Now Pingluan City has not been defeated, and it is Guo Kan who is defending the city. The Mongol naval forces under his command were now turned into land forces. In addition, Guo Kan also served as the head of Pingluan Road, and was left in Pingluan as cannon fodder - the reason for this arrangement was because Guo Kan was not trusted by the Mongols, and his father-in-law Shi Tianze took refuge in the Eastern Tang Dynasty. If it weren't for the fact that he still had more than 3,000 Han troops who followed him all the way back from the Western Regions, Kublai Khan might have made people ask him for blame.

However, not asking him for guilt does not mean that he can be admitted to Yanjing...... Who knows if this guy will come together inside and out? Brother Mo and Wuliang Hetai didn't dare to take this risk. In fact, Yan Zhongji was arranged in Yuguan for the same reason, his wife was the daughter of the Qufu Kong family, and the Qufu Kong family had already voted for the Tang Dynasty, so he was naturally not trusted by the Mongols. In addition, Yan Zhongji's father, Yan Shi, is a well-known wall grass, first Shijin, then to the Song Dynasty, and then to Mongolia, a proper three-surname slave. Brother Mo and Wuliang Hetai will believe in the Yan family, that is blind.

For Yan Zhongji, who is famous for his Yuan song, Chen Dexing actually doesn't take it seriously, just look at Yan Zhonghe's treatment. But for Guo Kan, the prototype of Guo Jing and Guo Daxia, Chen Dexing attaches great importance to it.

It's not that he is afraid of being slapped to death with ten slaps of the dragon, but because of Guo Kan's experience of following Hülegü in the Great Eclipse of the Western Regions, who is said to have been through a hundred battles and has dealings with the Great Cannibals, Mamluks, and Crusaders.

Such a character is still very useful for navigating the Western Regions in the future. Moreover, Guo Kan's soldiers can indeed fight, and Chen Dexing has learned it on Jianghua Island. Although it has gone through nearly two years of development, the combat effectiveness of the sergeant soldiers is not comparable to the past, but it is not easy to take Guo Kan without any effort.

So. Zhang Shijie will mention that he will leave Guo Kan not to fight for the time being, and go to get Yanjing first.

"How many people are there in Yanjing City? How much grain and grass do we have? Chen Dexing asked thoughtfully.

"There were more than 100,000 people in Yanjing," said Zhang Xizai, the deputy military division. "Now that our soldiers are pressing, the population of Yanjing may increase. Tens of thousands of people in Kaiping City may also enter Yanjing. As for our grain and grass, the army carried 508,000 stones, including horse feed, and a total of more than 330,000 men and horses. At present, two and a half percent have been consumed, and the remaining military rations and horse materials can still last for 20 days. ”

Zhang Xizai's answer was very careful, and the reason why he was able to sit firmly in the position of deputy military division was because of this carefulness. The size of the army, the terrain, climate, and road conditions of the battlefield. He knows almost everything, like an encyclopedia. Compared with. The military advisor Zhang Shijie is a little careless, just cares about the general situation, and does not ask about the details.

"So how much grain and grass is there in Yanjing City?" Chen Dexing asked again.

This time, Zhang Xizai did not answer, because he did not get a report in this regard. But Zhang Shijie has already heard the clues.

"Your Majesty, are you worried...... The battle of Yanyun is protracted? Zhang Shijie frowned and thought for a moment, "Are you worried that Kublai Khan's main force will come to Yanyun?" ”

"Zhang Xizai, what do you think?" Chen Dexing asked Zhang Xizai.

"Possibly...... The latest news, Kublai Khan still has not left the customs to meet Li Tang. Zhang Xizai thought for a moment. He added, "The probability that he will come to Yanyun is not less than 50%. ”

News from Li Tang's side also came from time to time, and now it is certain that Kublai Khan did not go out of the customs to fight Li Pu. This is very abnormal, and now Chen Dexing and the four kings of the Mongolian host are fighting. For the time being, I can't spare my hand to help Li Pu. This was the best time for Kublai Khan to defeat Li Pu. But Kublai Khan seems to be letting go of such an opportunity!

Chen Dexing smiled: "He's coming to Yanyun, it's just two tables of people coming to a banquet!" ”

"The four kings of the Mongol host country have at least 100,000 elite soldiers, and Kublai Khan will bring at least 100,000 people. Yan Yun originally had no less than 60,000 soldiers...... Three confluences are 260,000! Zhang Shijie smacked his lips and his brows furrowed.

Chen Dexing shook his head. Said: "We must also add more than 600,000 subordinates of the four kings of the host, and at least 200,000 officials and people in Yanjing City." Kublai Khan entered Yanjing. There are more than a million mouths to raise. And if we want to enter Yanjing, there are also three or four hundred thousand people to feed! This Yanjing is good, but it's a pity that it's too much food! ”

Because the population base of the Northern Ming Dynasty is still too small, the granges allocated to Shijue and Baqi can only be widely planted, and the final harvest is naturally thin. Therefore, food has always been a big problem, but fortunately, there is such a large rear as Goryeo that can provide supplies, and it can also buy grain from the Southern Song Dynasty and Japan through Guò sea trade.

But the problem is that once the battle of Yanyun cannot be resolved quickly, after a year and a half, the problem of feeding hundreds of thousands of soldiers and civilians on the front line will still be a big problem. Moreover, as long as the war drags on until next spring, the spring ploughing area in eastern Liaoning will be reduced by at least 50 percent, and the grain supply in next autumn will be greatly tightened.

At that time, if the war continues, Chen Dexing may have to evacuate Yanyun with tears like Zhuge Kongming, who always retreats after running out of food.

