In the middle of the night, the sky over the burning town was bleak, and the dark clouds were thick, and in the dense clouds, there was a faint roar of thunder.

At the beginning of spring, it is the thunderstorm season of the burning town, although this warm town is like spring all year round, there is no ice or snow all year round, but there is rain to make this town not so dry.

Click......

In the clouds of the sky, thunder flashed, the heavens and the earth lit up, and then there was a roaring thunder.

At this time, Qin Mo was in the room, refining a strange thing.

In the center of the room, there is a half-human-high iron tripod, and a flame is burning under the tripod, boiling the metal-like liquid in the tripod.

Crackle, crackle......

In the iron tripod, the metal-like liquid continued to concentrate, gradually flowing out a trace of glass-like color, exuding wisps of strange aura.

"Okay, it's almost successful!"

On the side, Qin Mo looked at the concentration of the liquid, his face was happy, and he took out a black [Iron Sand Iron] and poured it into the Iron Ding. Suddenly, the liquid in the tripod churned more violently, and the luster of the wisps of glass radiated out, blooming with a moving color.

This liquid in the iron tripod is a strange thing that Qin Mo has tried to refine in the past month.

In the refining basis of the first chapter of "Tiangong Kaiwu", this kind of [Qi Gathering Glass Liquid] is the simplest one, and it is also the cheapest one for refining raw materials.

However, after a month's time, Qin Mo realized that even the simplest of these strange things was quite difficult to refine. Beside Qin Mo, there were more than a dozen clay pots, which contained similar liquids, but they were unevenly colored, and they were obviously failed works.

In a moment, a wisp of cyan flame suddenly rose on the surface of the liquid in the iron tripod, and the liquid condensed and formed, the color was like glass, clear and transparent, and it was extremely delicate and beautiful.

"The refining of [Qi Gathering Glass Liquid] finally succeeded in making a bottle. Qin Mo breathed a sigh of relief.

Taking out a bottle and carefully holding the liquid in the iron ding, Qin Mo wiped the sweat from his forehead and smiled bitterly, he didn't expect that the simplest kind of strange thing refining would be so difficult.

As mentioned in the Fundamentals of Instrument Refining, the tools and raw materials required for the refining of [Qi Gathering Glass Liquid] are very simple.

The tools only need iron dings and mortal fire, and the materials are mortal-level low-level materials such as [Iron Sand Branding], Qin Mo originally thought that since it was the simplest kind of strange thing, it must not be difficult to refine. He began to try refining, and by the way, he practiced and became familiar with the basic techniques of alchemy.

Who knew that it took a month and dozens of failures before and after successfully refining a bottle.

However, thinking of the magical effect of the [Qi Gathering Glass Liquid], Qin Mo felt that a month's hard work was still quite worth it.

[Qi Gathering Glass Liquid], smearing this liquid on the array can increase the power of the formation by one order. Of course, it is limited to mortal-level and spirit-level formations, and Xuan-level formations are invalid.

You must know that every time the level of the formation is raised, its power is increased by one order compared to the level of martial arts, which is much more powerful. In particular, if the [Qi Gathering Liquid Liquid] is smeared on a mortal-level upper-level formation, it can increase the power of the formation to the level of a lower-level spiritual level.

The gap between mortal-level and spirit-level formations is much larger than the gap between mortal-level items and spirit-level items.

"It's a pity that it took a month to refine such a small bottle. Originally, I was planning to refine a full tripod to improve the formation level around the ancestral house. It's so whimsical. Qin Mo shook his head helplessly.

Around the courtyard of the Qin family, there is a mortal-level upper-level formation, which was arranged by the ancestor Qin Qishuo at the beginning, called the [Four Gate Bayan Formation].

In the manuscript of the ancestor, Qin Qishuo mentioned that when he arranged this large courtyard array, he had considered using [Qi Gathering Glass Liquid] to smear the formation device and raise this formation to the level of the lower level of the spirit level.

However, Qin Qishuo's talent was quite ordinary, both in terms of formation and in the refining of strange things. He had never succeeded in refining this [Qi Gathering Glass Liquid] once, and as for the arrangement of the [Four Gate Rock Formation], it was not complete, and he only comprehended half of the essence of this formation.

"Forget it, use this bottle of [Qi Gathering Glass Liquid] to strengthen the weak points of the formation around the ancestral house one by one. Then, it was time for me to go. ”

Immediately, Qin Mo put away the bottle of strange things, packed up all kinds of items, put them in the gray treasure bag, looked around, made sure that there were no omissions, and quietly left the room.

Tonight, he was ready to leave without saying goodbye and set off for the deep path in the Yin of Wanren Mountain.

