But with the Quincy Crystal, it is different, it can conduct a certain level of high-level magical energy, but it will not conduct low-level magical energy, in Philip's successive experiments, and even later he released the seventh-level magic "Steel Armor" There is no problem.

If the energy is exchanged by the sinusoid, due to the characteristics of the sine wave, when the amplitude of the waveform is higher than the on-threshold of the Quincy crystal, the sine wave will be turned on, when the amplitude of the waveform is less than the on-threshold of the Quincy crystal, the sine wave will not be conducted, and in the process of being turned on to not being conducted, there will be energy output at both ends of the Quincy crystal, and its waveform is similar to an arc, like a small part of the peak of the sine wave.

When the whole sinusoidal alternating energy is three-phase, a sine wave of the same amplitude and the same frequency is repeated every third cycle, when one of the sine waves is turned on from conduction to non-conduction, the other sine wave will be turned on, and when it is not conducted, the third sine wave will be conducted, and when the third sine wave is not conducted, the first one will be turned on, and the reciprocating cycle will be so that the output waveform will be the waveform with a small change amplitude at the top of the sine wave, and basically the same effect as the DC waveform will be produced when acting on the object。

Thinking of this, Philip became excited.

Grace couldn't help but smile softly when he saw Philip, whose whole body was as gray and white as steel, dancing and screaming and dancing in the laboratory, the man who was focused was so cute!

After placing the three Quincy crystals neatly, Philip pulled out three Monster Crystals from an experimental three-phase magic energy machine in the laboratory and connected them to an empty magic crystal, so that the three-phase rectifier device was completed.

Then, Philip began to slowly rotate the three-phase magic energy machine, and the yellow raid magic energy was transmitted from the demonic beast tendon to the three-phase rectifier device, and what went in was the yellow energy, after passing through the output of the Quincy crystal, the yellow light became extremely dim, like a kind of white light with a little bit of yellow.

This energy with an extremely pale yellow light rushed into the empty magic crystal, Philip held his breath and watched as the magic crystal became cloudy little by little, this magic energy was like normal DC magic energy, which could charge the magic crystal!

"What is this?"

Before Philip could stop the magic machine, Grace walked to the table with the magic sword in his hand, and the glittering blue crystal instantly attracted her attention, the duchess had not opened the box at all when she delivered it.

"It's so beautiful!" Grace stretched out a hand and picked up the blue crystal, ready to put it in front of her eyes to admire, in her opinion, how could pure magical energy hurt herself who was immune to magic.

Philip secretly said that it was not good, Grace had not yet realized that the magic sword in his hand had an arconian bronze meridian, which was equivalent to her being able to feel the energy of magic now.

Philip wanted to stop Grace, but unfortunately it was too late, and before he could call out, he saw that the yellow magic energy was directly strung into Grace's body, and her whole body emitted a bright yellow light!

Quickly stopping the magic machine, Philip rushed to the experimental table to catch the duchess, who was already limp.

"How is it? are you okay?" Philip hurriedly threw away the Quincy crystal and magic sword on Grace's body, and felt it carefully, fortunately, Grace's body could not contain magical energy, the accident just now should be similar to the capacitive reaction on earth, there is an insulator between two conductors, when the voltage is too high, the charge between the conductors will break through the insulator.

Grace is the insulator, and the rectifier device and the magic sword are equivalent to two charged conductors, the magic energy in the magic sword is used up, and the other side is connected to the magic energy machine, which naturally causes a huge disparity in magical pressure, which instantly penetrates Grace's whole body.

"How are you?" Philip hugged Grace in his arms, took a knife from his body, and gritted his teeth at the wrist.

The pain of the blade's arrival could not keep up with the pain in Philip's heart, the beautiful Bloodgirl was already a part of his life, and Philip couldn't imagine waking up from sleep and not seeing Grace.

Bright red blood flowed from the straight wound, Philip was afraid that he would not flow quickly, squeezed it with his hand, and a large stream of red liquid poured onto Grace's lips, feeling the unique suction of the blood clan, Philip finally put his mind at ease.

The duchess's face finally had a hint of rosiness, and when she opened her eyes, she couldn't see her former figure, and a sense of powerlessness from the depths of her soul made Philip anxious.

"How's it going?" the man asked hurriedly.

"I, I feel like the blood vessels in my body are burning, and it hurts hotly. Grace's words made Philip anxious.

"I'm going to find Katrina. Philip picked up Grace and prepared to leave the lab.

In her arms, the duchess's weak voice came: "Yet, not yet, take me back to the Watson family, the blood pool can cure my ......" (to be continued......)
