Liu Biao finally made up his mind to concentrate on attacking Yangzhou, although he was only forced to do it. After all, who is not greedy for this big fat piece in Yuzhou?

Chenliu County, Yanzhou.

"Hehe, in the past, Ben Chu and Xuande used to be hostile to each other, and they planned to woo me. I can't imagine that after so many years, the old thing will repeat itself......" Cao Cao chuckled as he looked at the two letters in his hand.

"Lord, but King Qi and Duke Yan both plan to form an alliance with Lord?" Hearing this, Xun Yu on the side asked respectfully.

"Yes, I originally planned to form an alliance with me to fight against Xuande, and promised that as long as Xuande was defeated, then the entire Yuzhou would be handed over to me. As for Xuande's meaning, it is almost the same, but he plans to hand over the western part of Jizhou and Youzhou to me......" Cao Cao casually put the two letters aside, looked around at everyone and smiled.

"Humph! This King Qi has a good calculation! If you hand over the western part of the country to the lord, isn't that going to use the lord as a shield?! Xun You snorted coldly when he heard this. But as soon as he finished speaking, he hurriedly apologized to Cao Cao and said, "My subordinates have lost their words, and I ask the lord to forgive me." ”

"Alas...... Now, I don't have much hope...... The world will inevitably return to the Warring States Period after Zikang captures Chang'an. Cao Cao sighed when he heard this.

Hearing this, everyone was silent, although many people have seen this matter, but it is one thing to see it, and it is another thing to say it.

After a long while, Cheng Yu asked in a meaningful tone, "Since the matter has come to this, I don't know what the lord is planning?" ”

"Haha, naturally, before Zikang captured Chang'an, he would get the greatest benefits! Although I, Cao Mengde, am not talented, but except for my Emperor of the Han Dynasty, I don't intend to bow down to anyone! Cao Cao laughed when he heard this.

"We will definitely swear allegiance to the lord and help the lord!" Hearing this, Xun You and the others said in unison.

"Hmm...... So, let's talk about what you think~" Cao Cao nodded with satisfaction when he heard this, and then looked at everyone and asked.

"Lord Gong, my subordinates think that they should unite with Yan Gong to fight against King Qi!" Xun You said.

"The lord and the king of Qi had a grudge against Xuzhou in the past, and if they united with the king of Qi, even if they defeated the Duke of Yan, the territory would not be easy to divide at that time. In this case, it is better to unite with the lord to have the old Yan Gong, and when the lord sits on the land of Yanzhou, Yuzhou, and Xuzhou, he will have the power to fight in any case! Xun You said respectfully.

"And what if you go south at the beginning?" Cao Cao asked when he heard this.

"Don't worry, by the time the lord defeats King Qi, I'm afraid that Duke Zhao will already occupy Chang'an. At that time, the lord could unite with Yan Gong to fight against Zhao Gong, and it was impossible for Yan Gong to disagree. Cheng Yu opened his mouth to explain.

"Yes, and if you unite with the King of Qi, even if you defeat the Duke of Yan, then the Lord will be the same as the Three Kingdoms of Zhao, Wei and Han during the Warring States Period, the King of Qi will hide behind the Lord to recuperate, and the Lord Duke must face the army of the Duke of Zhao." Jia Xu also agreed.

The three strategists had such a unified opinion, which Cao Cao did not expect, but he was obviously happy to see this situation. Because the words of the three of them are also his thoughts.

made a decision, Cao Cao immediately sent someone to communicate with Yuan Shao, and Yuan Shao was naturally overjoyed about this. He immediately ordered his troops to fight against Liu Bei with Cao Cao.

The news here naturally couldn't be hidden, and soon Liu Bei learned the news.

"It's really disappointing...... Liu Bei sighed helplessly.

"Didn't my father already anticipate it?" Zhuge Liang on the side chuckled, "If the situation is very clear today, it is not surprising that the Zheng Guild has made such a choice. ”

"Yes, Meng De is both civil and military, and he is assisted by many talented people under his command, how can he not see through the current situation?" Liu Bei shook his head, then his expression was solemn, and he ordered in a deep voice, "Pass the order, let Yide and Ziyi be prepared, and you must defend Qingzhou and Yuzhou for me!" At the same time, all parts of Xuzhou should be well armed and ready to send troops to support at any time! ”

Obviously, Liu Bei had already expected such a thing, but he still wanted to give it a try, what if Cao Cao agreed? And now in this situation, he is naturally not without a way to deal with it. Although this method sounds a little frustrating.

