Distinguishing Blood Types

"Mystical Palm Technique!"

Shanjian He watched Muzan with a grave expression. The other man operated incredibly quickly, using the Chakra Scalpel to remove infected flesh before healing the wounds with the Mystical Palm Technique.

Both techniques required precise chakra control. Looking at Muzan's steady hands, it was hard to imagine that they did not tremble in the slightest.

After a period of frantic work, Muzan first managed to save the critically ill patients' lives. As for their later recovery, that would have to proceed gradually.

Unfortunately, the camp did not have many medical ninja. That was a serious flaw. The scarcity of medical ninja and the difficulty of training them meant that this field was destined to remain small.

"Mr. Shan Jian Helai, since the camp does not have enough medical ninja, we need to find substitutes. I will write up the different blood types and the precautions as soon as possible."

Muzan had once obtained Orochimaru's notes. Although they contained only a few brief remarks about blood types, they indirectly proved that Orochimaru had already begun exploring the subject.

Orochimaru was currently at the border of the Land of Wind. Contacting him anytime soon was unrealistic, so they could only use his notes to create the necessary equipment for testing blood.

This was an enormous undertaking and could not be completed in a short time.

Fortunately, the war was currently in a lull, giving Konoha a chance to catch its breath.

"By the way, Mr. Shan Jian Helai is in charge of the camp's medical arrangements. You can request medical support from the rear."

"From now on, the priority will be transporting blood, along with large quantities of bandages. Please do not forget that whether it is medical ninja or supplies, our goal is to protect the patients' lives."

After being hit by Muzan's barrage of instructions, Shan Jian Helai stood there blankly for several seconds before instinctively nodding.

Konoha had its own blood bank. Blood transfusions were sometimes essential, but they carried an element of gambling with one's life, so there were not many blood bags available.

If Muzan's theory was correct, then the number of patients dying from severe blood loss in the future would be greatly reduced.

For ninja injured on the battlefield, the most lethal danger in the early stages was the various complications caused by massive blood loss.

"I'll arrange for people to transport the blood. I hope the blood-type identification machine can be made as soon as possible."

Shan Jian Helai gave Muzan a slight bow. If Muzan truly succeeded, he would save many people in Konoha.

As for arranging the medical ninja, Shan Jian Helai would still be responsible for that. After all, as a Special Jōnin who had experienced a war, he understood how to make appropriate arrangements.

The two had their own duties. During this period, Muzan was responsible for researching the machine.

Orochimaru's notes contained a method for observing genes. Muzan needed to modify it. It did not need to be overly precise, but there had to be a large number of them.

There was no time to rest next. Muzan assembled and manufactured the equipment. He needed to create the first machine, then have Konoha's rear personnel mass-produce them based on the model.

After several consecutive days, a rough model was finally completed and could be used to test blood.

When Shan Jian Helai saw the machine Muzan had made, he froze on the spot, staring fixedly at it as one sample after another was tested and the blood was perfectly identified.

To adapt to the pace of the battlefield, the identified blood would even be sorted into different storage units, eliminating the need to consume their limited manpower.

After hearing Shan Jian Helai's report, Sakumo immediately understood that the machine's creation would be tremendously useful in the war. It could reduce unnecessary casualties among frontline ninja, and he made a decision at once!

"This machine must be sent to Konoha immediately!"

"I will arrange for Elite Jōnin to escort the machine back. Muzan will return to the village with them!"

Some of the precision components could not be explained clearly through words alone. Furthermore, the war had now eased, and the Hidden Cloud Village temporarily lacked the ability to launch another offensive. Even sending Elite Jōnin back would not pose much of a problem.

Of course, this matter had to be carried out in secret.

Sakumo stared intently at Shan Jian Helai beside him. "Do not let anyone else know about this!"

It concerned the course of the war. Sakumo did not want to lose the greater for the lesser, so he specifically issued an order of silence.

"Yes, Lord Sakumo!"

Even the ninja squad escorting them did not know what they were transporting. Moreover, Muzan had dismantled the machine in advance, and only he could reassemble it.

Even news of Muzan's departure did not leak out.

As a result, Anko and Mari both thought Muzan had become so engrossed in his experiments that he could not pull himself away. Anko was furious enough to want to rush over and argue with him.

He had promised to treat her to ramen, yet he had hidden away by himself to conduct experiments!

"That bastard! Let me run into him again, and I'll show him!"

Halfway along the journey, Muzan suddenly sneezed twice. The accompanying ninja assumed he was exhausted and suggested stopping for half an hour to rest, but Muzan refused.

"What's going on? With my current body, it's impossible for me to catch a cold. Someone must be thinking about me."

They reached the village in the shortest possible time. The moment they entered, Muzan felt several gazes fall upon him. With the war underway, the village's security had been raised once more.

Quite a few Konoha Anbu were probably silently guarding the village.

Several Anbu members wearing fox-faced masks watched the group hurry into the village, their pupils suddenly contracting. Every one of these people was an elite.

"Strange. Did something happen on the front lines? But why would Elite Jōnin be returning...?"

"Lord Sakumo is on the front lines. It should be an urgent mission. Let's report to the Third Hokage quickly and not waste time."

Anbu could meet the Hokage directly, whereas ordinary ninja had to wait for notification. Seeing a group of Elite Jōnin, they knew this was no trivial matter.

They hurriedly woke the Third Hokage from his sleep. After getting dressed, he arrived at the Hokage Office.

This time, besides the Elite Jōnin, there was also one special individual—Shan Jian Helai!

"What happened on the front lines?"

At that moment, the Third Hokage prayed that nothing had gone wrong in the frontline war.

At the same time, he was puzzled. Could the Hidden Cloud Village have been driven into a corner and launched an all-out attack?

"Lord Third Hokage!"

Everyone present knew Shan Jian Helai's identity. He was a veteran Special Jōnin, and anything that could make him look so tense had to be important.

"This is the half-finished machine we developed."

There were ten Sealing Scrolls in total. A huge pile of components was laid out in the Hokage Office, leaving this hero of the Shinobi World utterly confused. Just as he was about to ask a question, Shan Jian Helai interrupted him.

"Among the ninja injured on the front lines, most die from excessive blood loss. This machine can identify blood types and greatly reduce ninja casualties."

That single sentence explained the key point. The Third Hokage had originally looked displeased at being interrupted, but his expression now underwent a complete reversal.

As Konoha's Hokage, he naturally understood the cruelty of war. Many of the wounded died simply because they had lost too much blood.

"Really?"
