"Did you bring back that kind of crop that yields hundreds of stones per mu?" When Cao Cao heard about the grain yielding hundreds of stones per mu, his eyes almost popped out. He Cao Cao is just short of food, if there is that potato, is he Cao Cao still short of food?

The spy said with an ugly face: "Although there are a lot of potatoes, they are very expensive, and we can't afford them." "It's true, when Liu Zhang sent them back, they basically stripped everything except their clothes.

Cao Cao asked with a deep face, "Liu Zhang, where are there a lot of ways to refine steel?" "Since the potatoes are easy to handle, Cao Cao is turning around. But he still cares very much about the output of steel.

The spy nodded hurriedly and said, "Liu Zhang has a lot of large-scale steelmaking workshops in Hanzhong, and they have a lot of convenient cars there. There is no need for horses at all, and as long as one person can easily transport grain of 100 stones. The spies were puzzled by the convenience of the tricycle, which seemed simple but could be moved so easily.

Cao Cao was speechless for a long time, but Xun Yu on the side asked, "How many troops does Liu Zhang have in Chang'an?" And what about the two queens? Xun Yu was thinking about other things, and he didn't have time to think about those policy matters now.

The spy thought for a moment and said, "I heard that the permanent troops in Chang'an are only tens of thousands, but those soldiers train every day and don't work at all. Listening to the people there, those soldiers are professional soldiers, and they are definitely the best of the best soldiers. The queen lived alone and was not in Liu Zhang's mansion. Since Liu Zhang came back from Nanyang, it seems that he went to Xiliang not long after. "There is no need to inquire about these messages, basically everyone knows about them.

Xun Yu frowned and asked, "Go to Xiliang?" What to do in Xiliang? This really made Xun Yu wonder. Looking at the spy and saying that he didn't know, Xun Yu sighed and said, "Lord, I'm afraid we've been fooled." Liu Zhang may not be powerful, but Liu Zhang definitely has a world-class talent comparable to Guan Zhong around him, and even more powerful than those people. Looking at all of the above, Liu Zhang is not in Chang'an, Chang'an is constantly changing, which is enough to show that the characters who preside over Chang'an are really terrible. Then Liu Zhang's side has generals such as Xu Huang, Wu Yi, and Zhang Ren, and the strategists are Fa Zheng, Li Ru, and others. Xun Yu reacted quickly, even if Liu Zhang was not powerful, but Liu Zhang's group of subordinates were too powerful.

Cheng Yu also came out and said: "It seems that the lord has also discussed asking for those two women, I'm afraid Liu Zhang is just taking advantage of the trend." This time, I'm afraid we will be calculated again, Liu Zhang has hundreds of thousands of troops, but it gives people a feeling of weakness, this is to paralyze us. "By the time I wake up, I'm afraid it'll be too late.

Cao Cao has been silent, and he is not stupid. When Xun Yu first said it, he had already reflected it. But what can he do now? How can Liu Zhang's subordinates have such powerful characters? Why would that kind of character be in a place like Nishikawa? I really can't figure it out, the step Liu Zhang took seems to be very purposeful, but he still can't understand the two women he asked for Cao Cao.

"It is impossible for us to make peace with Yuan Shaoyan at this moment, that Yan Liangwen has been provoked several times, and he has the upper hand. If we speak and Yuan Shao at this time, he will only feel that we are afraid of him, and he will inevitably continue to attack us. Secondly, I know Yuan Shao, and he also understands me. Yuan Shao must think that I am playing some kind of conspiracy again, and he will never believe that Liu Zhang is stronger than him. Speaking of this, Cao Cao felt a burst of irritability in his heart, and all the joy he had because of getting Guan Yu was lost.

"Liu Zhang, is there anything that is particularly powerful about blowing up ships?" Xun Yu thought of Liu Zhang's bombing of Sun Ce's boat, and they still didn't know what it was.

The spy thought for a moment and said, "There have been rumors in Chang'an, as if that thing is called gunpowder, and its power is earth-shattering. But no one has ever seen what that kind of thing is. "The recipe for gunpowder and the place where it is produced are absolutely safe, and they can't even get the technology to make paper and weave, let alone gunpowder.

Cao Cao pondered: "Gunpowder? This thing is earth-shattering? It's also troublesome to want to make it, and even if Liu Zhang has it, I'm afraid it won't be much. This kind of thing can only be used as a curiosity, not as a common use. We should focus more on potatoes and steel, which can greatly enhance our strength. "Potatoes ensure food, steel ensures combat effectiveness. Cao Cao can imitate Liu Zhang little by little, but everything is nonsense without food.

Cheng Yu came out and said: "Potatoes can be bought with only money, which is definitely not difficult." But the technology of steel, I'm afraid we can't get it. "Potatoes only cost money, according to the spies, but how do you get steel?

