Riding to the heavily guarded place found before, then, Tu Hao quietly sneaked in, but, unfortunately, Tu Hao was discovered by a very secret camera before he could advance, and immediately, a piercing alarm sounded.

Seeing this, Tu Hao couldn't help but sigh lightly, "It would be nice if there was a mechanic's disguise." However, since it has been discovered, Tu Hao can only break in.

Thinking of this, Tu Hao took out the M-137 Green machine gun, a big killer, from the base, and then, a long chain of bullets was also pulled out of the base by Tu Hao and wrapped around himself.

Then, Tu Hao strode forward, and soon Tu Hao came to a rock wall, and on the rock wall there was a large gate, and at this moment, there were many guards gathered near this gate, apparently, these guards had gathered after hearing the alarm.

"It's okay, solve it at once, and I'll find it one by one." Looking at the overwhelming guards, Tu Hao did not panic at all, but pressed the motor button of the M-137 Grimm machine gun, and the next moment, the barrel of the Grimm machine gun began to rotate rapidly.

"Shoot, shoot!!"

Seeing the Grimm machine gun in Tuhao's hand spinning rapidly, the guards guarding outside the gate shouted, "Why.

However, how could the pistols and rifles of those guards be the opponent of Tuhao's Grimm machine gun, when the fierce tongue of fire gushed out from the Grimm machine gun, those guards could not organize a decent counterattack at all, and were completely crushed to death by Tuhao's Grimm machine gun. For a time, the guards suffered heavy casualties.

A minute later, one of the bullet chains Tu Hao took out was finished, and at the same time, the barrel of the Grimm machine gun also entered a cooldown of 3 seconds, and this time was just enough for Tu Hao to change bullets.

"Die!!"

Just as Tu Hao was changing the chain, a rocket suddenly came from a distance, but it was a surviving guard who got a bazooka from nowhere.

Looking at the oncoming rockets, Tu Hao, who had changed the bullet chain, raised the Green machine gun in his hand violently, and then, pressing the firing button, suddenly, the tongue of fire broke out again.

"Boom!"

Before the rocket could get close to Tuhao, it was exploded by a volley of bullets, and then, the guard with the bazooka was also torn apart in the dense bullets.

When the second minute passed, there were no more living people at the gate, even if it was an F-level martial artist, he couldn't get close to Tu Hao who was holding a Grimm machine gun, because the F-level martial artist was far from being able to reach the level of immunity to bullets, especially this kind of Grimm machine gun with a rate of fire of 600 rounds per minute, not to mention an F-level martial artist, even a FF-level martial artist had to avoid its edge in the face of the Grimm machine gun.

Holding the Grimm machine gun, Tu Hao walked into the gate with blood, all the way forward, under the powerful fire of the Grimm machine gun, no one could stop Tu Hao's footsteps at all.

Soon, after violently blasting open a door with a Grimm machine gun, Tu Hao came to the real yàn room mentioned in the data, and the moment he entered the real yàn room, Tu Hao was also shocked by the scene in front of him.

During the test, there were huge glass jars filled with this green liquid, and each glass jar was soaked with strange looking 'humans', if these humans with snake heads or human lion heads were still human.

Tu Hao knew that these people were originally just ordinary people, and they were caught here by the people in the casino, injected with the genes of mutant beasts, and finally became like this.

"Whew~~"

Taking a deep breath, Tu Hao raised the Green machine gun again, and then aimed the muzzle at the glass jars, and the next moment, tongues of fire shot out, and the glass jars in the real room exploded one after another, and the test samples inside were also torn apart by the dense bullets. These people are not human, beasts and monsters should not exist in this world.

After destroying all the glass jars he could see, Tu Hao continued to walk towards the interior of the real yàn room, and after a while, Tu Hao came to the depths of the real yàn room, which was full of all kinds of human stumps and severed arms, and it was obvious that this should be the core area of the real yàn room.

"Little brother, don't be impulsive, I'm also forced." Seeing Tu Hao appear, a man with glasses in a white coat put down a mass of human internal organs in his hands, raised his hands, and said.

"Yes."

Hearing this, the corners of Tu Hao's mouth cracked slightly, and the next moment, the tongue of fire of the Green machine gun tore the man in the white coat to pieces, "At first, you may have been forced, but now you are not ......" Tu Hao looked at the man in the white coat who was not blind, and said.

After killing the man in the white coat, there was no one alive in the entire real room, at this moment, Tu Hao felt a little unaware of himself, originally he was just a harmless game house for humans and animals, but now he can do 'kill without blinking'. However, Tu Hao did not regret this and did not have any burden in his heart, because the people he killed were all deserving people.

Since there are no more living people in the entire real room, Tu Hao also put away the Green machine gun, and then, Tu Hao couldn't help but turn his gaze to the large metal iron door in front of him, from the thickness of this metal door, Tu Hao felt that this could not be cracked by violence, but the things inside made Tu Hao very curious.

Such a well-defended place must have an amazing secret inside, and at the same time, in the information that Tu Hao saw before, it was also very vaguely mentioned many times that the things behind the big iron gate were mentioned, but the information did not reveal anything about the specific changes behind the big iron gate, which shows that the secrecy behind the big iron gate is extremely high.

"Zero, can you crack it?" Tu Hao looked at a cipher disk next to the big iron gate and said.

"Yes, but it will trigger the alarm." Zero was silent for a moment, then said.

"No problem." Hearing this, Tu Hao nodded, now this real room is Tu Hao alone, even if the alarm is triggered, no one will come.

With Tu Hao's authorization, a beam of light shot from the Zero Tong Guò Tactical Watch connected to the system in the real room and began to crack the defenses of the large iron gate.

In the process of cracking, sure enough, as Zero said, the alarm in the real yàn room sounded loudly, and then, a burst of machine qì started sounded, and when he heard the sound, Tu Hao's heart tightened, and he thought that there would be some strange defensive measures in this real yàn room, however, after waiting for a while, he didn't see any movement, and Tu Hao suddenly put his mind at ease.

After a while, Zero completed the system cracking, and suddenly, the closed metal door slowly opened, and immediately, Tu Hao walked in quickly.

After entering the gate, Tu Hao was greeted by a glass jar filled with turquoise liquid, but this glass jar was several times larger than the outside, and at the same time, the periphery of the glass jar was covered with various instruments.
