When Shu Han and Wu are combined, the national power is half that of Wei.
After conquering Chang’an by conquering the North, we had to join hands with Wu to keep things in check and achieve something similar to conquering the world.
At least there is room to bring in immigrants from the western region.
In fact, in Chinese history, there is not a single dynasty that arose based on dispatch and succeeded by relying solely on topography and surviving.
Gongsun Shu was defending the universe in Bashok and was robbed by Emperor Guangwu of the Han Dynasty within a year, and Shenghan, which had been in Bashuk during the era of the 5th and 16 kingdoms, was ruined in one attack.
The only exception was Emperor Wu of Han, and he was only able to confront Xiang Yu after breaking out of Hanzhong and taking over Xiangyang (Changan) before Xiang Yu’s forces had established a foundation, and even then he had quite a few allies.
From Shu Han’s point of view, as time passed, the gap in national power with Wei gradually widened, so during the Zhuge Liang era, when Wei was unable to fully recover from the damage of the long war, there was no choice but to attack.
In fact, I almost succeeded to some extent on the first try.
Hehehe..
