This Handyman's Way Is Too Wild

Ling Yi was reborn on a crisis-ridden extraordinary earth, but his identity was a "handyman" that everyone despised. A recognized wasteful profession. However, he has the [Heart of All Karma] hidden in his body, which can ignore industry barriers, swallow up and integrate all professional systems in the world, and cultivate the unique "Source of All Karma"! [Courier]'s path optimization + [Programmer]'s logical sorting = [Efficient footwork] to understand the trajectory of all things! [Doctor]'s quick diagnosis + [Engineer]'s structural insight = [Weakness Insight] that sees through weaknesses at a glance! [Financier]'s risk prediction + [Detective]'s trace tracking = [Crisis Sign] to avoid dead ends in advance! Every seemingly low-level fusion will give birth to miracles beyond imagination! When the invaders from the Thorin civilization arrived and the earth was in danger of being devoured, everyone clung to their own industry barriers and despised the "handymen" who did not do their jobs properly. "How can that handyman with only 1 ETI point dismantle a master-level defensive barrier with his bare hands?" "Isn't he a food delivery guy? Why did he go for heart surgery again?" "Wait a minute, he's not a loser! He's... A professional monster!" The left hand code constructs the rules, the right hand swordsman cuts through the illusion, the foot steps on the wind to travel through the dimensions, and the heart refines finance to gain insight into all things!
