Now Zhang Yifan has several life-saving skills, and now he is sure to escape even if he encounters a monk in the early stage of Jindan, and under the great improvement in strength, he will naturally not be too afraid.

The cave was dim, and after Zhang Yifan took out a lighting auxiliary magic weapon, the entire cave suddenly became as bright as day, and Zhang Yifan looked at the cave.

The whole cave is not big, only a few zhang in size, and it is surrounded by a layer of yin rock, no wonder it can interfere with its divine sense. The so-called Yin Rock refers to some ordinary stones containing Yin Qi, which are difficult for the divine consciousness to invade, but they have no practical effect, and they will be broken when touched. Yin rocks generally only exist in extremely yin places, which are formed by the long-term erosion of rocks by yin qi.

There is a hole in the cave that leads straight down, the entrance is pitch black, very deep, and Zhang Yifan can't explore much with the illumination magic weapon.

He cautiously walked down towards the entrance of the cave, this underground passage seemed to spiral downward, and the four walls exuded a faint yin aura, a little gloomy and cold. After about a stick of incense, Zhang Yifan walked for nearly ten miles, and he estimated that he was two or three hundred zhang deep from the ground, which was very deep.

Zhang Yifan finally came to the end, and what came into view was a wide cave. The whole cave is very large, about the size of five or six miles in a radius, and about dozens of zhang high. And the whole cave roof is scattered with stones as bright as the moon, like stars, cold and bright.

In the middle of the cave, there is a strange tree that is nearly ten zhang high, the whole tree is bare, without the slightest leaf, and the tree is pitch black, the whole tree is full of yin, and those yin qi seems to be rich to the extreme, visible to the naked eye.

Where the strange tree is located is a yellow ground about four or five zhang square, which looks out of place with the black ground around it.

Zhang Yifan looked at it carefully, and he had the impression that he seemed to have seen trees and soil in some classic.

"Ghost Yin Tree! Huangquan Earth! Yes, it's these two Extreme Yin Attribute Spiritual Materials!" Zhang Yifan finally remembered that he had seen the description and introduction of these two spiritual materials in a classic book of refining materials, but the two spiritual materials in front of him seemed to be different from those in the classics.

It's just that what is described in the classics is that the generally naturally generated Huangquan soil is almost only a zhang Xu Fangyuan, and the ghost yin tree generated in the Huangquan soil can grow up to two or three zhang, which is already considered the extreme. So Zhang Yifan didn't recognize it for a while.

The Ghost Yin Tree and the Yellow Spring Soil are mutually regenerating spiritual materials, and generally there are Ghost Yin Tree seeds first, and then the Yellow Spring Soil will gradually be generated around the seeds. With the passage of time, after the Yellow Spring Soil is generated, it begins to give birth to Yin Qi, and it is not until the conditions are ripe that the Ghost Yin Seeds will sprout and grow through the soil until they grow into the Ghost Yin Tree.

The ghost yin wood in the heart of the ghost yin tree and the huangquan extreme yin soil refined from the yellow spring soil are the best materials for making the yin attribute magic weapon, which is very precious.

Zhang Yifan couldn't help but feel a fire in his heart, this opportunity is really not small.

Just when Zhang Yifan was about to step forward to check one or two, a sudden change occurred!

"Gah!"

A sharp and abnormal sound suddenly rushed straight into his head, making his eyes black and his mind suddenly lost!

The two wonderful lotus flowers in Zhang Yifan's mind made Zhang Yifan sober up instantly, and then he felt a hint of coolness behind him.

"Not good!" Zhang Yifan didn't think about it, and in an instant, he launched a Yin Thunder Escape, opened ten zhang away in a flash, and then crushed a Donkey Kong talisman, and at the same time sacrificed the Jin Yuangang Shield. Zhang Yifan's expression was extremely ugly, as if he was facing a great enemy.

At this time, he felt some faint pain in his back, and also felt a little cold, the inner armor magic weapon he was wearing had been pierced, and a hole nearly a foot long and about half an inch deep had been cut on his back, which looked terrifying, and the blood oozing from the wound was black, obviously poisoned.

If it weren't for the miraculous effect of the two wonderful lotuses just now, Zhang Yifan was instantly sober, plus he was wearing a top-grade inner armor magic weapon, his own body had become relatively powerful after several years of tempering, and Yin Lei Dun had cultivated to Xiaocheng's skillful use and reacted relatively quickly, maybe he would have been seriously injured even if he didn't die now.

When Zhang Yifan turned around, he didn't find anything, everything was normal, which was really weird and made him feel very tricky.

Zhang Yifan originally thought that with his strength, everything would become simpler, but he didn't expect that he almost died in the first battle, which made him a little speechless. Everything in this world is not as simple as he imagined, and the slightest carelessness will lead to disappearance.

He didn't know that he was suddenly attacked by something, and naturally he couldn't make a targeted counterattack, so he could only defend passively. Fortunately, from the attack he encountered just now, he probably knew that the thing that attacked him should not have reached the power of the Jindan stage, otherwise he would definitely not be spared from the sneak attack. This made him secretly relieved, if he really encountered the existence of the Jin Dan Period, he would not hesitate to turn around and flee.

As if in the endless confrontation waiting, Zhang Yifan kept thinking about the solution in his mind, and he remembered the rumors in the classics.

It is rumored that once the ghost yin tree matures, it will attract the yin spirits that have not dissipated within a hundred miles nearby, and the yin spirits will fight and devour each other, and after 7749 days, the final winning yin soul will rely on the ghost yin tree to survive, will not dissipate, and will gradually become stronger and eventually become a powerful ghost thing, named Huangquan Yin Ghost.

