Inscribing Spell Seed isn't too difficult, as it's similar to casting spells. Li Xingkong has already mastered these spells, so inscribing them on others isn't a problem for him.
Compared to casting spells yourself, inscribing spells for others requires an extra step: adding the method of casting the spell to them.
It's like installing software on a computer and then putting a shortcut icon on the desktop; without the shortcut icon, the user can't use the spell.
If it's on a computer, we can search through the folders and maybe find the location of the spell. But if it's inside the human body, without the ability to see inside, we can't search for it.
The initiation for casting a spell is also very simple: make a hand gesture and add the corresponding incantation. These are the necessary conditions for casting a spell.
The method of releasing magic is so complicated, partly because it is influenced by the images of gods and humans releasing magic in traditional the Myth. They would often make hand seals and utter a spell, and the magic would be released.
On the other hand, if it's just a mantra, it's easy to accidentally trigger it. If you say it in your sleep and the spell is automatically activated, that would be bad luck.
These two spells are fine as long as they're just protective and healing spells, but if they were offensive spells, wouldn't that be like killing someone in their sleep?
It can only be said that the combination of multiple conditions forms the safety mechanism of the spell.
As for why Li Xingkong himself didn't need it, that relates to his cultivation.
In addition to cultivating the physical body, spiritual cultivation also requires a high level of spiritual cultivation.
Ordinary people have too many distracting thoughts. Sometimes when we're walking down the street, we see a street lamp and want to kick it, or we see our boss and want to slap him.
For an ordinary person, thinking this way is perfectly fine; it's just a thought, and it won't actually cause any problems.
However, once you embark on spiritual practice, these distracting thoughts become somewhat dangerous.
When you first acquire Spiritual Qi energy and magical Magic Power, you can use it almost as easily as you would your own limbs. However, since Magic Power and Spiritual Qi are not innate, there is still a long period of adjustment. When we were young, it took us quite a while to master learning to roll over and walk.
Before you've mastered it, it's easy to have problems controlling your body. For example, you might run with the wrong foot or have an uncoordinated upper and lower body when performing complex movements. These issues can all affect you.
When it comes to these basic physical actions, if you're not skilled at controlling them, the worst that can happen is that you hurt yourself. But when it comes to Magic Power, it can be very dangerous.
Take Sword Qi as an example. If Li Xingkong couldn't control his distracting thoughts, and one day he was walking on the street, he might think, "If I were to unleash a sword strike, could this Sword Qi cut down all the buildings in this area?"
Normally, this is just a thought, but if it's not controlled properly, and the thought actually materializes, it could very well unleash Magic Power and directly unleash such a Sword Qi.
That wouldn't just mean a building was cut down; the entire street's inhabitants would be split in two.
That's why it's more difficult for anime/manga fans to cultivate immortality; their fantasies are just too extreme.
Today it's your wife, tomorrow it's the end of the world. If you actually had that kind of power, whether consciously or unconsciously, you'd inevitably mess things up sooner or later.
The spell wasn't drawn out for long either; it was done in a short while, and neither of them even felt it.
Everything seems so unreal.
"It's all set, you can try it now."
Li Xingkong withdrew his Spiritual Qi and woke the two of them.
Upon hearing Li Xingkong's voice, Wu Ting and Tang Cheng opened their eyes, stood up, and focused their attention on sensing their internal bodies, but they didn't seem to find anything particularly unusual.
"Your current Magic Power is insufficient; each of you can only attempt one spell at most."
Li Xingkong had spoken to them beforehand to prevent them from getting so carried away that they drained themselves dry.
"How do I use this spell?"
There were no instructions, nor any explanations forced into their minds; even with the spells, the two still didn't know how to use them.
"First is the Rejuvenation Technique, which requires reciting 'All things return to spring' and then forming a Dao Finger with your hands."
Li Xingkong made a hand gesture, the so-called "Dao Finger," which means raising the index and little fingers while clenching the other fingers.
Tang Cheng arrived first; once he became interested in something, he always wanted to be the first to do it. He stood in front of Wu Ting, formed a hand seal, and murmured, "All things return to spring."
Then the spell began to be cast.
He felt the Magic Power that had been flowing through his body gather in his guiding hand. As the Magic Power gathered, it felt as if a straw had been inserted into his body, and all his strength was being drained away.
A faint Magic Power mark appeared on the finger of the guide, emitting a faint white light.
He raised his hand and stroked Wu Ting's body; wherever his fingers touched, Wu Ting's skin noticeably paled.
It wasn't that he was too dirty and they cleaned him up, but rather that new skin grew where they touched him, making his skin look much whiter than it had been after being in the sun for several days.
Unfortunately, Tang Cheng's Magic Power was too low. In less than 5 seconds, Wu Ting only had a white trail of about ten centimeters on his hand before the Magic Power mark on Tang Cheng's hand flashed twice and disappeared.
It was indeed effective, but the effect was too short-lived.
If he continues to force it, it won't just deplete his Magic Power, but his physical strength.
"Amazing! I can use magic now!"
Although he was already sitting on the ground, the joy in Tang Cheng's eyes was clearly visible. This was magic, and he had never thought in his life that he would be able to cast spells.
"Coo coo coo"
Just as he was still laughing like a child, his stomach started acting up.
That attack not only drained his Magic Power but also consumed a lot of his physical energy. Now he's like someone who hasn't eaten for three days; if he delays any longer, he'll become malnourished.
Li Xingkong found two energy bars and stuffed them into his mouth. He had originally wanted to say something, but now he could only make a series of whimpering sounds.
"Then I'll try another one."
As the recipient of the spell, Wu Ting personally experienced the effects of the Rejuvenation Technique. He could only conclude that the effect was not fake or an illusion, but truly real.
There was another spell he wanted to try out on the spot.
"The other spell is called Explosive Counter Spell, a protective spell. To cast it, place one hand in front of your chest, and the incantation is 'Shield, come!'"
As for where this incantation came from, Li Xingkong said that he just came up with it randomly. Anyway, he was the one who carved the spell, so he could decide what the activation incantation was.
Protective spells are usually used in emergencies, so the incantation should be as simple as possible to avoid accidents happening before the incantation is finished.
