After a night, in the early morning of the next day, the slimes in the village crawled out one by one, after all, the slimes also had to absorb some light, and for a while the trail was full of colorful jelly, which looked interesting, but at the back of the village, three figures sneakily hid in the grass and stared at the canyon in the distance.

"I said, no matter how you think about it, it's impossible to sneak into the prison and rescue Qiulu when Engel didn't find out, right? What's more, we don't know where Qiulu's prison is. Yang Yi looked at the group of slimes at the entrance of the canyon and said in a low voice.

"There's a way, but we have to work harder. Qing Binghe said helplessly.

"What's the solution, don't you see that the canyon is tightly blocked? Is there a road somewhere else?" Cui He looked around, as if looking for another entrance.

"You guys, don't think of this as a game, this is reality, if it's in the game, it's estimated that you can only kill from this valley mouth, because other places are blocked, but the reality is that as long as you have the ability, there are roads everywhere. Speaking of this, Qing Binghe pointed to it.

"You mean, fly over? But we're not in charge, and we don't have energy in the air. Yang Yi sneered.

"I don't talk to the mentally retarded, the IQ is scared and cancerous. Qing Binghe rolled his eyes, and then said to Cui He: "Next, we will rely on you."

"Rely on me, I won't fly?" Cui He was stunned.

"If you can't fly, just climb over! If you see a mountain or a cliff blocking the road on the earth, isn't your first reaction to climb over? Who would want to fly over? Your mind has changed too completely since you came to the mainland, right?" Qing Binghe felt a dizziness in his mind.

"Climb over, this cliff is really a bit ......" Yang Yi looked at the cliff in front of her, which was at least 100 meters high.

"Okay, okay, let me say it bluntly, Cui and you make stone steps that extend out of this cliff, use them as ladders, we are all light, we will not be discovered, slimes are creatures that live in the canyon, the top of the canyon will not go up, we just need to be condescending, it is very convenient to probe the enemy and find the prison where Qiu Lu is held, the two of you, OK?"

"Damn, I forgot that Cui He's element is earth. Yang Yi patted her head, and Cui He also looked embarrassed.

"Then what are you waiting for, act now, Yang Yi slowly moved to the side, Qing Binghe and Cui He followed, until they stopped at the foot of a cliff far away from the slimes, after all, if they were discovered by the slimes during the climb, it would be a bit fun.

The three of them sorted it out, and then began to climb, Cui He wanted to open the way, so he had to go to the front, and Qing Binghe could use the ice element to make an emergency when necessary, and make ice blades to pierce into the rock to prevent falling, so go last, and Yang Yi is naturally in the middle.

Cui He grabbed the rock wall, and a twenty-centimeter stone pillar directly extended from the rock wall, Cui He grabbed it and began to climb, and Yang Yi and Qing Binghe followed.

"It's easier than a professional mountaineer, and I used to dream of climbing Mount Everest. Yang Yi said with a smile.

"However, now our physical level is not comparable to ordinary people, even if we go back now and climb Mount Everest with climbing tools. Qing Binghe was noncommittal.

Yang Yi nodded, after all, even if they have just entered the sergeant rank, their physical strength and physical pressure resistance are a thousand times that of ordinary humans, not to mention that now they are all seven or eight sergeants.

After a while, the three of them finally climbed to the top of the cliff, standing on the top of the cliff, Qing Binghe and the others looked at the "sun" that had just risen in the sky in front of them, and remembered the situation on the earth for a while, and felt a little emotional.

"Is there a sun in this world? It stands to reason that it shouldn't be, after all, the Origin Continent is like this, and the light of one sun can't cover the entire continent at all. Cui He wondered.

"Although this is the sun of our world, it is not natural, but man-made, specially used as a light source on the continent, and there is more than one such light source, I don't know how many there are on the whole continent, and each light source is responsible for illuminating an area. Qing Binghe explained.

"Oh my God, what is the principle of this? It's man-made. Cui He was stunned for a moment.

"This is actually a star, the volume is not smaller than our real sun, but because it is artificial, it needs to be dormant, this is the 24 hours at night, and the moon you see at night is actually artificial, used to 'charge' the light source, that is, the sun, and it will also glow slightly when charging, which is almost the principle. Qing Binghe said.

Yang Yi and Cui He glanced at each other, gasped, and said, "This, what kind of strong man can complete such a great project?"

"I don't know, the book doesn't say it. Qing Binghe shook his head regretfully.

After a while, everyone came back to their senses, and Yang Yi said speechlessly: "Anyway, shouldn't we do the right thing? We came to investigate, not to see the sunrise." ”

"You have it, you have a point. Qing Binghe walked towards the edge of the canyon.

The three of them walked along the top of the canyon for a long distance, Qing Binghe's brows furrowed slightly, although his eyesight had also strengthened as a cultivator, and he could see it clearly below, but he only saw slimes appear from time to time, and he didn't find any suspected prison entrances at all.

