He could devour machinery to gain various mysterious skills, scan machines to obtain blueprints for manufacturing, and even use his thoughts to achieve unified control of different machines.Thus, he found a 200-ton heavy gas-powered locomotive, towing specially modified storage, planting, production, medical, and living carriages, and embarked on a 320,000-kilometer journey along the planetary orbital rail—charging eastward toward the dawn!
