At the Xiao family's Divine Ability Tower, when Lin Fei arrived, he found the tower devoid of any Martial Sovereigns. Only a guardian elder from the Xiao family stood watch. Lin Fei had anticipated a sparse crowd, but the absence of even a single figure was unexpected. However, he could speculate why.

Martial Sovereigns of the Martial King lineage were primarily focused on awakening their bloodline. Once awakened, it would trigger the manifestation of a Great Divine Ability. Why would they then painstakingly come to practice other Divine Abilities? Especially when mastering those abilities wasn't guaranteed. Thus, the Divine Ability Tower seldom saw the presence of Martial Sovereigns.

As Lin Fei stepped into the tower, the guardian's eyes snapped open. Without hesitation, Lin Fei produced Xiao Yuchen's token.

"Ah, the token of little Yuchen," the guardian elder observed, "You must be Sovereign Lin."

Given the way he addressed her, the guardian elder was likely an elder relative, perhaps of a previous generation, to call Xiao Yuchen in such an informal manner.

Lin Fei nodded in respect. "I am Lin Fei. I wish to enter and practice the Divine Abilities."

"If little Yuchen has entrusted you with her token, it serves as your voucher. However, you are only permitted on the first floor to practice the Lesser Divine Abilities."

Understanding the stipulation, Lin Fei nodded and proceeded without further ado.

The first floor of the Divine Ability Tower was eerily silent and deserted, which to Lin Fei felt refreshingly serene. These Divine Abilities, though deemed 'lesser', were vast in number and diversity. Taking a deep breath, he drew forth the Heaven-ending Saber Divine Ability scroll from within.

"Seek and merge with the Divine Abilities that resonate with your essence," he murmured, addressing the scroll.

While most abilities here weren't saber-oriented, Lin Fei was curious. If the Heaven-ending Saber integrated with other Divine Abilities, would it still remain true to its saber path? Or would it evolve into a unique amalgamation?

Lin Fei's heart thrummed in anticipation.

Suddenly, a radiant aura, symbolizing the Heaven-ending Saber Divine Ability, burst forth, sweeping in every direction. Almost immediately, the entire floor was illuminated with countless luminescent strands, each representing a different Divine Ability.

The Heaven-ending Saber seemed more sentient now, emitting pulses of information, beckoning compatible Divine Abilities to merge with it.

However, trouble arose. Though the saber's radiance spread far and wide, no Divine Ability seemed to respond. After all, the Heaven-ending Saber, being just another Lesser Divine Ability, perhaps lacked the clout to persuade others to merge willingly.

"Heaven-ending Saber needs my intervention," Lin Fei mused, realizing that without his help, no Divine Ability would willingly merge with it.

In the next moment, he summoned his Life Wheel. A three-layered radiance beamed from the wheel, exerting immense pressure throughout the floor. It was backed by three top-tier Great Divine Abilities, a force that was almost suffocating.

"If you meld with the Heaven-ending Saber and evolve into a Great Divine Ability," Lin Fei began, his voice echoing, "you'll become a part of my set of Divine Abilities, granting you a place on my Life Wheel. And in the days to come, as I ascend to the rank of Martial King and birth the Martial King bloodline, you will integrate into it. An everlasting bloodline ensures the immortality of Divine Abilities!"

By saying this, Lin Fei was basically staking his claim. Heaven-ending Saber was his creation, and their bond was profound. The three top-tier Great Divine Abilities on Lin Fei's Life Wheel shone brightly. Their mere allegiance to Lin Fei spoke of his potential. The promise of immortality was hard to resist for any Divine Ability.

As anticipated, there was movement. A certain Divine Ability began to gravitate towards the Heaven-ending Saber. Approaching it, Lin Fei recognized it as "Mountain Suppressor." The name exuded dominance, and its power was undeniable. Yet, it was still only a Lesser Divine Ability. When unleashed, it could indeed suppress mountains, but when compared to regular Divine Abilities that could trigger cataclysmic events, it seemed insignificant.

However, it wasn't a saber-oriented Divine Ability. Lin Fei was unsure of how it would integrate with the Heaven-ending Saber, making this merge crucial. The philosophy behind both abilities was somewhat similar - they both prioritized raw power, an unstoppable force that could obliterate anything in its path. Their similarity in ideology was likely why Mountain Suppressor was drawn to the Heaven-ending Saber.

As time passed, the two luminescent entities continued to intertwine but had not yet completely merged. Then, in a sudden surge, both lights shuddered and instantly became one, its radiance growing even brighter.

"It worked!" Lin Fei exclaimed with joy.

At that moment, a voice from a system inside Lin Fei's mind echoed.

"The Heaven-ending Saber Divine Ability has fused with the Mountain Suppressor Divine Ability to form a new Great Divine Ability, the 'Heaven-suppressing Saber'."

"The Heaven-suppressing Saber wishes to be your Divine Ability."

Lin Fei observed the glowing aura from a distance.

"Has it evolved into a Great Divine Ability?" He recalled distinctly that the Heaven-ending Saber had previously fused with fifteen Lesser Divine Abilities. With the addition of Mountain Suppressor, it had absorbed a total of sixteen.

And now, its transformation was complete. Even its name had changed to "Heaven-suppressing Saber", indicating it still belonged to the Saber Dao of Divine Abilities. This confirmed that saber-related Divine Abilities could fuse with others, as long as their ideologies aligned.

Yet, Lin Fei didn't immediately accept the Heaven-suppressing Saber Divine Ability. It was still just a Great Divine Ability. He aimed higher; he sought a top-tier Great Divine Ability. Lin Fei also wondered about the limits of this newly-formed Heaven-suppressing Saber. How many more Divine Abilities could it assimilate before reaching its pinnacle?

"Continue fusing with more Divine Abilities until you reach your utmost potential!" Lin Fei commanded the Heaven-suppressing Saber.

One after another, beams of light representing Divine Abilities fused into the Heaven-suppressing Saber, further augmenting its prowess.

Seventeen, eighteen, nineteen, twenty... the count went on. When the number reached twenty-eight, there was a massive upheaval, and the Divine Ability underwent another transformation, glowing more intensely than before. And then, it stopped. No other Divine Abilities could merge with it any longer.

"Has it reached its limit?" Lin Fei pondered. He sensed that this Divine Ability had achieved the pinnacle of Great Divine Abilities. However, its true power could only be gauged once he began his cultivation.

"Return to me and become my Divine Ability. In the future, you will fuse into my bloodline. With an unending bloodline, the Divine Ability shall remain immortal!" With a gesture, Lin Fei beckoned the pinnacle of Great Divine Ability, and it immediately merged into his being.
