"Mr. Tang, this soap...... What is it? ”

Wei Qing asked Tang Qi with some embarrassment.

Tang Qi suddenly frowned and said, "At this time, you are still playing a hammer, don't you know about soap?" ”

Wei Qing was stunned: "I didn't act, I really don't know what soap is, Mr. Tang, you can tell me clearly!" ”

"I'll give you a lung!"

Tang Qi rolled his eyes and explained: "The soap is white, square, the kind that smells of a fragrance, you can wash clothes, it's on my windowsill, you can see it when you go in!" ”

Wei Qing suddenly said: "Understood, I'll go get it now, please wait a moment, sir!" ”

Before the words fell, Wei Qing had already run away.

He is really loyal to Liu Che, for fear that something will happen to Liu Che.

After Wei Qing left, Liu Che said to Tang Qi in a weak voice: "Mr. Tang, I ...... Will it really be okay? ”

Tang Qi sat on a stone pier, crossed Erlang's legs and said: "Don't worry, with me, you will definitely be fine, I don't want our future cards to be missing one!" ”

Liu Che reluctantly pulled the corners of his mouth and smiled.

With Tang Qi, an immortal, as a guarantee, Liu Che can also rest assured.

As long as you don't die, you can say anything!

Soon, Wei Qing grabbed a piece of white things and ran into the cave with a basin of water.

He first put the water in front of Liu Che's bed, and then stretched out his right hand at Tang Qi and said, "Mr. Tang, you see that this thing I am holding is soap, right?" ”

Tang Qi glanced at it and said helplessly: "My brother, you really know how to take it, let you take a soap, you are stunned to bring a soap, it is also amazing!" ”

"Huh?"

Wei Qing was stunned and said, "No, I'm ...... I saw two white things on the windowsill, and I ...... I just took a piece casually, and there seems to be no difference between the two! ”

Tang Qi sighed and said: "The difference is big, it's all because I didn't make it clear to you, but the soap really can't be used, it's not alkaline enough, you can run again and bring me the soap!" ”

Soap is obtained after saponification reaction with sodium hydroxide and grease, and the alkalinity is about 3%.

When a non-venomous bee stings a person, it leaves a layer of acid on the wound.

Washing the wound with alkaline soapy water will neutralize the acidity, avoid aggravating the injury, and somewhat relieve swelling.

And because soap is used to wash the face and bathe, it is relatively weak in alkalinity and close to neutral.

Washing the wound with soapy water has little effect.

After Tang Qi finished speaking, Wei Qing didn't say a word and ran out of the cave again.

As for the piece of soap, it was naturally left in front of Liu Che's bed.

Wei Zifu curiously picked up the soap and looked at it, and a scent of flowers directly hit her nose.

"It smells so good!"

Wei Zifu praised it, then looked at Tang Qi and said, "Mr. Tang, is this a delicacy made of flower petals?" ”

This girl has now released her foodie nature, and she asks if she can eat anything she sees.

Tang Qi waved his hand and said: "This is not a delicacy, you will have a stomachache if you eat it, you must not eat it, it is mainly used to wash your face!" ”

"Wash your face?"

Wei Zifu looked at the soap again and wondered, "How do you wash your face with this thing?" Do you have to dip in the water? ”

Tang Qi shrugged his shoulders and said, "Almost, first dip some water, then rub out bubbles with your hands, then pounce on your face and rub it, and finally rinse it with water, and your face will be clean!" ”

Wei Zifu asked, "How clean can it be?" ”

This stunned Tang Qi.

How do you answer that?

After being stunned for a while, Tang Qicai scratched his head and said: "How to say it, at least it is cleaner than pure hand rubbing, the oil and blackheads on the face can basically be washed off, and the face is still fragrant after washing, and the skin will be tender!" ”

Wei Zifu's eyes lit up instantly.

"Is Mr. Tang serious? Does this soap really make your skin smooth? ”

Wei Zifu asked Tang Qi excitedly.

Tang Qi nodded and said, "Of course you can, when I made the soap, I added the essential oil of the moon flower and the essential oil of rose, and the effect is very good!" ”

Although Wei Zifu didn't understand what essential oil was, he probably understood that what Tang Qi said should be true.

"Mr. Tang, this soap...... Can you give it to me? I'm willing to give 10,000 gold in exchange! ”

Wei Zifu asked Tang Qi expectantly.

Tang Qi smiled: "This piece of soap must not be given to you, I have already used it, I will give you a new one!" ”

Wei Zifu was suddenly pleasantly surprised: "I take Mr. Tang's words seriously, I'll wash my face with soap later!" ”

At this time, Liu Che said weakly: "Mr. Tang, can this soap wash away the toxins on your face?" I feel that my face is getting more and more painful, why don't I wash it with soap first! ”

Tang Qi took a closer look and found that Liu Che's face was indeed a little swollen again, inexplicably a bit like Xiao Yueyue.

Tang Qi wanted to laugh again.

But in order to avoid irritating Liu Che, Tang Qi still couldn't help but smile and said: "You wait a little longer, Wei Qing will bring the soap over immediately, it will be better for you to wash your face with soapy water!" ”

Liu Che couldn't help but ask, "Mr. Tang, what is the difference between this soap and soap?" ”

"Well...... this"

Tang Qi touched his chin and said: "The difference between the two is probably the strength of alkaline, you probably can't understand what I said, anyway, you just remember that soap is mainly used to wash clothes, and soap is mainly used to wash your face!" ”

Liu Che's eyes widened and said, "Mr. Tang, it's not good to wash my face with laundry things, right?" ”

Tang Qi pouted and said, "There's nothing bad, why do you care so much about your face as a big man?" ”

Liu Che stiffened his neck and said, "I am the emperor of the dynasty, how can I not pay attention to my appearance?" ”

"Ah!"

Tang Qi shook his hand and said: "Washing your face with soap won't disfigure, the effect is actually similar to soap!" ”

Liu Che was skeptical, and always felt that Tang Qi was deliberately comforting himself.

At this moment, Wei Qing rushed in again.

This time he did bring the soap.

Tang Qi didn't waste time, and directly washed Liu Che's face with soap.

Of course, in the process of washing his face, Tang Qi was not particularly gentle, and screamed at Liu Che in pain.

If it weren't for Tang Qi's identity as an immortal, Liu Che would have asked Wei Qing to cut Tang Qi a long time ago.

Growing so big, it was the first time for Liu Che to feel so painful, and he was very aggrieved.

Fortunately, after washing his face, the swelling on Liu Che's face did subside a little, and it was not as funny as before.

Tang Qi threw the face towel aside, and asked with a smile: "Okay, you shouldn't be in any danger now, can you tell me why you went to poke that honeycomb?" I'm curious! ”

Liu Che rubbed his face, sighed and said: "I just wanted to see if there was honey in the hive, but I didn't expect the honey to be seen, I saw a group of bees first, it was really unlucky!" ”
