All morning, the four siblings stayed in the warm mountainside garden, enjoying the cosy weekend.

After lunch, after a short rest, Ou Zhou and Jiang Yang took the dragon balls, and together with Shui Jingxin and Ke Fei'er, they went down to the waterhole under the waterfall on the side of the garden and dived into the secret passage.

Ou Zhou and Jiang Yang held the dragon ball illumination, got out of the water, and stepped on the stone steps to the vault of the former biker party's main altar again.

Shui Jingxin wanted to test the power of the seventh ice mystic energy, so he volunteered to push the one-meter-thick vault stone door.

She stood in front of the stone gate and took a horse step, her palms were full of ice power, and she used her strength to push the stone gate.

Chirping, the stone door slowly opened, and after continuing to exert force, the stone door had been completely pushed open.

Shui Jing took his inner breath and stood up.

The three of them applauded in unison.

Ke Fei'er smiled: "The water chick who used to be weak and couldn't help the wind has become the water four heroes at this moment." In the future, we will call ourselves the guardians of the Xuanji Sutra. ”

"Who's going to be the boss?" Shui Jingxin asked seriously.

"Let's go in and talk about it." Koffiel took the lead and entered the vault.

In the vault of nearly 300 square meters, only the empty chests that were once filled with gold, silver and jewelry remain. But the great pearl of the night on the vault dome is still there, so the light in the vault is still there.

At this moment, the heavy stone door closed silently behind them.

Everyone walked around and saw that the cages were empty.

Ou Zhou couldn't help laughing and said: "Jin Cheng and Liao Yunhui, the two helmsmen, searched and scraped clean, and they almost got these valuable sandalwood boxes out and sold them." ”

"It's really unthinkable that the biker party has been working hard for hundreds of years, and the huge treasures they have saved are actually prepared for the great cause of Xuanji Jing. Things in the world are really mysterious! Jiang Yang sighed.

Ou Zhou nodded and said with a smile: "From a certain point of view, the contribution made by the Biker Party to the cause of Xuanji Jing is no less than that of our senior brothers!" ”

"Having said that, the treasure they have amassed is ill-gotten gain, and every box and piece may be stained with blood!"

"Pirates make a living by looting, and burning, killing and looting are their main means of accumulating wealth. Those who can amass gold and silver jewels are definitely not good birds. ”

"Man dies for wealth, and birds die for food. It's nothing more than big fish eating small fish, and small fish eating dried shrimp. ”

"Okay, junior brother Ou, senior brother Jiang, stop sighing about how the treasure came from. Let's discuss and discuss the mystical scriptures, who is the boss and who is the youngest, right? Shui Jingxin urged.

"Pretty sister, you're the proposer, can you say it first?" Jiang Yang sat on a sandalwood box.

"I'm just talking about it. Your senior brother is the heir of the Xuanji Sutra, and you two have the final say in everything. There's no point in discussing the big and the young. ”

Ou Zhou said with a smile: "Aside from the mystery scriptures, simply talking about the size is already a matter of self-determination, and there is really no point in discussing it." ”

"Hahaha, you're right, what's the matter, you two are younger brothers, Brother Ou, Brother Jiang, it's not obvious at a glance!"

"So, you don't have to line up any big sister or younger brother." Ou Zhou kicked a box, but the box didn't move.

"Huh?" In astonishment, he leaned down and moved with his hands, but still didn't move.

Shui Jingxin, Jiang Yang, and Ke Fei'er also came over to see the strangeness.

Ou Zhou suddenly had a flash of inspiration in his mind, and instead of moving the box, he lifted the lid of the box to see inside.

The inside of the box was empty, and the gold, silver and jewelry had long since been emptied. He bent down and leaned into the box, tapping his fingers at the bottom of the box, and there was nothing unusual underneath.

He knocked again at the bottom of the box, but he didn't hear any difference.

Everyone looked at the strange wooden box, the dark wood was tinged with a faint purple, and the corners were wrapped in bronze.

Ou Zhou and Jiang Yang glanced at each other, and the two of them grasped the two corners of the wooden box as if they understood, and tried to turn it clockwise, but it didn't move, and then turned counterclockwise, this time it moved.

I saw the stone wall behind the wooden box, and opened a door silently.

Everyone was shocked, Ou Zhou took up the cave and explored the subtle method, and there was nothing dangerous in it, so he stepped in.

Inside is a tunnel, only wide enough for two people to pass side by side.

Every few tens of meters on the cave wall, there is a night pearl in a one-meter-high groove, which makes the light in the cave shine.

The four siblings followed suit, and their curiosity followed their footsteps and moved forward all the way. Although the cave is dark but not damp, it is obvious that there are good vents.

The tunnel slopes downwards and has steps at key points.

After walking for about five or six minutes, I came to a stone wall, where it was obvious that we had reached the end.

Ou Zhou and Jiang Yang took out the dragon balls and looked carefully on the stone wall respectively, looking for any mechanism that could open the stone wall.

On the dim stone wall where the light of the night pearl does not shine, there is a looming stone pattern, which at first glance is no different from the rest of the stone wall.

But at this moment, under the light of the Dragon Ball, when you look closely, that position is slightly smoother than the other parts.

Ou Zhou rubbed his palm on it, and first pushed it in, but failed. I pressed my palm against it again and tried to turn it counterclockwise, but to no avail. Finally, when it turned clockwise, a door opened silently on the stone wall.

