It's uncertain if there will be any subtle differences in this place's world.
If everything is truly restored, then Ye Tiancheng and the others would be in extreme danger.
Upon realizing this, Nie Chongyang and Liang Ping couldn't help but feel worried. No matter how capable Ye Tiancheng and his companions were, war was a merciless thing. If the flames of war were to spread to them, it wouldn't be a minor issue.
They were genuinely afraid that Ye Tiancheng and the little fox might encounter any accidents.
Liang Ping said, "We can only trust that they have discretion and capability. If there's real danger, they should try to avoid it and find a way to resolve things quickly. Leaving that place might not necessarily lead to trouble."
Nie Chongyang nodded and replied, "Let's hope so."
Besides that, being separated by two timelines and existing on different timelines, there was nothing they could do to help each other.
After reading the letters, Nie Chongyang and Liang Ping discussed them. Then, they took out their own stationery and pens, pondered for a moment, analyzed the clues for Ye Tiancheng and the others, and then wrote down their own clues to let Ye Tiancheng and the others see.
This way, the value of the communication could be maximized.
As for their own situation, it was mostly related to Ding Yijie, which definitely needed to be written down. They also had to mention any special attitudes present there, such as the excessive attention paid to the ruined hotel, which went beyond the normal scope.
After finishing, the two of them reviewed the letter's content, filled in any gaps, and then sealed the letter in a new envelope.
That's right, a new envelope.
When they had communicated with Ye Tiancheng before, and when Ye Tiancheng and the others had sent letters back again.
It was unclear whether it was because the letters could be transmitted unscientifically, but the envelopes were strangely as if they had been enduring the erosion of time. Whenever they reached Nie Chongyang and Liang Ping, the envelopes would be even more aged and worn.
They strongly suspected that if they were to replace the envelopes again and send the letters back this time, the envelopes might simply rot away.
In reality, they would not.
Nie Chongyang and Liang Ping were unaware that only the envelopes enclosing letters sent from the past to the future would age and suffer severe damage. However, when the envelopes were in Nie Chongyang and Liang Ping's hands, they would be in the same condition when sent back to Ye Tiancheng and the little fox.
This was because they were things sent back from the future to the past.
Therefore, the situation was different.
The two of them put the letters into new envelopes and sent them back again. Nie Chongyang even added a note on the letter, asking Ye Tiancheng and the others to remember to change the envelopes. Otherwise, after a few more transmissions, the envelopes would be severely worn, and they might not be able to preserve the letters well next time.
As expected, after Nie Chongyang and Liang Ping sent the letters, they watched as the letters disappeared before their eyes.
Nie Chongyang couldn't help but say, "Ye Tiancheng and the others are really waiting on that side."
Liang Ping replied, "If it were us, seeing that scene, we would probably be willing to wait and see. Unless we didn't have the conditions, we would give up on that choice."
As he said this, Liang Ping suddenly had an idea.
He said, "However, if this is the case, and since we two, along with Ye Tiancheng and the little fox, are all staying in the same location, allowing us to transmit messages in real-time, and if we receive letters, does that mean..."
At this point, Liang Ping paused slightly.
Nie Chongyang and Liang Ping looked at each other.
The next moment, Nie Chongyang tore off a small piece of paper, wrote a sentence on it, and threw it towards that place. The paper read, "Can you receive this?"
After throwing the paper, it disappeared before their eyes within a few seconds.
Then, after a short while, a piece of paper rolled back out from that place. Nie Chongyang and Liang Ping opened it and found it written, "Received."
This made the two of them stunned again, looking at the paper in their hands.
They had truly not expected this idea to actually work. As long as Nie Chongyang and Liang Ping, as well as Ye Tiancheng and the little fox, were all staying in the same place across different timelines, they could transmit messages there and ensure the other party received them in real-time.
This was too miraculous.
Nie Chongyang said incredulously, "Doesn't this mean we can have real-time chats with Ye Tiancheng and the others by passing notes?"
Liang Ping nodded.
"We certainly can."
He was also quite shocked, not expecting to have such an experience in his life.
He had never passed notes in class his entire life, and now, he was experiencing the feeling of chatting by passing notes.
Since Nie Chongyang and Liang Ping had seized this opportunity, they would certainly not give it up easily. They still wanted to take this chance to chat more with Ye Tiancheng and the others, as they might not have such a coincidence next time.
Therefore, Nie Chongyang immediately took action, wrote another small piece of paper, conveyed their intentions, and sent it over.
Soon, they received a reply.
Nie Chongyang and Liang Ping, and Ye Tiancheng and the little fox, hit it off perfectly. Both sides realized this matter and had the same thought.
