On the first day of July, Hai Dongli created good news that shocked the Carefree Kingdom.
The engine that he had painstakingly developed had achieved great results.
The production of engines could completely and quickly advance the development of the industrial era.
After Bai Wutong received the news, she immediately ran to the research laboratory with Chu Tianbao.
All the researchers were very interested in Hai Dongli's new research, but they did not know what that big metal object was for.
With the Great Empress here, everyone could finally step into Hai Dongli's laboratory.
Hai Dongli did not know how to speak and gestured excitedly to Bai Wutong, making everyone look confused.
They still did not know what use this thing had.
