I was a swordsman in ancient Japan

"My story is very long." Ogata said softly, "It will take a long time to tell, please listen to me slowly."

Ogata described his previous experience in Butterfly Island, how he suffered from the "immortality poison" experience, how to find the experience of their master and apprentice, and the fact that this "deep purple" skin has expanded twice before and after, all in a concise and authentic way out.

Ever since Ogata started talking about his experience, the shock on Xuanzhi's face has not dissipated.

Ogata's voice fell, and Xuanzhi remained silent for a long time.

It was not until a long time later that the shock on Xuanzhi's face slowly turned into bitterness.

"Do you call this thing in your body immortal poison... It's a pretty accurate name. To some extent, this thing in your body is indeed like a toxin that can kill people."

"Unexpectedly... the Bianruo pill I gave Zong Hai before I left has such a great effect, helping you extend your life for such a long time..."

Xuan Zhi closed his eyes and took a deep breath.

After slowly opening his eyes, he asked:

"Xuanren... How is he now?"

"He's fine now," Ogata said. "With the help of my friend, he's settled down in Owari now."

"Really...that's good..." After finishing speaking, Xuan Zhi suddenly began to smile bitterly, "Thank you for bringing me the news about my junior brother."

"I originally... thought that I would never see Junior Brother again in this life, nor hear any news from Junior Brother again..."

"I'm really lucky...Fortunately, I strongly opposed allowing my junior brother to participate in the research on immortality. Otherwise, he, who is more upright than me, would definitely become like me. People are different, ghosts are not ghosts..."

"The study of immortality..." Ogata said in a deep voice, "The tragedy of Butterfly Island...is one of the studies you and your master have done?"

"...That's right." Xuan Zhi nodded slowly, "But Master and I are just following orders."

"Do as you are told?" A-cho's beautiful eyes widened, "Do you mean that someone instructed you to study this kind of immortality?"

"Heh..." Xuanzhi let out a few self-deprecating laughs, "Where should I start..."

Xuan Zhi raised his head and took a deep breath.

As the chest bulged little by little due to deep breathing, Xuanzhi's face slowly showed the color of memory.

After slowly exhaling the air inhaled into the lungs, Xuanzhi said slowly:

"...Since I received the invitation from Master Xianyuan, my life... no, it's my life with Master, it has completely changed..."

Gennao raised his eyes and looked at Ogata and Atachi.

"Do you know Koyasan?"

"Of course I know." Although he didn't know why Gennao suddenly changed the topic to Mount Koya, A-Machi replied honestly, "It's the sacred Buddhist mountain located in the Kansai area and founded by Master Kobo thousands of years ago."

Xuanzhi nodded.

"Thousands of years ago, Master Kobo went west to the Tang Dynasty to seek the Dharma. After returning to China, he founded the Shingon sect. Later, with the permission of the emperor, Koyasan was set as a training place for Shingon followers."

"After thousands of years of development, Koyasan has become a well-deserved Buddhist holy place in Japan. At present, there are more than 120 temples on the mountains."

"Master, me, and junior brother, the three of us are masters and apprentices who are well-known inside and outside the capital for our excellent medical skills."

"Because Koyasan is not far from Kyoto, monks from Koyasan often come to Kyoto to invite us as masters and apprentices... Mainly my master came to Koyasan to treat sick monks."

"After going back and forth, master, he gradually became acquainted with the abbot of Sengenji Temple, a large temple in Koyasan."

"Sengenji Temple is one of the best temples among the more than 120 temples in Koyasan. Its abbot, Yuanrong, is honored as Master Xianyuan because of his profound Buddhist teachings."

"Originally, the three of us, master and apprentice, should just live a life of treating patients in silence, living a life that is not rich but has no worries about food and clothing..."

"Until one day... we received an invitation from Master Xianyuan."

"He asked my master to come and treat his waist again."

"Master Xianyuan has a very serious back disease, and my master happens to have a lot of experience in treating back diseases. Therefore, Master Xianyuan often invites master to see him."

"After receiving Master Xianyuan's invitation, Master and I did not suspect him, but thought that Master Xianyuan's back disease had occurred again."

"However, after the master and I, who acted as the master's assistant, went to Mount Koya and to Xianyuan Temple, we were surprised to find that Master Xianyuan's back disease never recurred at all."

"I still remember that day..."

"My master and I were invited into a small room."

"There are only two people in the room: Master Xianyuan, who is basically healthy and disease-free, and a very young warrior."

"The young samurai didn't tell us his name, he called himself Taiko."

"After Master and I were invited into that small room, Master Xianyuan said that he had something to discuss with Master alone, so he invited me out again."

"Master, Taige, and Master Xianyuan stayed in that small room for a long, long time... If I remember correctly, they stayed in the room for nearly three hours."

"The master didn't come out of the room until it was almost dark."

"Master, as soon as he came out of the room, he said to me with excitement: Xuanzhi, come with me, and we will do research together that is far more meaningful than treating people."

"I had no idea what the master was talking about at the time."

"I am an orphan adopted by the master. The master not only has the grace to teach me, but also has the grace to nurture me. Therefore, I have always obeyed the master and trusted the master."

"So... I just agreed to the master in such a muddle-headed manner, and followed the master to do his so-called research."

"I don't need to say, you should also know what this so-called research is studying?"

Xuanzhi let out a louder self-deprecating sound, and Ogata noticed that there were tears in his eyes.

"Since then, I have completely bid farewell to the days of treating people in the clinic. I started to stay in the dark laboratory, conducting research on immortality."

"In that laboratory, there are many former doctors like me and my master."

"They all came voluntarily like masters."

"Only I was tricked and abducted by Lian Meng..."

"Every day, people with dark purple skin somewhere on their body are sent into the laboratory."

