After expelling the mysterious power in his body, Gu Chen did not linger and returned to the Killing Gate, and the temporary retreat of the Demon made the entire Blood Domain settle down again, but everyone knew that this would not last long, if the Demon recovered the eighteen heads, then the only ones who could fight with it were himself and Chu Zun, so at this moment, the success or failure of the Blood Domain was pressed on the two of them, and this pressure was not small.

For a few months after returning to the Killing Gate, Gu Chen was thinking about how to kill the Demon of the Underworld, the previous sixteen heads of the Demon Demon had such a powerful power, although the Demon of the Soul had recovered to seventeen and fled, but Gu Chen knew that if the Demon of the Heyday had seventeen heads, then Gu Chen and the First Venerable would be defeated, and these seventeen heads might have reached the realm of the Dao Ancestor, in this way, the eighteen heads of the Demon of the Underworld would have reached the realm of the Extreme Ancestor, and who could compete with the Extreme Ancestor Realm?

It is rumored that only the master of Jing Wuxian and Jing Wushuang has reached the realm of the Extreme Ancestor, but this is just a legend, after all, no one has ever seen that strong man, and in the memory of the Mirror Without a Trace, Gu Chen has never received the slightest news about this person, but Gu Chen knows that the ancestral realm is powerful, the difference in strength between Fan Ancestor and True Ancestor is 100 times, the difference in strength between True Ancestor and Dao Ancestor is 1000 times, and the difference in strength between Dao Ancestor and Dao Ancestor is unknown, but in terms of the difference in strength before, Gu Chen speculated that the difference in strength between this Dao Ancestor and the Extreme Ancestor has reached at least 10,000 times, if this is the case, As long as the demon has eighteen heads, no one will be the opponent of the demon.

Gu Chen tried all the methods, but he couldn't seem to find any way or magic weapon that could resist the eighteen heads of the demons, the only ancestral weapon Heaven and Earth Roulette Gu Chen couldn't use it yet, and the four great saints who could use the Heaven and Earth Roulette were only cultivators of the Venerable Realm.

Gu Chen once saw a thing in the memory of the mirror without a trace, named Tian Yuan, this thing is very powerful, it can wipe out the mirror without a trace, and this thing should be a thing without a trace of the mirror, otherwise the mirror without a trace should be uncontrollable, but this memory does not mention this thing at all, Gu Chen doesn't know why, if he can get this thing, then the odds should be more.

At this moment, Gu Chen couldn't think too much, Gu Chen just wanted to connect all the memories of Jing Wuxian and ask for more useful information from them, but this seemed to be impossible at all, and that memory didn't seem to be able to be connected if he wanted to, but had special limitations.

"Ancestral artifact?" Gu Chen seemed to realize something, and directly summoned the First Venerable.

"Little Gu Chen, what's the matter? Can you stop being like this? I'm an old man who can't stand your toss like this, you said that you didn't come to me if you had something, but let me, an old man, come to you," Chu Zun said with a blow of his beard and glaring.

"Chu Zun, there is indeed something important this time, dare to ask Chu Zun how much he knows about the ancestral weapon?" Gu Chen asked.

"Ancestral Artifact...... I don't know much, but I can also give you a general explanation, the ancestral weapon is made by the strong man of the ancestral realm who steals the essence of heaven and earth and integrates it into his own power, and the ancestral weapon has the advantage of being able to improve the class, how can you be so interested in the ancestral weapon? Chu Zun looked at Gu Chendao.

"Nothing...... I just want to refine an ancestral weapon, I don't know much about ancestral weapons, so I'll ask you," Gu Chen said.

"Huh...... Refining ancestral weapons is not so simple, not to mention the difficulty of refining ancestral weapons, even the things of heaven and earth that you need to refine ancestral weapons are difficult for you to collect" Chu Zun looked at Gu Chen and said with a smile.

"What if it's smelted with other magic weapons?" Gu Chen asked again.

"That's fine, but you also need to find enough materials to smelt the ancestral artifact, right? At least you can get some heaven-level magic weapons, but I have very few blood domain refiners, so there are very few magic weapons, and if you want to find enough things to smelt ancestral weapons, I'm afraid it will be a little difficult" Chu Zun said.

"What if it's made with a holy weapon?" Gu Chen said

"Hahaha...... Gu Chen, don't be kidding, holy weapon? Do you know how many holy weapons there are in my blood domain, and if I'm not mistaken, then there are four major holy weapons in the entire blood domain, right? Tianli Hellfire Prison, Mixed Yuan Tower, Seagod War Halberd and the Yin and Yang Diagram of the Soul of the Gods, you and I both know that these four holy weapons are divided into the Heaven and Earth Roulette, what is the Heaven and Earth Roulette, do you want to refine the Heaven and Earth Roulette into an ancestral weapon? Then why bother, the Heaven and Earth Roulette is a powerful ancestral weapon" Chu Zun Dao.

"In addition to these four holy weapons, you can see if this is also a holy weapon" Gu Chen said, forcing the Five Elements Heavenly Pillar out of his body, and after the Five Elements Heavenly Pillar appeared, it instantly turned into five huge pillars and stood in front of the two of them.

"This ...... What is it? Why is there such a powerful power of the five elements? Chu Zun was obviously stunned and asked.

"The Five Elements Supporting Heaven Pillar was refined by hundreds of Venerables of our domain in the last era, taking the ultimate five elements of the Blood Domain and refining, originally I wanted to use these Five Elements Supporting Heaven Pillar to kill the underworld, but I never thought that this Five Elements Supporting Heaven Pillar would undergo a mutation, and directly divided the Blood Domain into Three Realms, Five Domains and One Valley, and then I broke the Five Elements Supporting Heaven Pillar in order to restore the Blood Domain, but I didn't expect to get this holy weapon unexpectedly" Gu Chen said with a smile.

