Qin State decided to destroy Zhao’s soldiers. Qin Wang Yingzheng personally swears to teach him. With the hammer and drums, the morale of the generals increased greatly. Everyone admired the young King Qin with great admiration. There were several long live voices, Li Xin, Yang Ruihe, Wang Jian received the tiger talisman and the axe, and restarted a new round of war of annihilation.
In 229 BC, in the 18th year of Emperor Qin’s administration, the Qin State sent another three-way army to attack the State of Zhao. Seeing that the situation was in danger, he and Zhao Wangqian, together with the clan and ministers, returned to Wu’an Jun Li Mu. As a result, Zhao Dong and Guo Kai went back. It was a controversy. Li Mu believed that Qin's three routes wanted to encircle Handan, so he asked the frontier army to run a long distance to stop Yang Ruihe from the south and Li Xin from the north, and then confronted Jingxing with Wang Jian, looking for opportunities to defeat.
After Chan, he found the weak in Zhao, and asked King Qin how he was willing to stop the army and let him go. Then he answered that Zhao would not return, and Qin would never retreat. At this time, Zhao Tong told Chan that Li Mu had repelled Qin. Yang Duanhe who blocked Li Xin from the Great Wall in the South, now Li Mu is rushing to Jingxing to intercept Wang Jianzhi's army from attacking Handan. All the officials of the Qin State discussed the strategy of defeating Li Mu. Li Si proposed that he could not target Li Mu alone, but to separate the officials of Zhao State, which caused the conflicts in Zhao's country to rise, everyone in Handan at risk, and the suspicion between the monarchs and the officials.
Zhao Yu was worried about the tigers and wolves of the Qin army and told Li Mu not to underestimate the enemy, but Li Mu promised that he would be able to withstand the offensive of the Qin army. However, considering Wang Jianshan's long-term strategy, he might not be able to make up for it. The advocating girl ordered Zhao Tong and Guo Kai to raise grain and grass, but Handan City stored grain only for the army's needs for one month.
Guo Kai truthfully informed the Empress Dowager, and at the same time frankly confessed to Zhao Di’s successive years of disasters, the difficulty in raising millet, and the discord between Qi, Yan and Zhao, the traffic of other countries has been blocked by the Qin army. The Queen Mother thought that Qin Shidun was still weak in Handan, so he was immediately called into the palace and asked how King Qin would let go of Zhao. If he was weak, it meant that if Zhao did not return, Qin Duan could not retreat.
Guo Kai was scolded by Zhao Yan again at the gate of the Queen Mother’s Palace. Zhao Yan told the Queen Mother that Li Mu led his army against Qin and successfully repelled Qin General Li Xin and blocked Yang Ruihe of the Great Wall in the South. At the same time, he rushed to Jingxing to intercept Wang Jian’s army. For Handan.
As Li Mu used soldiers like ghosts and rushed like electricity, all the officials of the State of Qin discussed how to defeat Li Mu's strategy. Li Si proposed not to target Li Mu alone, but to separate Zhao Guo's officials, causing a sudden internal dispute and mutual suspicion. At this time, Guo Kai and Zhao Tong were arguing about raising grain and grass, and the queen mother asked his clan to raise funds to buy grain from other countries.
Guo Kai complained that Li Mu's army was a bottomless pit, so he took advantage of the opportunity to lobby Guo Kai to falsely accuse Li Mu of embezzling grain and grass, so that Zhao Guo could change his general. Guo Kai designed to falsely accuse Li Mu of fornicating the Qin State, advocated that the queen mother be deceived by Guo Kai, and then asked Li Mu to hand over the right to send troops. Zhao Yu came forward to stop him, saying that there must be something wrong with this matter. How could he have suggested that the Queen Mother would still send Guo Kai to Jingxing to recall Wuanjun Li Mu.
Guo Kai took Wang Ming to Jingxing and recalled Li Mu. On the way back, Guo Kai planned to ambush Li Mu, and Li Mu escaped.
