Xiao Nan breathed a sigh of relief and simply sat cross-legged on the ground.

"If your brain is not good, don't use it yet. Let's eat something first. I don't understand, but I know that if you want to hurry, you can't get there. You don't put too much pressure on yourself. ”

The two of them kept walking during this time, and all their minds were on searching for clues. Nature ignores the passage of time.

After Xiao Nan reminded him, Luo Yang suddenly felt that he was already hungry in his stomach.

This gave Luo Yang a wake-up call. He hurriedly looked through the dry food brought by the two of them with Xiao Nan.

Fortunately, this time it was prepared, and the jerky and cakes would last at least two weeks. I just didn't bring much water.

Originally, the Great Wilderness World was the most lacking in water, especially in the deep mountains. As long as you replenish the water along the way, you can ensure that the drinking water problem is guaranteed. But it's clear that this is the biggest problem at the moment.

The two rummaged through the package, but there were only two hydration bags. A water bag is only a liter of water, and although a liter of water can ensure that the two of them can live for at least a week, the taste must be unpleasant.

Neither of them said anything about this matter, and after eating, they each drank a small sip of water and put away the water bag.

"I seem to have figured something out. We did go from the first level to the second level, but for some reason we ended up falling back to the first level. It can probably be understood that we will return if there is a problem with our operation. ”

"I guess I know what you mean. So what exactly is the problem? ”

Luo Yang shook his head: "We don't have much time to rest. Since you can't figure it out, you have to find the answer by constantly exploring. ”

Xiao Nan understood what he meant, so he continued to set off together.

"The clue we know so far is that you can get to the second level through the first fork. Since we can't figure out what the hell the problem is. Then we keep repeating the previous action. Until you find the fork in the road through the third floor. ”

Luo Yang said as he walked, and added: "We're going to relist before that." As he spoke, he put the gold coins on the first floor indicating the fork in the road and put them in the third column. ”

"Hmph, why don't you say that you will grow wiser by eating a trench. It's also a shame that I'm on the road with the eldest lady. I've got a lot of gold in case of emergency. ”

"Hehe, count you as acquaintances."

The two of them had fun in their suffering, and when all the preparations were done, they once again stepped into the first fork in the road. Sure enough, it didn't take long to come to the second floor.

This time, whether it was encountering the slate gate or going back directly, it was no longer strange, but carefully took notes.

Until the sixth fork in the road, the two of them walked all the way to the end, but they found the entrance to the third floor!

This new discovery shocked the spirits of the two, but Luo Yang, who had gradually realized the problem, did not rush into the fork in the third layer, but first took Xiao Nan to finish all the marks on the third floor, and then came directly to the first fork in the third layer.

"You are right, if you want to hurry, you can't get there. We are now seriously short of clues, and we should not rush forward. Instead, try to explore all the road conditions as much as possible. ”

Xiao Nan understood what he meant, and the two of them first entered the first intersection of the third layer, and sure enough, they retreated to the second layer. This time, Luo Yang did not rush back to the sixth intersection, but continued to explore directly from the seventh intersection of the second layer that they had not yet explored.

It wasn't until all the intersections on the first and second floors were recorded that Luo Yang finally began to summarize: "So far, we have got a total of 9 stone slab clues on the first and second floors. There are four pieces on the first floor and five on the second floor. ”

He paused and continued, "I'm almost certain that these numbers are the base numbers of the nine-square grid. And those forks in the road that don't show numbers need to be filled in. Usually there are only a few basic numbers when the Sudoku difficulty reaches the advanced level, but we have now obtained nine numbers just by reaching the second level, which shows that our Sudoku difficulty is not very difficult! ”

Xiao Nan nodded: "Although I don't really want to praise you, I think with your ability, you are now fully capable of cracking this nine-square Sudoku!" ”

Luo Yang nodded, and shook his head again: "Our task is to collect as much intelligence as possible, and the person who really does the question doesn't have to be me, don't forget, there are better people!" ”

Of course, Xiao Nan knew who he was talking about, and immediately retorted: "But we can't contact her now!" ”

Luo Yang suddenly touched her head and smiled: "Please! I can't get in touch in the game, and that doesn't include reality! We are now at the fruit-seeking stage, and there is no need to waste physical strength and energy in the game. Just go offline. I don't believe that the game still doesn't allow us to go offline to avoid the limelight! ”

Xiao Nan didn't care about knocking out the salty pig hand, and suddenly said in surprise: "That's right! Downline can also maintain hunger value. So what are you waiting for, hurry up and set up a tent! ”

This time, it was Xiao Nan who reminded Luo Yang. The two of them worked together as fast as they could, set up the tent, and then lay down and went offline.

After waking up from the game, Luo Yang found that it was early in the morning, and he had already spent a long day in the game.

He hurried to wash up and rush to the cafeteria. As soon as I finished cooking, I saw two familiar figures coming.

Luo Yang had a very tacit understanding of three meals, and Xiao Nan and Yan Nanshang also had a very tacit understanding and sat down with their heads on their shoulders.

Luo Yang didn't rush to talk about them, but asked Yan Nanshang with a smile first: "How is it, do you stay in the tavern?" ”

Yan Nanshang took a bite of the fritters before he said proudly: "It's okay, at least I found out that the real use of the fruit is not to add it directly, but to dry it and grind it into powder." ”

Luo Yang asked casually, but found that Yan Nanshang seemed to have really made some achievements. I can't help but be curious. But Xiao Nan obviously doesn't have that idleness.

"It's all going on for a while, and after eating, hurry up and hand over the things so that the professionals can crack it!"

Luo Yang asked, "Where did you tell her?" ”

"Basically, everything that needs to be said has been said!"

"That's a lot of saliva, where are we going to crack it?"

"What better place to do it than your library?"

Luo Yang gave a thumbs up: "Okay, you!" The head melon is not long in vain! ”

Xiao Nan glanced at her and didn't speak, and began to urge the two of them after eating breakfast in three or two.

At her desperate urging, the three of them managed to settle breakfast within five minutes.

Luo Yang began to clock in at work, while Yan Nanshang and Xiao Nan found a quiet corner. Soon, Luo Yang handed over a notebook.

"This is the nine-square grid I drew and all the number clues. Talented girl, it's not a problem for you! ”

Yan Nanshang didn't speak, opened the notebook and began to frown and think. Soon he was writing and drawing on calculus paper.

In less than twenty minutes, she tore off a piece of paper that had been filled out.

Luo Yang and Xiao Nan leaned over to take a look, and sure enough, it was the standard answer!

When the two of them were studying, they suddenly found that Yan Nanshang did not stop to explain anything to them, but continued to write in the notebook.

"What are you doing here, haven't you already written the answer?"

Yan Nanshang suddenly looked up at Luo Yang, as if he didn't understand that Luo Yang would ask such a stupid question.

"Sudoku usually has more than one answer, you don't even have this common sense, right?"

"Smack!"

The notebook in Luo Yang's hand suddenly fell on the table, and he suddenly realized that he had made a very serious mistake.
