"Shadowflame!"

Looking at the flame suspended in front of Ruohan with an almost transparent color, Wan Yin's heart was shocked, and he understood that this was the legendary shadow flame, a soul shadow flame that could only be born by condensing the power of the soul shadow to the extreme.

Shadow Flame, only when the power of the soul shadow reaches the level of the Four Pattern Dao Masters, it is possible to condense a trace of Shadow Flames, and the Four Patterns Dao Masters, their attack power far exceeds that of ordinary Shadow Cultivators of the Four Spirits Realm.

A large part of the reason why the attack power of the Four Pattern Dao Masters far exceeds that of ordinary shadow cultivation is because of the existence of this shadow flame, in the face of this shadow flame, even if the shadow power cultivation has reached the four spirit realm, they dare not have the slightest slackness, after all, as long as they are hit hard by this thing, it is very likely that they will leave some extremely serious sequelae.

Shadow Flame does not do much damage to the body, but it has an extraordinarily strong corrosive power against the Soul Shadow.

After summoning the shadow flame, Ruohan's complexion also slowly became solemn, and with a wave of the jade hand, the shadow flame spread out, enveloping the Chiluan Ancient Spear.

"Squeak!"

With the surging of shadow flames, the Chiluan Ancient Spear suddenly trembled violently, and the body of the spear, which was quite simple, also became a little red.

In this case, Ruohan's face remained unchanged, and he opened his mouth to spit out a cloud of shadow flames, wrapping a piece of gray-white metal material in it.

These metal materials were purchased by Ruohan at a great cost, and Tuo Qianjun bought them in some auction houses and other places, and it cost tens of thousands of medium-grade shadow stones, such a large amount of expenses, if it wasn't for the scavenging from Shili's storage bag, Wan Yin wouldn't have been able to take it out himself, but Rao was like this, and he almost spent the shadow stones, leaving less than 30,000 medium-grade shadow stones...

"Whew!"

Under the scorching of the shadow flame, the hard metal material also gradually melted at a slow rate, and some gray-black impurities dripped down from it and fell on the floor, corroding into tiny holes.

Wan Yin sat quietly in the cave, watching Ruohan's every move without blinking, he was also a Dao Master, he could feel that while refining the metal material, the latter's soul shadow power actually poured into it into thousands of threads, changing into countless subtle structures, this is an extremely complex control, and only a strong person with a strong soul shadow power can do such a subtle control.

Under Wan Yin's gaze, the dark metal material, after consuming a full five hours, completely turned into a viscous gray liquid.

After the quenching was completed, Ruohan's slender jade finger was lightly touched, and the gray-white liquid was extremely evenly spread on the Chiluan Ancient Spear.

"Snort!"

As these gray-white liquids were smeared, the Chiluan Ancient Spear trembled more and more intensely, and those liquids were also refined by the Shadow Flame, blending into the spear body bit by bit, making the color of the ancient spear gradually have a trace of gray-white luster, and faintly, the spear body became sharper.

After completing this step, Ruohan began to refine other materials, for these repetitive actions, Wan Yin did not show the slightest boredom, and looked intent, like a studious disciple, any subtle movements of Ruohan were included in his mind.

This kind of continuous refining material lasted for a whole day, and Wan Yin did not close his eyes during this period, and his cultivation reached the point where he didn't sleep for ten days, it was nothing, and his strong body was enough to cope with the exhaustion in the eyes of these ordinary people.

In the evening of the second day, the last metal material was also melted into a liquid and adhered to the Chiluan Ancient Spear.

At this time, the color of the Chiluan Ancient Spear was slightly colorful, different from the original ancient color, and each place had some different colors, which was because the refining had not yet been completely completed.

"Whew..."

After refining the last material, Ruohan also breathed a sigh of relief, glanced at Wan Yin, and said lightly: "I'll reply first, and then start the last step, this step, I will integrate the beast crystal essence into it, this last step, and the various characteristics of these rare materials, are all integrated into the ancient spear, at that time, the ancient spear will evolve into a high-grade shadow weapon." ”

After all, it is a remnant soul state, and it is expected that it cannot be held for too long.

