"If it's a condensation of the three-grade purple spirit core, it's still a little too risky." Luo Yutian said lightly.

"The third-grade purple spirit core should be considered a leader, right?" Garlic said.

Luo Yutian looked at Garlic Bi, but said, "Senior brother, the grade of the spirit core should be raised a little higher. So, what Senior Brother wanted to condense at the beginning was the purple spirit core of the third grade, right? ”

Gong Changdao glanced at him, "You want to say that the purple spirit core is still not able to stabilize the energy fluctuations of Shen Aluminum?" Are you saying that you need a fourth-grade red spirit core? ”

Luo Yutian thought about it, flipped through the books on the table again, and then said, "Perhaps, it's a little higher."

"Do you mean the golden spirit core of the fifth grade?" Garlic swallowed the saliva in his mouth reluctantly.

"No way. How could the golden spirit core be condensed without cultivation above the seventh or eighth order? Moreover, after the golden spirit core, there is a sixth-grade white-gold spirit core, relatively speaking, it is already very difficult for the fourth-grade red spirit core to be able to control the energy fluctuations in it. Gong Changdao said.

Luo Yutian shook his head, but said, "The four-pint spirit core I mean is being raised a little higher, not the meaning of raising the four-grade spirit core to the five-grade spirit core."

Gong Changdao immediately gave Luo Yutian a violent shudder, "Stinky boy, what kind of dumb riddles are you playing?" ”

Luo Yutian said helplessly: "Teacher, you are wronged!" I mean refining the red spirit core to a purity of more than 80 percent. ”

Gong Changdao was silent for a few breaths, and was about to say something, but Garlic Bi opened his mouth and said, "This method is good, but the difficulty of refining purity is not something we can do. If you want to speed up the purity of refining the spirit core itself, it is more difficult than refining the purity of the metal. ”

Gong Changdao also agreed with Garlic's statement, "Yes, the spirit core is not as easy to condense and form as we imagined. The spirit core is equivalent to an energy core of the Dou Armor itself, and when condensing the spirit core, it must also resonate with the energy fluctuations of the Dou Armor itself to have a general success rate. ”

Hearing Gong Changdao say this, Luo Yutian thought back to it, the last time Luo Yutian condensed the purple spirit core, if it weren't for the help of Yaning and Dragon Qi, the terrifying Luo Yutian would definitely fail to condense the spirit core that time. The purple spirit core is so difficult to handle, let alone the red spirit core at the upper level?

"Hmm...... All in all, your idea is a bit whimsical. But, I have to say, your idea is good. These patching methods are difficult though. But once it's done, the power of the fighting armor must be extraordinary. Gong Changdao said with a smile.

"Teacher, senior brother. Am I clear? Luo Yutian put away the design drawing on the table and handed it back to Garlic.

Garlic took the design drawing, looked at Gong Changdao again, "Teacher, what do you say?" ”

"Of course it's passed." As soon as Gong Changdao finished speaking, Luo Yutian immediately smiled. But Gong Changdao's next sentence made Luo Yutian cry and laugh a little, "However, the task I gave you can't be wasted." ”

"I see, teacher." Luo Yutian bowed slightly.

"Okay, there's nothing wrong with it, so let's get busy." Gong Changdao got off the table and stepped aside to sit down.

Garlic Bi returned to his work desk with the design drawing, and after Luo Yutian cleaned up the things on the table, he began to further study and describe the two pieces of Xuanyin.

Garlic's condensation skills are more mature than Luo Yutian's, and his research is naturally different from Luo Yutian's, and the research that Gong Changdao gave him is about the design of the Horcrux Exterminator.

Luo Yutian used the Spirit Eye ability to assist his work very well. These two pieces of Xuanyin were all changed by Luo Yutian to their own origin energy, and after changing the origin energy, their metal grades became the level of spiritual alloy. After turning into spiritual alloys, Luo Yutian could feel that their own purity had correspondingly become higher. What's more, these two pieces of Xuanyin are spiritual alloys! Natural energy fluctuations will be relatively strong.

After determining the energy division of the two pieces of Xuanyin, Luo Yutian first used a pen to draw marks on the three different places of the two pieces of Xuanyin. After drawing the mark, it was easier for Luo Yu to compare the differences and similarities between the two pieces of Xuanyin.

At first, Luo Yutian would have thought that each of them would be different. But in fact, he guessed wrong, the two pieces of Xuanyin both belonged to the stage of spiritual alloys, and before Luo Yutian used Dou Zhuan Xing to almost suppress most of the magazines and activity on their bodies.

