It was a dark night with a blurred moonlight, and there was a valley about dozens of kilometers away from Gransdy City, this valley was hidden in the mountains surrounded by mountains, and on three sides were towering and steep peaks, and the entrance was full of many poisonous vines and plants, which seemed very hidden, this place was found by Sun Xiaofei for several days, and it was used to cross the place where the golden pill was condensed.

According to the arrangement of the academy teacher, Sun Xiaofei went to participate in the selection competition to enter the Holy Dragon Academy, and his cultivation was naturally very easy to obtain, and the quota recommended by the Principality Academy was selected to enter the Imperial Holy Dragon Academy for further study. When many apprentices had only reached the level of a sword master, Sun Xiaofei's cultivation in the later stage of foundation building was equivalent to the ninth level of the Great Sword Master, but when he participated in the selection, he did not show all his strength, and when it was not necessary, Sun Xiaofei did not want most people to understand his true strength.

Rao was like this, and the teachers of the academy who were present to supervise him all looked at him differently, calling him a cultivator of the Principality of Fiji for hundreds of years.

After a long period of accumulation, Sun Xiaofei's Shocking Rainbow Sword Technique has been cultivated to the third layer, and the Tongtian Treasure Book has also been cultivated to the fifth layer realm, and his cultivation has reached the bottleneck of breakthrough, and now it is time to cross the tribulation. This is also the reason why his soul is extremely strong, he has the advantage of innate true yuan power, and he has the cultivation experience of his previous life, so it is naturally impossible for others to enter the knot stage in just ten years. As long as Sun Xiaofei can survive this first cultivation tribulation, he will be reborn and enter the early stage of the knot. The fire of Jindan will also be formed in the body, which can be dissolved into the refining material of Wujin Iron to refine his first flying sword magic weapon.

Although Sun Xiaofei had already experienced the transition tribulation in his previous life, but at this time, Sun Xiaofei still felt a little uneasy in his heart, he didn't fully understand the world he was in, so he didn't dare to have a relaxed mentality. In order to ensure that he survived the tribulation safely, Sun Xiaofei made some preparations for guarantees, such as defending the magic array, restoring spiritual power, etc., to increase the conditions for the success of the tribulation.

Sun Xiaofei calmly guarded the spiritual platform, and before the Heavenly Tribulation came, he adjusted his state in order to cope with his first cultivation tribulation. The night is thick, everything is quiet, and there is an oppressive storm in the calm, which is about to erupt.

Suddenly, a rumbling sound suddenly sounded, and the aura within a radius of dozens of miles began to riot, and the whirring wind suddenly appeared out of thin air, and countless clouds in the sky gathered here in the valley, and a huge spiritual power fluctuation was brewing between heaven and earth. The demonic beasts with a little wisdom in this mountain range, feeling the changes in this vision of heaven and earth, all kinds of birds and beasts under the coercion shrouded range immediately roared, and then quickly scattered and fled this area.

The majesty of heaven descends, and it is vast and unpredictable. Countless clouds formed a huge vortex above Sun Xiaofei's head, exuding astonishing aura fluctuations. With Sun Xiaofei as the center, electric sparks flashed in the clouds, and suddenly a thunderclap roared, and in an instant, lightning and thunder roared, and violent storms and rain poured down, raging all over this valley.

Sun Xiaofei stood up and looked up at this scene, a faint white light curtain appeared on his body, and as soon as all the storms approached his body, they were blocked by this layer of protective light curtain. After a while, the Heavenly Tribulation above condensed enough energy, and with a snort, a cyan electric light flashed down, aiming at Sun Xiaofei below. Sun Xiaofei's hand quickly transformed into a heart-protecting handprint, and the light curtain on his body grew a little stronger, becoming thicker, and calmly accepting the attack of this heavenly tribulation. The electric light flashed and fell on the light curtain, and the light curtain only resisted for a moment, and then turned into a little spot of light and dissipated. Sun Xiaofei didn't expect the first heavenly tribulation to be so powerful, fortunately he was prepared, his hands were crossed, and he used a kind of defense to resist, snorting, the electric light touched his palm, and then it sank into his body along the arm, and suddenly, Sun Xiaofei was covered in green lightning, his sideburns stood upside down, and he immediately operated the innate true yuan force in his body, devouring and expelling a thunderbolt force that invaded his body.

