As a city of immortal cultivation with a total population of several hundred thousand people, Yingxian Island's market is quite large. There are nearly a hundred shops and more than two hundred stalls. Chen Xiao took a quick look and found a lot of good things, even magic weapons of the best quality.

However, his luck this time didn't seem very good. Those people were either waiting for a good price or asking too high a price. Chen Xiao didn't have a strong demand and refused to let Xi Yunting spend money to buy it for him. For Chen Xiao, he liked the process of discovery and picking up bargains more.

After spending quite a while in the market, they arrived at the agreed meeting place, Zuixian Winery, around noon. Xi Yunting asked for a viewing box as usual, and after the four of them sat down, Tong Nuonuo couldn't wait to take out his harvest.

"Look! I bought a damaged mechanical puppet!" He was so excited that he almost danced with joy. "According to my judgment, this is most likely the work of a mechanical master. It just so happens that I need to learn this part when I advance to the mechanical master stage. My luck is just too good!"

Tang Ru said, "It's just a broken puppet. Is it worth spending two thousand spirit beads to buy it? The seller just used a few sweet words to trick you. Are you stupid?"

Chen Xiao repeated in astonishment: "How much? Two thousand spirit beads?!"

Tang Ru nodded fiercely: "Yes! It's all because of that idiot Nuonuo's impatience! I told you to wait until I meet up with Xiaoxiao before going there again, but you insisted on buying it right away."

Tong Nuonuo retorted: "If we really wait until we meet up before going there, it will be too late! Didn't you hear the seller say that he just collected this mechanical puppet and he can't guarantee that it can be kept until we go there. You know, there are many mechanical masters on Yingxian Island. Who knows, as soon as we leave, a mechanical master might come and buy it."

Tang Ru rubbed his forehead with a headache: "This is all the seller's excuse for you to buy it immediately. If he didn't say that, why would you be so anxious?"

Tong Nuonuo replied unconvincedly: "You don't believe me? I'm not that easy to fool. I can always tell whether it's the work of a master of mechanisms, right?"

Chen Xiao hurriedly stopped them from arguing: "Let me see first."

Tong Nuonuo handed him a doll about a foot long.

Chen Xiao first noticed that there was only a very weak aura fluctuation. However, unlike magic weapons, talismans are rarely used. So the weak aura fluctuation does not mean anything.

However, the puppet in front of him was really shabby, with an unknown wood body and metal armor on his body. When he shook it, there was a rattling sound inside.

Tong Nuonuo said regretfully: "From the sounds inside, the parts inside are seriously damaged. I don't know if I can repair them. I don't ask for a complete repair, but if I can restore more than half of it, I will have hope of being promoted to a master of mechanisms."

Chen Xiao had no idea what this mechanism was, and he didn't dare to draw any conclusions. From what he knew, he could only know that this was definitely not a child's toy.

He persuaded Tang Ru: "A Rou, I believe Nuo Nuo has a plan in mind. You should have some confidence in him. He was able to repair the Fulong bone and put it into use again, which shows that he has profound attainments in mechanical engineering."

Tang Ru sighed and said, "It's not that I don't believe in his vision and insight. It's just that he is too impatient. Can't he slow down a bit and wait for you to come over and discuss it." In the final analysis, Tang Ru was just a little angry that Tong Nuonuo didn't listen to his advice.

"Maybe what the shop owner said is true. It would be terrible if a mechanic takes a fancy to it and someone else buys it." Chen Xiao said hypocritically.

He was not sure whether it was really a masterpiece by a master of mechanical devices. What he was sure of was that the shop owner was definitely exaggerating. Two thousand spirit beads were not something that an ordinary mechanical device master could afford. At least in such a short period of time, it was very unlikely that someone as wealthy as Tong Nuonuo would emerge in the market. It was impossible for someone to buy this doll before Tong Nuonuo went there again.

However, in order to avoid disturbing the ears and making Tong Nuonuo unhappy, Chen Xiao decided to conceal this part. He turned to talk about his experience with Xi Yunting.

Tong Nuonuo and Tang Ru had seen the Feng Shui part before and did not find it new. They were just interested in the piece of bark.

Chen Xiao put the bark on the table and showed it to Tong Nonuo and Tang Ru. After studying it for a while, Tong Nonuo said, "This should be the bark peeled off from a spiritual tree. Judging from its size, this tree must have grown for at least hundreds of years."

Tang Ru put his hand on it and frowned in surprise: "This is the bark of a metal spirit tree. It is wild and has not been cultivated artificially. This kind of tree is generally favored by weapon refiners. Even a small piece will not be wasted in the furnace. How could such a large piece end up in a place like the market?"

Tong Nuonuo sneered: "Once the bark loses its vitality, it becomes dull and ordinary. Most of those weapon refiners are blind, how can they recognize it?"

Chen Xiao crossed his fingers and placed them under his chin, raising his eyebrows: "I said this bark is not simple. You said it has lost its activity, but in fact, in my eyes, the fluctuations of this bark are quite active."

