I can push my cultivation progress to the end

Li Hai first took the metal box, which resembled a metal lump, and brought it close to his eyes, searching every inch for any traces of writing.

Unfortunately, there were no markings whatsoever.

Not only were there no markings, but the keyhole on the iron box, perhaps due to the passage of too much time, had also deformed and compressed into a tiny slit, so narrow that even an embroidery needle couldn't penetrate it.

Not only was the keyhole like this, but even the gaps between the iron box's doors were visibly deformed, twisted and pressed against each other like ugly scars.

"Let's pry it open and have a look."

With this thought, Li Hai used both hands, grabbing the sides of the iron box and exerting force suddenly.

Instantly, two opposing forces, each with hundreds of thousands of pounds of strength, were applied to the sides of the iron box.

Buzz—

In that instant, the surrounding lake water rippled in layers under the oscillation of this unparalleled force.

Yet, even under such astonishing power, the iron box remained unchanged, without even a slight tremor, as if the force applied by Li Hai was fake.

From this, it could be inferred that this iron box was definitely not made of ordinary steel, but of some unimaginable, unknown material.

"Damn it! Are you made of Adamantium?! So light, yet so hard."

After cursing, Li Hai ignored the iron box and picked up the crossbow.

"I'll deal with you later; let's look at something else first."

While muttering, he glanced around and noticed two ancient篆 characters engraved in a small corner of the crossbow arm—"逆乱" (Nìluàn).

"The 'Rebellion Bow'?"

A guess formed in his mind.

To verify his guess, Li Hai pulled back the bowstring.

Whoosh—

Instantly, everything in his field of vision became completely clear.

No, it should be said that it became completely bright and transparent.

All the inanimate objects and living creatures in all directions were clearly visible to Li Hai.

For example, looking diagonally upwards, his line of sight could easily penetrate countless tons of dark lake water and layers of thick rock, clearly seeing the villagers of Yu Family Village who had already stood up on the lake shore from a bottom-up perspective.

According to Li Hai's rough estimate, this extremely deep and distant distance might be several thousand feet.

In other words, as long as he held this crossbow and drew the bowstring, his perspective range would be ten thousand meters in all directions, or even further.

And all physical matter within this range would be unable to block his line of sight.

How terrifying.

"But what's the use of having a bow without arrows? Could it be that I have to… fire it empty?"

Thinking this, Li Hai tried pointing the crossbow diagonally upwards, aiming at the old village chief who was speaking loudly to the villagers on the lake shore a few hundred feet away, and released the bowstring.

Swish—

Suddenly, an invisible and intangible force that Li Hai was extremely familiar with appeared out of thin air in the arrow groove, and the moment it appeared, it burst out of the crossbow and shot straight towards the old village chief on the lake shore.

In the next instant, the old village chief was accurately hit by this invisible arrow, and at the same moment, his nose, ears, hands, and feet were all interchanged and reversed. Then, he lost his balance and sat down on the ground, and then, as if he had pressed something, he jumped up with a painful howl.

Li Hai, deep in the lake, saw this scene and immediately understood:

"So that's how it is. The so-called 'long tongue in the chrysanthemum' curse that shrouded the entire Yu Family Village was shot out with this crossbow. The old man was so painful after sitting on the ground because he was pressing on his tongue."

After understanding this truth, Li Hai couldn't help but shake his head and chuckle, but then he thought of another question:

"Then, how should this curse be lifted?"

Thinking, Li Hai picked up the Rebellion Bow and aimed it again at the old village chief on the lake shore, whose hands and feet were still interchanged, and fired.

"…"

No invisible arrow appeared.

But the old village chief on the lake shore returned to normal in the blink of an eye.

The interchange and reversal of his nose, ears, hands, and feet, which had caused him so much pain and discomfort, all disappeared completely, as if they had never existed.

"Huh? What's going on?"

Confused, Li Hai picked up the Rebellion Bow again and aimed it at him, drawing the string again.

But… the invisible arrow still did not appear, and the old village chief on the lake shore, who had returned to normal, remained normal, and no abnormal situation occurred.

"What's going on?"

In confusion, Li Hai aimed at the old village chief and fired more than a dozen times in one breath.

But there was still no reaction, whether it was the crossbow or the old village chief.

"I understand."

Li Hai grinned, "This thing actually has a cooldown. After using it once, you have to wait a while before you can use it again, but dispelling the curse seems to have no restrictions; just fire an empty shot at the cursed target to dispel it."

At the same time, he also understood why the Salt God had never used the Rebellion Bow again after using it once, until he died.

Simply because the cooldown time of this bow had not passed.

What an unlucky fellow.

In short, after thoroughly understanding the specific function of this crossbow, Li Hai prepared to put it into the Guiyou Cave Heaven.

But suddenly…

"Wait!"

Li Hai's movements suddenly stopped, "Could I, use the perspective function of this Rebellion Bow… to see what's inside that iron box?"

Thinking of this, he suddenly became excited, and then he held the crossbow and drew the bowstring, aiming at the overly hard iron box.

"It worked, I can really see it!"

Li Hai's face was filled with joy as he stared at the iron box.

In his current field of vision, the inside of the iron box was clearly visible.

However, the scene inside the box was different from what Li Hai had imagined.

There were no high-tech weapons or armor inside, only dozens of thin, polygonal disc-shaped objects of various colors, similar to large CDs.

These unknown polygonal discs were all piled up randomly inside the iron box, some still intact, while others were already broken.

"It feels a bit like a USB drive."

Li Hai muttered, "Could it be used to store some kind of data?"

While muttering to himself, he saw rows of text, either blurry or clear, similar to labels, on the surface of these discs.

Li Hai first looked at the ones piled on top, and on the surface of these disc-shaped objects, it was clearly written—

"《Wuxian Federation Military Intelligence Research Lab… File No. 1》"

"《Poorqi Sea Area No. 4 Prehistoric Civilization… Research Records》"

"《Yunding Plateau No. 8 Prehistoric… Relic Archaeological Research Records》"

"《Pixiu Mountain Range No. 5 Prehistoric Civilization… Research Records》"

"《Quafu River Bottom No. 6… Relic Archaeology…》"

"What's going on here?!"

Li Hai's face was full of confusion and shock, "Isn't the Wuxian Federation already a prehistoric civilization? How can there be… prehistoric civilizations before them?

And… what are these No. 4, No. 8, No. 5, No. 6 relics? Are there so many prehistoric civilizations? Where did they all go?"
