The body of the gravel truck was covered with many hideous and sharp steel thorns, which looked full of a sense of intimidation, and this helicopter gunship had never seen such a thing, and it did not dare to approach rashly.

"Gravel truck, we were discovered by humans, what should we do?"

The transformed ambulance is called "Scalpel", and he asked as he looked at the helicopter that was shouting a warning.

"Yes, of course...... Kill! ”

The words of the gravel truck immediately provoked the response of these Decepticons, and they all turned into combat forms, and all the weapons on their bodies were aimed at this gunship, and there was a posture that would knock him down as long as it had any abnormal movements.

In the frightened eyes of the pilot, the black barrels of these iron bumps stretched out from their bodies, and he drove a helicopter gunship, and the speed was far from comparable to that of a fighter, so before he had time to turn around, an armor-piercing incendiary bomb ejected from the barrel easily turned the helicopter into a huge fireball, and none of the four crew members survived.

"Huh! Boom! Boom! It's been a long time since I've stepped on these insects! ”

A shell blasted the helicopter into a fireball, and the "Gray" let out a hoarse laugh, like two pieces of metal rubbing against each other, making people's teeth tingle.

Buzz!

At this moment, two gunships flew again from a distance, but this time the other side was clearly prepared, and a battalion of infantry and armor was drawn from the nearest military base to Detroit. A total of seven khaki XM1 tanks have already arrived here.

"Listen to the Decepticons inside, you have been surrounded, if you surrender immediately, we can give you political asylum qualifications......."

This time, it was an old member of the "Lair" unit commanded here, who had been fighting the Decepticons for two years, and was already a little familiar with the road at the moment, and he was shouting at the moment to distract the Decepticons while urging the transport plane carrying Optimus Prime to speed up.

"Optimus Prime is expected to arrive in 2 minutes, please help us buy time."

The two C17 transport planes have turned on their maximum horsepower and are flying towards Detroit, and the routes along the way are like school buses during the college entrance examination. All aircraft along the way that may intersect with the route of transport aircraft, whether private jets, civil aviation or fighter jets, must all obediently give way at this moment.

"2 minutes, okay, I'll try."

The team member looked at the huge figure in the binoculars, couldn't help but swallow, and then looked at the battalion commander next to him.

"Major Ferron, we'll have to wait two minutes."

"2 minutes? Although we have tanks, it is clear that such a little thing is difficult to pose a threat to the enemy, and long-range attacks are okay, and we must not let the other side get close, otherwise my tanks and soldiers will have to become Halloween potato cakes. ”

"Delay as much as you can."

The two of them glanced at each other, knowing each other that the so-called tank was useless in the face of a huge mechanical creature like the Decepticons.

"Gravel trucks, they seem to be dragging their feet."

The next minute passed, and the members of the lair force were shouting in unison, and the Decepticons were not acting rashly, but silently observing the number of human weapons, and after a few moments, the thorns that had turned into off-road vehicles suddenly spoke.

"It looks like yes, they should be waiting for Optimus Prime and them to arrive, which means that these people are not sure to leave us, okay, everyone is ready to work, Decepticons, attack!"

Cement was the first to rush out, but it was greeted by six missiles fired by three helicopters at the same time, exploding flames in the sky.

The flames dissipated, half of the cement shoulder was partially blown off, electric sparks flashed from the wound, and lubricants equivalent to human blood continued to flow out of the pipes.

"Damn, I was attacked!"

"Be careful!"

The scalpel gave a shout, and then a large PSG anti-materiel sniper rifle appeared on the left arm, aiming at one of the helicopters, and the result was no suspense, the helicopter exploded on the spot, and the fragments and aftermath of the explosion affected the nearby soldiers, and the other two helicopters hurriedly pulled up, for fear of being affected.

"Damn it, fire me!"

Major Ferron attacked, and seven XM1 tanks locked onto their targets at the same time, and the huge size of the Transformers, while having amazing destructive power, was also easy to be locked onto.

"Boom, boom, boom......"

The tank's shells accurately hit the Decepticons, blowing up a cloud of dust, and the cement pillar next to the abandoned factory had long been in disrepair, and the unstable gravel truck that was bombed by the tank hit the cement pillar with a butt, and the pillar in its twilight years suddenly could no longer support it and broke off with a bang.

All of this was like a multi-bony brand, which immediately triggered a chain reaction, these Decepticons were huge, they were unable to move in the factory, and accidentally touched other pillars, coupled with the deliberate command of Major Ferron, these tanks locked onto the pillars of the factory, and the walls opened fire, which soon caused the abandoned tall factory to collapse.

The area of the factory is very large, which can accommodate seven Decepticons that have changed back to their original shape, after the collapse at this moment, the heavy cement roof with amazing power, smashed on the top of the Decepticons' heads, Rao is robot can resist being smashed by some short circuits, and then these Decepticons were completely buried by the walls, roofs, and messy steel.

"It doesn't stop them from having much time." The members of the Lair Force looked at the factory and muttered, but a smile of victory appeared on their faces.

"But it's enough to drag them for 1 minute!"

On the southwest side of the battlefield, two large C17 transport planes had arrived, and then quickly landed in an open field, where several cars drove out and quickly turned back into Autobots.

Optimus Prime, the tallest, looked at the collapsed factory not far away. Thick rubble underneath. It's like some monster is crawling out. Then he nodded to Major Faeron, who was stunned next to him.

"Good job, humans, you can retreat to the back, we'll take over here. Ironsheets, cannons, get ready to work, Arsie, brakes, watch out for the enemy to escape. ”

"Yes, Chief."

The horizontal cannon and the iron sheet showed their weapons, and the two plasma cannons of the iron sheet began to condense blue and red light, and then aimed at the ruins.

"Although I have read the combat order. But it's still hard for me to believe that we have such a strong partner. ”

Major Faeron looked at Optimus Prime and then at the tank next to him, and suddenly felt a strong sense of inferiority, but he knew very well that this was not his battlefield, so he gave the order for the tank to retreat and support the front line in the rear.

Rumble!

An energy cannon flew out from under the rubble, blasting a large hole, followed by several more cannons, and the Decepticons, who were disgraced but not mortally harmed, struggled to crawl out of the rubble.
