Tang Wen found Brother Li in the Outer City.
Brother Li immediately led Tang Wen to a warehouse and brought out several bags of saltpeter he had recently acquired.
"Good. Keep buying," Tang Wen said, tossing him another silver ingot.
Back home, under the curious gazes of the women, Tang Wen had the saltpeter brought inside. He prepared a large wooden basin, filled it with water, and then placed a smaller, water-filled round basin inside it.
SPLASH.
He picked up the bag of saltpeter and poured it into the wooden basin.
To the women's astonishment, a chilly mist formed around the large basin, and the water in the smaller basin gradually froze solid.
"What is this?"
"What's going on?"
"Brother, could it be... your ability has awakened?"
Tang Wen chuckled. "If this were my ability, it would be pretty useless."
He took out the finished block of ice and stored it in the cellar.
