Lu Mingfei saw such an iron box for the first time, where did he know Ke Lina's method of opening the box, and after trying many methods, he was always at a loss.

The iron box is like growing on the stone platform, no matter how it can't be moved, these can't help Lu Mingfei, after hesitating for a while, Lu Mingfei simply pulled out the chopping and tried to cut it towards the stone platform.

Although he couldn't shake the iron box, he could cut the stone platform, and after tossing for a while, Lu Mingfei actually cut the entire iron box from the stone platform with a stone slab.

Yin Zhelu looked at this side intently, until Lu Mingfei took off his robe and wrapped the iron box into a robe and tied it into a package, then he discovered the existence of Yin Zhelu on the other side.

Walking quickly to the side of the ice wall, the two of them each said a few words, but they couldn't hear each other's voices, Lu Mingfei compared the iron box that he had just won, and the excitement on his face had not faded, and then he noticed the iron box that had been opened on Yin Zhelu's side.

Lu Mingfei stretched out his finger and pointed, revealing an inquiring look, with a slight surprise on his face, while Yin Zhelu spread his hands helplessly and shook his head again.

I thought that Yin Zhelu had also gained something, but after seeing his expression, Lu Mingfei immediately realized that Yin Zhelu's side had failed, and the previous joy was gone, after all, it was at his suggestion that the chosen hole was exchanged, which would only make him feel guilty.

Yin Zhelu saw that Lu Mingfei stretched out his hand and pointed at the iron box in the package again, and he didn't know what Lu Mingfei said, and was thinking about trying to communicate, when suddenly Lu Mingfei's back lit up, and the stone wall opposite became transparent.

Lu Mingfei looked back and saw Yu Yingxue standing in the stone room, holding half a "chopstick" in her hand and constantly looking up and down.

Almost the same stone room, the same experience, after Yu Yingxue entered the stone room, she saw the iron box placed on the stone platform, and the lid of the box opened by itself, but it was slightly different from the situation encountered by Yin Zhelu Liqing, in the iron box, there was such a slender thing, a palm long.

Yu Yingxue quickly noticed Lu Mingfei's gaze, and immediately came to the ice wall and pasted the small stick on the ice wall.

Looking at it closely, it is clear that the surface of the small stick has extremely fine lines, if it is chopsticks, it is slightly flattened, if it is said that it is an awl and it is not thin enough, it looks like jade and not jade, and it looks like iron and non-iron and cannot see what material it is.

Yu Yingxue looked at Lu Mingfei, it seemed that she didn't know what the origin of this thing was, after a few checks, the little stick really didn't have much special, it was not like the short knife that Ke Lina obtained, the aura contained in it was obvious, and it could be seen that it was extraordinary in a word.

But if it is an ordinary thing, how can it appear in that iron box?

Lu Mingfei was also a little confused, Xiao Bang was naturally the first time he had seen it, but he faintly felt a little familiar.

Suddenly remembered that before entering the ruins, Nan Yimeng had taken out a similar short stick when he opened the third door, although he hadn't looked at it carefully, but Lu Mingfei still had a deep impression, no matter in terms of color and texture, it was very similar to the thing Yu Yingxue was holding in his hand.

"The key? This is the key. ”

Thinking of this, Lu Mingfei blurted out a sentence, but across the ice wall, Yu Yingxue naturally couldn't hear any sound.

At the same time, Yu Yingxue seemed to remember something, stretched out her hand and pointed at her head, and then used her two fingers to draw a length.

"Hairpin?!"

Lu Mingfei will immediately

At the same time, I remembered the "chopsticks" I dug out in the big pit of the old house outside Nanfeng City, and was later used as a hairpin by Yu Yingxue.

Looking at the short rod in front of you, the color and material are indeed very similar to the hairpin, the difference is only the length, compared to the one in front of you is obviously much shorter.

Both of them were at a loss, knowing that this thing might have any origin, but there was no basis at all, just when the two of them were pondering for this, Qi Xiaobai in the stone room on the far left finally completed the tempering.

The original hammer had been damaged in the process of building, leaving a pile of large pieces of iron, and the newly created hammer was black, extremely ordinary in appearance, the hammer was not round and irregular, and it looked more like an ordinary farm tool.

It seems ordinary, but the power in it is probably only known to Qi Xiaobai, he raised the hammer and looked it up and down carefully, Qi Xiaobai nodded with great satisfaction, and the corners of his mouth bloomed.

He weighed the weight of the hammer again, and couldn't wait to try it, so he simply picked up the hammer and slammed it towards the ice wall on one side.

A dull loud noise clearly reached the ears of Lu Mingfei and the others, and several people were stunned at first, and then turned around to look to the left in unison.

After a while, I saw that the ice walls in the various stone caves suddenly shattered inch by inch and scattered all over the ground, and the whole earth continued to tremble, no one thought that Qi Xiaobai would open the passages in all the stone chambers with such a hammer.

Such a great power was also beyond Qi Xiaobai's expectations, and she didn't know whether she had done a good deed or caused a big disaster, the ice wall had been shattered, and she hurriedly carried the hammer towards Lu Mingfei's side.

