The subsequent mysterious rewards were evidently not as generous as the earlier ones.
However, there were still some surprises among them.
For instance, on December 29th, a batch of fluororubber was sent over, just a day before New Year's Eve.
This type of rubber is highly resistant to high temperatures and chemicals, and has strong resistance to most oils and solvents, making it suitable for car engines, fuel systems, and sealing in chemical plants.
With this batch of rubber, Chen Zhou's dream of handcrafting a steam engine took one step closer to reality.
Besides the rubber, the reward on November 14th was also quite decent, a batch of modern shovels and steel picks.
Chen Zhou had been worried about his self-made shovels wearing out too quickly, and with the limited scrap iron in the warehouse, this reward came just in time.
Although his forging techniques were competent enough, the tools he made were usable but couldn't compare to modern factory products.
