'Click! After a brief pause, he threw the grenade out of the roof fence with his wrist. At the same time, he himself was a fish leaping behind a huge chassis a few meters away.

With the strength of the wrist and the control of the body that was promised at this time, the powerful MK3A2 drew a graceful parabola in mid-air, crossed the roof fence and flew into the air with extraordinary accuracy.

Originally, if there had been no accident, the grenade would have exploded before it hit the ground, but the accident did happen.

A U.S. Black Hawk helicopter slashed diagonally from another building on the opposite corner. Machine guns were set up in the hatches that opened on the sides of the fuselage, and several US officers and soldiers were fully armed and ready to land on the roof.

At this time, the Black Hawk helicopter was flying towards the roof of the building where the promise was located, but it had no idea that a grenade would be accurately returned into the door of the plane they had opened.

Not only was the grenade very accurate, but it was also well timed. Not only is it just right, it's just stuck in time.

The grenade is a single throwing weapon, because it is held in your own hand at the beginning of use, so in order to ensure the safety of your own people, it has a time-delay detonation setting. Some special grenades can be long or short, but they are usually within seconds.

The helicopter is a very fast flying machine, and its hatch is really difficult to accurately grasp in flight. After all, it's fast, and it's hard to hit even if you aim with a gun, let alone get a grenade into it accurately. The difficulty is similar to that in the drama.

What was supposed to be almost impossible happened.

Xu Promise found the best route accurately with unparalleled sharp judgment. And in a very short time, he used his strong nervous reflexes to coordinate his body, and threw an MK3A2 with the safety pin pulled into the cabin with the side open. And the timing is extremely precise.

"Boom!" There was a deafening roar in the air, and even the Transformers in the fierce battle couldn't help but glance at it.

The power of the military grenade was unimaginable, and a huge explosion in the engine room destroyed the internal structure of the Black Hawk, and several US officers and soldiers, including the chief and co-pilot, were all killed or severely injured in the explosion. The helicopter that lost control roared through the air and crashed to the ground in black smoke and flames.

The helicopter slammed to the ground with a loud roar, and the propeller, which was still spinning at high speed, swept through the ground and stirred up a large cloud of gravel and dust. Whoever was accidentally hit by the rain all fell into blood mold.

This kind of force is almost fatal enough to hit the body. Fortunately, the propeller that rotated at high speed was not thrown out, otherwise the people who were affected would be the real tragedy.

"Give me the source of the fire!" After using the red spider to temporarily entangle Optimus Prime, Megatron flew up to the roof of the building and transformed, and then pounced on the promise.

His red eyes were filled with nothing but the source of fire. This is the core of the Transformers, and it is also the greatest guarantee for the realization of Megatron's personal pursuit.

As long as he has the Tinder Source, Megatron will be able to use the power of the Tinder Source to gradually rule the entire universe. It's a power that only a god can have.

Promise was already standing on the top of the fence on the roof of the building, glancing at the street below him, and watching Megatron, who was like a raging beast, raised his hand and threw a grenade, "Bye-bye." ”

Promise jumped backwards and jumped straight down the street!

This is the sixth-floor roof of a department store, not an ordinary residential building. Jumping from such a high height is a great danger even if it is promised. However, while the Promiser was still in mid-air, a huge mechanical palm suddenly reached over and firmly held him in the palm of his hand.

Optimus Prime is here.

Red Spider couldn't resist Optimus Prime, and even a little time he bought wasn't enough for Megatron to take the promise. And when Promise saw Optimus Prime flying towards him, he took the initiative to jump down, because he knew that Optimus Prime would definitely catch him. After all, Optimus Prime's height is there.

"No !!" Megatron, who rushed to the roof of the building with endless pieces of gravel and dust, roared and tried to chase after him, but several American helicopters in the sky came nearby and fired heavily at Megatron, who was actively exposed in mid-air.

"There's no time!" Back on the ground, Optimus Prime knocked away the vertigo with three punches and two kicks, and then turned his gaze to Promise, with a touch of irrepressible anxiety in his voice: "Put the source of fire in my chest!" In any case, the source of fire cannot be allowed to fall into the hands of the Decepticons and humans! ”

The current situation is definitely very bad for the Autobots. The Decepticons' side is already evenly matched, and the human army that is constantly throwing into the battlefield has become a huge threat to them at the moment.

Optimus Prime has the character of a virgin, but that doesn't mean he's a fool. In fact, to be able to convince the Autobots, Optimus Prime's wisdom is even higher than that of Megatron!

