Winter nights, cold winds hit.

A rack of energy radiators is running at high speed, so that the inside and outside of the house are completely two temperatures in winter, and many people are a little lazy to go out.

The huge Zhang Mansion is busy.

A while ago, there were people who kept having accidents inside and outside, which made people panic, and the 50th birthday of the head of the family, who had already entered the preparation period, was also suspended.

However, the terrifying killer has stopped, and the lady insists on Chong Chongxi, this birthday banquet continues to be prepared, and seeing that tomorrow is the right day, the house is busy up and down.

But Zhang Luosheng's mind is not on this.

Now that Luo Tong is in turmoil, and the second brother's position in the city guard army is somewhat unstable because of infighting, the Zhang family can only come up with a large amount of money to support the relationship.

The biggest headache is the third brother's side, after Tianwu was disabled, the third brother, known as the "greedy wolf", couldn't be honest, and incorporated two minor monk groups to reorganize and train, and he couldn't support his side for the time being.

Fortunately, there are still a few 3-star doormen available in hand, otherwise don't want to complete the task assigned by the eldest prince.

It's just that this hateful boy Xia Yu has been hiding by Qu Bailing's side, and it's very difficult to deal with!

Jingle ......

I was in the study, and no one would bother me if there was nothing important at this time, Zhang Luosheng frowned, and pressed a button on the desk.

"The head of the family, the hook has missed!" Fan Lu saw that Zhang Luosheng was a little displeased, and his heart tightened, but he still told the matter honestly, and then said tentatively: "The hook describes, the person who appeared later has a very strange aura, and it must be above 3 stars, very similar to ......"

"Like what?"

"Dark Guard, Hook didn't dare to strike again, because that woman is very much like a high-ranking Dark Guard. ”

Zhang Luosheng was a little irritable and knew what Fan Guan meant.

If the person who protects that kid's sister is really a 3-star level secret guard, I can't tell the identity of this brother and sister, and I can't afford to provoke it at all.

Plus a new ultra-long-range attack weapon that can take out the "Mauser" and even the assassin in the shadows...... Is it really related to the Song family?

For the first time, he was a little remorseful.

It's just that the feud was concluded early, and the eldest prince directly issued a strict order, and there were only two days......

"I know, you don't need to arrange for someone to tempt this matter, I'll arrange it myself. Zhang Luosheng thought for a while, and then said: "Give me a detailed report on the recent whereabouts of that kid." ”

Fan Lu was stunned when he heard this: "Yes, the head of the family!"

............

After more than two months, Morrow finally breathed a sigh of relief.

Xia Yu always didn't show up, but then he called him again, and he took a total of 600,000 euros from Xia Yu before and after, which made it rare for him to be in the poverty line, not only replaced the main modulation instruments in his hand with new ones, but also hoarded a lot of materials.

After a period of painstaking experiments, Morrow finally concocted the "Black Burst Powder" to a satisfactory state, and finally made a "flying cannon" that he was quite satisfied with.

Well, Xia Yu's little mention can be regarded as a small help to set the direction for himself, which makes Mo Luo wonder if Xia Yu has ever seen or engaged in the research of "black explosive fans".

Forget it, what's the matter!

He took the last bit of money to find a remote test site and try it, the attack power of this flying cannon is quite amazing, in the best state, almost two cannons can burst the military's standard defensive armor, which is more powerful than the original promise with Xia Yu!

I heard many people mention, what "Sun Armor Piercing Cannon" made a big splash a while ago?

This is its own flying cannon that has not yet come out!

Therefore, when Xia Yu suddenly appeared in front of him, Mo Luo was stunned for a moment, and then a look of pride.

"You succeeded?" Xia Yu was indeed a little excited.

In his first plan, gunpowder was a crucial part. If Morrow didn't figure it out, he wanted to try it himself.

"Would you like to try this, you must be strong!" Moreau handed him an arm-thick alloy barrel about two feet long, similar to a solo bazooka, but one size larger.

Next to it, there are several different types of shells, and it can be seen that Moreau has indeed put a lot of effort into it.

"What are the requirements for perception in this fight?" Xia Yu asked.

"Ha, this is the uniqueness of this genius, to tell you the truth, this flying cannon is very simple to control, almost as long as the perception of ordinary people can be controlled, of course, to hit accurately, you still need special training. "Moreau was excited, a little bit talkative.

"Hehe, I'm afraid it will take a long time to train, and it's a bit strong on the body, I'm afraid that ordinary people can't stand a few can......'t stand it."

With Xia Yu's mechanical knowledge, he only glanced at it, and found that although this flying cannon has achieved the basic high-seal firing function, not only is there no shockproof pad, but the scope is simpler to only have a single lens, and even the design of the limiting rod is too simple.

Xia Yu estimated that he had only tried to send a few, and the error rate would increase a lot in the long run.

"It's all a trivial matter, and I'm still improving......" Xia Yu pointed out the key points at a glance, Mo Luo was a little embarrassed, "Give me time again, these problems can be solved!"

"How much more do you need?" Xia Yu asked him directly.

"200,000...... No, 100,000 our should be enough!" Moro scratched his head, his tone much lighter.

"This is easy to say, but I'm more interested in your 'black fans', take me to see it!" This is Xia Yu's goal this time.

"Hey, this is easy to do, it's not good to take things, I haven't prepared much, but I still have some stock, you wait for me to get it......"

"Let's go together!"

I have to say that Moreau is an alternative genius.

The new version of "Black Burst Powder" that Xia Yu saw was already very similar to the gunpowder in his impression in terms of condition, and after testing it with a special one, the explosive power was already quite amazing.

In this way, although Xia Yu has a little impression of nitroglycerin, a modern gunpowder, he really can't remember and don't have time to learn from the famous Nobel Prize to develop a safe way to make nitroglycerin.

Fortunately, the power of this old-fashioned gunpowder researched by Morrow is already quite good.

"Morrow, I have something recently, I need a lot of gunpowder, well, it's black burst powder......" Xia Yu lowered his voice, "It roughly takes more than 20 kilograms, if you rush to work now, how much time will you need?"

"20 pounds?"

Moreau was taken aback by this number, he knew the power of this "black pop fan". With a small piece of sealed metal canister, it can cause a violent explosion if it manages to ignite.

He didn't dare to apply for a patent for this dangerous weapon that subverted the system of the source energy mechanism, and he didn't even plan to sell the flying cannon on consignment.

"Yes, Moreau, I need your help. ”

Feeling the resoluteness of Xia Yu's tone and the implicit heavy grief and indignation, Mo Luo roughly estimated his configuration process in his mind, and said: "I still have enough materials here, give me a day, and I will configure 20 catties of black explosive powder for you!"

He didn't want to ask Xia Yu what he wanted to do, even if he was going to kill someone, what did he have to do with him?

"Thank you, but my matter is urgent, if I am with you, can I get it done tonight?" Xia Yu said.

"So urgent?" Morrow frowned slightly, "Okay, you give me a hand, let's fight!"
