At night, at the bedroom, Zhang Lihua woke up from a nightmare. In the dream, she transformed into the "Shitaxi" agent Lian Hongling. In the strange insect valley, she retreated to cover her boss Watson. She held a fire gun and a sharp blade in her hand, and dealt with a monster alone, and finally fell into the abyss.

In the abyss, countless huge black shadows were twisting, and seeing living things falling above, they shouted happily.

This dream was too real, which made her sweat in a cold sweat. When she opened her eyes, she found that she was lying on the couch. The story of "South Central Insect Valley" I watched today was so thrilling that it made her think about it day and night.

However, the sound of gasping was still coming from her ears. She turned her head and looked, and with the help of the faint lights penetrated from the window, she saw the shadows and the two around her entangled together, constantly moving.

After the clouds were gone, Zhang Lihua waited quietly for a while, then stood up, picked up the thin quilt that had slipped down, covered the two of them, and then whispered:

"Erlang, I'm going to bring the water."

Yuwen Wen, who was facing her back, said "um". Zhang Lihua reached out to touch the small table next to the couch, touched a cardboard box, and then sat next to the couch wrapped in a thin quilt. In the dim light, she opened the cardboard box and took out a "light-seeking slave" from it.

"Yinguang Nu" is actually a thin wooden stem, shaped like a toothpick, with a "medicine ray" wrapped at the top. Zhang Lihua pinched the end of the "Yinguang Nu" and coated the head of the medicine ray on the side of the paper box. After a "click", nothing happened.

After a few more strokes, a ball of fire suddenly bloomed at the top of the "Light-Surprise Slave", and then started to burn, illuminating Zhang Lihua's face.

The beauty with the same face carefully held the "light slave" and leaned her against the candlestick on the small table beside the couch, lit the candle.

With the help of candlelight, Zhang Lihua saw the scene beside her couch, picked up the nightgown that she had put on, loosened the thin quilt wrapped around her body, and put it on to avoid catching a cold while going to get water naked.

The "air conditioner" was turned on in the bedroom, and the temperature was slightly cool. Zhang Lihua went to the outside room to bring warm water. When she returned to the couch, she saw Yuwen Wen sitting next to the couch, staring at the candlelight in a daze.

Chen Wu, whose blush had not yet subsided, lay softly on the couch, his eyes blurred, as if he had lost consciousness. Zhang Lihua quickly stepped forward and draped the quilt on Yuwen Wen: "Erlang, don't catch a cold."

"Yeah." Yu Wen Wen finished drinking the water, looked at the candle, then looked at the "Yinguang Slave" next to the candlestick, and asked, "You just took a few strokes before igniting it?"

"I remember it seems like I'm going around."

“From….”

Yuwen thought to himself when he heard this, opened the paper box, took out a "light spider" and scratched it on the side of the paper box.

Just in a moment, a fire burst out from the top of the "Spiritual Slave", and then it began to burn. Yuwen Wen stared at the jumping flame until it was about to burn to the end and then opened his mouth to blow it out.

The ignition success rate is frequent and the quality seems to be unstable...

Yuwen Wen thought so, hugged Zhang Lihua and lay down, but did not blow out the candle, but instead started talking to the person in his arms.

"The sales of this match feels unsatisfactory. What's the reason for what you see?"

"Erlang, this light is good... this match is good, but it is a bit embarrassing. It is not affordable for ordinary people and does not need it. But those who can afford it can actually use a fire sickle..."

The two of them started discussing, and Chen Wu, who slowly came to his senses, became interested as he listened.

The light-sucking slave is a kind of fire-sucking object, made of thin wood strips dyed with sulfur. When Chen Wu was a child, he often saw people using the light-sucking slave to attract fire when he was working in the palace with his mother.

But the light-sucking slave himself does not burn, so he needs to ignite it with open flames and then use it as a small torch to ignite other flammable objects.

This is the Yin Guangnu that Chen Wu knew. Now, there is a new style of Yin Guangnu, called "Match".

