At this time, Liu Xiawu ran out of the secret room, and as soon as he saw Liu Chengzhi, he immediately bowed and said: "Master Liu, I don't know if I can see you again in the future, there are many puzzles about alchemy that no one answers, I just ask my predecessors to give me more advice in the future!"

Seeing that he was so polite, Liu Chengzhi hurriedly helped him up and said, "Senior Liu, don't call me senior! Thanks to you this time, my friend can turn the corner, and I don't know how to thank him!"

"Since you said so, I will now write down some of my alchemy experiences, you can figure it out, if you don't understand, just come to me in the Chengzhi Army! You just need to inform someone that the alchemy union senior Liu is visiting, and I will come out to see you!"

When Liu Xiawu heard this, he rubbed his hands excitedly and said busily: "Thank you so much Master Liu! Thank you Master Liu!"

Liu Chengzhi wrote down some of his feelings about alchemy in the alchemist union.

And Liu Xiawu took out a golden sign and handed it to Liu Chengzhi, so that if he had difficulties in the future, he could use the brand to ask for help from the local alchemist union.

At this time, Shangguan Ruyun had already woken up and said, "Brother Zhi, where are you now?"

Liu Chengzhi said softly: "You just have to rest, there is no danger now!" Then, help her back to Chengzhi's army.

At this time, Xiang Wuji led 600,000 infantry, and had already arrived at the city of Mianzhou and joined Liu Xiaoqi's cavalry.

Xiang Wuji was also a famous general for a while, and he was not in a hurry to enter the city, but was stationed about three miles behind Mianzhou City, ready to go. Liu Xingxing threw himself into a rat trap and did not dare to attack the city of Mianzhou again. The two sides have been facing off for two days.

Liu Chengzhi and his entourage quietly bypassed Liu's troops and came to Xiang Wuji's tent. Xiang Wuji was overjoyed when he saw that Liu Chengzhi was safe and sound, and he got together for a big banquet with Zhu Shanchang, Liu Xiaoqi, Liu Yan, Li Xiuqi and other generals, as well as Wang Chengwen, Liu Xiwu, Liu Yuhu and other ministers.

Liu Chengzhi said: "This Liu Xingshen is not an easy person, they have a lot of troops, and they are well arranged, and they are in a hurry, but they are afraid that it will be difficult to retreat from the enemy!"

After that, he stood up, bowed deeply to Liu Xiaoqi, and said, "If it weren't for General Liu, this time would be unimaginable, thank you!"

Liu Xiaoqi said: "The young master is humble, you have already achieved this achievement at a young age, and if you make a mistake, you will be able to correct it, which is really admired by the heroes of the world!

Liu Chengzhi said: "Then it depends on you, in the future, Chengzhi will no longer dare to underestimate the heroes of the world!

Liu Chengzhi then asked, "Do you have a strategy to retreat from the enemy?"

Xiang Wuji said: "Recently, I have discussed with you, and I feel that Liu Xingshen's troops are coming from afar, and they will inevitably be tired after many days of attacking the city.

Liu Chengzhi looked at the others, saw that everyone was mostly in agreement, thought about it, and said, "Perhaps, this is the best way at present!"

Two more days passed like this, at the beginning of the lunar month, and at night I couldn't see my fingers. At the time of the third watch, Liu Chengzhi, Liu Yan, and Liu Xiaoqi each brought 50,000 cavalry, horse bits, and hoof cloths, and quietly came to Liu Xing's army. Because of the lessons from the past, Xiang Wuji was also sent to ambush 100,000 infantry as a reserve in front of the battle, in case of emergency.

Liu's troops were divided into three, showing a trend of cornering. Liu Chengzhi attacked the easternmost camp and the camp with the largest number of troops, about 200,000 people.

At that time, the tent was extremely quiet, and a few soldiers patrolled the high fence. Liu Chengzhi and several masters in the army quietly climbed up and silently dealt with these patrols.

Chengzhi opened the camp gate, and 150,000 cavalry quickly entered, setting fire to it while slashing and slashing.

Liu's troops were tired from attacking the city for several days, and they were indeed unprepared, and they were killed by surprise. But soon this well-trained army was assembled and several fireworks were set off into the air.

Liu Chengzhi knew that the opportunity could not be lost, and when the troops of the other two battalions arrived, it would be difficult to deal with it, and shouted: "Everyone hurry up, their large army will be coming soon!"

