Over there, there was a large tree, the only point of contact between him and Wu Tiejun.
At this moment, the hollow of the tree was almost filled with Wu Tiejun's call for aid letters.
Feng Yin didn't read them, he could basically guess what the letters said. There was little point in reading them or not. In a flash of thought, he asked Feng Ying to take the Cat Emperor and the others back to the yard. He had to go see Wu Tiejun.
Feng Yin planned to manufacture a batch of medicine, but the medicines he had on him were all too high-grade. It wasn't that Feng Yin was unwilling to use them, but using these spiritual materials to make medicine would cause ordinary people, regular soldiers, and martial artists with weaker powers to explode on the spot from just consuming one pill.
In addition, the medical concoction Feng Yin wanted to make didn't really require a specific efficacy, he just needed a large amount of medical materials, and lower-grade ones would suffice.
