Ye Yu threw the palm-sized phalanges into the tripod with his left hand, and then took out the trace of the Yuan Shen from the wolf tooth knife, Zhang Haiyun's Yuan Shen was languishing, and there was no longer any soul, Zhang Haiyun's soul had been completely wiped out by Ye Yu, so Ye Yu dared to use this Yuan Shen as a tool spirit and threw the finger bone into the Dan furnace.

Immediately after, Ye Yu threw the wolf tooth knife and Leng Yue into it, and not only that, but he also dripped a drop of natal essence blood.

Ye Yu is currently unable to cast the Samadhi True Fire, which is related to the realm, but he has the Xuanhuo Dao and the flame of Amaterasu, which is enough to replace the Samadhi True Fire for refining.

The golden flames and the Amaterasu flames of the Hesse Forest were all sent to the ding, and the valley where the night feather was located was so conspicuous under the moonlit night, fortunately, there were no people here, otherwise, the shining fire was enough to attract the cultivators.

Ye Yu began to meditate on refining the flying knife in the ding, he carefully controlled the Xuanhuo to wrap the finger bone with those materials, and then began to smelt towards the flying knife in his heart.

When the time was almost ripe, Ye Yu threw a trace of the man in black into it, without any sound, and it was very subtle and perfect to melt into Jiuding.

Then, Ye Yu quietly crossed his knees on the ground, quietly watching the changes in the Ding Furnace, and the Xuan Huo in the Ding Furnace was still burning brilliantly.

However, Leng Yue, the Wolf Tooth Knife and those materials have slowly begun to melt under the blood of the finger bones and Night Feather's natal essence, and at this rate, he can condense the flying knife he wants in half a month at most.

The process of waiting in the middle can be described as quite tiring, and if you have bad patience, you will have to go crazy a long time ago. However, Ye Yu had long been accustomed to the taste of being alone, and besides, while he was condensing the natal magic weapon, he could still cultivate demonic qi, which was not wasted.

Time passed bit by bit, half a month passed in a blink of an eye, the fire in the brilliant Ding Furnace had been extinguished, and a strong pressure was in the Dan Furnace, Ye Yu couldn't perceive it, but he knew that the flying knife he had been waiting for for a long time had finally been practiced.

At this moment, Ye Yu's heart couldn't calm down, no matter how he said that this was also his first time refining weapons, and it was to practice the natal magic weapon, it was absolutely impossible not to be excited.

The moment the Ding furnace was opened, a heavenly thunder fell out of thin air and fell into the Dan furnace without any cost.

"Boom"

The deafening sound was so terrifying at this time, Ye Yu's heart tightened, he didn't know why there was a thunder descending the world the moment he opened the Ding Furnace, which was not recorded in the Taixuan Sutra.

After he put the Ding furnace into the Xuanhuang Ring, a flying knife the size of a palm was quietly suspended in front of him, and Ye Yu lifted the fairy pupil to watch, this knife did not have the amazing breath that he imagined, could it be that it was split by the heavenly thunder just now?

Ye Yu couldn't help frowning, this was the flying knife he had been looking forward to for a long time to use as a natal magic weapon, and it was actually scrapped before it was used, how could he be relieved?

However, when he thought that this flying knife could float in the air without anyone to control it, Ye Yu's eyes suddenly bloomed with essence, and then he dripped a drop of his own essence blood into it, and suddenly a feeling of blood connection arose.

The moment this pure black-gold knife appeared on the foundation building platform, Ye Yu suddenly felt a breath of destruction and destruction, and the sea of aura seemed to be about to be broken by this strong sword intent.

Ye Yu's heart moved, this black-gold flying knife suddenly appeared a hundred miles away, without any expenses, a piece of boulder turned into powder, he felt quite satisfied, and couldn't help but say to himself: "The legendary Xiao Li flying knife should be like this, right?"

Ye Yu looked at the natal flying knife in his hand, the more he looked at it, the more satisfied he became, there were inexplicable lines on this flying knife, he knew that it was the cold moon wolf tooth knife and the best spirit stone plus his natal essence blood to form the lines, on the other side of this flying knife a tiny font loomed, if it wasn't for Ye Yu watching it wholeheartedly, it would be difficult to find.

"What is this word?"

Night Feather was surprised to find that he didn't know that word, as if it was not inferior to the words of this era.

When he let out a trace of spiritual sense and probed in, a domineering word appeared in his mind

"God!"

"Originally, I wanted to name you Night Knife, since you already have a name, then, from now on, you are my Ye's first natal magic weapon, take a name, destroy the gods!"

Ye Yu looked at the quaint knife in his hand, and when he learned what the inexplicable words were, the three words of the God Destroying Knife appeared in his heart, as if the name of this knife was God Destroyer.

Originally, he wanted to take another name, what was the Soul Exterminating Knife, or the Soul Snatching Knife, but after he knew what words were engraved on the blade, he decided on the name of this flying knife, the God Exterminating Knife!

"As soon as the god-destroying knife comes out, it will behead its primordial god. This sentence involuntarily appeared in Ye Yu's heart.

Ye Yu put the God Destroying Sword into the Dao Platform, pulled out the Water God Sword, stepped on the flying sword, and rushed towards the undead at full speed, at the moment when the flying knife entered the Dao platform, the blade of the knife that originally had only one word, but a second word appeared, a common text in the Xuanwu Continent, 'Extinguish'.

Only when Night Feather fights with this flying knife in the future, can he notice the change of this knife, this is a flying knife that is not weaker than the innate spirit treasure, and it can also evolve because it has a machine spirit!

Night Feather galloped all the way, while thinking, that day, in the valley of the undead, the chief of the tooth had said about the Demon God City, but he did not describe it specifically, nor did he tell him that there were 'demon spirits' in the Demon God City.

"In the demon world, it is divided into one city, nine counties and eighteen villages. In every county city, there is a ghost demon spirit sealed, this ghost spirit is the natural embodiment of heaven and earth, and there is also a legend that it is the remnant soul of the heaven-swallowing beast Netherworld, but no matter which way it is said, it is detailed that it has great magical powers.

Once the cultivator fuses with it, its cultivation can skyrocket, and at the same time, it can also obtain some powerful magical powers, according to the description in this Haiyun's memory, every Netherworld Demon Spirit is a rare thing in the world, and after fusion, there is a certain chance to enter a realm called 'Emptiness'. ”

"The so-called 'meaning of emptiness' is an extremely wonderful realm, once a cultivator enters this realm, the speed at which he comprehends the laws of heaven and earth will reach an incredible level, if only that, it is the most attractive, and can make all cultivators crazy. It is that once you enter the realm of this 'meaning of emptiness', there is a certain chance that you can create your own mystic method according to your own artistic conception!!"

"It is rumored that some cultivators in the Transformation Stage back then created their own when they entered this realm at a great price."

Night Feather is still very fascinated by the realm of emptiness, and that invincible belief will definitely make people addicted and sinking.
