As night slowly descended on the battlefield, the battlefield that had been lively all day became quiet.

At the gate of Mushroom Yu City, hundreds of tigers and leopards are holding shovels in their hands, like ghosts in the night, coming out of the city gate. Then, along the communication ditch between the trenches and the trenches, quickly touch the third line of defense closest to the enemy.

Hundreds of men started at the same time, digging communication ditches from the first line of trenches of the third line of defense to the position where the Tartars were located. When the communication ditch extends to a distance of more than ten battles from the Tartar position, immediately stop digging forward. Turning the direction, extending to both sides of the communication ditch, digging a slender trench large enough for the Tibetans at a distance of more than ten zhang from the Tartar position.

Hundreds of people were digging forward at the same time, building trenches, and such a large movement could not be kept secret in such a quiet night.

Therefore, the Haw Par Army's digging trenches to prepare for a counterattack had just begun, and the Tartars could faintly see the busy figure of the Haw Par Army under the reflection of the bonfire in front of the position.

Finally occupied the two lines of defense of the Tiger and Leopard Army, how could the Tartars watch the position fall into the hands of the Tiger and Leopard Army again.

As a result, as soon as the figure of the tiger and leopard army appeared in front of the Tartars, hundreds of arrows were shot by the Tartars, and after drawing beautiful silver lights in the night, they flew towards the location of the tiger and leopard army with a whistling sound.

In the case of direct aiming and archery at night, it is difficult for the Tartar archers to hit the target, not to mention that the Tartars can only use their bows and arrows to shoot without the slightest accuracy.

Therefore, in the face of the rain of arrows shot by the Tartars, hundreds of tiger and leopard troops did not even dodge, and continued to wave the shovels in their hands and extend the trench under their feet towards the Tartar position.

After three hours of tumult and continuous excavation, a slender trench finally appeared more than ten feet in front of the Tartar position. Not only that, but the tens of thousands of arrows fired by the Tartars at the Tiger and Leopard Army at night were also densely inserted into the position, and as far as the eye could see, the huge position was like a hedgehog that had been covered with spikes, which looked extremely hideous.

"The trench is finally finished, and the end of the enemy has come...... Order the bombardiers, take the grenades, and set off at once, ready to drop bombs on the Tartar positions, and let them taste the true power of our grenades......"

"The musket regiment, two spear battalions, commanded by Commander Wang Fengwang, immediately enter the third line of defense and prepare for a counterattack." A sneer quickly flashed at the corner of his mouth, and Wei Zheng, with a murderous face, ordered.

Five grenades for one person, and fifteen hundred grenades for three hundred bombardiers.

In the idea of the guard, in the trenches where the infantry and Tartars were densely gathered, even if one grenade only killed two enemies, 1,500 grenades could bring destruction to 3,000 enemies in a short time.

With the loss of 3,000 troops in the blink of an eye, no matter how high the enemy's morale is, it will be blown up by this grenade.

When the time comes, in the face of more than 1,000 officers and men of the Tiger and Leopard Army who participated in the counteroffensive, the remnants of the enemy, not to mention counterattacking, may have completely disappeared even the most basic fighting courage, and fled directly on the battlefield.

When Wei Zheng was reverie about the battle that was about to begin, three hundred bombardiers were already standing on the front line of the trench with grenades.

Holding a grenade with an exposed fire rope in one hand and a fire breaker that had already been lit in the other, he waited quietly for the order to attack.

At the signal of Wei Zheng, a cannon mounted on the city wall suddenly sounded a cannon that represented the order to attack.

Under the gaze of Wei Zheng, the moment the cannon sounded, the fast-reacting bombardier had already lit the grenade rope with a fire fold. When the sparks burning at the end of the arquebus disappeared from the wooden handle of the grenade, the bombardier quickly raised his arm and threw the grenade with white smoke from the wooden handle.

Three hundred grenades broke free from the restraints of everyone's right hands one after another, and with a whistling sound, they crossed the distance of more than ten zhang between the two armies, and fell into the Tartar position as if it were raining.

After the violent explosion sounded on the front line of the trench, it was mixed with a large amount of black smoke and blood mist, and even the fireball of the enemy's stump and broken arm quickly sprung up on the front line of the trench like mushrooms after a rain.

The explosions had not stopped, and the second round of grenades thrown by the three hundred bombardiers had already arrived, appearing over a trench in a sea of fire.

In the next tea time, the Tartar positions were filled with the sound of violent explosions that kept ringing, which was the storm of death brought to them by the explosion of the grenade......

As the loud explosions slowly subsided, the trench, which had just been overcrowded, had turned into a hell covered with the corpses of Tartars and infantry henchmen. Not only that, all kinds of stumps and broken arms and internal organs that were shattered by grenades also covered the entire trench, so that the entire trench was covered with a thick smell of blood and gunsmoke.

In the midst of a dense group of enemies, the explosion of a grenade produced a huge force far beyond Wei Zheng's imagination.

If nothing else, the first line of the trench was full of a layer of enemy corpses, far more than two thousand. What's more, the line of the earthen wall outside the trench is also covered with a dense layer of corpses.

When more than 1,000 tigers and leopards rushed to the Tartar position, they were left with corpses, a few lightly and seriously wounded. As for the few uninjured Tartars, they were stunned by the tremendous power of the grenade explosion, and remained motionless in the face of the spears of the tiger and leopard army stabbing into their bodies.

The whole night raid went much smoother than expected, and it started and ended quickly. Wei Zheng and the others standing on the city wall had not yet reacted, and the cheers of victory in the battle had already sounded on the battlefield.

"Won, we won...... How long did it take for us to win...... General, the power of this grenade is too great......" Zhou Shuyuan said with a stunned face.

Zhao Yun, who was standing behind him, was even more direct, and shouted loudly: "General, the power of the grenade is too great, just over a thousand grenades can send thousands of enemies to the western sky." If all the tens of thousands of grenades sent by the Bar Soldier Workshop were thrown into the Tartar barracks, the tens of thousands of troops under Commander Dolgon would be sent to the western heavens by us..."

"Yes, General, take advantage of the victory and attack directly, launch a counterattack directly against the Tartars, blow up their barracks with grenades ..."

"We have grenades, and we will definitely blow up the battlefield to the ground..."

Military advisor Zhou Shuyuan was also moved at this time, and said thoughtfully to Wei Zheng: "General, what everyone said is very reasonable....maybe we can really use a grenade to create a miracle..."

"Create a miracle with a grenade, counterattack directly against the Tartars, and completely grasp the initiative on the battlefield..."Wei Zheng's eyes lit up, and he muttered to himself.
