In a stone chamber of tens of zhang in size, there is nothing here, except for a stone platform more than half a zhang high in the center, and on this stone platform, there is a ball of light that emits heavy white light.

An extremely astonishing fluctuation of spiritual yuan and medicinal fragrance permeated the entire stone room, causing patches of mist to appear in the stone room, and the white expanse covered people's vision.

There are nine stone doors in this stone room, and eight of the nine stone doors are closed, not opened, only one stone door is opened, and Feng Xuan is standing in front of this stone door, his eyes wide open at the ball of light on the stone platform in the center of the stone room.

"Nine Yuan Dan!"

Feng Xuan stared at the ball of light with rapid breathing, his eyes flashing with an extremely hot light.

The alchemist, refined by the alchemist, has a wide variety, has great value, the alchemist is very rare in the Xuanling world, it is difficult to appear one among ten thousand, because to become an alchemist, you must have a talent, and you can't become an alchemist without talent, which leads to the alchemist is extremely rare, and the status of their group of people in the Xuanling world is extremely high, and they are respected by many monks.

There are all kinds of pills, and their medicinal properties are different, very different, and even some pills are several times stronger than the spirit yuan contained in some ordinary heaven and earth elixirs.

Jiuyuan Dan, which is made with the Nine Yuan Fruit as the core and refined with the cooperation of many kinds of heaven and earth spirit grass, has great use for the body of the Yuan Spirit, which can achieve the effect of refining and making the body of the Yuan Spirit more powerful and condensed.

During this period of time in the Sanyang Sect, Feng Xuan also read many books. He probably also had a corresponding understanding of some of the Xuanling World Realm, and he naturally knew about this Nine Yuan Pill, which was the best even among the many types of pills, and it was rare.

Feng Xuan suppressed the excitement in his body and tried to calm himself down, he glanced at the situation around him, and when he found that there was no danger, he slowly walked to the center of the stone chamber and reached out towards the light cluster on the stone platform.

"Whew!"

As soon as Feng Xuan's hand reached into the light cluster, a sharp sound of breaking the sky sounded from the mist in an instant. Immediately after, a black feather arrow shot at the back of Feng Xuan's head as fast as lightning.

Feel the shrill sound behind you. Feng Xuan seemed to have noticed it, and his face remained unchanged and he quickly withdrew his right hand that had been stretched into the light cluster, clenched his fist with blue light and punched backwards with the black feather arrow that was coming.

"Bang!"

An extremely low voice sounded, and the blue light fist blasted the entire feather arrow into a large black point of light all the way. Scattered around.

Feng Xuan withdrew his fist and slowly turned his body. At a glance, I saw a young man in a black suit standing in front of an open stone door.

The young man was holding a large black bow in his hand. His hands were in a gesture of opening his bow, and it was obvious that the arrow had been fired by the young man.

"You are Feng Xuan?" the young man in the black power suit looked at the light cluster on the stone platform, and then his gaze stayed on Feng Xuan's body. Road.

"I am, what's the matter?" Feng Xuan asked with a cold look at the young man.

"I am the tenth son of one of the thirteen sons of the Night Heaven Palace, you killed my thirteenth brother, although I don't like him, and I don't have much blood relationship with him, but he is my thirteenth brother after all, since I met you here, I will kill you to avenge him." As the young man spoke, a black feather arrow condensed from his black bow, flashing with a sharp edge, pointing at Feng Xuan from afar.

Feng Xuan didn't speak, but there was already indifference in his eyes, and blue light gradually appeared on his hands.

Seeing Feng Xuan's appearance, an astonishing chill also appeared on the young man's face, and then he directly released the arrow string, and the black arrow condensed by the spirit yuan emitted a sharp whistling sound and shot towards Feng Xuan at great speed.

"Whew!"

Another shrill sound sounded, and the black arrow soon came to Feng Xuan.

"Don't do this kind of attack anymore. When Feng Xuan opened his mouth lightly, his blue right fist exploded the black arrow with a punch.

The young man in black didn't pay attention to Feng Xuan, he shot three arrows in a row, and then six more arrows, three arrows in front and six arrows behind, and they all headed towards Feng Xuan, blocking all his retreats.

"Arc Knife Trick!"

A low shout suddenly sounded in Feng Xuan's heart, and then the blue light in his right hand skyrocketed, and he slashed straight forward with one hand.

A huge blue blade suddenly appeared as Feng Xuan slashed straight down with one hand, and directly slashed at the nine arrows.

"Click!"

The nine black arrows all shattered in an instant, and the blue giant knife slashed at the black-clothed young man at an unabated speed.

The young man's figure flashed and quickly dodged this blow, and he shot eighteen arrows at Feng Xuan in a row in his dodge, and the power of each arrow was much stronger.

However, what made the young man's pupils shrink was that the blue giant knife suddenly appeared again, and collided with the eighteen arrows he shot in mid-air.

"Boom!"

The two collided, and a blast of wind swept out, dispersing all the fog in the stone chamber.

When everything was calm, the blue giant sword and the eighteen black arrows canceled each other out in the collision just now and dissipated.

"Sure enough, there are two hits, no wonder you can kill Night Thirteen, but it's a pity that you met me, and I'm much stronger than that waste. The black-clothed young man spat out these words coldly, and then a violent wind of powerful spirit yuan fluctuations suddenly erupted from his body.

This spirit element fluctuation is extremely strong, and under Feng Xuan's detection, it has reached the middle stage of the Yuan Spirit Realm, and it is also the peak of the middle stage, and it can break through to the late stage of the Yuan Spirit Realm at any time.

The three purple jade arrows were taken out by the black-clothed young man and placed on the black big bow, and a palpitating fluctuation came out of the three purple jade arrows in an instant, making people's skin involuntarily glow with a chill.

"Now, you can die!" the young man sneered, his hand had loosened, and the three purple jade arrows had left the string and shot forward.

"It is your ...... to be able to die under these three arrows" The black-clothed young man stopped abruptly before he finished speaking, his eyes stared wide ahead, the three purple jade arrows that had broken off from his body a foot away.

A splattered wisp of blood spurted all around, and the eyes of the black-clothed young man fell wide, and there was still disbelief in his eyes.

"You're too conceited. Feng Xuan's voice came from behind the young man, and he could be seen holding a cyan sword hilt in his hand, and there was a rapid whirlwind circling under the sword hilt, sending out a fluctuation that made the space faintly fluctuate, this sword hilt was the mysterious weapon that Feng Tian transported to Feng Xuan, the empty blade.

The three purple jade arrows were broken by this empty blade, and an extremely deep wound on the neck of the black-clothed young man was also placed by this empty blade, causing a fatal wound that made the young man die instantly.

Feng Xuan looked at the body of the black-clothed young man, he didn't go to get the black big bow, but picked up the three purple jade arrows that were broken on the ground, and then grabbed the Jiuyuan Dan in the light cluster on the stone platform in the center of the stone room, quickly pushed open a stone door, and left the stone room.
