With eight beasts in front of them, four heavy armored mountain bears, and four green windwalker bears in total

All of the bears in front of them were at the low/mid unblemished rank and the green windwalker bears possessed a strong wind affinity, turning their body slimmer, causing them to be faster, while the heavy armored mountain bears didn't have an affinity, while their constitution was comparable to heavy tanks.

While Jason decided to step back with Artemis on his shoulder, Lux summoned his small skeleton unit causing the attention to switch to him... 

One could even say that the death transmuted mana radiating from the skeletons was an advantage in this case because it forcefully attracted all bears to charge towards them.

It was as if they taunted them, causing Jason to nod in admiration before he stepped back another few steps.

'Is that their strategy?' He wondered, as he saw the nightmare horse and Malia attacking the bears with long-range elemental spells, while Jennifer did the same with her bow

Meanwhile, the Shadow panthers seemed to vanish within the surrounding shadows while Lin and his treant soulbond controlled the vines and roots all around in order to hinder the eight unblemished bears' charge towards them.

Uprooting several meter long roots that were tight wide, they coiled around the bears' legs, only to be ripped apart by the massive strength behind the bears' charge, which fortunately slowed them down by a small margin.

Meanwhile, Lux prepared himself, circulating the mana within him in order to activate his movement technique when he ordered the skeleton archer to shoot the bears' vital spots, while the warrior was supposed to stall time.

Lux and the Skeleton assassin charged forward passing the warrior and it seemed as if they were faster than the heavy armored mountain bears causing the two of them to evade their attacks easily.

Theo decided to take care of the green windwalker bears, with Jennifer and their two peak-evolved Shadow panthers' help.

Because the bears' attention was focused on the undead beings, the others had a very easy time surviving, while Malia and her nightmare horse shot dozens of fireballs one after another on a single heavy armored mountain bears, that was shaken out of the bewitching hostile feeling against the undead being in front of him, as it smelled burning flesh with searing pain passing through its whole body.

Looking down, multiple holes with burned flesh and bones sticking out could be seen, which caused the injured bear to widen its eyes as its strength slowly dissipating, when a compressed water jet pierced one of the holes within its chest.

Slowing down, the other seven bears continued to charge, while their brethren made its last steps, looking longingly at its compared that were still alive…

'Isn't she consuming too much mana?' Jason wondered as he continued to observe the whole battle, which seemed to proceed extremely weirdly.

If Jason wasn't a complete fool, it seemed like Lux didn't care a tiny bit about his soulbonds, because the Skeleton Warrior and Archer were beating up and their bone limbs ripped apart, while he focused on a single opponent with the Skeleton Assassin next to him.

However, Jason noticed something new and it seemed as if the Skeleton warrior and archer that were ripped apart didn't lose a single bit of their mana fluctuations, while their core still shone brightly, as his eyes widened.

'Are Undead beings immortal?' He wondered and the mana core with the sealed soul within had to be the reason, because of the vast mana fluctuation, held everything forceful together.

While three bears bashed up the two Skeletons, Jennifer already shot multiple arrows, injuring the bears' knees, which slowed them down, while Lin used his affinity together with his treant in order to decrease their speed further by uprooting more thick roots that coiled around their feet, chaining them up.

At the same time, Theo stood behind one of the green windwalker bears with his longsword pulled back, cleaving down, severing one limb without much obstruction, as the Shadow panthers stealthily approached the unaware bears before they pounce at them to inflicting more injuries at their already seriously injured legs.

With their legs almost completely crippled, the heavy armored mountain bears could barely do anything against the expedition team with their numerical advantage, as the green windwalker bears summoned a strong draft around them, with dozens of wind spears manifesting around them, which they shot out, without caring about anything at all.

Barely evading one wind spear that flew towards him, Jason was fortunate that he could perceive the mana fluctuation before anyone else thanks to his mana eyes.

Meanwhile, Lin´s treant was pierced by a few spears, while the others evaded or deflected the spears.

A treant could survive something like that without problems due to its exceptional regeneration ability and the whole battle ended a minute later with Theo severing the last green windwalker bear's head.

The only casualties they faced were the Skeleton warrior and archer, while they radiated their thick death transmuted mana, attracting their bones that laid all around the small battlefield.

Jason noticed a few bite marks on the bones that gathered around the Skeleton's mana core, as they were drawn back to their original position.

'Won´t their combat prowess decrease if the bite marks deepen further if they don't heal?' He wondered as he noticed the dense death mana within the Skeleton mana core enveloping the damaged bones as if they wanted to heal them.

Suddenly, he perceived tiny changes and the bone marks seem to regenerate slowly, which caused him to look at the bite marks more intently.

'Interesting!' While the others stored the bear corpses in their spatial rings, Jason continued to observe the skeletons' healing process, before he noticed Malia standing next to him.

"It's creepy, right?" She said slightly disgusted before she noticed Jason shaking his head.

"It's really interesting!! How can they heal so fast!?" He said, wondering about the fast healing process these skeletons accomplished solely through their mana core.

Lux stood not far from them and heard Jason, and what the youth said, caused him to lift his eyebrows because it was the first time for someone to say something like this when they saw his skeletons' healing process.

Most students and even teachers at his school were disgusted by this ability and they found his fighting style even cruder because he sacrificed his slower skeletons in order to finish his opponents.

However, there was not really a perfect way to use the Skeleton warrior in a better way, because its innate intelligence is restricted to the bare minimum while controlling them perfectly to allow them to use martial art techniques was too taxing.

As such he used a sacrifice tactic almost every time he fought, with the skeleton warrior as the tank, his archer as a means to slow down his opponent while he and the skeleton assassin would take care of the rest.

In addition, the constant radiating death mana would always attract the hostility of beasts, causing other tactics to be useless, as long as he didn't have enough soulbonds to take care of larger beast tides.

Jason found the tactic used by Lux, crude but efficient, as long as his soulbonds survived because undead´s couldn't feel pain which was also an important factor within the plan.

But he was more astonished about the others teamwork, as everyone focused their attacks on vital points in order to slow down the bears' charge, while the vines and roots seemingly ended the fight.

Without being able to move freely, the bears could be compared to training puppets or targets causing Jason to feel almost pity for them.
