Chen Yongfu touched the short whisker of his chin and thought for a while, before he asked uncertainly, "You don't want to use water attack, do you?" ”

Because he knew that a sneak attack was not very likely. There are large paddy fields in front of the defense line, and only a few land routes can be crossed. However, it is the key place for the artillery to break in, and even if the soldiers are lurking past, as long as they ignite the fire medium to ignite the bomb, it is easy to be discovered by the enemy. If he sneaks directly into the enemy's defense line, and the two sides are close to each other, it can only be a life for a human life, even if he is a halfway monk, he knows that this kind of loss-making business cannot be done.

"Where's the time?" Zhou He shook his head: "Didn't you just send us fifty spontaneous fire bombs today?" Just let the troops sneak to about twenty paces away from the enemy and drop bombs into the line of defense. When the intruding army is blown up, the follow-up troops will follow. Then let our two trebuchets fire at full force into the enemy's rear to block the enemy's reinforcements. As long as you can take the enemy's first line of defense, the rest is easy to say. After all, they have sandbags in front of and behind their defensive lines, and we can use them conveniently. ”

Chen Yongfu was stunned for a moment, and stopped: "Isn't that spontaneous fire bomb here for us to try?" Whether it can be used is still a question, and if it is used at such a critical time, there is a little problem, and it will not make the soldiers suffer casualties in vain. ”

"Since it can be sent to the troops, there will be no problem." Zhou He is very confident in the reliability of the weapon: "Let us try it, not to let us test whether it can be used, but to see if there are still those deficiencies that need to be improved." If there is a problem with the safety of the bombs, it is impossible to bring them to the troops, and each batch will be sampled. ”

Chen Yongfu glanced at Zhou He, but he was still not at ease, he didn't dare to agree, he would rather attack in a more secure way after dawn. He finally got his current status, and seeing that Li Yan was about to open the country and ascend the throne and reward the ministers, now is not the time to make a mistake.

Zhou He said decisively: "This time it is under the full command of the end of the future, and General Chen is unwell and has no idea about it. ”

Having said that, Chen Yongfu couldn't object anymore, so he could only acquiesce to Zhou He's arrangement.

Just after the time of the child, Gao Yigong and others in Dangtu County also received an order from Li Zicheng to let them go south to Huzhou and attack Hangzhou.

"And what about the enemy forces behind?" Gao Yigong asked. Although he didn't want to go head-to-head with Li Yan's troops, he also felt uneasy when he always let Li Yan's team follow behind.

The colonel replied: "Your Majesty has discussed with the military advisors and the generals, and it is judged that Li Yan should not continue to go south. His Majesty ordered the Hou Ye to report the military situation to His Majesty every day, and if Li Yan continued to pursue south, His Majesty would make a decision at that time. ”

Gao Yigong was helpless, so he had to express his order.

As soon as the heralds had departed, they summoned the generals to take counsel. Originally, the generals were in a daze, but as soon as they heard the order to retreat, they were all in good spirits. Although they have been at peace with Li Yan's men in the past few days, they will start a war when they can't keep it. Now that the above has withdrawn, what are you waiting for? Let's go overnight!

As soon as the generals discussed and unanimously approved, they immediately asked the troops to pack up and withdraw overnight. So first of all, the soldiers and horses in the county town began to move, and the soldiers were all woken up and began to pack up their things and prepare for the pull. At the same time, a herald was also sent to inform the troops of the three lines of defense, especially the artillery on the first line of defense, to evacuate as soon as possible.

However, the time of their notification was a little late, and before the first line of defense was notified, the two hundred raiding troops under Zhou He had slowly climbed twenty steps outside the defense line.

The captain saw that his men were ready, and the follow-up troops were fifty paces behind them, and as long as they could rush into the defense line of the intruding army, the follow-up troops would immediately rush up to support.

The captain patted the back of his subordinates in front of him, and his subordinates understood, and immediately pulled the bomb ring at hand hard, and the exposed lead immediately burst into flames. He breathed a sigh of relief in his heart, and finally didn't have to worry about igniting the lead with an open flame to expose it in advance. He immediately grabbed the rope of the bomb and threw it up, and then threw it into the line of defense with all his strength.

The bomb arced through the air, flew in just between the roof and the sandbag, and exploded with a bang a few moments later. The intruders in the defense line immediately became chaotic, shouting the enemy attack with all their might, while those who slept were panicked after being awakened, and could not form an effective counterattack at all.

The captain smiled and said, "This tap fire really works, brothers, hurry up and beckon inside and grab this section of defense." Otherwise, in a while, we'll have to eat the cannons. ”

When his soldiers heard the command, they hurried forward, or handed the running fire bombs they were carrying to their comrades in front. As soon as the ring is pulled hard, the lead of the bomb is ignited, and then it can be thrown into the enemy's defensive line. Explosions followed, as well as cries of panicked and wounded enemies.

The key to this pull-fire bomb is on a fire-pulling tube. A copper tube is wrapped around the lead head, and the inner wall is coated with flint powder. The pull ring is wired and connected to a small ball made of copper wire. Flint and steel can not only spark when it hits, but also when it rubs vigorously. Therefore, the copper wire ball rubs against the copper pipe, so that the flint powder on the inner wall burns, and the lead can be ignited.

This was discovered by the craftsmen who mined and cut the flint, and when this discovery was finally inadvertently known by Wang Renhui and others, they had the idea of using flint powder to light the lead. After countless trials, they finally found the right solution. Some of the new guns have had their ignition holes modified to fit the size of the ignition copper tubes. If the effect is good, in the future, the ignitor will not always have to carefully watch whether the fire rope is extinguished, whether it is time to adjust the length, and the gun fire will become easy and safe.

After the rumbling explosion, while the invading army was still in chaos, the raiding troops all rushed into the invading army's defensive line. Spearmen and sword and shield men formed a defensive line on either side, and the soldiers behind threw bombs at the enemy, while others fired crossbow arrows, and began to expand to the sides, allowing the following large forces to follow.

The trebuchet was also carried by the soldiers to the breach, which was the dead end of the enemy's artillery. They quickly assembled the trebuchet and fired fire canisters at the enemy's second line of defense, blocking the enemy's reinforcements.

However, their fire pots were basically in vain. As soon as their attack began, the heralds of the intruding army sent the order to retreat. Therefore, all the invading troops on the front line knew the order to retreat, and all of them fled as fast as possible, and no one cared about the artillery that Shi Jin had specifically told to give priority to retreating. Hundreds of pounds and thousands of pounds of things, only fools can flee for their lives.

A seemingly risky sneak attack in the dark was an easy success.
