Delivery worker Lin Yuan is specially recruited into the special management system and awakens the Heaven Rewards Diligence system, rapidly breaking through martial arts realms in the era of spiritual Qi revival. He fights a swarm of beasts alone in the Beast Tide battle, slaughters the Tier 2 peak Iron-armored Frenzied Ape, and reinforces various defense lines to protect the people of the entire realm. Later, Lin Yuan enters the Martial Arts Research Institute, and the Huayu defense system opens basic breathing techniques to all citizens, ushering in an era of universal cultivation. He subsequently leads a team deep into the primitive forest area to contend for the spiritual plant Blood Abyss Bodhi, which can help people break through realms, continuously growing in the tide of the end times and shouldering the heavy responsibility of protecting the entire Huayu realm.
