This warehouse is much larger than the warehouse of the grocery store, and it houses some well-built weapons and piles of forging materials.

Chen Shuang's eyes looked around carefully, and found that there were a lot of first-order spiritual materials, stepped forward, and stood still in front of a pile of ore glowing with a faint blue light. This is the Xuaniron Crystal Ore, which is only produced at the junction of the Xuaniron Mine and the Spirit Stone Mine, although it is common, but it cannot be used by non-refiners, because it is mixed with spirit stones, which cannot be dissolved with mortal fire, and if it is forcibly created, it will destroy the structure of the material itself.

Chen Shuang had the law of the fire system, he could lightly smelt this material, and it was enough to use the Xuaniron crystal ore to build a first-order Dan furnace. After taking two slightly larger pieces of ore, which weighed about seventy or eighty catties, Chen Shuang said to Niu Er: "Brother Niu, I'll just use these two, how many gold coins do you need?"

"Are you sure you want this kind of Xuaniron Crystal? Even I can't melt this, can you use it to build a Dan Furnace?" Niu Er saw that Chen Shuangxuan was actually a Xuaniron Crystal Ore, and his face was full of disbelief.

"The pharmacist taught me a small secret method that can increase the power of the flame, and I should be able to use it to build a Dan furnace. Chen Shuang explained.

"That's okay, as long as you can use it, forget about the gold coins, just think of it as me investing in your future Dan Dao in advance, and when you really become a Dan Master, I hope to bring my brother and me along." Niu Er heard Chen Shuang say that it was a secret method, and he didn't ask any more.

"Then thank you Brother Niu, don't worry, as long as I become a Danshi, I will definitely not forget Brother Niu, after all, I haven't come to your house to eat before, haven't I?" Chen Shuang didn't have a relationship with Niu Er.

The two took the ore to the casting room, and Niu Er didn't plan to watch Chen Shuang do it, they both said that they would use secret methods, and he didn't want Chen Shuang to be embarrassed.

After Chen Shuang waited for Niu Er to leave, he put the ore into the crucible on the casting table, which was directly dug out with meteorite from outside the sky, and had no other ability, that is, high temperature resistance.

Since his strength was not enough to shape the Dan furnace with spiritual power, Chen Shuang could only use the clay to pinch out a mold.

After making these preparations, Chen Shuang came to the crucible, put his hands under the pot, and released the spiritual power in his body from the palm of his hand, and at the same time operated the law of the fire system to transform the spiritual power into spiritual fire.

The moment the spiritual fire appeared, the crucible began to turn slightly red, and a wave of heat rushed to his face, although the flame could not hurt himself, but the change in temperature was not something that he could ignore in his current realm.

Drops of sweat appeared on Chen Shuang's forehead, and at this time, the dark iron crystal ore also began to change, the faint blue light became brighter, and then, the blue light turned into red light, which was the ore slowly melting.

As time passed little by little, about half an hour later, the two ores began to melt into sap, and there were some blue crystals that rose and fell in the sap, which were spirit stones that had not yet been completely melted.

Chen Shuang took out a hand and released the spiritual fire into the pot from above, doing his best to calcinate the impurities in the iron juice. At this time, the spirit stones in the pot also began to slowly dissolve into the dark iron juice, and slowly the spiritual energy began to float out of the crucible. After another pillar of incense, the aura emanating from the pot became even richer, and the original material of most of the pot was now only one-third, and at the same time, some impurities floating on it were all burned, Chen Shuang knew that the time had come.

Both hands extinguished the spiritual fire at the same time, picked up the crucible with a tong, and carefully poured it into the mold, and after the mold was filled, there was still a ball of material about the size of two fists left, so Chen Shuang quickly found the mold that Niu Er usually used to build weapons, took out a dagger mold from it, and poured the remaining Xuaniron crystal juice into it.

After it solidified a little, he took the Dan furnace and dagger out of the mold, and urged the law of solidity to make handprints on them.

The entire nine handprints were all played, Chen Shuang felt that there was not much spiritual power left in his body, and he couldn't take care of the dagger at this time, he could only transform the remaining spiritual power into spiritual fire again, and calcinate it against the Dan furnace that had already taken shape, he wanted to take advantage of the fact that the Dan furnace had not cooled down, and calcined the impurities from the mold again, otherwise it would affect the effect of alchemy.

As the last trace of spiritual power was squeezed out, the impurities on the Dan furnace were finally cleared.

Use a clamp to put the Dan furnace and the dagger that has not been completely cooled into the coolant that Niu Er usually uses, which is a specially formulated liquid that can slightly improve the quality of some finished products.

"~~~~~~~~~~!" a stream of water vapor rose from the cooling pool, and after a while, Chen Shuang took out the dagger and the Dan furnace from the cooling pool, looking at the dagger and the Dan furnace glowing with blue light, he felt an indescribable sense of accomplishment in his heart.

At this time, Niu Er pushed the door and walked in, obviously, he had been waiting outside the door until he heard the sound of quenching.

"This is, the construction has been successful, why is there an extra dagger?" Niu Er asked, looking at the two things placed on the casting table.

"There are still some materials left to build the Dan furnace, so I made a weapon, and Brother Niu helped me see how the quality was. Chen Shuang handed the dagger to Niu Er.

