Time flies, the green bamboo in the alternation of the four seasons, interpreting its different style, the murmuring stream in the change of temperature, reflecting its different connotations.

I don't know when, among the mountains, a young man with a basket on his back, wearing a hat, and his forehead was covered with sweat. He walked and stopped, not knowing what to look for in the mountains, and even sometimes put the green grass in the mountains into his mouth, chewing slowly, as if to taste something famous, when the young man showed satisfaction, as if he would put the green grass into the back basket behind him, and continue to search.

The hurried years seem to be eternal, but they do not lose the changes, and the once ignorant young man's immature face is no longer there. And that drop of sweat has unconsciously poured a resolute fruit and matured in Su Chen's heart.

Knowing medicine, researching medicine, various traditional Chinese medicine pharmacology, and the way of mutual growth and restraint are all growing rapidly under the guidance of the pharmacopoeia and the old man Mu.

This year, Su Chen was twelve years old, and he was still reciting the scriptures as always, studying the complicated pharmacopoeia, and shuttling between the mountains and forests every day, but in his heart, the fire of cultivation that he had always wanted to cultivate and become a strong man had been quietly extinguished.

Years have passed, and the spiritual veins are still the same.

It's just that on the top of Cangshan, there is one more quiet young man who often stops and plays the flute and chess alone to relieve the boredom in his heart.

The sound of the flute fell temporarily, and the aftermath came, only to see Su Chen put down the bamboo flute in his hand, and his slightly closed eyes slowly opened, but the raised brows at this time made his expression a little more dazed.

"It's been nine years......", Su Chen sighed, looking at the vast mountains that connect with heaven and earth in the distance, he really wants to integrate himself into it, return to nature, forget everything in his mind, and swim in this empty world.

He's tired, that's right, a twelve-year-old boy at this moment, he's tired. He was tired, tired that he didn't even know where he came from or what kind of environment he was born in, as if he had been forgotten by heaven and earth. He was tired, tired of years of boring scripture life, morning and twilight, year after year. He was tired and full of hope to ignite the fire of cultivation, but because the spiritual veins were blocked, he could not condense the spiritual energy of heaven and earth, and finally extinguished the ending......

Is it really as the scriptures say, "Heaven will descend on the people, and they must first suffer their minds?"

Su Chen encouraged himself again and again to actively face everything unknown, but everything did not get better, and he was at a loss.

Therefore, on this mountain, the song of the bamboo flute full of ambition and the years of waste, the game of heaven and earth is the only one, the black and white game of the chessboard beings, echoes in the heaven and the earth, and is interpreted between the warp and weft of the chessboard, as if only in this way can he vent the boredom in his heart and forget the bitterness in his heart.

"Brother...... Brother ......"

Suddenly, a shout interrupted Su Chen, who was deep in thought.

Coming back to his senses, Su Chen smiled slightly, revealing a soft gaze, and said to himself, "This little naughty." ”

I saw a girl in white, who was running very fast from the stone steps of the ancient forest at this time, with a light posture, smart and immortal, a few jumps, and she had already come to Su Chen.

The girl made a grimace, looking eccentric, and her eyes flashed as if she could speak, like an elf in the mountains, untouched by the world.

"You little naughty, don't go to cultivate, and come to play again!" Su Chen said with a serious face.

“...... Yu Xuan has just finished cultivating, and she has made progress again!"

The little girl blinked her watery eyes, looking a little aggrieved.

However, as soon as she finished speaking, the little girl seemed to realize something again, and then lowered her head and played with her fingers, and exclaimed timidly:

"Brother......

Regarding Xiao Yuxuan, who often accompanies Su Chen, in the past few years, the little girl has not only grown a lot taller, but also has shown a bit of a charming posture on her immature face, and between a smile and a smile, she is like a little elf.

However, Xiao Yuxuan didn't know what to do with her brother, so she often thought of ways to make him happy. What made her most depressed was that every time she made progress in her cultivation and wanted to share the joy with her brother, she would think of what her brother couldn't cultivate, so she often deliberately avoided it. But with a big heart, she will accidentally mention it every time she is happy.

However, Su Chen didn't blame her, and often encouraged her to cultivate hard and not be greedy for fun.

Maybe Su Chen pinned his hopes on his sister.

Su Chen seemed to see Xiao Yuxuan's worry, so he touched her head and said with a smile:

"Silly girl, it's okay, my brother will definitely go on strongly, otherwise who will protect Yuxuan in the future!"

"Did you say?" Su Chen smiled and quietly looked at the girl in front of him, as if she would never grow up.

"Protection?"

Suddenly, Xiao Yuxuan's heart seemed to be touched fiercely, and as if she had grown up all of a sudden, she raised her head and looked at Su Chen seriously.

