"The book says that the Tianhe, the weak water, and the Lethe River are actually the same river. It's just that their flow directions are different, and they exist in three different levels: heaven, earth, and underworld, so that everyone ignores this, and even uses them as boundary rivers to divide the regions of the Six Realms. Isn't it interesting? Divide and divide, and everyone ends up in the same watershed. ”

Holding a dog's tail grass, Ye Yao walked forward while turning back to chat with Xue Li.

"Oh, yes. ”

Xue Li was obviously not interested, and his heart was still hanging on the "alien feather" that could explode at any time.

At this time, Aze, who had not spoken for a long time, suddenly opened his mouth, "Tianhe Starfall, Weak Water Descending, and Lethe River Interception, these three rivers finally met at a point and merged into Taixu together." Although they have the same destination, the areas they flow through, the scenery on both sides of the river, and everything they have carried and nourished are all different. There is no problem with dividing the Six Realms. What's more, this is a covenant - a law set by the Groundbreaker. ”

"Oh, you seem to have your own opinions on the laws of heaven and earth?!" Ye Yao's eyes lit up.

Aze shrugged, "I can't talk about opinions, just think about it occasionally when I read a book." ”

Accustomed to Xueli's carelessness, it is rare to catch a book friend who can discuss a thing or two, Ye Yao hurriedly continued: "I have always had a question about the 'Battle of the Apocalypse'. ”

"How did the Demon King ambush him?" Aze asked.

"Well, that's a problem. Ye Yao thought about it and said, "But there is another question that makes me even more confused. That is, in addition to the undead, what else is important in the underworld, which is worth the risk of the Celestial Clan in the 'Battle of the Apocalypse', sending all the eight gods to suppress the Netherworld Mutation, and only using 100,000 Heavenly Soldiers to fight against the million demon alliance, almost defeated, and fell into a catastrophe. ”

Aze was stunned, and his face changed in an instant.

"You know?!" Ye Yao smiled.

"Isn't this obvious!" Aze frowned, and said sullenly, "The Netherworld holds 30 million undead. Once they escape from the underworld, they will turn into fierce spirits and bring havoc to the world. ”

When a mortal dies and the undead wade through Lethe, they will be stripped of their spiritual consciousness and then reckoned with merit through judgment. Those who do good enough to atone for their sins can be reincarnated immediately, while those who are not enough to redeem them will be imprisoned in the Netherworld and punished until their sins are fully paid.

If it is not for the undead who leave the underworld through reincarnation, they will turn into fierce spirits.

Fierce spirits have no spiritual sense, and their bloodthirsty thirst is uncontrollable.

30 million fierce spirits are indeed enough to destroy the human race!

"Would you rather perish yourself than protect the human race, is the Celestial Clan so noble?" Ye Yao asked.

Aze shook his head, looked at her and said, "It's not noble, it's the responsibility of the ruler." Human beings worship and worship God, and God cannot abandon them at the most critical moment. This is morality, and it is also ...... Covenant. ”

"That doesn't convince me!"

Ye Yao raised her eyebrows slightly, and said with a smile: "Back then, if the Eight Great Divine Clans had gone to the Nine Heavens in time to support, it would have been impossible for the Great War to drag on for so long, and there would not have been so many living beings dying in battle. No matter how it is calculated, for the Celestial Clan, the practice at that time was not cost-effective. ”

"And what do you think?" asked Aze rhetorically.

"I guess......" Ye Yao lowered her voice and said mysteriously, "The Heavenly Clan may not be the master of the Six Realms. Abandoning the Heavenly Realm and preserving the Netherworld first is a decision made by the true Ruler. ”

As soon as these words came out, even Xue Li stopped and looked at her in surprise.

"What...... What ......" Aze was speechless in surprise.

What a word!

What weird speculation?

Is she crazy?!

......

"Hahahaha-"

Ye Yao and Xue Li suddenly twisted into a ball, and let out bursts of wild laughter.

"Ah...... Aze, haha......"

Ye Yao smiled and bent over, patted him on the shoulder and said, "It's funny! When I was studying, my first thought turned out to be like this!"

"Hahaha-"

Xue Li couldn't breathe when she laughed, and said triumphantly: "This is the funniest joke she said! I've been living this joke since I was a kid!"

Aze: "......"

When mortals die, there will be ghosts who lead the way into the netherworld.

If the living want to go to the underworld, the road is far.

When they are in the mortal world, they must first wade into the weak water to reach the demon world, then pass through half of the demon world, reach the barrier "Qu Marsh" between it and the demon world, pass through the "cloud hole" in the swamp to reach the demon world, and then jump over half of the demon world to reach the Wanzhang Demon Abyss at its end, and finally reach the bottom of the abyss through the trestle bridge, and then cross the Lethe River along the connecting pontoon bridge to reach the merit post on the opposite bank.

Speaking of which, Ye Yao and Xue Li have also walked this road many times.

Fortunately, Linxian Town is located in Jizhou, adjacent to Yongzhou, where the weak water is located. The three of them traveled all night, and finally reached the bank of the weak water river on the third day. They all have excellent water properties, and they can dive to the bottom of the weak water river without much effort, and follow the whirlpool at the bottom of the river to the entrance of the demon world - the only oasis in the sand sea.

Wading through weak water in depth is the territory of the demon world.

There was no need to worry about disturbing the human race, Xueli immediately turned into a true god - a spirit beast with a foot eight feet high, a snow-white body, blue eyes and purple pupils, and fangs. Carrying the two of them at lightning speed, through the sea of thousands of miles of sand.

When we arrived at "Kogunuma", it was only noon.

"Qunuma" is under the jurisdiction of the demon clan and is the main road to the demon world. As long as you pay enough customs clearance fees, you can even have a single "cloud cave", and arrange the supreme service of the demon maid throughout the process.

The two realms of demons and demons have always had a harmonious relationship, and the people of the two clans communicate with each other and come and go frequently. Not far from the "cloud cave", you can see large and small magic markets.

The market is full of vendors from all walks of life, and regardless of the identity of the visitor, as long as there is value in the goods, they can exchange them for what they want.

Although Aze didn't register with the old man of the Stygian River, and he didn't need the "Phantom Flower" at all, Xueli, who thought that the smell of "Nine Spice Lotus" was too heavy, still used it to exchange a pair of small and cute purple "ringbells" with a demon lady in a small market.

There is a pair of demon Gu in the bell, as long as the two bells are in the same realm, when one of them is shaken, the other can make the same bell.

Time was of the essence and they were not allowed to wander around.

Reluctantly leaving the market, Xue Li exerted all his strength to eat, and when he arrived all the way to the Demon Abyss, it was almost evening, and the dusk golden crow was almost sticking to the water surface of Lethe.

The abyss was flat, with a rope hanging from the edge, and as you pulled it down, there was a wooden platform at the end, and below that was the trestle bridge, which zigzagged along the cliff wall, and the other end disappeared into the thick fog beneath the abyss.

Looking at the rope that looked rotten and seemed to break if he pulled it, Aze turned around and said, "You guys wait here, I'll go down by myself." ”

"How's that going to work—"

"How's that going to work!"

Ye Yao and Xue Liqi shouted in unison.
