"I'll tell you about mine first!"

Yu Yang looked around: "There is information about the delivery of Brila Valley in the news I inquired about before, I think we can buy it or stop a car and follow the car in, but if there is a leak, we may ......"

John shook his head: "I've thought of this way, but I think it's too dangerous, if it's discovered, we may not even enter the door, we need to fight, we don't even know the fire equipment inside, we can't rush in!" ”

Yu Yang nodded: "I also know, but in the current situation, I can't think of a good way, this Brilla guard is too strict, this kind of terrain, it is not possible to get in!" ”

John nodded: "I thought of a way, but I need some materials, I can simply make a catapult equipment, we can catapult it directly, but this catapult equipment needs some small hydraulic presses, and it needs to be professionally trained, which of you has received professional catapult training, and falling from about three meters in the air can ensure that your body is not harmed?" ”

Wang Hao, Lao Fu and Lao Zhao looked at each other and shook their heads at each other, at that time, they had no training in this area, basically they didn't know about these equipment, Yu Yang had only seen it when he participated in the all-army competition before, and he had tried it a few times.

"Then Yu Yang and I will touch it in first, find out the state inside first, and then make the following battle plan when the time comes! But I need some equipment to buy some catapult machines, and I'll write it out later, and you guys will buy it separately! ”

"No problem!"

Half an hour later, John handed the written things to Yu Yang, Yu Yang led people to leave quickly, and began to purchase items, now Yu Yang is a little nostalgic for a certain treasure in China, what John wants, if in China, Yu Yang and others don't need to go out at all, basically they can buy it all without leaving home.

But in Colombia, you can only go to one store to find it, buy a catapult board in the east, buy a screw in the west, and although the city of McCaw is not small, there are not many things in the small grocery store, Yu Yang has been looking for a long time and has not found it, and finally can only go to some big shopping malls in the city center, and it took more than a day to get all the things John needs.

I have to admit that Americans have very strong hands-on ability, and the education they received since childhood is different, so in the use of tools, John can be said to be very proficient, after buying items, John has used a day later, he has already made a catapult, in fact, the principle is very simple, that is, use a hydraulic transfer rod to throw people out, just like a trebuchet, but if you want to accurately eject, you need to test several times.

"Find a place where no one is and try it first, Yu Yang, how much do you weigh?"

"One hundred and sixty pounds, and if you add equipment, it will take about two hundred and ten pounds!"

John nodded, asked Wang Hao to buy a more than two hundred pounds to carry on his back, found a place outside the city where there was no one, put the object on it, and then pressed the launch button.

The object of more than two hundred catties was thrown out for a distance, but soon the opportunity fell directly to the ground, John shook his head: "No, the height is not enough, the wall we have to cross is about three meters, and this distance is only more than one meter!" This hydraulic rod doesn't work, I need to change it, and the angle can't work, I need to recalculate the formula! ”

As he spoke, John began to calculate, holding a piece of paper in his hand and starting to calculate the formula, finally nodded, took out his toolbox, and began to modify.

After about half an hour, John made the thing good again, and then threw it again, but the result was still a little dissatisfied, no way, the most critical hydraulic rod had some problems, it could not meet the requirements, and the power of the ejection was not enough, so it could only fail.

"Go back first, I'll figure out a way, see if I can get it!"

Back at the hotel, Yu Yang looked at John, who was enchanted, took out a cloak and put it on his body, and walked out of the room, two hours later, Yu Yang returned to the hotel, John was still studying his catapult device.

At night, when everyone is sleeping, only John is still researching, John is not going to be a scientist, Yu Yang feels a little sorry for him, this spirit, if he goes to be a scientist, John may now be able to see him in some science and technology magazines in the United States, a scientific bull who has been delayed by being a soldier, maybe an inventor!

Yu Yang got up at about two o'clock in the middle of the night, and when he left the hotel and walked more than a kilometer, he saw two people standing sneakily on the side of the road.

Yu Yang walked over quickly, and the two of them opened the car next to them, and then revealed the contents inside, and then smiled at Yu Yang and stretched out his hand, signaling to give money.

Yu Yang looked at the equipment, and one of them looked at Yu Yang with some impatience: "These things are all things from the army, and the quality is guaranteed!" ”

"Okay, you guys in detail!" After Yu Yang finished speaking, he took out some US dollars and handed it to these two people, the two of them weighed it, nodded, and gave Yu Yang a thumbs up: "Dude, what do you need in McCaw in the future, just come to us Mai Brothers, as long as you can think of it, there is nothing that our Mai Brothers can't get!" ”

"OK, I'll be looking for you next time!" Yu Yang lifted the five bags, straddled them directly on his body, and walked towards the hotel with the bags, the two Mai brothers looked at Yu Yang carrying five bags, and couldn't help but look at each other, this thing adds up to nearly one hundred and fifty or sixty pounds, this guy can be lifted up at once, and the strength is a little too terrifying, fortunately they are serious businessmen and do not sell fakes!

When Yu Yang returned to the hotel, John was still studying, Yu Yang knocked lightly on the door, and John didn't raise his head: "What's the matter, it's going to be fine soon, I've already figured out a way, I just need to add a teleportation device here, and a pressure spring, I think there shouldn't be any problem!" ”

John said as he continued to work, Yu Yang patted him on the shoulder: "John, this is the catapult equipment you want, I've already found someone to buy it, you don't have to stay up late to do it, let's find a place to test it tomorrow, and you can use it at night!" ”

After Yu Yang finished speaking, he put the backpack on his shoulder beside John, John opened it, his eyes lit up, and he immediately took out a catapult to dismantle it, and then looked at Yu Yang excitedly: "Yu, how can you do this?" How can you do that? I'm going to figure it out in a minute! ”

ps: It came out of the hotel code
