Zhang Fan patted the hibiscus, leaned her against the edge of the passage, and got up and walked to the stone pillar to check.

The stone pillars were rough, as if they had been polished with some kind of tool, and some of them were still connected to the stones on the side of the passage, and there were some strange patterns on them.

Zhang Fan looked at these lines and seemed to be a little familiar, but he couldn't think of what they were, so he reached out to touch them, but he didn't find anything unusual.

Who would have carved a half-finished stone pillar here?

After thinking for a while, Zhang Fan felt that the air seemed to become thinner, obviously because the oxygen content in the air was insufficient.

If he doesn't find a way to leave, he and Hibiscus will soon die here.

What to do? Zhang Fan looked at the dim lamp, it seemed to be a little dim, and the little hibiscus next to him was also looking at it.

No matter what, you have to find a way.

Zhang Fan began to look around the passage, kicking a few times from time to time to see if there was a hollow place.

It's frustrating that everything is sturdy and doesn't look like there's a hidden exit.

Seeing Zhang Fan busy, Xiao Hibiscus stood up against the wall, and walked to the stone pillar with the lamp to watch carefully.

Suddenly, she said:

"Brother, do you think this looks like a dragon totem?"

Zhang Fan stopped his movements, hurriedly walked to the side of the stone pillar, and looked at it carefully, recalling the huge dragon totem he saw in that square when he was in the Dragon Tooth Star, compared with the one in front of him, it was really a little similar, no wonder he felt a little familiar just now.

It's just that the trumpet in front of him is too rough, if it weren't for Xiao Hibiscus talking about it, Zhang Fan would just feel familiar, and he wouldn't associate it with the dragon totem at all.

"It's kind of like that." Zhang Fan said.

"If it's a dragon totem, how can it be here?" Hibiscus asked, puzzled.

Zhang Fan shook his head and said:

"I don't know, could it be that the people who used to have dragon teeth were also trapped here? Carved a dragon totem before dying? ”

On second thought, this idea seems a bit ridiculous, so why else?

I don't understand, Zhang Fan slapped the stone pillar in annoyance, but he never thought that with such a slap, he actually slapped the stone pillar into a piece.

"Huh?"

Zhang Fan quickly withdrew his hand, then took the lamp in Xiao Hibiscus's hand, and approached to take a picture of the place that was photographed by himself.

Sure enough, the inside of this stone pillar is hollow, and there seems to be something hidden in the middle.

Zhang Fan took a step back, raised his leg and kicked the stone pillar violently, until the stone pillar was completely shattered, revealing two things inside.

A long knife, and a metal cube.

Zhang Fan stretched out his hand and held the long knife in his hand, the black scabbard was inlaid with golden patterns, and the whole knife was only three fingers wide even with the scabbard, which was very handy.

Zhang Fan pulled out the knife, the cold light flashed, and the sound of golden chimes was long, endless.

"Tang Dao?"

Zhang Fan could see at a glance that this knife was very similar to Xu Zhen's.

It's just that the gauntlet of the knife in Zhang Fan's hand is slightly larger, and the jaw of the knife is a dragon head, surrounded by dragon patterns on the knife body, and the tip of the knife is slender, Xu Zhen's knife is more concise, and the tip of the knife is the same as the fracture.

Zhang Fan had a horizontal knife in front of him, and looked at it carefully for a while, while thinking about how there could be a Tang knife in this place, and this knife did not look ordinary.

At this time, Zhang Fan's gaze happened to fall on the jaw of the knife, and four small dark red characters came into view.

God-King Blazing Sun

Zhang Fan trembled and almost threw the knife out of his hand.

"It's ...... The weapon of one of the twelve god kings in the legend? ”

How could the God-King's weapons be here?

God King Lieyang, God King Lieyang......

Zhang Fan stared at the knife while muttering the four small words in his mouth.

"Brother?"

The little hibiscus next to him patted Zhang Fan lightly, and then he reacted, put away the knife and sheathed it, suppressed the excitement in his heart, and went to look at the metal body again.

Zhang Fan grabbed the boxy metal body with both hands and picked it up from the rubble, and there was nothing special about it in his hand, and it was not sinking.

Zhang Fan took a look, this metal body is a standard cube, the side length is less than half a meter, five of its six sides are black, and only one side is as crystal as inlaid with a piece of crystal.

"What is this?"

Zhang Fan brought the metal body to the lamp and carefully looked at the side with the crystal.

There should be a layer underneath the crystal that is hollow, as there is some powder-like stuff in it, and the powder seems to be still moving.

It's just that when Zhang Fan looked closely, the powder stopped shaking again.

"Girl, you've seen this ......"

Zhang Fan was just halfway through his speech, only to see that the powder began to shake again.

"Huh?"

Could it be that as soon as there is a sound, the powder will move?

Zhang Fan motioned to Xiao Hibiscus not to speak, and he watched quietly.

Sure enough, the powder was still.

Zhang Fan gently lowered the metal body to the ground, or patted it gently, and as long as it made the slightest sound, the powder would shake.

