On the second floor of Xuanling Pavilion, Kong Laosan sat opposite to Master Ku, and Yuan Zun stood quietly behind the Taoist, without saying a word.

"I really didn't expect such a thing to happen, the human race is already weak, and now the Wind and Thunder Ancestor, one of the three peak venerables, was actually attacked and killed by demons, alas, is it true that our human race is really exhausted?"

Master Ku said slowly, and his voice revealed one of infinite loneliness.

"How did the Wind Thunder Ancestor die?"

Although he had already guessed in his heart, Kong Laosan couldn't help but ask, as if he had pressed a boulder in his heart, and it was heavy.

"I don't know exactly how the old man is, it is said that he was attacked and killed by a demon venerable called the Weeping Heaven Venerable, since the disappearance of Chen Fusheng and Lingji, the situation of the human race has become more and more difficult, and now the three Venerables have gone to another one...... I'm afraid that those demon clans will take the opportunity to attack on a large scale and completely wipe out the human race from the land of Xiling!"

Master Ku shook his head, as if talking to himself, and there was obviously a bit of despair in his tone.

"Sure enough, it's him!"

Kong Laosan sighed slightly in his heart, and finally shook his head, seeing Master Ku like this, he couldn't help but open his mouth to persuade, "Master rest assured, the human race is favored by heaven, maybe one or two hundred years later, there will be another natural disaster!"

"Hehe, that's it, don't talk about this, those spiritual old men are ready, seniors come with me!"

With that, he got up and walked towards the backyard.

The entire Xuanling Pavilion covers an extremely wide area, about 100 acres in size, and about 300 underground caves have been built in the back hall, which is used for alchemy with a special formation to attract the fire power of the center of the earth. After a short time, the two of them came to one of the caves one after the other.

The cave in front of me is located more than 30 zhang underground, about the size of three houses, and the surrounding stone walls seem to be wrapped with a layer of cyan jade that isolates heat, and the dog is connected with many formation lines on it, and it gives people a cold and cold feeling.

Beneath the ground, a half-human-sized three-legged ancient tripod landed on it, and a swarthy hole stretched out below, as if it had been sealed by some kind of power, and it could not feel the slightest heat.

"Here it is. ”

At the same time as the voice fell, with a lap on his waist, countless various spiritual herbs and treasures were born out of thin air, spreading all over the ground, and at the same time, there were many wooden boxes and jade boxes and a large number of bottles and jars. Seeing this, Kong Laosan flipped it with one hand, and the Xuanbing jade box flew directly towards Master Ku, and landed firmly in the other party's hands.

"Hehe, I really didn't expect that the old man would be able to configure this rumored spiritual liquid with his own hands in his lifetime, but unfortunately, I'm afraid there is only this one chance!"

The old man said, stroked the jade box in his hand, and placed it in front of him with some reluctance, and at the same time, pinched the trick with both hands, and gently touched it towards the bottom of the fire tripod, and the originally dark hole suddenly bloomed with a strong red flame power, "It will take about ten days to prepare the spiritual liquid!"

At the same time as the voice fell, Master Ku's sleeve rolled, and one of the herbs with green leaves and white cores fell into the ding, and under the blazing heat, the herbs that originally exuded bursts of cold air gradually melted, and the wisps of white medicinal juice gathered into the size of a finger, coiling in the fire ding.

One after another, but in just three days, more than seventy drops of herbal spiritual liquid have been lingering in the fire ding, large and small, these spiritual liquids are of different sizes and colors, and they are constantly tempered at various temperatures under the shroud of divine thoughts, like a picture scroll, which makes people marvel.

Seeing this scene, Kong Laosan's eyes flashed with a hint of admiration, such an alchemy method, no wonder he was respected by countless cultivators as the number one alchemy master in Xuanyuan City.

Time passed slowly, the temperature in the fire tripod was getting higher and higher, and countless spiritual liquids were not stopped, at this moment, the bitter master seemed to have reached the limit, his face was pale, and his expression was sluggish, but he did not give up, and when the last spiritual material was refined, he finally fell on the Xuanbing jade box, and with a slight click, the jade box opened in response, and at the same time, a petal like a black crystal seemed to be summoned by some kind of power, slowly floating into the fire ding.

At this moment, a wisp of black flame condensed from the fire tripod, which was originally only a high temperature, constantly licking the petals of the Nine Turns Lotus, and at the same time, wisps of black qi continued to float out from the latter's body, like silk threads, towards the three hundred drops of various spiritual liquids in the fire tripod.

