Su Yuan and the others only stayed in the study for half an hour, then politely refused Zhou Wan's invitation to leave for a meal and hurriedly left.

After Su Yuan and the others left, Zhou Wan nagged to Gao Xiang, "What the hell is going on? Why do the two children have something to do to find you, a great scientist? Seeing that they were so anxious that they didn't even have the heart to eat a meal!"

Gao Xiang glanced at her and said angrily: "They are adults, so of course they have their own ideas."

Zhou Wan couldn't help laughing, "Look at the girl who was with Xiaoyuan just now, do you have the hope of being our daughter-in-law?"

"I don't know if she has hope. The key is whether Xiao Junnu works hard or not! However, there is one thing you must have made mistakes. The one who came here just now was not Xiaoyuan, but Xiaoyuan's 'sister' Xiaomei!"

"Is Caiwei's daughter just found?"

Seeing Zhou Wan's shocked expression, Gao Xiang raised the corner of his mouth slightly, "Have you seen it at the engagement banquet? Didn't you recognize her?"

Zhou Wan nodded in surprise and said, "I thought it was Xiaoyuan when she came with that Xia Linwo."

After leaving ZTE Garden, Su Yuan and Xia Linwo sat on the white Audi TT and drove slowly along the trail. This time they came to look for Gao Xiang, but they did not get much gain. However, the information they obtained from Gao Xiang confirmed that the reason for the thirteen hours of September 5th may be that there was a time-lapse in the solar system.

"Sister Xia, will this local time-rewind cause changes in the world line value?" Su Yuan suddenly asked while driving.

This question seems meaningless at first glance, but in fact it involves the essence of the world line.

Charlene thought for a while and replied: "In theory, even the slightest time flows back will cause substantial local historical changes. The world line value is a physical quantity that represents the entire world, and local changes are also a small part of the whole, so it should be reflected on the world line, but..."

"But what?"

"You think. The universe is so big. Although the solar system is big enough for us, it is just a very small drop in the vast sea of ​​stars. After the solar system goes back in time, the absolute value of the world line value will definitely change, but the world line olfactory may not be clearly presented on the world line olfactory."

Su Yuan understood that it was because the sensitivity of the world line olfactory was not enough. The reflux on September 5th was not like the subsequent crossings, which caused space-time changes in the entire universe. It was limited to a solar system and had extremely limited influence. The world line olfactory had only seven digits in total, and could not show such insignificant changes.

In other words, the world line changed on September 5th, but it changed very slightly.

The car was driving on the road, and the carriage was quiet. After a silence, Xia Linfei suddenly said, "Su Yuan, take me to see the time machine you are riding in."

Su Yuan focused on holding the steering wheel and said unexpectedly when he heard this: "That unit is on the hillside."

Charlene nodded, "I know, there may be some inconvenience along the way, but I have to go over and take a look!"

"The second time machine should not appear in this world. If I guessed correctly, the time machine that brought you to this era is probably the one I rode on! I remember that time machine has a recording function and can record the world line data after crossing at the first time. Whether it is the same time machine can be seen with your own eyes."

"So that's the case!" It's really necessary to go over and take a look.

The two of them no longer hesitated. While it was still early, Su Yuan and Xia Linfei went straight towards Phoenix Mountain.

The car parked at the door of Lao Liu's house in Xiaoqiao Village, at the foot of the mountain that had helped Suyuan last time, and bought some dry food. The two of them went up the mountain in a dusty manner. They walked along the foothills and climbed for half a day. Finally, they arrived at the place where the time machine resided before dark.

The site has been maintained with a shed, and there are people arranged by Su Caiwei to protect it at all times. When the staff saw Su Yuan, they received a notice from Su Caiwei early, and the on-site personnel did not come forward to stop him and allowed the two of them to go straight into the shed.

The huge metal ball lies in the depression between the mountains, all white, and a piece of steel skeleton was thrown away.

"Sister Xia. Look at this time machine, is it the one you used to ride at that time?"

Looking up at the huge goose egg, Su Yuan asked with emotion.

"Yes, this one! It is the time machine created by Daddy's entire Haizhou base!"

A faint crystal flashed across Xia Linfei's simple face, and Su Yuan looked at the goose egg silently. He couldn't help but feel a little confused: "Since it was the time machine that Sister Xia had taken, why did she go until 1993 and was picked up by her mother?"

"Sister Xia, you and Gao Jun, oh no, how many years did you and your father originally planned to travel through time?"

