He was the elder brother of Tan Tingkai (the concubine of Tan Zhonglin) and took good care of his younger brother. Tan Tingkai later became his right-hand man. Tan Yuanchen has a clear memory of the materials (technical documents, management documents, etc.) And historical events before time travel. He uses these prophetic conditions and his own scientific and technological knowledge to lead China to become a superpower.
