In the land of Weinan, mobilization meetings in various factories such as smelters were held one after another, and Sun Xiangfu's voice was dumb and speechless at night, and the workers of various factories were also divided into cars, crossbows, arrows, infantry with standard weapons and the most ordinary workers, peasants and soldiers with their own tools as weapons.

Of course, it doesn't mean that these people are organized into soldiers, and they will immediately be dragged to Chang'an to go to the battlefield, starting tomorrow, they will receive simple platoon training, and the various production factories have not stopped working at night, all kinds of weapons, are still being built, and when everyone begins to serve the war equipment, the output is very amazing.

As for repeating crossbows and chariots, a lot of them were originally produced for reserves, and now, they are also being produced urgently, like the more useful repeaters on the battlefield, there are tens of thousands of spare ones in the warehouse, and now, if we step up production, it is estimated that after three days, there will be at least 80,000 crossbows, and these crossbows are just equipped with the tens of thousands of workers in the crossbow workshop, and they will use them.

The production of all kinds of combat vehicles has not stopped, because they have to be transported to Chang'an, or border cities for defense, there are more than 2,000 spare planes, as well as many produced materials, and hundreds more can be assembled urgently.

Moreover, the civilian board car, there are thousands of stocks here, because this thing is very helpful for agricultural production, as soon as it is listed this year, it has won the praise of the people, and now, it is needed all over the country, and the production capacity of the factory is also very large, when Sun Xiangfu saw these thousands of board cars, he suddenly had a plan in his heart.

These workers, peasants and soldiers cannot be allowed to hedge against the Tibetan cavalry with their swords, so that even if there are a million people, they will be scattered by the 200,000 Tibetan cavalry, and they must rely on a tight array to fight a war with the least losses.

The three-meter-long carts are lined up, loaded with firewood, grass and oil, and pushed in the forefront, which seems to be able to block the impact of the Tibetan cavalry, after all, the war horses are afraid of fire, if a large number of workers, peasants and soldiers are lined up behind these trains, with bows and arrows, and even, with the method of throwing stones, to kill and injure the Tubo people, the effect should be good.

Therefore, the ordinary workers, peasants and soldiers lined up in the back row must carry some fist-sized stones in their arms, and when the time comes, the people in the front row will throw stones, and the people in the back can pass them to the front row, and the rain of stones can hurt people more than the rain of bows and arrows.

Sun Xiangfu told the officials and factory managers in Weinan all kinds of ideas and ideas, and asked them to pass them on one by one, until his own throat was really speechless, and then he fell asleep in the temporary place where he was staying.

Early the next morning, Fang Xuanling, who was in Chang'an, got a report from the messenger of Weinan to report the information, and Fang Xuanling was overjoyed after the report, and he didn't bother why Sun Xiangfu suddenly returned to Guanzhong, with a few guards, he hurried towards Weinan, anyway, Chang'an's military affairs, Du Ruhui was specifically responsible for scheduling.

When Fang Xuanling came to Weinan at noon, the open space of the major factories, their respective team leaders, workshop directors, and even factory directors were training workers to walk, turn, line up, and pass stones, firewood and grass.

These things are simpler than their usual work and work, in fact, since they joined this large group atmosphere, they began to adapt to all kinds of simple behavioral requirements such as queuing and passing, and for the things mentioned by Sun Xiangfu, as long as they are not mentally retarded, they can basically be completed.

Seeing these neatly arranged young and strong migrant workers in Weinan, Fang Xuanling suddenly felt that Sun Xiangfu's idea did not seem crazy at all.

"Fang Xiang is here."

"Your voice, let's talk less!"

When Fang Xuanling heard Sun Xiangfu's voice, he only had a bitter feeling, because he was too hoarse, and if he continued to speak, he was afraid that he would be abolished.

Sun Xiangfu also knew that his voice was going to rest, so he pushed the concept map he drew after getting up this morning to Fang Xuanling, all his ideas about the war, in fact, as long as he looked at the picture, it was clear at a glance.

Fang Xuanling took the drawings on the table, and when he looked at it, his eyes suddenly narrowed.

The whole column of long-handled carts was tightly arrayed, the carts were full of firewood and grass, divided into three directions, forcing the Turkic cavalry to the foot of Chang'an City, the people pushing the carts were all in iron armor, behind them, not far away, all were workers with spears and heavy shields, after these workers lined up closely, those spears and heavy shields were erected, like hedgehogs.

Seeing this front-end formation, Fang Xuanling made up a lot of pictures in his mind, facing the enemy with such a formation, unless the flames on the firewood and grass carts such as the Tubo cavalry burned out, otherwise, they couldn't even rush into the formation, the raging fire itself would burn more than a zhang high, and the long-handled plate car was also more than a zhang long, this was a wall of fire that the war horse could not cross.

Behind the wall of fire, there is a hedgehog formation with spears and heavy shields, and there are two lines of defense like this, no matter what kind of army it is, if you want to cross it, you need to count the dead and wounded.

And behind these two fronts, there are the workers armed with crossbows and longbows, and the least common migrant workers, although they are equipped with short weapons that may not be used, but the main ones used for combat are stones, and the back row will continue to pass stones to them, they only need to throw off their arms and throw them on the battlefield.

After reading all the arrangements, Fang Xuanling felt that the 200,000 Tubo troops seemed to be nothing.

Then, he saw the problems listed below the drawings.

