After Wu Yi was defeated by Zhang Fei and Zhao Yun in Luocheng, he took advantage of the situation to escape from the battlefield. In order to escape from danger, he did not think about returning to Luocheng and ran directly to Mianzhu.

Although this defeat was purely an accident, it was quite smooth at the beginning and trapped Zhang Fei, the appearance of Zhao Yun's variable was unexpected by Zhang Ren, and they cannot be blamed.

In the eyes of Wu Yi and Zhang Ren, this is God's will. God is helping Liu Bei. Wu Yi thought that Liu Zhang's defeat was a foregone conclusion, so he left Luocheng decisively.

But no matter how you say it is, it is a defeat. Although it is the time to use people, Wu Yi still has thousands of elite soldiers, so he is not afraid that Liu Zhang will punish him.

But if you return to Chengdu, under Liu Zhang's nose, it would be a little difficult for Wu Yi to continue to gain a military force.

Therefore, Wu Yi had already made a plan and could not give Liu Zhang the opportunity to remove his military power. He needed a suitable reason to continue leading his troops outside.

He had no intention of returning to Chengdu. After retreating to Mianzhu, he used thunder to take over the city defense from the Mianzhu guards. He was as if facing a great enemy, closed the four gates and made a stance of being strictly guarded.

Then, Wu Yi immediately wrote a letter to Liu Zhang, reporting on the defeat of this battle. Although the statement was basically the facts, it was also clear that this defeat was Zhang Ren's responsibility. Because he had cut off his way back by Zhao Yun, he had no choice but to retreat to Mianzhu.

Shifting responsibility is certainly not Wu Yi’s main purpose. He mainly sells his new plan to Liu Zhang:

"Plant the second line of defense in Mianzhu and use Mianzhu as the last barrier to protect Chengdu."

Liu Zhang received a military report from Wu Yi because Liu Xun had already fled back to Chengdu and knew that what Wu Yi said was true and did not mean to blame him.

Just as he didn't know how to arrange this defeated soldier, he received a report from Wu Yi to stick to Mianzhu's plan, Liu Zhang immediately summoned his generals to discuss, and everyone agreed with Wu Yi's opinion.

However, Liu Zhang was also in a dilemma when sending reinforcements to Mianyang and Luocheng.

Although the Xichuan army and horses are as many as hundreds of thousands, most of them are in the hands of the aristocratic families. If they want to consider the future of the family, they will naturally not fully support Liu Zhang.

After Liu Zhang and Liu Bei started the war, they issued an order to gather troops, but less than half of the county magistrates sent to Chengdu were sent.

Moreover, most of the troops sent were mobs, and they could be used to defend the city. If they were fighting outside the city, they would be vulnerable.

Liu Zhang gathered about 100,000 troops, which was more than enough to defend Chengdu, but if he was sent outside the city, it would be a bit difficult!

Later, he finally sent 20,000 reinforcements, and Mianyang and Luocheng each received 10,000.

The reinforcements sent to Luocheng were led by Zhang Yi and Zhuo Ying, and the elite private soldiers of the Zhang family and Zhuo family were the backbone, and their combat effectiveness was not weak.

However, no one was willing to lead the reinforcements sent to Wu Yi, and they were not elite soldiers and generals, but Wu Yi was relieved.

Because in his opinion, the combat effectiveness of the army is second, and being able to protect his military power is the most important thing.

Wu Yi had 20,000 troops and was at ease to set up defenses in Mianzhu. The entire Mianzhu City looked like a wall of iron, but the major families in Mianzhu had their own thoughts and were ready to please both sides.

After Ma Su settled down in Mianzhu, he knew that this was the last obstacle for Liu Bei to march into Chengdu. He was originally planning to contact some aristocratic families and cooperated inside and outside when Liu Bei conquered the city.

After Ma Jian and his merchants, Ma Su quickly contacted more than a dozen small and medium-sized families. They were all willing to raise troops to respond, and they could assemble more than a thousand private soldiers. If they suddenly attacked when the two sides were fighting, it was very likely that the city gate would be opened.

However, Liu Bei followed Zhuge Liang's plan and prepared for a protracted war. After occupying Luocheng, he did not rush to march into Mianzhu. Instead, he sent Zhang Fei, Zhao Yun and others to lead the troops to wipe out the surrounding prefectures and counties.

Ma Su was waiting in Mianzhu City for more than half a month, but he could not wait for Liu Bei's army to attack the city, but he waited for Wu Yi's invitation.

It turned out that among the merchants Ma Su contacted, one of the people who was showing off after drinking, was discovered by Wu Yi's subordinates. Following the clues, he quickly found Ma Su's body.

Just so happened that Wu Yi also wanted to find someone to help him. After discovering Ma Su, he was not surprised but happy. He immediately sent someone to send an invitation to invite Ma Su to report on the county yard.

After receiving the invitation, Ma Su was also surprised, but after thinking about it carefully, Wu Yi should have no malice, otherwise he would have directly captured the army and arrested him, so there was no need to be so polite.

Ma Su knew that there was a great risk when he went to see Wu Yi, and it was also an opportunity. If he could convince Wu Yi to celebrate the city, it would be a great achievement.

When Ma Su came to the yamen, Wu Yi received him very politely.

The two knew it well and had a great time talking. After exploring each other, Wu Yi did not put forward any conditions and agreed to offer the city, which made Ma Su feel a big surprise.

After making an agreement with Ma Su, in order to show sincerity, Wu Yi personally wrote a letter to serve Liu Bei and handed it to Ma Su.

Ma Su, with Wu Yi's loyalty, left Mianyang with the guards and went to Luocheng to meet Liu Bei.

After Zhang Fei and Zhao Yun left, Zhuge Liang was not idle and began to prepare for the attack on Chengdu. He summoned a group of surrendered generals from Shu to discuss military information and asked:

"Where are there any passes that are under heavy troops to guard when they go to Chengdu?"

The surrendered general in Shu replied in unison:

"This time I went to Chengdu, there was a smooth journey, and there was no danger to defend. Only Mianzhu had heavy troops to defend; if I got Mianzhu, Chengdu would be within my reach."

Zhuge Liang was about to discuss the strategy of advancing, and Fa Zheng stood up and offered his advice:

"After Luocheng is broken, Shu is in danger. The lord wants to convince the public with kindness and righteousness, so the military advisor should not advance for the time being. Let me write a letter to Liu Zhang to explain the pros and cons, and Liu Zhang will naturally surrender."

Zhuge Liang knew that Fa Zheng was not sure of convincing Liu Zhang. He wanted to repay Liu Zhang's kindness, but he didn't want to attack Chengdu, so he happily replied:

"The words of filial piety and righteousness are the best." Fa Zheng wrote a letter and sent someone to Chengdu.

When news of the fall of Luocheng came, Liu Zhang was panicked and quickly summoned officials to discuss.

Everyone remained silent, and only Zheng Du offered advice:

"Although Liu Bei is now siegeing cities and grabs land everywhere, the number of troops is not large, and he does not have the ability to quickly capture Chengdu. The soldiers outside the city have not been attached because they do not carry baggage, so they all rely on collecting military rations on the spot. It is better to drive all the people in Brazil and Zitong to pass west of the Fu River. The granaries and grains are all burned, and the deep ditches and high towers are waiting for them. Liu Bei goes out to ask for battle outside the city, but we can't stand it. After a long time, there is a lack of military rations. Only a hundred days later, Liu Bei will withdraw his troops. At that time, I will take advantage of the opportunity to pursue him, and Liu Bei can capture him!"
