Sacrifice, my Gang!

Just as when he absorbed his spirit ring, the spirit power within it could be used to clear his meridians.

After feeling that surge of dry, hot warmth in his abdomen, Yu Tianchen tentatively used his spirit power to block a portion of the energy, beginning to use it to clear the meridians required for cultivating the Great Sun Thunder Body.

Sure enough, it was just as Yu Tianchen had anticipated.

This method of operation was feasible.

Moreover, the remaining Whale Rubber energy that Yu Tianchen had not yet mobilized was also continuously tempering his physical body, combined with the absorption of the external medicinal bath.

Thus, he was currently undergoing a dual-tempering of the body.

And he had entered a very positive cycle.

Clearing the meridians could expand his spirit power storage, increase the amount of spirit power absorbed into his body, advance the progress of his Great Sun Thunder Body cultivation, and his physical body would also be strengthened as the meridians were cleared.

At the same time, the energy from the Whale Rubber was also refining Yu Tianchen's body with the assistance of the medicinal herbs.

With his body strengthened by the Whale Rubber, the speed at which he cleared his meridians also increased slightly.

Although it did not seem obvious at the moment, as time went on, the benefits brought by this improvement would become very clear.

Knowing the benefits that the Whale Rubber could bring him now, Yu Tianchen did not hesitate.

After his parents returned that night, he immediately asked his father to acquire more Whale Rubber that was over a thousand years old.

And the next day, after seeing Yu Yuanzhen, he brought this matter up with him as well.

Regarding Yu Tianchen's demand for Whale Rubber, both Yu Yuanzhen and Yu Xiaotian readily agreed.

Furthermore, Yu Yuanzhen brought Yu Tianchen to the mimicry cultivation ground he had specifically prepared for him.

Located at the mountain peak, the thunder energy here was dense.

It could be considered a cultivation site specifically created for Yu Tianchen by Yu Yuanzhen and the various elders.

The mountain peak made it more convenient for Yu Tianchen to use the Five Thunder Shock Drums to draw down lightning, and supplemented by the surrounding thunder energy, his cultivation efficiency would only increase exponentially.

To make it even more convenient for Yu Tianchen to cultivate, they even built a courtyard for him right next to it.

This way, if Yu Tianchen cultivated late and didn't want to go back, he could stay there directly.

Yu Tianchen was, of course, very satisfied with this.

From then on, he moved in directly.

Every day, he was either developing ways to use lightning within the mimicry cultivation ground, or soaking in medicinal baths, refining the energy of the Whale Rubber, and using the Five Thunder Shock Drums to draw down lightning to cultivate the Great Sun Thunder Body.

Just like that, in the blink of an eye, two years passed quickly.

On this day, in the mimicry cultivation ground at the mountain peak, Yu Tianchen sat cross-legged on the ground. Faint lightning patterns diffused from his body, and his skin took on a faint bronze metallic luster.

Above his head, the Five Thunder Shock Drums flickered with bright thunder light, continuously drawing the lightning from the sky and the surrounding thunder energy into Yu Tianchen's body.

As these lightning bolts and thunder energy continuously entered, the original bronze luster on Yu Tianchen's skin began to fluctuate, constantly transforming toward the state of jade-like textures.

But upon reaching a certain point, this transformation process came to an abrupt halt; no matter how the lightning and thunder energy bombarded him, there was no further change.

After a long while, when the surrounding thunder energy gradually dissipated, the Five Thunder Shock Drums also gradually retracted their thunder light and returned to Yu Tianchen's side.

He slowly opened his eyes, exhaled a turbid breath, and his expression carried a hint of disappointment.

"Did the attempt to break through to the Jade Thunder Body fail after all..."

Two years had passed.

For Yu Tianchen, the rise in his strength was obvious.

Not only had he successfully mastered the full-power activation state of the Five Thunder Shock Drums, but his Great Sun Thunder Body had also successfully broken through to the first level, the Bronze Thunder Body.

