The first rays of sunlight in the morning fell on the entrance of the cave, Ai Li woke up Wulian, and the two of them ate some dry food and went into the cave to explore.

The sun was rising outside the cave, but it was getting darker and darker inside. When it was so dark that he could barely see the way, Ai Li lit a fire fold. The light of the fire fold shone on the cave wall, faintly condensing into a ball of light.

Wu Lian had already experienced a cave exploration, so she was not as scared as she was last time. He took Ai Li's hand and followed behind her, his heart calm.

After some time, we came to a fork in the road. Ai Li stopped to check, hesitating to go that way.

Wu Lian suddenly happily pointed to a mark and said, "Sister Ai, look, this is the mark left by my master, let's follow this mark, and we can find the dragon's back." ”

Ai Li took a closer look, and the mark of the stone was carved on the rock with a sharp weapon. The top is a semicircle, and there are several flame-like lines below, and the whole looks like a half moon rising from the fire.

Ai Li touched the mark on the stone and said, "Your master should also know martial arts, his internal strength is not weak." ”

Wu Lian said gloomily: "The master is very powerful, I was rescued by the master from the bad guys." It's a pity that he always has something to do, and the time he spends with me is short. ”

Ai Li saw that Wulian's eyes were wet again, and hurriedly said, "Let's go." ”

The two of them walked along the markers of the stones, and the path went up and down, and at other times they had to crawl on all fours.

I don't know how long I walked, Ai Li suddenly stopped, and there was an extremely steep slope in front of him, and the black hole below looked extremely deep.

Ai Li said to Wulian: "You wait here, I'll go down first, if it's okay, I'll call you again." ”

As she spoke, she took the fire fold in her mouth and slid it down.

In the dark, time seemed to stand still, Wu Lian only felt that his heart was pounding, and without Ai Li, his fear rose again, and his body trembled involuntarily. He hugged his shoulders tightly with his arms and waited in silence.

After about a cup of tea, Ai Li's cry was faintly heard at the bottom of the cave, and he breathed a sigh of relief, closed his eyes, and slid down the steep slope.

The steep slope is extremely long, and from time to time there are rocks that bulge abruptly, which makes Wulian's whole body ache. He closed his eyes tightly and didn't dare to open them, only to feel the wind whistling in his ears, and his heart hung up, almost jumping out of his mouth.

Suddenly, there was a violent shock to the body, and there was a sudden pain in the back of the buttocks, as if it had touched a hard place. Wu Lian carefully opened her eyes, reached out and touched it, and there was land all around, and it turned out to be the end.

Wulian stood up and softly called "Sister Ai" a few times, but Ai Li did not respond. There was a flickering fire in the distance ahead, and he gritted his teeth and ran towards the fire as fast as he could.

Under the firelight, Ai Li was holding the fire fold and watching something carefully.

Wulian rubbed her eyes and looked over as well.

A tall stone gate stood in front of him. The stone gate is five or six zhang high, and in front of the door stands a huge stone figure more than two people high. The stone man looks like a human being, there is a strange single horn on his head, he has a hideous face and holds a big knife in his hand, he has a big mouth and grinning, his eyes protrude and look down, in the firelight, the shadow on the stone man's face is constantly changing, as if he is about to raise a knife to kill, Wulian only glanced at it and did not dare to look at his face again.

Ai Li held up the fire fold and looked for something around the stone gate.

Wulian asked her, "Sister Ai, what are you doing here?" ”

Ai Li said: "You see that since there is a stone gate here, it must be for people to enter, I have tried it just now, this stone gate cannot be opened by manpower, so it should be controlled by another organ." ”

Wu Lian asked, "What will be the control of the organs?" ”

Ai Li said: "I don't know. ”

Wulian was silent for a moment, and also helped her find it.

But after searching for it, they still couldn't find anything that looked like a mechanism.

Could it be in the distance? Ai Li said to Wulian: "You wait here, I'll look elsewhere." ”

"Wait for Sister Ai!" Wu Lian pointed to the big knife in the stone man's hand and said, "You see that this stone man's knife is very similar to your Golden Flame Divine Soldier!" ”

Ai Li looked up and saw that it was indeed the case! The Golden Flame Divine Soldier was a super long knife in the eyes of ordinary people, but in the hands of tall stone people, it was only the length of an ordinary large sword. The stone man holding the broadsword in his hand is exactly the appearance of the Golden Flame Divine Soldier.

Ai Li thought about it, took out the Golden Flame Divine Soldier, jumped up, climbed up to the stone man's arm, and combined the Golden Flame Divine Soldier with the big sword in the stone man's hand. The two knives fit together perfectly!

Ai Li carefully pushed the Golden Flame Divine Soldier, and the soft sound of the "horn" seemed to touch something. The Golden Flame Divine Soldier suddenly shone brightly, and then there was a sound of "squeaking" the shaft wheel turning, and the stone door actually opened inward!

As soon as the stone door opened, a strong wind blew from inside the door, and the fire in Ai Li's hand was extinguished at once.

Before he could think about it, Ai Li took down the Golden Flame Divine Weapon, jumped off the stone man, and pulled Wu Lian through the open stone door to enter.

When they entered the door, their eyes suddenly lit up, and both of them were shocked by the scenery in front of them!

