Zhang He's army attacking Yizhou. It was from Zitong to Fushui Pass, so they were facing the front of Fushui Pass. Xu Rongjun traveled south along Fushui Road from Gangdi Road, so he went around to the back of Fushui Pass and came to the front of Mianzhu Pass.

In other words, Zhang Hejun and Xu Rongjun outflanked Fushui Pass.

Fushui Pass and Mianzhu Pass are the last two gateways to the north of Chengdu, once lost, there is no danger to defend, and can only rely on Chengdu City to do the last desperate resistance. And Fushui Pass was before Mianzhu Pass, which could have played a big buffer role, but now it has become useless because of Xu Rongjun's copying of the back road.

The general who stayed at Fushui Pass was named Yang Ren, but he was an old acquaintance who was used to dealing with the troops of the Jin State and the Liang State. This goods followed Sima Yi north to fight in Hanzhong, and was almost not killed by the arrows of the vanguard army, and later fled to Yizhou after the defeat, and even the original nest Hanzhong did not dare to return.

Yang Ren waited for the vanguard army to attack on Fushui Pass, and after a few roars from General Shenwu's cannon, he fled to Mianzhu Pass. This way from north to south, the defenders of Yizhou did this, and those who fled and fled developed a good habit of moving when they heard the cannons.

It's a pity that Yang Ren made a mistake this time, the vanguard army fired a few cannons in front of Fushui Pass, Yang Ren led the three thousand guards in the pass to retreat to the Mianzhu Pass in the west, but met Xu Rong who had been waiting for a long time on the way. The Kunlun army was 30,000 people, and Yang Ren only had 3,000 men, and they were the kind of defeated soldiers who had already been frightened, so the two sides did not move at all, and Yang Ren took the lead in disarming and surrendering.

From Fushui Pass to Mianzhu Pass, there is a distance of about 60 miles, which is not too long. The vanguard army had previously attacked the city all the way and was invincible, which had already provoked the soldiers of the Kunlun army, so after Xu Rong captured Zhang Ren, he immediately ordered the army to pounce on Mianzhu Pass, hoping to capture Mianzhu Pass before Zhang He arrived, and drive the army into the Chengdu Plain.

However, when the high-morale Kunlun soldiers arrived at Mianzhu Pass, they were all stunned by what they saw, and they returned to their positions one by one, and none of them dared to greet the defenders of Mianzhu Pass with Shenwei General Cannon.

It didn't take long for Xu Rong, the commander of the Kunlun Army, to personally come to the Mianzhu Pass not far from the pass, carefully observing the situation under the pass. After reading it, he put down the telescope in his hand with a pale face, and then turned around and scolded several division commanders: "Today I can be regarded as understanding Sima Yi's despicable, shameless, and obscene...... I'm an eight-generation ancestor!"

It turned out that the chief general stationed at Mianzhu Pass was Sima Fu, the third son of Sima Fang, and in order to prevent Mianzhu Pass from turning into ruins under the fierce bombardment of Shenwei General's cannon, he actually rushed to build an earthen city several zhang high in front of Mianzhu Pass, and the city was filled with the common people of Yizhou in Mianzhu Pass, and roughly estimated, there were at least tens of thousands of people.

The Tucheng City that covers in front of Mianzhu Pass is much higher than that of Guancheng, and the people above can't go down to Tucheng even if they have food and drink. In fact, even if these people wanted to come down, there was no way, because there were no stairs to go up and down in Tucheng. At this time, it was already May, and the weather in Yizhou was warm and pleasant, and it could not freeze these old, weak, sick and disabled people. Every day, they could only wait for the soldiers in the pass to carry out the ladder to bring food and water to the city, and after eating, they would sit on top of the earthen city and chat.

What made the Kunlun army feel even more annoying was that the more than 10,000 people above Tucheng and urinated every day without covering it, and one by one they rushed the fart/strand of white flowers to the outward edge of Tucheng, just in front of the Kunlun army's eyes to solve the internal emergency problem.

It's not that the people on Tucheng are shameless, it's really that at the beginning of the construction of Tucheng, Sima Fu didn't consider building latrines for the people on the flat Tucheng platform. Maybe this is a means for Sima Fu to stimulate the city to attack the Yizhou army!

To put it bluntly, the Sima family used this hand to use the lives of the old and weak women and children in Wanyi Prefecture on the soil city to build a moral barrier for Mianzhu Pass!

Didn't you King Pingxi always boast that you loved the people and Ruozi? Didn't the armies of your Jin and Liang always boast that they were the teachers of benevolence and righteousness? I found more than 10,000 people, and they did not abuse them, but entertained them with good food and drink, and put them in front of the closed door to see if you still dare to bomb me with the cannon of the Shenwu general!

The Kunlun army was blocked by Sima Yi's desperate plan in front of Mianzhu Pass. Xu Rong once imagined sending a small force to approach Tucheng at night, and then set up tools such as ladders to go down to Tucheng to rescue the old and weak women and children in the city. Unexpectedly, the people above the earth city did not appreciate it at all, and scolded the Kunlun army as "bandit bullies", "man-eating demons", and "murderous robbers", not only refused to go down to the city, but also ignited the explosives hidden in their bodies and fell down the city with the Kunlun soldiers who finally climbed to the top of the city!

After losing hundreds of soldiers, Xu Rong became a little manic, and he really wanted to take the risk of going to the military court after the battle, and ordered the army to forcibly attack the city. Fortunately, without waiting for Xu Rong to give this order, Zhang He and Fu Zhu rushed to Mianzhu Pass in time and stopped Xu Rong.

Zhang He said to Xu Rong: "Even if we stop at Mianzhu Pass, we can't do anything to bombard the civilians of Yizhou." You don't know King Pingxi's temper, he really treats the common people as relatives, not for the world to see. ”

Xu Rong said anxiously: "Then our 70,000-strong army is just like this under Mianzhu Pass? If we can't destroy the Sima clan before Zhang Ren leads the army back to Chengdu, our brothers may die more than the people of Yizhou in Tucheng! This is the elite who is most loyal to the king of Pingxi!"

At this time, he suddenly remembered that Zhao Yun mobilized the people to ram the earth for the city before Huguan, and he had resisted the hundreds of thousands of allied troops attacking the East Road of Bingzhou, so he suggested: "Commander Zhang, Commander Xu, it is better for us to organize the army to build another slope earthen dam outside the Tucheng overnight, so that the army can board the Tucheng at the same time, so that the people on the Tucheng do not have to worry about the people on the Tucheng City attacking our soldiers." ”

Xu Rong retorted: "If the defenders of Mianzhuguan behind Tucheng discover our army's intentions and launch a counterattack against us regardless of the lives of the people in the city, it will cause heavy casualties to our army!"

Zhang He pondered for a moment, and then said: "Let's do it according to the strategy of the republican army first, when the earth dam is built close to the earthen city, if the attack of the guards is really fierce, we will make plans!"

Zhang He was the marshal of the Northern Route Army, and since he said so, he set the tone, so the two armies seized the time to act.