The first is that the board car is not enough, the car array can not be formed, want to surround the Tubo people under Chang'an City from three directions, at least tens of thousands of board cars need to be lined up, after all, a board car, only more than one meter wide, more than 200,000 Tubo cavalry, four or five hundred thousand war horses, the range occupied, at least a few miles long and wide, one direction, almost seven or eight thousand, or even more than 10,000 board cars, and the board cars on the Weinan side, even if all the workshops used for work are counted, there are only about 10,000 vehicles, and the gap is still half.

The second is that the iron armor is not enough, tens of thousands of board cars, a car and two people push, also need 50,000 or 60,000 people, the iron armor of Weinan is only enough for these cart people, and in order to prevent the bows and arrows of the Tubo people from being thrown, the front row of heavy shield pikemen, it is best to be equipped with iron armor, in a strict formation, the gap can be big.

The third is that there is not enough manpower, and if you want to use such a tight formation, you will be surrounded by more than 200,000 Tubo cavalry, in addition to the Chang'an city wall section, the other three sides, each side must have at least seven or eight miles of strict formation to advance, Sun Xiangfu tried to arrange it, one mile, almost more than 10,000 people, that is to say, just one side, it will take seven or eight hundred thousand people, three sides, it will take more than two million people, Weinan, even if you add female workers, it is only about 1.3 million people, the gap, the same difference is nearly half, plus a certain number of people on the city wall, That's a big problem.

The last point is how to let the Tubo cavalry gather under the city of Chang'an, if they scatter to attack the city gate, then, such a crowd tactic, at most can besiege the enemy on one city wall, and such a large number of people are exposed to the battlefield, and the number of subsequent casualties is probably very huge.

Although the idea is good, but it is even more difficult to really want to realize, Fang Xuanling looked at the difficulties raised by Sun Xiangfu and was stunned for a long time, however, from his eyes, Sun Xiangfu saw thinking, that is to say, Fang Xuanling believes that these conditions are actually possible to achieve.

After a long time, Fang Xuanling's eyes showed a hint of determination, "The board car is actually enough, the people of more than a dozen counties around Chang'an, the farmers who bought the board car this year, not to mention tens of thousands, they will all take refuge in Chang'an City in the next two days, and the imperial court can requisition their board cars, and when the war is over, return the new car to them." ”

Hearing Fang Xuanling say this, Sun Xiangfu's eyes suddenly lit up, if the car formation can be formed, then the problem will be solved at least thirty percent, and a car of wood will be burned out, and it will take at least one or two hours, which is enough to determine the outcome of this war.

"Even if the iron armor is not enough, in fact, the difference will not be too much, the arsenal in Chang'an City, plus the forbidden army wearing, at least more than 50,000 pairs of iron armor, as well as tens of thousands of sets of cotton armor that were replaced before, plus tens of thousands of pairs of Weinan warehouses, enough for the soldiers in the first two columns, as for the back row, in fact, the iron armor is of no use at all, because, it is impossible for us to let the Tubo people break through the car formation and the gun shield array, we only need to let them hold the wooden plank high and block the arrows thrown by the Tubo cavalry, we can avoid casualties, and, With those hard hats from your factory, it can also greatly prevent fatal injuries. ”

Fang Xuanling is worthy of being Fang Xuanling, his brain is really good, pull out all the armor of the defenders in the city, and give the people who are arrayed outside the city, and the cotton armor and leather armor that have been eliminated can actually be used now, when the Tang Dynasty did not have iron armor before, hasn't it fought many wars, besides, the city wall of Chang'an City is as high as more than five zhang, and the Tubo soldiers under the city, even if they shoot from the back, the bow and arrow power is not large, and they only need to be equipped with enough wooden shields to defend.

"As for manpower, we are in Guanzhong, the most important thing is manpower, here in Weinan, all the young and strong men and women are counted, there are more than 1.3 million, Chang'an is also a lot, the residents in the city, at least hundreds of thousands can be mobilized, and the people from more than 20 surrounding counties who have come to take refuge can at least mobilize hundreds of thousands, more than two million people, enough."

The permanent population of Chang'an City has already exceeded 1.5 million, and there are at least more than 1 million adults, of which the number of young and strong adults is more than 6.7 million.

Due to the implementation of the large-scale relocation policy this year, the population allocation of each county in Guanzhong is very sufficient, at least more than 20,000 households in a county, 6 or 700,000 households in more than 20 counties, and the number of adults is only a lot more than that of Chang'an, and the number of young and strong people is more than 1 million.

What these people have to do is actually to hand stones to the people in the front row, pass firewood and grass, ensure the flames on the car formation, and ensure that the people in the front row can launch an attack on the Tubo people, and the basic condition is to have courage.

At this point, Sun Xiangfu feels that as long as he agitates, it is not difficult, because the people of Guanzhong have a very strong sense of belonging to this country under Li Shimin's offensive of reversing the hearts of the people, and they don't want their good life to be destroyed by others just beginning.

In the end, it is how to let the Tubo cavalry gather under Chang'an City.

"If the old man, in his capacity as the prime minister of the prison country, pretends to represent the Tang Dynasty, negotiates with Tubo, and invites the Tubo army to hold a grand alliance signing ceremony outside the Yanping Gate, do you say, will the Tubo army gather outside the Yanping Gate because of this?"

"Ah, this"

Even Sun Xiangfu's voice was hoarse, and when he heard Fang Xuanling's proposal, he couldn't help but let out an exclamation, although this is a good strategy, but what you really want to implement it and pay is Fang Xuanling's personal reputation, of course, the history books are written by the victors, and they can also be whitewashed as Fang Xuanling's strategy.
