Shan Fu, who had lived in Jingzhou Water Township for a long time, quickly thought of the way to set up a temporary pontoon bridge to cross the river, Liu Zhang immediately agreed after hearing it, thinking that the powerful boat and bridge troops of the PLA in the future would build a pontoon bridge on the Yangtze River in forty minutes, although the current equipment is far less than PLA, but it is not difficult to build a pontoon bridge on the Jingshui River that is only ten or twenty zhang wide.

Liu Zhang agreed with Shan Fu's opinion, but he had other plans, thinking of a text called "Flying to Capture the Luding Bridge" in elementary school, he decided to build a rope bridge by imitating the Luding Bridge. Liu Zhang immediately handed over the task to the Tiger Guard Division, all the officers and soldiers of the Tiger Guard Division are well versed in various tactics, and water warfare is not inferior, at this time among the 70,000 or 80,000 troops, only they have the best water quality, let them fight with the river, build a pontoon bridge is undoubtedly the best choice.

Zhou Cang personally went into battle, took more than 20 soldiers into four small boats, and the long bamboo poles were propped up at the bottom of the river, and the small boats dragged ten strands of hemp rope as thick as a child's arm to rush to the opposite bank.

The distance of more than ten zhang passed in a blink of an eye. Without waiting for the boat to get steady, Zhou Cang pulled a hemp rope and jumped ashore, some of the other soldiers followed his example and jumped ashore with the rope, while others worked together to drag the boat to the shore, and then hurried to catch up with Zhou Cang.

The place to build the rope bridge has long been selected, Zhou Cang and the soldiers of the Tiger Guard Division pulled the hemp rope to a higher place, and greeted them, and the soldiers who had already crossed the river immediately stepped forward to help......

Zhou Cang had people cut more than 30 thigh-thick logs, and then smashed them deep into the hard soil four or five zhang away from the river with river stones, and then tied the hemp rope tightly to the wooden stakes, in order to ensure safety, each hemp rope was supported by at least two wooden stakes, and tightly tied with a thin rope to ensure that nothing went wrong.

When Zhou Cang was busy, the south bank was also working hard, when Zhou Cang said that the north bank had been firmly behind, the soldiers on the south bank were a group, each group pulled a piece of hemp rope, until the hemp rope collapsed, and immediately tightly wound it on the wooden stake on the south bank, and after the same rope was reinforced again, several soldiers braided the thick bamboo poles that had been cut off one after another on the hemp rope......

Zhou Cang naturally did not stop, Liu Zhang commanded people to weave from south to north, and he did it himself, starting to weave from north to south, and the progress was extremely fast. Finally, before sunset, a rope bridge across Jingshui was built that could accommodate four people or two horses in parallel.

Liu Zhang ordered many torches to be lit on both sides of the river, and the vicinity of the rope bridge was illuminated as if it were day, and the army immediately began to cross the bridge.

Although the rope bridge was a little shaky, at least it was sturdy, and the distance was relatively short, so the soldiers who were difficult to adapt to closed their eyes and took the hands of the people around them, and the speed was extremely fast.

People overcame it and passed, but the war horse was not moved at all, no matter how the soldiers drove it, the four hooves were like nailed to the ground, Liu Zhang suddenly thought of using the donkey to pull the grinding, let people use cloth to cover the horse's eyes, and the soldier held the reins, and the war horse crossed the rope bridge without panic.

The bridge deck made of bamboo poles is a little slippery, fortunately, the soldiers at this time are wearing bast shoes on their feet, the anti-skid effect is good, and those who occasionally stumble are also blocked by the guards on both sides, so as not to fall into the water.

After a whole night's effort, the army finally crossed Jingshui.

In the order of crossing the river last night, Liu Zhang put Beigong Yan's cavalry in the first place, and they who were the first to complete the river crossing had rested for almost the whole night, and as soon as the sky was bright, Beigong Yan led his troops to pursue Dong Zhuo. The other soldiers were unusually tired because they had been busy all night, and Liu Zhang ordered them to rest for two hours before setting off.

Liu Zhang's army was blocked by Jingshui for most of the day, and Chen Gong, who traveled day and night, took this opportunity to shorten the distance with Liu Zhang, and two hours later, Liu Zhang set off again, accompanied by 12,000 more troops and several tiger generals.

Beigong Yanxin voted for Liu Zhang, eager to make meritorious contributions, he was not allowed to stop for a moment along the way, eating and drinking were solved on horseback, and the army was like a strong wind looking for Dong Zhuojun's traces and galloping north.

The retreat plan formulated by Li Ru was not hidden from Beigong Yan, and with the confirmation of the traces along the way, Beigong Yan dared to conclude that Dong Zhuojun had entered the border of the state. After coming to this judgment, Beigong Yan couldn't help but hesitate for a while, there were two forces competing in Bingzhou at this time, if he took the liberty to lead the army into Bingzhou, would it cause any trouble? Will Liu Zhang blame him afterwards? But if he didn't act immediately, Dong Zhuo might have escaped, did he have to watch the great work in his hands slip through his fingers?