However, Lau's troops were half-asleep with weapons when they slept. After reacting, under the command of their generals, they blocked the infantry in front and the archers in the rear, and instead launched an attack on Chengzhi's troops. Since the cavalry was most afraid of bow and arrow shooting, the Chengzhi army suffered many casualties.

Liu Chengzhili didn't expect Liu Xingshen to lead the troops so powerfully, and sent a signal to Xiang Wuji, who was ambushed outside, Xiang Wuji led the troops to come from the rear, just entered behind the archers, so he slashed all the way. Lau's troops did not know what to do for a while, and fell into complete chaos.

After a stick of incense, the troops of the other two battalions arrived, and Liu Chengzhi knew that Liu Xing was leading the troops like a god and the soldiers were well-trained, so he hurriedly ordered the front team of the Yunli army to change into the rear team and slowly retreat backwards.

At the same time, the city of Mianzhou lowered its gates, and the Chengzhi army withdrew into the city in an orderly manner.

Bows and arrows began to be fired from the city wall, and Liu's troops did not dare to continue the pursuit. I had to return to the camp.

Liu Chengzhi and Xiang Wuji counted the men and horses and found that the cavalry had suffered about 10,000 casualties and the infantry had 20,000 casualties. Since the previous battle with Geshu Buji was only a tired soldier, Liu Chengzhi had never fought such a well-trained army head-on, and remembered the frivolity of half a month ago, and couldn't help but sigh that he was a frog at the bottom of the well.

At this time, Liu Xingshen also counted the men and horses, and found that there were 50,000 infantry and 30,000 archers, and he was quite surprised by the combat strength of Chengzhi's army, and became more and more determined to get rid of Liu Chengzhi.

The next day, Liu Chengzhi withdrew his troops from Mianzhou City, stationed behind the city, and discussed with several strategists and generals how to defeat Liu Xingshen.

But there is no good solution. Half a month passed, and the weather gradually warmed up and the air began to become drier.

Liu's troops began to recuperate and no longer attack Mianzhou City, but they had no way to defeat the Chengzhi army, and the two sides attacked and defended each other, and each had its own victories and defeats, and the overall stalemate was present.

That day, Liu Chengzhi was bored in the tent. Suddenly, I heard a loud "bang" in the distance, and quickly called someone to investigate.

Because the sound was so loud, everyone didn't know what was going on, and they all rushed to Liu Chengzhi's camp, and they gathered after a while. When he was wondering, he saw the spies hurriedly report that the eastern wall of Mianzhou City had collapsed, and Liu Xingshen was leading the troops to fight head-on with the soldiers in the city.

It turned out that in the past half a month, Liu Shiingshen has been sending his soldiers to dig tunnels, leading to the city of Mianzhou, transporting sassal wood, supporting the city wall, and then hollowing out the soil under the city wall.

Today, when the project was completed, he ordered someone to pull off the sassal wood, and the city wall lost its support, and it collapsed completely, because Zhu Shanchang stationed 30,000 elite soldiers on the east city wall, and most of them died at once.

Liu Chengzhi and the others didn't know what was going on, but they all realized that the situation was critical and hurriedly led the soldiers to the east.

The fastest of Chengzhi's army was 100,000 cavalry, and it drove towards the east of the city.

When the cavalry was about to reach the east of Mianzhou City, countless fences suddenly rose from the ground to block the cavalry in front.

The front hooves stepped on the hind hooves, and there were many dead and wounded, and then Liu's archers shot hard behind the fence, and the cavalry of the Chengzhi army suffered heavy losses.

At this time, Liu Chengzhi was in the cavalry queue and shouted: "Everyone retreat first!"

Fortunately, the Chengzhi army was well-trained, and most of the cavalry withdrew. At this time, Xiang Wuji arrived with infantry and archers, and after a burst of shooting, the soldiers left behind by Liu Xing also retreated.

By the time Chengzhi brought his troops to the east of Mianzhou City, Mianzhou City was already in shambles, and only half of the 200,000 soldiers in the city were left. Liu Shiing, however, was not in love with war, and quickly led the troops to retreat and pull up the camp.

After counting the men and horses, Cheng Zhi's army killed 200,000 infantry and 30,000 cavalry, watching these carefully selected soldiers fall in front of him, Cheng Zhi felt aggrieved, but he had nowhere to tell, and under anger, he spit out a mouthful of blood and fell off the horse.
