They were both still young, so without exerting all their strength, they could easily open the lid of the hole. The inside was a booth. Although the top of the building was about four meters from the roof of the building, the cubicle under the hole was not deep. The bottom of the booth was less than two meters from the hole they had just opened. Chioujen immediately jumped inside.
"Be careful, Sir!" Hannrong exclaimed.
"Don't worry Hannrong. I'm used to jumping around like this. You see, I'm okay, right?" Chioujen answered as soon as he landed in the booth.
The light coming in from the hole was enough to make Chioujen observe the booth. It turned out that the length and width of the cubicle were different from the length and width of the building above the service elevators. The size of this cubicle was only about four and a half meters by two and a half meters. So indeed, this booth was a space at the back of the service elevators.
In front of Chioujen was a staircase going down. This was very similar to the emergency stairs in the building. Only the stairs in this cubicle were much smaller. The cubicle part, which was the staircase, covered half of the cubicle. So the back of one service elevator was in the form of stairs, while the back of the other service elevator was an empty place that Chioujen didn't know its function. But what was clear was that the place could function as a place to rest.
"Hannrong! There are stairs going down here. I'll try to go down this ladder."
Hannrong stuck his head in the hole. "Isn't it dangerous, Sir?"
"It's all right! Dafeisy Tower is a new building. It was only built a few years ago, right? Now, can you please find some rope? So that later I can more easily climb out of this hole above!"
"Okay, Sir! I'll be down for a while looking for ropes."
"A little time is okay, too. Maybe it will take me quite a bit of time to explore each floor below," Chioujen said.
"Okay, Sir!"
"You don't have to close the hole. So, let there be light in here."
"Yes, Sir!"
Soon after that, Hannrong disappeared from Chioujen's sight. Chioujen realized he couldn't trust Hannrong one hundred percent. But no one else was there. If not Hannrong, who else should Chioujen turn to for help? After all, the problem of the secret room in this building was not something that should be covered up.
Chioujen took out his flashlight. He pressed the button to turn on the flashlight. Right now, he was feeling very excited. He moved down the stairs carefully. It turned out that it differed from the height of each floor in this building, which reached four meters. The height of each floor in the cubicle behind the service elevator was only two meters. So each floor in the building was equivalent to two floors in the booth.
Chioujen patiently descended the stairs. On every floor, the situation was exactly the same. There were only stairs and an empty booth next to it. Nothing else. The lower he went, the darker the place. The light from the hole above didn't even reach the floor where Chioujen was currently at. Good thing the flashlight was new. The battery was also new. So Chioujen wasn't worried at all. At least, for the time being.
About fifteen or twenty minutes later, Chioujen felt he was already on the ground floor. Of course, it was very possible that Chioujen had miscalculated. But it wasn't a big problem because Chioujen wanted to see where the stairs ended. Excitedly, he continued down the stairs. After descending a few floors, according to Chioujen's calculations, he should be on the B3 floor by now. But, there were still stairs going down in front of him. Meaning that it was confirmed that there was still a floor under the B3 floor. And that floor could be reached by stairs in front of him. Before continuing down to the next floor, Chioujen checked the booth beside the stairs.
Chioujen discovered something new. Unlike the rooms on the previous floors, which were completely empty, there was a couch in the cubicle next to the stairs. In front of the couch, there was a table. He put off his plan to go down to the next floor. Chioujen then sat down on the couch. With his hand, Chioujen touched the surface of the table. Both the couch and the table were relatively clean. Chioujen then tried to lie there. He fiddled with his flashlight to highlight the entire interior of the small room.
Chioujen tried to remember what he witnessed when he was on the B3 floor. The stairs end on the B3 floor. Based on the design drawn in the floor plan, there should still be stairs leading down. However, it could be that the stairs down had been dismantled. Many rooms on the B3 floor were locked. Some rooms were quite large. It was very possible that the staircase leading to the lower floor had been moved into one of the locked rooms. If that's the case, Chioujen needed to open all the rooms to find the position of the stairs.
This was impossible because it turned out that Hannrong didn't have all the keys to the rooms on the basement floors. However, at that time, Chioujen didn't have to bother looking for the keys to these rooms anymore. In front of his eyes, there was another way to descend to the B4 floor. The small staircase in the small room was probably a secret passage to reach the B4 floor, apart from the official staircase in one of the locked rooms on the B3 floor.
Chioujen suddenly remembered that Hannrong was most likely waiting for him on the roof of the building. He quickly got up and walked down the stairs.
<<This must be the floor between floor B4 and floor B3! I'll call this the B3B floor.>>
Just like the cubicle on the B3 floor, there was a couch and table in the booth next to the stairs. Now, Chioujen didn't stop what he did to trying to sit on the couch. He went straight down again to the next floor. Chioujen was excited to go to the floor, which was called the B4 floor in the building plan.
There was no couch in the cubicle next to the stairs on the B4 floor. There was only a door. For a moment, Chioujen hesitated about what to do. On the one hand, he wanted to open the door right away and face whatever he came across behind it. On the other, he realized he couldn't keep Hannrong waiting too long. After pondering, Chioujen decided to go upstairs first. He didn't know what he would find behind that door. Later, he will return with much more mature preparations.
