Super Invincible Devouring System

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, and there was only a silver pen floating quietly on it.

"Recording pen?"

A cheat book worth 200 billion is just a recording pen?

"Warrior, please show your identity certificate!" This is a security measure in the martial artist system. Once someone maliciously obtains it, if the identity verification fails.

This priceless metal box will instantly become a time bomb!
"The protection measures are quite strict." Chu Tiannan shook his head and smiled, and then flicked his smart bracelet.

"Ding! Martial master Chu Tiannan, your identity is correct, please sign for the first three volumes of the three "Lei Lin's Art of War"!"

Following the system's prompt, Chu Tiannan finally took out the silver pen and looked it up and down.

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

"Warrior Master Chu Tiannan, this is a peerless and precious item in my martial artist store. You are only allowed to learn and practice alone, and it is strictly forbidden to spread it!"

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

"It is strictly forbidden to buy secret books and secret methods for others, once it is verified and caught."

"Death penalty! Execute immediately!"

Listening to the precautions of the recorder, Chu Tiannan nodded slightly to express his understanding.

After all, something worth 200 billion is not normal without protection measures!

"Three passwords. You can input the model at one time!" Chu Tiannan quickly memorized all the passwords of the recorder.

"Warrior Chu Tiannan, the recorder has sent all the information, and it will self-destruct in ten seconds!"

"Nineteen. Two. One!"

boom!
In the tight basement, there was a muffled sound accompanied by a flash of light.

"Ahem!" Chu Tiannan had a dark face, grabbed the smoking recording pen, gritted his teeth, and said, "Which bastard designed this to self-destruct 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 "Lei Lin's Tactics of War"!" Chu Tiannan commanded impatiently while controlling the smart projection.

At that time, many pictures appeared on the walls of the training room, among them a figure in silver clothes appeared on the top of the snow mountain.

The silver-clothed man looked very ordinary, but Chu Tiannan's eyes widened.

Because he found that there were faint silver lightning flashing around the opponent's body, making a low crackling sound.

"My name is Lei Hai!" The silver-clothed man turned around slowly, his eyes seemed to contain everything, making it hard to see the reality.

A seemingly ordinary person actually contains unparalleled mysteries.

It's like a lightning abyss with no end in sight, if you are not careful, you will fall directly into it.

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

His eyes became brighter and clearer. Isn't this the goal he has always wanted to work hard for?
"The "Leilin Warfare" I created belongs to the category of raising the speed to the extreme, as fast as lightning, as startled as thunder, and as powerful as thunder. In short, it is just one word"

"quick!"

"The cultivation of "Lei Lin Warfare" is extremely difficult, and it 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 a person."

"All potentials are guided by the soul, and then burst into the body"

Chu Tiannan nodded while listening, he didn't need to worry about the soul at all.

"As for the speed requirement, that is to say, the martial artist level must have the speed foundation of the martial artist level, and so on," the silver-clothed man continued in the video.

"If you find that your speed has not exceeded your own 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 the price of 1000 billion peerless tactics.

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

""Lei Lin Warfare" is something I comprehended by chance in the stormy and thunderstorm area of ​​the Devil's Triangle, it" the silver-clothed man gave a brief introduction, and the next thing was naturally an explanation of the unique skills.

But Chu Tiannan felt vaguely, half-understood.

Ding!
At this moment, Chu Tiannan's mind suddenly displayed various battle scenes about "Lei Lin's Art of War".

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

At the same time, the voice of devouring the system emerged in Chu Tiannan's mind.

Host! The first volume of "Lei Lin's Tactics of War" has been fully deduced.

The host has learned!
