The others were dumbfounded, watching Ada's body gradually swell and thicken, and the particles of fine jade citrine all over the ground became fewer and fewer, and Long Zai cried out: "This ability ...... This ability will not be possessed until at least the fourth stage of growth-" A look of disbelief was shot in his eyes, of course he knew how difficult it was to evolve to the fourth stage of growth, and that was why he was so surprised.

There is no doubt that Ada, at this moment, has grown to the fourth stage.

The jade citrine ore that was shattered by Su Yu all over the ground was sucked into Ada's body, and his belly swelled like a ball, and the thickness of his entire body was almost doubled.

Several people looked at the jade citrine mine all over the ground in a daze, and they were actually absorbed into their bodies by Ada, they all glanced at each other, and then shook their heads, the fifth type of creatures is really magical.

Ada, who sucked all the jade citrine ore all over the ground into his body, exhaled with satisfaction and closed his mouth.

"Let......'s go," Ada's mouth opened, and as soon as he said a word, he spewed out a few grains of crystal ore and hurriedly closed his mouth.

The others saw it in their eyes, held back a laugh, and hurriedly said, "Let's go, let's go back." ”

The headache that had been bothering them was solved, but after Ada's stomach was full of crystal ore particles, its movement speed became slower, and it crawled forward while shaking, but fortunately the stone cave was spacious enough, otherwise its swollen body could hardly pass through the stone cave.

Qin Jiagui suddenly said, "What do you think this is?" ”

"What?" Meng Ting turned around, only to see that Qin Jiagui was staying in the place that had just been covered by the jade citrine mine, originally there was a large amount of jade citrine ore growing here, as this jade citrine ore was sucked into the stomach by Ada, Qin Jiagui was on the side, and inadvertently saw a piece of yellow and clear underneath, and couldn't help but step forward, and saw that under the jade citrine ore that originally grew, there was a large piece of golden looking round metal cover-like thing, and couldn't help but reach out and knock on it, making a metallic sound, but the sound was very hollow, As soon as you hear it, you can tell that the bottom is empty.

Su Yu walked over, and Long Zai also jumped down, jumped off Meng Ting's fragrant shoulder, and landed on the yellow round metal, only to see that this yellow round metal was engraved with a strange symbol, but this symbol was beyond everyone's cognition, no one knew it, including a well-informed fifth-class creature like Long Zai.

"What is this thing, I don't even know Benlong." The dragon boy touched his chin and looked like a contemplative.

Qin Jiagui said: "It seems to be empty underneath, do you want to open it and take a look below?" ”

The others also aroused their curiosity, Su Yu nodded and said, "You take a few steps back, I'll come." ”

Long Zai jumped to the side, and the others knew that Su Yu was afraid of any danger, so they let them take a few steps back, and this mysterious gold-colored round cover that suddenly appeared here was indeed full of mystery.

Seeing that everyone had taken a few steps back, Su Yu inhaled slightly, pieces of black scales appeared on his body, and as soon as his right hand was stretched, the golden claws appeared, and he inserted them into the rock on the edge of the metal round cover, and then grabbed the metal cover, and with a slight force, he felt that he could shake it.

In order to cope with possible changes, Su Yu raised his right hand and lifted the golden metal dome open.

After the metal round cover engraved with a spell was lifted, Su Yu shook his body and retreated a few steps, waited for a few seconds, and found that there was no change in the slightest, so he stepped forward and looked down, after the round cover was lifted, a circular dark cave was revealed underneath, and there was nothing to see inside, nor did he know what was inside, nor how deep it was.

"How's that, what's there?" Other people also gathered around, but it was dark inside, and nothing could be seen, Meng Ting stretched out her hand, and an eight-sided crystal floated in her hand, and at the same moment, the necklace on her neck fluttered, summoning her primordial beast "Light Ball".

Punched the power of the "ball of light" into the eight-sided crystal, making it glow, and then controlled the eight-sided crystal into the dark cavern below.

With this glittering eight-sided crystal illumination, the originally dark and lightless cave gradually revealed its true face in front of everyone's eyes.

