At that moment, the door creaked open a crack, and both of them couldn't help but turn their heads to look. They saw a black-haired fox, about the size of a small dog, squeezing in through the gap.
Zhang Ling scanned it with his divine sense and discovered that it was a fourth-order demon beast.
However, Huang Ying's face changed upon seeing the black fox, and she immediately stood up, respectfully saying to the fox:
"Greetings, Lord Qinghu."
The black-haired fox walked in step by step, glanced at Zhang Ling, and then looked at Huang Ying, actually speaking in human language. "You said you have collected spirit bamboo that is more than two thousand years old, is that true?"
"That's right, it's this fellow Daoist who brought a stalk of Emerald Spirit Bamboo."
Huang Ying patted her storage bag, and the two-zhang-long Emerald Spirit Bamboo was taken out, floating in mid-air.
The black-haired fox immediately flashed a green light in its eyes, looked at the Emerald Spirit Bamboo, and nodded slightly. Then, its gaze shifted to Zhang Ling.
Instantly, Zhang Ling felt a powerful divine sense sweep over him, and under this divine sense, a layer of goosebumps immediately appeared on his back.
Zhang Ling also stood up immediately, respectfully cupping his fist and said to the black-haired fox: "This junior greets Demon King-sama."
"Hehe."
The black-haired fox let out a strange laugh, its body flashing with green light, and it began to transform in front of him.
The black fur on the black-haired fox was instantly dyed cyan, then it spun around, and then its figure gathered and expanded, transforming into a zhang-tall cyan-haired fox.
Then the big fox stood up and transformed into a human figure.
In just two or three breaths, a handsome man in a cyan robe appeared before Zhang Ling. His face was fair and clean, with a sense of softness, but his pair of cyan eyes appeared extremely strange, with a kind of soul-stirring spiritual light.
Zhang Ling was shocked by this.
A transforming demon beast!
When facing the cyan-robed handsome man's pair of strange eyes, Zhang Ling immediately felt a sense of attraction in his mind, unable to move his gaze away, as if he had been cast a body-fixing spell.
For a time, the scenery in front of him became somewhat distorted.
But then Zhang Ling unknowingly circulated his cultivation technique, and suddenly a cool feeling rushed straight to his head, he instantly woke up and his back was already covered in cold sweat.
He had the feeling of being seen through from head to toe. Although Zhang Ling did not take off the hat on his head, this feeling was very strong.
"This kid has some ability, able to block this king's transformation's illusion pupil. Not only is your mana much deeper than that of monks of the same rank, but your divine sense is also a bit stronger than that of monks of the same rank. You are the monk who took out this spirit wood. Oh, this kid also has a small amount of fiend demon energy on his body. Could it be that you also practice the Demon Refiner technique?"
This cyan-robed man, transformed from a black fox, stared at Zhang Ling with a charming smile, as if he had seen through Zhang Ling's cultivation.
"Uh, Senior, you flatter me, this junior does indeed practice a Demon Refiner technique." After Zhang Ling came back to his senses, he did not dare to neglect it, and bowed to the man in return.
Facing a transforming great demon comparable to a Nascent Soul cultivator, he was naturally a little nervous in his heart. With this demon's gaze, Zhang Ling felt that all his secrets had been seen through.
Fortunately, before coming to Hidden Demon Valley, he had directly stored those special things on his body, including the two ancient treasures, in the Two Forms Gourd, to prevent the aura of his special treasures from being observed by some old monsters.
Once a natal magic weapon is stored in the body, even monks with much higher cultivation levels cannot detect it. This suddenly appearing transforming demon beast seems to be a Demon King in Hidden Demon Valley.
"No wonder you have fiend demon energy on your body. There are not many human monks who practice these two techniques at the same time. You have quite the courage."
The cyan-robed man said, glanced at Huang Ying who was standing quietly beside him, and suddenly asked, "You and this little friend seem to know each other. You also mentioned Xiao Fei just now. Could it be that you are also old acquaintances?"
"This concubine has indeed met this Fellow Daoist Zhang a few times, and Fellow Daoist Tu also knows Fellow Daoist Zhang."
The cyan-robed man walked to the table and sat down on his own, his eyes flashed with spiritual light, as if he had thought of something, and asked again.
"Oh, could it be that you are the monk Xiao Fei mentioned earlier who helped him escape?"
"That's right." Huang Ying nodded and admitted Zhang Ling's identity. Zhang Ling really didn't expect that a great demon would pay some attention to him.
"That kid hasn't comprehended the sword cultivator inheritance yet, and he provokes trouble all day long. Suffering some losses can also help him learn a lesson, but after all, Xiao Fei is considered half of this king's disciple. Since you have helped him, little friend, then it can be considered that this king owes you a favor. Little friend, you came here, could it be to collect some spiritual objects? There are indeed some spiritual objects in Hidden Demon Valley that are difficult to find outside. You might as well say it and listen, maybe this king can find one or two." The cyan-robed man said to himself, then changed the topic and asked Zhang Ling with a smile.
Zhang Ling felt a little strange in his heart, but he also quickly responded.
"Senior is joking, I only met Fellow Daoist Tu to save my life. Besides, Fellow Daoist Tu had already given me a reward at that time, how dare this junior covet the favor of your Demon King."
Zhang Ling's heart was beating a little faster. Why would this Demon King say these things for no reason? It made him feel both flattered and uneasy.
The cyan-robed man retracted his gaze and did not speak, but with a wave of his hand, the Emerald Spirit Bamboo suspended in mid-air came to him, and he examined it carefully.
"Fellow Daoist Zhang, since Senior Qinghu has already spoken, you might as well say what you need, maybe it can save you some effort."
Huang Ying couldn't help but say when she saw this scene.
Zhang Ling smiled dryly when he heard this, cupped his fist and respectfully asked the cyan-robed man.
"This junior came here to search for a special spiritual object. I wonder if Senior knows where to find Yao Stone, this kind of treasure refining material."
The cyan-robed man looked at the spirit bamboo without blinking and quickly replied, "Yao Stone, the essence of mountains, is indeed a special material. It may be difficult to find in other places, but this king happens to know that there is one in the Demon King Palace in Ten Thousand Demon City."
The Demon King Palace is a special place in Ten Thousand Demon City, and Zhang Ling couldn't help but frown.
But he saw the cyan-robed man look up at him, a flash of cyan light in his hand, and a white jade pendant appeared in his palm. This jade pendant was carved with a fox demon beast, with its head and tail connected, presenting a circular shape. There was no spiritual power on it, and it seemed to be an ordinary pendant.
The cyan-robed man gently pointed at the jade pendant, and once spiritual power entered it, the jade pendant suddenly turned cyan.
"With this king's Demon King Token, you can enter the Demon King Palace and choose any treasure."
Zhang Ling's heart moved, but he only glanced at the jade pendant, suppressed the urge to take it, and calmed his mind.
