I open a blind box in the last days

SiZhui packed up a bag of equipment and walked towards the predetermined location under the moonlight.

"Brother Ba is here~ What, are you the only one?"

At the agreed upon location, the leader of the Blackwater Gang, Black Dog, was leading six people, and no one was carrying a backpack behind them.

SiZhui snorted coldly and said, "It's enough for me alone, you know."

"Hehehe~ It's true... Brother Ba makes a move to match one for a hundred~! Let's set off!"

The black dog waved his hand and wrapped a black cloth around his mouth and nose.

This is a characteristic of the Blackwater Gang's outings, said to be to increase their momentum.

However, from Sizhui's point of view, apart from affecting breathing, this would not have any effect at all.

Just like that, SiZhui followed the seven members of the Blackwater Gang all the way out of Dirty City and ran in the direction Black Dog said.

The reason why Sizhui didn't bring his brother was to prevent the black dog from playing tricks.

If this is a trap, he can always escape alone.

Moreover, all his brothers stayed in Dirty City, which was also a deterrent to the black dogs.

Once he dares to have bad intentions in that cave, those brothers in Si Zhui in Dirty City will be able to bulldoze his Blackwater Gang.

So to sum up, Sizhui didn't think that the black dog came up with this action specifically to deal with him.

The group of people ran and stopped all the way. After confirming that there was no deviation in the direction, they finally arrived at their destination more than an hour later.

"Hehe...the target cave is right down there!"

Black Dog stood on a bridge converted from a collapsed building, pointing to the dense forest hanging under the bridge.

"Down there? How did the gang discover such a hidden place?"

Si Zhui tightened his tight backpack and visually measured the distance from the bridge to the suspended cave.

Black Dog also ordered his men to take out the ropes from their backpacks and start processing them.

“Brother Ba, let’s see how my zipline looks like~”

Black Dog seemed to be offering a treasure and introduced the zipline to Si Zhui.

SiZhui glanced at Black Dog's proud work and snorted coldly: "The rope is not thick enough, and its toughness is also a problem. If you don't want your people to fall to death before they get in, just use the rope I brought."

Black Dog's smile froze on his face, and he tugged on his rope with some uncertainty.

"Is there... a difference?"

He felt that there wasn't much difference between Si Zhui's rope and his own.

"Hmph~ Of course there is a difference! My rope is mixed with beef tendons and has been soaked in water. You can't tell when you use your rope at first, but after it slides over a few people... it will be a disaster.

."

Black Dog had only a vague understanding of it, but he didn't take it seriously with Si Zhui.

After all, they are now allies on the same front.

SiZhui changed the rope, pulled it with his hand and said, "Okay, it's much stronger now. You get off first, and I'll go in the middle."

Black Dog grinned and made a gesture, asking one of his men to take the lead in hanging the hook and lock and sliding down.

Since the person they want to deal with is hidden in the cave, they must ensure absolute silence during this operation.

After several people slid across the ropeway, Black Dog specially sent a subordinate to guard here.

The rest of the people ducked into the inconspicuous hole, lit the emergency lights and began to explore inside.

Originally, after entering the cave for the first time, the group turned on the emergency lights. But after walking for a while, they discovered that the inside of the cave was much larger than it looked from the outside! Moreover, it was surrounded by light refracted in from unknown sources, making the cave look bigger.

Some strange minerals in the cave illuminate it, like guiding lights.

"Wow...it's so beautiful inside...I can't believe there is a cave like this..."

Black Dog and the others looked at it with their eyes a little straight. Only Si Zhui saw the danger hidden everywhere inside!

"Be careful, don't stand on the edge! Those seemingly hard lost coins are very fragile!"

As soon as Sizhui finished speaking, a member of the Blackwater Gang guessed a loose stone and almost fell down.

"Those are sedimentary rocks. They are very fragile. Just be worried and don't make any noise!"

Hei Gou was puzzled after hearing Si Zhui's words.

"Brother Ba, how do you know this?"

"My mother told me..."

"Your mother?"

Hei Gou remembered that Si Zhui's mother was the scary woman with one eye and a flat head who was known as "the most unprovoked person in the whole dirty city"!

The group of people continued to move forward, but the black dog accidentally or unintentionally fell behind Si Zhui.

He had made a good calculation, knowing that Si Zhui knew a lot, so he didn't act like a hero and went to the front.

However, the further the group walked, the more surprised they became, and the more timid they became...

After going through two turns, the area of ​​this cave actually became larger again! This guy... feels like he can fit the entire Lingyun City into it!

SiZhui observed the surrounding terrain, combined with the idea knowledge his mother taught him, and compared the nouns one by one.

Looking at the stone pillars of different sizes and shapes in the east, SiZhui guessed that they must be the stalagmites, stone buds, stone flags and other cave accumulations in the cave that his mother mentioned.

My mother also said that drinking the stalactite liquid hanging upside down can cause certain changes in the human body!

Of course, Sizhui would not be stupid enough to drink it himself, but he still put some in the aqua regia bag and planned to go back and conduct experiments on animals.

At this time, after everyone walked down a secret passage again, they found that there were suddenly more roads in front of them.

Those caves are criss-crossed with stone peaks, flowing water, intermittent ponds, and underground lakes staggered in between.

But... which way should we go?

"Black dog, which way are you going?" SiZhui asked bluntly.

Hei Gou didn't care. Anyway, he still needed Si Zhui's knowledge here.

He raised his head to one of his men, who took off his backpack and found a palm-sized instrument from inside.

"Hehe~ This is a high-end gadget that I spent a lot of money to get from Lingyun City~! We will use it to scan where the key points of these passages lead..."

Black Dog looked proud and asked his men to start the operation.

Looking at the device with the screen on, SiZhui really didn't expect it.

It seems that Black Dog has been preparing for this day for a long time.

After the magical device is turned on, it emits green light as thin as a hair.

These rays scan back and forth in the surrounding channels, seemingly collecting data.

Black Dog looked around. He said with a relaxed expression: "Let's look around. It will take a certain amount of time to scan and collect information."

SiZhui did not wander around like these Blackwater Gang members, but walked towards a stalactite that was emitting colorful light.

He was a little confused, why was it that the Black Dog gang turned a blind eye despite the brilliant glow here?

"strangeness...."

SiZhui muttered as he arrived at the center of the colorful light.

The source of this colorful light is a stalactite that is as thick as a millstone but has a sunken center.

What makes SiZhui feel absurd is that in the center of this colorful glow, there is a... box??
