Fortunately, he had already memorized the map of the Yin Spirit Cave carefully before he came, and the entrance was originally in the north, but he deliberately ran to the west, and deliberately ran very slowly, which made the two of them feel contemptuous.

There was a col on the west side of the map, and when he ran to that col, he jumped in, and the two of them thought he had disappeared out of thin air, and of course they would come after him by surprise, and he was pretending to poop, and then poured a few drops of the pee of the smelly hogmon.

But he never expected that the urine of this fox pig beast would stink like this, and when he got close, a smell rushed directly to his mouth and nose, choking him with tears, unable to breathe, and almost fainted.

No wonder the little thin man who sold the goods frowned when he talked about the urine of this fox pig beast, it seemed that he must have smelled it.

Qin Xin immediately held his breath, closed the bottle containing the urine of the fox pig beast, and then wiped his tears without caring about the nausea, and rushed directly in the direction of the Yin Spirit Cave.

It was different when he ran with all his might, and with a flip of his hand, a light body talisman slapped on himself, and then he used his internal strength and family heirloom light power, shot out like a sharp arrow, and rushed towards the direction of the entrance of the Yin Spirit Cave.

Just when Qin Xin was running wildly, Senior Brother An was fanning his nose with his hand at this time, his brows were furrowed, and the fat man was vomiting endlessly next to him, even spitting out bile.

While spitting back, he cursed: "Grandma's, this kid ...... Have you eaten poop...... How can you pull out such a stinky......"

Senior Brother An kept covering his nose, and when the fat man was almost vomiting, he said with palpitations: "This kid's should be finished, right?"

"Almost, isn't ......it? Are you going to take a look?" The fat man's face turned green, and when he heard Senior Brother An mention it, he couldn't help retching a few times.

"Forget it, let's wait, the smell won't go away for a while. Senior Brother An shook his head, the smell just now made him really unforgettable for life, and he really couldn't muster up the courage to smell it again.

"That's it, wait a minute, this kid runs at the same speed as a turtle, and even if he runs, he won't be able to run far. The fat man hurriedly chimed in, saying that if he was allowed to smell that smell again, he would definitely vomit again.

Half an hour later, the two of them mustered up the courage to cover their noses and came to the place where Qin Xin had squatted just now.

"Oops, this kid actually. When the fat man saw that there was not even a figure around, he said angrily.

"Interesting, looking at this kid's loyal face, I didn't expect it to be a slippery head, and he dared to play tricks. Senior Brother An pointed to the place where Qin Xin had squatted just now, and there were no "relics" there at all.

"Damn, what did that smell like just now, it stinks to death. The fat man said in disbelief

"No matter what it smelled just now, anyway, we let this kid play it, it seems that he did it on purpose to go in the wrong direction, damn, it's a shame to let a mortal play it, let's chase it." Senior Brother An said hatefully, but he felt that since the other party had such a scheming, most of the two of them would not be able to catch up.

Senior Brother An was right, Qin Xin had already arrived at the entrance of the Yin Spirit Cave by now.

Looking up, this entrance is one or twenty zhang wide, and it is almost the time of winter, so the weather is already very cold, but just like this, he can still clearly feel that there are bursts of cold air at the entrance of the cave that are cooler than the outside.

This kind of cold air made him feel a sense of déjà vu, and he figured it out after a little thought, that's right, it was the cold qi emitted by the Nine Leaf Ice Lotus, and it was this kind of cold feeling when Wei Huaichun opened the jade box for the first time.

He touched the jade box in his arms, and without too much hesitation, he went directly into the cave, he didn't want to wait for the fat and thin two to catch up just now.

After entering the cave, there are passages, which lead in all directions, and as soon as you enter, you will feel the wind gusting and the cold air is pressing.

Ordinary people are naturally afraid of the dark and the unknown, just like when he first awakens his spiritual sense, he feels that when someone is observing him with his divine sense, he does not know what it is, and he feels creepy.

But now every monk will naturally scan each other with their divine senses when they meet, and they know what is going on, so they don't feel as terrible as they did at the beginning.

In the pitch-black cavern, it was the same, making him feel inexplicable fear and nervousness, and he slowly adapted to the discomfort caused by the darkness, because the Sun Stone was a disposable item, so he wanted to save as much as possible.

But he didn't go far, and after only a few forks, he felt that the pitch black was out of sight, and he couldn't make out the intersection.

In desperation, he could only take out the Burning Sun Stone from the storage bag, remove the sealing charm on the Burning Sun Stone, and a bright light emanated from the Burning Sun Stone, and he estimated that the Burning Sun Stone was also weakened a little, because he could only rely on this faint light to see three feet away.

He has been practicing internal strength all year round, although the immortal cultivation world calls it turbidity, but the internal strength he practiced has already had a certain heat, and it has long been cold and hot in the secular world, but in the Yin Spirit Cave, he can still feel the slightest cold qi drilling straight into his body.

