"What kind of business?" Ying Chenlin looked at Shen Xingtang.

"A business that turns trash into treasure," Shen Xingtang replied.

The technology of mechas was constantly evolving, especially for basic materials like parts. New models were released almost every year, and for those with high replacement rates, it was normal to have two or three new models each year. Typically, mecha teams in the mecha Alliance would frequently replace parts to maintain their mecha hardware level.

Among the parts in A3 warehouse, some were already destined to be phased out. Once new parts were added to the inventory, the old ones could only be sold at a discounted price to recover some funds.

However, things were different now. The parts that Ying Chenlin had re-polished had performance levels almost equivalent to the highly-priced parts in the market. In such a case, why would they go and buy those parts at a higher cost...?

"Chenlin, you may think that using mental power for polishing is a small matter," Shen Xingtang presented the so-called scrap parts and explained, "These parts with such performance levels are priced at around 100,000 to 150,000 credits in the market."

Ying Chenlin had foreseen it, but hearing Shen Xingtang say it out loud, he was surprised. "Higher than I expected."

"Yes, but that's not the main point," Shen Xingtang said with a grin, "For example, this A-GZ1456. Its current market price is around 30,000 credits each, and you alone have increased its profit margin by almost 100,000 credits. As for those so-called scrap parts of yours, you can sell them within the alliance for at least 130,000 credits each."

"Just now, that Mr. Xu, who called, wanted to sell us parts with 3% lower precision than your scrap parts, and he dared to ask for 100,000 credits. He even intended to increase the price. Moreover, these are A-Class parts, not competition-grade parts. There are many non-professional A-Class mecha mechanics in the Star Alliance, and they also need this type of parts."

Shen Xingtang didn't intend to keep anything from Ying Chenlin and explained all the pros and cons. "So, do you still think mental power polishing is a small matter? Your skills are not possessed by many mechanics in the alliance."

Jiang Simiao had been worried about the KID supplier issue before, but now, after hearing Shen Xingtang's explanation, he also understood, "So you turned down Mr. Xu."

The warehouse fell silent for a moment. After a while, Ying Chenlin spoke, "Do you plan to sell these scrap parts?"

"Sis doesn't hide anything from you. I'm a businesswoman, so I want to propose a collaboration with you," Shen Xingtang laid out the benefits and disadvantages. She wasn't sure about Ying Chenlin's background, but honesty was the foundation of any collaboration. She said directly, "Since it's a collaboration, these won't be part of the KID mechanic contract. I can sign a profit-sharing agreement with you. Everything can be discussed."

Looking at Shen Xingtang's earnest expression, Ying Chenlin considered that in his previous life, he had dealt with part polishing in a relatively mature technological era. Later, as the technology for mecha parts improved, the difference in commission for polishing was almost negligible. Moreover, he had spent a long time in the base, where materials were provided by KID, so he didn't really know much about the ten-year transformation of the parts market.

Polishing parts was just a habit he had before repairing mechas.

"Can I make a request?" Ying Chenlin asked.
