Lu Su said: "Lord, the land occupied by our army, from west to east, stretching for thousands of miles, from south to north, only more than 200 miles, so distributed, easy to be cut off by Cao Cao, Liu Biao's generation, for today's plan, the lord must quickly attack Jingzhou, there are Jianghan and Han rivers outside Jingzhou, there are mountains and tombs inside, the city is solid, the land is fertile, the people are rich, if you occupy here, you will have the foundation to fight against Cao Cao!" ”

Wei Yan understood what Lu Su meant, the place he occupied now was a serious flaw, and there was no strategic depth!

A larger buffer zone allows the force to wake up from the panic after losing the first encounter and begin to plan a more far-sighted strategy than just a defensive or counterattack. Pen, fun, pavilion www. biquge。 info

In the initial situation of being invaded by the enemy and losing the defense, if the enemy forces let the mobile troops break through the front line in a blitzkrieg and quickly penetrate the strategic points, the forces that do not have a certain depth will soon have the upper hand in the strategic maneuver, and this will make the counterattack operation more difficult or even abortive.

Moreover, because there was no strategic depth, the enemy army was beaten to the capital Yiyang New Town at every turn, and grain production, trade and transportation were all interrupted, which was very harmful to the development of strength.

And if Jingzhou is taken thousands of miles deep from north to south, the strategic depth will be greater, and it will be more convenient to develop the economy and military!

"What Zijing said is extremely true!" Wei Yan said: "When the combined forces of Cao Cao and Liu Biao are defeated, they will quickly attack Jingzhou!" ”

On the second day, Wei Yan, Xu Shu, Lu Su, Xu Huang, and Guan Hai led 40,000 horses and horses, crossed Huaishui, and marched to Yiyang New Town.

Wei Yan's concubines Da Qiao, Xiao Qiao, Foot Trainer, and Yuan Xin all followed the army and were protected by female soldiers.

Yuan Xin returned from completing the mission in Xiapi City and was rewarded by Wei Yan's favor.

Wei Yan also asked Diao Chan and Lu Lingqi about their appearances, and Yuan Xin described them truthfully.

Wei Yan was a little moved, Lu Bu's wife, daughter, and subordinates must not be cheap Cao Cao!

Without Liu Ye by his side, Wei Yan said to Lu Su: "When the Son of Heaven was in Chang'an, he handed over Wang Yun to Li Dao Guo Yan in order to steal peace, and to serve such a ruthless monarch, do you want to become Han Xin's second?" Zijing, I agree with your strategy, but now it is naturally loyal to the Han family. ”

Lu Su was overjoyed, he was originally worried that Wei Yan was really willing to serve the Liu Han royal family, but it turned out that the lord had already made up his mind in his heart.

Kongkong prompted: "Lord, Lu Su's loyalty has soared by 50 points, and it is now 180 points!" ”

After traveling for more than ten days, he did not encounter Cao Jun, and the calm was terrible.

On this day, I passed through Qisi County.

Period Si lives in the northern foot of Dabie Mountain, the yin of Huai Shui, the rivers and lakes in the region are dense, there are Huai River, Bailu River, Qi Si River three rivers compete for the stream, there are more grass lake, Fangjia Lake, rabbit lake three lakes reflect each other, because it is convenient for irrigation, so Wei Yan occupied this county, then ordered Shi Tao, the captain of the agricultural school, to gather the displaced people, there to Tuntian.

The places Wei Yan passed along the way, every dozen miles, you could see the towering castles built by the Tuntian Corps, the hard-working Tun people on the fields, the herds of chickens, ducks, cattle and sheep running around, and the curling smoke rising, and everywhere was filled with a strong atmosphere of fireworks in the world.

At this time, Shi Tao, the captain of the Diannong School, was thinking about it, and when he heard that Wei Yan's army was passing by, he hurriedly brought the Diannong Lieutenant, Diannong Sima and others here to greet him.

Lu Su looked up at the castle that was the Tuntian Corps in the future, it was very different from the previous city, it was no longer boxy, but concave polygon, and the appearance was very strange and not beautiful at all.

Shi Tao saw Lu Su staring at Wubao, and said with a smile: "The lord is really a talent, and he knows how to build a city. Since the lord handed over the sketch of the building called the fortress to Zaixia, Zaixia took advantage of the leisure time to gather all the people of the tun and concentrate on building this fort. This kind of fortress is very easy to build, and it is also convenient to expand, as long as you keep building the same shape of the city wall along the prismatic city wall, and form a sandwich between the walls, you can expand it, and the defensive ability will not only not weaken, but will be enhanced! ”

Lu Su pointed to those angular city walls and asked, "Captain Shi, why did you build so many angular city walls?" ”

Shi Tao replied with a smile: "This is the beauty of the fortress, protruding many angular city walls, in order to allow the defenders to carry out multiple blows to the attacker, no matter which city wall the attacker attacks from, the back will be exposed to the defenders on the side wall on the other side, and each side is within the range of the bow and arrow, so that the attacker has almost no chance to climb the city wall, either killed by the defenders in front or shot to death by the defenders behind!" Three months ago, Sun Xiang, the puppet of Runan, the general of the Yuan Shu Department, knew that there was a lot of grain in this fort, and led 5,000 men and horses, and wanted to capture this dock fort, but there were only 1,000 tuntian soldiers on the fort, but they were shot and killed all over the field, and fled in embarrassment. ”

Wei Yan laughed and said: "Guangyuan, I also heard from the Hu people who came to Wuyuan County in the Western Regions that the Great Qin State in the west of the Western Regions has this style of castle, and the defense is very safe, so I wrote it down, this fortress is really not my creation." By the way, Guangyuan, I've been busy with other things recently, and I haven't asked about the Tuntian Corps, so you can give me a brief report now. ”

Shi Tao did not go back to check the records, and with his memory, he told the current development of the Tuntian Corps: "Now there are 220,000 people in the Tuntian Corps, including 180,000 men, 40,000 women, and more than 20,000 men who have felonies and want to mine, and the fields under the Tuntian Corps have more than 4 million mu, which is equivalent to 20 mu for one person, of course, it is still far from the total number of wasteland mentioned by the lord, and the subordinates are still actively recruiting displaced people to open up wasteland......

Wei Yan vaguely remembered that the three counties of Yiyang were located in the same place as Nanyang, Zhumadian, Xinyang and some counties in Hubei in later generations, and about 40 million mu of fertile land was reclaimed in later generations, but now all the people have reclaimed less than 20 million mu, even if 10 million mu is left for the consolidation of water and soil, there are still 10 million mu of wasteland waiting to be reclaimed.

Shi Tao then reported on some grain planting.

Under the leadership of Shi Tao, an agronomist, the Tuntian Corps selected excellent seeds, intensively cultivated them, rotated crops, and carried out water conservancy efforts.

Of course, the recent frequent wars have had a great impact on grain production, and it is necessary to capture Jingzhou as soon as possible, and it is not easy to be affected by the wars in the hinterland of Jingzhou.

Wei Yan saw that the grain had been sown, and it was not yet the wheat harvest season, and it was idle in the farm, so he asked Shi Tao to recruit 20,000 Tuntian soldiers to help the army transport grain and baggage, and speed up the march.

After marching for two more days, he still did not encounter Cao Jun, and he was still terribly calm.
