In the dark cave, a few frightened bats flew overhead from time to time. Here, the only means of lighting for Li Jinyi and his party is the "flashlight" function of the mobile phone.

The surface of the cave is covered with a layer of fine sand, which has a slightly damp smell. The predecessor of Cloud Peak Star Island was a huge bedrock at the bottom of the sea that carried the engine of creation, and this cave was probably caused by the erosion of undercurrents in the sea hundreds of millions of years ago.

Many branches appeared in the cave, and Lu Xin led the way in front according to the marks he had made before.

"Why haven't you arrived yet?" Lena was impatient.

"It's still early, if you can't hold on, you can retire first. Lu Xin walked in front and said without looking back.

"Who can't hold on! I'm thinking for a moment that if the phone runs out of battery, and the three of us can't just do magic, we won't be able to see anything at that time, so we won't be trapped in here? Really, I didn't even bring a lighting tool in advance to a place like this. The two big men didn't know how to prepare well in advance when they did a bad thing, and they laughed to death!" Lena gave full play to her expertise as the head of the Discipline Inspection Committee and lashed out at the two of them.

"It's noisy! Who said I didn't bring lighting tools?" Lu Xin glanced back at Lena with disdain, put the phone back in his pocket, stretched out his right hand, and spread his five fingers.

In an instant, countless pure white dazzling lights began to converge in his hands, and layers of light bloomed, illuminating the area within dozens of meters before and after the cave. The light faded, the silver glow dissipated, and a straight knife flowing with white brilliance appeared in the palm of his hand, and a little silver halo spread across the blade, like stars dotting the night sky. This star soul weapon, which is not recorded in the information, is called Yun Yesheng, and it was obtained by Lu Xin from nowhere when he was a child.

As the blade was summoned, the surroundings suddenly lit up.

"Look, isn't this a lighting tool? It doesn't waste electricity. Lu Xin licked Yun Yesheng's blade in front of Lena.

"No matter how you look at this weapon, it looks exactly the same!Lu Xin! Honestly, did you go there in the autumn of 8 years ago......" Lena reached out to grab the weapon, but was dodged by Lu Xin.

"How many times have I quibbled with you—no, how many times have I explained! The person you are talking about is not me!" Lu Xin said and ran towards the depths of the cave without looking back, looking a little flustered.

Lena froze in place, and immediately gritted her teeth and chased after her, shouting, "What are you lacking in heart! Don't run! Stop! Give me back your things!"

What is going on? Li Jinyi, who was walking at the back of the line, saw this scene and muttered in his heart, 8 years ago, wasn't that when Lena just transferred to the Star Royal Academy, it was earlier than I met Yin Yuyao. That's right! When she was on the helicopter before, Yin Yuyao seemed to have said that Lena came to the Star Royal Academy because something happened to her family, could it be related to Lu Xin?

Li Jinyi made up the following scenes:

It was a dark and windy night eight years ago, and Lu Xin, a ten-year-old flower thief, stumbled into the room of Miss Lena Fields, the highest point of Nightingale Fortress in Northern Europe. Lu Xin saw that she was beautiful and cute, and her heart suddenly rose, and in a blink of an eye, she harmed the daughter of the head of the star's family. Afterwards, afraid that the reputation of the Fields family would be damaged, Lena didn't dare to let others know about it, she learned from the mouth of the flower thief that he was from the Star Alliance, so she went here alone to ask for an explanation, but Lu Xin has never admitted it until now.

It's inappropriate, Li Jinyi shook his head, it seems reasonable, but it is actually full of loopholes. According to Lena's character and strength, if Lu Xin really did this before, she would definitely be torn to pieces by her at the first time. Besides, Lu Xin doesn't look like a person who would do such a thing, he is a dead sister who only has his sister in his eyes. Hiss~ Why is that?, it's useless to think about it here, I have time to ask Yin Yuyao in detail, she should know something. Thinking of this, Li Jinyi quickened his pace and kept up with the two in front.

Since the ground inside the cave was much flatter than the forest, they walked as if they were walking on the ground, and after an hour, they had already walked out of the forest underground area and entered the underground of the northern holy mountain area.

The cave wall in the corner ahead reflected a pale blue glow, and the light source seemed to come from the other end of the corner.

"Arrived, turn left ahead. Lu Xin pointed to that place.

"Hey, it's finally here, I thought you were lost and taking us around. Lena took Yun Yesheng and pointed in front of Lu Xin, dangling around.

"Okay, okay, have you had enough? There's the light from the Star Soul Crystal here, and I don't need the lighting of Yun Yesheng, I'll release the summon." Lu Xin moved his fingers as he spoke, and the pure white blade in Lena's hand immediately turned into smoke and disappeared without a trace.

"What are you doing! That's my thing, why do you say disband, disband!" Lena pouted, her eyes full of unwillingness.

"Your thing, please summon it. Lu Xin looked at Lena, spread her hands, and twisted her shoulders proudly.

“......”

Li Jinyi just wanted to see the appearance of the ore vein, and he didn't bother to pay attention to the two people who quarreled every day.

I couldn't wait to pass between the two in front of me, and when I turned around the corner, he ushered in the Nth shock of the day.

This is a naturally formed huge underground cavity, hundreds of meters in diameter. Countless light blue star soul crystals of different sizes were embedded in the four walls and dome of the cave, lighting up the entire space. There are also many large fissures in the walls of the cave in the distance, through which people can pass freely, and from time to time a few small animals resembling rabbits or lizards will run in and out of them.

"Oh my God! That's too much. Lena, who came later, couldn't help but marvel at the whole view of this place.

