"I also asked Brother Zhao to help introduce him. Han Yu was overjoyed when he heard this, and hurriedly said.

"Okay, Brother Tang is in the secret place of refining weapons in the line, I'll take you to take a look. The gray old man did not hesitate to listen, and said with the teacup in his hand.

Han Yu thanked him again, explained a few words to Shopkeeper Ye and left.

The two of them came to a remote corner of the city, in front of a palace.

"Master Zhao!" The two monks in red robes standing at the door saw the two coming, and hurriedly greeted them and gave a salute.

"Where's Brother Tang?" the gray-clothed old man glanced up at the hall and asked casually.

"Elder Tang has been refining a batch of magic weapons recently, and—" One of the disciples explained, and then his expression became a little hesitant.

"He has explained before that unless it is a matter of life and death, he can't be disturbed. Another disciple said.

The gray old man smiled awkwardly when he heard this, and then left with Han Yu.

"Brother Han, let's go, I'll take you to introduce Brother Shi. His temper is a little strange, hey..."The old man in gray said with some reluctance.

Han Yu knew that he owed a favor this time, but he didn't promise anything, so he could only smile slightly awkwardly.

Han Yu followed the old man to the head office first, he explained a few words to his disciple, and then took Han Yu out of Richeng and flew towards an attached small island.

After a short while, the two of them came to Redfish Island, and together they came to a slightly desolate valley on the edge of the island.

The entire valley was made of crimson boulders, and a fiery aura could be felt far away.

The old man took him and landed at the gate of the valley, and strode towards the depths of the valley.

A moment later, the two of them appeared in front of a gray-white stone gate at the end of the valley that cultivated by the mountain.

On the surface of the stone gate, there is a dense array of patterns, which should be a defensive formation. Without waiting for Han Yu to ask, Master Zhao glanced at it, then stepped forward and walked to the door, knocking twice without hesitation.

After two "bangs".

The stone door was opened a little halfway, revealing a strong man with a dark complexion.

As soon as this strong man saw Master Zhao, his eyes showed eagerness, but when he saw Han Yu, who he didn't know on the side, his eyes showed hesitation.

"Shi Ming has seen his predecessors, but he came to find his ancestor?" the strong man did not ask about Han Yu's origin, but asked respectfully.

"This is my friend Han Yu, and I brought him here this time to visit Shi Zhen Daoyou. Master Zhao explained.

"It turned out to be Senior Han! It's a coincidence that you came, the ancestor of the family has just refined a top-level magic weapon in the refining room, and is meditating in the meditation room, so I'll go and tell you. After hearing this, the strong man hesitated, but still said.

"Then there will be work!" Master Zhao said.

"Two seniors, please wait a while, I'll go back as soon as I go. The strong man said apologetically, then closed the door again, and went to report the news.

After a meal, the door of the cave opened again with a "squeak".

This time, an old man in his sixties and seventies walked out of it, short in stature, with gray hair, but thick hands and feet, and at first glance there was an ordinary person in the mortal world.

"Brother Zhao, did you come this time because of the last time?" The short old man didn't pay attention to Han Yu on the side, but asked a little eagerly.

"Shi Daoyou, you also know this situation, how can that kind of thing be so easy to get. Master Zhao seemed to have long realized this question, and said helplessly.

"Then what are you doing here?" the old man's tone suddenly turned cold.

"Brother Shi, do you just let me and my brother sit outside and don't invite us in to sit down?" Master Zhao did not answer positively, but said with a wry smile.

"It's rude, but I'm rude, please two of you. The old man was stunned when he heard this, but he still stepped aside and invited in his mouth.

Han Yu looked at the old man's attitude and was a little surprised, but his face did not show the slightest color, and he thanked him and walked into the stone gate.

As soon as you enter the gate, you will pass through a long corridor of more than ten zhang, and inside is a vast hall of twenty-three zhang. There was not the slightest heat in this hall, but there was a coolness.

A moment later, the two of them, led by the old man, came to another simple stone room.

"I usually don't have anyone here here, it's a little shabby, and I hope the two Taoist friends are not strange. The old man said coldly.

