The 7000 meters track was just like a strand of seaweed that swayed with the ocean current.
The 500 meters long graphene track connected on both ends by Titanium rings; 14 tracks in total formed the 7000 meters deep sea stairs from the abyss to the surface.
The entire track cost 500 million crystals, almost equivalent to the entire food trade revenue of NAC.
Out of all the equipment, the most expensive was the 15 titanium rings. They not only play a role in fixing the graphene tracks, but they could also freely control the depth of water just like submarines. Based on the direction of the ocean current, the titanium ring can also move through the four angles of the blade engine to move in the opposite direction. This prevents the huge tidal force from tearing the entire graphene track apart.
When the Droplet placed the six meters long, two meters wide oval "elevator" at the bottom of the track, the entire deep ocean mining module was completely deployed.
