A century after the world turned into a game, everyone awakens a class. The top student gets the worst one—just a basic warrior. Laughter. Doubt. A whole school watching him fall. Then his system activates… and everything flips.

Zhang Mu activated the "Eye of Investigation" system in a mysterious forest and discovered its ability to accurately predict monster drop items and probabilities. After defeating a black snake, he unexpectedly obtained a full set of armor with an extremely low drop rate, confirming the system's authenticity and power. Subsequently, Zhang Mu swept through dungeons, clearing multiple bosses and learning powerful skills, upgrading to a magnificent golden battle armor. Finally, he arrived at the Cat Demon Forest to challenge the "Poison Cat King." After eyeing its generous drops, he faced an encirclement by cat demons and unleashed his new skill, "Explosive Flame Slash," initiating the final battle.

This episode tells how protagonist Zhang Mu easily cleared the forest dungeon and quickly leveled up to 20 using his powerful "Epic Skills." The immense commotion he caused in the dungeon amazed passing professional players. Afterward, Zhang Mu headed to the job change hall to transfer classes. His astonishing leveling speed (reaching level 20 on the day of his awakening) broke historical records, leaving the front desk clerk utterly shocked. After successfully transferring classes, Zhang Mu planned to sort out his equipment and head to a new dungeon. Outside the hall, a classmate who recognized Zhang Mu saw him emerge from the job change shrine, sparking intense curiosity and suspicion about his unusual behavior and progress.

This episode follows Zhang Mu as he heads to the exchange to sell the equipment and materials dropped from monsters. At the exchange, he bumps into his high school classmate, Liu Cheng. Liu Cheng, arrogant about his wealthy family background and having awakened a decent profession, mocks Zhang Mu relentlessly, even offering to buy Zhang Mu's equipment at a "high price" as an act of charity. Zhang Mu directly tells Liu Cheng he can't afford it, and then, to everyone's shock, spills out piles of high-level equipment. He ultimately earns a massive 50 million by selling it. Afterward, Zhang Mu purchases potions and ventures alone into the Wolf King Valley dungeon. Meanwhile, astonishing data appears on the profession ranking board in Maple Leaf City: a mysterious individual has risen to over level twenty in just three hours, sparking widespread discussion throughout the city. Everyone speculates that this person is the legendary professional, Su Qingyu.

Zhang Mu enters the wild instance "Wolf King Valley" and rejects an invitation to team up from a veteran player, choosing instead the highest difficulty and entering alone. In the instance, Zhang Mu displays terrifying power, unleashing the ultimate skill "Storm Slash" to instantly kill packs of Swift Wind Giant Wolves, causing his experience points to soar. With the attribute bonuses from his full set of golden equipment, Zhang Mu levels up to 40 in a very short time. To avoid attracting attention, he decides to postpone going to the Job Change Temple. He then discovers a mysterious scroll among the loot.

Zhang Mu unexpectedly obtained an extremely rare "Mythic Profession" scroll. With his "Infinite Drop Rate System," he decided to no longer endure past humiliation and set a goal to level up. Zhang Mu challenged the high-difficulty dungeon "Wolf King Valley" alone and broke the clear record in less than half an hour, shocking the onlookers who had previously mocked him. After obtaining the reward equipment "Cape of Glory," Zhang Mu quickly retreated to avoid the crowd of fanatically adoring players and began to examine the powerful attributes of the god-tier equipment by himself.

Zhang Mu obtains an excellent piece of equipment that not only heals him but also increases his attack power, perfectly fitting his combat style of "the more he fights, the stronger he gets." After preparing himself, he heads to the job change temple to receive his "second job change" quest. The receptionist, upon checking his information, is astonished to discover that Zhang Mu had only awakened and completed his first job change the day before, and is already attempting a second job change today. This leveling speed is simply monstrous. Under the assessment of a testing device, Zhang Mu triggers an extremely difficult "Abyss-level quest" – to dismantle the "Heart of Darkness" hidden within the Dark City of the Flame Canyon. To avoid drawing attention, Zhang Mu lies to the receptionist, claiming the quest is only "difficult." After receiving the receptionist's reminder about the job change item, Zhang Mu leaves with full confidence, ready to face the challenge.

This episode follows Zhang Mu and his teammate Liu Yu as they level up in the Flaming Canyon. They are confronted by three second-turn professionals who claim to have "booked the area" and demand protection fees. Despite the other party's arrogant provocation and Liu Yu's worried pleas, Zhang Mu remains unfazed. He unleashes his powerful lightning ability, causing a celestial phenomenon. The initially arrogant bandits collapse instantly in the face of an insurmountable power gap, begging for mercy and even shifting blame onto each other. However, Zhang Mu coldly declares it's too late and prepares to mete out punishment.

Zhang Mu taught a lesson to three hostile professionals, disabling their equipment before letting them go. Liu Yu, a priest, was impressed by Zhang Mu's power and became his "little follower," trailing him and filled with curiosity about his true level and profession. The two arrived at the dangerous "City of Darkness." Zhang Mu sensed the power of the monsters within and urged Liu Yu not to follow. Liu Yu insisted on providing support as a priest, casting the "Song of Courage" buff on Zhang Mu. Empowered, Zhang Mu displayed astonishing combat prowess and flew directly towards the dark castle suspended above the lava.

Zhang Mu single-handedly takes on an abyss-level dungeon, facing hordes of high-level monsters. He unleashes legendary skills "Beacon Fire Burning City" and "Heaven and Earth Collapse" to annihilate them all. This astonishing feat deeply shakes Liu Yu, who witnesses it firsthand, and also alerts his teammates Li Hao and Chen Xue, who are far away in the outskirts of Maple Leaf City. After the battle, Zhang Mu obtains a wealth of high-level equipment and piles of gold. He then prepares to challenge the core of the dungeon, the "Heart of Darkness," and the hidden boss, the Skeleton General.
