After Liu Siyong checked the ingredient rack and freezer, he searched carefully in the kitchen.

At this moment, the kitchen lights were turned off, and with the faint light of the corridor, it was impossible for him to rummage through every corner of the kitchen! Fortunately, Liu Siyong himself did not have such plans, and he went straight to the four walls of the kitchen with a clear goal. Flip around quickly in the same position as the human body!

"Found it!" He had just been touching the side of the wall at the kitchen door for a while when he came across a rigid board clip, A4 size, with a stack of printer paper on it.

Liu Siyong took off the clip, moved to the door near the corridor, and flipped through it by the light. Not surprisingly, this is a kitchen work notebook detailing what food was made on a given day and how much was consumed...... When he flipped back to the day two weeks ago, he found that a "new entry" had been added to the inventory record!

Liu Siyong's mind moved, and he immediately flipped it quickly, and on the basis of this day, he flipped over the term for a whole month, and sure enough, there was another "new storage record" that was almost the same!

Mozhank's ingredient delivery is once a month! This is enough for Liu Siyong to deduce that the next delivery time will be two weeks later.

Putting down the splint and hanging it back in its place, Liu Siyong changed places again and began to grope - he lay directly on the ground and began to check the floor little by little!

This time, his luck was not so good, and he didn't find the clue right away, but groped for nearly a quarter of an hour before he felt a crack on the floor in the middle of the kitchen. The seam is the interface between the alloy plate and the tile floor, and the tile and the alloy plate are obviously not sealed, and the seam is very deep.

Liu Siyong's heart moved, he used both hands at the same time, and touched back and forth along this seam, and now, he also had a general impression in his heart!

It is a square alloy plate with a length and width of about 1.5 meters, or rather, it looks like a basement door that can be opened by pushing and pulling. At one end of the alloy plate, Liu Siyong had already touched a concave place, just enough to put down his palm to pull, tried it, but did not pull a minute, obviously, it was locked.

Then, next to this recess, I felt another keyhole, which was obviously used to insert a key. At present, the door of the ground could not be opened, so Liu Siyong lay on the metal plate, put his ear on it, and then gently knocked on the metal plate.

"Knock knock ......" came with a muffled sound, the sound was hollow, and it could be transmitted deep downwards until it was silent.

Liu Siyong can already be sure that there is a passage under this metal plate.

Of course, this passage could never have been used for prison escape, or was developed by criminals. But even if Liu Siyong doesn't open this door at this time and doesn't go down to investigate it himself, he can be sure that this passage can lead outside the prison!

Why?

As early as when Liu Siyong found the clue "kitchen" left by the old turtledove, and learned from Huang Hu that the old turtledove was responsible for finding the escape channel, he naturally thought that in the kitchen of the prison, there is a high probability that there is a road to the outside of the prison.

However, this road could never have been "created" by the old turtledove! It's not Shawshank either, which gives the prisoner room to dig a tunnel to freedom. This road should be in the prison itself! And, it must have served some purpose.

Now, when he touched this door with his own hands, he finally understood that the tunnel behind this door should be the transportation passage of the entire prison!

I don't know how many people will notice that in some large amusement parks (like Disney), you will never see a truck driving on the main road, or any means of transporting goods to and fro. That's not because these materials were delivered in advance when the park closed, but because such a large amusement park uses underground passages to transport materials. All items are taken underground, which is not only convenient and fast, but also avoids occupying tourist passages and ground resources.

In the same way, Mozhank has taken this approach - the prison is a heavy prison, and according to conversations with coffee beans, it was built in the desert more than 100 kilometers outside the famous desert city of Firebird City, and is basically "isolated from the world". Considering these circumstances, it is more reasonable to ship items once a month. When the trucks are transported to the prison area, they turn into an underground passage.

Liu Siyong vaguely came to this conclusion as early as when he saw the word "kitchen". Then, after carefully observing for a long time, and communicating with the coffee beans on the side, he determined that "no trucks have ever come in this prison, at least no one has seen it". And Liu Siyong, who was born as a planner and once planned large-scale activities for the Dream Valley Amusement Park in SZ City, has long linked the two things together.

This adventure came to the kitchen to verify this! At this time, he knew the existence of the cargo channel, and grasped the time of the next delivery of goods, and a plan immediately came to his mind.

Of course, this plan still cannot be completed by him personally, and it is imperative to continue to cooperate with Huang Hu.

Liu Siyong did not delay, he quietly returned the same way, leaving no trace. Before returning to the confinement room, he quietly passed by the fat guard's monitoring room. At that time, the fat man was still lying on the table, making strings of snoring sounds. Liu Siyong came to him lightly, deleted all the half-hour footage in the surveillance, and then temporarily turned off the camera and adjusted it to automatically turn on after five minutes.

