The vast majority of people have heard the teacher say bitterly on the way to study: a good memory is better than a bad pen.

This sentence is the greatest truth in the current environment of the two. Luo Yang had long thought of leaving clues by recording, but unfortunately they couldn't even turn over a bad pen.

The woman didn't dare to say anything, so she could only watch Luo Yang's frowning and painful facial expression. This kind of mental torture has been experienced by everyone to a greater or lesser extent, so the woman understands him very well.

She learned to sit cross-legged across from Luo Yang.

"I think you're best at thinking about ideas that other people can't think of, not memorizing, so if possible, you might as well try to start with that."

Seeing Luo Yang slowly open her eyes, the woman said the words in her heart.

Luo Yang found that she was also sitting cross-legged and a little stunned. It's not for other reasons, it's just that I think it's a very disobedient picture to comfort herself with such patience with her character.

"Ideas?"

Luo Yang repeated her words, still shaking his head. This kind of thing didn't work with idealism, but he tried to think according to hers.

"The best way to remember a map is to have references, but what is missing here is references. I once thought about using the method of throwing gold coins to make marks, but so many numbers cannot be compiled with gold coins, we have almost hundreds of portals so far, not to mention whether there are enough gold coins, how can these gold coins convey the information of each door? ”

"I really didn't expect this, it seems that I am too talkative, and you have done your best."

Luo Yang sighed.

"I hate to admit it, but we're on the verge of failure right now. Because I can remember the limit now, if we go back the way we came, we can go back, but there really can't be anything I can do about it. ”

The woman didn't have the breakdown he imagined, and even had the heart to make a joke.

"Then we can at least go back the way we came, and maybe pick up a computer there to help you remember."

Luo Yang hadn't heard such a cold joke for a long time, and he cooperated with the woman without smiling.

"What's the use of picking up a computer? Drawing a map? It's better to pick up a pen and a notebook. ”

"You're talking about computers, I'm talking about computers. The kind that can calculate addition, subtraction, multiplication and division. ”

Luo Yang really smiled this time, it seems that women have the same ability to accept electrons, no matter how strong a woman is.

"What are you laughing at, didn't you say that you were going to calculate and compile, of course I thought of computers."

Luo Yang laughed even louder.

"Hahahaha, don't get me wrong, I'm laughing because the brain hole between us is not on the same plane. You're thinking about the old antiques of addition, subtraction, multiplication and division, which is different from what I thought, and the key is that you actually associate that thing with the word compilation, which only has a binary algorithm of zero and one......!!! ”

Luo Yang stopped laughing, he suddenly realized that he had just inadvertently said the correct answer......

"Binary! Yes! How did I forget that the core of a computer is binary!! ”

Luo Yang roared in frenzied excitement.

"See the essence through the phenomenon! What a wise saying! ”

The woman looked at the big boy speechlessly. She really didn't understand what Luo Yang thought of to be so excited.

Luo Yang took out a handful of gold coins and scattered them on the ground.

"Thanks to the game artist, there are heads and tails for the gold coins."

Luo Yang began to lay the gold coins on the ground one by one.

"The front side represents the entrance, and the back side represents the exit."

Then place the two coins face up.

"This is the way back, the front entrance, the back exit."

After placing the gold coins, Luo Yang concluded: "We don't need to remember where each intersection leads, we just need to record the entrance and exit, and when we go to the dead end and return, if we don't see the corresponding exit, we just need to find the correct gold coin to return to the next floor through the portal!" ”

"This ...... It doesn't seem to be binary! I still know a little bit about it......"

"This is a map that I wrote with zero-sum ones, and we just need to understand the meaning, and nothing else matters."

"Okay, that sounds amazing, how many gold do you have?"

Luo Yang took out the remaining gold coins and found that there were only a dozen left. It's a little embarrassing. The woman was not much better, and the two of them made up a total of twenty-eight gold coins, ten silver coins, and three copper coins.

"I learned a truth through this, you know?"

"What's the truth?"

"Bringing more money when you go out is the truth!"

Luo Yang replied with a sneer.

"All our money doesn't add up enough to the road we've already traveled, which means we have no turning back, we can only start recording from here, hoping to make it to the end."

"You mean you had to rely on your brain to forcibly record it before?"

Luo Yang shook his head.

"I mean we don't need to remember the way we went before, and if we don't get there, we've lost our ......"

After solving the memory problem, the two of them traveled at a much faster speed, but the road was longer than Luo Yang had imagined, and after running out of coins and going through a dozen or so intersections, they finally saw the iconic platform......

This time there were no chests or illusions, and a lonely portal appeared right in the middle of the platform. Luo Yang almost didn't shed tears......

This level doesn't have any combat, but it's by far the longest to date, and it's far more painful than the previous two. Without any hesitation, the two stepped into the portal.

"The exploration of the South is complete."

Luo Yang couldn't help but sigh when he looked at the last West.

"Victory is in sight!"

Then they met with the deepest despair......

They only walked for ten minutes before they reached the end of the last level, and the stone path disappeared abruptly as if it had been cut off by something, but the platform representing the end was suspended ten meters in front of them......

At first, the two of them were still trying to find clues, but after a full forty minutes, they still did not find any possible clues.

"Or if we look back, maybe we've missed something."

Luo Yang agreed to the woman's proposal, and the two walked for less than ten minutes before they found that the original intersection had also been cut off ten meters away, and the whole road was floating in the void like an island.

"There's no way back now......"

The two of them returned to their previous positions and used all the means of the previous levels, but they still did not gain anything.

They were silent......

It was only at this time that the absurd silence that had been suppressed by the two finally began to spread.