"I didn't lie to you!" Lu Xin said proudly, "Look at those cracks in the cave wall, there are also caves in them, and there are still a few of them that have not been explored, Jin Yi will go with me later, Lena is waiting here." ”

After Lu Xin finished speaking, he glanced at Lena to see her reaction. Lena didn't speak, she looked at him coldly, her fists clenched and relaxed. Lu Xin's heart tightened, it's not good! It's a sign when this girl is about to beat someone!

"The terrain in the crack is complicated, what if you slip under your feet and fall into a deep hole? Lu Xin hurriedly explained.

Lena remained silent, her crimson pupils revealing a murderous aura.

"It's all here, let her go with her. Li Jinyi, who was on the side, saw that this momentum was not right, and hurriedly suggested.

"Are you fully responsible for what happened?" Lu Xin glared at Li Jinyi.

"Ouch, the weather in this cave is pretty good. Li Jinyi whistled and looked around, pretending not to hear, he didn't dare to take this responsibility.

"Pretending to be crazy and stupid, alas. Lu Xin sighed and looked at Lena: "You better go with you, you will run around if you stay here anyway, and it will be even more troublesome if you get lost." ”

"Hehe, Crack Exploration Team, dispatch!" Lena suddenly stopped with murderous aura around her, and instantly burst into a smile.

Several people passed through the Star Soul Crystal Cluster and burrowed into a relatively narrow crack. There are also many star soul crystals "growing" in this crack, and the vast number of crystals are like a mirror array, reflecting the appearance of the three people from various positions, and stepping into it is like being in a kaleidoscope.

Li Jinyi suddenly seemed to remember something, leaned down, and broke a small piece of star soul crystal from the ground and put it in his pocket.

"Hey, why do I have so many leaves on my head!" Lena looked at her reflection in the crystals beside her, and quickly brushed her hair.

"You just found out, it must have been made in the forest, but this is more in line with your temperament. Lu Xin pouted and said.

"you!" Lena crumpled the dead leaves mixed in her hair and smashed them at Lu Xin.

The further you go in, the narrower the crack becomes, and in the end, only Li Jinyi and Lu Xin can barely pass sideways, and because Lena is a girl, even if she collides sideways, she has a large volume, so she has to stop and wait.

But it's also a girl, if it is replaced by Lu Yixuan, she should be able to easily pass through there sideways.

Li Jinyi was the first to squeeze in, moving deeper inch by inch.

"I'll go in and investigate, and you'll stand here and don't move. Lu Xin said to Lena with an eyebrow, and then twisted his ass and moved towards the depths of the crack.

This blatant provocation made Lena angry.

"F**K!" she kicked at the narrow cave wall in order to vent her anger.

"Click!"

A noticeable crack appeared in the cave wall.

The cracks gradually spread, and the cave walls began to crumble.

The eldest lady of the Fields family was so frightened that she lost her face, she didn't expect this cave wall to be so fragile, looking at this posture, should there be a big collapse and bury a few people here forever?

"Come out of here, the cave is going to collapse!" she shouted into the cave, unfurling a magical shield in her hand.

"Something happened?" Li Jinyi, who was in the innermost, heard the voice and turned his head to look at Lu Xin.

"It sounds like yes. Lu Xin nodded, and the two hurriedly moved outside again.

Lena poured more energy into the magic shield to enlarge it, and she wanted to cover the crack with the entire enlarged shield to prevent it from collapsing.

But she didn't expect that the moment the shield touched the crack, the cave wall would collapse outward.

Is there still a hidden space in the walls of this cave?

The smoke and dust from the collapse blurred the vision, and it was not clear what was going on that side for a while.

Lu Xin and Li Jinyi crawled out of the narrow crack on the side and watched this scene with trepidation.

"You, what have you done?" Lu Xin's head was full of question marks.

"Uh...... Hey. Lena smiled awkwardly and turned her head away in embarrassment.

The smoke and dust gradually cleared, and behind the collapsed cave wall, a dim space appeared in front of the three of them.

When the dust settled, several people walked into it one after another, and Lu Xin summoned Yun Yesheng to illuminate the entire space.

I heard a trickle in my ears, and when I looked up, the roof of the cave kept seeping out, eroding the four walls. Lai Jinyi walked behind a protruding rock and was surprised to find that the water had eroded a passage that could be entered, and the passage was not long, and there seemed to be a bright light coming from the other end.

"Come and see. Li Jinyi whispered to the other two.

Lena ran to Lai's side and looked down.

"That's the color of the lights! Someone lives in it?" she exclaimed.

Lu Xin hurriedly covered her mouth and scolded: "Don't yell so loudly, I don't know who is over there." If it's a weirdo who does human experiments, you're going to be arrested and used as a container!"

"Hmm...... Not. Lena struggled to get rid of Lu Xin's control, and judging from this picture, it seemed that Lu Xin himself was more like the weirdo he described.

"I'll go down and have a look. Li Jinyi looked up and said to the two.

"Be careful. Lu Xin nodded.

Lai Jinyi performed a slow fall technique, passed through the pipe, and landed on a convex rock. He looked around and found himself in the middle of a large vertical cavern, where the rock was sticking across the walls of the cave, and several searchlights were converging somewhere below a short distance overhead.

Lu Xin and Lena also descended here from the passage, and the three of them cautiously walked to the edge of the rock and looked down.

Where the spotlights converged, a burly, long-haired, hunchbacked old man was kneeling at the bottom of the cave, surrounded by rocks, his hands firmly held in place by two thick star soul crystal chains.

Lai recognized the prisoner at a glance.

"We're breaking into the dungeon where Saquig is being held?!" Li Jinyi tried to keep his voice low, but he couldn't hide his surprise.

"It's over, if we are found by the prison guards, it won't be as simple as school punishment!" Lu Xin looked panicked, and he had the intention of going home immediately.
