Gu Wanwan looked at the two good students in front of her who were full of curiosity, and nodded with great satisfaction.

A good young man in the new era must be full of curiosity about advanced science and technology.

"In that bowl of water, I specially instructed Aoba to add alum to it."

"Alum?" Gu Mu frowned slightly when he heard this, and Ning Changyuan was also a little puzzled.

Before agreeing on the plan, Gu Wanwan only told him in advance that when she proposed the method of dripping blood to recognize her relatives in the court, she asked Qingye to add some alum to the water.

In this way, she dared to guarantee that when the time came, her and Gu Mu's blood would definitely be able to melt together.

In order to convince Ning Changyuan, Gu Wanwan also deliberately asked Aoba to conduct experiments with Dark Eleven. Take a glass of ordinary water, and a glass of water with alum added in advance, and drop the water of Aoba and Dark Eleven into each of them.

After waiting for a while, you can see that the two drops of blood in the ordinary water have not changed at all, but the two drops of blood in the glass of water with alum have fused together.

Ning Changyuan knew that Gu Wanwan's mind was full of some whimsical ideas that he didn't know, so he didn't ask too much about this, and at this time, listening to Gu Wanwan's initiative to explain, he was a little puzzled.

What does it have to do with whether blood can be fused and whether there is alum in the water?

Gu Wanwan pursed her lips and smiled, proudly puffing up her little chest: "You don't know this, right?" Ordinary water is different from water with alum, and its acid-base properties are different. ”

"The water we drink every day is originally acidic, and the blood in our body is alkaline, so it is naturally impossible to blend together in the water."

"But as soon as we add alum to the water, the two drops of blood will naturally melt together. This is because alum is an alkaline substance, and when alum is added to the water, the water becomes alkaline, and then the blood is dripped into the water at this time, and no matter whose blood it is, it will eventually fuse together. ”

Have you learned a little common sense every day?

The so-called words "acidic", "alkaline" and "weakly alkaline" that came out of Gu Wanwan's mouth were something that Gu Mu and Ning Changyuan had never heard of.

The two people's reactions to Gu Wanwan's erudition were also different.

Although Gu Mu didn't have a big understanding after listening to it, he could be regarded as understanding the Ming Dao, and Gu Wanwan, who was the head of the Dao, admired it from the bottom of his heart. Gu Mu bowed deeply to Gu Wanwan, and couldn't help but say: "My lord is worthy of being an adult, I understand so many mysteries of everything in this world, I really admire it!" ”

"Alas, what are you talking about, it's a little meaning. Don't keep complimenting me like that, I'll be proud. Gu Wanwan was quite embarrassed to hear the compliment suddenly, so she pretended to be reserved and covered her mouth and nose and waved her hand, but her eyes were blazing and she stared at Gu Mu, expecting to hear more compliments from his mouth.

It's a pity that Gu Mu didn't understand Gu Wanwan's thoughts, seeing that she kept staring at herself, she just felt that there was something on her face, pinched her sleeve and wiped the tip of her nose Gu Mu asked weakly: "Adults keep looking at me, is there something on my face?" ”

"Nope! No, Gu Mu, you don't have anything on your face, only very handsome and very talented. Gu Wanwan laughed dryly twice and mixed up.

Gu Mu was quite embarrassed, Gu Wanwan waved her hand and motioned him out: "Gu Mu, go down first, I will let Zirui clean up the room for you, you go back and have a good rest, in two days it will be a banquet for you, and you will behave well when the time comes!" ”

"The villain must live up to his mission." Gu Mu said goodbye, and when he left, he didn't forget to close the door for the two of them.

As soon as Gu Mu left, Gu Wanwan looked at Ning Changyuan with a blank eye, her small mouth was round, her eyes were shining, and she was waiting for Ning Changyuan very expectantly.

"What do you see me doing?" Ning Changyuan looked away, pretending not to know what Gu Wanwan was thinking, and made up his mind to tease her.

Gu Wanwan pursed her lips, supported her chin with both hands, and said weakly: "His Royal Highness the Prince, how did you say the minister acted this time?" ”

"Not bad." Ning Changyuan spoke concisely and to the point, his expression was cold, his tone was indifferent, and he refused to say even a superfluous word.

Pretend, you just continue to pretend, you give it to me!

Ning Changyuan, you are a big sullen!

Gu Wanwan suddenly discovered that since Ning Changyuan confessed to her, Ning Changyuan's nickname in her heart has really changed and changed.

From the big devil, to the big scumbag, and now to the big sullen.

Miracles are far away, only what you can't think of, and nothing that he can't change.

Gu Wanwan snorted and winked at Ning Changyuan, her slender eyelashes flying up and down in Ning Changyuan's sight like butterfly wings. The flickering wings suddenly landed on his heart, tugging at his heartstrings again and again.

"His Royal Highness the Prince, since I performed quite well today, is there any reward?"

Since Ning Changyuan has always been unwilling to take the initiative to face her temptation, then she can only be direct.

I don't believe I asked so directly, you can still be so cheeky and not give me a reward!

But Gu Wanwan obviously underestimated Ning Changyuan's cheekiness, Ning Changyuan looked at her in amazement, and asked lightly: "Oh? Isn't this what you should have done, Lord Gu? ”

"This palace has never heard of any courtier who has completed his own work and dares to rush to find the master to ask for a reward."

Ning Changyuan gently hooked the corners of his lips and looked at Gu Wanwan with a smile.

Gu Wanwan looked at Ning Changyuan, raised her eyebrows slightly, and licked her lower lip with her tongue.

Okay, Ning Changyuan, you can do it!

"The minister has never heard of a courtier who has completed his own work, and the master does not give him money?"

Gu Wanwan looked at Ning Changyuan with a smile, her face was harmless to humans and animals, Ning Changyuan's face was also unfazed, and she couldn't see the slightest change in her expression.

"What should be given will always be given, but it's not time yet. Master Gu, don't be in a hurry. ”

Gu Wanwan and Ning Changyuan talked about it, and they carried guns and sticks between you and me, not leaving the slightest slack for the other party.

In the end, Gu Wanwan couldn't stand this way of speaking, she stood up, her eyes widened, she glared at Ning Changyuan angrily and shouted: "Ning Changyuan!" ”

"Gu Wanwan?" Ning Changyuan only needed to raise his eyebrows lightly, looked sideways at Gu Wanwan between the waves of his eyes, lowered his voice and lowered his voice, and in the blink of an eye, Ning Changyuan approached Gu Wanwan's eyes and asked, "What's wrong?" ”

Gu Wanwan pursed the corners of her mouth, laughed dryly, hurriedly took two steps back, and vaguely passed what happened just now.

"It's nothing, it's nothing, but I suddenly feel that His Royal Highness the Prince's name is really beautiful, so pleasant, and so literary. Suddenly I just missed a sentence. ”
