Qin Yu sat in place, his mind roaring, recalling the words of an ancient book in the library building on the highest floor of the Tianqi Sect, and his heart set off a storm.

"At the beginning of the mixed yuan, there were ancestors who pursued the ultimate power, and after the evolution of the ages, they created the trick of "hundred refinements", what is a hundred refinements?"

"A thousand hammers in the body, a hundred tempers its heart. ”

"What is a thousand hammers? the dirt of the scattered body, the essence of the condensed body. ”

"What is the tempering of its heart? Ups and downs, scattered and returned, is really to sharpen its heart, firm its perseverance. ”

"This trick is practiced in the body, cultivation and refinement, accumulation and thin hair, late blooming, boiling thousands of hammers in the body, refining its heart, in order to win!"

"In the early years, someone relied on this trick to refine an invincible body, an immortal heart, and then was trapped in the prison of the years by the people, so far, the hundred refinements are extinct, and this person is called the first ruthless person in the beginning!"

.........

"Ups and downs, scattering and coming back, accumulating thick and thin... Is it really a hundred refinements?how is it possible!" Qin Yu was shocked, and he even had an impulse to ask Qin Zhan, what was the spiritual secret of his cultivation......

If it was really a "hundred refinements", then it was impossible to imagine how far Qin Zhan would step into it in the future!

"Whew!" Qin Yu took a deep breath, forcibly suppressed the shock in his heart, carefully recalled every word Qin Zhan said, and became more and more suspicious in his heart, even if it was not a "hundred refinements", it must be almost the same, after his cultivation regressed, his cultivation strength would become stronger every time he refined, and with the opening up of the sea of suffering, it could be concluded that the spiritual technique he cultivated was extraordinary.

Moreover, the sea of suffering is not open to everyone.

Only when the physical body has reached the point of extreme strength can it have a chance to be opened, and once it is opened, the path of cultivation will be extremely difficult.

The reason why the sea of bitterness at the center of the eyebrows is called the sea of bitterness is really because the cultivation is difficult, and the hardships encountered are incalculable, but the cultivation is difficult, and the rewards are extremely rich.

As the saying goes, the sea of suffering is endless and boundless.

In ancient times, it was not uncommon for people to open up the bitter sea, but now, Qin Yu concluded through the Qin family's library that almost no one would open up the bitter sea.

Wait a minute!!

Qin Yu suddenly remembered that his father Qin Zhan said that his mother had left something in his body, but Qin Yu had carefully looked at his body and didn't notice anything, could it be that thing was in the sea of suffering?

No way!!

When pigs fly!

If you are placed in the sea of suffering, you will not be able to open the sea of suffering for the rest of your life with the qualifications of your predecessor.

Unless!

At the age of sixteen, the sea of bitterness will open up on its own, but this... It's even more appalling!

Even if Qin Yu had read all the Tianqi Sect Library Pavilion, he had never heard of anyone whose sea of suffering would open up on its own.

Thinking of this, Qin Yu felt that the mother in his memory had become extremely mysterious, and his father must know something about his mother's origin, but he didn't want to reveal it.

Mother, what is the origin?

Qin Yu fell into deep thought, but carefully recalling the memories of his predecessor, Qin Yu didn't get the slightest clue, so he had to put this thought down, coupled with the current enemy, Qin Yu needed to improve his cultivation to the Gang Qi realm as much as possible in five months.

Originally, Qin Yu mostly just guessed that Cui Fu had a relationship with Qinglian Cui's family, and it was confirmed from his father Qin Zhan, which made Qin Yu vaguely worried, during this time, Cui Fu was afraid that Cui Shuo would do everything possible to improve Cui Shuo's strength, and even did not hesitate to use other external forces, such as pills!

"Five and a half months is not a long time, but the only thing I can rely on is the Six Transformations of the Mad Demon, although I know many combat skills, but I can't show its strength yet. ”

"Moreover, since the first transformation of the mad demon is to burn qi and blood, then, during this period of time, I need to improve my cultivation and improve my own qi and blood, if I can learn ten thousand times, it would be great. ”

Although the Ten Thousand Heavy Battle Technique was created by Qin Yu, this does not mean that he will use it, and it will take a long time to sharpen!

After a little silence, Qin Yu made a decision in his heart, so he got up to leave, but found Xue'er and the thirteenth princess Long Yu standing not far away, while Xiao Tao and Xiao Hua were squatting in the distance and whispering something, and when they noticed Qin Yu walking out, the two raised their heads and looked at Qin Yu in a complicated way.

"Brother..."Qin Xue shouted, trotted over, stood in front of Qin Yu, raised his head, looked at Qin Yu with red eyes, and said nervously: "Brother... Are you really going to fight Cui Shuo in five months?"

Qin Yu glanced at Long Yu, wiped away the tears on Qin Xue's cheeks in distress, and said softly: "Didn't you say it? Do you want your brother to protect you? If you can't even win Cui Shuo, what will your brother do to protect you?"

"But... Xue'er doesn't need her brother's protection, Xue'er just wants her brother to be safe, brother, you have to promise Xue'er that she must win against Cui Shuo, okay?" Qin Xue, who was a head shorter than Qin Yu, hugged Qin Yu tightly and whispered.

