Restoring the Broken Bridge

There is a broken bridge in the southeast of Tullan. When Ugdrasil invaded during the war 100 years ago, the bridge was cut off to buy more time in Tullan. Radeus III preserved the place so everyone could learn a lesson from history.
But recently Lamia Maid Darilla decided to remove the remains of the bridge to build her nest. We need to fight, but the Mayor is worrying that Darilla might tear down the bridge. That is why I received a somewhat unreasonable order to make the bridge safe by reinforcing it. Reinforcement work on a broken bridge? Isn't it funny?

Anyway, I need someone to watch my back while I'm working. So, I want to ask you to dispatch <HFFFA7272>18 Lamia Maids<HFFFFFFFF> near the <HFFFA7272>Broken Bridge<HFFFFFFFF>. Meanwhile, I will work.

Radeus III put the Record of the Prestigious Family into the Broken Bridge to prevent anyone from touching the record. That is why we can't let the bridge collapse.
So, please kill <HFFFA7272>18 Lamia Maids<HFFFFFFFF> near the <HFFFA7272>Broken Bridge<HFFFFFFFF>. Meanwhile, I will do my job.

That was pretty close. I don't know if it'll be enough, but I did hammer some nails into several torn down pieces of wood. Honestly, I don't think it will do. Don't we need another plan?