"Zikang, I hope you don't disappoint me......" Liu Bei looked at the West and thought to himself.

Yes, Liu Bei's countermeasure is Li Yi, as long as Li Yi can capture Chang'an before Cao Cao and Yuan Shao defeat him, then the situation will naturally change.

And in this regard, Cao Cao and Yuan Shao are naturally very clear, how can they let Liu Bei get his wish?

At the beginning of October, Cao Cao sent 80,000 troops to attack Peiguo, which was defended by Tai Shici, and Yuan Shao gathered an army of 150,000 and slaughtered Qingzhou. As for excuses? Liu Bei is a prince and king, but the territory under his rule spans the four prefectures of Qing, Xu, Henan, and Yang, so the excuse is not too easy to find. Not to mention that Yuan Shao is still under the banner of the emperor, although no one recognizes this emperor at all.

At the same time, in Yangzhou, Yuan Shu and Liu Biao also fought fiercely, and launched several fierce battles around Lujiang, Danyang, and Yuzhang. Among them, Liu Biao not only sent Cai Mao, Huang Zu, Huang Zhong and other generals, but also mobilized tens of thousands of troops. That appearance has the meaning of a decisive battle with Yuan Shu.

"It's really lively...... Li Yi looked at the information sent from all over the place, shook his head and sighed lightly.

"Come to think of it, it's because they have already felt the pressure brought by the lord, so they have to expand their strength as soon as possible......" Xu Shu on the side said with a smile.

"That's right, if they don't expand their power as soon as possible, then after the lord captures Chang'an, I'm afraid they won't have the strength to compete with the lord for the world anymore." Hearing this, Fa Zheng hurriedly opened his mouth and agreed.

"Hehe, how can it be that simple? Won't they form an alliance to crusade against me just like the Six Kingdoms did in the past? Li Yi shook his head and smiled when he heard this.

"It's a possibility, but as long as it's a coalition force, it's rare to be able to sustain it for a long time. This is true both during the Warring States period in the past and when Dong Zhuo was crusaded before. Xu Shu chuckled when he heard this.

"Then do you think it's better for me to step up the capture of Chang'an, or slowly besiege the city and let the Kanto side fight more fiercely?" Hearing this, Li Yi looked at everyone with a smile and asked.

"Didn't the lord have a plan in his heart?" Xu Shu and the others laughed when they heard this. It seems that the complicated situation in Kanto does not feel tense at all? Maybe it's because it's too smooth? So obedient that they feel that there is no enemy in the whole world at all?

But then again, it is precisely because Li Yi's power is too strong that Xu Shu and others are so confident. After all, Li Yi's power has grown rapidly over the years, which is obvious to all. When other forces were still desperately fighting to expand their territory, Li Yi was already sitting on most of the annexed states and divisions to recuperate.

Moreover, since Jizhou Wei County fell into the hands of Li Yi, he doesn't know how many years he has been recuperating. Although it occupies only the west of Ye County, Ye County, as the seat of the former Jizhou Thorn History, is the most developed area in the entire Jizhou, and who can underestimate this place?

In early October, what Li Yi had been waiting for finally arrived in Chang'an.

"Lord, with these stone paints, can you really break through Chang'an?" Lu Wen looked at the black slimy thing in front of her curiously, and asked with a puzzled voice.

"Lingqi, what do you say this stone paint does?" When Li Yi heard this, he asked instead of answering.

"Lighting a fire, many people use it to make oil lamps or ink." Lu Wen said without thinking, but after speaking, she showed a look of doubt and said, "But this thing sometimes burns with thick smoke, and it seems to be poisonous, so it needs to be treated with a special method before it can be used." After speaking, Lu Wen seemed to react, and looked at Li Yi with some surprise, "Isn't the lord planning to attack with fire?" ”

"Not bad." Li Yi nodded and said, "What do you think will happen if you throw these stone paints on the city wall or city gate, and then shoot them with fire arrows?" ”

"This ...... Is it so easy to succeed if it's just a fire attack? Lu Wen asked in disbelief.

"Who knows? I have to give it a try. Li Yi said with a smile.

This kind of stone lacquer, in fact, is the crude oil of petroleum, which was first recorded in the Book of Changes, "There is fire in Ze, and there is fire in Ze." In the Han Dynasty, the [Book of Han] written by Ban Gu also recorded, "Dingyang and Gaonu have confused water, and fat can be dipped in." ”

The reason why Li Yi discovered oil is because of this sentence. In the past, Li Yi had no choice but to settle in Hanoi, Taiyuan and other places because he had collected too many displaced people, so naturally, he hit the idea to the sparsely populated three counties of Shuofang, Shangjun and Xihe.

