I hand over the Wanjie trading system to the country

"The current time is 6:5." Chu Cheng was the first to realize and recorded the current time.

"They can't be in the supermarket all the time, they will be ejected when the time comes."

"You can eat and drink in the store, but you can't leave with anything that doesn't belong to them."

"Their things can stay, but whether they can keep something of value or anything remains to be determined."

"I gravitate towards something of value, like paying us."

"Agreed, we sell stuff, they pay, no problem!"

"And this is called Myriad Realms Trading System, trading, this is the key point."

"Then can we not collect money ourselves, or what will happen if they don't take the initiative to pay?"

"Also, this value is not easy to define, there is no standard."

"That's right, that person yesterday ate at least 40 yuan, but only gave him two copper coins."

"Today, this has turned into barter, and I don't know how much it is worth. The shelves are all smashed, and there is blood all over the place."

"Hey, this is a cultural relic, so it can't be counted that way." Father Chu retorted.

"Yes, cultural relics worth 10 yuan." Mother Chu joked with a smile, "Are you still lacking research on Qianlong Tongbao? It's still Xiaoping money."

"Can this... cultural relic be measured by value?" Father Chu said angrily.

Everyone talked about the problems they found and what questions they had at present.

Chuno took a notebook and recorded them one by one, and verified them one by one when he had the opportunity.

The sky was getting brighter and brighter, and the family of four who hadn't slept all night packed up the supermarket and went to have breakfast together.

Then those who should go to work go to work, and those who don't go to work go home and sleep.

Guo Fu and his two daggers were taken back to school by Father Chu for testing.

Chu Cheng was more thoughtful, and took the gauze left by Zikang to the unit for testing to see if anything could be detected in Zikang's blood.

Only Chun Nuo could go home and sleep. He was so sleepy that he woke up after taking a bath.

After thinking about it, Chunuo turned on the computer and carefully recorded what happened in the past few days.

I even made a super complex mind map, listing all the possibilities I can think of.

What Chuno was most curious about was whether those people came from the past or from the parallel world.

People who are doomed to die in history, because they came to the supermarket and survived, will this change the ending of an era?

"What's this called? Schrödinger's butterfly? Haha!" Chuno was confused by his own imagination.

Thinking about it, Chuno leaned on the sofa and fell asleep.

"Do these people only show up at night?" After waking up and going to the supermarket, thinking about this problem, Chuno turned on the computer and began to study it seriously.

In the Wanjie trading system, [Trading interface] has changed to {Unlocked 2}, but there is still no way to click in.

I don't know if it's just these contents, or it can't be opened because there is something unlocked.

[Mall] is still not open, and [Auxiliary Function] is still the same as before.

"Hey~" Chuno sighed as he pinched his chin with his hands.

Then he rubbed his face and watched the surveillance video from the previous two days again.

The surveillance video of the supermarket can be saved for 30 days and overwritten automatically. The video of these two days has been downloaded and saved in a USB flash drive for easy research.

At 7:[-], the Chu family all came to the supermarket, and the employees of the supermarket left work early.

Secrecy is one aspect, and the second is that every time a "traveler" comes, only the Chu family is there, and I don't know if there is any connection.

The previous two times were after the supermarket employees left after get off work, someone came around 10 o'clock.

The purpose of this advance is to see if there will be only the Chu family left in the supermarket ahead of time, will anyone come early.

There is one more thing to verify tonight. Is it only possible to trade once a night, or several times?

Also see if people from the modern world can't come in as long as there are people from another world in the store.

However, the previous two times were relatively late, and there is no way to verify this for the time being. I came here earlier tonight to see if customers from different places can come to the store to trade together.

"I don't know which dynasty will come tonight." Father Chu touched his chin and said, looking forward to it.

"The previous two times belonged to the Qing Dynasty...could it just be a dynasty in history?" Chu Cheng guessed.

"The system is out, maybe there is something about the interstellar era? For example, aliens or something." Chuno said.

"Interstellar age? It's interesting." Mother Chu's eyes lit up.

For researchers like them, the interstellar era is very attractive.

"It's so exciting, it feels like opening a blind box." Chuno laughed.

"Why don't we make a bet and guess who is here today?" Chu Cheng suggested, "Give us a supper!"

"I bet on the Qing Dynasty!" Chuno spoke first.

"Aren't you playing tricks?" Chu Cheng glanced at Chun Nuo with disgust.

The previous two visits were all from the Qing Dynasty. If there is no accident, it is very likely that the ones who came this time are also from the Qing Dynasty.

"Then...then I guess that during the Yongzheng period, after all, it was a high incidence period!" Chunuo thought for a while and said, "I guess the specific time period, this is not a shame."

"That's about the same." Chu Cheng smiled and nodded.

"Then I guess Xuantong!" Father Chu laughed.

The first time was Qianlong, the second time was Guangxu, after Guangxu, only Xuantong came.

"I'm not like you, I guess Kangxi." Mother Chu looked at Chu Cheng after finishing speaking, "Son, what about you?"

"Me? Then I guess the period of the Republic of China." After Chu Cheng finished speaking, he added, "This is not a foul for me, it is already in modern times."

"Hmph, clever!" Chuno rolled his eyes at his brother.

"Girl, don't roll your eyes, and you'll get used to it in the future!" Mother Chu patted Chuno on the shoulder lightly.

The family chatted without saying a word, and the time slowly came to 8:[-].

"Crash!" Suddenly there was a loud bang at the door, and the glass door shattered to the ground.

Immediately, smoke and dust rose everywhere, and it was impossible to see what was inside, only a burst of roaring sound could be heard.

Chuno screamed, then pulled his mother over and squatted behind the cash register.

Father Chu was also taken aback by this sudden change, and froze in place for a while, not knowing how to react.

After reacting, Chu Cheng quickly raised the shield with one hand to block himself and his father, and tightly held the stick with the other hand.

In order to deal with emergencies, Chu Cheng specially bought a set of security patrol equipment from the logistics department of his unit today.

Explosion-proof shield, explosion-proof fork, throwing stick, bright flashlight, restraint belt, first aid kit.

Except for some special standard appliances, everything should be there.

"Dad, go quickly, squat down behind the counter, protect yourself, leave this to me."

"Okay, you pay attention to safety." Father Chu hurriedly left after reacting.

At this time, if he had to stay, it would not be a help but a hindrance.

After all, Chuno is the captain of the special police, and if he doesn't need to be distracted to protect others, his fighting power is not for nothing.
