However, Shang Yi did not have many cavalry at hand, so it was impossible to learn from Napoleon's tactics, but directly adopted the artillery and infantry combined with offensive tactics commonly used in later generations, which is the so-called firepower extension tactic.

Fire extension refers to using artillery fire to open the road in the front and clear the obstacles, while the infantry follow behind to clean up the results of the battle. The landing point of the artillery fire is always at the front of the infantry's attack. Therefore, the accuracy of artillery fire and the coordination between artillery infantry are required to be very accurate. This tactic was formed in the late 19th century and gradually matured and improved by World War II, and it also became the mainstream tactic on the battlefield. Until Shang Yi came to this era, the role of artillery was mostly replaced by air strikes.

Now the technical level of merchants' military artillery has exceeded this era. Although it cannot be very accurate, it can also initially meet the requirements of firepower extension. Shang Yi has also considered introducing firepower extension tactics, but he has not had time to cooperate with the insurgent artillery. Today, there was a sudden light of inspiration on the battlefield and found that it was an opportunity to test this tactic.

Of course, it is indeed a bit of risk to use this tactic on the battlefield because it has not undergone special training, but the Qing army has not experienced this tactic. In addition, Shang Yi is still very familiar with the tactical theory of firepower extension, so he decided to give it a bold attempt. After all, fighting is a risky thing, and there is no war that will be fully confident before the war begins.

But this was enough for the Qing army to bear. Before the reinforcements arrived at the battlefield, they were beaten up first, causing chaos in formation. Although the current force is nearly four times that of the merchant army, unless the merchant army can be surrounded, these more than 35,000 people will not be able to be held together. Moreover, although the merchant army also uses column tactics, the front is still stretched and it is impossible to completely surround it. Therefore, only two or three thousand people in the front row can be truly able to take over the battle with the merchant army.

If the Qing army had a complete formation and had rules and regulations on the operation and command, it could also be replaced by rotation and joining the battle in turn, consuming the strength and physical strength of the merchant army with the advantage of the number of people. However, the formation of the Qing army is now in chaos, and many middle and lower-level officers were killed by blockers, making it difficult to form an orderly rotation and could only fight on their own. As a result, although the Qing soldiers behind could not be said to be just here to fight, they could only wait first until the people in front died and they could make up for it themselves.

Therefore, the Qing army not only could not play its advantage in numbers, but also lined up fifty or sixty steps backwards. The back formation was constantly bombarded by the merchant army and was beaten to the point of being dazed. It was only because of the large number of people that they could not support them, but they still fought and retreated.

Duoduo could see it very clearly on the command platform, but he had no choice but to send people to help with the war, and he could only gather together. Even sending cavalry is useless, because the infantry could not give way out and could only be hit by the artillery of the merchant army as a living target. Now he can only hope that the Qing army can adjust itself in battle, and in addition, it will consume the strength of the merchant army. He led the merchant army away from the attack range of artillery. When his troops were slightly looser, he would send cavalry to charge and defeat the merchant army in one fell swoop.

In fact, Shang Yi knew very well that the Qing army was only able to withstand the force of force now, and after a long time or if he invested his troops, he could defeat the Qing army. However, Shang Yi hoped to use the cover of the battlefield to push the artillery as much as possible before he did not join the reinforcements. At this time, the artillery of the Shang army was also gradually advancing under the command. The artillery positions on the front line advanced by another hundred steps, always hitting the artillery shells into the Qing army's rear team, and in the main formation

At this time, the 14th Regiment, which rescued the people, had completed the task, reassembled and prepared to participate in the war. Liu Zhaoji, Zhuang Zigu and other 10,000 Ming troops were also eager to try. Shang Yi had been calculating the distance, and ordered sixty heavy artillery to launch the position, advance 200 steps forward, and attack the main formation of the Yan army. The thunder rockets in the front-line artillery position began to extend the attack on the Qing army's artillery position, and at the same time ordered the 14th Regiment and the Ming army to attack, replace the Third Regiment, the Ninth Regiment and the Foreign Mercenary Regiment. He also ordered an auxiliary battalion to send a batch of grenades to replenish his ammunition.

At this time, at the other end of the battlefield, Duoduo's mind was in a mess, and he didn't know what to do. Although the smoke of gunpowder on the battlefield blocked Duoduo's sight, he also found that the merchant army was increasing its troops into the battlefield and also pushed the artillery forward. However, the generals were talking about how to deal with the merchant army's attack. Geng Zhongming suggested firing artillery to attack the merchant army, but Ye Chen believed that the attack should be added. Bai Yitu felt that cavalry could be dispatched, bypassed from both sides of the battlefield, and attacking the artillery positions of the merchant army.

Duoduo felt that every suggestion seemed to make some sense, but it was not an emergency measure: firing artillery and the merchant army, but who should I attack? The number of merchant army is small now, so the depth is much smaller than that of the Qing army. The Qing army's artillery is not so accurate. It can hit the artillery position behind, but the gunners cannot see the position clearly through the battlefield in the middle; the forces joining the attack are even more random, and now there is a crowd of people, which is useless; sending cavalry to attack the artillery position, Duoduo was a little tempted, but now the battlefield is more than 300 stairs, how far does the cavalry have to go around to reach the artillery position of the merchant army? Moreover, the merchant army also has cavalry, what should I do if I intercept myself halfway.

