The next day, Li Hong really burned badly. After seeing Li Hong's illness, the www.biquge.info doctor of Pen, Fun, and Pavilion unknowingly poisoned Li Hong's medicine. After drinking the poisonous medicine, Li Hong's condition became even more serious. Li Zhi quickly found out that it was the Shou Taiyi who poisoned the medicine, and soon, the Shou Taiyi confessed that it was the abolished queen and the abolished concubine who instructed him to do so, and Wu Zetian on the side was also constantly fanning the flames, Li Zhi finally made up his mind to give the death of the abolished queen and the abolished concubine, but he couldn't bear it, so he ordered Xu Jingzong to deal with it on his behalf. Xu Jingzong, who was eager to invite meritorious deeds in front of Wu Zetian, sent someone to beat up the abolished queen and the abolished concubine, Xiao Shufei scolded endlessly, cursing Wu Zetian, saying that she would become a cat in the next life, Wu Zetian would become a mouse, and bite her throat for the rest of her life. Xu Jingzong was furious, and asked the hands and feet of Queen Wang and Concubine Xiao Shu to be cut off, and tortured them. Under the careful care of Wu Zetian and Mrs. Han, Li Hong's condition finally improved day by day. The tragic deaths of Queen Wang and Concubine Xiao Shu made Li Zhi feel very sad and extremely guilty, so he could only go to Mrs. Han to find comfort. Wu Zetian felt that all the important things had been done, so he set out to abolish the crown prince. At her behest, Xu Jingzong demanded that the crown prince be abolished and Li Hong should be made the crown prince.

Prince Zhong's biological mother, Liu, was heartbroken when she learned the news, and at the same time resentful, and decided to seek revenge from Wu Zetian. At this time, Wu Zetian had nightmares, and there were ghosts in the palace, and suddenly people in the palace began to panic. In fact, these were all planned by the Liu family of Prince Zhong. Wu Zetian first ordered to kill all the cats in the palace, and then personally went out to expose Liu's tricks, and after being recognized, Liu committed suicide on the spot, and the smell of blood in the palace became even heavier. After the haunting in the palace, Wu Zetian finally bumped into the affair between Li Zhi and Mrs. Han, and was crazy with jealousy, but she still loved Li Zhi deeply, and in order to heal Li Zhi's inner pain, she let her sister linger with Li Zhi, but she vowed to take back Li Zhi's love from other women. Prince Zhong's royal mother and birth mother were dead, and he was terrified. Prince Zhong took his henchmen Wang Fusheng and Shangguan Yi to secretly see the eldest grandson Wuji. The eldest grandson Wuji felt that he could no longer fight Wu Zetian, and was worried that the crown prince would be killed, so he came up with the idea of letting him abdicate in front of all the ministers in the court. The prince was loyal and grieved, Wang Fusheng was loyal to the prince, and he couldn't help crying when he saw this sad scene, he was unhappy for the prince in his heart, and hated Wu Zetian to death. After Prince Zhong voluntarily abdicated, Li Hong was made the crown prince, Chu Suiliang was demoted from Chang'an, and Li Yifu was promoted to Zhongshu Ling.

