2021.4.10 version update

Part I new content:
1. Add pictures and random prompts when loading.

The second part is game adjustment and bug correction
1. Fixed the problem of community NPC blinking. This occasional bug has been fixed.
2-1 when the protagonist dies in the community, the weapon will be lost and cannot be picked up. This bug has been fixed.
2-2 when the protagonist dies in the community, NPC will appear repeatedly. This bug has been fixed.
3. Fixed the problem of wrong UI layer in some scenarios. This bug has been fixed.

Many players complain that there are few prompts, so the prompt is added when loading. On the one hand, it will not be so boring when loading, on the other hand, it can make players understand the game faster. I think it's just a small update, but I'm tired of doing it. Every little idea may contain unlimited workload. I hope what I do can give you a better experience.

Fixed the gun holding error when snow mountain arrived at the community.
