To Hell with Being a Saint, I’m a Doctor

Chapter 74: Research

What could be used as a substitute for a lens?

Ray decided to put his stagnant thoughts aside for a while.

If he wasnt able to come up with an answer after much thought, it might have been better to give his mind a little rest.

Of course, he continued reading medical books during his rest, so it might not have truly been a rest at all.

Doing something else might have been the right thing to do.

Ray glanced at Eclair, who was silently reading a book opposite him.

They had become somewhat close and exchanged words comfortably.

Youre very diligent, Ms. Eclair.

The very person who had read books more diligently than Eclair was now commenting on her diligence.

To this, she responded with a bewildered expression.

It seems like youve read more books than I have.

Ha-ha. There isnt much discovered about medicine yet, so I must persevere.

This place.

Compared to modern times, the level of medicine was significantly lower.

Of course, it was overwhelmingly advanced in every aspect, including magic, swordsmanship, and mana.

The extremely low level of medical standards. A study that commoners didnt attempt to learn. Even the nobles didnt view it favorably.

A variety of conditions had led to the phenomenon of medicine being ostracized altogether.

Even though it could have saved many peoples lives.

Eclair looked at Ray with shining eyes.

There might not be much discovered, but if theres nothing, then we must prove it ourselves, right?

Huh?

Ray, confused, asked back, and she giggled.

Then she gestured for him to follow and started walking somewhere.

Closing the book he was reading, Ray followed her, and several hidden underground stairs revealed themselves.

Having been around her house for over a month, he hadnt realized that such a place existed.

As he followed her inside, a fragrance similar to that of a modern-day traditional Korean medicine clinic wafted through the air.

Ray looked around in admiration.

Wow. What is all this?

Dried roots and fruits were present, mushrooms were cultivated on one side, and small animals occupied the experiment stand, resembling a research facility.

She said proudly,

Ha-ha-ha. This is where I conduct my research.

He didnt need to ask what her research was about.

Anyone could tell that it was a medical research facility.

Who else would have such a facility in this different world!

Ray could tell how seriously she took medicine from the fact that she owned her own medical research facility.

And indeed, the facility was more than satisfactory, with most things well-equipped.

He felt that he could even conduct animal experiments there, something he had wanted to do.

You may use it.

She smiled at him as she looked at him.

It was as if a mother was speaking to her son.

Really?

Swallowing his saliva, he looked anxious.

Eclair giggled at his adorable demeanor.

Yes. I was lonely being here by myself.

Miss Eclair!

Why?

I love you!

His heart was completely given to the research facility.

---

Ray didnt consider returning to his mansion.

His daily routine became solely focused on research without even reading books.

By his side, Eclair was assisting with the experiments.

This is the blood of a troll. Its characteristic is that it solidifies into a squishy mass in a short amount of time.

A small amount of the green substance was poured from a small bottle, and it solidified immediately.

Ray touched the solidified substance.

Squishy - Squishy -

The touch was like a slightly firm jelly.

He thought while looking at it,

Seeing how quickly it solidifies, I understand the healing power of trolls.

The reason for its rapid solidification wasnt clear, but it seemed to be related to platelets.

Platelets were responsible for primary hemostasis, coagulating the blood.

Trolls, for unknown reasons, coagulated their blood much faster than humans, and it solidified into a jelly-like mass.

Well-refined, it seemed to be highly effective for recovery, given that it could be made into a potion.

Ray asked Eclair,

So, what would happen if this blood were injected into an animals body?

Its unrefined troll blood. It would probably die in most cases.

Saying that, he brought out a small mouse and slightly wounded it.

As a little of the trolls blood dripped onto the wound, the mouse squeaked and convulsed before it started trembling and then had a seizure.

Its dead.

While it was an obvious outcome, it was still fascinating.

Did the same laws apply in this other world?

Ray and Eclair conducted many more experiments.

Most of them involved Eclair teaching Ray the results of his research, but every experiment was several times more enjoyable than reading books.

Some animals had crimson-colored blood, and some monsters had very rough skin that was sturdy enough not to be cut by a sword.

Different animals, monsters, and other races from the modern world.

The more he learned, the more he felt the absence of knowledge.

After about a week of research, Ray discovered something fascinating.

The physical body of orcs could function without problems even when mixed with that of other races.

It wasnt just limited to organs and blood.

To test this, he roamed around the holy kingdom, looking for orcs and ogres.

Then, forced surgeries were conducted on the patients(?) without their consent.

Orcs and ogres began to show delta waves in their brains, slipping into non-REM sleep.

With skilled hands, he incised the lower abdomen of an orc.

