After saying goodbye to Xie Dan, Zhang Yu returned to the Scripture Pavilion, and his head kept thinking about the black market and the Lingshi Mine, there are records in the Scripture Pavilion of the Lingshi Mine, this mine produces Lingshi veins, and the primary, intermediate, and high-grade spirit stones of the three domains are produced here, of course, accompanied by various other gems and ores, the Dandao Sect will generally sell these ores to the Refining Sect in exchange for the utensils and magic weapons they need.

On the entire Longteng branch, there are five such spirit stone mines, except for one for each sect, the remaining one mine is determined by the four sect competitions every ten years. It's a pity that the Kendo and Qi Dao sects are strong, and the mine called the Spirit Snake Cave was excavated by the two sects in turn.

The spirit stone mine cave is not like an ordinary mine cave, just dig it, there are a large number of rampaging rats, they are shuttling in the mine to find food, the Dan Dao Sect once organized a large-scale extermination, killing many rats, but the rampaging rats are very fecund, there are still small groups of fugitives, these rats are ordinary Qi refining period cultivators can not resist.

Every time they go down to the mine, the monks have a clear division of labor, and some monks are specially guarded to protect others from mining. The mining process is extremely careful, because the spirit stone contains a large amount of spiritual energy, and whenever it is mined, it will attract rampaging rats to come and devour the spirit stone.

It's a pity that the mine is too narrow, and the troops are destined to be scattered, and there will be deaths and injuries every time they go down to the mine, plus the conditions are extremely difficult, and finally the sect changed the regulations, and only the disciples who made a big mistake will be sent to mine, such as Meng Tiandong and others this time.

If you want to mine the colorful spirit stones, you must go down to the third floor of the mine, where there are not only rampaging rats, but also other terrifying creatures, who are constantly competing with humans for the spirit stone resources generated by heaven and earth.

Sighing, Zhang Yu knew that with his current strength of the third layer of qi refining, it would be a death.

He had no choice but to set his sights on the black market, but unfortunately he didn't know anything about the black market, and after reading the book on the first floor of the Hidden Scripture Pavilion, Zhang Yu said hello to the guard disciples and left, returning to his room.

To his surprise, the door was ajar, and he could hear movement inside.

Could it be a thief? Zhang Yu frowned, pushed open the door suddenly, and saw another vacant bed full of things, a fat man was lying on top of the things and eating roast chicken with Erlang's legs crossed, he devoured it, as if the roast chicken was the most delicious thing in the world, and Zhang Yu swallowed his saliva when he saw it.

Seeing Zhang Yu walk in, the fat man's eyes lit up, and he devoured the roast chicken in two or three bites, jumped out of bed, and wiped his clothes with greasy hands.

"Brother Zhang, you're here, my name is Zhou Tao, just call me Zhou Fat'er. Zhou Fat'er said excitedly, as if he had seen an idol.

"Who are you?" Zhang Yu felt that this guy was a little familiar, but he had a good impression of the fat man this week, so he couldn't help but ask curiously.

"I'm the new handyman, hehe. Although Zhou Fat'er said this, he couldn't kill Zhang Yu, and the two chatted for a while Zhang Yu only knew that Zhou Fat'er was originally an ordinary merchant family, and his parents spent a lot of money to get him to the Dandao sect as a handyman, in order to let him become a cultivator and glorify his ancestors.

After Zhou Fat'er came to the sect, he arrogantly invited all the miscellaneous servants to dinner, and after hearing about Zhang Yu's deeds, he strongly asked to live in a room with Zhang Yu.

"The ratio of 1 to 30, that's me, I'll make a few thousand contributions, I don't have to do tasks in this life, boss, you are simply my idol, can you tell me how you did it?" Zhou Fat'er stared at Zhang Yu and said with admiration on his face.

Zhang Yu couldn't help but have a headache, because after a short period of contact, this guy was not only delicious, but also a talker, Zhang Yu didn't ask anything before he explained his ancestors to eight generations, and then looked at Zhang Yu with an innocent face, his eyes were full of desire for money.

