All Things Upgrade Device: from Blood Recovery Pill to Dragon Source Pill

[Fast-paced and cool writing + no Virgin + no heroine + random killings + background of all races] After awakening the F-level talent [Durability] at the beginning, Lin Feng became the laughing stock of the whole school. In addition to his great strength, this talent makes him a coolie. Before he finished his emo, there was a "ding" in his mind: [All Things Upgrading Device] has been activated! Any item can be upgraded! While others had been practicing hard for ten years, Lin Feng clicked on the "Basic Breathing Technique" with a backhand - the quality of the technique soared from broken to legendary level, and the tides of the world were triggered by breathing! Is the elixir not strong enough? An ordinary blood-restoring pill is upgraded to [Legendary Longyuan Pill]. If one is taken into the abdomen, the attributes will skyrocket by 999! The weapon is iron? A chopper, smashed down a million mana points, directly upgraded to [God's Creation·World Destruction], and cut off the galaxy with one knife! Even his useless talent was upgraded from [Durability] to [E-Grade·Super Durability], and then to [D-Level·Copper Skin and Iron Bones]... Until one day, the pressure of the SSS-level talent [Fudo Myooh] came to the battlefield, and all races fell to their knees. Only then did he realize that this system had no upper limit at all. On that day, Blue Star regained all its lost territory. That day, he crushed the void and pointed his sword at the Lord of the Universe.
