"The Blue Star of this era doesn't have any advanced technology for uncovering undersea treasures. Our technology can not only uncover them, but also keep the people of this era from noticing. In particular, most of the supplies you need have to come from the sea. This is only the beginning."
Zhang Hao asked, "Won't this affect the course of history?" He was gradually beginning to understand some of the rules of space-time.
"It will! It will affect it, which is why we have to proceed in secret and do our best to gently guide history onto a space-time branch. If we use too much force, the river of space-time will be violently disturbed, bringing all sorts of trouble."
Zhang Hao asked in confusion, "If we affect the course of history and enter a space-time branch, could something happen to the original main timeline...?"
Mifeng shook his head. "The main space-time timeline can't be shaken. That's one of the rules of space-time. If space-time were a great river and you dug an opening along its bank, a new, smaller river would form. You can think of that smaller river as a space-time branch. The main river won't be affected. Of course, this analogy isn't really accurate, but I don't have the right words to describe it right now. Just make do with that explanation."
Zhang Hao couldn't help marveling. He now understood a little why Mifeng wanted him to establish a bridgehead in Ancient Times. It was like establishing a bridgehead upstream, allowing branches to split off at any moment. Each space-time branch could bring him rich rewards. So that was the rule behind it.
"Every time a space-time branch appears, a corresponding bridgehead appears as well. So, to tell whether a new branch has formed, you just need to
