Zhu Cijiong really didn't think that the north would have to defend, let alone consider the north defense and the west defense together, because the north is the Arctic Ice Ocean, will there be an enemy invasion?

Sun Yuanhua's opinion was different, he pointed to the map and continued: "The north of Siberia is the Arctic Ice Ocean, although at least half of the year is in the ice period, but there is still half a year to navigate, and the anti-Habsburg coalition powers all started on the sea, and the naval strength should not be underestimated, if our rear air defense is weak, they are very likely to use warships to land from the north, after all, the Siberian Plain has two major water systems, water transportation is developed, and in the absence of railways, it is also very convenient to rely on naval invasion." “

When Zhu Cijiong heard this, he only felt that his back was cold, it was his carelessness, didn't the great powers start by relying on their navy, and the more they got behind, the stronger their navy became, now they have mastered steam power, the devil knows what their navy has developed, if they use the navy to bypass the Osan line from the Arctic ice sea, then the whole of Siberia will be in danger.

Thinking of this, he hurriedly asked, "Chu Yang, then how do you say this piece should be defended?" “

Sun Yuanhua nodded, pointed to the map and continued: "Due to the underdeveloped water and land transportation on the Wushan line, it is actually not suitable for stationing too many troops. “

Two legions, it seems a little too little, you must know that now Tsarist Russia alone has 200,000 troops, and the other five powers, except for the Netherlands, can easily pull out 100,000 troops, so it is 600,000 troops, 200,000 against 600,000, or thousands of miles of defense line, how can it be prevented?

Zhu Cijiong asked puzzledly: "There are only two legions, I'm afraid I can't hold it, right?" “

When Sun Yuanhua heard this, he said embarrassedly: "Your Majesty, the Wushan line stretches for thousands of miles, that is, there is no big river running throughout, and there is no railway line, the transportation of grain and grass can only rely on manpower, if too many troops are sent, the grain and grass can not be transported at all, unless it is like now, hoarding millions of troops in Wushan City, where transportation is relatively convenient, to deter the heroes." If they are scattered, they can only hoard 100,000 horses in Wushan City, and then build fortresses in various mountain passes in the north and send 100,000 horses as a warning. “

Hoarding a million troops in Osan City is only temporary, if it is hoarded there for a long time, the loss will be amazing, this will definitely not work, if it is just to send 200,000 horses to garrison the first line of Wushan, it is not equivalent to giving up the natural barrier of Wushan, he asked even more puzzled: "Do you mean to give up the first line of Wushan?" “

Sun Yuanhua nodded and said: "Yes, Your Majesty, through our later reconnaissance, we found that Tsarist Russia actually did this, they built dense fortresses on both sides of Wushan, but the first line of Wushan only built fortresses in a few mountain passes, not even a city, so Weichen has this idea, that is, to use Wushan as a cordon and build more fortresses on the Siberian Plain, so that no matter whether the enemy attacks from the north or from the west, we can be invincible, and there is no pressure to transport grain and grass." “

There are already more than 100 fortresses on the Siberian Plain, and they are still being built, so how many men and horses will have to be sent to garrison them!

Zhu Cijiong felt that he couldn't keep up with Sun Yuanhua's train of thought, so he simply didn't ask, just looked at Sun Yuanhua, and then looked at the map, waiting for him to explain in detail.

Seeing the emperor's expression, Sun Yuanhua hurriedly pointed to the map and continued: "Now there are more than 100 fortresses in Siberia, and we plan to move to the past There are more than 40 capitals and more than 200 guards, so Weichen thought, build more than 100 fortresses, choke the main roads of water and land everywhere, and let all the guards live in the fortress, as long as it is equipped with a sufficient number of artillery, even if the guards are stationed, it is difficult for the enemy to conquer, and we have enough time to mobilize a large army to support." This not only saves troops, but also strengthens defense, and allows the guards to get more exercise, what does the emperor think? “

Garrisoned with a million guards, what a great idea!

However, it is impossible for all the guards to be equipped with muskets, so they are far inferior to the regular legions, how long can they withstand it, and what if they can't withstand it?

Zhu Cijiong said with a little hesitation: "Siberia is far away, can the tunwei hold on until the reinforcements arrive?" “

Sun Yuanhua said confidently: "If the emperor is not at ease, he can station a legion in Tunguska City and Rem City, and be ready to support various fortresses at any time, in this way, he will definitely be able to hold back the enemy and defend until reinforcements arrive." “

When Zhu Cijiong heard this, he couldn't help but nod and said, "Well, Chuyang's suggestion is very good, do you have anything to add?" If not, the defense of Siberia will come as Chu Yang said. “

There are three people left, Yang Sichang, a secretary of the Ministry of Commerce, Zhang Cai, a secretary of the Ministry of Commerce, who is in charge of the economy, and Zhang Pu, a secretary of the Ministry of Transportation, who is in charge of transportation.

Zhu Cijiong looked over one by one, and the first one was Yang Sichang, the secretary of the ministry.

Yang Sichang saw the emperor coming over, and hurriedly arched his hand and said: "Your Majesty, Weichen thinks that all the fortresses should be connected to the telegram, so that the enemy army will be even more difficult to move an inch. “

Zhu Cijiong nodded and agreed: "Well, what Wen Qiao said is good, this must be there." “

Immediately followed by Zhang Cai, the secretary of the Ministry of Commerce, he didn't have any suggestions, but worried: "Your Majesty, Lord Sun, what if the enemy also makes armored combat vehicles, can the fortresses still be defended?" “

Naturally, don't worry about this problem, armored combat vehicles are all invented by themselves, how can there be no way to deal with them, the method Zhu Cijiong has already taught Sun Yuanhua them, he just gestured to Sun Yuanhua with his eyes, Sun Yuanhua immediately explained: "Don't worry about this Lord Zhang, we have ways to deal with armored combat vehicles, such as digging traps, incendiary bombs or something, even if they imitate armored combat vehicles, it is useless." “

When Zhang Cai heard this, he nodded again and again, admiring, he was finished.

Immediately followed by Zhang Pu, as soon as he saw the emperor coming over, he actually stood up and bowed to Zhu Cijiong, and then said to Sun Yuanhua: "Lord Sun, can you borrow an ash rod to use." “

When Sun Yuanhua heard this, he hurriedly handed him the ash rod.

Zhang Pu took the ash pole, pointed to the map and said: "Your Majesty, Weichen thinks that in order to speed up the reinforcements, it is necessary to establish a water and land transportation network in the Siberian Plain. “

When Zhu Cijiong heard this, he nodded with interest and said, "Well, yes, hurry up and talk about it." “

When Zhang Pu heard this, he pointed to the map and introduced: "For example, water transportation, now the Yeni River, the Ob River and even the Wu River are separate waterway systems, if the enemy attacks from the west of the Ob River Valley, the legions stationed in Tunguska City must first take a train to Rem City, and then turn to the waterway; If the enemy attacks from the north of the Yeni River valley, then the legions stationed in Rem City must first take a train to Tunguska City, and then turn to the waterway, the army must go out to fight with grain and grass, weapons and ammunition must bring a lot, so it is very delayed to go around, Wei Chen suggested that a canal be dug here to connect the Yeni River valley and the Ob River basin, and then dig a canal here to connect the Ob River basin and the Wuhe River basin, so that the waterway transportation will be much more convenient, whether it is wartime support, or peacetime transportation is much faster. “
