After entering December, with the help of Penelope and Hermione, Darren finally completed the first result of manufacturing the magic eye, which has the detection equipment of perspective ability, because his magic photography equipment company, which has been converted from the production of magic telescopes, can provide some help in this regard and make use of some of the equipment.

After testing, the first prototype could see through objects of a certain thickness, but because the problem of the control system was not solved, the intensity of the perspective could not be adjusted at the moment, which undoubtedly greatly limited its practicality.

However, there is also an unexpected bonus, that is, Darren found that the working principle of this detection spell has nothing to do with optics, so it can be used normally in a completely lightless environment, isn't this a night vision device! After testing prototype No. 2 in the tunnels of the Slytherin chamber, he couldn't help but sigh that if this had been done a few years earlier, why did it hit the wall so badly in the first place......

In addition, Penelope also told Darren that he had received an order for the air-piston AR he had developed in the United States during the summer vacation in cooperation with that firearms company, and the Seal Six team had placed it.

Now that the US special forces are fully equipped with the M4A1, on the whole, they are relatively satisfied with its accuracy and power, but now they have a new problem, and the war in Bosnia-Herzegovina ended in November this year.

Clausewitz said in "On War" that "war is a tool of politics", so the cessation of war does not mean the end of all problems, but the continuation of another form, so it is not surprising that the US special forces, SEAL 6, were deployed to Bosnia to carry out the task of arresting war criminals.

In this kind of operation, the requirement for secrecy is particularly important, since it is sneaky, naturally can not make too much movement, although the M4 is shorter than the M16 as a standard rifle, but after adding a silencer, it is not the same thing, anyone who has played shooting games knows that the silencer is not a small section, and it needs to be equipped with a shorter barrel to reduce the volume of the gun, which happens to be a short assault rifle, and before Darren deliberately looked at one of the advantages of the gas piston AR, there is no "d" (excess gas) is more prominent.

In fact, the reason why Darren chose to enter the firearms market is that the focus is this, he knows that the special forces will definitely take a fancy to this weapon, after all, this is the choice of history, although the price sold to the special forces may not be too high, but there are many of them, there are several in the United States alone, plus the special police of various police stations, but it is a big piece of cake, and once the market share is opened, it will have a blocking effect on similar products, even if the performance of the other party may be better, But there is also a problem of operating habits, otherwise the later special operations forces combat assault rifle (SCAR) would not be able to push it down.

In addition, the advertising effect of special forces is super strong! In the United States, cosplay special forces weapons, that's a fashion, like a supermodel in a fashion show...... It is conceivable that with the use of the SEAL Six, the air-piston AR will spread among the special forces, and then there will be a huge civilian market, and the United States claims to be "300 million people and 200 million guns", which is not a joke!

By the way, "the branch in the UK also received an inquiry from SAS and SBS about whether it could provide a product for the air-piston AR," and sure enough, it is a country that closely follows, and the special forces will definitely act together...... Now, at least the source of individual weapons is not a problem!

But as the end of the month approaches, a question is also in front of Darren, how to spend Christmas? Thanks to Umbridge, almost all the students at Hogwarts leave school, but that also means that a full three weeks of vacation are wasted, and although he can almost ignore anything, but in terms of time, there is really no such luxury!

Although Hermione wanted to stay, she didn't spend much time with her parents during the summer vacation, and with Umbridge, Hogwarts wouldn't be a good place to vacation, and Darren told her that he would find time to see her, and that it wasn't a difficult thing to do now, and there were ways to do it.

Then, on the night of the event, Darren was awakened by a scream in his sleep, it was Harry.

Darren jumped out of bed and rushed to Harry's bed, where he writhed on the bed as he screamed meaningless babbles, wrapping the sheets all over his body in a cold sweat.

"Harry! Harry! Both he and Ron struggled to wake Harry awake, and he finally opened his eyes, then clutched his head and rolled to the edge of the bed and threw up.

"He's really sick," said a frightened voice, of Neville, "to call someone?" ”

"Harry! Harry! ”

Harry inhaled and propped himself up from the bed, "Your dad," he said to Ron breathlessly, "your dad...... Something went wrong......"

"Shhh Hearing this, Darren gasped, he knew that this was the message that Harry had received through the alliance with Voldemort, and it was absolutely fine, but what did he say to Ron? What's more, Moody hasn't taught him Occlumency yet, so he can't stand the idea of being obsessed with him.

"What?" Ron clearly didn't understand.

"Your dad! He was bitten, it was bad, there was blood everywhere......"

"I'm going to call someone," Neville said, running out of the dorm.

"Harry, buddy," Ron said, incredulously, "you...... You're just dreaming. ”

"It's not!" Harry said furiously, "Not a dream?? It's not your average dream...... I was there, I saw ...... I it......" Then he vomited again, Ron ducked back, and Darren quickly used his wand to clean Harry's vomit and then went out to get him some water.

"Harry, you're sick," he heard Ron say uneasily, "Neville has gone find someone......

"I'm fine!" Harry choked and wiped his mouth in his pajamas, shivering, "I'm not sick, it's your dad to worry about...... We're going to find out where he is...... He bled profusely...... I am...... That's a big serpent......"

Darren brought the water back, but Harry's hands were shaking so he couldn't hold the glass, so he could only take a few sips of it on his feet, and then sit on the bed shivering, and the sound of hurried footsteps on the stairs and Neville's voice.

With Neville was Professor McGonagall, "What's wrong, Potter?" Where does it hurt? She asked with concern.

"It's Ron's dad," said Harry, "he's been bitten by a snake, very badly, I see!" Professor McGonagall's dark eyebrows furrowed.
