"Skill Upgrade Card?"
"That's right, Master, a Skill Upgrade Card can ignore Experience Point requirements and directly upgrade a skill.
Moreover, Skill Upgrade Cards can potentially be obtained through certain special villainous acts, item refreshes, and Epic Lottery draws," the System said.
"And based on this nature, Master, you should know when it's most cost-effective to use this card, right?"
"Probably from level 4 to level 5, the max level, since the Experience Points required are the highest compared to the previous levels.
Speaking of which, even passive skills and ultimate moves can be upgraded to level five… I thought passive skills couldn't be upgraded or ultimate moves could only be upgraded to three levels," Wang Chong murmured.
"Hmm, it's not just about levels 4 to 5, but also the skills themselves.
You should know that not all skills require the same amount of points to upgrade at the same level.
Skills also have their strengths and weaknesses; the rarer and more powerful a skill, the more Experience Points it will cost to upgrade.
So, Master, if you have a Skill Upgrade Card, you can choose to prioritize upgrading the skill that costs the most Experience Points," the System suggested.
"Generally, that's true, but sometimes special circumstances require special treatment.
Using this skill card at the right time can sometimes also be a means of turning the tide," Wang Chong then said.
"First, exchange 1,000 Experience Points for me.
I want to unlock Nigth Heaven Assassination Technique and Desolate Earth, these two skills primarily based on black mist and Ruinous Power.
Then, I'll save another 500 to unlock By My Order, to unlock the ability to create wraiths and black mist.
This way, even without Experience Points, I can gradually increase the level of this basic ability, Ruinous Power, by continuously expanding the number of wraiths or continuously absorbing spiritual vein magic to create a large amount of black mist."
"Yes, Master.
You have exchanged 1,000 Experience Points.
You have 80 Villain Points remaining.
You have successfully unlocked the skills Nigth Heaven Assassination Technique and Desolate Earth," the System said.
"I've become a pauper all of a sudden, with only a pitiful 80 Villain Points left," Wang Chong said, shaking his head.
"Teacher, I've finished eating." At this moment, Sakura Matou had finished her breakfast and looked at Wang Chong with some anticipation in her eyes.
"Since Sakura has finished, let's focus on teaching first.
I'll slowly figure out the System stuff later." Wang Chong thought to himself, then stood up and led Sakura Matou to the basement.
Hm? Don't misunderstand, Wang Chong has no fondness for worms; it's just that the old worm's magic workshop was built down there and connected to the spiritual pulse.
So the basement was the most magic-rich place in the entire Matou Family, very suitable for cultivating magic.
And after a period of digestion, Wang Chong's mind was no longer so muddled, and his understanding of Nigth Heaven Assassination Technique had indeed undergone tremendous changes.
Although he didn't have the imaginary element attribute and couldn't use Nigth Heaven Assassination Technique, if anyone dared to use Nigth Heaven Assassination Technique in front of Wang Chong, they would probably be beaten so badly their mother wouldn't recognize them.
Upon arriving in the basement, Wang Chong first used Ruinous Power to connect with the magic in the earth veins, guiding it to establish a connection with Sakura Matou's magic circuit.
Then, he patiently told Sakura Matou the incantations and how to operate the magic.
Under the immense magical power, Sakura Matou learned Nigth Heaven Assassination Technique very quickly and could already easily open imaginary spaces.
This was unexpected for Wang Chong; she only took an hour to Master Nigth Heaven Assassination Technique to such an extent.
He didn't know if it was because his teaching was effective, triggering a learning buff, or because Sakura Matou was inherently intelligent.
Or perhaps it was the effect of being under the blessing of a large amount of magical power.
But no matter which possibility, it couldn't change the fact that Sakura Matou already possessed the preliminary demeanor of an Imaginary Queen.
Watching Sakura Matou's eyes filled with wonder, the imaginary space cracks appeared everywhere under her command, easily causing destruction to the surroundings: shattered platforms, walls, and even stairs.
However, Sakura Matou showed no alarm at her creations; on the contrary, her small purple eyes were filled with excitement and happiness, playing very happily.
