Sure enough, I knew that Boss Cao would not be so kind to give Ma Chao a chance to breathe, and then Ma Chao was also a brainless person. At this time, even the weak and the strong were the right thing to do, and he had to come to serve as a gun envoy for Lao Cao. Now, Hanzhong has not been captured and the old nest has been raided. Why bother?

Looking at the latest information sent to him by Huang Zhong, Liu Yi smacked his lips. He was not surprised by the experience of Ma Chao kicking him out by Lao Cao. The battle between princes is not just about fighting hard, but also depends on his brain. Ma Chao obviously failed to find the right path. Now he retreated to Didao, which can be considered completely kicked out of this game of princes fighting for hegemony.

Although there are still some soldiers in my hands, they are just rootless floating duckweed. If you still choose to work alone, you can only be considered a group of more powerful bandits, and even warlords cannot be considered.

Why bother?

Liu Yi put away the letter and walked out of the shed with his hands on his back. Looking at the busy construction site, he was thinking silently that Ma Chao was defeated, and then the next time was Boss Cao's performance. Liu Yi was not too worried at Yangpingguan, but it was hard to say about Shangyong. Although Liu Yi has been running around for construction since Liu Bei's army arrived in Hanzhong, most of them are developing people's livelihood and water conservancy. The city defense on Shangyong has not been improved, and now I don't know if it is too late.

A burst of cheers came from afar. Liu Yi looked at him and said that the bridge, which was expected to be thirty meters long, was finally completed after these days of construction. It is no wonder that craftsmen cheered. This kind of suspended bridge that is thirty meters long is naturally not a strange thing to be placed in later generations, but in this era, it is amazing.

There is no load-bearing in the middle, and the load-bearing force in the middle of the bridge is completely scattered to both sides by relying on the support. The height of the bridge is less than two meters, but the bracket below is ten feet long, perfectly dispersing the weight of the center of the bridge to the cliffs on both sides.

"Sir, I've succeeded, please check it out!" A craftsman came to Liu Yi, with an unconcealed joy in his expression. This bridge of this level was built from their hands, and the sense of accomplishment was even higher than the money reward.

"I'm sorry for everyone!" Liu Yi looked at the bridge and was quite moved. From design to construction to completion, nearly a thousand people took action on the bridge nearly 70 meters, and it took a full month to complete it. But in Liu Yi's opinion, it was worth building such a bridge.

"If you follow the sir in this way, not to mention thirty feet, even a hundred feet bridge can be built!" a craftsman smiled excitedly.

"It's impossible for Baizhang, so this bracket has reached the bottom of the cliff. It's better to build a few pillars directly." Liu Yi shook his head when he heard this. The Baizhang Bridge, you don't need to think about the current level. Even the thirty-foot bridge in front of him consumed a lot of energy, but the effect was really good.

Perfect stone bridge: vision +35, extreme solid +34, load bearing +36, peaceful spirit +35, relaxed and happy +37

Not only is the perfect attribute, but most importantly, it seems that my experience also entered the second half of Level 6 with the completion of this bridge and began to sprint towards Level 7.

"This bridge has been completed, and the problem in the Ziwu Road has been completely solved. The next project requires everyone's efforts. It must be completed within half a year." Liu Yi was not ready to continue to stay in Ziwu Valley. Cao's army arrived at any time. As the acting prefect of Hanzhong, it would be a little wrong if Liu Yi did not come forward at this time. The more difficult parts of Ziwu Valley have been completed, and the rest of the places only need to hire craftsmen. In order to prevent Cao Cao from sending troops here again, Liu Yi specially left two schools of troops and stationed on the main road. In terms of the terrain of Ziwu Valley, it is enough to guard the main road.

"Sir, are leaving?" several craftsmen said in surprise.

"Well, now that the great enemy in Hanzhong is coming, I can't stay here anymore." Liu Yi nodded. The construction of the Ziwu Road has reached its peak, and the rest is only necessary to follow the steps. Liu Yi ordered a few craftsmen as the leader. When he was not there, he was responsible for supervising the construction work and completing this road as quickly as possible. The end point had to be set up. Because Xiahou Yuan had died in battle, the checkpoint would start immediately. Liu Yi had already drawn the drawings and waited for the construction, and the soldiers of the two schools would be stationed in it.

Then several craftsmen remembered that Liu Yi was not only a craftsman, but also a responsibility to hold the rear for Liu Bei. He immediately bowed to Liu Yi and said, "Sir, don't worry, this place is left to us. With the current project progress, the Ziwu Road will be repaired within half a year."

After all, it is not the road to future generations, and it needs to be excavated and laid. Coupled with Liu Yi's unique ability, these craftsmen and civilians can obtain extremely high craftsmanship in a short period of time and lay them out very quickly.

The next morning, after Liu Yi distributed the coins sent from the rear to a group of craftsmen, he arranged a general brought from Jingzhou to be responsible for guarding Ziwu Valley. He then took his personal guard out of Ziwu Valley and headed straight towards Shangyong.

...

More than half a month has passed since Zhang He captured Ji County and other places with the assistance of Yang Ang. Ma Chao retreated and walked away from Didao and entered the Qiang land. For the time being, Ma Chao no longer threatened Cao's army.

"Have Miaocai received a message yet?" In Chang'an City, Cao Cao nodded with satisfaction after reading the battle report sent by Zhang He, and then asked.

