Zhuge Liang had seven grains of rice in his mouth to protect himself from falling. As long as Zhuge Liang's star does not fail, Sima Yi will not dare to make a move. The ancients studied astrology very deeply. Zhuge Liang can not only borrow the east wind from the sky, but also understand the world events by observing the sky tonight. Zhuge Liang didn't come out of the mountain in his early days, but he worked in the thatched cottage, but he knew the world situation like the back of his hand. When Liu Bei visited the cottage, Zhuge Liang, who had been living in seclusion in the mountains, knew more about what was going on in the world than Liu Bei. Legend has it that Zhuge Liang has superhuman stargazing ability and can predict everything. ?

It is said that Sima Yi saw Zhuge Liang's general star fluctuate for a while, then turned red and then fell from northeast to southwest. This made Sima Yi very happy, because Zhuge Liang died and there was no successor in Shu. Only lazy Liu Chan can't stop our army's attack. So he immediately ordered the officers and men to prepare for the attack on Shu.

However, just as the army had just stepped out of the stockade, he looked up at the sky. At this time, he saw the fallen fuses iconic still hanging in the sky. At this time, the red fuse is flashing but has not yet fallen. Sima yi immediately felt that something was wrong. This may be Zhuge Liang's plan to lure the enemy, so he led the troops back to camp. ?

On the other hand, Zhuge Liang can't afford to get sick because he borrowed his life from heaven. But in order to safely withdraw the leaderless Shu army, Yang Yi received an order that after my death, you can't send out obituary and don't be scared. It is best not to walk a little, and then immediately withdraw from the Northern Expedition to recover the Central Plains. Don't let anything unusual happen to the army after my death. Put me in a big niche, then put seven grains of rice in my mouth for me to hold, and finally light a lamp at my feet. This will keep my fuses iconic from falling, so Sima Yi naturally doesn't dare to do anything. You quickly withdraw your troops and go north to recover the Central Plains.
