Chapter 150: Test Mirror

Six months later.

In the artifact refining room.

Wang Yu was carefully assembling the components one by one. When he finally inserted an oval component into the back of a thick copper mirror, he let out a long breath.

This Mother-Child Floating Mirror, which integrated the artifact refining technique of the cultivation world and modern Blue Star technology, was finally completed.

At this moment, besides the copper mirror the size of a palm in his hand, there were two other copper mirrors on the table.

The three mirrors looked exactly the same in appearance, and their sizes were about the same. But only the mirror in Wang Yu's hand had a golden round bead embedded in the back, while the other two copper mirrors only had some hollowed-out patterns on the back.

The three mirrors were all oval-shaped, the backs were all crimson, and they were covered with various patterns of unknown use. The mirror surface was rough and silver-white. Not only could it not reflect the facial features clearly, but even the entire face could only be reflected vaguely.

He flicked his sleeve, and the two copper mirrors on the table were all collected. Then he walked toward the martial arts arena with big strides.

Since the artifact was refined, he naturally had to try its functions first.

In the martial arts arena, he took out the main mirror in his hand, and after fumbling around on his body, he took out three silver-white crystals, which were mid-grade thunder spirit stones.

These three thunder spirit stones were gathered only after he spent a lot of time and favors. Even if he wanted to prepare one more, he couldn't do it for a while.

Wang Yu pressed a thunder spirit stone onto the silver-white mirror surface of the copper mirror. The originally quiet copper mirror suddenly made a crisp mechanical sound. After a flash of silver light on the rough mirror surface, a hole actually appeared out of thin air, which "swallowed" the thunder spirit stone in one bite.

Then there was a roar inside the main mirror. The originally blurry mirror surface actually began to become smooth and snow-white, and at the same time, faint silver light flashed incessantly on the hollowed-out patterns on the back.

Seeing this, Wang Yu raised his eyebrows and slowly injected his internal mana into the mirror.

With two "swish" sounds, the other two copper mirrors flew out from his sleeves by themselves, circling his body and flying slowly.

And the moment these two sub-mirrors appeared, Wang Yu felt a pulling force from the copper mirror in his hand. After loosening his five fingers, the main mirror flew out automatically, joining the other two copper mirrors and circling him as well.

"A bit interesting. Is it an electromagnetic field?"

Wang Yu's expression moved slightly, muttering. After throwing the other two thunder spirit stones into the two sub-mirrors, he used his spiritual sense to guide the main mirror, formed a seal with one hand, and injected his internal mana along with his spiritual sense into the mirror.

"Puff!"

The main mirror shook and stopped in front of him. Red light flashed on the surface, eight crimson spirit patterns appeared, and a fist-sized fireball shot out from the mirror, hitting the empty ground several zhang away.

"Boom!" The fireball exploded, turning into rolling flames that swept out.

The next moment, the main mirror flew away. Another sub-mirror turned and stopped in front of him. The mirror surface flashed red light, spraying out a second fireball. Then this mirror also flew away, and the second sub-mirror stopped, spraying out a third fireball.

Seeing this, Wang Yu's eyes widened a bit, and he frantically injected his internal mana into the main mirror.

"Puff!" "Puff!"...

More than ten fireballs sprayed out from the three copper mirrors incessantly, turning the ground in front into a rolling sea of fire and rolling up a thick fire pillar that shot into the sky.

If it weren't for the fact that this martial arts arena, whether it was the walls or the ground, was built with a special stone material "Weak-Law Stone" that had extremely high resistance to spell power, it would have been shattered long ago and turned into rolling lava in the flames.

Wang Yu formed a seal with one hand, stopping the frantic outpouring of his internal mana. The red light on the surface of the three copper mirrors converged, and they stopped spraying fireballs.

But the next moment, he used his spiritual sense to communicate with another spirit-pattern pattern on the main mirror.

"Boom!" "Boom!" "Boom!"

The three copper mirrors emitted a roar simultaneously, and a layer of crimson light barrier appeared on the surface of the copper mirrors. At first, the diameter was only half a foot, but it immediately expanded frantically, becoming one meter in diameter, and twelve crimson spirit patterns appeared on the surface of each.

But immediately, the three light barriers dented inward on one side, and after a blur, they actually turned into three crimson light shields, which closely followed Wang Yu and circled around him, creating a series of shield phantoms, protecting him tightly in the center.

"This..."

Wang Yu was also startled by this change in the Fire Flame Barrier.

The manual only said that it could activate the Fire Flame Barrier on the mother-child mirror simultaneously, but it didn't say there was such a change.

However, the Fire Flame Barrier that had turned into a single-sided shield form seemed to be more solid than the original form in terms of defensive ability, and it should also be firmer.

However, he remembered that in the description, the Fire Flame Barrier seemed to have another attack-and-defense integrated defensive form.

Thinking of this, he formed a seal with one hand again, triggering a certain control spirit pattern in the main mirror.

The next moment, the three thick light shields that were circling him changed their form again, turning back into circular light barriers. Then, raging flames rolled up on their surfaces, turning into three giant fireballs with a diameter of one meter.

Under the rapid rotation of the three giant fireballs, the power of wind and fire merged, and the momentum of the fire flame increased several times, turning into layers of black-red fire curtains. Wherever they passed, flames rolled and fire clouds surged, and the momentum was like the appearance of a fire demon.

The martial arts arena, which was no more than one hundred square meters, was filled with rolling flames after Wang Yu walked a few steps subconsciously.

"Eh?"

Under this kind of power, why would he need to take the initiative to attack anything? As long as he got close and didn't let the opponent leave his side, the opponent would likely lose half their life first.

Seeing this, Wang Yu was overjoyed. He immediately formed a seal again, and the three copper mirrors blurred, stopping their rotation. The Fire Flame Barrier on the surface instantly dissipated, and the raging flames dissipated and vanished.

Below, he only had the attack spirit pattern of the Gold Needle Technique left to try. However, what was somewhat strange was that this attack spell was marked with a "use with caution" warning in the description of the design drawings given by Taiyuan.

This made Wang Yu feel a bit curious and expectant about this. After all, the eleven-inscription Fire Flame Barrier didn't have any special description, but this eleven-inscription Gold Needle Technique was specially explained by the system.

Then, his spiritual sense touched the golden round bead on the back of the main mirror.

"Sizzle!" "Clang!"

The three copper mirrors simultaneously emitted arcs of electricity, and then their surfaces began to twist and deform, various components protruding, and they actually turned into three mecha floating cannons that he was very familiar with.

Not bad, it was exactly the high
