Maria didn't come back, she was going to stay there to supervise the sunspots planting wheat, she was going to be Mulatu's helper, she had her own ideals.

Mulatu returned to the east and took Ammar with him, and there was no other way, because Ammar was too clingy and talked about the gas tank fence all day long, so Mulatu could only bring Ammar with him.

Amar has been to many countries and has rich experience in going abroad, and it was the first time he came to the East, he got off the plane, looked at everything very fresh, and after passing through customs, he saw a familiar figure standing at the pick-up gate.

"Mr. Qin, I'm so glad to see you." Amar stretched out his hand excitedly: "I came here this time to see those... Fence. ”

"Okay, of course it's no problem, did you bring the deposit?"

"As soon as we see it, we will pay the deposit immediately!" Amar said, "Mr. Qin, please take us over immediately!" ”

"Actually, I originally planned to only give away the drawings, but I heard that you came over, so I specially processed a finished product, go, I'll take you there."

Mulatu was a little embarrassed, this matter caused Qin trouble, it was all his own fault, he said that he would deliver the goods in Africa, but this Ammar just insisted on coming to the East to see.

Zhao Jiao followed behind Qin Feng gently, and when Qin Feng walked in front with Ammar, Zhao Jiao walked up to Mulatu: "Brother Mulatu, where is Sister Maria?" ”

"She didn't come."

"Really? It's a shame, and I really miss her. ”

"When the wheat over there is planted, it may come over."

"Well, I'm looking forward to it."

"Zhao, Qin isn't angry with me, is he?"

"How is that possible?" Zhao Jiao shook her head: "Brother Feng has been busy with your affairs recently." ”

"Really? When you say that, I am all the more ashamed. ”

A few people talked as they walked, walked outside, got into the fiery Santana, and headed northwest, soon into the mountains.

The mountains are undulating and layered, and it is autumn at this time, and the leaves are yellow and red, and they look very beautiful.

"It seems to be up ahead..."Ammar looked at the man-made structure on the top of the hill and said in surprise, "The Great Wall? ”

"That's right, it's the Great Wall, the wonder of the world." Qin Feng said, "I'll take you to the top to have a look." ”

Mulatu was a little confused, what was he doing on the Great Wall? Doesn't Ammar talk about gas canisters every day? Could it be that you are going to take a walk with this monkey rush first?

The car stopped at the foot of the mountain.

"Let's go, let's go up." Qin Feng said: "If you don't go to the Great Wall, you are not a hero, since you have come to our east, then you have to climb up and have a look, Mr. Ammar, let's go up and have a look." ”

Amar seemed to have forgotten about the gas tank fence, and climbed up with Qin Feng, Mulatu took a few steps behind and looked at Zhao Jiao: "Zhao, is this to sharpen his temperament first?" ”

"No, stuff is on it."

It dawned on Mulatu.

For people like Ammar, there must not be too many secrets exposed, whether it is a company, a family or a factory, nothing can be exposed, and Mulatu's father suffered a loss, and took this so-called brother to the house, and then people will come to the door if something happens.

This is the middle of nowhere, and Ammar, who came here for the first time, couldn't tell the difference between east and west, so it would be nice to show him here.

Ammar is active all year round and is in good health, and soon climbed up the Great Wall along a gap, looking at the ancient green bricks, looking at the battlement wall, and the beacon tower, Amar is really relaxed.

"This is a great miracle of humanity! Ancient people can create such great architecture, and we modern people are invincible! ”

"Standing here, I suddenly see hope."

Ammar was very emotional, and suddenly, he saw the beacon in front of him, as if something was out of place here.

One half of it is a huge cylindrical shape, which looks like a gas canister, and the other half is thinner, but at the end there is a thick flat plate, what is this?

Suddenly, Ammar thought of something, and his heart pounded violently. He took a big step and ran over.

Closer, closer, yes, it's what you need!

Mulatu's eyes widened, the fence made of gas canisters looked really spectacular!

"Genius, genius design!" Amar walked over and looked carefully at the device in front of him.

In front of it is an ordinary household gas canister, but the annular shield on the top of the gas tank has been removed, revealing a gas valve with a brass component installed on it, which is supposed to be a fuse.

Below is a twenty or thirty centimeter-thick tube, which should be filled with propellants, and the most distinctive thing is that at the end of this tube, a unique tail is welded.

The fence made of thin water pipes only welded four ordinary tail fins, but the one in front of me welded eight tail fins, and also welded a ring on the outside of the tail fin, which was as thick as the front gas tank.

What is this ring for?

Of course, it is used for stable launches.

The front is thick, the back is thin, if there is no welding ring, it will be crooked when plugged into the launch tube, with this, the front and back are the same thick, it is convenient to maintain stability, and there will be a higher accuracy when launched!

Genius, this ring is the most genius idea!

Ever since he met Qin Feng, Amar has been thinking about how to use a gas canister to make a fence, and after thinking about it for a long time, he also feels that it is unreliable, if the propellant behind it is as thick, then the weight of this thing will reach a terrible number, this is not a gas canister fence, it is almost up to Scud!

If the propellant behind it is finely made, how can it be stably launched? All he could think of was using a guide rail, and now when he saw this plan, he suddenly became enlightened, and he couldn't do it if he didn't admire it!

"Mr. Qin, can I take this sample away?"

"You can't get past customs." Qin Feng said: "Let's even give this sample to you when we ship it together." When the time comes, I will also attach detailed blueprints. ”

Muratu was a little curious, what detailed design drawings are needed for this? That's already detailed, right? With the brain of Ammar, a military genius, even if he doesn't trade with Qin Feng in the future, he can make it himself when he goes back.

Qin Feng smiled: "The gas tank is a very safe container, we have a lot of safety measures, so that it will not endanger the safety of people's lives and property, it is not easy for this thing to explode." ”

Since the other party has come all the way, Qin Feng has to give the other party some benefits, so that the other party can place an order, as for releasing his own pigeons? Of course not, we still have a unique job.
