"Demon Blade."
"It continuously corrodes the user's power, but the more it corrodes, the more it makes the user frenzied. Whether in speed, strength, or reaction, everything will be significantly enhanced."
"Moreover...
after the user stops using it, or if the user suffers fatal damage, it will return all the previously corroded power, as well as the user's own depleted power, all at once."
After returning it, the blade will fall into silence, and will take several hours to revive. The exact number of hours needs testing."
"Apart from that...
it seems there's another feature, which is that it doesn't need to be hung in a place full of human energy for ten months."
In other words, it can be used now...
Indeed, it has absorbed thirty years of life force, what need is there for that ten months of human energy?"
Li Yuan was silent for a while.
