He Jingzhong, the Minister of the Ministry of Personnel, was in jail because of his son and was seriously ill and could not go to court. As a result, the affairs of the Ministry of Personnel were piled up, making King Yu anxious.In desperation, Qin Banruo proposed Li Daitao's plan.

Yan Yujin and Xiao Jingrui returned from the hot spring to visit Mei Changsu and brought several baskets of tangerines shipped from Lingnan Prefecture.Everyone tasted it together. Yujin was as sweet as glutinous rice. Feiliu peeled it open and smelled it but threw it away without eating.Fei Liu's rejection made Mei Changsu realize that citrus fruits might have a peculiar smell.

Shen Zhui reported to King Jing that he had found black fire in the water transport and that it had been transported to the prince's private cannon workshop.Shen Zhui decided to take away the artillery workshop when the evidence was complete.

Mei Changsu was getting weaker and weaker day by day, so he begged Mrs. Yan to let him live longer.Prince Jing comes to visit and informs Mei Changsu that Concubine Jing found out that the queen was poisoned by the poison of rhizome.This herb is not very poisonous, but eating it can make your limbs weak, and it can only last for six or seven days.Mei Changsu, who was lost in thought, subconsciously made Lin Shu's habitual movements, making King Jing think of his old friend.Mei Changsu reminded Prince Jing that as the battle for the heir apparent became fierce, he would soon be pushed to the top of the wave. If he wanted to win, he would need both sincerity and skill to control the situation.

Concubine Yue recommended to Emperor Liang that Concubine Xu Shu perform the queen's ceremony during the year-end ceremony, which greatly pleased the dragon's heart.Li Gang reported that the other two ships of black powder were not transported to the private artillery workshop, but their whereabouts have never been traced.Mei Changsu analyzed that gunpowder was not used to make firecrackers, so it must be used to kill people.He associated the poisoning of tangerines and Queen Yan with the year-end festival. He realized that the situation was urgent and hurriedly paid a visit to Yan Hou regardless of Dr. Yan's obstruction.

When he went out but did not return, Yujin sent people to look for him.Mei Changsu, Yujin and Jingrui were chatting and waiting.Yujin talked about how he admired Lin Xiangru the most and thought he was the most envoy-like.Mei Changsu told him that there was such an envoy in this dynasty.37 years ago, the tripartite alliance of Dayu, Beiyan, and Donghai overwhelmed Daliang with five times the force.This envoy went alone, fearless of life and death, fought with the Confucian scholars, divided the three kingdoms, and resolved the crisis.Yujin praised him repeatedly.Mei Changsu told him: This man is your father! Yujin was shocked when he heard this.

King Yu investigated the Queen's poisoning case in the palace and found out that it was not the Crown Prince, but the person behind it still had no clue.

Waiting to return home.Mei Changsu went straight to the point, saying that he had found out the truth and buried the gunpowder in the altar.When asked about the reason, Yanhou said bitterly: I want to kill him! It turns out that Yanhou, Generalissimo Lin Xie and Emperor Liang grew up together since childhood, and the three of them made an oath to share hardships and wealth together.But after helping Emperor Liang ascend the throne, Emperor Liang not only enjoyed exclusive imperial status, but also did not care about brotherhood at all.He knew that Lin Xie's sister Le Yao had already been committed to Yan Hou, but he forced her into the palace.Later, Le Yao gave birth to Jing Yu (King Qi) and was named Concubine Chen.Yanhou accepted his fate and planned to let go, but unexpectedly another case of the Red Flame Army occurred - Jing Yu was sentenced to death, Le Yao committed suicide, and Lin Xie's family was in trouble! Yanhou hated the cold heart of Emperor Liang, pretending to be single-minded, planning for many years, and only wanted to kill.He takes revenge.

Mei Changsu tried his best to dissuade Yanhou.It is said that he is just venting his personal anger, not real revenge.Although the emperor is dead, the two factions of the prince and the prince are fighting, the government is unstable and the border is unsafe; Chi Yan's unjust case has not been settled, and the stigmatization of relatives and friends is still there; even Yujin, who has never enjoyed his father's love, will be implicated...…

At the same time, Meng Zhi, who was patrolling the palace, took out the fuse buried in the altar.
