After all, the skills in the game are just games, and there are still a lot of worries when they are moved to actual combat.

Although Diaoyu City is a purely military fortress, and it is mainly a die-hard Dongzhou soldier who betrays the imperial court and allegiance to Liu Yan, there are no innocent civilians.

But in addition to the Dongzhou soldiers, after all, there are thousands of local soldiers in Yizhou, they are not outlaws, but were driven into the city by Li Su after the defeat before, and it is not to mention the diehard loyalty of Liu Yan, the anti-thief, may just be coerced. Li Su was entertained with rabbit meat before, and he also really rebelled against some wavering people and continued to lurk.

Moreover, the plague is not easy to control, and it has no technical content, so it is not good to be imitated by the enemy, Li Su finally gave up the tactics of the "Fortress" game.

However, inspired by this, Li Su thought of another way: since there are still potential moles at both ends of the first rat in the city, can you try to poison Liu Mao?

Chemical poisons are easy to be detected, but they are only food-borne bacteria typhoid fever or something, and there is still some hope for killing the main general, so that people who are willing to poison but are afraid of not being able to avoid the test can succeed, they only need to be responsible for collecting ingredients.

Requests and information for poisoning can be written on a wooden plank, and on an appropriate day, when it is confirmed that a mole has come to draw water or catch fish, the plank can be thrown to the opposite shore by catapult. If the traitor picks it up, if you have the courage to do it, then it's best, if you don't have the courage to do it, it will be a waste of a ploy and continue to surround it for a year.

Moreover, the winning rate of this kind of thing has a lot to do with personal health. If he was replaced by an enemy general with a very strong physique and a very good physique, Li Su would not be sure how effective this move would be.

But Liu Mao obviously belongs to the son and brother who are very weak in the history books, and he died of illness in 192 or 193 at the latest, and even the death of his father Liu Yan was because his son died of illness before him, and the white-haired person sent the black-haired person and suffered a big blow. Such a virtual person who could not live for more than three years may die with a little strong gastroenteritis, so that non-fatal infectious diseases can kill him.

Of course, it cannot be ruled out that Liu Mao's illness and death in history were because the newly married Wu was too good-looking, and he died suddenly due to excessive lust, which can only be verified by the historical truth.

Thinking of this, Li Su thought of a little trouble again - so far, they have also blocked the news that Wu Kuang, Wu Ban, Wu Lan and others have surrendered to Liu Bei, and on any occasion to prove the effectiveness of Liu Beijun's holy decree, only Cai Yong came forward to shout circumstantial evidence, in order to prevent Wu Yi from being killed.

But now it seems that according to the previous intelligence of the commanders of the enemy army, Wu Yi was taken by Liu Mao as a quasi-brother-in-law to defend Diaoyu City.

If Liu Mao is poisoned in the fish he eats, it is also possible that a small range of people around him will cause infectious diseases, if Liu Bei still marries Wu in the future, and Wu Yi is also poisoned, it will not be good-looking.

Li Su had to keep one hand and postpone poisoning Liu Mao, but had to hit the morale of a wave of rebels with another kick, stab this layer of window paper, and let Liu Mao drive Wu Yi away first.

Li Su thought about it, found Wu Ban, who was with the army, and asked a question.

Wu Ban followed his father Wu Kuang into Sichuan, and has not made an inch of success so far. Wu Kuang stayed on the front line of Jiameng, in case he could listen to it at any time, and Wu Ban came to the Dianjiang side. When he was summoned by Li Su, he was also eager to try and thought that he had a chance to perform.

"What are the military orders of Zhonglang?"

Li Su waved his hand: "It's nothing, ask you a few words of gossip, your cousin, after growing up, have you seen it?" How old were you when you last saw her? How's it looking? ”

Wu Ban was stunned: "Zhonglang is not ...... to the clan sister"

Li Su: "What are you thinking, I just want to know, if Liu Mao knew that you and Ling Zun had followed General Zhengxi, would he be willing to kill his wife Mingzhi, and then kill his brother-in-law as well-I have always wanted to keep the news that you are on the same road with General Zhengxi, but now there is no way to keep it secret, I have to reveal it, and by the way, I will surrender and hit the morale of a wave of defenders." ”

Wu Ban breathed a sigh of relief, and then packed the ticket with confidence: "Although Zhonglang can rest assured, although the clan sister is not unparalleled in the world, it can be regarded as a beautiful country, not to mention the uncle's family, Liu Mao will not be angry." ”

Li Su smiled: "This is what you said, in the future, if your cousin is really killed by Liu Mao, don't blame me." ”

……

After knowing this, Li Su temporarily inserted the pre-plan the next day.

He sent people to the Diaoyu City again, set up a catapult to attack the city, and after a fight, he took advantage of the enemy's attention to come over, and let Wu Ban shout again outside the enemy's range.

"Brother! I am Wu Ban, my father, Zuo Zhonglang, will be suspicious of the imperial court and reduced to an infantry captain because of your and your sister. My father also asked to go out of Beijing and announce the return of Liu Yan with Cai Gong!

It was General Rende who conquered the west, and he was afraid that you would be implicated by us, so he never let my father come forward. But how can we not think of repaying the court? We have been following General Zhengxi for more than half a year, and today you have to blame the little brother.

Liu Mao! Don't be obsessed with it anymore! We Li Zhonglang have countless ways to take Diaoyu City, and sooner or later we can take it, but we just don't want to kill more! If you betray the imperial court, we can also help you cover it up, as long as you put down your weapons now, you can still be an idle official with 2,000 stones in Liu Yan's rank, and you can live in another state! ”

Wu Ban's persuasion to surrender instantly set off another uproar in the city, and someone immediately notified Liu Mao, and Liu Mao immediately brought Wu Yi over to confront him face to face.

