Instead of rushing back, he continued to explore the cave in search of a few more ginseng fruits.

However, because the area of the cave was too vast, Li Ang searched for a day and a night, and only found seven or eight ginseng fruits, each of which was enough to weigh five or six hundred catties, which was a huge amount.

"It seems...... I can only wait until later. ”

Leon rubbed his sore shoulders and prepared to leave the cave.

At this moment, the mutation protruded.

Inside the cave, a violent whirlwind suddenly blew, rolling up a large pile of sand and dust, obscuring the moonlight, blurring the vision, and faintly seemed to have something flying by.

Li Ang was shocked, and when he looked at it, there were black centipedes the thickness of thumbs lying on the rock wall at the top of the cave, twisting their bodies, opening their teeth and dancing claws, and pounced on Li Ang like a tide!

The centipede's head is grayish-brown, its back is oval, and there are many small transparent holes in which the eyeballs drip.

They moved quickly, spit letters quickly, and in the blink of an eye they climbed up Leon's legs and up their trouser legs.

"Ahh

Li Ang was so frightened that he struggled desperately, but he couldn't get rid of it at all, which triggered an even more frantic attack by the centipede.

He felt a burning pain in his right arm, and when he looked down, he saw that the wound on his left wrist had festered and suppurated, and dark green mucus was leaking.

"Mom, I was really bitten!"

Li Ang screamed, quickly pulled out the machete on his waist, and swung the centipede.

The machete sharpens the iron like clay, instantly severing the centipede's neck and cutting it into several pieces.

Li Ang didn't care about disposing of the centipede corpse, so he hurried away, walked through the cave, and ran to the river beach.

"Whew~"

He breathed a long sigh of relief and wiped the cold sweat from his forehead, rejoicing in his heart.

"If it weren't for the protection of the defensive force field provided by the system, I would have been cold by now."

Li Ang secretly mused: "Fortunately, I noticed this ditch before, and I went around half a circle along the river, and I didn't enter the cave, so I was saved from the poison of centipedes." ”

In that situation just now, anyone who fell into the cave would be more than lucky.

Li Ang stood on the shore and gasped for a moment, and suddenly found that the bucket of "ginseng juice" he had just thrown away had disappeared without a trace at this time, and even the bowls and basins were gone.

He was stunned for a moment, and then remembered that the cave was full of miasma, and the sap of the ginseng fruit tree quickly evaporated, leaving only a puddle of black stains, proving that it really existed before.

"Strange, how did it disappear......"

Li Ang frowned and thought, and suddenly a flash of inspiration.

He took out a flashlight he bought from the proprietress and shone it on the nearby valley.

With the help of the light, he could clearly see that there were many black markings on the surrounding hillside, like the spots of some kind of plant or insect.

The muscles in the corners of Leon's eyes twitched twice, and a strange thought popped up in his mind-

"Those spider cubs, don't they also have such markings......

Leon gathered his thoughts and decided to come back to the cave later.

This time, the target is still the eggs and calves of piranhas.

But for the sake of prudence, he first groped the surrounding mountain walls to make sure that there was no other exit, and then cautiously walked to the edge of the cave and threw the barrel into it.

Crash!

The barrel rolled into the hole, splashing dirt and quickly calming down, apparently all the piranhas inside were dead.

“……”

Leon hesitated, and slowly lifted the bucket with the bottom facing up, revealing a bucket full of viscous and foul-smelling blood and feces.

“……”

Leon sighed silently, moved the barrel aside, and dragged the corpse away from the ground.

Although this skeleton has been badly decayed, judging from the outline, it should be a woman, about twenty years old, with a beautiful appearance, a tranquil temperament, and quite charming.

Leon pondered for a moment, gently wiping the woman's body with his sleeve to make sure her shell had not been devoured by a piranha.

"Forget it, you won't survive anyway, so let me do something good for you......"

Leon muttered to himself, filled his mineral water bottle with water, and irrigated her.

Then he lifted his eyes and looked intently into the depths of the valley.

"The scale of this cave is very large, if there is a treasure in it, there is definitely more than this piranha, maybe there are even more powerful monsters......"

Leon frowned, did not dare to go deeper, turned out of the valley, found a hidden corner nearby, and began to dig the rock wall next to the cave entrance.

"Click, click, click......"

A crack opened in the rock wall, and Leon grabbed the shovel and dug hard, quickly pulling out a palm-sized piece of metal wreckage.

"This ...... Could it be a meteorite fragment? ”

Leon picked up the shovel and weighed it, and found that the shovel was very heavy.

This piece of broken metal, the surface is uneven, as if it was cast from some kind of metal, the material is neither gold nor silver, the whole body is pitch black, exuding a strange and cold atmosphere, as if it can freeze the soul.

"This thing shouldn't be simple."

Leon rubbed the wreckage of black iron, and suddenly, his face changed slightly, and he found that there was a thick layer of rust on the edge of the wreckage, as if it was covered with a thin film of oil, wrapping the wreckage tightly and keeping it in its original state.

"Is this the thing...... Causes ginseng fruit trees to wilt? ”

Leon looked closely and noticed that the rust on the edge of the oil film was slightly different from other areas.

It stands to reason that ginseng fruit trees grow in a special environment, with hard bark like steel and dense branches, which are easily melted by sun exposure, so it is impossible to cover the oil film for a long time.

Unless......

"Unless, the texture of this piece of black iron is very sparse, stronger than ordinary copper and iron, and even stronger than steel, so that it can withstand sun exposure?"

The more Leon looked at it, the more he thought it was possible, and he tried to tap the edge of the wreckage with his fingers, making a metallic crunch, and couldn't help but secretly stagger.

"Is it a metal meteorite?"

Li Ang guessed that this kind of black iron has a special texture and is hard to find, and if you can get a batch back, it will definitely be worth a lot of money!

"Huh? There's a hole here! ”

Suddenly, Leon noticed that there was a stone door in the dark cave with exquisite totems carved on it.

"Could it be that the secret of this giant cave is hidden behind the stone gate?"

He put down his shovel and cautiously poked his head out to look at the stone door.

Outside the stone gate was a not-so-spacious space, with several faint blue candlesticks hanging on the walls.

Li Ang held his breath, quietly approached the door, turned on the fluorescent light of his mobile phone, and observed carefully.

The stone gate is three meters high, and due to the erosion of history, the surface is rusty, but it can still be clearly distinguished, which is the traces left by human civilization.

Li Ang's heartbeat accelerated inexplicably, and he reached out to touch the stone gate, feeling the cold and hard surface of the stone gate.

This stone gate is not just an ordinary stone door, it contains extremely strong power fluctuations, as if it was left by a strong warrior.

Li Ang's eyes narrowed, and a strong vigilance floated in his heart.
