The injuries on the black tiger's body became more and more serious, and after a few more roars, the black tiger let out several screams similar to wails, and after a short while, a small black head poked out of a cave not far behind the black tiger.

The black tiger let out a few more rapid cries, followed by a few successive wails. Lin Feng couldn't understand what the little black tiger meant, but he seemed to hear a thick reluctance from the wail.

The tiger cub finally ran out of the cave, and after looking at the black tiger a few more times, he turned around and ran towards the forest. The three-tailed spirit fox wanted to pursue, but was desperately stopped by the black tiger. Lin Feng didn't know what he wanted to do, so he followed the tiger cub from a distance.

It wasn't long before a black tiger roared from behind. It didn't take long for Lin Feng to hear the movement of creatures running wildly behind him. The tiger cub also heard it, and rushed into a cave not far away. Fox spirit animals are often more sensitive to smells, and it will be time to find this cave in a while, and there will be almost no life if it is blocked in the cave. Lin Feng's mind was hot, and he also rushed into the cave, thinking of quickly taking the black tiger out to find another direction to escape. It wasn't until he heard the violent movement in the passage behind him that Lin Feng reacted, and now even he was blocked in the cave.

The little tiger didn't run slowly in the cave, and Lin Feng didn't catch up with the little tiger for a long time. After a while, Lin Feng suddenly heard the aggrieved cry of the little black tiger not far in front of him, Lin Feng sped up his pace and turned the corner, and finally came to the end of the cave, and at this time, the little black tiger was leaning against the innermost wall and shivering.

Now it's useless to complain, Lin Feng turned his back to the little black tiger, took out the bursting rune paper, and sacrificed the Streamer Flying Feather Sword to prepare for battle.

In the distance, the movement created by the spirit fox in the cave was getting closer and closer, but Lin Feng was getting calmer and calmer. Maybe you don't need to die, after all, this three-tailed spirit fox just completed a death battle with the black tiger, and the black tiger's dying counterattack may have caused a lot of damage to the three-tailed spirit fox, and his current combat strength is not an exaggeration to call it the peak of the Jindan period.

Just when Lin Feng was full of energy and was about to deal with the three-tailed spirit fox with the strength of the Yuan Infant Stage, Lin Feng suddenly noticed that the cave wall not far away beside him seemed to be a little different. There is a small patch of moss on the wall that is much lighter than the others, and when you look closely, it looks like many palm prints are stacked on top of each other. Lin Feng suddenly remembered something that Lin Wanshan had told him.

In fact, the forces of the cultivation realm do not have a strong restraint on the monks under them, and it often happens that they go out to practice for dozens or hundreds of years. If you encounter it, you may have to make a breakthrough how far away from the sect. When some monks are about to break through, or when they are about to sit down, they will open a cave in some hidden places in the deep mountains and old forests. If you can find the cave house opened by the senior master before the sitting, it will be a good opportunity for the monk.

And the place where there seems to be a lot of palm prints on it is very likely to be the place where the opening mechanism of this cave is located.

Lin Feng hurriedly came to the wall, put his palm on it, and a stream of mana was quickly poured into it. The mana transported to the wall did not dissipate, but was concentrated on the small piece near the palm print, and Lin Feng knew that he was very likely to make the right bet.

With a roar, the cave wall not far behind the little black tiger began to shake. The little black tiger was taken aback, but because Lin Feng was on the side of the passage, he didn't dare to run in the direction of Lin Feng, but just turned around and paid attention to the movement behind him with a nervous face.

The walls of the cave gradually rose, slowly revealing the huge space behind it. The little black tiger lowered his head and hurriedly chased after him, and Lin Feng also followed. Not far from the entrance of the cave, there was another shape of multiple palm prints stacked on top of each other. Lin Feng ran to him and hurriedly injected mana, and the rising boulder stopped rising and began to move downward. Lin Feng noticed through the gap that the three-tailed spirit fox had already arrived, but seeing that the space under the cave wall was getting smaller and smaller, the three-tailed spirit fox finally did not squeeze over directly.

The cave was closed, and through the boulder, Lin Feng heard a huge movement outside. But the cave was originally used to prevent external interference, and the layer of boulders outside the cave was definitely not a simple stone, which could be broken so easily.

There was a metal stick inserted into the wall near the access switch, and Lin Feng pulled it out vigorously. It's called the Broken Dragon Pillar, and after taking out the Broken Dragon Pillar, the cave can only be opened from the inside.

The top of the passage was inlaid with several spirit stones that emitted a dim yellow light, and Lin Feng walked all the way along the passage, and soon came to a place similar to a hall. Six passages extended from the hall, except for the passage in and out of Lin Feng, all of the other five passages were written with a large character written in ancient seal script.

"Dan", "Instrument", "Fu", "Medicine", "Mine". Lin Feng knew that he had found a cave mansion left over from his predecessor's instrument cultivation.

No one has been in the cave for some years, there is a thick layer of dust on the ground, looking at the cute footprints on the ground, Lin Feng knows that the little black tiger should have run all the way into the passage with the word "medicine" written on it.

