Mu Jingfan never thought that he would return here again one day, the exterior here was no different from what he had seen in the past, and even the traces after the last battle with the chief of staff had been perfectly erased. It's just that it's hard to imagine that this research institute, which is likely to have been abandoned, has become a stronghold for the 'ghosts'.

"I should have figured out that since the chief of staff is here, Tianqi must be able to grasp some of the secrets of ZF. After that incident, most of the classified documents in this place should have been removed, and the place became a no-man's land. ”

What's more, it is absolutely impossible to find this place if the Duhuashi family and ZF well water do not interfere with the river water.

Taking a deep breath, in this place, Mu Jingfan knew that he had to raise his spirit, and if he was not careful, he would become food for the 'Yin Spirits'.

As for why Hua Ziyan chose to tell him this news, he still can't figure it out.

Entering the research base from the familiar entrance, the appearance inside ZF didn't have the leisure to clean, and the original white and clean passage still retained the trouble that Mu Jingfan had broken through when he came over last time.

The abandoned laboratory still retains the traces of the last battle with Tie Zhengyang, and it seems that the 'Yin Spirits' are also quite lazy guys, and these places have not been cleaned at all.

Passing through the first layer smoothly, Mu Jingfan didn't feel any 'ghost' breath, but now he has no other clues, so he can only go down.

After reaching the second basement floor, the atmosphere here has obviously changed. The aura in Mu Jingfan's body was about to move, and the smell of 'Yin Soul' suddenly became much stronger.

"It's so close to their range of activities?" The entire research base has a total of eight floors, and Mu Jingfan can't believe it, just here there is such a strong smell.

In a trance, it seemed that the roaring voices of the 'ghosts' could be heard.

Coming to the third basement floor, the power supply on this level seems to be cut off, and the corridor is black, except for some fluorescent-coated signs that glow dimly on the walls, which looks extremely terrifying.

Stepping into the darkness, Mu Jingfan immediately felt a chill from his back, as if he had stepped into the Netherworld, but as soon as he thought that Tieyun Tower had been brought to such a dangerous place, he immediately cheered up and continued to move forward.

'Hot Hitomi'

The aura quietly merged into his eyes, and Mu Jingfan tried his best to control himself from making a sound, so as not to alarm the 'Yin Spirit'.

On the fourth floor of the basement, the power returned to normal again, and he could breathe a sigh of relief when he walked out of the darkness, but before it was Mu Jingfan's turn to relax, the crisis sense immediately reminded him to dodge.

Just now, at the place where he landed, a swallow-tailed nail slowly turned into black smoke and dispersed.

"Who is it?"

All that answered him was deathly silence.

Mu Jingfan didn't know when this 'Yin Spirit' approached him, he didn't feel anything unusual at all just now, but soon, that feeling of danger also reappeared.

Several poisonous needles flew towards Mu Jingfan from all directions, and if it weren't for Mu Jingfan's 'hot pupils' that hadn't dispersed, there might not have been any way to notice these tiny iron needles.

'The Power of Burning Gold'

The situation changed in an instant, and Mu Jingfan flashed away at an extremely fast speed. He knew that he couldn't continue to be stunned, and now that the other party had discovered him, there was no need for him to act slowly and carefully.

'Inch'

The figure rushed through the corridor quickly, and all the hidden weapons behind him couldn't keep up with his speed. It's just that this crisis is not as simple as a hidden weapon.

The wall of the corridor in front of him suddenly expanded, and the invisible heat filled the entire area, and with the flash of a ray of fire, the gases that leaked out of the wall were instantly ignited, and the flames directly enveloped Mu Jingfan.

It's a pity that Mu Jingfan's fire attribute aura is born with a strong ability to resist external flames.

"In this way, those hidden weapons just now are also traps in this corridor, and they will take the initiative to attack me, which means that someone has already noticed me, right? Mu Jingfan thought while paying attention to his surroundings.

On the other side, in the dim monitoring room, there was a person who was observing Mu Jingfan's every move from all angles. It can be said that Mu Jingfan has already entered the sight of others from the moment he stepped into the first layer.

Coming to the fifth basement floor, the hallway was filled with the smell of blood, and it was hard to imagine what was going on here. But Mu Jingfan could feel that he was getting closer and closer to the enemy.

As soon as they reached the middle of the hallway, the other party reacted. The high-voltage power grid extending from the wall squeezed towards Mu Jingfan, looking like he was going to roast Mu Jingfan.

'Flame Hunting Blade'

It's just that Mu Jingfan's two fire blades flew out, directly melting a big hole in the power grid in front of him, which was able to allow himself to pass through.

