Ling Xia led the soldiers and horses through the hundreds of miles of secret passage, and directly came to the barren hill in Huanyu Province, at this time the other end of the secret passage was still in a sealed state, this is Ling Xia's previous retreat to cover, after Yingtian led his troops into Huanyu Province, he once sent soldiers to inspect this place, but because Ling Xia covered up the entrance of the cave very cleverly, so this place avoided the inspection of the soldiers of the Purple Turban Army.

Sent someone to gently chisel the rock and soil at the entrance of the secret passage, seeing that it was daytime at this moment, Ling Xia ordered the soldiers to turn the direction of the horses and put the saddle on the back of the car, so that it was convenient for the soldiers to retreat, taking advantage of the gap between the soldiers to rest, Ling Xia asked Boss Luo to park the carriages with wooden boxes, and sent people to carry the three hundred large wooden boxes loaded on the carriage to the front.

Before coming here, Boss Luo and the others originally wanted to bring some large equipment, but Ling Xia refused to let them bring any equipment, but loaded more than 300 large wooden boxes into the carriage, these wooden boxes were brought by Ling Xia from Mohai Province, and no one knew what they contained? But looking at Ling Xia's cautious appearance when he treated these wooden boxes, everyone guessed that this should be a treasure.

Now that Ling Xia is finally going to put these wooden boxes to use, Boss Luo and the others are all curious to come over, wanting to know what is in the boxes? The box can hold 100 catties of items, a total of 300 mouths, after opening it, I found that it was not any gold and silver jewelry, nor was it hemp boiling, but some powders of different colors, including black silk, gray, and brown......

With everyone's puzzled expressions, Ling Xia began to mix these powders according to the proportion, and muttered as he configured him: "Nitric acid, sulfur, saltpeter, lead...... Made, in order to gather these materials, Lao Tzu dug dozens of mines, but he didn't expect these materials to be so scarce in this era, and he worked hard to collect them for so many years, and finally only collected such a few materials. ”

Time passed bit by bit, after Ling Xia handed over the way of proportioning materials to Luo Boss and the others, after a busy day, they finally finished configuring all the materials in those wooden boxes, only to see that the powder was prepared into small square packages, each package was almost more than twenty catties, and there was a slender fuse exposed at the edge, Ling Xia called this package a gunpowder bag.

At this time, the sky was already dark, and Ling Xia and the others recuperated for a while, until around the second hour, he ordered the entrance of the cave to be opened and let the soldiers quietly walk to the hill outside the cave to gather.

"This is about thirty miles away from the city gate, Yue Qianfeng led a thousand masters to change into the clothes of the Purple Turban Army, each holding a gunpowder bag, pretending to be the Purple Turban Army to infiltrate the military garrison of Yingtian, remember, your target is the treasury of the enemy's garrison, focusing on the material warehouse, armory, grain and grass warehouse, medicine warehouse, stables, chariots, and the fifty towers near the edge of the city wall.

Give you two hours to find the target and hide your whereabouts on the spot, after two hours, you set the gunpowder bag on fire, and then throw it to the location of the target, and you will retreat after doing this, remember, these gunpowder packs will explode at a distance after they are ignited, you must stay away so as not to hurt yourself, and after the explosion and fire, the Purple Turban Army will definitely make a mess in the garrison.

My soldiers and I will disperse and surround the Purple Turban Army's garrison after you leave, and once there is a riot inside, we will launch a surprise attack on the enemy camp, and you will find a way to get close to those Purple Turban Army generals, taking advantage of the gap in the confusion of the enemy army's garrison, and quietly take action to deal with those generals, in order to facilitate identification, you all have a white cloth strip wrapped around your arm. ”

After arranging these, Ling Xia asked Yue Qianfeng to lead people to show up, and then, Ling Xia gathered the generals in front of him, whispered to everyone, and then ordered the generals to lead the troops away.
