Su Yuan knew too little about Wei and Feng, and so far he didn't know anything except that he was Wei Hongye's elder brother.

The memory goes back to before fleeing to the Octagonal Jing Village, what role did Wei and Feng play in it?Su Yuan felt that there was a fog in front of her, and she wanted to break through it and connect the causes and consequences, but she couldn't see the road ahead.

Wei and Feng stood by the car door and exchanged something with the driver, and then walked towards the school gate with a bouquet of flowers. After he left, the man in the SUV put one hand on the window, took out a pack of cigarettes from his body, took out a cigarette and began to swallow the clouds.

The rearview mirror of the off-road vehicle clearly presents the facial expression of the rugged man, which is all seen by Su Yuan, and similarly, if he pays attention, he can also see Su Yuan in the white Audi TT behind. After realizing this, Su Yuan's body shrank down suddenly, and after a while, she carefully revealed her sunglasses-wearing eyes, and through the rearview mirror, she saw the rugged man lowered his seat, lying in the driver's seat and smoking comfortably.

"Judging from the man's performance, he seems to be a lot more casual after Wei Hefeng left, could it be that he is under pressure in front of Wei Hefeng?" Su Yuan thought incredulously.

Could it be that Wei and Feng are the superiors of rugged men?

What did Nawei and Kaede do? Judging from the fact that he could talk to the army, his identity should be innocent, and it is very likely that he and the rugged man were subordinate to the government's hands.

But what are they doing now, it looks like they are on a mission, but Wei Hefeng is obviously holding the bouquet of flowers in his hand to "chase" himself, in other words, their mission is related to himself, or is it deliberately approaching him with some purpose?

Suddenly. Su Yuan suddenly broke out in a cold sweat, could it be before the US special operations team attacked the base. Yourself and others have already entered the sight of the state?

Su Yuan thought about it, and the only possibility seemed to be because of the Internet storm. Could it be that they showed the horse's feet when they were not looking, and these horse's feet were discovered by the people of the state?

No, it shouldn't be like this!

Su Yuan quickly denied this speculation, Gaia's ability is very strong, and if he hadn't made a mistake in bringing Eve in, and then triggered a series of subsequent events, the U.S. government would not have been able to trace the source back to it. So the Chinese government has the ability to trace it to its own head? This concept is quite low, but it cannot be completely ruled out, so Su Yuan can only put a question mark on it.

"It seems that Wei and Feng should be a little more careful with this. Maybe he's the legendary Chinese agent. Su Yuan didn't care about eating the remaining half of the bread, his fingers lightly started the car, ran to a few hundred meters away from the off-road vehicle, and observed from a distance.

In about twenty minutes, Wei and Feng walked out of the school, the off-road vehicle started slowly, and Su Yuan didn't dare to be careless and hurriedly started the car and followed. Because he was afraid of the other party's unknown identity, Su Yuan didn't dare to follow too much. The distance between the two cars was 100 meters, sometimes up to 200 meters, and she almost lost it because of the traffic lights when passing through a few forks. Fortunately, the most rearly accelerated to catch up.

Just followed all the way, and after about half an hour, Su Yuan saw the off-road vehicle drive into a yard.

It is a courtyard with two high floors. In the heart of Riverside City, such high-rise buildings can be found everywhere. There's nothing to say about the building itself. As the off-road vehicle drove in, the fence gate at the gate of the yard slowly closed. Su Yuan couldn't follow up, so he had to park the car on a small road on the side.

After getting out of the car, she paced towards the place where the off-road vehicle drove in, passing a striking building along the way, which was the traffic police bureau under the Binhe City Public Security Bureau, and two steps further, she was stunned to find that the yard where the off-road vehicle drove into, and the sign "Binhe City National Security Bureau" was hung at the door.

Adjacent to the traffic police station turned out to be the State Security Bureau! Wei Hefeng's car drove here? She was startled, thinking that it was fortunate that she didn't follow up just now, otherwise there would definitely be no good fruit to eat.

"This Wei and Feng are really abnormal, they are actually agents of the National Security Bureau!"

This result was both expected and unexpected.

Although there is no legendary "murder license", the intelligence system department always has a lot of secrets that cannot be known to outsiders, and if they are accidentally charged with stealing secrets, they have no place to cry.

Su Yuan felt that it was not appropriate to stay here for a long time, so he quickly returned to the car. After all, there was something to be gained from this tracking, at least to figure out the identities of Wei and Feng, but Su Yuan was still confused about his purpose of approaching him.

When I looked at the time on the car, it was already a quarter past twelve.

"I almost forgot to get down to business!"

She quickly reacted, stepped on the accelerator, and headed in the direction of the base.

————————————

Base.

