Billy decided to change his strategy a bit. While he didn't have all the mana he could, he couldn't just go for the kill as well. He had to slowly damage the beast and then make it lose all the means of attacking. With that in mind, he charged as fast as possible toward the enemy's head in order to fool it. When the beast tried to block his path with the remaining hand, Billy used Gungnir on the wrist of that same hand and cut it off completely. He had to use a lot of mana and stamina, but at least Billy managed to achieve his goal and made the beast even lose its balance. He smirked due to the success, but he soon calmed down again since that was just the start of his plan.
"I need to be careful of the arms, but it will be harder for that thing to hit me now…" Billy thought.
When the beast recovered, it suddenly felt one of its feet getting chopped. At least one-third of the right one had been cut and made the monster lose its balance. In response to that, the beast kicked the samurai and made dozens of them fly to the distance… It was hard to imagine them surviving that. In any case, they had come knowing full well that something like that could happen, rather, it was bound to happen considering all things.
Billy tried to ignore that since he was the one who was in the most danger, and he couldn't lose his focus. Despite that, he used Light Spear several times to make the monster stops moving. He tried to hit the eyes of the beast, but it was hard to imagine that it would change anything if the monster went blind. It was a golem, after all.
Suddenly, Billy had an idea, and then he charged toward the neck of the monster. However, the ice titan protected that area with both arms and then used Frost Breath.
"I see… The neck really is its weak spot," Billy thought while smirking.
If Billy manages to cut off the neck, the titan won't be able to do much aside from using Cold Aura and Frost Breath. Those would be enough to buy some time to repair itself against most enemies, but not against Billy. As if the creature could read his mind, the monster used Cold Aura again, and instead of attacking him directly, the monster raised its arms and made several ice spears fall from the sky.
Billy easily blocked them, but he was unable to do anything else since the Aura would decrease his speed, and the attacks would be harder to block. To make things even more annoying, the samurai were having a hard time blocking the ice spears. Meanwhile, the ice golem was healing itself. Billy didn't want to believe that, but the creature probably could use some spells at the same time and without running out of mana.
"I need to solve this as fast as possible…" Billy thought while clenching his teeth.
Billy took a deep breath to calm down and analyze the situation. He couldn't approach the enemy carelessly while the cold Aura was active. The rain of ice spears was also a problem in the long run since the samurai were having a hard time attacking and defending. Still, with their numbers, they could be useful under the right circumstances. Fortunately, Billy found a way to solve all of those at the same time.
Sei frowned when he saw Billy landing nearby. He wasn't surprised that he couldn't fly for so long… He never heard of anyone that could fly, after all. Still, instead of talking with him and seeing what they could do together to stop the beast, he decided not to approach since he could tell that Billy had some kind of plan in mind.
"That is going to hurt, but it can't be helped…" Billy thought.
After preparing for a short while, Billy used Flash toward the right feet of the monster. At the last moment, he ended up colliding against that, and he felt like a massive block of steel had smashed him. Fortunately, his plan worked… At the same time, he used Flash he also Gungnir, and the combination of both not only made the ice titan stumble backward but it also chopped the right ankle of the beast… The creature began to fall backward since it had lost one of its pillars of balance…
"Surround it and take huge chunks of its body!" Billy shouted.
At first, the samurai hesitated in following the orders of someone who wasn't their commander. Still, since Sei and his men saw Billy fight by himself for quite a while in the last few days, they decided to follow that command. Besides, they also knew that a chance like that wouldn't come often. Once the first group began to move, the others quickly followed.
While Billy's body was hurting like hell, he still jumped and then landed on the top of the monster's head. The creature tried to get up and smash him at the same time, but Billy quickly put his glaive on the monster's head and enchanted it with an electric current. The powerful magic paralyzed the monster due to the surprise, and it also granted Billy some extra piercing power.
The beast began to contort while trying to fight back and eventually began to move better, but Billy didn't stop. The ice giant also began to use Cold Aura again, but no one stepped back. The samurai, their commander, and Billy, all kept attacking the monster. The pain and discomfort caused by the extra cold only served as a fuel to boost Billy's anger and strength. He kept moving forward even when he began to lose the feeling at the end of his limbs. Somehow, he didn't lose the strength in his grip, and then eventually, his glaive reached the core of the beast.
