After a while, Little Green Dress pulled out a pile of charcoal powder. Zhang Zheng picked up a little bit and rubbed it on his fingertips, it was very good, very delicate.

Then he said to the little green dress: "Okay, that's enough, go get me two eggs, find a sieve, and take a few sections of the bamboo used to burn firecrackers in the house." As soon as Xiao Lushang heard that Zhang Zheng had enough, she immediately stopped what she was doing.

Then he rubbed it his face, and his face became darker. Zhang Zheng held back a smile, but he didn't plan to remind Xiao Lusheng that it was also a joy of life to occasionally watch the maid be ugly.

"Yes, slave and maid will go." Little Green Dress jumped up and down to get what Zhang Zheng needed. Zhang Zheng weighed several kinds of ground powder on a small scale.

Again and again, he muttered: "What is the golden ratio, well, it probably seems to be 721, well, it should be right." After muttering, Zhang Zheng weighed out a pile of saltpeter powder for later use, and began to weigh charcoal, and finally sulfur powder.

Then three small piles of powder were mixed together, and a small pestle was stirred evenly, and a pile of gray-black powder appeared in front of Zhang Zheng's eyes.

It just so happened that Xiao Lushang also found what Zhang Zheng wanted. Zhang Zheng took an egg from Lusheng, beat some egg whites into the powder, and then used a sieve to sift the powder into grains the size of rice grains.

Zhang Zheng saw a pile of gray-black particles the size of a grain of rice placed in front of him, a smile appeared on his face, and then he reached out and clenched his fist.

A picture of Zhizhu holding it said to the little green dress whose face was blackened: "Finish the work!" The green dress bent over with her hands behind her back and stared at the pile of particles with a curious expression, and a pair of big dark eyes rolled around her dark face.

After watching it for a long time, I couldn't connect the mixture of granular pin charcoal and sulfur with egg liquid, and the cannon that could make a loud noise in Zhang Zheng's mouth.

I couldn't help but ask curiously: "Xiaolang, this is what you said about the cannonball, can this sound?" Zhang Zheng smiled mysteriously at the green dress and sold it: "This is not a finished product yet, you will know if it can ring for a while." Then he picked up the sieve and went into a room with floor heating and opened the window.

Place a small sieve in the room to dry the water from the underfloor heating. He went outside again, took a knife, and began to trim the dry bamboo joints, and made the bamboo joints neatly into small sections one by one.

Xiao Lushang watched curiously as Zhang Zheng carried out a series of inexplicable operations, and her big black eyes were full of doubts.

After Zhang Zheng cut off the bamboo, he saw that Xiao Lushang was still watching, so he pulled her to the big rain urn under the eaves to catch the rain, and then pointed to her face with a wicked smile.

Green Dress touched her face and looked at Yu Weng curiously, and a black face was reflected in the water.

Xiao Lushang was taken aback, and then reacted that she was teased by Zhang Zheng again. exclaimed: "Ah, Xiao Langjun is a bad person." So he covered his face and ran away without looking back.

Zhang Zheng smiled and continued to tinker with his own things. The cotton paper was covered with the remaining gray-black powder, and the powdered cotton paper was rolled into thin strips, which was the lead.

After a while, the particles in the room were dried by the temperature of the floor heating, and Zhang Zheng evenly packed the particles into the cut bamboo joints.

After inserting the lead, seal it with a little red clay, leaving a half-foot-long lead on the outside.

In the blink of an eye, twenty or thirty enlarged versions of firecrackers appeared on the table in front of Zhang Zheng. I saw that there were still many particles left in the sieve, and the bamboo joints that I had cut out had been used up.

Zhang Zheng thought about it, found two small clay pots, and made two cannon battles like grenades. Weighing the weight in his hand, Zhang Zheng smiled evilly and said to himself: "Well, these two will be sent to Li Er later." After saying that, he seemed to think of something particularly funny, and couldn't help but hold his stomach and laugh.

After laughing for a while, Zhang Zheng began to look forward to it. I don't know what Li Er's expression will be after seeing the power of the cannon battle.

It's no wonder that Zhang Zheng has such a bad taste in his heart, it is true that Li Er turned his face faster than he turned a book, which made Zhang Zheng hold back his dissatisfaction.

And with this thing in his hand, he can not only give it to Li Er justifiably, but also take this opportunity to take a small revenge.

It's also funny to think of Li Shimin's frightened pale face. When Xiao Luyi changed his clothes and came to Zhang Zheng's courtyard, Zhang Zheng's expression had already recovered as before.

Seeing the little green dress jumping into the yard with his hands behind his back, the corners of Zhang Zheng's mouth turned up slightly, and he said to the little green dress a little evilly: "Go, the son will take you to set off the cannon." Hearing this, Xiao Lushang wrinkled her nose, and when she saw that kind of evil smile on Zhang Zheng's face again, she immediately rolled her eyes and glared at Zhang Zheng: "Hmph, people don't go, Xiaolang is a bad person." ”

"Oh! If you don't go, forget it. Zhang Zheng shrugged, replied indifferently, and then stopped all the firecrackers on the table into his arms, raised his feet and walked to the front yard.

didn't even look at the green dress, only left a chic back for the little green dress. It's just that what Little Green Dress doesn't know is that Zhang Zheng's face with his back to her is still the same evil smile, and he still counts in his mouth: "One, two, three!" Sure enough, seeing Zhang Zheng turn around and leave, Xiao Lusheng's face suddenly felt a little annoyed and entangled, but in the end, curiosity prevailed.

When Zhang Zheng counted to three, he couldn't help but stomp his feet, then lifted his skirt and chased after Zhang Zheng's back, shouting: "Xiaolang, wait for the slave." ”

"Hahaha......" Zhang Zheng laughed, it was really a very interesting thing to tease the little green dress when he was bored.

Green clothes quickly caught up with Zhang Zheng's footsteps, and followed Zhang Zheng like a little daughter-in-law.

The expression on the little face was puffed up, and he secretly hated himself for being too uncompetitive. Zhang Zheng swept away with his peripheral vision, and the little green dress changed into a light green bandeau, and his already developed bumpy figure was covered by a wide skirt.

The cheeks bulged, and the long eyelashes trembled and trembled, and he kept pouting because he was angry, and he couldn't say how cute he was.

Zhang Zheng smiled secretly in his heart, little look, the son can't cure you. The master and servant walked to the front yard and were about to go out, when Li Wucun and Qiu Shisan, the two rivals, appeared from nowhere.

And the two were followed by Chen Yu with a helpless face. Seeing that Zhang Zheng was about to go out, Qiu Shisan hurriedly waved at Zhang Zheng and shouted, "Where is Shaolangjun going, wait for me!" Then he trotted all the way to Zhang Zheng.

Zhang Zheng looked fixedly, and Chen Yu, who noticed Zhang Zheng's gaze, couldn't help but spread his hands and made a helpless movement.

Zhang Zheng couldn't help but have a headache, he took his sister to set off the cannon, and suddenly three big men appeared What's the matter.
