The corpse of the steel ghost completely dissipated, and Xiao Yu was the only one left in the entire cave.

"What about this thing. Xiao Yu turned his head and couldn't help frowning when he saw the layer of human skin that the steel ghost was wearing before

"Burn it, it's disgusting to look at. After pondering for a while, Xiao Yu pulled up Huang Gang's human skin, shook his head and said.

However, just when he released a flame and planned to burn the human skin with a fire, he seemed to suddenly think of something, and immediately extinguished the flame in his hand.

"No, no, Sen Miao watched me bring Huang Gang into the cave, if I want to burn this skin too, then he will ask me about it at that time, but there is really no proof of death." ”

Thinking of this, Xiao Yu shook the human skin, and then threw it into the Huaxia realm.

"Hey... How did this come out one after another, since I came to the Blue Lotus Sect, it hasn't stopped at all... Xiao Yu said with a wry smile.

Then, he tore open the torn robe on his body and looked at the wound on his chest.

"It's a claw, but if I had stabbed that dagger, it wouldn't have been so easy to recover. Xiao Yu gently covered the torn robe, then flipped his wrist again and took out the fragment of the Killing God Sword that he had hidden earlier.

"It's more important to kill the sword, as for the alchemy... I'll talk about it when I have time. Xiao Yu glanced at the two Dan furnaces in the cave and left the matter of alchemy behind.

"Hmmm... ”

Immediately after, Xiao Yu slashed his finger with the fragment of the Killing God Sword and sprinkled a few drops of blood on it.

"Buzz... ”

At the same time, there was a slight tremor on the fragment, and immediately after, a dazzling light shot out from it, hitting Xiao Yu's eyebrows.

With his previous experience in fusing the fragments of the Killing God Sword in the Tower of Babel, Xiao Yu didn't take this matter to heart, and when he saw that the light fused on the phantom of the God Killing Sword, he calmly withdrew from his sea of knowledge space.

However, at this moment, Xiao Yu seemed to realize something, and couldn't help frowning and falling into deep thought.

"I remember when I was at the gate of the Tower of Babel, my sea of knowledge was closed... Can... But why was I able to see the fusion process of the Killing God Sword at that time?"

"Could it be that the Killing God Sword is really more special than the power of the Heavenly Dao Origin? Or ... The Divine Sword of Killing is completely above the origin of the Heavenly Dao... That's why my sea of consciousness was forcibly opened because of its mutation?"

After thinking for a moment, Xiao Yu couldn't help but shake his head: "Hey... Whether it's the Sword of Killing God or the Tower of Babel, it's so weird.,I guess even if I want to break my head now.,I can't figure out the reason.。。。 Forget it, let's take one step at a time. ”

Then he looked at the metal fragment in his hand.

"Last time, I didn't see how you guys fused together.,This time... I'm going to see what you can do with it. ”

With that, Xiao Yu held up the metal fragment with his left hand, and summoned the hilt of the Killing God Sword with his right hand.

Immediately afterwards, Xiao Yu did not hesitate to touch the two together.

"Buzz... ”

At the same time, a trembling hum came from the place where the two touched, and immediately after, a dazzling bright light suddenly burst out, shaking Xiao Yu so hard that he couldn't help but close his eyes.

However, a moment later, when the strong light dissipated and Xiao Yu opened his eyes slightly again, he found that the metal fragments in his hand and the hilt of the Killing God Sword were all gone.

"... It's still not for the big girl to change her clothes, as for being so twisted and pinched. Xiao Yu shook his head with a hint of loss and impatience and said.

A moment later, he summoned the hilt of the Killing God Sword again, and carefully observed it left and right.

"Nothing has changed... What the hell is this fragment for... Xiao Yu searched for a long time, but he didn't find any changes on the hilt of the God Killing Sword, so he sighed and muttered.

"Could it be that if the fragments are not together, the Killing God Sword will not react at all?"

"Or is this fragment not an important part? or... ”

Thinking of this, Xiao Yu sank into his sea of consciousness again, and circled around the phantom of the Killing God Sword a few times.

"Sure enough, neither of these two pieces is next to the hilt of the sword... ”

It turned out that the fragment of this fusion was the same as the previous time, and there was still a considerable distance between it and the hilt of the God Killing Sword, and that was definitely where another fragment should exist.

"It seems that only by finding the fragment that is close to the hilt of the sword can I make the sword change. But... Speaking of this, Xiao Yu frowned again: "The Huanyun Realm is so big, the ghost knows where that fragment is hidden... ”

After a while, Xiao Yu shook his head helplessly, put away the Killing God Sword directly, and then looked at the two heavy Dan furnaces.

