The way of refining tools is very simple, it is nothing more than the study of the properties of various material veins. Everything has its pulse, and the vein is made up of countless points of light and the channels between them. The monks discovered that it was these channels that determined the state of matter, and that by refining the channels or forcibly grafting channels of different materials, the matter could be large or small, and great power could be stimulated. From this, alchemy was born.

For a month, Qian Xue listened to Qiu Xin's explanation, and naturally understood the principle of refining tools very clearly, and secretly talked about the complexity of refining tools.

Qianxue said: "Even a simple branch has countless passages, how easy is it to find the passage you need from it?"

Qiu Xin said: "Which passages have which properties, there have been ancestors who have summarized them into a book, we just need to check the books, but many key passages or new discoveries are often tightly hidden by the refining masters, and they will not be revealed to others easily." ”

In fact, the refining weapon is also in a state of decay due to the great war a hundred years ago, and many genius monks have gradually given up relying on external objects, such as spiritual weapons and formations, and have turned to explore themselves, which is the mainstream of today's era.

And Qianxue and Qiu Xin, the two juniors, can be said to be newborn calves who are not afraid of tigers, and they really dare to put forward any ideas. No, Qianxue has only been learning refining for a month, so she came up with an idea that makes the refining apprentice laugh when he hears it:

"What would happen if a formation was engraved into the refining material?"

Sure enough, Qiu Xin also felt funny when he heard it, and said politely: "Generally, after the spirit weapon is formed, the formation is carved on the surface of the spirit weapon to attract the surrounding spiritual energy, if you carve the formation inside, not to mention that it is absolutely impossible, even if it is carved, what is the use?"

Qianxue didn't hear the last sentence and said, "It's impossible to say anything, but it's not necessarily." ”

Qiu Xin listened to Qianxue's guidance this month, and naturally understood some of the principles of the formation, and knew that the formation was all based on the traction of the five elements. At this time, after listening to Qianxue's crooked reasoning, he said angrily: "There is no aura circulating in the material, how can it be carved?"

"Why not? Aren't those colorful points of light aura?"

"Those points of light are motionless, how can they be aura?" Qiu Xin said this, his heart moved, what if he let those points of light move?

"How do you know if you don't try?"

So, the two began to toss the materials in different ways, trying to find a way to make the light point move. In this way, Qiu Ping was a little busier than before, looking at the thousands of materials in her hand, and sighed in her heart: What two losers!

After another month, the two finally explored a method, but they needed an extremely high temperature environment. Qiu Xin proposed: "There is a basement dedicated to refining weapons in the sect, where there is an extremely high temperature earth fire or you can try it, but you need a medium-grade spirit stone to enter it once." ”

Qian Xue naturally didn't pay attention to it, waved her big hand, and said, "Let's go and try this method if it doesn't work." ”

When they arrived at the place, the two of them randomly chose a stone room, set up a refining furnace, led the fire, and waited for the results. And with the introduction of the ground fire, the temperature in the stone room also rose, and Rao is Qiu Xin, as a seventh-layer Qi cultivation monk, still sweated.

On the other hand, Qianxue, but the fourth layer of Qi training, actually observed the changes in the material calmly, and did not sweat a penny.

Qiu Xin said strangely: "Don't you feel hot?"

"It's okay. Qianxue said casually, and after a while she remembered something, she added: "Aha, it's really hot here." ”

Qiu Xin was suspicious, but he didn't think much about it, and observed the changes in the materials like Qianxue. These materials are specially made by them in order to allow heat to enter the material along a specific channel, trying to excite the light points inside.

Within half an hour, they saw that the material had turned into slag, and a trace of aura slowly floated out of it! The two looked at each other and said in unison: "Impossible!"

They repeated the experiment again, and the result was still the same, as soon as the heat entered the material along the route they had set, the light points inside would move violently, and the material would collapse, and a trace of aura would be generated!

Both of them were dumbfounded, their original purpose was just to make the light points inside work, and then try to carve a formation inside, but now this result scared them at a loss!

Qiu Xin said: "You say, if we announce this result, will we be burned to death?"

Qian Xue said uncertainly: "No, there are many strange things in the immortal cultivation world." ”

"However, this is a complete reversal of the monk's understanding of cultivating immortals since ancient times!" Qiu Xin felt uneasy, and said, "Maybe we made a mistake in what steps?"

Qianxue naturally knew that there was a general consensus in the immortal cultivation world since ancient times: there was an immortal realm on this continent, and the powerful monks there would inject spiritual energy into this continent, and as long as the monks practiced diligently, they would one day be able to soar to the sky and live with the sky!

Because if there is no immortal realm, it seems difficult to explain the fact that the spiritual energy of this continent is inexhaustible, and the monks can indeed increase their lifespan by cultivating with spiritual energy.

However, the experiments of Qianxue and Akishin have shown that the aura has not existed since ancient times, and it is very likely that it was accidental! For example, after a lightning strike a tree, the heat happened to be transferred along that route, so the aura was generated.

