The side room on the second floor of the main house in the small courtyard was used by Lin Liangyou to pile up sundries.

Although Yu Miaolan went back to live in the teaching workshop, the room in the middle was restored and retained, in case another guest came to live one day, it would save moving around.

The case of the Teaching Workshop Division is really settled. Jin Chang, who forced Huang Ze's aunt to death, and Huang Ze rebelled against the party, and Ji Du commanded the envoy to send someone to get it, so they didn't have to worry about it.

I can finally breathe a sigh of relief, take a good rest, and enjoy the little rest left in the year.

The only thing that can't be done now is to help Yue Rong find her own brother.

Hey, don't you ...... No, I can't find it!

Fortunately, Yue Rong didn't urge him for the time being, Lin Liangyou suspected that this little girl would sneak out in the middle of the night from time to time, he was too tired for the past two days, and slept with a pillow, so he didn't hear any movement.

Today, I finally eased up, but I couldn't be idle, so I first went to the Gunpowder Division of the Inner Court Warfare Bureau, and "asked" a little thing from my father-in-law on duty, and rushed into the second floor after coming back......

Zhang Ben's injury was almost recovered, and he slept until the afternoon, got up and ate the lunch that Lin Liangyou left for him, and watched Yue Rong and Lin Long tease the cat in the courtyard to bask in the sun, the gentle sunlight in late winter and early spring sprinkled on their pink cheeks and black hair, and the years were quiet.

There is no sign of Lin Liangyou.

"Little sister, where is your brother?" Zhang Ben asked.

Lin Long is still very simple, and said honestly: "Brother Zhang, my brother is upstairs!" ”

The clothes drying on the bamboo poles swayed gently with the breeze, which were all hand-washed by Yuerong Lin Long and the two of them, since the "washing machine" was shaken by Zhang Ben, there has been no time to repair it, perhaps, I don't want to repair it at all.

Zhang Ben thought that Lin Liangyou was repairing the "washing machine" upstairs, and looked upstairs, but saw that smoke was billowing out of the room on the left, and he shouted "nest" in his heart, and hurriedly ran upstairs!

As soon as I went upstairs, I saw that Lin Liangyou had already run out of the room, his face was scorched, and he was lying on the railing and coughing in the wind.

"Second brother, what are you doing!" Zhang Ben shouted, "You won't really change the washing machine into a barbecue, will you?" ”

"Ahem—" Lin Yanyou wiped away a handful of smoked tears.

"Brother, are you alright?" Lin Long craned his neck and shouted. She and Yue Rong also saw the smoke.

"I didn't ...... It's okay. Lin Yanyou waved his hand downstairs, rushed into the room, lifted the linoleum cloth that covered the ground with faint smoke and looked at it, then closed it again, turned his back to Zhang Ben and said, "There is no smoke, big brother, come in and say!" ”

Zhang Ben hesitated, and saw that a piece of bamboo was hung next to the door of the small room, with the words "Wenxi Pavilion" written on it.

"You kid, you're getting serious!" He couldn't laugh or cry.

Lin Liangyou squatted on the ground with his back to him and was drumming about something, seriously engaged, and when he heard Zhang Ben coming in behind him, he didn't even look back.

"What are you doing?" Zhang Ben asked, "What does the invention cost you three thousand?" ”

"Big brother, you came just in time......" Lin Lanyou wiped his face, stood up and turned around, and did not wipe the smoky blackness on his face.

"If I hadn't seen this smoke, I would have thought you had caught a cat in the hearth!" Zhang Ben said.

"Big brother, I recently discovered that charcoal, saltpeter, sulfur ...... Placed in a small space......"

"For example, in the mouth of a man, right?" Zhang Ben stretched out his hand and slapped away Lin Yanyou's palm that was stretched out under his nose angrily, and knocked all kinds of powder from his palm to the ground, "Boss! Can you be sober, you won't know that our Ming firearms, not to mention crushing the world, are also second to none! Hongwu iron cannon, handcuff bowl mouth gun, three-eyed gun...... With so many cannons, do you still need to put gunpowder in your mouth? ”

"Yes, I know, but there's one thing missing."

"What?" Zhang Ben jumped back a step, "You don't want to borrow my mouth to try it, do you?" ”

"Smoke bombs!"

