Su Muyu had also reached Level 8, and her Perception had increased to 19 points.
The average attribute of a normal adult in five dimensions is 10 points, so 19 points of Perception is a very high number.
Moreover, at this point in time, there weren't many Superpower Users who had reached this level.
Among the three Demon Crystal Cores obtained from hunting the Abyss Tide Worm, apart from "Corrosive Mucus," there was also a Skill Crystal Core for "Prism Tower Shield."
"Prism Tower Shield: Release energy to form a prism-shaped tower shield, blocking attacks. Skill Duration: 3 seconds. Skill Consumption: 20 points of Source Energy. Skill Level: D Level."
This was a Defense Skill, a D-level skill with C-level defense power, but it required high technical skill from the caster.
The advantage was its high defense power, but the disadvantage was also clear: the duration was quite short, lasting only 3 seconds.
In other words, one could not pre-emptively activate this skill and then charge into a fight.
The skill needed to be used in the instant an attack occurred in order to be effective.
Of course, one could also predict an attack within the next 3 seconds and use the skill in advance.
Either way of using the skill placed high demands on the caster.
If it were someone else, Heng might not be confident, but Su Muyu would definitely have no problem.
More importantly, "Prism Tower Shield" could link with the "Reconnaissance Eagle," making it a very strong combination skill when used well.
Therefore, Heng decided to have her learn this skill.
"Learn this skill."
"Alright." Su Muyu crushed the crystal core, absorbed the energy of the crystal core, and learned the new skill.
She first tried it out, then began to slowly study the skill effect.
She had her own understanding of skills and sometimes she didn't need Heng's instruction to figure out how to use them.
"Um... this skill seems to have a bit of a high difficulty in use, and it only lasts for 3 seconds."
"Yes, that's why the timing of its use needs to be very precise," Heng nodded.
Su Muyu tested the skill again and frowned, "But this skill can only be used near the self; throwing out the shield energy, it only reaches up to one meter."
After testing it, she felt the skill's range of use was very limited.
The appearance location of the "Prism Tower Shield" could only be up to one meter away from oneself.
This meant that the skill was basically only for her own use, and could not be used to protect Heng.
After all, during a battle, it was not possible for Heng to always maintain a distance of one meter from her.
Heng smiled and reminded her, "No, this skill is indeed a close-distance defense skill for others, but for you, it can be used remotely. Do you remember the skill fusion technique I taught you?"
"Got it." Su Muyu instantly understood.
When she was on the Abyss Battlefield, she had already used the technique of skill fusion.
She had now learned three skills: "Reconnaissance Eagle," "Invisibility Veil," and "Prism Tower Shield."
Among these three skills, the one that could form a skill fusion to allow "Prism Tower Shield" to be used for remote defense was naturally "Reconnaissance Eagle."
Su Muyu pointed at the Reconnaissance Eagle in mid-air and used the "Prism Tower Shield" skill.
The energy of the Reconnaissance Eagle immediately transformed into a prism-shaped shield.
Without needing practice, the first fused use of the "Prism Tower Shield" was successful.
Heng grew even more fond of her brilliant talent, as she could learn anything with just one try.
Su Muyu began to think further, asking, "So using the Reconnaissance Eagle, can I activate any skill remotely?"
Heng nodded, "Apart from some more special skills, most can be activated remotely."
Su Muyu grew to like the Reconnaissance Eagle skill even more, "So the Reconnaissance Eagle is that amazing."
Heng reminded her, "The skill fusion effect of the Reconnaissance Eagle indeed allows many skills to be activated remotely. However, using it this way will consume the Reconnaissance Eagle, effectively increasing the Source Energy consumption."
Su Muyu nodded thoughtfully and summarized to herself, "So, skill fusion should be used in emergency situations, and energy should be conserved normally. Hmm... Is this what is called 'Control Blue'?"
"You know quite a lot."
Heng found that teaching her combat techniques was quite effortless, a slight hint and she could comprehend on her own.
Su Muyu looked at her Skill Slots, she had learned three skills already, and there were two Skill Slots left.
"Um... I still have two Skill Slots left, can I still learn Attack Skills later?"
Heng passed over the "Corrosive Mucus" Crystal Core, "Attack Skill."
"No way." Su Muyu rejected the offer with her whole being, and when she saw Heng trying to give her the crystal core, she turned and ran.
Heng chased after her with the "Corrosive Mucus" Crystal Core in hand, and the two frolicked and chased each other on the beach for a while.
Su Muyu suddenly stopped, and Heng, unable to brake in time, ended up tackling her onto the sand.
"`Actually, this skill is really useful.`"
"`I know, but I don't want it.`"
Su Muyu was aware of a skill capable of corroding metal, which was highly practical, but she couldn't stand the thought of her body secreting corrosive mucus.
Lu Heng was just teasing her. There were plenty of other ways to gain an attack skill. Even without learning a new one, it was possible to evolve an existing skill to develop attack power.
