Under the hospitality of the first seat of the Chengyang Palace, Luo Yu could only be in a hurry, because no matter what method he used, he could not mobilize the invisible heavenly fire, in fact, he couldn't find it at all.

This strange invisible flame does not stay in the dantian and coexist with spiritual power like ordinary fires, and can be mobilized for the master's use at any time, but there is no trace, as if it has disappeared out of thin air.

A variety of methods were tested to no avail, and the first seat of the Chengyang Hall was also confused, this was the first time he was helpless against the alien flames, and he even had no clue. He couldn't help but wonder, could it be that just like when it appeared out of thin air in the void of heaven, this kind of flame would disappear once it had finished its effect?

In desperation, he had no choice but to take out another flame that Luoyu had tried just now and let him suck it into his body.

This lucky spark once again regained Luoyu's divine thoughts, and excitedly burst into large clusters of sparks, and fled towards Luoyu's body!

But as soon as it came into contact with Luoyu's body, the invisible flame appeared out of thin air again, forcefully squeezing out the new flame. Not only that, but the invisible heavenly fire was like a living thing, chasing and killing the new fire, burning it to the point of fleeing in a hurry!

Retracting the pitiful fire that was so badly wounded, dejected, and almost burned to translucent, the two of them stared at each other with big eyes.

After a while, Luo Yu asked carefully: "Is this invisible heavenly fire related to the wheel of life?" At first, I thought it was headed for my sea of consciousness, but in fact, it was the wheel of life at the center of the eyebrows that actively absorbed it, and when it spewed out again, it also came from the seven wheel energy vortexes. ”

Although the first seat of the Chengyang Hall was also familiar with the cultivation method of the wheel of life, he had never heard that the wheel of life could still contain fire. The only thing he could do was to hand over a lot of fire control experience and notes left by his predecessors to Luoyu, and let him study them slowly, but he didn't know how much of a role these things could play for him.

After some false alarm and confusion, Luo Yu finally stands in the place where he is about to play a coolie that should be valuable.

In a stone room surrounded by a lot of tools, materials, and fragments of semi-finished formations, the first seat of the Chengyang Hall beckoned Luoyu to a stone platform placed in the center of the room.

The stone platform was painted with intricate rune formations, holding up a looming green light shield and enveloping a worn tortoiseshell round shield.

The head of the Chengyang Hall pointed to the tortoiseshell round shield on the stone platform, and said: "This is an artifact with a damaged spirit, which was severely damaged in a long battle, although we have used many methods to try to make up for it, it is still weakening day by day, and time is running out. Because I saw you, I thought of a new way, so I asked you to come and try it and see if I could bring it back to life. ”

Luo Yu couldn't believe his eyes, this tattered tortoiseshell round shield was actually an artifact?

He didn't expect that he, a coolie, would still shoulder the important duty and mission of repairing the artifact?

Mu Ran nodded, and he heard the head of the Chengyang Hall continue to speak: "The formation patterns painted on the stone platform can gather spiritual energy, play a role in nourishing the artifact, and prolong the life of the artifact, but these can only delay the loss of vitality, and cannot be fundamentally repaired. Your task is to help me draw another set of formations, condense the aura of the thunder attribute, and convert it into energy that stimulates vitality, and see how it works.

"Most of the thunder attribute auras are violent and difficult to control. It is difficult for ordinary people to grasp the nuances of it, and most of what can be mobilized is the power that destroys vitality, not the power that stimulates vitality. Your master said that you have a strong control, so I want you to help me control the formation.

"I wanted to teach you how to refine a new formation, but you don't have a flame to use, and you can't smelt materials to engrave the formation, so you can only watch me do it. ”

Luoyu nodded and took the formation blueprint.

This was the first time he had seen such a complex design, and this array could not even be engraved on the base of the same array, and could only be engraved on different material plates according to functionalization, and then spliced together to form a complete array.

The first seat of the Chengyang Hall beckoned, and some ore materials of various colors flew in front of him from the corner, and his hands were quickly covered with a layer of blue on the outside but orange-red on the inside, and with just a few light wipes, this pile of materials was melted into a lava-like liquid, and then it was evenly divided into twelve pieces, each forming a figure, which was the base plate of the pedestal that would carry different formations.

Stretching out his hand and pointing at the drawing, the first thing he had to engrave was the outermost edge of the formation diagram that absorbed the transformation aura.

The most basic spirit gathering array Luo Yu has long been learning, he can see a few similarities from the picture, these should be derived from the most basic spirit gathering array changes, but the formation patterns on this drawing are dense, layer by layer, it should be to engrave the most formation patterns in the smallest space, in order to achieve the maximum spirit gathering effect.

The first seat of the Chengyang Hall closed his eyes slightly, and a few sparks appeared on the bottom plate of the three arrays in front of him at the same time, each jumping and spinning at an extremely fast speed, pulling out a series of gorgeous flame tails. Everywhere he passed, the blue-gray base plate was smelted out of the dark golden formation, and in just a few breaths, the three formations were ready.

Luo Yu was dizzying, and he was really shocked by the astonishing speed of this carved formation. It wasn't until the first seat of the Chengyang Hall pointed to another formation diagram model, saying that he was going to start doing this next, that Luo Yu came back to his senses.

Looking at the new formation, Luo Yu suddenly had a more familiar feeling.

Many of the lines in this formation were similar to the formations he had seen in the cave of the Lianshan Ancient Realm, according to his understanding, this formation should also have the effect of condensing and transforming the aura of the thunder attribute, but it was not as complex as the formation in the cave. Probably because the formation pattern in the cave not only has the effect of gathering and transforming the aura of heaven and earth, but also raises the Purple Pole Heavenly Heart Flower, and also has the function of attacking and guarding, I think the difference between the two is mainly in these aspects.

Now that there is a formation in front of him, Luo Yu naturally will not let it go, and immediately compares the spirit array he saw that day and asks about the differences.

Unexpectedly, the first seat of the Chengyang Palace, which has always regarded all kinds of spirit arrays as the greatest pursuit and persistence in his life, heard it with his eyes lit up, and his face was a little fanatical.

Luoyu suddenly felt bad, but he couldn't stop if he wanted to, because the first seat of Chengyang Hall had already thrown away half of the things in his hand and threw him a ring of questions, so that he had to answer if he wanted to, and he had to answer if he didn't want to, and he couldn't even pretend to have amnesia.

After a series of questions, the first seat of Chengyang Hall had completely grasped the initiative, probably because he felt that it was too inefficient to ask like this, so he simply took out a pen and paper and urged Luoyu to copy all the parts he could remember, and then study them carefully.

What's even more terrifying is that Luoyu occasionally forgets a part, but it is not a problem for him at all, either using a few clues to forcibly evoke Luoyu's memory, or simply filling it in completely.

Although Luo Yu's brain was drained and he only drew a sub-array diagram, the first seat of the Chengyang Hall was not disappointed, but stared at the array diagram excitedly, and praised again and again: "The creation of heaven and earth is really beyond the reach of human beings! If you can fully comprehend the mystery of this, then you will be invincible in the thunder system spell." ”

Luo Yu was secretly glad in his heart, fortunately, the first seat of the Chengyang Hall was just a madman who was obsessed with this way, but he was not a bad person, and his attention was completely on the formation diagram from beginning to end, without the slightest intention of delving into his secrets. This discovery made him relax a little, so he took his speculation about the effect of the pattern one by one to verify, and many vague guesses were explained in detail, and he felt that he had gained a lot.