Hearing this, A-Machi raised his eyebrows suddenly, and subconsciously glanced at Ogata beside him.

"These people with dark purple skin somewhere on their body, we call them transfigured."

"The two biggest characteristics of a changer."

"One: Somewhere on the body, the skin will turn dark purple."

"Two: The body has incomplete immortal power."

"The power of immortality, according to the name you gave it, is the poison of immortality in your mouth."

"Compared with ordinary people, the body function and recovery ability of the changer are stronger."

"Mashima-kun. I think you have noticed it too? Ever since your skin turned purple, your body function and recovery ability have become much stronger than before."

Ogata nodded silently.

"At first glance, shapeshifters may seem powerful, but they all have one Achilles' heel: short life."

"All transfigured people end up with the same ending: more and more of their skin turns dark purple."

"We call this phenomenon: the power of immortality is spreading in the body."

"Because all the metamorphoses whose skin turns dark purple more and more, their physical functions and recovery ability will become stronger and stronger."

"But after the power of immortality spreads to a certain extent, all the transfigured people die suddenly without exception."

Ah-Ming's face suddenly turned white.

"Our main research task is to study how to prevent these mutants from dying suddenly."

"And then something paradoxical happened. Our research didn't start from scratch."

"After my master and I joined this research, we received a prescription."

"The person who distributed this prescription to us said: The pill made from this prescription can suppress the spread of the undead force in the body, help the body absorb the undead force, and finally save the transfigured from violent death."

"But this pharmacy is missing important parts for some reason."

"For things like pills, if you use them at different temperatures and at different times, the effects will be different."

"That prescription is missing the part that states what kind of heat should be used to refine the medicine and how long it should be refined."

"So our job is quite simple: restore this prescription and refine the real medicine that can prevent the transfigured from sudden death."

"We call this medicine that can save the life of a person who changes as a person called Bianruo Pill."

"That was really... an unbearable memory..."

"We are conducting various experiments on the morphers every day..."

"Experiment how his undead power has become today, and test whether the new Bianwakamaru is effective..."

"Once the changer dies, a new changer will be sent in in time."

"The transfigured person dies suddenly, use a new refining method to refine the transfigured pill, the transfigured person still dies suddenly, continue to use the new refining method to refine the transfigured pill... just repeat the steps like this .”

"The screams and wailing of those morphers are still vivid in my mind..."

"These changers kept begging us to let them go when they were pulled in for various experiments."

"They told me about their origins, and many of them were originally Rudos. They were basically tricked or kidnapped."

"But I was helpless in the face of their entreaties...the laboratory was heavily guarded, and during the days when we were doing experiments in the laboratory, our personal freedom was strictly controlled, and I couldn't even get out, let alone let go. These changers flee..."

"Because I was supposed to save lives and heal the wounded, but I could only watch these poor people who were kidnapped in were forced to do human experiments and then die... At that time, I felt that my whole body was about to collapse..."

"When I was really about to collapse, the master suddenly told me mysteriously: We, master and apprentice, can leave this laboratory."

"I thought it was because we didn't have to do this immortal research anymore."

"In the end, I found out that I was going to do other research."

"And it's even more cruel research..."

"I didn't know until then that the corpse of a transfigured person is extremely dangerous."

"Water polluted by the corpse of the transfigured person will be mixed with the power of immortality."

"We call this water mixed with the power of immortality purple water."

"Normal people who drink purple water will slowly turn into terrifying monsters."

"The eyes turn purple, and it has a terrifying recovery ability. It is almost impossible to kill, but it will lose its sanity and be extremely cruel. It will attack anyone it encounters."

"We call people who have mutated after drinking purple water Zimu."

Ogata narrowed his eyes slightly.

Memories of the past revived in Ogata's mind, and he recalled the group of ferocious monsters on Butterfly Island.

"Master, he is very interested in Zimu, so he took the initiative to take over a new research: throwing the corpse of a person who changes into a flowing river will pollute the river, causing people who drink the water to also change. For purple eyes."

"Our test site...is chosen on Butterfly Island."

"Butterfly Island is isolated overseas, and the residents of the whole island depend on a river for their livelihood. It is the most suitable experimental site."

"At the time, I thought this experiment was insane. If the experiment was successful, the people on the entire island would become that kind of monster."

"I beg Master, don't do this kind of inhumane experiment again."

"But master... he is completely unwilling to listen to me. He insists on taking me to carry out this experiment."

"And I...don't have the courage to refuse Master..."

"So my master and I packed our bags and went to Butterfly Island. We pretended to be a doctor who settled down on Butterfly Island. Then we quietly threw the corpse of a transfigured person and a poor girl into the source of the river."

"While doing experiments on Butterfly Island, my master and I are also continuing to study Bianruo Wan."

"Those days were extremely tormenting..."

"Every day I'm worried and afraid: If the residents on the island really become purple eyes, how should I face the innocent people on Butterfly Island..."

"Result: Not long after we landed on Butterfly Island, we suddenly received news that the experimental site was built in Ezo, and we made a big discovery: they successfully improved the Bianruo pill, so that the changer could not die suddenly."

"Until that time, I didn't know that there was also a laboratory for studying immortality in Ezo."

"After hearing the news, the master was very excited. He asked his superiors to go to Ezo, wanting to see this successful experiment with his own eyes, and then successfully obtained approval."

"Before I left, I gave the two Bianruo pills to Zong Hai who lived next to us and you should be familiar with, and reminded him not to drink the water in the river."

"If you accidentally drink Zimu's blood or body fluids, or let Zimu's blood or body fluids flow into your body, that person will vomit blood and die violently."

"Although I don't know the reason, I guess: this is probably also caused by the power of immortality."

"Because this phenomenon of vomiting blood and dying is exactly the same as those who died suddenly."
