There was a loud "boom", and the hammer bounced high in the huge force, and the steel plate on the ground twisted and deformed, sinking deeply.

Shi Madness roared, raised the hammer with both hands, and smashed it down again.

The ground was shaken, the dust above fell, and the steel plate that had been twisted and deformed immediately flew down with a "boom", and the entrance passage was completely smashed open.

Bai Ou protected himself with the knife in his hand and was the first to go down.

This underground is a huge research base, as Ma Yu said, although this research institution is named under the name of "Nan'an College", the actual background is complicated, and the guardian force here is extremely powerful.

An Ruoqing is only one of the people in charge, and the last incident had to be done at the same time by several bigwigs, so she reluctantly spared Bai Ou's death penalty, and even banished him to the "Nai He Valley", which can be said to be no different from sentencing him to death.

Wang Lie, the head of the Wang family, and the president and vice president of the "Nan'an Academy" have nothing to do with her, which shows how strong An Ruoqing is.

The entrance was smashed, which had already alarmed the security personnel inside.

There are two main types of people here, one who is mainly responsible for research, and the other is the security personnel who guard the safety of the place.

To be able to become a security guard here, the weakest must achieve mortal transformation.

A team of ten people, the captain of each team is served by a master of two changes.

In fact, as soon as the four Bai Ou people arrived here, they had already been discovered by the people who were secretly spying on them, but they didn't expect the Bai Ou four to come so quickly, and they even used violence to destroy the entrance, and rushed in directly, which caught them off guard.

By the time they began to spread the alarm and inform the security personnel to be vigilant, the four Bai Ou had already broken in.

When Bai Ou just appeared underground, these security personnel also reacted quickly, and a team of ten people rushed towards him.

The strength of the captain led by him has reached two changes, and the other nine team members have all changed from one to the other.

They were all dressed in light armor and held uniformly equipped military sticks as daily weapons, but in addition to military sticks, they were generally equipped with their own weapons, which were different, including swords, swords, axes, and spears.

In the long corridor, these ten people rushed over, and the captain led by him shouted: "Looking for death, you dare to trespass on the forbidden land-" He was the fastest, and the military stick in his hand slammed Bai Ou's head.

For intruders who dare to break into the door violently, there is naturally no need for mercy.

Bai Ou walked down, followed by Nie Tianhuan, Ma Yu and Shi Mad followed.

There was no need for Bai Ou to make a move, the three of them bypassed Bai Ou and took the initiative to meet him.

Nie Tianhuan's wrought iron rod was the longest, and he swept it violently, sweeping on the military stick that the captain had chopped over, and the powerful force directly shook the captain's military stick and flew out of his hand.

The captain exclaimed, the tiger's mouth immediately cracked, Nie Tianhuan let out a strange laugh, the iron rod was raised, and then it was pulled down heavily, directly hitting the captain's head.

The Heavenly Spirit Shell immediately shattered, and the captain's head shattered like a watermelon, and the blood mixed with the white brain pulp splattered together, and the head was blown out.

"Happy-" Nie Tianhuan laughed weirdly, blood splashed on his face, smelling the blood, he was excited.

Ma Yu and Shi Mad rushed up against the nine-person squad, like a flock of tigers and sheep, this is not called fighting, but slaughter.

Ma Yu's long sword was like a poisonous snake, specifically stabbing these people in the mouth, the long sword pierced into the mouth, crushed their tongues, and then emerged from the back of their necks, the technique was cruel and weird.

The slaughter of the stone madness was much simpler and more brutal, and he directly smashed the human body with this sledgehammer weighing dozens of catties.

Whether the opponent is in the head, chest or abdomen, as long as he is hit, he will immediately be crushed and killed.

A team of ten people was slaughtered by all three of them in the blink of an eye.

More squads appeared in the hallway, rushing towards them.

Nie Tianhuan and the three of them roared excitedly, rushing towards this group of people, like crazy tigers.

Bai Ou slowly followed behind them, keeping some distance from them, as if he was afraid of the blood splashing on him.

This group of people couldn't resist them at all, and they were quickly killed by the three of them all the way down the corridor.

Inside the corridor is the huge hall, which is filled with glassware and soaked in a large number of animals and humans.

The fighting here completely alarmed the entire underground research base, and teams of people appeared, including some panicked researchers fleeing inside.

Bai Ou followed Nie Tianhuan and the others into the hall, looked at the glassware around them, picked up a giant heavy axe from the ground, and smashed it at the nearest glassware.

There was a loud "boom", and the glassware immediately shattered, and a large amount of nutrient solution gushed out.

"Stop—" There was a shout in the distance, followed by five figures rushing towards them like lightning.

Bai Ou saw one of them, it was An Ruoqing.

These five people are the person in charge of this research machine, and An Ruoqing is also one of them.

These five people in charge are all masters of the "Transformation and Three Changes", and the five of them were furious, and they shot together, and immediately blocked Nie Tianhuan, Ma Yu and Shi Mad who were slaughtering everyone around them.

An Ruoqing also saw Shi Yu, and her face was full of astonishment.

She watched Bai Ou enter the "Nai He Valley" with her own eyes, how could she appear here now?

Stunned, she bypassed Nie Tianhuan and the three of them and ran straight towards Bai Ou.

"You...... How did you end up here? An Ruoqing was extremely surprised.

Bai Ou threw away the giant heavy axe in his hand and smiled a little weirdly: "I said it, we will meet soon." ”

"Look for death!" An Ruoqing was furious, and flew up with a kick, the shot was fast and ruthless, and the tip of the high shoe kicked directly into Bai Ou's face, this time she used real strength, this kick could completely kick Bai Ou's annoying face.

An Ruoqing's speed is very fast, she is not only the "Transformation of the Three Changes", but also the top master among them, and her strength is by no means below Nie Tianhuan.

It's just that she met the current Bai Ou.

Bai Ou didn't dodge, his counterattack was very simple, holding the knife in his right hand without moving, swinging his left fist, and punching the sole of the Gao Gen shoe that An Ruoqing kicked over.

With a "peng" sound, An Ruoqing suddenly screamed, her delicate body fell backwards in the air, and the tall shoes on her feet seemed to have been hit by an infinitely powerful hammer, and they immediately exploded.

She fell to the ground hard, blood was dripping from the sole of one foot, and the originally white and slender foot became twisted and deformed, swollen like a pig's trotter, and the blood vessels on it burst, and the foot bones were completely shattered.

An Ruoqing's face changed in pain, and her forehead was covered with cold sweat.

Her reaction was very fast, and she knew that something was wrong when Bai Ou's punch shattered the bones in the soles of her feet, and she fell and pushed her hands on the ground at the same time, and her body was pushed up, trying to get up again.

Bai Ouda strode forward and stepped down with a slam kick.
