A month later, Xu Chenglin finally walked out of the Hundred Refining Hall. His expression was extremely tired, and his face was very haggard, but there was a faint pride in his heart. This task of the Hundred Refining Hall has been taken over by countless people, but no one has ever been able to complete it. There is only one reason for this, and that is that the initial reward of this task is not high, but it takes a long time. Time spent is not proportional to the pay, so no one wants to complete this thankless task. Later, the reward for the task increased, but the amount of the task also increased, so the task was empty and rarely accepted. What a capable person can't, how to make him not proud. What made him even happier was that after completing the task, he not only got a lot of spirit stones, but also got a precious jade slip for passing on his merits.

Walking on the way back to the courtyard, Xu Chenglin was still thinking about the experience in the past month. After mastering the gold forging jade, Xu Chenglin finally knew the task he had to complete. The task is simple, just to recover the reusable material from the waste material. The content of the task is simple, but the amount of the task is terrifying. I don't know how long it has been accumulated, but all kinds of waste have been piled up into two hills.

No wonder the middle-aged senior brother emphasized that this task took too long and was a bit more rewarding than worth the loss. So that's the case, senior brother doesn't deceive me!"

Xu Chenglin smiled bitterly and shook his head helplessly.

After cleaning up his complicated feelings, Xu Chenglin began to sort and recycle these wastes.

Although there are many refining materials that need to be recycled, there are not many types, and most of them are refined iron, refined copper and some other ores. Through half a month of study, Xu Chenglin also has some understanding of refining materials. As far as the materials seen so far are mostly smelted metals. Legend has it that the metal materials that are really used to refine magic weapons must be quenched by the monk's natal true fire to remove impurities from the materials and concentrate their essence.

For example, iron essence is a material that can be used to refine the main body of magic weapons, and can also be used for ingredients. The refining of iron requires the monk to quench the refined iron with the natal true fire. The power of the monk's natal true fire is different, and the purity of the iron essence refined is also different. Ordinary iron ore is black, and after being refined into refined iron, it becomes pure white, and after being tempered by natal fire, pure white refined iron will show a blue substance with a little white light. In fact, there are impurities in each material, and the different impurity content will show different forms of the material. In these piles of materials, Xu Chenglin did not see the legendary materials that had been quenched by the natal true fire, and the most he saw were some ores of various colors with too much impurities. In fact, this is normal, the materials that have been tempered by the natal true fire are extremely precious, and it is strange to see them here.

Unlike alchemy, which has strict requirements for flames, refining tools are not too demanding on flames. The last thing that Bailian Hall lacks is the fire well, the red flames flowing inside the pitch-black well. This flame is actually not ordinary, it is the earth fire mined by Jiuhua Academy to communicate with the leylines. The earth fire was blessed by the spirit stone circle on the wall of the fire well, and the temperature of the flame became even hotter.

The same materials were selected by Xu Chenglin one by one, and they were put into the big tripod above the fire well. Unlike the tripod used for alchemy, the tripod used for smelting materials does not have a tripod cover. The lower part of the body is the same as the Dan furnace, leaving an outlet that communicates with the inside. The material melts into a liquid that can flow out of the outlet at the bottom of the body.

Under the blazing heat of the fire well flame, the metal and ore in the tripod gradually melted into liquid. The liquid metal goes through a series of flows and finally flows out of the outlet under the furnace. Seeing that there was liquid flowing out, Xu Chenglin hurriedly took a container to catch the liquid. When the liquid runs out and cools, the pieces of material are melted.

To recycle usable materials, smelting is the easiest means. For the recovery of some magic weapon fragments, more complex means are required. Most of the magic weapons are made of many different materials, plus formation prohibitions. Therefore, it is extremely difficult to break them down one by one. The magic weapon is meant to be strong and durable, so it is extremely difficult to disassemble the magic weapon fragments and refine a certain material.

To recover materials from magic weapon fragments, you must first break the formation prohibition on the fragments, and only in this way can the materials be returned to their original properties. Secondly, it is necessary to judge the material of the fragment and decide which method to use for smelting, and only when the right method is used can it be successfully smelted. Everything is easier said than done, and it is not easy to break the prohibition of the formation, and special techniques must be used to strip the prohibition from it. As for fragment refining, it's even more difficult. Different materials have different refining methods, and trying to refine the materials one by one is a time-consuming and laborious task.

In this way, he was busy day and day, and all kinds of available materials were quietly cleaned up by Xu Chenglin. Seeing that the task of recycling reusable materials was about to be completed, Xu Chenglin became more and more happy in his heart, and his subordinates moved faster and faster. Suddenly, a red glimmer came into his eyes. Looking at this red glimmer, Xu Chenglin inexplicably felt a strange feeling in his heart. In the past month, Xu Chenglin has seen a lot of various colors of light and various metals, and for some reason he is attracted by this almost invisible red light. As the old saying goes, there must be demons when things are abnormal. Xu Chenglin thought the same, so he dug out this red glimmer from the waste with three clicks and two clicks.

What shone faintly red, was an inconspicuous gray pendant. The pendant is in the shape of a gourd with several deep scratches on it, and the red silk thread of the tandem pendant is also damaged. I don't know why, such an inconspicuous thing, but Xu Chenglin looked at it and moved in his heart.

