Enter the Shu Han chapter of the Three Kingdoms All-Out War

In the early stages, liu lingjun led five tigers from Yong'an and rushed all the way west into Liu Zhang's liangchuan territory.
The Shu army is good at bows and crossbows, and the jungle gunners are strong, and the cavalry is the weakest, our army first attacked Linjiang to open the gateway into the river, and the Linjiang garrison was small, and it would be conquered in a few days. He followed Sun Qian's army division to plan a follow-up route.
It is advisable to fight a quick battle in the land of Shu, and if the confrontation under the dangerous pass is unfavorable to our army, our army is now flourishing. It is better to divide the troops into two routes, one route to the main prince and personal leadership, go north to Yanqu, and then attack Langzhong, which can be repaired in Langzhong and wait for reinforcements to gather.
The ambassador asked, "What about the other army?"
Qian replied: The other army can be taken from Yi Detong to Jiangzhou, Jian Yong is the military division, and Liu Feng is the deputy general, and yan Yan is sent to fight. General Zhang bravely crowned the three armies, needed to frustrate the spirit of the first battle, and then besieged but did not attack, waiting for the enemy's reinforcements to arrive, ambushing the army in a dangerous pass, and the reinforcements were destroyed, then yan yan would surrender, and then take it for his own use, for the vanguard of the advance, the Shu army could no longer stop it.
Let the king hear the great joy, and the king is the plot of the sub-house. Do as you go.
Suixi Road Army went down to Jiangzhou and surrendered to Yan. The lord went north into Langzhong to repair, and everything was as planned, but he was not satisfied with the water and soil in Shuzhong, and he was old enough to be sick. The Lord said bitterly: When the heavens are with me, how can I bear to lose an arm of mine?
The results of the bitter battle in March are as follows, and the aftermath develops, please see the next decomposition.
