Soul searching, there are many restrictions, and the slightest carelessness may cause the other party's backlash, but with Ye Yu's cultivation at this moment, it is not difficult to use the Xuanyang method to run this technique, plus this person's primordial spirit is extremely weak, and there are not many obstacles to it, but afterwards, this person will definitely die.

A terrible scream came from Zhang Haiyun's mouth of the Yuan Shen, the soul searching technique is extremely domineering, one of the supernatural powers that hurt the heavens, this magic power is cast, if there is a physical body, the pain can still be smaller, but if it is directly cast on the Yuan Ying or the Yuan Shen, then the pain will be magnified several times.

Zhang Haiyun's scream slowly weakened, and after half a burnt incense, there was almost no sound, and his trace of Yuan Shen became almost transparent at this moment, and it would dissipate with the wind at any time.

Ye Yu raised his left hand, directly penetrated Zhang Qi's Yuan Shen, and stretched into the position of his dantian, and when he closed his hand, half a crystal appeared in his hand.

Ye Yu's face was thoughtful, and he completely sealed Zhang Haiyun's weak Yuan Shen in the wolf tooth knife, which was Ye Yu's sudden thought.

He had been thinking about how to increase the power of the wolf tooth knife, and when he looked at Zhang Haiyun's weak Yuan Shen, Ye Yu wanted to verify the idea in his heart, using the Yuan Shen as the weapon spirit of the wolf tooth knife, but its effectiveness and power will not be known until later.

After putting the wolf tooth knife into the Xuanhuang ring, Ye Yu's body moved, and after taking away the storage bag of the man in black, he didn't even look at the body of Zhang Haiyun.

"In this demon realm, there is such a mystery, no wonder the chief of the situation mentioned that if the foreign cultivators do not die, they will set off a bloody storm here. ”

"Ghost King Sect, I have a new grudge against you and an old grudge against you, and I will settle the account with you after I return to the Xuanwu Continent! I can practice several forbidden techniques of this Haiyun memory!"

Night Feather stepped on the Earth Walking Divine Sword, while consuming all the secrets discovered from Zhang Haiyun's sea of knowledge, the most strange thing for Night Feather was the 'Demon God City' recorded in Zhang Haiyun's memory.

From his memory, Ye Yu learned that Zhang Haiyun had unexpectedly arrived here a hundred years ago, but Zhang Haiyun had never entered the Demon God City, and only took the position of captain of the guard in Qinghe County.

What was even more surprising was another memory of Zhang Haiyun, that is, Zhang Haiyun was not called Zhang Haiyun but Chen Zhong.

It's just that Zhang Haiyun's memory of Chen Zhong is very messy, so Zhang Haiyun didn't use Chen Zhong's name, but used the new name given by his master, Zhang Haiyun.

It is said that if an alien cultivator wants to enter the Demon God City, he must hand over 1,000 medium-grade spirit stones, or he can take a magic weapon of the same value as a mortgage, which is a bit similar to a toll.

"Hmm, what are the secrets of Demon God City? Why is this Haiyun so special yearning for it in his memory, and also, this Haiyun still has special respect for the city lord of Demon God City?" Ye Yu frowned, everything in front of him was like this pitch-black space, shrouded in layers of fog, making people confused about the direction.

There are still some spirit stones for Ye Yu, and as for the thousand medium-grade spirit stones, there are none in Ye Yu's Xuanhuang Ring. However, there are dozens of high-grade spirit stones.

However, Ye Yu didn't plan to give the top-grade spirit stone to others so easily.

Slightly swept the black-clothed man's storage bag, Ye Yu found that there were some pills in the bottles and jars, as for the magic weapon, it was pitiful, but a type of index finger bone attracted him, this is a human index finger, maybe because of the relationship between too long ago, this finger bone is covered with traces of time.

The reason why Night Feather paid attention to this phalange, maybe it was because this phalanx bone was stored in a storage bag by Zhang Haiyun, according to Ye Yu's knowledge from Zhang Haiyun's memory, this phalanx bone was obtained by Zhang Haiyun in the Demon Realm, but the next memory made Ye Yu feel strange.

This finger bone was found by Zhang Haiyun thirty years ago by a river of fire, you must know that it is a flame equivalent to the true fire of Samadhi, and this finger bone is actually lying on his back in that Gobi without waves, which makes Zhang Haiyun think that he has picked up a treasure.

Unfortunately, no matter how much he explored, he could not know the mystery, but this phalanx bone was very hard, and there was no other use.

"Well, there's a river here, and it's a river formed entirely by Samadhi True Fire?" Night Feather muttered to herself, but since she had met the legendary Sky Swallowing Beast and gluttony, Night Feather wouldn't be too surprised by any strange things.

After putting that finger bone into his Xuanhuang ring, Ye Yu had his own thoughts, since this finger bone was so hard and comparable to a third-order magic weapon, then if it was used for refining, it would be tantamount to an excellent material, Ye Yu really didn't know how that Zhang Haiyun could put such a treasure and didn't know how to use it.

If Zhang Haiyun still had a remnant soul in this world, he would definitely sneer at Ye Yu's ignorance, you must know that if you want to refine a high-level magic weapon, you must have the Xuanhuo of the Supreme Strength and Yang, and you must have enough preparation, and even if that finger bone is practiced into a magic weapon, it is at most a flying knife.

Therefore, Zhang Haiyun did not waste time condensing the magic weapon, but stored it in a storage bag, but he didn't expect to meet the pervert of Ye Yu and end his life here.

"Hmm, Hua Qianmei, they are also in Qinghe County?" In Zhang Haiyun's memory, Ye Yu got Hua Qianmei's whereabouts, he didn't have many friends, Hua Qianmei gave him a good impression, and the first person he met in the demon world was actually his titular junior brother, Hua Qianmei.

After Ye Yu absorbed Zhang Haiyun's half of the magic crystal, he couldn't help but be interested in the forbidden method in his memory, and finally let him know what the man in black used at the beginning.

"Demon Transformation Skill!"

This is an extremely domineering law, if you practice to the fullest, then, as long as the mind moves, the aura around heaven and earth will be turned into layers of demonic energy, for the use of the caster, it is an extremely anti-heaven law.

Legend has it that when cultivating the legendary demon, then all living objects around the caster will be demonized into puppets and manipulated by the caster.

At that time, the Demon Sect Li Tian used the Demon Transformation Skill, and Ye Yu was extremely impressed by the Demon Transformation Skill at that time, but the power of his divine sense at that time was not strong enough, and Li Tian had signs of self-explosion at that time, so he missed the Demon Transformation Skill.

And Zhang Haiyun Xuanhai's half of the magic crystal was absorbed and converted by him in the past three years with this 'magic transformation skill', and this magic was still seen where he found the finger bone, and it was recorded on a parchment scroll at that time, but that parchment scroll was forcibly destroyed by Zhang Haiyun after he saw all the mental methods.

The more Night Feather looked, the more excited he became, this was a spell that was quite helpful to him, especially when the caster's spiritual power was insufficient, he could absorb the essence of all things for his own use.
