Han Li's palm gently leaned forward, and the piece of marble in his palm slowly flew into the silver flames under the coercion of an immortal power.

The silver flame flickered a few times, enveloping the fist-sized white stone into it, slowly burning it.

However, as time passed, the white stone remained in its original state without the slightest change.

Han Li's face remained unchanged, and he pinched the magic technique with one hand, and the sound of chanting sounded in his mouth.

I saw that around the fire pit built by the black stone, there was suddenly a red light lit up in circles, and one by one the clumsy runes immediately appeared, jumping up and down.

After the silver flame in the pond lit up, it suddenly rose in a burst, and a layer of red light was enveloped outside the silver light, and the change in its firepower was not obvious, but there was an extra strange fluctuation in it.

With the emergence of this fluctuation, the Lang milling marble finally underwent a slight change.

After a burst of "sizzle" sounds, it finally melted in the silver flame wrap, and drops of milky white liquid like wax flowed out from it, which was slowly suspended in the flames.

A strong smell of sandalwood suddenly filled the entire secret room.

Seeing this, Han Li's outstretched palm suddenly retracted, and it had completely melted into a liquid-like Lang Milling Marble, which immediately flew out of the flames under the coercion of his immortal power.

His other hand reached over, and in the palm of his hand was already holding a black stone bottle with fiery red lines, and he inserted the liquid stone into it.

I saw that the milky white stone liquid flowed into the mouth of the bottle, and a circle of runes immediately lit up on the stone bottle, and the whole bottle became like a red-hot iron block, which was extremely hot.

Han Li had a layer of cyan light in his hand, and after sealing the mouth of the bottle, he placed it on the stone table beside him.

Then, with another wave of his palm, a piece of pure gold floated up and fell into the fire.

This time, instead of pinching the magic trick and urging the magic circle on the fire pit, he turned around and came to a stone platform more than half a foot high in the center of the cave, sat down cross-legged, and let the silver flame of the Essence Fire Bird smelt this piece of pure gold on its own.

Under the scorching flames, the petal-like lines on the surface of the vermilion pure gold lit up with red gold light, which contrasted with the silver firelight, but there was never the slightest appearance of melting away.

Han Li only glanced at it, then closed his eyes and breathed again, no longer looking.

Seven days and seven nights later.

In the midst of the fire, the silver flames were still burning, and the seemingly indestructible pure gold had completely turned red, like a piece of melting ice, on which drops of golden molten fell down.

Underneath it, there was a black stone bottle twice as large as before, which took in all the golden molten liquid bit by bit.

It took another full day for the piece of Pure Gold to be completely melted.

Han Li opened his eyes, stepped forward, put away the black stone bottle, and then took a piece of Pure Gold from the air and threw it into the fire......

Three months later.

In the cave, Han Li stood beside the fire pond, holding a beast skin book in one hand, frowning slightly and looking intently at it, gesturing back and forth in the void with the other.

On the stone platform beside him, thousands of yellow pages were stacked in a mess, each with a very strange and twisted pattern on it.

The more you cover the lower page, the thicker and more cluttered the lines are depicted, and the closer you get to the upper page, the more delicate and delicate the lines appear to be.

On the top four pages, the lines are already very fine, and they look like four large round flowers, which are very delicate.

In the upper left corner of the stone platform covered with paper, on the only empty space, there are more than a dozen gooseneck flasks of different sizes and materials, which contain all the spiritual liquid needed for sword refining.

During this time, in addition to refining various spiritual liquids, Han Li spent most of his time studying the gold melting sword techniques recorded in the Beast Skin Book, as well as practicing and drawing the magic circle runes recorded in the book on paper.

Although he had depicted it thousands of times, he was still not satisfied with the runes he could draw so far, and he always felt that the runes he had drawn were a little less meaningful, so he had not started refining them for a long time.

After a while, I heard only the sound of "pop".

Han Li closed the book, his eyes closed, as if he was in deep thought, he stood motionless, only the middle finger and index finger of his right hand were together, swiping slightly at his side, as if he was practicing drawing talismans in the void.

I don't know how long it took, as if he had a sudden flash of inspiration, his eyes opened, and he turned around and walked quickly to the fire.

I saw that his two fingers were together, and the golden light on the palm of his hand was bright, and the layers of golden scales were turned up, covering the two fingers.

He bent down, half-crouched beside the fire, and with two fingers down, he plunged straight into the rock on the left side of the fire.

I saw that his eyes were closed, his miscellaneous thoughts were exhausted, and he felt the spiritual meaning contained in the runes in his mind, and the spiritual power of the fingers flowed out and carved on the rock.

At first, the speed of his fingers was extremely slow, and it took him half a day to move an inch, but the more he went, the faster he went, and finally he finished carving a whole rune like a cloud.

Its shape is exactly the same as that of one of the four sheets of paper, but it has been magnified several times, and most of it is engraved on the ground from the top of the stone platform downwards.

After carving the first array, Han Li paused for a moment, then slowly exhaled and came to the right side of the fire pond to continue to concentrate on the carving......

