In fact, many times people and things are just separated by a layer of window paper. For example, the one who was smashed with the apple. Another example is the one who smashed the durian. The former became a scientist. The latter created a popular cross talk joke for the people.

Now Guan Zheng has pierced the layer of window paper between him and the gunpowder. What can he leave for the world? Unknown. But since the day of the hit. There will be a "boom" sound every once in a while. It's like thunder on a dry day. The clear sky is like a thunderbolt.

The people don't know what the mysterious Momen is up to. The obvious is . There have been more bald heads in and out of the ink gate lately. Some people thought, "Could it be that the people in Momen want to become monks. Or is it. Momen is going to change course and turn into a temple."

The ink gate is still the ink gate. The children of Momen are still the children of Momen. Momen did not become a monastery. The Momen disciples did not become monks. Day. Still living so calmly. Until one day......

"Positive. square." Guan Zheng, who had just finished his morning class with Huang Li'er. I just got up and put on my pants. There was a knock on the door from Huang Chengyan.

"What is the value of old Tarzan?" The door was opened a little crack. Half of his face and one eye are exposed. Guan Zheng said to Huang Chengyan very politely.

"You kid ......" Huang Chengyan as a passer-by. How could he not know that the hairy son-in-law was playing a game of goblin fight with his daughter in the house. Pointing to Guan Zheng's nose and speaking. Tilt your head. Motioned to the old man to get dressed and go out to talk.

"Tarzan. It's early in the morning." Guan Zheng is neatly dressed. Yawned and walked behind Huang Chengyan, who was standing in the center of the small courtyard.

"Look. It's done." Huang Chengyan's eyes flashed with a strange light. Spread your palms out of the way.

A metal arrow. There's a little stick on the back of it. Just lying horizontally in the palm of Huang Chengyan's hand. It reflects the cold light in the light of the morning sun.

"This is ......" Guan Zheng took the metal arrow in his hand. I flipped left and right. I really can't guess what this thing is.

"Come and see." Huang Chengyan thrust the arrow with the small stick on the ground. Pull a little tail out of the arrow. Take the fire sickle and sneer a few times to set the little tail on fire.

"Whew......" for a long time. The little tail burned to the end. The arrow chirped. Straight to the sky.

"Monkeys." Guan Zheng raised his head and looked up at the sky along the green smoke left behind the arrow's buttocks. Mouth screamed.

"Monkeys. The virtuous son-in-law knows this." Huang Chengyan hurriedly stepped forward. Grabbing Guan Zheng's cuffs, he asked.

"Hey. I'll tell you. In the long future, this thing will be on every stall that sells firecrackers?" Guan Zheng looked up and recalled his childhood. muttered to himself.

"Oh. Where will the son-in-law know about this thing? It's just amazing that there is such a ingenious thing." Guan Zheng hurriedly covered it up when he heard this. He didn't dare to say it. This thing rotted on the street after 1800. That's it. He's going to be insane.

"The old man's door. Day and night development. And only to this extent. I can be sure that there will be no accidents." Huang Chengyan picked up the falling metal arrow from the ground. Said in a deep voice. In order to develop this so-called **.Momen disciples, several people have been injured by the explosion. R&D belongs to R&D. But at the cost of life. Huang Chengyan felt that it was still a little difficult to accept in his heart.

Seeing that Huang Chengyan seemed to be a little dissatisfied with the power of this Sky Monkey. Guan Zheng stepped forward and said, "Uncle Yue, don't underestimate this thing. One or two may not see its power. But if it's tens of thousands."

"Thousands of ......" Huang Chengyan seemed to be behind a cloud of green smoke in front of him. The monkeys are overwhelmingly rushing towards the enemy.

"So. Uncle Yue made as many monkeys as he could. Maybe one day the son-in-law will still rely on this siege, and it may not be." Guan Zheng took the arrow that flashed with cold light from Huang Chengyan's hand. Rubbing said.

"That's no problem. As long as the materials are sufficient. The old man can let those little cubs make a steady stream of them." For the process of manufacturing the Monkey Channel. Huang Chengyan is already a bamboo in his chest.

"Father-in-law. You don't find out. The Monkey can be transformed into silver." Guan Zheng touched his chin. reminded Huang Chengyan of a sentence.

"Uncle Yue can use paper instead of this metal arrowhead. Then go out and sell it during the New Year's holidays. Jiangdong and the whole world. One person buys you a monkey. How much can you make old?" Guan Zheng remembered the firecrackers of later generations.

"You really don't know how expensive firewood and rice are. You think it's cheaper to use paper. Bastard boy." Huang Chengyan knocked on Guan Zheng and said with a chestnut.

"Uhhh Guan Zheng then remembered. Paper seems to be more expensive than metal in this era.

"That can be replaced with wood or bamboo. That's no problem. Just add some gunpowder to it." Guan Zheng instantly came up with another idea.

"This can be there." Huang Chengyan pondered for a long time. Nodding yes.

After the two made up their minds. Guan Zheng paid some silver in advance. In the territory of Koto, the materials used to make the monkeys were purchased on a large scale. The people woke up. Suddenly I found those finger-thick rotten bamboos. I can also sell it for a penny.

And those Taoist priests who make a living from alchemy. It is the saltpeter in the hand. Charcoal. Sulfur and other substances. All of them were packaged and sold to merchants who came to buy the materials. In their opinion. I don't need to suffer in front of the alchemy furnace anymore. You only need to refine these materials to ensure that you have no worries about food and clothing.

Guan Zheng came up with this idea. Inadvertently, it has greatly boosted the gDP of Jiangdong.

"You have the idea. It works. In case my dad did a lot. What if you can't sell a single one?" After explaining some precautions to Huang Chengyan. Guan Zheng decided to return with Huang Yueying. On the way back. Huang Li'er said obviously with some unease.

"In case none of them sell. It's good that your family is round. Rest assured. When the time comes, it will definitely be in short supply." Master Guan confidently assured his daughter-in-law.

"That's pretty much it. I can tell you. Don't let my dad bring the coffin book in. Otherwise. Next time, don't think they'll put on that embarrassing pose." Huang Yueying is very satisfied with Guan Zheng's attitude. But in the end, he was still there to warn him with a certain Guan Zheng's favorite sport.

"Where there is a penalty, there is a reward. If the father-in-law makes a lot of money." Guan Zheng took the opportunity to beat the snake and brought up the conditions on the stick.

"Whatever you want." Huang Yueying glanced at this thing with a charming face. A pursed mouth and said shyly.
