My Lifespan Is at the Bottom at the Beginning, I Rely on Level-Up Challenges to Survive

Xu Ansheng accidentally entered the world of high martial arts and activated the "infinite challenge system". When his lifespan reaches the bottom, he must immediately challenge the stronger one; While others were trying hard to break through, he relied on competing with geniuses, racing with monsters, snatching food from ferocious birds, and convincing his enemies to surrender all the way to counterattack. He also brought a system-generated cheating spiritual pet around to do his job, trampling on talented people, flirting with beauties, and beating enemies to death in public.
