"It's still in the cave, it's going deeper, and the cave leads to the depths of the earth, and now it should be more than 1,300 meters above the surface."

Ye Fan is a Ph.D. in the Department of Earth System Science and has a rough judgment on the depth of the cavern.

"No wonder the signal is so weak." Nighthawk suddenly realized, "If you continue to go deeper, we may lose contact, you must pay attention to safety." ”

"Yes, don't worry."

Ye Fan hung up the phone and continued to go deeper, and after more than two hours, the cave became damp, and the faint sound of running water came from the depths of the ground.

"Is it an underground river?"

Ye Fan quickened his pace and walked forward four or five hundred meters again, and an underground dark river seventy or eighty meters wide appeared in front of Ye Fan.

"So big?" Ye Fan looked at the turbulent water, and was secretly shocked in his heart, the underground dark river is generally not large, and the largest underground dark river recorded in the book is only more than ten meters wide.

According to the situation of the underground dark river, the position where Ye Fan is now standing is in a cave on the edge of the underground dark river.

"Did all those cobras flee into the underground river?" Ye Fan looked contemplative, considering whether to follow the dark river to continue the investigation.

With a strong sense of curiosity, Ye Fan finally decided to follow the dark river and move on.

Ye Fan's figure jumped, and he walked quickly along the stones on the edge of the dark river, sometimes jumping, sometimes rushing, and after almost an hour, a bright light appeared in front of Ye Fan.

"Got to the exit?"

Ye Fan accelerated forward, and after a while, he came to the position of the light source.

"It's incredible."

At this time, Ye Fan had already come to the end of the dark river, but Ye Fan never expected that the end of the dark river turned out to be a huge abyss with no depth, the bottom of the abyss was covered by clouds and mist, and the light source was actually shining upward from the bottom of the abyss.

Ye Fan didn't think too much about it, took out the multicolored stone from the storage ring and held it in his hand, and then used the Five Elements Escape Technique to escape into the rock, and quickly explored down the edge of the abyss.

Ten minutes.

half-hour

……

Two hours.

……

"Why is it so deep?"

The more Ye Fan went down, the more frightened he became, he had been walking underground for three hours, and he had not yet reached the bottom of the abyss, the edge of the abyss was still covered by clouds and mist, and the water was still rushing downward, if it weren't for the multicolored stones to replenish the vitality, the vitality in Ye Fan's body would have been exhausted.

Keep going down.

In the past three hours, the clouds and mist at the edge of the abyss gradually decreased, and after walking down for another half hour, what appeared in front of Ye Fan's eyes was the endless green mountains and green waters.

In the distance, among the green mountains, stands a huge high mountain, and there is a huge ball of light on the top of the mountain, and the light emitted by the ball of light illuminates the underground world.

If it weren't for the existence of this ball of light, Ye Fan would have thought that he had returned to the surface, if he hadn't seen it with his own eyes, Ye Fan would never have imagined that there was such a huge world deep underground.

After exclaiming, Ye Fan continued for more than an hour before he came to the bottom of the abyss and appeared in front of a huge waterfall.

The flying stream went straight down to 3,000 feet, and it was suspected that the Milky Way had fallen for nine days.

Li Bai's poems were no longer enough to describe the scene in front of him, and according to Ye Fan's calculations, he had now gone at least two hundred kilometers underground.

Ye Fan took out his mobile phone and communication watch, but there was no signal at this time, so he turned on the camera function of his mobile phone, took a photo of the waterfall, and then turned off the mobile phone and communication watch.

Ye Fan looked down at the blood-red clothes all over his body, and secretly regretted in his heart that he didn't prepare some clothes to put in the storage ring.

Ye Fan looked around, took off all the clothes on his body, came to the waterfall to take a bath, and then began to wash his clothes.

Half an hour later, Ye Fan cleaned the blood stains on his clothes, wrung out his clothes slightly, and immediately put the wet clothes on his body, after all, he was very unaccustomed to being naked.

Ye Fan walked quickly along the edge of the river, heading towards the green mountains in the distance, and a quarter of an hour later, Ye Fan entered the forest.

The trees in the forest are unusually large, and large trees surrounded by two or three people can be seen everywhere, and the ground is covered with fallen leaves.

"Rustle... Rustle..."

Ye Fan stepped on the fallen leaves.

"Woo...... Whew......"

Suddenly a wolf howl rang out in the forest.

Ye Fan immediately cast the Five Elements Escape Technique into the ground and walked in the direction of the wolf's howl......

In the forest, a group of giant cyan wolves, as strong as cattle, surrounded a middle-aged man armed with a black machete.

The middle-aged man was dressed in animal skins, with a muscular build, yellow skin, black eyes, long hair that reached his shoulders, and a long bow and arrow basket on his back.

There were several corpses of cyan giant wolves lying on the ground around the middle-aged man, and each cyan giant wolf corpse had a huge wound half a meter long on its belly.

"Drink!"

The middle-aged man let out a loud shout, his legs bent, his body leaned back, and the black machete in his hand slashed at a giant cyan wolf that pounced on him.

"Poof!"

The cyan giant wolf had a huge wound in his belly, and when he landed, his limbs went limp, and he lay on the ground and convulsed.

"Whew......"

There was a wolf howl from among the wolves, and a huge silver wolf came out of the wolf pack, revealing its sharp fangs at the middle-aged man.

