Chapter 73 Martial God Thunder Sea

Chu Tiannan looked at the metal box in front of him with a strange expression.

I saw that the metal box was full of protective measures, with only a silver pen floating quietly on it.

"Recording pen?"

A secret book worth 20 billion, just a recording pen?

"Warrior, please show me proof of identity!" This is a security measure in the warrior system. Once someone maliciously obtains it, if the identity verification fails.

This priceless metal box will instantly turn into a time bomb!

"The protection measures are quite strict." Chu Tiannan shook his head and smiled, and then swiped his smart bracelet.

"Ding! Martial arts master Chu Tiannan, his identity is correct, the first three volumes of "Leilin War Technique", please sign for them!"

Following the system prompts, Chu Tiannan finally took out the silver pen and looked up and down.

"It's quite heavy. I didn't expect it to be made of mithril. It's so luxurious." The young man smacked his lips.

"Martial Master Chu Tiannan, this is a unique and precious item in my warrior shop. Only you are allowed to learn and practice it alone, and it is strictly forbidden to spread it to outsiders!"

"There will be three verification passwords in this recorder. There is only one chance to remember it, so you must remember it! Once you forget it, there is no remedy!"

"It is strictly prohibited to buy secrets and secrets for others, once you are found out."

"Death penalty! Immediate execution!"

Listening to the notes on the recorder, Chu Tiannan nodded slightly to express his understanding.

After all, it would be abnormal for something worth 20 billion to have no protective measures!

"You only need to enter the three passwords and the model number at once!" Chu Tiannan quickly memorized all the passwords of the recording pen.

"Martial Master Chu Tiannan, the recording pen has transmitted all the information and will self-destruct in ten seconds!"

"Nineteen. Two. One!"

boom!

In the tight basement, a muffled sound was heard along with a flash of light.

"Ahem!" Chu Tiannan said with a dark face, grabbing the smoking recording pen, and gritting his teeth: "Which bastard designed this, self-destruction with a shock bomb effect?"

The flash of light just now almost stunned him, but fortunately Chu Tiannan closed his eyes in time.

"Open the first volume of "Leilin War Techniques"!" Chu Tiannan impatiently controlled the intelligent projection and ordered.

At that time, many pictures appeared on the walls of the training room, among which a figure wearing silver appeared on the top of the snow-capped mountains.

The man in silver looked extremely ordinary, but Chu Tiannan's eyes widened.

Because he found that there was a faint silver lightning flashing around the other party's body, making a crackling and low sound.

"My name is Lei Hai!" The man in silver turned around slowly. His eyes seemed to be all-encompassing, making it difficult to see the truth clearly.

He seems to be an ordinary person, but in fact he contains unparalleled mysteries.

It's like a lightning abyss with no end in sight, and you'll fall right into it if you're not careful.

"This is the God of War," Chu Tiannan murmured in his mouth even though he was looking at the projection screen, but he could still feel the influence of the opponent's side of the world.

His eyes became even brighter and clearer. Isn't this what he has always wanted to strive for?

"The "Leilin War Technique" I created is to increase the speed to the extreme, as fast as lightning, as startling as thunder, and as powerful as thunder. In short, it can be said in one word."

"quick!"

"The practice of "Leilin War Technique" is extremely difficult and requires extremely high speed. The second is the control of the soul over the body. You must know that the soul is the foundation of human beings."

"All potential is the guidance of the soul, which bursts into the body."

Chu Tiannan nodded while listening. He didn't need to worry about his soul at all.

"As for the speed requirements, the warrior level must have the speed foundation of the martial arts master level, and so on," the man in silver continued in the video.

"If you find that your speed does not exceed your level when you practice the first volume, then you can give up."

"Because it's not for you!"

Hearing this, Chu Tiannan was secretly surprised. No wonder it was a unique strategy priced at 100 billion.

The speed requirement must be one level higher than the same level, which is obviously extremely difficult.

"The "Leilin War Technique" was something I came across accidentally in the stormy and thunderstorm zone of the Devil's Triangle." After a brief introduction by the man in silver, the next step was naturally an explanation of the secret skill.

Chu Tiannan felt hazy, half understanding.

Ding!

At this moment, Chu Tiannan's mind suddenly showed various battle scenes and practice demonstrations about "Leilin War Technique".

Like a lost person who suddenly finds the exit of a maze.

At the same time, the sound of swallowing the system emerged in Chu Tiannan's mind.

Host! The first volume of "Leilin War Technique" has been fully deduced.

The host has learned!
