Xu Dong fell into the hole, only feeling the sound of the wind whirring in his ears, and he couldn't see anything in the dark. It's just that the hole under this hole seems to be getting more and more spacious, and it is like a parachute jump in free fall at least more than three hundred meters deep, Xu Dong's eyes suddenly lit up, and an underground world completely different from Xu Dong's imagination appeared in his eyes!

Xu Dong was at least nearly 200 meters away from the ground at this time, and he could still see the mountains and rivers in the distance in mid-air. It's just that the peaks of this underground world are directly supported by the rock top wall above, like pillars supporting the sky. And the stone wall at the top doesn't know what substance it contains, but it can actually emit a faint blue light. So the underground world is not dark, although it is not as bright as on the ground, but you can still see things clearly from the light emitted by the top wall.

When there was still a height of about twenty or thirty meters from the ground, Xu Dong took a deep breath, slowed down the sharp decline in speed with a light skill, and then roared and struck a palm with all his strength downward! The vigorous internal force surged out, and Xu Dong easily landed on the ground with the anti-shock force of this palm.

Down-to-earth, Xu Dong looked up at the top wall at a height of two hundred meters and calculated the distance. Boy! The thickness of the top wall was more than 300 meters, and then it fell close to 200 meters. In other words, jumping off the ground and falling a mile to the ground!

Looking around, the terrain is very flat. There are many trees that are not very tall and have purple leaves, and there are gray fruits the size of bowls hanging from them. The ground is also covered with a thick layer of purple bryophytes. In the distance, there were some long-haired, horn-like animals that looked like hippos and were leisurely gnawing on the moss on the ground. But I didn't see Zhou Yiqing's figure.

Xu Dong was about to look for Zhou Yiqing, but he only heard a strong wind sound overhead. Xu Dong instantly rolled back and jumped out more than ten meters! "Bang", the place where he was standing was smashed by Xu Song, who jumped down from above! Xu Song stood in the pit, his Dark Fear armor was too heavy, and he smashed the hard granite ground into a cobweb-like fractured area.

"! Fortunately, Lao Tzu hid quickly! Otherwise, you slut will be smashed into pizza! Xu Dong pointed at Xu Song's nose and scolded.

Before he finished scolding, he heard a scream from above that he fell from a height. Xu Dong looked up and saw that Ya Bai's hands and feet were shaking and falling from above!

"it!" Xu Dong was startled, his figure instantly turned into an afterimage, jumped more than ten meters, and caught the white teeth falling from above at the last moment!

"Didn't Lao Tzu let you go back with Nake? What are you jumping off for? Xu Dong said depressedly.

"The hosts! The white teeth don't worry about you! Yabai follows the master! Yabai shouted.

"Hey~ You're a weak goblin, what's the use of coming along?" Xu Dong complained in his mouth, but gently put down the white of his teeth.

"Doesn't this look like a dungeon? Zhou Yiqing, what about that kid? Xu Song asked.

"Here, here! I am here! Zhou Yiqing got out of a small forest dozens of meters away, holding two gray fruits in her hands, and shouted to Xu Dong: "Come and take a look!" This fruit tastes good! ”

"! Don't just eat indiscriminately! Xu Dong was shocked, rushed to Zhou Yiqing in a few steps, and without saying a word, took out a pearl and pinched Zhou Yiqing's neck and stuffed it into his mouth!

"Shark pearls, which are said to detoxify, just in case." Xu Dong said.

"Ahh Don't stuff dead fish beads in my mouth! This fruit is not poisonous, and it is not a fruit! What a good thing! Zhou Yiqing spit out the pearl and said.

"Oh?" Xu Dong picked up a fruit and looked at it, a fruit the size of a small watermelon, and when he broke it, it was full of small white and crystal clear fruits like pomegranates.

"Wow, is this the legendary fragrant fruit rice? I heard that there are some areas of the underground world that grow a kind of fragrant rice tree, and the fruit that produces is fragrant fruit rice! This is a very good food, and eating it regularly can also improve physical fitness, health and longevity. Yabai said.

Xu Dong was overjoyed when he heard this, and looked around, and there were patches of this purple leaf forest. The tree is full of such fruit.

Quickly broke a few grains and stuffed them into my mouth, and after chewing, my mouth was full of fragrant, glutinous and soft, and there was a hint of sweetness, which was very delicious. I'm afraid that even the best rice is not so delicious.

"Hahahaha! It's a no-brainer! It's full of fragrant rice trees! I can't finish the food in the pearl collar now! Xu Dong laughed wildly.

"Hey, look, there's a lot of silly long-haired cows and horses. You can tell that the meat is delicious at first glance! Zhou Yiqing said with a smile.

"Let's go, let's take a look at the terrain separately, if there is no one here, we will occupy this underground world! Yabai waited in place and came back an hour later to gather here. Xu Dong said as he sacrificed the Yin Wind Sword, and the sword flew towards the east. Xu Song and Zhou Yiqing also carried light gongs and galloped away in the north and south directions respectively.

As a result, Xu Dong flew eastward for more than thirty miles, and saw a tall stone wall. After flying against the stone wall for a while, making sure that this was the end, Xu Dong had no choice but to fly back to the same place and wait for the results of Xu Song and Zhou Yiqing's exploration with Yabai.

Half an hour later, Xu Song and Zhou Yiqing both returned. It's barely an hour yet.

