To answer this question, we need to first understand the historical background and true situation of the Battle of Yiling.

The Battle of Yiling occurred in 221 AD, which was the second year after the establishment of the Shu Han dynasty. At that time, Liu Bei of the Shu Han dynasty decided to expand his territory by attacking the Eastern Wu. He sent his general Guan Yu to lead 700,000 troops to fight against the Eastern Wu army in the Yiling area. The Eastern Wu side, led by Lu Xun, had an army of only about 50,000.

Before the battle began, the Eastern Wu army adopted a series of strategies and tactics, such as fire attacks and water attacks, successfully defeating the Shu Han army. The Shu Han army also encountered some problems during the battle, such as insufficient provisions and scattered troops. Finally, Guan Yu was captured by the Eastern Wu, and the Shu Han army was defeated and returned.

From historical records, the Battle of Yiling was indeed a victory for the Eastern Wu army. However, the Eastern Wu army did not lose all 50,000 troops, but successfully defeated the Shu Han army and captured Guan Yu. Moreover, the historical records did not mention any unusual tactics or weapons used by the Eastern Wu, but rather relied more on the organization and command ability of the army, as well as its ability to adapt to the battlefield environment.

Overall, the victory in the Battle of Yiling was not solely determined by hardware conditions such as the size of the troops and weapons and equipment, but rather depended on the organization, command, and adaptability of the army. Therefore, the victory of the Eastern Wu army in the Battle of Yiling was not as mysterious as described in the historical novels, but it was also not entirely accidental.

Unfortunately, Liu Bei had already developed a rift with Zhu Geliang and did not bring him on the campaign. Even Zhao Yun was not brought along. If even one of them had been present, it would not have been so easy for the Eastern Wu to defeat the Shu Han army.

On the other hand, Sun Quan of the Eastern Wu, upon learning of the plan of the Shu Han invasion, immediately submitted to the Wei dynasty to avoid being attacked from both sides while also requesting support. He boldly used Lu Xun, which ultimately led to their victory in the war.
