Eerie Sequences: I Have a Daily Upgrade System

In 2030, the sun in the sky suddenly began alternating between eerie green and red. The paranormal gradually revived and merged with the real world. The more closely the paranormal world merged with reality, the greater the number and strength of its entities. Cities were the first places to be affected, forcing people to stay away from major urban areas.

As the paranormal descended, the nation's military power began to steadily weaken. At first, some modern weapons could inflict minor damage on the entities, but eventually they could do nothing at all. National communications gradually collapsed. People had no choice but to form convoys and fight for survival on their own. The convoys couldn't stay in one place for long, because the paranormal would keep searching for humans.

A very small number of people might awaken for no apparent reason, or after killing paranormal entities. Humans who awaken supernatural sequences can kill them.

The protagonist has a Daily Upgrade System. Each day, he can claim one white upgrade. Three white upgrades can be exchanged for a green one, and three green ones for a blue one. The upgrade tiers are white, green, blue, purple, and gold.

The daily upgrade can be used on anything, whether it's the protagonist's body, his sequence, or paranormal items.

The protagonist knows that if he just keeps a low profile and survives, he'll eventually become invincible.
