Chapter 992

After making up his mind, Li forgot to worry and packed up his mood that day and rushed to the Duke of Lu in Chang'an.

It's not that Li forgets worry and has a tendency to be abused. He needs to find stimulation.

He has only one purpose, that is to ask Cheng Yaojin how to be a good general manager of the March.

Although the old rascal's character is not very good, he is excellent in marching and fighting.

Among the famous generals in the early Tang Dynasty, Cheng Yaojin was also ranked as the top one, otherwise Li Er would not have listed him as one of the 24 meritorious heroes of Lingyan Pavilion.

Although Cheng Yaojin was described in the romance of the Sui and Tang Dynasties as a reckless general who only knows three axes, in fact, Cheng Yaojin, an old man, is a very smart man. If anyone treats him as a reckless man, he is a fool.

Li Qieyou was just a puppet army fan in later generations. He didn't know how to arrange troops and battle.

Li Er rushed the ducks to the shelf and insisted on putting him in the position of the chief manager of the march of the western expedition. He had to cram his feet and run to the old hooligan for scriptures.

After all, as the general manager of the March, it would be hard to say if all military affairs were left to Niu JINDA and Xue Wanjun.

Cheng Yaojin was delighted when he heard that Li forgets worry actually took the initiative to "beg for abuse".

"Wow, hahaha, it's rare that Ziyou should take the initiative to come to the door! Since you're here today, don't want to go. Come and prepare the banquet!"

Seeing that the old rascal wanted to "get angry", Li forgot to worry and quickly raised his hand to surrender: "Uncle Cheng, my nephew came to visit uncle Cheng today to ask Uncle Cheng about the army. This wine will be exempted. When my nephew returns from the western regions, he will be drunk with uncle Cheng, OK?"

Cheng Yaojin glared at him discontentedly: "zhiniang thief, what does this drinking have to do with you? Don't grind haw, just like women!"

After that, the old rascal didn't wait for Li forgetful worry to oppose. He directly reached out to catch Li forgetful worry and strode to the main room.

Li Qieyou immediately regretted it.

Nima, I want to ask about the army. Does he go to find Li Jing Buxiang? Isn't it nice to find Qin Qiong?

Why do you want to "be cheap" to find Cheng Yaojin, an old rascal?

Before Li forgets his sorrow and regrets, Cheng Yaojin has pressed him into the main room of the Duke of Lu. The handmaid of Cheng's house presented the wine and vegetables with the potential of hiding her ears and stealing the bell

Li forgets to look at the wine and dishes that are piled up in a moment. He wants to ask Cheng Yaojin how the cooks and maidservants in his residence are trained?

If Datang has a Guinness world record, it will be the first to serve wine and vegetables!

Looking at the height of the sorghum wine in front of him, Li forgets to worry and sighs helplessly.

"Uncle Cheng, I brought a new wine to Uncle Cheng today. Please taste it."

In fact, Li forgot to worry about the reaction of the old rogue. Therefore, in order not to be filled with mud, he took two barrels of beer to the door.

"Oh? But what kind of beer? Chumo told me a few days ago that the beer tastes very light, but it's better than cold and sweet. Now that you have the intention to bring it, try it."

Cheng Yaojin is a good wine. I heard that Li forgetful brought new wine. Naturally, I don't mind tasting it.

Li forgets worry and quickly orders someone to send the beer barrel to the lobby. He personally fills Cheng Yaojin with a full glass of beer.

Cheng Yaojin took the wine cup and drank it directly. He poured a glass of iced beer into his mouth. He was very satisfied and hiccupped.

"What kind of beer is used to quench thirst? It's good." Cheng Yaojin smacked his mouth and motioned Li forgetful to fill it up again.

Taking advantage of the effort of pouring wine for Cheng Yaojin, Li forgot to worry and quickly told him his intention.

"Uncle Cheng, you have to help me. Whether I can get back to Chang'an before my wife gives birth depends on Uncle Cheng's advice."

Cheng Yaojin looked up and laughed: "Ziyou, I always thought you knew astronomy and geography, but I didn't expect you to be timid. Is it an outing when you start as an army? You expect to lead 150000 troops from Jingzhou to the western region in three months? Isn't that a dream?"

Li forgot to worry and was stunned. He didn't understand what Cheng Yaojin meant?

Jingzhou to gaochangguo, more than 4000 miles, is absolutely right.

Although Li has never been in contact with the army, he is also generally aware that the daily marching distance of the ancient Chinese army is about 30 to 40 kilometers.

After conversion, you can walk more than 4000 miles, which is just two months. He estimated that in three months, he already felt that time was very rich. Why did Cheng Yaojin say he was dreaming?

"Please give me some advice."

"Ziyou, do you know the concept of 150000 troops? Let me tell you this. If the 150000 troops set out in line, the forward has arrived at the destination and started to camp, and the rear troops have not yet left the camp, okay?"

"Moreover, the speed of the army is based on the speed of the baggage team. Four hours a day, at the speed of the baggage team, it is only 40 or 50 miles a day at most."

"Moreover, if there is wind and rain and the army can't travel, it can only stay in the camp. It's quite normal that the army needs to rest after marching for many days. Therefore, it's impossible for 150000 troops to rush to Gaochang country in less than half a year!"

Cheng Yaojin's words immediately stunned Li forgetful.

As a military fan, he also knows that Cheng Yaojin didn't deceive him.

At that time, the 800000 troops of the former Qin Dynasty were known to be cut off. As a result, the former army was defeated, and the latter army was still on the road.

This is the barrel principle. The marching speed of the army needs to be consistent with the slowest unit in the army.

But in Li's mind, the logistics of the army should not be so slow.

Li forgot to worry and asked, "Uncle Cheng, but since I got out of the four-wheel carriage, the transportation speed of logistics is not slow. It's no problem to March hundreds of miles a day, not to mention 200 miles a day."

Cheng Yaojin looked up and poured down a large glass of beer, glanced at him obliquely: "bullshit, can you get into the desert with those four-wheel carriages?"

Li forgot to worry about hearing the speech. If he was struck by lightning, he stood on the spot

He really forgot that when the army marched through Dunhuang County, it would enter the vast desert.

Tengger Desert, the fourth largest desert in China, is more than 160 kilometers wide. Those four wheeled carriages can't enter anyway.

Today, the Tang Dynasty has established a trade center in Dunhuang County, and a large number of goods are transported to Dunhuang County by four-wheel carriages, which greatly shortens the transportation distance between the Silk Road caravans.

However, from Dunhuang county to the western regions, the caravan must change into a camel caravan before it can move on.

The same is true of the army. To supply the supplies of 150000 troops, we must use a large number of camel teams in order to meet the needs of the army.

In this way, the marching speed of the Tang army must not be faster.

Moreover, to pass through the desert, in addition to food, grass and baggage, the Tang army must also carry enough water sources. Under the guidance of the guide, it can pass through the desert

After Li forgets worry and wants to understand this, he can't help sitting down dejectedly.

Paralysis, if so, how could he rush back to Chang'an City in half a year?