Although there are not many deserts or mountains in these three places, at least the two counties of Shangjun and Xihe still have a lot of land that can be cultivated. However, in order to save costs, Li Yi also deliberately checked various records about the two places to see if there were any minerals or the like. And it was at this time that Li Yi saw the record in the [Book of Han] and immediately became interested.

The so-called fat can be dipped means that the water there not only has oil, but even sticky can be used to dip a pen to write. In Li Yi's memory, there are not many things with such characteristics.

And when he arrived at the place, Li Yi recognized this thing at a glance as the oil that made all the car owners extremely indignant in later generations. After all, with its rich flavor and dark color, Li Yi didn't know what else could it be besides oil.

However, as Lu Wen said, the use value of this thing in this era is not too great, after all, there are too many better alternatives. But as a traverser, although Li Yi couldn't think of any effect of this thing for the time being, he still sent some homeless people to be responsible for mining these things, maybe when it will become useful?

Immediately, Li Yi summoned the people from the Ministry of Works, pointed to the jar containing oil in front of him, and said, "I want to throw these jars with stone paint onto the city wall with a trebuchet, and you can think of a way." ”

Hearing this, these craftsmen did not ask much, and directly stepped forward and began to estimate the weight and shape of their jars. Then he took out a pen and paper and an abacus and began to calculate. Yes, it's computing, after all, it's a projectile, and all kinds of calculations can be quite cumbersome, especially in this era when there are no computers. This is also why trebuchets are generally only powerful when used on a large scale, and when used, if there are troops that cooperate with the attack, they will definitely be very far away from the attack range of the trebuchet. Because today's trebuchets can't aim precisely at all, they can only attack the target they want to attack if they have a wide area of coverage.

"Don't worry, you can take it back and calculate it, and you can even find a secret place to test. But remember, after the calculations are over, make sure to make sure that you can throw it on the walls and at the gates! Li Yi looked at everyone and smiled.

"Please rest assured Zhao Gong!"

Three days later.

"Your Majesty! Dowager! The enemy forces surrounded outside the east gate began to retreat. Huang Er reported respectfully.

"Huh? Retreated? And what about the other enemy forces? Ma Chao looked at Huang Er suspiciously and asked.

"There's no movement."

"Maybe Li Zikang has researched a new siege machine?" Zhang Ning muttered, "It is said that Li Zikang has set up a special place called the Ministry of Industry, and a large number of skilled craftsmen have gathered in it to conduct research on various instruments. ”

"Humph! What if it is researched? Ma Chao snorted coldly when he heard this, he didn't have much of a good impression of these siege equipment, in his opinion, fighting a war should be fought with a famous sword and a famous gun. However, although he said so, Ma Chao did not dare to be careless. After all, although the building car was finally destroyed by them, it really scared him a lot.

Saying that, Ma Chao got up and said to Zhang Ning, "Queen Mother, Erchen will go to the city wall to take a look first." ”

"Well, go ahead, be careful." Zhang Ning instructed when he heard this, and then smiled at Wang Yi and said, "Junqi should also go and have a look." ”

"No!"

Soon, Ma Chao, Wang Yi and others came to the city wall of the East Gate, looking in the direction of the enemy, a mocking smile suddenly appeared on the corner of Ma Chao's mouth, "It seems that this Li Zikang finally can't bear it anymore and is ready to attack again." ”

No wonder he thought so, because now the Li army under the city had lifted the siege of the east gate and was escorting dozens of catapults to the north and south sides of the east gate. At the same time, there were countless Li Jun soldiers, protecting dozens of wells and slowly moving forward.

"Your Majesty, don't be careless, if Li Yi is ready to attack, it makes no sense that only the East Gate will act. And looking at the posture, it seems that the enemy army does not intend to approach the city wall......" Wang Yi reminded as he looked outside the city with a serious expression.

"Well......" Hearing this, Ma Chao didn't say much, just silently watched Li Jun's actions outside the city.

After a while, the catapult and the well stop and "prepare to dodge the flying rocks and beware of the arrows!" Seeing this, Huang Er immediately ordered. But in fact, there was no need for him to give an order, and the soldiers of the Taiping Army, who had already experienced all this, had already taken precautions when they saw the catapult and the well.

And at this time, Li Jun's catapult moved.
