The lack of sufficient resources to produce the Mobile Base is the biggest challenge Chen Xin faces in promoting his plan.
It's like playing a construction game, where to expand production and upgrade buildings, you first need more resources.
To obtain more resources in the game, you either build more mines or miners, or upgrade mining equipment, and in reality, it's the same.
The country doesn't lack mines, but changes in the natural environment have made many open-pit and small mines unusable, and the remaining operational mines have decreased production due to environmental impacts, leading to insufficient resources for the country in the short term.
There is more than one solution to this problem, but among the effective ways, improving mining tools is undoubtedly a good choice.
The research center where Chen Xin works has projects related to this in its past work.
