บท 42: 13th Stage
Time passed since the engagement incident where it ended with Yin Liang apologize for a whole day and even his brother Yun Qian followed suit to ask for forgiveness.
Yin Yu days normally passed where he has gone back to travel with his mother and now accompanied by his father to train.
It can be said that Yin Ying and Yin Liang want to teach every survival skill they know of to Yin Yu. They have taught him how to efficiently run away, how to read enemy movements, how to look at the enemy trail, how to detect someone with his senses, how to fight without a weapon, how to cook and the others.
Although all of it was important, Yin Yu still confused why does he need to learn how to cook since cultivation world has the so called fasting pills, and when he asks this question, his parents laugh while saying.
"Fasting pills might let you full in an instant, but you mustn't go and rely on it since it's not that healthy for a cultivator. In the first place, fasting pills was created to let a fat person becomes full, so he can gradually slim down by not eating any food, which was why it's the best medicine to lost weight and also the food which can sustain you when you didn't have time to eat."
"But it's preferable to eat cooked dish since the beast qi contained inside is nutritional for us cultivator, there's also once a cultivator go in close up cultivation, and as a result, he becomes skinny with only bones left on his body. You didn't want to become skinny until only bone left in your body right?"
Hearing the words his parents say, Yin Yu can't help but imagine him become skinny and only his bone can be seen on his body, which is not cool at all! which was why he started to seriously learn how to cook. But, Yin Yu has finally realized something after he tries to cook and it's the fact that he didn't have any talent for cooking at all!.
No matter what he does, even the simplest dishes will become miserable in his hands. He can make something like Burnt meat, but he can't even make any single decent meal, for even his parents give up teaching him how to cook.
***
Days went on with Yin Yu training.
Although he sacrifices his cultivation time, he's still improving from day to day where he breakthrough to the 9th stage of body tempering and full circle of body tempering (10th stage) respectively in few months.
At first Yin Yu thought that full circle of body tempering refer to 12th stage of body tempering but when he heard his parents say that he has already reached full circle of body tempering when he's just on 10th stage he can't help but ask his parents whether there's 11th stage or 12th stage, yet when he asked his parents this question, his father only sternly look at him and say.
"Don't ever try to break through to 12th stage and don't even think of breakthrough to 11th stage in any cultivation realm you are in later in the future."
"Why?"
"Although entering 11th stage will let you become stronger than the others, it'll also corrupt your mind and twist your worldview without you realizing it.
Entering the 12th stage will let you have strong power, but you'll cut your emotion everytime you reach it where you'll not be you anymore."
"Then…is there 13th stage?"
"13th stage is…."
Hearing the question, Yin Liang can't help thinking whether he need to answer or not, yet Yin Ying who's beside him start to answer Yin Yu question.
"13th stage is more like a legend."
"A legend?"
With a nod, Yin Ying starts to explain everything she knows about the 13th stage to her son.
"It can be said Yin family is one of the family who knows about the 13th stage for which the first matriarch of Yin family has reached that stage in her life."
"Yin family first matriarch?"
"Yep, the first matriarch of Yin family Yin Yin."
"In her time, she has once reached the 13th stage in every realm and becomes so strong, stronger than anyone else in the world and… an incident happened when her husband died killed by someone plot."
"When she heard that her husband has died, an unpredictable rage run through her and from that day, she becomes a devil."
"She kills all of her clan members just because there's someone among them who join together to kill her husband."
"She decimated a kingdom, and even her friends who live in that kingdom was killed by her without mercy just because her enemies run and hide on that kingdom."
"It can be said she's killing everyone she can see and even when her revenge has been finished, she's still killed and kill without stopping, day by day, experts from all around the world were working together to stop her yet most of them died or heavily injured in the process. until one day…when the baby inside her was almost born was the day where her sanity returns to herself."
"From that day, she lives with guilt in her heart for she has accidentally killed her parents, her friends, and even countless innocent people just because she goes berserk."
"It needs to be said that she's a kind girl before which only try to become strong to protect everyone she cares. for which she becomes guilt-ridden and hide in this lower world."
"She has gone to this realm, to take care of her sole child, and from then on Yin family starts to exist in this world."
"Which was also why, she sternly warns us never to try to reach the 13th stage, cause it's a stage which can render people into an emotionless devil which only know how to kill."
"11th stage is called the Demon way."
"12th stage is called the Emotionless way."
"13th stage is called the Devil way."
"Which was why little Yu…."
"No matter how much you desire strength…"
"No matter how much you desire greatness…"
"No matter how much you desire revenge…"
"Don't ever try to get a strength that abandons your true self!"
"Because without your true self…"
"Even if you're the strongest person in the world, even if you able to rule the world, even if you able to kill all of your enemies…"
"All that left on you was just an empty puppet, devoid of your soul…"

So, Yin family first matriarch is named Yin Yin.
Why?
Because the future generation of Yin family only know that her name is Yin and since they're Yin family, they refer their first matriarch as Yin Yin.
and 13th stage...
Never try to reach it in this universe!
