Just when Cao Cao was writing hard and Xun You's face was full of sorrow, the horn of war sounded in the southwest of the Han Dynasty.

Liu Zhang appointed his general Pang Xi as the main general, and Li Yi, Pang Le, and Leng Bao as deputy generals.

led an army of 150,000 and went straight to Hanzhong.

On the other hand, Zhang Lu in Hanzhong also responded, Zhang Lu personally led an army of 100,000, with Yang Ren and Zhang Wei as deputy generals, and occupied Baishui Pass to the death.

At this time, the two armies were fighting one after another outside Baishui Pass, and Zhang Lu relied on the danger of Baishui Pass, which barely blocked the fierce offensive of Liu Zhang's army.

Zhang Lu stood on the Baishui Pass, looking at Liu Zhangjun, who was densely packed like ants below, with a solemn look on his face, this time Liu Zhang's attack was too sudden.

Some time ago, Liu Zhang's third brother's predecessor, Yizhou Mu Liu Mao, also wrote a letter to him personally.

In the letter, Liu Mao said that he hoped that they would temporarily put aside their estrangement and jointly fight against the enemy Jizhou Mu Liu Yuan.

Zhang Lu raised his hands and feet in favor of Liu Mao's idea.

If he hadn't gone with Liu Yan to participate in the princes' alliance before, he might have been dismissive of the Jizhou army.

But after the previous battle, Zhang Lu had long been apprehensive about Liu Yuan.

If it weren't for his luck and didn't follow the same path as Liu Yan, maybe he and Liu Yan would have died at Liu Yuan's hands.

So after Zhang Lu received Liu Mao's letter, he immediately replied to Liu Mao.

In the letter, he was very much in favor of Liu Mao's idea, and said that if he had another chance, he would definitely do his best to attack Liu Yuan.

But I didn't expect that before this letter arrived in Chengdu, the news of Liu Mao's violent death came, which made Zhang Lu unable to ease up for several days.

originally thought that this was already bad news, but I didn't expect that the bigger bad news would come one after another, and Liu Zhang, who took over Liu Mao's position, actually wanted to do something to his forces!

Originally, Zhang Lu thought that Liu Zhang was just talking casually, after all, because he had defected from Liu Yan before, Yizhou Jun didn't have any good feelings about him at all.

Liu Zhang, the newly appointed Yizhou pastor, is also very normal to talk about him, as long as the exact news of the world's attack on Liu Yuan comes, Liu Zhang will naturally give up this idea.

But what made him unprepared was that Liu Zhang's dispatch of troops this time was unusually sharp, he vetoed Huang Quan's persuasion several times in a row, and directly sent an army of 150,000.

Even because of this incident, Liu Zhang also locked up Huang Quan, the first resourceful man under him, and I heard that even Huang Quan's family may be implicated now!

Of course, Huang Quan doesn't care about his Zhang Lu's affairs, but Liu Zhang is menacing this time, and he once made a grand wish when he sent out the army, and Zhang Lu vowed not to withdraw the troops if he didn't destroy him!

Therefore, even if Zhang Lu knew that he could only lose both, for the sake of his own life, he had to use the strength of the whole Hanzhong to resist Liu Zhang's attack!

With the most elite troops and the most powerful generals under his command, he came directly to Baishui Pass at the junction of Hanzhong and Shuzhong, vowing to keep Liu Zhang's army out of Baishui Pass.

It's a pity that he underestimated Liu Zhang's determination this time, but this time Liu Zhang made up his mind to take Hanzhong back from Zhang Lu's hands.

Therefore, he brought out the most elite soldiers under his command, and with Huang Quan's experience, none of the generals under him dared to slack off.

All of them riveted their efforts to attack Baishui Pass, and for a while Baishui Pass was crumbling, if it weren't for Zhang Lu's soldiers, Baishui Pass would have fallen into Liu Zhang's hands.

This morning, Liu Zhang's troops launched three attacks on Baishui Pass again, and almost every hour, Liu Zhang's army will launch a fierce attack on Baishui Pass.

At this time, the city-guarding equipment on Baishui's closure had bottomed out, and even the boiling oil and arrows that had been prepared before were a little stretched under the rapid consumption!

If once the help of these city defense tools is lost, it will be impossible for Baishui Pass to resist at all, and Liu Zhangjun is so crazy to attack.

The day when these utensils are used up is the day when Baishuiguan is lost.

Zhang Lu was worried about this matter at this time, how could he replenish these city defense equipment to a relatively safe quantity in the shortest possible time.

As long as these things are replenished sufficiently, he has the confidence to continue to negotiate with Liu Zhang, but the most troublesome point now is that the heavens are not beautiful.

Some time ago, on the day Liu Zhangjun arrived at Baishui Pass, the originally cloudless sky suddenly changed its face, and it rained heavily for three days in a row.

The torrential rain washed down all three roads leading from Hanzhong to Baishuiguan, and the three roads, which were not wide in the first place, had become a vast ocean.

His convoy of transports is on the opposite side of the ocean, and as long as the road is cleared, it will not take two days to replenish the supplies, but it is too difficult to get the road clear!

Even if the water receded, the roads built of loess had already turned into a mud swamp, and the frames of the transport convoy could not pass through it!

This is tantamount to extending his lifeline indefinitely, and if the materials for defending the city are exhausted during this period, then he will have nowhere to run even if he wants to!

Before the road was not smooth, he was a turtle in an urn, and in order not to have this worst situation, Zhang Lu had already wanted to break his head.

But no matter what he thought, he couldn't come up with a strategy that could repel the enemy army, which made Zhang Lu a little frustrated.

Just when he was about to give up, his advisor Yan Pu came to his side.

After Yan Pu put a cloak on Zhang Lu's back, he said to Zhang Lu firmly:

"My lord, are you still worried about how to repel the enemy army? The lord can rest assured that the garden has come up with a strategy to retreat from the enemy. If Liu Zhang's fang doesn't take the initiative to retreat, he will definitely call all the 150,000 people to become the ghost of Huangquan! ”

"What, is this serious? If the general can find a way to repel Liu Zhang's army, then the general is the benefactor of the whole Han Dynasty, and even more so the benefactor of my Zhang Lu! The benefactor is on the top, please accept Zhang Lu's worship! ”

After hearing Yan Pu's words, Zhang Lu excitedly gave a deep bow directly to Yan Pu, if it weren't for Yan Pu's fast movements, Zhang Lu would have already knelt down in front of him.

Yan Pu worked hard to help Zhang Lu up, and at the same time kept comforting his lord:

"Lord, don't be like this, you can't stand it! The lord can rest assured, the garden will send someone to send a letter, if Pang Xipifu agrees to withdraw from the army, otherwise he will blame the garden for being ruthless! ”

After speaking, Yan Pu gave Zhang Lu a firm look, and then directly turned his head and left Zhang Lu's side, and half an hour later, a gap opened in the closing door of Baishui Pass.

A fast horse took advantage of Liu Zhangjun's inattention, and rushed out of Baishui Pass directly to Pang Xi's camp, after this fast horse left the city, the gate of Baishui Pass closed quickly again!