Qin Yu stroked Qin Xue's hair and smiled, "Of course, my brother is actually very powerful." Saying that, Qin Yu looked at Xiao Tao not far away and said, "Xiao Tao, bring pen and ink." ”

Xiao Tao hasn't come back to her senses, Xiaohua turned around and trotted away to get pen and ink, now Xiaohua is very fond of Qin Yu's admiration for the five bodies, and she is also in awe of Qin Yu, at the beginning, Qin Yu and Cui Shuo fought, although Xiaohua was injured, but she was not unconscious, she has been watching secretly, I have to say, Qin Yu's fierceness all hit Xiaohua's heart.

"Thirteenth princess, thank you for these two times. Qin Yu glanced at Long Yu and said movingly, regardless of whether Long Yu approached with a purpose or not, but Qin Yu was moved by the help twice.

Long Yuqiao's face was slightly red, and she pretended to be calm and said: "Brother Qin is polite, I am friends with Xiaoxue, and I can't get used to the Cui family's flying and domineering." In the past, Long Yu and Qin Yu had little contact, but the battle between Qin Yu and Cui Shuo made Long Yu's heart pound, and there were vague signs of a girl's spring, plus Lenovo heard how Qin Yu peeked at himself, which made Long Yu a little shy.

Long Yu is two years older than Qin Yu, but now he unknowingly calls Qin Yu his eldest brother, which Long Yu himself didn't notice.

Long Yu's expression, Qin Yu took in the bottom of his eyes, and after a moment of silence, Qin Yu said, "The roots of the thirteenth princess should be very mediocre, right?"

The originally ruddy cheeks turned pale in an instant, and Bei Yan bit his red lips tightly, not daring to look directly at Qin Yu.

"I don't know what kind of spiritual trick the thirteenth princess cultivates. Qin Yu asked.

"Heavenly Dragon Jue. Long Yu said in a low voice, for some reason, in the face of Qin Yu's deep gaze at this time, Long Yu instinctively felt inferiority in her heart, she forgot that she was a princess on top, and Qin Yu was just the son of a businessman.

"With the identity of a princess, the treasures of heaven and earth should be indispensable, why does Xiu Wei stay in the martial realm double?" Qin Yu didn't seem to notice Long Yu's depressed mood and continued to ask.

"The Emperor's family is not as glamorous as you think, and mediocre roots mean that you can't get cultivation resources. Long Yu bit her red lips tightly, her light eyes were full of unwillingness, this time, she actually raised her head and looked at Qin Yu.

Qin Yu was not surprised by what Long Yu said, the family affection of the emperor's family was even weaker, and this martial country was just a puppet, as a princess, Long Yu was afraid that it was only bright on the surface, nothing more.

"Mediocre roots do mean that they will be unknown for the rest of their lives, and perhaps, it is best to let go of it long ago. Qin Yu stared at Long Yu's eyes and said word by word.

Long Yu's face turned even paler, she was short of breath, and there was no previous unwillingness in her eyes, instead of Li Mang, to be precise, ambition and longing, she met Qin Yu's gaze, tears flashed in her eyes, and she said in a low voice: "Is it true that if the root bone is bad, it is destined to be mediocre for a lifetime? I don't believe that I Long Yu will be mediocre for the rest of his life, one day, I will break the shackles and let everyone know that mediocrity does not mean anything!!"

Long Yu's words were almost shouted out, as a princess, she enjoyed the reverence of countless people, but she had a heart that yearned for cultivation, and she dreamed that one day she would be able to reach the peak of the place she went and become a real human being!!

Qin Yu glanced at Long Yu in a complicated manner, felt the strong desire and unwillingness burning in Long Yu's eyes, and said indifferently: "I hope you will always remember what you said today." ”

At this time, Xiaohua came in a hurry with pen and ink, Xiaotao came in a hurry with the table on her back, and Qin Yu directly took the pen, dipped it in ink, and wrote quickly on rice paper.

A moment later, when the four of them didn't have time to see what Qin Yu wrote, Qin Yu finished writing, took one of the rice papers and handed it to Xiao Tao and Xiao Hua, and said, "Behind the cooking, destroy it!", as he spoke, the other one was handed to Long Yu, who was clenched with his fists and his eyes blurred with tears.

"You can take a look here, if you can cultivate, you can practice the spiritual recipe on the paper, Xue'er, follow me to my father's place. Qin Yu said, Qin Xuehu nodded suspiciously.

The two of them left the small courtyard and walked on the avenue, and after Qin Yu made sure that there was no one around, he said in a thin voice: "Write down this mantra, don't do it, this mantra can't be revealed to anyone!", as he spoke, Qin Yu recited a mantra in Qin Xue's ear, this mantra is the Heavenly Dao Immortal Formula! Qin Yu let Qin Xue cultivate first, and will help her improve it in the future.

Although Qin Xue was suspicious, she memorized the mantra with her heart.

After making sure that Qin Xue was on his back, Qin Yu took out another envelope and said, "You take this envelope and go to the Vientiane Dan Shop later, just say that you are looking for Zixun'er Zi Dan Master, and by the way, you will say something for me, just say, "Someone asked you to go down as an example"! Okay, remember to go and cultivate what you just memorized, and besides, I will leave the Qin Mansion for a few months, and then you can tell your father, okay?"

"Brother... Where are you going?" Qin Xue said nervously and worriedly.

"Of course, it's to improve your strength, okay, you go to your father's place, you take this spirit stone, if anything happens to the Qin family, put this spirit stone in the groove under the Danding in my room, and you can leave the Qin family less during this time, do you hear?"

Meanwhile.

When Long Yu stared at the few big characters on the paper in a daze, his delicate body trembled violently, his eyes condensed, and the tears in his eyes couldn't stop dripping like beads with broken threads, but his delicate face showed a look of ecstasy.
