The total strength of the Shun army was more than 200,000, half of the army was stationed in Tongguan to block the way of the Ming army, more than 50,000 people were guarded in the area of Daqingguan and Puzhou on both sides of the Yellow River, and the rest of the army was scattered in Xi'an and other prefectures and counties in Shaanxi.

The strategy of the Shun army was to rely on the natural danger of the Tongguan Yellow River to block the attack of the Ming army. And Tongguan and Puzhou Daqing Pass are both inmissible. If Tongguan is lost, the Ming army can go straight to the pass from Henan Mansion, and if the Ming army crosses the Yellow River from Puzhou Daqing Pass, it can go around to the back of the Tongguan Shun army, and then the 100,000 Shun army in Tongguan will encounter the Ming army's front and rear attack.

The terrain around Tongguan is really dangerous, and the Shun army has a lot of troops, so Chen Yue's strategy is to feint to attack Tongguan, but the real main direction of attack is in Puzhou.

Li Guo is also very clear about the current situation, when the news of the loss of Puzhou came, Li Guo was shocked, but he could not send troops to reinforce Daqing Pass. Because the commander of the Ming army, Qi Wang Chen Yue, is now opposite Tongguan, and the Ming army opposite Tongguan is extremely powerful, which can be seen from the powerful artillery bombardment of the Ming army alone.

"Father, we must solve all the way to the Ming army as soon as possible to recover the decline." Li Laiheng solemnly suggested to Li Guo.

According to the current situation, as long as any place is broken through by the Ming army, what awaits the Shun army will be a danger of destruction!

Li Guo's expression was equally solemn: "In your opinion, where should we break through?" ”

Li Laiheng pointed to the map and said: "Father, please see, the Ming army attacked from Tongguan and Puzhou in two ways, and the Ming artillery in Tongguan looked vicious, but in fact, the Ming army only used artillery, and had no intention of taking the initiative to attack. This is not the case in Puzhou, which is guarded by 10,000 soldiers, but it can't hold out even a day under the attack of the Ming army, which shows the strength of the Ming army in Puzhou. From the front line, the number of Ming troops in Puzhou reached as many as 100,000. It can be seen that the real main force of the Ming army is in Puzhou, and we are just a partial division of the Ming army on the opposite side, but Chen Yue deliberately sat in Tongguan to confuse us.

Previously, when we were in Luoyang, the attacking Ming army was more than 30,000 people, plus the Ming army in Henan, the child estimated that the Ming army on the opposite side was more than 50,000 people, so as long as we can defeat the Ming army on the opposite side, we can thwart the Ming army's offensive! ”

Li Guo frowned slightly: "It's simple, but you have to know that the combat strength of the Ming army on the other side is very strong, at the beginning in Luoyang, we were defeated one after another under their attack, how difficult it is to defeat them?" ”

Li Laiheng said confidently: "Father, I have analyzed that the reason why the Ming army on the other side is so powerful is that their firearms are too powerful, and whether it is artillery or firearms, they are far stronger than us.

However, firearms also have their own flaws, that is, they are not easy to use on rainy days. As far as I can see, the weather has been very gloomy these days, and there is a high probability of a heavy rain. On a rainy day, the Ming army firearms could not be used, which was a great opportunity for us to defeat them! ”

After thinking about it carefully, Li Guo nodded heavily in agreement with Li Laiheng's suggestion.

The sky was getting more and more gloomy, and thick dark clouds were piling up over Tongguan. Looking at the gloomy sky, Chen Yue frowned, if it rained heavily, it would greatly affect his plan.

"Lord Wang, I'm afraid it will rain soon." Li Yan looked directly at the dark clouds in the sky and reminded.

Chen Yue sighed: "Order to suspend the shelling, and order the whole army to prepare for the rain." ”

Li Yan nodded straight and passed the order down.

In the afternoon, the sky was indeed raining, and a gust of wind blew, crackling and pouring rain. The rain was so heavy that the rainwater on the ground gradually merged into a single piece, forming a stream in the low-lying areas, carrying mud and soil with it, rolling towards the Yellow River in the north.

Fortunately, when the camp was established, the choice was on the hill of the high post, although the rain was heavy, it did not have much impact on the camp for the time being. The soldiers hid in the tents, but there was no risk of rain, and although the dampness in the simple tents did not prevent them from resting.

Tongguan, looking at the storm, Li Guo and Li Laiheng father and son were relatively speechless, such a heavy rain, it was difficult to walk in the rain, and it was impossible to send troops to attack.

"Tell the brothers to get ready, and wait for the rain to light up a little before sending troops." Li Guo sighed and commanded.

However, until dark, the heavy rain did not stop at all, and Li Guo's plan to take advantage of the rain had to be shelved.

It rained heavily all night and turned into a drizzle the next morning. However, looking at the rushing water in the mountain col, Li Guo was worried again. After a night of heavy rain, the water rolled down the mountains to the south and flowed down the ravines, forming countless streams, and the high hills, the ground was also soaked and softened, and it was impossible to walk normally. In such a situation, it is really difficult to send troops to attack.

"Father, don't hesitate! Take advantage of the rain to send troops, miss this opportunity, and then try to annihilate the Ming army, I'm afraid it will be impossible! Lee Rae-hyung pleaded.

"But in this situation, it is difficult to even march normally, how can you trek for miles to attack the camp of the Ming army?" Li Guo was embarrassed.

"Father, it is precisely because of this that the Ming army never imagined that we would attack, so it can have a surprise effect!" Lee Rae-hyung insisted.

Li Guo thought about it again and again, and finally agreed to Li Laiheng's plan, and assigned half of his troops to Li Laiheng, so that he could lead the general attack on the Ming army's camp.

Chen Yue and Li Yanzhi really didn't expect that the Shun army would take advantage of the rain to attack, but the camps of the Ming army were all set up on the high plateau, there were soldiers who were specially guarded and sentry, and there were bucket arrow towers in the camp for lookouts.

Hearing the news that the Shun army was attacking while it was raining, Chen Yue was stunned for a moment and smiled.

"Lord Wang, there are also capable people in Shunying, who know that heavy rain is not conducive to the play of firearms." Li Yan said with a straight smile.

Chen Yue sighed slightly: "It's a pity that Li Guo and the others are just thieves from peasants, their vision is too narrow, and there are many things in this world that they don't know and can't imagine." ”

Wading through the water and stepping on the mud, about 50,000 Shun troops went out of the pass to attack the Ming army camp, and the journey of seven or eight miles took an hour, and the vanguard troops arrived outside the Ming army camp.

As Li Guo and his son guessed, the firearms of the Ming army could not be used at all in this weather, whether it was the huge number of artillery of the Ming army or the sharp firearms, there was no sound when the Shun army approached, and the soldiers of the Shun army were allowed to approach the camp.

Seeing that the firearms of the Ming army were useless, and his army was equipped with a large number of bows and arrows, Li Laiheng, who was in charge of the command, was overjoyed, and looked at the Ming army camp in front of him, as if he saw the hope of defeating the Ming army.

"Brothers, attack!" With Li Laiheng's order, the drums sounded, and groups of soldiers of the Shun army rushed towards the Ming army camp with shouts.
