Determined to weaponize the plants' unique properties, he devised a simple test—pluck a flower and hurl it at a goblin. While contemplating his plan, he couldn't help but marvel at his body's rapid healing. "Only three weeks, and my arm is as good as new," he thought, unaware of the subtle transformations within him.

Once more targeting a patrolling goblin, Henry prepared a spiked pit lined with the dried flower that seemed to absorb mana. The poison was weak but effective; it took time, but eventually, the goblin succumbed as it crystallized and turned to dust blooming small flowers from its purple ashes.

Over two weeks of trials followed as Henry sought to maximize the plant's potential. Inspired by anime tactics, he observed that uprooted plants could regrow rapidly when fed a mana source.

Emboldened, Henry provoked a goblin into combat, wielding a wooden bat scavenged from previous conquests. The goblin seemed to realise that its kin's disappearances were Henry's doing as it saw him wielding a goblin club. Their clash was fierce—clubs clashed with primal ferocity. Though small, the goblin was tenacious, but Henry's strength gave him an edge.

In a whirlwind of swings, Henry struck lucky—a reckless blow disarmed the goblin. Seizing the moment, he delivered a fatal strike. Green blood splattered; victory was his.

Wasting no time, Henry placed an intact mana-eating plant upon the fallen creature. As if sensing its meal, the plant's roots burrowed into the goblin's body, turning it to purple dust while releasing its toxic gas and taking root in the ground.

Satisfied with his growing combat prowess and understanding of this world's rules, Henry spent the following month engaging goblins in battle and refining his use of the plants—a warrior honing his skills for survival.

The ninth month had arrived marking 5 months since the incident, and Henry found himself gazing upon his reflection in the river's embrace. "My afro's really getting out of hand, and my beard's growing too," he noted with a hint of amusement. "But those are worries for a stress-free day. For now, I must focus on the present."

As he dressed, a sense of pride washed over him. "To think I've handled groups of six goblins, even four at once—I've really come far," he mused, a blush creeping onto his cheeks.

With preparations complete, Henry set his sights on a new goal. "Time to claim my new home," he grinned, as dawn's light kissed the horizon.

His plan to eradicate the goblin den was set in motion. As morning scouts and hunting squads departed, Henry trusted in his traps laid for each squad. One by one, he stealthily dispatched the guards with minimal effort.

With the den's entrance unguarded, Henry unleashed his gas bombs crafted from leaves and mana-eating plants into the cave. The seeds within promised to spread like wildfire, crystallizing anything with mana.

Inside the cave, Henry was an unstoppable force; most goblins fell without a fight—a seemingly clean victory. Yet, as he stood at the cave's mouth, he spotted the goblin chief returning from a hunt with its elite squad.

No time for thought—only action. Seeing Henry wielding one of their weapons bloodied with their kin's life, they charged at him enraged. Henry met their fury head-on.

The battle was fierce; two elite goblins wielding metal weapons fell before him. With precise throws of his gas bombs, three more crystallized instantly. The goblin chief along with the remaining two hesitated as one of the goblins—a spellcasting goblin began its chant.

Vines sprout and bound Henry's right leg, but Henry's resolve never wavered. With a deft throw of his shield and a swift dodge, he struck the elite goblins feet immobilizing it and dodged the charging goblin chief's attack using the opportunity to stab its heart from behind. With momentum on his side, he turned his body facing the spellcasting goblin hurling his sword at it—silencing it forever as the sword pierced its skull.

As the vines loosened their grip, Henry faced the last bewildered soldier. With raw determination, he charged at it knocking it to the ground delivered punch after punch until victory was undeniable as his fists were drenched in green blood.

Standing amidst the battlefield as the midday sun cast its judgmental gaze, Henry emerged triumphant as the battle ended the goblin were eradicated.
