Every day at 3 p.m., in Professor Cook's lab, Marina would spare an hour and a half to teach Donald.

The whole teaching process lasts two weeks, and as long as there is nothing to attend to on both sides, then the teaching does not stop even on holidays.

In return, Donald needed to serve 3 more servings of the previous dish, with quality and quantity.

This is the result of discussions between the two sides, and Donald is happy with it, and it is now August 11th, which is less than three weeks before the September Abnormal Bureau of Investigation that Gonitz said will find someone, and it is just right to maintain this time.

After a few hours of inscription scroll production that night, Donald looked at a bottle of moonlight ink that was almost bottoming out, for such a long time, the wolfhound inscription scroll was still only 1 piece completed, and the rest of the level 1 inscription scrolls were only made 3 sheets.

Call~

Falling back in the chair and breathing a long sigh of relief, the consumption of mental power made Donald inevitably feel tired, looking at the moon outside the window, and Finger, who was lying on the window and shrouded in moonlight, turned his head to look at the time on the wall.

Half past ten in the evening.

Putting the scroll away in the bag next to him, Donald picked up the coat hanging behind the chair and quietly left the room.

The Royal Delorraine House is a large house, with gardens and other places for the students' daily leisure activities, and the location is concentrated in the southeastern corner of the Royal DeLorean Academy, which is the most recent place for Donald to find a spell practice, after 10 p.m., of course.

I found a relatively remote place in the garden, where there were still some fallen leaves and dust on the benches, and it looked like a place where no one usually comes.

After confirming that there was no one around, Donald took out the bone spirit disk and released the toad soul that had just been absorbed today, and he had to figure out how far this guy's actions could go.

Sitting on the bench, he looked at the toad in front of him, which was obviously several circles smaller than the original size, and recalled the scene when he fought against it before.

Among them, Donald valued the toad's sonic attack, even he couldn't defend well at that time, relying on the invisible slave who would act autonomously as long as he gave an order, and the others didn't have a pair of energy hands that could act on their own in the face of this skill.

The toad lying on the grass opened its mouth and turned to a nearby bush, Donald picked up his notes and prepared to record some data, but there was no follow-up.

"Not working?"

Donald stood up with his note in his hand, and the toad opened its mouth and turned to the goal it had set, proving that it was responsive to its commands, but unable to speak.

"It can't be because you don't have physical vocal cords, so you can't make a sound...... In the soul state, it can also affect the vibration of the air, there is no question of whether there are vocal cords or not, and my command is not strong enough?"

The cap of the pen propped up his chin, and Donald walked in circles around the toad, pondering the problem.

The attempted enhancement command unsurprisingly failed, the Bone Spirit Disk was an independent curiosity, and all Donald needed to do was activate it, and then summon the souls contained in it by consuming mental power, strictly speaking, it was the same as a game he had played in his previous life.

It's as simple as capturing pets and fighting by giving orders after they are released, but the premise of capturing "pets" to him is to kill the other party first.

Kill in the truest sense of the word.

Since the frog song can't be used, let's attack with a different tongue, and this time it was immediately responded, and the tongue in the toad's mouth rushed out after 3 seconds of charging, directly hitting a bush of wildflowers 5 meters away, entangled it and dragged it back under Donald's order.

Immediately afterwards, Donald tried to jump and kill, but it was still easy to succeed, except for the frog song.

In addition to this, Donald also noticed that all of Toad's attack strength had decreased, and the gap with the main body was not half a star, but close to a 3% weakening.

"It seems that you still have to ask a professional...... Hannibal, come out. ”

If it is the Bone Spirit Disc that causes the sonic attack to be unusable, then there is no guarantee that the same situation will not occur in the future, Donald doesn't want the souls he received to end up being a group of soul bodies that can only use superficial attacks or use as meat shields.

The pain in his finger was as high as ever, and Donald always felt that if he could take the ring off at any time, a piece of white bone would appear under the ring.

"Why did I use the Bone Spirit Disk to collect the soul of a toad beast, when I re-summoned it, its abilities in all aspects declined, not to mention, there is one ability that I value the most is simply unusable...... How much qi and blood does this question need to consume?"

After saying his question, Donald still asked a specific question.

"Do you just want me to answer this, or do you want me to tell you all the secrets of the Bone Spirit Plate?"

"That's it for now, by the way, can I delay the payment, and I'll pay the blood when I get back to the room, I don't want to fall in the garden. ”

"The compensation is similar to parchment, with your current physical state, that is, a mental coma within a few hours, as for the delay in paying the price, it is acceptable in a short time, do you need to answer?"

"Say it. ”

Although Donald didn't like the feeling of waking up with a sore back, the function of the Bone Spirit Disk had to be figured out as soon as possible, and this strange object was the only thing he could use in battle at the moment.