When Luo Yutian just came back to his senses, he saw a golden bolt shining into the room from the window, which was a scorching sunlight. When the light came in through the window, it silently fell on the two pieces of black silver on the table.

The color of the silver itself is pale yellow, and when it is illuminated by the sunlight outside, the pale yellow light of the metal itself gradually becomes a little brighter, and the light of the silver itself is more beautiful than the previous light.

But Luo Yutian quickly noticed their abnormality, and when they were illuminated by the sun, Luo Yutian obviously saw that the two pieces of metal themselves had different energy textures when they were illuminated by the light. These textures loomed on Xuanyin itself, and at this time, Luo Yutian thought, could it be that the light was not strong enough?

After realizing this, Luo Yutian released his own golden light to illuminate Xuanyin itself.

After irradiating it with strong light for a while, Luo Yutian observed it, and then came to the final result, Luo Yutian frowned, it turned out to be like this!

After finally getting the result, Luo Yutian immediately started to carve the description on the cowhide scroll.

But on the cowhide scroll, if you want to prepare to let others know the content, you naturally can't be sloppy. Luo Yutian described the degree of the metal, and even the melting point, etc., very carefully on the scroll. When Xuanyin was depicted on it, Luo Yutian's palms seemed to be constantly bursting with cold sweat. When he started, Luo Yutian could feel that his heart was about to pop out. When his hand and pen landed on the scroll at the same time, Luo Yutian barely breathed a sigh of relief.

When drawing a design, you have to be attentive, if you make a mistake, the whole design will be ruined.

Finally, Luo Yutian spent all his strength to finally complete the research of Xuanyin itself.

Luo Yutian suddenly lay on the table, and when he was studying Xuanyin, Luo Yutian was almost releasing his Spirit Eye ability and light element energy. After completing the drawings, there was a feeling of prostration.

It wasn't until Luo Yutian lay on the table that he felt a sense of relief.

"Done?"

Seeing Luo Yutian lying on the table regardless of his image, Gong Changdao took a few steps over to look at him, and with a glance, he saw the design that Luo Yutian had just completed on the table. Gong Changdao pulled his hand, and the design on the table instantly fell into his hand.

After taking it and looking at it a few times, Gong Changdao felt very satisfied.

"You've improved a lot." Gong Changdao put the blueprints back down.

"How does it feel?" Gong Changdao looked at Luo Yutian who was lying on the table again.

Luo Yutian straightened up suddenly, "It's okay." It's good to take a break. By the way, teacher, what time is it? ”

Gong Changdao said, "Look outside, it's already noon time to finish eating."

Luo Yutian was stunned, "Did it take me that long?" ”

"Huh. This is the first metal diagram you've ever designed, right? How does it feel? Bow asked him.

Luo Yutian replied: "What do you say? At first, I was a little worried that I wouldn't do it well. The differences between the two pieces of silver are almost immediately apparent, but it is precisely their similarities that are a little difficult to find. ”

Gong Changdao smiled, "If it weren't for the sunlight outside telling you, wouldn't you have been able to find it all along?" ”

"Possibly."

Gong Changdao continued, "Xuanyin is not the best existence among the many metals. But this metal's control over energy is relatively moderate, and it will not be as lacking in energy as deep aluminum, nor is it as powerful as the energy of the red essence. The energy of Xuanyin itself is relatively moderate, and it can also be said to be very balanced. ”

Luo Yutian bowed slightly, "Yes." The textures on their surfaces seem to outline different patterns, but in fact, their textures flow in the same way. Later, when I put pen to paper, I was still a little nervous. The palms of his hands were full of sweat. ”

Gong Changdao said, "Garlic is designing a Soul Slayer, and it will be completed in a while." Shall we wait for him to go to dinner together? ”

Luo Yutian bowed slightly.

Luo Yutian and Gong Changdao didn't wait for a long time, and five minutes after Luo Yutian completed the design drawing, Garlic was also completed.

Luo Yutian took a peek a few times in the past, and this design drawing of Garlic was much more complicated than his own.

"It's ......"

Garlic said: "This is the fifth-level Horcrux exterminator I designed, and now I have only completed the appearance, and there are still many aspects that have not yet been completed, and it may still take a little time."

Gong Changdao seemed to see Luo Yutian's eyes flashing with golden light.

"Want to learn?"

Luo Yutian nodded vigorously.

"When you reach the level of garlic, you can also learn the Horcrux Exterminator. It's just that you're still learning the basics. It may take some time. Gong Changdao said lightly, "Okay, if it drags on any longer, the time for dinner will be over, let's go eat something first." ”

Luo Yutian and Garlic bowed slightly.

To be continued!
