And the Tang Dynasty did not have so many troubles.
But now that he is back, not only is the city covered with snow, this rebellion has also pushed the Tang royal family into the center of the storm.
The slogan Li Ke used this time was to clear the emperor's side, kill Li Chengqian, and vent evil spirits for the people of the world.
Of course, he said it was for the common people, but in reality it was just for those aristocratic families and himself.
After all, the people knew very well how Li Chengqian treated the people.
After sending Li Yuan and his party to Chang'an City, Li Chengqian did not stay much longer.
He immediately returned to the ferry without stopping, took the boat and continued northward to Longyou Road.
At the beginning, his plan was to let the Liangzhou army directly attack Yizhou after Li Ke left Shu.
Unfortunately, things didn't go as he wished.
Even though Gao Zhi was entangled with the advance team of the Shu army, Li Ke was as stable as Mount Tai and still sat in command in Yizhou.
This also resulted in Li Chengqian having to change his thinking.
Of course, his trip back to Chang'an City cannot be in vain.
He also took the opportunity to bring out Changsun Chong and Cheng Hualiang, who were idle at home.
These two people have spent the longest time with him and have gone on the most expeditions together, so they naturally have a tacit understanding.
While on the boat.
The three of them began to discuss the next tactics.
While on the road, Li Chengqian asked someone to make a simulated sand table based on the map.
At this moment, the three of them were also surrounding the sand table, each trying to figure out the next attack route.
"You two shouldn't need to stress the situation in Shu."
Li Chengqian looked directly at the two of them and asked: "Right now, I just want to ask you, where should we store our food, grass and baggage?"
After hearing this, Changsun Chong and Cheng Hualiang said in unison: "Hanzhong."
At this moment, both of them couldn't help but be stunned for a moment.
Then, the two looked at each other again.
Changsun Chong was the first to speak: "Hanzhong is about the distance from Chang'an In the near future, our logistics team can directly depart from Chang'an to supply our team."
"In this way, we can not only let the imperial court help us guard our supply lines, but also provide better protection for the soldiers."
Hearing this, Cheng Hualiang also nodded.
He said: "This guy is right. I, Xiao Cheng, also think that Hanzhong is the most appropriate place. At least we only need to fight on the front line. The imperial court will help us later, so we don't have to worry about this matter.
"
What they said does make sense.
From the map, Hanzhong is located between Chang'an and Yizhou.
Moreover, it is located at the entrance of Shu Road.
If the army advances via the Shu Road, it would be safest to hoard the grain, grass and baggage in Hanzhong.
But after hearing what the two said, Li Chengqian still had a solemn expression.
He looked up at the two of them and said, "You know what is going on in Hanzhong, I know it too, but Li Ke also knows it."
"If nothing else, let's talk about what it would be like if you two were in Li Ke's position."
"When you know that our army will put all the food, grass and baggage in Hanzhong, will you sit back and ignore it?"
They know that Hanzhong is important, doesn’t Li Ke know that?
As I said before, Li Ke has always been said to be the most like him among Li Shimin's sons.
Regardless of his literary skills or military strategy, Li Ke is very similar to Li Shimin when he was young.
And his abilities on the battlefield are naturally not inferior to those of the young Li Shimin.
He must have thought that if the Tang Dynasty went on a southern expedition, Hanzhong would definitely become a storage place for grain, grass and baggage.
For a person with Li Ke's kind of mind, how could he not make a fuss out of this?
"Hanzhong is among the mountains."
"If Li Ke wants to attack Hanzhong by surprise, the only way he can take is the Shu Road."
"And the Shu Road is in our army.
How could he come out under such a fierce attack?"
Cheng Huailiang scratched his head and then said: "Your Highness, are you a little too worried?"
Hearing this, Li Chengqian smiled slightly and said, "Have you forgotten how I defeated Northeastern Sanfang?"
At the beginning, Li Chengqian sent Li Chongyi to cross the uninhabited Daxianbei Mountains where wild beasts roamed, and reached the home of the Xi tribe. Not only did he break the deadlock, but he also ensured the victory of the war.
Cheng Huailiang and Changsun Chong were naturally very clear about this.
"What should we do if the Shu army travels lightly, takes a mountain road we don't know, bypasses the enemy's line of sight, and arrives in Hanzhong?"
Li Chengqian looked at the two of them and said, "We have sky fire and thunder, and they also have it."
"You don't need me to tell you how powerful this thing is."
"It doesn't take much, just one hundred and eighty sky fire thunders, it's enough to burn down our army's logistics supplies."
Li Chengqian narrowed his eyes and said, "When that time comes, this battle will be even more impossible to fight."
The reason why Shu is said to be difficult to conquer is that the biggest difficulty faced is the inability to ensure logistical supplies.
After all, the first article in the Art of War says that troops and horses should move forward before food and grass are used.
In ancient wars, if the front line was fighting and the rear suddenly ran out of food, it would be a very fatal act, and the army might even mutiny.
Although Hanzhong is good, everyone knows its importance.
It is easy for Hanzhong to become a target for many parties.
As a result, setting up a warehouse to store grain, grass and baggage in Hanzhong became the most unwise choice.
And this time it also stumped the other two people.
If there is no longer a warehouse in Hanzhong, where should it be set up? Are they all brought with the army?
This is obviously not possible.
Not only would this slow down the march, it would also waste a lot of manpower.
Fighting in ancient times was far from simple as imagined. If nothing else, let’s take the previous decisive battle in Mobei between Datang and Jieli as an example.
The Tang Dynasty had 100,000 soldiers and horses fighting on the front line, and 30,000 soldiers and horses on both sides.
The dispatch of 130,000 troops seems to be an understatement in the history books.
But Li Chengqian knew that this war was far from simple.
In order to provide supplies for these 130,000 horses, Li Shimin used a full 200,000 civilians to transport grain and grass supplies to them.
Including the subsequent wars that Li Chengqian led his troops to fight, Li Shimin also sent people behind to help him.
Otherwise, how could he lead the army to fight in the front with peace of mind?
But this time, Li Shimin had no intention of helping him tell the truth, and he had to arrange everything by himself.
Li Chengqian watched on the sand table for a long time.
Finally, his eyes were fixed on the location of Wuzhou in Longyou Road...
Li Chengqian squinted his eyes and said, "After thinking about it, we seem to have forgotten something very important..."
After hearing this, both Changsun Chong and Cheng Hualiang looked at Li Chengqian in confusion.
Obviously, neither of them understood what the important thing Li Chengqian was talking about.
At this time, Li Chengqian stretched out a finger and traced it along the mountains near Wuzhou to the location of Jianmen Pass.
"Wuzhou stands on the bank of Langshui River."
He raised the corner of his mouth, looked at the two of them and said, "And the Langshui River and the Weishui River are connected..."
Upon hearing this, Changsun Chong and Cheng Hualiang also reacted suddenly.
"Yeah, why didn't I think of it..."
Cheng Huailiang said bluntly: "We can definitely transport grain through waterways."
"That's right."
"Moreover, transportation to the front line through Langshui is far easier and safer than the original land route."
Changsun Chong also said: "At that time, we only need to send people to take care of the waterways, and we don't need to worry about the rest..."
