Death Star Difficulty

In the year 2041 of the old calendar, Mars exploded and turned into a strange beast. But 12 towering trees with hearts suddenly appeared on the earth, protecting the earth. People found that those recognized by the big tree would be lowered to the star core and gain power beyond all else. Therefore, the new calendar was established, the old calendar was abolished, and mankind ushered in a new era: divine disaster. But as the power of the big tree continues to weaken, disasters caused by dark sources are erupting everywhere on the earth. The strange beasts transformed from Mars are also gradually awakening. A new crisis is coming. Haha, star core? Blessings come and misfortunes come.
