Xiao Yu approached the metal giant, and pressed it in a hidden position under its armpit, and the metal giant let out a soft 'buzz' sound, as if a car was on fire, and its huge body trembled slightly regularly.

At the same time, a small door large enough to accommodate one person to enter and exit opened from the metal giant's chest, and Xiao Yu clicked on his toes, jumped up, and his body was light, like Ru Yan Toulin, and went straight into the small door.

There is not much space inside the small door, it looks like a cockpit, surrounded by a 360-degree holographic screen, and a wide seat is placed in the middle, Xiao Yu sits on the seat and puts a helmet-like thing on his head.

An electronic sound suddenly rang in Xiao Yu's ears.

Start Authentication ......

“…… Authentication passed! This is your first time driving the Thunder, is it initialized? ”

"Yes!"

"Initialization Setup Successful!"

"Check the energy and weaponry!"

"60% of the energy remains, which can support a continuous combat time of ten hours, weapons and equipment: an electromagnetic pulse energy axe, a plasma shield, a high-vibration particle knife, and twenty infrared-guided high-explosive bombs!"

This is the first time that Xiao Yu has connected with the mecha's intelligent light brain after escaping from the underground base, and this feeling is both strange and familiar.

The control of these mecha is not complicated, and the intelligent light brain of the mecha is connected with the human brain through the smart helmet, and the control is carried out with mental power, which can achieve the effect of making a finger.

It's just that this kind of control method is extremely depleting of mental power, the more advanced the mecha is more demanding on the user's mental power, if the user's mental power does not meet the needs of this mecha and reluctantly controls the mecha, it will cause the brain blood vessels to burst and die of hemorrhage because of the high load on the brain.

Sometimes, the entire skull will burst open due to excessive brain pressure, and it will become a headless corpse.

At the beginning, in the underground base, all Xiao Yu could drive was the three primary mechas, 'Yumi', 'Qingming', and 'Sky', and for him, the 'Thunder' advanced melee mecha was an unattainable existence, and only the best students in the heart group could fly it.

But I didn't expect that after two years, I would be able to sit in the cockpit of the 'Thunder', and with my current level of mental strength, driving the 'Thunder' was easy, and I didn't feel any pressure at all.

Xiao Yu felt that at this moment, he had become one with this metal giant, as long as his mind moved, the metal giant would make corresponding movements without the slightest delay.

Controlling the 'Thunder' to sit up from the ground, all the surrounding scenery was captured by the holographic scanning device on the 'Thunder's body, and fed back on the 360-degree holographic screen in the cab, without missing anything.

"Note that there are humanoids approaching ahead, twenty-six in number, 100% hostile, 0% threatening."

As soon as the electronic sound fell, a group of heavily armed black-clothed guards appeared at the gate, and when they saw the metal giant in the room with a single horn and a half-sitting height of three meters, they couldn't help but gasp in unison, and they all paused, and the few people who ran in front even sat on the ground in fright.

The appearance of this metal giant was too powerful, especially the two electronic eyes flashing red, which made people shudder when they saw it.

", this ...... What the fuck is this! A black-clad guard forcibly suppressed the fear in his heart, and a foul word burst out of his mouth.

Just as they were about to send someone forward to test it, the metal giant suddenly stood up from the ground, its movements were so flexible that it didn't make the slightest sound of metal rubbing, and it was obvious that the lubrication of the joints was quite good.

Fortunately, in order to place some large experimental instruments in this underground base, the distance between the floor and the ceiling on each floor is very high, more than ten meters, and the huge body of the metal giant can actually stand upright without touching the ceiling.

Seeing that the metal giant was actually moving, a captain-like guard had a discolored face, picked up the light submachine gun in his hand, pointed at the metal giant in front of him and shouted to his subordinates, "Fire!" ”

"Dada......"

More than twenty submachine guns erupted long tongues of fire, and the bullets rained down on the metal giant like a storm.

However, this level of attack, for the 'thunder', is almost equivalent to tickling, there is no need to make any protection at all, the bullet hits its body, the 'dangdang' sound repeatedly, all of it is bounced, where can it be injured?

Xiao Yu was in no mood to deal with these little people at this time, his heart was full of hatred, he couldn't vent his anger, and he was secretly ruthless in his heart, "Okay!" Since you're going to restart the Predator Project, I'll demolish your underground base first! ”

'Thunder' took a step, like a giant tank, and slammed into the wall next to it!

'Boom! 'There was a loud bang, and the dust flew around!'

By the time the black-clad guards were able to see what they saw, the metal giant was gone, leaving a huge humanoid hole in the wall!

Several screams came from the next room, followed by a series of loud 'bangs'!

And then there was another dull 'thud'!

The black-clothed guards were shocked, and hurriedly ran to the humanoid hole, and looked into the next room, only to see several staff members squatting in the corner shivering, and a large experimental instrument placed in the middle of the room had turned into a pile of scrap metal.

On the opposite wall, there is another huge humanoid hole!

For a moment, there was a constant thump, apparently the sound of the metal giant crashing against the walls of the room.

"It'...... What does it want to do? Do you want to tear down the entire underground base? The black-clothed captain of the guard had a shocked look on his face, and he was speechless.

Ten minutes later, all the rooms on the entire fifth floor were swept by the 'Thunder', and all the experimental equipment was destroyed everywhere it passed, and no one could stop the 'Thunder'.

Just when everyone thought that the metal giant had to stop, they saw it pull out a huge long-handled battle axe wrapped with terrifying electric light from its back, and slammed it into the ground.

'Boom! The lightning rolled, as if the entire floor trembled under the power of this axe, seven or eight meters thick, and a large hole with a diameter of five or six meters appeared in the reinforced concrete floor.

Looking at this big hole, almost everyone covered their mouths and looked at all this in disbelief, what kind of weapon is this? How can it be so powerful?

In front of everyone's eyes, the metal giant jumped towards the mouth of the cave, and jumped into the big hole in a daze.

Immediately afterward, there was another dull 'thump' sound on the next floor.