Five days later, above the fire tripod, the black halo flowed, like a substantial film, completely burying the entire fire tripod, until this moment, the bitter master breathed a long sigh of relief, and his extremely pale face barely smiled, "Fortunately, there will be three more days, and this spiritual liquid will be successfully refined." However, there is one thing that the old man should explain in advance, according to ancient records, after the "ghost liquid" is successfully refined, it must be used immediately to refine the eyes, and within three months, the eyes cannot see the light, this must be remembered!"

Hearing this, Kong Laosan nodded, "Thank you Master Ku, this matter is considered that I Kong Laosan owes you a favor, but in the future, if you need it, Kong will definitely do your best!"

"Hehe, my old man is about to enter the ground, since the seniors have a heart, you might as well listen to the old man's words, if the human race is in trouble in the future, the seniors may as well do their part, even if they repay the old man!"

After saying this, he walked slowly towards the outside of the cave, as if he was overworked, his steps were a little sluggish, and even his body was a lot stiffer.

Looking at the old man's back, Kong Laosan seemed to think of something, sighed lightly, and a trace of firmness flashed in his eyes.

Seven days later, the Taoist who covered his eyes with red silk slowly walked out of the cave, put down his thoughts, and saw the things around him at a glance, and his every move had no effect, but the appearance was a little unsightly.

After calculating the time, Kong Laosan did not return to his residence, except for Xuanling Pavilion, he walked all the way to Yun Tianqi's residence, according to the previous agreement, the opening of the black market should be in the near future.

It's just that when Yun Tianqi saw Kong Laosan's appearance, he was taken aback, and was about to ask, Kong Laosan hurriedly explained, hearing this, Yun Tianqi breathed a long sigh of relief, "Senior brother is lucky, I thought it was ...... Hehe, the senior brother thought that he was injured by that old monster Hu, but when he saw the appearance of the junior brother before, he was shocked!"

Three days later, the two figures galloped towards the northwest of Xuanyuan City, one after the other, and as for Yuanzun, they stayed at their residence. Two hours later, he finally landed in front of an ordinary secular liquor store.

The wine shop in front of him looks very shabby, a small pennant is placed diagonally, and the word "wine" is rubbed on it, Kong Lao Sanshen swept it away and didn't care, and walked towards the store with Yun Tianqi, the whole small shop was deserted, three shabby tables and chairs were placed at random, and half-person-sized wine jars fell around, like this, it didn't look like doing business at all.

In front of the counter, an old man was fiddling with the abacus, his octagonal beard trembled, and two fine lights flashed in his squinting eyes from time to time, "Hehe, the shopkeeper, this is my fellow brother, surnamed Kong, the first time I came here, apply for an identity token for him!"

As he spoke, a wooden box had fallen in front of him.

"It turned out to be Brother Yun, since it is a brother of the same sect, it is easy to say, but there is still a process that should be there, the black market rules, you must be above the realm of Jindan Ancestor to participate, this Taoist friend, you might as well show it!"

The hotel shopkeeper glanced at it lightly, and immediately smiled, glanced at Kong Laosan, and said with a smile.

Hearing this, Kong Laosan was indispensable, and the aura on the surface of his body swayed slightly, and suddenly, a unique coercion of the old monster condensed, feeling the strength of this coercion, the hotel shopkeeper's face turned pale, and he suddenly became respectful.

"It turned out to be Yuanying's predecessor, disrespectful and disrespectful, in this way, these spirit stones are not needed!"

The shopkeeper said, and the wooden box that had been put away was pushed in front of Yun Tianqi, and at the same time, with a flip of his palm, a small bronze medal suddenly appeared in his hand.

"Senior, just brand a drop of essence blood on it, and every time the black market opens in the future, seniors can participate with tokens!"

As he spoke, he threw it lightly, and the token fell into Kong Laosan's hand. Seeing this, the Taoist was not polite, the blood beads between his fingers condensed, and landed steadily on the token, and suddenly, the waves shone together, and disappeared without a trace.

"Come with me, two of you!"

Seeing this scene, the hotel shopkeeper was not lazy, and when the voice fell, he was already walking towards the backyard.

On the west side of the backyard, in a deserted thatched hall, Kong Laosan looked strangely at the teleportation circle under his feet, and couldn't help but sigh, "It's really a big deal!"

"Hehe, this black market is not only unique to our Xuanyuan City, the cultivators of the thirty nearby cities have participated, and they will definitely not disappoint the seniors!"

Hearing this, Kong Laosan's heart moved, but he didn't say anything, after dressing up in disguise, he didn't enter the formation, and the surrounding lights floated together, and disappeared in the blink of an eye.
