Rainey was originally the second daughter of the Lloyd family, and she oversaw much of the family's business. Bringing her commercial strategies from her original world to this one would be like wielding a power that others couldn't match. With Rainey's abilities, expanding and strengthening the business should be no challenge.
Of course, relying on Rainey alone would be taxing, so Sebastian decided she needed a partner. He then thought of Stephanie.
Stephanie's family was also in business, and she had grown up surrounded by trade and negotiation, honing her business acumen. Moreover, as someone from this world, she would complement Rainey well, making them an ideal team.
Business might take time away from their cultivation, but he planned to compensate by providing them with extra cultivation resources. Both of them were currently in the Chimes Tower, so he would need to go there in person to bring them on board.
After taking down the Karcher family, he went directly to the tower. With Huntley and the core members of the Karcher family gone, the family was effectively destroyed.
Meanwhile, news of their destruction spread quickly, shocking everyone. The Karcher family had been a first-tier family, boasting three Lesser Deity Masters, and now they had been wiped out. It was a massacre on a scale unseen in decades.
The event sent waves of fear throughout society, giving rise to ominous rumors as people worried they might be next. The royal family soon took notice and ordered an investigation.
However, anyone who had seen Sebastian and his group in action was dead. Those who survived either hadn't seen anything or had been knocked out, leaving no witnesses to identify the culprits.
This world had no surveillance, and no clues were left behind at the scene. With no eyewitnesses, there was no way to track the perpetrators.
Nevertheless, the royal family's response helped ease fears somewhat. Since no similar incidents occurred following the Karcher family's fall, people eventually began to move past it.
Yet, the guild limited the supply, offering only ten pistols daily—five of each model. The weapons weren't available for direct purchase. They were only sold through auctions, with tickets awarded by lottery.
Only members with annual membership were eligible for the lottery. An annual membership offered a five percent discount on all guild items, but the cost was steep, priced at 100 spiritual stones.
With this strategy, the Supreme Merchants Guild gained over three thousand annual members within just three days. This meant that even before any handgun was sold, the guild had already earned hundreds of thousands of spiritual stones.
Plus, membership continued to soar, with more than a thousand new members joining daily.
