Three days passed quickly.

And Su Fan also did his best to complete all the tasks in the small world.

At the teleportation altar of the system, as the light of teleportation lit up, a blackened figure, holding the blue heart of the world, stumbled out.

"Welcome back again!" said the old village chief, half-bent over, in a respectful tone.

"Uh-huh!"

Su Fan nodded casually, and hurriedly walked towards his residence in the system space.

His residence in the system space was originally a small house.

However, as he completed the restoration of the system again and again, this small house has also changed a lot.

From the original wooden hut, it has become three large tiled houses, one of these three large tiled houses is his own residence, and one is a treasure warehouse, and the other one he originally wanted to leave to Wu Ling'er.

It's just that Wu Ling'er doesn't know how to do it, since the system space has been updated to the Soul Emperor version, the black light cluster she has incarnated has been hanging high in the sky above the system village all day long, no matter how Su Fan communicates, the black light cluster just hasn't reacted at all.

Unable to communicate with Wu Ling'er, Su Fan simply left the tiled house idle, anyway, only he can enter and exit this system space, and it is the same whether there is anyone living in it.

"Hey, it's still comfortable to take a bath!"

At this time, Su Fan sat in the steaming bathtub, his eyes slightly closed, only to feel extremely comfortable up and down, and the color of his charred skin was slowly fading.

The reason why he looks like this has a lot to do with his trip to the small world.

The small world that Su Fan went to this time was called the Five Thunder Realm.

In the Five Thunder Realm, the weather is very peculiar, and there are nine hours of the day that are rainy and rainy, thunder and lightning.

The monks there were not the martial arts monks that Su Fan had known in the past, but the thunder spirits who practiced thunder and lightning spiritual arts.

These thunder spirits are extremely powerful in their spiritual power, and they cultivate by perceiving and absorbing the thunder and lightning elements between heaven and earth.

Although their physical bodies were weak, the attacks that erupted every time they cast a spell were as powerful as the martial arts released by ordinary martial arts monks.

This is the first time that Su Fan has come into contact with a cultivator from another world who cultivates spiritual power, and he is also an outlier in these five thunder realms, for those thunder spirit warriors.

Therefore, after Su Fan had just descended to the Five Thunder Realm, he was detected by a veteran Thunder Spirit Master with a strong spiritual perception.

And that Lei Lingshi actually had the idea of arresting Su Fan and doing a good study.

Of course, Su Fan was not happy about this, so the two of them fought.

Originally, Su Fan thought that with his powerful martial arts and divine sword intent, he should be able to easily wipe out the Thunder Spirit Warrior.

Who would have thought that by perceiving the thunder and lightning elements of heaven and earth, the thunder spirit man actually borrowed the thunder and lightning spirit technique to compete with Su Fan!

This surprised Su Fan, he had always thought that martial arts monks were stronger than spiritual path monks, but he didn't expect that spiritual path cultivation to the highest level would be on par with martial arts.

Even Su Fan felt that if the spiritual path cultivators could also cultivate martial arts, then the superposition of the two spiritual and martial arts, and the increase in combat power would definitely not be as simple as one plus one.

This discovery made Su Fan pleasantly surprised, and he thought to himself that if he could use the Spirit Dao to assist the Martial Dao, and attack the Spirit Martial Arts together with the enemy, he would definitely be able to make the enemy unguardable.

Su Fan has no shortage of exercises for cultivating spiritual power, and the Seven Stars refining method is.

However, although he has good exercises, he does not have enough experience to support them.

In terms of spiritual practice, Su Fan is still in the exploration stage.

If he could gain a lot of cultivation experience from the Thunder Spirit Warriors in this world in the next few days, then it would undoubtedly be the best harvest for him.

Therefore, Su Fan started the idea of fighting against him in front of him, and took advantage of the other party's unpreparedness to directly make a ruthless move, and repeatedly used the strongest hole card to kill the other party!

Afterwards, he even used the Soul Searching Secret Technique to read all the memories of Lei Lingshi before his death.

In this memory, with this Lei Lingshi's lifelong cultivation perception, after reading it carefully, Su Fan was greatly inspired, and some of the unsolved puzzles in his mind that he encountered when cultivating the Seven Stars Refining Technique also got perfect answers.

And just when Su Fan couldn't help but be overjoyed by his harvest, the other Five Thunder Realm spiritual powerhouses who sensed the death of this thunder spirit warrior rushed from all over the world.

The spiritual level of the Thunder Spirit Warrior in this world is equivalent to the peak level of the Soul Heaven Continent's third-grade soothsayers.

However, because they specialized in the spiritual level, their perception was more than a hundred times stronger than that of ordinary martial arts monks.

With such a powerful spiritual power perception, these Thunder Spirit Warriors quickly locked on to Su Fan's location and converged towards him.

Because the Lei Lingshi who was killed by Su Fan had a pivotal position in this world, after these Lei Lingshi who rushed to the scene arrived, they couldn't help but say anything, put all the blame on Su Fan's head, and launched the most fierce attack on Su Fan on the spot.

It just so happens that Su Fan himself is also a person who does not eat soft and hard, since he attacks him, then he is an enemy, and Su Fan will not show mercy to his enemies, and he will kill dozens of people in a short time.

At this moment, those thunder spirits were completely annoyed, and at the cost of sacrificing their lives, they unleashed a large-scale attack spirit array, condensing a cloud of extremely destructive black thunder.

Su Fan saw that they summoned thunder, and he was still happy at that time, he had to know that he was the ancestor of playing thunder, no matter how strong this black thunder was, could it still be stronger than his own heavenly thunder?

But the fact is that this black thunder is indeed outrageously strong, Rao is Su Fan's protective body with a heavenly thunder battle body, and he is also scorched on the outside and tender on the inside by this black thunder!

So, Su Fan became very interested in the source of this black thunder, and after resisting this black thunder, Su Fan checked all the memories of the thunder spirits through the soul searching technique, only to learn that the cause of this black thunder was nothing else, it was the heart of the world!

The heart of the world of these five thunder realms can actually transform ordinary thunder and lightning into black thunder with stronger destructive power, and if you want to communicate with the heart of this world, you must have extremely strong spiritual power!

Su Fan suddenly realized, no wonder he had always felt the strange energy contained in the heart of the world before, but he had never been able to mobilize and use this energy.

It turned out that it was not that the energy in the heart of the world could not be used, but that his mental strength and spiritual power control level were not enough.

After figuring out the ins and outs of everything, Su Fan quickly found the heart of the world.

However, since the people in the Five Thunder Realm have developed the method of using the World Heart, it is very difficult to capture the World Heart.

And the high-level Lei Lingshi here did not hesitate to sacrifice his life in order to protect the heart of the world. Summoned a cloud of black thunder, which turned Su Fan's dizziness.
