I don't know when I read this, probably a long time since I can't remember most of the plot scenes.
Plot details I can remember:
There's an engineer who, I think, wants to create an elevator. I don't know if it's an invention or whatsoever but it's a powerful one.
I can't remember where the elevator will go but I'm confident it'll be a planet - that's why it is powerful.
There's a part where he plans to construct it in a mountain. I think that's where tries to build it but a monk tries to sabotage it.
The antagonist is a monk.
Note: Sorry if I only gave little information. That's all I can remember from that story. Maybe some of you already read it and forgot it too, you can edit this question to add more information. I googled all info I can remember but it doesn't match the same book I'm trying to find.
