When he approached, Huang Yuchen clearly saw that a corner of the hall was filled with various crystals, roughly estimated to be less than a few hundred pieces, and they were piled up randomly. Next to the crystals was a seat that was the same as in the hall, and there was also an exquisite instrument on the seat. It was obviously used to infusate crystals here, but for some reason there was only one seat here, and it seemed that no one had used it for a long time.

"Maybe it's the elder's own seat." Huang Yuchen scratched his head and didn't think much about it.

From time to time, a low "buzzing" sound came from the alchemy furnace on the side. Looking in through the translucent window, the object suspended in the alchemy furnace was surrounded by a blue flame and was slowly rolling in the alchemy furnace, making a tremor from time to time. This low sound was what was heard from the things in the alchemy furnace.

Liu Xing'an and Qi Zhengye were bored and turned the entire hall and studied the alchemy furnace in the middle for a while, but now they have obviously lost interest.

There are also a large number of blank crystals piled up in the other corner, and there is only one exit in the entire hall. Judging from the appearance here, no one should come normally.

Huang Yuchen couldn't figure out where the Chihong Sect got such a large number of crystal stones. You should know that he only saw one in Cangmang Mountain, but he had also seen a large number of spirit-gathering stones used in Tianqing City. This is quite strange. It seems that this thing is not a rare item in the sect, but he has never seen it in the Eastern Palace.

If the army has a large number of such spirit-gathering crystals and is equipped in an elite force, then such an army will be arrogant. In the face of absolute force, any tactics and strategies are useless.

Huang Yuchen picked up a crystal stone and put it in his hand. The crystal stone was not as big as that, and it was only half the size of his palm. It was much smaller than the Linzhen crystal stone seen in Cangmangshan in my memory, so the total amount of Dou Qi it could store was naturally much smaller.

"Yuchen, start working quickly." Qi Zhengye walked around the hall twice and found that the things inside were really unkind and it was a strange place, which made him feel like he didn't want to continue here.

"Senior Brother Qi is anxious?" Huang Yuchen grabbed the crystal stone in his hand and looked at Qi Zhengye. Usually, Qi Zhengye and Liu Xing'an have always given him a feeling of being out of the world. He doesn't take anything to heart, but today he can clearly feel that they are a little anxious.

"It doesn't feel good." Qi Zhengye looked at Huang Yuchen, and the expression on his face was quite relaxed, but he obviously felt uncomfortable.

"Yuchen, hurry up and do it. After making enough money, let's go quickly. This is not a place to stay for a long time." Liu Xing'an also walked over, frowned faintly, and his face was a little inappropriate.

Huang Yuchen's heart sank and he hurriedly asked, "What's wrong?"

"I can't say it, it feels something is wrong." Liu Xing'an whispered: "The flow of natural forces here is obviously different from the outside world, and it is probably related to this alchemy furnace." As he said that, Liu Xing'an pointed to the alchemy furnace next to him and said: "The natural forces flow faintly into the alchemy furnace. The longer they stay here, the clearer the feeling will be. I haven't found anything wrong yet. You should act quickly and we will leave as soon as possible."

When Huang Yuchen heard Liu Xing'an's words, he also frowned. He immediately closed his eyes and felt the changes in the flow of natural forces around him. As expected, the natural forces were slowly gathering into the alchemy furnace, but the speed of this gathering was very slow and could not be easily noticed.

Generally, there are two types of natural forces gathering. One is that someone is on the verge of breakthrough. In this process, natural forces will quickly gather to this person, and this situation is easy to perceive. The second is the source gathering array. The principle of the source gathering array is to form an area with a spell seal, and then use the spell seal to simulate the human body absorbing natural forces, so as to accelerate the flow of natural forces and achieve the effect of gathering energy.

The current situation is obviously not any of these two types. Without any external force interference, the natural force flows in the space at a peaceful and slow speed, and it rarely converges to a point. Huang Yuchen has carefully checked the alchemy furnace and found no traces of the source gathering array. The formation at the bottom of the alchemy furnace is used to decompose Dou Qi and refine energy, and it is not the arrangement of the source gathering array.

He opened his eyes and felt something was wrong. Judging from the layout of the hall and the dust on the seats beside him, it was obvious that no one came to this place often. Perhaps the people from the Chihong Sect knew about the situation in the alchemy room and did not come on purpose.

Huang Yuchen frowned and said softly: "Two senior brothers, please help me move this table out and get more crystals by the way. I'll move outside and try not to be affected by this place."

"Okay." Qi Liu and the others nodded, and without saying a word, they stepped forward and started moving things.

Huang Yuchen had done something like pouring crystal stones before. In this process, he needed to concentrate. If he did such a thing in a place where the power of nature was obviously gathering, the fighting spirit in his body would likely deviate. Before he could figure out the whole story, leaving here is the best choice.

Soon, Qi Zhengye and Liu Xing'an placed the table and the exquisite instruments on it in the yard, and went back to get a lot of crystal stones. Huang Yuchen followed him out and felt the surrounding environment. The gathering here was much lighter than in the hall, and it was almost impossible to detect it.

