"Āijí Fāngkuài" is an original song featuring Luo Tianyi and YANHE. The song seems to be about ancient Egypt and despite its ancient tone, it rather has questioning and forgotten themes, mentioning "The Nile River past through the Sahara that writes the endless myth." (尼罗河穿过撒哈拉 写着永不完结的神话) and “The difference of love and hate with life and death that questions the sand storm of the millenniums." (那些爱恨生死的落差 问这千年的风沙) This song exceeded 100,000 views on bilibili.
