Gao Wu: The opening system made me the devil

"Squeak!"

The giant mutant rat was isolated and helpless, its small dark eyes were full of hatred, its limbs bent, and the giant mutant rat rushed towards Nangong Yan at a terrifying speed.

Nangong Yan's face remained unchanged, and the cold blade pierced out of the air.

when!
There was the sound of clashing gold and iron, and the giant mutated rat was sent flying upside down, and a layer of frost even formed on its sharp claws, hindering its movement.

"Squeak!"

There was an angry neighing sound, and the mutated giant rat suddenly turned around and rushed towards the drain pipe.

"Go away!"

Nangongyan stomped her footsteps, her figure was like lightning, she instantly bullied her, her long sword fell, and instantly cut a bloody mouth on the back of the mutated giant rat, but because of the ice attribute, the giant rat's blood did not flow out.

However, a terrifying chill still swept through its whole body, and its movement speed suddenly slowed down.

Nangong Yan didn't talk nonsense, the three swords fell at the same time, the mutated giant rat screamed, the blood all over his body was frozen, and he couldn't run anymore, the creaking sound became low and finally dissipated.

At this point, all the mutated mice in the sewage treatment plant were killed, and Nangong Yan walked towards Luo Tian holding a long sword.

Luo Tian's thoughts were concentrated in his mind.

"System, increase the level of the Wind Killing Sword."

【Ding!Consumes three human-level upgrade cards, and the level of the Wind Killing Sword is increased. The current level is 15, which has reached the upper limit. Do you want to break through the upper limit? 】

"breakthrough!"

Luo Tian didn't hesitate at all, and the guess in his heart was also verified. No matter what the level of human-level exercises, the upper limit is 15.

【Ding!In the breakthrough of the upper limit of Fengshajian, please choose the strengthening direction, 1. Strengthening the sword speed. 2. The scope is strengthened. 】

"Huh? It's not a characteristic, but the strength of the sword itself."

Luo Tian murmured, two reinforcement directions, very easy to understand.

A sword speed and a slashing range are both useful.

After thinking about it, Luo Tian chose one.

【Ding!The upper limit has been successfully broken through, and the level of the Wind Killing Sword has been increased, currently level 16. 】

A lot of insights flooded into his mind, roughly the same as the previous Fengshajian, but Luo Tian could clearly feel that the current Fengshajian is faster and more difficult to defend against.

"Unfortunately, the basic level upgrade card is useless now."

Luo Tian secretly sighed, his eyes fell on the basic level upgrade card, suddenly, a reminder sound came from his mind.

【Ding!Two basic-level upgrade cards can be fused into one human-level upgrade card. Is it fused? 】

"As expected of you, the system!"

"Fusion, fusion!"

Luo Tian never expected that the system would bring such surprises.

【Ding!The fusion is successful, and the human-level upgrade card x2 is obtained.]

"Use the upgrade card to improve the warrior-level physical skills!"

Luo Tian gave the order directly.

Moon Shadow Walking is still 4 levels away from breaking through the upper limit. It is meaningless to improve at this stage, but the improvement of warrior level physical skills can increase the level of characteristics, which is currently the most cost-effective.

【Ding!Consumes two human-level upgrade cards, and the warrior-level physical skill level is increased, currently at level 10. 】

【Ding!The Unlimited Stamina trait has been increased, currently 5%. 】

Luo Tian's physical fitness has been enhanced, and his unlimited physical fitness has also been improved. This wave is perfect.

It's a pity that the sword intent has not been enhanced, it is still 10%, and the blood has not been increased for the time being. After all, this cannot be directly improved, it needs to be tempered, and can only be condensed by self-cultivation.

But this is not a problem. With the improvement of basic physical skills and physical fitness, it is almost not difficult to increase Qi and blood, but it only takes some time.

"Brother-in-law!"

Finally, Nangong Yan also came up to her, staring at Luo Tian with her beautiful eyes.

"what happened?"

Luo Tian smiled, already having a guess in his heart.

"Why is your level of martial arts so high? I remember that you have never been exposed to martial arts before, and you have only been in school for two days. If there is no accident, it should be taught by the instructor just now?"

Nangong Yan asked out the doubts in her heart.

"Besides, you actually comprehended the sword intent. What happened to you?"

"really!"

Luo Tian knew that Nangong Yan wanted to ask these questions, and to be honest, he really didn't know how to answer them.

Saying that you have a system, is it a hanging batch?

Leaving aside whether Nangong Yan believes it or not, once this matter is exposed, it may lead to death. It's not that Luo Tian doesn't trust Nangong Yan, but that this matter is too unbelievable.

After thinking about it, Luo Tian could only perfunctorily say: "If I say that I am a peerless genius, I can master martial arts as soon as I learn it, and understand my artistic conception as soon as I realize it, would you believe me?"

"letter!"

Unexpectedly by Luo Tian, ​​Nangong Yan nodded solemnly.

Before Luo Tian was surprised, Nangong Yan said, "Besides this, I'm afraid there is no better explanation. I heard that in the black blood race, there are strong people who can reincarnate their souls, but brother-in-law shouldn't be? After all, we are very We've known each other since we were young."

"Uh, of course not, but does reincarnation really exist?"

Luo Tian himself is a time traveler, time travel is very strange, but he never thought that there is someone besides him who can do such a thing.

"There should be nothing wrong, after all, this is what my dad told me."

Nangong Yan nodded.

"Ok!"

Luo Tian nodded slightly.

As one of the top ten saints, Nangong Ao will definitely not joke casually. He said that there is, so there is a high probability that this kind of existence really exists.

"Okay brother-in-law, let's not talk about this, these are too far away from us, the task is completed, we can go back."

Nangong Yan wanted to leave after speaking.

"it is good!"

Luo Tian stepped forward to keep up.

"Help...help me!"

However, at this moment, a voice came.

The two paused at the same time, looking at a broken pipe.

I saw a woman drilled out of the pipe breach, her body was covered with stinky residue, and her eyes were terrified.

"It's the person who was captured by the mutant giant rat, let's go there!"

Nangong Yan spoke hastily, turned around and walked towards the woman.

Luo Tian followed quickly, and the two of them soon arrived in front of the woman.

The woman exuded a pungent stench, but it was nothing to the two of them.

"You, are you warriors? Those, those things?"

After the two approached, the woman asked tremblingly while looking around.

"We are warriors, those are mutated mice, we have already killed them, you are fine."

Nangong Yan spoke softly, stretched out her hand, and motioned for the woman to grab her.

Now the woman is in a half-kneeling state, and her body is still shaking.

"Thank you, thank you!"

The woman also saw the corpse of the mutated giant rat not far away, most of the fear in her eyes dissipated, and she slowly raised her hand.

But at this moment, a dazzling sword light suddenly appeared and attacked the woman.

"Brother-in-law!"

Nangong Yan was shocked!
