The ray lasted for eight seconds before stopping, and the barrel returned to black. Even if it was more than ten meters away, the heat emitted from the muzzle could be felt.

"Electro-rays!"

The dwarves were silent until Kestagin made a sound and suddenly realized his face.

He had already recognized the spell released by the electric cannon.

It's electric light rays.

The high-frequency fire just now was also emitted by electric and light rays, but the speed was too fast. The electric and light rays at the lowest three rings were compressed and released more than a dozen times in one second, achieving a powerful effect like artillery bombing.

The second continuous strafing was the original form of the electric light ray, but only the power was similar to the Seventh Ring Spell.

However, the range of the electric light cannon is more than ten times!

Kestagin couldn't understand how Rennes did it?

He can also use electric and light rays. If controlled in the three rings, he can also emit instantly, but he must not emit more than a dozen times in one second, and he cannot even reach three times. This is far beyond the speed limit of ordinary people's thinking, and the range is even more incredible.

Where does the energy of the electric cannon come from? What is its operating principle?

Kestagin had countless questions in his mind.

However, this is not the end.

The electric cannon was silent for half a minute, as if waiting for the barrel to cool down, and suddenly started to operate again.

A ball of blue light appeared at the muzzle, but it was not emitted, quickly condensed into a larger group of light, and countless energy was poured into it. The group of light became larger and larger, and the electric light became more and more dazzling, like a small sun that was invisible to look directly.

The dwarves held their breath and stared at them intently.

Finally, after twelve seconds, a rumbling sound broke out like a bolt from the blue, causing the dwarves to subconsciously cover their ears and unable to help track the landing point of the light.

Half a second later, a violent beam of light burst out in the field of vision.

Everyone closed their eyes.

A shocking explosion immediately came, followed by a strong shock wave. The city walls under construction trembled, but fortunately they were far apart and did not cause damage.

When the explosion subsided, the dwarves saw a large open space appearing in the forest three thousand meters away.

Things within a hundred meters of the explosion point were destroyed.

There is a deep pit in the middle of the open space. The forest a hundred meters away falls down radioactively, as if it is bombed by a meteorite.

"this……"

All the dwarves who saw this scene were frightened, their lips trembled, and they stopped their work.

"This is all the power of the Nine Rings spell!"

Kestagin could hardly believe his eyes.

No wonder Rennes said it was different from rune cannons, which were not so terrible at all.

Such a terrifying blow, which was obviously a certain change mode of electric light rays, reached the power of the Nine Ring Spell!

He turned his head suddenly to look at Renn, his eyes full of fanaticism.

"Ren, the most powerful cannon in the world of electric light cannon! No, it is the most powerful weapon in the world!" Kestagin's voice trembled a little, and he whispered loudly in an almost admiring tone: "If you can teach me the methods and principles of electric light cannons, I am willing to be loyal to you in the name of God and become your follower for life!"

Not only Kstakin, but also many dwarves were also moved and hurriedly chose to come over.