When the middle-aged man saw the silver giant wolf, a trace of horror flashed in his eyes, and without the slightest hesitation, he immediately turned around and rushed backwards, rushing towards a cyan giant wolf not far away.

Sou!

A silver light flashed in the field, shooting straight towards the middle-aged man.

"Bang!"

The longbow and arrow basket behind the middle-aged man instantly shattered, and the middle-aged man's body was thrown forward, leaping past the cyan giant wolf and crashing into the trunk of a large tree.

"Boom!"

A bang sounded, and the branches and leaves of the big tree that were hit trembled wildly, and after the middle-aged man hit the big tree, his body fell to the ground, his back was soaked with blood, and the black machete fell to the side, and his body struggled to get up from the ground.

"Poof!"

The middle-aged man suddenly spurted out a mouthful of blood, his hands supported on the ground became weak, and he fell to the ground and fainted.

The silver giant wolf came to the middle-aged man's body, raised his sharp claws, and swung at the middle-aged man's head.

Just as the claws were about to hit the middle-aged man's head, Ye Fan suddenly drilled out of the ground, and the Emperor Sky Sword in his hand stabbed at the head of the silver giant wolf.

"Boom!"

The head of the silver giant wolf suddenly exploded, and it instantly became a headless wolf corpse.

"Whew... Whew..."

The sudden change caused the cyan giant wolf to let out a howl of fear, and its body slowly fell backwards, and then turned around and fled in all directions in the forest.

Ye Fan glanced at the cyan giant wolf that had fled, turned around and came to the middle-aged man's side, raised his hand to his neck, and checked the middle-aged man's vital signs.

"Alive."

Ye Fan looked around, his eyes suddenly lit up, and his figure flashed to the bushes not far away, pulled out a green vegetation, and returned to the middle-aged man.

Ye Fan tore open the animal skin worn by the middle-aged man, revealing his bloody back, then quickly picked off the leaves of the green vegetation, rubbed his hands together, and then applied the rubbed leaves to the wound on the middle-aged man's back.

"Good luck."

Ye Fan looked at the remaining green liquid in his palm, and the green vegetation he pulled out was a common hemostatic herb Panax notoginseng.

Half an hour later, the middle-aged man woke up slowly, sat up with his hands on the ground, and when he found Ye Fan on the side, a trace of confusion flashed in his eyes.

Suits, shirts, trousers, leather shoes.

He had never seen such a shape in his life.

"Gollum Boom ......"

The middle-aged man looked at Ye Fan and opened his mouth to say words that Ye Fan didn't understand at all.

"It's over, the language barrier." Ye Fan touched his forehead with one hand, revealing a helpless look.

Helplessly, Ye Fan raised his finger and pointed to his ears, pointed to the silver giant wolf corpse on the side, and pointed to the middle-aged man's back.

The middle-aged man suddenly realized.

Deaf.

It was he who killed the silver wolf and saved him.

This is what the middle-aged man thinks at this time.

The middle-aged man slowly stood up, bowed to Ye Fan, and then pointed to the corpses of the silver giant wolf and the cyan giant wolf.

"I guess I'm asking if I want these corpses?"

Ye Fan immediately shook his head.

I don't know if the middle-aged man understood what Ye Fan meant, the middle-aged man put all the corpses of the cyan giant wolf and the corpse of the silver giant wolf together, and then bowed to Ye Fan again, and then turned his head to leave.

"Fainted."

Ye Fan showed a helpless look, watched the middle-aged man leave, put the giant wolf's corpse into the storage ring, and then his figure flashed into the ground, and fled in the direction of the middle-aged man's departure.

Follow all the way.

Ye Fan followed the middle-aged man after four or five hours of climbing mountains and mountains and came to a valley.

I saw a village in the valley, the village was full of wooden houses, and the village was surrounded by a rock wall more than ten meters high, enclosing the whole village.

The valley was filled with smoke, and two men in animal skins were on duty on the walls, and the sound of children playing could be heard from within the walls.

When the man on the wall saw the middle-aged man returning, he immediately put down a wooden ladder more than ten meters long, and the middle-aged man climbed up the fence along the wooden ladder.

Ye Fan passed through the wall from the ground and entered the village, only to see more than thirty men and women wearing animal skins gathered in the village, all surrounding the middle-aged man who had just returned, with a concern, sorrow, and sad expression.

These villagers all have one characteristic, that is, they are skinny.

The middle-aged man said words that Ye Fan couldn't understand, communicating with the people in the village, and after a while, more than thirty men and women, including children, gradually dispersed and left, but when they left, they all looked lost.

"Alas......"

The middle-aged man sighed under his breath and staggered into a wooden house.

Although Ye Fan couldn't understand their words, Ye Fan could see that the loss of the people in the village was because of food, and the middle-aged man went out hunting, and when he came back, he didn't bring anything back.

Ye Fan, who knew the general situation, walked around the village several times and found that there was no food in some houses in the village.

"Good people do it to the end."

Ye Fan came to the center of the village, looked around, and after finding that there was no one, he immediately drilled out of the ground, took out all the giant wolf corpses in the storage ring, and then picked up a small stone and threw it to the wooden house where the middle-aged man was.

After Ye Fan threw out the small stone, he immediately cast the Five Elements Escape Technique into the ground, left the village directly, and moved forward in the direction he came.