After Su Yuan parked the car, she quietly slipped outside the No. 3 laboratory, this time she came prepared, took out the eavesdropping device and periscope prepared in advance from her bag, skillfully put the headphones on her head, sat on the ground against the wall, and stared at the screen with her eyes unmoving.

She saw that in the No. 3 laboratory, Su Mengyuan was holding a 30 cm long, 10 cm wide, and 15 cm high machine with an LED display.

"This is the World Boundary Olfactory you made?" Su Mengyuan's voice sounded in the headphones, although the volume was a little light, but the sound quality was not bad, and there was not much interference.

Soon, Su Yuan heard Gao Jun's answer again: "Yes, this is a simplified version made by me and Lin Fei based on the extracted techniques, and since many materials cannot be found, we can only do this step." ”

"Can this work?" Su Mengyuan played with the Shilu Boundary Sniffer.

"Of course it works! Hey, you tap, don't break it. ”

"Su Yuan, return the things to Gao Jun and let him show us. This was Ji Ye Hao's voice, and at the same time, Su Yuan saw Ji Ye Hao come forward and pat Su Mengyuan on the shoulder.

"Na, give!" Su Mengyuan said and handed the Shilu Boundary Sniffer back into Gao Jun's hand, and then Su Yuan saw from the screen that Gao Jun buckled a plate on the back of the machine and began to put batteries into it.

With Gao Jun's actions, Su Yuan's heart also suddenly lifted, "You can see the value of the World Boundary Boundary immediately, I don't know how many ...... this World Boundary Olfactory in his hand will display."

Su Yuan's breathing became rapid, and his eyes didn't dare to blink at all, as if he was afraid that the value would jump because of blinking.

As Gao Jun pressed the switch button of the Shilu Boundary Sniffer, he saw that the seven display units on the LED digital display lit up together, and then began to beat, and Su Yuan, who was peeping, also held his breath at this time.

After about half a minute, the number finally froze and it showed "0.899210"!

"What does this mean?" Su Mengyuan's puzzled voice sounded in the earphones.

Charlene replied, "...... Our world corresponds to a unique world boundary value, and the symbol α represents the world boundary, then our world is the world world boundary α=0.899210. ”

......Seeing this unfamiliar number, Su Yuan let out a long breath, and the whole person seemed to have been drained of strength, and he leaned against the wall very tired. The cold chill on the surface penetrated the light jeans and reached Su Yuan's buttocks, and it didn't take long for it to turn into a biting chill.

Su Yuan didn't care, she was already completely immersed in the values presented by the Shilu Boundary Olfactory Sensor.

It's different, it's really different, she repeated this thought in her mind, the value of the world and the world is different, that is to say, the world and the world line where she is currently has a completely different future from her memory. This is exactly what she was expecting, showing that ...... She does have a chance to change the future!

In the next No. 3 laboratory, Su Mengyuan and others dropped the jade for safety reasons, for these side matters Su Yuan felt that there was no need to observe, and returned to the car, she finally calmed down from the chaotic and agitated thoughts, and with a frown, she picked up the record book and the pen she carried with her, and began to think.

"I have gone through several rounds of [backtracking], a total of α1=0.800120, α2=0.800110, α3=0.800090, α4=0.800030, and later α5=0.8000020, α6=0.8000013, α7=0.8000002, and when α8=0.7999920, I used a time machine to jump to the current α=0.899210 world. ”

"Among them, α1, α2, α3, and α4 are experienced in the first round of [backtracking] in order to successfully escape from the 'base', and α5, α6, α7, and α8 are experienced in the second round of [backtracking] in order to leave Panzhou County. Eight world and seven jumps, all of which are [backtracking], and judging from the value of the world and the world, the value of each jump is decreasing, is it really as Ji Ye Hao said, [backtracking] will bring bad results?"

[Backtracking] can change the local "unfavorable situation", but from the overall point of view, the good and bad of [Backtracking] is still unknown, Su Yuan was thinking after experiencing the spatial crack, could it be that when the value of the World Lu boundary line reaches zero, it is the time when the entire World Lu Realm is completely annihilated?

If this guess is followed, then [Backtracking] really needs to be used with caution, at least until she finds the answer that every time [Backtracking] is Wei, the value of the World Boundary will be lowered, she can't use it indiscriminately.

"Is it because the ability of [backtracking] is not enough to go back to a longer point in time, so the positive impact of [backtracking] is weaker than the negative impact?

Su Yuan didn't know if her thoughts were right, and if she wanted to test her guess, she had to verify it once, but she finally used the time machine to increase the value of the world line so much, she didn't want to let the world line move closer to the direction of α1!

The closer the value of the world boundary, the more similar it is in the future, and α=0.899210 is not easy to deviate so far from the original world boundary, it may have jumped out of the cycle of "tightening". (To be continued......)