Bang......

In the night sky, another flash of lightning swept up, thunder rolled in, and a downpour followed, and the entire burning town was shrouded in a curtain of rain.

......

Meanwhile.

Qin's house, deep in the backyard.

In front of the library pavilion, in the big tree, there were bursts of painful screams, as if someone was suppressing the severe pain and wailing in a low voice.

In the dense rain curtain, under the tree, Elder Gao stood there, letting the rain wet his clothes, but his face was anxious, and his expression was full of worry and sorrow.

"Old Ling, how are you now?" Elder Gao shouted urgently.

At this time, there was a low roar from the big tree: "Old Gao, what are you doing here? After a while, a spring thunder will blow down, affecting you, and there are no bones left, do you want to die with me?"

"You guy, do you want to be killed by the spring thunder so much?" Elder Gao couldn't help but scold angrily, suddenly remembered something, and shouted: "It's better to go to the library pavilion and hide, it is the strongest place in the Qin family's courtyard array, maybe you can avoid this catastrophe." ”

"Escape this catastrophe, Lao Gao, why do you want to deceive yourself? Do you want the Qin Family Library Pavilion to be destroyed with me?" In the big tree, Ling Protector sighed, "Between heaven and earth, the power of thunder is the most terrifying! If you want to defend against thunder and lightning, you need at least a spirit-level formation, and the Qin Family's Courtyard Guardian Formation is only a mortal-level formation, how can it resist the spring thunder bombardment. ”

"Alas, Lao Gao, you and I have been playing against each other for decades, and we can be called confidants. Now that I'm about to die, with you as a confidant to say goodbye, I can be regarded as dying without regrets......"

I didn't finish the sentence.

With a click, a flash of lightning swept through the dark clouds, and a trace of electric light seemed to be attracted, falling from the sky, falling on the branches of the great tree, and then dissolving into it.

Immediately, a terrible wail sounded in the big tree, and although it was extremely suppressed, it could be felt that Ling Protector was suffering greatly.

The next moment, the trees swayed, and the surrounding water waves changed, and a figure loomed, then became clear, and with a pop, fell into the rain.

This is an old man with a withered face, his hair is pale green, and he wears a cloak like leaves, and his appearance is extremely strange. A flash of lightning swirled around him, causing him to tremble and curl up in pain.

Seeing this, Elder Gao wanted to step forward: "Old Ling, you ......"

"Don't come here, Lao Gao, do you really want to die with me?" the old man roared.

Immediately, Ling Protector looked up at the dark rain curtain, let the rain splash on his face, and laughed miserably: "I have been tortured by this half-useless [Phantom Blue Cloth] for decades, I thought that it would be difficult to regain my human form in this life, but I didn't expect that before I died, I would change back into a human body, and it could be regarded as a wish fulfilled." ”

Bang......

In the night sky, there was a sudden thunderclap, as if in response to Elder Ling's words.

"Lao Gao, you and my friend, watch quietly. When I'm dead, burying my bones is a friendship. Ling Protector said in a deep voice.

Not far away, Elder Gao clenched his fists and lamented in a low voice, seeing that his best friend's life was in danger, but he was powerless, it was really an unbearable torment.

At this moment, in the dark night, slight footsteps sounded, and the figure of a young man appeared in the backyard, it was Qin Mo.

"It's ......"

Standing in the path, Qin Mo couldn't help but be stunned when he saw Elder Gao and the figure of a strange old man, at this time, a lightning bolt crossed the night sky, illuminating the figure of the old man, and also allowing Qin Mo to see the old man's appearance clearly.

On the rain-soaked ground, the old man was dressed in a strange emerald green robe, his face was withered, and there was a faint trace of electricity on the surface of his body......

Seeing this scene, Qin Mo was shocked in his heart, this scene was so familiar, he had often encountered it, in his previous life, those appraisers and martial arts powerhouses often held half-abandoned Xuan-level treasures in their hands, and when they underwent the baptism of thunder and channeled again, this was the scene.

The fundamental difference between Xuan-level items and spirit-level items is that the interior of Xuan-level items has a trace of spirituality. It is this trace of spirituality that makes Xuan-level items have all kinds of incredible functions, so Xuan-level items are also called Xuanbao.

Once a Xuan-level item is destroyed and loses this inner spirituality, it is a half-waste, the grade falls, and the function is lost.

However, the reason why Xuan-level items are called Xuanbao is that Xuanbao also has the ability to repair itself. After a period of time, the half-waste Xuan-level items can spontaneously absorb the thunder, and after baptism, they will once again glow with the brilliance of the Xuanbao.

Such a process is - Xuanbao Psychic!