The Tribulation hovered above his head and gave him a chance to breathe. Sun Xiaofei just had time to dissolve the power of thunder and lightning that invaded his body, but the paralysis caused by the thunder and lightning blasting into his body just now had not subsided, and a thicker thunderbolt fell from the sky and hit Sun Xiaofei, who was temporarily unable to move.

Sun Xiaofei tried hard to urge the True Yuan Force to resist the thunderstorm, and the organs and meridians in his body were destroyed by the electricity of the thunderstorm, tearing out wounds one after another, and the lightning was black and mushy everywhere, and the sharp pain in the heart was unbearable. True cultivators are all extremely resolute in their minds, and Sun Xiaofei is working hard to repair his body, while using all his true yuan power to resolve the damage of the power of thunder and lightning.

Just as he had finished dissolving the power of the Tribulation Thunder, another Heavenly Tribulation energy in the sky had also been condensed, ready to give him the last thunder blow. The coercion shrouded in heaven and earth increased a few points, making Sun Xiaofei's whole body tremble, and he could vaguely hear some light sounds from the bones in his body, under the pressure of such a huge heavenly tribulation, Sun Xiaofei landed on one knee, his breathing was rapid like a bellows pulling, and his whole body was in pain. He glanced up at the calamity clouds above and knew that this last heavenly tribulation was not trivial, the time was very urgent, and he had to take all the necessary preparations to resist it.

Sun Xiaofei quickly took out the pill of the Returning Qi Pill Guyuan, and swallowed it into his stomach without hesitation, and the pill turned into a stream of pure spiritual power, replenishing the True Yuan power consumed in his body. These pills were prepared by him before the catastrophe, in order to cope with the current situation in front of him. Sun Xiaofei formed a formation mark with both hands, and several rays of spiritual light burst out from his hands, opening a defensive magic array Xuanyuan Array.

Thundered...... The surrounding clouds converged in the middle, and a reddish lightning bolt fell vertically, as fast as if tearing through the sky. Sun Xiaofei was taken aback when he saw it, and his pupils couldn't help but shrink, the Red Refining Tribulation that only existed in the Six Tribulations actually appeared at this time. At that moment, he didn't dare to delay for half a minute, took out a green steel sword in his hand, and used the Rainbow Sword Technique to defend the sword and greeted him.

Rumble!......

The entire valley flashed with lightning, a spiritual light spread to the surroundings, the ground caved down, and a pit more than a foot deep appeared in the valley, Sun Xiaofei lay on his back in the pit, the green steel sword shattered and only one sword hilt remained, and some spiritual energy that had not yet dissipated floated around him. A layer of red light enveloped Sun Xiaofei's whole body, making his breath extremely weak, fluctuating like a gossamer, and it seemed that it would disappear at any time.

The Tribulation came and went quickly, and when all the energy was consumed, it began to dissipate gradually, and it disappeared completely in less than a few breaths. The valley was silent, and there was no sound other than the rain and wind, which had begun to wane. Heaven and earth suddenly returned to normal, only the sparse rain washed away the ravaged valley, and the motionless body in the earth pit, and the valley was speechless to witness the scene that had just happened.

Sun Xiaofei's movements across the catastrophe were not small, but there was such a violent thunderstorm raging in this area, covering up these movements, and the scope of the catastrophe was relatively small, and it did not attract anyone's attention. Who else braved the storm in the middle of the night to come to this remote valley?

With the passage of time, the red light that shrouded Sun Xiaofei's body gradually faded, and then submerged into Sun Xiaofei's body. These red lights were originally the purest spiritual power of the Red Refining Tribulation, which could temper the body and soul of the Tribulator at the same time, and once they couldn't resist it, they would turn into demons and become a walking corpse-like being. The probability of this kind of Red Refining Tribulation appearing is very low, usually only appearing in the Sixty-Nine Heavenly Tribulation, and it is one of the Heavenly Tribulations that many cultivators are very afraid of. I don't know why, today it will appear in Sun Xiaofei's crossing.

After absorbing the pure spiritual power of the Heavenly Tribulation, Sun Xiaofei's body was repaired at a terrifying speed, and all the parts that were damaged were squirming sharply, and the speed visible to the naked eye was repairing as before. The residual spiritual power was still refining his body, making his body gradually strengthen, and countless spiritual power in the dantian was surging, pouring into the cyclone, making the originally almost exhausted dantian suddenly filled with endless spiritual energy.

