My Chat Window Is an Interstellar Resource Panel

After transmigrating into a magical world for sixteen years, Lin En's golden finger is a good-for-nothing that can only pop up dialogue boxes. Its memory clears after three seconds, and it can't answer a single question. Then, one late night, on a whim, he types in a cheat code from a childhood game: show me the money. The number in the upper-right corner skyrockets to 999,999. What's more, he discovers he can conjure that blue-white crystal ore out of thin air in the palm of his hand. From black-market crystals to explosive crystal bombs, from crystal-steel cannons to magic-net satellites, while the church's priests are still collecting tithes to ease the suffering of the people, he has already used the mine in his palm to unlock the tech tree of an entire civilization.