"If Gu Chen uses these Five Elements Heavenly Pillar to refine the holy weapon, it is indeed a good idea, but have you refined me? Don't be able to refine the ancestral weapon, but destroy this holy weapon," Chu Zun said.

"I know some refining techniques, but I don't have a complete grasp of it, but now is a special period, I should always give it a try, this Five Elements Heavenly Pillar has a very strong defense, and the attack is not weak, refining it into an ancestral weapon, maybe you can get unexpected results" Gu Chen said.

"Good...... Since that's the case, then I'll protect the Dharma for you, and you can refine it as soon as possible," Chu Zun said.

"Then let's start" Gu Chen smiled and took out the Yuanshi Sansheng Ding Dao, "Ding Ling, if you are still here, maybe I don't have to be so entangled" After finishing speaking, Gu Chen threw the Yuanshi Sansheng Ding, and the Yuanshi Sansheng Ding quickly became larger, Gu Chen completely released his karmic fire, holding the shrunken Five Elements Supporting the Heavenly Pillar in his hand and said, "Heaven and earth are not benevolent, now I, Gu Chen, will use the extreme five elements to cast a sword, and I will definitely kill the demon clan that invaded my domain."

Gu Chen put the Five Elements Supporting Heavenly Pillar into the Yuanshi Sansheng Ding in order, and began to burn it with karmic fire, but what is this Five Elements Supporting Heavenly Pillar? It was a holy weapon refined by a hundred Venerables together, and the hardness was terrifying, it had been scorching for several months, and there was still no sign of melting on the Five Elements Heavenly Pillar.

Three years have passed, and at this moment, the Five Elements Supporting Heavenly Pillar began to be burned red by the karmic fire, the power of the original karmic fire could burn everything in the world into nothingness, but Gu Chen only melted it this time, so the intensity of the karmic fire was greatly reduced, and ten years have passed, the Five Elements Supporting Heavenly Pillar has completely turned into a five-colored liquid, looking at this five-colored liquid, Gu Chen began to slowly fuse the five-colored liquid, and finally softened the liquid that the five-element supporting pillar turned into a shape that he thought was good.

A long sword with a red body appeared in the Yuanshi Sansheng Ding, the shape of this sword was obviously the long sword in the hand of the demon god, Gu Chen had a soft spot for the sword of the demon god because of the demon god, so he cast this sword into the sword of the demon god.

At this moment, the sword fetus has been completed, but this is only a sword fetus, if the next step is wrong, then this long sword will also be a waste, Gu Chen retained the powerful power of the five elements above the Heavenly Pillar when he cast the sword, Gu Chen took out a trace of his golden primordial god and began to slowly integrate into this sword body, as well as the power of the demon god, the power of the green hellfire, and finally separated the karmic fire, and also integrated into this long sword, these many powerful forces were fused into the sword body by Gu Chen, which took Gu Chen several years, At this moment, Gu Chen had already sensed this long sword, as if this long sword was originally a part of Gu Chen's body.

A few months later, the Yuanshi Sanshengding began to rotate extremely fast, the karmic fire rose to the sky, the karmic fire was wrapped in a thing, exuding a powerful power of the five elements, Gu Chen looked at the thing wrapped in the karmic fire and roared, "I use my own sword, I am bound to kill all demons, this sword is called Demon Breaker" After speaking, the karmic fire completely dissipated, and a long sword appeared in front of him, the blood-red sword body was crawling with black and cyan lines, and the powerful power of the five elements emanated from the sword body.

Gu Chen stretched out his hand and grasped it, and the long sword fell into Gu Chen's hand, the corners of Gu Chen's mouth turned up slightly and slashed out a sword towards the void in front of him, the void was torn apart in an instant, and the dozens of peaks in front of the Killing Gate instantly turned into powder.

"Demon Breaker...... Good sword, good sword" Chu Zun laughed, took the long sword in Gu Chen's hand and waved it, "Why am I so unfamiliar with this sword, it seems that there is your consciousness in this sword body?" ”

"What I cultivate is the body of the ultimate Five Elements Xuan Body, which is the same as the sacrificial thing of the Five Elements Supporting Heaven Pillar, after the Five Elements Supporting Heaven Pillar was accepted by me, it was completely integrated with my Xuan Body, and when refining this Demon Breaking Sword, I integrated the Yuan Shen, Karmic Fire and Qing Hell Fire, so I did have a strong connection with myself" Gu Chen said.

"No, no...... This sword has a powerful evil aura, and there is a sense of foreboding, Gu Chen, why did you refine a magic sword? This can be known to be bad for you and its disadvantage," Chu Zun looked at Gu Chendao.

"Why do you say that," Gu Chen said puzzled.

"This sword is so powerful that anyone who uses this sword will definitely be eroded by the evil qi, slowly wear out their minds, and eventually become a puppet of this sword, and completely become a puppet of killing."

Gu Chen looked at Chu Zun and smiled, "Hahaha...... What is positive? What is evil? The sword was originally born for killing, and now I am forging a sword with my body, and it is supposed to get rid of the demons that have invaded my domain, so what? What about evil? I am only to protect the people I want to protect, with the sword to be righteous, with the sword to be evil, if I kill for the blood domain for the people I love is also an evil way, then I am willing to fall into the evil way, never be right"
