After Qiao Lu gave the order, the 10,000 planetary engines on the wandering earth underwent amazing changes at the same time, the huge metal peaks were restless like hearts, and the complex mechanical parts refurbished the planetary engines from top to bottom.

"It's coming!"

The 3.5 billion people on Earth have watched with excitement and awe as planetary engines change.

This is a day that will go down in history, and this is a day when humanity will start a new journey!

Finally, the deformation of the planetary engine began.

First, the base of the engine suddenly rose from the ground, and from the base that could not be moved, it turned into a giant mechanical limb capable of moving in mid-air, and then fell heavily back to the ground.

The six main brackets of each planetary engine have all been transformed into multi-stage mechanical limbs that can be propelled forward, which means that the 10,000-meter-high stationary engine has been successfully transformed into a giant mechanical fortress that can be moved.

When you see a moving fortress taller than Mount Everest slowly approaching you, you can understand what it's like to literally be on top of Mount Tarzan.

And that's just what happened to the bottom of the planetary engine.

In the middle of the planetary engine, where the original fuel refill site was, a mechanical arm with a giant excavation equipment slowly stretched out and automatically reached for the nearby peak.

The tip of the giant arm dug into the rock as easily as digging tofu, and then with a loud roar, countless rocks were pulled out by the giant excavator, and along the transportation loop that ran through the entire giant arm, the stones were continuously fed into the fuel filling port.

The days of using heavy-duty vehicles to transport minerals to planetary engines are over, and today's planetary engines are self-sufficient, intelligent machines that combine earth engines and mobile miners.

Even a hundred heavy-duty trucks can't match the efficiency of this mechanical giant arm in transporting minerals, let alone as an ultra-heavy excavator.

Finally, and most importantly, the top of the engine, which is where the planetary engine vents are located.

The vents of the planetary engines began to extend upwards layer by layer, forming a shape like a cannon barrel that went straight into the sky, and the top directly entered the stratosphere, pointing directly into the universe at an altitude of more than 20,000 meters.

On Earth, you can only see this barrel extending to the end of the sky, and it is impossible to see the top of the engine unless you are on a high-altitude plane.

It is like the legendary Buzhou Mountain, supporting the weight of heaven and earth.

It's just that there are more than 10,000 such pillars, and they are not used as supports.

Looking at this shape, you know that the target of these planetary engines is only the sea of stars.

"It's ······ Cannons? ”

Qiao Lu looked up at the vent of the planetary engine outside, which had broken through the sky, and asked, this is obviously not used to propel the earth.

Moss replied, "Yes." The planetary engine cannon is ready, a test launch is requested, please indicate. ”

Qiao Lu looked back at the console, a Cybertronian hulk 90,000 kilometers away from the earth was selected by Moss as the target of this test launch, and he could see the power of these Earth cannons with his own eyes.

"Test firing is allowed." Qiao Lu nodded and said.

The nearest three planetary engine cannons began to reorient their vents, and began to gather dazzling blue energy on the vents.

At this moment, three huge blue balls of light shone above the earth, and three blue suns seemed to appear in the sky, illuminating the nearby ground into a blue color.

After about ten seconds of charging, the planetary engine vent was finally launched!

But this time, instead of a continuous pillar of light, a cloud of highly concentrated blue plasma burst through the sky like a cannonball, heading straight for the shipwrecks 90,000 kilometers away.

The three plasma shells hit the space hulk almost simultaneously, and the moment it made contact with the hulk, it expanded and spread into a huge red thermonuclear fireball, engulfing the entire hulk in an instant.

In the ultra-high temperature, which resembles the core of the sun, the space waste ship melts rapidly like wax on fire, leaving almost no solid debris behind the entire ship, all of which are dissolved into incandescent liquid metal and scattered in space.

There seemed to be a small scorching sun in the universe, which continued to flicker for a few seconds before slowly extinguishing.

The location where the original space wreckage was located was almost empty. The entire ship was melted and evaporated in the heat of the thermonuclear explosion, turning into countless pieces of liquid metal that burst out.

This kind of power is really embarrassing.

What is even more outrageous is that there are more than 10,000 such cannons······

"The test launch is complete, and the target has been destroyed." Moss faithfully reported to Jorry.

But Qiao Lu still felt that it was more accurate to say that the target had been evaporated.

"Well done." Qiao Lu took a deep breath and said, the effect this time was really beyond his expectations.

"The test launch is over, and the engine is back to normal condition."

Moss, who was instructed to do so, began to restore the planetary engine vent to its original appearance, after all, there are two forms that are the most important feature of the Tinder lifeform.

The planetary engine, which had retracted its barrel, began to shoot out the original pillar of plasma light again, continuing to propel the Earth slowly.

This is the job of the planetary engine, and the transformation of the tinder will not erase the original role of the machine.

I have to say that this transformation is really a bit more complete than imagined, and it is enough to make Qiao Lu satisfied with the planetary engine to gain the function of moving and mining.

Now the planetary engine can still be used as a ground-based defense cannon, which is not something that Qiao Lu could have imagined at the beginning.

Of course, this form of earth cannon is not without weaknesses, the biggest problem is that superconducting ore must be used as a cannonball, and ordinary fossil fuels are simply not enough to support such a powerful weapon for launch.

If a salvo of 10,000 planetary engines were really used, I am afraid that it would not take a few rounds to shoot out more than 2,000 tons of superconducting ore.

Like the Sword of the Earth, this is also a trick to press the bottom of the box, and you can't use it casually.

It's just that if any alien race dares to attack the wandering earth without a long eye, they can feel the taste of this kind of cannon fire.

The 10,000 Earth Cannons are impermeable, and if you are not satisfied, you can shoot a few more rounds.

We no longer need heroic soldiers to build the Great Wall of flesh and blood to defend our defenses;

Instead, use powerful artillery fire to wipe out the enemy outside the Earth's atmosphere!

Those who violate my borders will be punished even if they are far away!

This is the best consolation for the heroes who have died.
