After being promoted to the fourth order, Xiao Nan's speed was even faster, and at noon the next day, Xiao Nan came to the outside of the underground laboratory of the Yin Demon Alliance.

Looking at the little meow on his shoulder, Xiao Nan said softly: "This time, no one can stop us!"

"Meow!" Xiao Meow naturally knew that Xiao Nan had been promoted to the fourth order, and echoed in a loud voice.

He is familiar with the earth-based ability, but this time, he can't get in anyway. It turned out that Shangguan Zhuo had learned the lesson of the last time, and he actually covered the walls around the laboratory with a layer of steel plates, hindering the use of earth-based abilities.

There was no way, Xiao Nan had no choice but to kill from the front.

But before that, for the sake of safety, Xiao Nan still put on a mask.

"Who is it?" Xiao Nan had just advanced more than a hundred meters when he was spotted by a bunch of patrolling guards.

Seeing them, Xiao Nan did not hesitate to draw the water sword, cast the speed ability, and killed them.

"Click!" The sound of guns sounded, and when the guards saw Xiao Nan draw their swords, they also immediately opened fire.

It's a pity that after being promoted to the fourth rank, Xiao Nan no longer takes this ordinary gun in his eyes. In the frightened eyes of the guards, Xiao Nan was like a phantom, getting closer and closer to them.

"Poof!" the sword slashed off the head of one of the guards.

Then, the sound of "poof!" and "poof!" rang out continuously.

The five guards were quickly solved by Xiao Nan one by one.

Five warm currents swept by, Xiao Nan looked at the corpses on the ground, and five fireballs swung out, igniting their corpses.

On the water sword, it is still bright as new and extremely sharp. Xiao Nan couldn't help but praise it, and inserted the water sword back into the scabbard.

After killing two more patrolling guards, Xiao Nan finally came to the small warehouse.

Press the elevator and watch the elevator slowly descend towards the second floor. Xiao Nan pulled out the water sword and prepared for battle.

"Ding!" the elevator door opened.

Xiao Nan stepped out of the elevator in one step, and without waiting for the guards outside the elevator to react, he swung his long sword and killed the two guards on the spot.

"Ah......h

"Enemy attack!" Some people reacted quickly, instantly understood Xiao Nan's identity, and shouted a warning.

At this time, everything was in Xiao Nan's planning, and Xiao Nan sneered directly, and unhurriedly swung out several huge fireballs in a row, smashing towards those instruments and equipment in the hall.

Not only that, Xiao Nan was also holding a sword away from the water, constantly attacking the people in front of him. Whether it was the experimenters in white coats or the guards with guns, Xiao Nan showed no mercy and killed them one by one. Little Meow was not idle, and also kept waving her claws at the guards holding guns.

Soon, the whole hall was ablaze, and many experimenters even risked their own safety to rescue the instruments and materials.

Xiao Nan's face turned cold, and several wind blades flew out.

"Look for death!" At this moment, Shangguan Zhuo's voice sounded. At the same time as the voice, there was also Shangguan Zhuo's attack.

"Bang!" a water arrow stabbed towards Xiao Nan with great force.

Xiao Nan stood on the spot, looking at the water arrow with disdain, welcoming its arrival.

Finally, the water arrow stabbed Xiao Nan, but to Shangguan Zhuo's surprise, Xiao Nan was unharmed.

"You also have a water ability?" Shangguan Zhuo was shocked. At the same time, his heart sank, so that he would not have the slightest chance of winning.

"If you only have this ability, today is your death date!" Xiao Nan said calmly.

"Do you know who you're fighting against?" Shangguan Zhuo began.

The last time I bypassed you, this time, you don't have that luck. Xiao Nan said lightly.

"It was you last time?" Shangguan Zhuo was even more shocked. Last time, the other party was obviously only a third-order ability, and as soon as he appeared, he scared the other party into fleeing immediately. How long has it been? The other party has actually been promoted to a fourth-order ability, and has come to take revenge.

"There should be no one in the most taboo base city to be promoted to the fourth order, who are you?" Shangguan Zhuo asked in a deep voice. He couldn't figure out Xiao Nan's identity.

"Tell you what else it means, take it!" Xiao Nan used his newly obtained Nine Tricks Qiankun Sword Technique to stab at him.

"Bell!" the two swords intersected. Shangguan Zhuo's weapon was also a long sword, but at this moment, in the first encounter, his long sword was actually cut off by a blow from the water sword.

"How is it possible?" Shangguan Zhuo looked at the short sword in his hand with a face full of disbelief, and roared: "This is a second-order long sword of mine, how can it be broken?"

Xiao Nan was excited in his heart, and he was very pleased with the sharpness of the Lishui Sword, a good weapon is like this, it can improve people's combat effectiveness too much.

At this moment, Xiao Nan killed Shangguan Zhuo too easily. His abilities are completely restrained by himself, and his weapon is a short sword, and the end can be imagined.

A few minutes later, Xiao Nan stabbed Shangguan Zhuo's chest with a sword, ending the life of the deputy leader of the Yin Demon Alliance.

Subsequently, Xiao Nan burned all the instruments and equipment in the laboratory, and those information documents were also left, not a word was left, and then he left here with Xiao Meow in the frightened eyes of others.

"Now, it's time to go to the headquarters of the Yin Slash Alliance, Qinyue Villa!" Xiao Nan said coldly.

This time when he came back, except for Huang Yingying, his biggest purpose was to completely destroy the Yin and Evil Alliance. Root out this evil force that is inflicting on the low-level supernatural of Base City.

Xiao Nan destroyed all the instruments and equipment, so it was impossible for anyone to report here. And at Xiao Nan's current speed, I believe that no one will run in front of Xiao Nan.

Therefore, Xiao Nan was not in a hurry, even so, Xiao Nan still returned to the base city on the afternoon of the third day.

After resting at home until the evening, Xiao Nan walked out onto the street and walked in the direction of Qinyue Villa.

"Little Meow, you have to contribute later, there are no good people in the headquarters of this Yin Demon Alliance. Xiao Nan whispered to Xiao Meow.

"Meow!" Meow whispered, agreeing. Actually, Xiao Meow is still reluctant to kill, Xiao Nan has long found out that Xiao Meow would rather lie there all day long, a veritable "lazy cat".

It was still the wall last time, and Xiao Nan easily climbed over it.

After killing two groups of guards along the way, Xiao Nan once again came to the two-story building by the lake.

Last time, Xiao Nan killed Liu Yongqi who was cheating with Lu Wanhou's lover here, this time, I don't know if Lu Wanhou will live here.

Standing outside the small building, Xiao Nan clearly heard the sound of a woman laughing from inside. It seems that Lu Wanhou is most likely here.

Thinking of this, Xiao Nan pushed the door and walked in.

As a result, the scene in front of him made him dumbfounded.

Lu Wanhou is indeed there, and the woman is also there, but in addition to them, there is also a middle-aged man.

"Uh......" Xiao Nan was a little speechless, and said embarrassedly: "You guys are too good at playing." ”
