"Actually, the kid's method is worthless, since Qin Langjun is short of blood in his body, let's just think of a way to transfuse some blood into him.

It's just that it must be noted that the blood transfused in him must not clot and conflict with the blood in his body, otherwise it will harm him, so you must find the right blood type before the blood transfusion. Lin Sen explained carefully.

If he didn't let this gang of killers figure it out, he wouldn't dare to do it, when people saw him running to tie Qin Qiong's blood vessels, who knew if they would hack him to death as soon as they were excited.

"You kid just say whose blood you want to use." Cheng Yanjin said impatiently.

"If there are Qin Langjun's direct blood relatives, it is naturally the best, if not, you need to test them one by one." Lin Sen said helplessly.

"A certain person is willing to die for Lang Jun." The group of guards scrambled to say that it was obvious that there were no blood relatives of Qin Qiong in this group.

"Well, let's test them one by one, who's going to be the first to come?" Lin Sen glanced at the group and said.

Including Cheng Yanjin, he had to be the first to go up, and he was almost going to fight, so Lin Sen had no choice but to reluctantly click on one of the guards who surrounded him just now, and motioned for him to come up first.

This guy glanced at the others very proudly, and then walked in front of Lin Sen with a generous look of death.

"Just borrow some of your blood and you'll be fine." Lin Sen said a little depressedly to this guy who was ready to be a martyr at any time.

"Oh, you can do it." The guard replied with some disappointment.

What Lin Sen has to do is actually similar to the scene of dripping blood to recognize relatives, prick the guard's finger and squeeze some blood out, and then put it together with Qin Qiong's blood to see if it blends. The conditions for this experiment were too limited, and it was unrealistic to use the cross-matching method, so I had to use this rather ancient method.

"You're lucky, your blood can be used." Lin Sen said after seeing the test results.

This first person was successfully matched, which was also a bit unexpected to him. I don't know if this guard is the O type known as the universal blood transfusion, or Qin Qiong is the AB type universal blood recipient, in short, the first test is done, so there is no need to continue tossing.

"You kid shouldn't be Lang Jun's separated blood relative, right?" While the other guards were envious of this person's good luck, they also teased a few words. Qin Qiong has always treated these guards very well, and there is no need to be afraid of him getting angry when he makes such an innocuous joke.

"In the future, so-and-so and your blood will flow together in the body of so-and-so, how can it not be a blood relative." Qin Qiong followed with a few teases, and there was actually a bit of seriousness in her words. Hearing this, the lucky guard was a little too excited to speak.

Lin Sen found a weed like wheat straw, and the hollow stem was suitable for use as an infusion tube, in order to control the speed of blood transfusion, Lin Sen chose this very small one.

The weed, which was originally not sharp, arrived in Lin Sen's hand, but it was like a metal needle, easily inserted into Qin Qiong's blood vessels.

It is estimated that it is very difficult to create the kind of metal needle used in later generations in this era of Datang, but such a top problem is in the hands of Lin Sen, and it is easy and comfortable to solve.

Of course, this is also thanks to the plant transformation system, and the weeds can always be commanded by Lin Sen in his hands, or it would be too unrealistic to use the flexible weeds as needles with his handle.

After confirming that the blood began to flow in, Lin Sen carefully observed Qin Qiong's situation, and he was also afraid of the legendary blood transfusion reaction, after all, the blood types of the two were not necessarily the same.

The originally noisy guards also immediately quieted down, their eyes staring at the blood vessels for a moment, probably having a great sense of awe for this miracle blood transfusion ability.

"Alright, let's get here this time." Lin Sen carefully observed Qin Qiong's face, the previous pale had receded, and even the waxy yellow color was a little less, and he didn't know if it was his own illusion.

But under such humble conditions, he really didn't dare to give Qin Qiong more blood transfusions, the nearly 100 milliliters of blood transfusion made him scared, and continuing to transfuse would only make him more tormented, so it was better to give up decisively.

"In the future, unless necessary, you must not use this kind of blood transfusion, and even if you do, you must not exceed today's amount." Lin Sen got some weeds, commonly known as sprouts, and put them in his hand for a while, before applying them to the wounds of Qin Qiong and the guard.

The scientific name of this kind of weed should be called thistle, which has the effect of hemostasis and anti-inflammatory, Lin Sen accidentally injured himself when he was a child, and generally picked up this weed to break it and put it on, as small as a hole or two centimeters of cut, as large as the center of the foot pierced by the glass ballast, not only quickly stopped the bleeding, but also did not have any symptoms of infection, so Lin Sen is very confident in the effect of this thing.

"Now Qin Langjun can get up and see if his body is soothed. Be sure not to get up too violently, but slowly. Lin Sen said carefully.

"I know." Qin Qiong smiled, and then slowly stood up according to his words, carefully feeling the changes in his body.

"I feel a little more strength than before, and my body is much more comfortable." Qin Qiong clenched her fists vigorously and smiled with some joy.

"Thank you for your help." Qin Qiong bowed to Lin Sen seriously, and thanked him earnestly. The words inevitably became a little more intimate.

"You're welcome." Lin Sen stepped aside, pretending to wave his hand indifferently, but in fact, he couldn't help but feel a little proud in his heart.

"Sun Shenxian is here." One of the guards who had just run out to call for someone rushed and shouted.

"Second brother, don't move, just go and greet you." Cheng Yanjin grabbed Qin Qiong, who wanted to leave, and said.

"Let's go with you." Qin Qiong persevered.

"But is that medicine king Sun Simiao Sun Immortal?" When Lin Sen saw their solemn appearance, he naturally thought of this legend. What can make the two princes so respectful is still in this Zhongnan Mountain, and I think it is this cow who is regarded as a living immortal.

"There are still a few Sun Immortals in the world." The guard next to him replied very reasonably, but he thought that this mountain boy was also a hero who saved his own Langjun, so he couldn't bear to roll his eyes and despise it by the way.

After getting the right words, Lin Sen didn't bother with this Qiu Ba about the disrespect in his tone, and hurried to see the living immortals.

The reason why Datang is so desirable in this era is that in addition to the hardness of the Tang people, Datang is also domineering to the outside world, and many heroes who are as bright as the stars, and legendary figures like Sun Simiao, are also important factors. There are too many legends about them in later generations, how could Lin Sen not be curious.

When Lin Sen followed the footsteps of the guards and walked to Qin Qiong's side, a Taoist priest who had just reached middle age was concentrating on diagnosing Qin Qiong's pulse, and a young Taoist priest next to him was standing beside Cheng Yanjin, and the two of them were anxiously waiting for the result together.

"Is this one who diagnoses the pulse Sun Shenxian?" Lin Sen asked the guard next to him in a whispered with some uncertainty.

If he remembered correctly, Sun Simiao, the king of medicine, should have been in his seventies at this time.

Although the middle-aged Taoist priest in front of him looks like he has an indifferent temperament that has been precipitated over the years, he really doesn't look like a person who is so old.
