Chapter 1485 (1/2)

”Forward! Move on

It is impossible to drill a 400 meter thick granite layer with a simple drill bit, but the ”earth digger” standing here is not the one that landed on the surface of Mars. In order to adapt to the complex battlefield environment of Mars and eliminate the devil's nest deeper underground, this digger warrior has been transformed by colonial engineers countless times.

On the side of the original drill bit, a groove with the thickness of thumb is added to connect a container of corrosion-resistant material filled with organic solution.

And the solution in it is devil's acid!

The high-speed rotary corrosion-resistant high cobalt bit throws out the devil's acid solution and penetrates into the rock layer under the bit. Both granite and steel protective belt are easily broken by the drill bit under the corrosion of this acid coating.

The speed of the downward movement was beyond the expectation of all Americans!

When the last layer of protection is broken.

The earth digger smashed heavily into the tunnel in the xiayanshan military base, and the steel gate fell just in front of the drill bit. The ground digger, pushed forward, easily drilled a twisted hole.

Soldiers in exoskeletons descend from the top of the mountain into the tunnel and follow the ”digger” closely with their rifles in their hands.

Ignoring the bullets from the front, the high-speed rotating drill bit directly connects to the gate of xiayanshan military base from one end of the tunnel. The grinding sound of dental acid wrinkled, and the heavy steel plate broke inch by inch with the falling rivets.

In the desperate sight of the soldiers stationed in the military base, the huge alloy gate with a weight of 25 tons and a thickness of two meters was forced to poke a big hole two people wide.

”Protect the president!”

With a roar, the war was on the verge.

However, the last layer of defense of the fort has been broken, and nothing can stop the star ring trading soldiers who rush into the fort.

A row of black exoskeletons passed through the corridor filled with Vos. The soldiers and officers who resisted were put down by the butts or sticks. They kicked open the door of the multi-media projection room and surrounded the president, the Secretary of defense, and other senior American officials who covered their mouths and noses

This time, there was no escape for them.

……

Columbus, front line.

A radio. It's on a sandbag.

Armed with rifles, heavy machine guns, and their faces smeared with black camouflage oil, American soldiers circled around for half a circle, listening to the broadcast on the radio.

All of a sudden, everyone was quiet.

They heard Mike burns Their president's voice.

Compared with when he delivered his inaugural speech and called for war mobilization, his voice lost a lot of vitality and was somewhat dispirited and old. With a feeling of consternation, the American soldiers looked at each other, stopped the gag and listened carefully to every word in the radio.

However, after listening, the expression on their faces was completely frozen

Or in other words, it's completely broken

”Today is the darkest day in American history.”

”Our last fortress, the xiayanshan military base, has been broken.”

”Hundreds of millions of people were involved in this wrong and avoidable war, in which more than 100000 Americans were lost, and now millions of Columbus citizens are suffering from the siege. Generations of efforts have been burned, and our losses can no longer be measured by the Fed's gold. ”

”It's not because of fear of the future, but because it's really time for this war to end.”
