History: Great Qin Empire, September of the 27th year of the First Emperor. Chen Sheng, the county guard of Minzhong County, led an army of 20,000 troops, set off from Dongye, went south along the Jiulong River, and waved his army to South Vietnam.

Minzhong is adjacent to South Vietnam. And the terrain is more peaceful than in other places. Therefore, the 20,000-strong army and the 5,000 logistical civilians accompanying the army smoothly entered South Vietnam. Moreover, due to the desolate location, the armies of the South China Sea were holding the main passes, and almost no important resistance was encountered along the way, so they were occupied. However, Chen Sheng said with a heartfelt voice: "Our troops are already small, if we divide our troops again, we don't have to fight with the enemy, and in the end we all have to be single commanders, and it is more convenient for us to concentrate our military strength to fight." ”

Li Zuoche was worried that if the back road was cut off, the army's grain and grass would be unsustainable, and he would fall into a predicament like hundreds of thousands of troops marching south.

Chen Sheng patted Li Zuoche on the shoulder and said: "This is even more worrying, the grain and grass we carry with the army is enough for us to support two months, before leaving, I ask Su Yun to mobilize the Ling family's fleet to help, our grain and grass will be transported from the coast of central Fujian, our grain route, not on land, but at sea." I want to come to the kings of the South China Sea, but there is no navy, right? ”

With Chen Sheng's assurance, Li Zuoche settled down in his heart. Chen Sheng's way of marching and fighting was completely different from Li Zuoche's. Li Zuoche's combat concept was to fight steadily and steadily, step by step, and gradually encroach on the enemy's strength. And a very complete scheme was proposed for this. Even if this operational plan is submitted to the supreme commander of the Southern Expeditionary Army, General Ren Huan, I am afraid that it will receive great attention. But Chen Sheng only glanced at it a few times and vetoed Li Zuoche's proposal. and threw out a combat plan that made Li Zuoche almost collapse madly.

This plan is: assault Longchuan.

From the information sent back by the Heishui Pavilion in the South Vietnam zone, it is known that the garrison of Meng Heilong, the largest soil king in South Vietnam, is nearly 100,000 here. Meng Heilong once defeated Tu Ju here, drove the Southern Expeditionary army back to Nanye, and then used the garrison here as a large rear to counter the Southern Expeditionary Qin army.

Chen Sheng saw at a glance the importance of Longchuan's geographical location.

controlled Longchuan, and stifled the southward movement of the Qin army. The Tunjun Longchuan was able to control the Hengpu Pass close to Nanye, the Yangshan Pass and the Huangxi Pass in Jiuzhi to the greatest extent. Outside Hengpu Pass, Zhao Tuo is still struggling to lead the army to knock on the pass, and Yangshan Pass, Ren Huan is personally struggling to tackle the fortifications, but it is still fruitless. This is the place where Longchuan is supporting the two places, and a large number of soldiers are carrying heavy loads from here to the pass. And Chen Sheng rushed to attack Longchuan, there was another reason. If he didn't capture Longchuan, he wouldn't be able to gain a firm foothold in Lingnan, and even if the Ling family's fleet could deliver military rations along the coast, there would be no way to transport it to land. It is impossible to build a strong point of support for the war. He, Chen Sheng, could only lead an army of 20,000 to fight guerrillas.

In mid-September, the 20,000-strong army of Minzhong County had advanced to the vicinity of Longchuan.

……

Meng Heilong has been a little restless in the past few days. Since defeating Ruotu Ju, his strength has risen dramatically. The kings of the land in all parts of the South China Sea respected him and fought against the Great Qin. With the expansion of his strength, he is also a little proud, especially when the offensive of the Qin army has weakened recently, and his focus has gradually shifted from resisting Qin to the matter of establishing a country and sealing the king. Meng Heilong was not satisfied with being just a small barbarian king. As a barbarian king, he still yearns for the state system of the Central Plains. He understands better that at this time, there will be less resistance. The earth kings everywhere also counted on him to be the main force against Qin, even if his requests were more excessive, they would accept them.

So while leading the army to defend Longchuan, Meng Heilong did not forget to order the barbarian kings belonging to all parts of the country to pay tribute to treasures and money, prepare for the construction of Panyu Palace, and prepare for his dream of founding a country. Of course, after he became king himself, the barbarian kings under him would naturally get the benefits they deserved. He even promised that after the defeat of the Qin army, he would go north and plunder the goods, beauties and people of the Qin people, and reward them to all dependents.

After receiving all kinds of promises and benefits from Meng Heilong, many earth kings willingly joined him. Of course, there are also some earth kings who are not willing to belong to him, Meng Heilong secretly hated in his heart, thinking that as soon as the Qin soldiers retreated, he would destroy all these unknown guys and establish a big South China Sea Kingdom. Speaking of this, Meng Heilong was still vaguely grateful for the invasion of the Qin army, if it weren't for the huge threat of the Qin people, the Yue barbarian kings everywhere, which of them didn't fight each other and fought against each other, how could they listen to his orders?

However, in the past few days, Meng Heilong felt that the pressure suddenly increased. He received some secret spy news one after another, and a Qin army set out from Fujian and advanced into the South China Sea. At first he was not shocked by the news. Because he knew very well that Minzhong County was a new county of the Qin State, and it was simply impossible to allocate a large number of troops into the South China Sea. When he heard the news, he immediately ordered his subordinates to bring valuable gifts and quietly enter Fujian, trying to contact the former Minyue King Su Shao, in the name of helping Fu Shao restore the country, let Su Yao make trouble in Fujian, and drive the forces of Qin out of Minzhong County.

Of course, Meng Heilong's move is not a good intention, if Minzhong County is in chaos, then the Qin army will inevitably divide the troops to recruit, and then the pressure on the South China Sea will be less.

The envoys sent into the sea like mud oxen, and before the news could be returned, Meng Heilong learned that the army of Minzhong County was approaching Longchuan.

It stands to reason that there are only 20,000 Qin troops, but Meng Heilong still doesn't pay attention to it. He had fought a decisive battle with Tu Ju's 100,000 army before, but he didn't lose the wind, and he didn't pay much attention to the new army in Minzhong County.

But in fact, Meng Heilong's heart was full of palpitations. This feeling told him that the 20,000 enemy troops were not easy to gnaw. In order to prevent the Qin army from suddenly attacking his base camp Longchuan City, Meng Heilong hurriedly sent a large army to cross the Meijiang River and established two walled cities, which were horns with the finished glyphs of Longchuan City, guarding the safety of Longchuan Land. Two battalions garrisoned 30,000 soldiers. Meng Heilong gave an order to the generals who led the troops, and once they found the main force of the Qin army, they would immediately flank it and defeat it in one fell swoop.

With such a layout, Meng Heilong's heart calmed down. However, when he learned that Meng Heilong had set up two camps on the other side of Longchuan, Chen Sheng had a sinister smile on his face. Although the Meijiang River is not very wide, it always takes some time to cross the river, and if these two camps are attacked by surprise, it will be difficult for the defenders of Longchuan to arrive in time even if they want to rush to help.

"Meng Heilong is sending two camps to us." Chen Sheng said to Li Zuoche.
