Qinghuai Ancient Architecture Museum is going to be gone! Su Yanci clutched the mortise and tenon chisel handed down from her grandfather and only raised her eyes in the face of the real estate developer's ridicule: "If you dare to demolish it, I will restore it for you to see." She squatted under a century-old beam and knocked, but she didn't know that the man with the camera behind her had already been moved - in Lu Shiyan's lens, there was not only the shimmer of the wood pieces, but also the girl's focused profile. When rumors of fakes spread, she took out her ancestral ink fountain to draw out the truth; when the ancient building was on the verge of collapse, she shocked everyone with her secret tenoning skills.