As if to make the heaviest promise in this life, he said seriously:

"Brother, when I grow up, I will protect you!"

In just a few words, it seems to express a thousand words and emotions in Xiao Yuxuan's heart, because her brother will never be substituted in her heart.

And this sudden bold remark lingered in Su Chen's ears for a long time, making it difficult to calm down in his heart.

At the top of Cangshan Mountain, Su Chen looked at his sister who would never grow up in his heart, and was silent for a long time.

Let the breeze pass through his body and blow his hair, as if it also woke up the fire of cultivation that had long been given up in his heart and had been sleeping for a long time.

However, after a blink of an eye, Xiao Yuxuan, who no longer looked serious, seemed to be a little uncomfortable with this sudden quietness, so she dragged Su Chen, who was standing quietly, and said softly:

"Brother, are you hungry!"

Su Chen paused, came back to his senses, scratched Xiao Yuxuan's nose with a smile, and said, "You little gluttonous cat." ”

After speaking, he ran down the mountain with a mysterious expression,

"Let me taste my brother's new spices!"

Perhaps this is a characteristic that belongs to children!

......

The night moon descends, reflecting in the pool, the branches and shadows are swaying, stirring the moon's thoughts. The sound of frogs and cicadas did not stop all night, and before I knew it, a new day landed next to the quiet bamboo house at the foot of this mountain as usual.

As soon as the sky cleared, a sound came, breaking the silence of the night.

"Wake up, my brother went up the mountain to collect medicine, you little lazy worm, hurry up and go to morning exercise, don't be lazy!"

"Oh! ”

At this time, Xiao Yuxuan rubbed her sleepy eyes, yawned, and replied as if she were in a daze.

As usual, Su Chen began to repeat the same rhythm of life again, waking up early, collecting medicine, and waking up his snooze sister.

Carrying the basket, taking the utensils, just two steps, as if uneasy to shout:

"Don't be lazy! See you at the top of the mountain in an hour!"

After finishing speaking, he breathed a sigh of relief and set off with peace of mind.

However, as soon as he walked out of the small bamboo gate, Su Chen frowned, and realized in his heart that something was strange.

"That's not right! Grandpa Mu wasn't in the house last night, why is it lit up now?"

Then he looked around, and found that there were a few more black stones in the courtyard, and a flag that seemed to be made of black cloth.

Because of the weak light, I couldn't see what it looked like.

However, Old Man Mu has always been mysterious, Su Chen thought about it, and then he was relieved. Turn around and continue walking towards the mountain.

However, just after Su Chen turned around, the black flag magically emitted a faint light. But in an instant, it was ordinary again, and there was nothing unusual about it.

......

In the dense forest, I suddenly heard a few sword sounds, and I saw that next to an ancient tree, Xiao Yuxuan, who had already gotten up early, was wielding a wooden sword, sometimes slow, sometimes fast, sometimes pointing the sword and rising, light as a swallow, sometimes the sword moved, and suddenly like thunder.

The whole set of sword tricks seems to be very proficient, obviously after countless times of practice and a lot of hardship.

And at this moment, Xiao Yuxuan did not look weak in front of Su Chen at all, but a heroic posture that could be taken care of alone.

"Receive"

With a long exhale, she withdrew her wooden sword, and Xiao Yuxuan sat under the tree and began to breathe and breathe. If you look closely, you will find that there is a trace of spiritual light wandering around her, and then it is slowly sucked into her body and merges into the spiritual veins.

But as the aura continued to merge, changes abruptly emerged.

An unbearable pain suddenly came from Xiao Yuxuan's body, and in an instant, it began to burn in the spiritual veins like a soul-devouring fire, as if it was about to burn out the spiritual veins that bound the spiritual energy.

"Have you reached your limit?"

The heart-breaking pain made Xiao Yuxuan curl up in a ball and keep rolling, and the heart-devouring pain that would make people unconscious at any time did not weaken in the slightest because of the passage of time, and there was a more violent momentum, constantly destroying Xiao Yuxuan's spiritual veins.

"What should I do, what should I do...... Brother, do you know? Yu Xuan is really entangled! She never slacks off every day, she cultivates hard, and wants to become stronger to protect her brother, but Yu Xuan doesn't want to be different from her brother, Yu Xuan is so helpless......" Xiao Yuxuan said intermittently with a crying voice.

Who would have thought that this little girl who usually looks naughty and cute has such concerns, which makes people feel distressed.

Gradually, Xiao Yuxuan's consciousness began to become weak, and she was in a coma.

At this time, a figure appeared out of thin air, and in an instant, Xiao Yuxuan, who was already unconscious, was brought to the bamboo house.

The person who came was the mysterious old man wood, who was hunched over his waist at this time, his eyes were cloudy, looking at Xiao Yuxuan who was unconscious, but he was relieved and uncomfortable.