"The roads in Ziwu Valley are difficult to walk, and they are rarely crowded all year round. A few days ago, the land of Hanchuan suffered heavy rain again. General Miaocai will inevitably delay some of the speed of the march." Cheng Yu smiled and said, "The roads in Ziwu Valley are considered a surprise weapon. The real highlight depends on Cao Cao's main army.

Cao Cao nodded and said, "Since Ma Chao is no longer able to send troops to harass him, he ordered Yuan Rang and the two of them to immediately send troops to attack Yangping Pass, and ordered Zi Xiao and Zi Lian to send troops from Nanyang to Yong to attack Hanzhong. This time, the three groups of troops were sent to take Hanzhong."

"Here!" Cheng Yu bowed and took the order and left.

...

Although Cao Cao had never taken action, in fact, the deployment of Cao's army had already begun to operate secretly before Ma Chao left Hanzhong. Now, with Cao Cao's order, Zhang He, who had occupied Hanyang County, and Xiahou Dun set out from the extreme and Ji County at the same time, with the troops aimed directly at Yangping Pass.

At the same time, Cao Ren and Cao Hong, who were stationed in Nanyang, met in Zhuyang and directly seized Shangyong, Fangling and Xixian counties.

The war in Yangping Pass was guarded by two generals Huang Zhong and Wei Yan. In addition, Yangping Pass itself is strong, easy to defend but difficult to attack, and with sufficient troops, it is relatively easier to defend. After Liu Yi left Ziwu Valley, he rushed to Shangyong on a night and prepared to resist the Cao army from Nanyang here.

"Sir, don't worry, Cao's army is still in the Zhuyang area, which is three hundred miles away. In addition, the road is difficult to walk, so it will take at least ten days to reach here." Meng Da, who was stationed in Shangyong with Liu Feng, smiled at Liu Yi who was coming to Xingye and said, "Sir, since he is here, you might as well meet the gentry in Shangyong area first."

"Both are generals, and this military affairs are more important than me." Liu Yi did not go to rest. He sat in the main seat, looked at Meng Da and shook his head, "You should know the principle of the inconstant situation of soldiers than Yi. Cao Ren and Cao Hong are famous generals under Cao Cao, and they are well-versed in military strategies. Now that they have sent troops, it means that their troops can arrive here at any time. How can our army slack off?"

Information may not be completely useful. In this year, most of the information is obtained by scouts and detectives disguised in disguise. If the enemy is willing, they will release a few fake news to confuse the opponent and secretly launch a surprise attack. However, it is normal that those ten days are just normal marching speed. If you march in a hurry, it may not take that long.

"What sir said is good." Liu Feng nodded. He had fought with Liu Yi and was quite convinced of Liu Yi's ability. He asked for advice now: "I wonder how our army should defend?"

"This battle is intended to repel Cao's army and prevent Cao's army from having the opportunity to attack Hanzhong. You should understand what we are going to do first." Liu Yi looked at the map in front of him. Liu Yi, who was used to watching the terrain on the sand table, was not as dazzling as it was at the beginning, but he was still a little uncomfortable with this map: "So start with Fangling, set up defense step by step, don't be afraid of waste. As long as you can defend the two cities this time and save time for the lord, no matter how much preparation is worth it. I want to focus on Fangling and Shangyong, stationing in each dangerous level, defend step by step, destroying the enemy's spirit, and also buy more time for our army to strengthen the city defense."

Shangyong and Fangling are both located on major transportation roads, and the city is surrounded by the level checkpoints. Liu Yi is planning to build a few more. If it can disperse the forces of Cao's army, it is the best. If it cannot, it will be difficult to defend against the Cao army. The Cao army will be able to catch each level, and it will take a lot of time alone.

As for Shangyong and Fangling, the two cities must be strengthened, and these two cities will block the main force of Cao's army.

As for Xi County, some adjustments are also needed. Although Xi County is relatively remote, there are not many garrisons. If the other party regards this as a breakthrough, Shangyong and Fangling counties are likely to be attacked from front and back, so Xi County cannot ignore it. At least the garrisons must be increased. Before Liu Yi set out from Ziwu Valley, he had already returned to Nanzheng and mobilized 5,000 troops to Xi County to garrison. Shangyong and Fangling, the two cities combined, the garrisons had 13,000 troops. However, the information of Cao's army has not yet been fully returned, and Liu Yi did not know whether these personnel were enough. There should be enough troops and horses in the Nanzheng area to prevent the Cao army from coming out of some corner, and it will be arranged in this way for the time being.

This time, Cao's army sent troops to attack Hanzhong. As Liu Yi, who guarded the rear of Liu Bei, was naturally under the pressure, so he was not so polite at this moment.

"Send scouts to search for Cao's army along the way. Be sure to know the movements of Cao's army. In addition, you have sent a thousand civilians for me. You have been here for a long time. You should know the terrain here. Draw dangerous places on the map and prepare to build checkpoints in these places." Looking at Liu Feng, Meng Da and others, Liu Yi didn't care whether the other party agreed with his proposal. They are now in sufficient force. Instead of guarding the city and other enemies to fight, it is better to set up defense step by step and use these levels to delay the pace of Cao's army.

"Here!" Liu Feng, Meng Da, seeing Liu Yi's seriousness, did not dare to neglect, and each bowed to take the order and left...
