Cao Cao's troops, not only Yangping Pass and Shangyong two roads, from Guanzhong to Hanzhong, suitable for the army to walk at least two, Cao Ren, Cao Hong all the way is a partial division, and the main force, Cao Cao is divided into three ways, Xiahoudun, Xu Huang, Zhang He led a team of men and horses to advance in three ways, but the defense here, Liu Yi had already made enough preparations before, occupying the advantage of geographical convenience, the battle between the two sides lasted for several months but still failed to capture a few passes.

The main battlefield is still on the side of Yangping Pass, and Huang Zhong and Wei Yan are now stationed separately.

In the first month of the nineteenth year of Jian'an, Liu Yi arrived at Yangping Pass, but it did not bring much change to the battle situation.

"Where is Ma Chao now?" In front of the huge sand table, Liu Yi looked at the mountains and rivers on the sand table, and frowned at Wei Yandao beside him.

After he left, Huang Zhong specially sent people to send this sand table to Yangping Pass, and later Cao Jun divided his troops to attack, Huang Zhong left Yangping Pass, but this sand table was not taken away.

"Since the defeat of last year, there has been no news of that Ma Chao, I heard that he has escaped into the Qiang land!" Wei Yan shook his head and said.

Liu Yi's thoughts, Wei Yan can also understand, if the horse exceeds the rear of the Cao army at this time, not to mention helping them deal with Cao Cao, as long as that Ma Chao makes a comeback, scourge Xiliang, it is best to capture a few counties, Cao Cao will have to consider the dilemma of being attacked by the enemy on his back.

Wei Yan also had this idea, he sent a letter to Ma Chao to advise, that is, he hoped to join forces with Ma Chao, but Ma Chao is nowhere to be found now, Cao Jun's army is pressing, it is already difficult to defend the city, and all the main roads are also blocked by Cao Jun, and now it is not easy to contact the outside world.

"Think of a way, this Hanzhong is also in the Qiang land, I don't know if those officials and generals in Hanzhong have any contact with the Qiang people, if they can contact that Ma Chao, or they can force Cao Cao to retreat." Liu Yi frowned.

Cao Cao is menacing, it is impossible to win a big victory like the Battle of Chibi, what can be done now is just to force Cao Cao back, Liu Bei has already hit the city, as soon as the city is broken, the next is Chengdu and Du, but Cheng and Du are not easy to fight, just like Jiangling, if it weren't for the new weapons provided by Liu Beijun at that time, plus the lack of defenders of Cao Jun, and the new warships were caught off guard, according to history, Jiangling Zhou Yu attacked for a year and did not take it down.

Cheng, all soldiers and horses are sufficient, in history Liu Bei just attacked Cheng, the capital attacked for more than a year, and in the end failed to defeat it, it was Liu Zhang who took the initiative to surrender, but now the Cao army is pressing, the situation has been different from history, at this time Liu Zhang may not surrender, as long as he is unwilling to open the city gate, Liu Bei wants to break the city is not easy, if Liu Bei can not successfully take Shu, Cao Cao may not retreat, and if Cao Cao does not retreat, Liu Zhang will still have the courage to defend it.

And now Cao Cao did not attack Jiangdong in this period as in history but led the army to come here, but Jingzhou's soldiers and horses could not move lightly at this time, Sun Quan's attitude was a little ambiguous, at this time, if the two joined forces, Jiangdong took the opportunity to send troops to Jianghuai, Guan Yu attacked Xiangfan, and Cao Cao would be able to retreat.

But just as Cui Zhouping analyzed with Liu Yi at the beginning, Sun Quan obviously did not want to see Liu Bei gain Yizhou at this time, and although Jingzhou's soldiers and horses did not have the threat of Cao Cao, they had to guard against the threat of Jiangdong.

Although under the persuasion of Liu Yi and Pang Tong, Liu Bei gained a lot of advantages in the early stage, and also won the fertile land of Hanzhong, and there were more soldiers and horses than in history, but the current situation is much more difficult than the situation in which Liu Bei captured Yizhou in history, but if it can be laid, the benefits obtained are definitely higher than in history, at least Liu Bei's foundation is more stable than in history or in Romance, and if Zhuge Liang, Zhang Fei, and Zhao Yun are not transferred to Shuzhong, Jingzhou is undoubtedly safer. Then Liu Bei's power will usher in a take-off, and the pattern of the Three Kingdoms will be completely settled since then.

But the premise of all this is to hold Hanzhong, and Liu Bei can successfully take Yizhou as the premise, it is not difficult to hold Hanzhong at the moment, and even Liu Yi can develop with peace of mind, but Liu Bei's side now seems to be in a bitter battle.

I don't know if there's anything wrong with Pang Tong's goods?

Wei Yanke didn't know Liu Yi's kung fu for a while, so many thoughts had already turned in his heart, and when he heard Liu Yi say this, he nodded silently: "The last general will give it a try, he captured some of Ma Chao's soldiers and horses before, and now it's time to put it back, see what Ma Chao means, if he is willing to send troops, it would be better." ”

Liu Yi nodded, but he was still a little worried in his heart, this question, he and Wei Yan could think of it, Cao Cao couldn't think of it?