"The person down there is really your cousin? Your uncle also followed Liu Bei? Liu Mao's face turned pale.

Wu Yi looked at it from a distance in a panic, and then discerned the voice of the shouting, his face was like ashes for a while, and he didn't know how to justify: "That person ...... It is indeed the clan brother Wu Ban, and what he said about his uncle is not bad. But I, I don't know, and I haven't betrayed the son, if the son can't be compatible, pray that for the sake of the sister, I will be stripped of my military power, and sent back to Jiangzhou in the starry night. ”

Wu Yi was in a hurry to protect himself and was willing to hand over his military power.

Liu Mao thought about it, Wu Yi himself really did not betray, if he dealt with it directly, it would be difficult for his fiancée to explain, and I am afraid that morale will be even lower.

He could only push the boat down the river and chose to send Wu Yi away.

……

However, Wu Yi did not go smoothly after all.

The boat escorting him didn't go far before it was intercepted by Gan Ning, and even at night, it couldn't escape Gan Ning's sense of smell under the cover of night.

After Wu Yi was captured and his guards were killed, Li Su easily obtained more detailed information about the city, including the cycle of each army's change of defense, and the schedule of daily rotational logistics tasks.

For example, which day is the turn of the army to draw water and fish to subsidize military supplies.

even knew that Liu Maojun had indeed had a shortage of firewood and grass, and some of the vegetables that could be eaten raw in summer would be eaten raw.

Li Su checked the schedule of the prisoners of war who had been successfully persuaded and returned to the undercover service, as well as the schedule dates of those who had not yet been exposed, and quickly calculated when to release the fish upstream and how to throw the plank to report the news.

No one is willing to do it, so you should continue to prepare for the next move.

In addition, since it is possible to kill Liu Mao, a die-hard element, Li Su also began to want to threaten Liu Yan's backhand. He knew that Liu Yan's eldest son and second son were still Jingguan and could not leave Luoyang, but the youngest son Liu Zhang now seemed to have fled south to Nanyang, which was controlled by Yuan Shu, because of the butterfly effect.

In the future, maybe you can get some quid pro quo for Dong, and get Liu Zhang over as a spare tire hostage to prepare for further plans.

The fish and the planks were put away, and there was no movement in the city for three or five days. Li Su didn't know if they dared to do it, or if they did it.

But no matter whether they do it or not, Li Su's other siege and food consumption plans will continue to be implemented, which can only be regarded as an unexpected joy.

It's just that the summer is too hot, even if Li Su asked Xu Huang to pay attention to the epidemic in the army, and repeatedly took care that drinking water must be boiled and eating fish must be cooked, although no one died in Xu Huang's camp, there were still many people who had diarrhea and collapsed and temporarily lost their combat effectiveness.

This subtropical disease is not adapted to the soil and water, and it is estimated that July, the hottest month, is not good.

Li Suzong had more plans, but he was constrained by the objective unfavorable conditions of the northern army going south, so he had to rest for the time being, and wait until July.

In this way, the two armies made a truce to escape the summer, Li Su boiled cold boiled water and bathed every day, paid great attention to personal hygiene, and even women did not dare to touch it, and they were very well maintained and spent July tremblingly.

However, one day in early August, Li Su suddenly got a piece of good news—just a sign of good news, to be exact.

Because he found that the defending army in Diaoyu City was obviously shaken and confused.

After another two or three days, another wave of troops in the city took advantage of the opportunity to draw water and fish, and stole small boats to cross the river and surrender.

"Why did you come down? Could it be a fraud? When Zhou Tai caught these surrenderers, he didn't dare to believe it.

"We want to see Li Zhonglang! We have made meritorious contributions, Li Zhonglang can't deny it, Liu Mao died, he died of eating bad things and diarrhea! The people in the city are now panicked, and if you attack them twice, they will definitely surrender! ”

The soldiers who came to surrender tried their best to show their merits, emphasizing that they had come to lead the way with repentance.

Zhou Tai cautiously asked the soldiers to thoroughly wash all these guys and change their clothes before allowing them to go to Li Su to report the good news - of course, Zhou Tai himself would monitor the whole process to prevent assassination.

Li Su heard the news, and Huo Erqi said: "Liu Mao is really dead?" When was poisoned? How long have you been sick and when did you die? ”

The surrenderer truthfully confessed: "I ate it in July 10...... After eating the fish we brought back, I still made yusheng, and after five or six days, I vomited and diarrhea, and after less than ten days of ejaculation, it was ineffective to seek medical treatment. There were dozens of other soldiers and generals around him, who were infected to varying degrees, but only a dozen died of illness. ”

Li Sumo rubbed his fists a few times and ordered: "Attack the city immediately!" If he hadn't died, he would definitely have been able to force him to show up and stabilize the morale of the army. ”

Zhou Tai gave up the order and immediately went down to prepare: "Obey!" ”

In the evening of the same day, the Han army launched another fierce siege, and the whole process of preaching its own logistical advantages, constantly shouting to persuade surrender.

The morale and defensive strength of the defenders really suffered a lot of losses, and the left and right sides resisted for an afternoon, and two parapet walls were broken through one after another.

The defenders in the city began to surrender in large numbers, and in the end, only Liu Bi, who was guarding the top of Diaoyu Mountain, was left behind, fearing that he would not be pardoned, and continued to resist with the last most diehard Dongzhou soldiers.

But the key points in the city have been taken, the granary has also been taken away from several places, and the cottage on the top of a commanding hill can no longer make waves.
