The next day, Liu Bei personally rode a horse to send Li Su for more than 100 miles, from Nanzheng to Yangping Pass, and to the Western Han River Wharf in Yang'an Pass. Li Su, with hundreds of personal soldiers and several confidant generals and officers, bowed farewell to Liu Bei, and prepared to board the ship and head south:

"I will send you thousands of miles away, and I will have to part. I will just send you here. I will take a boat downstream and arrive at Dianjiang in five or six days."

Liu Bei patted Li Su's hand: "Your brother is careful all the way. I know that you are cautious when facing the battle and will not be in danger, so you are not worried about the war. But you are weak and timid. Now May is about to come. Jiangzhou is six or seven hundred miles south than Nanzheng, so be careful of miasma and fever.

There are a few things here, and I can hold them up, which may be useful - this is all a while ago. Brother Yu considered that you might have to go south to supervise the war and patrol the Qiang and Hu merchants. I heard that this ointment is called mint oil, which was used by merchants from the Great Qin Dynasty in the Western Regions when they crossed the desert to cool down. There is also this wood glue, called camphor, which is obtained by roasting camphor, to avoid the miasma in the south. When you arrive in Dianjiang, you will have the chance to take a bath every day, and you can also add the oil to the soup to cool down."

As he said that, Liu Bei took out a box of incense medicine and handed it to Li Su's servant to pack it.

Li Su was inspired by this material motivation, and his IQ increased temporarily. Before leaving, he reminded Liu Bei more: "Brother was blocked by Huangfu Song and Yuan Shu this time, and he was not allowed to serve the king. It was Huangfu Song first and Yuan Shu later.

But in the future, the princes in the foreign capital contacted my brother and asked me to exert Dayi in the world. My brother refused according to the reason, but he wanted to make a statement in the opposite order, making people think that our army was negotiating with Yuan Shu first and Huangfu Song later."

Liu Bei was slightly stunned, not prepared for this topic. Although he could think about it for a few more minutes with his IQ, since Li Su was right in front of him, Liu Bei was a little lazy, so he asked directly, disdaining to be self-conscious.

"Why is this brother?"

Li Su didn't keep it in a silence: "Being moved by General Cheqi and Cavalry and not sending troops is because he knew that as a relative of the Han Dynasty clan who was a local maid guard, he should not send troops. He refused to allocate food and grass to do so, but did not send troops because he refused to send troops because he did not allow it. The reason for justice should be based on the fact that it should not be first, and should not be later. The wording of foreign negotiations is related to the great reputation, so you must be careful."

If you can't do it, it means that you should do it, but objective conditions do not allow it. If you shouldn't, then don't do it from the motivation level. In the early attempt of something you shouldn't do is of course better than to break the law by knowing the law.

Liu Bei thought for two seconds and quickly thought about this twists and turns.

My heart is so dirty when I engage in diplomacy. I play the word game and fun work here every day.

"Brother Yu understands it, take care of yourself."

...

Six days later, on the fifth day of the fifth month, Li Su, with reinforcements and generals such as Dianwei, arrived at the temporary county seat of Dianjiang County, Brazil.

The prefect Cai Yong, the local civil servants and staff of Brazil, and the generals of the siege on the front line of Diaoyu City all came out to greet them.

Cai Yong was a few months earlier than Li Su. In late spring of March, he took office in Dianjiang. He handled Brazil's civil affairs nearby and comforted the people. However, the local government was like a good place to manage the country.

Cai Yan and Li Sushang had no matchmaker, so in fact, she had just been in love with her secret husband for a winter. After spring, she followed her father to take office and was forced to separate from Li Su for a while. The couple met again for several months after a while, so naturally there was a warm comfort.

The front-line generals in Diaoyu City are currently transferred to play with Yuan Shu and have not returned yet, so the main ones in the front-line are Zhou Tai, Xu Huang, who are under Guan Yu, and Gan Ning, who was officially persuaded to surrender last winter.

Gan Ning was kept in prison after being captured at the end of last summer. Liu Bei knew that as long as he gave him a step in the future, he would seize the handle of Liu Yan's betrayal of the court, proving that Liu Yan was just using Gan Ning and Zhang Lu, then persuading surrender would definitely be a natural result.

So Liu Bei was not in a hurry at that time. He locked Gan Ning for half a year, nor did he let him work hard or torture him. He gave him some books to jail and study and reflect, and then used the usual means of dealing with the gentlemen of the world.

After Cai Yong took office, he respected the wise and wise men personally told Gan Ning about the imperial decree. Liu Yan's rebellious actions, Gan Ning, who had already calmed down from studying, took advantage of the situation and surrendered.

However, in order to clarify the rewards and punishments, Gan Ning had to start with the Qu Junhou in his first surrender, and he could only start with the Qu Junhou to make meritorious service before he was promoted. Moreover, he, the Qu Junhou, was captured and surrendered by the hundreds of thieves at the time, and asked him to re-suppose his old subordinates. He could make him become Qu Junhou, which was considered to be the Qu Junhou "bringing funds into the group."

Anyway, Diaoyu City is still mainly siege, and with the three of them there, there is no problem. The enemy occasionally tried to tentatively reinforcements or grain transport on small scales. Anyone who was on water was repelled by Zhou Tai and Gan Ning; those who were on land were also repelled by Xu Huang.

Therefore, it is not much different whether Guan Yu is there for the time being. When the general attack is really needed in a few months, Guan Yu will have already rushed back.

When Li Su arrived at the front line, he was inevitably inspected Zhou Tai, Xu Huang and Gan Ning. The new official mentioned some precautions and rectified them after taking office.