It's a waste for this guy not to be a businessman, Zhang Yu sighed and thought, could you tell the truth to this guy, Zhang Yu had no choice but to say mysteriously: "Secret!"

"I knew it, I knew ......" Zhou Fat'er was not disappointed, but muttered excitedly.

"By the way, let me tell you, there are so many opportunities to make money here, you see that these cultivators don't even know how to operate the assembly line, and they actually use a single labor, tsk, and waste manpower...... "Zhou Fat'er muttered.

"I'll wipe it!" Zhang Yu was taken aback, thinking that this guy wouldn't have come through the teleportation array as well.

"Wait, let me ask you something, I don't know Wu Xlan in my life, what is the next sentence?" Zhang Yu asked tentatively.

"What does Wu Xlan mean?" Zhou Fat'er looked at Zhang Yu blankly.

"If you don't know, forget it!" Zhang Yu couldn't help but breathe a sigh of relief.

"No, you have to tell me what Wu Xlan is? Could it be the latest spirit grass? No way, there are no products in this world that I don't know. Zhou Fat'er said anxiously.

"Oh, then do you know about the black market?" Zhang Yu couldn't help but ask.

"Is there a black market?" Zhou Fat'er's eyes lit up, he touched his chin and continued: "I'll go out and ask first, this is a money-making business." ”

"Don't ask nonsense......" Zhang Yu hurriedly reminded.

"Don't worry, I'm not going to ask. Zhou Fat'er was like an agile fat rabbit, as if he had found something interesting and ran away.

Maybe Zhou Fat'er has a businessman's unique sense of smell, he disappeared for a whole day, and he ran back from dinner in the afternoon, and after killing three bowls of rice and two plates of braised pork, he wiped his mouth and said: "In the past few days, I have lost weight, just eat eight points full." ”

Zhang Yu bowed his head to eat with black lines, pretending not to know this product, but Zhou Fat'er came over and said mysteriously: "I know the black market is there." ”

"You know?

"There's a black market deal every month, everybody is masked, no one knows anyone, and if you need something special, you can leave a record and someone will contact you. The fee to enter the black market is relatively expensive, and you need to pay ten primary spirit stones, and you will get a jade pendant that shields your identity. The fat man's words made Zhang Yu's heart move.

"When does it start?"

"Three days later, are you interested in going and seeing?

"You go and get two fast jade pendants, 300 points will be contributed to you here......" Zhang Yu is also wealthy now, and the contribution is 15 to 1 for primary spirit stones, and the fat man is not polite, he accepted the contribution with a smile, and turned around and didn't know where to go.

It wasn't until the middle of the night that the fat man ran back, handed a jade pendant to Zhang Yu with a smile, and explained how to use it.

Zhang Yu took the jade pendant and looked at it over and over, reciting the mantra, and for a moment he could feel the light shroud enveloping his whole body, a miniature shielding enchantment, and the carving was very fine.

"This jade pendant can only be used for three hours, and every time you enter the black market, you have to buy it again. The fat man said with a smile, Zhang Yu shook his head, thinking that it was really dark.

"By the way, everything can be sold there, I wonder what the boss has to offer?"

"I'll know until that day, rest early, and do things tomorrow. Zhang Yu said with a smile.

The fat man was also very tired after running for a day, and he snored when he fell on the bed.

Zhang Yu sighed, lay on the bed, and entered the system, due to the launch of the new system, many things have changed, his strength has fallen to the third layer of qi refining, many things cannot be exchanged, and there are thousands of soul points left. He looked at the system and used his soul value to buy some ghost slaying charms and exorcism charms, copper coin darts and other things. There are several large fireball talismans and thunder talismans in the inventory, these runes are used to save lives, Zhang Yu looked at it for a long time, and finally sighed, closed the system and began to cultivate the Heavenly Master Secret Codex.

At this moment, there was a sudden commotion in the depths of the Longteng Mountain Range, and countless demonic beasts sensed the danger and couldn't help but flee in all directions.