The match is said to be wrapped in a "medicine guide" with sulfur as the main component at the front end, while the paper box containing the match is thin wood chips on the side wall and a layer of medicine is covered with the outside. It is said that glass powder is mixed in it to "friction and heat generation".

When using the match, you pinch the end of the match with your fingers and then coat the match head on the side wall of the paper box. Because "friction generates heat" makes the coating and the match head "friction generates fire", the match itself burns without additional open flames.

This kind of "friction creates fire" may not be successful if you mark it once, so you need to mark it a few more times.

Sometimes I have bad luck, and even a match is cut to the top and the medicine is gone, and I cannot successfully ignite the fire, so I need to take out another one to scratch.

Chen Wu has experience in using this, so she feels that since the ignition rate of matches is erratic, it is better to use a fire sickle. After all, the price of a fire sickle is lower than a box of matches, and there is no risk of a fire.

Matches are not safe, and a box of matches is placed in your pocket. When people walk around, the matches may burn themselves, which means spontaneous combustion.

Chen Wu didn't know the reason why the match was spontaneously ignited. If she was asked to choose a fire-burning object to take it out, she would rather choose a fire sickle than a match that would spontaneously ignite.

This new "light spouse" was officially sold not long ago. For Chen Wu, she doesn't need to pay attention to how to cause trouble, because there are naturally maids who are busy with this kind of thing, so there is no need to know how its sales are.

Now that I heard the two people around me discussing, it seems that Match's sales prospects are bleak.

It’s dim, so how much money can you make by selling such a gadget?

"This is not a question of how much money can you make." Yuwen Wen responded to Zhang Lihua's questions. Of course, he didn't know what Chen Wu was thinking around him.

"Fire is very important. Cooking rice, driving away the cold, and baking clothes requires fire. It is very important to make a fire easily and quickly without open fire."

"The matches are not perfect and the ignition rate is unstable. It doesn't matter. Then continue to improve. The price is too high. It's better to use a squirrel. Then find ways to improve the manufacturing process and reduce costs..."

"But you are right." Yuwen Wen hugged Zhang Lihua hard, "Matches are not necessary for civilians, and they will not spend this in vain to buy them..."

"For a wealthy family, the man-in-law does not need to care about how to ignite the fire. Then the servants responsible for ignition are not qualified to require high-priced matches, but do not need cheap squirrels."

"In this way, if you want to promote matches, you must create a strong demand for them, that is..."

Speaking of this, Yuwen Wen sat up and sighed a little.

When he didn't have a lighter, he felt that one of the biggest uses of matches was to light a cigarette. Otherwise, if smokers wanted to light a cigarette gracefully, they would not squat in the corner and ignite with a scythe.

However, tobacco is native to America, and there is no tobacco in the Central Plains now.

Without tobacco, there will naturally be no cigarettes, so rich people basically don’t need to carry them (or their servants) to light matches.

Without the old smoke gun, how can you sell matches?

As he thought about it, Yuwen Wen's thinking diverged:

Tobacco, chili peppers, cinchona for malaria, corn, potatoes, etc., these good things are all in the Americas, but they are still far from "discovering" America. So should we organize a fleet to fight eastward and start a "great route"?

"Erlang, be careful not to catch a cold."

Zhang Lihua's reminder made Yuwen come to his senses. He wanted to lie down, but saw marks on his index finger. It was probably left when he was scratching a match. He shook his finger in front of Zhang Lihua: "Get a piece of paper."

Zhang Lihua slept outside, with a "namon paper" on the small table beside the couch. Yuwen Wen meant that Zhang Lihua would use paper to wipe his hands. Unexpectedly, the beauty sat up behind her and opened her mouth and held his finger in her mouth.

Then suck.

This made Yu Wenwen feel as if he was electrocuted and his whole body became energetic. The "fire" that had already been extinguished was instantly ignited by the "light-sucking slave" Zhang Lihua.