"It's here." Huang Yuchen said softly, then picked up a crystal stone and slowly called the Dou Qi in his body, wanting to try whether he could directly pour the Dou Qi into it. At that time, in Cangmang Mountain, the Linzhen Crystal stone could directly pour the Dou Qi into it, which was very convenient to use.

He inspires a little Dou Qi and slowly approaches the crystal in his hand, but Huang Yuchen is surprised to find that his Dou Qi actually bypasses the crystal and wraps the stone outside, without a trace of Dou Qi seeping in. In this regard, Huang Yuchen feels a little strange. It seems that the Linzhen crystal is indeed more advanced than this crystal. No wonder he needs to use this kind of instrument that looks a bit complicated.

After no attempt, Huang Yuchen sat at the table and began to carefully study the instrument in front of him. The instrument looked very delicate, and translucent pipes formed the main body of the instrument. In the middle of the pipe, a simple stone could be seen, with several array talismans carved on it, which were never seen by Huang Yuchen before.

There are thousands of changes in array talismans. After being able to use array roots skillfully, there are countless ways to carve them on them. If you look carefully at these array talismans, you will find that these array talismans are all carved by the Dui character array root. In other words, the array savage who makes these stones is not as capable as Huang Yuchen.

The pipe has two ends, one end is hanging, and the end is a flat stone slab, which should be used to place the palms to pour the bucket air into the other end, and the other end is obviously used to place crystal stones.

This thing looks exquisite and complex, especially the stones that carved the formation in the middle. Huang Yuchen had never seen this kind of application of the formation talisman before.

"What, can you use it?" Qi Zhengye saw Huang Yuchen stunned for a long time without moving, and asked involuntarily.

"It should look very simple." Huang Yuchen looked up and chuckled, "I just want to know the principle of his work. I have never seen these things before."

"This kind of crystal stone is not uncommon in the sect world." Liu Xing'an said on the side: "It's just that because it's difficult to inject Dou Qi, this thing is not used in large quantities. Each sect has a different infusion method, but the effect is not satisfactory, so this thing is a bit useless and is not used by ordinary sects."

"The Chihong Sect actually has a method to break through the barrier of this kind of crystal stone. When mass-produced, this kind of thing is extremely powerful and cholera is also extremely great." Qi Zhengye frowned and looked at the crystal stones piled up around Huang Yuchen, and was in a clear mood.

Huang Yuchen looked at the crystal stone in his hand, then the instrument in front of him, and the corners of his mouth moved, but he didn't say anything.

There were many things he could think of, and these things made him involuntarily think of the things of the Qitian Empire. The ability shown by Chihong Sect is no less than that of the Eastern Prince's Mansion. There is one thing he is very strange. Why did Chihong Sect use such powerful force to keep it in this mountain? They must be planning something, but what are they doing specifically?

He sighed softly. He knew that no matter how much he thought, it would be useless. At present, he could only do what he had in his hands first and liberate himself. According to Nangong Wei's calculation method, a piece of ice and fire attribute crystal can be exchanged for 500 taels, and he would have to make 60 yuan in seven days to pay off the debt he owed. If he included the money he owed Lin Yiyi, he would have to do one more yuan.

Nangong Wei once said that if you make five pieces in one night, it seems that this thing is not as simple as you imagine.

No longer thinking about those messy thoughts, Huang Yuchen placed the crystal stones in the instrument, and then mobilized the fighting spirit, allowing the fire-attribute fighting spirit to fill the palm of his palm, slowly approaching the hanging stone slab.

The fiery red Dou Qi touched the stone slab and immediately began to spread, into the instrument's pipe, and then passed through the center of the stone with the talisman carved. After the Dou Qi entered the stone, the spell seals on the stone lit up one by one. It was not until the circle of talismans on the stone lit up that the Dou Qi slowly flowed out from the other end, and then slowly injected into the crystal stone in front of him.

This process is not slow, but the fighting energy that can enter the instrument is limited, that is, the speed of injecting crystal stones is not fast.

Huang Yuchen could clearly see that the crystal in front of him was lit up little by little by little by little by little. At this speed, a crystal was completely filled, and it would probably take half an hour.

Huang Yuchen felt helpless about this. While releasing his fighting spirit, he looked up at Qi Liu and the others and said, "At this speed, I don't think it's faster."

Qi Zhengye and Liu Xing'an stood beside Huang Yuchen with frowns, watching the crystals slowly fill up. The speed is indeed no different from that of a snail crawling.

"There is no other way, so take it slowly." Qi Zhengye said: "Anyway, there is nothing wrong with this. At this speed, it is absolutely fine to earn 30,000 taels in seven days."

"Don't think about the others. When you finish this matter, you will consider the use of this crystal." Liu Xingan said quietly, "Things are definitely not as simple as it seems."

"I'm a little hungry. Have you brought dry food?" Huang Yuchen looked at the two of them, grinned and asked.

"Where is there any dry food?" Qi Zhengye frowned and said, "I ate so much at noon, and I'm hungry now?"

"I'm working." Huang Yuchen glared and said, "How can I make money if I don't give me food?"

"Okay, I'll buy it for you." Qi Zhengye sighed, then stretched out a hand at Huang Yuchen and said, "Get the money."

Huang Yuchen was stunned: "What's the money?"
