Three days passed quickly, and Lu Yin finally left White Mountain with Long Xi. Their mount was the Emissary level beast that Elder Long Kui had called Hou.
The Emissary level beast was quite fast, and it flew from a high altitude. In the blink of an eye, White Mountain gradually disappeared.
According to Long Xi, their destination was the Mortal Realm to pay respects to the Ancestral Mang.
Every main bloodline member had to pay respects to the Ancestral Mang at their wedding.
Lu Yin was both nervous and excited at the thought of seeing the enormous Ancestral Mang that could wrap around the Mother Tree. That was a Progenitor, and it would be the first Progenitor Lu Yin had ever seen.
Mountains and rivers flashed by quickly, and the Emissary level beast's speed was far beyond what Lu Yin could see. On the Fifth Mainland, everything would avoid an Emissary level powerhouse, but in the Central Realm, there would occasionally be provocative roars.
There was no lack of Emissary level creatures here, and Lu Yin trembled when he heard them. He was afraid that they would encounter a creature with a power level of more than a million and be swallowed whole.
The Central Realm was huge, and even with Hou's speed, it would take them some time to reach the Bifrost.
An invisible layer of air on Hou's back helped Lu Yin and the others block the wind pressure caused by their speed. Lu Yin touched its back, and when he saw that Long Xi and the others weren't paying attention, he pressed harder. Its skin was very thick, and when he pressed harder, the thick scales on Hou's back began to flatten. Lu Yin immediately stopped when he saw this, afraid that he would crush the scales and be discovered.
However, his worries were unnecessary. Hou was a beast, and its defense was incomparable to a human's. Lu Yin had been able to repel Emperor Luo and injure Crimson Lord with his bare hands, but it was impossible for him to injure Hou, let alone press down on it.
Hou didn't even notice.
"The Mortal Realm is dangerous, and only the two of us can pay respects to the Ancestral Mang. No one else can protect us, so follow me closely," Long Xi said calmly as she sat in front of Lu Yin.
Lu Yin nodded. The Bifrost was getting closer and closer, and White Mountain wasn't too far from it. There was a large area further away, and the Farmer's Seed Garden was even further away.
Sometimes, Lu Yin couldn't understand how a tree could be so big that it could support a continent that was even larger than the Outerverse. He couldn't imagine how a python could wrap itself around such a huge tree. This part of the sky was overturning his common sense..
Something that defied common sense occurred. He stepped onto the rainbow.
Rainbows could also be walked on like land, and there were buildings, armies, and even rivers. The rivers were colorful, exactly the same color as the rainbows.
Is this a rainbow?
Bridge?
The Rainbow Bridge was very large. From White Mountain, one could see the width of the Rainbow Bridge. It ran through the Three Realms from top to bottom. Even if the entire White Mountain was moved over, it wouldn't be much to the Rainbow Bridge. And it was said that this place was under the control of the Shenwu Heaven.
There was a red glow beneath his feet that was as soft as sand. Lu Yin was rather surprised, but he didn't show it.
Within the rainbow, the colors flowed, and there was no need for Lu Yin to run. Each color alternated with each other, and there were seven colors: red, orange, yellow, green, blue, indigo, and violet. The red color flowed towards the lower realm while the orange color flowed towards the top realm at an extremely fast speed.
Lu Yin and Long Xi's group weren't the only ones heading towards the lower realm. There were many others who came from the Middle Realm, and most of them were exploration teams. Even they didn't dare to approach Lu Yin's group.
From the books, Lu Yin had learned that the lower realm was one of the most dangerous places in the Astral Tree Realm. In layman's terms, it was the root of the tree. It was filled with terrifying creatures that survived by destroying the mother tree. If even the mother tree could be destroyed, then the people who lived on it would be even more terrifying.
The Ancestral Mang also lived in the lower realm.
The red color flowed towards the lower realm, and Lu Yin's group was very quiet. There was no one around them, and the closest person to them was at least a few hundred thousand kilometers away.
Just as Lu Yin's group was heading towards the Mortal Realm, group after group of people stepped onto the Bifrost Bridge. They recalled Lu Yin's appearance in their minds. This person was their target for this trip.
There was no place darker than the lower realm, and the White Dragons were worshipping the Ancestral Mang, so they couldn't be protected by others. This was the best time to act.
He followed the Bifröst towards the Mortal Realm, and soon, he saw an endless underground world. This was the land of the Middle Realm, and it took a while for his vision to brighten up. The air had also changed, and it was now slightly damp. There was also a strange smell of decay in the air.
Looking into the distance, Lu Yin saw clouds beneath his feet, and even below that, he could vaguely make out the outline of a continent. That was the lower realm.
After arriving in the lower realm, the aura of the pyrolyte suddenly changed. It became incomparably terrifying, as if it was trying to intimidate something.
Long Xi asked Lu Yin, "Have you been to the lower realm before?"
Lu Yin didn't know how to answer, as he was afraid that he would be exposed.
"It's normal that you haven't been here before. There's no need to hide it."
Lu Yin coughed but didn't say anything.