Every time you cultivate the true tribulation, if you can survive it smoothly, you will usher in a further transformation process of the body. This process is to continuously refine the body, so that the body of the cultivator becomes more powerful in the heavenly tribulation after heavenly tribulation, and moves towards the next realm, until it flies to become an immortal. If you can't resist, you will be wiped out and turned into dust.

The aura in Sun Xiaofei's dantian gathered more and more, the quantitative change caused the qualitative change, and the aura began to transform from a dense mist to a liquid, and then solidified into a crystal from the liquid, and countless small aura crystals rotated rapidly around the center, and then gathered tightly to the center, layer upon layer tightly together, like a magnet inseparable. Boom...!The dazzling light suddenly appeared in the dantian, and then the light formed a small golden ball, the realm of the first knot of the golden pill, which is the sign that the cultivator has entered the dan stage from the foundation building period.

Jin Dan kept rotating, and the rotating power spread to the surroundings, and all the crystals turned by the surrounding spiritual energy were shattered into atomized spiritual energy, and then absorbed by the Jin Dan, adding a trace of spiritual power to the volume of the Jin Dan.

Sun Xiaofei didn't know how to return home, he rested at home for two days, consolidating the current realm, now the true yuan power in his body has increased a lot, and the power is even stronger than before, as long as his mind moves, there will be dozens of times stronger spiritual power than the original gushing out.

At night, the lights illuminated the room, Sun Xiaofei took out the refined black gold stone, and began to cast the long-awaited Sky Sword, because the Rainbow Sword Technique is a strong and powerful way of cultivation, not only to ask for good materials for the flying sword, but also to have a formation to complement it, so that the magic weapon can have the effect of tearing space. Sun Xiaofei opened his mouth and spit out a Dan fire, the Dan fire wrapped in the black gold iron and burned violently, the temperature of the Jin Dan fire was terrifying, and with the support of the true yuan power provided by the Jin Dan in the body, the process of refining the black gold iron was quite smooth, and the first piece of black gold iron was refined into a black liquid.

Sun Xiaofei sped up his speed and refined the other Wujin Iron together, and the cultivation realm was high, and the refining speed was much faster. These refined black liquids formed a sword according to Sun Xiaofei's intentions, and the seals in Sun Xiaofei's hands were punched out one after another, and the inscription formation was completed in one go, and if there was a slight mistake, not only could it not be refined, but these materials could also be scrapped. There are still some steps before the flying sword is formed, and the magic weapon enlightens!

Sun Xiaofei popped out a drop of sperm blood and shot onto the sword body suspended in front of him, the flying sword calmed down after a shock, and then the sword body turned into a dark gold, flashing with a compelling cold light, this sword was the Sky Sword refined by Sun Xiaofei. Sun Xiaofei took the flying sword into his hand with his fingers and carefully inspected it, the flying sword magic weapon of the intermediate magic weapon level. Sun Xiaofei nodded with satisfaction, and finally breathed a sigh of relief in his heart, and hurriedly played a magic decision to make the flying sword smaller and put it into his body.

At this time, a wave of exhaustion hit, and there was no time to test the power of the flying sword, Sun Xiaofei relaxed his spirit, and lay on the bed with his head down and slowly fell asleep.

The next morning, Sun Xiaofei went to an academy in the city in good spirits. This is the only academy in the city, the establishment year can be traced back to the history of the construction of Gransdy City, the academy has more than a dozen teachers, respectively teaching various knowledge and skills of the Via continent, Sun Xiaofei is here to learn the common language and combat skills of the continent. Of course, how can the swordsmanship of this continent be comparable to the master's stunt that Sun Xiaofei has learned.

In order to cope with his parents' expectations of him, and not wanting to expose the secrets of his cultivators, Sun Xiaofei had no choice but to do what they arranged. Sun Xiaofei was a well-known cultivation wizard in the academy, and those basic knowledge courses in the academy were not difficult for him at all, so as soon as the school time came, Sun Xiaofei immediately left the academy and returned home.

In the backyard, Sun Xiaofei gathered momentum and began to practice the martial arts of the master. Sun Xiaofei understands that only by diligent and pendeficence can he have enough strength to walk his own way, and strength is the basis for him to walk this world in the future. Routine practice every day is an essential thing for him to do.
