When Riley and Tucker finished their training, a hint of joy flashed in their eyes. Before they had time to savor the feeling of the training just now, they saw what Rhett was doing at this moment and were all shocked.

"Father, are you practicing breathing techniques?"

Ruilai's pupils shrank slightly, and then he suddenly realized, yes, who stipulated that breathing and meditation cannot be practiced at the same time? It's just that in reality, there are very few people with excellent talents in both. Even if there are, no one will waste energy on the two extraordinary systems.

After all, the stronger the strength, the longer the life span, which is enough to attract people to specialize in one. And even if a level 2 dual-cultivation extraordinary is born, he is still no match for a level 3 extraordinary, so smart people will choose to cultivate only one system, and over time it has become a consensus across the continent.

"That's right, you should practice the breathing method quickly, there will be other surprises waiting for you later!" Rhett said breathlessly, his whole body was dripping with sweat, directly dripping onto the ground beneath his feet.

"Oh, okay!" Tucker shook his head, quickly came to his senses, and began to teach Yu Ruilai the content of the breathing method.

Soon, on the open space, the father and his two sons tacitly practiced the same breathing method and made strange and twisted postures.

As time passed, the gray fog around them also silently penetrated into their bodies, strengthening the bodies of the three people.

After about dozens of minutes, the father and his two sons stopped practicing one after another.

Each of their figures and physiques were in sharp contrast to what they had just seen. Their muscle lines were particularly obvious, their heights and arm spans were more slender, and their energy and spirit seemed more abundant.

"Wow, this is so cool. I have never had such an experience in my life. In such a short time, I am enjoying the rapid training speed!"

Tucker said with a laugh as he stretched his body.

Ruilai also twisted his neck and looked at his body happily, but a trace of confusion gradually appeared in his eyes, "Huh? Why can't I feel the existence of elements? I originally thought it was because of insufficient mental strength. Now it seems that the elements in the world are extremely thin..."

"You're right, even the fighting spirit has no elemental attributes!" Tucker came back to his senses, his smile faded, and he noticed this abnormality. He closed his eyes and carefully experienced it, and said: "But through practicing breathing techniques and developing the potential of the physical body, a kind of fighting spirit without attributes is still born. It's really interesting."

Rhett was used to this, but suddenly, he looked at Tucker, seemed to think of something, and said quickly:

"Tucker, you were a knight before and you have mastered many fighting skills. Try to use them here."

Although the presence of gray fog all around can greatly speed up the speed of cultivation, it is of no help in practicing fighting skills. After all, practicing fighting skills requires hard work and understanding, not the enhancement of physical and mental strength.

Lei Te had already tried it in the last simulation. People without basic skills simply cannot master it in a short period of time.

But this time, the situation was different when he brought Tucker with him. He really wanted to see what it would be like when this kind of attributeless fighting spirit was used to perform fighting skills.

Tucker nodded quickly after hearing this, bent his waist and knees, gathered his strength, swung his palm like a knife, and shouted with all his strength:

“Flame Slash!”

There was a whoosh sound, followed by a series of sonic booms in the air, and a pure white airflow condensed in Tucker's hands, forming a half-moon arc when it chopped down from top to bottom.

It rushed into the gray fog swiftly, and flew more than ten meters before slowly dissipating...

Feeling the power of this blow, Rhett and Riley were moved.

Although it lacks the burning power of the Flame Slash performed by the fire-based Dou Qi with the fire element added, the pure striking force is also extraordinary and is definitely much stronger than physical punches and kicks.

Tucker put away his posture, his face returned to normal, and he grinned and said, "It seems to be quite effective. This pure fighting spirit is quite interesting. It feels a little different from the fire fighting spirit, but it's hard to say where the difference is."

"Not bad." Leiter clapped his hands, nodded approvingly, and said, "Try the Phantom Recall again."

"Okay!" Tucker turned around and ran towards another deserted place, his feet making a thudding sound on the ground.

