Gu Xuanyan's words were like cold water that extinguished Zhang San's hope. At this moment, a concept that was not very rigorous but always ran through the mythological story suddenly came into Zhang San's mind.

"One day in heaven is one year on earth!"

Zhang San had no idea where this sentence came from, but as far as he could remember, he first heard it in "Journey to the West".

At first glance, the person who said this seems to be very smart. After all, in this extraordinary and insignificant world of the Dharma Ending Age, where no one can cultivate to become an immortal, even if there is a high possibility that what you said is false, you cannot refute the other party.

After all, they have no evidence to prove that this thing is true, and you also have no evidence to prove that this thing is false.

When this kind of problem arises, humans always attribute it to a paradox. Even today, when it can be explained by the theory of relativity, people just treat it as a joke.

This does not seem to be anything worth delving into, especially in the Dharma Ending Age when it is impossible to practice cultivation, and no one will delve into such issues.

But unfortunately, in the extraordinary world where Zhang San lives, this saying still exists. More importantly, judging from the Gu family's collection of books, there is someone in this world who has actually proved this.

But it’s not as exaggerated as “a year”, it’s probably about 10 days.

After all, this is not a difficult thing to prove. It is nothing more than cultivating to the realm of immortality and ascension, then taking a trip around the heaven and then coming down. In terms of logical steps, it is the same as taking an elephant out of the refrigerator.

The only difference is that when making this assumption, Zhang San always takes the speed of time in the real world as the standard for calculation, that is, "one year".

However, after hearing what Gu Xuanyan said, he realized that he still underestimated the world.

From the time the two disappeared to the time he rushed into the ancestral hall, Zhang San carefully recalled and found that the time should be about 6 minutes. After that, he successfully entered the underworld and began to fight with the deep divers.

Zhang San also admitted that in order to awaken the fighter's will (increase the number of combos), he deliberately increased his attack speed. In just a moment, he completed 150 combos and raised the fighter's will to the limit.

After that, in order not to anger Cthulhu, Zhang San deliberately slowed down the pace of the slaughter, causing only serious injuries at most.

After wasting 7 minutes like this, in order to increase the fault tolerance rate and prevent any accidents, Zhang San hurriedly left the battlefield and began to return to the direction of the ancestral hall to defend.

According to his calculations, this set of operations took exactly a quarter of an hour and there were no problems during this period.

But when Gu Xuanyan said that this was the seventh quarter of an hour they had experienced, even someone as calm as Zhang San felt his blood boiling.

Yes, if that's the case, then everything makes sense.

Compared to the heaven, the world where Zhang Sanben is located is undoubtedly the lower world, but unfortunately, due to various reasons, the status of this world is very high.

Although it is still a world governed by the heavens, it has its own set of rules and regulations in some special settings, the most basic of which is the concept of time.

Indeed, one day in heaven is one year on earth. There is nothing wrong with this basic concept circulated in the spiritual practice community. The only difference is that the "one year" mentioned here is simply the speed of time flow in the Dharma Ending World, while other super-dimensional worlds do not necessarily have to follow this rule.

Take the world where Zhang Sanben I live for example. The speed of time here is about ten times that of the heaven. If this concept is expanded and calculated, the speed of time in the underworld is actually 100 times that of the heaven.

If it were to increase three times on this basis, I'm afraid this place would enter the Dharma Ending Age.

With the support of the memory palace, Zhang San interpreted the meaning behind Gu Xuanyan's words in an instant. However, if this was true, there was really no need to rush.

"This is really unfortunate news. It looks like we have to stay here for another three quarters of an hour!"

"As expected of you, Third Brother. It seems like you have gained a lot recently!"

"It's just a simple math problem. With the support of the Gu family's collection of books, there's no reason why it can't be solved."

After clarifying the concept of time, Zhang San regained his usual composure. After all, his bowel movement lasted for a full three hours, so there was no need to make a fuss.

And to be honest, as long as Mr. Ke doesn't take action, Zhang San won't take any more deep divers seriously.

The only thing that worries him now is why the underworld, which is supposed to be on the same level as the heaven, was inexplicably downgraded? Will this inexplicable downgrade affect their return?

Due to insufficient information, even Zhang San can only infer to this extent. All in all, it is not very optimistic!

…

Compared to Zhang San who had insufficient information, Jiang, who was just doing nothing, obviously knew more, but he was hesitant at this time.

If Zhang San was just an ordinary Calamity-level cultivator, Jiang would definitely use Yaya's mouth to tell them the information he knew without hesitation, and tell them that if they wanted to leave here, they must send Cthulhu away. Only in this way would Jiang have the authority to send them away.

But it should be noted that the premise of all this is that Zhang San is just an ordinary natural disaster.

Judging from the current situation, even if Zhang San is simply using his spear and physical skills to suppress the deep diver, the fighting spirit in his body that is as vast as the ocean cannot be concealed.

Half-step to the Red Dust Immortal? No, if the "Miracle" was not occupied by another Red Dust Immortal, Zhang San would be ranked as a Red Dust Immortal just based on this unique skill.

Jiang was confident that he could hide himself in the face of a natural disaster, but he was not sure he could hide it from a Half-Step Red Dust Immortal. Even after Zhang San revealed such a high level of cultivation, the communication between Jiang and Yaya became much less.

"Jiang, are you still there? What did you mean by what you said before?"

…

"I take back what I said before. Your brother is a truly powerful man. If he had not been born at the wrong time, he would have been qualified to reach the top."

"Hahaha, I knew my brother was the best, but isn't this a good thing? Why do you still sound so sad?"

Yaya is very sensitive to changes in emotions, as can be seen from the fact that she can feel Zhang San's loneliness. Therefore, even with just simple words, she can feel Jiang's sorrow.

"Alas, even so, you still can't leave. If you don't fight in person, you will never know how powerful Cthulhu is."

Hearing that Jiang repeatedly boosted others' morale and destroyed his own prestige, Yaya became not only angry but also curious about it.

Just as she had guessed before, Jiang really knew something special. If these things were dug out, maybe her brother would be able to leave.
