Following the smell, Ying Zhen and Gu Jin walked through the tunnel to a cliff, although it was still in the desert, but there was a natural spring here, which was in stark contrast to the barrenness on the ground. In this bottomless pit, only a faint light reflects the humid air, making the place extremely eerie. Where was there any soil here, dark purple rocks replaced the sand of the great desert, and when they reached the edge of the cliff, they found that there was a long staircase leading to an unknown hole, emitting a faint blue light, and the closer they got there, the stronger the smell of ancient and modern smells.

The closer you get to the entrance of the cave, the more humidity gets heavier, and there is a lot of moss growing on the floor and walls, which shows that there is plenty of water here. Entering the cave, the scene inside is really amazing to Ying Zhen and ancient and modern, the whole room is like a round plate, every three or four meters there is a torch, flashing blue firelight, in the center there is a vessel made of crystal, placed on a high bulge, I don't know what; Next to the crystal vessel was placed a tall dark purple cage, I don't know what was imprisoned inside, I looked forward, it was a curled spirit beast, standing up about thirty or forty meters, it was not as snow-white as the ancient and modern body, the skin was like a cracked earth, the long claws were dark and black, the ears were very long, and it could be seen that it had sharp teeth.

"Ancient and modern, what kind of thing is this, it looks like a monster in Ultraman, weird." When he first saw this spirit beast, Ying Zhen couldn't help but gasp, after watching it for a long time, he felt that it was not so terrible, and when he observed this end, he couldn't forget to complain a few words about Ying Zhen's character.

Gu Jin first moved his swarthy and small nose, sniffing something, and then his eyes widened, "It's... It's the spirit beast we've been looking for! ”

"Really? Is it alive or dead? And why are you here? Ying Zhen's brain exploded when she heard the news, and a series of questions popped up.

"I originally thought that this spirit beast ate those people in the desert, but now it seems that it is imprisoned here, and it is unlikely that it will commit a crime, that is the person we saw before that snake eats, alas, it really shouldn't be let go......" Gu Jin was still complaining to himself, as if he remembered something, and said: "By the way, I don't feel a trace of anger in it, it must be old and dead." ”

"Why is it said that it died of old age, there is no other possibility?" Spirit beasts can live for so long, if they die of old age, then how long does this cave have to be old?

"First, there were no wounds on its body and no signs of poisoning. Second, no one should know about this hole, and no one will come, so how can there be other ways to die. "Ancient and modern look like a matter of course.

"So why is it here? Shouldn't spirit animals like it all live in groups and be with other people of the same kind? But we just walked all the way, and we didn't see such a spirit beast. "When Ying Zhen encounters spirit beasts, he meets a large group of them, but it is the only one here, and Ying Zhen really can't think of other possibilities. Could it be that it is trapped here?

"That's what you said, so in the current situation, there is only one possibility." Gu and Jin deliberately didn't say it, leaving a suspense, and I had to ask Ying Zhen to talk about it.

"What?" Ying Zhen was very curious.

"That's something that stays here as a guardian beast to guard here, it's really strange, it stands to reason that where there is a guardian beast, there should be something to guard, was it taken away by someone else? Then there should be some clues, so clean......" Gu Jin was still pondering, and Ying Zhen said disdainfully:

"What kind of guardian beast, I think it's your nonsense, you just want to save face...... Yes! Before the words were finished, Ying Zhen was speechless when he heard the nonsense of ancient and modern times, leaned back, this lean, and broke the crystal vessel, Ying Zhen really felt embarrassed at this time, and did some stupid things for Mao himself~

"Well, what's that, I didn't know it was so easy to break ......" The voice became smaller and smaller, I thought that Gu Jin was going to talk about himself endlessly again, but Gu Jin's alert consciousness told it that things were not so simple.

Just two or three seconds later, the entire cave wall began to tremble, and with a "boom", the scene in front of him flashed the titanium alloy dog eyes of someone and a certain fox. My God, there is still a moss rock on the wall in front of me, completely turned into a bookcase, in fact, it is just a horizontal bar that can put books, and this bookcase is not ordinarily large, the whole wall is embedded with such horizontal bars, and the number of ancient books on it is enough for tens of thousands, it is simply an ancient version of the library!

"I see." Ancient and modern are really confident enough, so why is it always a picture of Detective Conan's sense of déjà vu.

"Which one? Which? Ying Zhen can be said to have watched the whole process with a confused face.

"Ugh." Gu Jin put on an expression that your IQ was worth worrying, and then explained in detail: "The maker of this cave is quite clever, and deliberately put a crystal vessel here in order to divert the attention of the thieves. ”

"They would never think that this vessel was the mechanism for what they were looking for, let alone destroy it, only how to steal it, would they?" Ying Zhen has some clues.

"Yes, I've made progress with me." Gu Jin first showed a look of appreciation, and then said: "Secondly, when you break the vessel, I feel that something is wrong, generally speaking, ores like crystals, diamonds and other ores should not be very hard, even if it is fragile, it is still a stone, and it will not break if you press it." ”

"Oh, I see." Ying Zhen is really a long knowledge.

Gu Jin walked down the stairs on the side, walked to one place, casually pulled a book next to him, and then showed a look of surprise, "Ying Zhen, come on, these books are all long-lost cultivation secret methods, and we have earned them this time." ”

Ying Zhen didn't think so, and walked up unhurriedly, "Alas, so what, do we have a way to take them all away, do you know how many books there are here?" ”

"That's true, but I'm sure we'll regret any of the books here if we miss them." Ancient and modern faces of pity.

Gu Jin seemed to think of something, and quickly ran to the spirit beast imprisoned in the cage, Ying Zhen hurriedly followed, Gu Jin stood in front of the cage, and said to Ying Zhen behind: "Don't worry, even if you don't want these books, I will help you get them!" ”
