After getting out of bed, a human figure appeared on the memory mattress, no doubt it was the shape of Cheng Yanjin.

Cheng Yanjin watched the figure on the mattress slowly return to normal, and asked with a strange expression: "Qingquan, what's going on, why is my body on top of it when lying down?" ’

"Brother Cheng, you don't know, this mattress is called a memory mattress, a memory mattress, as the name suggests, is a mattress that can remember things by itself, you see if it remembers your body shape." Zhang Nan said with a smile.

Cheng Yanjin nodded.

"So, this mattress is much more comfortable than Simmons, Simmons is soft, but for the body, the memory mattress is much better for the body. The memory mattress can absorb the pressure on the human body, change the hardness according to the cold and heat on the person, and can also accurately shape the body contour, bring a stress-free fit, and give the body effective support, which has been medically proven to be effective in relieving musculoskeletal pain, assisting in the treatment of cervical and lumbar spine problems, reducing insomnia such as snoring and turning over, prolonging deep sleep time, and improving sleep quality. ”

Zhang Nan naturally couldn't remember so many advertising words, Zhang Nan was completely reading the instructions of the memory mattress, and nodded again and again.

Cheng Yanjin has been marching and fighting outside all the year round, and it is impossible to say that there is no problem, so how good can the rest conditions be when fighting outside? Therefore, a comfortable bed is something that Cheng Yanjin can meet but cannot find.

"Qingquan, you say, how many silver taels does this memory mattress cost, you can give Brother Cheng five first." Cheng Yanjin said with a wave of his hand.

"Five? Brother Cheng, do you want to take it with you when you go there? It's enough to have one of these things at home. Zhang Nan said with some surprise, after all, who would buy five mattresses to put at home?

"That's not it, I just want to give one to each of my brothers who have been fighting with me for many years, my body is not bad, you look at the second brother, he is sick, when it rains on a cloudy day, let alone sleep, it is difficult to walk." Cheng Yanjin explained.

When Zhang Nan heard this, he suddenly realized.

"I see, let's say, isn't it five? Brother Cheng, you are not an outsider, I will give you a discount for relatives and friends, and ensure that you will not suffer a loss. And this mattress is not something you can put on those small beds in your house, so I'm giving you five beds for free. Zhang Nan leaned over to Cheng Biting Jin's ear and said with a mysterious look.

"Hey, I like your generosity." After Cheng Biting Jin finished speaking, he was about to slap Zhang Nan again, Zhang Nan hurriedly dodged away, joking, this slap is not a joke, Zhang Nan doesn't want to experience it for the second time.

"A mattress is 100 yuan, Brother Cheng, you are your own person, even if you are 80 yuan, five is 400 yuan, how about it, is there a problem?" Zhang Nan said with a smile.

"Four hundred? Meaningless, you first have someone send this mattress to my house, and then I will send you the money to your house. "Cheng Biting Jin is also very bold, although there are more than 400 guan, but for a grandfather like Cheng Biting Jin, he really didn't pay attention to it.

As the Duke of Lu Guogong of the Tang Dynasty, Cheng Biting Jin's status is naturally needless to say, and Li Er will definitely not lose Cheng Biting Jin's money, not to mention that Cheng Biting Jin's family wealth is not only given by Li Er, as a general who marches and fights, the best thing is that the spoils of war after winning the battle have the right to dispose of them independently.

In addition to the part that must be handed over to the imperial court, a large part of the spoils will be distributed by the general to his soldiers to improve loyalty and maintain combat effectiveness, so there is more room for maneuver.

Zhang Nan didn't believe that Cheng Yanjin hadn't caught anything in the battle he had fought for more than ten years, and 400 guan was really a small thing for him.

"It's a lot of four hundred." There was an exclamation from behind Zhang Nan, Zhang Nan turned his head, only to find that Fang Xuanling and Xiao Yu were no longer drinking tea, but they didn't know when they came to him and Cheng Yanjin's side.

"Ah, I bought a few beds here in Qingquan." Cheng Biting Jin buttoned his nose and said with a relaxed look.

"A few beds actually cost four hundred, Qingquan thinks about money and wants to go crazy." Xiao Yu obviously couldn't understand the sky-high price of selling Zhang Nan's beds for 400 yuan.

"How can this be that I'm crazy about money? This is clearly worth the money, if Lord Xiao doesn't believe it, you can experience it yourself. Zhang Nan said.

Obviously, Xiao Yu's final experience turned out to be that he also spent eighty yuan to get a memory mattress at the price of Zhang Nan's relatives and friends, and then asked Zhang Nan to give him a bed as well.

Yu Shinan and Fang Xuanling were obviously more interested in Zhang Nan's sea of tea made from tree roots.

In the end, Zhang Nan also used twenty times to let Yu Shinan and Fang Xuanling take a sea of tea, just when Yu Shinan and Fang Xuanling were thinking about whether to buy a memory mattress to take home, Zhang Nan's small shop ushered in the biggest customer.

It is also the guest that Zhang Nan is most reluctant to see, because this guest is very likely not to pay.

"Ladies and gentlemen, you are running quite fast, this supermarket has just opened, and you are here."

The voice came, everyone looked back, only to find that Li Er appeared at the staircase in his usual clothes, everyone went up to salute Li Er, and Li Er also raised his hand, signaling that everyone did not need to be polite.

"Qingquan, what's new in your little shop?" Li Er said as he stretched his neck to look into Zhang Nan's store.

"Hey, what's new, these are just ordinary furniture, do you want to buy some and bring them back to the palace?" Zhang Nan also gave Li Er a preventive shot in advance, and first explained in advance that these things had to be paid, otherwise if Li Er just took it away directly, Zhang Nan would not have to die.

"Rong Zhen will take a look first, if there is something I like, I will naturally give you no less." After Li Er finished speaking, he walked towards the store.

"What you mean is that you don't pay if you don't like it." Zhang Nan complained fiercely in his heart.

Li Er entered the store, but did not walk in the direction of the mattress, but walked towards some small handicrafts that Zhang Nan placed on the shelves. As he walked, Li Er saw something that attracted his attention.

"This horse is a miracle horse, I want it, I don't have any other hobbies but I like horses." Li Er pointed to a crystal horse and said.

"Eh, okay, no problem, Emperor Wubaiwen, you will let people take this ornament to the palace." Zhang Nan said.
