According to what Su Xuan knew, the sisters later engaged in different professions: the elder sister ventured into the psychology field, while the younger sister entered the realm of science. As for where her career took her, Su Xuan was unaware. This time, however, the situation seemingly involved the Japanese, leading Su Xuan to suspect that the matter might relate to the power of technology. He had heard that many scientists had been researching a project named "War God," which was a joint initiative by several countries.
