I, Uchiha Hikaru, have joined the chat group.

Chapter 137 Speculation on Immortal Techniques

A dozen minutes later.

Orochimaru stared into thought as he looked at the blood sample in the test tube, which had turned the color of carbonated cola.

—To be precise, it's not just that the color has turned a light black.

Inside this "cola" tube, there were still many tiny bubbles constantly condensing, coalescing, and bursting... causing fine white streaks to appear on the originally sturdy glass wall, as if it were about to explode at any moment.

"Does this liquid... always flow through Erii-san's body?"

"Yes, this is what a mixed-race blood sample looks like."

Uchiha Hikaru nodded: "If you mix it with the blood of an ordinary person, you will see a very violent explosion, producing a highly corrosive compound that can burn through a carpet instantly."

"?"

I was a little confused.

But Orochimaru had seen it all before, and he quickly regained his composure and began to conduct the tests and analyses methodically.

Uchiha Hikaru asked Erii for a bottle of serum, took out a vial, and handed it to Orochimaru along with the research data from Herzog.

"This serum was extracted from the fetuses of hybrid races that were more severely eroded. It can be used to suppress the erosion, but its main function is to promote bloodline evolution..."

That's right.

Serum drugs are essentially a type of evolutionary drug.

After all, Herzog's ultimate goal was to make Erii a vessel for the "Holy Remains" to filter out the poison and thus ascend to the White King. To this end, he needed Erii to live peacefully until the "Holy Remains" were born, and at the same time, he needed her bloodline to be as close as possible to the White King's in order to better fulfill her role as a vessel.

The serum drug produced for this purpose is actually a double-edged sword, a case of drinking poison to quench thirst.

Even without the "Holy Remains" incident, Erii's bloodline would inevitably have spiraled out of control anyway; the only difference was the timing.

Since it has been decided to involve Orochimaru in this research.

Uchiha Hikaru spent some time explaining it in detail.

"...A hybrid, a Deadpool, a dragon?"

Orochimaru narrowed his eyes: "Do these things really exist in the ninja world?"

"You can think of it as a very distant continent."

"……All right."

Orochimaru gave Erii a deep look, then turned back to the lab table in front of him and said, "I need a few days to conduct the relevant analysis and tests. During this time, I may need Ms. Erii's cooperation to undergo some examinations."

If Lord Guang is worried, he can stay and check on things, or he can move around the base freely. If there's anything you need, just let Honglian and the others do it.

"it is good."

Starting from the second day.

Uchiha Hikaru created several shadow clones, each responsible for daily training, searching for Tensei Jugo, providing pre-school training for Karin, and inquiring about the current situation of Otogakure from Guren and others. He also spent some time imprinting each of them with a seal for future use.

As for Uchiha Hikaru's true form, he remained in the cave, accompanying Erii during her treatment. During this time, he answered some of Orochimaru's questions and performed several physical examinations on Erii's behalf.

For the rest of the time, she browsed through Orochimaru's collection of books.

have to say.

Orochimaru's knowledge base is indeed very extensive.

They were completely different from the brutes within the Uchiha clan who only pursued power.

Or rather, the entire ninja world is actually this style.

Hiruzen Sarutobi, known as the "Professor of Ninjutsu," was only highly skilled in ninjutsu, but he likely hadn't read many scientific treatises. Conversely, the seemingly simple-minded and crude Hidden Cloud Village secretly overtook them, creating a chakra cannon capable of blasting a bullet to the moon just a few years after the Fourth Shinobi World War…

Inside Orochimaru's cave, Uchiha Hikaru saw rows of bookshelves.

The room was filled with numerous works on anatomy, pharmacology, pathology, and even psychology. There were also some books on mathematics and physics, but fewer in number, suggesting that these two disciplines were not as comprehensive as those in medicine.

"...Can even Master Guang understand these books?"

Orochimaru also created several shadow clones, some of which were conducting blood sample tests, while others were flipping through medical books. One of them approached Uchiha Hikari, looked at her from behind for a while, and then spoke in a low voice.

What do you think?

Uchiha Hikaru glanced to the side.

In her previous life, she had graduated with a science and engineering degree, and her grades were decent. She wouldn't say she'd understand these specialized books after just one reading, but she could grasp the general meaning. If she were truly willing to spend the time and patiently study them, understanding most of them shouldn't be a problem.

After thinking for a moment, Uchiha Hikaru pulled out a stack of books from the capsule and placed them on the table: "Here, take a look at this."

"?"

Orochimaru took it with a hint of confusion, glancing briefly at the title—

Euclid's Elements, Number Theory, Calculus, Linear Algebra...

Hmm... I bought most of these books in the Dragon Raja world.

There were a few other books that Dr. Brief casually handed to me when I visited him last time.

Orochimaru initially just flipped through them casually, but after a while, his expression gradually changed: "Lord Hikaru, did you also obtain these books from that 'friend' from another continent?"

I guess so.

"...Is there anything else?"

"want to?"

Uchiha Hikaru's lips curled slightly as he said in a half-joking tone, "How about exchanging it for a scroll from Ryuchi Cave?"

Orochimaru paused slightly, narrowing his eyes: "Lord Hikaru, are you serious?"

"certainly."

The Ryuchi Cave scroll was indeed one of the main purposes of Uchiha Hikaru's trip.

Summoning beasts were secondary; her main goal was to study the Immortal Mode of the three holy lands and see what kind of power it was.

However, exchanging a few math books for a scroll from Ryūji-dō seems a bit disproportionate...

"...Regarding the 'demons' you mentioned before, I can provide you with a few live samples; I also have a blood sample from the Uchiha clan. Using these items to exchange for the summoning scroll you possess shouldn't be a problem, right?"

Seeing Uchiha Hikaru speak again.

Orochimaru smiled. "Since Lord Hikaru is willing, as his subordinate, I will do my best... However, I must remind you first that the Ryuchi Cave lineage, with whom I have signed a summoning contract, generally has rather bad tempers. Even for me, summoning them to help each time comes at a considerable cost..."

"It's okay, I love dealing with rebellious kids."

Uchiha Hikaru smiled brightly.

Speaking of which...

"The immortal mode of the Three Sacred Lands is essentially the use of natural energy, but there is a risk of being corrupted by it in the process; while the dragons of the Dragon Clan world possess the ability to manipulate the elements of the world through their blood, and their blood can corrupt humans... Aren't these two things somewhat similar?"

Uchiha Hikaru suddenly had this idea.

"Did you think of that too, Master Guang?"

Orochimaru on the other side hissed, "I had this suspicion when you talked about the origins of hybrids. But since I don't know much about Sage Mode, I shouldn't make any assumptions."

If you are interested in this, you can visit Ryuchi Cave in the future and ask the White Snake Immortal; perhaps you can gain some inspiration.

Happy Lantern Festival everyone!
