Gao Wu: The opening system made me the devil

"Brother-in-law, be careful!"

Nangong Yan's face changed slightly.

The three mutated mice rushing towards Luo Tian were all warrior-level, her heart rose, she blamed herself secretly, she knew that Luo Tian was waiting in the car.

However, she was not slow on her feet, and she was about to go to the rescue as soon as she turned around.

"Do not bother me!"

However, at this moment, Luo Tian's voice suddenly sounded.

In the next second, under Nangong Yan's surprised gaze, Luo Tian stomped on his feet and charged towards the three mutated mice.

Luo Tian was so fast that he even left a series of afterimages behind him.

"Agility!"

Nangong Yanmei's eyes flashed, and she was slightly startled.

"Although the rank is not high, it is at least a small success stage."

"Squeak!"

However, before she could think about it, a group of mutated mice rushed forward, opened their mouths, and rushed towards her with a stench.

Immediately, the mind was absorbed, and the icy breath filled the air. Nangong Yan swung the sword, and the cold blue immediately formed a sword curtain.

The two mutated mice were beheaded in an instant, and the cuts of the head and body were covered with a sheet of frost, so that no blood could flow out.

On Luo Tian's side, he stepped on the Moon Shadow Step, and his figure instantly bullied the three mutant mice.

There was a glint in his eyes, and Luo Tian turned the long sword in his hand slightly, at the same time, a vigorous sword intent erupted, and a sharp breath radiated out.

"Wind Killing Sword!"

With a sigh in my heart, the long sword rolled out like a gust of wind.

Chi Chi Chi!
In an instant, the sound of a sharp knife piercing into flesh came, and three blood holes appeared on the body of the fastest mutated mouse.

"Squeak!"

The ear-piercing screams spread, and it crashed to the ground.

A flash of sword light followed closely behind, piercing through its head in an instant.

"it is good!"

Seeing this scene out of the corner of her eye, Nangong Yan couldn't help admiring inwardly, and at the same time felt even more horrified.

If she read it correctly, it should be Sword Intent, right?That is an artistic conception that only the Grandmaster Realm can touch. Why did Luo Tian just comprehend it when he was in the Warrior Realm?
At this time, the mutated mouse of the martial artist level had already rushed to her, and she had to temporarily suppress the many doubts in her heart, and the sword scene reappeared.

【Ding!Kill a mutant mouse and get a human-level upgrade card. 】

"Ok?"

At this time, Luo Tian heard a system notification sound in his mind, and he was overjoyed. He never expected such a harvest.

Immediately, Luo Tian looked excitedly at the other two mutant mice.

Stepping on the Moon Shadow Step under his feet, his figure moved like a ghost, and instantly avoided the attack of the two mutated mice.

Then, the intent to kill again arose, and the sword light swept past like a gust of wind.

The two mutated mice that had just landed on the ground suddenly burst into several bloody mouths, and blood flowed horizontally.

"Squeak!"

The two mutated mice screamed at the same time, turning their heads to look at Luo Tian in horror.

However, what greeted them was a bright cold light.

The screams stopped abruptly, and a blood hole appeared on the heads of the two mutated mice at the same time.

【Ding!Kill a mutant mouse and get a basic level upgrade card. 】

"Here it comes again! Two mutated mice, one of which directly exploded the upgrade card. Although it is the basic level, the explosion rate has increased significantly."

"Could it be...beheading has a higher explosive rate than defeating it?"

Luo Tian became interested instantly, as if he had finally discovered the true usage of the system.

In the next second, his eyes glowed brightly, and he raised his eyes to look at Nangong Yan.

At this time, Nangong Yan was dodging around, avoiding the intensive attacks. The long sword in her hand was chilling, and she slashed out from time to time. Each sword could take away the life of a mutant mouse.

She was alone, completely suppressing a group of mutant mice, without any pressure at all.

Luo Tian suddenly felt a little heartbroken, those might all be upgrade cards one by one.

"Yan'er, I'll help you!"

Without further delay, with one step, Luo Tian rushed towards Nangong Yan like a gust of wind.

"Brother-in-law, be careful!"

Nangongyan was slightly startled, changed her previous offensive, and suddenly bullied the mutated mouse the size of a calf, forcing it back instantly.

At the same time, she swept out with a sword, several mutated mice were cut out of the battle circle by her, leaving only two mutated mice in place.

When Luo Tian arrived, the sword intent swept across, and the Wind Killing Sword moved to the extreme, rushing out at a tricky angle, leaving a series of afterimages in the air.

In an instant, the heads of two mutated mice were beheaded.

【Ding!Kill a mutant mouse and get a basic level upgrade card. 】

【Ding!Kill a mutant mouse and get a human-level upgrade card. 】

"Hahaha...the beast is nothing more than that!"

Luo Tian was very excited. If there are a lot of upgrade cards, why bother to practice hard every day.

As a hanger, one should have the consciousness of hanger, what are you doing so hard to practice?Wouldn't it be nice to just upgrade it with one click?
Luo Tian was full of pride: "Yan'er, leave the big one to you, and leave the rest to me!"

"Brother-in-law, don't be careless!"

Nangong Yan frowned, worried that Luo Tian would be too conceited.

However, Luo Tian didn't pay much attention to it, he exhaled and said, "Don't worry, it can be covered!"

"System, use all two human-level upgrade cards to upgrade Moon Shadow Walk!"

【Ding!Consuming two human-level upgrade cards, the level of Moon Shadow Walking will increase, and the current level is 11. 】

In an instant, Luo Tian's body skills improved a level, from the peak of the small to the great, and it was about to reach the peak.

Luo Tian had already estimated before that the upper limit of human-level martial arts is fifteen, so every three levels is a comprehension stage.

For others, it is completely impossible to improve a martial skill to a great level without a period of hard training.

But he is different. He has a system, which saves most of the time virtually. As long as there are enough upgrade cards, he can completely level up a martial skill in an instant, or even break through the upper limit.

This is the joy of hanging batches!

At the moment when the stature upgrade was completed, Luo Tian's speed suddenly increased sharply, and he flickered around, his figure was completely unpredictable.

At the same time, the Wind Killing Sword was used, and under the blessing of the sword intent and a full 360 cards of blood, it cut the air and spread towards the mutant mice.

"Great skill!"

Nangong Yan was startled, but immediately became happy.

The stronger Luo Tian was, the better he was.

Dacheng's human-level agility is enough to deal with the current predicament.

Of course, to be on the safe side, she still didn't leave all the mutated mice to Luo Tian, ​​but blocked four mutated mice by herself, including that giant calf-like rat.

The battle has officially entered a white-hot stage.

Luo Tianjian was like a gust of wind, blood would fly wherever it passed, and the lives of mutant mice were taken away by him.

【Ding……】

【Ding……】

【Ding……】

Continuous prompts sounded in my mind, forming a beautiful symphony.

Five minutes later, Luo Tian killed five mutated mice again, and obtained three human-level upgrade cards and two basic-level upgrade cards.

On the other side, in front of Nangong Yan, there was only that mutated giant rat that looked like a calf.
