Zajoth fired multiple blood spears to stop Billy while he was flying away, trying to buy time for himself to recover. At that point in time, Billy realized that he sure could summon a lot of blood… Even if he had the spell and mana to use it, and it would be weird to use mana to create blood… Regardless, Billy blocked those with his spear, and he approached the enemy.
Unfortunately, he didn't approach him faster or before the enemy's arm had been completely healed. Still, Billy only could hear a single heart beating, so the other heart still was damaged, and the strength of the enemy didn't decrease. Zajoth flew toward Billy and then summoned another spear for his next hand. Billy had planned to finish things as quickly as possible. Still, he was forced to assume a defensive stance while the enemy was attacking him furiously. Each stab pushed him away for dozens of meters, and the enemy always was quick to approach…
"At this rate…" Billy clenched his teeth when he noticed that his armor was losing more mana than he could steal.
Billy had already suffered some wounds, and he would get more once the armor stopped working. So, he truly had to hurry… After a few seconds, he found his answer. Billy used Body Enhancement, Emotional Control to increase the level of his Rage beyond the limits, and then he charged at the enemy by his enhancing his spear with the powers of Severe Blade and Physical Disturbance.
Zajoth blocked the first strike with a single spear, but he regretted that when he was thrown to the distance, and his whole body trembled. Moreover, he felt himself getting tired… He soon recovered, but that was a feeling he didn't have in a while…
When Billy approached again, he used both spears to block the attack, and this time, he wasn't pushed backward. The impact caused by the collision of the weapons made the entire area vibrate, and some lightning bolts flew from their bodies while both of them were trying to overpower the adversary while clenching their teeth.
For the first time since the battle started, Zajoth was forced to think a little… He had heard that Billy was pretty strong for someone who was a hybrid of mage and warrior, but he wasn't warned that he could become that strong… One had to steal nerves to try to have a showdown of brute strength against Zajoth…
Zajoth had some options to win the exchange, but relying on tricks when they were on equal terms when it came to power wasn't an option. He simply waited for his Rage to grow and thus buff his strength… When Billy began to be pushed backward, he realized that he needed to do something. Reacting like usual would be a waste of time. He had to completely shock the enemy with a demonstration of Absolute power.
In the end, Billy just waited until the enemy overpowered him. When Zajoth finally pushed him away and charged for impaling his head, Billy used Mana Shield and Reflect. The total power of the attack was sent back to the enemy, and Zajoth was pushed away for dozens of meters.
Before the enemy could recover, Billy used Beastly Possession and made the fire elemental help him while he charged toward the enemy. When the enemy finally began to slow down, Billy used Gungnir, and at the same time, he threw his weapon at the enemy with all his might. It was the same combination he used against Zenis before, so he knew the power behind it…
Unfortunately, the enemy blocked both of the attacks with his spears while being pushed backward. Zajoth wouldn't fall for another attack coming from behind… So, Billy used something new. He summoned two spears using Mana Constructs, and with all the remaining he had, making them three meters long, and then he dashed toward the enemy.
Zajoth prepared to receive the attack, and then he frowned when he saw Billy suddenly spinning at fearsome speeds. Zajoth blocked the attack, but soon Billy's attack aimed at the enemy's remaining heart began to push him away as well… Both of the enemies' spears broke, and then they pieced the right chest of the enemy.
Billy and the enemy spinner for a while, but eventually, they stooped. While both of them were dizzy, Billy realized that the enemy would need to lose his head as well… Before the enemy could recover, Billy finished the job.

Billy didn't rest as soon as he received those notifications… Only after a while did he calm down and deactivate the skills. Thanks to that, Billy began to suffer a lot of pain since he put his body into a difficult situation. Regardless, he didn't have time to rest, and he had to keep working until the portals stopped opening and bringing more of the invaders to that world. The task sure would be difficult, but he wasn't alone, and that was probably one of the things that kept him going.
Still, when Billy prepared to use Temporal Vision, he felt that the mana on that world was returning to normal. He checked things with his wives, and he saw them fighting around some cities, and the portals weren't being opened anymore. When he checked things with that red planet, he saw it moving away… the battle was over, and apparently, the new leader of that world didn't want to continue the fight… pretty reasonable coming from one of those. Surprising as well... to the point that it looked suspicious.
Billy confirmed that his clones also were helping a fair bit. He didn't gain any experience from them, but he would get them all at once when they began to disappear, and he got their memories.
