Datang: I Use Technology to Improve People's Livelihood in Zhenguan

When Li Yan opened his eyes, he found that he had become the "adopted son" who was abused by a wealthy businessman. He was covered in injuries and had no memory. However, he awakened two golden fingers: mind reading, which allowed him to hear the voices of everyone within a three-foot radius; and the technology tree system, which could unlock cross-era technologies as long as it was for people's livelihood.
