Chu Nan simply felt that there was no one left.

I won't talk about the charging refining method before.

After all, the electricity charged is also electricity, and it is not fundamentally different from the thunder and lightning in nature.

But now, just in the sea of knowledge, I used my spiritual power to visualize a bridge, and what the hell did it have to conform to the principles of mechanics.

It's hilarious.

Although he could be sure that there was no problem with this set of exercises, it would not be too much of a problem if he cultivated like this directly.

However, the system had already pointed out its flaws, so how could he be willing to practice such exercises directly.

He must find a way to make up for such shortcomings.

But the point is, the system did not give him a solution.

What's even more ridiculous is that the reason is that there is no relevant information in his memory, and the system cannot perfect the Xianggong method for him.

That's just a pitfall.

Do you want him to learn the mechanics of bridge design?

Chu Nan was a little speechless.

I had to familiarize myself with the method of visualization, and when I saw that the time was almost up, I quit visualization.

He has to go to class, so it doesn't matter if he's late for self-study, but he can't be late for normal class.

After all, exams are about system upgrades.

......

As soon as Chu Nan walked into the classroom, he found that everyone was staring at him with a bright face.

What a situation is this?

"Brother, you are too cruel, you are my brother......"

Before he could react, a group of boys had already surrounded him.

"You are simply a role model for everyone!"

"That's it, brother, when will you teach the brothers two tricks!"

"We don't support the wall, so we will obey your ......"

Chu Nan felt a little inexplicable, pointed to his nose, and said with some disbelief:

"Are you talking about me? I don't understand!"

"Boss, brother, let's call you brother, don't be so modest!" a group of people coaxed.

Wang Liang walked over from behind the crowd at this time and said with a deep face:

"Dude, this is not right, for the sake of everyone's classmates, you can start with the real move!"

"What can't be recruited...... Chu Nan felt even more inexplicable:

"You all make it clear to me!"

"You really don't know?" a group of people stared at him as if they were aliens.

"I don't know!"

"Oh my God!" Wang Liang pushed his flat glasses for the sake of the bag, and sighed to the sky:

"God, why don't you send a bolt of lightning and chop this animal to death......"

Bang!

Just when everyone was a little commotioned, two thunderbolts exploded in the sky.

Nima, what's going on?

Wang Liang looked confused.

The others, looking at the two lightning bolts in the sky, were also confused.

It's still spring.

At this time, it is usually a little rain, especially when the sky is still clear outside, how can there be sudden thunder.

"Well, you don't really think that God is going to take this demon away!"

Seeing that everyone was a little stunned, Wang Liang couldn't help but hurriedly laugh and scold to ease everyone's embarrassment.

When he saw Chu Nan also looking nervous, he couldn't help but smile and said:

"Virgin, don't worry, this is probably going to rain, it's a natural phenomenon, it's a natural ......"

Boom, boom......

His words fell, and two thunderbolts rang out again in the sky.

What made everyone even more frightened was that a lightning bolt actually flashed from the sky and slashed towards the teaching building.

Although when approaching the lesson building, it was led away by the lightning rod on the roof of the building.

However, everyone could clearly see that the thunder was coming in the direction of Chu Nan.

No one dared to speak.

Only Wang Liang quietly pulled Chu Nan's clothes and whispered: "Chu Nan, you can't really do anything hurtful!"

"You are the one who hurts the heavens and harms the reason, and your existence in the world is the biggest harm to the heavens and reason......"

Chu Nan replied angrily.

At this time, he also reacted.

It's not thunder at all.

Rather, someone has crossed the catastrophe......

Yes, it's the one who crossed the catastrophe.

Originally, he hadn't noticed it, but at this moment, he suddenly woke up.

Today, the concentration of Heaven and Earth Yuan Force outside seems to be a little thicker than yesterday?

Although he didn't know what was going on, in his opinion, it should be related to the Tianxuan Continent.

In the original book, although it will take a few years for someone to come to Earth from that spatial rift, this does not mean that this spatial rift will not appear until a few years later.

Now, if there is a spatial rift, it has appeared.

From the Tianxuan Continent, some Heaven and Earth Yuan Power leaked over, which seemed to make sense.

Moreover, this kind of Yuan Force leakage should not be a day or two.

With this wind direction, it is normal for someone to break through the previous bottleneck.

Although the earth is in the era of the end of the law, since there is a cultivator like Xia Xue, it means that the inheritance on the earth has not been completely broken.

For example, Xia Xue, who suddenly broke through from the first level of true qi to the second level of true qi overnight, may be the beneficiary of this shareholder wind.

For another example, Xu Youlong before, the 'City Soldier King', also inexplicably broke through to the dark energy.

Chu Nan looked at the scene in front of him, and he still didn't understand.

This is clearly someone who took this opportunity to rush to the innate realm.

When the innate powerhouse breaks through, he will frantically absorb the Yuan Force that escapes between heaven and earth.

And these yuan forces will naturally not be completely absorbed by the innate powerhouse.

