After a forest fire rescue accident, Shen Mingxi cast a vote in favor at the board meeting, firing her boyfriend Lu Zheng and making him bear full responsibility for a loss of 74 million yuan. Blacklisted by the industry and hitting walls everywhere when looking for a job, Lu Zheng saw through the truth of the relationship and resolutely broke up. He sold his real estate, and teamed up with old colleagues to start a business making drone safety control systems. Facing Huaging's multi-faceted suppression and technology plagiarism, Lu Zheng insisted on independent research and development, won the public test with strength, and collected evidence step by step to restore the truth of the forest fire accident. Huaging is heading toward decline, while Lu Zheng's Tianheng Technology is rising. He did not choose to forgive, but let the people who did wrong bear the corresponding consequences.
