Greedy Snake: from Ancient Cockroach to Mythical Dragon

Biological researcher Lu Xianlin was reborn as an ordinary snake due to improper experiments. When I first came to this world of spiritual energy recovery, I encountered predators from natural enemies, but my devouring system awakened. The system can not only provide basic data and skills, but also lead to projection worlds of different eras. The protagonist eats in the past, in the present world, and in the future. Devouring all things step by step, he became the supreme master spanning the past, present and future.
