After Bai Yunfei returned to his residence, he didn't do anything else, he stayed in the house almost all day, holding the golden dagger in his hand, carefully recalling every detail of Kou Changkong's refining, remembering it deeply in his mind, and feeling it little by little.

The next day, it was still in the same spacious secret room.

“......”

"Yunfei, I have already told you some of the keys to the first step of melting, now, you can try it yourself and see how far you can go. After Kou Changkong explained to Bai Yunfei for a while, he said with a smile, then flipped his right hand, took out a fist-sized piece of black ore, and handed it to Bai Yunfei, "This is a piece of gold essence stone that is similar to the one I refined yesterday, you can melt it and take a look." ”

"Yes, Master. Bai Yunfei responded, took this piece of golden essence stone, pondered for a moment, then took a deep breath, his eyes condensed, and his soul power instantly gathered in his right hand, and a dazzling flame burned with a 'bang', wrapping the golden essence stone in it.

The flame held the ore and floated a few inches in his palm, and as the output soul power strengthened, the flame became more and more intense, and the golden essence stone in it began to gradually shrink at a speed visible to the naked eye, and all the impurities were incinerated and dissipated one by one, gradually precipitating the golden essence.

Kou Changkong nodded slightly in satisfaction, but after a while, he saw that Bai Yunfei had suddenly weakened the strength of the flames, and the stone that had been refined to only one-third of its original size had completely turned into a golden liquid, slowly rolling in the fire.

"It's not enough, Yunfei, continue refining. Kou Changkong's faint voice came, Bai Yunfei nodded slightly with a solemn expression, and re-strengthened his soul power, and the golden liquid began to shrink again.

After a while, Kou Changkong frowned slightly, and reminded: "It's too much! Yunfei, stop!"

"Ahh

Bai Yunfei was shocked in his heart, and hurriedly collected the fire yuan power, but it was too late, the golden liquid that originally emitted a brilliant golden light seemed to exceed the limit, and it suddenly burned in the flames, and in the blink of an eye, it turned into a few bits of black ash and landed in the palm of his hand.

"Master......" Bai Yunfei felt a moment of loss in his heart, and looked at Kou Changkong with shame.

"Hehe, don't worry, it's normal to not be able to grasp the timing at first. Kou Changkong shook his head slightly and comforted, "Experience can only be accumulated through countless failures, don't think that you can succeed at one time, then you won't be able to better understand the key." ”

With a wave of his empty hand, a half-human-high pile of concentrate appeared next to him, he casually picked up a piece of dark red ore and handed it to Bai Yunfei, and said, "Go on, I won't remind you this time, you slowly master the strength yourself." ”

"Yes, Master. ”

Bai Yunfei took the ore and began refining and melting again in earnest......

Fail.

Fail.

Fail......

After four or five hours, Bai Yunfei finally reluctantly finished extracting the essence of a fire ore.

Looking at the half-fist-sized red liquid wrapped in flames in his palm, Bai Yunfei raised his left hand and wiped a little sweat from his forehead, and his heart was excited.

Kou Changkong smiled and nodded, and said, "Well, that's good, then let's start the second step now, Yunfei, you try to integrate these three auxiliary materials......"

............

For a whole day, Bai Yunfei tried to complete every step little by little under the guidance of Kou Changkong, tried again and again, failed again and again, and used all kinds of raw material concentrates alone.

The concentrate that Bai Yunfei destroyed on this day alone was enough to make its leader go crazy if it was placed in a small sect or family in the outside world......

Until nightfall, Bai Yunfei still did not complete the second step of 'blending', and every time he was unable to grasp the strength of the fire element force when integrating the auxiliary materials, he either burned the materials or added the wrong amount.

"Bang!"

The flames dissipated, and a cloud of golden liquid within it collapsed into bits of molten iron and scattered on the ground with a slight 'sizzle' sound—and failed again.

"Whew, whew......" Bai Yunfei gasped heavily, his forehead was covered with sweat, the high concentration of energy throughout the day, and the continuous consumption of soul power, coupled with the blows that had been failing, had already made him a little unbearable.

"Alright, Yunfei, let's stop here today. ”

When Bai Yunfei wanted to reach out for the concentrate again, Kou Changkong's voice sounded beside him, he looked up at Kou Changkong and said, "Master, the disciple wants to try a few more times...... Maybe it'll be successful next time......"

Kou Changkong shook his head slightly: "Yunfei, you are in a bit of a hurry, your current state is not suitable for continuing refining, let's stop here today, you go back and think carefully, think calmly, and continue tomorrow." ”

Bai Yunfei was silent for a moment, looked at the concentrate next to him with some unwillingness, and said dejectedly: "Yes, Master, the disciple will go back......"

......

Back at his residence, Bai Yunfei, who had been tired all day, was not even in the mood to eat dinner, lying on the bed, looking at the roof in a daze.

"Refiner, refine...... It's so difficult! I can't even do the simplest refining......" Bai Yunfei sighed in his heart, this refining technique is really too difficult to practice, and in some places, the detailed control of fire element power, as well as the restrictions on the collection and release of soul power, are simply harsh to the point of outrageous, if it is converted into soul power point consumption, it is almost accurate to the level of half a bit of soul power......

After a moment of trance, Bai Yunfei reined in his mind and clenched his fists hard, the loss in his eyes gradually receded, becoming persistent and firm.

"It's just the first day, if you retreat now, then you really failed, Master is right, experience is to be summed up and accumulated in countless failures, as long as you work hard to accumulate experience, you will definitely be able to succeed!"

No longer distracted, Bai Yunfei closed his eyes and began to 'replay' every fragment of today in his mind little by little, where he didn't control it well when he failed, what it felt like when every little detail was successful, and the key points that Kou Changkong reminded him of, all of which surfaced in his mind and remembered them - over and over again, over and over again......

............

The next day, under the guidance of Kou Changkong, Bai Yunfei began to try again and again.

Fail, continue.

Fail, continue.

Fail, keep ......

Before he knew it, the whole day passed again, but he still hadn't completed the second step.

Day 3.

Day 4.

Day 5.

......

It wasn't until the tenth day that Bai Yunfei finally achieved the final key point of the third step of 'condensation'......

Staring closely at the three-inch-long knife in his hand, which had almost begun to shimmer with a metallic luster, Bai Yunfei secretly roared in his heart: "The last time it has changed, the strength of the fire refining is seventy percent of the previous one, give it to me...... Make it!"

"Bang!"

With a slight explosion, the flames turned into a wave of heat and dispersed, and a dark red knife fell into Bai Yunfei's hand.

"Great, Cheng ......" Bai Yunfei was overjoyed in his heart, but the joy had just risen, and he was immediately shattered by a faint 'click' sound, only to see a small crack on the three-inch knife gradually spread, and the next second, the knife shattered into several pieces in front of Bai Yunfei's eyes.

“......”

A strong sense of loss and unwillingness welled up in his heart, Bai Yunfei's right fist was clenched hard, and there was a 'click' sound, and the already broken knife was pinched into powder by him......