"Forget it, let's work first, otherwise my second master will definitely not let me out. ”

With that, Xiao Yu walked step by step to the black Dan furnace on his left, and sat cross-legged to release the fire attribute aura.

A moment later, the pitch-black Dan furnace was burned red by the flames, but Xiao Yu had no intention of taking out the medicinal materials, still closing his eyes and outputting his aura.

"There's a ghost in this stove... After about a stick of incense, Xiao Yu opened his eyes and looked at the huge Dan furnace with a red body in confusion.

"My aura ... It was as if it had been swallowed alive, and it was not transmitted to the furnace at all... ”

"It's burning red on the outside, but the temperature inside can't come up, how can you use this thing to refine the pill? Xiao Yu withdrew his hands dissatisfied, and looked intently at the red Dan furnace and said.

"It's really evil.,Who made this broken furnace?This thing is useless at all except to stir up the situation.。。。 ”

"Besides, I feel that it consumes no less than five times more spiritual energy than an ordinary Dan furnace, not to mention other people, even if it is me, it is impossible for me to refine a furnace of elixir. ”

"Forget it, let's study the other one first. Then, Xiao Yu gave up his intention to continue the stalemate with it, and walked directly towards the other Dan furnace on the right hand.

"These two... It looks exactly the same, so it can't be the same cheating thing. After speaking, Xiao Yu sat cross-legged in front of the Dan furnace and pushed the fire attribute aura in his body to his hands.

"Whew... ”

In the next second, two stout fire snakes erupted from Xiao Yu's palms, enveloping the belly of the Dan furnace as if spiritually, frantically releasing their own temperature.

However...

"Shhhhh Xiao Yu took a breath and couldn't help but open his eyes again.

"This Dan furnace is not as good as the one just now... Xiao Yu withdrew his hands depressedly and pressed back the majestic aura in his body.

"This broken furnace is even more unsuitable for alchemy, I have a stable output of spiritual energy here, but you are crazy to tear down the stage for me, and live or die without letting the flames scorch the bottom of the furnace... What kind of pill is this? ”

Thinking of this, Xiao Yu sat on the ground and leaned back with his arms on his pillow.

"It's a big deal, Master doesn't need you, anyway, the Heaven Replenishing Pill can only be refined by the Huanyun Refining Heavenly Furnace. Xiao Yu looked between the two Dan furnaces for a moment, and then retracted his gaze to summon the Huanyun Refining Heavenly Furnace.

However, at this moment, Ye Lao's voice suddenly remembered in Xiao Yu's heart: "Disciple, haven't you discovered his purpose?"

"Hmm, Master, who are you talking about?" Hearing Ye Lao's words, Xiao Yu suddenly sat up from the ground.

"Of course it's your new second master?"

"He, you say he has a purpose?"

"Of course, and when you went down to the valley, the master guessed what your second master wanted to do. ”

"Oh, Master, you mean... What's in there?"

"Hahahaha, it's not boring, but he does this as a way for the teacher to always want to train you. ”

"What, Master... You also want me to use these two rags for alchemy?" Xiao Yu said in surprise.

"Hahahaha, exactly, but the teacher is just a remnant soul now, and there is no way to get you these two treasures. ”

"Baby, can you still call these two things baby?" Xiao Yu couldn't help but say after a moment's pause.

"Yes, apprentice, don't underestimate these two Dan furnaces, their functions are really the right medicine for you. ”

"This... Master, I still don't quite understand, what is so good about this kind of Dan furnace, does it have any other function besides making it more difficult for me?"

"No, what the teacher said is just such a function. Ye Lao paused and continued: "First of all, the purpose of that Spirit Sucking Pill Furnace is to train you on how to control your spiritual power, avoid the outer layer of Spirit Sucking Array, and send the flames directly into the Dan Furnace. ”

"However, the Swinging Spirit Pill Furnace is to exercise your precise control of your own spiritual power, avoiding the Swinging Spirit Formation generated by the Dan Furnace, and accurately concentrating the spiritual energy in the furnace. ”

"Moreover, with the mottled and mixed fire attribute aura in this cave, it can even improve your control over your own aura to a further level, so for the sake of the teacher, these two Dan furnaces are just the right treasure for you. ”

"You mean ... After listening to Ye Lao's words, Xiao Yu couldn't help but think for a moment and said, "Youlian Sanren didn't just take two Dan furnaces to fool around? Deliberately training my control of Reiki?"

"That's right, besides, although your Huanyun Refining Heavenly Furnace is good, it can't improve your ability to refine pills at all. ”

"So ... My second master is really well-intentioned... ”
