I Became the Richest Man in the World by Fixing Bugs

On the first day of time travel, Chen Buming became the most useless person in the world: he had no system and only had three months left to live. But he can see the bottom of the system. He sees through bugs that others can't fix. He repaired a wheat field that had failed to produce results in three years in ten minutes, and the first pot of gold was three hundred silver. The system was collapsing every day, and he was taking orders every day, from building an acre of wheat fields to an entire street in Gray Domain City. The guild has a monopoly, and the dark web is a trap. There are endless bugs and he can make endless profits. He is a professional when it comes to fixing bugs, and he also gets paid. But the more he repaired it, the more he discovered that behind these bugs, there was a secret more valuable than the richest man.
