It's just that when Gan Ning personally led a small team of people to Nanzheng, before he arrived in Nanzheng, the big battle that happened in Nanzheng had already stopped.

Gan Ning, who was halfway through, was speechless for a while, and it was not good to continue to move forward, so he could only temporarily set up camp in place and continue to send scouts to find out the news of Nanzheng.

On the one hand, it can't be approached directly, after all, there are only 20,000 soldiers and horses around Gan Ning at this time, if Liu Bei's people give up attacking Nanzheng and suddenly aim at Gan Ning, with only 20,000 horses, Gan Ning may not be Guan Yu's opponent.

Therefore, the cautious Gan Ning did not act rashly, but turned back and met with Liu Zheng, Huang Zhong and others again.

Liu Zheng was also very surprised when he saw Gan Ning go and return.

"Xingba, why are you back?"

"How's the situation on Nan Zheng's side?"

Knowing that Gan Ning had returned, there must have been something wrong with Nan Zheng, so Liu Zheng asked Gan Ning directly.

"Your Majesty, it's too late when the news from our spies arrives, and the battle on Nanzheng's side is over!"

Gan Ning was not ambiguous, and directly explained the reason why he returned to Liu Zheng.

Liu Zheng, Huang Zhong and others, after hearing Gan Ning's words, were shocked.

"What, are you going late? Could it be that Nanzheng's battle is over, and Guan Yu's guy defeated Nanzheng so quickly? ”

Huang Zhong was quite surprised when he heard Gan Ning's words, and immediately asked.

Huang Zhong also thought that Nan Zhengcheng had been beaten down by Guan Yu, so he naturally felt extremely excited.

In Huang Zhong's opinion, Nanzheng City is also a county seat after all, and it is not so easy to defeat it, and Zhang Lu in the city still has tens of thousands of troops, according to their previous intelligence, even if Guan Yu can defeat Nanzheng City, it will take at least a few months of hard work.

Stopping the fight so quickly would naturally make Huang Zhong feel incredible.

But Gan Ning immediately shook his head.

"General Huang, how can Guan Yu's men and horses be so powerful!"

"The battle in Nanzheng City has stopped, not because Guan Yu has already defeated Nanzheng, but because they took the initiative to withdraw their troops and surrounded the city, it seems that they are planning to take a protracted war and slowly wear down the soldiers in the city."

Gan Ning told Huang Zhong the news he had found, and for Huang Zhong, as long as Nan Zhengcheng was still there, it didn't matter much.

So, a sigh of relief.

"Guan Yu didn't defeat Nanzheng City, that's okay, at least we weren't too worried, but our spies said before that Ma Chao led a part of the people and defeated some of Liu Zhang's soldiers and horses, so Liu Zhang's soldiers and horses were killed a lot by Ma Chao?"

Liu Zheng also heard Gan Ning's words, and he already had some information, so he was not particularly worried about the situation on Nan Zhengcheng's side at this time.

The only thing he was worried about was whether Liu Zhang and Zhang Lu in Nanzheng City could really block Guan Yu's attack.

However, now it seems that after Guan Yu has carried out a wave of attacks, it seems that he has not made much progress, and Liu Zheng is a little relieved.

"Looking at the current situation, Guan Yu's idea here should be to use the long-term siege to slowly wear down the forces of Nanzheng City, and then force Liu Zhang and Zhang Lu in the city to go out of the city and surrender by themselves."

"Your Majesty, I also think so, it is precisely because the last general felt the thoughts of these people that he did not rush over with the men and horses, but turned back at this time."

"That's really interesting, Guan Yu and Ma Chao are attacking in Hanzhong, if we send soldiers and horses at this time to cut off Guan Yu and Ma Chao's way back to Chang'an, what do you say?"

Liu Zheng suddenly thought of a plan, and suddenly became more and more excited.

At this time, Liu Zheng highlighted this plan, but let Guo Jia, the strategist next to him, also hear it.

When he heard Liu Zheng say that he wanted to cut off Guan Yu and Ma Chao's route back to Chang'an, Guo Jia seemed to think of something immediately, and his eyes lit up.

It seems that there is something to say, but smart people know that they can't steal the limelight from the lord at this time, so even if Guo Jia thought of something, he didn't speak.

It was only after Gan Ning and Huang Zhong looked at Liu Zheng and took the initiative to ask Liu Zheng that they listened to Liu Zheng first.

"Your Majesty, do you have any plans?"

Gan Ning asked Liu Zheng.

Liu Zheng didn't say much, turned around and walked directly to the sand table, and pointed at it with his hand.

"Come and see."

"This is Hanzhong, this is Chang'an, and there should be an interval of five or six hundred miles between them."

Liu Zheng slid back and forth between the two cities of Hanzhong and Chang'an, and showed Gan Ning, Huang Zhong and others the distance.

"Five or six hundred miles away, and there are many mountains, and it is difficult for ordinary soldiers and horses to march, let alone heavy soldiers who transport grain and grass."

During this period of time, Liu Zheng has been paying attention to Zhang Lu, Guan Yu and others in Hanzhong.

Liu Zheng knew that Guan Yu and the others were short of food.

It's just that Guan Yu and these people were not in a hurry to attack the city before, for Liu Zheng, if he didn't fight, the consumption of food would not be large, but once he fought, the situation would be different.

The consumption of grain will become even more huge, at this time, if there is a shortage of grain and grass, the army's morale will be in chaos, and it will inevitably make Guan Yu's tens of thousands of troops stationed near Hanzhong suffer heavy losses.

Liu Zheng and these people may be able to win without a fight.

"From here to Chang'an, how many stations will there be on the road through several counties? What does Guan Yujun's grain transportation rely on? ”

"Once we figure out the news and cut off Guan Yu's grain and grass, the battle of Hanzhong can be declared over."

"What Your Majesty said is extremely true, but I think this idea, it should be difficult to succeed."

After Huang Zhong finished speaking, he immediately questioned Liu Zheng again.

"Where did General Hansheng start with this?"

Liu Zheng was a little curious.

"Your Majesty, from Chang'an to Hanzhong, five or six hundred miles of the road, there must be at least six or seven transit stations in the middle, equipped with a baggage team, the road is difficult, Guan Yu They must also know that it is not easy to transport grain and grass, so they must be very careful, our men and horses, want to cut off Guan Yu's grain route, this difficulty should not be small, once our soldiers and horses appear, Guan Yu's people will definitely be aware."

"It is very likely that our people did not cut off Guan Yu's grain route, but were discovered by Guan Yu's people in advance and surrounded our people, and then they would lose their troops and lose their troops."

Huang Zhong had actually thought about this method early on, but after sending some spies to explore Guan Yu's grain route, Huang Zhong had already given up.
