"Director, your express parcel."

Hu Jianguo took a look at the package with a little wonder. It was very small, with a length and width of only about 10 cm.

So small, what is this?

He remembered that he hadn't bought anything recently, and guessed in his heart, could it be something sent by a certain brother unit?

So he waved, "Xiao Li, put it on my desk."

He didn't care about this small package. Hu Jianguo sat on the sofa in the reception area and continued to talk with Liang Wencheng.

"Old guy, what are you going to do next?"

Liang Wencheng sighed softly again, "If you don't have much hope here, you can only pin your hope on imports, hoping to import some of the single crystal high-temperature alloys we need."

The current turbofan x uses the best domestic high-temperature alloy, but after several verification and test drives, there will always be a series of problems with the turbine blades.

Such as ablation on the surface of the blade, or cracks in the blade, etc.

How long has it been? It's just a test drive. In this way, there is no service life at all.

Turbine blades are key parts of high temperatures and also life parts. They must meet the service life of at least 1,000 hours. In foreign countries, they are often 5,000 hours or even 8,000 hours.

Hu Jianguo apologized, "We can't help for the time being. The development of domestic single crystal high-temperature alloys takes time. I suggest that we should focus on foreign countries and strive to import some single crystal high-temperature alloys first."

Liang Wencheng said: "It seems that this is the only way to go. I hope to import some single crystal high-temperature alloys."

He thought so, first import part, use it first, and take a look at it step by step.

Otherwise, what else can I do?

The pre-turbine temperature of the turbofan x engine should be further increased, otherwise the thrust-weight ratio cannot be increased. The service life of the turbine blades should also be improved, at least 500 hours of use, and it would be better if it could be used for 1,000 hours.

After chatting for a while, Liang Wencheng stood up and said goodbye. Since his hope was shattered, he would go back as soon as possible and devote himself to his work again. His time is very precious. He wished he could use it for two days, and he wished he could solve all the technical problems of turbofan x and enter the mass production stage as soon as possible.

With apologies, Hu Jianguo sent away his old friend, sat on an office chair, and picked up the small package on his desk.

"Hey, it was mailed by Global Shipping Group. What would it be inside?"

Hu Jianguo was a little puzzled. He remembered that he had no intersection with Global Shipping Group at all, so how could the other party send a package?

Take out a paper cutter from the drawer, Hu Jianguo carefully opened the package and found something wrapped in plastic film, and then there was a small printed note.

There are only a few sentences on the small note, meaning that this piece of metal is extraordinary. Please ask the Special Metal Materials Research Institute to carry out a series of verification work, including its density, melting point, hardness, tensile strength, etc.

Is the piece of metal wrapped in the plastic film? Hu Jianguo took off all the plastic film and saw this small piece of metal.

He is an authority in metal materials. He can tell at a glance that it is a piece of metal, not a stone. He also found that the density of this piece of metal is very small and looks very light.

After looking at it with a magnifying glass, Hu Jianguo realized that the metal was unusual, so he immediately picked it up and walked towards the laboratory.

North Pacific.

The Overlord returned here and took a good rest in his cave for a few hours. He felt hungry, so he set out with a giant spear and headed to the huge cave six or seventy nautical miles away.

It still held hope, why did several giant octopuses in the giant cave disappear? Will they return to the giant cave again?

After a while, the Overlord arrived at the entrance of the giant cave and swam in without hesitation.

The depth gradually increased, and no shadow of the giant octopus was found until more than 5,000 meters. Then, it went down to the bottom of the giant cave, with a depth of about 6,500 meters.

It's empty, and there are no giant octopus.

Even none of them.

The hope was shattered, and the Overlord was a little unhappy. He looked at the gray-black "stones" at the bottom of the cave, and then slowly swam out of the cave.

I feel like I'm getting hungry.

Forget it, there is no giant octopus, go find something else to fill your stomach.

The King reached a distance of one or two hundred meters below the water surface and began to look for large fish to fill his stomach.

The big fish with hundreds of kilograms were not disliked. Although it might not be enough to stuff the teeth. Following the principle that mosquitoes are small, the overlord ate one bite and ate more than a dozen big fish with hundreds of kilograms.

These include a bluefin tuna of five or six hundred kilograms. Such a big fish is in some high-end restaurants, and it is a sky-high price.

The Bawang finished it in one bite, and it seemed that there was no time to experience the taste.

There was a big whale in front of me, squirting water on the sea. The overlord rushed over and treated it as food.

The King of Kings ate hundreds of big fish, including a big whale, and finally got half full.

Without a giant octopus of thousands of tons per person, the overlord's predation seems a little more troublesome and takes time. It took more than an hour to eat five or six points.

Forget it, I'd better look for it. I'd like to find out if there are any trenches nearby. The owner said that the giant octopus in the giant cave might have slipped away and might have hidden in a nearby trench.

The Overlord swam under the sea, and the Overlord swam around the underwater plains at a depth of more than 3,000 meters, and the distance gradually became farther and farther.

After swimming about two hundred nautical miles, the Overlord found that the terrain had finally changed, no longer flat, but ups and downs.

After swimming forward for a few miles, the terrain at the bottom of the sea tilted, slowly facing upward, with a certain slope.

This is a submarine mountain range, very long and average in height, just two or three hundred meters higher than the underwater plain.

After climbing over this mountain range, the Overlord found that the terrain was tilting downward and the angle became larger and larger.

After a while, the Overlord stopped.

At this moment, it felt a surprise in its heart. A big trench was bottomless and stretched across its face. It had no idea how long, wide or deep it was.

Because it completely exceeded the super perception range of the Overlord's 500 meters, after stopping for a while, the Overlord swam into this deep trench.

The depth gradually increased, and the Overlord swam to a depth of five or six thousand meters, but still had no reaching the bottom.

The Overlord was not ready to continue to go deeper, but instead swam at this depth, with super perception open, hoping to find that giant octopus.

After swimming for a few miles, the Overlord stopped again, and a huge figure appeared within its super perception range.
