I vaguely remember that it was a sunny day, and Takeya and the god of death Komachi, whom he had just met, were happily rowing on the Santu River, and then, Takeshi threw something that seemed to be very important into the Santu River.

"So why is this thing in your hands?"

After turning over and over to determine that this spoon was indeed the one that was thrown into the river by himself, Wu also said that he couldn't figure it out at all:

"Could it be that you went to the Santu River and fished it out? But I heard that the river didn't seem to be swimmable. ”

"If you want to leave a mark here, I will definitely not be stingy to help you again."

Chang'e looked at Wu Ye angrily and said:

"Do you think I'll be so idle, running to the ground just to catch the Santu River? It's worth a lot of money, but do you think I'm that boring? ”

"And how did you get your hands on this thing?"

"Of course I picked it up by floating down the river."

“...... Sorry, I didn't understand you saying it again? ”

"Really, that, see?"

Chang'e pointed to the starry sky above their heads, and Wu also looked in the direction she pointed, except for the stars or stars, she didn't see anything special:

"You said that you picked it up by floating down the river, so why are you pointing me to the stars?"

"Don't you see such a long galaxy?"

"Hey, wait, is this the river you're talking about?"

Wu Ye looked up at the starry sky, and then looked down at Chang'e, and he was not calm in an instant:

"I mean, your setting is too unin accordance with the Basic Law, right?"

"You're too ignorant, aren't you?"

Chang'e glanced at Wu Ye with disdain, and then explained:

"Originally, the Santu River was not called the Santu River, it had another name a long time ago, when hell was not established and the gods completely ruled the earth, and the name of that river was 'Heavenly River'."

"Tianhe?"

"Yes, to put it simply, it is a river that can lead all the way to the sky, and the star river you see above your head is the legendary heavenly river, that is, the source of the Santu River."

"Wait, it seems that there is no scientific basis for this setting?"

"Science?"

Chang'e looked at Wu Ye in surprise, and said lightly:

"How many people do you know have existence that can be explained by science?"

Wu Ye was stunned when he heard this, and smiled awkwardly:

“..... Well, when I didn't say, you continue. ”

"Do you know why you can't swim in the Santu River?"

"Isn't it because it's going to sink directly? I heard the Grim Reaper over there say that below the Santu River is the deepest part of hell. ”

"That's right, but in fact, there is no difference between the original Santu River and ordinary river water, and there is a reason why it has become the river of the dead like it is now."

Chang'e stretched out her hand to the starry sky, and in a trance, Wu Ye actually saw a strange scene, only to see that the starry sky really turned into a river and began to ripple:

"The Tianhe River directly connects the ground and the lunar surface, and if it is not stopped, then anyone can come to the lunar surface through it, which is the most critical reason why the Tianhe River has become the current Santu River."

"You don't like people from the earth coming to the moon?"

As soon as Takeya's words came out, he felt that he was asking a nonsense, the people of the moon are a bunch of clean-minded monsters who hate filth, and the ground seems to them to be a place similar to the place of exile, how can they like the people there to come to their city.

"I can't say that."

Unexpectedly, Chang'e did not give an affirmative answer as Wu Ye thought:

"During the time of the gods, although there were occasionally gods who did not know the so-called gods, the moon capital could not be said to be unwelcome, after all, even if it was a god who lived in a filthy land, it was still a god."

"Then why did you change the Tianhe River to the Santu River later?"

"Because the gods have fallen."

Chang'e shrugged her shoulders, her tone was indifferent to eating and drinking, and she didn't seem to have the consciousness that she was one of the gods:

"The people of the moon can allow the gods to come to the moon capital, but they will never allow humans or youkai to come up."

"So Tianhe was sealed?"

"That's not called being blocked, it's being 'blocked'."

Then, Chang'e explained to Wu Ye in lengthy and complicated words for a while before he understood what this "blocking" meant.

To put it simply, the Santu River is restricted, and dead objects can flow all the way to the surface of the moon through the river, but if it is a living thing, it will sink directly to the bottom of the Santu River.

The Celestial River was born a little earlier than Hell, so it wasn't Hell that created a river to transport the dead, but the blocked river that attracted Enma and the Grim Reaper.

Both the other side and Hell were built on the edge of the Santu River, and since the Moon People blocked the Heavenly River, the section of the Heavenly River on the ground has been completely handed over to Hell for management.

As a river that traverses the old and new hells, Wu Ye really didn't expect that this could be related to the people of the moon.

"Okay, we seem to be on the wrong side."

After explaining the relationship between Tianhe and Santuhe, Chang'e's gaze returned to the spoon that had just been exchanged into Wu Ye's hand, and said meaningfully:

"This was originally yours, and now it can be regarded as the return of the object."

"But what's the use of this thing?"

Wu Ye naturally understood Chang'e's words as politeness, but he cared more about reality than these indifferent things:

"Last time, I remember that this thing suddenly burst into flames and scared me, so I accidentally threw it into the Santu River."

Wu Ye looked at the small spoon lying quietly in his palm:

"This can't be a lighter, right?"

“...... It's good to have a lot of imagination because it allows me to punch you without any psychological pressure. ”

Glancing at Wu Ye, Chang'e felt an unprecedented tiredness at this moment, but she was still a good person to the end, and seriously explained the mystery for Wu Ye:

"The one you are holding is not something that has meaning individually, it needs to be gathered in sufficient numbers to play a collective role."

Taking the spoon from Wu Ye's hand, Chang'e looked at it carefully before continuing:

"This is just one of them, there are seven of them scattered, and there should be eight of them all if you count the final keys, and it only makes sense to collect them all."

"Hey, what you mean by that is a bit forced......?"

The corners of Wu Ye's mouth twitched slightly:

"Not to mention, I don't know where the remaining seven are, what am I going to collect this for? And it doesn't seem to be anything powerful about this, so why don't you consider giving me your blood. ”

"I'm not kidding."

Chang'e shook her head gently, looked at Wu Ye seriously and said:

"I firmly believe that everyone is born into this world with an innate mission, and from the moment you come into contact with the first one, you have no choice."

"What the hell is this?"

"No one in the world knows it anymore, but in the distant past, we used to call it that-"

Chang'e lowered her gaze, and an endless abyss seemed to be reflected in her eyes:

"The Instrument of Mortal Sin."