"Its soul is too weak, you need to feed it with energy, just like feeding a beast, it is stripped from the original body by the bone spirit disk, this is a great loss, if you don't want to replenish it, it can play to this extent, the more you feed, the easier it is to return to the original state, so the above is the answer, and then I will remind you that the function of this bone spirit disk is more than this, if you want to know more, you can continue to ask me when you have the opportunity, anytime, anywhere, quack~"

Doctor Meat-Eater didn't revert to the Ring this time, waiting for Donald to pay.

"Energy, that's a coincidence......"

Donald looked at the siphon bone ring on the middle finger next to the Flesh-Eating Doctor, a ring from Rastolle that absorbs and stores energy.

Standing in front of the toad, the energy absorbed from its body was re-released, and a cloud of jelly-like viscous liquid poured out of the surface of the siphon bone ring as if squeezing foam.

Command the toad to devour these energies through the Bone Spirit Disk.

The silent toad opened its mouth and bit on these energy liquids, like eating meat, its sharp teeth cut the energy, and swallowed it in a big gulp, and after these energies entered the soul, they turned into nothingness for the first time, not disappearing, but being digested by the soul body.

Under Donald's gaze, the toad's body quickly grew significantly, and the originally somewhat illusory and transparent figure also condensed a lot.

By the time it has devoured all the energy belonging to its body in the ring, its body size is still a little worse than the original body, 3% smaller than before, and now it is only one size smaller.

Again designate a target bush and frog chirping!

Wail~

Targeted sonic attack, Donald stands next to the toad half a head shorter than himself, and can easily see the sound waves vibrating in the air, and the scene of the targeted bushes shattering in an instant!

"Very good, very good, Rastolle probably didn't expect that this gift gave me two sets of strange things, with a siphon bone ring to extract energy, so I don't have to worry about not being able to recover my strong soul. ”

In Donald's eyes, the Bone Spirit Disk is like a Poke Ball ball, and it is also a functionally enhanced version, and a ball can hold a lot of elves.

"You're the first right-hand soul I've subdued, how about changing your name to Sonic Toad......? You'll have to work hard in the future. ”

Donald stared at the sonic toad, who had no emotions or movements, and said to himself, he was in a good mood.

Just as he was about to retract it from the Bone Spirit Disk, he raised his hand and put it back again, when Donald suddenly thought of another way to strengthen the sonic toad.

That's right, it's demon activation!

He used to experiment with some dead things, and the things that were activated were nondescript, with no useful functions and no strong combat effectiveness, but this sonic toad was different, although it was a dead thing, it was the same nature as an invisible slave, and it could accept its own orders to make corresponding moves, and after activating it with demons, was it a new world?

With one hand, stroking the sonic toad's swollen forelimbs, a dark green flame rose from Donald's emerald green pupils, and the next second, dark green lines of fire poured out of his hands.

The entire body of the sonic toad instantly grew explosively, this time directly surpassing Donald's size, and the muscles on his body swelled strangely, and the whole body turned from pale green in the soul state to pitch black, and finally cracked dark green cracks because of the line of fire, its eyes were dyed blood red, and a black linear pupil appeared in the center.

Weird and evil!

This is not just the end, while completing the physical change, Donald's mental power consumption is close to 3, he does not stop, but continues to output his spiritual power with all his might, he wants to see what the demon activation can turn this sonic toad into!

The mental power consumption was close to 6, and on the two eye sockets on the top of the sonic toad's head, black cuticles suddenly began to appear, like two blades appearing on the top of its head.

The mental power consumption was close to 9, and two narrow whiskers began to appear on the left and right sides of the two nostrils of the sonic toad, like octopus tentacles, flying and shaking in the sky.

No, Donald fell back on the lawn a little helplessly, blood was constantly flowing out of his nostrils, and he didn't dare to output his mental power again.

The previous inscription scroll had consumed a part of his spiritual power, which was already overdrawn to strengthen his spiritual power.

Interestingly, even after this point of strengthening, Donald already felt his absolute control over the Sonic Toad, and according to the ability of the Bone Spirit Disk, the powerful soul was actually in danger of getting out of control.

As long as it is something with its own spiritual power, then it can be controlled?

Donald realized that he might have discovered some of his gifted abilities.

A whim-struck attempt, killing two birds with one stone!

"Hey, at this level, I really want to let you go out and fight with people!"

Donald grinned, his left hand supported the lawn, and his right hand was raised diagonally upward, and the sonic toad immediately turned around, leaned down, and took the initiative to hand his forehead under Donald's palm, Donald's figure was reflected in his scarlet eyes, and a soft frog croaking sound came out of his mouth.

It is paying the highest tribute to the existence that created itself.