Tear off the red thread on the pendant three times and two times, and take the gray pendant in his hand and observe it carefully. This gray pendant is not gold or wood, it seems to be some kind of jade material, and from time to time a faint red light flashes from it. The carving on the surface of the pendant was somewhat unclear because of several deep scratches. If it weren't for the red light just now, it would definitely be disposed of as waste by Xu Chenglin.

"For some reason, looking at this thing always wants to leave it behind. This thing seems to have been damaged, and it is better for me to keep it myself. It shouldn't be too much to leave this thing privately. I repaired it again and made this thing a memento of my trip. ”

Xu Chenglin thought in his heart, and had already made up his mind to leave the small gourd pendant.

There is a kind of fate called eye edge, things are not very good, but they just look pleasing to the eye, this is the eye edge. The word fate is endless, and there is also a saying in the cultivation world. Some people say it's some kind of opportunity, some people say it's doomed, and some people say it's some possibility. But what exactly is fate, no one can say clearly, unpredictable and untouchable. Xu Chenglin's entry into the cultivation world is a kind of fate, coming to the Bailian Hall is a kind of fate, and being able to find a gourd pendant in a pile of miscellaneous items is also a kind of fate.

"Put this little gourd pendant in the storage bag first, and then dispose of it after completing the tasks of the Hundred Refining Hall. ”

Thinking like this, Xu Chenglin took out the storage bag. But then he was amazed, the white light of the storage bag swept over the pendant, and a faint red light blocked the white light back. The gourd pendant did not enter the storage bag, and still shimmered with a faint red light.

"It's strange that this thing can't be put in a storage bag?"

When he had doubts in his heart, Xu Chenglin also thought about it.

"What can't be put in a storage bag is nothing more than living things and some spiritual magic weapon. This gourd pendant is obviously not a living thing, could it be a spiritual magic weapon?"

Xu Chenglin looked at the small gourd pendant again, and his expression couldn't help but become solemn.

After looking at it for a long time, Xu Chenglin finally had no choice. He sighed and shook his head helplessly.

"The cultivation world is vast and boundless, and there are countless wonderful things, and my own knowledge is still too shallow! No matter what this gourd pendant is, what I got today is a kind of fate. ”

Thinking of this, Xu Chenglin calmly carried the gourd pendant in his arms.

After another seven days of sleeplessness, Xu Chenglin finally completed the remaining tasks. Mentally exhausted, he lay on the spot, and after a while he fell asleep. Maybe he was too tired, but he had several dreams. In the dream, Xu Chenglin dreamed of Baiyun Village, dreamed of his partner, dreamed of separation from his partner, and so on. A sharp pain came from the palm of his hand, and Xu Chenglin, who was asleep, was awakened by the pain, only to feel that there was something under his hand, so he subconsciously grabbed it.

Looking at the gourd pendant in his hand, Xu Chenglin smiled bitterly. Several scratches on the surface of the gourd, forming several barbs. The thing fell out of his bosom while he was asleep, and rolled right under his hands. Coincidentally, when Xu Chenglin turned over, these barbs cut through his palm. Looking at the wound on his palm, Xu Chenglin was a little speechless. It was obviously a small wound, but the blood couldn't stop flowing, and the small gourd pendant in his hand had been stained with a layer of blood. didn't pay too much attention to it, Xu Chenglin put the gourd pendant aside, found some water to clean up the wound.

After Xu Chenglin's wound was cleaned up, he remembered to take the pendant back. Reaching out to pick up the gourd pendant on the side, Xu Chenglin subconsciously wanted to wipe the blood stains on it. But to his surprise, there was no blood on the gourd pendant. Xu Chenglin thought that he hadn't woken up yet, so he rubbed his eyes vigorously.

"What's going on? Why is the blood on it gone?"

Xu Chenglin studied again, but the result was still nothing. Shaking his head helplessly, Xu Chenglin put the gourd pendant back into his arms. Stretching, Xu Chenglin walked out. What he didn't notice was that at the moment when he put the pendant in his arms, the gourd pendant suddenly lit up with a blood-red shimmer......

The hard work paid off, and the task of the Hundred Refining Hall was finally completed. After Xu Chenglin was inspected by the Hundred Refining Hall, he handed over the task and got the reward of the spirit stone, and at the same time took a jade slip of the Hundred Refining Hall to him, and walked on the road back to his residence.

"This time, it took less than two months to finally complete the task. It looks like you're losing, but you're actually getting more than you're paying. It's worth the delay. ”

Thinking so in his heart, Xu Chenglin's thoughts were after thinking again.

"Intentionally planting flowers does not bloom, and unintentionally planting willows and willows into shade. This alchemy technique seems to be the physical skill of his own cultivation path. It has taken a lot of time to refine the art of alchemy, but I believe that this time will create more value in the future. With the resources for cultivation and the cultivation skills available, the path of one's own cultivation can be regarded as the real beginning at this time. The fifth layer of the calcined body is about to be reached, so it is better to impact the fifth layer of the calcined body first, and then learn the method of refining. ”

already had a preliminary plan, so Xu Chenglin did not delay much. Looking at the blue sky and looking at the small courtyard not far from him, the pace under his feet couldn't help but speed up a little.
