In Episode 39, Lai Luo Zhi has been plotting from the start, showing no fear even when the powerful Empress Dowager intervenes. Many officials in the court look down on him, but Lai Luo Zhi instructs Shen Du to “invite” these dissenters back.However, Shen Du has his own agenda; he doesn’t intend to genuinely align with Lai Luo Zhi but quietly brings his own forces closer. The entire scene, including timing and characters, has been carefully staged by Lai Luo Zhi, with Lai Luo Fu also mingling in, planning to turn against the Empress Dowager.

At a critical moment, Shen Du swiftly stops Lai Luo Fu's assassination attempt. They fight, but Lai Luo Fu is no match for Shen Du and soon lies severely injured on the ground. Seeing this, Lai Luo Zhi takes a decisive step and ends Lai Luo Fu's life, confidently proclaiming that their grand plan will succeed.

Lai Luo Zhi mistakenly believes he has many subordinates, unaware that they’ve all been dealt with by General Zhen Yuan. In fact, the Wise King received a secret letter from Shen Du, revealing the dangerous situation in the court, where many officers had turned traitor, while only General Zhen Yuan remained loyal. The Wise King quickly summoned the war general and led an elite force to wipe out Lai Luo Zhi's external allies.

In another twist, Brother Liang invented a powerful crossbow that can shoot three arrows simultaneously, significantly boosting their combat strength.

Lai Luo Zhi mentions the Fire Moth Sect, which has considerable influence across various regions. But Shen Du is prepared; Jiang Langxing has gathered talented individuals from all over to eliminate these strongholds one by one.

When the signal is given, Lai Luo Zhi finally reveals his trump card—claiming to be the son of Consort Shu and the last heir of the late emperor, asserting that he rightfully deserves the throne. This revelation shocks everyone present. He even references a prophecy by the national advisor, claiming to be the one destined by heaven.

At this moment, Yan Xing appears, cleverly blending in among the emissaries to expose the truth. It turns out that the national advisor was aware of Yan Xing's treachery but lacked solid evidence, so he could only hint at it through prophecy. Before his death, the advisor hid a crucial piece of cloth under the table, which was inadvertently taken by the illiterate Yan Niang to wrap her child. Yan Xing uses the fabric as a clue to uncover Lai Luo Zhi’s true origins—he is not of royal blood but the illegitimate son of Consort Shu and General Kong Shan.

Years ago, Consort Shu was forced into a marriage alliance, and with General Kong Shan deceased, she had to endure separation to protect her family's life, bribing palace officials to keep this secret. This long-buried case is finally brought to light.

Upon learning the truth, Lai Luo Zhi's spirit is crushed, and he is ultimately killed by soldiers. Shen Du vows to clear his father's name, and although Yan Xing has divorced him, he still cares deeply about the matter.

Determined to face it alone, Shen Du bravely steps into the palace. The Empress Dowager publicly presents grain sacks as evidence, revealing the truth behind Shen Bing Zhu's wrongful accusation. It turns out the granary was already empty, and Zhang Xiang's students were selling grain. When the war broke out, the grain could not be replenished in time, and to cover up his crimes, Zhang Xiang fabricated evidence of Shen Bing Zhu's collusion.

Zhang Xiang ultimately confesses, clearing the Wise King of any involvement. This court intrigue concludes with justice served, leaving many twists and turns that evoke deep emotions.