"Smoke-fog-bomb?" Zhang Ben frowned, gritted his teeth, and repeated word by word.

"Now that the materials are ready and the smoke can be emitted, the only problem that hasn't been solved is ......" Lin Liangyou squatted down and fiddled again.

Zhang Ben also squatted down and looked at the boxes on the ground: "Black powder, lime, sucrose...... You went to the Gunpowder Division to make these things? Isn't it possible to buy the old craftsman Li who makes fireworks in the west of the city? ”

Lin Liangyou smiled evilly: "Of course not, these things are purely hand-to-hand." I went there and observed the imitation Song iron-shelled mine, mainly to study its triggering method for reference, but unfortunately, it is a traditional medicine line ignition ......"

"What, isn't it good to ignite the medicine line?"

"It's not that it's bad," Lin Yan lobbied, "it's just a smoke bomb that doesn't suit me!" ”

"You've eaten too much chicken, right? What kind of smoke bombs, didn't you say you don't do these things? Zhang Ben felt that the second brother was a little unreasonable, knowing that he hated the traverser for inventions, otherwise he wouldn't have beaten Xia Di badly!

"I'm just making small inventions and gadgets, just for my own convenience, and I won't hinder the progress of Daming. Besides, we really don't have the ability to make big inventions. Lin Liangyou knew the eldest brother's concerns and smiled, "Isn't it because of Jin Chang's thunder escape that night, which inspired me!" With smoke bombs, if we encounter a crisis situation in the future, we can get out with a bullet, how good you say! ”

"......" sounded, but it didn't seem to have any adverse effects on the people, Zhang Ben's mood eased a little, "Well, so now, what problem are you encountering?" ”

"I just want to make a hair pull, the kind that makes it smoke when you pull it." Lin Liang lobbied, "The ignition is too slow, and the smoke hasn't come out for a long time." ”

"So? I can't help you. ”

"I once saw in the literature that the emperor once built a Taihe Palace at the top of Wutian Pillar Peak. And in front of Emperor Zhenwu of Taihe Palace, there is an ever-bright lamp. "It is said that as soon as the door of the main hall is closed, the light will go out, and as soon as the door is opened, the light will be on again...... he said, he picked up a piece of bamboo tube on the ground: "If my bamboo tube is the main hall, the gunpowder and other things in it are the everlasting lamp, and the bamboo tube is sealed, which is the door of the main hall...... As soon as I pulled the seal, the lamp lit up, and the smoke billowed out in an instant! ”

"Hmm, so?"

"You've been to Wudang, do you know the principle of the ever-bright lantern?"

"Who told you I went to Wudang?"

Lin Yanyou patted his head: "I'm sorry, you have studied art with Daoist Qiu Xuanqing, I always have preconceived ideas......"

Zhang Ben said: "Although I have never been to Wudang, I also know the principle of the ever-bright lantern. ”

"Oh?" Lin Liangyou's eyes lit up.

"White phosphorus!" Zhang Ben said.

"Makes sense!" Lin Lanyou patted his head again, "Why didn't I think of it?" But where do we get white phosphorus? ”

"Aren't you there?"

Lin Liangyou looked at the flint in his hand......

The ancients have long discovered two kinds of flints, one is the one held by Lin Liangyou, which needs to be rubbed to ignite the fire;

There is also a layered flint in the water, which can spontaneously combust as long as it is exposed to the water and exposed to the air.

The difference between the two is just how much white phosphorus is exposed to the air, and those that are prone to spontaneous combustion are exposed to more white phosphorus.

So, the flint in his hand can also be used!

……

Lin Liangyou lowered his head and continued to concentrate on studying his smoke bomb, and Zhang Ben on the side shook his head and walked out of the room.

After a while, Zhang Ben ran into the room quickly and kicked Lin Yanyou's buttocks: "Second brother, don't do it!" This smoke bomb has already been made by others, and the smoke is much older than yours! ”

"Is there such a thing?" Lin Liangyou put down the work in his hand, followed Zhang Ben out of the house, and leaned on the railing on the second floor to look into the distance-

I saw smoke billowing from the gem mountain outside the city, as if wolf smoke had been released.

The smoke came from the Jianchu Temple on Jubao Mountain......
