Things are always going to get complicated.

It's like on the way to travel, you will inexplicably pick up a child who can't speak, especially the other party has a very strong ability, and then, when his big family is open to this child, he suddenly left, and left without saying a word, and just when he felt that the truth was close at hand, everything that happened told him that this was just the beginning.

Ace and Yuna speculated about the relationship between Xiao Luotai and the black dragon that sank into the sea before, and quietly followed him to find out, although they had been mentally prepared for it early in the morning, but they didn't expect it to happen so quickly.

When the two of them jumped into the bottomless hole xùe, it was pitch black in front of them, and the wind was whistling in their ears, thinking that this hole xùe had already exceeded the height of the mountain range, and then went straight to the interior of the island, and the two could only use the bounce at the rock wall to ease the momentum of the fall, and after dozens of back and forth, the two finally landed safely.

"At such a high place, the kid will be fine, right?" Yuna looked up at the place, where it was still pitch black, and not even a glimmer of light could seep in.

"Heh, don't worry, that little ghost has the ròu body of a giant dragon, and he can't be hurt by falling at such a height." Although it was said lightly, the frowning eyebrows showed the true mind of its owner, despite having a Phantom Beast Species Devil Fruit with unlimited potential like the Dragon Fruit, Luo was too young to be able to unleash its true power.

"A stinky imp who loves to get into trouble." For some reason, as soon as he saw Lotta's immature appearance, Ace remembered Luffy's character when he was a child, and he was not afraid of the ground, in short, he was an awkward little ghost.

"Look around the stone walls here. Flat and smooth, it was obviously caused by the black dragon's usual grinding of the scales in and out. The fireball condensed by Ace's fingertips finally opened up the field of vision with light, and Yuna carefully observed the nearby stone wall and explained softly.

Ace nodded, condensed the fireball on his fingertips into the air, made a simple light, and did not let go of the pothole in front of him, and after finding out that there was no danger, he and Yuna walked side by side towards the depths of the cave, suddenly the ground was faintly trembling, and the two looked at each other at the same time, and quickened their pace.

A large iron door.

At the end of the cave is a large iron gate!

"I feel more and more that this is a conspiracy now."

Ace's eyes narrowed slightly, recalling all the things in the past few days, although the time was short, all kinds of strange signs came to mind at the same time, the abnormal treasure hunt fever, the sudden appearance of the mythical creature dragon, the huge island group that can split and gather, the strange behavior of the black dragon towards the Golden Noah before he died, and the inexplicable connection between Xiao Luotai and the black dragon, as if there was an invisible black hand in the underworld to guide all this, connecting everything in series, weaving a huge net of yīn conspiracy to cover him, and he was clueless and confused.

"No matter what, let's go in first to explore the truth and reality, if there is really someone behind the scenes······ Looking at Yuna, who was a little uneasy beside her, Ace couldn't help but increase her strength when she held her hand, settled down, and finally reached out and gently pushed it, and the seemingly heavy iron door opened.

After entering, the two were stunned by everything in front of them, and what followed was a monstrous anger.

A huge glass jar filled with green sè solution, and in the green sè solution, there are also floating embryonic creatures of different shapes and sizes, all of them are asleep with their eyes closed, and from the appearance, they do not seem to be human appearances, so it can be judged that these strange creatures are likely to be the embryos of various animals.

Such scenes are not uncommon······ Of course, this is limited to Ace, who carries the memories of his past life, because in his previous life, such a scene has a name that is also familiar to the world, although it is also notorious as well as famous.

"It's a biochemical test!"

Ace clenched his fist, which had been pinched white by his knuckles, and seemed to be faintly audible crackling.

"And over here." Yuna shivered and pointed into the distance, where there were all kinds of cages, and there were all kinds of strange creatures and strange people.

If you didn't guess wrong, they were all pirates who had been attacked by the black dragon before. It's just that for some reason, they didn't die, but were placed in this underground cave that never saw the light of day.

And without exception, they were all in a coma.