This is a cave that only allows one person to go up and down, as the eight-sided crystals fell, everyone was shocked to find that this cave was like a dry stone well, looking at the smoothness around it, it didn't seem to be natural, but artificially made a well with a machine, its depth exceeded imagination, at least the eight-sided crystals fell all the way, and everyone didn't see the bottom, and soon the distance of the eight-sided crystals fell beyond the range that Meng Ting could control, and they disappeared, and it became dark again.

Qin Jiagui picked up a small stone on the side, put it in, and then listened to the sound, and then calculated the sound.

Finally, the sound of the small stone falling to the ground was faintly heard, and Long Tsai had already spoken: "I sensed it, it's about a hundred meters deep." ”

"What now?" Ziyu, who had a bewitching temperament on her face, opened her mouth to ask.

Everyone was curious about this cave, but it took a lot of courage to enter such a deep place, and it was dark and dangerous and unknown.

Qin Jiagui groaned: "Such a deep cave, and the walls of the cave around it are so smooth, coupled with this metal round cover engraved with strange symbols, all this is not natural, it should be artificial, there may be something in the cave underneath, but, what will it be?" ”

Su Yu thought for a while and said, "I'll go down and take a look alone." ”

Meng Ting said: "It's dark and lightless down here, how can you go down alone and can't see your five fingers?" I'll go down with you, my primordial beast 'Light Sphere' can illuminate it." ”

Seeing this, Meng Jun immediately took a step forward, looking at his frame, he also wanted to follow Meng Ting, and Qin Jiagui and Ma Ziye were more and more eager to try.

Su Yu turned his head and said with a wry smile: "It's really dangerous to go down too many people, let's go down and take a look alone, I have my own way to do the lighting." ”

Su Yu's words are not unreasonable, just the cave within 100 meters has a considerable danger, a mistake to fall down is not trivial, and after going down, you still need to climb back, although Su Yu himself is confident to deal with the possible danger, but there is no guarantee that he can protect the safety of others.

Seeing that everyone still wanted to say more, Su Yu said in a deep voice: "It's settled, I'll go and go back quickly to see what's down there." As he spoke, a dazzling golden lightning burst out from his left hand, and one after another slashed into the dark cavern, and immediately, the light of the lightning reflected inside.

Although this cave is dark, how can it bother Su Yu.

First released a bolt of lightning into the dark cave, Su Yu jumped into it.

The others looked around, and their hearts couldn't help but tighten, just jumping like this requires a lot of courage.

Su Yu slid down quickly, and then he stretched out his hands and resisted the stone walls on both sides, immediately, the speed of falling was fast and slow, under the light of the thunder and lightning of the whole body, Su Yu relied on his hands to support the stone wall to control the speed of falling, and looked down, the depth of this cave was really similar to that calculated by Longzai, about 100 meters, Su Yu quickly fell to the bottom, and jumped down with both hands.

Under this cave is a flat dark space, Su Yu lowered his body slightly, released a large amount of golden lightning, with the help of the light of lightning to observe the surroundings, found that there was another dark crack on the left side of this flat space, and split the lightning into it, with the sound of "snort", Su Yu found that there seemed to be a broader space in this dark crack.

With a slight movement in his heart, Su Yu groped his way into this dark crack, and the black scales on his whole body appeared, entering this gloomy and dark place, even he was engrossed, ready to deal with any unforeseen and dangerous situations at any time.

The space in the dark crack gradually increased, Su Yu looked around with the help of the faint light of lightning, and suddenly there was a crisp sound of "popping", as if stepping on something, Su Yu instinctively lowered his head in shock, but found that he had stepped on a white bone that was more than a meter long.

Because it was too dark here, Su Yu looked around, and really didn't look at the ground very carefully, at this moment, he suddenly stepped on a broken bone, and was busy releasing thunder and lightning, with the help of the light of thunder and lightning, Su Yu was slightly startled, and he noticed that there were a lot of broken bones scattered on the ground in this dark crack.