After doing all this, he crept back to the confinement chamber, and the fat guard was still dreaming.

The next day, when the fat guard in charge of monitoring was woken up by Captain Duke and asked about last night's situation, the fat prison guard didn't find anything unusual at all, he didn't even look back at the surveillance, let alone find that last night's surveillance video was cut away for half an hour. In the face of Duke's routine questioning, he did not hesitate to pat his chest to make sure he was okay.

Subsequently, Captain Duke opened the confinement room, and when he saw Liu Siyong staying inside, he did not have any suspicions. After a set of procedures, Liu Siyong was taken out of the confinement room and returned to his cell - overnight, the prison guards finally repaired the fault of room 38 and restored the smooth flow of sewers.

There was still a stench in the room, but fortunately, the stains on the ground had been cleaned up, and Liu Siyong could only endure the sin he had created.

At lunchtime, he revealed the news that he wanted to meet Huang Hu again to Coffee Bean.

The coffee bean was very excited that Liu Siyong finally had a reply, and it seemed that he was confident, which made the long-awaited coffee bean difficult to hide his joy.

But he also couldn't help but ask about the specific situation - when the two of them exchanged ears, they were still monitored by D.T's subordinates, and Liu Siyong definitely couldn't say it too clearly, but hinted to the coffee bean that the plan had been implemented and asked to talk to Huang Hu again.

After that, three days later, still in the visiting cell, Liu Siyong saw the dressed lawyer Goodman again, and the two smiled at each other - the old routine, Liu Siyong also cooperated with the performance, picked up the microphone, and talked nonsense without a match.

Sure enough, not long after he sat down, Huang Hu's voice came from next door - this time it was Huang Hu who sat in the innermost position first, and waited for Liu Siyong for a few minutes:

"You've figured out the clues of the old turtledove?"

The time for visiting the prison is limited, Huang Hu didn't talk nonsense, Liu Siyong was also straightforward, and said in a low voice: "There is indeed a passage that leads to the outside of the prison, but there are some restrictions......"

"First, the passage is usually locked, and it won't open until nine to ten a.m. eleven days later (this is the time of arrival of the customary deliveries from the kitchen log sheet), and we have to get stuck at this point in time to enter the passage."

"Second, the location of that passage must have been there at that point in time, but there weren't many of them, and they weren't guards, so it shouldn't be difficult to get those people. The difficulty is to get them without alarming the prison guards...... So, I suggest that while we are acting, we should create a little 'trouble' in another part of the prison to attract the attention of the prison guards and buy us time......"

"Thirdly, there will be cars in that passage for us to evacuate, but it should be trucks, and it will never be too fast and it will be very eye-catching. Once we escape temporarily, there is a high probability that the prison side will react and will be caught up quickly...... Therefore, after leaving the prison and before entering the desert, someone must answer and change cars. ”

After saying the three things, Huang Hu was silent for a while, obviously memorizing and digesting this information. After a while, he said in a serious tone:

"You know, if all this is arranged, and in the end the operation fails, and we will never have a chance to escape."

Huang Hu's words are both a fact and a threat. But for Liu Siyong, isn't this his only chance? The threat of death was imminent, and he was giving it his all.

"I've already gone to investigate it myself......" Liu Siyong thought for a while and replied to Huang Hu with this sentence. Although the words are still unfinished, he is telling the other party that he can get the opportunity to investigate in person, and his means should not be underestimated. Again, his plan was by no means child's play.

"So, how do we meet?" Sure enough, after saying this, Huang Hu only hesitated for a moment, and then turned to ask about the next step-which shows that he chose to trust Liu Siyong. It's just that he and several other accomplices are not in the same district as Liu Siyong, even if the other party knows the time of the action, where should they go to gather? How to ensure the tacit understanding of action?

Liu Siyong smiled silently, although Huang Hu had confidence in him, he was still testing the location of the passage he mastered. So, Liu Siyong said in a prepared tone:

"As long as you put yeast in a confinement cell before the day the plan is executed. I'll take care of the rest. ”

Liu Siyong will definitely not say the specific location, after all, the cooperative relationship is not strong enough.

After speaking, Liu Siyong added, "Don't make it too obvious, it's better to go in batches......"

"Understood." At this time, Huang Hu's side was very simple - since he chose to trust the other party and the other party gave a solution to the problem, then he should not ask in detail with interest. Anyway, the other party also understands the consequences of the failure of the plan.

After explaining all this, the two were taken away separately as if they were strangers, and only when they left, they quietly exchanged a look, and that look was by no means calm as usual - they all knew that the next time they met again, it would be the most critical moment of fate!