The source of fire cannot fall into the hands of the Decepticons, as all Autobots know. The Decepticons use the source of fire to turn all machines on Earth into killing tools. But Optimus Prime also said that it is worth looking for if it cannot fall into the hands of humans.

In fact, the Transformers with advanced technology have already invaded the human Internet, and the so-called firewall of mankind is almost useless in front of them. In this case, Optimus Prime has long had a general understanding of the human world.

He then promised to inform him of humanity's research on Megatron and his ambition for the source of the fire, which opened a door in Optimus Prime's heart.

Wait until you've seen what humans do in the base beneath Hoover Dam. Optimus Prime has already decided that humanity also wants to crack the secrets of the source of the fire, not for peace, but for conquest and ambition. This is no different from the Decepticons.

Once the ambitious humans crack the secret of the Tinder Source, it is as if they had imprisoned Megatron for decades, and he treated him like an experimental guinea pig. Definitely not good news for the cosmic world.

Although they are enemies of each other, in fact, Optimus Prime and Megatron are not only best friends when they are far away on Cybertron, but they are also in power! Watching Megatron be imprisoned and studied for decades, it's hard to imagine that Optimus Prime doesn't have any compassion in his heart.

Now the situation is clear, with the increasing number of human armies, it may not be long before none of these Transformers want to leave here. However, the source of the fire must never fall into the hands of the Decepticons and the human army. Forced into desperation, Optimus Prime had no choice but to sacrifice himself to destroy the source of the fire.

As long as the source of fire is destroyed, no matter how things develop in the future, it will not cause much damage. At most, it is just the sacrifice of all the Autobots. As an Optimus Prime with a noble character, he really didn't take it to heart when sacrificing anything.

"Don't!" As soon as Optimus Prime's words fell, the autobots beside him immediately panicked.

As mentioned earlier, the only way to destroy the source of fire is to plug in the source of fire. into the chest of the leader to destroy. And the destruction of the source of fire also means the death of the leader. Among the current Transformers, the only ones who can be called leaders are Optimus Prime and Megatron.

Needless to say, Optimus Prime was thinking about snatching the source of the fire, how could he destroy himself? Moreover, if he wanted to defeat Megatron and forcibly stuff the Tinder Source into his chest, he simply couldn't do it at this moment with the human army constantly surrounding.

In the distance, many large transport planes had already appeared, which were US reinforcements that had received orders to take off urgently. In order to reclaim their own treasures and add more at the same time, the Americans have begun to launch an all-out campaign.

With the U.S. military's strong transport capabilities, they would be able to drop a large number of troops into nearby areas in a matter of hours at most. Although the Transformers will not be locked by radar satellites and so on because of advanced technology, after the physical blockade of the ground and the sky is completed, the Transformers will no longer have the possibility of escaping from the encirclement.

In order to completely eliminate the Peep and possible danger of the Decepticons and humans on the source of the fire, it is also to be able to make it possible for his companions to escape. Optimus Prime ultimately chooses to sacrifice himself.

Although Optimus Prime's determination can be called great and selfless. But the promise is impossible to promise, because this is the goal of his mission!

Before the ring gives a clear affirmation, the promise will never let go of the fire source.

"It's useless for you to ask for this." Wise as Optimus Prime quickly sensed the idea of making a promise, and wondered, "The source of fire is actually only available to us Transformers. With your human technology, without our help, there will be no hope of using the Tinder Source for at least a hundred years. ”

"That's why District 7 will do everything possible to capture you alive." Promise's eyes flashed, and he watched as the cars around him temporarily blocked the external attack, and began to delay with Optimus Prime, "Otherwise, do you think we can continue to stand here and talk now?" The missiles of the US military have already fallen here! ”

"As long as I destroy the Tinder Source now, the Autobots and Decepticons will soon be gone." Optimus Prime's observation power is absolutely speechless, "The encirclement network of the human army is far from being formed, and we will not fall into the hands of those humans who are full of ambition and desire to be experiments." Please return the source of the spark to us. ”

"You're going to die." There was an inexplicable emotion in the voice of the promise.

"I'm willing to sacrifice myself." Optimus Prime's words were simply shocking.

"If I say, I mean if." There was a gleam in Promise's eyes, "You don't need to make a sacrifice to destroy the source of the fire, are you willing?" ”

"What?!" (To be continued.) )
