Time flowed like water; three days passed quietly.
Wang Lin, who possessed a mental attribute martial soul, was already able to carve the most basic Level 1 soul guide array by the second day, guided by the siblings Xiao Hongchen and Meng Hongchen.
After two days of familiarization, in the evening, at the desk in Dormitory 3011.
Wang Lin held a finger-sized piece of soul tool metal in his left hand and a pink-blue carving knife in his right.
Shua.
The carving knife moved across the surface of the soul tool metal, leaving a straight path. The blade flipped under Wang Lin's control, and the line began to turn.
Wang Lin's gray eyes were extremely focused at this moment. Not just Wang Lin himself, but a white-robed old man floating in mid-air beside him was completely still in mid-air.
As if a single movement would disturb Wang Lin.
"Phew!"
The blade moved away from the soul tool metal. Wang Lin gently blew on it, and the metal shavings on the soul tool metal were blown away.
A complete Level 1 Magnetic Soul Guide Array appeared on the surface of the soul tool metal.
"Completed."
Wang Lin breathed a sigh of relief. The white-robed old man beside him, who was like a frozen frame, came alive, floating up and down. The aged voice rang out in Wang Lin's ear.
"Little Linzi, can this little gadget in your hand really change the future of this world?"
"Of course, Elder Yi. Don't underestimate this small soul guide array. I can guarantee that this small soul guide array will be the most important link in human history because it represents wisdom, the wisdom I brought from another world."
Wang Lin held up the soul tool metal carved with the magnetic array. Soul power surged, flowing into the soul tool metal from his hand. A faint white light immediately lit up within the patterns.
Clap!
Wang Lin raised his hand and approached the edge of the bed. He released his grip, and the entire soul tool metal adhered to the iron bed edge.
"It worked."
Wang Lin looked at the soul tool metal adhered to the bed edge, excitement showing on his face.
"Yours won't work, Little Linzi." Electrolux beside him shook his head at this moment. Wang Lin had thoroughly explained the complete principle of the electric motor to him over the past two days.
In Wang Lin's words, this was an exchange: he taught Wang Lin necromancy magic, and Wang Lin taught him the supreme way of physics.
So Electrolux instantly saw the problem. "According to your explanation, that electromagnet has magnetic force when energized, and the magnetic force disappears when the power is cut off. But yours doesn't have a similar property."
Saying this, Electrolux pointed to the soul tool metal adhered to the bed edge. Wang Lin was currently not inputting soul power into it, yet the soul tool metal was still firmly stuck to the bed edge.
"Ah."
Wang Lin also reacted at this moment, a hint of helplessness flashing in his eyes. "It seems I can only go with the soul power-to-electricity model."
Although the dream of a Soul Motor might not be realized, Wang Lin was not discouraged. It was just a little more troublesome to use an electric motor.
A small problem. The law of electromagnetic induction existed in this world; Wang Lin had verified this over the past two days by finding objects.
"That's wrong, Little Linzi. You yourself said that the soul guide technology in this world is already very advanced. You just started learning soul tools; how can you be sure that the soul guide technology in this world has no solution?"
Electrolux stroked his beard. In the past two days, besides staying by Wang Lin's side, he most enjoyed floating around the Sun Moon Royal Soul Engineering Academy.
Soul guide technology gave this old man a considerable shock, no less than the supreme ways of physics and chemistry Wang Lin spoke of.
"You're right." Wang Lin nodded. He was indeed shallow. After all, he had just started learning soul tools, and he was currently only dealing with Level 1 soul guide arrays.
He still needed to study soul tools properly.
"Good that you know."
Electrolux nodded and reached out to pat Wang Lin's head.
"Now that this matter is done, shouldn't you choose one of the three sets of secondary magic? And the Green Wind Condensed Gold should also be taken out."
Wang Lin, whose head was patted by Electrolux, scratched his head. He recalled the information about the three sets of secondary necromancy magic in his mind while taking out the Dark Azure Dragon.
The three sets of secondary necromancy magic were Blood, Bone, and Soul, simply speaking, refining Blood, Bone, and Soul.
Turning the blood of life into a Blood Artifact, refining the bones of all things into a Bone Artifact, and sacrificing the souls of all spirits into a Soul Artifact. Secondary necromancy magic cultivated using blood, bones, and souls respectively.
They were all somewhat anti-human. This was also the reason Wang Lin had not made a choice yet. Among the three, Blood and Soul were quite anti-human.
Blood required the blood of a creature that had been dead for no more than half an hour at the minimum requirement. Soul was even more perverse; it had to be a living creature because the dead have no soul.
Only the Bone Artifact seemed somewhat normal. Refining bones with fire had no special requirements for the bone; any bone would do.
Based on the introduction alone, choosing the Soul Artifact seemed best, as souls were ethereal and attacks were hard to guard against.
But these three sets of secondary necromancy magic all resulted in external objects. After a brief contemplation, Wang Lin finally made his decision.
"I choose Bone."
Compared to Blood and Soul, Bone was also easier for Wang Lin to cultivate at the current stage. Refining bones with fire had no requirements for the bone.
Any bone would do. Wang Lin was currently in the academy. Fresh blood and souls were hard to find, but were bones hard to find?
There were plenty of chicken bones and pork bones in the canteen; he could easily bring them out during meals.
"A good choice."
Electrolux nodded in praise, raising his hand to point at Wang Lin's brow. The three marks that had previously merged into his brow—the blood drop, the pure white leg bone, and the ghost—flew out immediately.
The three strange marks circled and floated around Electrolux. Invisible gray flowing light flew out from Electrolux and landed on the three marks.
Shua!
Light halos circulated. The three marks shed a layer of light and transformed their appearance, as if shedding skin.
The blood drop transformed into a large gray bowl, the pure white leg bone transformed into a strange azure-green flame, and the ghost transformed into a small, pure white banner.
Of the three marks, only that strange azure-green flame remained; the other two disappeared quietly into Electrolux's body.
"Do not resist."
The azure-green flame mark floated toward Wang Lin under Electrolux's control, quietly merging into Wang Lin's brow. The name of that azure-green flame also appeared in Wang Lin's mind.
Bone Refining Fire!
What a plain name. Along with this name were two sets of the most basic necromancy magic. One was this Bone Refining Fire, and the other was Bone Control.
They were clearly complementary to Bone Refining Fire.
The most important thing was that this necromancy magic could grow.
"Good magic. Thank you, Elder Yi."
Feeling the extraordinary nature of the necromancy magic in his mind, Wang Lin spoke and handed the taken out Dark Azure Dragon to Electrolux.
"Since you chose Bone, you will have to solve the problem of this Dark Azure Dragon yourself. You must do your own thing."
