"This kind of thing can actually block all electronic devices, even the communication and detection effects of intelligent machinery...... It obviously looks so broken," Zhou Yuan looked back and forth a few times with his cloak, "and it doesn't seem to be anything special......"

"Be careful, this thing is precious, even the entire Overwatch, there are only a few of them. This time, Morrison decided to take this thing out after spending a lot of money. Moreover, this thing is a one-time thing, and after twelve hours it will turn into a normal cloak. ”

Anna senpai replied.

"Really......"

Zhou Yuan hurriedly put the cloak on his body.

Anna's predecessor usually wears that style of blue-and-white cloak, which is probably a cloak that has lost energy.

"Anna Senpai...... This is what you usually wear......?"

"Well, I used this cloak in one of my operations...... There are seven of these cloaks, which Overwatch had spent a lot of money on a large-scale projection phenomenon. I used one of them at that time, and the remaining six will be all used up tonight if nothing else. ”

After Senior Anna finished speaking, seeing that Zhou Yuan was still waiting for Senior Anna to continue to speak, he couldn't help but sigh.

"If you want to hear the story, I'll tell you later. Now, let's do tonight's action. ”

With the last incident, Blackclaw is bound to increase its vigilance and even its strength. Therefore, this time, the location chosen by Anna's predecessor to enter the Black Claw Underground Auction is...... In a dead end where there is no human figure at all.

"That...... Anna-senpai, are we really going to get in from here?"

Zhou Yuan looked at the sewer in front of him with a blank expression. The manhole cover of the sewer has been pried open by Anna's senior, and it should be possible to jump directly into it from here.

In fact, it is not very dirty, and there will be special machinery to clean it every day. Merely...... In any case, there is still a certain degree of resistance in Zhou Yuan's psychology.

"No nonsense, it's right to go from here," Anna replied, "there's a place on the edge of here that is relatively close to Blackclaw's base, and we can go from there." ”

After saying that, Anna was the first to turn on the flashlight on the gun and jumped down.

"Okay...... Looks like it's going to come in from here......"

Zhou Yuan shook his head and reluctantly jumped down. Soon, all the people jumped down with Anna's senior, and finally Mikoto Misaka used her electromagnetic ability to close the manhole cover of the sewer, and the place became a little-known alley, and there was nothing unusual to see from the outside.

After walking down the sewer road for about four or five minutes, we arrived at the place that Anna's predecessor had mentioned.

Well...... In front of him was a sleek metal wall.

"Okay, after the nine-meter metal wall, it should be the venue of the underground auction," Senior Anna took out the map, glanced at it and said, "Zhou Yuan, where is your backpack?"

Five-meter ...... At first, I wondered why I had a laser cutter in my backpack, but now it seems that ...... Nine meters thick, Anna senior, you actually told me that this is from here to the base of the Black Claw "relatively close"?

But fortunately, in the case of ordinary metal, there is no wall that cannot be cut by a laser cutter. In this way, even if it is nine meters thick, it will take a little longer.

The size of the laser cutter is not very large. The bottom surface of the laser cutting machine is made of a special magnetic substance that can attract most of the metal, and after sticking it to the metal wall, you can hold the handle with your hand and pull it slowly at a speed of no more than one meter per meter per minute, and you can cut all the metal regardless of the thickness, and it will only cause very little noise and sparks, which can be said to be murder and arson...... Ahem, one of the essential tools for righteous infiltration.

After Zhou Yuan pasted the laser cutter on the wall, a number 9 was automatically displayed on the laser cutter. This thing has a special function that can automatically detect the thickness of the wall, since the number on it is 9, then it means that the map should be correct, and you can enter from here.

Zhou Yuan grabbed the laser cutter and began to slowly swipe down. The speed of the laser cutting machine is that it takes one minute to cut one meter per meter of thickness, so the operation speed on your side is about nine minutes and one meter. But in fact, if you want to be able to pass through enough people, you can cut a cylinder with a diameter of about half a meter, so it doesn't take long.

Soon, Zhou Yuan drew the cutting line of the laser cutting machine back to the starting point.

"Alright...... So that you can ......"

"The cylinder with a metal thickness of 6 meters has been cut, and you are welcome to continue using the items produced by the Fisca Academy next time, thank you for using it. ”

Six meters? No, Anna's predecessor said that it was nine meters thick...... And here it is also shown on the monitor that it is nine meters......

Zhou Yuan raised the laser cutting machine in his hand and couldn't help but scold his mother. Since my right hand became a ghost hand, many things have been changed to be done by my left hand, and this cut is no exception - of course, under the two different ways of holding the left and right hand, the left and right sides of the switch are also different. Zhou Yuan, who is accustomed to using his thumb to start the switch, almost logically gave this symmetrical laser cutting machine to ...... Take it upside down. It just so happens that the display shows Arabic numerals, and then ...... Coincidentally, the number 6 became the number 9......

That is to say...... Finding the wrong place?"

Zhou Yuan took the laser cutting machine in his hand and said helplessly.

"That's not right...... If you find the wrong place, the wall thickness should not be three meters......"

Anna muttered.

That's right. If you find the wrong place, then you don't know how many meters thick, and it can't be six meters - no matter where the difference in this number is generated, there should be something inside after removing this pillar.

But...... Although Zhou Yuan had the power of the ghost hand, after cutting it, there was no point on this metal cylinder that could be grasped by hand......

"Please, Mikoto Misaka...... Can you help remove this metal pillar?"

In the end, Zhou Yuan could only helplessly ask Mikoto Misaka for help.
