Calling it a checkpoint is in fact an understatement; it refers to the profound restrictions held within the human body.
Like a rope, it firmly binds the potential of the human body, preventing it from being unleashed, and as a result, humans can only remain ordinary and unable to possess certain extraordinary powers.
And these ropes aren't easily broken.
If one were to rely solely on the power gained from self-cultivation to break free, it would undoubtedly be quite difficult.
After all, one's power, when it comes down to it, is still constrained by individual potential, and these ropes were designed to constrain this potential.
In a way, the difficulty of breaking these ropes is comparable to an ordinary person trying to lift themselves off the ground.
The Boundary Breaking Pill, on the other hand, is akin to an external force.
An ordinary person cannot lift themselves up, but if someone comes along and lends a hand, it becomes much easier.
