readx;?“ Boom!"

Under Lin Feng's urging, the Yuan Qi Light Ball immediately exploded on the surface of the boulder. Pen & Fun & Pavilion www.biquge.info//, QB5, \\ dazzling light immediately shot out in all directions.

After the lightning, Lin Feng looked towards the boulder again.

"How is this possible?" the boulder had not been damaged in the slightest after such a powerful attack. You must know that Lin Feng is also a powerhouse of the Void Breaking Mirror now, and with his full force, I am afraid that the entire mountain can make a deep hole. But the boulder didn't have the slightest impact.

"What kind of stone is this?" Lin Feng couldn't help muttering to himself, and then looked up and down at the boulder in front of him. After experiments, he knew that he would not be able to pass by hard touch no matter how he did today, so he had to find the mechanism again.

"If I'm not mistaken, this should be the Black Oblivion. At this time, Hou Yi in the Sun Fire Crystal suddenly spoke.

"Black Oblivion Stone?" Lin Feng asked with some confusion.

"Not bad. This black annihilite is an extremely rare material. If you add some when refining defensive magic weapons, the defense effect will be increased several times. There is probably no second place in the world that can have so many black annihilations. Hou Yi kept smacking his lips as he spoke.

"Then this thing should be very expensive, right?" Lin Feng asked curiously.

"Hmm. His price should be comparable to that of Tian Yuan Stone. Hou Yi said indifferently.

"What?" Lin Feng couldn't help but feel his head swell. What is the concept of being comparable to the Tian Yuan Stone, the price of a small piece of Tian Yuan Stone is comparable to a spiritual weapon, and if such a large black oblivion stone in front of you is comparable to the price of the Tian Yuan Stone, wouldn't it be sky-high.

"Don't be surprised. Even if the price of this Black Annihilation Stone is comparable to that of the Tian Yuan Stone, I'm afraid it will be impossible for you to sell this big stone for money. The mining of the Black Oblivion Stone originally required a tool called the Heavenly Xuan Iron Staff, and if you didn't let your Yuan Force be strong, you wouldn't be able to split it. Hou Yi said with a smile.

"I really don't have it. Lin Feng couldn't help but say with some regret.

"So, you'd better find a way to find a mechanism! Hou Yi reminded him and then stopped talking.

Lin Feng had been looking here for a full hour, but he couldn't find out where the mechanism here was, so he couldn't help but be a little discouraged.

"It seems that today can only be in vain. After Lin Feng muttered, he turned around and retreated back the way he had come. But just when Lin Feng had just walked out and looked back at the boulder helplessly, a strange scene appeared, the boulder that was originally blocked there disappeared at some point.

"Hmm, could it be that the boulder will leave on its own?" Lin Feng couldn't help but look at the depths of the cave with some curiosity, a crooked path stretched out into the distance.

"It's weird. Lin Feng felt very puzzled, but at this time, since the boulder took the initiative to give way to the road, there was no reason for him not to continue exploring. So, Lin Feng took a deep breath and walked towards the depths of the cave again.

When passing by the location of the boulder, Lin Feng deliberately paused for a moment and carefully observed the stone wall of the cave, as if there had never been any black oblivion stone here at all.

"It's really amazing here!" Lin Feng couldn't help but admire, and then continued to walk forward.

As he walked, Lin Feng suddenly felt that the front suddenly brightened. A large hall appeared in front of him. There are more than 100 meters high stone walls carved with various patterns. And in the center of this hall, there is a small seven-story tower.

"Heavenly Mother Tower?" Lin Feng couldn't help but show a hint of joy. According to the information he collected, this Heavenly Mother Pagoda is the most mysterious place in this Heavenly Mother Cave, and it is also the last place where the Queen Mother of the West stopped before ascending. And the treasure of the Queen Mother may be in this Heavenly Mother Tower.

However, although this is only a small seven-story tower, and countless people have entered it, no one has obtained the so-called inheritance treasure here.

Lin Feng calmed down his excitement at this moment, and did not rush into the tower, but circled around the Heavenly Mother Tower. However, when he looked around, Lin Feng didn't find anything special about this tower. So, in the end, Lin Feng still stepped in through the main entrance.

As Lin Feng stepped through the tower gate on the first floor, a red-golden halo was about to envelop him. When he entered the tower smoothly, he slowly disappeared.

On the first floor is an empty hall, surrounded by many shelves, where there are probably a lot of books or elixirs, but after tens of thousands of years, those things have long been taken by the predecessors.

Lin Feng looked at the empty shelf, shook his head, and then looked around for a week, then his gaze fell on the ancient wooden staircase.

According to Ming Feng, this staircase is very special, and every time you take a different step, then the floor you go to is also different. It seems that the higher the stride, the higher the floor you reach. There had been a time when someone had only taken two steps, and that person had been teleported directly to the sixth floor.

However, the vast majority of people can only take three or four steps, although everyone who enters is above the Void Breaking Mirror, but all the Yuan Power on this staircase cannot be used, so they rely on the strength of their bodies to step forward.

A strange thought suddenly rose in Lin Feng's heart at this moment, and he reached the sixth layer with two steps, so if he took one step, would he be directly teleported to the seventh layer? Thinking of this, Lin Feng couldn't help but secretly rejoice, after all, he had the Cloud Walking Boots with him at this time, and the Cloud Walking Boots didn't need to consume Yuan Power at all, so he might really have the opportunity to reach the seventh layer in one step.

Thinking of this, Lin Feng smiled slightly, and glanced towards the staircase, a looming wooden door was hidden at the end of the staircase, if he stepped there, it might be the gate of the seventh floor.

"Let me see what's so strange about this seventh layer today!" Lin Feng muttered to himself. Then with a force under his feet, a phantom flashed, and the whole person came to the hidden wooden door. The entire staircase takes only one step.

Lin Feng stretched out his right hand and slowly pushed the door open, suddenly shooting out countless brilliant rays of light from the door. Even Lin Feng had to close his eyes for a while to get used to such a strong light.

When he opened his eyes again, the light had faded a lot. At this time, Lin Feng carefully observed the scene behind the door. A small room, with a lot of furnishings, as if it had not been inhabited for many years, and a thick layer of soil covered the entire house. And that bright light just now emanated from an oil lamp in this room.

"What is that?" Lin Feng couldn't help but mutter.
