Chu Yan's face was happy, he succeeded, although the first-order mid-grade spirit weapon was still far from the second-order, but this proved that his guess was not wrong, the key to improving the quality of the spirit weapon was in the drawing of the spirit pattern.

After finding the reason, Chu Yan also realized a lot in his heart, he ran to Elder Jiu, and thanked him first: "Thank you Elder for mentioning it, the disciple is grateful." ”

"No need, you still have excellent understanding." Elder Wine took a sip of wine and smiled.

"Then thank you for the elder's advice, otherwise I may not be able to understand."

After Chu Yan smiled and thanked him, he ran into the library to rummage through the books on drawing spirit patterns, read them carefully, and when he had a small harvest, he continued to come to the refining room to conduct experiments.

In this way, dozens of days passed quickly, and Chu Yan's refining techniques had become more and more proficient, and after the main class of the day, he came to the refining room again to open the furnace and refine the weapons.

"Senior brother, you go to refining weapons again!" Seeing that Chu Yan went to the refining room again, he asked.

"Yes, do you want to be together?"

"Okay!" Bamboo pole smiled happily, he happened to want to see how much Chu Yan had improved for more than ten days, if he practiced a low-grade flying sword again, he could prostitute it for nothing.

When the two of them came to the refining room, Elder Jiu was already very familiar with Chu Yan, so he didn't need to say hello, he walked in directly.

Chu Yan is already familiar with the refining steps, raising the furnace, discharging materials, smelting, shaping, and forging the bamboo poles on the side in one go, and he is directly stunned.

Gather Spirits!

With Chu Yan's outline, a spiritual pattern slowly appeared on the sword blank, and then a trace of spiritual energy slowly flowed along the spiritual pattern until the spiritual pattern was completely lit up.

"The inferior spirit weapon is done!"

The bamboo pole clapped his hands happily in congratulations, but Chu Yan did not stop his movements, but continued to outline, and another spiritual pattern appeared and lit up.

"First-order medium grade! Senior brother, you are really amazing, in just ten days, you will be able to refine a medium-grade spiritual weapon. As he spoke, he suddenly Chu Yan continued to outline the spirit pattern, and this time he suddenly raised his heart to his throat, there is no other high-grade spirit weapon that is extremely difficult, and the entire instrument peak can be refined by one or two people, as for Chu Yan, he is definitely not among them, so forcibly raising the flying sword to the top grade will only end up shattering.

"Senior brother! You~"

A faint but dazzling light interrupted the bamboo pole's words.

Laugh at!

A burst of white smoke rose and the flying sword with three spirit patterns was completely forged, and Chu Yan stroked the sword body, still a little dissatisfied: "Alas, it's still a little bit worse." ”

"Still a little short?" Zhu Pole had mixed feelings in his heart, and he guessed with a strange expression: "Senior Brother Chu Yan, you didn't want to forge a second-order spirit weapon just now, did you?" ”

"Exactly! But it didn't work out, and it's a pity. ”

"Shhh Bamboo pole's eyes widened and he looked at Chu Yan: "Senior brother, are you still human?" "It's just a demon in front of him, it's only been less than a month since he entered the Instrument Peak, and he has already refined a high-grade spiritual weapon, but this is still the result of his dissatisfaction, what he wants to refine is a second-order spiritual weapon.

"Senior brother, what are these words? I'm not human, am I still a ghost? Chu Yan laughed.

"Senior brother, I'm a little confused, I'll go out and blow the wind!"

"Senior brother walks slowly."

Bidding farewell to the bamboo pole, Chu Yan stood in place and carefully looked at the high-grade flying sword that had just been baked, he injected the spiritual energy, and the flying sword immediately lit up with white light, but if you look closely, you can see that in the white light, there is a trace of yellow light that is extremely small.

"Why the hell is it so close?" Chu Yan didn't quite understand, this flying sword, he had reached perfection in drawing spirit patterns, but he had not been able to break through its grade to the second order, and he couldn't understand the mystery.

With puzzlement, Chu Yan went into the library pavilion again to find an agreement, but he didn't gain anything after wasting an afternoon's effort.

