"I don't think it's very likely to do it again. After all, I've already done it that way last time. ”

When Luo Fei said this, he instead increased the volume to the point that he should be able to hear it on the other side of the camera. However, the other side was still quiet, and it was obvious that Luo Fei's temptation just now was useless.

So Luo Fei continued: "When you reasoned out the direction of the room, she seemed very unhappy, not happy that you stole my limelight. ”

"But when I later said that I thought about the password from the content of the five line poems, she didn't get angry anymore, but looked equally happy!" Shen Ying was also a little puzzled.

"In the water room, when Su Ruoying went into the water to knock on the tiles one by one, she reminded me to think about how to narrow down the scope for Su Ruoying, and gave a hint of where the key used to be in the photo."

Luo Fei said his final judgment: "Of course, the above alone is not enough to show that she is worthy of suspicion. What makes me doubt the most is her control over our time from the beginning to the present! ”

"You're saying that once she feels we're slow enough to leave all the chambers in six hours, she'll help us speed things up in a very covert way?" Speaking of which, Shen Ying finally understood what Luo Fei meant.

"Yes. It is precisely because of the six-hour time limit that from the beginning to the present, we have been most worried about not being able to leave all the secret rooms within the specified time limit. But now it's clear that Zhao Yafei seems to be helping us all the time and not falling behind in terms of progress. But if that's the case, then what's the difficulty of this secret room? On the surface, we have reached this point on our own, but in reality? Could it be that even if we didn't think of those ways to get passwords before, Zhao Yafei will give us more hints and help us open one password door after another? When Luo Fei said this, the meaning he expressed was already very clear.

"But isn't our goal to escape from the secret room?" The existence of the camera made Shen Ying unable to say too bluntly: "Even if we can't understand why Zhao Yafei did this, the direction of the result is still good!" ”

"On the face of it, it is." Luo Fei looked up at the camera, but there was still no voice that Tang Xiaoxiao planned to participate in the topic.

At this time, there was the sound of footsteps in the earthen room, and soon Su Ruoying was carrying the backpack in the golden room, and Zhao Yafei came over with a metal clip, a metal beaker, and a shovel in the water room.

"Yafei is really amazing!" Su Ruoying put the backpack in front of Luo Fei, took out 9 gold bars from it and said to him and Shen Ying: "She quickly learned from the poem "Gold Pin Molten Water", as well as the metal beaker and metal clip in the gold room, that she could melt the gold bars and then use the beaker to measure the scale! I thought it would work, so I got all of this!! ”

Luo Fei's meaningful Shen Ying exchanged glances, but still nodded and agreed to try the method Zhao Yafei said.

So Shen Ying first carefully took out the charcoal burned inside with a shovel and put it on the ground to dry. Then he went to the wooden room with Luo Fei to completely split the wardrobe with an axe and get it to the fire room to replenish fuel.

Finally, Shen Ying used a metal clamp to clamp one gold bar into the furnace, and on the other side, put the metal beaker on the shovel and prepared it, ready to wait for the gold bar to melt and soften, and then put the metal beaker into it to receive water.

However, 9 gold bars may seem like a lot, and not only does it melt slowly in practice, but the metal beaker may not be able to fully contain the gold water that the gold bars may melt.

"This metal cup is really small, if only there was one gold bar!" Seeing that the first gold bar had not been burned for a few minutes, when Su Ruoying began to show an anxious look, Zhao Yafei looked up at the time on the wall, and suddenly said such a sentence.

"It's okay, we can just measure one, I think this gold bar is almost the same size, can you multiply it by 9 when the time comes?" Su Ruoying heard Zhao Yafei say this, and said with a flash of inspiration.

"That's not what she meant!" Hearing this, Luo Fei suddenly sneered, and his very cold expression instantly startled the two girls!

"Yes, I am!" Zhao Yafei, who was obviously frightened, spoke a little stumblingly: "That's what I meant." ”

"Luo Fei, what are you doing? You're scaring her! Su Ruoying was a little angry because of the sudden fright, she blocked Zhao Yafei behind her, and said to Luo Fei a little angrily.

"Your hint is indeed very useful, but apparently Su Ruoying has misinterpreted it!"

Luo Fei didn't change his expression because of Su Ruoying's anger: "Maybe it saves time to bake 1 gold bar than 9 pieces, but if one of them is specially made, wouldn't it be faster to bake the number with a fire?" ”

"There is indeed this possibility, but combined with the phrase "gold sells molten water", it is more likely that I am talking about it! Su Ruoying nodded: "Don't do this next time, have ideas to say, don't be scary!" ”

And Shen Ying also first changed a piece of gold bar to bake in the furnace according to what Luo Fei said, and replaced it with the next one after two minutes without seeing a number.

When the 4th block was changed, the gold bar was really different from the previous one!

It's just that instead of the numbers, everyone sees that this gold bar has a very low melting point, and it seems to be a specially made non-gold metal, which starts to soften not long after being roasted in a furnace.

"Quick, catch it with a beaker!" Luo Fei said as he stretched the metal beaker on the shovel into the furnace and went to assist Shen Ying himself.

As this "gold bar" began to melt into "water" until it was completely melted, Luo Fei took out the beaker with a shovel, and everyone saw that the scale of the metal beaker showing "water" at this time was exactly 80 ml!

So, the corresponding password is 8 or 0? But it's clear that 8 is much more likely. Su Ruoying said.

In fact, although the acquisition of the password is indeed directly related to the phrase "gold is sold and melted water", if there is no Luo Fei's suggestion to bake them one by one, I am afraid that Shen Ying will always bake the first gold bar, and the resulting capacity will be multiplied by 9, it will be 720, and on the premise of not wanting to explore the phrase "gold from soil deposits", it is likely to make everyone waste a lot of time.

"All that's left is to use this charcoal to smear somewhere in the dirt room?" Seeing that there were still about forty minutes left, Su Ruoying, who felt that the customs clearance was in front of her, was in a good mood, and she didn't care about Luo Fei's scary things before, and took the initiative to rub the slightly cool charcoal with a shovel and walked towards the earthen room.

Zhao Yafei hurriedly followed, and took the shovel to help Su Ruoying hold it.

"Does she really give us a more subtle hint?" Shen Ying didn't rush to follow, but stopped beside Luo Fei and whispered to him.

"Maybe she didn't expect me to get to the point of the problem directly, let's go and see if she will give us hints so quickly in the dirt room when time becomes abundant." Luo Fei meant to observe again, and beckoned Shen Ying to walk towards the earthen room with him.
