"Heart of the Engine: Embedded Conqueror" is Chen Ruiqi's hard-core technology autobiography, telling his legendary journey from a boy in a northwest repair shop to a global automotive electronics leader. Because his father was destroyed by a defective ECU, he determined to conquer the embedded field. After accidentally binding the mysterious "Enlightenment System", he refined his technology in a German laboratory, debugged wire-controlled steering in the Nürburgring rainstorm, and developed anti-radiation algorithms in the ruins of Chernobyl. From breaking through chip blockade to creating an open source empire, in the end, in order to protect the purity of technology, he chose to format his memory and retreat to Qinghai Lake, condensing his life's wisdom into "Rich Paradigm" and gifting it to the industry. This is a romantic epic of code and steel, witnessing how hard-core engineers use persistence and humor to leverage the global technology landscape.
