Fighting a war is about comprehensive strength, not something you can do if you have the courage. Weapons and equipment, large ordnance, food and grass materials, medical support, and so on cannot be left unconsidered.

And when it comes to these, we have to mention Li Chengqian, the crown prince.

In the past few days, he has been getting closer and closer to the border, and Li Er has become more and more fond of talking about the eldest son who was left at home by himself.

After setting up camp on this day, the old man saw the soldiers of Zuofu (the predecessor of Zuo Qianniuwei) patrolling outside, and somehow laughed happily, and the eldest grandson Wuji on the side was confused.

"Mowgli, how good you said it would be if my sons were like Cheng Qian, why should I come out to fight on the battlefield at such an age!" After laughing, Li Er sighed and said obediently.

"Huh?" The eldest grandson Wuji was stunned for a moment, and he didn't react for a long time, and the only thought in his mind was: If your sons are like Li Chengqian, it is estimated that you will not live to this day at all, I am afraid that you will be angry to death a few years ago.

Li Er didn't wait for the eldest grandson Wuji to answer, and after sighing, he pointed to the soldiers who were patrolling and guarding: "Look at it, if my Datang had such military power back then, why couldn't I even take down that Xue Ju, and why let Dou Jiande and Wang Shichong occupy half of the country." ”

As His Majesty the Emperor's guard, not to mention the combat effectiveness, the military posture and military appearance of the left and right governments are definitely the first in the whole army, and with a handsome 07-style military uniform, the mighty and majestic air comes out of the body.

"Yes, I don't know where I learned this method of training soldiers, it is really extraordinary, and the soldiers trained by this method are indeed more than twice as strong as before." The eldest grandson Wuji, even if he was stupid at this time, knew that Lao Li was thinking about his son, so he followed his words.

Anyway, Li Chengqian is also his nephew, and it is not a big deal to praise one or two sentences, and he does not have such and such scruples like others.

"Not only is it twice as strong, if it is a single soldier, it may be twice as strong, but if it is an army of fire, I am afraid that it will be twice as strong, and the army of a party can even reach more than three times." Li Er shook his head and denied the statement of the eldest grandson Wuji.

After all, Li Er is also an old oilman on the killing field, and he knows that the most powerful part of the army is not how capable a certain person is, but in the method of combined attack and cooperation.

Recalling that at the beginning, Li Chengqian asked these guys to stand in line, carry logs, and practice falling ...... on the high platform, many people didn't understand at that time, and the old generals of the Sixteenth Guard also had a lot of complaints.

But when they saw the results of the training, everyone fell silent, and the battle of 3,000 to 10,000 on the school field made these old guys realize that they could no longer stick to the old point of view, and that they had to master this new way of training.

Therefore, after that military drill on the military field of the school, the sixteen guards all changed the training method of the past, changed to training closer to actual combat, and also began to pay attention to the coordination between the soldiers.

This is also the reason why any one guard will walk in two people and three people on the road now.

Of course, some people may think that this is not realistic, and that this situation can only occur in later modern times. But don't forget, Datang is not modern, there is nothing in Datang that corporal punishment cannot be said, seventeen laws and fifty-four beheadings will really kill people, so although the training of queues and military formations is not long, the effect is far higher than that of later generations.

"Erlang, what you are looking at is the military appearance, do you know what you are looking at?" There were no outsiders around, and in private, the eldest grandson Wuji didn't call Li Er His Majesty, but just called him by his name like a friend.

"Oh? What does my uncle value? Li Er was in a good mood, and when he saw that the eldest grandson Wuji was selling Guanzi, he took advantage of the situation and praised it.

"Logistics!" The eldest grandson Wuji took a long breath and smacked his lips and said, "The four-wheeled carriage is far more loaded with grain than before, and the speed is not slow; The newly built cement official road has shortened the place that used to take a month to reach the current ten days; The construction of Yicang has given my Datang a lot more grain storage ......."

Since Li Er thinks about his son and thinks of his son's goodness, the eldest grandson Wuji will do what he likes and say, Lao Li wants to praise his son, he can't sing a one-man show alone, he must have someone to sing with him on the side.

However, as he spoke, Lao Li and Eldest Sun Wuji's faces changed a little, and they glanced at each other in silence, and they both saw a trace of doubt in each other's eyes.

From the second year of Zhenguan to the current eighth year of Zhenguan, let's see what kind of changes have taken place in the Tang Dynasty in six years, and some problems that are not usually noticed have all been exposed in this Eastern Crusade.

First of all, the roads, which were previously dirt roads are now basically paved with cement, which makes it possible to march and transport supplies several times faster than before.

The canal, which has been continuously dredged in recent years, also played a great role in the process of this crusade, and grain from the south could be transported to the base camp in the rear through the canal and at a fast speed.

The second is grain, with the big granary of Linyi, coupled with the Yicang all over the territory of the Tang Dynasty, so that this Eastern Crusade does not have to worry about raising grain and grass at all, as long as the grain and grass in the Yicang in various places are pulled out and loaded into trucks or ships.

The above two items don't seem to be important, but if there is a real war, it is really a grain harvest behind him, and even if it is a stalemate, Li Er dares to block the country of Goguryeo for a few years.

Then there is the equipment, all kinds of new equipment are now emerging in an endless stream, and the craftsmen are desperately researching weapons and ordnance that are more powerful, simpler in structure, and more convenient to use. In the past two years, even the newly researched equipment has become obsolete before it has time to equip the troops.

Take the bed crossbow as an example, after the current bed crossbow was taken out, Li Er didn't even know what the thing was called, but after it was assembled, Comrade Li even felt that he could play with this thing even with only one hand.

As for weapons such as knives and arrows, not to mention, Bailian Steel is not a rarity now, with a hydraulic press, it doesn't take much time to hit a Bailian Steel Knife, and it doesn't have to waste too much manpower.

When did this begin? When did Datang's craftsmen become so smart? And the enthusiasm for the study of new equipment will be so high? Could it be that you have taken some kind of smart drug?

Li Chengqian, all this is because of that kid, the bed crossbow is the first one he to change, and the method of steelmaking is also the first one he puts forward suggestions for improvement, as for the hydraulic press, needless to say, no one will think of that thing except for that kid.