His spirit power had broken through to level 20 a year ago, and after absorbing his spirit ring, it had now reached level 27.

The reason he could reach such a high level was mainly because his second spirit ring was absorbed from a Mystic Nether Thunder-Armored Rhino of about four thousand years, which allowed him to leap directly from level 20 to level 23, while also allowing his Great Sun Thunder Body, which had been on the verge of a breakthrough at the time, to successfully reach the first level of the Bronze Thunder Body.

But it was a pity that this year, Yu Tianchen had tried to break through the Great Sun Thunder Body to the second level, the Jade Thunder Body, but he had never been able to do so, and could only cultivate his spirit power based on the foundation of the first-level Bronze Thunder Body.

In his control of the Five Thunder Shock Drums, he had also been unable to convert normal lightning into Ultimate Thunder.

Only when fully activated would the lightning he used turn into Ultimate Thunder.

"Should I sacrifice Gangzi again?"

Yu Tianchen once again had some thoughts about Yu Xiaogang.

When his spirit power reached level 20, the system gave him 4 sacrifice opportunities.

It was just that at the time, Yu Tianchen had to hunt for spirit rings, cultivate the Great Sun Thunder Body, and develop the Five Thunder Shock Drums.

On top of that, he had just sacrificed Yu Xiaogang a year ago, and if he sacrificed him again, Yu Tianchen was afraid of ruining such a good sacrifice material.

So, he had kept these four sacrifice opportunities unused.

It seems it is time to put it to use.

People really ought to learn how to be content.

I have already given you two years to catch your breath; now, it is time for you to suffer a little, Gangzi!

"System!"

Yu Tianchen summoned his system.

A pale blue screen unfolded.

After locking onto the sacrifice target as Yu Xiaogang, Yu Tianchen pressed the red button directly.

"Sacrifice yourself, my Gang!!"

[Ding! Sacrifice and tribute initiated!]

[Selected Target: Yu Xiaogang]

[Initiating sacrifice...]

[Sacrificer: Yu Xiaogang, Innate Soul Power: 0.5, Soul Power Level: 24]

[Host: Yu Tianchen, Innate Soul Power: 10, Soul Power Level: 27]

[Sacrifice successful! Yu Xiaogang's Soul Power Level permanently reduced by 3, private parts shortened by 5, and enters a temporary state of kidney deficiency for a duration of three years.]

[Congratulations to the host for obtaining the tribute: Eight Gates Resonance Method]

[Eight Gates Resonance Method: A secret skill that allows for synchronous resonance through the body's eight major acupoints, detonating stored soul power to provide an all-around boost.]

[Eight Gates Acupoints: Consists of Space Gate, Gate of Healing, Gate of Life, Gate of Pain, Gate of Limit, Gate of View, Gate of Wonder, and Gate of Death; every two acupoints resonating together provides a two-fold all-around boost, and with all Eight Gates open, the multiplier can reach 10 times.]

[Warning! Acupoint resonance will significantly increase the burden on the body. Opening all Eight Gates will result in a period of weakness, the duration of which depends on the user's physical constitution.]

"Eight Gates Resonance... why does this feel a bit like the Eight Inner Gates from Naruto?"

Feeling the secret technique he had just acquired, Yu Tianchen couldn't help but mutter to himself.

Although it was somewhat similar, there were still many differences.

The biggest difference was that even if all Eight Gates were opened, one would only fall into a period of weakness, and if one's physique was strong enough, this period of weakness could be greatly reduced.

It wouldn't be like the Eight Inner Gates in Naruto, where opening all eight gates basically meant game over.

That said...

If he opened all Eight Gates, could he pull off a Night Guy just like Might Guy?

"Since there's nothing else to do right now."

"I'll start by practicing and testing it out."

Yu Tianchen closed his eyes and began to attempt to cultivate this secret technique.