After a long while, Han Li straightened up and slowly opened his eyes, and saw that the formations around the fire pond had all been depicted, and although they were in different positions, they were all related to each other, and they looked like they were all one and full of spiritual intent.

He nodded with satisfaction, rubbed his hands in front of him, and the Flame Firebird flashed out of his body, flew into the fire, turned into a silver flame, and burned fiercely.

As the silver flame lit up, the entire cavern began to heat up.

With a wave of Han Li's palm, a series of cyan light burst out, and after hovering in mid-air, the cyan light disappeared, revealing seventy-two green bamboo bee cloud swords, which hung neatly in front of him, and the blue light of the sword body flickered, emitting bursts of trembling sounds.

"Go"

Han Li opened his mouth and let out a soft snort, his sleeves slamming violently.

All the green bamboo bee cloud swords immediately swept backwards and retreated into the fire pond behind them.

I only heard a sharp roar from the silver flames, and the raging silver flames suddenly surged out, instantly submerging the seventy-two green bamboo bee cloud swords.

Han Li then sat down cross-legged, pinched out a strange spell with his fingers, and silently chanted it in his mouth.

As the sound of chanting continued to sound, there was a burst of "buzzing" sound from the magic circle engraved around the fire pond, and four thick golden pillars of light shot out diagonally from the surroundings, intersecting in the middle of the fire pond, turning into a golden light curtain, enveloping the Green Bamboo Bee Cloud Sword and the Jingyan Firebird.

After a moment, Han Li's ten fingers parted and bent slightly in front of him, hooking upward.

The sound of the bottle being uncorked sounded at the same time, and all kinds of spiritual liquid in the dozen or so gooseneck bottles flew out and poured into the golden light curtain.

Through the golden light curtain, Han Li could clearly see that the molten gold of the Verge Essence Gold dispersed on its own, heading towards the Green Bamboo Bee Cloud Sword, each of which was completely wrapped in it.

Immediately after that, several other kinds of spiritual liquid were also divided into seventy-two points, and bit by bit they merged into the Pure Gold Melt of the Pattern wrapped in the Bee Cloud Sword.

Seeing this, Han Li closed his eyes again, his divine sense suddenly released, and he threw his mind into the golden light curtain.

I saw that the golden light curtain trembled slightly, and the light on the surface was magnificent, and it instantly turned into a colorful color.

At the same time, the seventy-two green bamboo bee cloud swords also began to light up with bursts of light, as if hanging rainbows and becoming colorful.

After such an hour, Han Li opened his eyes again, and as soon as he opened his mouth, a baby flame gushed out from his mouth and hit the multicolored light curtain, and without the slightest hindrance, it directly merged with the silver flame.

"Hoo ......"

The two flames merged, and instantly rose up, turning into a pillar of flame light, enveloping the Green Bamboo Bee Cloud Sword in it.

At this moment, a sudden change occurred!

More than a dozen flying swords seemed to be unable to stand the burning of this fusion flame, and they actually struggled frantically, and one by one the sword qi overflowed, cutting in all directions.

Seeing this, Han Li's majestic divine sense suddenly surged away, instantly connecting closely with each flying sword, suppressing it as soon as possible.

"I didn't expect that there were still some stubborn sword elements that hadn't been fully fused, and they were so ......deeply hidden," Han Li sighed lightly, but he was a little happy in his heart.

Fortunately, these sword elements were attacked at this time, if he was at war with people, he was afraid that the Qingzhu Bee Cloud Sword would get out of control for a moment, and it might cause irreparable consequences.

I saw that in the midst of the flames, on the green bamboo bee cloud sword wrapped in various spiritual liquids, clumps of sword elements that had not yet fused overflowed from the sword body one after another, and they shattered directly.

However, the spiritual power it transformed into was not lost, and it was reabsorbed by the flying sword.

Seeing this, Han Li did not relax at all, he still carefully controlled the fusion of the infant fire and the silver flame, constantly burning the seventy-two flying swords, and the rainbow color on the flying swords gradually faded and became blurred......

Seventy-seven forty-nine days later.

Within the golden light curtain above the fire pond, seventy-two flying swords were as white as jade, transparent as ice, and looked as transparent.

Compared to the original, the blades of all the flying swords seemed to be elongated by an inch, and the blades were much wider.

Han Li looked at the Green Bamboo Bee Cloud Sword, which looked a little unfamiliar, with an expressionless expression, and waved his palm again.

On the stone platform, the cork of the last black stone bottle flew out on its own, and the milky white spiritual liquid contained in it flew up leisurely, entered the golden light curtain, divided into seventy-two drops, and dripped on each flying sword.

"Tick ......"

This sound is soft, like rain in early spring, like a spiritual spring splashing, like dead wood in spring.

All the flying swords trembled at the same time, and then the spirit patterns on the surface suddenly lit up, and at the same time, the golden light was magnificent, and countless golden thunder threads shot out, intertwining with each other, like a small thunder and lightning forest, and there was a continuous "crackling" sound.

If it weren't for the golden light curtain outside, I was afraid that these thunderbolts would spill out and blow up this cave.
