After selling Hong Qingsong's treasure, he bought a lot of props, cards from the Three Kingdoms Kill, cards from Monopoly, guns from CSS, and props from the real-time battle arena of multiple players... However, all these props actually don't cost much.

The flashing dagger is the most expensive, with tens of thousands of points, and the others basically range from hundreds to thousands, so the cost of buying a bun is not huge. Among all the things, the most valuable ones are a few luminous cubes. They are obviously just one-time props, each priced at tens of thousands, which is about the same price as the flashing dagger that can be reused, and they completely consume the money they have sold.

However, there is a reason for being expensive. Looking at the three numbers on the cube, 289, 631, 541, Dugu Fu smiled with satisfaction and suddenly opened the door of the employee activity room.

In the open activity room, more than a dozen soldiers in the system were patrolling with guns, including several advanced players of the heavens, and it seemed... there was also an infinite stream of players.

Suddenly, I saw the door being opened. Regardless of whether there was anyone outside the door, I raised my gun and aimed at the outside in an instant. The control room was the key to the entire ship, and everyone knew it. In this case, of course, it was a heavy army to guard it and take it seriously.

However... when the door opened, no one just flew in and a large luminous cube with his fist. When it landed on the ground, the cube suddenly became bright, and light shot out from the surface. It did not hurt people, but just left dense square light and shadow on the wall, which seemed to be... scanning?

"Damn, the murder cube!" Someone instantly identified this kind of evil thing, and his soul was scattered for a moment, but it was too late.

The cube light and shadow just rotated slightly and finished scanning. Then with a "pop", the glowing box shattered, and the light spots drifted like fluorescent light, leaving no trace.

But disappearance is not the end, it is just the beginning. "Pick", as soon as the cube disappears, the door of the room will be closed. The next second, the blazing beams flash again, but this time, they are not emitted by the cube, but by the walls of the room.

It was like a complex large net, with a shiny beam of light slowly sweeping through one end of the room and heading straight to the other end.

"Puff!" A soldier in the system could not dodge and was gently swept by the net. The next second, his body suddenly broke into neat small pieces and collapsed with a bang.

"Ah!" The system soldiers, Tianren players and Infinite players all screamed in horror, but... what's the point? The killing laser beam swept over coldly and ruthlessly, and in the blink of an eye, they were all cut into minced meat.

[The murder cube, a prop from the terrifying escape small space of the same name, is a prize that only the winner can get. As long as it is activated in a confined room, the cube can convert the room into the corresponding room in the small space within the next three hours. There is no trap. If there is a trap, people will kill people! Ghosts will kill ghosts!]

So how can we know whether there are any traps in the room corresponding to the numbers on the cube?

We all know that if each number is not a prime number itself, it can be obtained by multiplying the prime number. The rule is actually very simple - as long as there is one in a set of three numbers, it is a number that only contains one prime factor, and there will be traps in the room.

If you explain it carefully for some math blinds, this rule actually divides into two situations.

One is that this number itself is a prime number and is a number that cannot be decomposed, such as 2, 3, 5, 7, 11... These. They cannot be decomposed, and their only factor is themselves, and they are their own one-way. So each prime number means a trap.

But in addition to this, there is another situation, that is, 4, 8, 16, 32, 9, 27... Although these numbers are not prime numbers, they are the multiple powers of the same prime number. 4=2×2, 8=2×2×2, 9=3×3, they only contain one prime factor, so there are also traps.

As long as you know the rules, it will not be difficult to judge whether there are any traps.

Hearing the screams in the room stopped, Dugu Fu opened the door of the room, saw the minced meat on the ground, and smacked his lips: "It's worthy of being a third-level dangerous house!"

What is the concept of a third-level dangerous house? It refers to a room where the trap of an agency is extremely dangerous and as long as people are inside, it is impossible to survive.

How to judge this?

This is not the original rule of the murder cube game, but the human designer added after the small space is established. The original rule is that as long as there is a number that meets the requirements, there will be traps in the room; the new rule is that the more numbers that meet the requirements, the more dangerous the room is.

A room with a number that meets the requirements is fast and quick, and there is still a chance to run away; a second-level dilapidated house is very thrilling; as for the third-level dilapidated house... everyone has seen it.

289=17×17; 631, 541 are all prime numbers, so Dugu Fu used such a three-level dangerous house to instantly clear the tightly arranged activity room.

Running along the bridge tower, in a few seconds, he came to the control room below, sorted out the gourd, and used another level 3 dangerous room to clear the inside, which was so relaxed that it was unimaginable.

This leaves only the lookout room directly above. It is also the easiest, because the lookout room is the smallest and the defensive power is the weakest, because if the rebels come over, they will definitely come from below and have to pass through the room below to get here.

The last room cannot be done with the previous method. Because if it is also arranged into a trap room, there are only three roads entering the cab, and it is all blocked. How can he get in?

When I arrived at the door of the observation room, I suddenly opened the door.

"Boom! Boom! Boom! Dada..." The fierce guns and cannons suddenly rang out, deafening!

The defenders in the observation room had obviously received a reminder from the other two rooms. Even if they didn't, they saw the mess and speculated that Dugu Fu might use. They were not in the room at all, but retreated to the cab below, poked out from the hatch, and gathered fire through the room. In this way, the murderous cube would not hurt them.

The idea is very good, but... why did Dugu Fu leave this room alone?

The firepower of resistance cannot last forever. When the firepower is slightly weaker and the person inside looks at it to see if he hits him, he suddenly flashes out.

[Flashing Dagger]! With a flash of 12 meters, he flashed from the door to the escalator in the blink of an eye, dodging all possible stray bullets. The next second, he jumped high, kicked with his legs, kicked with his feet, and kicked with Xingyi Harrier, and kicked with the sky!