Xi Yunting picked up the bark and took a look at it. He said, "The fact that it appeared in the market only means that its previous owner is likely dead, and the second person who obtained it is definitely not a weapon refiner."

Putting down the bark, Xi Yunting continued, "The second owner who picked it up didn't understand its value, so he sold it to a buyer in the market at a very low price. Therefore, the person who picked it up should not be the murderer who killed the weapon refiner. The weapon refiner could only have died in an accident."

Tong Nuonuo was stunned for a moment, and asked in confusion: "Why?"

Chen Xiao explained to him, "If the weapon refiner died in a fight, then the person who killed him couldn't be unaware of his identity. And even if the person didn't recognize the things the weapon refiner was carrying, they wouldn't sell them at a low price. You know, how could the unknown things carried by the weapon refiner be cheap items?"

Tong Nuonuo pouted and said unwillingly: "That's right. Just like the materials that a mechanical engineer carries with him are all very valuable."

Everyone else knew Tong Nuonuo's resentment towards the weapon refiner, and they all ignored his words.

Tang Ru tilted his head and said, "Even if we know how this piece of bark ended up in the market, it doesn't explain why it's still alive. I've never known any spiritual tree whose bark can be peeled off for two or three hundred years and still be alive."

"Huh?" Chen Xiao suddenly cried out in surprise, "This fluctuation... actually has a pattern to it?"

Tong Nuonuo blinked, and suddenly thought of something. He brought the bark to his eyes again, frowned, and examined it solemnly.

The three of them watched his movements quietly. After a while, Tong Nuonuo said in disbelief, "This is actually a refined magic weapon... a magic weapon that can't be recognized as a magic weapon at all!"

Tang Ru's eyes widened: "What did you say? This is a magic weapon? But why do I feel like it's just a piece of tree bark?!" Tang Ru was also shocked. She was a spiritual plant master, but even her senses were completely deceived!

Tong Nuonuo bit his lip and said, "Although I am very unwilling, I have to say that this is indeed a magic weapon, and it must be made by a grandmaster!" He raised his head and pushed the bark in front of Chen Xiao, "If Xiaoxiao hadn't found something wrong, all of us would have been deceived. Such a perfect disguise can only be done by a grandmaster. This piece of bark is simply not something that ordinary people can see through. I'm afraid only a weapon refiner can discover the secrets inside. Xiaoxiao, can you describe what this fluctuation is like?"

Chen Xiao took the bark in his hand and said, "Let me try it."

The real natural aura fluctuations will be affected by the surrounding environment and will be different at every moment. Just like there are no leaves in the world that look exactly the same, there are no completely identical aura fluctuations in the world.

Chen Xiao counted and watched carefully. He found that after the fluctuation changed twenty-four times, it began to repeat.

Without raising his head, he stared at the bark and said, "Nono, give me paper and a hard-tipped pen."

Tong Nuonuo placed a pen and paper in front of him, and Chen Xiao drew the twenty-four waves into crooked curves according to the waves.

After Chen Xiao finished drawing, Tong Nuonuo took a look and said, "This is a broken up map. Wait a minute, I'll try to put it back together."

It was not easy to reorganize the 24 irregular lines into a complete map. They stayed in Zuixian Winery for an entire afternoon, but Tong Nonuo did not figure out anything. In the end, Chen Xiao and Tang Ru had to force Tong Nonuo to move.

The next morning, Chen Xiao and the other two were having dinner in the lobby on the first floor. Tong Nuonuo, who hadn't slept all night, rushed out of the room excitedly: "I succeeded! Hahahaha - Ah Rou, Xiao Xiao, Fellow Daoist Xi, come and see - Ouch!"

Tong Nuonuo was so happy that she tripped herself and had to jump on the railing in a very dangerous way to avoid breaking any bones.

Chen Xiao looked at Xi Yunting in surprise, and Xi Yunting shook his head speechlessly. This was definitely not affected by his bad luck! He had not been promoted to a small realm recently.

Tong Nuonuo jumped directly to the table and slapped a piece of paper on it. He said proudly, "No matter what secrets the weapon refining grandmaster wants to hide from others, they can all be seen through by my keen eyes!"

Tang Ru complained to him: "How dare you! If Xiaoxiao hadn't told you, if Xiaoxiao hadn't drawn the line, what would you have discovered?"

Tong Nuonuo puffed up his cheeks, and said with half his momentum weakened: "Then, then I should also contribute half. Do you know how much effort I put in to reconstruct this map?"

Chen Xiao pulled him to sit down, "Okay, I know you've worked hard, sit down and eat. If you didn't come down, we were going to bring it to you later. The chef has changed the dishes, try this minced fish roll, it's very fresh."

Tong Nuonuo was extremely hungry. While stuffing food into his mouth, he said, "I originally thought that this atlas was hiding some secret manual for making magic tools, but it turned out to be a map! I'm sure that a map hidden in such a covert way must be a legacy for tool refiners! Only those tool refiners with weird tempers would pass on their knowledge in such a strange way."