At the same time, he also had to let the front line spend a few days to rebuild some counterweight catapults according to the drawings he had tinkered at Jianmen Pass. It is not expected that these catapults can really directly and completely break the Diaoyu City, but it is still useful to hit the enemy's morale and further strengthen the blockade.

This job is specifically left to Zhou Taixian, after all, Zhou Tai has the longest with him and the oldest experience.

After explaining the matter, Li Sucai slowly collected feedback from the frontline generals to see if they had any suggestions and actions for the recent siege:

"When General Guan was in charge, how did you siege the city and consume food? Have you tried to find a way to further accelerate the food consumption of the enemy, or just wait like this? Have you taken the initiative to lure the enemy out of the city to harass, or lure the enemy in Jiangzhou to reinforce and fight for the assistance?"

Zhou Tai has the highest position, and he reported sincerely: "I have tried it, but the army in the city cannot lure it out at all. We occasionally clamor to attack the city, shoot the crossbows, and harass them and retreat. No matter how similar the performance is, there will be too many casualties. The enemy in Jiangzhou is not worried about this place at all, and has not come to support for the time being."

Li Su asked carefully and found that their tricks to lure the enemy were also relatively stiff and had nothing new.

Li Su asked, "Did the enemy know that General Guan left the front line? General Guan went to discuss with Yuan Shu to discuss Dong. Has this reason been revealed?"

Zhou Tai was shocked when he heard this. He thought Li Su was testing their confidentiality work in the army, so he quickly denied: "These are confidential things that are not allowed to be discussed. After General Guan left, he had already set up a false banner in the Dianjiang army. How dare he disclose it?"

When Li Su heard this, they felt that they were too honest: "How can you be afraid of leaking? This is a good opportunity to lure the enemy into underestimating the enemy. Although it may not be useful, if you can leak it, it will be leaked - by the way, I can't leak it if I come."

Li Su explained at the end and quickly added a word of care. His arrival was even more scary than Guan Yu's temporary transfer, and maybe it would scare the enemy.

Zhou Tai thought about it, but was still a little worried, confirming: "When General Guan left, he said, 'You can't let the generals of Liu Yan's army know that there were already princes outside to attack Dong', because we have not even let the enemy know that the young emperor who had issued the decree to the general of the Western Expedition to challenge Liu Yan's order.

General Guan once said that this incident would lead to a high morale of Liu Yan's army, which would make Liu Yan and Liu Mao and his son have an excuse to criticize the will, which would be a life-threatening thing - this is something we have to worry about."

Li Su immediately said: "Of course, what Chief Yun said is not without reason, but you can modify and process the information to be leaked, so that the enemy soldiers mistakenly thought that 'Dong Zhuo abolished Emperor and the Shao Emperor, He Jin made the decree to Liu Yan'. It was not that the decree was deposed not long after the decree was issued, so that would be enough? Forget it, I will teach you how to spread rumors..."

Li Su was too lazy to let those guys under his command who were not good at rumoring and spreading words think of words, and directly used the old skills of negotiators to use the leaked scenes and leaked lines, why did the Han army step up its attack, why "if you don't transport grain into the city now, you will be even more lucky in the future, and now is the time to be most relaxed in the defense" and so on.

"Okay, as I said, I will spread rumors. I have organized several attacks from Shuimen these days, causing some dead soldiers to accidentally fall into the water and float to Jishui Beach outside the north wall of Diaoyu City, and were captured by the enemy.

If it doesn't work, launch a few more attacks by land, such as deliberately using our new catapult cart to harass the northeastern section of the city wall, but don't attack forcefully. After a few days, pretend that because the enemy does not dare to leave the city, our main force is lazy and only sends a small number of soldiers to protect the catapult cart, and the army will mainly rest. At that time, the enemy will definitely not be able to calm down. Seeing that there are too few soldiers in the catapult cart position, there will be no ambush around, and they will go out of the city to retaliate. At that time, wouldn't it be better to let them catch one or two cannon prisoners."

For Li Su, there are too many channels to spread fake news, and there are just a few thoughts everywhere.

"Yes, I'll make arrangements now." Zhou Tai took the order and left.

...

In the following days, the Han army changed its previous weak attitude of swallowing water and took several rapid and fierce offensives.

The north section of the east wall of Diaoyu City was originally the only defense zone in Diaoyu City that could be attacked from land. After the Han army built a catapult with a range far exceeding the defenders' defensive weapons, the attack on this section of the city wall was indeed effective.

Xu Huang, with thousands of Hedong soldiers and some of the prisoners of Zhang Lu and Banyan, charged in turn under the cover of more than a dozen catapults, attacked several gaps in the rammed earth city walls, killing and injuring hundreds of enemy soldiers.

Li Su's catapult cart did not stick to the use of single-headed bullets that always smashed the wall, but appropriately matched some gravel bags to form a shotgun effect, specifically killing the vitality of the wall.

Because of unexpected surprise from the new weapons, the Northeast exterior wall was indeed broken.

But this progress is not a decisive breakthrough for completely taking over Diaoyu City. It is nothing more than making Liu Mao give up his peripheral position and shrink the first line of defense to the main peak of Diaoyu Mountain.

Originally, Diaoyu City had a depth of twelve miles from east to west, but after breaking through one road, there was still ten miles of depth, and gave up the two-mile lowland outside.

Once you retreat to the Diaoyu Mountain line, because of the height advantage of the mountains itself, the catapult cart will not be able to smash the city wall two or three hundred steps away. Unless you pull the catapult cart to a very close distance, it will be impossible to "attack the enemy without injury" - the main peak of Diaoyu Mountain is 300 meters above the Jialing River, and the stones will definitely not be thrown up.
