Rubbing the cave slave order, there is an inexplicable emotion welling up in my heart, it is cordial, it is worried and there is a trace of doubt. Motoo shook his head vigorously, trying to calm down, he gave up his divine defenses and let the information in the token flood into his body.

An hour later, Motoo had figured out the past and future lives of this brown salt grotto.

About 20,000 years ago, a pigeon took a nameless branch and inserted it shallowly on the white sand beach. Although the white sand beach is barren, it is always close to the white sand city, so it was not long before a young immortal cultivator discovered the giant tree, and realized that the reason why this giant tree grew here was because the underground was full of spiritual energy, and it was a good place to cultivate. As a result, the immortal cultivator not only had the idea of occupying the magpie's nest, but also planned to forge the giant tree into his own spiritual weapon. He swung his sword and cut down the trunk of a tree on the ground, but what he didn't expect was that the ground shook and a hole appeared. So the immortal cultivators went deep into the ground from the entrance and discovered the existence of the brown salt cave.

In fact, that tree branch originally had a great origin, and after a hundred years of cultivation, the tree spirit had reached the cultivation of the Gathering Spirit Realm that could transform into a human form. The Immortal Cultivator's cutting off the trunk of the giant tree did not harm its essence, it deliberately showed that the entrance of the cave was actually intended to lure the Immortal Cultivator into the tunnel and strangle him.

However, when the immortal cultivator actually entered the tunnel, the tree spirit felt emotional, and transformed into a young woman and appeared in front of the immortal cultivator. The two fell in love at first sight and became good fellow practitioners.

The tree spirit is named Elm Rhino, the Qingshan Wood Clan. The young immortal cultivator is called the abandoned scale, the scale tribe in the sea.

The two of them have been cultivating in the Brown Salt Cave for a hundred years, and they both reached the Bone Refining Realm.

However, one day, he abandoned the scales and went out to practice, but he never returned. The Brown Salt Grotto fell silent again, and the elm rhino was born of love and hatred, so he deliberately exposed a hole to leak the aura, attracting immortal cultivators to enter the Brown Salt Grotto, and detaining them as cave slaves to replace the abandoned scales. But the cave slave is not abandoned after all, there is always a time when he is bored, and every time at this time, the elm rhino kills the cave slave to find a new candidate.

So the entrance of the cave reappeared on the white sand beach, and the immortal cultivators from all walks of life who did not know the details followed the trail, and the elm rhino would choose a new cave slave to accompany him.

Until one day Yu Xi broke through the Soul Condensing Realm and left, she set the rules for her Brown Salt Cave, that is, every ten years, the entrance of the cave would be opened, and after the immortal cultivators entered the Brown Salt Cave, one person would be trapped in it and become a cave slave, unable to leave for eternity, while the others would be rumored out.

When the next time the entrance of the cave is opened, new immortal cultivators will enter it, and they will either kill the cave slaves to obtain the relics, or they will be killed by the cave slaves and become a handful of loess in the brown salt cave. In any case, the Brown Salt Cave will always keep a cave slave waiting for the cave to be reopened ten years later.

This cave slave token also records the cultivation process of each cave slave, Yuan Wei learned that the cave slave before him was called Black Stone, which was originally a stone with a soul, and it took thousands of years of cultivation to have the cultivation of the Gathering Spirit Realm, and he was inadvertently detained as a cave slave. However, Heishi was smart and decisive, regarded cultivation as fun, and regarded the opening of the cave entrance every ten years as an experience, and even resisted the attacks of ten immortal cultivators, thus reaching the bone refining realm. If it weren't for the Haoyang Hunter Gu Old Lady who inadvertently broke in, it is estimated that he would have been able to cultivate here for another ten years.

Yuan Wei knew that the reason why Heishi was able to advance to the Bone Refining Realm, in addition to his own efforts, another important reason was that the tree spirit elm rhino had already left, leaving only a trace of soul in the Brown Salt Cave to maintain the rules of opening and closing the Brown Salt Cave. Moreover, if Blackstone is given enough time, he will most likely break through the Soul Condensation Realm and thus break the rules set by the Elm Rhino and leave the Brown Salt Cave!

Yuan Wei took the token into his arms, and looked up to find that there were more than a dozen Gathering Spirit Realm Double Sword Mantis Ji gathered in front of him at some point, and the leader was naturally disturbing the dream.

Disturbing Dream leaned forward with his towering chest, "Brother, our sisters in this tunnel are all here, what do you want to do with them?"

