Each time a technique was strengthened by +1, Su Xiaobai could clearly feel significant changes occurring within his body, and his strength would leap forward by a large margin!

Once he had strengthened every technique he could, Su Xiaobai then turned his attention to the relatively lower-grade materials.

"These low-grade materials are basically useless for anything other than alchemy and forging… Besides, they're too low-level. Even if I refine them into pills or spirit weapons, their value wouldn't be much, and mass production would bring in meager profits!"

"I might as well combine all of them into higher-grade ones and see if I can push for another wave of strengthening!"

The most powerful feature of One-Click Synthesis was not just that it could synthesize high-grade items — it could also maximize the value of low-grade ones!

Especially those leftover low-grade materials.

Through Auto-Mining, Auto-Collecting, and Auto-Combat, Su Xiaobai would constantly obtain some relatively low-level heavenly treasures… Materials that were tasteless to consume but a pity to throw away, whose greatest use was merely for basic alchemy and forging to barely scrape together some value.

However, with One-Click Synthesis, they now had tremendous use!

Every 4 low-grade materials could be synthesized into one material of the next grade…

And because low-grade materials were abundant, if they were all synthesized, Su Xiaobai could actually amass a considerable amount of high-grade materials!

These high-grade materials could not only be used for strengthening.

They could also be refined into high-grade pills and forged into high-grade spirit weapons!

One-Click Synthesis, in effect, became a side channel for Su Xiaobai to continuously create high-grade strengthening materials…

Honestly, it was no exaggeration to say that the profits it could generate were no less than the resource collection functions themselves!

Without further ado, Su Xiaobai immediately started selecting large batches of low-grade materials.

Among them were herbs, metal ores, special materials like Heavy Earth and Living Water… Anyway, as long as they met the four-in-one synthesis condition, he threw them all into the synthesis and upgrading process without a second thought!

"Ding! Synthesis successful, obtained 'Wenxin Ginseng'!"

"Ding! Synthesis successful, obtained 'Ten-Thousand-Mile Crystal'!"

"Ding! Synthesis successful, obtained 'Essence-Corrosion Treasure Rock'!"

"…"

Watching those low-grade materials, which were almost equivalent to trash, continuously transform into rare high-grade materials in his hands, Su Xiaobai couldn't help but grin widely… This feeling was just like picking up money, and it was simply too enjoyable!

Other people, even the most powerful figures in the Vast Domain, could never have dreamed of doing something like this!

Enhancement and synthesizing — purely exclusive to Su Xiaobai alone, without a second person.

In fact, Su Xiaobai could totally rely on One-Click Synthesis and One-Click Enhancement to scour the Vast Domain for opportunities and crazily rake in wealth multiple times… Turning those low-level materials, which everyone else sneered at and sold off at clearance prices, into rare treasures highly coveted by the lives of the Vast Domain in an instant!

Anyway, for Su Xiaobai, synthesis only required raw materials; there was no need for any additional consumption, and he didn't even need to manually sort and process them.

With just a command, the system would automatically scan, place, and synthesize new materials — why wouldn't he do it?

What is 'one-click'?

Isn't it about convenience, effort-saving, speed, and being something that others can't achieve?

Well, this was exactly it!

In just a short time, Su Xiaobai obtained a large batch of brand-new high-grade materials.

These high-grade materials were flawless, each one perfect and unblemished, and their value far surpassed ordinary materials of the same level!

Without any hesitation, Su Xiaobai threw all these newly synthesized high-grade materials into strengthening his techniques.

"Feels so good!"

"So satisfying!"

"This feeling of lying down and getting stronger is simply heavenly!"

Su Xiaobai was thoroughly enjoying himself.

The sense of power surge brought by strengthening was as intuitive as shadow fusion… Every single enhancement felt like a mysterious force flooding into his body!

Not only that, but every technique that was strengthened would glow with radiance.

+1 strengthening would emit green light.

+2 strengthening would emit blue light.

+3 strengthening would emit golden light.

+4 strengthening would emit purple light.

+5 strengthening would emit dark-gold light.

+6 strengthening would emit red light.

+7 strengthening would emit bright-black light.

Starting from +8 strengthening, it would turn into a two-tone mixed color, which Su Xiaobai referred to as 'Dual-Color Enhancement'!

Thus, after another round of strengthening, whenever Su Xiaobai casually used one of his enhanced techniques, he would shine with brilliant multicolored lights all over his body, resembling those 'whale player' avatars from low-quality browser games… yet it made him incredibly eye-catching and exuded an overwhelming dominance, making Su Xiaobai feel utterly comfortable!

Enhancement was simply too exhilarating!

"Ding! 'Golden Embryo Tempering Nether Scroll' reached highest level!"

"Ding! 'Xuanjin Rainbow Light Scripture' reached highest level!"

At this moment, the system prompts sounded — the two King-Grade techniques gifted to Su Xiaobai by Luo Yu had directly reached their highest levels!

Boom!

A massive and profound torrent of information was transmitted directly into Su Xiaobai's mind.

Behind him, two colossal phantom images materialized.

Centered around him, within a radius of tens of thousands of kilometers, everyone could feel an overwhelming sense of heart-pounding dread, as if suffocating… This was the oppression of a higher-level life form!

Everyone turned toward the direction of the Su Clan Manor, their eyes filled with deep fear and wariness.

Moments later, when the phantoms behind Su Xiaobai dissipated and he reopened his eyes, that oppressive aura quickly withdrew.

"My strength… has once again made a tremendous leap!"

Golden light flickered in Su Xiaobai's eyes.

He quickly checked his current state, wanting to know, after the strengthening and the addition of two King-Grade techniques, what level he had now achieved!

Human: Su Xiaobai

Realm Level: Demi-God Martial Commander

Strength Level: Fourth-tier Martial King Grade

Endurance Level: Fifth-tier Martial King Grade

Agility Level: Fourth-tier Martial King Grade

Cultivation Aptitude: Top-Class

"Comprehensively reaching Fourth-tier Martial King Grade, with endurance directly at Fifth-tier Martial King Grade!"

Excitement surged on Su Xiaobai's face.

The breakthrough of his Demi-God Martial Commander realm.

The full +1 strengthening across all King-Grade techniques, doubling their effectiveness.

And the addition of two newly mastered King-Grade techniques at maximum level.

When all these factors combined, it caused Su Xiaobai's strength to soar explosively!

"If I can perform another shadow fusion, then wouldn't that mean…"

The boost from shadow fusion couldn't be underestimated either.

At that point, it might truly be possible for Su Xiaobai to engage in a fierce battle with a Martial King level opponent… and as for who would come out on top, it would genuinely be hard to say!

"But now, at least I can be certain that climbing to the 108th floor of the Illusory Tower is no longer a problem!"

A flash of sharp light flickered through Su Xiaobai's eyes.
