Chapter 513 Technical Difficulty

After seeing the drawings given by Yang Yi and the others, Macdonald just thought about it for a moment and then said in a deep voice: "It can be done."

Although they were all a group of well-informed people, everyone present couldn't help but smile after getting a positive answer from MacDonald.

Yang Yi hoped to settle the gold matter as soon as possible. It was already afternoon when he and Anton took Macdonald to Rome, but he still hoped to settle everything tonight, because the longer it takes, the harder it is to seize the gold. the less likely it is.

"But if there are requirements, you have to meet all my needs to be able to do it."

"Tell me what you need."

McDonald said calmly: "First you have to tell me how big an opening is needed."

"At least there's an opening that a small forklift or small loader can drive through."

McDonald thought for a moment, shook his head and said: "It may not meet your requirements, because the concrete of the wall is easy to solve, but the steel mesh inside the wall cannot be destroyed by blasting. That is to say, what you can see after blasting It’s a steel mesh that has lost its concrete, and you have to cut off the steel mesh to get in.”

Yang Yi said without hesitation: "How about gas welding and cutting?"

McDonald shook his head and said: "Of course, but it takes time. How much time do you have available?"

Yang Yi said helplessly: "I hope that the entire time from blasting to entry to evacuation can be compressed within ten minutes."

"That's the question," Macdonald laughed. "How long does it take just to cut the mesh with gas welding?"

After a slight blow to Yang Yi's confidence, McDonald said methodically: "So now my question is, can you confirm that the building structure type of the underground space is reinforced concrete? Couldn't it be another building structure type? Rome? It is a very old city. Although there are also new buildings, most of the buildings are ancient. For example, if the place to be blasted is a building before the 18th century, it can only be made of stones, although the stones are very hard. But this is similar to a brick-concrete structure in terms of building structure and can easily explode. If the building was built before 1950, it is unlikely that it will be a reinforced concrete structure."

Yang Yi said without hesitation: "That building was built in 1995. It has six floors on the ground and one underground floor. The basement was originally used as a parking lot. The parking lot is a large space, so I think the wall below is It was a later addition, but I’m sure those walls are very strong and very thick.”

McDonald frowned and said, "Did it be rebuilt later? This is troublesome because it is impossible to accurately determine the type of building structure."

After thinking for a moment, McDonald finally said: "Unless you can give me accurate information, I can't make a judgment without an on-site inspection."

"You can go in and have a look, because there is a nightclub there."

McDonald nodded and said: "Write down what I want, fifty pounds of C4, twenty pieces of PVC pipe with a diameter of 50 mm, a section of fifty centimeters, one end sealed with a plug, the length must be precise, and the diameter must be 50 mm. Monroe effect cone-shaped copper cover with a thickness of five millimeters, do you understand what I am talking about?"

Yang Yi nodded and said: "I understand, you want to make a simple hollow-charge armor-piercing projectile."

Macdonald smiled and said: "Strong double-sided tape for instant bonding, no glue required. There are also PVC pipes with a diameter of 30 mm and lengths of 40 cm, 50 cm and 60 cm, and 20 each for spare." , sealed at one end, requires twenty pounds of Octogen, at least a hundred remote-controlled detonators, five multi-line controllers, and two small single-line electronic remote controls, the smaller the better.”

Yang Yi just has a good memory, but he naturally doesn't know what things he has never been exposed to are. For example, he doesn't know what Octokin is.

"What is Octogen?"

Without McDonald's need to answer, Brian said in a deep voice: "A kind of fraud. It is currently the most powerful single substance fraud. It is powerful but has a low output. It is mainly used in the warhead of missiles."

McDonald nodded and said: "Yes, but Octokin is very difficult to find. If you really can't find it, just get more C4."

Brian frowned and said, "Twenty pounds of Octogen, isn't it too much?"

McDonald shrugged and said: "It's not necessary to use them all. It's always good to prepare more."

Yang Yi immediately said: "Okay, I'll have someone prepare these things."

McDonald knocked his head and said solemnly: "The wall is very thick, but I don't know the construction type of the wall, so you have to be prepared. If it is really a reinforced concrete wall..."

After pondering for a moment, McDonald nodded and said: "I will try my best to use the shearing effect of blasting to directly destroy the steel structure. I will not let you use gas welding or liquid nitrogen freezing to break the steel before entering."

Brian frowned and said, "Can blasting also produce a shearing effect?"

McDonald nodded and said: "Of course, it's just a technique. It can be done by using the slight difference in detonation time. It's just that it's easy to say but difficult to do. I haven't done it for a long time, so I'm not completely sure. Destroy the steel mesh, so you'd better bring something like gas welding or liquid nitrogen bottles."

While MacDonald and MacDonald were talking about blasting techniques, Yang Yi had already sent what MacDonald requested to the cleaners and got a reply immediately.

Yang Yi said to McDonald: "Everything you want is fine. It will be ready before eight o'clock tonight."

McDonald said with a hint of surprise: "You guys are quite efficient. It's easy to find copper, but it's not easy to process a conical cover that meets the accuracy requirements. Yes, I thought you would have to spend some time to find it." .”

Yang Yi didn't want McDonald to know the existence of the cleaners, nor did he want him to know that the man in gray was going to be bombed, so he just smiled and didn't answer.

McDonald exhaled and said: "Okay, it's now half past four in the afternoon. If the things can be delivered at eight o'clock, I can do what I need before twelve o'clock in the evening. So when can I Can we go to the site and check it out?”

Yang Yi looked at his watch and said: "The nightclub opens at seven o'clock, so you have time to go in and check."

McDonald stroked his stylish beard thoughtfully and said, "It's rare for me to go into a nightclub at my age."

Yang Yi pointed towards Kate and said with a smile: "It doesn't matter, she can make you look at least twenty years younger, and by the way, it can also prevent others from recognizing your true face."

McDonald smiled, and then he said happily: "You don't look like a mercenary group, or maybe I have fallen behind. Are the mercenary groups nowadays so versatile?"

If Yang Yi wanted MacDonald to know about the water organization, he would have told him earlier.

So Yang Yi just smiled and said: "Multiple skills and multiple paths, the mercenary group must develop towards diversification to survive. There is no way, who made us catch up with this era."
