Surviving In A Wasteland: I Can Evolve Endlessly

# WASTELAND
A war in 2030 left almost every city on Earth as piles of ruins. The air was severely polluted while water sources were on the brink of completely drying out. The sky was covered by yellow sand, and sunlight could hardly penetrate through it to reach the ground.
Humans who survived the war encountered deadly threats as they struggled to live in such harsh living conditions. When faced with such a cruel reality, Zhou Yuan activated the Unlimited Evolution System.
The main function of this system was to allow everything to evolve infinitely.
For example, the system could enable an ordinary stalk of paddy to grow non-stop under very harsh conditions, thus producing mass amounts of food.
The system could also enable an ordinary freshwater fish to evolve into a purifying freshwater fish that could purify the water it lived in.
The system could even enable non-living things to frenziedly evolve and have unexpected results.
Step by step, with the help of such a powerful system, Zhou Yuan built a new kingdom solely belonging to him amidst the ruins.
