?An Yu took a few deep breaths, calmed down his chaotic mood, slowly raised his arm, pointed to the bronze ware in front of him and said, "There is nothing in these elixir furnaces! It's empty!"

"Hey! Junior brother, are you confused? Or guess?" Le Feng didn't believe what An Yu said. He flashed, jumped to the edge of the open-covered bronze ware, and took a torch to illuminate it. It was indeed empty inside. Le Feng was a little unwilling to give up, and looked at several bronze ware that had just moved the lid, and the inside was also empty. He was shocked, and suddenly appeared cunning on his face. He quickly grabbed An Yu's side, kneaded the latter's body, and said, "Tsk tsk! Chengfeng, is this Chengfeng? It's not a clone! The body wouldn't have been hidden around the copper cauldron, right?" Le Feng said, looking at the bronze ware with thunderous eyes, but even if An Yu himself was really invisible there, he would definitely not see it.

"It's the smell!" An Yu stopped Le Feng from touching him and said, "I concluded that the elixir furnace was empty, based on the smell! If there was really a corpse inside, you can imagine the burnt and pungent smell!" An Yu said, frowned slightly, and immediately appeared in his mind that the terrifying and unpleasant smell and the shocking burnt were as if they were in front of him, vividly in his mind! Subconsciously, An Yu clenched his fists tightly, and the justice in his heart made him intolerable to such a tragic evil deed!

Hearing An Yu's explanation, not only Le Feng sniffed and sniffed around him hard, but Jingbei Nu, Li Yuduan and others also looked at each other, walked to the opened bronze ware, stroked his nose, and focused on sensing whether there was any odor. Sure enough, after everyone investigated, they did not find any abnormality. However, Zhu Wei, who had the strongest perception, hugged his arms, stared at the hands of the Fenglei Sect disciple who was opening the bronze ware lid, and looked at the hands of the Fenglei Sect disciple who was opening the lid, with a look of confusion on his face.

"Zhu Wei, what's wrong? Do you smell anything abnormal?" Jing Beinu asked. Zhu Wei frowned, wanted to speak but stopped, and finally shook his head gently and said, "Strange! Although I don't know anything abnormal, I always feel that something is changing... Well... it seems that there is no change!" He glanced around and said, "Strange!"

An Yu couldn't find any flaws and said, "These alchemy furnaces must have been dealt with by those people!" He circled several alchemy furnaces, and finally his eyes fell on the lid placed on the ground. His expression moved. He thought to himself, "When people checked the alchemy furnace, they took off the lid and put it aside, only checked the space in the abdomen of the alchemy furnace, but ignored the lid... And when those people dealt with the traces, would they only clean the alchemy furnace and ignore the lid?"

Walking to a copper cover, An Yu carefully checked the surface of the copper cover, but no abnormalities were found. Then, he gathered energy and lifted his strength, slowly turned the copper cover over, and turned the copper cover upwards toward the side in the belly of the furnace.

"Hey? This is..." An Yu was stunned and found an unprecedented mechanism or structure inside the copper cover. There was a small round convex surface in the middle, connected with the inner part of the copper cover through eight radial copper radiations, and there were several octagonal rings in the middle, connecting the eight copper radiations together. Overall, it looked like a spider web that was pulled up in the middle. An Yu's heart flashed with light, and his eyes looked at the ground next to him, and said in surprise: "This is actually a 'human oil' flow channel on the ground, so it is... why is it the flow channel?"

An Yu's eyes turned to the copper ware, imagining the copper cover back to the top. At this moment, the raised spider web-shaped copper radiation turned around and was a setting with a high surrounding and sunken middle, which was connected to the edge of the copper cover. If any liquid condensed on the copper cover, it would definitely slowly gather at the circular concave surface in the middle along the spider web-like copper radiation!

"This is a collector!" An Yu suddenly said in surprise. When others heard it, they immediately came over, but no one knew what the collector was. Because the collector was a tool that can only be used in the field of alchemists and doctors. It is mainly used for purifying or extracting certain liquid materials, but it was not really used. An Yu had been a calculator for several months, but he had only seen it in a few pharmacological books, but he had never used it.

