from Li Shizhen's hand, and when he saw it, he was still in trouble, this needle was the same thickness at both ends, and it couldn't be put on the wheat stalk at all.

There was no way, insert one end of the needle into the wheat rod, find a thin iron wire, and gently wrap it around the combination of the silver needle and the wheat rod for more than a dozen times, and the other end also operated in the same way, and a simple blood vessel was ready.

Jin E brought the boiling water, Luo Yu asked her to pour it into the wooden basin next to her, and then threw the made simple blood vessel into the boiling water to disinfect it.

Taking advantage of the disinfection time, I moved the stove in from the outside, and then I had to dry the sterilized straw with the fire, otherwise it would not work.

I don't know if this makeshift transfusion tube can withstand the pressure of blood, but it should be able to do it, after all, the amount of blood can be controlled by a soft straw.

When it's almost done, use chopsticks to scoop up the soaked straws, put them on the stove to dry them, and then take off their shirts to reveal their strong arms.

He had not learned nursing, but the blood vessels in the crook of his arm could still be found, so he dipped a little boiling water in a clean linen cloth and rubbed the blood vessels a few times, and it was disinfected.

Then he picked up the needle of the simple blood transfusion and slowly pierced the blood vessel, Li Shizhen next to him seemed to have understood what Luo Yu was going to do, although he had never seen such a treatment, but it was better than no way.

In Jin E's exclamation, he rolled up Zhang Yuan's sleeves and followed Luo Yu's example to help her disinfect her blood vessels.

The blood flowed through the silver needle to the wheat stalk, and it took a while to drip from the silver needle on the other side, but fortunately, the pinhole was a little small, and the blood pressure was also small, and the wheat stalk could withstand it.

Luo Yu didn't want to do it again, he kept standing by the bed and operating, condescendingly, so that the blood could pass down the straw unimpeded until it dripped to the ground.

Li Shizhen seemed to have made a lot of determination, glanced at Luo Yu, who had a firm look in his eyes, and then inserted the needle that was no longer dripping blood into Zhang Yuan's blood vessel.

Luo Yu slowly let go of the hand holding the wheat pole, and couldn't see if there was any blood flowing, so he could only judge whether the blood transfusion had worked based on Zhang Yuan's state.

After a while, Zhang Yuan's face finally returned a little bloody, and his breathing slowly stabilized, Luo Yu took a long breath, but the most dangerous time had not yet come.

If the type of blood is different, she will have hemolytic shock and then die more painfully.

However, looking at her more and more ruddy face, Luo Yu should have made the right bet, his blood type should not have changed, and the probability of having the same blood type as Zhang Yuan is a bit small.

It is really impossible to use wheat straw as a blood vessel, although it has been disinfected with boiling water, but I really dare not guarantee that it is foolproof, some bacteria are resistant to high temperatures, and boiling water is not killed.

Luo Yu could only pray silently in her heart, hoping that Zhang Yuan would recover safely, otherwise, the bacterial infection would make her worse than dead.

After Li Shimin woke up, it was already the right time, he got up and replaced the two people standing guard outside the cave, asking them to eat something and rest for a while, there were still many things to do at night.

He suddenly remembered the two stunned sentry posts in the back camp of the Turkic pioneer camp, this was a hidden danger, if they were found fainted on the sentry by the patrol, it would arouse the vigilance of the Turkic army, and then tell the Mongolian camp that tonight's sneak attack would be self-defeating.

woke up Zhang Yang and told him about his worries, but Zhang Yang smiled mysteriously and said: "Second son, don't worry, we are using drugs, they will wake up soon, they will only feel that they have taken a nap, and they will not suspect that they were stunned." ”

Li Shimin breathed a sigh of relief and said, "You guys are so thoughtful, it seems that I still have to study hard, and after the matter here is over, I will go to Instructor Xue." ”

Zhang Yang said: "Instructor Xue? You mean Xue Li? Hehe, his overall results in the generation of players are not good, but the blasting project is okay, you should follow our Instructor Luo. ”

Li Shimin said: "Okay, I'll go back and ask you Instructor Luo if he is willing to teach me." He looked at the sun and said, "Isn't it time for you to go?" ”

Zhang Yang said: "We haven't been to the mountains and forests in this area, we should really go over and have a look earlier, second son, you rest for a while, I'll wake them up." ”

Looking at the backs of the three team members in the distance, Li Shimin no longer had the feeling of sleep, this time he went deep into the tiger's den, not so much to divide the Mongolian coalition army, but to learn how to fight behind enemy lines, with such a good teacher to take with him, isn't it better than simple training?

It was getting dark, after dinner, it was time to set off for the destination, and the more than 20 people who had rested for a day were all alive and well, waiting for the later show.

Starlight, today is June 16, the full moon is in the sky, and the residual heat of the hot summer has not faded in the evening.

The soldiers in the Mongolian camp seemed to be very intolerant of heat, and one by one they took off their suits, stood shirtless with spears, and stood listlessly in the open area to blow the wind.

