When night fell, the guys in the fireworks workshop had already left work, and the three of them quietly touched the hut, and the oil lamp inside was always on, but no one was visible.

Qin Fan walked into the thatched hut and saw all kinds of fireworks drawings on the table, these drawings were cleverly designed and accurately composed, not like ordinary people could easily make them.

"Look closely, is there anything suspicious?" Qin Fan reminded.

The crowd rummaged through the hut for a long time, but did not find any possible mechanism or secret passage, and just as they were about to leave, there was a sudden creak, and the long table was split in two. Two four-square-meter planks on the central floor sink and then split off to the sides under mechanical drive, casting a dim light through a narrow and rudimentary dark tunnel.

There was a sound of footsteps in the dark passage, and Qin Fan, who was about to go down to check, hurriedly retreated, and the three of them hurriedly found a corner to hide.

A young man in red quickly came out of the ladder in the dark passage, but what made people laugh was that the young man's clothes were burned through many holes, his face was full of smoke, his face was gray, and his hair seemed to be smoked like an explosion.

"It's really hateful, and it failed again...... What is the reason? ”

The young man muttered as he walked with a depressed expression, and when he reached the hut, he stepped on a small plank on the floor, and the floor began to close again.

Qin Fan looked at him and lowered his head and muttered for a long time, and when he was at a loss, the young man in red suddenly raised his voice and said, "Come out, a few friends, your skills are too poor." ”

Qin Fan: ......

Qin Fan saw that the other party had already noticed that he was waiting for the others, so he had to stand up.

"Who are you? What are you doing in the middle of the night breaking into my hut?! ”

The young man didn't seem to be worried that Qin Fan would be unfavorable to him, and said as he sorted out the drawings.

Qin Fan thought for a while and said, "The golden dragon spits fire and flies, and the silver snake treads water and is shocked. Fenglai Nine Heavens Thunder Rolling, Thousands of Horses and Thousands of Troops Are Hard to Return! If you ask who opens the heavens, Qinhuai Yanyun Lu Eagle Eagle! ”

"How do you know this poem?!"

Sure enough, as soon as Qin Fan read out this poem, the young man's face was suddenly full of surprise, and the young man said in surprise: "This poem was written when I was young, and it is hidden in a special scroll...... Did you get that scroll? ”

Qin Fan nodded: "I got information about you from the scroll, so I came from thousands of miles away, hoping to see the picture as mentioned in the poem, and also hoping to get help from someone like you who has real talent and learning." ”

Qin Fan didn't need to confirm it anymore, he was very sure that the person in front of him was Lu Diaoying.

"This poem was written when I was young and ignorant, so that someone might learn what I had learned. In the blink of an eye, ten years have passed, and I thought that I would not have a chance in this life, and I didn't expect that the opportunity would be such a coincidence. ”

He turned around and said to Qin Fan, "That's right, I'm Lu Diaoying!" ”

"Brother Lu, can you explain the meaning of the first four lines of this poem?" Qin Fan didn't know what kind of profession this Lu Eagle had until now.

"Come with me......"

Lu Diaoying did not plan to wash his face and change his clothes, but reopened the secret door of the tunnel, and Qin Fan and the three of them followed Lu Diaoying through the ten-meter-long secret passage and stepped into a basement room about more than 100 square meters wide and one zhang high.

The ceiling of this basement is made of countless bamboo ventilation holes to bring in air from the ground, so that even though there are several oil lamps, you can breathe freely.

In the center of this basement were several tables, each filled with a mess of things, and against the corner of the wall were a dozen wooden barrels, which contained a black-gray powdery substance, like ...... Gunpowder!

Qin Fan subconsciously took a few steps back, Lu Diaoying went straight to a table, handed Qin Fan a special feather arrow with a thumb-thick and inch-long paper tube at the end, and said, "This is the thing described in the poem. ”

"! Rocket! ”

When Qin Fan saw this thing, he immediately blurted out, this thing is simply an enlarged version of the Sky Monkey! The paper tube carried a cotton wick soaked in oil and wrapped in gunpowder, and Qin Fan didn't know how much he had played with it when he was a child.

"How do you know its name?!" Lu Diaoying was very surprised, and then said: "This is the Thunder Rocket that I first made ten years ago to expand the lethality of feather arrows, this paper tube is filled with black powder that is more explosive than fireworks gunpowder, and I also loaded a large number of iron filings and iron balls in the front of the paper tube. After the lightning rocket ignites the fuse, it uses a longbow to shoot out, and when it is ignited at the bottom of the powder keg in the air, it can accelerate the speed and strength of the feather arrow, making it fly farther, up to 500 meters. When the Thunderbolt hits or falls near the enemy, in addition to the lethality brought by the arrow itself, the cartridge will also explode at the same time, sending iron filings and iron balls flying at high speed, killing enemies within at least three meters around the target, even if the enemy is wearing armor, it is difficult to prevent! ”

Cow Pie!

Qin Fan secretly admired, this is simply black technology in the ancient battlefield, and the energy of this Lu Diao Eagle is by no means ordinary.

Lu Diaoying looked at the adoring eyes of the three of them, the satisfaction in his heart was overflowing, and he continued to lead Qin Fan to another table, on which was placed a wooden barrel with a diameter of two inches and the same length as the Fang Benlei rocket, and the barrel had fifty round holes in cross-section, like the launch box of a fireworks cannon.

"This is an upgrade to the Benlei Rocket, I call it a swarm! I took into account that the sergeant shot the Benlei rocket alone, which was troublesome to operate and could not suppress the enemy in a short time, so I increased the amount of Benlei rockets, and then tied them together and made this swarm of bees, as long as one fuse was ignited, fifty Benlei rockets could be fired at the same time, with a maximum range of up to 30 meters, and the effect was most significant in the enemy's dense formation! I'm going to assemble this swarm of ten boxes in one on my special rocket car, so that it will be easier to transport and use. ”

Then he took out another oversized monkey made of bamboo tubes, with a dragon head carved at the end, and the thickness of a calf. Four large gunpowder canisters were tied to each of the bamboo tubes, and there were also jet vents at the bottom of the main body.

"This is a new weapon I'm working on: the Fire Dragon Out of the Water!" Lu Diaoying said proudly: "Although this fire dragon looks rough out of the water...... Large, but with the thrust of four jet canisters, it can rise directly into the air and fly to the target. When the four powder cartridges are burned out, the gunpowder at the bottom of the main tube will ignite, continuing to drive the fire dragon to fly, and when it approaches the target, a large number of iron balls and iron filings will be detonated to kill enemies within a radius of five meters! ”

"Even drop god, second-stage rocket!" Qin Fan looked at Lu Diaoying in shock and said slowly: "Brother, are you sure that you are an NPC and not a big guy who has crossed into the game?" ”

"Crossing? Crossing what? Lu Diaoying said strangely.
