When a series of dull explosions began to be heard on the ground, Sun Cheng was standing quietly in Laboratory 1 of the underground base.

"Are you going to start?"

The core functions are fully open, and more and more surveillance equipment has been disconnected from him, Sun Cheng is still unclear, but the surveillance equipment outside the base that he has let the sappers place has been found or destroyed.

Although there were constant explosions outside, he also knew that it was impossible for the Sound Nest troops to cause too much damage to the other party, at most they only hit the other party by surprise.

No, after coming to his senses, the sound nest soon began to use rocket artillery to violently clear the mine.

I believe that it will not be long before they will advance to the nuclear bomb silo.

Therefore, there is not much time left for Sun Cheng.

His brow furrowed suddenly, and he looked up at the reinforced wall above his head, and he quickly withdrew his gaze.

A radiation ball had disconnected the data and had obviously been destroyed, which made Sun Cheng's heart tense, and he knew that there was not much time left for him.

This is a war of his own, a war of only one man!

The Decepticon sappers don't have much combat power, and they may be able to rely on their physical superiority to fight the most elite soldiers of the human race, but they are not specialized combat units after all, and it is likely that only a few grenades or an anti-tank rocket can completely destroy them.

Although this exposure was beyond Sun Cheng's plan, he himself knew that even if he transferred the two only combat units under his command, the Precursor and the Madness, he would not be able to resist the Autobots who were heading straight for him.

The last operation in Tucson City gave him a lot of sense of crisis, and several high-level Autobot fighters were dispatched together, Sun Cheng was not Megatron, and it was not impossible for a link to be left behind.

Therefore, this time he must deal a heavy blow to the Sound Nest troops, so that the US government behind the Sound Nest understands that he is not easy to mess with.

His eyes turned to his face again, a huge box, and Sun Cheng finally made a move in his hand.

This is an ordinary cargo ship container, made of general standard throughout, and does not seem to have any peculiarities.

However, Sun Cheng slowly stretched out his palm towards it, and after the palm was attached to the container, a message immediately sent out from the core along his palm.

In the next second, the container seemed to disintegrate, and the boxes in the four directions of the front, back, left and right at the same time emitted an indiscernible sound of mechanical rebound, and then they all parted, revealing two huge humanoid bodies that were quietly placed in the container.

Self-built industrial robots No. 19 and No. 20!

These are the two new industrial robots that have been built at Site 2 in Brazil!

However, the slight difference is that No. 19 and No. 20 are not ordinary industrial robots!

His gaze lingered on the two robots for a moment, and Sun Cheng had anticipation in his eyes.

The industrial robot was a project that he had started temporarily because of the serious shortage of Decepticon sappers under his command.

Based on the existing industrial robot templates on the earth, it is made by using some technology from the planet Cybertron and copying the database of the sappers, because it does not have much intelligence in nature, and strictly speaking, it is just a more advanced industrial machine than the existing industrial robots on the earth.

At first, Sun Cheng had no intention of militarizing it, after all, he himself had a Decepticon body, and naturally knew very well that the mechanical beings from the planet Cybertron were like gods in front of machines, especially those equipped with electronic components.

He was worried that he had managed to build an army of robots, but when he fought with the Autobots or other Decepticons, he was easily controlled by others, and all his efforts were wasted.

However, the impact from the moon that day made Sun Cheng suddenly realize that although the industrial robot he made was clumsy, it didn't seem to be as easy to be affected as he imagined.

It is based on this discovery that he is ready to restart the previous armed robot program, and the two industrial robots numbered 19 and 20 are the test products that Sun Cheng himself used to practice.

As soon as the core moved, two liquid metal bone joints immediately stretched out from inside and outside his body, instantly connecting to an inconspicuous socket on the two unopened No. 19 and No. 20 in front of him, and then the two pieces of information data were quickly injected into the internal processing center of the two robots.

"Squeak......

With the sound of metal joints, the bodies of 19 and 20 suddenly began to tremble violently.

Not long after, as their eyes suddenly opened, the cold hollow electronic voice immediately sounded, "Combat Robot No. 1 and No. 2 have been activated, and the core functions have been activated...... Activate the automatic adjustment function...... Load battle data...... Detection of weapons and ammunition stockpiles...... Determine the task [Eliminate all intruders]...... Unknown packets are found and cracked begins...... The data cracking was completed, and it was determined that the unknown data was [Internal Structure Diagram of Base 1]...... No. 1, No. 2, sortie ......"

Boom!

After the completion of the start-up, the two modified industrial robots No. 19 and No. 20, which had not yet completed debugging and finalization, suddenly jumped up and jumped up with unimaginable flexibility, and the heavy weight immediately left two dull echoes in the empty laboratory at the moment of landing.

Feeling that the data scanning eyes fell on his body, Sun Cheng did not interfere with interest.

He's loaded the Identification Friend or Foe System in the Core Processing Center of 19 and 20!

It didn't disappoint him, this system easily helped 19 and 20 determine their identities, and after the scanning, the two bodies were no less than Sun Cheng, and the modified robot, which was far two circles larger than ordinary industrial robots, immediately walked towards the outside of the laboratory without looking back according to the task he left!

"The next step is to test their combat effectiveness!"

The gaze only retracted as the 19th and 20th completely disappeared, and Sun Cheng continued to lock on to the two of them uninterruptedly while controlling the core in order to collect combat data.

On the other side, after receiving the latest transmitted data from outside the base, the corners of his mouth arced larger and wider, and the faint blue light in the eyes of a pair of electronic eyes was already cold to the bone!

"So, it's almost time to clear the field!"

With an indifferent sentence to himself, Sun Cheng suddenly raised his head, and several control data were immediately sent out from the core.

The next moment, the other five automatic land-based missile launch systems that were lying in ambush outside the base were activated, and after immediately locking onto the targets hovering in the sky, they simultaneously launched the self-loaded improved Hellfire missiles in unison.

In the meantime, two hidden places outside the base!

Two long boxes buried in the shallow underground floor, suddenly after receiving two remote boot data, the LCD screen on the surface of the box suddenly began to light up with a red countdown watch.

“10，9，8…… 3，2，1！ ”[.]