Cao Cao pondered and said: "Send merchants to buy potatoes first, and if the steel is not good, buy steel weapons from Liu Zhang, and send a group of blacksmiths into Chang'an, if you can, you must get this technology." "This is definitely something that Cao Cao covets.

The spy looked at Cao Cao and said: "There is another thing called electric light in Chang'an, the lord, which can illuminate the night as if it were day every night, and there are many electric lights on Chang'an Street. Everything else was fine, but the electric light was the one that shocked the spies.

Cao Cao was stunned for a moment: "Shine? At night? Lamp? All on the streets of Chang'an? "Cao Cao really doesn't understand, the previous things can be understood, but what's the use of this kind of thing?

The spy thought for a long time before saying, "...... for lighting at night" seems to be probably the only function??

Cao Cao laughed: "Useless things are far less useful than potatoes." "If it's just lighting, then when you're rich, potatoes and steel are the priority.

Seeing that the spy didn't say anything, Cao Cao asked again, "What different weapons does Liu Zhang have?" Also, how did a lot of you go and come back, you two? "The spies sent out three batches, each batch of more than ten people, but this little bit of the situation is a bit wrong.

He said tremblingly: "I didn't find any different weapons except for the steel weapons, and all the others were arrested." The lord and we were also put back, and when we came back, Liu Zhang saw us and asked if we were spies. The little ones all said yes, then Liu Zhang said that since this is the case, you should go back, and tell the lord what you know, what you see, and what you hear. "The two of them don't dare to hide it at all, if they hide the news today and leak the news of the next day, they will definitely die.

At this time, Cao Cao and everyone were not happy when they heard it, and if they caught Liu Zhang's spies, they would definitely ask some questions. But Liu Zhang didn't seem to beat them, so he let them go back so easily? After going through so many things, Cao Cao was a little scared, could it be some kind of conspiracy? This Cao Cao has been a little fooled by those people around Liu Zhang recently, and he always feels that the other party is calculating him all the time.

Finally, Cao Cao said in a deep voice: "The top priority is to buy potatoes, and as for the steel, put it aside for the time being." At present, we are attacking Yuan Shao with all our might, and Liu Zhang will not move there for the time being. After defeating Yuan Shao, we are slowly dealing with Liu Zhang. "One is imminent, and the other is buffer.

In fact, Liu Zhang knew that it was impossible to hide the matter of potatoes. As long as they start eating here, Cao Cao and the others know that it is only a matter of time, and Liu Zhang really can't help this. However, this is a good thing for Liu Zhang, it is best for Cao Cao and Yuan Shao to steal some and go back to plant a large area. In this way, the people will not starve to death, which is also a good thing. lest it be controlled by the gate valve, and ordinary people still can't afford it.

In this way, Cao Cao will feel that it is not easy for him to get, and he will inevitably plant a large area, and Liu Zhang of the province will have to spend effort to promote. After all, what you give yourself, others may not cherish, but what you can hide, others will dig out their hearts to get.

Cao Cao actively prepared for a big battle with Yuan Shao, and the two had been holding each other in Guandu for several months. This situation of wasting money and food in vain, without fighting and not retreating, made Cao Cao very worried, but Yuan Shao was even more worried. Compared with Cao Cao's people, Yuan Shao has much more than Cao Cao. The daily eating, drinking, and Lazar are enough to make Yuan Shao feel distressed, and the list of thieves has been sent out for a long time, but this situation of no war and no peace makes Yuan Shao's subordinates unable to sit still.

Tian Feng felt that it was best to hold each other like this, because Yuan Shao had a lot of money and food, and this kind of soft means could drag Cao Cao to death. If Yuan Shao felt powerless, then Cao Cao would inevitably be even more overwhelmed. By the time his lord can't hold on, then Cao Cao will definitely be dead. At that time, the army was dispatched, and Cao Cao could only be defeated.

Although he was demoted, this person was loyal to Yuan Shao and didn't have too many ideas. Every day, he and Tian Feng drank and discussed the military, and both of them felt very good about the current situation. Cao Cao is a hero, and he can't be in a hurry, and such a little advantage is definitely better than the whole army going out to do a hard job. That kind of practice is just a trick to kill a thousand enemies, and it is not worth mentioning.

"Brother Yuan Hao, now that Cao Jun and our army are deadlocked, this situation is very good." Yuan Shao didn't listen to what he said, and forcibly ordered Yan Liangwei to attack the white horse, and now he is a little frustrated. Although it is easy for them to cross the river in the situation, this kind of thing is absolutely not suitable for rushing Yanjin to think about crossing the river before it is taken, it is better to send troops to cross the river and occupy Yanjin to cross the river. Don't use natural risks, it's for short-sightedness.

Both men believed that it was best to hold on without a fight and constantly harass the enemy. Xu You's plan to suggest a surprise attack was delayed, and the two of them felt fortunate. Steady and steady is the fundamental, once the surprise attack fails, it will not increase the morale of the enemy, and let the morale of your own side. It's not wise to do that......
