And Subaru won't have Return by Death in fanfic.Chapters 1 to 6 consists of training arc and original time line of Re:zero starts from Chapter 7. But I strongly recommend you to not skip them or you will be confused.
Hope you guys enjoy it.
"Dialogues are shown like this" and 'thoughts like this'.
Chapter-3
"So there is still hope for my isekai adventure. I thought I should go back to my plain and boring world again." Asked Subaru hopefully.
Bai Xiaochun just stood there silently without answering for a few seconds. Just as Subaru was about to speak again, Bai Xiaochun asked him, "Subaru, there is no such thing as mana or Qi in the world you came from, right?"
Subaru was perplexed why such a thing matters, but he still answered "Yeah if someone says such things exist in my world he would be treated as a chuunibyou."
Bai Xiaochun doesn't know what this chuunibyou is, but he got the answer he is looking for. Sighing, he said, "Subaru, I am sorry to say this, but no matter how much you try, at most, you can reach the power of normal solider in that world."
Subaru got both shocked and angered by this revelation. He shouted "Hey, this got to be a joke ! This should be a joke, right? If not, what the hell am I supposed to do in another world?"
After his outburst, Subaru got depressed so much that it can be seen in his slumped posture. He calmed himself and asked, "Why is it not possible for me to become an overpowered protagonist?"
Seeing the kid getting depressed, even Bai Xiaochun felt bad. But he still answered, "The answer is simple. From what I can see, your body is not adapted to mana since there is no such thing in your world. So your aptitude in magic is pitiful. Whereas in the isekai world, as you put it, every being from the moment of birth is nourished by mana. So the average strength of people there is way high above your world."
Listening to this explanation, Subaru felt like he got duped by the light novels he read. If he was still in his original world he would even consider suing them. Just as another bout of depression was about to hit him, what seemed to be a voice of god saved him.
"But there is still hope for you kid to become the strongest. Thank your lucky stars that you met me today. Hahaha." Bai Xiaochun laughed smugly saying this.
Listening to this hope returned to Subaru's eyes as he asked, "Y-you, you would help me?"
Bai Xiaochun turned his face towards stars in the distance, releasing his aura to make him look ethereal, and gave a sigh to add some mysterious effect, he glanced at that kid from the corner of his eye. Seeing the kid staring at him with awe, he knew he got the desired mysterious expert effect. Bai Xiaochun continued
"Of course kid. As fate would have it, just as I was thinking about taking a disciple, you were presented before my eyes. So if it was okay with you, I would take you in as my disciple. Even though I may not look like it but I am the strongest being alive in the present universe." Bai Xiaochun said with a smile.
Subaru felt like dancing with joy, he immediately bowed to the man before him and said, "I will be in your care. Please take care of me, sensei."
Even Bai Xiaochun felt happy hearing this. Even though he is someone who lived very long, in his life he only got one disciple, Bai Hao. People felt that he was not suited for teaching, saying that he was too carefree and irresponsible, despite how Bai Hao turned out to be one of the strongest beings and an even greater alchemist.
Seeing his second disciple bowing before him Bai Xiaochun thought to himself, 'Just wait until my second disciple completed practicing that technique. Every person would come to my doorstep begging to be my disciple. Haaa…. I would get so many lackeys..*cough*.. filial disciples who would do any work for me.'
He is jealous of seeing others experts flaunting how great their disciples are and how much their disciples revered them, even his wives forbid him from passing his wisdom to his sons and daughters. He can only teach his sons and daughters in secret because his wives felt that he would be a bad influence on them. Come on, it was not his fault that he created a potion that turned the world into cotton candy, or maybe it was.
Coming out of his musings he took a good look at the young man in front of him. His eyes softened, like a father's eyes when they see their child. He put a hand on Subaru's shoulder and said, "Get up, since you are now my disciple you should address me as 'Master Bai', are we clear on that?"
"Yes Master Bai, please teach me well. Oh man, I can't wait for the day I would one-shot anyone just like the famous cape baldy of our world." Replied Subaru enthusiastically.
"Hehe. Good. Now close your eyes. I would be bringing you to a place where I would start training you."
Subaru doesn't understand why he should close his eyes, but he did it anyway. Suddenly he felt like he was on a rollercoaster.
After some time he heard a voice "Okay now you can open your eyes." With anticipation, Subaru opened his eyes. And he was awestruck by the scenery before him. He is standing on what appeared to be a floating island. There is a mountain range extended before him which looked like a sleeping dragon. The island is surrounded by a sea of stars which only added to the mysteriousness of this place.
While Subaru was checking the scenery before him, he heard his master calling to him "Okay, you have all the time to check this place later. For now, I will take you to the residence where you can rest. I will tell you details about your training tomorrow."
With this Bai Xiaochun put his hand on Subaru's shoulder. Then they started floating in the air. While Subaru is excited at his first ride in the air, they started to go deeper into the mountain range and stopped before what looked to be a mansion.
Subaru was staring silly at the mansion. When he is standing at the gate of the mansion he could not even see where it started and where it ended. Heck, he couldn't see how high this mansion even is.
Bai Xiaochun is feeling smug when he saw Subaru's dumb face staring at the impossibly large mansion. After all, it is his duty as a master to show his student how big the world truly is and earn some admiration in the process. He waved his hands and the large gates of the mansion magically opened by themselves . Then he called out to this student "Come on, let's enter." Subaru just dumbly nodded and entered the mansion.
After Subaru entered the mansion, Bai Xiaochun said "My disciple, this mansion belongs to your master. The first two floors are residential while on higher floors there is Spirit Chicken Dungeon. You can take any room you like on these first two floors."
"Wait a minute. What do you mean by spirit chicken dungeon?" asked a flabbergasted Subaru.
"We will talk about the rest of the details tomorrow. For now, you should rest."
Heeding his master's advice, he selected a random room and it is just as he expected. It is a room full of luxury that would put even the most luxurious rooms in his previous world to shame. After changing into comfortable pajamas from the closet, he directly collapsed into the large bed in the middle of the room and drifted into sleep.
The next day, after having breakfast with his master, Subaru was now standing in a valley excited to listen about the details of his training.
Sensing Subaru's excitement, his master just smiled and said "Subaru, you have very little aptitude in magic, so teaching you magic directly would only be detrimental to you in the long term. So I will be teaching you another technique, it is not only one of my strongest techniques but also most difficult to complete training."
Hearing this Subaru said "But Master Bai, didn't you say I don't have that great of a talent. So how can I learn the hardest technique you have."
Bai Xiaochun replied, "A perfectly normal question to ask. But the thing is, your talent is irrelevant to this technique. The only thing that matters is your determination and hard work."
'So that is why the master is confident I can become strong even with my poor talent. All my life I have been a disappointment to others. But I would make master Bai proud by mastering this technique. No matter how hard it is, I will not give up.' Subaru made up his mind. If the person known as Natsuki Subaru has a quality that sets him apart from others, it would be his stubbornness. And it would be the one that lets him complete this very hard technique his master had for him in the store.
Seeing the determination in his student's eyes Bai Xiaochun smiled and said "The technique I am going to teach is a body refinement technique. It can also be said to be the most orthodox technique known to mankind since ancient times." Suddenly his expression become serious, he continued "Subaru, before starting you teaching this method you should promise me that you wouldn't teach it to someone else without my permission"
Seeing how serious his master his about this matter Subaru gulped and nodded "Yes Master, you have my promise that this technique would only be between you and me."
Seeing his student's sincere expression Bai Xiaochun is satisfied and continued "The technique I am going to teach you is called 'Undying Live Forever Technique'…."
