Sitting on the cross-border trading group, the country is chasing after it

The next morning, Jiang Ruochu saw the message in the group and sent a message to Cui Xuehui without even washing his face.

Jiang Ruochu (Modern World): What medicine do you need?

Cui Xuehui (The End of the World): Great! You are here! I need cold medicine and fever medicine, and a mask.

Cui Xuehui (Apocalyptic World): Although you prepared some medicine for me last time, it is not enough to deal with the large-scale infection of survivors.

Cui Xuehui (Apocalyptic World): During this period, all the active people in the base went out to look for medicine. If they couldn't find the medicine, even if they were not bitten to death by zombies, they would not be able to survive.

Cui Xuehui (Apocalyptic World): Alas, we are now in a fight with the virus.

Zombie virus, flu virus, all kinds of viruses. Cui Xuehui felt that the world she lived in was really full of holes.

In the last days, the relationships between people will become very strange. There will be vigilance, but there will also be a need for cooperation and trust.

In the doomsday world, not all the people she met were people who didn't care about her life or death.

When she was out searching for supplies, there were teammates who volunteered to stay behind and let her go first when she was besieged by zombies; there were also neighbors who were willing to share a bowl of plain porridge with her when she was sick and unable to go out to participate in the mission.

It’s okay at normal times, but if the situation really becomes necessary, will Cui Xuehui share some of her supplies to keep them alive, or watch her teammates and neighbors die?

After thinking it over again and again, she couldn't be so cruel.

Jiang Ruochu (Modern World): I'll buy the medicine for you now.

Cui Xuehui (Doomsday World): But we still have seven or eight days before the next transaction. What should we do?

Jiang Ruochu (Modern World): I will discuss it with the system.

Everyone in the group knows that Jiang Ruochu has a system, which is also the origin of the establishment of their time-travel chat group.

Jiang Ruochu called out affectionately: "Xiao Tongzi~~"

The system popped up and asked cautiously [What are you going to do? ].

"I just thought about it, the rule of trading once a month is a bit unreasonable."

The system did not relax its vigilance. It would never forget how it was fooled by Jiang Ruochu.

[Impossible! I wrote every rule with great care and it has been verified by many peers. How can it be unreasonable? You don’t want me to trade once a week, do you?]

"How is that possible? I'm not that greedy. I still trade once a month. But I thought about it carefully. Your month is calculated as thirty-one days."

[Yes, what’s the problem? ]

"But some months have 28 days, some months have 30 days, and as the days go by, the number of transactions per person is actually decreasing."

"We calculate based on a 117.7-day year and a ten-year period. If a cycle is days, the total number of transactions is times."

"If a thirty-day period is taken as a cycle, the total number of transactions is 121.6 times."

"If we take 130.3 days as a cycle, it would be even more amazing, with a total of transactions."

The system felt that it was being led into a trap, and it shouted in frustration, "You are so good at calculating, I think you are awesome!"

"Thank you for the compliment." Jiang Ruochu responded cheekily, and then continued to analyze with the system, "So is this month set at 30 days, 31 days, or 28 days? No matter which number of days is set as a cycle, it is unreasonable."

"Besides, what about our fellow time travelers thirty-one days later?" Jiang Ruochu pronounced the word "fellow travelers" so forcefully that the system's sense of responsibility seemed to rise.

"They don't have anything they want to trade for now, so if the trading date continues to be postponed, won't they be at a loss?"

"If they lose, then you, Xiao Tongzi, are also the ones who lose." Jiang Ruochu raised his eyebrows, "Points, understand?"

【…】

【You continue.】

"Why don't we just calculate it by month?"

"No matter what date the time traveler and I trade in a month, we can trade again as soon as the next month comes."

"This way there will always be twelve months in a year, which is fair and just."

"It's highly flexible, and the travelers can use it at their will. It's also convenient for you to count the number of transactions."

The system was silenced by Jiang Ruochu.

[You are so kind. You tried so hard to help me think of a reason. ]

Jiang Ruochu pretended not to hear the system's ridicule and coughed lightly: "Anyway, this is a great thing that benefits both people and the government!"

[Okay, okay, I get it. I'm afraid that if you continue to fool me, I'll be able to calculate thirteen months in a year.]

Jiang Ruochu said righteously: "How could it be! I won't make up stories and say white is black and black is white."

[Is that OK? Our transactions are calculated by month. Now we are in July, so travelers who have completed transactions in June can choose any day in July to trade.]

Of course, the system was not entirely dependent on Jiang Ruochu's "trickery", but the problems raised by Jiang Ruochu did exist and constructive suggestions were given.

Being a learned, kind, and reliable system, it accepts reasonable opinions.

Jiang Ruochu happily shared the news with the time travelers in the group.

Jiang Ruochu (Modern World): Friends! From today on, our transactions will be based on the month, which means that no matter which day in June you trade, it will not affect the trading day in July.

Jiang Ruochu (Modern World): Everyone can arrange their trading time freely.

Immediately afterwards, Jiang Ruochu added detailed explanations of the trading rules in the group announcement.

Yuan Tangtang (Ancient Palace Fighting): Wow, that's great! This way Sister Cui can get the medicine right away.

Meng Xuan (Empress's World): This is quite convenient. I don't have to scratch my head wondering what I should change in a month. Instead, I can think about it slowly throughout July, and even wait until I need it urgently before changing it.

There is also an advantage for Jiang Ruochu by doing this, that is, as long as Zhong Zhen's Qi-nourishing and Rejuvenating Pill is ready, it can be delivered to her immediately, without having to wait for another thirty-one days.

Jiang Ruochu couldn't help but poke Zhong Zhen from the Xiuxian World with joy, and then she received an automatic reply from Zhong Zhen: Chasing the big carrot that ran away, don't disturb~~ (I don't believe I can't catch up with you carrot!)

Jiang Ruochu: "..."

Student Xiao Zhong is very busy!

Jiang Ruochu (Modern World): Let us be grateful for the great and considerate system!

Yuan Tangtang (Ancient Palace Fighting): Thank you for the great and considerate system!

Meng Xuan (Empress World): Thank you for the great and considerate system!

Cui Xuehui (Doomsday World): Thank you for the great and considerate system! Thank you very much!!

[Group system announcement: Ding! Building a harmonious and beautiful chat group is inseparable from the good group members who help each other! As of now, this group has 9999 chat records, and the friendship value of the whole group has reached 600. The group atmosphere is healthy and positive. In order to further enrich the spiritual and cultural life of the majority of group members and build a larger and stronger chat group for travelers, this group is about to expand a new group member. 】

【Let us warmly welcome Fu Yanxi (Fairy Demon Sadomasochism) to join our group! 】

Jiang Ruochu (Modern World): This name gives off the aura of sweeping across the three realms.

Yuan Tangtang (Ancient Palace Fighting): Sadomasochism! My eyes widened like bells.

Zhong Zhen, who was idle in the group and busy chasing carrots, received a strong interruption of the system announcement - a large banner announcement with colorful colors and voice broadcast.

When she saw that it was a colleague, she was surprised.

Zhong Zhen (World of Immortal Cultivation): Is he a fellow Taoist or an immortal senior whom I need to look up to?

Fu Yanxi (A Sadistic Love Between Immortals and Demons): …

Fu Yanxi (A tragic love story between an immortal and a demon): Sorry, I am a demon.
