Meng Yu's answer was simple and clear, and as for reasons, he didn't even bother to explain.
"This matter, it actually might be feasible..."
Some people felt that there was potential in this endeavor, so they started to persuade others. Some knives were too sharp to keep inside but could be beneficial when used outside to cut enemies. If Mirror Twelve could establish a base there, and continuously expand its influence, sending an unbroken stream of Spirit Stones and Cultivation Techniques back to the Immortal Sect, it would be immensely profitable.
Afterward, Meng Yu wouldn't have to take risks. He could make a variety of profits and earn Spirit Stones just by being a good transporter, allowing him to focus on cultivation. Under the guidance of a master, he could step by step achieve the Golden Core, Nascent Soul, and even Divinity Transformation.
