The sword slave was slightly stunned, and immediately understood the meaning of Lao Xiaotou's words, walked to the bone spur, and after reaching out and grabbing the most powerful bone spur, all the bone spurs around him followed the sword slave as if they were activated.

"Can you control them?" Old Xiao Tou couldn't wait to know the answer, he had discovered that there was some kind of connection between the Immortal Pill and the Xuan Immortal Array, and that was just his guess.

"I'm working on it" The sword slave pushed his hands into the air, and the bone spurs around him also floated in the air, and then slid in the direction of his fingers. However, the entire Xuan Ying Array was still not opened, and Lao Xiao Tou still couldn't feel the powerful suction.

"This won't work, you can turn into a sword body and try it" Old Xiao Tou shook his head, and then ordered the sword slave.

The sword slave nodded, her figure becoming fluttering like a puddle of water, and before long, she was completely transformed into a long sword. Suddenly, in the entire mine, the sword qi immediately permeated, and the seven sword bones in her body seemed to be activated, weaving a dense network with sword qi in mid-air.

At the same time, the king's bone spur on the ground also slowly floated up, and it seemed to be attracted by the Stygian Pill, shooting out several slender rays of dark light towards the hilt of the sword.

Then it flew into the air, swirling around the sword, becoming one of its secondary swords, the Loyal Guardian Sword. At this moment, the sword slave let out a surprise shout in mid-air: "Master, I can control the Xuan Nether Array."

Whoosh! Eighty bone spurs on the ground were sucked into the air by it, and then the bone spurs rotated around her, forming a ninety-nine superposition array, and the incomparably powerful suction force immediately made Old Xiao Tou dodge in panic.

"Can you control this suction?" Lao Xiao touched his forehead embarrassedly, and secretly thought: "What if I hurt my own people in the battle array?" ”。

The sword slave once again sucked the bone spurs to her side, and after trying to arrange several formations, she spoke: "Master, I have already mastered the Xuan Ying Array, you can walk in and try it again."

Old Xiao Tou glanced into the air with doubts in his heart, and then stepped in, sure enough, this time he didn't feel anything abnormal, but as long as he got closer to the bone spur, the more severe the chill on his body, and finally forced him to have to use his luck to resist the power of the flame rage in his body.

"Can't you get rid of this chill?" Old Xiao Tou observed for a long time before he said.

"Master, this cold qi is the accumulation of the underworld beast before the bone fragment, not the acquired refining, so it can't be expelled" The sword slave waved his hand, the bone spur fell to the ground, and he also converted from the sword body to the main body, and the king's bone spur still kept circling her.

"It seems that we still need to create a set of armor for this underworld army," Old Xiao Tou thought about it and said.

"But there are only three days left before the battle of the founding of the clan, are we still in time?".

"It's man-made, call Hong Laosi immediately, and then ask Boss Yan to send a few clan soldiers over to help."

"Yes".

Not long after, Hong Laosi led a team of clan soldiers into the cave, and he asked Lao Xiao with a blank expression: "Clan master, do you really want to refine weapons here?" ”。

"Of course! You go find more than a dozen bone furnaces and arrange them in the Earth Flame Pool according to the direction of the Fire Gathering Array, so that they can absorb the power of the flames of the Earth Flame Vein, and I believe that they will definitely be able to increase the speed of the refining weapon" Old Xiao Tou had the understanding of refining the weapon just now, so he remembered to arrange the Fire Gathering Array in the Earth Flame Vein, and use the power of the Earth Flame to refine the weapon.

"Clan Master, is this really possible? In case..."Hong Laosi is still very cautious, he doesn't want to destroy all his family wealth in the past few years in this fire pool.

"How do you know if it will work if you don't try" Old Xiao Tou did not hesitate at all, and immediately beckoned someone to throw the bone furnace into the Earth Flame Pool. With a few grunts, the bone furnace disappeared without a trace, and the expression on Hong Laosi's face kept twitching.

It wasn't until the last bone furnace also fell into the Earth Flame Pool that Lao Xiao Tou stopped, and then turned around and jumped into the Earth Flame Pool, a move that made Hong Laosi almost not exclaim.

He didn't believe that anyone else could get into something as terrifying as the Earth Flame Vein without any defense, but the facts made him have to believe that the scene in front of him was real.

Old Xiao Tou burrowed into the bottom of the Earth Flame Pool, and immediately injected the power of furious flames into the bone furnace, and he replaced the weapon disciple with himself, and refined the eighty-one armors in the bone furnace with the Gathering Fire Array.

Refining eighty-one armors at the same time in one breath, no one will believe this courage! But Hong Laosi saw it with his own eyes today. Although he couldn't enter the Earth Flame Pool, he couldn't know what was going on inside, but he could sense the changes in the more than a dozen bone furnaces through the Gathering Fire Array.

Time passed little by little, two days passed in a blink of an eye, Lao Xiaotou still hadn't come out of the Earth Flame Pool, and everyone in the cave didn't have their eyes for a moment, they were all waiting for the last moment to come.

Especially Hong Laosi, he wanted to witness a pioneering feat in the history of refining with his own eyes, and he was very much looking forward to what grade the bone weapon would be refined in this way.

He had already sensed from the fluctuations coming from the Gathering Fire Array that the armor in the bone furnace had been formed, and now he was only a little short of ready to refine the furnace.

He approached the Earth Flame Pool, staring at the flames with his eyes, eager to jump into the bottom of the pool immediately to take a peek, and at this moment, the Earth Flame in his eyes, which had been calm, suddenly became restless.

Waves of air broke through the surface of the Earth Flame Pool, spraying into the air, and then the fire in the pool was monstrous, as if it was about to burst out in an instant, such a shocking natural landscape immediately aroused the vigilance of the entire Sifang Mountain, and they all put down their work and gathered together in the direction of the Earth Flame Cave.

At this time, Hong Laosi's expression became more and more nervous, he suddenly turned around, and shouted: "Everyone quickly exit the cave, let everyone leave this mountain range" He had already realized what was about to happen at this time, he no longer dared to hesitate, and unfolded his body and ran towards the outside of the cave.

There was a lot of noise everywhere, and countless figures ran towards the bottom of the mountain, and before they could escape from the mountain, they heard a series of loud explosions behind them. Countless magma dragons erupted from the rock mass and soared into the sky.

Such a spectacular natural volcanic eruption immediately made everyone present fall in love with it, and they all felt the strength of the force of nature, and at the same time, they were also extremely afraid of the volcano in front of them. They ran for their lives, and the ground trembled so violently that they could not hold their feet on the ground, and they almost fell down the hill with a roll and a roll.

When they left this mountain range, they had already turned into a sea of fire behind them, countless molten mava had spread all over the mountain, and countless air currents and flames were sprayed into the air, and smoke and dust covered the entire Sifang Mountain.