Speaking of which, if Wang Chong remembered correctly, under normal growth, Sakura Matou would turn into a somewhat impish personality like BB-chan.
Now, seeing Sakura Matou's excited look while demolishing the place, there was a slight shadow of a little devil.
"Clap, clap." Wang Chong clapped his hands.
Sakura Matou, hearing the sound, immediately stopped and obediently closed the cracks, softly saying, "Teacher."
"You did very well, Sakura.
You have a great talent for imaginary magic.
To Master imaginary magic to this extent in such a short time, your aptitude truly makes me look at you in a new light." Wang Chong stroked Sakura Matou's head, and Sakura Matou happily squinted her eyes, enjoying the head pat.
"However, next time, try not to cause so much destruction.
It's very troublesome for Teacher to clean up." Then, Wang Chong changed his tone and pointed at the series of destructions Sakura Matou had just caused with her imaginary magic.
"Wuwu, I'm sorry, Teacher.
Sakura didn't mean to." Sakura Matou saw the destruction she had caused.
When she first started messing around, she hadn't thought much about it, only feeling very happy and interesting.
But now, Sakura Matou realized she had caused a lot of trouble for Teacher.
Looking at Sakura Matou's downcast and wronged expression, Wang Chong's eyes darted around, wanting to tease Sakura Matou a little, so he pretended to be serious and scared her, "If this happens again, Teacher won't teach you or care for you anymore, and I'll send you back to that old man!"
"Wuwu! Sakura won't dare again, Teacher, please don't abandon Sakura." As if some unpleasant shadow had been touched, Sakura Matou trembled all over, her eyes already brimming with tears, looking very scared.
"Alright, Sakura, be good, don't cry, don't cry.
Teacher was just joking with you." Seeing Sakura Matou cry because of him, Wang Chong quickly comforted her.
It seemed that even though Sakura Matou hadn't undergone Matou Zouken's physical Renovation yet, it still had a deep shadowy impact on Sakura Matou.
"Re… really?" Sakura Matou said, wiping away her tears with her hand.
"Of course it's true, my cute Sakura.
I couldn't bear to hand over such a cute Sakura to that smelly old man." Wang Chong rubbed Sakura Matou's soft little cheek, somewhat regretting making such a joke with Sakura Matou.
"Pfft… Hmm, I understand, Teacher.
Sakura won't cry anymore." Sakura Matou burst into tears and laughter at Wang Chong's "smelly old man" comment, her bright eyes reflecting Wang Chong's figure.
"It's only the first day, and Sakura has already regained some smiles.
Perhaps this is the child's true nature.
Staying in an environment like the Matou Family suppressed her personality, eventually turning her into that weak, compromising Sakura Matou who didn't even dare to easily express her feelings.
However, if Sakura's true nature is too relaxed, that little devil personality can also be a headache.
Raising a child is indeed not an easy task," Wang Chong mused silently.
For Wang Chong, who possessed Ruinous Power, making the current Sakura Matou an obedient doll was simply a matter of snapping his fingers.
However, he didn't like doing that.
He preferred Sakura Matou to slowly grow into something close to his ideal under his guidance.
He could allow for some minor accidents and deviations, as long as the general direction aligned with his own.
Therefore, Wang Chong only strengthened Sakura Matou's dependence and loyalty to him, without overly affecting her mind or personality.
He wanted to slowly cultivate his relationship with Sakura Matou.
In a sense, Wang Chong quite enjoyed this kind of nurturing play.
Subsequently, Wang Chong looked at the damaged area around them, waved his hand, and a large amount of black mist appeared from his hand.
He used his power to fully repair the broken places.
Sakura Matou, seeing this, stared unblinkingly at the black mist swirling around, mending the broken areas.
Sakura Matou no longer feared the black mist as she did last night, because Sakura Matou knew that this black mist came from her Teacher's hand, and after the black mist entered her body last night, she felt all the accumulated stress and fatigue of these past days dissipate completely.
She even had a wonderful sleep, bringing her a sense of security she had never experienced before.
So now, Sakura Matou not only didn't reject the black mist but, on the contrary, showed great affection for it.