Niu Er took the dagger, played a few times casually, and then took out a piece of animal skin, the dagger stabbed violently, "whoosh", there was a small hole in the animal skin, and the dagger just stabbed down a knife tip. Niu Er took a closer look and found that the dagger did not strike. Then he used his spiritual power to urge the dagger to stab at the hide, this time the dagger went directly into the hilt.

Niu Er was a little surprised, and took a long knife he made himself, and cut it at the dagger, "clanging", the dagger was fine, but the long knife was broken.

"Brother Chen, how did you do this, this dagger can already be regarded as a first-order low-grade spiritual weapon, could it be that the pharmacist senior also taught you to refine the weapon?" Niu Er asked in surprise.

Like elixirs, spiritual artifacts are divided into nine levels, but each level is divided into lower grade, middle grade, upper grade, and best grade.

"He didn't teach me how to refine the weapon, I think it's because of the material, this Xuantie spirit crystal is a first-order spiritual material, and it can be made into a first-order spiritual weapon after smelting, which is also normal, in fact, the key problem in refining the spiritual weapon is still in the flame, without a strong flame, even the material can't be smelted, how can I refine the weapon. ”

Chen Shuang was also surprised when he looked at the dagger, and at the same time he also had more expectations for the Dan furnace in his hand. He knew very well that the grade of this Dan furnace was definitely above the dagger, after all, the Dan furnace had one more refining process than the latter.

Niu Er didn't know much about the Dan furnace, and he didn't look at the Dan furnace in Chen's hands, but he kept playing with the dagger in his hand, obviously he liked this dagger very much.

Seeing this, Chen Shuang spoke: "If Brother Niu likes it, this dagger will be given to you, and it will be regarded as compensation for the material, after all, the first-order spirit ore is also worth a lot." ”

Hearing this, Niu Er hurriedly excused himself: "No, no, no, that spirit mine is also a chicken rib for me, I can't use it myself, it's useless to put it, this dagger is different, the value of the spirit weapon is more than ten times that of the spirit mine, and this is the first weapon you built yourself, how can I ask for it!" After speaking, he returned the dagger to Chen Shuang.

"That's okay, anyway, you still have materials here, and I'll help Brother Niu refine a favorite weapon another day." Chen Shuang thought about it and took back the dagger, which was right, after all, this was his first weapon, although it was not the best, but it was quite commemorative.

"Okay, I'll just thank Brother Chen in advance. Niu Er's face was happy.

Chen Shuang didn't stay any longer and chatted with Niu Er for a few more words, then put the dagger into his waist and returned to his small courtyard with the Dan furnace in his arms.

When he returned to his Dan room, he looked at the kitchen utensils inside and shook his head, it seemed that he wanted to get a decent Dan room for his own use.

Standing in the courtyard, looking at the few houses in the courtyard, Chen Shuang finally decided to vacate the house where the old shopkeeper used to live and use it as a Dan room.

took out some sundries in the house, as well as some clothes that the old shopkeeper used to wear, and saw things and people, Chen Shuang's eyes couldn't help but turn red. He took out the jar of wine and came to a corner of the courtyard, where the ashes of the old shopkeeper were buried.

This is the edge of the 100,000 mountains, Chen Shuang also thought about burying the old shopkeeper in a place with good feng shui, but he was afraid that the old shopkeeper would be disturbed by wild beasts, so he could only be buried in his own yard, so that he could also be a companion.

A bowl of liquor was poured in front of the old shopkeeper's grave.

"Old man, you left too early, if you can survive for a few more days, I will definitely be able to find a way to cure you, but why can't you wait!" After speaking, a mouthful of strong wine was poured into his mouth, and tears couldn't stop pouring out.

"You say, why doesn't this god have long eyes, let such a good person pass away so early, but don't worry, Xiaoshuang I have grown up now, I can also cultivate, and I have adventures, I will definitely bring your share back to life, you watch it well in the sky, I must be a person!" Chen Shuang drank all the remaining wine in the jar, reached out and wiped his mouth, and then got up and continued to clean up the house.

I worked until the evening, and finally cleaned up the house, and threw away some useless things. Only a jade pendant that the old shopkeeper had been carrying with him before his death was left, and Chen Shuang brought it on his body, which can be regarded as a thought.

Looking at the empty room, Chen Shuang had to get a good night's sleep first, recover his physical strength, and refining the Dan Furnace could consume all his physical strength and spiritual power.

After taking a seven-yuan pill, Chen Shuang sat cross-legged on the bed, and did not deliberately guide, he had no exercises, so he could only let the spiritual power transformed by the pill flow in his physical strength, and finally returned to the dantian, passively recovering.

After digesting a pill, he felt that the spiritual power of his physical strength had recovered less than half, and Chen Shuang was a little surprised.

Another pill was thrown into his mouth, this time Chen Shuang carefully experienced the flow of spiritual power, and found that some of the spiritual power slowly infiltrated into the body, and then he understood what was going on.

It turned out that when he was refining the weapon, the spiritual power in his body was also squeezed out, and now it is slowly replenishing.

After four pills in a row, I finally felt that my physical strength and spiritual power had completely recovered.

Chen Shuang undressed and lying down and sleeping is the best way to recover his energy at present.