"Who the hell did that?" Ace didn't want to look any further, he stared straight ahead, and was on guard, the person who could do such a thing was by no means an idle person.

"What about Mrs. Lo? No, it's too dangerous for that kid to stay here any longer, we have to find him and take him away. Bringing in everything here, Yuna resisted the strong feeling of gagging in her heart and said worriedly.

Ace nodded solemnly, now that the enemy is dark and I am clear, it is really unclear to continue to stay here, not to mention that the safety of Luo Tai is also their primary goal here.

However, just as he was about to use the Kikuichi character in his hand to free the people in the cage who had fallen into a coma, a low and slightly hoarse voice sounded out of thin air, "Don't try to do stupid things, kid······"

Ace's eyes were stunned, and he and Yuna glanced at each other at the same time, and both saw the consternation in each other's eyes.

"When you come to someone else's territory, you don't talk about the rules, young people nowadays, it's really ······"

"Don't pretend to be a ghost, since you're a senior, it's too rude not to show your true face." Ace opened the "Straight Death Ghost Eye", but he couldn't see the other party's figure, but based on the vibration in the air, he concluded that the other party was just a sound transmitted by some kind of device, and the other party himself was not here.

"Of course, it's an honor."

As the words fell, there was a loud rumbling noise in the distance, thinking that it was also a secret door, Ace and Yuna glanced at each other, nodded, and ran quickly towards the place where the sound came from, twisting and turning all the way, and finally came to a huge secret room, a man with a single piece of gold eyes was writing and drawing in a record book, and when he saw the two of them coming, he spoke.

"Ah, here you are." The words were bland and there were no other ingredients, but such understatement made the two of them more jealous.

"I'm the captain of the Black Flame Pirates, Bōtkas D. Ace, and next to me is my companion Yuna, may I ask······ You are? Ace tightened his grip on the words of Ju Yi without changing his face, and said slowly.

"I see, it's really a young man." The man smiled slightly, took two steps back, and bowed to the two of them, "Contemptible, Arkham······ As seen by the two, it is the researcher of this great study. ”

"Researcher?" Ace sneered, and a cold glint flashed in his eyes, "Study how to play nòng life?" How do you get people to have fun? Stay where the birds don't poop······"

"Birds don't? Watch your words! ”

Perhaps, as Arkham said, he is a researcher, and most of the researchers are immersed in scientific research, and they treat the precious research results as if they were their own children, and if anyone doubts this, the researchers are usually furious, and Arkham is no exception.

Anger is anger after all, and thanks to Arkham's years of immersion in those boring scientific research, his temperament has become extremely patient, only to see Arkham snort coldly, holding the pencil with his right hand lightly swiped into the air, and a wall in front of the three of them suddenly flashed with a burst of white light, but after a moment of flickering, a large screen appeared on the wall, and the scene played on it surprised Ace and the two.

On the big screen, a little boy with cherry blossom-like pink hair is snuggling up happily next to a fiery red dragon imprisoned by heavy chains, but the blood stains on the iron chain can roughly guess what kind of pain this dragon has suffered.

"Mrs. Rota?" Yuna exclaimed, and in her breath, she pulled out her gun and shouted at Arkham, "What the hell did you do to him? ”

"Huhu, miss, please calm down······ Can't you see that the reunion of father and son is such a beautiful picture! Shouldn't it be worth cheering? "Arkham is the same, but he waved his hands comically, trying to make a gesture of powerlessness." What's more, I have to thank you for this, it's all your credit, otherwise I don't know when this sneaky little ghost will come back, and then my research will not be able to make new progress. ”

Father and son reunion?

Ace didn't have much credibility for Arkham's ridiculous truth, and what he was worried about now was something else······ The dragon is a legendary creature, and some people even spend a lifetime looking for it, but they can't get a piece of the mysterious existence of scales, but on this island, two dragons have appeared one after another, and one of them is still imprisoned, which is already very strange in itself, and now coupled with the "father-son relationship" between Lockham and the red dragon, as well as those culture tank embryos in the laboratory before······ If Ace's guess is correct, then this matter is simply appalling!
