In the 77th episode of The Three Kingdoms, Zhuge Liang thought that the master would spare me and directly ordered the old minister in Shu to handle affairs. What does this sentence mean?

After Liu Bei proclaimed himself emperor, Guan Yu and Zhang Fei were killed one after another. Liu Bei was bent on attacking Wu, and Zhuge Liang and other people who first followed Liu Bei opposed it, but Liu Bei did not listen to any opinions and set out to let Li Yan and other old officials in Shu prepare to attack Wu Zhigong. Zhuge Liang lamented this sentence. I feel in my heart that Liu Bei didn't regard him as a confidant in this matter. It is nothing to explore that such an important thing should have bypassed him. Finally, Zhuge Liang also chose to compromise!
