Was fuel expensive?
No.
In a modern industrial society, as long as you had no particular requirements for combustion quality, there were countless liquids that could burn, and they were dirt cheap.
Waste motor oil and waste diesel, for instance. Both caused serious pollution when burned, burned erratically, and were highly toxic. They were unsuitable as everyday fuels, and using them might violate environmental regulations.
But this was another world, and they were practically free for Chris... All he had to do was say on the Online Shopping Platform that he could dispose of them, and vendors would all but give him those liquids.
Concentrated sulfuric acid was inexpensive, too. As an industrial by-product, it cost only six hundred yuan a ton if he ordered more than a hundred tons at once, according to Chris's search on the Online Shopping Platform.

Even if those risking their lives were players or the Railway Corps formed from locals.
Anyone who could do arithmetic would have made the same choice in Chris's position.

The exposed portions were no longer merely rock and human remains, but an unsettling fusion of organic and inorganic forms.
A strange black substance that looked as though it had been smelted formed the main structure, studded with countless pallid bones