"I don't know who you are, but you should also know that these little tricks are useless to me, can we skip this pre-trial part?" shouted Mu Jingfan after escaping from the trap.

He knew that the other party must be observing him through the camera in this corridor that he didn't know where to hide, so it was a bad feeling to be alone in the dark all the time.

"Then you can come to the seventh floor to find me, if you can come down. A familiar voice sounded on the radio, but Mu Jingfan couldn't remember where he had heard it.

The elevator door to the lower floor was opened, and the sixth, seventh, and eighth floors could only be accessed by elevator for special reasons, and Mu Jingfan could only accept the other party's challenge.

The elevator did not take Mu Jingfan directly to the seventh floor, but stopped at the sixth floor underground, but this was also expected by Mu Jingfan. There is a high probability that at this level, Mu Jingfan will encounter real danger.

The moment the elevator door opened, a pair of sharp claws swept towards the door, and the air waves directly left claw marks inside the elevator, but fortunately, Mu Jingfan was prepared and hid on the zenith one step in advance.

'Flame Hunting Blade'

Kicking out two fire blades, Mu Jingfan rushed out of the elevator under the cover of the fire blade, not knowing how many people there were outside, if he was blocked in the elevator by the other party, it would be very dangerous.

Land, turn, parry the opponent's claws. There was only one 'Yin Soul' in Mu Jingfan's eyes, but this 'Yin Soul' gave people an unusual feeling.

The body shape can only be regarded as ordinary among the 'ghosts' that Mu Jingfan has seen, but the muscle lines on his body are very perfect, if this is a human being, it must be the 'Mr. Bodybuilder' who can win for ten years.

His eyes were full of energy, and beneath his ghostly face was a gray cloth robe, which had been shattered by the ravages of time, but what was left had been fused with his power, painted with black lines that represented his strength.

The 'Yin Spirit' in front of him, like Hua Ziyan, gave him a considerable sense of oppression.

"Is it another 'Yin Soul' at the Commander level?" Mu Jingfan didn't dare to be careless, when he reached the Boss level 'Yin Soul', he would awaken some special abilities, and after reaching the Commander level, because his sanity became complete, they would only be more comfortable using their own power, and they would be several grades stronger than before.

As for how much stronger, Mu Jingfan has already experienced it in Hua Ziyan.

"Since you want to be my enemy, you should know my name, the third commander of the Tiger Army, Zhao Guanhai, remember, this is the name of the person who ended you. ”

"Don't you ask my name?"

"There is no need, the dead are not worthy to be remembered. Zhao Guanhai put on a posture, obviously going to attack.

The other party is so confident, and he also has the capital of self-confidence, even the power of Fang Cai's horizontal claw should not be underestimated.

'Inch'

Mu Jingfan has always been the first to attack, and his body is advancing extremely fast, and he has already come to Zhao Guanhai in the blink of an eye.

"Too slow. Before the punch came out, Zhao Guanhai hit Mu Jingfan's abdomen with a blow to the top of his knee, and under the huge impact, Mu Jingfan's back hit the zenith and fell down heavily.

Zhao Guanhai didn't take advantage of this opportunity to attack, what he was eager for was not a simple victory, but to crack all the moves that the opponent had shown with all his might.

'Flame Blade Flurry'

Mu Jingfan, who fell to the ground, did not stop attacking, his body rotated, and he quickly kicked out multiple flame blades while getting up. When the fire came, Zhao Guanhai's expression did not change at all, but his hideous face could not see any change.

I saw that his steps were staggered, and his body twisted at an incredible angle, and these flame blades did not even touch his shadow.

"It's just a façade. ”

"What about this move?" Mu Jingfan attacked again, the acupuncture hole gushed, the speed was only better than just now, and the crimson fist struck out, and even the air seemed to be ignited.

This blow made Zhao Guanhai's eyes light up, seeing that Mu Jingfan had consciously guarded against his next game, Zhao Guanhai simply did not use the next section to counter the other party, but turned his hands into palms and greeted Mu Jingfan directly.

"Your every move is too wide open, and when you crush your opponent in all aspects, you will appear to attack quickly and the enemy will be defeated one after another. But someone can see your flaws, and all your attacks will become your weaknesses. Suddenly, before Mu Jingfan could react, his palms were already attached to his arms.

Zhao Guanhai took three steps back, his hands were wrong, Mu Jingfan could only feel an irresistible force coming from his arm, and in order not to hurt his right arm, he could only let his body twist with this force.

After spinning in the air many times, Mu Jingfan was kicked away by Zhao Guanhai, and his body hit the wall again.
