However, Liu Cong had another thought. He felt that in the late Eastern Han Dynasty, trumpets had been used as command tools in the military. If the bamboo tube detonator was used frequently and smart people saw it, they would imitate it immediately. This would not be the case.

Beauty, it can be said that it will shoot itself in the foot.

So Liu Cong sealed the technology tightly in Hukou Au and sent close generals to guard it and closed the door for development.

By March of this year, thermal weapons like later grenades had been developed.

Just because of time constraints and limited conditions, we did not recruit casting craftsmen and did not cast the iron shell. Therefore, this Tianlei still uses bamboo tubes as the shell.

In addition, the weight is also reduced a lot, each bamboo tube sky thunder is only about one kilogram. This weight is very convenient for throwing by hand, and the effect is basically the same as the hand grenades of later generations.[

But there is one thing that technology cannot break through, that is, the hand grenades of later generations can be thrown out and explode as long as the string is pulled, without ignition. But this bamboo sky thunder cannot be used. It cannot burn and explode without ignition.

However, Liu Cong knew that such a weapon was enough to frighten the Wu soldiers and Cao soldiers and defeat them.

Therefore, Liu Cong ordered Fatty Lai Ma Gan'er to go to Hukou Pass and bring back a thousand bamboo thunders in advance, preparing to use these thunders to scare Lu Xun into pissing his pants, so that he could use his strategy to subdue him.

At this time, Liang Zhu'er led fifty men and horses to the Yangjiao Ridge. Liu Cong was at the foot of the mountain, leading Wei Yanlai's fat man Ma Gan'er to attack Wang Sheng's ordinary generals, and they were observing the situation on the battlefield intently.

Seeing that Liang Zhuer had already climbed onto Yangjiao Ridge and started to approach the first line of deer wood, Liu Cong burst into laughter and shouted to the Wu soldiers on the ridge: "Wu soldiers on the ridge, listen, run away now."

Late, if you don’t run away quickly, thunderbolts will explode from the sky in a short while, killing you all together.”

The laughter and shouting were very majestic, like thunder, and the echoes echoed in the mountains. The soldiers of both armies above and below the ridge could hear it clearly.

Wu soldiers at each pass looked up at the sky after hearing this. They saw the sun shining brightly in the blue sky, with almost no clouds at all. Where did the thunder come from?

So they didn't care. They just stared at Liang Zhuer's group of troops and laughed in their hearts: "More than fifty Jingzhou soldiers just want to come over and conquer the pass. They are really wishful thinking. Haha, isn't this asking for death?"

As they were thinking and talking like this, they saw Liang Zhuer and the others approaching the first pass and entering the range of the crossbow. The Wu Bing officer behind Luchai closed the door and ordered the arrows to be fired: "Several rows of arrowheads passed by and knocked them down. Big

The governor said that Jingzhou soldiers must not be allowed to approach the pass!"

So the first wave of arrowheads flew out of Luchai. The arrows traveled as fast as meteors. Hundreds of arrowheads left the string almost at the same time. They were crowded together like a dark cloud and made a sliding sound of "chirping..." and shot straight towards Liang Zhuer and the others.

.

He was speaking slowly, but his arrows were moving too fast. No, at this moment they were already above the heads of Liang Zhu'er and the others, and they were drilling into the Jingzhou soldiers with deadly strength.

However, Liang Zhuer and the others were not fools. When they came to the pass and saw that they were within the range of Wu Bing's sharp arrows, they immediately raised the cowhide shield as big as an umbrella above their heads.

At this time, the shield came into play, and hundreds of arrowheads hit the cowhide shield with a chaotic "bang bang bang bang bang bang" sound, and fell to the ground one after another, without even injuring a single hair of the Jingzhou soldiers.

The Wu soldiers behind Lu Chai continued to fire arrows. Although the arrows rained down like rain, they never caused any harm to Liang Zhuer and the others.

Seeing that the first Luchai Pass was already within the distance of the thunder, the arrows above his head kept shooting down, making the bang bang bang bang bang sound of the shield become more and more loud. Liang Zhuer smiled and ordered: "

Lean a little closer, lean a little closer. I see that the Wu soldiers can't throw cannons and rocks at this time! Move a few more steps closer, stay there, and listen to my orders!"

The soldiers held up their shields and advanced for more than a dozen steps. Liang Zhuer then ordered: "Hold down, stop! Get ready, light the fire!"

Watching the first group of soldiers lighting the fire, the fuse hissing, braving the dazzling electric light, Liang Zhuer ordered: "Get ready. Throw!"

Ten thunderbolts drew arcs in the sky and crowded together, trying to fly behind Lu Chai.

After the first group of ten thunderbolts flew in the sky, Liu Cong ordered the second group to be lit and thrown, and then the third group was lit.[

In this way, thirty thunderbolts fell one after another on the Wu soldiers' formation behind Lu Chai.

To be honest, not to mention Wu Bing, all the soldiers and horses in the world at that time, whether it was Wu Bing, Cao Bing or the earlier Yuan Bing, Xiahou Bing, Xiliang Bing, counting back, no soldier has seen anything like this since ancient times.

Weapons fell from the sky with sparks, and even after falling, they still emitted sparks and made a sizzling sound.

The Wu soldiers were curious, so they picked it up from the ground and observed it carefully with both hands.

Haha, that is to say, they only had to hold it up and observe it for a second or two. The sky thunder did not allow them to observe it. With a bang, smoke and dust billowed, bamboo fragments flew everywhere, flesh and blood splattered, and most of the Wu soldiers were blown out.

The deer firewood was thrown onto the wood, rocks, and grass and shrubs everywhere.

A burst of black smoke rose up like a black mushroom, rising up into the sky.

Suddenly, not a single one of the hundred Wu soldiers at the first sword pass was left who could speak; not to mention anyone who could talk, not even one who could breathe was left behind.

The Wu soldiers at the second pass about 200 meters behind were frightened. From the officers to the soldiers, no one stood there dumbfounded and couldn't recover.

Liu Cong didn't give them a chance to recover at the bottom of the ridge, and loudly ordered Liang Zhu'er: "Zhu'er, good job! Advance to the second pass, just do it like this!"

Liang Zhuer led his troops to blow up the second pass again, and then the third pass.

When heading towards the fourth Luchai pass, there were only ten sky thunders left in his hand. Liang Zhuer was more capable of killing and thought of using ten more sky thunders to conquer the fourth pass.

Liu Cong was directing the gongs below, and after a burst of gong sounds, Liang Zhuer reluctantly led the team back down the Yangjiao Ridge.

In this attack, Liang Zhuer and the fifty Jingzhou soldiers he led escaped unscathed and safely retreated to the foot of the mountain.

However, the three passes of Wu soldiers were conquered, and the three hundred Wu soldiers were suddenly wiped out and went up to heaven with mushroom clouds to enjoy their happiness.

What's interesting is that after the Wu soldiers who were behind all the way to the eight passes of Yangjiao Pass came to their senses, they all scrambled to escape back to the pass.

In fact, Lu Xun had already seen the power of this sky thunder when he was at the gate. At this time, he was not only frightened and frightened, but also extremely suspicious. He just didn't understand how Liu Cong's Jingzhou soldiers guided the sky thunder to explode on the ground under the clear sky and broad daylight.