But I can't take care of so much at the moment, it's always good to have one more helper, at this time, in order to fight against Cao Jun, it is natural to unite all the forces that can be united, and now it seems that only Ma Chao is left around.

Liu Yi didn't care much about guarding the pass, Wei Yan was much better than him, just looking at Cao Jun's formation, Liu Yi thought about it, and took a group of craftsmen to the top of the mountain, preparing to expand the camp on the mountain a little more.

Since the last time Pang De led his troops up the mountain to seize the camp, Wei Yan's attention to the two mountains has increased a lot, and when the troops are sufficient, the troops in the barracks on the two mountains are full.

Cao Jun came here, naturally also found the two mountains of the wonderful use, Xiahou Tang once wanted to capture the mountain camp for his own use, but in the face of the strong camp on the mountain, Cao Jun several times attacked the mountain but failed to attack, can only rest this thought.

What Liu Yi is thinking about now is whether he can take advantage of the mountain to build a few stone-throwing platforms on the mountain and throw stones directly into the Cao army's camp, without special polishing into stone bullets, only a large pile of gravel is needed, even if it can't cause too many casualties, it can make Cao's army uneasy.

Of course, this is also Liu Yi's idea, from the top of the mountain can attack Yangping Pass, but can not attack Cao Jun's camp, and small stones are not good, if you want to include Cao's camp in the scope of the rubble, Liu Yi has to set up a rubble platform in the direction close to Cao Ying, but in this way, the danger factor has increased a lot.

Liu Yi also relied on the Shu army's ability to fight in the mountains, so he dared to have this idea, pushed the large camp on the mountain down to the vicinity of Cao Ying, and then began to dig and build a platform in a place where Cao Jun could not reach.

Xiahoudun was also worried that the Shu army on the mountain would take advantage of the cover of the mountain forest to make a detour to sneak attack, so the trees around the barracks were emptied, and if the Shu army appeared in sight, they would be found immediately.

"Almost, any further on, will be discovered!" Liu Yi visually measured the distance between the two sides, shook his head with some regret and said, "This Xiahoudun is quite cautious!" Withdraw! ”

The soldiers responsible for protecting Liu Yi breathed a sigh of relief, this distance was too close to Cao Ying.

Liu Yi followed the elevator back to Yangping Pass, and Wei Yan hurriedly stepped forward to ask about the situation: "Sir, how is it?" ”

"No, the nearest place, the distance from Cao's camp is also three hundred steps away, although our catapult has a long range, but this distance is too far to reach." Liu Yi sighed, the two sides are in a stalemate at the moment, if the city is attacked, Xiahoudun has already learned the power of the Yangping Pass to defend the city, so he will rarely take the initiative to attack, but Wei Yan's side does not dare to attack rashly, in the field, the Shu army is obviously not the opponent of the Cao army.

In this situation, both sides know each other's weaknesses and strengths, and they also understand where their own strengths and weaknesses are.

The war has now reached a stalemate, and although there are still offensive and defensive battles every day, the losses on both sides are not too great.

At this time, Liu Yi's role has been used up, logistics, Yan Pu is doing very well, Liu Yi went to Huang Zhong again, the situation is basically the same, Liu Yi only helped to strengthen the city defense, after making some city defense equipment, he reluctantly returned to the Meridian Valley, the war has been fought until now, it is a stage of fighting endurance, to see who can hold out to the end, or Liu Bei gave up attacking Yizhou, or Cao Cao gave up attacking Hanzhong, these three armies were dispatched, don't look at Cao Cao's momentum, But the consumption of grain and grass is also a huge burden.

The Hanzhong side is a local war, and the consumption of grain and grass is relatively small, but it is also necessary to supply logistics to Liu Bei, who has now occupied many cities in Shuzhong, and can also provide a part of his rear.

This stalemate lasted until April, when the road to the Meridian Valley had been basically completed, and Liu Yi was building the final checkpoint, but the news from Shu made Liu Yi have to stop his work.

"What did you say?" Looking at the messenger in front of him, Liu Yi narrowed his eyes.

"The military advisor was seriously injured in the battle of Luocheng and was seriously injured, and the lord asked Mr. to enter Shu immediately to join the lord, and the Hanzhong Taishou was temporarily served by General Wei Yan." The messenger who had come to give the order bowed.

"How is Shi Yuan's injury?" Liu Yi looked at the messenger and asked.

Pang Tong, the unlucky bastard, still couldn't escape this catastrophe in the end?

"Because the military division has a lot of armor, the army is not fatal, and the military doctor has helped him diagnose and treat, and there is no danger of life, but he needs to be well recuperated." The messenger bowed and said, "Please leave as soon as possible, sir." ”

Liu Yi frowned, what could he do if he went? But at this time, Zhuge Liang really can't be transferred back, the situation in Jingzhou, without Zhuge Liang in charge, maybe there will be some chaos.

"Does the lord have any other appointments?" Liu Yi asked while ordering someone to pack up.

"The lord ordered people to go to Jingzhou, as for the specific order, I don't know the lowly position." The Courier shook his head.

"Let's go!" When Liu Yi heard this, he didn't dare to delay, he wanted to know what order Liu Bei ordered, if it was to recruit Zhuge Liang, Liu Yi must dissuade him, at this time, Jingzhou could not do without Zhuge Liang.