When the innate powerhouse breaks through, these heaven and earth yuan forces will be scattered in the air again.

These elemental forces, in the process of absorption and dispersion, can easily form a vortex of elemental forces.

If we use a simple analogy, these elemental forces are likened to charged charges.

When the charge reaches a certain level, lightning is triggered.

And after the cultivator breaks through, the strong Heaven and Earth Yuan Force will trigger the 'Heavenly Tribulation'.

And the cultivator's biological magnetic field is too strong, as soon as these 'Heavenly Tribulations' are born, they will naturally target the creatures with strong magnetic fields.

Therefore, it is too normal for Chu Nan to be struck by lightning in someone else's place of tribulation.

However, what puzzled Chu Nan was, who would be in the catastrophe?

This thunderbolt was taken away by him, and most likely he was going to succeed.

But even before the tribulation, in Xia Xue's description, he was also a grandmaster-level figure.

How could you run here inexplicably and survive a catastrophe......

......

"Tell me, what's going on?"

Chu Nan stared at Wang Liang angrily, it was obvious that this guy was spreading rumors.

"You really don't know?"

At this time, everyone also reacted, and they all returned to their seats, Wang Liangyou looked at the scattered crowd with a smile, and couldn't help but say a little embarrassed: "I thought you knew!"

Seeing that Chu Nan didn't know why at all, he couldn't help but whisper: "The one from your family, the eldest *aunt* is here!"

Burst!

Chu Nan almost sprayed him in the face, "What did you say?"

How could he know about this kind of thing, and it seemed to be known to everyone in the class.

"It's her aunt and aunt who are here!" Wang Liang said seriously.

Chu Nan stabbed him with a pen and said, "Why don't you say that the eldest uncle is here!"

Unexpectedly, Wang Liang actually looked suddenly enlightened: "By the way, it seems that her eldest uncle is also here!"

Seeing Chu Nan's puzzled look, he couldn't help but explain, "We all thought that people came to see you on behalf of their parents!"

Burst!

Chu Nan understood, it was a real relative who came.

I was also misunderstood by everyone to meet my parents.

However, this Nima is too pitiful.

What kind of relatives are not good, it is actually her aunt, and she is the boss!

It's no wonder that everyone can only understand it, but it can't be spoken.

"But that's not right!"

Chu Nan suddenly reacted: "How do you know about this matter?"

"Because, this morning, someone came to the school, and after being stopped by the doorman, she claimed to be Xia Xue's aunt, and she was going to find a guy from Chu Nan!"

Burst!

Chu Nan felt that he was about to vomit blood and die.

What kind of superb relative this is!

However, he just smiled and didn't take it too seriously.

The world is so big, there are all kinds of people.

If people want to look for him, he is not afraid.

Originally, everyone used it as a false rumor, and nothing really happened, what was he afraid of!

......

At this time, his main goal was to take exams and ...... And take the time to look at the mechanics of bridges.

The pit forcing system, I don't know if it can be directly deduced with experience points.

He has already decided that after the exam, he will go to the cross-river bridge in S City to have a look.

That bridge, although it is not famous in China, is a modern bridge.

Anyway, it should also conform to some mechanical principles.

He has understood that as long as he has the system, the knowledge he has learned or seen, will be improved into the system's database.

And if he can pass the exam, it means that this knowledge has been mastered, and the knowledge that has been mastered will be fed back to him in the form of experience points.

"Stand up, hello teacher!"

"Hello students!"

When they saw Teacher Mo Xiaoyu walk into the classroom, everyone knew that there was another exam.

In the third year of high school, there is a big test in three days and a small test in two days, which is by no means a joke.

But what made Chu Nan depressed was that he found that a lot of the content here was actually taken last time.

Although he didn't confirm it, he had an intuition that even if he answered the content of this kind of test correctly, he wouldn't give him any more experience.

In order to verify the conjecture, he handed in the paper early.

However, he did not leave the classroom.

Instead, pick up a book and pretend to review it......

Sure enough, it didn't take long for his exam paper to be corrected.

When he saw that the test paper had been corrected, he left the classroom directly, and as he left, he glanced at it.

142 points.

A score that is by no means low.

However, he only gained less than 80 experience points in his system.

It was exactly the same as his own guess.

A small part of it was just examined, and he didn't gain even a little experience.

"You did well in the exam this time, don't be proud, make persistent efforts next time and strive to do better......"

Seeing Chu Nan leaving, Mo Xiaoyu did not hesitate to praise him.

This kind of honor student, which teacher doesn't want it.

Seeing Chu Nan being praised by the teacher, a group of people in the class were almost out of breath.

Especially a group of boys, how to look at it and how unhappy.

In everyone's opinion, Chu Nan was obviously waiting for the results to come out before deliberately leaving, the purpose was naturally to let the teacher praise him......

Just when everyone was secretly unhappy, Chu Nan seemed to be a little embarrassed and said:

"Teacher Mo, this exam is too easy, next time, can you take the difficult test!"

"Poof......
