Han Yu casually threw over a formation flag, and with a wave of his cuffs, all the puppets were put into the storage bag.

After contemplating for a moment, he stood up and walked out of the retreat room. When he stood up, seven or eight puppets scattered around the retreat room collected all the scattered wood chips, and when he walked out, the chamber became clean.

After walking out of the retreat room, Han Yushou summoned again, and a transmission note swept over from a distance.

With a flick of Han Yu's fingers, a green light flew into the transmission note, and the transmission note exploded into a fireball, and a voice came out from inside.

"Brother Han, the materials I promised you have been prepared, and I would like to invite you to come here. ”

The words were repeated twice, and then there was a soft thud, and it turned into a flood of fire, and disappeared without a trace.

Han Yu was a little strange when he heard it.

It's only been two months, and all the materials he wants are ready, which is too efficient, right?

But it's a good thing for him, just notice if there's any intrigue in it.

If the other party still asks him to help with anything about revenge and fisting, he won't agree. If they want to catch their own fish, they need him to bite the hook.

Besides, with such a big force as Changyun Auction House, he shouldn't be worried about him, a little monk who is a monk. Of course, although he wouldn't say that he offended Changyun Auction House, he still counted on the matter of the pill in the future.

Thinking like this, Han Yu perked up and left the cave and flew towards the auction house.

Half an hour later, Han Yu had just appeared at the door of the auction house, and that Huangshan disciple immediately greeted him.

"Senior Han, the elder ordered that as long as you come, I will take you to the second floor, please come with me. ”

Looking at the courteous look on Monk Huangshan's face, Han Yu nodded and followed him to the second floor of the auction house.

Knocking on the door and walking in, Han Yu's eyes swept and his gaze froze.

There were three monks in the room, namely a strong man surnamed Xu, an old man in gray, and a monk with a burnt face.

The aura on this monk's body was a little erratic, and when he saw Han Yu coming in, he hurriedly stood up, gave a long salute and said, "Thank you Brother Han for saving your life, Zhang Huan will definitely report back in the future!"

This person is the leader of the monk surnamed Zhang.

"Han was also trying to protect himself at that time, and Brother Zhang didn't have to mind. Han Yu was overjoyed when he heard this, and secretly thought that he could knock some benefits from it, but he said with a solemn face.

"The situation that day was really dangerous, I don't know if other Taoist friends escaped from the tiger's mouth. The monk surnamed Zhang sighed.

When Han Yu heard this, his face also showed grief.

As for whether the other monks could escape, Han Yu really didn't believe it.

It was a fluke that he was able to escape, but fortunately, the kid surnamed Sun was arrogant and pursued alone, and if there was another mid-stage monk, he would be dead.

This monk surnamed Zhang really has two brushes, and the magic weapon that blew himself up can escape back, which is really not simple.

"Brother Zhang, how did you escape back?" Han Yu took a sip of tea after sitting down, and asked curiously.

"I was chased by two thieves that day, and I was able to escape by using a secret method. I didn't dare to go back to Richeng, but Zhao retreated to a remote island to recuperate, and was rescued only a month ago. The monk surnamed Zhang said vaguely.

Hearing this, Han Yu naturally wouldn't ask without interest.

The secret methods of the exercises are all secrets, and if you continue to ask questions, it will inevitably make people feel ill-intentioned.

"Brother Han, this time Brother Zhang was able to get out thanks to your help. I've heard that it was Brother Han who made the move at the last moment. The man surnamed Xu changed the topic back again.

"I'm just going to do it. Han Yu said modestly again.

"Brother Han, this is the material you want. The gray old man took out a storage bag and put it on the table with a smile.

Han Yu was trying to find an excuse to mention this matter, and when he saw that he took the initiative to take it out, he said a few polite words, and then probed Shen Nian in.

Half an hour later, a heartfelt smile appeared on Han Yu's face, and now he had all the materials for refining the flying sword.

