"Could it be that this No. 1 pops up a problem?" Mo Luo muttered, and without waiting for Xia Yu to speak, he threw out another No. 1 bomb and threw it out.

Rumble!

There was another loud bang, but I don't know what stone the floor still hadn't been blown apart much, only a few dust accompanied by the pungent smell of gunsmoke.

"What the hell!" Mo Luo didn't believe in evil, and just wanted to take two more and throw them together, Xia Yu grabbed his hand, and said with a smile: "Enough is enough, you look at the damage value on the screen over there, this power is already okay!"

"Huh"?

Mo Luo looked in the direction of Xia Yu's finger, and sure enough, there was a huge screen diagonally above, with two big red characters flashing "1106" and "1198" on it.

Shame on you!

When have we ever been to such a high-level training ground!

Next to him, Lu Qingyun's eyes lit up: "This No. 1 bomb is a triggered explosion, right? It can reach a damage value of more than 1,000, which is really good! But will it be very troublesome to store and transport this kind of device?"

Xia Yu saw that Lu Qingyuan saw the key at a glance, nodded and said, "You don't have to worry about this, I set up the trigger fuse, and there are two insurances." There are isolation structures, as well as shields, centrifugal hammers, firing pins and other devices, which require recoil and a certain degree of rotation after the firing pin hits the projectile to detonate. I won't tell you the specifics, but it's still relatively safe overall. Would you like to try it?"

Xia Yu was like an arms dealer at the moment, and directly handed one over to Lu Qingyuan.

"It's a little interesting...... Lu Qingyuan took the No. 1 bomb, and subconsciously released his perception to investigate, and sure enough, he didn't find any traces of the source array structure and source crystal, but it was the mechanical structure of the trigger fuse that Xia Yu said that caught his attention.

In the inheritance and study of the mechanism technique, the importance of the source array is far more important than the mechanical structure, but the things he has learned are very complicated, including the mechanical structure that many mechanism monks do not pay much attention to.

Soon, he saw that this mechanism for "triggering the fuse" was not as simple as Xia Yu said.

The precise setting and interlocking linkage test the level of mechanical structure.

"Awesome!"

He couldn't help but praise it, and then threw it a little unaccustomedly, and after another explosion, the damage value on the screen was 1120.

"It's almost stable in this range, let's try the No. 2 bomb!" Xia Yu gave Mo Luo a look.

"Okay!"

Moreau was even more energetic this time, bursting a bundle of "detonators" from the box and running away to put it away, spreading the fuse, and then running back.

"That's it?" Lu Qingyuan wondered.

"Hehe, don't worry!" Morrow took out a common ignition on the market from his arms, sensed a slight movement and ignited it, and then threw it towards the fuse with force, and then shouted: "Get down!"

Rumble!

This time, the sound of the explosion was more than ten times stronger than before, and it was not only the ground made of any material that was blown out of a large hole that was not more than a meter wide and more than a meter deep, and the smoke and dust were even more billowing and terrifying.

Lu Qingyuan was also taken aback, but he stood 30 meters away, except for feeling the violent vibration of the entire training ground, the aftermath of the air shock was nothing to him.

Of course, the violent roar still made the eardrums a little unbearable.

His gaze quickly fell on the screen above.

"36820, it actually reached more than 30,000!" Lu Qingyuan muttered: "A 2-star protective shield with a defense value of more than 10,000 is very rare, and the standard armor in the army is about 10,000, this is more than 30,000, which is really good!"

"Hey, are you okay?" Mo Luo got up from the ground and asked Xia Yu next to him at the top of his throat: "He can't be a 3-star monk, right?"

Xia Yu had already covered his ears, and at this time he was better than Mo Luo, so he leaned into Lu Qingyuan's ear and said, "In the explosion of the Zhang family, I released more than 50 No. 2 bombs in one go...... Well, this thing can deal with most 2-star beasts, right?"

"Except for a very few, otherwise it's all a spike!" Lu Qingyuan's expression was very excited, and he pulled Xia Yu to the side: "This thing is really made by this Mo Luo? Why do I think it's not reliable......

