In a quiet room in the instrument room, Lu Yi was looking at a small brown tripod floating in the air in front of him with a sad face. This small tripod is the third-order mid-grade instrument tripod "Dead Wood Ding" that Lu Yi exchanged for the sect's contribution when he first came to Yaoshan. Because Lu Yi's cultivation is limited, he can only control the primary fire medium, so in the past, Lu Yi's refining tools were all refining some first- and second-order low-level magic weapons, even if he failed, that bit of material would not be distressing to Lu Yi. This time, it was still a rudimentary instrument room, and the fire medium in the room could only reach the top level of the third order, and the materials that could be refined could not be higher than the third order. In the past, Lu Yi also tried to refine third-order magic weapons, but the success rate was not too high, two or three out of ten, and they were all third-order lower-grade magic weapons, that day, Lu Yi was full of spirits and said a big thing, he wanted to refine a third-order high-grade magic weapon for Li Daniu, but when he entered the instrument room, he found that Xuanjin black iron ore was not so easy to refine.

Lu Yi has been in the instrument room for three days, and in three days, Lu Yi only purified a few pieces of ordinary black iron ore that he received at the beginning, and obtained a small black iron embryo, and Lu Yi has been purifying the Xuanjin black iron ore since yesterday, and has continued to burn it with a fire medium for ten hours, and it has just shown signs of softening, and he has no spiritual strength and has to stop working. This Li Da Niu is really lucky, he actually let him encounter a piece of ore with so much Xuanjin content, the grade of this ore is infinitely close to the third-order upper grade, and his own instrument is the third-order middle grade, so it is naturally difficult to refine.

Lu Yi's mind moved, the topaz gourd appeared in front of him, the topaz gourd is a fifth-order magic weapon, with Lu Yi's current spiritual power, he can exert the strength of the fourth-order magic weapon, if he uses the flame of the topaz gourd to refine the Xuanjin black iron, it should be very easy, but once the fire is not well controlled, the Xuanjin black iron will turn into nothing, do you want to take a risk? After careful consideration, Lu Yi thought of a good way, that is, to refine a few third-order magic weapons for himself to try the power of the gourd. The lowest level that Lu Yi is using now is also a fourth-order magic weapon, if you use a magic weapon to participate in the selection competition, first, it is too ostentatious, you take the fourth-order magic weapon to participate in the selection competition rewarded as a third-order high-grade magic weapon, and it is strange not to be scolded to death; second, the power is too great, unable to reflect your own skills, and more importantly, the competition expressly prohibits the use of any items above the fourth order. Therefore, the last time Lu Yi did it with Li Shuquan, Lu Yi always dealt with it empty-handed. Think about the upcoming trials, there must be a lot of masters, and then empty-handed against the enemy will inevitably be a bit too big, in case you miss, lose the opportunity to go out and play, it will be worth the loss. After thinking about it, Lu Yi decided to use the topaz gourd to refine a few magic weapons for himself first, and familiarize himself with it, after all, he has a lot of materials in his hands, and he is not afraid of wasting it, and then refining the Xuanjin black iron when he is proficient in his skills, so as to ensure that nothing goes wrong. Such a loser's plan, that is, Lu Dagongzi can do it, and others must know that he squandered materials like this, and he must not be distressed to death.

As soon as his mind moved, a bunch of materials appeared in front of Lu Yi, such as mountain bear paws, three-tailed magpie beaks, magpie feathers, land turtle shells, iron pear wood, and pseudo-gold and copper。。。。。。 Lu Yi made a move, and a fist-sized pseudo-gold and copper fell into his hand, this pseudo-gold and copper is a third-order high-grade material, which looks like gold, but in fact it is a copper ore, with a soft texture, but the toughness is very good, even if it is elongated into a filament, it is not easy to break, and it is suitable for making nets or whips. Lu Yi weighed the copper mine in his hand, and said to himself: "Let's take you to practice first." ”

After that, Lu Yi threw the copper ore into the air, used mana to fix it in the air, pinched the trick with one hand, urged the topaz gourd to suck it, and sucked the ore into the gourd. Lu Yi probed his spiritual power into the gourd, silently used the magic trick, urged the flames in the gourd, and cautiously approached the copper block, slowly, the flame wrapped the copper block little by little, and the copper block began to melt. "It's done!" Lu Yi was overjoyed, but the next moment, tragedy happened. Lu Yi was overjoyed in his heart, bringing about an instantaneous fluctuation of spiritual power, and the fire instantly swelled, swallowing up the entire copper block at once, and there was not even a bit of slag left. "Damn!" Lu Yi scolded his mother angrily. Look at the time, it's time to be on duty tomorrow, let's get here today, go back to sum up the experience in the past few days, and by the way, look through the relevant classics in the magic building to see if you can find a better way. Thinking of this, Lu Yi tidied up his things, got up and left the quiet room.

Time flies, and in a blink of an eye, ten days of duty life is over, and early in the morning, Lu Yi hurriedly came down from the peak and plunged into a rudimentary quiet room in the instrument room. Take out a piece of pseudo-gold and copper ore from the storage bracelet, suck it into the topaz gourd, concentrate on controlling the flame in the gourd to wrap and burn the ore little by little, half an hour has passed, a palm-sized pseudo-gold and copper ore has become a golden object the size of an egg, this is the purified pure pseudo-gold and copper, with a move of his mind, Lu Yi took it out of the gourd, the pure pseudo-gold and copper were suspended in the air, exuding a golden light, and a layer of fine beads of sweat appeared on Lu Yi's forehead, which shows that the consumption of spiritual power is still very large. Lu Yi took a second-order elixir "Huishen Pill" and meditated with his eyes closed, and began to recover his mental power, and after two hours, his spiritual power was completely restored, Lu Yi took out another piece of ore and began to try. After two days of hard work, Lu Yi has refined seven pieces of third-order high-grade materials, and there are four pieces that can be thoroughly purified, Lu Yi deeply realized that spiritual power plays a vital role in the control of fire, and several of the larger ones are all due to poor mental power, but Lu Yi's accurate use of spiritual power has improved a lot, especially when purifying the seventh piece of ore, the original watermelon-sized ore was carefully controlled by Lu Yi, and the purification work was basically completed, but it was only in the last moment that the mental power was not good, and there was a slight fluctuation, which led to the flames getting out of control and failing。

Lu Yi took a "Huishen Pill", sat in the quiet room with his eyes closed, thinking about the gains and losses of these ore refining, this sitting is a day, when Lu Yi opened his eyes again, Lu Yi felt unusually full of energy, and his spiritual power also increased slightly, and his mind moved, Xuanjin black iron ore appeared in front of Lu Yi, and Lu Yi planned to purify it.