This rumor was only described as a few anecdotes in the classics at that time, and it was not confirmed, so Zhang Yifan just regarded it as an anecdote at that time and did not pay much attention to it.

At this time, Zhang Yifan really believed it when he thought about it, and only such ghosts had such a ghostly body, coming and going without a trace.

When the time for the Donkey Kong talisman on Zhang Yifan's body to dissipate, "Ga!" Another sharp scream sounded, but this time Zhang Yifan was on full alert, plus two wonderful lotus to protect his heart, he just felt a little nauseous in his heart, and he did not lose his mind.

However, he pretended to be affected, his body trembling slightly, and his eyes were closed. Sure enough, a black shadow struck Zhang Yifan behind him with an incomparably black and sharp claw.

This time, Zhang Yifan had already prepared, he was in a hurry, and Jin Yuangang's shield quickly became larger, blocking the attack of the pitch-black claws. The claw left a shallow scratch on the Jin Yuangang shield, Rao was so also made Zhang Yifan feel frightened, he knew the defensive power of the Jin Yuangang shield very well, and the power of this claw was really amazing.

Zhang Yifan really saw what the sneak attack on him looked like.

The thin pitch-black body, the extremely long limbs, except for the head is a little dull, the rest of the entire body is pitch black and shiny, and the two pitch-black eyes are steaming with pale yellow ghost fire, and the whole appearance looks really eerie and terrifying, making people's scalp tingle.

This is indeed a Huangquan Yin Ghost.

This time, the Huangquan Yin Ghost did not disappear, but kept staring at Zhang Yifan. Zhang Yifan secretly used his divine sense to detect the Yin Ghost Breath, and found that the Yin Ghost Breath was extremely powerful, and it seemed to be much stronger than the ordinary monks in the late stage of foundation building. This made him feel a lot of trouble, and secretly said that this Huangquan Yin Ghost was a bit tricky.

"Quack quack, finally a monk has come here, or a monk in the early stage of foundation building, so lucky. The little monk of the third layer of Qi refining that he devoured last time was really a little bad. As long as you devour your soul this time, the old man can really advance to the list of ghost generals, which is comparable to the realm of Jindan, and it is not in vain for the old man to cultivate the ghost path. When the time comes, the old man will cut that kid with a thousand knives, so that he can often suffer from devouring souls!"

This makes Zhang Yifan a little strange, there are words in the classics that ghost things are not in the realm of the legendary ghost king, and they can hardly understand human language.

"Who is Your Excellency? Zhang Yifan couldn't help but ask.

"Boy, the old man used to be just a low-level casual cultivator, and he didn't have much fame, so it wasn't worth mentioning. The old man sees that you have excellent magic weapons and quite a bearing, you seem to be from a sect, I don't know which sect it is?"

"Hmph! Your Excellency is a group of ghosts and ghosts, who will harm the people and indiscriminately hurt people's lives, and will give you a ride. Zhang Yifan felt that the Huangquan Yin Ghost seemed to be dragging time, and suddenly felt that it was not good, and then sacrificed a fierce golden gun to attack the Huangquan Yin Ghost.

"Quack, have you noticed? It's too late! Come out, old man's people!" the Huangquan Yin Ghost let out a terrible laugh, and then directly merged with the black ground, disappeared without a trace, and easily dodged Zhang Yifan's attack.

Then hundreds of corpses began to emerge from the entire cave floor, and they turned out to be fierce zombies. Among them, the leader is a three-headed zombie with a very powerful aura, and the bronze body is nearly a foot high, which is comparable to the bronze corpse of a monk in the foundation building period, and the bronze corpse in the middle is comparable to a monk in the middle stage of foundation building. The rest of the hundreds of zombies are black iron corpses that fill the entire cavern.

The exit when Zhang Yifan came had been blocked by dense iron corpses, and it turned out that the Huangquan Yin Ghost was talking to Zhang Yifan just to attract his attention, and secretly woke up the zombies buried in the ground, thus surrounding Zhang Yifan tightly.

After the two battles, the Huangquan Yin Ghost felt that the monk in front of him seemed to be very difficult, and he was a little afraid that he would escape, so that this place would be exposed, and he had not yet advanced to the ghost general, so he could not be exposed to the sun for a long time.

So with a little trick, the person in front of him was trapped, and he was a little proud in his heart, and he was also a little looking forward to refining the power of zombies.

He has been a ghost cultivator for so long, except for the booby-trap monk before, he has never met other monks, and he was only a little monk in the Qi refining period before his death, although he has seen a monk in the foundation building period, but he has never seen a monk in the foundation building period make a move, so he doesn't know much about it.

Although becoming a ghost cultivator made him greatly strengthened, and then secretly refining the zombies, especially the three bronze corpses, made him full of confidence, but he couldn't help but feel a trace of awe for the foundation building realm that he longed for before his death, so as soon as he made a move, it was a thunder method, so that the other party would never be spared.

Zhang Yifan felt that the appearance of these iron corpses in front of him was a little familiar, as if he had seen it somewhere, and at the same time, he felt a sense of crisis about the cunning shown by the Huangquan Yin Ghost.

Facing hundreds of iron corpses under the leadership of three bronze corpses comparable to those in the foundation building period, Zhang Yifan didn't dare to hold it up, and directly summoned Xiao Bai and Xiao Hei from the spirit beast bag.