The tremor of the earth did not stop, but became more and more violent, and several stone platforms shattered at the same time, and the iron box on the platform sank and was buried in the ruins.

The stone chamber was about to collapse, and several people immediately rushed to the stone chamber on Yu Yingxue's side, the same shaking did not stop, but for some reason, the stone chamber in the middle was always intact, not quite the same as the two sides.

Before they could react to what was going on, on the other side, Kelina and the Three Flame Boys also ran towards this side, their faces a little frightened.

When I walked to the fifth stone room, I happened to see Li Qing who was unconscious, but fortunately, Kelina came in time and rescued him.

Lu Mingfei immediately stepped forward to investigate, and saw that Li Qing's body was still glowing with a faint golden light, his body was full of Xuan Qi, and his breath was stable, not only did he show no signs of injury, but he was much better than usual, but for some reason he was unconscious.

Seven people gathered together, glanced at each other, the most proud and excited was Qi Xiaobai, seeing that the hammer in her hand seemed to have changed, and there was nothing else to gain, several people were a little puzzled, and they didn't know where Qi Xiaobaixi came from.

And the package that Lu Mingfei was carrying behind and the short knife in Ke Lina's hand quickly attracted the attention of the others.

"What are you, what's the big bag?"

Ke Lina pointed behind Lu Mingfei and asked curiously.

Lu Mingfei didn't have time to explain in detail, and then said: "I don't know what the specifics are, I'll talk about it when I get out, your knife?"

As she spoke, she looked at Corina's hand.

Ke Lina immediately brought the short knife to Lu Mingfei and Yu Yingxue and said, "Finding this knife in the stone chamber looks unusual, do you need it?"

It is not clear what the dagger has

The special features of the body, but Kelina doesn't seem to pay too much attention to it, listening to her meaning, it is who uses who takes it.

As the ice wall continued to shatter, the stone chamber that was originally shining with pale green light gradually became much darker, and several people realized that the original light in the stone cave was actually from the ice wall.

Ke Lina looked at the dim surroundings and said to Lu Mingfei: "I don't know how long this stone room can last, maybe the whole mountain will collapse, let's go out quickly." ”

"Wait a minute!"

Before she finished speaking, Yu Yingxue suddenly stopped, looked at a few more people and asked, "Which of you has found the phoenix marrow?"

Only then did she remember that Yu Yingxue's purpose for coming here was to find the phoenix marrow, and Ke Lina glanced at each other and shook their heads helplessly.

Yu Yingxue's face sank, looking a little disappointed and hesitant, Lu Mingfei hurriedly comforted: "When you come here, everything is about a chance, and you can't force it, so let's go out first." ”

Yu Yingxue didn't answer, still a little unwilling, Lu Mingfei looked around and asked, "When you came over, did you see that there was a way out?"

"It's easy to do. ”

Without waiting for a reply, Qi Xiaobai suddenly stood up, smiled at Lu Mingfei and said, "I'll get you a way out." ”

I saw that the black sledgehammer was accompanied by a black whirlwind visible to the naked eye, slamming forward, and the last ice wall in the stone chamber was knocked down by Qi Xiaobai with a hammer, making a big hole, and at the same time, the entire stone chamber also fell into complete darkness.

"Alright, let's go. ”

Qi Xiaobai withdrew the hammer, nodded with satisfaction, and was about to walk forward, when a subtle beam of light suddenly shot out behind him.

Looking back, I saw that there was a small hole the thickness of a small finger on the farthest stone wall behind him, which transmitted a pale yellow light, the small hole was not large, and the light was not bright, it was indeed difficult to detect if it was not completely plunged into darkness.

Lu Mingfei and Yu Yingxue understood something at the same time, and they all ran quickly towards the small hole where the light was transmitted.

Yu Yingxue inserted the short stick in her hand into the small hole, trying to turn it left and right, and heard a "click", and the stone wall suddenly parted on both sides, revealing a large hole that extended downward.

"Sure enough, it's a key. ”

Lu Mingfei whispered, and at the same time confirmed his previous judgment, looking down, there was a dim light in the big hole, which was very deep, and he couldn't see the bottom at all.

"What is this place?"

Several people immediately surrounded them, but their faces were a little dazed, and no one knew where the suddenly opened hole would lead.

"I'll go down and take a look, the phoenix marrow may be hidden here. ”

Yu Yingxue almost didn't hesitate, she was going to walk towards the cave, but Lu Mingfei pulled her back, maybe because the previous experience was too smooth, Lu Mingfei inexplicably felt that there seemed to be some kind of danger in this stone cave, where to rest assured that Yu Yingxue would enter so casually.

The two glanced at each other, there were some things between the two of them that did not need words, Yu Yingxue saw the concern and worry in Lu Mingfei's eyes, and Lu Mingfei also saw the resoluteness in Yu Yingxue's eyes.

"Since you're going, I'll go with you. ”

Lu Mingfei knew that Yu Yingxue would not change his mind once he made a decision, so he walked towards the cave before Yu Yingxue.