Haha, Moreau is indeed a little less master, but when it comes to the madness of research, Moreau is no one to lose.

The inspiration came, this guy can go three days without eating and be bored in the organ room!

Although there are times when I don't have to eat......

Xia Yu also didn't hide it from Lu Qingyuan: "The core of these two bombs is the 'black explosion powder' that detonated, which was researched by Mo Luo, and I made some efforts to the rest." So, I can't give you the secret recipe for 'Black Burst Powder', but these two bombs should be able to supply you some, how much do you need?"

"The more the merrier, but you don't seem to have a processing workshop to do it......" Lu Qingyuan said excitedly.

Mo Luo came over: "As long as there is Ouer to earn, Lao Tzu can rush to work without eating or drinking!"

"Don't talk nonsense, aren't you going to Bailu City with me?" Xia Yu glanced at him.

He turned to Lu Qingyuan again and said seriously: "Old Lu, you should know how terrible this kind of weapon of mass destruction that does not require perception and control is once it gets out of control. It's not that I don't trust you, but I believe you don't use it yourself, and you have to promise me that it will only be used on the beast battlefield. ”

"I understand, I'll be cautious. Xia Yu, I'm sorry that my identity is quite special, and it won't be good for you to know, but I promise you this. Lu Qingyuan's eyes became distant: "It's not as peaceful as Luo Tong's hundred years of peace, in some scattered shelters and marginal cities, it is difficult for many ordinary people to survive, and it is really difficult for people in these peaceful places to happen." ”

Xia Yu didn't ask any more, Lu Qingyuan didn't look like an ordinary person, but he didn't look like a big traitor.

The secret recipe of "Black Burst Powder" must not be revealed, so after discussing with Mo Luo, it was decided that Mo Luo would provide him with the finished product of "Black Burst Powder", and Xia Yu would be responsible for providing detailed mechanical drawings of these two bombs, and Lu Qingyuan would find someone to make it himself.

Because the two of them decided to go to Bailu City, Lu Qingyuan would arrange for someone to go there to pick up the goods in the future.

As for the price, although Lu Qingyuan has always behaved like a rich man, Xia Yu has no lion to open his mouth for Mo Luo, but after the two of them arrive in Bailu City, they must be short of money to set up a high-level organ room or even an organ laboratory, so they set a compromise price - 30,000 euros for 1 catty of black explosive powder.

Calculated down, 1 pound of black explosive powder is roughly enough for four No. 1 bombs, which is already the equivalent of a No. 2 bomb, and this price is definitely super discounted.

You must know that not counting the loss of labor and equipment, the price of raw materials for 1 catty of black blast powder is only more than 1200 euros, which is still not under the high price of a large number of saltpeter, otherwise it can definitely reach below 1000.

In other words, the profit of black fans should be 30 times, which can be regarded as super profiteering.

But this is normal, doing research is the most expensive, but if it is successful, it is also very profitable. Not to mention the huge profits of those pharmaceutical factories and health care products on the earth, Xiaoman said that the pharmacists in this world develop new drug powders with usable value, and the profits are more than 50 times, but the failure rate is too high.

In addition to black explosive fans, the technical licensing fee for the two bombs is 1 million euros at one time, which can be regarded as a friendship price.

For special reasons, neither Xia Yu nor Moro planned to apply for patents for the "Black Burst Powder" and these two bombs - the "Black Burst Powder" was absolutely impossible and would never want to be exposed, and whether the two organs that did not have a source array and did not use the source crystal could apply for it was a matter of two questions.

For these, Lu Qingyuan almost didn't hesitate and agreed to them all.

He took away some of the inventory in Mo Luo's hand, and then after checking the signal to the follow-up connection to Bailu City, he finally left with great ambition, and he no longer had the usual hippie smiling face.

"Hey Xia Yu, didn't you say that this gold lord is your life-saving brother, why did you still let me mix those useless ingredients in the 'Black Explosion Powder'?" As soon as Lu Qingyuan left, Mo Luo couldn't help but ask.

"This thing is not for his own use, it is the organization behind him!" Business belongs to business," Xia Yu shook his head: "Of course, the power of black fans to ordinary people is too great, and it must not be easily spread......"
