Light Devil Fruit in Tales of Demons and Gods

Snow Wind Family Training Ground

Standing before Ye Xinghan was a lean youth, approximately 15 years old.

In Glory City, noble families often sponsored apprentices from outside their own lineage—an accepted and strategic practice.

 Promising young commoners who attended the academy were selected and groomed.

 This helped train noble family members in leadership while securing loyal subordinates after they graduated.

For the commoners, this opportunity was invaluable. They gained the support of powerful clans, significantly advancing their training while also earning resources to support their families. It was a mutually beneficial arrangement.

The youngster before Ye Xinghan was one such individual. Chosen by the Snow Wind Family, Lin Ming was expected to achieve at least Silver Rank Demon Spiritualist status in the future.

"Young Master Xinghan, this is Lin Ming. He will be your sparring partner today," announced Head Servant Feng, gesturing for the youth to step forward. Feng then moved aside to oversee the match and ensure safety.

"Greetings, Young Master. Please show mercy," Lin Ming said respectfully, cupping his hands and assuming a battle stance.

Ye Xinghan nodded and readied his stance. "Please show mercy as well."

"Three, two, one… Sentou Kaishi!" Head Servant Feng shouted, signaling the start of the match.

"Young Master, be careful!" Lin Ming charged forward, aiming a punch at Ye Xinghan. With his superior strength and experience, Lin Ming saw no need to play defensively.

Ye Xinghan narrowly dodged and countered with a blow to Lin Ming's jaw.

Lin Ming noticed the incoming punch but chose not to dodge or defend. After all, Ye Xinghan had yet to cultivate any strength. There was no way the attack could harm him.

Sure enough...

PENG!

Ye Xinghan's fist struck Lin Ming like hitting a wall. Wincing, he leaped back and examined his slightly reddened hand. 

Lin Ming stood unfazed, without a hint of mockery. He knew there was nothing to be proud of in overwhelming a child.

"Come again!" Ye Xinghan shouted, determined.

Lin Ming charged forward with a flurry of punches, carefully controlling his strength to avoid injuring the young master. 

Ye Xinghan dodged desperately, relying solely on combat experience from the One Piece world. 

However, his current body lacked the strength and reflexes to match his former self. 

It was like having a level 100 game account with all skills maxed out, only to be reset to level 1 with nothing but memories of how to grind back up.

With his new body unable to keep up, Ye Xinghan was steadily cornered until—

BAAM!

Lin Ming's punch landed squarely on Ye Xinghan's chest, sending him flying back five meters.

Head Servant Feng sighed inwardly. "It seems it's still too early for the young master to face a three-star bronze fighter. Hopefully, this will teach him some humility."

Just as Feng raised his hand to end the match, a voice interrupted him.

"Wait, it's not over yet."

Ye Xinghan stood up, his face bruised and cut but his movements steady. He showed no signs of internal injury.

'This Lin Ming is impressive. He perfectly controls his strength, ensuring I'm not seriously injured. Neither arrogant nor overly humble—what a talent.' Ye Xinghan thought, looking at Lin Ming with newfound respect.

To outsiders, Ye Xinghan's actions might seem reckless, as if he'd bitten off more than he could chew. But he had a purpose—he wanted to compare his reflexes and instincts before and after using the devil fruit.

"Lin Ming, thank you for holding back earlier. Let's go one more round," Ye Xinghan said, smiling as he resumed his stance. This time, he channeled a small amount of his light devil fruit energy into his brain, the same as when he studied ancient languages.

Head Servant Feng sighed but nodded. "Do as the young master commands."

Raising his hand, he began the countdown.

"3 , 2 , 1. Sentou Kaishi!"

Lin Ming rushed toward Ye Xinghan, using what he thought was enough power to overwhelm the young master.

However, Ye Xinghan's perspective had completely changed.

This time, everything seemed slower in his eyes.

"Is this… time dilation?" Ye Xinghan wondered. His body wasn't moving faster than before, but his vision now perceived time at a much slower rate.

"When an object moves at the speed of light, the world around it appears frozen or stagnant. In other words, achieving the speed of light is akin to stopping time itself."

Lin Ming wasn't actually moving slower; it was Ye Xinghan's brain operating at an accelerated speed, granting him unmatched perception and reaction.

This was a groundbreaking discovery.

Back in the battle, Ye Xinghan easily evaded Lin Ming's punch. Lin Ming followed with a barrage of attacks, but Ye Xinghan dodged each one effortlessly, looking completely at ease.

Lin Ming frowned and increased his punching speed, pushing himself to his limit.

 Even so, Ye Xinghan managed to dodge, though with visible effort this time.

Head Servant Feng observed thoughtfully. "What's going on? Lin Ming is among the best three-star bronze ranks, yet he can't land a single hit on Young Master Xinghan."

Finally, Lin Ming launched a kick at Ye Xinghan. 

With his enhanced perception, Ye Xinghan stepped onto the incoming leg, using the kick's force to propel himself into the air.

"Time to end this battle," Ye Xinghan decided mid-air. There was some distance between Lin Ming and the spot where Ye Xinghan would land.

"Soru!" As soon as he landed, Ye Xinghan used a pseudo-Soru technique to close the gap in an instant.

"So fast!" Both Lin Ming and Head Servant Feng widened their eyes in disbelief.

'I can't deal substantial damage to Lin Ming with an ordinary punch, and I don't want to reveal my devil fruit abilities just yet. That leaves only one option,' Ye Xinghan thought as his eyes gleamed with determination.

He channeled a small amount of his devil fruit energy into his shoulder and elbow joints to protect his body from injury.

"Shigan!" 

But instead of using his finger, Ye Xinghan used his elbow, aiming to create an aerial impact rather than penetration damage. The devil fruit energy enhanced the speed of his arm as he swung.

Sensing the danger, Lin Ming immediately crossed his arms to defend.

"BAAAAM!"

The strike landed, sending Lin Ming flying into a nearby boulder, which shattered upon impact. Blood trickled from the corner of Lin Ming's mouth.

Head Servant Feng stood frozen, his jaw slack with shock.

'What just happened?' He looked at Ye Xinghan like he looked a monster. 

"Alright, let's leave it at that," Ye Xinghan said, clapping his hands to snap Feng out of his stupor.

"Head Servant Feng, please check Lin Ming's injuries and treat him immediately if anything serious arises."

"Yes, Young Master."

Ye Xinghan nodded and walked off to change his clothes. The purpose of the sparring match had been fulfilled.

"Hmmm, the state I enter when channeling the devil fruit energy into my brain is so overpowered. Let's call it…"

"God Speed Impulse."