Therefore, Duoduo felt as if he was too big to fight and didn't know what to do. He couldn't help but regret it secretly. If he had listened to Hong Chengchou's advice, he would have withdrawn. He looked at Hong Chengchou again and found that he was at a loss, because it was the first time Hong Chengchou had experienced such a war scene, and now he really didn't know where to start.

However, Hong Chengchou also knew that he had to make a quick decision on the battlefield. He was hesitant and could only miss the opportunity to fight. Therefore, he was about to suggest that he use artillery to fight against the merchant army first. At this moment, with a "boom", a thunder rocket fell into the Qing army's artillery position and exploded. Then the second, the third, dozens, and hundreds of them fell into the artillery position.

This time, the merchant army launched nearly a thousand thunder rockets in one breath, covering almost all the artillery positions of the Qing army. For a moment, the Qing army's artillery positions were almost full of explosions.

The explosion power of the Pili Rocket is actually not as powerful as that of artillery shells, and the Qing army's artillery can be protected by wooden fences. The Qing army's casualties are not large. However, the Pili Rocket is defeated by a large number and has the characteristics of combustion. The wooden fences originally used to protect the Qing army have become an excellent combustion object. Once the tincture oil splashes on the wooden fence, it will immediately spread and burn. Although the Qing army's gunners tried their best to extinguish the fire, the fire was extremely scattered and the tincture oil burned, which could not be extinguished in a short period of time. Moreover, new Pili Rockets are constantly joining.

But this is nothing. What's even more terrifying is that the artillery positions are everywhere, and many gunpowder barrels have been opened. Once the fire spreads to the gunpowder barrels, it inevitably triggers a big explosion. Therefore, after a while, the artillery array heard the continuous "boom-boom-boom-boom-boom-" loud explosions, and the earth trembled. The flames of Shengteng rushed straight to Yunxiao. The Qing army's gunners, artillery, wooden fences, cannons and other items were all blown up.

In fact, the entire transformation time was not long, just a few minutes, but the Qing army's artillery position became a sea of ​​fire. The surviving gunners dared to stay in the position and fled backwards. Even Duoduo, Hong Chengchou and others, who were more than a hundred steps away, felt the heat waves and the smoke was choking. They were all shocked.

Duoduo looked at the artillery position that had been completely destroyed, and at the same time he felt heartbroken. More than 140 artillery pieces, including more than 50 of them, were red-clothed cannons. They were completely destroyed, and he couldn't help but stamp his feet and beat his chest in anger, and he was furious."

Geng Zhongming hurriedly said, "Prince Yu, this place is too dangerous, so we should withdraw quickly."

After hearing this, Duoduo turned around and kicked Geng Zhongming, and said sternly: "Retreat? No one is allowed to retreat now. Send orders to continue, and the entire army will attack and fight against the merchant army."

Geng Zhongming was stunned and said, "Prince Yu, you can't continue to fight anymore, withdraw."

Duoduo grabbed Geng Zhongming and said sternly: "If you dare to withdraw again, I will kill you. I will immediately give me an order to attack the whole army..."

Before he could finish his words, he heard a "boom" sound, and a shell fell four or five meters away from the command platform and exploded. The splashed soil splashed on everyone's body. Then countless shells fell into the Qing army's formation, only causing sand and stones to fly, and the sky was dark.

Hong Chengchou hurriedly said, "This place is too dangerous, let's step down first."

This time, Duoduo was not forced. According to Hong Chengchou's advice, he hurriedly got off the command platform with the generals and then horsed each other. At this time, nearly a hundred shells had fallen in the Qing army's position. The Qing soldiers were all running around, looking for a place to hide, and the scene was very chaotic. When Duoduo wanted to reorganize his troops, he saw that the Qing army on the battlefield had retreated.

Because the merchant army always maintained good order during the battle, after the 14th Regiment and the Ming army joined the battle group, the two troops successfully changed, and the Third Regiment and the Ninth Regiment retreated and temporarily repaired. The 14th Regiment and the Ming army also launched a fierce attack on the Qing army again.

This group of people were all new forces. Of course, it goes without saying that the combat effectiveness of the 14th Regiment was, even the 10,000 Ming troops had accumulated enough breath since the previous few days. Now they finally had the opportunity to fight, so naturally everyone fought bravely and acted very fiercely. At this time, the Qing army was only able to avoid support with a large number of people, but the one who could withstand this fierce rush and attack immediately became defeated. When the Third Regiment, which had just retired from the battle, saw that the Qing army was defeated, he ignored the rest, but each of them added a few grenades, and then the horses went into the battle.

When Shang Yi saw that the Qing army was defeated on the battlefield, he immediately ordered the artillery on the front line to stop firing, so as not to accidentally injure his own people and to pull all the artillery back to the position. At the same time, he ordered the cavalry brigade to attack and participate in the battle and take advantage of the situation to pursue.

The defeated Qing army retreated to its original formation. Although the main formation of the Qing army was disrupted by the artillery of the merchant army, after Duoduo's strict order, the two sides started a fierce battle. At the same time, the heavy artillery of the merchant army extended its firepower again and shot the shells at the rear of the Qing army. More than 100,000 Qing army were all put into battle.