So the next morning, he stopped Hengcheng, who was leaving, after the morning class.

"Disciple, I've seen the elders."

Heng Cheng saw that it was Chu Yan, and immediately stroked his beard and smiled: "It turned out to be you, what problems did you encounter that couldn't be solved?" ”

"Elder, the disciple would like to ask a question about refining weapons, how can the elder refine a second-order spirit weapon, and what are the main points?"

"Second-order spirit weapon?" Heng Cheng raised his eyebrows slightly, and asked tentatively, "Haven't you already refined a first-order high-grade spiritual weapon?" ”

Chu Yan nodded in response: "Exactly, but the disciple really can't refine a second-order spirit weapon, so I have come to ask the elder for advice!" ”

"You~cough!" Heng Cheng suppressed his excitement with a dry cough, and said: "The second-order spirit weapon is extremely difficult to refine, and its key point is not only in the drawing of the spirit pattern, but also in the two very basic steps. ”

"What?"

"Summoning fire and smelting!"

"Calling for fire? Smelting? Chu Yan didn't quite understand, for him, these two steps were the easiest in the refining process, he had already succeeded in summoning the fire, and smelting was to wait for the furnace fire temperature to reach and then put in the spiritual materials and wait, what is the mystery of this?

"Did you know that there are three levels of spiritual fire?"

"I know!"

"That's it, the effect of the same spiritual material on different spiritual fire surfaces is completely different, the higher the grade of spiritual fire, the better the effect when smelting, the impurities in the spiritual material will be eliminated more, the molten iron will be blended faster, and the overflowing spiritual energy will also be further refined by high temperature, so the quality of the final refined spiritual weapon will also be greatly improved, so as to reach the second order." Heng Cheng answered Chu Yan's question in as much detail as possible.

Chu Yan frowned slightly: "Then how can the spiritual fire grade be improved?" "After all, the spiritual fire he summoned at the beginning was level one.

Heng Cheng touched his beard and said: "The way now is for you to improve your cultivation, after all, now you are only the second level of qi refining, and it is already good luck to be able to summon a first-level spiritual fire." ”

"Disciple understood!"

Chu Yan suddenly realized, his cultivation was indeed a little low, he had been busy cultivating the formation and refining weapons since a few days ago, and his realm had indeed not improved much, although the aura in his body was already relatively low compared to the fourth level of qi refining, but it was still a little lower after all.

Back in the cave mansion, Chu Yan immediately took out the only few medium-grade spirit stones and arranged a second-order spirit gathering array in the cave mansion.

As the formation operated, the aura that was so rich that it was substantial suddenly gathered beside Chu Yan, and he hurriedly sat down cross-legged, running the exercises to absorb the aura into his body.

I don't know how long it took, a muffled sound came from Chu Yan's body, and the whole person's aura became more powerful, and he broke through.

"Three layers of Qi training!" Chu Yan smiled, he looked up and found that it was already dusk the next day.

"Cultivation has no time, and that's true."

With a sigh of emotion, Chu Yan stretched out his palm and called the fire here, and with the urging of spiritual power, a wisp of light red flame showed his figure in Chu Yan's hand.

"Or is it level one? Wrong! Chu Yan took a closer look, the color of the first-level spiritual fire in his hand now was darker than the first-level spiritual fire he summoned last time, but it still hadn't reached the second-level standard.

"You have to work hard!"

Chu Yan realized that this was a little bit of cultivation, so he could only take out the lower-grade spirit stone he had just received, and arrange a second-order spirit gathering array, and fell into cultivation here.

Two days later, Chu Yan's breath, who was sitting cross-legged, climbed again, reaching the fourth level of qi training.

"The fourth layer of Qi training!"

Chu Yan smiled slightly, he was not too proud, the qi training period is the process of the monk absorbing the spiritual energy into the body, as long as the spiritual energy is enough, it can be broken through, so there is no bottleneck.

After calming down the aura in his body, Chu Yan stretched out his right hand and urged the aura to summon fire for the third time.

Laugh at! A wisp of dark red flame, dancing in his palm!

Dark red, second-level spiritual fire!