There was no surprise on the face of the gray-clothed old man, and Han Yu thought that the guy's temper was really weird. Just now, the strong man came over and served a pot of tea, and the old man also explained his intention to the old man.

"So, Brother Han wants to learn refining tools from me?" the old man asked with a strange look at Han Yu.

Han Yu stood up, saluted him and said, "I plan to refine a magic weapon again, but I don't know anything about the way of refining."

"Han Daoyou, I'm not interested in teaching people to refine weapons, so please go back. The old man stood up without waiting for him to finish, and refused somewhat indifferently.

Han Yu saw the indifference on his face and knew that there was no point in bothering about words, so he was inevitably a little disappointed in his heart.

Do you need to start all over again?

"Brother Zhao, please take a lot of trouble when the one-eyed demon Neidan. After the little old man finished speaking, he begged Master Zhao, who sat up and shook his head.

"One-eyed Demon Neidan?" Han Yu was overjoyed when he heard this, and he already had a plan in his heart.

"Brother Zhao, I have something here, and I want you to identify it for me. Han Yu suddenly smiled mysteriously, and took out a white jade box from the storage bag and handed it over directly.

"Brother Han, this is another good thing.... Master Zhao was a little surprised that Han Yu said this kind of thing back at such a time, but he still took it, and when he got it in his hand, he sank slightly, and when he opened the low beast in the jade box to see the appearance of the things in the box, his voice trembled slightly.

This thing is an egg-sized Neidan, which is the Neidan that Han Yu used to go to sea to strangle the Thousand-Eyed Demon, and it appeared in his hand by accident.

He didn't dare to show this thing to others, and if it wasn't for his reminder, he really forgot about it.

The old man on the side was also stunned when he saw this thing, and then his eyes showed a fiery gaze.

"It seems that Brother Zhao has recognized this thing. This is the inner dan of the thousand-eyed demon that was inadvertently killed in the lower sea. Brother Zhao also asks you to carefully identify it to see if the Dan power in it has been lost. Han Yu glanced at it and said with a smile as usual.

"No need to identify it, I have also refined this pill more than a dozen times. However, he is far from as big as you, and Dan Li is also a little lacking. This should be the demon pill in the late stage of foundation building. Brother Han, if you let this Neidan be given to Brother Shi, you should be able to agree to that condition just now. The gray-clothed old man carefully checked the condition of Neidan, glanced at the old man and said.

The old man's face on the side was not so cold, looking at the jade box in the gray old man's hand, his eyes were full of fiery color.

"I would like to give this Dan to you, just because I hope that Brother Shi will instruct Han on one or two alchemy techniques. Han Yuhan said with a smile.

"Brother Han is trying to refine a special magic weapon?" After hearing this, the little old man turned his head and asked.

"Brother Shi is really as wise as a torch!" Han Yu flattered.

"Ordinary magic weapons can be tempered with Danhuo, and special magic weapons need to be refined. However, Daoist friends should think clearly, the refining weapon is extremely profound, and if there is no huge financial support, it may not be possible to enter this gate. When the old man heard this, his face was a little ugly.

"It's not a matter of a year or two to cultivate immortals, and I can understand this common sense no matter how much I go. However, in order to make another magic weapon, Han must learn the way of refining, and he hopes that Daoist friends can complete one or two. Han Yu said with a sigh.

"Since you really want to learn alchemy from me, it's not impossible, but I have a few rules here, and I need three chapters of the law. The old man couldn't persuade Han Yu, frowned, and said in a cold tone.

"Shall I retire first?" Master Zhao stood up and said.

"No, you can do some testimony for me. The little old man waved his hand to stop.

"First, although I don't dare to call my Shi Zhen's alchemy the first in Richeng, I can still rank in the top ten in the same level, so you and I learn alchemy, this inner pill is a little insufficient. The old man stared at Han Yu and said slowly.

"Since one is not enough, how about adding one? But this is not a thousand-eyed demon, it is also a rare demon beast. Han Yu raised his eyebrows, patted the storage bag, and took out a jade box and put it on the table.

The old man was a little disappointed, but he still opened it to look at it, and there was a look of surprise in his eyes.
