《破茧2》李果杀害周昊和何静之是为了给宋教授报仇。
Heres a rewritten version of the provided text:
At the press conference, a recording surfaced of a conversation between Tang Dade, Zhou Hao, and He Jingzhi. In the recording, they confessed to conspiring to murder Professor Song. Tang Dade was devastated upon hearing this, especially upon discovering that his wife, Li Guo, was the mastermind behind it all. Years ago, they had jointly developed a patent with Professor Song, who had decided against publishing it. However, Zhou Hao knew the patent could bring them substantial wealth if published. Knowing Tang Dades affection for Li Guo, Zhou devised a plan to eliminate Professor Song, allowing Tang Dade to win Li Guos favor and profit from their research.
He Jingzhi overheard their plans. Initially reluctant, Tang Dade was swayed by his love for Li Guo and the lure of wealth. Unbeknownst to Tang Dade, Professor Song sacrificed himself to save them. If Tang Dade had known, he would never have agreed to Zhous plan. Tang Dade confessed to Li Guo, admitting his actions were driven by love and ambition. Li Guo entrusted a flash drive containing evidence to Tan Jingtian. While examining her belongings, Tan Jingtian noticed a syringe and deduced that Li Guo intended to inject bee venom into Tang Dade. He stopped her just in time, noticing scars from bee stings on her.
Tan Jingtian realized Li Guo was responsible for He Jingzhi and Zhou Haos deaths as revenge against Professor Song. Despite this, Tan Jingtian hesitated; he didnt want Li Guo to ruin her life seeking vengeance. Tang Dade also seemed to suspect this, confessing to killing He Jingzhi and Zhou Hao, though publicly revealing their bodies at the press conference seemed illogical. Li Guo was shocked that Tang Dade would take the blame for her. Intent on accepting her guilt, she aimed the bee venom syringe at herself, recounting her crimes. Her actions stemmed from hearing the damning recording of their conversation. Aware that Tang Dade was an accomplice, Li Guo reserved her utmost hatred for Zhou Hao and He Jingzhi.
During the investigation, evidence indicated Li Guo was with her uncle the day He Jingzhi died, supported by video calls with Tang Dade. This arrangement left little time for her to commit the crime. She admitted to separating the bee venom herself, which Tan Jingtian noted. Reluctantly, Tan Jingtian spoke the truth, aiming to prevent Li Guo from harming Tang Dade further. Though Tang Dade deserved punishment, he believed in legal justice.
《破茧2》精彩剧情介绍 第26集：真相大白，马里奥被逮捕
差亲自跟谭景天说明是他估计错了，但是谭景天相信自己的推断结果，他不管嫌疑人是谁。德找到了琴师的侄子，他交代是罗摩王子抢走了自己的du品，然后他还一路跟踪罗摩王子，发现他注射du品自杀这件事。现在根据罗摩王子自杀这件事，德分析他就是想要指向某个人，不然他不会费这么大的力气。现在根据现场的情况，唯一能够推断他要指向的人就是马里奥，因为他的手里紧握着马里奥的袖扣。
谭景天跟他们聊的情况，想到了在国内金灵的师傅曾经跟自己说过一个案例，是昆虫会受到du品的影响，让法医们根据昆虫的形态变化会产生误差。
差决定联系金灵但是金灵的电话没人接，德这次非常警觉，如果这几起案件都与马里奥有关，那金灵很有可能有危险。谭景天听到德这样说，非常紧张，要去找金灵。差立即安排德定位金灵的手机。金灵最后接了电话，原来她是在实验室忙着，所以接电话有些晚了。
谭景天告诉金灵自己会去接她下班，差决定和谭景天一同前往实验室。但是在下班前，马里奥以十五年前那具焦尸有线索了要带着金灵一起去素可泰府。金灵没有多想，放下手里的工作跟着马里奥离开了。

差带着谭景天和德先去了马里奥的家，发现了马里奥有虐待女性的倾向并询问他关于瓶子的问题。同时他们还发现了一本对女性很恶毒的书，里面有受害者女性的照片和金灵的照片。在马里奥的车后面，他们发现了信号屏蔽器。然而此时金灵却已经遭到了绑架。
差调动所有警力全城搜查金灵的下落，最终他们找到了金灵被马里奥挟持的地方并成功救出她。经过调查得知马里奥患有精神分裂症并误认为受害女性为被女巫附体，之后对案情的了解更是帮助他们最终侦破了案件。差得到了嘉奖并获得了真相。同时，在警察局的帮忙下解开了心结的谭景天重新回到正常生活并专注于工作上。