As soon as he walked into the channel of the word "medicine", Lin Feng saw the little black tiger. After all, it was just a young beast, and now it had almost forgotten for a moment what the adult black tiger might be suffering from at the moment. After feeling the spiritual power fluctuations behind the stone gate at the end of the passage, he jumped and wanted to rush over, but after going back and forth for a long time, he finally failed to open the stone door. When Lin Feng walked into the passage, he saw the little black tiger running around in front of the anxious stone gate.

Lin Feng smiled unconsciously and walked towards the stone gate. The little black tiger was a little recognized, and when he saw Lin Feng coming, he quickly hid aside. When Lin Feng came to the vicinity of the stone gate, the little black tiger rushed past Lin Feng, and after running out, he turned his head again and looked at Lin Feng with a tangled expression. Lin Feng found the bolt of the door, and as soon as he pulled the mana, he pulled the stone door open.

As far as the eye can see, it is leaning against the wall, and it is not a small row of medicine racks. Lin Feng looked left and right, and found two pieces of the Yellow Rank Top-grade Medicinal Herb Cold Smoke Fruit that could only grow in certain cold environments.

After Lin Feng entered the medicine cave, the little black tiger took two steps forward and came to the entrance of the cave, Lin Feng was in the cave, it didn't dare to enter the cave. However, after seeing the two pieces of cold smoke fruit, the little black tiger immediately showed a coveted face. Lin Feng was amused by the little black tiger's cute expression again, came to the medicine field, picked a few cold smoke fruits and threw them at the little black tiger. After that, Lin Feng came to the medicine shelf, the medicinal materials stored in the transparent jade box.

Xuanyang fruit, melting spirit grass, three-color peony, yin silkworm branches, ....... The medicinal materials on this medicine shelf are generally above the Xuan Rank. Xuan-level medicinal materials can generally be used as the main material of Xuan-level pills, and if you can refine Xuan-level pills, the master grade of this cave mansion must not be low. Normally, if there is no alien fire, if you can refine the Xuan-level pill during the merger period, then this Dan Xiu's alchemy talent is already quite good.

Judging from the dust in the cave, no one has walked around this cave for a long time. And the broken dragon pillar at the entrance was not taken out, which proves that the owner of the cave should have left the cave. I think that the owner of the cave must have encountered an accident after leaving the cave for the last time, otherwise, it would be impossible to let so many things stay in the cave mansion and not come back to take these things.

Lin Feng went to several other caves to take a look, the "mine" word cave stored a lot of Xuanjie, Huangjie spirit ore, "Fu" word cave, in addition to some rune paper runes that have not yet been engraved, there are also a lot of classics related to the rune seal. The cave with the word "Dan" and the cave with the word "instrument" should be the place where the owner of the cave refines the pill and refines the weapon, in addition to their respective related classics, there is a one-meter-square fire spirit jade in the center of these two caves. Fire spirit jade is a kind of reserve spirit ore commonly used in instrument cultivation, instrument cultivation can quickly extract fire attribute heaven and earth spiritual power from this spirit ore, and sit on top of the fire spirit jade when refining or refining, which can alleviate the problem of lack of follow-up of natal true fire to a certain extent.

Except for those classics, pills, and two pieces of fire spirit jade, there were no finished pills and finished magic weapons in these two caves, presumably the owner of this cave had all been included in the meson space before leaving.

Anyway, I wasn't sure if the three-tailed spirit fox really left, and this cave was indeed a good place to stay, so Lin Feng finally decided to retreat in this cave for a while.

The little tiger stayed in the cave for a while, and after discovering that Lin Feng had no desire to hurt it, he slowly became less recognizable. After a while, he became more and more familiar with Lin Feng, and every time he saw Lin Feng wake up from his meditation, he quickly ran to Lin Feng and rubbed Lin Feng with his neck. Lin Feng knew what it meant, so he picked a few fresh cold smoke fruits from the cave of the word "medicine" and threw them to this cute little guy.

All five caves have a stone door on the outside that is pulled from the outside and pushed from the inside. The little guy can open the stone door from the inside by brute force, but once it gets stuck outside, it is helpless. A few times when Lin Feng entered the "medicine" hole to pick fresh fruits for it, it was lying in the "medicine" hole, but it could also eat happily. But not long after eating, the little guy couldn't bear the loneliness and ran out of the hole in the word "medicine". If Lin Feng cultivates in the hall, it would be fine, but if Lin Feng entered a few other caves, the little guy would really be called Heaven and Earth Spirit. And at this time, the little guy just wanted to go back to the "medicine" word hole, and it couldn't get in again.

Later, the little guy finally figured it out, and from then on he would never leave Lin Feng, and he would go wherever Lin Feng went. Lin Feng didn't have a breakthrough, and it usually only took a day or two to settle down, and since the little guy decided to stay with Lin Feng an inch, the little guy no longer had to worry about the loneliness of being alone in a place without Hanyan Fruit to eat.

Lin Feng was also familiar with the existence of this little guy, and gave the little guy the name "Little Black", and slowly, the little tiger also recognized Lin Feng's name for it.
