Chapter 1483 (2/2)
At the moment of contact with the dissipative layer, the little flame gradually outlines a red and hot arc on its body. Four circular arc-shaped external engines eject a dark blue flame in the reverse direction, and a light blue shield is stretched in front of it.
Thick cumulonimbus clouds are penetrating directly.
Through the rain curtain lit by flares, the U.S. soldiers looking at the sky opened their eyes one after another, and their pupils twinkled with shock, disbelief and faint panic.
”Shepard What is that? ”
”Tungsten bullet? No, it was A bit? ”
”It's a drill! They must be crazy. Even a diamond bit can't drill through 400 meters of granite! Not to mention the protective belt made of steel The engineers of the 721 army murmured, looking at the star ring trading positions on the mountain with crazy eyes, ”what do they really want to do?”
Drilling 400 meters deep granite with a simple drill bit is indeed fantastic. Even if a large derrick and supporting drilling facilities are added, it will take two or three bits to drill through the 400 meter thick granite stratum.
As for the protective belt made of steel, it is not a problem that the drill can solve. The steel protective belt embedded in xiayanshan granite layer is not ordinary steel, but steel alloy with high cobalt content! It's not impossible to drill through directly with a drill bit, but the construction period will take at least a week
However, only one hour is left for star ring trade.The external engine separated from the ”digger warrior”, and the huge half track chassis hit the center of the radar station, smashing the cement pavement to pieces. As one of the few land vehicles in the ring trade that can be dropped directly from high orbit, this earth digger has absolutely solid armor and stability.
Although he was hit by several anti-aircraft guns when he landed, there was not even a little deep dent on the steel shell coated with tungsten barrier except for a few shallow scratches.
Although people who don't know what star ring trading intends to do, no one dares to risk the safety of the president and senior Pentagon officials. At the same time, the mountain brigades and 721 troops stationed in Xiayan mountain were obviously fierce.
Bullets were shuttling around in the rain, and the American soldiers' offensive wave after wave rushed up. However, nine hundred starring Marines were obviously not going to let them succeed. Under the cover of ghost agents, a bloody killing filled the night.
Every second someone falls.
Not only the U.S. military, but also the starring Marines.
Finally, the ground digger completed the deployment. The huge drill bit was pushed out from the abdomen, and under the traction of the mechanical cantilever, it aimed at the broken concrete pavement directly below, and suddenly roared out the huge sound of tearing rocks. Bean sized pieces of cement splashed like bullets, only to see the track slowly sinking, sinking, sinking
The soil was drilled and soon the bit touched the granite layer.
Looking at the top of the mountain, the 721 army officer held his breath and fixed his eyes on the steel beast.
Even though he knew that the drill bit would be stuck by the granite layer and the drill bit would be broken out by the solid rock mass, he couldn't help beating the drum in his heart.
After all, that's the technology of star ring trade.
God knows what kind of perverse thing this is