"`How far have you trained your Reconnaissance Eagle skill?`"
"`Uh, I just maxed it out last night, didn't get the chance to tell you yet.`" Su Muyu had finally reached full mastery (1000/1000) of the Reconnaissance Eagle skill the night before.
After maxing it out, she had tinkered around for quite some time but couldn't find a way to upgrade the skill.
"`That fast?`" Lu Heng was a bit surprised.
Because Lu Heng's Gale Step skill level was only at (998/1000). He hadn't expected Su Muyu to max out the proficiency of the Reconnaissance Eagle skill ahead of him.
"`Once the skill proficiency is maxed out, how do I upgrade it?`" Su Muyu had tried all sorts of methods but failed to upgrade her skill.
"`Skills are different from martial arts; mere practice won't level them up.`" A hint of amusement flickered in Lu Heng's eyes as he opened his attribute interface and glanced at his Initial Talent, "Divine Evolution."
"Divine Evolution: Use Divine Energy to fuse with and evolve skills, breaking through the skill level limits and advancing skills into a higher form."
Superpower Users couldn't upgrade a skill mastered through a Crystal Core simply by filling up its proficiency.
However, "Divine Evolution" could unlock skill locks, lift the level constraints of skills, and enable skill upgrades through the fusion with Divine Energy.
Moreover, the most powerful aspect of this Talent was that it not only allowed the evolution of one's own skills but also could help others unlock their skill locks.
Lu Heng extended his hand, saying, "`Give me your hand.`"
Su Muyu did as instructed, unsure of what was to come.
Holding her hand, Lu Heng closed his eyes, used "Divine Evolution" to unlock her skill lock, and guided, "`Now focus and try using your Divine Energy. Infuse it into the skill slot of the Reconnaissance Eagle to raise the skill level.`"
Following his instruction, Su Muyu closed her eyes and felt a subtle shift in her Reconnaissance Eagle skill, as if the lock on the skill level had been released.
She tried to channel Divine Energy into the Reconnaissance Eagle skill slot as told.
As Divine Energy merged into the skill slot, the two energies intertwined within, eventually fusing together.
The moment the fusion completed, data appeared before her eyes:
"Consumed 300 Divine Energy points, 'Reconnaissance Eagle' skill upgraded to 'Advanced Reconnaissance Hawk.'"
"Advanced Reconnaissance Hawk"
"Skill Level: C Level"
"Skill Consumption: 20 Source Energy points"
"Skill Effect: Summon an Advanced Reconnaissance Hawk capable of aerial scouting, Detecting Invisibility, and engaging in combat. Detecting Invisibility Range=2×Perception Power; Attack Damage=1×Spiritual Power."
"`Did the skill upgrade succeed?`" Lu Heng inquired about the result.
"`Mm!`"
Su Muyu nodded vigorously, "`It was successful, it turned into an Advanced Reconnaissance Hawk, and now it has the ability to attack, and the Detecting Invisibility range has doubled.`"
"`That's good.`"
For Su Muyu, the upgrade of the D level Reconnaissance Eagle to C level was significant; not only did the Detecting Invisibility range double, but it also gained attack capabilities.
From the team perspective, this skill had to be prioritized for upgrade.
Its priority was even above Lu Heng's own skills.
Lu Heng had even considered that if the first upgrade attempt failed, he would be willing to spend another 300 points of Divine Energy to ensure her Reconnaissance Eagle skill upgraded.
When Su Muyu returned from the Abyss Battlefield, she had gained a total of 900 Divine Energy points. She spent 300 on the basic Law Integration with her Energy Crystal Bracelet.
Now, having spent another 300 on skill upgrading, she had 300 left.
After reviewing the upgraded skill data, Su Muyu asked, "`The attack damage isn't linked to Perception Power but to Spiritual Power instead?`"
Lu Heng nodded and explained, "`Yes, Perception mainly enhances detection abilities, like improved vision, hearing, and more easily spotting invisible targets or hidden traps like mechanisms.`
"`Attack-related abilities are mostly associated with Spiritual Power. The stronger the Spiritual Power, the higher the damage inflicted by controlling the Reconnaissance Hawk.`"
Pondering, Su Muyu asked, "`How strong is the damage at 1×Spiritual Power?`"
"`Hmm...`" Lu Heng thought for a moment and gave an example, "`A handgun's attack power is 105, and it's a thermal weapon unaffected by Body Attributes, so its damage is pretty fixed.`
"`That means, with your current Spiritual Power, controlling the Reconnaissance Hawk to attack five times is comparable to firing one shot with a handgun.`
"`Of course, this is just a simple comparison. Actual damage depends on the area of impact.`
"`If you target a vital spot, a single strike can be lethal if it breaks through the defense.`
"`Beyond that, the Reconnaissance Hawk can also aim for specific parts of the body, like the eyes.`"
"`Pecking the eyes, that sounds a bit cruel,`" Mu Yu pursed her lips, not quite ready to accept such a method of targeting vulnerabilities.
"`You'll understand when you encounter an enemy who is ruthless," Lu Heng shook his head and chuckled, "`Kindness to an enemy is cruelty to oneself.`"