"I remember my father set it in 2006. After all, the disaster occurred in 2013. It is really unnecessary to travel too early. We have made an estimate that with the technological level at the beginning of two thousand years, we can achieve our goal with the ability to prepare six or seven years in advance."

"But my time machine was picked up by my mother in June 1993..."

"Then I don't know. I used it before I could urgently debug it after I built the time machine. Some accidents might have happened. When I woke up, it was already 2006, but my father and the time machine disappeared. I don't know if it was caused by an accident in the middle, or if my father deliberately left me in 2006."

"But it's unlikely that Dad will leave me halfway through... I think the biggest possibility is that an accident happened."

That's really a failed time travel!

Su Yuan knew it in his mind and said with a smile: "Didn't you say there is a record in it? Let's go in and take a look?"

Xia Linfei nodded and opened the hatch door of the time machine with Su Yuan and entered it.

Because the time machine has been turned upside down, when I got inside, I found that the inside was in chaos, and several metal pipes even had minor cracks.

"Huh!" When the two of them touched the driver's seat, Xia Linfei suddenly exclaimed in surprise.

"What's wrong?"

Su Yuan looked at her in confusion.

"How come there is a word 'Qi' here?"

Su Yuan looked closer and saw that Xia Linfei was talking about the position of the word "全" engraved on one of the twelve green buttons under the LED display.

"Oh, that's the start button of the time machine. If it weren't for this word, I wouldn't be able to run it." Su Yuan smiled.

Although the crooked word "Qi" looks ugly, it still helped her a lot at critical moments.

Xia Linfei frowned and frowned, saying, "I remember when I was manufacturing the time machine, my father deliberately did not write the button information on it. The word "Qi" was obviously not my father's hand."

Su Yuan was stunned for a moment, and then suddenly realized that Gao Jun's consideration was guarding against Weiran. You should know that the time machine is a real killer weapon. It is best to let others get it but not know what it is. Even if you know it, you don't know how to operate it. This is the best.

This is obviously the word "Qi" that was engraved afterwards. It appears on it, which looks inappropriate and very abnormal.

"Okay, okay, let's not talk about this, record, what about record?"

"You wait..."

Xia Linfei nodded slightly, and quickly operated the buttons with his fingers. After a while, the machine still stopped moving. Xia Linfei had to operate it again. Su Yuan asked strangely: "What's wrong?"

Charlene also showed a confused look on her face, "The machine... seems to be broken..."

"broken?"

"Um!"

"How could this happen? Could it be that it was broken when landing?" Thinking that he was shocked when he traveled to this world, the time machine rolled directly from the hillside to the bottom of the mountain, and even his "legs" were broken, Su Yuan couldn't help but feel a little embarrassed.

There is always a feeling of guilt that she has broken her time machine.

Xia Linfei looked up and saw the "12" displayed in the energy groove, and the expression on her face became more complicated. "Su Yuan, what is the number on this before you traveled through time?"

"It seems...36, well, it's 36! I used up 24 that time travel!"

"Are you sure?"

"Confirm, what's wrong?"

"I have read the design manual of the time machine. Theoretically, the energy used for traveling through time should be below 40. The energy we pre-installed for the time machine is sufficient. Even if it is carried out at the maximum power, it can travel at least twice more!"

"Ah, that's not right?"

How can the total energy of 100 be reduced to 36 after using it once? You should know that when you use it, you only use 24 of energy.

It seems that this time machine is indeed very strange! What’s hateful is that when it is urgent to figure out the key, the time machine is actually broken and the data it records cannot be seen!

"Sister Xia, can I fix it?" Su Yuan asked weakly.

"It's hard to say, it mainly depends on where it is broken. The time machine is a very complex machine. A little careless may cause overall damage. Moreover, it needs to enter a long river of time when it travels through time and space. Any component is damaged. It is fatal! If this time machine falls like this, it will definitely not be used anymore."

"And the recorder and the power core are all operated by the internal 'time ruler'. The time ruler is the easiest to damage among all components. On the premise that the time ruler cannot determine whether it has traveled through, the recorder will not trigger the recording function."

"Isn't it possible to even check the previous records?"

Xia Linfei nodded: "I just tested it. The external circuit can still run, but the inside of the time machine has been completely burned. It should be that the power core has not stopped running and was damaged by external forces, causing the energy inside the core to break through the time ruler and recorder..."
