"I've been going around in a lot of circles in the middle, why haven't I found out where the machine is yet, could it be that Long Wu has also set up a maze in the last level?"

"It's all the way to the road, how can there be a labyrinth?"

"It seems to be getting closer. "The man of Lin Yi could not describe his feelings, as if in the darkness not far away, some mysterious aura had some connection with him, there was someone waiting for him, he had been waiting for him for many years.

"I don't know what's going on outside. Yan Xu said, and quickened his pace again.

The three of them turned around a stone wall, traveled about forty or fifty meters, and suddenly stopped at the same time.

The cave in front of it seemed to be completely different from all the previous caves under the reflection of the black flame stone, but it was impossible to tell where the strangeness came from for a while.

"Hedrons?!" Shen Yunpeng's voice carried a hint of consternation.

"Put the Black Flame Stone away. Lin Yiren said, blew the fire fold, and walked slowly forward.

The black walls of the cave are covered with raised prismatic crystals, different from the fine fragments of light reflected by the black flame stone, when the Lin Yi people light the fire, the entire cave wall exudes brilliant colorful light, white, purple, blue, gold, red, green, blue, black...... Lin Yiren's starry eyes swept around, but there was no yellow spar.

The three of them continued to walk all the way in the spar cave, but unexpectedly, the cave was going round and round, twisting and turning, as if there was no end.

"The walls of the hedron cave are too hard to be bracketed. There was a hint of worry in Yanxu's voice.

It has been an hour since entering the cave, and even if the people and horses outside have the support of Xiling Palace, they can't last too long.

"Not necessarily. Lin Yiren suddenly stopped and looked at the spar in front of him on the left, "At that level, Yan Gongzi once said that when the imperial grandfather came in, he would hold a slender and sharp object to trigger the bottom of the cave?"

Yanxu heard the meaning of Lin Yiren's words, and immediately followed Lin Yiren's line of sight, a thin sword hilt was inserted in a cluster of purple crystals, if you don't look closely, it is easy to be ignored.

"The sword has pierced into the ......," Yan Xu frowned and looked around, "So, the mechanism for placing the five tokens has also been opened?"

"Since all the brackets are in place when entering the cave, it means that the brackets in the cave can be opened or closed, and it is better to let it show its true face again than to find it hard. Lin Yiren said, stepping forward and drawing his sword.

This is a sword that has not yet been opened, slightly shorter than the ordinary sword, the color is simple, there is no sharp air, in the hilt and the sword body are connected, carved a small "Huan" character.

Lin Yiren's hand shook, this is the emperor's sword, the hilt of the sword he holds, also held in the emperor's hand, this sword has been inserted in the stone crack for thirteen years, thirteen years ago, when the emperor's grandfather resolutely walked into the Nine Xuandong, did he expect that there would be so much turmoil in the country after that?

Click...... A soft sound came from all directions.

"Bring the token. Shen Yunpeng said suddenly.

Lin Yiren glanced at each other and walked to Shen Yunpeng's side.

In the shadow above a cluster of red hedrons, there is a groove that closely matches the outline of the token, but the bottom of the groove is a flat mountain rock, without the clear convex and concave lines of the keyhole before, because it is stained with red light, it looks extremely strange.

"The five tokens must be placed on the keyhole at the same time, and if the difference is a fraction of a second, the Nine Xuan Caves will collapse, and the Bone Immortal Grass will destroy ......," Lin Yiren muttered.

"That's right. Yan Xu said and put the Gang Order into the groove, "As expected, in order to allow Emperor Huan to embed five tokens into the keyhole at the same time, Long Wu must also have set up a mechanism to control the mountain rock below the five tokens, and the sword that was closed just now must be this mechanism." ”

Since the direction is clear, the three of them immediately began to act, and the target directly locked on the cyan, white, and black spars, and after a while, the slots of the three tokens of the Alfalfa Ruler Order, Chen Yan Order, and Wuyu Order have all been found, but the yellow spar, Lin Yiren didn't know what to do with Yan Xu.

