Original Pioneers

Full order plus reward, can you add an update for me? This is my first time to recharge some coins at Qidian. I hope the author can work hard.

Very good, interesting, support!

People used bronze instead of iron at first, not because of any prejudice, but because natural copper ore and tin ore can be obtained through simple processes such as burning. However, the iron treated in the same way has too many impurities and is very brittle. Iron meteorites are rare, so it will take a very long time for iron to replace bronze.

The story is quite good. The writing style is a bit immature and has the feel of a running account. This is the type of story I like. I like the feeling of starting from scratch and developing bit by bit.

Many book friends leave after reading it, so you may feel that there are not many people. As long as you work hard, I believe there will be rewards.
