"And the trace that was swallowed up by the Divine Sword just now should be the true dragon blood purified from some kind of descendant demon beast, but it is relatively mixed, and the concentration is extremely low, so the power is so small!" said Mixed Yuanzi in a very regretful tone.

He was thinking, this was obviously because the other party's purification methods were too rough, and the level of the true dragon descendants was not enough, otherwise the purified true dragon blood would be of such great use that it would make him crazy in his heyday more than a thousand years ago!

Zhao Di was shocked when he heard this, the terrifying gray dragon was obviously summoned with this "True Dragon's Blood" as the core and used the secret art to refine it, and it was actually said that "the power is too small" in the mouth of the mixed yuanzi!

"Your god-killing sword is indeed a very powerful demon sect treasure, and even a trace of mixed true dragon blood can devour it! Mixed Yuanzi added.

"Hey, if it's the authentic supreme treasure of the Divine Slayer, the Demon Realm Blood Shadow Holy Ancestor's Immortal Drinking Sword, there will be no problem. It is rumored that the sword that drinks immortals can drink the blood of immortals, and it is comparable to the existence of true spirits such as true dragons of immortals, so it must be no problem. The Divine Sword is just an imitation, and it can actually devour a trace of impure true spirit blood, and the Drinking Immortal Sword is really powerful! It is worthy of being a more famous existence in the Xuantian Spirit Treasure. Thinking of this, Chao Yuanzi couldn't help but be fascinated, imagining how terrifying the rumored Drinking Immortal Sword was!

At the same time, he also wondered what kind of great divine power existed, which could imitate the Drinking Immortal Sword, and still retain a trace of its powerful power. And in this world, how can there be such a person and such a means!

"Senior, my god-killing sword has devoured the blood of the true dragon, will there be anything wrong!" Zhao Di asked sincerely, and he vaguely noticed a trace of abnormality.

"What's wrong with it, but it makes the power of this treasure a little stronger! But after all, this treasure is a treasure of the Demon Gate, if you are an ancient demon body or have cultivated ancient magic skills, you can give full play to the power of this treasure, and the higher the cultivation, the greater the power of the treasure. With your current cultivation situation, if you don't practice demonic skills, I'm afraid that within a year, you can use the Divine Sword three times at most, and you can't use it unscrupulously in a row, otherwise the demonic qi will enter the body, and even the Buddhist Sect Exercises will not be able to solve it!"

"I see, thank you seniors for your advice!" Zhao Di said, he noticed a trace of abnormality in his body, so he asked, it seems that in the recent period, he can't use this sword.

As for cultivating demonic skills to cooperate with this sword and exert the greater power of the god-killing sword, it is simply putting the cart before the horse, and the gains outweigh the losses, and Zhao Di will never consider it.

Although immortal cultivators have a long lifespan, in order to cultivate, time is also precious, so how can they spend a lot of time re-practicing the Demon Gate Exercises.

Zhao Di flew to the fainting young woman Hu Mei'er, and after a little investigation, he found that this demon had been continuously attacked by ghost howls and dragon chanting, and his mind was seriously damaged.

At the moment, he ignored this woman for the time being, but looked at the gray water spring not far away.

"Senior, what is the origin of this spring water, when I was chasing and killing the ghost baby just now, I probed part of my divine consciousness into the spring water, and I was swallowed up by this spring water. Zhao Di remembered the scene just now, and he was still scared in his heart.

Mixed Yuanzi frowned and said, "I have long felt that this spring is unusual, it can continuously produce such a dense yin qi, and engulf the divine sense, it is really extraordinary. I even guessed that this was the rumored water of the River Styx!"

"The water of the River Styx, is it impossible!" Zhao Di exclaimed, "It is rumored that the River Styx is the dividing line of the Netherworld and the Ghost Realm, and the Styx River is where the breath of living beings is isolated, how can there be a spring of the Styx here, is it not possible to build the Netherworld and the Ghost Realm below this spring!"

"I don't think it's like it, but I can't think of any other explanation for a while. Mixed Yuanzi shook his head and said, then snorted lightly, "Actually, if you want to confirm whether it is the water of the River Styx, it is very simple, you only need to throw these two demons into the water and see what happened to them." ”

Legend has it that the waters of the River Styx are cut off from life, and whether they are living creatures or fresh corpses, they will turn into white bones if they are contaminated in the slightest.

"No need. Zhao Di smiled slightly, "Whether this is the water of the River Styx or not is not very important. What's more, this person brought me here, why should I be willing to risk the birth of demons and not keep my word, besides, this person has other important uses for me. ”

Zhao Di pointed to the young woman and said.

"Well, Daoyou is really a trustworthy person, hehe, I cooperated with you, and I didn't choose the wrong person!" said with a smile.

"Senior, what kind of treasure is this thing, the predecessor just repeatedly told me not to destroy this treasure. Zhao said, summoning the Ice Wind Jiao, who gently spit out a blood-red eyeball, which was the Xuanyin Ghost Eye.

Under Zhao Di's order, Ice Wind Jiao immediately went to various places in the cave and recalled all thirteen invisible flying needles.