Such a good opportunity, wouldn't it be a pity not to use it?
They decided to act immediately. Ye Tiancheng and the others, and Nie Chongyang and his side, began to chat by passing notes across time at the overlapping point of the same space.
When Ye Tiancheng and the others had gone to send the letter, they noticed that Nie Chongyang and the others had immediately taken the letter. This made them realize that Nie Chongyang and the others might be on that side, so they decided to stay and see if they could receive a letter from Nie Chongyang and the others.
As expected, without waiting too long, when the little fox, who had nothing to do, went back to check, he saw a brand new envelope appear at the place where they transmitted messages.
The little fox immediately picked up the letter, while also taking care of his elder brother, Ye Tiancheng.
"Brother! Come quickly! The letter is here!"
Ye Tiancheng and the little fox, carrying their small stools, sat down by that spot and opened Nie Chongyang's letter to read it.
Upon discovering that Nie Chongyang and the others were in a much safer situation, Ye Tiancheng and the little fox felt quite relieved. It was good that they were fine, and the dangers on their side should be within their ability to handle. This way, Ye Tiancheng and the others wouldn't have to worry about any accidents happening to Nie Chongyang's side.
Then, looking at the content of the letter, Ye Tiancheng and the little fox learned that Nie Chongyang and Liang Ping had met Liang Ping's relatives who had long passed away in reality.
Those people had been dead for about twenty years.
Looking at the matters involved, Ye Tiancheng and the little fox felt that this should be the direction of the clues that Nie Chongyang and Liang Ping could investigate, and it should be a relatively important point.
However, before Ye Tiancheng and the little fox could finish reading, the little fox suddenly said, "Why is there another note?"
Ye Tiancheng looked towards the place where they transmitted messages with the little fox, feeling puzzled. Indeed, they saw a small piece of paper rolling out.
The little fox picked it up and read, "Can you receive this?"
Ye Tiancheng and the little fox were slightly stunned, then they both realized. That's right, they were both staying in the same place, and could instantly receive each other's letters. Therefore, in theory, notes could also be passed.
If that was the case, couldn't they chat in real-time?
Such an opportunity was very rare.
So, they immediately sent back a note, which read, "Received."
This was a significant discovery. Moreover, if they could grasp the pattern, wouldn't they be able to gather at this place regularly and chat by passing notes, exchanging information in real-time?
This method of communication was much more convenient than writing letters.
Since they had discovered this, Ye Tiancheng became the one to read the letters, identify the key information, and tell it to the little fox. The little fox would then guard that spot, looking for any notes to appear and see if Nie Chongyang and the others had anything else to convey.
Without waiting for long, the little fox saw new notes appear.
Following the appearance of the new notes, a very old small note also rolled out.
The little fox found it a bit strange. He first picked up the old one and saw that it was very tattered, but he could still vaguely make out that it was a note he had replied with earlier. He didn't know what had happened, but it had become this worn out after one round trip.
He then opened the note sent by Nie Chongyang and the others. Nie Chongyang had written on the note, "When you transmit messages, please provide some packaging. It might be because these things, when transmitted, undergo the erosion of time. By the time they reach us, they are already very old. For letters, at least there is an envelope to wrap them."
"But for notes, if there is too much content on them, some things will inevitably be missed."
"We mentioned this in the letter and suggested changing the envelopes. You might not have seen that part yet, so I'm reminding you early."
The little fox then realized that there was such a thing.
In fact, they should have had some feeling before, but when they received Nie Chongyang's reply for the first time, Nie Chongyang and the others had not changed the envelope and had put the new letter into the envelope.
Therefore, Ye Tiancheng and the little fox had not paid much attention to this matter.
After all, the two of them had come in the dark.
In that case, they would definitely not notice what the envelope looked like. After all, envelopes buried in such a place would surely become dirty and old. If they weren't careful, Ye Tiancheng and the little fox, fumbling in the dark, would not even notice such a thing.
However, now that Nie Chongyang and the others had reminded them, Ye Tiancheng and the little fox were both aware of this matter.
After the little fox informed Ye Tiancheng about this, Ye Tiancheng flipped through the letters left by Nie Chongyang and the others and indeed saw this remark at the end.
However, Ye Tiancheng thought for a moment and said, "But I see that they changed to a new envelope, and when it arrived, it didn't seem to have suffered any damage. It's still new, with no signs of aging."
The little fox thought for a moment and suddenly had an idea.
He said to Ye Tiancheng, "Brother, do you think this situation might be because they are sending letters from the future to the past? So theoretically, the letters shouldn't exist, but they do, yet they won't be eroded by time, so everything is still new."
"But it's different when we send messages to them."
