The Shen Group, run by Shen Zhiyi, is deeply involved in an "energy monopoly conspiracy", and it is discovered that family members have been implanted with blood evil poison, which can only be cured by the secret medicine of the hidden sect "Taixu Pavilion". In order to get closer to Taixu Pavilion clues, she was forced to sign a three-month flash marriage agreement with the mysterious man Pei Jin, but she did not know that the other party was the Taixu Pavilion War Lord who was exiled due to internal fighting in the sect.
The day after the wedding, at the Shen's shareholder meeting, his second uncle Shen Yue (an undercover agent of the Blood Demon Palace) united with foreign enemies to launch an attack. Pei Jin, as an "ordinary bodyguard", subdued ten black-clad killers with his bare hands, showing his first talent. Shen Zhiyi was shocked when he discovered that Pei Jin's jade pendant exactly matched the "detoxification key" recorded in the ancient books of Taixu Pavilion.
As the killers of the Blood Demon Palace made repeated raids, Pei Jin's identity as a war master was gradually exposed: he smashed the body-protecting Qi of Xiantian masters with one punch in the underground boxing ring, and set up a "Nine Heavens Barrier" in the Shen's Building to resist poison attacks. Shen Zhiyi relied on his business skills to uncover the insiders of the Blood Demon Palace within the Shen Group and cut off their capital chain.
When the master of the Blood Fiend Palace personally led the "God-killing Formation" to encircle and suppress the enemy, Pei Jin broke through to the master realm to protect Shen Zhiyi, but he fell into a coma due to an old injury. Shen Zhiyi unexpectedly awakens the "Bingxin Jue" passed down by his family, and uses the secret medicine to awaken Pei Jin. The two work together to destroy the Blood Demon Palace's lair and expose Shen Yue's conspiracy.
When the three-month contract expired, Shen Zhiyi looked at Pei Jin's War Lord's token in his arms and asked with a smile: "Lord War Lord, do you want to renew the contract?" Pei Jin hugged her into his arms: "Not just renew the contract, it will be for life."