Similarly, after incising the lower abdomen of an ogre, he took out the kidney of the ogre and replaced it with that of the orc.

With movements that would even earn the admiration of gods, the abdomens of the orc and ogre were sutured with stitches made of mana.

Now, we just have to observe their condition. Clean.

Although they struggled a bit due to the significant difference in the size of their kidneys, they managed.

After he cleaned his hands with magic, Ray wiped the sweat from his forehead and waited for them to wake up.

Four hours later, the ogre remained unconscious, but the orc awoke.

Kruk Squeak.

Just as the results in Eclairs laboratory had indicated, it seemed the orc could accept the body parts of other races without any complications.

The orc screamed upon seeing Ray.

Squeak! Squeak! Squeak!

Ray frowned at the loud snorting sound.

At this, the orcs green skin turned pale.

However, the first thing he felt was the pain creeping up his lower abdomen, causing him to scream out loud.

Aaaaagh!

As soon as he rose, in his confused state, Ray pointed his index finger to his mouth and silently gestured towards the ogre.

The ogre lay as if dead. No, considering it didnt breathe, it was undoubtedly dead.

Orcs might be known as unintelligent, but they are sentient monsters with a degree of intelligence.

He understood what Rays gesture meant.

If you dont want to end up like that, be quiet.

Like a child who stops crying at the sight of candy, the orcs big mouth immediately closed.

Ray, satisfied, muttered to the orc.

Excluding the pain, it seems there are no problems with movement Perfect.

The surgery and experiment must have been a success.

Feeling satisfied, he was about to stand when he noticed something peculiar oozing from the orcs wound.

Water?

A strange liquid started to ooze from the stitched wound on the lower abdomen.

Just as he was about to touch the wound with a serious expression, the orc panicked.

Chwik! Just save my life! Chwik!

Dont worry, I will save you. Hold still.

Ziiiiing-

A short resonance of mana, and the atmospheric mana bound the orcs body.

Unable to even scream, the orc writhed in fear, looking at Ray with terrified eyes.

The fear of not knowing what he would do to its body was evident in its eyes.

However, Ray had no intention of reopening the wound without anesthesia.

He gently touched the wound and felt something akin to water.

It had been slippery and slightly sticky, exactly like an orcs blood.

But why was it transparent?

During the surgery, the orcs blood had been a deep greenish-red.

But now it was transparent, almost like water.

The reason blood was red was because of a pigment protein called hemoglobin inside the red blood cells.

In other words, the red color of the blood was due to the color of hemoglobin inside the red blood cells.

This hemoglobin, which played a role in transporting oxygen in the blood, was an essential element that had to be present in blood cells.

But did this mean that the hemoglobin had transformed and become transparent?

Why on earth?

Of course, transparent blood was not nonexistent.

Close by, shrimp and squid had transparent blood.

Of course, it turned a light blue when it combined with oxygen, but its original color was transparent.

But unlike shrimp or squid which didnt have hemocyanin, the orc, which had hemoglobin, why had its blood turned transparent?

And suddenly after the surgery!

The orcs expression had changed moment by moment as it watched Rey, who was showing strange behavior while holding his head.

Rey sighed and released the orc from the magic.

Cancel.

Finally able to move freely, the orc opened its mouth.

Chwik! Human, I was wrong. Chwik! From now on, I wont raid the human villages Chwik!

It had been so annoying that it was making a nasal sound at the end of every sentence.

Rey slightly paralyzed the orcs wound area.

Not feeling any pain, the orc touched its wound.

Dont touch the wound.

Chwik!

The orc quickly withdrew its hand from the wound and carefully stood up.

Then it started running away.

Although it wouldnt feel pain for about three hours, there shouldnt have been any problem returning to its tribe during that time.

Watching the orc run away, Rey also hurriedly headed to Eclairs mansion.

He had wanted to research this strange phenomenon quickly.

---

Lo, Lord Savior.

Rey acknowledged the servants greetings as he rushed inside.

Eclair!

As soon as he returned to the lab, he searched for Eclair.

She, engrossed in a book in her study, offered a slight smile at his frantic voice.

Why are you calling me so loudly, little one?

Guided by her voice, Rey entered the study and addressed her.

I discovered something intriguing while experimenting on the orc.

Hm?

I transplanted the ogres kidney into the orcs body, and it accepted it without any issue.

Well, thats expected. Orcs can accept body parts from other species without any complications.

The issue is what transpired afterward!

He spoke excitedly, a departure from his usual demeanor.

The orcs blood turned transparent after receiving the ogres kidney!
