All the disloyal subject wanted was to take advantage of the kingdom’s fall to pocket the royal treasure. But instead… he took an arrow for the queen and ended up dead. He is awoken in an afterlife by an apostle of god who mistook him for a faithful subject and tells him his job is to restore the fallen kingdom by reliving the historical moments that shaped it. Will he manage to rebuild the kingdom to its most glorious day and go down in history as the true loyal subject or… will his greed get in the way? 3l136r

There were gold and silver treasures…? There weren’t!
Whether there was an enemy invasion or not, he rushed to the gold he was aiming for, taking advantage of the opportunity for the ministers to run away. At the moment when he was about to surrender while weighing the probability of death, he instinctively (?) ran in front of the Queen and was shot by an arrow instead of the Queen.
“Loyalist, you are my last hope!”
Only one chance given to the last loyalist, you have to go back to the past and rebuild the ruined Kingdom!

A good story that doesn't reach it's potential because of poor writing, and an annoying MC, and the quality of the translation doesn't help either.
In any case, the story is interesting, the MC is a sh*tty guy that gets chosen "by mistake" to give a fallen kingdom a second chance to flourish,, so he is teleported to different significative moments in the past to alter the course of history and strengthen the kingdom in the present (when it falls). MC is inconsistent, going from intelligent to dumb and he has an annoying personality, it leads to some good moments but his pointless greed is always getting in the way, something quite common in manhwas and manhuas.
Overall, entertaining but lacking, it's enjoyable at least but that's about it.