These thirteen flying needles, the cultivation time of the Ice Wind Jiao is still short, and it is not possible to send and receive them freely, it is easy to squirt, but it is difficult to take them back. At least it will have to be roasted in the body of the Ice Wind Jiao for more than ten years before it can be recovered as you like.

"Hehe, the origin of this Xuanyin ghost's purpose, I'm afraid it will scare you if you say it!" Mixed Yuanzi stared intently at the terrifying blood-red eyes in Zhao Di's hand, and said excitedly, "Have you ever heard that there is an innate spirit body called Yin Yang Pupil." ”

"Yin Yang Pupil! Of course I've heard of it, isn't that the most powerful kind of spiritual eye in the world of cultivating immortals? It is rumored that a monk with a yin-yang pupil can cultivate the yin-yang supernatural power, and in just the blink of an eye, he can kill the enemy invisibly!" Zhao Di said excitedly, he knew that this extremely powerful yin-yang pupil of Chao Yuanzi at this time must have a deep meaning.

"That's right! But the monks who are born with the Yin and Yang Pupil Spiritual Purpose are extremely rare, and there are fewer monks than the Heavenly Spirit Root! However, I have a secret method, which can be used to cultivate some of the Yin and Yang Spiritual Powers with the help of some treasures. Mixed Yuanzi nodded and said. Obviously, the treasure he mentioned in his mouth included this Xuanyin Ghost Eye.

"Did the predecessor say that you can use this Xuanyin Ghost Eye to cultivate the Yin and Yang Divine Powers?" Zhao Di said in surprise.

He had seen the record of Yin and Yang Divine Power in ancient books, and it was rumored that this divine power was cultivated to a very high place, and it could kill opponents of the same level in the blink of an eye, even if it was destroyed against slightly higher opponents, it also had the upper hand.

"It's indeed feasible, but if you want to cultivate Yin and Yang with the help of external forces, you must have two extremely familiar spiritual eyes, one Yang and one Yin, and now the Xuanyin Ghost Eye in your hand can be used as an Extreme Yin Spiritual Eye, temporarily cultivating part of the supernatural power, but it is also enough to become a big help for you in the future!" In the tone of the mixed Yuanzi, there was no lack of envy and jealousy, you must know that this kind of spiritual vision is extremely rare, he has practiced for many years, and this is also the first time he has seen the spiritual eyes of the extreme yin or extreme yang.

"Thank you seniors for your advice! I don't know what conditions my predecessors have, I am willing to guide me to cultivate this magical power, and I will try my best to meet it in the future. Zhao Di said happily, and rarely wrote all the joy on his face.

"Yes, indeed. This magical secret method is not easy to obtain, and I naturally can't give it to Daoyou for nothing, and give detailed guidance throughout the process. My own conditions are the secret of the Nether Scepter!" Mixed Yuanzi was prepared and made his goal clear.

"Nether Scepter! Hehe, the senior really thought of it with him!"

The corners of Zhao Di's mouth curled, and he smiled mysteriously.

He paused for a moment, and said, "That's right! This Netherworld Scepter, which actually allows that ghost girl to instantly devour the body of ten thousand ghosts, is really mysterious, and I also want to know what the origin of this Netherworld Scepter is!"

Mixed Yuanzi nodded, and said approvingly: "Daoyou said at once that the key is above, although the spell is powerful, but it consumes great spiritual power, and what is more disadvantageous is that it takes a long time, and it is extremely difficult to appear in the ever-changing monk fighting method, throughout the ages, I don't know how many powerful people who cultivate immortals, in vain to shorten the training time of the spell, but the effect is not obvious enough, at most, the spell that was originally sacrificed and refined in one hour is shortened to be completed in a small half an hour, but it can not be used in the fighting method. ”

"Now that I have personally seen someone who can use spells instantly, the horror in my heart is really extraordinary, and I also want to find out how this ghost girl did it, and this reason is obviously on this Nether Scepter!" Mixed Yuanzi said what he thought in his heart, which coincided with Zhao Di.

Zhao nodded silently, and as soon as his palm was stretched, there was an additional square inch size ash box in the palm of his hand, which was the special storage method for ghost cultivation - the yin niche.

Zhao Di used his spiritual power to try a little, and sure enough, he found that he couldn't use this thing.

"Youlan, see if you can open this. Zhao Di said softly.

"Yes, master. Youlan appeared, and a yin qi popped out of her hand, hitting the yin niche, easily opening the object, and pouring out a bunch of all kinds of treasures.

Zhao Di held one of the two-foot-long black jade scepters in his hand and carefully investigated it.

The yin qi is extremely heavy, the texture is hard, the luster is bright, and it is indeed made of Xuanyin jade.

Upon closer inspection, the ball at the top of the Nether Scepter was covered with extremely complex patterns, some of which looked like spells, and some of which looked like runes on high-level runes.

There is no doubt that the refining technique of the entire Netherworld Scepter is very superb, and the texture is extremely complex, Zhao Di only feels that the difficulty of refining this thing is probably far more than his natal magic weapon, the Dream Glass Sword
