Su Yuan and the others only stayed in the study for half an hour, and then came out of the room, politely refused Zhou Wan's invitation to stay for dinner, and left in a hurry.

Come and go quickly, after Su Yuan and the others left, Zhou Wan nagged at Gao Xiang: "What the hell is going on, the two children still have something to do with you, a big scientist? Seeing that they are so anxious, they don't even have the heart to eat a meal!"

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

Zhou Wan couldn't help laughing, and said with anticipation: "Look at the girl who was with Xiaoyuan just now, does she have any hope of being our daughter-in-law?"

"I don't know if she has any hope, the key depends on whether Xiao Junnu doesn't work hard! However, you must be wrong about one thing, it wasn't Xiao Yuan who came over just now, it was Xiao Yuan's 'sister' Xiao Mei!"

"Is it Cai Wei's daughter who just got back?" asked Zhou Wan incredulously.

Seeing Zhou Wan's shocked expression, the corners of Gao Xiang's mouth raised slightly, "Didn't you see her at the engagement banquet and didn't recognize her?"

Zhou Wan nodded and said in surprise: "She came with that Charlene, I thought it was Xiao Yuan." ”

Out of Zhongxing Garden, Su Yuan and Charlene sat on the white Audi TT and drove slowly along the trail. This time, I made a special trip to find Gao Xiang, but I didn't get much gain. However, they still got some information from Gao Xiang's mouth, and basically determined the reason for the lack of thirteen hours on September 5, which may have happened in the inner solar system.

"Sister Xia, will this partial time lapse cause a change in the value of the world line?" Su Yuan suddenly asked as he drove the car.

This question does not seem to make much sense at first glance, but in fact it deals with the essence of the world line.

Charlene thought for a moment. Answer: "It stands to reason that even the smallest time goes back." will cause substantial local historical changes, and the world line value is a physical quantity that represents the whole world. Local changes are also a small part of the whole, so they should also 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, but in the huge sea of stars, it is just a very small droplet. The solar system has gone back in time, and the absolute value of the worldline value must have changed, but it may not be clearly displayed on the worldline olfactory. ”

Su Yuan understood. Speaking of which, the sensitivity of the world-line olfactory is not enough, and the reverse flow on September 5 is not like the subsequent crossings, which is a space-time change in the entire universe. It is confined to a single solar system and has an extremely limited range of influence, with a total of seven figures in the worldline olfactory that cannot exhibit such a trivial change.

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

The car drove on the road, and the cabin was quiet. After a moment of silence, Xia Linfang suddenly said, "Su Yuan, take me to see the time machine you are on." ”

Su Yuan concentrated on the steering wheel. Hearing this, he said unexpectedly: "That one is halfway up the mountain." ”

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

"There shouldn't be a second time machine in this world. If I'm not mistaken, the time machine that brought you to this era is probably the one I rode in the first place! I remember that the time machine had a recording function, and it could record the worldline data after crossing in the first time. Is it the same time machine? See for yourself. ”

"I see!"

The two no longer hesitated, taking advantage of the fact that it was still early. Su Yuan and Xia Linfeng went directly in the direction of Phoenix Mountain.

I parked the car at the door of Lao Liu's house in Xiaoqiao Village, at the foot of the mountain that helped Su Yuan last time, and bought some dry food by the way. The two of them went up the mountain in the dust. They walked along the foothills, and after half a day of climbing, they finally reached the place where the time machine was staying before dark.

The site has been maintained with a shed, and there are people arranged by Su Caiwei not far away to guard it at all times. When the staff saw Su Yuan, because they had received Su Caiwei's notice early, the on-site personnel did not come forward to stop them, and let the two go straight into the shed.

The huge metal ball was lying in the depression between the mountains, milky white and chubby, occupying the entire field of vision at a glance, and the majestic momentum was coming, and the fly in the ointment was that one of the steel skeletons was thrown out of the distance.

"Sister Xia, do you see if this time machine is the one you rode in at that time?"

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

"Yes, it's this one! It's a time machine built by Dad at the entire Haizhou base!"