"Big brother, it doesn't seem to be as big as you think. I ran south for more than sixty miles, and I came to the end. However, there are many fragrant rice groves along the way. There are also a lot of cows that look like hippos. No carnivores or other threats were found. Xu Song said.

"I only ran more than 40 miles north to the end, and the situation was basically the same as that of Ah Song, and I found a herbivore like a pig. Nothing else was found. Zhou Yiqing said.

Xu Dong said: "There is no road for thirty miles to the east, so the distance between the north and the south is more than a hundred miles." But the west side hasn't been explored yet, so let's go west and have a look. There are many streams flowing from the rock walls to the west, and it is hoped that there will be other discoveries. ”

So the three of them all performed light skills and ran westward, Xu Song put the white tooth on his shoulder and ran away, fortunately, the goblin weighed more than forty pounds, which was almost negligible compared to Xu Song's armor.

Everyone ran all the way to the west for more than 300 miles without seeing the end, this underground world is like a long barrel, very narrow from north to south, but long from east to west.

"Look, there are bones!" Zhou Yiqing's eyes were sharp, and he found some bones exposed in the soil on the ground.

Everyone stopped to observe, and the bones were almost rotten because they were so old. Half-buried in the shallow earth, with only a few skulls that are still intact, this skull resembles a human, but with two horns like sheep's horns.

"What's that? Orcs? Xu Dongdao.

"No, master, this is the Quinn! Quinns are generally tall and have two horns. Yabai said.

"Look, there's half a bronze shield here! Hey, this skull is a human skull! Zhou Yiqing pulled out a broken shield from the dirt and said.

"It seems that the legend is true, these bones are supposed to be left over from the battle between the Quinns and the undead two thousand years ago. These human skulls are supposed to belong to the undead. Xu Dong pondered.

"Then we should be careful, I don't know if there are any undead who have survived to this day." Xu Song said solemnly.

"Probably not, it's been more than 2,000 years. And the undead hate living creatures, there are many animals here, and if there were undead beings, they would have killed all the animals here. Yabai said.

Xu Dong nodded and said, "Anyway, it's okay to be careful, slow down and search forward."

The four of them cautiously advanced for another twenty miles, and finally saw the towering stone wall at the end of the underground world in the distance, and next to the stone wall was a large-scale castle, the whole castle was made of huge stones, and it had not been greatly damaged after thousands of years.

Everyone ran to the castle excitedly, and Xu Dong seemed to see many figures flickering in the castle less than two miles away from the castle.

"Stop! Is that...... it! That's the undead! Xu Dong shouted.

Everyone took a closer look, and sure enough, the castle was crowded with a dense army of skeletons! There are tens of thousands of them!

"Not good! They see us! Zhou Yiqing shouted.

The army of the undead in the castle had a commotion because of Xu Dong's arrival, but they did not go out of the city to chase and kill.

"Hmm, why don't they chase them out?" Xu Dong wondered.

"They may not be able to leave the confines of the castle. Seem...... Looks like they're guarding something! Xu Song said.

"Guarding something! Treasure! The treasure of the Quinns! Xu Dong's eyes flashed with gold, and he shouted.

"Look at those skeletons, they look miserable!" Zhou Yiqing said.

When everyone looked at it, they saw that many of those skeleton soldiers were missing arms and legs, and the armor they were wearing was rotten. There were also two skeleton soldiers who were hit a few times by their companions because of the riot just now, and they broke up directly!

"Haha! Loose bones! Sure enough, two thousand years are unbearable, even the undead can't bear it! These undead are vulnerable, follow me! Take back the treasure that belongs to Lao Tzu! Xu Dong laughed loudly and rushed to the castle first.

"! No matter how weak these undead are, there are tens of thousands of troops! Xu Song shouted urgently. But when he saw Xu Dong rushing forward like a madman, he had no choice but to follow with Zhou Yiqing and launch a charge! The goblin tooth white little arms and legs didn't dare to rush, but only shouted in place to cheer for Xu Dong and them.

So there was an eerie scene, with three humans charging towards a castle guarded by an army of tens of thousands of undead. At the front was a priest dressed in the bishop's robes......

"It's all for Lao Tzu to die!" Xu Dong crashed headlong into the skeleton army, broken bones flew everywhere, and more than a dozen skeleton soldiers were directly knocked apart.

"Hahaha! It's really vulnerable! Streamer Twin Sword Dance! Spin Kill Sword! Xu Dong laughed, and two flying swords flew out of the sword box behind him, rotating around Xu Dong and killing all the skeleton soldiers who approached.

There was a loud bang, Xu Song also rushed into the castle, and beat several skeleton soldiers into slag with an armor-breaking stick in his hand, and pushed forward with the stick regardless of the way, and all the skeleton soldiers in front of him became powder! And the rusty sword in the skeleton soldier's hand slashed at Xu Song's heavy armor, only to pop out a series of sparks.

Zhou Yiqing followed behind Xu Song, holding a shield in one hand to protect herself, a long sword in her right hand and a small skeleton in the other, and the speed of the shot was extremely fast, leaving only a broken bone behind him.

"Kill! Victory will be ours in the end! The treasures are all Lao Tzu's! Xu Dong yelled excitedly, leading Xu Song and Zhou Yiqing all the way to the inside of the castle!
