In Olivia Smith's previous life, his most skilled and habitual hand was his left, and in the army, he was even nicknamed the 'Left-Handed King'. After coming to this world, he brought this habit with him as well. With the memories of using his left hand before, plus a period of deliberate training, now his left hand, aside from being slightly weaker in strength, is even more dexterous than his right.

William Parker, however, was still a bit hesitant. He glanced at Olivia Smith's pair of hands, hesitated for a moment, and finally nodded. Compared to his young master's use of a knife, wielding a sword with the left hand was still barely within his range of acceptance.

At this moment, Olivia Smith gave a calm smile, stepped forward three paces, and attacked with a sword. It looked soft and powerless, yet William Parker's expression grew grave as he let out a tiger's roar, sidestepped and spun around, delivering a horizontal slash. The Furious Underworld King's Axe, combined with the fire attribute spiritual power from the Grand Dust Transformation Force, made the entire space heat up in an instant.

Olivia Smith's internal energy cultivation was only at Warrior Level Two, so he could only temporarily avoid the edge and retreat slightly. Then, in the image interface projected in his mind, the auxiliary intelligent system instantly provided fourteen different response plans. However, Olivia Smith frowned and carefully distinguished them, finding that not a single one was feasible. Still, the intelligent system's analysis was somewhat useful; although the response plans weren't great, it had calculated William Parker's current weaknesses and flaws very clearly—just without factoring in William Parker's sixth-level warrior internal energy and explosive power.

—But with his combat experience, just this much was already more than enough!

It was as if he hadn't noticed William Parker's next move, another vertical slash from the Furious Underworld King's Axe called 'Furious Asura Slaughter'. Olivia Smith, instead of retreating in the face of the oncoming fire spiritual power, advanced and delivered another soft, unhurried sword thrust toward William Parker's left rib. The latter reacted as if seeing a venomous snake, forcibly withdrawing the powerful axe strike and stepping back, using the axe—almost the size of a door panel—as a shield in front of him.

At this point, William Parker's face had turned a bit pale. This wasn't due to the depletion of true energy, but rather from using the wrong force just now. Yet Olivia Smith secretly praised him: for William Parker, with less than seventh-level warrior cultivation, to wield the Furious Underworld King's Axe and be able to both unleash and withdraw its power, was truly rare. The brute strength in this kid was no exaggeration.

From then on, every step Olivia Smith advanced, William Parker would retreat a step, actually suppressing Olivia Smith's seemingly powerless swordplay. For a while, Olivia Smith could do nothing about him. The Furious Underworld King's Axe excelled at offense but not defense, but the axe in William Parker's hands, used as a shield, was enough to make up for this flaw. The Grand Dust Transformation Force, with both fire and earth attributes, was as fierce as flames when attacking, and as solid and weighty as earth when defending.

After dozens of steps, William Parker was forced to the edge of a small stream. Seeing that he could push this silly kid into the creek and seize victory while his footing was unstable, Olivia Smith finally 'remembered' his real purpose this time: to point out William Parker's shortcomings in using the Furious Underworld King's Axe, not just to defeat him as before.

With an apologetic smile at his opponent, Olivia Smith withdrew his sword. William Parker immediately understood his intention and switched from defense to offense. This time, it was the fifth move of the Furious Underworld King's Axe that he had practiced that morning.

Olivia Smith gave a slight smile, raised his sword horizontally, and for the first time let his weapon clash with William Parker's axe. But before the berserk internal energy and brute force of the sixth-level warrior could be transmitted, Olivia Smith's sword twisted and led the force aside, diverting the terrifying power away. Pulled by this force, William Parker staggered forward several steps with his axe.

But at this moment, Olivia Smith wasn't feeling great either. This Taiji method of redirecting force was something that, in his era, any ancient martial arts practitioner would know at least a little, and Olivia Smith was especially skilled at it. However, in this world, due to his age and some special reasons, his footing was still unstable. Not to mention redirecting force, even neutralizing it was a bit forced. Though he managed it this time, his own steps became disordered, and he nearly fell.

The next few times were much the same. William Parker cycled through the fourth to seventh moves, but without exception, Olivia Smith redirected them aside. It wasn't until the ninth time that William Parker finally stopped, a look of sudden realization on his face.

"Young master, am I using too much force?"

William Parker scratched his head and wiped the cold sweat from his brow. Earlier, when Olivia Smith redirected his force, although his own steps became disordered and he couldn't counterattack, if it had been someone else equally skilled at neutralizing force, just one sword thrust as he lost control and lunged forward would have killed him countless times by now.

"Not entirely! In short, from now on, when you use the axe, if your opponent is human, just use sixty percent of your strength. Will, you still need to work on your footwork. Otherwise, even the smallest force will be uncontrollable."
