Speaking from the heart, Li Chengqian actually doesn't have any special views on the eldest grandson Wuji, and in some ways, if it doesn't affect the overall situation, he doesn't mind giving the eldest grandson's family some care.

But if the entire mine was given to the eldest grandson's family, Li Chengqian thought that he couldn't do this.

After all, Datang is not only the eldest grandson's family, and the eldest grandson Wuji is the descendant of the talented man, not his descendant, and if he gives the mine to the eldest grandson, he will not get his allegiance in the end, but will let his descendant have ideas, and the gains outweigh the losses.

Therefore, Li Chengqian did not meet all the requirements of the eldest grandson Wuji, but only ensured that the eldest grandson would not starve to death and not have enough to eat.

……

Putting aside the intrigue between the eldest grandson, the old fox and Li Chengqian, it is said that Liaodong and even the northeast.

After turning Chinese New Year's Eve, before the Shangyuan Festival, a group of miners wearing thick winter clothes came to the mine, and the work of the year began amid the rumbling of cannons.

This is true for coal mines, as well as for copper and iron mines.

However, compared to coal mines, copper ore and iron ore need to be smelted and processed after being mined to refine the ore into metal raw materials, and then the few copper ores are shipped to Chang'an for priority use by the military, and those pig iron are distributed to the small steel mills of various families in Liaodong.

At this time, Da'an City was undergoing a new transformation, and the original city walls were all destroyed, becoming the only city without city walls in Datang.

In line with the principle of waste utilization, the broken bricks and tiles that are removed are basically used to build roads, and some wooden structures are disposed of according to the rarity of the wood.

But obviously, this classification method is not very useful, because no one will use any good wood on the city wall, so most of the wood removed from the city is used to burn cement, and some particularly coarse ones are given to some people who moved here from the Tang Dynasty, and kept them to serve as beams when building houses.

On top of that, more than a dozen bulldozers are working on the periphery of Da'an City, and the entire wasteland has been leveled after the bulldozers have passed, and after the ground has been flattened, the permafrost has also been pushed away, leaving the land that has melted.

In this way, the construction was facilitated, and a large number of workers chased after the bulldozer to tamp the ground, leaving it for the future construction of the factory.

Liu Hongji didn't understand Li Chengqian's efforts to tear down the city wall, after all, in the Tang Dynasty, the city wall was still the best means of defense against the enemy, if there was no city wall, the whole city would immediately become like an unarmed and defenseless woman, and this woman was still walking in the bandits' lair.

But Li Chengqian's reply to him was that he would do it, the city wall must be demolished, and not only Da'an City, but if there is an opportunity in the future, all the walls of the entire Liaodong and even the entire Tang Dynasty will also be demolished.

As for the reason, I'll talk about it later when I have a chance.

After receiving such a reply, Liu Hongji had no good way but to carry out Li Chengqian's order with some complaints and completely destroy the city walls of Da'an City.

……

"Lao Li, you say, isn't this, it's not what the East Palace thinks, how can this city wall be demolished." In Li Ji's Metropolitan Governor's Mansion, after Liu Hongji finished talking about what had happened recently, he poured himself a big sip of wine, and then said with some complaints.

After listening to Liu Hongji's complaints, Li Ji smiled slightly, accompanied him to a glass of wine, and then said with a smile: "This is not an incomprehensible thing, if Hongji cares about the affairs of the military, you will know that this kind of thing is actually beneficial." ”

"What! Does it make sense to tear down the city walls? Liu Hongji rolled his eyes and asked.

"If it makes sense, I'll give you a hint." Seeing that Liu Hongji was still attached to the city wall, Li Ji shook his head with a smile, and then asked, "Do you know Zhenguan Cannon?" ”

"You know, isn't it the one that can shoot more than 500 steps, about the same as a trebuchet?" Liu Hongji stuffed a mouthful of food into his mouth and said with some indifference.

But Li Ji sighed unexpectedly, and then said slowly: "How many years ago was it that Zhenguan Cannon could shoot five hundred steps?" I didn't expect your news to be so far behind. ”

"How far can you hit now? Eight hundred steps? Liu Hongji asked rhetorically.

"It's pretty much the same if you add two more in front." Looking at Liu Hongji's stubborn donkey-like face, Li Ji snorted.

"Poof......" Liu Hongji, who was pouring wine into his mouth, took a sip of old wine and squirted out of his nostrils, including two corianders.

But he didn't care about it anymore, and said with two eyes as big as a cannon: "You say it again, how much?" ”

Li Ji stretched out three fingers: "Standard range, three thousand steps." Of course, if you use the description in the manual, it is called 3,000 meters. ”

"Three, three thousand?" Liu Hongji's eyes were full of disbelief, no matter what, he couldn't understand what the concept of three thousand steps or three thousand meters was, you know, three thousand steps away, even people can't see it.

"And the Zhenguan cannon with a range of 3,000 steps is still the standard equipment of the Sixteen Guards, and some elite legions, such as the Xuanjia Army and the Feifeng Army, I heard that the Zhenguan cannon they are equipped with can already fight 4,000 to 5,000 steps." Li Jisheng was afraid that he would not be able to scare Liu Hongji to death, so he continued to add weight to him: "And I also heard that those guys from the Academy of Sciences are researching the Zhenguan cannon that can hit up to 6,000 steps." ”

To be honest, Liu Hongji, who can fight a three-thousand-meter Zhenguan cannon, can't understand it anymore, as for the six thousand that Li Ji said later, in fact, there is no difference between it and three thousand for him, the left and right are just a number, and he can't understand it or not.

Li Ji looked at the dumb Liu Hongji, and the corners of his mouth twitched slightly: "Hongji, don't think I'm bragging, in fact, now our Liaodong Army has all been replaced with new Zhenguan cannons, and bazookas and the like have all been replaced with new ones, this new type of bazooka is no longer bamboo, but steel, and its range has also reached 1,500 steps." ”

"So you still think the walls are useful? Under the cover of real artillery fire, I am afraid that if you don't even see where the enemy is, the people on the city walls will already be dead. ”

"And with such a large range, what do you think a wall can do? In addition to making your own people flee more slowly, do you think it can withstand that kind of artillery attack? ”

Can you stop it? Of course, he can't stop it, he once saw the Zhenguan cannon back then, that thing is extremely powerful, even if you have a city wall, people will always die, so when the city wall can't play a protective role, it seems inevitable to demolish it. ()
