I built a floating city in the game.

"The constituent units of a spell model are not spell nodes or mana channels!"

Mo Bai did not complete all the group experiments, but after finding the pattern, he directly verified it using sampling experiments.

"There's another layer between the spell model and the spell node!"

"This can be called a spell structure."

Mo Bai excitedly made notes in the forum's drafts folder.

"Spell nodes and magic pathways make up spell structures, and different spell structures have different functions."

Finally, all these magical structures constitute the complete spell model. Cast the spell!

After completing all the verifications, Mo Bai immediately retrieved the last large, complete wolf king pelt.

The piece of paper was the size of an A3 sheet of paper. Without any hesitation, he quickly began to write on it.

"One, two, three... ten... fifteen!"

In the blink of an eye, fifteen spell nodes fell, quickly connecting one magical pathway after another.

Ten magical pathways were used in succession without causing any change in the magical power; the magical power simply became more turbulent.

"Yes, yes, yes, that's right, that's exactly it."

Mo Bai looked at the stable magic channel and a slight smile appeared on his lips.

"This Wind Blade Technique model has three components."

The first one should be... constraint!

Mo Bai drew a magical pathway, and the five magical nodes in this small area immediately connected to form a small whole. Magic flowed and changes occurred within it, but no abnormalities occurred.

"The second structure should be... wind!"

He stared at the magical structure that had just caused him to be blown away countless times.

This structure consists of seven magical nodes. The moment the last magical channel was formed, the magical power surged and crashed, with a faint howling wind. Mo Bai subconsciously dodged, but the magical power did not turn into wind and blow out.

"Just as I thought!"

Mo Bai watched as the magic transformed into a whirlwind and was then restrained into wind blades, slowly rising and falling, appearing and disappearing.

"This order is indeed correct. Next is the final step... magic infusion!"

Exhausted, Mo Bai opened his eyes wide, which were already bloodshot, but he ignored them and focused intently on controlling the brush in his hand to bring it down.

"Buzz!"

With the final stroke completed, the magical pathways of the entire spell model were fully opened, and all the magic in the animal hide flowed into the spell model. Afterward, a faint vortex appeared, and magic that appeared out of thin air poured into it.

Silently, the entire wolf king pelt seemed to grow thicker, and the traces of wolf king blood on it turned into dark red ink marks, as if it had undergone a long period of time and become faintly ancient.

However, Mo Bai was unable to witness this scene. After forcing himself to finish the last stroke, he felt dizzy and his brain felt as if it had been emptied and then cleaved open by an axe. He collapsed to the ground and lost consciousness.

When Mo Bai woke up again, it was already broad daylight.

He slowly got up, supporting his throbbing, convulsing brain.

"My head... Did someone hit me?"

Mo Bai shook his head, gradually recalling what happened before he lost consciousness.

"Oh right, my spell model!"

He realized what was happening and immediately looked at the animal hide in front of him.

At this moment, the wolf king's skin, which was originally bloody, now looked as if it had been kneaded and smoothed out.

The thick, rustic animal hide is like a sheet of rice paper, upon which a beautiful dark red model is drawn.

What's truly captivating is the magic that flows according to certain rules.

The magic flows and influences each other, eventually causing a qualitative change in the magic, which transforms into an invisible wind blade that floats within it.

Mo Bai had an idea.

With just a thought, the wind blade seemed to fly out guided by his mind.

More importantly, the magic within this spell model did not dissipate over time.

It even slowly absorbs the magic in the environment to maintain its own existence.

"It's done!"

Mo Bai's lips curled up slightly.

"Hahahaha! I did it!"

"Spell Scroll!"

"I did it!!"

He was overwhelmed by intense excitement and a sense of accomplishment, and it took him a long time to recover.

"I'm awesome."

Looking at this spell scroll, Mo Bai still couldn't help but sigh.

He carefully rolled up the spell scroll and put it away. Turning to look at the remaining animal hides and wolf blood, his emotions calmed down, and he felt a pang of heartache.

"What a pity, all the magic has dissipated."

"However, there's nothing I can do about insufficient mental energy; I simply can't use it all up before it dissipates."

"But it's already very good that we managed to get one."

However, a considerable amount of magic remained within these wolf bones.

Mo Bai rubbed his temples; his brain was still throbbing with pain from excessive mental exertion.

"The bones should last another ten days to two weeks, let's keep them for now."

It can probably also be used as a deterrent; with this, most wild animals wouldn't dare approach me.

After carefully collecting the wolf king bones, the wolf king hide (which had lost all its magic power), and the wolf king blood, Mo Bai continued walking forward.

Instead of going any deeper, they followed the sound of water and found a lake to the side.

Looking at the tranquil lake, Mo Bai felt refreshed and relaxed. Beside the lake were cliffs, and around the bend was a cave.

"What a great place."

"Okay, we'll stay here. It'll keep us from the wind and rain."

Mo Bai walked into the cave with great joy. The cave was seven or eight meters deep, empty and quite flat. He immediately got to work.

With his mental energy depleted and injured, even the slightest attempt caused him a headache, so Mo Bai didn't dare continue the experiment and simply took care of miscellaneous tasks.

They cut down trees to make walls, and soon sealed off a small space at the bottom of the cave. They laid out a small bed, made a fire pit, and roasted a piece of wolf meat.

"Seriously, why didn't I experience any reaction after eating this magical meat?"

Mo Bai ate another piece of wolf king meat, muttering something under his breath.

He then shook his head, entered the cave, lay down on the wooden bed, and fell into a deep sleep.

When he woke up again, it was completely dark.

Only then did Mo Bai's mental strength fully recover.

"call."

"The mental exhaustion is awful, but it seems like my mental strength has increased a little?"

He tried to feel the magic and immediately found that his perception of it had indeed become much clearer.

"Can you train your mental strength by using up all your mental energy and then recovering it?"

"Can you get stronger without adding any points?"

Mo Bai was slightly surprised and couldn't help but open the attribute panel to take a look. He confirmed that his mental strength attribute was still twelve points, and that his mental strength had indeed been strengthened through training.

But then he suddenly realized...

"Huh? How did my experience points increase?"

Experience points: 146/300.

"It was clearly 137 originally, and nine points were added! But I didn't kill any monsters."

Mo Bai immediately opened the system prompt page to check.

Upon opening, the first system notification immediately came into view.

"Experience points +9".

Looking at the time, he was surprised to find that it was the time when his mental strength had fully recovered.

"So... you can gain experience by training your mental strength?"

"What about physical training?"

Mo Bai couldn't help but fall into deep thought.

"A second upgrade method? Are there any differences between the two upgrade methods?"

Is it one kind of gain without effort, obtained out of thin air, and the other kind of gain through solid training and gradual accumulation?

"Training, or leveling up by fighting monsters?"
