Chapter 243 (1/2)

”Ah... Ha ha... ” The seal felt the corners of his mouth twitch, put the magnet in his pocket near the hole for comparison, and found that it was the right size.

He tried to put the magnet in, only to insert about a third of it. He felt that there was a strong magnetic pull in the round hole, which attracted the whole magnet. The next second, the box opens

It turns out that this small safe doesn't need a password at all. The front lock is just a cover up. The real way to open it is to trigger a mechanism inside. 80% of the safe is only made of ordinary metal materials, but inside the small hole, there is a special, high-density magnetic ore with a wedge inside. The only prop that can unlock this mechanism is the magnet.

”Constantly changing the rules of puzzle solving, right There is a kind of... ” Although I was a little annoyed, the seal soon calmed my mood. The big box outside was opened with a password, which doesn't mean that the small box inside should also be opened with a password. If he wants to blame, he can only blame himself for falling into the trap because of his fixed thinking.

Feng unconsciously took out [the key to 1F underground] from the safe, then left cell 6 and walked to the stairs leading to the upper floor.

After the black iron fence door is opened, the key disappears, and the system prompt rings at this moment: the task [current task completed, main task updated]

[explore underground 2F, open the door to the upper layer] is ticked off, and the next instruction appears: ”go to the ground 1F]

” hmm? ” Feng didn't realize it was strange when he saw this task. It should be said that the task should write ”explore the underground 1F and find the way to the ground”, but he only wrote such a simple sentence as ”go to the ground 1F”, as if

”Can we go straight up?” I don't know how to read.

He held the rusty long iron bar (which had already turned to dilapidated quality) and walked cautiously along the corridor 1F underground. This floor and the underground 2F are almost mirror image design, not far from the ladder. Six cells, three on the left and three on the right. But the iron door of the cell on this floor is different from the one on the bottom floor. There is no rice mouth, no small iron window, and no number marked with paint on the door. In addition to the keyhole and door handle, these six iron doors are almost one piece of iron with unknown thickness, and they can't find out the situation outside the door.

One by one, I tried to see if the six doors could be opened. As a result, they were all locked and listened to the door. There was no movement. He said in his heart: ”it's unlikely that the whole 1F underground floor will be decorated. That is to say I'll be back later, won't I... ”

As he pondered, he reached the other end of the corridor, where an upward flight of stairs appeared. Feng unconsciously calculated the length of the corridor according to his stride. He was sure that cell zero should be right below the ladder. However, his calculation does not seem to make much sense except that it can show that the corridor length of 1F and 2F underground is the same.

The steps in front of us are made of wood and look old. There are still many strange smells left on the steps. The source of those smells may be the food and feces spilled during the transportation, or the blood and body fluids left when people are dragged up and down. Mixed together, it becomes a kind of not strong. But it's disgusting enough.

Seal not to feel pick up the level and up, turn back once, on the face of a wooden door. He reached for the doorknob and turned it carefully. The door opened smoothly.

Behind the door is the ground floor. Standing on the stairs and looking out of the door, you can see a room similar to a storage room. The walls are made of brick and wood. There are many sacks with drums around. On one side of the wall are three rows of round wooden casks.

The light in that room is worse than underground. The only light source is a kerosene lantern on the barrel. Feng didn't realize that he would not rush into the dark environment ahead of him. He first extended his iron bar into the door, knocked it up, down, left and right, and made sure there was no trap launched by physical contact before stepping through the door.

[the current task is completed, the main task has been updated] the system prompt rings again, and the new task appears: [explore the ground 1f, find out the six keys of red, yellow, blue, black, white and gray, and then go back to the underground 1F to open the six iron doors]

after blinding and scanning the task, he continues to go ahead. The first thing he does is to get the kerosene lamp. When the flashlight can't be used, it is urgent to start lighting equipment.

He just walked out more than three meters, and suddenly With a bang, the door behind it closed.

Feng doesn't feel that he turns back suddenly, but only the closed door and his shadow on the wall can be seen in his sight. He listened attentively for more than ten seconds, but there was only suffocating stillness around him.

At this moment, he took out the King Kong bell and opened the special effect of ”death warning”.

In the next five minutes, anything hostile to Feng, which may threaten his life, will cause King Kong Bell's reaction.

However, he waited about 20 seconds after the special effects were turned on, but no ring was heard.

”Ho What is the situation... ” ”There is no wind in this kind of place, and it's impossible for this door to be equipped with a kind of closed door hinge with spring How is it closed without external force? ”
