Sin proceeded upward through the floors, leaving the monsters untouched. His three wood clones acted in his stead, efficiently dispatching the enemies. This yielded Sin three times the force increment than he would gain alone. He hypothesized that the augmented Wood Cells in his body enhanced this force growth beyond the normal rate.
With the clones battling in his place, Sin could focus on analyzing the mechanics underpinning his sudden boost in force. The sharp increase in power gain per enemy seemed tied to the multiplication of clones. However, the scale of the growth exceeded what should occur from basic math.
Killing enemies provided force proportional to their strength. So tripling his clones should triple his force increment accordingly. But Sin's force rose by a factor greater than three times. This indicated the Wood Cells not only enabled clone multiplication, but also synergistically amplified his force income itself.
The added Wood Cells must optimize his internal pathways for force accumulation and growth. When combined with multiple clones accruing force simultaneously, this manifested as exponential expansion beyond direct proportionality.
Of course, there was a ceiling to this growth, as infinite force was impossible. But within reasonable boundaries, the Wood Cells compounded force income in tandem with additional clones. This explained the outsized force gain increase Sin experienced.
Rather than purely mathematical growth, the cells provided biological amplification, creating force efficiencies and systemic improvements within Sin's body. Force was produced, distributed, and assimilated at heightened capacity. The cells fundamentally upgraded Sin's physiology to process ever-greater force.
This supported more rapid enhancement of his abilities. The wood clones served as focused vessels channeling expanded force back into Sin. Without the cells, clones alone should not confer such a high force rate. Their benefits were interdependent.
Through this synergistic mechanism, the clones battled while Sin reaped force far exceeding typical parameters. This fed into swift growth, creating a positive feedback loop. Greater force let him sustain more clones, which enabled even higher force income.
Of course, cliffs likely existed where costs and force gain balanced out, representing the upper limit of this advantage. But within those boundaries, Sin could leverage this interaction for efficient short-term progression.
In the long term, there would be diminishing returns as Sin's personal force advanced. The relative force gains from enemies would shrink compared to his overall strength. But for now, he could exploit this temporary fast track to quickly develop his abilities.
Sin could have rested on this advantage and passively accrued force. But he chose to press forward and use the increased force for active training and improvement. Complacency would only slow long-term growth, so he remained focused on progressing beyond each new force threshold.
The Wood Cells and clones had accelerated his strength, but true might came from perpetual effort and evolution. Sin would integrate this biological boost into a comprehensive improvement regimen for balanced advancement. Through diligence and insight into the source of this force multiplier, Sin aimed to utilize it as a springboard toward greater heights.
Here is a 500+ word rephrasing and expansion of the sentences without a concluding paragraph:
With minimal effort, Sin's wood clone carried him swiftly up through the floors to the 50th level. Entering the chamber, Sin confronted his opponent - a colossal ursine beast barreling toward him. Sin dismissed his clone, reabsorbing it into himself. He stood his ground as the bear charged ferociously.
Clasping his hands, Sin summoned forth weaving wooden branches that erupted from the ground. The tendrils coiled around the bear, tightening to restrain its rampage.
Having halted the beast's advance, Sin paused to assess the situation. His clone had conveniently transported him here, but defeating the dungeon's guardian would fall to Sin alone. He needed to gauge his adversary's power properly.
The bear was formidable, far beyond any normal beast. Muscles rippled beneath its fur as it strained against the tightening wood bonds. Sin felt its immense strength as the branches creaked under pressure.
But the bindings held, keeping the creature at bay for now. Sin maintained his focus, ready to reinforce the restraints if needed. Only his full attention kept the thrashing bear contained.
Its size and power were great, fueled by otherworldly energy from the dungeon's depths. Still, Sin was undaunted. His goal was not merely to trap the beast, but defeat it in true combat.
Releasing the bear could be dangerous, but its full force remained unknown while limited like this. Sin needed to directly test himself against its unleashed fury. Holding it at bay proved nothing.
With a flex of his will, Sin dismissed the winding wood branches, freeing the bear. It wasted no time, immediately barreling forward like a freight train. Sin stood firm as tensed muscles exploded into motion.
The bear closed the gap in seconds, massive claw swiping. Sin pivoted away, the razor tips missing by centimeters. The next swing came instantly, swifter than its bulk implied.
Sin barely ducked under the blow, feeling the air ripple with its force. The bear pressed its advantage, claws and fangs attacking relentlessly.
Hard-pressed, Sin created subtle branches to redirect the strikes just enough to avoid injury. The bear was strong and skilled, experienced against agile foes. Sin could not yet overpower it directly. He needed an edge.
As they exchanged blows, Sin studied the bear's attack patterns, seeking openings in its offense. It used its mass for power but maintained agility. Sidestepping another furious lunge, Sin saw his opportunity.
When the bear overcommitted to a powerful straight-armed swipe, Sin made his move. Ducking inside its reach, his palm struck hard at the extended elbow joint.
The focused blow hyperextended the arm, and the bear's momentum carried it stumbling past Sin. Wasting no time, Sin sent a wooden spike from the ground to pierce the stumbling bear's thigh.
The beast roared in pain and whirled around, but favored its impaled leg. Sin had inflicted damage and compromised its mobility. Pressing his advantage, Sin went on the offensive.
The injured bear fought fiercely despite the handicap. But Sin had gauged its abilities now. He avoided kill shots, seeking instead to systematically weaken the great beast.