An Yu thought that since this is a collector, it must be a liquid that is extremely concentrated, and extremely concentrated means it is extremely difficult to remove! As long as a slight residue is left, it will be easily discovered. An Yu took out the pure white cotton cloth used when making medicine from the Hunyuan dish, walked around his index finger, and then he wiped it hard in the middle of the collector.

"Lefeng! Borrow a torch for use!" An Yu sent the cotton cloth to the light of the torch. After a closer look, the originally white cotton cloth was covered with a light black. Lefeng said, "This is not smoked ashes, right?" An Yu didn't know what this was, so he naturally leaned towards the ashes that the other party said. However, as a alchemist, his habits still prompted him to put the cotton cloth on the tip of his nose and sniff it gently!

An Yu's face was stunned, and a slightly familiar faint fragrance came into his nose, making him feel refreshed and from head to toe, he felt refreshed and refreshed. This feeling was like all the cells in his body were awakened, emitting endless vitality, and the heart of the Yuanli in the dantian seemed to be running faster. What surprised An Yu even more was that over the past period of time, his cultivation had been stuck in the bottleneck of 73 powers, and he had advanced naturally in this relaxation. An Yu finally reached the level of 74 powers in the early stage of the three meridians!

However, An Yu had no time to experience the excitement of promotion and the comfort of his body, because he suddenly recalled a detail. When he opened a elixir furnace in the "Man Oil Refining Workshop" in the water village, a crystal black bead as small as a bean was stuck on the cover of the elixir furnace. The faint fragrance emitted by the beads and the feeling it gave An Yu was as mysterious as before!

The only difference is that although the black fragrance substance at this moment is very small, it has a greater effect than the size of beans in Shuizhai. An Yu, from the professional viewpoint of an alchemist, believes that the concentration of these cotton cloth is higher, or more pure! If this is considered, if those mysterious people really refine this fragrance black substance, then their refining technology level has improved greatly! Of course, these are just one of the many ideas popped up in An Yu's mind like lightning, and are not worthy of being told by outsiders.

"Ah?" Le Feng suddenly felt surprised and said in confusion: "Chengfeng? Where is the black and gray on the cotton cloth? Have you sucked it in?" An Yu then realized that the cotton cloth around his fingertips was white, as if it had never been stained with anything, spotless! An Yu's face flashed with a look of astonishment. After a moment of silence, he quickly jumped to the front of another copper cover, turned it over, and wiped it on the collector with a cotton cloth. Sure enough, the white cotton cloth turned gray and black again.

"Lefeng, smell it, what does it smell!" An Yu thought that if he could benefit from it, Lefeng, who had been stuck in the bottleneck for a long time, would also benefit from the breakthrough. However, Lefeng didn't think much about it. He took the cotton cloth and gently put it under his nose, took a breath, closed his eyes, as if he was intoxicated. After a moment, he opened his eyes. An Yu hurriedly asked, "How is it? Lefeng? What changes are there?"

Le Feng glanced at An Yu who was a little strange and asked, "Is there any change?" He handed the cotton cloth back to An Yu and said, "My suction is not as strong as you, so I can't suck it away!" An Yu took it and saw that the gray and black marks on the cotton cloth were still there, and there was not a small appearance.

"Didn't you smell anything?" An Yu asked anxiously. Le Feng frowned and said, "...uh... if you want to talk about the smell, it seems to be a little...the fragrance of flowers? I'm not sure!" An Yu was suspicious and said, "The fragrance of flowers?" As he said, he put the cotton cloth under his nose and sucked it gently, and a soft fragrance immediately filled his whole body, giving him a sense of floating in ecstasy! What made An Yu puzzled was that the gray and black marks on the cotton cloth disappeared again, completely disappeared.

"Hey! Chengfeng, you're not playing tricks, right?" Le Feng glanced at An Yu disdainfully, as if he had seen through the latter's tricks. An Yu looked at the white cotton cloth on his fingertips, and recalled the time when he was in the water village, the mysterious black bead disappeared inexplicably after touching his fingers, and no trace was left behind! Now it seems that the two have the same nature and are indeed the same substance. However, what An Yu was very puzzled was that he could absorb that black substance, but Le Feng could not do it at all! Even the mysterious fragrance it emitted seemed that only he could smell it.

