I can only trouble you a little, Gangzi

A pale blue screen unfolded before Yu Tianchen.

The system interface remained as concise as ever.

Only the grey, unusable button on the screen had changed.

It was now a vibrant red.

"System, come out and explain your functions, won't you?"

Yu Tianchen tentatively called out to his system.

No sooner had he spoken than the mechanical voice that had sounded during the awakening ceremony echoed in his mind.

[Received, initiating explanation function...]

[This system is named the Sacrificial Offering System. Every ten levels, you may obtain a random number of sacrificial offering opportunities. The worse the sacrificer's aptitude or the greater the level gap between the host and the sacrificer, the greater the value of the offering obtained.]

[Detected host's current Soul Power Level: 10, possessing one sacrificial offering opportunity.]

[Warm reminder:]

[1. The sacrificer must be a Spirit Master or of higher cultivation.]

[2. The sacrifice will cause the sacrificer to suffer a certain cost; the greater the offering the host receives, the greater the cost that must be borne.]

[Please use the sacrificial offering opportunity with caution!]

Listening to the system's explanation, Yu Tianchen's expression grew increasingly strange.

It wasn't that he didn't understand.

The system's explanation was concise and clear, making it quite easy for Yu Tianchen to grasp.

It was just... why did this system feel so sinister?

After the system finished its explanation.

Yu Tianchen looked at the red button before him, his face filled with hesitation.

He currently had one sacrificial offering opportunity.

As for someone with poor aptitude, he actually had a candidate in mind.

In terms of innate level and aptitude, there was an absolute gap between that person and himself.

That's right.

Yu Tianchen's candidate.

Was none other than his second uncle, Yu Xiaogang, known as the Master of Spirit Theory.

With an Innate Soul Power of 0.5, there was an absolute gap compared to his own Innate Full Soul Power.

He was simply the perfect candidate.

But if he did this, wouldn't it be a bit wrong?

Yu Tianchen hesitated; to sacrifice another person just for his own growth was a behavior that was truly a bit...

"Sigh, forget it."

He let out a soft sigh, raised his hand, and pressed the sacrificial offering button.

"Don't blame me, Gangzi."

"Who told you to be such a perfect fit."

"For the sake of your nephew becoming stronger."

"I can only wrong you a little bit."

[Ding! Sacrificial Offering initiated!]

[Selected: Yu Xiaogang]

[Initiating sacrifice...]

[Sacrificer: Yu Xiaogang, Innate Soul Power Level: 0.5]

[Host: Yu Tianchen, Innate Soul Power Level: 10]

[Sacrifice successful! Yu Xiaogang's Soul Power Level permanently reduced by 5, bad luck increased threefold, duration one year.]

[Congratulations to the host for obtaining the offering: Great Sun Thunder Body]

[Combined with the world the host is currently in, the modification of the Great Sun Thunder Body is complete.]

[Great Sun Thunder Body: A top-tier body-refining technique. It can draw upon thunder to combine with soul power to temper the physical body, clear the meridians, and condense soul power vortices beneath the skin. It is divided into three realms: Bronze Thunder Body, Jade Thunder Body, and Great Sun Thunder Body.]

As the system's voice faded, a profound technique suddenly appeared in Yu Tianchen's mind.

Feeling the technique in his mind, a look of joy appeared on Yu Tianchen's face.

Gangzi! My dear, sweet second uncle!!

You sacrificed so well!!

At the same time, in Notting Academy.

Yu Xiaogang, who had just settled down, suddenly turned pale. His feet went unsteady, and he collapsed face-first onto the ground.

Because he landed on his face, his front teeth were knocked right out.

But he couldn't care about the pain now; Yu Xiaogang's face flushed red as he let out a roar of extreme agony:

"Ahhhhh!! No!!!!"

"My Soul Power Level!!"

Just a moment ago, he could clearly feel it.

His already mediocre Soul Power Level had suddenly begun to plummet.

It dropped straight from level 29 to level 24!

A full five-level drop!

One had to know that every single level he had cultivated to this point had cost him countless hardships and effort, consuming endless resources from the Blue Lightning Tyrant Dragon Clan!

Being stuck at level 29 was already agonizing enough for him.

Now, he had regressed all the way back to level 24.

How was this any different from taking his life?!

Damn it!

What on earth was going on?!

Yu Xiaogang stood up in a disheveled state, but before he could even steady himself, his feet slipped again as if they had been greased.

Bang!

His forehead struck the exact spot where his two front teeth had fallen out during his previous tumble, leaving a deep mark.

"Ahhhhhhh!!!!"

The small room was filled with Yu Xiaogang's roars, a mix of impotent rage and excruciating pain.

At this moment, Yu Tianchen was unaware of what had happened at Notting Academy.

He sat cross-legged on his bed, five small drums flickering with lightning hovering above his head.

Fine strands of lightning were continuously released from the Five Thunder Shock Drums, entering his body through his pores and circulating through his meridians alongside the soul power flowing within him.

To achieve the first stage of the Great Sun Thunder Body, one needed to clear 43 basic meridians and form soul power vortices beneath the skin.

This process was undoubtedly painful.

Fortunately, Yu Tianchen had been training his body since he was young, and in the last two years, he had even consumed low-age Whale Rubber to strengthen his physique.

Therefore, this level of pain remained within his range of tolerance.

Moreover, by using the lightning provided by the Five Thunder Shock Drums for his cultivation, he could simultaneously improve his control over lightning and increase his soul power while practicing the Great Sun Thunder Body.

It could be said that he was killing multiple birds with one stone!

A moment later, the Five Thunder Shock Drums above Yu Tianchen's head gradually ceased their discharge of lightning.

He slowly opened his eyes and exhaled a breath of turbid air.

"Given my current soul power, can I only sustain it for this long without drawing upon external lightning?"

Yu Tianchen murmured softly.

Cultivating the Great Sun Thunder Body through the Five Thunder Shock Drums was an experiment for Yu Tianchen.

The facts proved that he had succeeded.

The Five Thunder Shock Drums could indeed be used to cultivate the Great Sun Thunder Body even without drawing upon external lightning.

It was just a pity that cultivating the Great Sun Thunder Body this way meant the soul power consumed to condense and release the lightning was completely disproportionate to the soul power gained, making continuous cultivation impossible.

However, if he were to draw upon external lightning for tempering, there shouldn't be any issues.

Simply using the Five Thunder Shock Drums to channel external lightning did not consume much for him.

Overall, Yu Tianchen was very satisfied with this cultivation technique obtained through Yu Xiaogang's sacrifice.

Second Uncle! Your contribution was all worth it!

This technique is quite smooth~

He retracted the Five Thunder Shock Drums from above his head, stood up to stretch his body, then walked over to the bookshelf, pulled out a notebook, and sat down at the desk nearby.

The cultivation technique was now settled.

For now, it was time to start researching how he should walk his path in the future.