Hearing this, Wan Yin nodded heavily.

After the words were spoken, Ruohan closed her eyes directly, and recuperated for two full hours before she opened her eyes, at this time her soul shadow power had almost recovered, and then, her eyes were slowly solemn, her red lips were open, and an extremely majestic soul shadow power surged out, wrapping the Chiluan Ancient Spear that became beautiful.

"Boom!"

A wave of heat spread in the cave, this heat wave is very strange, obviously not too hot, but it makes people feel like they are in a furnace.

One after another the power of soul shadows poured out from the sea of ten thousand hidden souls, enveloping all the bodies, and the strange heat wave dissipated into invisibility, her gaze stared at the Chiluan Ancient Spear that was wrapped in the raging soul flames, she knew that now was the most critical moment.

"Squeak!"

In the face of the shadow flame, which had become much more fierce in vain, on top of the Chiluan ancient spear, there was actually a trace of green smoke seeping out, and the many liquids that adhered to the surface of the ancient spear were also boiling, and under the pressure of the shadow flame, it continued to erode into the inside of the ancient spear a little bit.

"Buzz!"

As these metal characteristics invaded the inside of the ancient spear, the balance in it seemed to be broken, the spear body trembled wildly, and there was a faint buzzing sound coming out of it, and a dazzling strong light also burst out from the ancient spear, and the sharp luster shot out all over the cave, and the luster was full of strong destructive power.

"Humph!"

Feeling the resistance of the ancient spear, Ruohan also snorted coldly, and a powerful soul shadow power surged out, forming a soul shadow prison, wrapping the luster around the Chiluan ancient spear, and those lusters were soaring on the soul shadow prison, shaking ripples, and then they dissipated.

"Whew!"

When these shiny rays were shining at the same time, they could only be seen above Ruohanyu's hand, and I don't know when, a flashing red thunder mang was suspended in it, and then, that red thunder mang was flicked by his fingers and flew straight into a small hole specially left by the Chiluan Ancient Spear when it was refined.

The moment the red thunderbolt entered, the ancient spear seemed to tremble violently at this moment, and its fierceness was even more fierce than before.

This is the most critical step, the integration of the core things!

"Give me fusion!"

Ruohan's eyes were solemn, and then the jade hand suddenly clenched, and the shadow flame wrapped in the Chiluan Ancient Spear shrank fiercely.

"Whew!"

With the fierce compression of the shadow flame, all the metal liquid on the ancient spear, including the red thunder, was directly pressed into the ancient spear.

Suddenly, the brilliant luster burst out from the Chiluan Ancient Spear, and the surrounding soul shadow prison was directly pierced by the sharp luster, leaving a bottomless black hole on the ground.

"What a powerful shadow machine!"

Seeing this scene, a look of surprise flashed in Ruohan's beautiful eyes, and then the jade hand grabbed it in the air, and an invisible soul shadow big hand firmly grasped the ancient spear that burst out with a brilliant luster.

Wan Yin looked at the Chiluan Ancient Spear struggling in Ruohan's hand with a little nervousness, he could vaguely see that in the surge of light, the shape of the Chiluan Ancient Spear seemed to be undergoing subtle changes, and the fierce taste was getting stronger and stronger.

"Buzz!"

The rapid humming sound continued to come out from the Chiluan Ancient Spear, and later, that humming sound seemed to gradually evolve into an extremely low and peculiar luan sound.

That kind of sound quietly echoed in the cave, but it made the faces of De Wanyin and Ruohan change a little at the same time, obviously unexpectedly, this ancient spear could actually emit the sound of the legendary super shadow beast.

"Whew!"

In the midst of Ruohan's shock, on the Chiluan Ancient Spear, the strong light was so strong that it directly exploded its soul shadow hand, and an extremely sharp light burst out, directly blasting the top of the cave out of a deep pit.

"Come here!"