"The central positioning, the difficulty lies in the spatial layout. Yan Xu seemed to know Lin Yiren's thoughts, "If the prince is on the outside, overlooking Jiuxuan Peak, the earth line among the five elements of metal, wood, water, fire, and earth before is just a place where the east, west, north, and south diagonally intersect. ”

When Lin Yiren heard this, his heart moved...... Now that the four corners of the spar cave have been determined, isn't the location of the begging order about to come out? The Lin Yi people immediately walked to the general direction of the visual inspection, and sure enough, next to the golden spar, they found a groove that was consistent with the outline of the begging yuanling.

"With gold to imply the dignity of the emperor's grandfather, with the royal and the five elements of the yellow matching, the dragon five is really unique. Lin Yiren sighed.

"Please put the sword back in its place. Yan Xu said.

The Lin Yi people did as they were told, clicking...... There was a soft sound in the east, south, west, north, and middle directions at the same time, and it was obvious that the Chenyan Order, the Wuyu Order, the Qiyuan Order, the Gang Order, and the Alfalfa Ruler Order had been embedded in the keyhole.

However, the expected roaring sound of the opening of the machine did not come, and after a few breaths of suffocating silence, a sound of running water came into my ears, and the sound was clear and pleasant, like a ring striking each other, as if it were close at hand, and as if it were far above the sky.

Immediately afterwards, there was a faint refreshing fragrance in the air, because of the poison of the phantom incense, Lin Yiren, Yan Xu, and Shen Yunpeng immediately held their breath.

Poof--The strong wind that came from nowhere blew out the fire in the hands of the Lin Yiren.

Darkness, utter darkness...... Shen Yunpeng was about to take out the Black Flame Stone again to illuminate the cave, but was stopped by Lin Yiren's outstretched hand.

"Look at the roof of the cave. "Lin Yi is humane.

Yan Xu and Shen Yunpeng looked up, and at some point, there seemed to be a dense light flowing on the top of the cave, and the words "Nine Xuan Cave" gradually became clearer and clearer in the dark.

"The third word ......" the words groaned slightly.

Lin Yiren looked at the word "hole" in the "Nine Holes", and in the "mouth" of the word "hole", a dark beam of light shone on the blue spar below, and then reflected to the green spar a few steps away, and then to the cyan spar on the opposite side, and after three turns, the beam was so faint that it was almost impossible to distinguish.

The Lin Yi walked up to the prismatic cyan spars, carefully touched them one by one, and finally found something strange on the low spar in the lower right corner.

"The hedron is a little loose. ”

"Press it. Yan Xu said.

Click-la-la-...... This time, the trio finally got their wish and heard the deafening sound of rolling stones. Five zhang away, the rock wall that was originally covered with spars retreated backwards, and the looming light source finally slowly revealed its true face.

Whoosh - a crimson figure quickly swept past the Lin Yi people, rushing towards the rock wall, at this moment, anyone knows that the front is the place where the bone fairy grass is located, and whoever can seize the opportunity is to grasp the initiative.

Yan Xu's expression changed suddenly, and Ling Yun stabbed out in an uproar, rushing straight to Shen Yunpeng's heart. At the same time, Lin Yiren held the wind like a blade and slashed diagonally towards Shen Yunpeng.

Dang! Lingyun Thorn was struck away by Shen Yunpeng's sword, and hit the mountain rock, splashing a spark. Lin Yiren's killing palm was unpredictable and stopped in front of Shen Yunpeng.

One person's offensive is unmatched, and the other person's defensive position is impermeable, but this dizzying effort, the words have been like meteors catching the moon, and they rushed into the rock wall first.

The sword is like a swimming dragon, stabbing and slashing, the palm is unstoppable, Shen Yunpeng is impetuous, and he does not have the upper hand, and Lin Yiren is calm, but he also fails to gain the upper hand.

"Stop fighting......" Yanxu's voice came from behind the rock wall, as if with an indescribable amazement.

Lin Yiren and Shen Yunpeng's bodies were staggered, both of them were wary in their eyes, and they stopped their moves.

After entering the rock wall, the people of Lin Yi finally understood where Yanxu's astonishment came from...... More than ten zhang away, a huge ball of light was suspended in mid-air, like a mist like a cloud, and golden light flowed.
