"Two little brothers, are you planning to stay in Black Rock City for a while this time or continue your practice?" Otto asked with a smile while sitting in a quiet teahouse.

"Master Otto, we will stay here for a while this time because we need to find two things within this period of time, so we may participate in this auction!" Xiao Yan said.

"What do the two little brothers need? As long as I can, I can get the items you need now!" Otto waved his hand and said in a affirmative tone.

With his identity as a fourth-grade alchemist, he does have such energy to let the auction house deliver the goods, after all, he is not afraid that others can't afford it!

"We need a third-level magic core and Ice Spirit Cold Spring!" Xiao Yan said.

"Bingling Cold Spring?"

Listening to the name popping out of Xiao Yan's mouth, Otto was obviously stunned, and then said in surprise: "Little guy, this Ice Spirit Han Spring is an extremely rare treasure of natural treasures. And with your current strength, it seems that it is impossible for you to need that kind of thing at all, right?"

Xiao Yan smiled and said vaguely: "I really need this thing, Master Otto, do you know that it is in the Alchemist Guild, has anyone ever owned it? If anyone has it, I can trade it with it at a high price."

"This, I did not have the Ice Spirit Cold Spring until there is nowhere, but I guess you can't buy this Ice Spirit Cold Spring even if you spend a high price!" Otto said helplessly.

"Why?" Xiao Yan asked in confusion.

"Well... the guy who owns Bingling Hanquan has a very quirky personality and is only interested in things like the world's treasures. And Bingling Hanquan only has as many jade bottles in his hands. I guess he will not be willing to take them out!" Otto said.

"Master Otto, take us to find that person. Believe me, he will definitely take out the Ice Spirit Cold Spring!" Yang Yu said confidently.

"Oh? There is something more precious in your hands than Bingling Cold Spring?" Otto asked in surprise.

"Master Otto, after we create the Ice Crystal Cold Spring, you will understand!" Yang Yu said with a smile.

"Okay, I'll take you to the old immortal's residence." Otto nodded, stood up, and then said: "As for the magic core of the third-level monster, I'll send someone to pick it up later. After we come out of the old immortal's residence, we will probably be able to send it here!"

"Then thank Master Otto first!" Xiao Yan and Yang Yu bowed and said.

"Let's go, I'll take you there!" Otto said with a smile, obviously very satisfied with Yang Yu and the others' politeness.

After Otto and the two of them walked around more than a dozen streets in Black Rock City that made people feel confused, they gradually stopped in front of a strange building in a remote corner near the south of the city.

Looking up at the strange building in front of him, Otto breathed a sigh of relief, turned his head and smiled at Yang Yu and Xiao Yan, "This is the residence of that guy Gut. Before entering, remind me again, you'd better be prepared to bleed!"

"Hehe, who is bleeding profusely is still not sure now!" Yang Yu said with a smile.

Waving to the two, Otto took two steps forward and pushed open the door. However, before the person could enter, a fierce energy gushed out from the inside of the room with overwhelming black powder.

The sudden change made Xiao Yan slightly startled. He took a few steps cautiously, and quickly held the Xuan Chong ruler between his back with his right palm. His body was slightly bowed, but Yang Yu stood there without any worries.

As the black powder in the room was about to be sprayed out of the room, Otto curled his lips, waved his sleeves suddenly, and a more fierce energy emerged out of thin air, and then all the black powder flew back.

The black powder gradually dissipated, and then the dirty and messy room inside was exposed. He clapped his hands, and Otto turned his head to the cautious Xiao Yan and smiled: "This old guy always likes to do these tricks. Although the black powder just now would not be poisoned, if the skin was a little bit contaminated, it would be uncomfortable."

"Let's go, Master Otto!" Yang Yu smiled and looked at Xiao Yan, followed Master Otto's footsteps and walked into the room.

Afterwards, after Otto and Guter's greeting, Yang Yu and Xiao Yan also entered the room.

Otto turned to the outsider and said, "Yang Yu, Xiao Yan, come in."

"Uh. You brought someone else here? What do you want to do?" Gut glared at Otto's actions and said with a cautious look on his face.

With a lip, Otto was too lazy to pay attention to this nervous guy.

"Master Guter!" Yang Yu looked at Guter with a smile, with a hint of inexplicable meaning in his smile.

Xiao Yan, who was standing beside him, looked dull and was now behind Yang Yu, without saying anything.

But only Xiao Yan himself knew how nervous he was now!

"Two little kids, why are you looking for me? Just tell me, I don't have time to chat with you!" Guter looked at Yang Yu and said lightly.

"Master Guter, do you have a cold spring in your hand? I hope you can exchange it with you!" Yang Yu said.

Upon hearing this, Gut was stunned at first, and then shook his head like a windmill: "No, you have found the wrong person, I don't have that thing!"

Looking at Guter's rogue appearance, Yang Yu also smiled and shook his head. When he mentioned Bingling Hanquan, he clearly saw Guter's face flashing. Perhaps, he was shocked how he learned that he had Bingling Hanquan.

"Old guy, stop being mean. Didn't you tell me the last time? You exchanged a small bottle of Ice Spirit Cold Spring from someone else, I remember it firmly." Otto smiled.

"Old bastard, get out of here, don't come again!" Guter looked at Otto angrily, as if he wanted to fight Otto now!

"Master Guter, you don't have to be so excited. If I hadn't been able to compare with Bingling Cold Spring, I wouldn't have come!" Yang Yu said.

"Okay, then tell me, what do you use to replace it!" Gut's eyes rolled and asked faintly.

"Compare amethyst source!" Yang Yu took out the half bottle of amethyst source that he had just asked Xiao Yan and put it in front of Guter!

"Wait!" Guter's heart was shocked when he heard Yang Yu's words. He immediately took out an ancient book and looked through it for a while. Then he knew what Yang Yu said about the amethyst source!

"The amethyst source. The amethyst Winged Lion King is born with a small beast. The chance is extremely small. It is rare to find it in a century. For those who practice fire-attributed skills, they are treasures that are hard to find!"

"Tsk tsk. Little guy. I can't tell. You can actually get a strange thing like the companion amethyst source..." Guter couldn't help but be surprised.

"Master Guter, I am a companion amethyst source. Its preciousness does not require your Ice Spirit Cold Spring at all. If you encounter a fire-attributed warrior, you may be able to use this companion amethyst source to exchange for something very good!" Yang Yu said with a smile.