Beigong Yan is still a relatively decisive person, and after thinking for a while, he decided to continue the pursuit, he understood that Dong Zhuo, who ran hundreds of thousands of Xiliang, was always Liu Zhang's henchman, as long as he could catch up with Dong Zhuo, entangle Dong Zhuo, and give Liu Zhang a chance to eliminate Dong Zhuo, then he would have no merit! As for what to do if he can't catch up with Dong Zhuo, he has never thought about this kind of thing, don't look at Dong Zhuo's advantage of a day and a half, and there are a large number of horses and vehicles, but most of the wounded soldiers in the Xiliang army are carried, and they carry a lot of materials, and their speed is far inferior to him, and it is harder, and he will be sure to catch up with Dong Zhuo in less than three days.

Liu Zhang couldn't help but be a little worried when he learned that Beigong Yan had chased him into the territory of Bingzhou, don't look at Lu Bu and Yuan Shaozheng in Bingzhou, but once they learned that their soldiers and horses had entered, would they think that they were fighting with them and making a profit? If so, what choice will they make? Do you continue to fight for life and death, or put aside the controversy and work together to break your hand that stretches out the line? Moreover, there are Xiongnu activities in the western part of Bingzhou all year round, if the Xiongnu elite cavalry attack, can it be resisted? However, if Dong Zhuo is allowed to flee back to Wuwei, in three or five months, Dong Zhuo will have another 100,000 elite soldiers......

Liu Zhang was about to ask Xu Chu to invite Xun You, Xi Zhicai, Jia Xu and others to come to discuss, but after thinking about it in a blink of an eye, he dispelled this idea, because after Beigong Yan entered the state first, there were not many options left for him, and it could even be said to be the only one! What's more, Liu Zhang is not willing to miss the opportunity in vain. Liu Zhang immediately ordered a clerk to write a letter and ordered someone to send it to Lü Bu immediately, in which he explained to Lü Bu the reason why he would lead the army into Bingzhou, and assured Lü Bu that he had absolutely no intention of getting involved in the annexation, but was just borrowing the road......

In fact, Liu Zhang overestimated the importance of the western part of Bingzhou to Lü Bu. At this time, the Huns in the upper county in the western part of Bingzhou were in trouble, and Lu Bu focused on dealing with Yuan Shao, and he had no energy to pay attention to others, and the western part of Bingzhou was inaccessible, and the taxes were almost zero, in Lu Bu's view, it was a barbaric land, and not only could not collect taxes and levy strong men, but also had to garrison troops to guard against the Huns, which was tantamount to carrying a heavy burden in vain, this kind of thankless thing Lu Bu thought that only a fool would be willing, so Lu Bu's control over this was very weak, just a buffer zone, It used to be with Dong Zhuo, and it should be with Liu Zhang in the future, as long as Liu Zhang doesn't covet Taiyuan County, this burden Liu Zhang is willing to carry it, so it's good to carry it.

It's a pity that Liu Zhang doesn't know about this, he thinks that there are Lu Bu, Yuan Shao, and even the Huns in the territory of Bingzhou, and there are Xianbei peeping outside, it is already a pot of porridge, if he mixes it with another kick, this pot of rice will not be able to swallow, it is because of the fear of falling into the quagmire, so that he missed a good opportunity in vain, otherwise he can occupy Shangjun, slow down Taiyuan, once Taiyuan starts, then you can be condescending, looking down on the two states.

Because of the complicated situation in Bingzhou, Liu Zhang had to order the army to slow down its pace, strengthen its vigilance, and guard against possible attacks, and at the same time scatter a large number of spies in all directions to carefully probe the situation around the marching route.

Beigong Yan was not as worried as Liu Zhang, his command was all Qiang cavalry, even if the Hun army came to attack, he couldn't beat it, he still had confidence, 13,000 Qiang cavalry under his leadership ran non-stop to the north, Qi Yuan, Diaoyin, and Gao Nu were left behind one by one.

However, four full days have passed, and what greatly surprised Beigong Yan Dong Zhuo, who originally thought that he would be able to catch up in three days at most, was still missing at the moment, and the only thing he saw in the past four days was only the traces of the army, as for the enemy army, it was half a figure and he didn't find it.

Beigong Yan looked back at the dilapidated city wall with a gloomy face, that is the site of the Great Wall built before Qin unified the world, since Qin unified the world, Qin Shi Huang extended the Great Wall to the north, these Great Walls lost their role in resisting the Xiongnu, and were slowly abandoned, after hundreds of years of wind and rain, most of the Great Wall today only have some vague ruins and a small mound.

Go further, you will go out of the state, into the territory of the Xiongnu, although the same nationality on horseback, but different from the pure nomadism of the Xiongnu, the Qiang people are half ploughing and half pasture, the martial wind is not as good as the Xiongnu, Beigong Yan does not care about the threat of the Xiongnu, there is still a little worry in his heart, first, he belongs to the "away" battle, people and land are born, second, his strength is limited, if the other party comes to tens of thousands of horses, it will undoubtedly pose a huge threat to him.

It's just that the army has already arrived here, and there is no possibility of stopping, Beigong Yan can only hope that Liu Zhang's speed will be faster and not too far away, so that the two armies can support each other, and the security guarantee will be greatly increased.
