Yangcheng, an inconspicuous earthen city, the whole city is made of earth and stone, although it is small, but it is extremely strong.

No one would have thought that such an inconspicuous earth city would be the lifeblood of the Mu clan in Wuxian County, and the grain and grass accumulated by the Mu clan for a hundred years were stored in this earth city.

Mu Ge, a descendant of the Mu clan, was arranged by the patriarch of the Mu clan to guard Yangcheng, the entire Yangcheng, a total of 8,000 soldiers and horses, are the elite of the Mu clan, they are well-equipped, tightly guarded, within a radius of ten miles, people are difficult to approach.

This is Li Qing got all the information about Yangcheng, Yangcheng, hoarding all the grain and grass of the Mu clan, as long as the grain and grass of Yangcheng are destroyed, the entire Bashu rebels will fall into an embarrassing situation of having no food to eat, as for the grain and grass they obtained from the city, it is not enough to support a long war, because the grain and grass of Bashu are all hoarded in Jiangzhou, as long as Ziche Zhong'an can protect Jiangzhou City, the rebels will not have a way to get enough grain and grass.

This is an extremely risky operation, Yangcheng is in the hinterland of the rebels, and there is a slight difference, and Li Qing and his party will die without a place to be buried.

Li Qing looked at Shen Baobao, this glance made the kid's body tremble, what happened last night made this young master of the Shen family, who had never experienced setbacks, afraid of Li Qing and his party from the bottom of his heart.

Shaking his head, Li Qing felt that it was really not a wise choice to pin his hopes on Shen Baobao, this kid was a little too timid.

Li Qing asked two Qin soldiers to escort Shen Baobao down, and then summoned Li Chunyang, Fan Cheng and others to discuss whether to go to Yangcheng.

Li Qing looked at everyone and said in a deep voice: "Yangcheng is hoarding the grain and grass of the rebels, according to Shen Baobao, the grain and grass in it are piled up, which is the savings of the Mu clan for a hundred years, and it is also the confidence of the Mu clan to dare to covet Bashu, we now have two choices, first, while the rebels have not found us now, immediately leave the territory of Wu County, and go to Nanjun for help, second, while Wu County does not know that Shen Baobao has fallen into our hands, we venture into Yangcheng and burn the grain and grass in Yangcheng, what do you think?" ”

Fan Cheng said first: "There are not many soldiers and horses in Nanjun, and there is no order from His Majesty the First Emperor, with our identity, there is no way to mobilize the soldiers of Nanjun, and when the soldiers and horses of Nanjun arrive, I am afraid that the rebels have already prepared, so I think we can take a risk and enter Yangcheng." ”

Li Chunyang shook his head and said: "No, Yangcheng is not as good as the camp last night, the grain and grass in Yangcheng are not so easy to burn, even if we can mix into Yangcheng, there is no way to burn all the grain and grass in Yangcheng, when the time comes, the rebels only need to close the city gate, we are wings, I am afraid it will be difficult to retreat." ”

Yes, even if you successfully enter Yangcheng, how can you burn all the grain and grass in Yangcheng? If it is just a fire, there are so many rebels, there must be a way to extinguish the fire, even if you can burn some grain and grass, it will be difficult to affect the overall situation.

Li Qing fell into deep thought, Ziche Zhong'an's current situation is very bad, all the counties of Shu County have fallen, and Langzhong and Fangmeng Pass have blocked the Qin army's reinforcements from Hanzhong, so in the entire two counties of Bashu, Ziche Zhong'an has become a lone army.

"How can you burn all the grain and grass in Yangcheng with one fire?"

Li Qing frowned, constantly recalling what he knew in his mind, trying to find a good way to set the fire.

"That's right, gunpowder."

Li Qing's eyes suddenly flashed with a glimmer of light, when it comes to arson, in addition to the traditional fire-initing things, gunpowder is definitely an artifact of ignition.

Gunpowder, as one of the four great inventions of China in later generations, its origin can be traced back to the Han Dynasty, in the Qin Dynasty, naturally there has not been such a magical thing.

Li Qing had carefully studied the production of gunpowder, and the formula of gunpowder was no longer a secret in later generations, so it was not difficult for Li Qing to make gunpowder.

Time was urgent, and Li Qing had to enter Yangcheng before the rebels knew that Shen Baobao was captured, so Li Qing did not dare to hesitate, and immediately called everyone and asked them to buy sulfur, saltpeter and other materials to use to configure gunpowder.

Sulfur and saltpeter, these things were not particularly valuable in the Qin Dynasty, except for Taoist disciples who often bought alchemy, ordinary people were rarely interested in these things.

And it just so happened that Li Qing had Li Chunyang, a Taoist priest, here, so he bought enough sulfur and saltpeter without attracting anyone's attention.

Looking at the yellow, gray-white stones that Li Chunyang bought, Li Qing's face showed excitement, although Li Qing did not have the ability to make a musket, but with gunpowder, Li Qing was able to make some simple bombs, which would be a moment that would change history.

Zhu Shou touched his beard, looked at Li Qing busy there with a puzzled expression, and said to Li Chunyang beside him: "Old Taoist, you said that this saltpeter can be used to ignite the fire, I know, what is the way of sulfur?" ”

Li Chunyang frowned and shook his head, as a disciple of the Dao Sect, Li Chunyang was often in contact with all kinds of ores, but he had never thought about what kind of power these seemingly ordinary things could burst out through some clever combinations.

Li Qing crushed the sulfur and saltpeter, and then had the people burn some charcoal, which was also crushed into powder.

Everything was ready, Li Qing mixed saltpeter powder, sulfur powder and charcoal powder together according to the proportion, in fact, at this point, Li Qing's gunpowder was already successful, but Li Qing's purpose was not so simple, he not only wanted to make gunpowder, but also to make explosives.

Although there is only one word difference between gunpowder and explosives, in terms of power, it is very different, and the method of making explosives is actually not much different from gunpowder.

Looking at the "explosives bag" wrapped in coarse cloth in his hand, a trace of flush flashed on Li Qing's face, which would be a moment that changed history.

Fan Cheng and the others looked at Li Qing blankly, not understanding why Li Qing was so excited, and Li Qing didn't know how to explain it, so he decided to try the power of this explosive first.

Let everyone dig a deep pit first, and then Li Qing's "explosives bag" was put into the pit, leaving only a long fuse outside.

Li Qing waved his hand at everyone and asked them to step back, Li Qing didn't dare to guarantee the power of the "explosive pack" made by this one, so for the sake of safety, Li Qing still decided to let everyone retreat as far away as possible.

Seeing that everyone was about to retreat, Li Qing took out the fire fold, lit a torch, looked at the swaying flames on the torch, Li Qing swallowed his saliva, carefully lit the fuse, and then immediately ran away.

……

There was silence, the explosion in Li Qing's imagination did not happen, Li Qing looked at everyone's puzzled expressions, and couldn't help but show an embarrassed look on his face.