"Silly boy, you are grandpa's hope! The spiritual energy in the spiritual veins has been saturated for many days, but you have deliberately suppressed it, and you have not broken through for a long time and crossed the realm of spiritual induction.

"Grandpa knows, you don't want to make your brother Xiaochen sad and let him be different from you, but if you can suppress it for a while, can you suppress it for a lifetime!"

"Everyone has their own way forward, so why bother with it and not want to face it!"

"And if you don't break through, the spiritual veins will definitely be damaged, affecting your whole life!"

After speaking, the decadence in Old Man Mu's eyes disappeared instantly, and he saw a flash of light, and said decisively: "Today, grandpa will help you!"

As soon as the words fell, the originally rickety old man seemed to have retreated from his old posture in an instant, standing proudly, and a majestic figure suddenly appeared.

A deep drink!

A majestic spirit element actually gushed out from the old man's body, and then his sword and fingers stood together, gathering the spirit yuan at his fingertips, and turning the Danxing into a white state, pointing to the black flag that had stood in the courtyard early.

Suddenly, the golden light flashed, and I saw that the black flag suddenly receded from the ordinary state, suddenly became larger, and the golden light was overwhelming, and then, it rose into the air, as if with the momentum of swallowing the sky, and suddenly rushed into the sky, kept rolling, and the vision came.

And on the earth, Mu Lao didn't stop for a moment, only to see his feet on the Xinghe, stepping on Gangdou, connecting the five-sided black blocks in the courtyard that surrounded Xiao Yuxuan with strange steps.

As Mu Lao's steps flickered, around Xiao Yuxuan, who was in the center of the black block, a scorching breath followed, and in an instant, he saw that raging flames were gushing out of the black block in the five directions, rising to the sky, and it was extremely hot.

However, the surrounding environment is bizarre and unaffected by the flames, as if it is shrouded in a strange space, alternating fluctuations, and even illusory.

The raging flames were even rarer, and there were no crimson flames, but they were black, as if they were terrifying fires from hell. Immediately afterwards, I saw that based on the black blocks of the five directions, a black furnace came out, and Xiao Yuxuan was included in it.

Around the black furnace, a desolate aura suddenly permeated, as if it was examining the surrounding world and was about to swallow it at any time.

"Rumble"

Above the nine heavens, there was a sudden shock, and I saw countless thunderclouds gathering, which made this piece of heaven and earth suddenly fall into darkness, and the space that surrounded the black flag, at this moment, was as dark as abyss, and there were countless golden thunderbolts that kept rolling, as if one of them could raze this mountain and river to the ground.

Seeing the situation, Mu Lao did not hesitate at all, and burst up, as if he had turned into a spark, rushing straight up, submerging into the rolling thunder sea, and he was not afraid of the world-destroying thunder.

In the thunder sea, Mu Lao stood in the middle, he did not pause at all, accompanied by his hands in the void with strange lines, there were bursts of difficult ancient scriptures floating out of his mouth, the scriptures seemed to be substantial, the naked eye could be distinguished, the golden light was shining, flashing in the thunder sea.

Then, many extremely obscure scriptures began to pour towards the black flag in the thunder sea, and after a while, all the surging scriptures were sucked into it by the black flag, and a looming dragon-shaped pattern appeared on the black flag, emitting a little golden light.

Suddenly, the space around the black flag began to shake violently, becoming distorted, and exploded with a bang.

"Roar!"

I only heard a dragon roar, and it came from the void, and the pressure came, and the whole world shook.

"Old fellow ......" saw a huge dragon head, which suddenly came from the void and appeared behind Mu Lao, spitting out words.

"Haven't you given up yet?", the dragon whispered, looking at the black furnace on the ground.

It's just that Mu Lao stood quietly in the void, as if he hadn't heard it, and was silent.

"Since you insist on this, the old dragon will help you once!"

Immediately, the huge dragon head stopped speaking, and with the sound of bursting dragon groans, a drop of silver blood brewed out of the dragon's mouth, emitting heart-palpitating fluctuations.

In an instant, silver blood beads slowly came out of the dragon's mouth, submerged into the Thunder Sea, and with the power of the holy dragon, above the nine heavens, an unprecedented apocalyptic vision appeared.

"Thunder Sea Dragon!"

"Roar!" the dragon groaned.

Suddenly

The two powerful spirit elements fused from the Nine Heavens, turning into a terrifying thunder dragon, cutting through the air and roaring, more like the posture of gods and demons, carrying thousands of thunderclouds, without the slightest pause, and descending strongly.

On the earth, the desolate ancient oven seemed to feel a huge pressure, and it suddenly became larger, taking out an even more ancient aura, as if it wanted to swallow all the Nine Heavens Thunder Dragon into it.