A second later, Tucker, who had run more than ten meters, was lit up with white fighting spirit light. It was extremely dazzling, as if it could pierce through the gray fog around him.

The next moment, almost as if by teleportation, Tucker, who had already run far away, returned to the starting point in a trajectory that was difficult to see with the naked eye.

A strong wind blew, making Rhett and Riley's hair flutter.

Tucker turned and smiled at his father, "When performing Phantom Recall, I feel that there is not much difference between using attributeless fighting spirit and using fire fighting spirit. It may be that when performing attack-type fighting skills, the power will be weakened to varying degrees."

"I see, interesting..." Rhett touched his chin and fell into thought.

Suddenly, two spots of light, one large and one small, one bright and one dark, appeared in front of us.

Tucker was horrified, pointed to the sky and shouted: "Father, look, something is coming!"

Ruilai looked in the direction of the finger with a nervous expression, but when he saw a light red light, his expression moved slightly and then gradually relaxed, as if he had guessed something.

"Don't be nervous, Tucker, we are one of us." Rhett patted Tucker on the shoulder, looked up, and a hint of joy appeared on his face.

"One of our own?" Tucker was stunned for a moment, then suddenly realized: "I understand, it's Grandpa Manu."

The light approached quickly, and it turned out to be Manu and Minge.

After smiling and saying hello a few times, Manu looked at Lei Te and said, "The source of fire is coming soon."

Lei Te's eyes lit up, "That's great, then I'll ask you to drive them here later..."

"Haha, it's a small matter." Manu smiled and said, "I came here to tell you something else. Regarding Mingge, it seems that it can't practice meditation. When I took it to observe the world barrier just now, it couldn't operate smoothly no matter what."

"Oh?" Rhett looked at Mingge in surprise. The latter didn't dare to look directly into Rhett's eyes. He lowered his head in disappointment and didn't dare to say a word.

"Maybe its composition is somewhat special. The soul level is different from that of humans, and meditation is exclusive to the native world. It is a shortcut to transcendence. It is normal that alien species cannot practice it." At this time, Ruilai said thoughtfully.

Manu looked at Ruilai with a gleam in his eyes, and said with satisfaction: "Very good analysis, I also think this is probably the reason!"

Riley smiled shyly, "Thanks for the compliment."

"In that case, let it try to devour the flames later. It should be able to absorb the essence of fire." Rhett waved his hand.

"No problem, let's go over first." Manu said, turning around and about to leave.

"Wait, I have something to ask you." Lei Te waved his hand and asked, "When you came here just now, did you find where the third-level female knight was?"

Lei Te narrowed his eyes and said, "I understand. Then you can go up quickly."

Manu nodded, then quickly left with Mingge.

"Father, what is a third-level female knight? Are there other awake humans here? But now is the beginning of creation, how did they train to become a third-level knight?"

Ruilai waited for Manu to leave before he expressed his doubts.

Tucker also came back to his senses, "Yes, since it was the beginning of creation, how did others obtain the breathing method? Also, you didn't answer us just now, where did humans come from at the beginning of creation?"

The two looked at their father with curious eyes and were particularly curious about the origin of the world and the origin of mankind.

Facing the children's passionate gazes, Lei Te smiled gently and said:

"I can't answer this either, because the birth of our world and the origin of mankind are all mysteries."

"We discovered in our last simulation that in the distant void outside this world, there is another world that is countless times larger than ours."

"That world is vast and mysterious. If nothing unexpected happens, our world also came from there. Similarly, all humans in this world also come from...that world!"

At the end of his words, Leiter pointed to a certain direction, which was the location of the big world in his memory.

Ruilai turned his head and looked in the direction of the finger. He was shocked, as if his sight had penetrated the gray fog and saw the mysterious world there! "Incredible, it turns out that we are not here at all?" Ruilai murmured to himself.

"Doesn't that mean that it is possible that humans jumped down from the trees?" Tucker was stunned and said subconsciously.

With a slap, a slap landed.