This is a huge natural cave with the walls of the cave slanted upwards and the roof of the cave in an irregular circle. There are countless small holes on the roof of the cave, and the sunlight shines down from the small holes, gathering into countless golden pillars of light of different thicknesses, like a dream.

"It's beautiful!" Wu Lian sighed in confusion in her eyes.

A fresh wind blew through Ai Li's hair, blowing her hair up, although she was silent, there was a flash of intoxication in her eyes, there was a beautiful place like a fairyland.

After standing silent for a while, she said, "Let's go." ”

The two of them walked towards the cave, and along the way they were full of all kinds of strange flowers and plants that they had never seen before. These flowers and plants grow extremely vigorously, and they are more than several meters high, and the two of them walk under the branches of the flowers and plants as if they were walking under a tree. Huge dragonflies like eaglets flew past them, unaware of them. Several huge green long-necked animals were slowly chewing on the leaves, and when they saw them, they only glanced at them, and continued to graze with their heads down, the animals here were surprisingly docile. Ai Li couldn't help but think that if Mo Xiaoyu, the little junior sister who studied medicine, came here, she would be ecstatic.

As we went, countless tiny springs gushed out of the ground, gradually converging into a small silver river that meandered and flowed.

As they walked along the river, they heard the sound of rumbling water in front of them, and as they searched for the sound, a waterfall rushed down a mountainside.

This mountain is very strange, halfway up the mountainside, it is just an ordinary mountain, but above the mountainside is a platform, a thick icicle as a mountainside to the top of the cave. From a distance, the mountain seemed to be cut off by someone and replaced it with an icicle.

Wu Lian excitedly pointed to the icicle and said to Ai Li: "The dragon's spine that the master said should be that icicle!" ”

Ai Liwei nodded and climbed the mountain with Wulian.

Walking to the pillar, Ai Li stopped to watch. The width of this icicle needs to be hugged by ten people, and if you look closely, there are other things inside the icicle, which is actually a stone pillar wrapped in a thick layer of ice outside, but this ice is very thick, more than a meter deep. So from a distance, it looks like an icicle.

Ai Liyun leaned into the icicle with his internal force, and faintly felt that the stone pillar inside the icicle seemed to be colder than ice. She thought to herself and figured out the cause of this icicle: the stone pillar inside should be a huge cold stone. The water vapor in the cave rises, and the cold stone condenses into water on the top of the cave, and the water flows down the pillars and becomes ice again. This icicle is formed over time.

Ai Li sighed: Natural creation, ghostly workmanship, to see such a wonderful scene, it is not worth the trip.

She asked Wulian, "Are you sure this icicle is the dragon's spine that your master asked me to cut?" ”

Wu Lian nodded affirmatively: "My master told me that the dragon's spine of the mountain should be a strange pillar, this pillar is so magical, it must be the dragon's spine!" ”

Ai Li took out the Golden Flame Divine Soldier and gestured at the icicle, and said to Wu Lian, "You go farther away, be careful of hurting you." ”

Hearing this, Wu Lian walked far away to the other side of the mountainside.

Ai Li tried to slash it with the Golden Flame Divine Weapon, and the sound of swords and icicles came from afar, echoing endlessly in the cave. The icicles didn't move.

What a hard icicle! Ai centrifuges the dark passage. She was able to use the Golden Flame Divine Soldier, and the Golden Flame Divine Soldier's golden light skyrocketed. After another loud bang, the icicle produced a crack more than an inch deep.

A light flashed in Ai's eyes, and this icicle was not indestructible.

After a pause, she used all her strength again, and was about to slash at the icicle again, when suddenly, a person ran up from the bottom of the mountain and shouted, "Demon girl, you are really here!" As he spoke, the man grabbed Wulian, who was stunned on the side. The person who came was Zhan Feipeng!

"Let go of Wulian!" Ai Li said angrily and slashed at him with a knife. The Golden Flame Divine Soldier struck at Zhan Feipeng with the huge internal force that he wanted to cut off the pillar.

Ai Li's offensive was extremely fierce, Zhan Feipeng was startled, and hurriedly threw Wu Lian away, drew his knife in his hand, and fought with all his might.

Ai Li pursued Zhan Feipeng all the way, and he was already holding back a breath of anger, but Zhan Feipeng had lost for a while, and he had a competitive heart, and the two knives collided, and the two of them didn't stop, and they each cheered up each other.

Zhan Feipeng's black energy and Ai Li's flame qi spelled together, bursting out with dazzling light.

At the same time, the two found that the internal forces of the two sides were similar. At this moment, they can't stop, as long as one party's internal force is slightly weaker, the opponent's strong internal force will crush them mercilessly. Both of them are people who refuse to admit defeat, each gritting his teeth and constantly increasing his internal force, Zhan Feipeng's head is full of green tendons, and a layer of fine beads of sweat appear on the bridge of Ai Li's nose.

"You crazy woman!" Zhan Feipeng shouted angrily, and suddenly exerted his strength, "The python travels thousands of miles!" "The black energy skyrocketed several times, like a giant python in the rolling dark clouds, striking out in a straight line.

Seeing this, Ai Li was not to be outdone, and also made a trick, "The phoenix spreads its wings!" "The bright red flame rose into the air, like a phoenix reborn from the flames, flying out.

The two of them launched their tricks at the same time, and the brilliance was so dazzling that it was impossible to face it, and there was only one consequence of this blow, that is: never die!