These bones are very huge, it seems to belong to a monster with an extremely amazing shape, Su Yu saw it in his eyes, slightly shocked, because he went deep along the dark crack that was getting bigger and bigger, and the bones scattered on the ground became bigger and bigger, and finally, he finally entered a very huge dark space, in this space, there was a huge skeleton, half of this skeleton was exposed, and the other half seemed to have merged with the surrounding mountains and rocks.

Within the skeleton of this huge skeleton, piles of strange rocks could be seen everywhere, and when Su Yu first noticed these rocks, he felt a little strange that he couldn't explain.

This huge space has come to an end, there is no other way out, Su Yu slowly walked forward, the closer he got, the more he could feel that the piles of rocks filled with this giant skeleton were strange, and finally came closer, Su Yu was shocked to feel that these rocks seemed to be born from this skeleton, and what was even more amazing was that these rocks were faintly emitted a black luster in the light of thunder and lightning, when Su Yu couldn't help but reach out and touch it, he suddenly felt a shock, and finally felt the material of this pile of strange dark rocks, seems to be acquainted, but I can't remember it.

"What the hell is this feeling, these things...... Right...... It feels ...... Although faint...... I see, it's life...... It's the feeling of life energy......"

Su Yu stroked the black rocks, and finally thought of why he had a sense of déjà vu, and hurriedly took out some time coins from his pocket.

Looking at the black time coin, and then at the black rocks in front of him, Su Yu was finally shocked to find that the materials of the two sides were strikingly similar, but the quality of the time coins was more slippery and refined.

Could it be that the Time Coin was made from these dark rocks in front of you?

An astonishing thought came to his mind, Su Yu felt his heart "thump", no longer hesitated, and immediately withdrew, he was going to go up to find Ada, and Long Zai, with the vision and knowledge of their fifth-class creatures, they must be able to recognize what this dark rock is, is his guess accurate?

If your guess is true, what an astonishing number of Time Coins will be represented by such a piece of dark rock? This time...... But it's big.

Even if he was calm in Su Yu, he felt his heart pounding, and quickly left the dark crack, returned to the cave, jumped up, and pressed his hands against the cave walls on both sides, and then kicked on the wall with both feet, alternating his hands, and began to climb up.

Su Yu's speed was extremely fast, his hands were propped up on the wall, his limbs were exerted together, and the hundred-meter-deep cave quickly climbed to the top, and then jumped up, rushed out of the cave, and fell steadily to the side.

"How's it going, did you find anything?" Everyone around was busy asking, they were just waiting on the side, worried about Su Yu's safety, and curious about what would happen underneath?

Su Yu didn't care about them, just looked at Ada, and said: "Ada, let me ask you, there are pieces of black rocks born from a huge skeleton, and there seems to be faint darkness on them, and I can sense a faint breath of life, the feeling of that material, which is strikingly similar to the time coin, I ask you, what is this black rock...... Isn't it...... Is it the raw material for making Time Coins? ”

Su Yu's words surprised everyone around, and Long Zai had already shouted: "You are talking about 'life ore'?" How can it be? You're saying there's a 'life ore' down there? ”

Ah Da's eyes widened, and he said, "What you said seems to be very similar to 'Life Ore'...... 'Life Ore' is indeed the raw material for making Time Coins, could it be that there is a 'Life Ore' underneath." Even she was amazed.

Su Yu nodded and said, "I suspect it, but I can't be sure, Ada...... No, Dragon Boy, you go down with me to see if it's true. I wanted Atta to go down, but suddenly found that Ada's was so huge, so he changed his mind and asked Long Tsai to go down with him.

Ada, however, shouted, "I see, if there is really a life ore underneath this, then this metal cover engraved with runes must be a kind of seal...... Trouble, after this seal is opened, this place will soon be discovered. ”

Meng Ting hurriedly said, "What's the matter?" What is discovered? ”

Long Zai said: "Yes, I also remembered, there are some instruments in this world that can detect the 'life ore', this seal should be to guard against this kind of instrument, and now that the seal has been opened, I am afraid that soon the person or some forces who have this instrument will find out about it, but I am afraid that other people will come soon." ”
