Crossing the gate, Sean heard a loud bang, as if heavy metal components were colliding violently. In addition, there were various sounds such as gears, engine buzzing, and flame burning, just like a noisy band.

Judging from the sound, there is a whole factory hidden at the bottom of this base, and the owner of the factory is undoubtedly Zhuanghara Ei.

The deeper Sean went, the more surprised the girl with horns in her heart. He had been to Hongxing Base for a while and naturally checked the three-dimensional map of the base, but the map only showed the part above the long passage. As for the parts below, they were listed as top secret, and even with Sean's permission, they could not see it.

Now it seems that the weight of this top secret is really not only about this base, but also about the deep secrets of the Red Apricot Team and even the Silver Knights.

But now is not the time to explore the secrets. There are countless secrets in the Milky Way. If you explore them one by one, it would not be enough to live Sean for another 800 years. So now he only has one thing to do...

"Today, I'll demonstrate the maintenance method of the [Sky No. 3] engine."

Zhuang Yuanying took Sean to a flawless processing workshop, and said with a stern look at a spaceship engine placed in the middle.

"[Sky III] is a general-purpose engine designed and finalized by Beihe Industry seven hundred years ago. It can be assembled in a variety of spacecraft very conveniently. Although there are certain defects in design, it is cheap, has strong production capacity, and is sufficient for use. Therefore, in the next seven hundred years, even though it has undergone multiple versions, [Sky III] has always been the most common spacecraft engine in the Qianxing system."

Sean nodded vigorously. He had gradually mastered these common senses through various channels during this period. However, the same knowledge, which was naturally more credible, was spoken by Zhuang Yuanying, a senior mechanic.

"More than half of the various spacecraft of the Silver Knights are loaded with similar styles [Sky III], so mastering this model of engine is also a compulsory course for every mechanic in the Silver Knights."

As Zhuang Yuanying said, she walked up to the workshop processing table, controlled several robotic arms, and began to remove the engine that was more than one person tall in front of her.

The one sent to the workshop obviously experienced very rough use and was not properly maintained. At this time, the whole body was charred, as if it was burned by fire, and black smoke continued to emerge from the cracked cracks; half of the turbine fan blades at the injection port were broken and bent.

After disassembling it, the internal situation was terrible.

From Sean's perspective, this thing has little rescue value. Instead of trying to repair and repair it, it is better to contact the manufacturer to change it to a new one. Anyway, this [Sky III] is the most popular civilian style in the Qianxing system. Not only is the low price, but the access channels are also very wide. Even if there is a problem of material embargo in the abandoned areas, it is difficult to [Sky III].

But looking at Zhuang Yuanying's focused and even pious expression, Sean knew that for this girl mechanic, the problem of mechanics was never a financial calculation. Even if it was not for the demonstration of technology, she would not let an engine with emergency repair value be scrapped.

With the dance of the robotic arm, this [Sky No. 3] was dismantled into countless tiny components. While explaining the structural principles of the engine softly, Zhuang Yuanying classified the dismantled components. Among them, waste products that cannot be repaired are classified into one category, and those that can be continued to be used after processing are placed into one category, and those that are intact are the last category.

In the girl's soft voice, the pile of components that symbolize waste are getting higher and higher, which makes Sean wonder: Zhuang Yuanying abandoned at least one-third of the components, how would she plan to repair them next? Even if there is sufficient component reserve in this underground base and can replace all the waste, the entire engine is dismantled like this, and reinstalling it will inevitably affect the overall performance.

"Next, it's the core of today's course. For severely damaged engines, you cannot repair them according to the conventional ideas..." Zhuang Yuanying said, pausing his work a little and beginning to carefully prepare explanations, but the girl's eyes were still focused on the workbench, and she didn't even look at Sean.

Sean didn't care. With Zhuang Yuanying's shy personality, she might be able to speak smoothly. Compared to Zhuang Yuanying's attention, he cared more about how the other party planned to repair the engine that was dismantled into scrap.

"The universality of [Sky III] has always been well-known, and this universality does not only mean that it can be installed smoothly into many different models of spacecraft. More importantly, [Sky III] is a prototype of many similar engines. Therefore, under certain conditions, [Sky III] can be converted into other models of engines."

When Sean heard this, he couldn't help but be stunned: Is this a joke?! The engine is not an assembled toy. Whether it is manufacturing or maintenance, it requires an absolutely precise environment. Can it be transformed temporarily?

However, as Zhuang Yuanying's processing steps continued to advance, Sean was even more surprised to find that the dilapidated [Sky No. 3] was actually turning into a brand new shape bit by bit.

The originally slightly complicated turbo fan blades were cut and removed as a whole, and a set of grids made of special steel plates made of shells were replaced; the core reaction chamber was tied up by one third, which reduced the engine efficiency, but also allowed the engine to maintain normal operation; the charred and cracked shell was simply welded and filled and installed back, which looked a bit crumbling, but considering that the overall performance of the engine has declined, the shell does not need to provide such strong fixation and heat dissipation functions...

After a series of operations, [Sky No. 3] has been beyond recognition, but it has a new vitality. After all, Sean has accumulated considerable knowledge. After observing for a while, he confirmed that this engine that was carefully repaired by Zhuang Yuanying was castrated and modified based on the lowest-equipped [Sky No. 3] type in the Sky Series, and in theory it can operate normally.

Although as a low-end model, the performance of [Sky Wilderness] is almost half castrated compared to the original version, but there is still performance at all - before repair, [Sky Wilderness 3] is just a waste waiting to be scrapped.

At this point, Sean was only amazed. Zhuang Yuanying's skills were not very shocking, and she was even deliberately restraining her level. She did not use her own strange power and unique machine gun throughout the whole process. All operations were made with the most simple and unpretentious techniques, and even the movements were slow.

It seems to be saying: As long as you memorize this process, anyone can do the same thing.