The two didn't bother for long, and started a new round of experiments. Now that it has been proved that the light points inside the material are indeed aura, the next step is how to carve a formation into it and how to make the light points run stably.

They studied in the stone chamber for several days without any results, and Qiu Xin couldn't stand the sultry atmosphere here, so he proposed to go back to the grass hut to study a charter and then experiment.

Qianxue naturally agreed, so she stepped forward to take down the refining furnace and put it in the storage bag, and when she looked at Qiu Xin again, she found that she was staring at her with wide eyes.

"What's wrong?" Chiyuki didn't know.

"That refining furnace has been roasted by the earth fire for several days, how dare you take it with your bare hands?" said Qiu Xin.

"Ahh

"Oh, I forgot, you memory. Qiu Xin said, there were still some doubts in his heart.

Seeing this, Qianxue hurriedly said, "Let's go quickly, your sister should be angry." ”

Hearing Qianxue mention her sister, she was so frightened that she left that trace of doubt behind, hurriedly packed her things, and rushed to the ruthless peak with Qianxue.

Although the two flew back together, their thoughts were different. Qiu Xin was in a hurry while thinking about how to deal with her sister later, and when Qianxue thought about taking the refining furnace just now, the strings seemed to be a little faster, she seemed to have seized an opportunity, but she didn't figure out what it was for a while.

When she arrived at the foot of Ruthless Peak, Qianxue said to Qiu Xin: "You go back first, I'll go to Old Man Lin's trip." Qiu Xin dared to go back alone, and said busily: "I have also admired Uncle Lin's name for a long time, can I go to visit with you." ”

Qianxue has been going to Old Man Lin alone for the past few years, and there is no one to discuss when she encounters problems, but now she is very happy to see that Qiu Xin is willing to accompany her.

When the two of them saw Lin Shi, they were both taken aback. I saw that his face was pale, and a pair of cloudy old eyes stared directly at the abandoned array flag on the stone table.

After learning the formation method from Old Man Lin for a few years, Qian Xue knew that he was studying a seven-star array, and the idea was to divide the formation veins into seven parts and hide them in seven different spaces, each of which changed as much as possible according to the five elements and eight trigrams. Once the arrangement is successful, according to the old man's words, I can go sideways from now on, old man.

It's a pity that the seventh formation flag failed to succeed in any case.

Qianxue's formation has improved very quickly in recent years, and she can also understand the difficulty: there is no formation without a formation vein in the world, if the formation vein is divided into seven and distributed separately, then who will maintain these seven parts? There is only the formation of the formation vein, but in this way, the concept of the Seven Star Array seems absurd, because the formation of the formation is still the formation vein!

At this time, Qianxue saw Qiu Xin's appearance of wanting to speak and stopped, and said curiously: "Qiu Xin, what's wrong?"

When Qiu Xin asked, he said, "I see that the lines of these six array flags are like the six parts of a certain spiritual weapon, but only one part is missing to be considered complete. ”

As soon as these words came out, Qianxue was overjoyed and said, "Are you saying that you can map the seven-split formation vein into the spirit weapon, and use the spirit weapon to manipulate the seven-star array?"

"I don't know how to map, but I can refine a complete spiritual weapon that is consistent with the pattern of these six array flags. ”

The more the two talked, the happier they became, and discussed the principle of this idea over and over again. Old man Lin listened to the more and more they talked, and couldn't help but shout: "Two little ghosts, what are you talking nonsense here? ”

Qian Xue went through the experiments they had done in detail, and finally said, "It can be seen that it is not impossible to carve a formation inside the spirit weapon. ”

After listening to Qianxue's experiment, Old Man Lin turned the river and the sea in his heart, and looked at the slightly immature faces of the two, and sighed in his heart: Sure enough, it is the back waves of the Yangtze River that push the front waves, and the hero is a teenager.

He said, "Old man, I don't believe in these ridiculous things, if you really have the ability, you can make a seven-star spirit weapon." ”

Seeing that the old man had the intention to test their abilities, Qianxue and Qiu Xin did not flinch, and said in unison: "What's so difficult about this?"

Back at the top of the mountain, Qiu Xin couldn't help but be counted down by Qiu Ping again, so don't mention it.

As the saying goes, time is like an arrow, and if you are not careful, another year has passed. Since the agreement with Old Man Lin that day, Qianxue and Qiu Xin have divided their labor and cooperated, one person is responsible for refining weapons, and the other is responsible for familiarizing themselves with the principles of the Seven Star Array.

After a year of cooperation and exchanges, the level of the two has become more and more sophisticated, and they have finally refined the seven-star spirit weapon. And with the birth of the spirit weapon, Qian Xue also carved out the seventh array flag according to the structure of the spirit weapon.

Take it to Old Man Lin and try it, and it is really powerful. Qianxue was very familiar with the principle of the formation, and went to break through in person, but she was also trapped for more than ten days before breaking out of the formation.

At this point, Old Man Lin was convinced, and he knew that Qianxue's formation level had completely surpassed him.