"Brother Han, please wait a moment. Elder Tian will open the secret vault in a while, and I will go with you. The old man in gray continued.

"Then thank you!" Han Yu hurriedly thanked him.

"By the way, what does Han Yu want? materials, magic weapons, or elixirs?" the man surnamed Xu coughed and asked.

"Let's take a tour and look around. Han Yu didn't answer directly.

Next, the four of them gathered together to chat and exchange some experience in the exercises. Han Yu's mana is the most shallow, and he naturally listens to it with relish.

However, the three people present were very polite to Han Yu, and the old man in gray even had a hint of respect in his tone, which made Han Yu a little confused.

After thinking for a moment, he secretly guessed in his heart, did he kill the monk surnamed Sun?

After talking about it for more than two hours, Han Yu benefited a lot, and the road to the middle stage of Yudan became clearer.

Soon a transmission note flew over, and a familiar female voice came from inside.

The gray old man stood up and said with a smile to Han Yu, "Let's go, Elder Tian called us forward." ”

"Brother Han, I am in charge of managing some rare classics in the bank, which can be read by Brother Dao for free. The monk surnamed Zhang also stood up and said politely.

"Then I'm going to bother. Han Yu's eyes lit up, and he hurriedly said.

He now feels that the classics he read from the Wang family are too one-sided, and many things are brought in one sentence without a detailed interpretation.

All the shops that sell books in the city don't let people read them for free, and you have to buy the flowers you want to see.

Now that you can watch it for free without spending money, Han Yu immediately agreed.

The two of them came to a hidden corridor of the auction house, pushed the door a small door, and walked down through a carved screen and secret passage, and appeared in front of a swarthy door.

"Brother Zhao, this treasure house is not deeply hidden, and it is not guarded, so you are not afraid that the young people will sneak in?" Han Yu was a little puzzled when he saw this, and asked.

"Brother Han doesn't know, what you are facing is a gate made of dark iron, and we will not be able to break through this defense even if we use up the mana. Besides, that's just the first line of protection. Master Zhao replied proudly.

Then he took out the half of the Five Elements Jade, raised his hand and shot it into the groove next to the Xuantie Gate.

Then another trick was submerged in the jade.

The dark iron gate began to move, and the blue light on the gate flashed, and there was a "boom" sound.

After a few breaths, the dark iron door slowly opened.

Then Master Zhao walked in with Han Yu.

This is another long corridor, and at the end of the corridor is a teleportation array, and there is a female correction standing in front of the teleportation array.

"See Elder Tian!"

"Meet the seniors!"

The two of them went over to salute together.

"There has never been a non-professional monk entering, little one, you are the first. The female cultivator surnamed Tian said with a chuckle.

"It's an honor for the younger generations. Han Yu arched his hand and said.

The nun didn't continue to say anything, two multicolored talismans flew out of the storage bag and stuck them on them, and then stepped into the teleportation array and disappeared.

"Brother Han, if we didn't have this talisman, we would have tore and shattered the turbulent current of teleportation. The gray old man explained with a smile.

The two of them stepped into the teleportation array without further delay, and the light disappeared in a flash.

Soon they were in the vault.

The treasure house was not as spacious as Han Yu imagined, with only a few tens of zhang in length and width, but it was still divided into dozens of areas, each of which contained hundreds of jade boxes, suspended in mid-air by an invisible force.

Han Yu's eyes swept and he found that he was teleporting the material area, and he was thrilled by the standards of some of the materials in the jade box.

"Brother Han doesn't have to be polite, you can choose any of the things in it, but you can only choose one. The old man in gray said with a smile.

"Can I open it for inspection?" asked Han Yu after thinking for a while.

"It's really not going to work. The old man in gray shook his head and said.

Han Yu was a little disappointed in his heart, he originally wanted to take this opportunity to gain more knowledge.

"Brother Zhao, is there any technique that goes straight to Yuanying?" asked Han Yu with a straight expression.
