Thank you for your answer. I have reached the state I need through modification. Thank you

Open your game folder:

Steam > steamapps > common > Songs of Syx > base > data.zip > data > assets > init > tech.

Here you find many text documents. Chose the one, you want to change. Open it and look for the line LEVEL_COST: and change the following number. With changing the number you change the costs of the technology. Change it in the archive. Don't unpack it. But keep in mind that the mod will overwrite this change, when it is activated.

Alternatively change it within my mod you downloaded.

You find it here:
Steam > steamapps > workshop > content > 1162750 > 2923967741 > V63 > assets > init > tech

Just keep the mod active and your changes will be applied to your game.

I hope, I could help you :)

You're welcome :) Do you mean a boost of technology or only one specific technology?

谢谢您 thank you very much 请问如何我只需要影响科技的修改，应该怎么弄呀？If I only need to influence one piece of technology, how do I do it?

nice mod, thanks. but could fertility be raised as well or growth rate is enough to cover that?