And they will be arranged in different shapes or patterns depending on the sound.

"Klarney Geometric Locks?"

Zhang Fan suddenly realized, and suddenly remembered what this thing was, a long time ago, when he was still in Bibo Star, he had come into contact with information about Krani Geometric Lock, but he had never seen the real thing.

It is a mechanical lock that is opened by recognizing the frequency and waveform of the sound vibration, and the different frequencies can make the powder arrange into various patterns, and as long as the pattern is the same as the set unlocking pattern, the lock can be opened.

But the chicken side is that if you only need to use sound as a secret key, then intelligent recognition technology has been around since ancient times, and you can't afford to use Krani geometric locks that are extremely complicated to make and have an extremely bad user experience.

So, this thing was only a flash in the pan in history, but it was recorded because of its brilliant design.

If you have to talk about its advantages, in addition to the design that is full of support, it is that it is very difficult to crack, and it is all composed of machinery.

But for the grumpy acutes, anything sophisticated is a hammer deal in front of them.

Zhang Fan is not an acute child, but the oxygen content here will not wait for him to slowly crack it.

And no one knows if after opening this metal body, it will be as expected, there is something life-saving inside.

Zhang Fan put the metal body on the ground, took two steps back, drew the long knife again, and slashed it without saying a word.

To Zhang Fan's surprise, the metal body, which looked extremely the outside, was actually shaved off the crystal side like a piece of paper under a knife.

The powder was scattered all over the ground, some small parts were also jumping everywhere, and the long knife easily cut into the ground more than half a meter deep.

"So soft?"

Zhang Fan was speechless for a while, put away the knife, picked up the metal body without a lid on the ground, and saw a note and a small wooden box inside.

Zhang Fan took out the note and looked closer to the dimmer light.

"I'm the president of Mitsui Kaisha, Hideyoshi Mitsui, no matter who you are, since you can open this only surviving Krani geometric lock, and see this note, it means that you are a smart person."

Zhang Fan smiled, the only one who survived? Now it doesn't exist, keep looking.

"Presumably you also got the Sun Knife, it is the Sun King's saber, I found it from the Lost River, you keep it first, and then bring this small wooden box to me, remember, don't try to take a look at the contents."

The note hadn't finished reading yet, but Zhang Fan was very curious about what was in the small wooden box, so he picked it up.

Don't try to take a look at what's inside?

This sentence is like a tweeter on the side of Zhang Fan's ear, constantly shouting loudly, open it, and take a look.

"Let's take a look, then."

The wooden box was very light, and with a flick of Zhang Fan's fingers, he opened the lid of the box, and inside was a small golden cloth bag.

What could it be? Zhang Fan curiously opened the cloth bag again.

A semi-circular object lay quietly in a cloth bag, only half the size of a palm, and the whole body exuded an indescribable color, Zhang Fan had never seen such a color.

It looks like green but not green, like red and not red, faintly, how to look, the color is very bright, but if you look closely, if there is nothing.

It's hard to explain what the human eye can see, depending on the wavelength of light, which is between 380 nanometers and about 740 nanometers, which is visible light.

Zhang Fan is sure that there is no problem with his eyes, and the colors in the visible light spectrum have basically been clearly classified and defined, are these colors in front of him not within the range of visible light? So why is it obvious to see?

Zhang Fan hesitated to reach out and touch it, and Xiao Mu Hibiscus said weakly on the side:

"Brother, I feel so sleepy."

Zhang Fan immediately came to his senses, rewrapped the cloth bag, covered the wooden box, laid the small hibiscus flat on the ground, and then hurriedly looked at the remaining words on the note.

"If you're trapped here, it's easy to get out, use the Sun Knife to split the boulder behind the pillar, and there's a passage over there. If you haven't been trapped here, get out of here, and remember, bring me a little wooden box, it might change your life. ”

"Inexplicably, since you want someone to bring you something, what are you doing in such a water cell?"

Zhang Fan complained a few words speechlessly, there must be some mechanism in the notebook in the study, and as soon as he took it, the water in the pool would skyrocket.

But if you don't take a note, you can find it here, and if you're lucky, you can get this Sun Knife, which is completely an act of taking off your pants and farting.

As for changing his life or something, Zhang Fan was not interested at all, he pulled out the Sun Knife and slashed the letter at the boulder behind the stone pillar suspiciously.

The Sun Knife was like slashing on a piece of tofu, and there was not much resistance.

"A good sword, worthy of the saber of the god king."

Zhang Fan sped up the speed of the chopping, and it didn't take long for him to open a hole more than a meter deep in the boulder.

With another knife, it seemed to split through the boulder, because Zhang Fan heard a strong whirring sound.

It's just that something seems to be wrong, how does this look like I'm blowing the wind outside?

After being stunned for a moment, Zhang Fan scolded angrily:

"I'll go to your uncle's Hideyoshi Mitsui."

Then he picked up the little hibiscus, and regardless of how thick the stone cave was from the outside, Zhang Fan used all his strength to crash towards the place where a gap had been split.