"Boom"

In the blink of an eye, an earth-shattering bang suddenly echoed in the strange space surrounding the black furnace, and countless terrifying cracks began to spread, as if they were about to disintegrate the entire space!

And at the moment when the thunder dragon sank into the black furnace, an unyielding will suddenly appeared from the furnace, and black scriptures rose from the furnace wall one after another, endlessly, endlessly, one after another, the divine voice was long, and it seemed to be an extremely ancient scripture. As soon as these scripture formulas appeared, they turned into a cloud of black energy light shields around Xiao Yuxuan, isolating the terrifying thunder dragon.

And the black flame in the furnace did not have the slightest fear, and in an instant, it strongly refined and sucked into the terrifying thunder dragon in the furnace, and finally under the refining of the ancient black flame, the thunder dragon seemed to give up resistance, and finally fused with the black scriptures, turned into several silver beams, and slowly entered Xiao Yuxuan's body, with the effect of recreation.

I saw that in Xiao Yuxuan's body, the spiritual vein, which was originally difficult to repair once damaged, at this time, there was a sign of restoration, and under careful inspection, there was a little bit of silver flashing on the spiritual vein, giving people a texture like fairy gold.

Strange to say, the spiritual vein is the foundation of all things cultivation, the cornerstone, and the beginning of the avenue.

And with the passage of time, the silver energy magically repaired the spiritual veins intact, subverting common sense. And that majestic energy is still as much as fifty percent at this time.

But at this time, a full twelve spiritual veins appeared in Xiao Yuxuan's body, and they all appeared extremely spacious, and there was a feeling of full toughness, as if they would never be easily damaged again. And if an outsider sees it at this time, it must not be believed, because the realm of spirit attraction has twelve spiritual veins, which have transcended the cognition of sentient beings.

The legend of the twelve veins of the Spiritual Extreme Realm, only in those extremely ancient inheritances, will be recorded, perfect, that will be the darling of heaven and earth, if it grows, it will definitely be phoenix for nine days.

Once again, the aura is saturated!

Suddenly, the silver energy that was running in Xiao Yuxuan's body changed direction and rushed towards her Dantian Spirit Mansion, and in an instant, it broke through the sea and let out bursts of roar.

The sea of spirits is now!

At this time, Xiao Yuxuan can be regarded as having truly stepped into the threshold of cultivation, and the difference between immortals and mortals was born.

The newly opened spiritual sea, like a vicious wolf that has been hungry for an unknown amount of time, began to devour the silver energy frantically at this moment, and with the gathering of silver energy, the spiritual sea in Xiao Yuxuan's body began to expand rapidly.

Double, double, five......

With no signs of stopping, the silver energy eventually ran out as time passed.

At this time, the spiritual sea expanded a full tenfold, reaching the extreme that Xiao Yuxuan's body could withstand at this time.

When all the energy dissipated, the vision that appeared in this heaven and earth disappeared as if it had never happened. It's just that there is still a black flame around Xiao Yuxuan's body, which makes the surrounding space a little distorted, as if recording the shock just now, and it can't be calm for a long time.

The phoenix is born from nirvana.

When all this was completed, the huge dragon head didn't seem to have the intention of staying, but it glanced at Su Chen, who was sluggish on the top of the mountain in the distance, with some confusion, as if he was a little puzzled, but he didn't speak, and quietly disappeared into this world.

When the first rays of the morning sun appeared, Mu Lao fell with the light, and with a wave of his robe, he saw the black blocks in the courtyard disappear out of thin air and disappeared.

Looking at Xiao Yuxuan, who was lying on the ground, surrounded by flames, and did not react at all, Old Man Mu didn't seem to be worried at all, and then stretched out his finger and probed, and found that Xiao Yuxuan's body was full of spiritual sea, and his blood was vigorous, so he breathed a sigh of relief. Then he slowly said to himself:

"It's time to leave. ”

But as if he had thought of something worrying, Old Man Mu's brows were deeply raised, and his face was sad.

Regarding Xiao Su Chen, who has been with him for nine years and is like a child, it is extremely difficult for Old Man Mu to choose, and he has also thought about whether to take him away, away from the mortal dust, and go to the cultivation world that all beings yearn for. But all living beings know the brilliance in it, but they have never imagined the cruelty in it, not to mention that Su Chen can't cultivate, he is an ordinary person, rather than being in such a cruel environment where strength is respected, it is better to live a life in this mortal dust.

At this time, Su Chen, who was on the top of the mountain, was in a turbulent mood in his heart, and the terrifying vision that appeared in this world just now, and the feeling that he seemed to be stared at by some terrifying existence in an instant, and he would be destroyed at any time, told him that something big must have happened here.

It's just that Xiao Suchen, who was in shock, didn't know that in the past hour, something happened that changed the trajectory of his life from then on.