He took out the water and fire robe issued by the mountain gate from the storage bag, and sure enough, it really had some warmth effect, and the chill was greatly reduced after wearing it, he first found a cave and stayed for a while, and then slowly walked for a distance, and finally he was sure that there was really nothing wrong with him in the Yin Spirit Cave, so he put his mind at ease.

When he first entered the cave, he tried his divine sense, and sure enough, his divine consciousness was also greatly compressed, and the divine consciousness that could already be separated from his body by more than a foot was only two feet away from his body here.

He took a few deep breaths and took out the map of the Yin Spirit Cave, carefully compared his positions, and then walked in the chosen direction towards the depths of the cave.

Don't look at him as if he walked very casually, in fact, this path was carefully selected by him after a long time, careful consideration and comparison.

The reason why he chose this road is because the map indicates that no one has ever encountered a ghost on this road, and he mainly focuses on safety this time.

It's just that although this road is very safe, it takes more than ten days to walk before you can go to some places that no one has explored before to find Yin Blood Crystals.

The longer the monk stays, the greater the mana damage will be, and here he doesn't have the slightest mana, so his advantage is that he is not afraid to stay for a long time, he must save his life this time, and he has to collect enough Yin Blood Crystals and earn enough spirit stones, so he has made up his mind to fight a protracted battle, so he is not in a hurry.

The road in the cave was very complicated, and there were many forks, and although he had a good memory, he still had to take out the map from time to time and carefully look at and compare it, for fear of taking the wrong path.

He doesn't know the time here, everything can only be based on feeling, and when he feels tired, he will find a place to take a nap, of course, he also sleeps with one eye open and one eye closed, and he will wake up immediately at the slightest movement.

Once, when he was sleeping, he heard a long sigh, which frightened him so much that he couldn't tell whether it was a man or a monster.

Because he walked more cautiously, he walked very slowly, and the road that was expected to take more than ten days gave him the feeling that he had walked for more than twenty days.

In this dark place, he couldn't say how many days had passed, so he could only judge and estimate by feeling.

The first method is to estimate from the time of eating Bigu that one pill of Bigu Dan can make him go without eating for about half a month, he ate one pill in Yinling Town, and he ate another pill a few days ago, so it should be more than 20 days, but Bigu Dan also varies from person to person, so it is not very accurate.

The second method is to look at the light emitted by the Sun Stone, generally speaking, a Sun Stone can be used for more than a month, but in this weakened case, he doesn't know if it can be used for a month, and now from the faint light of the Sun Stone, it is almost more than 20 days.

Fortunately, he really didn't encounter any Yin Spirit Ghosts along the way, of course, he walked over on the way, and he didn't see any Yin Blood Crystal.

After so many days, day and night, he now came to a cave the size of three zhang, after careful comparison, this three-zhang cave is the last place explored by this road.

He looked around, and in the empty cavern, in addition to the intersection from which he came, there were four passages leading to other places, all of which were shown on the map, but they were all marked unexplored.

He pondered for a while, rested in the cave for a while, drank some of the small he had brought, then took out the map, made a mark on the leftmost passage on the map, and searched all the way along the passage.

His luck was very bad, he walked for another two days, and he didn't find a single Yin Blood Crystal, and when he was a little disheartened, he began to wonder if he had chosen the wrong path, and he finally found a blood-red stone the size of a crystal clear egg on the wall of a passage.

He was so excited that he almost wanted to cheer, but upon careful identification, the stone was as red as blood, and it exuded a chill that was colder than that of a cave, and it was exactly the same as the picture in the illustrated book.

After determining that this was the so-called Yin Blood Crystal, he was ecstatic, took out the four-hook hoe, and carefully pried the Yin Blood Crystal off the wall.

Qin Xin actually felt that his hands were trembling a little when he was prying, and he scolded a few times: "It's useless."

This is the first time to harvest Yin Blood Crystal in more than 20 days, it should be normal for him to be a little excited, this Yin Blood Crystal is all his hope, although the Yin Blood Crystal is still a little frozen in his hand, but he still doesn't care, he keeps playing with this Yin Blood Crystal in his hand.

With this Yin Blood Crystal, his confidence increased a lot.

Maybe it was this first Yin Blood Crystal that brought luck, in the next few days, he could find several Yin Blood Crystals every day, and in just a few days, he found twelve Yin Blood Crystals.

Qin Xin secretly calculated in his heart, each Yin Blood Crystal could be sold for thirty spirit stones, and twelve could be three hundred and sixty spirit stones, he could not only pay off Lu Feng's spirit stones, but also be rich, he was really not busy in vain, he wanted to laugh when he thought of the Yin Blood Crystal in the Yin Spirit Bag.