The Twin Blade Mantis looked at Motoo, and that gaze was a little complicated. Whether it is the Twin Blade Mantis, the Drill Mountain Walker, the Red Centipede, the Turtle and the Enchanting Rabbit, these creatures bred in the Brown Salt Cave are ignored by the Elm Rhino to a certain extent, but they are enslaved by each of the cave slaves, and the cave slave token is a mountain that presses on them, making them unable to resist at all. Especially for Heishi, what he liked most at the beginning was to swallow spirit beasts alive, so as to improve his cultivation.

Motao knew everything from the token, but he didn't have a hobby in this area at all. He just waved them to clean up the broken hall, and limped down the tunnel to the atrium where the tree spirit elm body was.

"Brother, you're walking too slowly, why don't you come on my back and I'll carry you?"

Yuan Wei couldn't help but glance sideways at the delicate and weird back, naturally refused to climb on it, he turned into a Xuanhu with a roar and rushed away. Disturbing Dream covered his mouth and smiled, spreading his long legs and chasing after him.

The middle hall is where the elm rhino and the abandoned scales used to practice.

Yuanwei rubbed the jade body of the elm rhinoceros, this huge tree merged with the palm salt grotto, its powerful and developed root system is the area covered by the palm salt grotto, it is these dragon-like roots that penetrate into the ground to detain the aura between heaven and earth and continuously transport it. Yuan Wei suddenly thought of the Lingering Valley, and he didn't know what method Chang Xiang used to detain the aura there and thus become his own cultivation holy land.

Yuan Wei paced back and forth, and finally he stood in the place where Gu Sui'er almost went mad, scattered his divine sense, and tried to absorb the spiritual power here.

Ten years, he only has ten years, if there is another Bone Refining Realm immortal cultivator like Mrs. Gu after ten years, he will definitely be killed. And during these ten years, if he cultivated to the Bone Refining Realm, he would have more self-preservation abilities.

Motoo didn't know that his move had broken through the limits of previous cave slaves. In the past, the cave slaves never dared to spend more than a stick of incense in this atrium after obtaining the cave slave token, because there was abundant spiritual power here, but there was also a kind of coercion of master and servant. Therefore, they would rather stay in the outer hall at the outer end of the tunnel to cultivate.

Standing in the tunnel in a daze, she never thought that Yuanwei would cultivate in the middle hall, but Yuanwei stood there quietly, maintaining the same posture for a month.

"Is my brother a cave slave, why does it give me the feeling of a cave master?"

A month later, Motoo stopped from cultivating. Although his body was untouched, his divine sense had already explored all the ranges that the roots of the giant tree could reach, so he was already familiar with everything here. If he followed this cultivation method, he would be able to maintain the speed of one day a year, and before the next ten years came, he would almost be able to be promoted to the Bone Refining Realm. This is already an extremely astonishing cultivation speed. You must know that it took a hundred years for Blackstone to reach this state.

However, Yuan Wei was not satisfied, and he suddenly remembered one of Heishi's cultivation methods, which was to devour the various spirit insects and spirit beasts in the Palm Salt Cave alive and fulfill himself by depriving them of their cultivation results. If this method is adopted, Yuan Wei is confident that he will be able to get a faster cultivation speed. Looking at the Dream and the tunnel she was in again, Motoo's eyes flashed with a scarlet light.

The originally crumbling dream suddenly became cold, like a basin of ice water poured down from her head, she looked around excitedly, Yuanwei's eyes full of desire fell into her eyes, and the dream couldn't help but take a few steps back, and asked tremblingly: "Brother, what's wrong with you?"

Yuan Wei suddenly woke up, and a wave of shame welled up in his heart. He has longed for family affection since he was a child, and the sound of his younger brother who disturbed his dreams made him return to his true nature, and the scarlet in his eyes instantly receded.

"It's nothing, you go back and practice with them, I'll go to other tunnels. Saying that, Yuanwei was a little flustered, chose a hole at random, and stepped in.

"Brother, don't go to that tunnel! Oh, it's over...", she exclaimed, as if she was extremely dissatisfied with Motoo's itinerary, she didn't dare to enter the atrium, and after hesitating a few times, she finally had the courage to cling to the edge of the wall, bypassing the atrium to the tunnel where Motoo was.

Motoo had already gone dozens of feet deep into the tunnel, and there, he saw several cute rabbits. Some of the rabbits were white, some were black, and they were all cultivating in the forging vein realm, and seeing the arrival of Yuanwei, the rabbit was very well-behaved.

"Enchanting Demon Rabbit, you get away from me, this is my younger brother, don't try to charm him. The disturbing dream behind him shouted.