The four sisters and brothers looked at each other in surprise, Ou Zhou was the first to step into the stone gate, and when he came out to see, he couldn't help laughing.

Jiang Yang Ke Fei'er Shui Jing heard the laughter, and after stepping out of the stone gate and looking back, he immediately smiled happily.

"It's really hard to find a place to break through the iron shoes, and it takes no effort to get it. Who thinks that the secret passage of the vault turns out to be this big freezer in the kitchen! Ou Zhou pointed and smiled.

Indeed, this is the kitchen freezer in the suite where Ou Zhou and Shui Jingxin live.

"No wonder I've been looking for it before, but I can't find it, who would have thought that such a freezer full of all kinds of fresh fruits and vegetables would be a trick." Jiang Yang couldn't help but wonder.

"Damn the helmsman of the bikers, how much thought did it take to think of such a wonderful mechanism?!" Shui Jingxin burst into foul language.

Ke Fei'er smiled and said, "It turns out that all the gold, silver and jewels were sent to the vault from here by the helmsmen of the past generations. The secret passage in the waterhole was designed to deal with accidents. ”

"But, was there such a big freezer a hundred years ago, even if this thing was specially made, it wouldn't be more than fifty years at most?" Shui Jingxin questioned.

"In fact, this freezer hasn't even been for thirty years." Kefeier said.

Shui Jingxin became more and more confused: "However, the secret passage and the vault were obviously dug at the same time, and this freezer is no more than thirty years old, this reason doesn't make sense?" ”

"Hahaha, here's the clever part," Kefier pointed to the kitchen and everything, "you see, this kitchen, living room, bedroom, everything is not modern, it has to be the same as it was a hundred years ago, how can it look nondescript!" ”

"Oh, I seem to understand a little, they call it keeping up with the times. From the very beginning of the design of the vault and the secret passage, the issue of renewal has been taken into account. The purpose is to make people unsuspecting. ”

"Yes, exactly." Koffiel laughed.

Ou Zhou wondered for a long time, and said at this moment: "It's really a clever move, and it actually concealed the subtle heart method of the cave detective." I've carefully checked the kitchen before, and I haven't let go of this freezer, who would have thought, the more things on the surface, the more clever they are. ”

"What kind of position was it thirty years ago?" Jiang Yang is puzzled.

"It's probably something that is closely related to the kitchen." Ou Zhou said with a smile.

"How do you lock it up?" Shui Jing looked at the freezer curiously.

She reminded everyone in one sentence, and Ou Zhou and Jiang Yang began to look for a way to close the tunnel entrance.

Every object in the kitchen, even every inch of the wall, Ou Zhou had inspected before, and there was no button to open the tunnel entrance.

After Ou Zhou thought of this, he did not look for it again, but opened the freezer to look.

The door of the freezer is the light switch, which turns on the light and goes off when it is closed.

In addition to this, there is also a row of knobs in the freezer to adjust the temperature, which is nothing more than refrigeration and fresh-keeping defrosting and the like.

Ou Zhou tried them one by one, but there was no response.

"Hey, that's weird!" He couldn't help but scream.

At that time, Jiang Yang was looking for other places in the kitchen, saw it, and asked, "Senior brother, what's wrong?" ”

"I can't find it, where is the mechanism to close the tunnel entrance?"

Shui Jingxin said with a sense of enlightenment: "This kind of design is full of surprises, and the more obvious the object, the more suspicious it is. ”

After Ou Zhou heard this, his heart moved, and he reached out to touch the lampshade in the freezer, he first tried to press it up, then rotated it left and right, and the freezer really moved, and began to slowly close towards the mouth of the tunnel.

He closed the freezer door and said with a smile: "Grandma is a bear, it turns out that the lampshade in the freezer is the mechanism." The more conspicuous it is, the more clever it is! ”

Everyone was relieved and couldn't help laughing.

Ou Zhou smiled and said, "I was curious before, only the chief helmsman of the biker party lived in this suite, why the freezer was full of ingredients. It feels as if there are often several people dining here. Thinking about it at this moment, it is clear that there are no three hundred taels of silver here. ”

"But, why do you want to store so many ingredients when he lives here alone?" The water meditation was puzzled.

His purpose is nothing more than to hide people's eyes, first, to make people feel that there will be many people dining here, and second, to make the freezer run normally. If an empty freezer is placed here, and then various functions are turned on, wouldn't it seem redundant, isn't it a bit like wanting to cover up! ”

Ke Fei'er nodded and said with a smile: "In short, the previous doubts have now been solved. It's just that although we know the secret passage of the vault, there is no treasure to store in it! ”

"Extreme wisdom, such a perfect treasure trove, and the creation of this luxurious manor, it was originally prepared for the Xuanji Sutra. In this way, the founder of the Biker Party must have an inseparable relationship with Dao Ancestor, otherwise how can all this be explained! Ou Zhou said thoughtfully.

It makes sense, Daozu knows that modern science and technology research and development need a lot of funds to do funds, and a good environment is needed as a base, so the forward-looking arranger began to prepare a century in advance. And we didn't accidentally bump into such a great thing, everything was actually under the control of Dao Ancestor. Jiang Yang said.

"Hey, hey, hey, in short, everything here, we are enjoying. The predecessors planted trees and the later people enjoyed the shade, and we can be regarded as giving full play to it. Shui Jingxin smiled.

Ke Feier looked at the time and suggested: "The mystery is solved, it is not too early, there are ready-made ingredients here, let's prepare dinner!" ”
