Chinese authorities have executed a man convicted of poisoning and killing a billionaire gaming executive connected to Netflix’s “3 Body Problem” series, according to local media reports published Tuesday.

The man, Xu Yao, was found guilty of murdering Lin Qi, founder of Shanghai-based Yoozoo Games. The company holds adaptation rights to the popular science-fiction trilogy “The Three-Body Problem.”

Written by Liu Cixin, the trilogy has gained global recognition, translated into more than 40 languages and adapted into various TV and gaming productions, including Netflix’s 2024 series.

Xu, a former senior executive at a Yoozoo subsidiary, carried out the poisoning in 2020 following a workplace dispute. Reports say he became resentful after being sidelined by Lin, shortly after helping secure the Netflix deal.

He was convicted in 2024 and executed on May 21, according to Chinese business outlet Yicai Global and other media.

Yoozoo Games confirmed the development in a statement posted on Weibo, saying the case has now concluded and justice has been served.

“We are deeply grateful that justice has prevailed,” the company said.

Authorities and the Shanghai High People’s Court have not issued further comments.

Local reports indicate Xu spent large sums of money to obtain highly toxic substances online, including alpha-amanitin — a deadly toxin found in certain mushrooms. He reportedly mixed the poison into probiotic supplements and also placed it in coffee capsules, drinking water, and whiskey, which he shared with Lin and other employees.

Lin fell seriously ill in December 2020 and died days later at the age of 39. Several other employees were also affected but later recovered.

The “Three-Body Problem” series remains widely popular both in China and internationally. Its author, Liu Cixin, became the first Chinese writer to win the prestigious Hugo Award, and the trilogy has helped boost China’s science fiction industry across multiple platforms.
