The Chapter of Nothingness is currently the last chapter, the fifth chapter, of the game. In this chapter, there are quite a few hidden treasure chests, so it's definitely worth exploring for the treasure chests. Below, I will tell you where the treasure chest in Chapter 5-2 of The Black Beacon: Chapter of Nothingness is. If you still don't know how to find the hidden treasure chests, be sure to follow my steps closely. The following will provide a detailed guide on obtaining the treasure chests; take a quick look.

I. Sharing the location of the treasure chest in Chapter 5-2 of The Chapter of Nothingness:
1. After entering the second level of Chapter Five, walk a little further and you will see a truck. Go to the left side of the truck, and when you get close, you'll notice light coming from under the vehicle. You can then interact with it. After completing the interaction, a glowing point will appear behind you, continue interacting. Repeat this process several times, and the system will prompt you to play a mini-game. After completing the mini-game, the treasure chest will appear, and you can open it to receive the reward directly.

2. After getting the first treasure chest, head in the direction to the left of the truck. There will be another treasure chest at the bottom of the building by your side. This treasure chest requires no additional actions; you can open it directly to receive the reward.

3. Please note that there are two treasure chests in Chapter 5-2 of The Chapter of Nothingness, and they are one-time only. After opening them for the first time, they won't reappear, making it unnecessary to enter the map again. Additionally, the mission difficulty is not high, so you can collect all the items as you follow the story.

Above is the guide on where to find the treasure chests in Chapter 5-2 of The Black Beacon: Chapter of Nothingness. There are two treasure chests in this chapter, which are relatively easy to find. After your first interaction, both treasure chests will become visible, and they are quite large, making them very easy to locate.
