The Overlord stays there!

After a while, I came to my senses and looked at the exposed metal in disbelief. It could not figure out how this cave was a metal ground.

If you don't understand, ask the master.

The overlord said: "Master, please take a look at the situation here. What a great cave, why is it from the metal ground?"

What!

Liu Yong's eyes were wide open, and he couldn't believe it was true. He gradually accepted the facts after a long time. There was indeed a gray-black metal in this temporary cave of the Overlord.

Through a third-party perspective, Liu Yong saw something.

At the entrance of the cave, Bawang cleaned a small piece of land, with an area of ​​about a few square meters, about two or thirty centimeters thick, revealing the metal below.

It was a whole piece of gray-black metal, very flat and smooth, and looked so gratifying.

I searched for it without any effort to find it!

After searching for so long, the Overlord even searched the surrounding two or three nautical miles, but found nowhere to be discovered. The gray-black metal actually appeared here.

Excited!

This metal is excellent and may be a product of alien civilization. Liu Yong hopes that the more it is, the better.

They are of great use and can be widely used in many industries. In addition, each kilogram can be sold for 20,000 yuan.

Excited, Liu Yong slowly calmed down and thought in his mind, how could there be such metal in the temporary cave of the Overlord?

The hole of this hole is almost rectangular. Is it formed naturally or artificial?

Now that gray-ferrous metal has been discovered, Liu Yong believes that this is an artificial cave.

"Battle, clean the entrance of the cave and clean the soil."

"Okay, no problem." The Overlord agreed immediately and cleaned it up with its giant spear.

The giant spear is relatively large and the efficiency of cleaning is relatively fast. However, during the cleaning process, the sea water, which was originally extremely clear, suddenly became turbid.

The turbid sea water affected Liu Yong's vision to a certain extent, but he could still see some general situations.

The soil at the entrance of the cave is solidified and not muddy, so it is much easier to clean up.

The Overlord first cleaned up with a giant spear, and then cleaned it with his claws.

The snapping turtle is originally a master of digging holes. The overlord's claws are huge and it is very convenient to clean them up.

One hour later.

The entrance of the cave was basically cleaned up, and all the hard layer of soil covered with solid slabs was cleaned up, just like an egg was peeled from an egg shell.

Finally revealed its true face!

It is actually all metal, all made of gray-ferrous metal, showing the luster of metal.

Oh my God!

This is not a natural cave at all.

Instead, it is an artificial cave composed of gray-black metal!

etc!

It may not be a cave at all, but something else...

As soon as this thought popped up in Liu Yong's mind, he was shocked and was so excited that he couldn't control it.

If this speculation is true, it would be too shocking!

Taking a few deep breaths and trying to calm your mood, Liu Yong ordered: "Battle, your task is to clean up this cave in the next few days and let it reveal its true colors."

"Okay, master."

The Overlord now has time and doesn’t have to spend a lot of time on prey everywhere. It can take more than ten hours to clean up every day.

Liu Yong's plan is very simple. He cleaned up the cave and even the surrounding area, so that the original appearance will be revealed.

…………………

A famous aviation engine manufacturer.

On the test stand in the test workshop, after more than ten days and a total of 300 hours of long-term assessment and test drive, this turbofan x finally stopped working.

The director of the test workshop looked excited and walked to Liang Wencheng, stood attentively, and reported loudly: "Comrade, the chief designer of the report, the turbofan x No. 005 machine successfully completed the 300-hour long-lasting test drive, and all data indicators were qualified!"

As soon as the voice fell, there was warm applause on the spot. It was not easy!

The people participating in the test run all thought it was like a dream. The test run was too smooth. All the problems that everyone was worried about, such as the turbine temperature being too high, insufficient thrust, and excessive vibration, did not appear.

Liang Wencheng was also much more relieved, and a look of joy appeared on his face. He was confident in the design of the turbofan x, which was completely at the design level of the fourth-generation aircraft engine.

There were always various problems before. From the project establishment to the present, only a few units have been produced in several years. The fundamental reason is not the design, nor the manufacturing process, but the materials.

Especially the high-temperature materials in the turbine part always have problems. Now, this problem no longer exists, which can be seen from this test drive.

Liang Wencheng said loudly: "The 300-hour long-lasting assessment test truck was successfully completed, and the engine was sent to the assembly workshop for disassembly and inspection of each part."

This engine is taken off the test drive table, loaded, and sent to the main assembly workshop for disassembly and inspection.

The next day.

Liang Wencheng and a large group of people arrived at the assembly workshop. The engine had been dismantled and was now in the state of parts. Inspection personnel and technicians were conducting inspections of various parts.

Liang Wencheng walked to the turbine blades and looked at them carefully. Gradually, his face showed a look of satisfaction.

After 300 hours of test run, the leaves still remained unchanged in color, still the gray-black as before, without blueness, ablation, etc., let alone microcracks and so on.

"I can't believe it, this is the blade after 300 hours of test drive."

"It's great. It seems that the material problem we are facing has been completely solved."

“…”

The people around him seemed happier than the other, whether they were backbone technicians or senior managers.

This engine successfully passed the 300-hour long-term assessment test drive, and Liang Wencheng and the others had to do more things.

When changing the materials of some parts to gray-ferrous metal materials, the proportion should be more than 20%.

Liang Wencheng is very much looking forward to what will the performance of the turbofan x more than 20% of the parts will be changed to gray-ferrous metal material and how much can it be improved.

There are several points that are beyond doubt. One is the increase in the thrust-to-weight ratio of the engine, and the other is the increase in the service life of the engine.

…………………

For several days, the Overlord basically kept cleaning the cave except eating and sleeping.

Its sharp claws are very good cleaning tools. The huge cave, including a large area at the entrance of the cave, has been cleaned up, and the soil layer covered on the surface has been cleaned up, revealing its true appearance.