Tucker cried out in pain, covering his head, and looked at Rhett's big hand aggrievedly, "Father, why did you hit me again? I was just joking..."

Leiter glanced at Tucker and ignored him, saying to himself, "Our world is actually always drifting in the void. Who will attract us, what will attract us, where we come from, and where we are going? Everything is a mystery."

"You may encounter danger, but you may also encounter opportunities. Fortunately, we came from a safe and sound future. We know that before this, opportunities must have far outweighed dangers. We may even have missed a lot of opportunities in the world."

"The purpose of our coming here is to seize all those missed opportunities!"

Ruilai looked dazed. After quickly sorting out all the information in his mind, he gradually came to his senses and sighed. Then he asked, "Could the flowing fire just now be a kind of 'opportunity'?"

"That's right." Rhett looked at Tucker and said meaningfully, "It was because of the missed opportunity that the fire-type extraordinary people in the world were able to gain a lot in the fiery mystery..."

Tucker scratched his head. "It turned out to be the work of my father. I was wondering how I suddenly realized the mystery when I was executing the orcs at the execution ground that day... Hehe, thank you, father!"

Ruilai's eyes gradually became hot, "If that's the case, doesn't it mean that I may also be able to comprehend the mysteries of the water system? Father, when can we encounter the origin of water?"

"That's hard to say." Leiter laughed and shook his head, "But it's certain that we will encounter it sooner or later, and when the origin of the world is added, it is also the moment when the overflow evolution is most obvious. All the extraordinary people who survive in the world will easily understand the mystery."

"I see..." Tucker nodded suddenly, understanding why he could easily comprehend the mystery.

Ruilai was a little regretful, "It seems that I will not be able to experience the mystery this time."

"That may not be the case!"

Manu's laughter came from the sky.

Ruilai woke up with a start and looked up, only to see a large ball of fiery red light gradually moving towards the ground under the drive of Manu and the transparent bat.

Tucker's eyes widened and he exclaimed, "What a huge ball of fire element!"

"Eh? It doesn't seem to be the case, but it gives me a familiar feeling..."

"Oh yes, I remember now, it's Blazing Mystery, that ball of flowing fire is Blazing Mystery!"

"It looks like it is gradually dissipating and blending into the world. It seems that this substance cannot exist in the world for long!" Ruilai narrowed his eyes and quickly stated his observations.

"It is also possible that the world is actively absorbing. The world is not a dead thing. It may just lack human consciousness." Rhett said softly.

Ruilai's eyes flickered, and he nodded slightly, "That makes sense..."

After about a few seconds, the flowing fire was driven closer and closer, and when it reached the ground, it had dissipated a little again.

But the remaining fire essence is enough for these people to absorb.

In the last simulation at the beginning of the creation, Rhett, Thales and Manu did not waste a minute, but they only absorbed a small part before the fire dissipated.

"Is this the origin of fire? How magical..."

Ruilai looked at the ball of fire, but when he used his mental power to feel it, he found that it contained extremely profound mysterious laws, as if it could burn everything in the world and shock people's minds!

"Don't waste time, kids, just absorb it!"

"Remember to use your mental strength to try to merge them, and only absorb the scattered light points each time, otherwise your soul will not be able to bear the pain of direct absorption!"

Leiter took a deep breath, quickly told Tucker and Ruilai, and then stretched out his mental power to wrap a little fire essence and merge it into his body! "Humph!"

In an instant, the moment the essence of fire merged into his body, Rhett frowned and let out a muffled groan.

This method of direct absorption is still too rough, which is equivalent to forcing the origin into the soul.

After all, when normal people comprehend the mystery, they control this power imperceptibly and nourish their spirit silently. But at this moment, Rhett's way of devouring the essence of fire was much more direct.

Fortunately, the amount absorbed each time is extremely small, and the surrounding gray fog is also integrated into the body during this process, helping the soul to absorb it smoothly. Otherwise, if it were placed in reality, even if he encountered this kind of original power, Rhett would not dare to guarantee that he could absorb it smoothly.