In order to confirm whether the others were like him or Tonglei Feng, An Yu used cotton cloth to apply some black substance from the third collector, and tested it for Jingbei Nu, He Yuyao, and even Mu Yang and other Fenglei Sect disciples. The result surprised him! Among these dozens, only An Yu himself could absorb that black substance, and that absorption was passive, as if his body had a strong attraction to black substance. Among the others, only Zhu Wei, who was the most sensitive to perception, could smell a little fragrance from the black substance of the cotton cloth. His feeling was only a faint refreshing, without the absorption visible to the naked eye, and there was no terrifying change like An Yu that even the level of cultivation level increased!

"You two, open the remaining two copper cauldron lids!" Mu Yang ordered. The two Fenglei Sect disciples took the order and immediately took action. The others were exploring the magic of black matter. They did not pay attention. Suddenly, Zhu Wei's eyes sterned, as if something incredible happened. At the same time, An Yu seemed to feel something, and looked at the two Fenglei Sect disciples who opened the copper lid.

"You feel it too?" Zhu Wei asked. Everyone didn't know what it said, so they could only nodded, saying, "It seems that there is an abnormal energy fluctuation! However, I'm not sure where it came from!" Zhu Wei's expression condensed and said, "Just as the copper cover is opened!"

"When the copper cover is opened?" An Yu's head flashed with an electric light, as if he had grabbed something. He murmured: "Everything here has been processed... has been processed... the alchemy furnace is turned on... abnormal energy fluctuations... Could it be..." At this time, the two disciples of the Fenglei Sect had touched their hands on the cover of the last bronze ware in the middle, and were about to open it with all their strength!

"Did those people also set traps?" An Yu's expression suddenly changed drastically, and he exclaimed at the same time as Zhu Wei: "Don't open..." But it was too late! Before they could finish their words, the copper cover and the bronze utensils had already separated!

In an instant, a strong golden light shot out from the gap, accompanied by a terrifying energy fluctuation that suffocated everyone. Driven by the bronze ware in the center, the eleven bronze ware around each sprayed a golden light column upwards! The energy pressure increased by hundreds of times in an instant, causing everyone to stagnate their energy and their bodies to be unable to move!

And the twelve bronze ware, including the copper cover left beside it, suddenly turned into golden powder under the dazzling golden light, spreading in all directions like fog!

Everyone could not move at all, and could not even blink. They could only watch the strange phenomena in the cave space like a statue and were powerless! The "golden mist" spread quickly evenly in the space. Then, it seemed to be attracted, and wrapped around all the moving human bodies for no reason! Just like a iron fan encountered a magnet, not to mention being unable to move, even if everyone has recovered their ability to move, there is no possibility of dodging!

In an instant, the golden mist dissipated, and more than a dozen golden human statues were added in the cave space. Under the reflection of the surrounding torches, they looked extremely hideous and terrifying!

All this happened between lightning and fire, as if golden light flashed by, and instantly switched to a scene.

...

The smoke is covered with mountains and mountains! Green trees shake the wind, flowers wash the rain! Under the dark sky, the green mountains are wet everywhere, but the greenness is fresher and the fragrance is clearer. What a paradise of fairyland!

However, under this weather environment, it makes people unable to distinguish the direction or even the time!

Deep in the cloud roots, two blurred figures appeared faintly. They walked very slowly, appearing and disappearing in the fog. After a long time, they walked around a huge rock and reappeared again. They had a hat on their heads, black veils hanging on their faces, and were wearing dark blue robes printed with sun, moon and stars. At first glance, they looked quite mysterious and mysterious! Their outfit was originally incompatible with the surrounding green mountains, green trees and white fog, but from a distance, they seemed to be integrated with everything around them!

"This mountain! This rain! This fog! This weather!" The mysterious man walking on the left said sadly: "It's so wet all over. It's so uncomfortable! That guy Wuwang actually arranged the two of us here. Is this avenge of private revenge?" But the mysterious man on the right just left and didn't speak, which made the other party quite bored and stopped talking.
