Gao Wu: Practicing Kryptonian Krypton Life, I Can Change the Price

The spiritual energy is revived, and the whole people are highly skilled in martial arts. Kung Fu, weapons, and even city defense formations can all grant strength, but lifespan, pain, and memory are written into invisible bills. On the eve of the martial arts exam, Xu Ran, a maintenance apprentice in the old city, bought a copy of Incomplete Forbidden Technique. He accidentally saw the hidden terms and was able to change the payment method within the equivalent range. He changed "ten years of life lost" to "hunting three strange beasts in one night", and from then on he dismantled exercises, checked contracts, and tracked down the black ledger left by his missing father. But when he, Shen Xingmi, Zhou Lie, Tang Xiaoman and others investigated the deepest part of civilization, they discovered that the prosperity of the core city, border defense weapons and so-called safety techniques may all be secretly paid for by unsuspecting people. When the door reopens and the general ledger is out of control, Xu Ran must answer the last question: If power always has a price, who has the right to sign for others?