Therefore, the supply of grain and grass has always been the top priority of the General Staff Department of the Northern Ming Army. This time, the autumn army was chosen not to affect the autumn harvest, and for the Han, Semu or Mongols who were "plundered" in the war zone, the General Staff Department and the Political Affairs Department of the Northern Ming Dynasty also formulated a complete plan for the resettlement of Tuntian. In order to devote this labor force to food production to the fullest.

This is not the time of the peasant uprising in the late Ming Dynasty and the Taiping Rebellion, and China's population is large enough that it can use the tactics of rogue to loot and raise military rations to coerce soldiers. The current situation in the northern land is similar to that of the Three Kingdoms at the end of the Han Dynasty, where the population is too small and there are too many robbers......

Watching the large groups of Han people helping the old and the young, carrying packages and wooden sticks, they were driven out of the fortress. Chen Dexing still sat down on a big horse knife on a bed under the banner of the Chinese army. Holding the thick beard under his chin, he squinted his eyes and thought to himself.

Fighting a war has never been as simple as two armies making an appointment to fight in a place.

Spend soldiers' rations and fight logistics. It has always been a common method used by soldiers, and Kublai Khan, who was older than the military array, would definitely not be unexpected.

Kublai Khan couldn't fight the battle of being bombarded in Yanjing City, that was the style of the Southern Song Dynasty. If he were Kublai Khan, he wouldn't be so stupid. Knowing that the Northern Ming army had cannons that destroyed the city walls, they went to defend the city. Moreover, the advantage of the Mongols is not to defend the city but to fight in the field, and 200,000 horsemen gathered on the Great Plains, even the soldiers of the Northern Ming Dynasty and the Eight Banners of the Northern Ming Dynasty cannot break it with one drum.

If the Northern Ming army marched into Yanjing City again and carried the food problem of the people in the city on their backs, then the Mongols could win by attacking their own logistics line!

Therefore, this Yanjing City is likely to be a pit that is easy to enter and difficult to get out!

……

"The King?"

A soft question dragged Chen Dexing out of his full stomach. Turning her head again, the little demon girl Li Cuixian, who was already a woman, was smiling at Chen Dexing.

"Xian'er, is there anything good?"

Li Cuixian smiled lightly and handed over a letter. Chen Dexing looked down, and the letterhead on the letter was "Tang Emperor Li", Li Pu's letter.

"Old Tarzan ......"

"Daddy, he has seen through Kublai Khan's plot and is waving his army north to Taiyuan." Li Cuixian said with a smile, "In addition, my father also let the third brother of the concubine oversee the army out of Jinan. ”

Chen Dexing thought for a while and asked, "Go north to Taiyuan?" Taiyuan is now ......"

"It's still in the hands of the Tang Army."

Li Yinuge, the former governor of Taiyuan, Mongolia, and Daluhua Chidai Quxue raised troops corresponding to Li Pu, and were named the envoy of the Hedong Festival and the Hezhong Festival. The Tang army that Li Cuixian mentioned refers to the army of Li Yinuge and Dai Quxue.

"In this way, the Tang army should be able to take most of the east of the river," Chen Dexing pondered, "The mountains and rivers in the east of the river have the tendency to be built from a high position." Jinan is also a strong city, and backed by Yidu, which is enough to be protracted. Our soldiers also controlled the eastern foothills of Yanshan according to Tanggu and Pingluan, which can also last......"

Li Cuixian said with a smile: "Today's Yanyun battle situation is like a big game of chess, the corners have been occupied by the Tang and Ming families, only the middle is still blank, just waiting for the Mongols to drill into it!" King, after this battle, the world is divided into two parts...... This capital of the Ming Dynasty, it is better to move to Yanjing. ”

Chen Dexing was noncommittal, just stood up and raised his hand, and Zhang Shijie and Zhang Xizai, who were flashing aside because of Li Cuixian's arrival, came up again.

Chen Dexing said: "Let's go, go to Pingluan City, and go see if Guo Kan's granite head has figured it out." ”

……

Dangdangdang......

In Pingluan City, there was a crisp sound of tapping in Guo Kan's office. Guo Kan was holding a hammer and beating a pair of plate armor hard. This plate armor was personally sent in by Guo Shoujing, the envoy of the Northern Ming Army, this morning.

"Zhonghe, don't waste your efforts, how can a steel plate 6 centimeters (about 2 millimeters) thick be smashed? This thing is forged with a hydraulic hammer after it is red, and it is absolutely invulnerable, and it is the same with any sword or sword you use, even if you take out your precious Uzi steel knives and chop them, it is useless! ”

Guo Shoujing is an honest man - the nature of a scientist is to seek truth from facts. Guo Kan is a relative of him, of course he knows his temperament. Hearing him say this, it was not in vain, he threw the hammer to the ground and snorted.

"A certain family doesn't believe that Chen Dexing can equip his tens of thousands of troops with this kind of steel armor!"

"I didn't say anything about the steel armor of the Ming soldiers," Guo Shoujing smiled, "This steel armor is expensive, and you can't take it down without a thousand pairs." Now there are less than 3,000 pairs of such good armor in the Ming Wang's army, except for the Ming Wang's Guards Division, which has a brigade of steel armor soldiers, that is, some higher-grade officers have such good armor. ”

3,000 pairs is not a lot!

Guo Shoujing gasped, how could he not know the goods? That brigade of steel-armored soldiers is going to the battlefield, but it will be sharp. A crossbow would be difficult to injure them, and in melee combat, Uzisteel's sword should be able to pierce through the armor. However, the edge of an ordinary sword is too soft, and it is not possible to slash, and it takes great force to stab. If these steel-armored soldiers are paired with rattan cards and steel knives of the same material, whoever is their opponent will be sent to death...... (To be continued......)