A faint sparkle flashed on Xia Lin's elegant face, Su Yuan looked at the goose egg silently, and couldn't help but have a trace of doubt in his heart: "Since it is the time machine that Sister Xia has ridden, why did she go to 1993 and be picked up by my mother?"

"Sister Xia, you and Gao Jun, oh no, you and your father originally planned to travel to a few years?"

"I remember that my father set the year 2006, after all, the time of the disaster was 2013, and it was really unnecessary to travel too early, and we made an estimate that with the level of technology at the beginning of the 20000s, it was possible to achieve the goal by preparing six or seven years in advance. ”

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

"Then I don't know, after the time machine was built, it was used before it had time to be debugged, and there may have been some accidents in it. When I woke up, it was 2006, and my dad and the time machine were gone. I don't know if it was an accident or if my dad deliberately left me in 2006. ”

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

It's a failed crossing!

Su Yuan knew it in his heart, so he said with a smile: "Didn't you say that there is a record in it?

Charlene nodded, and together with Su Yuan, she opened the hatch of the time machine and entered inside.

Because the time machine has been reversed, when you get inside, you find that there is chaos inside, and several metal pipes have even cracked slightly.

"Huh!" When the two touched the driver's seat, Charlene suddenly exclaimed.

"What's wrong?"

Su Yuan looked at her puzzled.

"How can there be a 'Qi' word here?"

Su Yuan took a closer look, only to see that Xia Lin was talking about the position of the word "Qi" engraved on one of the twelve green buttons under the LED display.

"Oh, that's the start button of the time machine, and if it weren't for that, I wouldn't have been able to do it at the time. Su Yuan said with a smile.

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

Xia Lin frowned and frowned: "I remember that when I made the time machine, my father deliberately didn't write down the key information, and the word 'Qi' was obviously not my father's handwriting. ”

Su Yuan was stunned for a moment, and then suddenly realized, Gao Jun's consideration can be said to be precautionary, you must know that the time machine is a real killer, it is best to let others get it and don't know what it is, even if you know, you don't know how to operate, so it's the best.

This is obviously engraved after the fact of the word "Qi", appearing on it, it looks nondescript and very abnormal.

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

"You wait......"

Xia Linfeng nodded slightly, and the ten fingers quickly operated on the buttons, and after a while, the machine still did not move, and Xia Linfeng had to operate it again, Su Yuan asked strangely, "What's wrong?"

Charlene also showed a blank look on her face, "Machine...... It seems to be broken......"

"Broken?"

"Hmm!"

"How could this be, could it be that it was broken when I landed?" Thinking that he was shocked when he crossed into this world, the time machine rolled directly from the hillside to the bottom of the mountain, and even the "legs" were broken, Su Yuan couldn't help but be a little surprised.

There is always a sense of time machine that has been broken by her.

Charlene looked sideways, and saw the "12" displayed at the energy gauge, and the expression on her face became more complicated. "Su Yuan, what is the number on this before you cross?"

"It seems to be...... 36, well, it's 36! I used up 24 for that crossing!"

"Are you sure?"

"Are you sure, what's wrong?"

"I've read the design report of the time machine, theoretically the energy used for a time trip should be less than 40, and the energy we pre-installed for the time machine is sufficient, even if it is carried out according to the maximum power, it can be at least two or more times!"

"Ah, isn't that right?"

How is it possible to use a total of 100 energy and then reduce it to 36 after using it once? You must know that when you use it, you only use 24 energy.

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

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

"It's hard to say, mainly depending on what is bad about it, the time machine is a very complex machine, and the slightest carelessness can cause overall damage. Moreover, it needs to enter the long river of time when it travels through time and space, and any component damage is fatal! This time machine is broken like this, and it must be unusable. ”

"And the recorder and the power core are based on the internal 'time gauge' to operate, the time gauge is the most vulnerable to damage of all components, and the recorder will not trigger the recording function under the premise that the time gauge cannot determine whether it has been crossed. ”

"Can't even look at previous records?"

Charlene nodded: "I tested it just now, the external circuit can still run, but the inside of the time machine has been completely burned out, it should be that the power core has not stopped running and has been damaged by external forces, causing the energy inside the core to penetrate the time ruler and recorder ......"