"How can I find this, there are so many caves at the bottom of the canyon, and there are several slimes at the entrance of each cave, who knows which one is the prison?" Yang Yi said speechlessly.

"Find the strongest cave with the entrance slime, or a more remote cave without a slime guard. Qing Binghe thought for a moment and said in a deep voice.

"I can understand the strongest cave in the entrance slime, of course the prison must be guarded well, what the hell is it that the more remote cave is not guarded?"

"Because of the rebellion. Qing Binghe's words made Yang Yi and Cui He stunned for a moment, "Engel is Qiu Lu who was killed by a rebellion and sneak attack, do you think he will honestly detain Qiu Lu in prison? Now there are two possibilities, the first is that he openly defeated Qiu Lu and imprisoned him in prison and sent people to guard him strictly, and the second is that he killed Qiu Lu by sneak attack and announced to the public that Qiu Lu had an accident and became King Slime, in this case, does he still dare to detain Qiu Lu in prison?"

"Qing Binghe, how can you think so much?" Yang Yi Cui He said in astonishment.

"On the way here, I thought about the information given by the academy, and what I couldn't understand the most was that Qiulu's strength was stronger than Engel's, and Qiulu's strength was the second-tier strength. Qing Binghe muttered.

"Thinking about it this way, it is true that Engel can't win a head-on battle at all, and it is estimated that he is the Slime Kingdom that he stole with a conspiracy. Yang Yi affirmed.

"But in this case, Engel probably won't hide it in the cave on the bright surface, there should be a dark room, Cui He, how much underground can you perceive?" Qing Binghe asked.

"It's about 10 kilometers away. Cui He replied.

"So big?" Yang Yi was shocked.

"It's nothing, the detection ability of the earth element is extremely strong, Cui He, you use the elemental induction to carefully explore the rocks here to see if there are any hidden caves. Qing Binghe said.

"Understood!" Cui He chuckled, then closed his eyes and dived into the ground.

After a while, Cui He opened his eyes and said with a somewhat strange expression: "In the rock wall at the bottom of the valley more than 1,600 meters ahead, there is an area that is empty, but there is no passage, it should be blocked." ”

"It should be there!" Qing Binghe said urgently, and then the three of them ran forward.

Until the area Cui He said, Qing Binghe cautiously looked down, only to see that this place was close to the end of the canyon, and there was not a single slime at the bottom of the valley.

"Good opportunity. Qing Binghe nodded, and then signaled to Yang Yi and Cui He, and the three of them cautiously climbed down to the bottom of the valley, of course, it was also Cui He who opened the way.

"But where is the cave? Yang Yi looked at the rock walls around her and said in a daze.

"Just behind this wall, just below it. Cui He knocked on the bottom of the rock wall and said softly.

"You don't want to dismantle the stones, do you? I can do it, but my spiritual power is only enough to dismantle it at a distance of less than three meters. Yang Yi touched the density of the rock wall and said helplessly.

"Idiots with muscles in your head, I know where the mechanism is. Cui He said helplessly, and then ran to a big stone, grabbed it with both hands, and the big stone more than two meters high rolled away by itself, revealing a small hole with a diameter of one centimeter below.

"Engel is really cautious, the mechanism is at the bottom of this small hole, about three meters deep, it is estimated that only Engel's body can be extended into it, ordinary people can't think of it even if they see it, however, my element is earth, this trick is useless to me. Cui He chuckled, and under the false grasp of his right hand, an entrance directly appeared at the bottom of the stone wall next to him.

"If Cui and you are still on Earth, you are definitely the top organ and geological master, and tomb robbing or something is trivial. Qing Binghe smiled bitterly.

"Thanks for the compliment, let's go. Cui He cautiously walked into the passage, followed by Qing Binghe and Yang Yi.

After walking a distance of more than 100 meters downward, the field of vision finally widened, but the scene in front of them made Qing Binghe and the three of them stay in place for a long time.

I saw that at the end of this dozens of square meters of space, a creature was entangled by a huge iron cable, the iron cable passed through its limbs and fixed it on the wall, the three of them who looked at Qing Binghe felt pain, this creature is also a human form, the whole body is translucent and is a perfect girl body shape, long transparent hair hangs down to the waist, and there is only a pair of eyes on the face, but unlike Engel's small squint, this is a pair of very beautiful and beautiful big eyes, but these eyes are full of hollowness, without a trace of brilliance, and it looks pitiful.

"She's Qiulu, can slimes grow like this?"

"Damn, although I only have a pair of eyes on my face, I still think that I can accept it when I am a girlfriend. Yang Yi stared straight at the other party's transparent chest.

"You like it too!" Qing Binghe kicked Yang Yi's ass at the same time as Cui He.

"Hmm......" seemed to feel the movement outside, and the locked Qiu Lu's eyes had some brilliance, and he struggled slightly.