When Li Shimin and Zhang Yang and the three of them converged, seeing Zhang Yang nodding at him, he knew that their task was completed, and the next thing was the time to kill.

A fiery bomb was particularly dazzling in the darkness, and the bare-shouldered Mongolian soldiers who had not yet figured out what the situation was, the dazzling fire flashed, and a loud bang came, and countless black spots were ushered in front of their eyes, and then they didn't know anything.

More than 20 people each carried ten grenades specially made by Luo Yu, with carefully screened half-catty granules of black gunpowder with egg whites and grains, mixed with fine iron nails, and the shell was made of one-inch thick coarse porcelain, and the explosion effect was much better than before.

Chaos arose, and Li Shimin ordered every group of two to disperse and sneak around, and then fight separately, and after scattering all the bombs on his body and throwing them into the Mongolian camp, regardless of the outcome of the battle, he must immediately withdraw to the designated mountain pass.

For a while, the fire flashed, and there was smoke everywhere, and when the Mongol soldiers rushed to see what was smoking, the bombs exploded, and several more lives were harvested, and the wounded were in great pain and wailed all over the field.

A cavalry saw that there was movement here, and hurriedly drove the horse to the rescue with torches, and the leading general was dressed in black armor, his face was like yellow paper, his long hair and beard were like snow, he was not wearing a helmet, and his white hair was scattered on his shoulders, and his white hair fluttered wantonly as the war horse galloped.

The men and horses behind were all dressed in general clothes, but they were much younger, and the sound of explosions came and went, in addition to human stumps and tent fragments, there were also grain, grass, and weapons flying everywhere after the sound.

When the general saw the soldiers in Turkic uniforms, they were throwing smoking bumps, and he trembled with anger, and without waiting for the cavalry behind him to follow, he slapped his horse forward, and smashed his head with a mace in his hand.

Li Shimin happened to have a lit bomb in his hand, and seeing that the person who came was fierce and abnormal, he didn't have a spear with him, so he had to throw the bomb at the white-haired general, which happened to hit the mace.

The two were only three feet apart, and at the moment of the explosion, Yu Dong, who was in his group, jumped and threw Li Shimin to the ground, and with a "boom", the old man stepped off the war horse with him and fell in a pool of blood, and the hard mace was blown up and thrown backwards, knocking down several cavalrymen who followed.

Li Shimin was also dizzy by this close-range explosion, he shook his head vigorously to make himself sober up, glanced at Yu Dong, who was motionless in front of him, and hurriedly stretched out his hand to help him up.

Who knew that Yu Dong's back was full of blood, and he should have been injured by the explosion, Li Shimin roared, and Zhang Yang and Lu Xiao jumped over.

Seeing this scene, where else did they care, and after quickly throwing two bombs into the rushing cavalry, they didn't look at the effect, one of them helped up Yu Dong, who didn't know whether he was alive or dead, Li Shimin stood up and followed the three of them to rush forward.

The explosion sounded, the men and horses screamed again and again, and the denser the military formation, the greater the damage, which the Mongolian cavalry understood a little late.

The sound of explosions continued, and Li Shimin saw that the effect had been achieved, so he didn't care whether he had used up the bomb or not, and whistled a few times in his mouth, indicating that he could retreat.

When the last Songta defender came to the retreat mountain pass, the Mongolian cavalry cleared a way to chase over, Lu Xiao did not talk nonsense, and after Li Shimin and they retreated to the corner, they lit the last two bombs on their bodies to blow up the mountain pass and prevent the pursuers from continuing to follow.

The Turkic pioneer battalion saw that the Mongolian military camp was in flames, presumably the camp was attacked, and hurriedly brought troops to the rescue, and when they first arrived, they ran into Lu Xiao and blew up the mountain pass.

Where had the war horse heard this loud noise so closely, coupled with the impact of the flying gravel and sound waves, it had already lost control and galloped forward, colliding with the pursuing Mongol cavalry.

The Mongol cavalry lost its commander, and the deputy commander took over the command, and after the two loud noises just now, there were thirty or forty casualties, and they wanted to control the war horse but found that they could not do anything, so they had to let it run forward.

The narrow mountain road was met by the Turkic cavalry rushing to the camp, and when there was nowhere to vent, the enemy could not wait to send him to death, and he no longer tried to control the horse, but raised his mace and killed him with the help of the galloping war horse.

This senseless massacre of the Turkic cavalry was inevitable, and the horsemen of the rear team were less affected by the sound, they barely controlled their horses, turned their horses, and retreated, not because they were afraid of death, but to bring back the bad news, and tell their generals that the Mongols had betrayed the alliance and killed them.

Luo Yu was still standing in front of Zhang Yuan's bed to give her a blood transfusion, but he said to Li Shizhen, who was staring at him: "Sir, this junior of Chinese medicine will tell you one by one later, how are you doing first?" ”