"The lower realm is extremely dangerous, and there are all kinds of creatures there. The only purpose of these creatures is to destroy the roots of the Mother Tree. All living things grow and absorb nutrients, and the Mother Tree is no exception. You can see these creatures as the Mother Tree's enemies, but they are also the enemies of humanity," Long Xi said. She paused for a moment before continuing, "According to statistics, unknown creatures are born every year, and every year, members of the White Dragon Clan die in the lower realm. The Four Cardinal Scales are no exception.
"As for the exploration teams in the Middle Realm, the number of deaths is incalculable. Some of these people are hired by the Mother Tree, while others are there to make a fortune or to search for valuable things, such as natural treasures."
Lu Yin understood that since the Mother Tree absorbed nutrients, the roots of the Mother Tree in the lower realm would definitely be the place with the most nutrients. This way, it would be easier for rare treasures to be born.
Everything had two sides. The Mother Tree absorbed nutrients from the universe to survive, but the universe couldn't allow the Mother Tree to absorb them without limit. There would definitely be creatures that would destroy the Mother Tree, just like how there would always be antidotes within a hundred steps of a poisonous snake.
It was as if everything in the universe had been arranged.
"There are many regions in the lower realm, and the overall area exceeds the Middle Realm and the Top Realm. We're going to the third region where the Ancestral Mang's head is. Because of the head, there isn't much danger there. Even so, we don't have Elder Long Kui and Tian Hou to protect us, so we have to be extremely careful. Over the years, many of our clansmen have died in the third region," Long Xi explained.
If not for the fact that they needed to investigate the Frigid Immortal Sect's finger, this would be the best place to leave the White Dragon Clan.
Lu Yin stretched out a hand, and a layer of clouds streaked across his palm. It was cold.
In the distance, a strange current of air crashed over, distorting the void and bringing with it a world-shaking might. Lu Yin's expression changed slightly; what a fierce attack!
Tian Hou raised a claw and slashed down, tearing through the air as it roared into the distance. In the distance, a huge head with a long neck looked up at Tian Hou with a ferocious gaze. It opened its mouth and roared as well. Tian Hou was furious.
How dare a beast that wasn't even an Emissary provoke him? It didn't even have as many heads as he did. How presumptuous! Just as it was about to roar again to show its might, another head appeared beside it. This one was ten times larger than the previous one, and its neck was completely raised. It was almost at the same level as Lu Yin and the others, and then it roared at them.
Lu Yin felt a chill run down his spine. This was a beast that had surpassed the Emissary level, and not just any ordinary level at that. Was this the lower realm?
Tian Hou was clearly stunned for a moment, and then it cowered. Its two heads drooped as it howled.
Long Kui's mouth twitched. How embarrassing.
At this moment, another head that was even bigger and taller than the second beast that had appeared was raised high up in the air.
Long Kui was stunned. The three heads were raised high and stared at them, and a chill ran up his spine.
Lu Yin was stunned. Was this a family of three?
How was this possible?
Long Xi's expression turned ugly. They had just arrived in the lower realm, and they had already encountered more than one of these monsters.
Tian Hou immediately laid down, fully expressing what a coward was.
Fortunately, the family of three didn't attack them. The smallest one roared happily and looked very proud, but it was pushed down by the tallest one. It opened its mouth and ran away, while the other one growled anxiously. If these three beasts weren't that big and were just like pets, it would have been a very harmonious scene.
Lu Yin relaxed. He glanced at Tian Hou. He had thought that this guy was very powerful, but he was actually so cowardly that he could only bully him a little.
Long Kui coughed, "Princess, be careful. The lower realm changes every year, and sometimes even every day. Leave immediately after paying your respects to the Ancestral Mang. Don't linger, and don't try to take any strange items you see. It's easy to lose your life."
Long Xi nodded, "I know."
Lu Yin began to feel that he had been too naive. He had thought that the lower realm was the best chance to escape from the White Dragon Clan, but in a place like this, he could lose his life if he wasn't careful.
The lower realm wasn't the end of the Bifrost Bridge, so Lu Yin and the others climbed onto Tian Hou's back. Tian Hou was much more obedient now, and he didn't dare to Zhang Yang too much. He quietly led them away from the Bifrost Bridge, and his huge body slowly landed in the forest near the bridge.
Long Kui said, "Princess, this is as far as we can go. Take care."
Long Xi nodded, "Thank you, Elder." She then looked at Lu Yin, "Let's go."
Lu Yin nodded to Long Kui and followed Long Xi in a certain direction, "Do you know the way?"
"We're very familiar with the third region. Even if we haven't been here before, we've memorized the map."
"How big is the third region?" Lu Yin asked.
Long Xi muttered, "It's about the distance between Baishan Mountain and the Bifrost Bridge."
Lu Yin was speechless, as this place was too big. Even with Tian Hou's speed, it would take them several days to fly through it. It would take them at least ten days to traverse it, and that was under the assumption that they would be flying through the sky without any obstructions.
If they dared to fly in this place, they wouldn't be far from death.
Lu Yin and Long Xi headed in a certain direction while Long Kui quietly stood in place.
Half a day later, a group of people arrived. The leader was a sturdy man who carried a huge metal weapon that was ten meters tall. He led a dozen people towards the third region.
