How fast does lightning travel?

Some people say that it is close to the speed of light, while others say that under certain circumstances it exceeds the speed of light and can approach infinity...

After Hong Kang finished dissipating the evil energy of the black iron, a strange phenomenon suddenly appeared in the sky and there was an endless rumbling sound.

His heart was beating wildly in an instant.

In an instant, the black iron was thrown out.

"Crack~!"

There was a thunder on the ground, and the explosion was sharp and unusual.

A dazzling white lightning fell from the sky, winding like a snake, lighting up the surrounding areas, and struck black iron in the sky.

The air wave caused by the impact suddenly spread out, and a large group of sparks even fell on the ground.

The dissipated electric light spread along the air to Hong Kang's body, and a numbing tingling sensation suddenly arose.

"What a critical moment!......"

Empress Hongkang was extremely frightened.

The temperature brought by lightning can reach tens of thousands of degrees Celsius, which is several times the surface temperature of the sun. Hong Kang cannot guarantee that his current body can withstand it.

"Eh~?!"

Hong Kang's eyes were suddenly attracted by the black iron in mid-air.

This piece of black iron was not damaged by the white thunder bombardment, and Hong Kang felt that there was a vague connection between himself and it, and he felt a sense of closeness.

As if...as if I could control it~!

Hong Kang tried to think, and saw the piece of black iron suddenly twisting like a ball of water.

"It's really okay~!"

Surprised in his heart, Hong Kang immediately sketched in his mind the shape of the wooden knife he had used in the Ming Dynasty.

It won't take a moment.

The black iron changes like water, gradually forming the shape of a knife.

As soon as Hong Kang thought, the black knife flew into his palm with a "swish".

When I started, there was no residual high temperature from being struck by lightning. Instead, it was close to Hong Kang's body temperature.

Hong Kang looked at it carefully and saw that this black knife was about four feet long. The body of the knife was narrow and thick, and the back of the knife curved with the blade.

The blade is dull and matte, and the whole body is pitch black.

It is a kind of pure black that seems to be able to swallow everything~!

At first glance, it seems unremarkable, but after a closer look, I feel that although the entire black knife does not have any gorgeous patterns, it always has a noble and simple taste.

"Good knife! Good knife~!"

"Hahaha………!"

Hong Kang smiled happily, and followed the feeling of closeness, gently stroking the black knife blade.

At the junction of the handle and the blade, there is a branch-like lightning strike texture, which vaguely forms two ancient characters that resemble phoenix seals and dragon seals - Netherworld.

"Netherworld?!"

Hong Kang frowned.

"This name doesn't suit my taste, and it has a ghostly feeling. It would be better to call it 'Xuan Ming'."

As soon as the words fell.

Suddenly, a few lines in the branch-like lightning strike texture twisted and bent.

After it stopped, the two ancient characters suddenly turned into "Xuan Ming".

"...Forged by Heavenly Thunder, spirituality is self-generated!~"

"Okay, okay, hahaha..."

Danced with a sword.

With a flick of the finger, a clanging sound was heard.

Hong Kang worked from bottom to top, concentrated his mind, and slashed toward the sky!

In this slash, Hong Kang used 70% of his strength, and the blade of nearly 200 meters roared into the sky.

"Today, let's try to kill the sky~!"

The broken cumulus clouds were estimated to be four to five hundred meters high from the ground, and the sword could not reach them.

However, the Dao Gang cut by Hong Kang seems to have spirituality, and can gather the energy of heaven and earth to strengthen itself during the process of rising to the sky.

The sharp breath cut through the atmosphere and still flew far away.

Suddenly, several cumulus clouds that were floating in the sky suddenly split open, and a thin blue ribbon abruptly divided the cumulus cloud group into two.

This scene seemed like the sky had been split open!

………………

Such an abnormality immediately attracted the attention of people within a kilometer range of "Blackwater Academy".

Someone screamed: "Look, the sky is cracking~!"

"What? Let me see, let me go~! It's really...!"

"Let me tell you, who are you two acting for?!" Some people were disdainful, but their expressions instantly distorted and their voices became shriller, "I am! ~Fengqian~~!"

Someone pointed to the distance and said, "It's in the direction of the Academy."

The man immediately sat down calmly and took a sip of water: "That's okay! By the way, who is going to invite us to this meal today?~"

Everyone outside could notice it, and Zhang Sanfeng and Pang Qingyang could sense the overbearing force of the sword.

While being frightened, everyone used their skills to move towards Hong Kang.

………………

Hong Kang raised his head and looked at the sky.

His eyes are bright and shining.

Hong Kang's eyesight is getting better and better now. Sitting upright on the ground, he can even see clearly the water droplets and mist in the clouds.

He saw that the dense mist water droplets accumulated in the clouds were affected by wind pressure and were trying to move closer to the center.

But the thin blue band in the center still has the remnants of its own Dao Gang. As soon as it gets closer, it is cut into smaller white clouds. However, the presence of wind pressure makes the broken cumulus clouds look like moths flying into the flame.

It went back and forth repeatedly, and after a long time, until the sword completely disappeared, it gradually continued to drift in the wind.

"Brother, is this black knife...?"

Pang Qingyang's eyes were fixed on the four-foot black sword in Hong Kang's palm. Her sword heart told her that this black sword, which looked ordinary, was actually extremely dangerous!

"This is made of that piece of black iron, named [Xuan Ming]. Look at the texture here, it was just struck by lightning!"

Zhang Sanfeng took the black knife and felt it carefully.

Said: "The awe-inspiring feeling of the evil light is gone. Although it is still as dark as ink, the aura is very pure..."

Pang Qingyang continued: "More than that, I can sense that this black sword is also born with spirituality. Brother, you used [Forging Technique]? But you can't use that spell?~"

Hong Kang said: "That's not the case."

Then, he briefly talked about what happened just now.

Pang Qingyang's wonderful eyes widened slightly: "Made by nature!..."

Zhang Sanfeng stroked his beard and smiled and said: "Xuanzhe is the name of profoundness; Mingzhe is the name of tranquility."

"Xuan Ming is the source of wonder, so it is called Wu instead of Wu."

"It starts from Xuan Ming and turns to Datong; it starts from Xuan Ming who has heard of it, and there are only a few ginsengs heard in Xuan Ming."

"Fellow Taoist, this name shows the meaning of seeking the Tao~!"

………………

Yujian Villa.

Yin Tianqi, dressed in a powerful outfit, tossed and turned and punched like a shadow.

If you look carefully, the surface of his fist seems to be dotted with strands of ice marks, which is very cold, but it can be seen that it is not a decoration.

"Drink~!"

Yin Tianqi's face flashed with green energy, and his skills were concentrated on the front of his fist.

The cold fist blasted into the pond in an instant.

He yelled in his heart:

"Tian Shuang Fist!