Li Yifu and Xu Jingzong conspired together, and Xu Jingzong was ready to falsely accuse Han Ying and Laiji of colluding with Chu Suiliang for rebellion. So above the court, Wu Zetian relegated these two people to remote places, and finally these people died in distant places. In this way, the right hand of the eldest grandson Wuji was suppressed and lost his previous power. During this period, Li Zhi's health was getting worse and worse, he suffered from dizziness, and it became more and more serious, and he couldn't read the recitals, and the government was handed over to Wu Zetian to deal with. Wu Zetian was very anxious about Li Zhi's condition, and asked the imperial doctors to come for treatment, but the imperial doctors were helpless. But then Imperial Physician Shen recommended a folk Langzhong Cui Heyi, saying that he was quite capable. So Wu Zetian summoned him to the palace and asked him to treat Li's illness. Cui Heyi proposed to use a steel needle to pierce Li Zhi's head and release bruises, Li Zhi was frightened and refused to be treated, but Wu Zetian boldly supported Cui Heyi, thinking that he could give it a try. When this matter reached the ears of the ministers, everyone was panicked, and some even suspected that Wu Zetian was plotting to kill Li Zhi and wanted to be the emperor himself. As a result, there was a tense air in the court. Some ministers played for this matter and impeached Cui Heyi for using witchcraft to murder the emperor, causing an uproar. At the instigation of the ministers, Li Zhi summoned Cui Heyi into the palace to punish him. Cui Heyi was willing to guarantee his life to cure Li Zhi's illness. He pulled out the steel and gestured at his head, saying that it would be fine to release a little bruising. Li Zhi was frightened, had a splitting headache, and suddenly couldn't even see his eyes. The ministers were indignant and wanted to kill Cui Heyi in the court. At the critical moment, Wu Zetian stepped forward, she loved her husband earnestly, knelt in front of Li Zhi, and begged Li Zhi to receive treatment in front of all the ministers with tears, Li Zhi was deeply moved by Wu Zetian's affection, and the pain at this time was worse than death, so he agreed to give it a try. Cui Heyi inserted the steel needle into the Baihui acupoint in the center of Li Zhi's brain, and then pierced the brain acupoint, blood gushed out, and all the ministers were terrified, and they all knelt on the ground. A miracle happened, and Li Zhi shouted, saying that his head didn't hurt anymore and his eyes were regained. Wu Zetian was overjoyed, and said again and again that this was a godsend! She rewarded Cui Heyi and left him in the palace to treat Li Zhi's illness. Everyone admired Wu Zetian's wisdom and decisiveness. The eldest grandson Wuji compiled his painstaking work "New Rites of the Tang Dynasty" and played it in the imperial court, wanting Li Zhi to promulgate and implement it, which was also a constraint on Wu Zetian. But Xu Jingzong deliberately found fault, and at the behest of Wu Zetian, he tore up the "Tang Xinli" in the court, and the eldest grandson Wuji was hit hard, and he was disheartened and no longer had the energy to go against Wu Zetian.

The eldest grandson, Wuji, was ready to return to his hometown and stay away from the strife of the imperial court, but he seemed to have a premonition that he was in trouble. At the suggestion of Wu Zetian, Xu Jingzong seized the handle of the crown prince Xima Wei Jifang and the supervising imperial history Li Chao, and weaved the eldest grandson Wuji into it, accusing them of conspiring with Liang Wangzhong and preparing to rebel. Li Zhi didn't believe it and asked Xu Jingzong to check again. Xu Jingzong fabricated a prisoner's confession and showed it to Li Zhi, who finally believed it. Wu Zetian took the opportunity to force Li Zhi to make up his mind, and Li Zhi issued an order to demote the eldest grandson Wuji to the governor of Yangzhou and settle him in Qianzhou, and Liang Wangzhong was also demoted to a commoner. Wu Zetian secretly ordered Yuan Gongyu, a scholar of the Xu Jing sect, to arrest the eldest grandson Wuji. The eldest grandson Wuji received the will of "giving death", and he was stubborn and maintained his last dignity, not wanting to embarrass others, burning incense and drinking, and then committed suicide by hanging himself. The abolished prince Zhong was demoted to a concubine and exiled to Qianzhou. He was only 18 years old at this time, and as the eldest son of the emperor, he lived a life of panic, often worried that Wu Zetian would send someone to assassinate him, and his nerves were highly tense and he became insane. He hoped that he would escape the catastrophe with this crazy appearance and leave a life. At this point, the eldest grandson Wuji and his henchmen, who had controlled the government for many years, were all wiped out, and Wu Zetian finally regained the emperor's real power from them, in fact, her own real power. Soon after, Wu Zetian gave birth to another daughter, Princess Taiping. Under Wu Zetian's careful care, Princess Taiping grew up happily.

The crown prince Li Hong has always been very close to Mrs. Han, and then heard rumors in the palace that he was born to Mrs. Han, Li Hong curiously asked Mrs. Han, Mrs. Han said that he was Wu Zetian's own son, but he also regarded him as his own son, but Li Hong was a very stubborn person, refused to believe it, and became closer and closer to Mrs. Han, and became estranged from Wu Zetian. Li Zhi and Wu Zetian drove the eastern capital of Luoyang, and let Li Hong stay in Kyoto to supervise the country, just when there was a great drought in Liaodong, Li Hong immediately ordered the grain in the palace to be distributed to the people. This move won praise from ministers and ordinary people. Li Hong also responded to the imperial court's decree that the soldiers who fled and their families should be confiscated as slaves, and Li Zhi relaxed the punishment according to the actual situation. Li Hong's benevolent name is known to the whole world. After Wu Zetian and Li Zhi returned to Chang'an, Li Zhi and Mrs. Han began to relive their old dreams. Wu Zetian was very jealous and felt that her own sister Mrs. Han might take away her husband and son, so she began to plan to murder Mrs. Han.
