The other two were surprised. They didn't understand when Wu Zetian had such a good temper.

In their impression, Wu Zetian always didn't listen to anyone's orders.

"Immortal, Wan'er doesn't need this lighter. Just leave it to your highness." Shangguan Wan'er smiled and said.

"Yue'er doesn't need this lighter at present, let alone reading." Li Lingyue volunteered.

Your highness can't offend. You can win favor by saying something good at this time.

Sure enough, Wu Zetian looked at them with appreciation and nodded slightly: "you two did a good job. I'll reward you back."

"Yes!"

Shangguan Waner and Li Lingyue didn't talk on the surface, but they were happy in their hearts.

Your Highness's reward is not ordinary.

"Don't argue. Although I have only one lighter, I still have matches." Jiang Yichu said and took out two boxes of matches.

Looking at this strange thing, Shangguan Waner wondered, "immortal, what is this? Why did Waner see it for the first time?"

"Yue'er is also the first time to see you. Is this also a lighter?" Li Lingyue frowned and thought for a while and asked.

"Where is it? Although it's not a lighter, it has almost the same function and can ignite." Jiang Yichu said.

"Can you light a fire?" Shangguan Waner said in surprise.

"Immortal, how to use this thing? Teach Yuer quickly." Li Lingyue hurriedly said.

Just now I said I didn't care. It's because your Highness has it in his hand. There's no way.

Now there are other things, naturally.

"Watch it, I won't teach much." Jiang Yichu said, took out a match and struck it gently on the box.

Whoosh.

The match burned out a spark and soon lit, and the smell of smoke filled the whole space.

"This? This is also amazing. You can light a fire with a stroke?" Shangguan Waner was stunned.

Even if I have seen the magic of lighters, I can't help but marvel at the moment.

"What's the principle? It's the first time for yue'er to see you." Li Lingyue also sighed.

"Immortal, which one is easy to use, lighter or match?" Wu Zetian hesitated and said.

"You can see this just by looking at it. It must be a lighter that works better." Jiang Yichu smiled.

"So it is. I understand." Wu Zetian chuckled and stopped talking.

"Immortal, can Wan'er try this match?" Shangguan Wan'er hesitated and said.

"Try, please try." Jiang Yichu handed out a box of matches.

Shangguan Waner took it in her hand, first looked at it, carefully opened the box and took out a red match.

The red match is much lighter than she thought.

"Immortal, what are you going to do next?" Shangguan Waner glanced at Jiang Yichu and asked.

"Didn't I teach you? Forgot so soon?" Jiang Yichu frowned and scolded.

"Well, I'm just afraid of doing something wrong. I asked for insurance." Shangguan Waner smiled awkwardly.

"Yes, I won't teach it for the second time anyway. I'll remind you twice at most," Jiang Yichu said.

"Yes." Shangguan Waner replied respectfully and gently.

Whoosh.

The match lit and went out quickly.

"This, this, immortal, what's going on? Why did it burn for less than a second?" Shangguan Waner was stunned and asked.

Li Lingyue was watching and didn't know what to say.

What Wan Wan did is as like as two peas, but why didn't he make a fire?

"Just order two more times? This match is like this. It's not as convenient as the lighter. You can light a fire every time. You need to order two more times." Jiang Yichu smiled.

"So it is." Shangguan Waner nodded her head suddenly and wiped it hard again.

Whoosh.

Still not lit.

Shangguan Waner was unwilling and continued to order twice.

Finally, a match burst out and soon caught fire.

"Immortal, I did it." Shangguan Waner took a look at the few matches in the matchbox and breathed out.

"Why are you still waiting? Hurry up, or the candle will go out later, okay?" Jiang Yichu urged, feeling extremely anxious.

"Yes." Shangguan Waner promised, hurriedly picked up a match and lit the candle.

The candle burst into flames and burst into a coquettish spark.

"Well done. It's Yuer you next." Jiang Yichu threw another box of matches at Li Lingyue.

After receiving it, Li Lingyue picked up the match and struck it heavily.

Just now, through watching, she also learned some tricks. According to speculation, it is likely that the strength is too light, so she can't light it.

So as soon as she came up, she increased her strength.

Sure enough, there was a whoosh.

The match was successfully lit and succeeded only once.

Shangguan Wan looked at it. "Princess your highness, you are so great. The match was a success."

"Yue'er did a good job. I didn't mistake you." Wu Zetian said with a smile.

"No, it's just a coincidence." Li Lingyue knew that the match had a time limit, so she didn't dare to be reckless and lit the candle quickly.

Poof.

After a slight sound, the candle was successfully lit.

"Well done. Now you can take it back to your room carefully." Jiang Yichu nodded and said.

"Immortal, this candle seems to be holding something low?" Shangguan Waner suddenly pointed.

Jiang Yichu turned his head and saw that the candle was low with white things, sticky.

"Oh, that's normal. After burning, the candle will lower things like that. Just wrap it with this paper." Jiang Yichu glanced at it and said indifferently.

"It's so dangerous. That thing doesn't look good." Shangguan Waner shivered all over her body.

"Yes, immortal, is there any other way?" Li Lingyue asked.

"No, but although this thing looks scary, it's not dangerous at all." seeing them like this, Jiang Yi explained.

"What immortal said is true?" Shangguan Waner asked suspiciously.

"Really, as long as you don't take the initiative to touch it, I guarantee you have nothing." Jiang Yichu turned his eyes and said.

"Well, Wan'er understood. Thanks to the immortal today." Shangguan Wan'er breathed a sigh of relief, thanked and left with a candle.

Li Lingyue looked up at Jiang Yichu with a reddish cheek: "yue'er, thank the immortal today."

After saying this, he also took up the candle and left.

In the whole room, only Wu Zetian and Jiang Yichu were left.

"Immortal, are there any other books? I'm afraid one book won't be enough to read at night." Wu Zetian asked expectantly.

"There are other books, but you can't finish reading this book overnight." Jiang Yichu said instead of handing Wu Zetian other books.

"Oh? Why did the immortal say that?" Wu Zetian thought for a long time and said she was puzzled.

"The theory of monarchy is much more complicated than you think." he said mysteriously, and Jiang Yichu waved off the guests.

Walking on the road, Wu Zetian looked at the theory of monarchy from time to time, and remembered what the immortal said in her mind.

The monarchy theory is much more complicated than you think.

"Is it difficult that this book is actually an immortal book?" with such an excited mood, Wu Zetian returned to the room.

The next day, Jiang Yichu opened the door and woke up to find silence outside.

"What's the matter? What time is it? There's no one yet?"

Just then, Li Lingyue came over with two panda eyes: "good morning, immortal."

"I'll go. What did you do the other night? What's wrong with your eyes?" Jiang Yichu rubbed his eyes and thought he was wrong.

When he realized that he was right, he was surprised.

"Well, it's all strange. The candles are so easy to use. Yue'er is addicted to the middle of the night. She's a little excited and doesn't sleep. It's like this when she gets up this morning." Li Lingyue said bitterly.

"As for it? It's just a candle." Jiang Yichu shook his head.

But then a bold guess came to his mind.

"Xiaotian and Xiaoshang, can't something happen?"

With curiosity, Jiang Yichu came to Wu Zetian's door and knocked hard.

Bang.

There was a heavy noise, but there was no movement in it.

Li Lingyue was anxious: "immortal, what's going on, your highness, she......"

"Don't worry, wait a minute." Jiang Yichu knocked on the door again.

But there was still no movement inside, just like a pool.
