In the face of Miao Yufeng's beating and crying, Lu Dashi didn't hide, just smiled and endured, anyway, Miao Yufeng's little fist was not powerful.

After a while, Miao Yufeng stopped thrashing and asked in a low voice.

"Brother Lu, what should we do next!"

Lu Dashi thought about it before he said slowly.

"Although, Du Qingyu will find this passage and come to rescue us immediately, but we can't sit still, in case Du Qingyu drags on for a long time, I'm afraid that before they come to save us, we will both starve to death."

As he spoke, Lu Dashi had already stood up and walked towards the gate of the main passage, saying as he walked.

"So, we still have to think of a way, and wouldn't it be better if we found a way to open the door inside."

Standing in front of the big iron gate of the main passage, Lu Dashi pondered.

The person who lives in this secret room should be the Jiangnan Seven Wolves mentioned in the letter.

Lu Dashi was a little unconvinced, the Seven Wolves of Jiangnan would build a big iron gate that they couldn't open.

This is not like what is written in a certain part, as long as the broken dragon stone at the mouth of the passage falls, it will never be able to get out.

The point is, there is no point in making such a door that they can't open themselves, except for being able to shut themselves in, there is no use.

Therefore, Lu Dashi guessed that in this secret room, there should be a mechanism that can control this big iron gate.

To be honest, Lu Dashi really wanted to go out immediately.

He is tall and burly, which also means that if he can eat, he will naturally be hungry quickly.

The two of them had been trapped in the secret room for so long, and Lu Dashi was already so hungry that he couldn't wait to pick up a stone from the ground and throw it in his mouth to eat.

In particular, Du Qingyu, this kid, is not very reliable no matter how you look at it.

In case he found the secret passage, but did not come in, but waited until dawn to enter, and then after searching for a while, he saw this door, hesitated for a while, thought of a way, and the time of the day passed.

Wait for Du Qingyu to return to the city, stay in an inn for another night, and come back tomorrow when he is full of food to find a way to .......

All in all, if Du Qingyu could only open this iron gate after four or five days, Master Lu didn't believe that he could survive for four or five days and still be alive.

Therefore, it is best to find the exit mechanism while you still have the physical strength and take the action of self-help.

Of course, these words must not be said to Miao Yufeng, a stupid girl, otherwise, she may not know what will happen!

Looking at the big iron gate at the entrance of the passage, Lu Dashi pondered, where is the mechanism that opens the door?

There is a groove on the wall to the left and right of the gate, and there is an oil lamp on each groove, and it stands to reason that these two oil lamps should be the mechanism for opening the door.

However, these two oil lamps Lu Dashi have already touched them in various ways.

For example, grab the oil lamp and twist it left and right, or pull it outward, press down, it's useless.

Lu Dashi has used more than a dozen methods, but there is no response, which proves that these two oil lamps are definitely not the mechanism for opening the door.

So, where is the mechanism?

Now there is no other good way but to find it little by little.

Lu Dashi began to lean against the wall, carefully looking for the mechanism to open the door.

Lu Dashi checked very carefully, looking for it almost inch by inch, but he still didn't find the mechanism to open the door.

In the end, Lu Dashi put his eyes on the monk sitting against the wall, and pondered in his heart.

Could it be that the mechanism that opened the door was behind the monk?

After thinking about it, Lu Dashi slowly walked to the monk's side, squatted down, and was just about to move the monk away, when he suddenly felt that the light in the room suddenly dimmed.

Seeing this, Lu Dashi was suddenly shocked in his heart, and he groaned slightly, he immediately understood that this was the oil lamp on the table, and there was almost no lamp oil.

Due to the hurry of coming out, Master Lu didn't bring anything like a fire excerpt, and he also believed that Miao Yufeng wouldn't bring anything like a fire excerpt.

If this oil lamp goes out, that is, they have no fire source and can only grope in the dark.

Thinking of this, Lu Dashi hurriedly shouted at Miao Yufeng behind him.

"Miss Miao, hurry up and add some oil to the oil lamp on the table, otherwise, the oil lamp will go out!"

"Hmm!"

When Miao Yufeng heard this, she hurriedly agreed, turned her head and walked towards the table.

Seeing that Miao Yufeng had gone to refill the lamp oil, Lu Dashi was relieved, turned his head again, moved the monk away, and checked the wall behind him and the place where he had sit.

At this time, the light in the secret room suddenly shook a few times and went out.

Lu Dashi was shocked when he saw that the secret room had become dark, he never expected that Miao Yufeng would mess up such a simple matter as adding lamp oil.

Just when Lu Dashi wanted to ask, suddenly, a creaking sound sounded.

Hearing this voice, Lu Dashi was even more frightened, hurriedly stood up, touched the darkness, and touched the table, and at the same time, kept shouting in his mouth.

"Miss Miao, where are you, did you hear me, come here, come to me."

As soon as Lu Dashi's words fell, he felt that a person bumped into him, Lu Dashi subconsciously, reached out and grabbed Miao Yufeng, and asked hurriedly.

"Is it Miss Miao?"

"Hmmm! Brother Lu, it's me, it's so dark, I'm scared, woo! ”

Knowing that Miao Yufeng was fine, Lu Dashi was a little relieved, and then asked.

"What happened just now, why did the oil lamp go out?"

Hearing Lu Dashi's question, Miao Yufeng replied aggrievedly.

"Brother Lu, I really don't blame others, people just want to bring the oil lamp over and add some lamp oil, but the oil lamp can't be moved, and as soon as people turn around, the oil lamp will go out."

Hearing this, Lu Dashi's heart suddenly moved, and he immediately held his breath and listened to the source of the creaking sound.

After a while, Lu Dashi suddenly shouted, then patted Miao Yufeng hard, and said with a laugh.

"I'm not wrong, you stupid girl, it's my lucky star, thank you, my little lucky star, we can finally go out!"

As soon as Lu Dashi's words fell, Miao Yufeng's joyful voice immediately came from the darkness.

"Really? Brother Lu, is it true? Can we really get out? ”

At this moment, Lu Dashi's mood can only be expressed in ecstasy.

Because he had already heard it just now, the source of the sound was the entrance of the passage, and if he was not mistaken, the oil lamp on the table was the mechanism that opened the entrance to the passage.

I really didn't expect it!

Lu Dashi patted his head in remorse.

The more things are put on the surface, the less likely they are to attract the attention of others.

Thinking about it, no matter how careful Lu Dashi's mind was, he didn't even realize that the oil lamp that had been in front of them turned out to be the mechanism that opened the door.
